[0047]
[0048] A piece of data is currently collected, data number 3.
[0049] The data numbered 1 and the data numbered 3: the time difference is 11 seconds, satisfying 0~5 minutes; the distance calculated by the latitude and longitude of the two data is 4 meters (the calculation method is based on the latitude and longitude of any two points on the earth, How to calculate the distance between two points ） , satisfy the distance range of 0~100 meters; the direction interpolation value is 3 degrees; satisfy -10~+10 degrees; therefore, the data numbered 1 is related data.
[0050] The data numbered 2 and the data numbered 3: the time difference is 3 seconds, satisfying 0~5 minutes; the distance calculated by the latitude and longitude of the two data is 10 meters (the calculation method is based on the latitude and longitude of any two points on the earth, How to calculate the distance between two points ） , satisfy the distance range of 0~100 meters; the direction interp...

The invention relates to a method for acquiring traffic road conditions on the basis of time, satellite positioning, OBD (on-board diagnostics) and a wireless network. The method includes acquiring time, position, direction and vehicle running speed data by the aid of equipment provided with a satellite positioning module, an OBD module and a wireless communication module, transmitting the data to a server via the wireless network and enabling the server to write the data into a database; enabling the database to perform a certain algorithm to process the data, generating traffic road condition information and storing the traffic road condition information. The method has the advantages that the traffic road condition information can be timely and accurately acquired by the method, so that drivers can be assisted in reasonably selecting running routes and avoiding traffic jam road sections, and the pressure on the jam road sections is relieved; and historical traffic road condition data can be provided, so that the method is favorable for a traffic management department to guide traffic, and traffic conditions can be analyzed and optimized.
Description
technical field [0001] The invention relates to a traffic road condition collection method, in particular to a traffic road condition collection method based on satellite positioning, OBD and wireless communication. Background technique [0002] With the improvement of people's living standards, the number of cars in cities is getting higher and higher. Especially in big cities, congested traffic conditions become the biggest obstacle to travel by car. Timely and accurate traffic and road condition information will help drivers choose reasonable driving routes, avoid traffic jams, and relieve the pressure on congested roads. [0003] At present, the most common collection methods of traffic conditions mainly include the following methods: 1. In a fixed location, install a camera to collect images, and determine the traffic conditions through the images; 2. A large number of traffic volunteers communicate through SMS, Weibo, etc. Send the traffic conditions of the location ...
