面向工业传感器的多协议数据转换网关设计

针对RS485、CAN传感器数据传输方式单一的问题,设计了一种多协议数据转换网关。网关以STM32为核心,外围搭建多种通信接口电路,并建立数据缓存机制以实现RS485、CAN传感器与RS232、以太网、LoRa之间的数据传输。在RS485、CAN称重传感器与上位机的通信实验中,网关能及时准确地将传感器数据通过3种通信接口发送到上位机,验证了设计的可行性,解决了2类传感器数据传输渠道单一的问题。

Principle and realization method of tunnel deformation detection based on image recognition and data transmission technology

To detect the deformation of the tunnel structure based on image sensor networks is the advanced study and application of spatial sensor technology. For the vertical settlement of metro tunnel caused by internal and external stress after its long period operation, the overall scheme and measuring principle of tunnel deformation detection system is in- troduced. The image data acquisition and processing of detection target are achieved by the cooperative work of image sensor, ARM embedded system. RS485 communication achieves the data transmission between ARM memory and host computer. The database system in station platform analyses the detection data and obtains the deformation state of tunnel inner wall, which makes it possible to early-warn the tunnel deformation and take preventive measures in time.
