Abstract  With the widely use of the sensor and the development of network techniques, Intelligent sensor system becomes a growing trend of sensor. According to the IEEE 1451.2 standard, an intelligent sensor system based on STM32F103 was designed, including an intelligent sensor module, a network adapter module, an upper computer and their corresponding running softwares. The intelligent sensor module used IIC to communicate with the network adapter module while the network adapter module used Wi-Fi to communicate with the upper computer and acted as the communication bridge between the intelligent sensor module and the upper computer. Experimental results showed that the intelligent sensor module could store the information of itself and the sensor, and realize the plug-and-play capability of the sensor. Besides, the network adapter module could make the intelligent sensor module achieve its plug-and-play capability. Moreover, the upper computer could realize instruction sending, result receiving and managing, as well as achieve real-time monitoring of the connection status between itself and the network adapter module. The intelligent sensor system realized wireless remote monitoring, getting rid of the shackles of cables, so it could adapt to more monitoring scenarios. It could read the information of the sensor itself, so as to identify the sensor and compatible with different types of sensors. It could also realize the self-calibration function of the sensor, so that the measurement results could be more accurate. The research results can provide reference for the development and application of large intelligent sensor system.
