Abstract

The utility model discloses a vehicle rear-end collision early warning system based on GPS (Global Positioning System) locating information and a wireless communication network. The early warning system adopts the structure that vehicle-mounted GPS terminals are arranged on a plurality of running vehicles; the plurality of vehicle-mounted GPS terminals are in wireless communication connection with a database for storing GPS position information; a background server is connected with the database; and a data acquisition unit, a front-and-rear vehicle operating data calculating unit and an alarming decision-making unit are arranged on the background server in wireless communication connection with the vehicle-mounted GPS terminals, wherein the data acquisition unit is used for acquiring the current position data of the front and rear vehicles, the front-and-rear vehicle operating data calculating unit is used for calculating the operating data of the front and rear vehicles, and the alarming decision-making unit is used for judging whether alarming is needed or not according to the operating data of the front and rear vehicles. The vehicle rear-end collision early warning system based on GPS locating information and the wireless communication network can effectively prevent rear-end collision and guarantees safe running of the vehicles.

Description

Vehicle rear-end collision early warning system based on GPS locating information and cordless communication network

Technical field

The utility model relates to a kind of vehicle rear-end collision early warning system based on GPS locating information and cordless communication network.

Background technology

Rear-end collision on fastlink, often occurs, still, never have good solution for a long time, therefore, be necessary to research and develop a kind of anti-electronic prealarming system that knocks into the back.

The utility model content

Technical problem to be solved in the utility model is to propose a kind of vehicle rear-end collision early warning system based on GPS locating information and cordless communication network, should can effectively prevent that rear-end collision from the support vehicles driving safety taking place based on the vehicle rear-end collision early warning system of GPS locating information and cordless communication network.

Technical solution of the present utility model is as follows:

A kind of vehicle rear-end collision early warning system based on GPS locating information and cordless communication network, on many vehicles of current operation, be equipped with GPS terminal, a plurality of GPS terminals all are connected with the database radio communication that is used to store the GPS positional information, background server links to each other with database, and background server is provided with 1) be used to obtain before and after the data capture unit of vehicle current location data, 2) be used to calculate before and after the front and back vehicle operation data computing unit and 3 of vehicle operation data) be used for judging whether the warning decision package that needs are reported to the police according to the front and back vehicle operation data; Vehicle distances before and after described front and back vehicle operation data comprises, at the back vehicle speed, at back vehicle heading and at preceding vehicle speed; Background server is connected with the GPS terminal radio communication.

Described background server is provided with the cloud computing processor.

Beneficial effect:

Vehicle rear-end collision early warning system based on GPS locating information and cordless communication network of the present utility model, adopt the GPS location technology to determine the position of vehicle, and the GPS locator data of upgrading by per second, the distance of vehicle and the speed of front and back vehicle before and after calculating, when reaching alert if, in time for vehicle sends warning, prompting is suitably slowed down at the back vehicle, can effectively reduce the generation of vehicle rear-end collision accident.

Description of drawings

Fig. 1 is the structural representation of embodiment 1;

Fig. 2 is the workflow diagram based on the vehicle rear-end collision early warning system of GPS locating information and cordless communication network of embodiment 1.

Embodiment

Below with reference to the drawings and specific embodiments the utility model is described in further details:

Embodiment 1:

Referring to Fig. 1, a kind of vehicle rear-end collision early warning system based on GPS locating information and cordless communication network, on many vehicles of current operation, be equipped with GPS terminal, a plurality of GPS terminals all are connected with the database radio communication that is used to store the GPS positional information, background server links to each other with database, and background server is provided with 1) be used to obtain before and after the data capture unit of vehicle current location data, 2) be used to calculate before and after the front and back vehicle operation data computing unit and 3 of vehicle operation data) be used for judging whether the warning decision package that needs are reported to the police according to the front and back vehicle operation data; Vehicle distances before and after described front and back vehicle operation data comprises, at the back vehicle speed, at back vehicle heading and at preceding vehicle speed; Background server is connected with the GPS terminal radio communication.

Described background server is provided with the cloud computing processor.

Each vehicle on road of travelling all can be seen 1000 meters of predictions, the positional information of all vehicles in 100 meters of the backsights.On the display screen of GPS terminal, this vehicle is distinguished all the other vehicles for blue sign.

Calculate 1000 meters of this vehicle predictions in real time, the distance and the velocity contrast information of vehicle and this vehicle in 100 meters scopes of backsight.

If this car is C0, all the other are C1,

Satisfy condition:

(1)、C0-C1＞30KM/h

(2), S (C0, C1)＜100 meter

(3), direction is identical

If satisfy above-mentioned 3 conditions simultaneously, then start and report to the police, the attribute that the danger sign is set this moment is 1.

As shown in Figure 2, the vehicle rear-end collision early warning system based on GPS locating information and cordless communication network of present embodiment, its course of work is as follows:

1. GPS terminal is installed on vehicle, real-time GPS location is carried out in the position of vehicle, data such as the location of vehicle or speed finally are stored in the database.

2. with the GPS locator data of collecting, utilize wireless network transmissions to give backstage cloud computing processor.

3. in backstage cloud computing processor, the GPS locator data of collecting is calculated in real time, variation by per second GPS locator data, operational factors such as the actual displacement direction of calculating vehicle and speed, and the operational factor of above-mentioned operational factor and front truck compared, draw the result of calculation that whether has rear end collision.

4. give GPS terminal with result of calculation by wireless network transmissions.

Claims

1. vehicle rear-end collision early warning system based on GPS locating information and cordless communication network, it is characterized in that, on many vehicles of current operation, be equipped with GPS terminal, a plurality of GPS terminals all are connected with the database radio communication that is used to store the GPS positional information, background server links to each other with database, and background server is provided with 1) be used to obtain before and after the data capture unit of vehicle current location data, 2) be used to calculate before and after the front and back vehicle operation data computing unit and 3 of vehicle operation data) be used for judging whether the warning decision package that needs are reported to the police according to the front and back vehicle operation data; Vehicle distances before and after described front and back vehicle operation data comprises, at the back vehicle speed, at back vehicle heading and at preceding vehicle speed; Background server is connected with the GPS terminal radio communication.
