Abstract:In order to meet the long-distance、low cost、deployment flexible 、easy maintenance requirements for wireless information collection system,a long-distance information collection system having Wireless transmission and reliable IAP upgrading is designed and implemented. The system can automatically complete the target nodes signal acquisition and IAP wireless upgrade as long as the nodes are in the range of wireless signal. The design of hardware and software of nodes is described,IAP upgrades,collision avoidance mechanism. After testing,under the conditions of the wireless transmission rate 200bps effective communication radius is 500 meters,and the BRE of data packet forwarding is 2/10000.
