Power supply safety monitoring system

Abstract

The invention discloses a power supply safety monitoring system, which comprises a PLC, a voltage sampling board, a current sampling board, a high-frequency rectification module and a touch screen. The present invention fully utilizes various intelligent functions of the s7-200plc by using the Siemens s7-200, and realizes intelligent management and abundant man-machine interfaces. The monitor can directly send the control quantity to the rectifier module, which reduces the intermediate adjustment and conversion links, and can complete the real-time monitoring of the rectifier module more quickly, accurately and reliably. The monitor has strong functions, high reliability, less maintenance, and is easy to operate. At the same time, it can be easily connected to the integrated automation system through communication. It can provide safe, stable and reliable DC power for the integrated electric power automation system, and has a significant social and economic benefit.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a power supply safety monitoring system. Background technique [0002] At present, the DC power supply monitoring system for electric power has been widely used in my country's urban public power transformation and power supply, industrial and mining enterprises, high-rise buildings, and power supply and distribution in residential quarters. However, the general DC power supply monitoring system for electric power is only suitable for the monitoring of the DC power supply and the AC power supply in the integrated power supply, and cannot meet the needs of other power supplies in the integrated power supply. Most of the original monitoring system uses electric parameter transmitters and analog acquisition modules for measurement. Because of the large number of transmitters, the wiring is complicated and debugging is difficult. Because the line transmission is analog signals, it is easy to be...

Problems solved by technology

However, the general DC power supply monitoring system for electric power is only suitable for the monitoring of the DC power supply and AC power supply in this integrated power supply, and cannot meet the needs of other power supplies in the integrated power supply.

Most of the original monitoring system uses electric parameter transmitters and analog acquisition modules for measurement. Because of the large number of transmitters, the wiring is complicated and debugging is difficult. Because the line transmission is analog signals, it is easy to be interfered, so Generally only used in smaller DC power supply systems

[0003] In summary, the existing monitoring system for power supply equipment obviously has inconvenience and defects in actual use, and it cannot meet the needs of the development of integrated power supply and smart grid, so it must be updated
