In order to solve the problem of too high cost caused by too thick wire diameter of a bus cable for supplying power to multiple rows of energy dissipation devices, the application provides a control system for multiple rows of energy dissipation devices, and the control system for multiple rows of energy dissipation devices may include: a plurality of rows of energy consuming devices 1, each row of said energy consuming devices 1 comprising: an energy consuming unit 11; a detection unit 13 for detecting a state of the energy consuming device 1; a power monitoring unit 14, configured to monitor an operating power of the row of energy consuming devices 1 when the energy consuming units 11 in the row of energy consuming devices 1 operate; and the group controller 2 determines, according to the detection unit 13 of each row of the energy consumption devices 1, that the energy consumption units 11 in the energy consumption devices 1 to be operated are operated, and controls the operating rows of the energy consumption units 11 to be operated and then operates according to a preset strategy time division when the power monitoring unit 14 monitors that the total operating power of the operating rows of the energy consumption devices 1 is smaller than a preset power limit value. The preset power limit value may be a maximum power value that can be borne by a bus cable 5 that supplies power to the plurality of rows of energy consumption devices 1.

In one embodiment, the multi-row energy consuming device control system may include a tracking photovoltaic control system. When the multi-row energy consumption device control system is a tracking photovoltaic control system, fig. 1 is a schematic structural diagram of the tracking photovoltaic control system in the embodiment of the present invention, and as shown in fig. 1, the energy consumption device 1 includes a photovoltaic support, a photovoltaic panel, and an execution structure 12 driven by the servo motor. The executing structure 12 is used for driving the corresponding photovoltaic panel to rotate. The detection unit 13 includes an inclination sensor for detecting an inclination of the photovoltaic panel. The power monitoring unit 14 includes a power monitor for monitoring the operating power of the photovoltaic panels in the row of photovoltaic racks when the photovoltaic panels rotate.

In this embodiment, as shown in fig. 1, a plurality of rows of photovoltaic supports form a group of photovoltaic supports, and the group controller 2 is configured to collect data of the group of photovoltaic supports and implement corresponding control. For example, N rows of photovoltaic racks form a group of photovoltaic racks, and the group controller 2 is configured to collect data of the N rows of photovoltaic racks and implement corresponding control.

As shown in fig. 1, each row of photovoltaic racks may include: a plurality of servo motors; a photovoltaic panel; an actuating structure 12 in transmission with the servo motor; a tilt sensor; a power monitor. The servo motor drives the executing structure 12, and the executing structure 12 further drives the corresponding photovoltaic panel to rotate, so that the inclination angle of the photovoltaic panel is adjusted. The inclination angle sensor is used for detecting the inclination angle of the photovoltaic panels in the corresponding row. The inclination angle sensor is electrically or communicatively connected to the group controller 2, for example via an RS485 communication bus. The power monitor is used for monitoring the operating power of the row of photovoltaic supports when the photovoltaic panels in the row of photovoltaic supports rotate. The power monitor is electrically connected to the group controller 2 so as to upload the real-time operating power of the photovoltaic rack to the group controller 2. The group controller 2 is electrically connected with the servo motors in each row of photovoltaic supports, so that the servo motors in the photovoltaic supports in multiple rows are managed through the communication bus.

As shown in fig. 1, the tracking photovoltaic control system may also include a bus cable 5 that provides power to the rows of photovoltaic racks. The plurality of servo motors in each row of photovoltaic supports are connected through cables, and the bus cables 5 can be connected to the middle of the cables through the branch cables 6, so that power supply extends from the middle of each row to two sides to reduce the voltage drop on the bus cables 5 and the branch cables 6.

As shown in fig. 1, the tracking photovoltaic control system may further include a master controller 3 for controlling the plurality of group controllers 2. Fig. 3 is a flowchart of steps of configuration of the tracking photovoltaic control system in the embodiment of the present invention, and as shown in fig. 3, the following configuration steps need to be completed by the upper computer software 4 in an initial operation stage of the tracking photovoltaic control system: s201: configuring the operation parameters of each group of controllers 2, which can include the tracking operation parameters (such as longitude and latitude coordinates, time zones, installation deviation of each sub-row of machines, strategy control angles and the like) of a conventional system and the row information of subordinate servo motors; s202: the number N (N is a positive integer) of rows of photovoltaic supports hung under each group of controllers 2 can be configured according to field installation conditions; s203: the number of servo motors in each row of the 1-N rows can be respectively set to be M1-Mn (M1-Mn are positive integers); s204: after that, the upper computer software 4 is downloaded to each group controller 2 through the system network after the configuration is finished; s205: thereafter, the group controller 2 synchronizes the line information of each line of servomotors to the servomotors.

The group controller 2 can determine the photovoltaic supports to be rotated according to the tilt angle sensors of each row of photovoltaic supports and rotate the photovoltaic supports, and when the power monitor obtains that the total operating power of the photovoltaic supports to be rotated is smaller than a preset power limiting value, the photovoltaic supports in the rotating process are controlled to rotate according to a preset strategy time division.

That is, the group controller 2 determines the photovoltaic rack to be rotated and rotates according to the inclination angle of the photovoltaic panel at this time obtained by the inclination angle sensor of each row of photovoltaic racks and the inclination angle that the photovoltaic panel should be at this time and stored in advance by the system, determines the row of photovoltaic racks as the photovoltaic rack to be rotated if the difference between the two exceeds a preset threshold, and determines that the row of photovoltaic racks does not need to be rotated if the difference between the two does not exceed the preset threshold. After acquiring the rows of photovoltaic supports needing to rotate, the group controller 2 controls servo motors in the rows of photovoltaic supports to rotate so as to enable the photovoltaic panels in the rows of photovoltaic supports to rotate. At the moment, the average power of each row of photovoltaic supports in the current running rotation can be calculated in real time through the power monitor. When the total operating power of the photovoltaic supports which rotate is obtained by the power monitor is larger than a preset power limiting value, the photovoltaic supports which rotate are controlled to rotate according to a preset strategy in a time sharing mode. The preset power limit value is the maximum power value that the bus cable 5 supplying power to the group of rows of photovoltaic racks can withstand.

In the multi-row energy consuming device control system, the preset strategy includes: if the total power of the multiple rotating rows of energy consuming devices 1 monitored by the power monitoring unit 14 is greater than a preset power limit value, controlling the running energy consuming devices 1 with relatively low priority to stop running according to the priority conditions of the different rows of energy consuming devices 1, so as to reduce the number of the rows of the running energy consuming devices 1 until the total power of the multiple running rows of energy consuming devices 1 monitored by the power monitoring unit 14 is greater than or equal to the preset power limit value.

In one embodiment, when the multi-row energy consumption device 1 control system is a tracking photovoltaic control system, the preset strategy may include: and if the total power of the photovoltaic supports for rotating obtained by the power monitor is greater than the preset power limit value, controlling the rotating photovoltaic supports with relatively low priority to stop rotating according to the priority conditions of the photovoltaic supports in different rows so as to reduce the row number of the rotating photovoltaic supports until the total power of the photovoltaic supports for rotating obtained by the power monitor is greater than or equal to the preset power limit value.

For example, fig. 4 is a schematic flow chart of determining the number of rows of the photovoltaic supports that can be operated in one embodiment, as shown in fig. 4, when the total power of the photovoltaic supports that are obtained by the power monitor to rotate is greater than the preset power limit value, the rotating photovoltaic support with the lowest priority can be controlled to stop rotating according to the priority conditions of the photovoltaic supports in different rows, so as to reduce the number of rows of the rotating photovoltaic supports, and then it is determined whether the total power of the photovoltaic supports that are obtained by the power monitor to rotate is greater than the preset power limit value, if so, the number of rows of the rotating photovoltaic supports is reduced by 1, and so on. Until the total power of the photovoltaic bracket which rotates and is obtained by the power monitor is more than or equal to a preset power limit value.

When the rotation of part of the operating energy consumption devices 1 is completed, the total power of the operating energy consumption devices 1 may be reduced, and the preset strategy may further include: and when the total power of the energy consumption devices 1 which are monitored by the power monitoring unit 14 and run by subtracting the preset power limit value is greater than the average running power of the energy consumption devices 1 in a single row, controlling the energy consumption devices 1 which have relatively high priority and need to run but stop to run according to the priority conditions of the energy consumption devices 1 in different rows.

In one embodiment, when the control system of the multi-row energy consumption device 1 is a tracking photovoltaic control system, after the rotation of the partial rotating photovoltaic support is completed, the total power of the rotating photovoltaic support is reduced, and therefore, the preset strategy may include: and if the total power of the photovoltaic supports which rotate is obtained by subtracting the power monitor from the preset power limit value is greater than the average operating power of the single-row photovoltaic supports, controlling the photovoltaic supports which have relatively high priority and need to rotate but stop to rotate according to the priority conditions of the different rows of photovoltaic supports.

For example, as shown in fig. 4, if the total power of the photovoltaic supports that rotate obtained by subtracting the power monitor from the preset power limit value is greater than the average operating power of a single row of photovoltaic supports, the photovoltaic support that needs to rotate but stops and has the highest priority is controlled to rotate according to the priority conditions of the photovoltaic supports in different rows, so as to increase the row number of the photovoltaic supports that are rotating by 1. And then, judging whether the total power of the photovoltaic supports which rotate is obtained by subtracting the power monitor from the preset power limit value is larger than the average running power of the single-row photovoltaic supports, if so, controlling the photovoltaic support which has the highest priority and needs to rotate but stops to rotate according to the priority conditions of the photovoltaic supports in different rows so as to increase the row number of the photovoltaic supports which rotate by 1, and so on.

Further, the preset policy may further include: the priority of the energy consumption device 1 whose operation is completed is lowered to the minimum, and the priority of the energy consumption device 1 which needs to be operated but does not complete the operation is raised.

In one embodiment, when the control system of the multiple rows of energy consumption devices 1 is a tracking photovoltaic control system, in a preset strategy, as the rotation of one row of photovoltaic supports is completed, the priority of the photovoltaic supports which are rotated is required to be reduced to the lowest, and the priority of the photovoltaic supports which are rotated but not rotated is increased, so that the priorities of the photovoltaic supports under different conditions are adjusted to obtain a reasonable priority ranking.

For example, the priority of the rows of photovoltaic racks that need to be rotated can be divided into two parts, one part being a ready priority and the other part being an operation priority, wherein the operation priority is higher than the ready priority. In the operation priority, the higher the priority value is, the higher the priority degree is; in the thread priority, the larger the priority value, the higher the priority.

Fig. 5 is a schematic flow chart of controlling the photovoltaic supports that need to rotate but do not rotate to rotate after partial rotation of M rows of photovoltaic supports is completed in a specific embodiment, and as shown in fig. 5, the tracking photovoltaic control system has the photovoltaic panels with N rows of photovoltaic supports, and the preset power limit value only supports the photovoltaic panels of the M rows of photovoltaic supports at most to rotate simultaneously (N, M is a positive integer, M < N), and the number of rows of photovoltaic supports that need to rotate is greater than M rows, so all the photovoltaic supports that need to rotate cannot rotate simultaneously. At this time, the N rows of photovoltaic supports are planned in ready priority, for example, the N rows of photovoltaic supports can be coded according to the number of rows during initial setting, and the smaller the number of rows, the higher the initial ready priority is; the reverse operation is also possible. Assuming that the number of the ready priority levels is at most P, and P > N, the ready priority levels of the photovoltaic supports which are numbered from 1 to N and need to be rotated can be sequentially set to P-1 to P-N. When the photovoltaic supports which need to rotate all rotate, the priority of the photovoltaic supports which need to rotate can be changed into the operation priority, the other photovoltaic supports can be changed into the ready priority, according to the operation, the N-M rows of photovoltaic supports stop rotating, and the M rows of photovoltaic supports rotate. When several rows of the M rows of the photovoltaic supports are rotated, the operation priorities of the rotated rows of the photovoltaic supports are changed into ready priorities and 0, the priorities of the rotated rows of the photovoltaic supports which are not rotated are sequentially adjusted to the priorities of the rotated rows of the photovoltaic supports, and the priorities are sequentially decreased in a descending manner, so that non-repetition is realized. When several rows of photovoltaic supports in a certain M row rotate, a rotatable idle position exists, whether a photovoltaic support with a non-0 operation priority and which is not rotated exists is searched, and if the photovoltaic support with a high priority in the operation priority is firstly placed in a rotating state, the photovoltaic support is inquired again. If not, searching other rows of photovoltaic supports which are in the ready state and do not rotate, and along with the time lapse, the photovoltaic supports which are in the ready state and do not rotate in the previous rows may also need to rotate, so that the inclination angle of the photovoltaic panel is proper, the photovoltaic supports which are in the ready priority rotate first with the priority value being high, and the like until all the rows of photovoltaic supports which need to rotate complete the related rotation action in a time sharing manner. In a long period, the N rows of photovoltaic supports all need to be rotated at least once to bring the tilt angle of their own photovoltaic panel within a suitable range.

Fig. 6 is a control flow diagram for tracking other functions of the photovoltaic control system in an embodiment, as shown in fig. 6, when the group controller 2 controls other rows of non-rotated photovoltaic racks in the ready state to rotate, the ready priority corresponding to the row of photovoltaic racks is cleared or cleared, and is changed into the operation priority, and the priority can be set to 1.

As shown in fig. 6, during the operation of the tracking photovoltaic control system, the group controller 2 periodically collects data of the tilt sensors in each row of the photovoltaic supports, and simultaneously collects operation information of each servo motor. The group controller 2 periodically calculates the absolute value of the deviation value between the inclination angle sensors with subordinate numbers of 1 to N and the current operation angle set value, when the absolute value exceeds the rotation angle deviation value set by the system, if the servo motors of the photovoltaic support rows normally operate, a rotation angle command is issued, and each servo motor rotates according to the command direction. The group controller 2 periodically calculates the absolute value of the deviation value between the corresponding tilt angle sensor of the row of photovoltaic supports and the current operating angle set value, judges whether the difference value is within the rotation precision control range in the rotation process, and judges whether the servo motors of the row of photovoltaic supports have communication faults or other faults. If the photovoltaic support servo motor nodes are lost or failed within the rotation precision control range or if the group controller 2 detects that the photovoltaic support servo motor nodes are lost or failed, a stop command is issued to all the servo motors of the single photovoltaic support, and each servo motor stops the current rotation after receiving the stop command. In the operation process, the group controller 2 further judges whether the row of photovoltaic supports needs to be suspended, if the row needs to be suspended, the group controller 2 issues a stop command to all the servo motors of the single row of photovoltaic supports, and each servo motor stops the current rotation after receiving the stop command, so that the current operation priority can be maintained, the row rotation state is set to be non-rotation, and the next start is waited.

The present application further provides a method for controlling a multi-row energy consuming device control system, fig. 2 is a flowchart illustrating steps of the method for controlling the multi-row energy consuming device control system, and as shown in fig. 2, the method for controlling the multi-row energy consuming device control system may include the following steps:

s101: and determining the energy consumption devices to be operated according to the detection unit of each row of energy consumption devices and operating the energy consumption devices.

In this step, the energy consuming devices to be operated are determined and operated according to the states of the corresponding energy consuming devices detected by the detecting units of each row of energy consuming devices. If the state of the corresponding energy dissipation device detected by the detection unit meets the preset requirement, the energy dissipation device needs to operate.

In one embodiment, the photovoltaic supports to be rotated can be determined according to the inclination angle sensor of each row of photovoltaic supports and can be rotated. In this step, the photovoltaic support needing to rotate is determined according to the inclination angle of the photovoltaic panel at the moment obtained by the inclination angle sensor of each row of photovoltaic supports and the inclination angle which is stored in advance by the system and at which the photovoltaic panel should be located at the moment, the photovoltaic support is determined to be the photovoltaic support needing to rotate if the difference value between the two is greater than a preset threshold value, and the photovoltaic support does not need to rotate if the difference value between the two is not greater than the preset threshold value. After a plurality of rows of photovoltaic supports needing to rotate are obtained, servo motors in the rows of photovoltaic supports are controlled to rotate, and therefore photovoltaic panels in the rows of photovoltaic supports rotate.

S102: and the group controller acquires the operating power of the energy consumption devices when the energy consumption units in the energy consumption devices in each row operate, wherein the operating power is acquired by the power monitoring units in the energy consumption devices in each row. After step S101, the average power of each row of energy consuming devices currently in operation may be calculated in real time by the power monitoring unit.

In one embodiment, the group controller collects the operating power of the photovoltaic rack during rotation of the photovoltaic panels in each row of photovoltaic racks, as acquired by the power monitors in each row of photovoltaic racks. After step S101, the average power of each row of photovoltaic racks currently in operation rotation can be calculated in real time by the power monitor.

S103: when the total operating power of the operating multiple rows of energy consumption devices is larger than a preset power limit value, the operating energy consumption devices with relatively low priority levels are controlled to stop rotating according to the priority level conditions of the different rows of energy consumption devices, so that the row number of the operating energy consumption devices is reduced.

In one embodiment, when the total operating power of the photovoltaic supports performing rotation is greater than a preset power limit value, the rotating photovoltaic supports with relatively low priority levels are controlled to stop rotating according to the priority conditions of the photovoltaic supports in different rows, so that the row number of the rotating photovoltaic supports is reduced. Further, the total power of the photovoltaic support which rotates is obtained by the power monitor is larger than or equal to a preset power limit value. The specific process for implementing the above steps can be referred to the above description, and is not repeated herein. .

S104: when the total power of the multiple rows of energy consumption devices which are monitored by the power monitoring unit and run by the preset power limit value is greater than the average running power of the single row of energy consumption devices, the energy consumption devices which are required to run and have relatively high priority and are stopped are controlled to run according to the priority conditions of the different rows of energy consumption devices.

In one embodiment, when the total power of the photovoltaic supports which are subjected to rotation obtained by subtracting the power monitor from the preset power limit value is greater than the average operating power of the single-row photovoltaic supports, the photovoltaic supports which are relatively high in priority and need to rotate but stop are controlled to rotate according to the priority conditions of the different rows of photovoltaic supports. The specific process for implementing the above steps can be referred to the above description, and is not repeated herein. .

When the rotation of the partial rotating photovoltaic support is completed, the total power of the rotating photovoltaic support is reduced, and therefore, step S104 may be performed.

In this step, the photovoltaic support which has the highest priority and needs to rotate but stops can be controlled to rotate according to the priority conditions of the photovoltaic supports in different rows. As a practical matter, if the servomotor of the photovoltaic support which is relatively high in priority and needs to be rotated but is stopped fails, the servomotor which controls the photovoltaic support which is relatively high in priority and needs to be rotated but is stopped may be stopped and the priority of the photovoltaic support is excluded. As a practical matter, in the operation process, if it is required that a certain row of photovoltaic supports suspend operation, a stop command may be issued to all the servo motors of the single row of photovoltaic supports by the group controller, and each servo motor stops current rotation after receiving the stop command, so that the current operation priority of the single row of photovoltaic supports may be maintained, and the rotation state of the row of photovoltaic supports is set to be non-rotation, and the next start is waited.

S105: the priority of the energy consumption devices which are operated completely is reduced to the lowest, and the priority of the energy consumption devices which need to be operated but are not operated completely is increased.

In one embodiment, the priority of the photovoltaic support that is subjected to rotation completion is reduced to the minimum, and the priority of the photovoltaic support that needs to be rotated but does not complete rotation is increased. When the rotation of the photovoltaic support with the partial rotation is completed, the tracking photovoltaic control system needs to readjust the priority of the photovoltaic support, so step S105 can be executed. The specific process for implementing the above steps can be referred to the above description, and is not repeated herein.

The multi-row energy consumption device control system and the control method thereof can monitor and manage the operation power of each row of energy consumption devices, and the group controller adjusts the row number of the energy consumption devices needing to operate according to the power control and priority control strategy of each row of energy consumption devices, so that the intellectualization and the reliability of the multi-row energy consumption device control system are improved. In addition, the wire diameter of a bus cable for supplying power to the multi-row energy consumption device control system on the same line can be greatly reduced, the overall cost of the multi-row energy consumption device control system is reduced, the economical efficiency of the system is improved, and the power supply capacity of the system power supply cable is effectively utilized.
