Abstract
Intelligent heat exchanger control system is adhere to the reality of base station construction. It is applied to environmental monitoring of communication base stations of China Mobile and China Unicom, substantially saves the energy, improves air quality in the shelter, which lays a solid foundation for promoting the entire quality of environmental monitoring of hermetic space base stations. Based on the developing orientation of contemporary mechanical and electrical products, the intelligent heat exchanger control system makes an improvement on cooling system, integral controlling, makes itself more intelligent, higher reliable, and better meet the need of market.
The design is on a part of entire intelligent heat exchanger control system- the upper computer design, aiming to realize the communication between the upper copmputer and lower computer of the intelligent heat exchanger control system. The upper computer’s polling monitoring on the lowercomputer guarantees the reliability of unattended sattion. focusing on the communication between the upper computer and the lower compuer, this article introduces entire design of the system, the formulating of communication programme and communication protocol, signal processing after reception, choosing Delphi controls, design of human-machine interface and realizable functions.
Keywords:Delphi, upper computer, serial communication
