Method and device for preventing condensation of PCB (printed circuit board) of UPS (uninterrupted power supply) or EPS (emergency power supply) host

Abstract

The invention relates to the technical field of protection for UPS (uninterrupted power supply) or EPS (emergency power supply) hosts, in particular to a method for preventing condensation of a PCB (printed circuit board) of a UPS or EPS host. The method includes steps of A, acquiring data of the temperature and the humidity of a position close to the PCB at least when the host is just started; and B, judging whether condensation of the PCB can occur or not according to the data, energizing the PCB if the condensation of the PCB cannot occur, and avoiding energizing the PCB and controlling the temperature and the humidity of the PCB if condensation of the PCB can occur. The method is implemented by constructing a functional module structure and controlling a computer system by instructions of computer programs. By the method, condensation on the PCB due to temperature rise when the UPS or EPS host and the PCB are started is prevented, and risk of short circuit of the PCB is further prevented. Besides, an integral case is not required to be detected, and temperature and humidity control for the integral case is omitted, so that energy is saved, and precise control is realized.

Description

technical field [0001] This application relates to the technical field of UPS (uninterruptible power supply) or EPS (emergency power supply) mainframe protection, in particular to a method for preventing condensation on the PCB board of UPS or EPS mainframe. The method is accomplished by establishing a functional module framework and controlling the computer system by computer program instructions. Background technique [0002] At present, the use environment of the PCB in the UPS or EPS host is not ideal, especially in areas affected by humid weather. The working environment of the PCB inside the host is affected by the temperature and humidity of the computer room. Exposure leads to a short circuit, making the UPS and EPS hosts unable to work normally, greatly reducing the reliability of the normal operation of the UPS and EPS host power systems, and causing great damage to the entire power system. [0003] In particular, when the UPS or EPS host is in a low-temperature e...

Problems solved by technology

[0004] In the existing technology, in order to prevent condensation, it is generally necessary to add large-scale temperature and humidity control equipment to the computer room, or monitor the temperature and humidity in the chassis and adjust the temperature and humidity to avoid condensation. Or the space of the chassis is relatively large and not sealed, and it takes a lot of energy to control the entire computer room or chassis; on the other hand, it is also difficult to ensure good temperature and humidity control for the space of the computer room or chassis. The board will not generate condensation due to improper space settings; and the most important thing is that this method cannot ensure that the PCB board will not cause condensation due to temperature rise when the host is first started, and then a short circuit will occur
