eps power supply system based on dual processors and its control method

Abstract

The invention provides an EPS power system based on dual processors. The EPS power system based on the dual processors comprises an input switch, an output switch, a charger, a storage battery pack, a storage battery pack monitoring module, an inverter, a bypass static switch, an inverting static switch and the DSP and further comprises a signal sampling and conditioning module and a monitoring module, wherein the monitoring module comprises the Loongson processor, a wireless communication module and a human-computer interaction module, the signal sampling and conditioning module is used for acquiring and processing measurement parameters and sending the parameters to the DSP, the storage battery pack monitoring module is used for monitoring the operating state of the storage battery pack and sending monitored parameters to the DSP, the DSP sends the measurement parameters and the monitored parameters to the Loongson processor, and the Loongson processor displays the measurement parameters and the monitored parameters through the human-computer interaction module and sends the measurement parameters and the monitored parameters to a remote terminal through the wireless communication module. Human-computer interaction and network monitoring of the EPS power system are established through the Loongson processor made in China, various kinds of information is acquired, displayed, stored and monitored when the system operates, it is guaranteed that all the parts of the system work orderly, and reliability of the system can be tested conveniently.

Description

technical field [0001] The invention relates to the field of EPS emergency power supply, in particular to a dual-processor-based EPS power supply system and a control method thereof. Background technique [0002] EPS emergency power supply (Emergency Power Supply: emergency power supply), as a backup power supply independent of the grid, is the most effective way to solve problems such as power outages and unstable power quality. When an accident occurs, it can ensure the provision of the required emergency power to effectively reduce the losses caused by power outages and ensure the safety of people's production and life. [0003] The principle of EPS emergency power supply is: when the power grid is normal, the mains power supplies power to the load equipment through the output switching device, and the charger charges or floats the battery at the same time; when the power grid is cut off or the voltage exceeds the power supply range, the processor starts the inverter At ...

AI Technical Summary

Problems solved by technology

Due to the poor specific environment for the installation and application of the existing EPS, it is difficult to monitor its operation. Usually, it is carried out through manual regular inspections. However, this monitoring method has certain limitations in terms of real-time performance and reliability. The problem
