Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, a specific embodiment of the present invention is a multi-channel control system for a self-service vending machine, comprising an MCU, a communication module, a display screen, a channel and a power supply, wherein the MCU is electrically connected to the communication module through a UART interface, the communication module and the MCU are also electrically connected to the power supply, the display screen is electrically connected to the MCU through an SPI interface, and the communication module is communicatively connected to a cloud server;

and a serial port converter is also arranged between the driving module and the MCU, and the driving module is electrically connected with the MCU through the serial port converter in a plate-order cascade mode respectively. The serial port converter is also internally provided with a single chip microcomputer, the MCU is provided with one or more serial port converters, each serial port converter can be connected with two serial port converters, and the serial port converters can be connected with and control 128 driving modules at most in a seven-stage plate cascade mode.
