概述
Summary
读入器负责与一组传感器通信，发射测温探询射频信号到传感器，接收温度传感器的返回信号，并解析成温度信息发送回温度监测主站软件系统。
The reader is responsible for communicating with a group of sensors. It transmits the radio frequency signal to the sensor, receives the return signal of the temperature sensor, and sends the temperature information back to the software system of the temperature monitoring master station.
产品外形及安装示意
Product Shape and Installation Indications
读取器天线通过与柜体的间隙穿过隔板吸附在柜壁。读入器放置在顶部，此柜门无需停电即可开启，方便管理人员进行操作。
The reader antenna is adsorbed on the cabinet wall through the gap between the reader antenna and the cabinet body through the partition board. The reader is placed on the top. The cabinet door can be opened without power failure, which is convenient for managers to operate.
工作原理
Working principle
读入器的天线嵌在开关柜内壁，这样以来可以屏蔽外部的电波干扰。而读入器的其他部分（接收箱）则安装在开关柜的外面。
The antenna of the reader is embedded in the inner wall of the switch cabinet so as to shield the external electromagnetic interference. The other parts of the reader (receiving box) are installed outside the switch cabinet.
读入器由单独的电源供电，并向开关柜内发射短射频信号。如果射频脉冲的频率与温度传感器预设的频率相同，传感器就能收到该射频信号，并且改变和被动地反射脉冲信号。返回的脉冲信号由于受到了传感器自身温度的影响因而携带了传感器的温度信息。
The reader is powered by a separate power supply and transmits short RF signals to the switch cabinet. If the frequency of the radio frequency pulse is the same as the preset frequency of the temperature sensor, the sensor can receive the radio frequency signal and change and passively reflect the pulse signal. The return pulse signal is affected by the temperature of the sensor itself, so it carries the temperature information of the sensor.
