In the prior art, if the user wants to record the track point through the location information, it needs to rely on external signals, such as GPS, wireless network, base station, etc., and must also have an electronic map of the place. Indoor location information records often use signal recognition methods such as WIFI, micro base station, and RFID. The signal source must be densely distributed in the area. The terminal can only locate the signal after receiving the signal. If the external signal is not used in complex situations such as underground parking lots, indoors, and mountains, , positioning and track recording can not be completed. At the same time, the accuracy of the track record is limited by the accuracy of the external signal, which is difficult to meet the user's requirements for track accuracy. The biggest problem of the existing solution is that the cost is too high and the use is complicated. The user must connect the signal and download the electronic map to use it.

The type of signal collected by the network signal acquisition module can be set by the user, or can be automatically configured by the network signal acquisition module according to the current mobile phone usage, and the network signal acquisition module works as shown in FIG.

The network signal track record module receives the signal strength and signal quality data collected by the network signal acquisition module, and receives the somatosensory posture acquisition module to record the user's walking track point and direction, and saves the data to the database. The database stores the corresponding network signal strength and quality information according to the user's walking track point, orientation, time period and the like. The coverage of the track point (ie, the accuracy of the acquisition) can be set manually by the user, or can be automatically set by the terminal according to factors such as the user's pace. Network signal strength and quality acquisition methods can be the same each time The database record is updated immediately after the signal strength is collected on the track point.
