Vehicle monitoring method

Abstract

The invention relates to a vehicle monitoring method, which relates to a traffic control method of road vehicles. The traffic management center sends an instruction to the vehicle-mounted terminal with GPS of the monitored vehicle; the monitored vehicle receives and stores the instruction; the vehicle-mounted terminal takes the first effective GPS point after receiving the instruction as the initial position latitude and longitude of the vehicle and sends it to The traffic management center then repeatedly calculates the mileage of the vehicle based on the current latitude and longitude of the vehicle and reviews the previous latitude and longitude, and adds it to the total mileage data until the conditions specified by the command are met. Traffic management center: The traffic management center receives and displays the latitude and longitude, total mileage data and current time of the monitored vehicle at that time, and accepts inquiries. It can increase the number of monitored vehicles, reduce communication costs, simplify display content, and expand the scope of monitoring.

Description

technical field [0001] The invention relates to a traffic control method of road vehicles, in particular to a monitoring method for vehicle running of a vehicle-mounted terminal equipped with a satellite positioning receiver (GPS). technical background [0002] At present, domestic monitoring methods for vehicles mainly utilize vehicle-mounted terminals with satellite positioning receivers (GPS). The wireless communication method sends the real-time latitude and longitude information of the vehicle to the traffic management center. The traffic management center stores the latitude and longitude information of each monitored vehicle and calculates the driving trajectory of each vehicle, and displays the trajectory and position of each vehicle on the electronic map display screen. and accept inquiries. The monitored vehicle can actively send the latitude and longitude information of the vehicle to the traffic management center for monitoring, or passively accept the monitorin...

AI Technical Summary

Problems solved by technology

This monitoring method has the following disadvantages: 1. When the number of monitored vehicles is large, the display of the track and position of each vehicle on the electronic map display screen will make people dazzled, and the monitoring effect is not good.

2. The frequent expenses of each vehicle to the traffic management center for longitude and latitude information communication are too large

3. When it is necessary to know the running mileage of each vehicle, the traffic management center must convert the trajectory of each vehicle into the running mileage, and once a vehicle drives outside the monitoring range displayed on the electronic map, neither the trajectory can be displayed nor the vehicle can be clarified Mileage
