Problems solved by technology

[0002] In the cross-board communication, the serial interface is the most commonly used and the earliest cross-board communication interface because of its few connecting lines and strong anti-interference ability. Of course, the serial interface also has a low transmission rate due to its earlier standards and fewer connecting lines.

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0028] like figure 1 As shown, in this specific embodiment, "one" of one-to-many serial communication is represented by a master control device (i.e. master), and "many" is represented by a slave device (i.e. slave); the TX (transmission data line...

Abstract

The invention provides a serial communication based one-to-many communication system and an implementation method. Main control equipment sends communication request command to a slave unit to which data is sent; the slave unit receives the data sending request command and returns communication response to the main control equipment; the main control equipment receives the communication response of the slave unit and then sends the sent data to the slave unit. The system solves the simple one-to-many communication mode of the traditional serial port, supports a one-to-many communication mode, and solves the problem that a host unit is communicated with a plurality of slave units without depending on hardware switching due to few ports of the host unit. The communication ports are reduced in resources, the port resources are saved, and the one-to-one end-to-end communication port is logically implemented.

Description

technical field [0001] The invention relates to a one-to-many communication system based on serial port communication and a realization method, in particular to a one-to-many communication system and realization method based on serial port communication suitable for cross-board communication. Background technique [0002] In the cross-board communication, the serial interface is the most commonly used and the earliest cross-board communication interface because of its few connecting lines and strong anti-interference ability. Of course, the serial interface also has a low transmission rate due to its earlier standards and fewer connecting lines. . There are many kinds of serial interfaces at present, and the RS232 serial interface is more commonly used; the RS232 serial interface (hereinafter referred to as the serial port) can usually only carry out one-to-one communication, that is, the software synchronous processing of sending and receiving to complete the communication ...
