The Design of the Clusters Real-Time Positioning System Based on RSSI

Abstract:

With the rapid development of wireless communication and wireless sensor network, there are a large number of application requirements of indoor positioning service, so it is very significant to the study of indoor positioning technology. The paper studied the indoor real-time location technology of ZigBee and designed the real-time positioning system, which included gateway, reference node, and blind node, monitoring software of computer and RSSI location algorithm. STM32 was used to control the gateway, which was integrated with ZigBee module and WiFi module. Reference node and blind node were communicated through CC2530.Monitoring system calculated the blind nodes’ coordinate based on the improved three edge location algorithm. Using computer simulate it, the results show that this method has low consumption, the characteristics of high precision, and has certain practical value.
