Intelligent power supply and distribution monitoring apparatus

Abstract

The invention relates to an intelligent power supply and distribution monitoring apparatus. The apparatus comprises an upper computer module, a data acquisition and electric energy measuring module, a communication transmission module, a microcomputer protection module and an intelligent monitoring module, wherein the upper computer module takes an ARM as the core processor; the input end of the core processor is connected with a UPS power supply and a man-machine interface separately, while the output end of the core processor is connected with a data storage unit and a printer separately; data transmission between the data acquisition and electric energy measuring module and the upper computer module is carried out through a shielded twisted pair; data transmission between the communication transmission module and the upper computer module is carried out through a GPRS signal; data transmission between the microcomputer protection module and the upper computer module is carried out through an RS232 bus; and data transmission between the intelligent monitoring module and the upper computer module is carried out through an RS485 bus. The intelligent power supply and distribution monitoring apparatus has the characteristics of high reliability, high interference resistance, high real-time property, simple maintenance, and the like, so that the unattended operation of the power supply and distribution system, and more intelligent system can be realized.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution monitoring, and in particular relates to an intelligent power supply and distribution monitoring device. Background technique [0002] With the rapid development and wide application of industrial automation technology, the application of power distribution monitoring system in the field of industrial technology and service industry is increasing, and the scale of power supply and distribution is getting larger and larger. Improving management level and reducing maintenance and management workload have become There is an urgent need that distribution monitoring will be a key part of managing automation and the basis of smart grids. [0003] The current power supply and distribution monitoring system uses optical fiber, telephone dial-up, power distribution carrier and other communication methods. These communication methods have their own characteristics. Due to reasons such ...

AI Technical Summary

Problems solved by technology

[0003] The current power supply and distribution monitoring system uses optical fiber, telephone dial-up, power distribution carrier and other communication methods. These communication methods have their own characteristics. Due to reasons such as high construction costs, poor reliability, and high bit error rate, the power supply and distribution monitoring system is restricted. development of

[0004] In addition, the traditional power supply and distribution monitoring system has relatively simple equipment and control, and has a low degree of automation. It needs special personnel on duty and inspection, and cannot monitor the power consumption status and fault location of power equipment in real time. When a fault occurs, it needs to follow the line Find, lack of intelligent functions
