[0030] Please refer to Figure 1 to Figure 2 The integrated plate storage control system (hereinafter referred to as “control system”) shown in one embodiment of the present application includes a control module 1, a drive module 2 and a collection module 3.

[0031] The control module 1 includes a main control unit 11 and a sub-control unit 12 which are integrally arranged and connected by signals, wherein the main control unit 11 is used to perform logic control on various parts of the control system, and coordinate the working order and mode of each actuator according to the preset algorithm and logical relationship, while the sub-control unit 12 is the bottom drive, which is used to control the movement of the drive module 2 according to the control signal of the main control unit 11. It is a prior art and will not be described in detail here.

[0032] The driving module 2 is connected to the sub-control unit 12 by signals. The driving module 2 includes a first driving unit and a second driving unit. The first driving unit and the second driving unit are used to drive the target to move in different directions respectively. In this embodiment, the target is a plate to be stored.

[0033] Specifically, one of the first driving unit and the second driving unit is used to drive the target to move in the height direction, and the other of the first driving unit and the second driving unit is used to drive the target to move in the horizontal direction. In a vertical single warehouse, the storage of plates is mainly carried out by lifting in the height direction to transport the plates to a specified height and moving in the horizontal direction to place the plates in a specified storage position. The specific driving directions of the first driving unit and the second driving unit can be set as needed and are not limited here.

[0034] The second driving unit is disposed on the first driving unit, and the first driving unit drives the object and the second driving unit to move in the height direction.

[0035] In this embodiment, the first drive unit and the second drive unit have similar structures, and include a drive motor, a guide rail, and a carrying fixture. The drive motor drives the carrying fixture to move along the extension direction of the guide rail. The guide rail of the first drive unit is arranged along the height direction. The second drive unit is arranged on the carrying fixture of the first drive unit. The guide rail of the second drive unit is arranged horizontally. The carrying fixture of the second drive unit is used to carry the plate. The first drive unit drives the second drive unit to move the plate to a specified height, and the second drive unit stores the plate to a specified storage position.

[0036] In other embodiments, the second drive unit may also be a robot or other fixed-point grabbing device, and the first drive unit and the second drive unit are separately provided, the first drive unit moves the plate to a specified height, and the second drive unit grabs the plate to a specified storage position.

[0037] The acquisition module 3 is used to collect the driving pulse of the driving module 2 and the position information of the target; the main control unit 11 is connected to the acquisition module 3 signal, and according to the acquisition result of the acquisition module 3, the sub-control unit 12 controls the first drive unit and the second drive unit to start or stop. Among them, the acquisition module 3 collects the driving pulse of the driving motor and feeds it back to the main control unit 11. The main control unit 11 calculates the moving distance of the driving motor driven target according to the driving pulse, and then performs a two-way redundancy check with the position information of the target collected by the acquisition unit, thereby improving the accuracy of the variable frequency speed regulation of the driving motor. It is a prior art and will not be described in detail here.

[0038] The acquisition module 3 includes a pulse acquisition unit and a position acquisition unit, wherein the pulse acquisition unit is arranged on the first driving unit, and the position acquisition unit is arranged on the first driving unit. Since the moving distance in the height direction is uncertain each time, and the moving distance in the horizontal direction is fixed, in this embodiment, the driving pulse of the first driving unit and the position information of the plate when moving in the height direction are collected to ensure that the plate moves to the specified position.

[0039] In other embodiments, in order to ensure that the plate is stored at the designated position, the pulse collection unit can also be separately set on the second drive unit, and by collecting the driving pulse of the second drive unit, it is ensured that the second drive unit horizontally moves the plate to the designated position, thereby improving the accuracy of the drive control. In addition, the pulse collection unit can be set on both the first drive unit and the second drive unit to determine the distance that the first drive unit and the second drive unit drive the plate to move in the height direction and the horizontal direction.

[0040] The pulse acquisition unit is any one of a photoelectric speed sensor, a magnetic sensor, a Hall effect sensor, and an encoder, and the position acquisition unit is a magnetic scale, which is a prior art and will not be described in detail here.

[0041] The control system also includes at least one slave module 4, which is used to monitor the working status of the drive module 2.

The model of the main control unit 11 can be selected according to the number and type of communication interfaces required, and is not specifically limited here.

[0043] The slave module 4 includes a monitoring unit, a communication unit, a starting unit, a starting unit and a control panel. The monitoring unit is used to monitor the working state of the driving module 2, including the current, voltage, speed, temperature, etc. of the driving motor. The communication unit is used to communicate with the main control unit 11. The communication unit includes wireless communication and wired communication. The main control unit 11 is connected to the cloud control platform through wireless communication, and the data collected by the main control unit 11 is transmitted to the cloud control platform to realize remote control monitoring.

[0044] The start unit is used to start or stop the drive module 2; specifically, the start unit is a relay, which is used to control the driving or stopping of the drive motor to realize automatic storage. In addition, the start unit is also used to start and stop the frequency converter to realize accurate control of the motor speed, and provide protection functions such as overload protection and short circuit protection to ensure the safe operation of the control system.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
