Overhead line data acquisition terminal power supply management system and method

Abstract

The invention provides an overhead line data acquisition terminal power supply management system and method. The system comprises a power supply module, a CPU management module, an output control module and a communication module. The power supply output end of each power supply line of the power supply module is connected with the power supply input end of the output control module. The power supply output end of each power supply line is also connected with the corresponding power supply voltage signal acquisition input end of the CPU management module in a one-to-one correspondence way through the corresponding power supply signal acquisition device. The power supply output control signal output end of the CPU management module is connected with the control signal input end of the output control module. The power supply output end of the output control module is used for being connected with the power supply input end of the overhead line data acquisition terminal. The communicationport of the CPU management module is correspondingly connected with the communication port of the communication module. According to the system and the method, the more stable power supply can be provided for the overhead line data acquisition terminal so that the maintenance probability can be reduced and the maintenance frequency of the work personnel can be reduced.

Description

technical field [0001] The invention relates to the technical field of power management, in particular to a power management system and method for an overhead line data collection terminal. Background technique [0002] In long-term engineering practice, the key to the success or failure of a hardware system lies in whether the power management is good enough. About 70% of the problems in the general system are concentrated in the power management circuit, and about 30% of other problems, especially for data acquisition terminals that have been used for a long time in the field, the failure rate caused by power supply problems accounts for more than 90%. [0003] The overhead line data acquisition terminal is set up to work in the field, and is designed to use multiple methods of power supply. It is required that the power system has high reliability, stable energy, stable voltage supply, and minimize shock waves. This requires a reliable power management system. system to ...
