Computer room air conditioner protection protection shutdown self-diagnosis self-starting device

Abstract

The invention discloses a self-diagnosis and self-starting device for the protection and protection of an air-conditioner in a machine room, which is characterized in that it has an air-conditioning protection self-diagnosis and self-starting module connected to the main control board of the air conditioner, and the air-conditioning protection self-diagnosis and self-starting module described in the timing circuit Detect the compressor temperature sensor, discharge pressure sensor signal and compressor stop signal respectively. When the above signals appear at the same time, it means that the air conditioner is shut down due to high pressure protection, thereby triggering the timing circuit. When the time is up, the air conditioner protection self-diagnosis and self-starting module will restart. Detect the signals of the compressor temperature sensor and the exhaust pressure sensor, and if the signals return to normal, power off and reset the main control board, and start the air conditioner. It can automatically detect the shutdown status, and can automatically reset and start the machine. Resetting the air conditioner in time can ensure that the electronic components in the computer room do not overheat, and ensure the safe and stable operation of communication equipment.

Description

technical field [0001] The invention belongs to the technical field of air conditioner control, and in particular relates to a self-diagnosis and self-starting device for protection and shutdown of an air conditioner in a computer room. Background technique [0002] Power communication is a dedicated communication network supported by the main network of the power system. It is the basis for the safety and stability of the power grid, the control system and the dispatch automation system, and is an important prerequisite for realizing the modern management of the power system. Therefore, the requirements for real-time, accuracy and reliability of communication are very high. However, due to the particularity of communication electronic equipment components and the strict requirements on ambient temperature, it is necessary to maintain the stability of the air conditioning facilities in the computer room environment of communication electronic equipment. It is a favorable gua...

Problems solved by technology

[0003] In the high temperature weather every summer, the communication dispatching monitoring system will receive an alarm signal that the temperature of the communication room of the substation is too high. After this situation occurs, the on-duty personnel will notify the local on-duty personnel of the substation to check the reason in the communication room. More than 97% of them are due to the air conditioner. The external heat sink is blocked and the protection shut down caused by poor heat dissipation, thus causing the alarm of the high temperature of the communication room of the substation

The on-duty personnel of the substation resets the air conditioner and restarts it. In this way, the whole process from the alarm to find the problem, the notification to find the cause, and the reset of the air conditioner takes more than an hour, and sometimes it takes longer, which brings hidden dangers to the safe and stable operation of the equipment. Excessive burning of the board causes communication interruption
