Detailed Description

Example (b):

the embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all embodiments of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The expansion board is applied to the expansion and comprehensive control of automatic control equipment, and is used for the expansion control of the automatic vending machine, referring to an application shown in the attached figure 1. In an embodiment shown in the accompanying drawings, the expansion board is applied to expansion of an existing vending machine, in this embodiment, the main processing module adopts an STM32 embedded microcontroller with a high integration level as a main control, and has the characteristics of high performance, real-time performance, digital signal processing, low power consumption, high integration level and simplicity in development, and a circuit diagram of the main processing module of this embodiment is shown in the accompanying drawings. The serial port module of this embodiment adopts a 485 communication module, as shown in the drawing, and includes a J12 port, and is connected to the interface of the original vending machine through the J12 port to expand the signal.
