Wireless communication switching system and method based on MiWi or ANT+ interoperation technology

Abstract

The invention relates to a wireless communication switching system and method based on a MiWi or ANT+ interoperation technology. The system is connected through at least one mobile terminal receiving-transmitting module, a node router, a transmitting device, a sensing node and a server switch, and is used for feeding corresponding information to a corresponding mobile terminal receiving-transmitting module, so that the technical problems of greater convenience and higher rapidness for data access of a mobile data service terminal and high node energy consumption are solved, the node power consumption of the node router is lowered more importantly while data access of the mobile data service terminal is more convenient and rapider, and real-time exchange of distance information through a light rail or walking to an airport can be realized through technical coverage such as ANT+, MIWI and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless communication and relates to an information exchange system, in particular to a wireless communication exchange system and method based on MiWi or ANT+ interoperability technology. Background technique [0002] In the current prior art field, the wireless tour guide system usually has the following three main modes; [0003] 1. The system method of infrared transmitter + receiving terminal has the advantages of low cost of system implementation, 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 w...

AI Technical Summary

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 large

[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, 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 is that 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

[0025] This device is an embedded server and requires a proximity sensor (passive RFID: NFC) information reader (example: antenna part and reader, size without power supply is about 43mm × 70mm), so the short-range The installation place of the sensor terminal is limited (for example, it cannot be installed on a glass window, etc.)

[0026] (3) Power consumption:

[0029] It cannot be easily moved due to the need to secure the power supply

[0030] (5) Equipment cost:

However, the GPS installed on the mobile phone has low positioning accuracy in dense streets, underground, indoors and other places, and cannot accurately locate the correct current position of the user
