In specific implementation, as shown in fig. 6, the working principle is as follows: the resistor R161 and the triode Q21 form an enabling circuit of the detection circuit, when the detection circuit needs to work, the SER _01 inputs high level, current passes through the resistor R161 to the base of the triode Q21 to enable the triode Q21 to be conducted, and the detection circuit is electrified to work. When the detection circuit is powered on, current flows through the current-limiting resistor R121 to the infrared transmitting tube D27, infrared light is emitted from the infrared transmitting tube D27, and the infrared receiving triode Q11 is arranged at the corresponding position. When materials exist in the warehouse, infrared light cannot reach the infrared receiving triode Q11 due to the shielding of the materials, the infrared triode Q11 is cut off, the collector of the infrared triode Q11 is high level, therefore, the triode Q1 is not driven by current to be cut off, no current is output from the feedback bus, the detection end connected with the MCU is connected with the pull-down resistor which is grounded, and the signal detected by the MCU is low level. When no material is in the warehouse location, the infrared light of the infrared transmitting tube D27 can be transmitted to the infrared receiving triode Q11, the infrared receiving triode Q11 is conducted, the collector of the infrared receiving triode Q11 is at a low level, the base of the triode Q1 is in current conduction due to the resistor R151, the triode Q1 is conducted, and the feedback bus outputs a high level.
The resistor R122 is a bias resistor, and can prevent the influence of ambient light on the infrared receiving transistor Q11. Resistor R123 is a bias resistor of transistor Q1 to prevent interference from causing abnormal conduction of transistor Q1.
When the detection circuit does not work, the SER _01 inputs low level, the triode Q21 is cut off, the detection circuit is forbidden, no current flows through the infrared transmitting tube D27 and the infrared receiving triode Q11, the triode Q1 is cut off, and the detection circuit does not output to the feedback bus.
Preferably, the clock of each shift register is connected to the IO port of the MCU, the data input end of the first shift register is also connected to the IO port of the MCU, and the input end of the next shift register in the two adjacent shift registers is connected to the last output end of the previous shift register in a one-to-one correspondence, so that the shift registers serially input and output data signals in parallel.
In specific implementation, a circuit diagram of three shift register cascades is shown in fig. 7, and it should be noted that the cascades of the shift registers are not limited to the three-stage cascades shown in the drawing, and the specific number of the cascades should be set according to actual requirements. The serial-parallel conversion circuit is formed by connecting a plurality of shift registers in series, the data input end of the first shift register is connected with the IO port of the MCU, the data input end of the second shift register is connected with the last data output end of the first shift register, and therefore the cascade connection is carried out, and the data input end of the shift register of the next stage is guaranteed to be connected with the last data output end of the shift register of the previous stage. And the data clocks of all the shift registers are connected to the IO ports of the MCU in a unified way. In addition, a plurality of data output ends of the shift register are connected to corresponding detection circuits to enable the drive, when the data output ends of the shift register output high levels, the detection circuits enable, and the detection circuits can normally detect whether materials are placed on the warehouse. When the data output end of the shift register outputs low level, the detection circuit is forbidden to work, and the output of the feedback bus is equivalent to high resistance state, so that the detection of other detection circuits is not influenced.
In summary, as shown in fig. 6 and 7, the material state detection process of the whole shelf storage location is as follows:
1. the MCU is connected with the DATA IO port of the first-stage shift register, the 164_ DATA is enabled to output low level, the MCU is connected with the IO ports of all the shift register DATA clocks, the 164_ CLK is enabled to send out pulses with corresponding number, the DATA output of the shift register is enabled to be completely initialized to be low level, and all the detection circuits are disabled.
2. When the detection is started, the MCU transmits a command to enable 164_ DATA to output a high level, 164_ CLK outputs a pulse, the DATA output interface QA of the first shift register outputs a high level, and the detection circuit at the first position is enabled.
3. Then, a feedback bus of the MCU is set as an input port, and a pull-down resistor is connected at the same time; when the first detection circuit detects that the material exists in the warehouse, the infrared transmitting tube D27 cannot reach the infrared receiving triode Q11, the output of the feedback bus is in a high-resistance state, and the pull-down resistor is grounded, so that the feedback bus is pulled down to be in a low level, and when the first detection circuit detects that the material does not exist in the warehouse, the feedback bus outputs a high level. Therefore, the MCU can identify whether the first storage position has the material or not through the high and low levels of the feedback bus. And recording the material state of the first storage position.

For example, three consecutive repetitions of the assay may be performed.
Preferably, in order to avoid the material getting in-process, infrared sensor's signal is disturbed repeatedly among the detection circuitry, and control module need remove through software shake or the mode that hardware removed the shake to the signal when gathering the signal and remove the processing to improve the accuracy that detects.
