Abstract

The invention discloses an information collecting system which comprises an RFSN node and an aggregation node. The RFSN node is used for reading label information and collecting environment information and can communicate with the aggregation node, and the aggregation node is used for creating a communication network to communicate with the RFSN node and sending obtained information to an upper computer. The RFSN node is provided with a microcontroller, a reader transceiver, an RF transceiver, a sensor, a power source and a control module of the power source. The aggregation node is provided with a ZigBee module and a serial port communication module. The RFSN node is used for reading label information through the reader transceiver and carrying out network communication through the RF transceiver, so that flexible networking is facilitated, and the FRSN node is suitable for long-distance transmission; the reader transceiver and the RF transceiver are integrated in one node and internally communicate through the microcontroller, communication speed is greatly improved, and information distortion and mismatching in communication are lowered due to the fact that the microcontroller integrates information of the reader transceiver and information of the sensor.

Description

technical field [0001] The invention relates to an information collection system, in particular to an information collection system suitable for label collection and long-distance transmission. Background technique [0002] In practical applications, pure RFID systems and WSN systems often cannot meet actual needs. The RFID system has outstanding performance in obtaining object identity information and tracking and locating objects. However, the RFID system is a single-hop network and cannot transmit the obtained information over long distances. The WSN system has outstanding performance in obtaining environmental information, flexible networking, and long-distance transmission, but it cannot identify object identity information and location tracking. [0003] In some practical applications, it is necessary to combine RFID technology and WSN technology to meet actual needs. For example, in the application of attendance system, after the reader obtains the tag information, ...
