System and method for wireless network signal scope sensing and displaying

Abstract

The invention provides a system and a method for wireless network signal scope sensing and displaying. A vehicle-mounted terminal device periodically obtains present wireless network signals and a latitude and longitude coordinate, and periodically sends the wireless network signals and the latitude and longitude coordinate back to a rear-end cloud server. The cloud server can draw a transmission scope of each region according to the wireless network signals and the latitude and longitude coordinate set back by the vehicle-mounted device and by means of a convex hull algorithm. Thus signal conditions in road segments which no vehicle passes can be compensated. Conditions that a same area is covered by a plurality of regions are analyzed according to the transmission scope. Which area is not covered by any region or is only covered by one region and located at the edge of the region is determined according to the region covering conditions, thus determination of poor mobile communication receiving or communication corner areas is realized, and reference is provided for operating supporting.

Description

【Technical field】 [0001] The present invention is a signal detection system and method, especially a system and method for wireless network signal range detection and display. 【Background technique】 [0002] At present, in many existing technologies, the transmission range of the base station is assumed to be circular or fan-shaped, and a specific transmission distance is given. However, in real life, the network signal may be affected by the environment and shelters, resulting in a transmission range that may not be as ideal as a circle or fan. In addition, there are also related existing technologies that use vehicle-mounted equipment to drive on the road and collect the cell identification codes and signal strengths corresponding to each location point. However, if the road sections that have not been driven will not be able to know their signal conditions, this method may be affected. Limited to the number of locations reported by the on-board device. 【Content of inve...
