The Constant Temperature Automatic Control System Design of 3G Base Station without Man´s Guard

The SCM of 89C52 is used to control the temperature of 3G base station, it can enhance the physics capability and technique guideline widely for its high dependability, simple structure, usage convenience etc. And it also can save electricity. Through the design of air condition automatic control system of some 3G base station, some relative design of software and hardware of intelligence temperature control are introduced. The design of constant temperature automatic control can be applied in unattended base stations widely. It can improve the communication system´s stability, reliability and quality. It also can be applied the place where needs temperature automatic control.
