Abstract

The invention relates to a wireless positioning method with a fingerprint identification function. With the method adopted, the problem of incapability of a fingerprint identification roll calling method to realize wireless and remote operation in the prior art can be solved. According to the method of the invention, a fingerprint identification technology and an RSSI-based positioning technology are adopted. The method includes the following steps that: step 1, fingerprint collection of the wearers of wireless beacons, as well as registration and storage of corresponding ID numbers are carried out at a PC; step 2, the wireless beacons carry out roll calling, a main control chip compares obtained fingerprint information with fingerprint information collected in registration, carries out data processing, sends a roll calling result and ID information corresponding to the roll calling result; step 3, a wireless signal receiving end receives wireless signals through using a direction-finding antenna; and step 4, the wireless signals received by the direction-finding antenna are processed and analyzed through the PC, and processing and analysis results are displayed on the terminal PC. When the wireless positioning method of the invention is applied to a wireless communication environment, the wireless beacons are convenient and quick to use, and monitoring and positioning can be realized with a roll calling task completed.

Description

technical field [0001] The invention relates to a locating method, in particular to a wireless locating method fused with fingerprint identification. Background technique [0002] RSSI is the received signal strength indication, and the signal receiving point receives the signal from the signal source through the directional antenna. According to the relationship between the RSSI of the received signal and the distance d of signal transmission , where n represents the signal propagation constant and A is an empirical parameter. The transmission distance of the signal can be obtained indirectly through the relationship between RSSI and d. In addition, at the signal receiving end, the signal is received through a directional antenna, and in this way, the location area where the received signal is located can be determined. Then, according to the calculated transmission distance, the location information of the signal source can be obtained. In the present invention, it is...
