Mobilephone positioning system and method

Abstract

The invention discloses a mobilephone positioning system and method, relating to the technical field of mobile equipment positioning and aiming at solving the technical problem of improving positioning precision. The mobilephone positioning system comprises a mobilephone, a positioning server and a plurality of ultrasonic transmitters for transmitting ultrasonic signals; all the ultrasonic transmitters are respectively arranged in all positioning monitoring areas, and each ultrasonic transmitter is provided with an equipment code; the mobilephone is internally provided with a wireless networkmodule, a microphone for receiving the ultrasonic signals and a ultrasonic data processing module for processing the ultrasonic signals; the ultrasonic data processing module of the mobilephone is provided with an ultrasonic signal input port and an ultrasonic signal output port, wherein the ultrasonic data input port is connected with the microphone, and the ultrasonic data output port is connected with the wireless network module; and the wireless network module of the mobilephone is connected with the positioning server through a wireless network. According to the mobilephone positioning system, whether the mobilephone enters smaller areas, such as shops, offices and the like can be judged.

Description

technical field [0001] The invention relates to mobile device positioning technology, in particular to a mobile phone positioning system and its positioning method. Background technique [0002] At present, the application of mobile Internet is becoming more and more extensive. When a mobile phone enters a certain area, it can query the relevant information in the area through the mobile Internet. Promotional information, and then complete consumption at the merchant according to the queried information to obtain discounts. [0003] But, the information that provides on the Internet is very much, after mobile phone enters a certain area, mobile phone user often needs to spend a long time just can find the relevant information of this area from Internet by mobile phone. [0004] Therefore, if the mobile phone can send the relevant information of its area to the mobile phone after it enters a certain area, it can save the mobile phone user's time to find the relevant informat...

Problems solved by technology

However, this method requires precise positioning of the mobile phone, that is, the positioning system of the mobile phone needs to be able to monitor whether the mobile phone enters a specific positioning monitoring area (such as a certain indoor area)

[0005] Existing mobile phones use GPS satellites combined with network (Network) and base station (Cell-ID) for comprehensive positioning. When multiple satellites can be connected outdoors, the accuracy can reach tens of meters or even several meters. If The satellite signal is not good, the accuracy is about 100 meters to 800 meters, if there is no satellite and network signal, only the phone signal, the accuracy is even worse, about 2000 meters, and no matter how high the positioning accuracy is, it can only be based on The location information provided by the mobile phone's GPS positioning system knows the geographical location of the mobile phone, and it is impossible to determine whether the mobile phone has entered a specific positioning monitoring area (such as an indoor area) in the geographical location. The provided location information sends relevant information about the location monitoring area to the mobile phone in a targeted manner

[0006] It can be seen that the defect of the existing GPS positioning system for mobile phones is that it is impossible to determine whether the mobile phone enters a specific positioning monitoring area, so that the precise positioning of the mobile phone cannot be realized, and thus it is impossible to send the information related to the positioning monitoring area to the mobile phone. application of information
