Preferably, the alarm module is combined aural and visual alarm.
Utility model has the advantages that using wireless sense network, it can not be by items such as sleet dense fog night and bends
The influence of part ensure that and data are transmitted ground interior ground control module and then accurately calculate spacing, it is ensured that traffic safety
Distance reduces the generation of rear-end collision.The urgent send button function of failure can send rear for information such as accident spots
The probability of rear-end collision accident generation is effectively reduced in vehicle.
Detailed description of the invention
Below to each width attached drawing of the utility model specification expression content and figure in label be briefly described:
Fig. 1 is the utility model data transmission principle figure；
Fig. 2 is the utility model security system structural block diagram.
Specific embodiment
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
For, because of low visibility, causing front and back following distance close under the weather such as misty rain, being easy to happen the problem of knocking into the back, originally
Patent sends the information such as self-position, speed using interior R-T unit and receives along highway arranged for interval wireless receiving and dispatching website
Other information of vehicles that website is sent.Control module calculates the actual range of same front truck, control module control by these information
Display module shows leading vehicle distance and issues light and sound alarm when distance is less than threshold value.For because rear-end collision occurs
Afterwards, the problem of front vehicle can not learn front situation in time, and the chain of rings is caused to knock into the back, this patent utilizes danger button, passes through receipts
Hair website rearward sends emergency episode information, knocks into the back to avoid the chain of rings.It is specific as follows:
Driving safety system based on wireless sensor network, including arranged along Highways ' wireless signal transceiver station,
Onboard wireless signal receiving/transmission device, travelling data acquisition module, control module, display module, combined aural and visual alarm are set in the car,
Control module obtains module with display module, travelling data respectively, onboard wireless signal receiving/transmission device is connect, onboard wireless signal
R-T unit and wireless receiving and dispatching website communicate to connect.
Control module obtains module acquisition travelling data by travelling data and will by onboard wireless signal receiving/transmission device
