Monitoring method and device of radiation system

Abstract

The invention discloses a monitor and control method of the heat-removal system and its device and realizes the speed control and speed detect to the fans in the heat-removal system of the communication facilities. The device includes a central control unit and the speed control device of the fans. The central control unit is integrated in the CPU of control panel of the communication facility. The steps of using the device to realize the invention include: the CPU outputs the speed control data of the fans; obtain the control signal to control the speed of the fans in according to the speed control data of the fans. Using the invention, we can make use of the programmable logic chip resource to realize the speed control and speed detect to the fans in the heat-removal system of the communication facilities, without increasing the cost of the hardwares, increase the work efficiency of the CPU and guarantee the safe operation of the communication facilities.

Description

technical field [0001] The invention relates to the communication field, in particular to a monitoring method and device for a cooling system. Background technique [0002] With the development of communication technology, a large number of circuits are integrated in communication equipment, and the energy consumption of equipment is also increasing. Therefore, heat dissipation plays an important role in ensuring the safe operation of communication equipment. Usually, there are various cooling systems, such as water cooling, semiconductor refrigeration, oil cooling, etc. But the most commonly used is relatively cheap air cooling, that is, cooling fans. At present, the intelligent management of communication equipment is becoming more and more important, and higher control and detection methods have been proposed for the heat dissipation system of communication equipment, and the implementation schemes are also diverse. In the prior art, it is necessary to separately design...

AI Technical Summary

Problems solved by technology

The disadvantage is that such a fan control board must be designed on the single board, which occupies more space on the equipment single board

If the single board uses a small CPU such as a single-chip microcomputer, its debugging means are lacking and the maintenance cost is high, because in the current communication equipment, the CPU mostly adopts a CPU with an embedded operating system with low debugging and maintenance costs

And if the CPU with embedded operating system is directly adopted in the fan control board, its hardware cost will be increased.

If the CPU of the system control board is used to detect the fan speed, it will occupy more CPU resources, reduce the working efficiency of the CPU, and easily affect the processing of other tasks by the CPU.
