Embodiment 1

[0019] Embodiment 1 discloses a message cooperative normalization processing method based on the multi-source control application layer of the Linux system. According to the threads and semaphores provided by the Linux system, communication between threads and resource access are realized. All "communication sources" and The processing and analysis share the same semaphore, so as to realize the embodiment of the same analysis and processing function to complete the corresponding normalization processing, including the following steps:

[0020] S1. After the Linux system starts, the application program starts to start, and completes the two-dimensional data buffer pool Buff for the "control source" data of multiple communication interfaces 1 ~ Buff n The initialization of the flag Fn and processing is 0. Among them, n is a positive integer, and its size is equal to the number of external communication interfaces. There is no special explanation for the subscript n in the foll...

Abstract

The invention discloses a message collaborative normalization processing method based on a multi-source control application layer of a Linux system, and the method comprises the steps: achieving a one-to-one mapping relation between a communication interface and a thread according to the thread and semaphore provided by the Linux system, completing the receiving processing through an independent thread, and building a processing response bridge through the semaphore; according to the method, data receiving, content analysis and corresponding processing links of a communication source are effectively isolated from one another, when data of various communication interfaces are abnormal, positions can be conveniently and rapidly locked, problem reasons can be conveniently and rapidly found out, the research and development period of products is shortened, and the design efficiency, robustness and reliability of the products are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of embedded operating systems, and relates to a message cooperative normalization processing method based on a Linux system multi-source control application layer. Background technique [0002] Generally, embedded devices are convenient for external control, and use a variety of commonly used communication interfaces, such as network ports, parallel ports, and serial ports. In order to provide a rich control interface, the actual embedded device uses a variety of communication interfaces to control it. It is a typical device with multiple control sources, that is, there are multiple "control sources" (referred to as: multi-source control). When the equipment is designed, the same or similar protocol is adopted to optimize the redundancy of the equipment control protocol and realize efficient protocol multiplexing. The network port is transmitted in the form of Ethernet frames, and the serial port is trans...
