Embodiment Construction

[0035] The heat exchange monitoring device of the present invention realizes the following functions: 1) collect the temperature value; 2) calculate the temperature value and adjust the speed of the fan; 3) collect the speed state of the fan; 4) communicate with the external control device through the serial port and report The current temperature value and the fan speed, and can control the fan speed according to the command of the external control device.

[0036] The heat exchange monitoring device according to an embodiment of the present invention is composed of the following parts: a heat exchange monitoring unit, a fan, a temperature sensor, and an external control device. The heat exchange monitoring unit receives the temperature value sent by the temperature sensor, controls the rotation speed of the fan, and receives the rotation speed signal output by the fan. The heat exchange monitoring unit and the external control device are connected through a serial port.

Abstract

A method for intelligent monitor of heat exchange system includes such steps as acquiring the temp value of heat exchange system by the heat exchange monitor unit, calculating, and controlling the rotation speed of fan according to calculated result and fuzzy control table. Its device is composed of heat exchange monitor unit, heat-dissipating fan, and temp sensor. Its advantages are high intelligence level, low noise and power consumption, and long service life of fan.

Description

Technical field: [0001] The invention relates to a method and device for intelligent monitoring of a heat exchange system, in particular to a method and device that can control the speed of the cooling fan according to the actual ambient temperature and heat dissipation conditions, so that the exhaust air volume in the chassis can be adjusted; at the same time, the heat dissipation can be reduced. The noise of the fan saves energy; it belongs to the technical field of control or regulation. Background technique: [0002] The heat generated in the communication equipment rack is large. If the heat in the rack cannot be dissipated in time, the accumulated heat will cause the various components and devices in the equipment to fail to work due to continuous heating; malfunction or damage. In order to ensure the normal operation of the equipment, it is necessary to adopt the means of heat exchange, that is, to use the fan to dissipate the heat as soon as possible through the air...
