Application Research Of Short-range Wireless Data Network

Short-range wireless data network with its dynamic ad hoc networks, data transmission reliability, network characteristics of large capacity is being applied to the wide fields of application.In this paper, sort out short-range wireless communication technology generation and development, begin to highlight short-range wireless data network, and refer to mature ZigBee communication protocol standards, develop our own wireless communication protocols. The purpose is based on self-development of wireless communication protocols for wireless data networking technology, applied research. Based on the analysis ward wireless intelligent monitoring system should have the function and composition of the framework, based on the application of wireless communication protocols based on self-development of the wireless data network technology of the system prototype development and production. In this paper, the overall grasp the wireless data network technologies, developing proprietary wireless communication protocol based on the solution of the ward Wireless Intelligent Monitoring System for key technical problems.Based on Taiwan's macro Crystal Technology, Inc. STC89C516RD+ micro-controller and Nordic companies NRF24L01 RF communications chips to complete ward wireless intelligent monitoring system for monitoring node and the network coordinator node hardware development.In this paper, refer to ZigBee protocol standard, based on our own design of a wireless communication protocol architecture and protocol development based on the temperature acquisition program, wireless data transmission program, serial communication program, display alarm program, key scanner to achieve an agreement based on the software development. In this paper, the node of their own design and coordination of hardware and software platform device, according to Ward wireless intelligent monitoring system functions and architecture requirements, implementation based on short-range wireless data network technology and self-development of communication protocol standards for the star topology networking to complete the in the node and coordinator between the effective and reliable two-way data transmission.
