Two output pins are set on the power supply device 3, namely Vout+ and Vout-, wherein Vout+ is connected to the pad hole V+ of the main control device 4 and the + lead of the detection device 5, and Vout- is connected to the pad hole V- of the main control device 4 and the - lead of the detection device 5. The power supply device 3 provides power to the detection device 5 and the main control device 4.

[0038] The main control device 4 is a square electronic circuit assembly board with a size of 50mmX50mm. Four through holes are arranged on the four corners. The diameter of the through holes is 3mm. The distance between two adjacent through holes is 40mm. The positions of the through holes are aligned with the positions of the four high studs in the lower shell 1.

[0039] See also Figure 3 The main control device 4 includes MCU U1, LDO U2, optical coupler U3, relay K1, buzzer B1, transistor Q1, transistor Q2, resistor R2, resistor R3, resistor R4, resistor R5, resistor R6, resistor R7, and resistor R8.

[0040] The model of the LDO U2 is LM7805, with an output voltage of 5V and a current of up to 1A. The VCC pin of the LDO U2 is connected to the pad hole V+ (i.e., the Vout+ pin of the power supply device 3), and the VSS pin of the LDO U2 is connected to the pad hole V- (i.e., the Vout- pin of the power supply device 3). The 12V output by the power supply device 3 is stepped down to 5V and output at the VO pin to provide working voltage for the MCU U1, the buzzer B1 and the relay K1. The output end VO pin of the LDO U2 is connected to the VCC pin of the MCU U1, the 2 pin of the relay K1, the positive pole of the buzzer B1, the resistor R3, the resistor R4, the resistor R6, and one pin of the resistor R8.

[0041] The model of the optical coupler U3 is PC817, pin 1 of the optical coupler U3 is connected to one pin of the resistor R7, the other pin of the resistor R7 is connected to the pad hole IN (i.e., the OUT lead of the detection device 5), pin 2 of the optical coupler U3 is connected to the pad hole V- (i.e., the Vout-pin of the power supply device 3), pin 3 of the optical coupler U3 is connected to the pad hole V- (i.e., the Vout-pin of the power supply device 3), pin 4 of the optical coupler U3 is connected to the IN3 pin of the MCU U1 and one pin of the resistor R8, and the other pin of the resistor R8 is connected to the VO pin of the LDO U2.

[0042] Working principle: When the pad hole IN inputs a high level, the optocoupler U3 is turned on, and its 4 pin is at a low level at this time. Conversely, when the pad hole IN inputs a low level, the optocoupler U3 is turned off, and its 4 pin is at a high level at this time.

[0043] The model of the relay K1 is HF46F-05-HSI, the working voltage is 5V, and the rated working current can reach 10A. Pin 1 of the relay K1 is connected to the C pin of the transistor Q1, and is also connected to one pin of the resistor R3. The other pin of the resistor R3 is connected to the VO pin of the LDO U2.

[0045] Working principle: When the OUT1 pin of MCU U1 outputs a high level, the transistor Q1 is turned on, the relay K1 is energized, and its pins 3 and 4 are connected. Because the pad hole CO1 is connected to the live wire L1, the pad hole CO2 is also connected to the live wire L1 at this time, so that the pin 1 of the switch device 6 is connected to the live wire L1, and the switch device 6 is energized. Conversely, when the OUT1 pin of MCU U1 outputs a low level, the transistor Q1 is turned off, the pins 3 and 4 of the relay K1 are separated, the pad hole CO2 is disconnected from the live wire L1, and the pins 3 and 4, pins 5 and 6, pins 7 and 8, and pins 9 and 10 of the switch device 6 are separated.

[0046] The transistor Q2 is of model s8050, NPN type, and has an operating current of up to 500mA. The B pin of the transistor Q1 is connected to one pin of the resistor R5, the other pin of the resistor R5 is connected to the OUT2 pin of the MCU U1, the E pin of the transistor Q2 is connected to the pad hole V- (i.e., the Vout- pin of the power supply device 3), and the C pin of the transistor Q2 is connected to the negative pole of the buzzer B1.

[0048] Working principle: When the OUT2 pin of MCU U1 outputs a high level, the transistor Q2 is turned on, the C pin of the transistor Q2 becomes a low level, and the buzzer is turned on and beeps; conversely, when the OUT2 pin of MCU U1 outputs a low level, the transistor Q2 is turned off, the C pin of the transistor Q2 becomes a high level, and the buzzer stops beeping.

[0049] The model of the MCU U1 is STC8A8K32AS4A12, with high operating frequency and low price. The IN3 pin of the MCU U1 is connected to one pin of the resistor R8 and the 4 pins of the optocoupler U3, the other pin of the resistor R8 is connected to the VO pin of the LDO U2, the VCC pin of the MCU U1 is connected to the VO pin of the LDO U2, the VSS pin of the MCU U1 is connected to the pad hole V- (i.e., the Vout- pin of the power supply device 3), the OUT1 pin of the MCU U1 is connected to one pin of the resistor R2, the other pin of the resistor R2 is connected to the B pin of the transistor Q1, the IN4 pin of the MCU U1 is connected to the pad hole FB (i.e., a pin of the AC contactor auxiliary switch) and one pin of the resistor R4, the other pin of the resistor R4 is connected to the VO pin of the LDO U2, the OUT2 pin of the MCU U1 is connected to one pin of the resistor R5, and the other pin of the resistor R5 is connected to the B pin of the transistor Q2.

[0050] See also Figure 4,MCU U1's IN3 pin detects a high level three times in a row, and it is considered that there is material to be transported. When the IN4 pin detects a low level, it is considered that the switch device 6 is in the energized state at this time, and the switch device 6 does not need to be operated at this time. When the IN4 pin detects a high level, it is considered that the switch device 6 is in the separated state, and the MCU U1 outputs a high level on the OUT1 pin to make the relay K1 energized, thereby making the switch device 6 energized and running the conveyor. At this time, the level state of the IN4 pin is detected again. If it is a low level, the switch device 6 operates normally. If it is a high level, the switch device 6 is out of control. At this time, the MCU U1 needs to set the OUT2 pin to a high level to make the buzzer B1 alarm and wait for maintenance. If the IN3 pin of the MCU U1 detects a low level in three consecutive detections, it is considered that no material is detected, and the OUT1 pin is set to a low level to make the relay K1 in the separated state and stop the conveyor.

[0053] See also Figure 7 The upper shell 2 is a square shell member with an open lower end, and its upper wall size is 162mmX162mm. The size between the inner walls of the open hole of the upper shell 2 is equal to the size between the outer walls of the open hole of the lower shell 1. The upper shell 2 and the lower shell 1 are slidingly matched, and a through hole with the same structure is respectively provided at the left and right ends of the front wall and the rear wall.

The upper shell 2 is buckled on the lower shell 1 and fixedly connected with screws.

[0055] Working principle of conveyor intelligent controller: When in use, fix the conveyor intelligent controller near the material hopper of the conveyor, and use wires to connect the 4, 6, and 8 pins of its switch device 6 to the A, B, and C terminals of the original motor of the conveyor to control the operation and stop of the conveyor, and make the detection light of the detection device 5 enter the material hopper. When material is poured into the material hopper, a material wall will be formed to reflect the detection light back to the detection device 5. The OUT lead of the detection device 5 is at a low level at this time, and the pad hole IN of the main control device 4 is at a high level. The MCU U1 in the main control device 4 detects that its IN3 pin is at a high level for three consecutive times, and then detects whether the IN4 pin is at a low level to determine whether the switch device 6 is closed. If it is at a low level, the switch device has been closed, that is, the conveyor is already in operation. If it is at a high level, it is necessary to set the OUT1 pin to a high level to close the switch device 6 and start the conveyor running. When no material is poured into the material hopper or mosquitoes fly over the detection distance of the detection device 5, the main control device 4 will detect a low level or cannot detect a high level for three consecutive times, then the OUT1 pin will output a low level to separate the switch device 6 and stop the operation of the conveyor. In order to confirm whether the switch device 6 is really separated, the auxiliary switch is detected again, that is, whether the IN4 pin is high. If it is high, the working state of the switch device 6 is fine. Otherwise, the buzzer is controlled to alarm and wait for maintenance.
