Power data processing method based on vxworks operating system

Abstract

The invention provides an electric power data processing method based on a VxWorks operation system. The electric power data processing method based on the VxWorks operation system is simple to operate, low in cost, high in degree of automation, and high in protection rate for illegal modification of programs. The electric power data processing method based on the VxWorks operation system is characterized by comprising the following steps of compressing relative programs in a storage chip, creating a certain redundancy space, compressing application programs for electric power data processing, backing up to a corresponding redundancy space, detecting the application programs for electric power data processing in the storage chip when a system is started every time after backup is completed, and replacing with a backup application program if program error is found.

Description

technical field [0001] The invention relates to the technical field of data processing of power data acquisition terminals, in particular to a power data processing method based on a VxWorks operating system. Background technique [0002] The VxWorks operating system is an embedded real-time operating system (RTOS) designed and developed by WindRiver Corporation of the United States in 1983, and it is a key component of the embedded development environment. Because of its good sustainable development capability, high-performance kernel and friendly user development environment, it occupies a place in the field of embedded real-time operating systems. With good reliability and excellent real-time performance, it is widely used in communications, military, aviation, aerospace and other high-tech and high-real-time demanding fields, such as satellite communications, military exercises, ballistic guidance, aircraft navigation etc. Power data acquisition terminals also generall...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages in actual use: this is a very traditional data and file storage mechanism, it simply collects and stores data, and the collected data files and important parameter files of the application program have been calibrated. Call directly after inspection, there is no corresponding automatic backup mechanism after use, and the size of the application file is equivalent to the size of the memory chip, there is no space on the memory chip for backing up data, if the user wants to back up important data, only an external storage device or increase the capacity of the storage chip on the hardware

If an external storage device is connected, manual backup is required, and the storage device and interface must be customized, which is costly; similarly, if the capacity of the storage chip in the system hardware is to be increased, such as a 16M flash chip used in the prior art, it is necessary to increase In terms of capacity, you need to change to a 32M flash chip, or set up two parallel 16M chips

However, the hardware of the control system is equipped at the factory, and the cost of the user's own modification is high, and there may be hardware incompatibility problems

To sum up, the power data processing method based on the VxWorks operating system in the prior art requires external equipment or modified hardware for backup and recovery, and its operation is cumbersome, high in cost, and low in automation

In practice, the power data acquisition application program based on the VxWorks operating system is often disturbed by clutter during system startup and operation, resulting in illegal modification of the application program. However, the above-mentioned method often has the problem of untimely backup and illegal modification of the program. The protection rate is not high
