摘　　要：针对物联网中传感器种类繁多、接口不一致的现状,设计了一种新型的无线传感器通用接口。该接口由信号处理电路、蓝牙芯片、电源和无线射频电路组成,具有体积小、即插即用、功耗低等特点。接口所采样的信号通过蓝牙传输给数据采集器或云服务器,并实时在界面上显示。该通用接口可在工业现场、智能家居、楼宇监控等场合下用于电流、电压、开关量与串口形式传感器信号的处理。并给出了通用接口的设计方案。测试结果表明,该接口可以有效处理传感器信号,达到了预期目标。To cover the wide range kinds of sensors and inconsistency interfaces, this paper presents a new universal wireless sensor interface. The interface with small size, plug and play, low power consumption, consists of a signal processing circuit, Bluetooth chip, power supply and radio frequency circuit. Signal sampled by this interface will be sent to the data collector or the cloud server through Bluetooth technology, and real-time displayed on the screen. The interface can be used in the industrial field, intelligent home, building control and other occasions for handling current, voltage, switch and serial sensor signals. The reference design is also given. Tests show that the interface can effectively deal with the sensor signal and achieve the expected target.
