Wireless self-help guide system based on WSN technical platform

Abstract

The invention provides a device for controlling a wireless self-help guide system adopting an IEEE802.15.4 protocol-Wireless Sensor Network (WSN) platform technology. Compared with the prior art, the invention has various functions of low system cost, one device with multiple purposes, sight spot wireless positioning satisfaction, less positioning error, non-contact ticket checking, corresponding sight spot explanation playing according to a specific sight spot, selective played language, optimal route promotion of the sight spot, private system taking prevention, and the like.

Description

technical field [0001] The invention relates to a wireless tour guide system, in particular to a wireless self-help guide system using the IEEE802.15.4 protocol—WSN (Wireless Sensor Network) platform technology. Background technique [0002] In the prior art field, the wireless tour guide system generally has the following three main modes; [0003] 1. The system method of infrared transmitter + receiving terminal has the advantages of low system implementation cost, no need for wiring, and simple installation; its disadvantage is that infrared rays are easily blocked by obstacles and inconvenient to use, so the market value is not great. [0004] The patent documents and known documents related to the above-mentioned technical features include: [0005] Chinese patent "Infrared Tour Guide System" (Chinese patent announcement number CN1405997A, announcement date March 26, 2003). [0006] 2. With the system mode of wireless local area network+receiving terminal, the advanta...

Problems solved by technology

[0003] 1. The system method of infrared transmitter + receiving terminal has the advantages of low cost of system implementation, no need for wiring, simple installation, etc.; its disadvantage is that infrared is easily blocked by obstacles and inconvenient to use, so the market value is not great

[0006] 2. With the system mode of wireless local area network+receiving terminal, the advantage of this mode: wireless local area network technology is mature, widely used, and its deficiency is: for the application of the field of the present invention, wireless local area network cost is higher, and a lot of resources can't be utilized at all (as High-speed transmission rate, broadband communication characteristics, quality assurance mechanism, etc.), therefore, the application market capacity is limited

[0009] 3. With the system method of GPS+PDA terminal, the advantage of this method: it can realize the wireless positioning of outdoor scenic spots, and read or listen to the narration and explanation of scenic spots through PDA; its disadvantage is that the resolution of positioning is not high (about ten meters ), it is basically impossible to locate indoors, the cost of system implementation is high, and the market application prospect is obviously not satisfactory

[0012] As far as the current market is concerned, there is no one that can achieve many practical and effective functions required in the field of the present invention at a lower system cost, such as: satisfying indoor and outdoor wireless positioning of scenic spots with small positioning errors, The wireless ticket checking function of the electronic ticket of the scenic spot can play the corresponding scenic spot commentary according to the specific scenic spot, the playback language can be selected, the best route prompt of the scenic spot and the anti-system is taken out without authorization, etc.
