Power distribution cabinet management system based on Internet

Abstract

The invention discloses a power distribution cabinet management system based on the Internet. The system comprises a signal sampling module and a feedback noise reduction module, the signal sampling module samples carrier signals of a signal emitter node in the power distribution cabinet management system based on the Internet. The signal sampling module is connected with the feedback noise reduction module; a triode Q1 is used for detecting a potential difference between a resonance circuit output signal and a triode Q3 emitter signal; the accuracy of the signal amplitude is further ensured;a triode Q2 is used for feeding back the potential difference between the output end and the in-phase input end of the operational amplifier AR2; when the difference value is too large, it representsthat the output signal of the operational amplifier AR2 is not within the error range, the signal is fed back to the inverting input end of the operational amplifier AR1, and the power distribution cabinet management system terminal based on the Internet can make a quick response to carrier signal distortion in time from new noise reduction and frequency stabilization adjustment to the time when the output signal of the operational amplifier AR2 is within the error range.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an Internet-based power distribution cabinet management system. Background technique [0002] At present, the rapid development of the Internet has prompted the gradual addition of domestic data centers. These devices have high automation, high efficiency, and long continuous operation time. The corresponding requirements for power supply are also very high, and the capacity of low-voltage distribution transformers is also increasing. The performance of low-voltage distribution cabinets is required to be higher and higher, which is the basis for adapting to the rapid development of today's information technology; [0003] The Internet-based power distribution cabinet management system can improve the management efficiency of the power distribution cabinet. However, the information transmission of the power distribution cabinet is mostly carrier transmission. Because of the l...

Problems solved by technology

[0003] The Internet-based power distribution cabinet management system can improve the management efficiency of the power distribution cabinet. However, the information transmission of the power distribution cabinet is mostly carrier transmission. Because of the long-distance transmission, it often encounters the same or high-frequency signal interference in the atmospheric environment, such as In power plants and signal towers, the carrier signal is often distorted, resulting in inaccurate reception of signals by the Internet-based power distribution cabinet management system, which reduces the use effect of the Internet-based power distribution cabinet management system
