[0041] The first photoelectric sensor is used to detect whether the material has arrived. If the first control unit receives the electrical signal of the first photoelectric sensor, that is, detects the arrival of the material, the first control unit drives the motor to control the movement of the conveyor belt; the second photoelectric sensor is used to detect whether the goods have arrived at the material picking point.

By using a PLC to control the optocoupler PC817, and then controlling the relay through the optocoupler, effective signal isolation is achieved.

[0043] The laser displacement sensor is used to detect the distance of an object. The output signal is a current signal. Through the current-to-voltage conversion module, a 0-5V voltage signal is output and input into the analog input channel of the PLC.

[0053] In this embodiment, the third control unit is connected to the unloading robot arm signal through DSQC652, and the third control unit is connected to the unloading robot arm control through the network port;

[0054] Specifically, the initial position of the unloading robot arm, the arrival at the unloading point, and the control cylinder status are transmitted to the PLC through DSQC652. The PLC sends the position information of the robot arm's movement through the network port to complete the information interaction and control the unloading robot arm to grab the goods and place them in the corresponding warehouse.

[0055] In this embodiment, the detection module is a third photoelectric sensor, and the third photoelectric sensor is connected to the third control unit through a signal input module;

[0056] Specifically, the warehouse corresponding to the warehousing system has a length, width and height of 100 cm, 20 cm and 100 cm respectively, with a total of 16 storage locations. Each storage location is installed with a third photoelectric sensor, that is, a total of 16 third photoelectric sensors are installed to facilitate the PLC to power on and detect the status of each storage location.
