Vehicle monitoring method

Abstract

The invention is a vehicle monitoring method, relating to a road vehicle traffic control method: the traffic management center sends an instruction to the GPS-comprising vehicle terminal of monitored vehicle; the monitored vehicle receives and stores the instruction; the vehicle terminal uses the first GPS effective point that has received the instruction as the longitude and latitude of the initial position of the vehicle and sends them to the traffic management center , and then calculates the mileage of the vehicle repeatedly according to the longitude and latitude of the vehicle at that time and by reviewing the previous longitude and latitude and adds the mileage to the total mileage data until the specified condition is met and then sends the longitude and latitude at that time and the total mileage data to the traffic management center; and the traffic management center receives and displays them as well the current time and receives the inquiry. The invention can add the number of monitored vehicles and reduce communication fees, simplify display contents and enlarge the monitoring range.

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...

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
