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 operatin

Embodiment Construction

[0043] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] First refer to image 3 , image 3 It is a structural schematic diagram of the monitoring device of the cooling system according to the embodiment of the present invention. In the present invention, no separate fan control board is needed, and the control function is completed by the logic chip of the control board in the existing system equipment. The fan adopts PWM (pulse width modulation) to control the fan to enhance the flexibility of control. The principle of realizing the monitoring of the cooling system is as follows: Figure 4 shown. The central control device in the device of the present invention is integrated in the CPU of the communication equipment control board, that is, the control of the fan speed and the detection of the fan spee...

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...
