Unmanned substation remote temperature monitoring system

Abstract

The invention discloses an unmanned substation remote temperature monitoring system which comprises an air conditioner host machine, an air conditioner controller, a temperature sensor, a terminal computer and a central server; the temperature sensor is arranged at a to-be-monitored place of an unmanned substation and is connected with the terminal computer for collecting the environment temperature information and feeds the environment temperature information back to the terminal computer; the terminal computer is respectively connected with the central server and the air conditioner controller, sends a control command to the air conditioner controller according to the environment temperature information, and sends the environment temperature information to the center server in real time; and the central server comprises a record storage module for storing the environment temperature information. Compared with the remote control adopting a 2G or 3G network in the prior art, the accuracy and the stability are improved greatly.

Description

technical field [0001] The invention relates to a remote temperature monitoring system, in particular to an unattended substation remote temperature monitoring system. Background technique [0002] In recent years, the expansion and expansion of the power grid has gradually attracted attention to the security application of substations. Every year, the National Development and Reform Commission will submit a certain number of substation construction or expansion projects for approval. At the same time, with the promotion of the unattended substation mode, in addition to meeting the needs of daily safety maintenance, the unattended substation also needs to monitor and control the temperature of the unattended substation during normal operation, otherwise it may be due to If the temperature is too high, the equipment will be damaged or a safety accident will occur. The temperature control method currently used is usually to increase the air conditioner to control the indoor t...

AI Technical Summary

Problems solved by technology

In the prior art, the remote control of the air conditioner operation of the unattended substation through the mobile Internet, although it can operate in theory, but because of the special electromagnetic field environment of the substation, it will inevitably cause great interference to the 2G network or 3G network, so in When using mobile Internet to manage or operate remote unattended substations, its accuracy and stability will be a big problem

For example, if the set temperature of the air conditioner is too low, many substations will cause a lot of waste of power resources; and if the set temperature of the air conditioner is too high or the feedback data is not accurate enough, it may cause serious accidents or economic losses

[0004] In addition, the remote control and management of air conditioners in the prior art can only reflect the working temperature of the unattended substation and the operation of the air conditioner through the text data transmitted remotely.

However, the text data information may deviate during the transmission process or the generation process, which is very likely to cause the remote manager to make a completely wrong action instruction based on this, which will inevitably cause undue equipment damage. or security incident

In other words, the existing air-conditioning remote management technical solution is not suitable for remote temperature monitoring and management of unattended substations, lacks fault tolerance, and needs to be improved
