Abstract

The invention relates to a positioning system, and especially discloses an indoor and outdoor positioning system with an automatic switching function. The indoor and outdoor positioning system with an automatic switching function comprises an RFID tag and an RFID read-write device which are arranged correspondingly. The system is characterized in that the RFID tag is integrated with a microcontroller and embedded with a GPS module, a wireless communication module and a GSM module; the microcontroller is connected with the GPS module, the wireless communication module, the GSM module, a power module and a Flash RAM in a two-way mode; and the wireless communication module is connected with an antenna. By combining GPS, RFID, GSM and WSN, the system has an automatic switching function, indoor and outdoor complex personnel positioning, monitoring and tracking tasks are completed, a target object can be searched accurately, and real-time positioning and monitoring management of personnel and items are realized.

Description

(1) Technical field [0001] The invention relates to a positioning system, in particular to an indoor and outdoor positioning system with automatic switching function. (2) Background technology [0002] With the wide application of Internet of Things technology, it is difficult for a single GPS positioning mode to meet the requirements of continuous positioning. For example, in indoor and signal-blocked areas, the ranging error of the receiver increases and the correct positioning result cannot be obtained, or even positioning. In order to overcome the weaknesses of the GPS system, it is necessary to use a combination of GPS and other non-line-of-sight vector positioning methods to achieve positioning in a weak signal or no navigation signal environment. [0003] RFID and WSN are the most important identification technologies in the Internet of Things. They are used in different occasions. Each has its own advantages, but each has its own shortcomings, which limit the scope o...
