| 摘 要： | ＲＷ２２型空调软卧车的空气调节系统原是固定逻辑式接触器继电器控制系统，该系统可靠性差，占的空间体积大，易损坏，常因故障而停机，因此，不能满足人们对软卧车舒适性的要求，为提高软卧车空调系统的可靠性，减少故障率，采用可编程序控制器代替原控制系统中的继电器部分。文章分析了原系统控制要求，论述了用ＰＣ实现的控制过程及电气控制保护。

| Abstract: | The old air conditioning control system for the RW 22 type soft berths railway carriages uses fixed logical contact agent relays.Such a system is poor in reliability and large in volume. It can be damaged easily, and often stops working.In order to improve the reliability and the control accuracy of the air conditioning system,the relays of the original system are replaced with the programmable controller.Based on analyzing the control demands of the original system,the control process with programmable controller and the electric control protection are discussed. |
