Data management method for electricity consumption information collection terminal

Abstract

The invention discloses a data management method for an electricity consumption information collection terminal. The method comprises the steps of analyzing all data of the electricity consumption information collection terminal to establish a template base; establishing a group of new databases, wherein the databases comprise three parts including a data set, a data structure and a data field; acquiring a command for operating the data of the electricity consumption information collection terminal; operating corresponding data of the established databases, updating the content of the databases in real time to complete data management. According to the method, the difficulty for development of an application program is reduced, the waste caused by different processes for memory use is decreased, the running efficiency of a system is improved, the problem of generation of deadlock is avoided, the later maintenance cost is reduced, the occupation for equipment memory is less, and the method is safe and reliable and efficient and stable.

Description

technical field [0001] The invention specifically relates to a data management method for a power consumption information collection terminal. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's daily production and life, bringing endless convenience to people's production and life. [0003] Many devices, including electric energy meters and electricity information collection terminals, will involve data storage, reading and writing and other management operations in their work, and such devices have very strict requirements on data reliability and accuracy. Require. Therefore, an efficient, safe and reliable data management method is extremely important for this type of equipment. [0004] At present, due to the strict limitation of the operating environment and hardware resources, the power consumption informa...

AI Technical Summary

Problems solved by technology

[0005] First, the business of electricity consumption information collection is relatively complicated, and it is necessary to design multiple processes to work together concurrently to handle various businesses. At the same time, related data must be processed and transferred between different processes, so the design of the program becomes more complex. complex

[0006] Second, there are many types of electricity consumption information data, which need to be stored in multiple files according to different types

However, the memory of the power consumption information collection terminal is very limited. If different processes open multiple identical files at the same time, the memory usage will be wasted.

[0007] The third is that different processes need to be protected by read-write locks to access the same file, and the CPU performance of the power consumption information collection terminal is very limited. Complex and disorderly resource competition is likely to cause system operating efficiency problems, and it is also prone to death. lock problem

[0008] Fourth, the electricity consumption information collection terminal generally lacks convenient remote debugging and analysis methods. When a problem is found on site, it can only be analyzed after the event by recording the operation log. If the log function is not enabled, the opportunity to analyze the problem will be missed.

[0009] Fifth, complex services such as electricity consumption information collection are troublesome to maintain with traditional software design

When the interface changes, the related programs and dynamic libraries must be recompiled and upgraded, resulting in an increase in maintenance costs
