Embedded linux-based method for realizing terminal maintenance and information release

Abstract

The present invention relates to an embedded linux-based method for realizing terminal maintenance and information release. According to the method, information interaction between an embedded web server and all functional modules of an electricity information collection terminal system is realized by using a common gateway interface (CGI) mechanism; and a client can visit an electricity information collection terminal service process by installing a web browser in a local computer, so that electricity information collection terminal maintenance and information release are realized. Without being limited by time and space, the user uses the WEB browser to visit, monitor and maintain a far end electricity information collection terminal through the Internet, specific software is not installed, and the method has the characteristic of cross-platform. An operator does not need to go to the site to operate, and the electricity information collection terminal maintenance is more conveniently, is real-time, and is efficient and safe.

Description

technical field [0001] The invention relates to the field of smart grid power consumption information collection systems, in particular to a method for realizing terminal maintenance and information release based on embedded linux. Background technique [0002] With the continuous development of Internet technology, in the management and interaction of embedded devices, the development and application based on embedded web server has become the mainstream. Generally, a B / S structure is adopted, that is, a web server is run on an embedded device, and the server needs to support script or CGI functions, and this structure is used to realize the generation of dynamic pages. Users only need to use a web browser on the client side to realize the management, monitoring and maintenance of embedded devices conveniently and quickly. [0003] The power consumption information collection terminal is a device for collecting power consumption information of each information collection p...

AI Technical Summary

Problems solved by technology

[0011] 1. The interactive message or log recording function requires the terminal to write the interactive message or system operation log between the terminal and other devices to the storage device in real time, resulting in too frequent operations on the storage device, which will seriously affect the service life of the storage device. It is very easy to cause the flash device where the file system is located to generate bad blocks;

[0012] 2. Use third-party software such as SSH, FTP, super terminal or special maintenance software to maintain the collection terminal. Most of them need to be installed. Generally, customers are prohibited from installing similar software on the main station side in consideration of system operation stability and security factors, such as If you need to use it, you must bring a notebook with corresponding software, network cables and other equipment to the site for operation. Many collection terminals are installed in remote locations, or even installed in high-level distribution boxes. On-site maintenance operations are very difficult. Collection terminals Close to high-voltage equipment, improper operation will affect personal safety;

[0013] 3. Real-time performance cannot be guaranteed

During the recording process of interactive messages or operation logs, in order to prevent the record file from being too large, it is necessary to periodically cut the file or limit the size of the message file. If the collected terminal message is not exported to the local for analysis in time, it may affect the The timeliness and integrity of the message;

[0014] 4. None of the above-mentioned existing maintenance methods can realize the maintenance of the acquisition terminal system from the hardware level, and do not have the functions of querying and configuring hardware registers, nor have the functions of checking and maintaining the underlying hardware drivers;

[0015] 5. The comprehensive maintenance of Linux system, application program, file system, and underlying drivers cannot be achieved simply through any of the above maintenance methods. It is necessary to combine the above maintenance methods and switch between different software to realize the maintenance of the acquisition terminal. Operation It is complex and limited by the software operating platform. Because the software needs to be installed, relevant maintenance operations must be performed on site;

[0016] 6. To maintain the on-site terminal with a handheld computer and a copy controller, it is necessary for the relevant manufacturer to develop a corresponding handheld software program. The direct contact of the copy controller with the power line will also affect equipment and personal safety, and on-site maintenance increases maintenance costs;

[0017] 7. Using SSH, FTP and other software to operate the collection terminal file system, it is very easy to modify the file name and file content of some files, resulting in data failure of important files, affecting the stability of system operation, and easily causing customer disputes
