The wireless monitoring system based on radio-frequency technique

According to the remoteness and dispersion of the monitoring points,the multiplicity of the monitoring objects,the application of the wireless monitoring system was limited.A solution based on radio-frequency technique was proposed in this paper.The design idea and implementation method of the system were described,the hardware design of the system node and the communication protocol were given.The proposed system adopted the ultra-low power consumption MCU MSP430 and single radio-frequency transceiver chip nRF905 as the system core,meanwhile,frequency hopping mechanisms were introduced in communication protocol to improve the noise immunity of the system.The experimental results show that the system has characteristics such as good real-time performance,high stability,low power consumption,strong practicality and good flexibility.The system can realize high precision monitoring of multiple signal.It has good popularization value application value in design of wireless monitoring system which has small data quantity to communication.
