The appearance of networked sensors has met the demands in the increasingly large amount of information and high speed of measurement and control system. And networked sensors have already become a development trend of sensor technology.At first, the structure of the networked sensor is analysed. Based on an object-oriented technology and IEEE 1451 standard, a kind of information model for networked sensors is proposed in order to solve the interchangeability and interconnectivity between a sensor network and a sensor node.Then a CAN bus networked sensor is designed based on this model. The sensor designed uses a digital temperature sensor chip to measure temperature, adopts an independent CAN controller and a CAN bus driver as the physical layer and data link layer of the CAN communication specification. The CAN2.0A and CAN2.0B communications under both BasicCAN and PeliCAN modes are realized respectively. Also, a networked sensor based on Ethernet is designed according to the same model. The hardware taking a microprocessor and a network chip as the sensor core is developed. And an embedded TCP/IP including ICMP, ARP...
