The sorting trolley 3 sorts the goods 8 to the corresponding sorting outlets 4. The sorting outlets 4 are connected to the middle main line section 2 and are inclined and arranged on both sides of the middle main line section 2. The distance between the sorting outlets 4 is 750 mm;
[0033] See Figure 2 , the electrical control device includes a strong electricity control cabinet, a host computer, a main control unit, a sorting unit, a sorting outlet processing unit, a camera 6, a sorting trolley control unit, a photoelectric sensor, a servo motor driver, a sorting outlet sensor, an ID sensor, a sorting outlet indicator light, and a sorting outlet button. The camera 6 is arranged on the overhead rack 5. The strong electricity control cabinet is connected to the host computer through an RS485 communication line. The camera 6 is connected to the host computer through a network cable. The host computer is connected to the main control unit through an RS232 serial port line. The sorting outlet processing unit is connected to the main control unit through an RS485 communication line. The photoelectric sensor and the servo motor driver are both connected to the main control unit through a cable. The sorting unit is connected to the main control unit through a wireless 433 communication line. The sorting trolley control unit and the ID detection sensor are connected to the sorting unit. The sorting outlet sensor is connected to the sorting outlet processing unit. The sorting outlet sensor uses a diffuse reflection photoelectric sensor. The trigger port of the camera 6 is connected to the main control unit;
[0034] The button is connected to the input port of the sorting outlet processing unit to prohibit the sorting of the goods 8 to the sorting outlet 4. The indicator light is connected to the output port of the sorting outlet processing unit. The sorting outlet indicator light includes red, yellow, and green indicator lights, which respectively indicate the abnormal state, bag full state, and normal sorting state of the sorting outlet 4. One sorting outlet processing unit can be connected to at most 8 indicator lights, buttons, and sorting outlet sensors of the sorting outlets 4;
[0035] The 4 sequentially arranged sorting trolley control units form a group, which is matched with a sorting unit and an ID detection sensor. The ID detection sensor is arranged on the first sorting trolley 3 controlled by the sorting unit;
[0036] See Figure 3 , the photoelectric sensors include a main line photoelectric sensor 7, a loading photoelectric sensor, a center hole spacing photoelectric sensor of the loading belt, and a long part detection photoelectric sensor 9.

[0038] Working principle: Manual loading is adopted in the loading section 1. During the operation of the loading belt, personnel place the goods 8 with the label side up. After being detected by the long part detection photoelectric sensor 9, the goods enter the camera 6 for photo identification area. After identification, they run with the loading belt to the junction of the main line section 2. The main line section 2 is composed of multiple trolleys in parallel combination. The goods 8 processed by photo in the loading section 1 fall onto the main line trolleys. After the trolley passes through the specific sorting port 4, the goods 8 are sorted to the sorting port 4. When the goods 8 in the sorting port 4 accumulate to a certain height, that is, the sorting port 4 is full, the goods 8 block the diffuse reflection photoelectric sensor of the sorting port, and the color of the indicator light of this sorting port changes to yellow state, and no more parts are unloaded from this sorting port, which is convenient for personnel to process each sorting port.
[0039] The high-voltage control cabinet converts the 380V industrial electricity into the electricity required by each unit, and realizes the start of the collection equipment from the operation panel or the host computer of the high-voltage unit.

The main control unit controls the running speed of the belt in the feeding section 1, controls the photographing time of the camera 6, integrates the data while conducting wired data communication with the host computer, and sends the data to each sorting unit through wireless communication. The sorting unit receives the trolley sorting information transmitted from the main control unit through wireless communication, controls the trolley to perform sorting actions at its corresponding sorting port 4, and records the sorting data and transmits the data back to the main control unit at a specific position on the main line to achieve information closed-loop. The sorting port processing unit displays the current state of the sorting port 4 through an indicator light. Green indicates the normal state of the sorting port 4, and the goods 8 can be sorted to this sorting port 4. Yellow indicates the bag full state, and the goods 8 will no longer be sorted to this sorting port 4. Red indicates the abnormal state of the sorting port 4, indicating that the operator presses the operation button or the host computer prohibits the goods 8 from being sorted to this sorting port 4;
[0040] The sorting control process is as follows:
[0041] 1. Power on the high-voltage control cabinet equipment, and the host computer starts the whole machine equipment through software;
[0042] 2. The main control unit detects the running speed of the main line section 2 through the main line photoelectric sensor 7, detects the belt speed of the feeding part through the feeding photoelectric sensor, and controls the servo motor of the feeding part to make the rotation speed of the feeding belt consistent with the running speed of the main line;
[0043] 3. Manually place the goods 8 face-up at the partition of the feeding belt by the operator;
[0044] 4. The main control unit detects the center hole spacing of the feeding belt through the center hole spacing photoelectric sensor of the feeding belt, thereby triggering the camera 6 to take pictures. The long goods detection photoelectric sensor 9 can be used to identify the long goods 8;
[0045] 5. The camera 6 performs recognition processing on the taken pictures, and transmits the information of the face sheet data with goods 8 and barcodes recognized to the host computer;
[0046] 6. The host computer integrates the data, and sends the sorting data of the trolley number corresponding to the goods 8 and the sorting port 4 number to which the goods 8 are to be sorted to the main control unit through the RS232 serial cable;
[0047] 7. The main control unit receives the sorting data sent by the host computer and sends it to each sorting unit through wireless 433 communication at a specific time interval;
[0048] 8. The sorting unit judges the sorting data sent by the main control unit to judge whether it is within the trolley range it controls. If so, it saves it; if not, it discards it;
[0049] 9. The sorting unit detects sorting port No. 4 through the ID detection sensor. If sorting port No. 4 matches the required sorting port No. 4 for the goods 8 on the vehicle, it controls the sorting control box of the current trolley to perform sorting actions and records the sorting action data of the trolley.
[0050] 10. After the sorting unit reaches a specific position, it transmits the sorting data to the main control unit via wireless 433 communication. The main control unit then transmits the sorting data to the host computer, and the host computer analyzes the data and displays whether the sorting is successful or a fault occurs.
[0051] 11. The main control unit periodically polls the sorting port processing unit to check the status of the sorting port sensor and button. According to the status of sorting port No. 4, the main control unit integrates and uploads the data to the host computer. The host computer can control whether the sorting unit continues to sort the goods 8 to sorting port No. 4 based on the actual situation analysis. The sorting port processing unit can display the current sorting status of sorting port No. 4 through an indicator light.
