Problems solved by technology

[0006] However, for micro base stations or distributed base stations, the above two methods have their unsatisfactory places
Because the volume of the fan using the first method is relatively large, and the micro base station or distributed base station itself is a box-type device, the internal space is relatively small, and it cannot accommodate the fan with the PWM speed control function, and such The interface of the fan and the algorithm of fan speed control are also complicated
If the second method is used, due to the enhanced functions of the new base station, the thermal power consumption of the whole machine is relatively large, and it is difficult to directly use heat pipes and heat sinks for heat dissipation to ensure that the base station can operate normally at an ambient temperature of 55 degrees Celsius. , using this method, the software can only passively do some post-processing according to the temperature of the base station, which is not flexible enough

Embodiment Construction

[0042] The present invention proposes a base station temperature control method, and when the present invention is used to control the temperature of micro base stations or distributed base stations, it can effectively overcome the shortcomings of the prior art. The main realization principle and specific implementation manners of the present invention will be described in detail below with reference to each accompanying drawing.

[0043] In the present invention, the temperature of the base station is controlled by a single fan, which does not have a PWM speed control function, and can only be controlled to be turned on and off. A single single fan cannot achieve the predetermined effect, and multiple single fans are used in the invention to jointly complete the temperature control of the base station. However, if a simple unified control is adopted for all fans, either all of them are running or all are still, all fans will continue to run most of the time, and their lifespa...

Abstract

The disclosed BS temperature control system as well as method to heat dispersion problem in minisize BS or distributed BS arranges a fan assembly with at least two mono-body fans to obtain some representative synthesis states according to every fan open and close states, and uses state machine principle to control fan, wherein when switching fan state, setting temperature difference to avoid frequent switch, and adding time factor when switching two fans with same heat dispersion state to average every fan work time and prolong whole fan assembly service time indirectly. This invention can achieve up to well heat dispersion effect, and compensates well the defect in prior art.

Description

technical field [0001] The invention relates to wireless base station technology, in particular to a method and system for temperature control of a base station. Background technique [0002] For micro base stations or distributed base stations, most of them operate in an outdoor environment, and the operating environment is relatively harsh. For this type of base station, it is generally required to be relatively small in size, because the base station itself will generate a certain amount of heat during operation, and the temperature of the base station will also be affected by the external temperature. If the external environment temperature is very high, plus the base station itself The heat generated by the operation will cause the temperature of the base station to be too high, which will affect the operation performance of the base station. In this case, we need to perform necessary heat dissipation treatment on the base station. There is no need for thermal treatmen...
