The Design Of High Precision Wireless Inclination Angle Sensor System

Along with the wireless sensor network technology, the mature wireless sensor technology got rapid development. Wireless sensor carrying, convenient installation, completely out of the traditional cable sensor faults, by wiring restrictions and wireless sensor simple maintenance, one time charge can use for a long time, can be widely used in defense military, environmental monitoring, traffic management, medical and health care and other fields, and has a very broad prospect of application.This paper first analyzes the principle of Angle measurement, this paper discusses the high-precision wireless Angle sensor system overall design scheme, on this basis, using wireless microcontroller as the system CC1110 wireless transmission with the core chip, SCA103T Angle sensor was designed D05 sensor node - the hardware circuit and completion of the dip Angle signal collection and transmission; MAX232 design with the data center node of the hardware circuit, complete with the sensor wireless communication function and superordination machine serial communication function.Secondly wireless sensor networks is studied, the relevant communication protocol for mini RF networks SimpliciTI low-power RF agreement as high-precision wireless sensor network protocol wireless communication protocol, according to system designed the agreement calls for a sensor node and data center node of the corresponding program. To realize the real-time monitoring of obliquity signal in Visual c + + 6.0 development environment of high precision wireless sensor system design of the PC software, PC software and data center through serial communication signals, realize the real-time monitoring of Angle.In the end the high-precision wireless Angle sensor had analyzed the error sources of several main error, and the corresponding compensation, improve the precision wireless Angle sensor system in the measurement accuracy.
