Embodiment Construction

[0054] The system of the present invention includes six parts: RFID sensing node, mobile reader, wireless sensor network gateway, mobile terminal equipment, system software and terminal software:

[0055] 1. The function of the RFID sensor node is to collect information at a fixed location, and send the data to the gateway device through the wireless sensor network through the wireless communication module. Each node consists of six parts: micro control unit, sensing unit, radio frequency unit, communication unit, positioning unit and power supply unit. . The nodes are arranged in a self-organizing wireless sensor network, operate autonomously, and transmit data to the background server through the network. All smart nodes are isomorphic, so simple and efficient data compression methods can be used. Finally, a flexible transmission protocol is necessary, and the best and most commonly used one is the ZigBee protocol.

[0056] 2. The mobile reader can have the mobile PDA car...

Abstract

The invention relates to a method for realizing an intelligent residential district system on the basis of RFID (radio frequency identification) in a wireless sensor network, which is characterized in that the system is formed by an RFID sensor node, a mobile reader, a wireless sensor network gateway, mobile terminal equipment, system software and terminal software. The sensor node and mobile sensing equipment acquire label information by the RFID reader; then data is transmitted to wireless sensor network gateway equipment by a wireless sensing module; the gateway equipment transmits the data to the terminal equipment through an infrastructure network by realizing seamless handover between the wireless sensor network and the Ethernet as well as a wireless local area network; in the coverage area of the wireless network, all relative mobile equipment, such as a PDA (Personal Digital Assistant) and an intelligent mobile phone, can be conveniently and rapidly used to acquire required information; and finally, the intelligent residential district system on the basis of RFID in the wireless sensor network is realized.

Description

Technical field [0001] The invention involves a design and implementation scheme of wireless communication system based on wireless sensor networks, and the implementation of the system on the RFID terminal reading and writing equipment., Belong to the cross -field of wireless sensor network, RFID, wireless communication. Background technique [0002] RFID (radio frequency recognition) is a non -contact automatic recognition technology. Its basic principle is to use radio frequency signals and space 藕 (inductance combination or electromagnetic ravioli) transmission characteristics to achieve automatic recognition of identified objects. It has many traditions.The unparalleled advantages of automatic recognition technology, such as non -contact, long distance, readable and writing, large information, large amount of information, no need to intervene in manual intervention, multi -target recognition at the same time. [0003] Electronic tags are divided into active electronic tags ...
