Problems solved by technology

[0002] In daily life, map-based applications are becoming more and more widely used. Usually, the drawing of maps generally adopts the method of manual surveying and mapping. Manual surveying and mapping requires professional surveyors and tools to assist, requires a lot of manpower and material resources, and is more efficient. Low, not easy to popularize and apply
Now with the development of science and technology, aerial photography technology is gradually developing, and it is gradually being applied to map drawing. First, photos are taken through aerial photography technology, and then the surveying and mapping department conducts map surveying and mapping. After monitoring vehicles, real-time GIS information is obtained. This method of surveying and mapping maps requires professionally qualified departments, which has high technical requirements for personnel, which makes the cost of map drawing relatively high, which is not conducive to popularization and application, and the information involved in this drawing process involves many aspects of privacy and security. The problem is that the involvement of multiple personnel can easily lead to the loss of these information, and the security is also affected

Embodiment 1

[0018] combine figure 1 As shown, the virtual road drawing is drawn for the virtual road conditions in a specific time period. First, a GPS locator and a wireless transceiver device need to be installed on the vehicle, and the specific time period of the system is set to 7:00-9:00 in the morning , 11:00-14:00 noon and 17:00-19:00 p.m., three peak time periods with large traffic flow, when the set time is up, the server issues a "start" command, and the "start" command Through the 3G wireless network, it is transmitted to the wireless transceiver device on the vehicle, and then the wireless transceiver device transfers the received instructions to the GPS locator. The GPS locator performs data collection according to the parameters of the set collection time and collection cycle. The GPS positioning on the vehicle The instrument locates the vehicle, and collects the latitude and longitude information of the positioning point during the driving process of the vehicle and the inf...

Embodiment 2

[0020] The virtual road drawing is drawn for the virtual road conditions in a specific time period. First, a GPS locator and a wireless transceiver device need to be installed on the vehicle, and the specific time period of the system is set to 7:00-9:00 in the morning and 11 at noon. :00-14:00 and 17:00-19:00 p.m., three peak time periods with large traffic flow, when the set time is up, the server will issue a "start" command, and the "start" command will be sent through 2G wireless The network is transmitted to the wireless transceiver device on the vehicle, and then the wireless transceiver device transfers the received instructions to the GPS locator. The GPS locator performs data collection according to the parameters of the set collection time and collection cycle. Carry out positioning, and collect the longitude and latitude information of the positioning point during the vehicle's driving process and the information data of the vehicle's driving speed. When the set tim...

Embodiment 3

[0022] The virtual road drawing is drawn for the virtual road conditions in a specific time period. First, a GPS locator and a wireless transceiver device need to be installed on the vehicle, and the specific time period of the system is set to 7:00-9:00 in the morning and 11 at noon. :00-14:00 and 17:00-19:00 p.m., three peak time periods with large traffic flow, when the set time is up, the server will issue a "start" command, and the "start" command will pass through 4G wireless The network is transmitted to the wireless transceiver device on the vehicle, and then the wireless transceiver device transfers the received instructions to the GPS locator. The GPS locator performs data collection according to the parameters of the set collection time and collection cycle. Carry out positioning, and collect the longitude and latitude information of the positioning point during the vehicle's driving process and the information data of the vehicle's driving speed. When the set time i...

Abstract

The invention provides an urban virtual road drawing method and a device thereof. The drawing method comprises the steps that a GPS locator and a remote wireless transceiver are arranged on a vehicle; a wireless network is set up; a vehicle private network is connected with a car networking service center server; a car networking remote monitoring platform is established; a remote service is established; a locating system on a vehicle is called; a certain time period and an acquisition period are set for the system, so that latitude, longitude and speed information data of vehicles in the whole city in designated acquisition time are acquired, and data are transmitted to the car networking service center server; nodes collected by the server are drawn into a scattergram; and a virtual road is drawn according to the scattergram. According to the invention, the vehicle locating system in car networking is used; latitude and longitude information of the vehicle are fit to acquire the road map of the whole city; the drawn virtual road map can accurately reflect urban roads; the accuracy is high; and the real-time map updating efficiency is improved.
