Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

This embodiment of this application provides a sterilizer's control method, and the sterilizer who uses includes elevation structure, last limit switch, lower limit switch and motor, be equipped with the structure of testing the speed including hall sensor in the pivot of motor, as shown in fig. 1, control method includes can following step:

s101, receiving a control instruction for a lifting structure, wherein the control instruction comprises a target position and a first signal quantity corresponding to the target position.

In this embodiment, the control instruction may be a program instruction, or an instruction with information such as a target position, such as a key instruction under different keys. In this embodiment, when the control command is set as the key command, the first key depression is a down command, and the second key depression is an up command. According to the target position included in the control instruction, the distance value between the target position and the upper limit switch position can be acquired, and after the number of periodic signals corresponding to the rotation of the motor is acquired, the number of first signals is calculated according to the distance value and the number of the periodic signals, namely the number of the signals acquired in the process that the lifting structure moves from the upper limit switch position to the target position.

The number of periodic signals corresponding to the rotation of the motor is the same as the number of magnets in the speed measuring structure due to the fact that the motor rotates for a circle, the number of the signals collected by the Hall sensor is used as the number of the periodic signals, and the distance for driving the lifting structure to move is constant due to the fact that the motor rotates for a circle, so that the distance value between the target position and the upper limit switch position corresponds to the number of the first signals, and the number of the first signals can be obtained through the target position information. For example, if the number of the magnets is 12, the number of the periodic signals is 12, and if the motor rotates one turn to pull the movable structure to move 1cm, 24 signals need to be acquired when the target position is 2cm away from the upper limit switch.

Further, when the target position is the upper limit switch position, the first signal number is a safety number value, for example, in the example having 12 magnets, the safety number value may be set to 12, that is, the lifting structure may be controlled to stop moving when the distance is 1cm from the upper limit switch position. Like this, elevation structure just can stop before limit switch in the short-term access, stops in advance to have reduced the contact to last limit switch, increases last limit switch's life, perhaps upper switch trouble the machine can also normal use. Similarly, when the target position information is the lower limit switch position, because the number of the descending signals of the lifting structure is increased progressively, the first signal number is the difference value between the first signal number corresponding to the first target position above the lower limit switch position and the safety number value. For example, the distance between the first target position above the switch position and the switch position with the upper limit is 60cm, that is, the corresponding first signal number is 720, and since the safety number value is set to 12, the lifting structure is controlled to stop moving at a distance of 1cm from the lower limit switch position, that is, the real-time signal number is 708.

And S102, controlling the lifting structure to move according to the control instruction, and monitoring the quantity of the collected real-time signals in the moving process.

In this embodiment, the control instruction includes an ascending instruction and a descending instruction, and when the instruction is a descending instruction, that is, the ascending and descending structure is controlled to descend from the upper limit switch position to the target position, the real-time signal number is increased; and in order to raise the command, namely, the real-time signal quantity is decreased by controlling the lifting structure to rise from the target position to the position of the upper limit switch. In addition, when the lifting structure reaches the position of the limit switch, the number of the signals is cleared. Therefore, when the lifting structure moves, namely the motor rotates, signals collected by the Hall sensors are counted, the collected signal quantity is compared with a preset value, and the moving speed of the lifting structure is controlled.

S103, when the number of the collected real-time signals reaches a second signal number, the moving speed of the lifting structure is reduced.

In this embodiment, the second signal number plays a role in monitoring deceleration, and since the signal number corresponds to the moving distance of the lifting structure, a safe deceleration distance smaller than the distance between the target positions can be set, the signal number to be decelerated is obtained according to the corresponding relationship, and the difference between the first signal number and the signal number to be decelerated is the second signal number. For example, assuming in step S101 that the second number of signals is set to 60, and the moving speed of the lifting structure is reduced from 240r/min to 120r/min at full speed when the lifting structure is 5cm away from the target position because of the 12 signals collected during one rotation of the motor. Therefore, the lifting structure can be switched to move at a slow speed before reaching the target position, and the influence of inertia on the disinfection cabinet is reduced.

And S104, when the number of the acquired real-time signals reaches a first signal number, namely the lifting structure reaches the target position, controlling the lifting structure to stop moving. The lifting structure moves at the decelerated speed, when the signal quantity reaches the first signal quantity, the lifting structure is controlled to reach the target position, and the lifting structure is controlled to stop moving.

Therefore, the above-mentioned embodiment that this application provided, through the signal quantity that monitoring elevation structure removal in-process produced to according to the relation between target position and the signal quantity, control the position and the translation rate that elevation structure reachd, realize the effect that the layering stops, and carry out deceleration treatment to elevation structure before stopping, reduce elevation structure's inertia, avoid causing the harm to the sterilizer.

As shown in fig. 2, in another embodiment provided by the present application, before controlling the lifting structure to move up and down through the control command, the corresponding relationship between the target position and the first signal quantity is established according to the distance relationship between each target position on the disinfection cabinet and the positions of the upper and lower limit switches, which may include the following steps:

s201, whether the lifting structure is located at the upper limit switch position or not is detected, and if not, the lifting structure is controlled to move upwards to the upper limit switch position. When the lifting structure reaches the position of the limit switch, the signal quantity is reset, and the statistics of the subsequent signal quantity is facilitated.

And S202, receiving a descending instruction, controlling the lifting structure to descend from the position of the upper limit switch, and recording the quantity of signals collected by the Hall sensor in an accumulated mode. The key lamp corresponding to the target position flashes quickly to prompt that a descending instruction can be sent out, the descending instruction is sent out through key operation, the motor rotates reversely according to the descending instruction, the lifting structure descends, the key lamp flashes slowly at the moment, and the real-time signal quantity begins to be recorded.

And S203, controlling the lifting structure to stop when a target position is reached, and recording the accumulated signal quantity to obtain a first signal quantity corresponding to the target position. After the target position is reached, the corresponding relation between the target position and the first signal quantity is established based on key operation, and at the moment, a key lamp corresponding to the target position is normally on, so that the position setting is finished. Because the number of the recorded signals is accumulated, when a target position is reached, the first signal number corresponds to the distance of the target reaching the upper limit switch position, so that the first signal numbers according to the ascending and descending of the lifting structure are the same, namely, the ascending and descending of the lifting structure can be uniformly controlled.
