The first environment refers to the environment with more densely distributed air compressors and more quantity, and the second environment refers to the environment with less sparsely distributed air compressors and less quantity.

In addition, the invention also provides a joint control method of the air compression station, and the joint control method can be realized by the joint control system.

The joint control method of the air compression station comprises the following steps:

in a first environment, acquiring data of a first group of air compression station equipment in the first environment by using a control cabinet, and generating a control instruction by the control cabinet through the acquired data so as to control the first group of air compression station equipment to work; the control cabinet uploads the acquired data to the cloud server;

in a second environment, acquiring data of a second group of air compression station equipment in the second environment by using a data acquisition network manager, and uploading the acquired data to a cloud server;

and the cloud server generates a control instruction according to the acquired data so as to control the second group of air compression station equipment to work.

Specifically, the control cabinet controls the first group of air compression station equipment to work in real time, and the cloud server controls the second group of air compression station equipment to work in non-real time.

Further, the real-time adjustment includes: single-point pressure control, flow matching control, equipment rotation and fault switching; non-real-time adjustments include: planned starting and stopping, equipment rotation, fault starting standby, low-voltage starting and high-voltage stopping.

The following takes the header pressure as an example, with reference to more specific examples. The method is suitable for the industry of air compressors, aims at the scene that air compression station equipment is distributed discretely and cannot be controlled through edge centralization, and adopts a mode of combining cloud control and field control, so that pressure fluctuation of a main pipe is controllable, and energy consumption is reduced.

And 7 air compressors are arranged at a certain air compressor station. Of which 5 were concentrated in the old workshop and 2 in the new workshop. 5 air compressors in an old workshop are matched equipment which can be estimated according to the current factory when the factory is built, and subsequently, due to market expansion, the capacity exceeds the estimation, when the capacity is the highest, 6 air compressors are needed to generate gas, and 1 air compressor is needed to be reserved, so that 2 air compressors are additionally needed. Because the factory building space is limited and the layout is limited, the newly-added 2 air compressors are placed in a new workshop which is 2 kilometers away. And the distance is long, so that centralized field control cannot be performed. Therefore, a method combining cloud control and field control is needed.

And 5 air compressors in the old workshop adopt a field control method. The specific implementation scheme is as follows:

and a pressure transmitter with an output of 485 is arranged at the main pipe to acquire the pressure of the main pipe in real time.

And each device is provided with a data acquisition node which communicates with the device controller/pressure transmitter through 485.

And a control cabinet is installed on site, and the control cabinet is communicated with each acquisition node in a LoRa (remote distance measuring) mode.

And the control cabinet reports data to the cloud end through a 4G route.

The control cabinet carries out single-point pressure control according to the data of real-time collection, namely when the pressure of a main pipe is insufficient, 1 idle device is started, and when the pressure of the main pipe is too high, 1 running device is stopped. And other common control schemes such as: fault switching of standby machines, sequential rotation and the like.

And 2 air compressors in the new workshop adopt a cloud control method. The specific implementation scheme is as follows:

and 2, installing data acquisition nodes at the equipment and communicating with the equipment controller through 485.

And the data acquisition node reports data to the cloud in a 4G mode.

And the cloud end sets a control algorithm, and when the pressure is lower than a high pressure value, at least 1 device is ensured to operate. When the alarm of the over-high pressure is triggered, the machine is shut down completely. When the running equipment is in failure shutdown, another 1 equipment is automatically switched to run. When the running equipment continuously runs for 2 days, another 1 equipment is automatically switched to run.

And the cloud sets a control algorithm, and when low-voltage alarm occurs and the field control end is not idle and normal equipment is started, the other 1 equipment is automatically started until the field end has the equipment which can be started.

The problem that the devices cannot be controlled in a centralized mode due to discrete distribution is solved by a mode of combining cloud control and field control, and the air compression station can continuously save energy by a low-cost and high-efficiency mode.

The field control has the advantages of strong real-time performance, high fault tolerance and low control risk, but needs centralized equipment distribution. The cloud control has the problem of high delay, but has no requirement on equipment distribution. Therefore, the field control is centralized, most devices are adjusted in real time, and the cloud end conducts scheduling with low real-time requirements on a small number of devices, wherein the scheduling comprises planned starting and stopping, device alternation, fault starting standby, low-voltage starting, high-voltage stopping and the like. The two are mutually matched, and the purpose of automatic control of all equipment can be achieved. The problem that the distribution of air compression station equipment cannot be controlled in a centralized manner is solved, and the air compression station can continuously save energy in a low-cost and high-efficiency mode.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
