摘　　要：针对设备性能检测装置的检测结果受环境温度因素影响较大，为了保证该检测装置的环境温度处于某一恒温状态，设计了一种基于DSP控制的半导体制冷恒温控制系统设计方案。该系统采用DSP微处理器系统实时采集箱内温度，并与设定温度范围进行比较，结合温度变化阈值采用全功率制冷、降速制冷和恒温控制的策略切换，使箱内温度恒定在温度预定值，达到恒温状态。For a performance test equipment influenced by ambient temperature, the semiconductor cooling constant temperature control system is design based on DSP control in order to insure the enviormeut temperatune of the test equipment at the certain consaut temperature status. The system applies DSP microprocessor system to real -time collect the inside temperature of tank and compares with the temperature change threshold to switch the modes among the power refrigeration and speed reduction refrigerution and constant temperature control, so that the inside temperature of tank constant at a predetermined temperature value to achieve a constant temperature.
