Abstract
In order to improve the reliability of communication of the equipment in special narrow space, a kind of short—range wireless data communication system based on Nrf905 has been developed. The basic node of the system consists of Nrf905, STC series SCM, DS1302 and so on. A clock synchronization time dispatch table is designed which contains separate time windows and competition time windows. Individual nodes have two transmitting modes according to the time dispatch table which are time —sharing sending and partly competition sending. For multiple nodes of competition in competition time windows, a random number wince algorithm and frame interval priority method are used to reduce the probability of node collision. The results show that the system has high data transfer efficiency, high real time and high extensibility, and it can be widely used in a variety of short—range wireless data communication.关键词
