Abstract
The utility model relates to a vehicle overspeed prevention device based on WSN, which comprises wireless sensor nodes respectively arranged on the roadside and in the vehicle and communicated with each other, and is characterized in that: the output ends of the wireless sensors in the vehicle are connected with the input end of a singlechip, and the singlechip is also connected with a vehicle speed data output end and an alarm module. The wireless sensor network nodes transmit the speed limit value of the road section to the wireless sensor node in the vehicle, and then the speed limit value is inputted to the singlechip and is compared with the actual vehicle speed, the singlechip judges if the vehicle is in overspeed state, if so, the alarm sends an alarm, when the vehicle is in serious overspeed state, the vehicle overspeed prevention device also can transmit the alarm information to a far-end server of the traffic police department, so the traffic police department can take corresponding measures to handle the situation. The vehicle overspeed prevention device based on WSN not only can prevent the overspeed situation for drivers, but also can inform the traffic police about the serious overspeed situation in time.
Description
Technical field
The utility model relates to a kind of vehicle overspeed preventer based on wireless sensor network.
Background technology
" ten accident nine times fast " this popular safe driving caveat, the driver has probably learnt off, has listened tired, still, brings about great losses, pays the traffic hazard constantly generation still of the cost of blood owing to driving over the speed limit.Existing hypervelocity management mainly is to lean on video and some to move the candid photograph video camera to finish, adopt these modes to tend to occur hypervelocity and not found situation, directly caused the driver to have that thinking by sheer good luck overtakes other vehicles can not be found at heart, also exist some drivers not know how many speed limits in this highway section is and overtakes other vehicles because of carelessness and by the situation of being imposed a fine. how reducing the hypervelocity phenomenon effectively, is the key issue that cuts down traffic accidents.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle overspeed preventer based on wireless sensor network, reminds the driver to slow down when this system is mainly used in overspeed of vehicle.
The utility model adopts following scheme to realize: a kind of vehicle overspeed preventer based on wireless sensor network, comprise: intercommunication and be located at the wireless sensor node of roadside and Che Nei respectively mutually, it is characterized in that: the output terminal of the wireless sensor node in the described car is connected with the input end of single-chip microcomputer, and described single-chip microcomputer also is connected with vehicle speed data output terminal and alarm module.
Described far-end server is connected with the wireless sensor node of being located at the roadside.
The utility model adopts wireless sensor network to come transmission signals, can in time issue the speed limit instruction of respective stretch, if driving vehicle has the hypervelocity behavior, device can initiatively remind the driver to slow down, release souls from purgatory if continue, device will give the alarm to system server and be handled by traffic police department, is a kind of practical and effective overspeed preventer.
Description of drawings
Accompanying drawing 1 is based on the vehicle overspeed preventer structural drawing of wireless sensor network.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model provides a kind of vehicle overspeed preventer based on wireless sensor network, comprise: intercommunication and be located at the wireless sensor node of roadside and Che Nei respectively mutually, it is characterized in that: the output terminal of the wireless sensor node in the described car is connected with the input end of single-chip microcomputer, and described single-chip microcomputer also is connected with vehicle speed data output terminal and alarm module.Described far-end server is connected with the wireless sensor node of being located at the roadside.
In preferred embodiment of the present utility model, far-end server described in the utility model adopts IBM System x3650 M2 (7947R66) server, be used for some essential informations of store car essential information, roadside wireless sensor network and warning message etc., wireless sensor network adopts TinyOS operating system.Voice guard is GSM-A, and single-chip microcomputer is 51 series A T89S52.
The wireless sensor network node in roadside sends to the speed limit numerical value in this highway section the wireless sensor node of automobile, wireless sensor node on the automobile is transferred to single-chip microcomputer with speed limit numerical value after receiving speed limit numerical value, single-chip microcomputer compares this numerical value and the speed that receives when car speed represents overspeed of vehicle (every 3 seconds more once) during greater than current up-to-date speed limit numerical value, installs to give the alarm by voice guard.If the vehicle long period (5 seconds) is in overspeed condition or overspeed seriously state (hypervelocity 30%) system will send warning message by the wireless sensor node of the wireless sensor node on the car to the roadside, the wireless sensor node in roadside is responsible for processing to the server transmission information of traffic police department by traffic police department by Wireline again.Here the wireless sensor node that is noted that each roadside all has internal number, and the numbering that also has traffic police department to give of the wireless sensor node on the automobile, so that unified communication and management.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (2)
