Abstract
Disclosed is an automatic alarm unit for highway accidents. Wireless signal receivers are disposed at entries and medians of a highway at certain intervals. Outputs of the wireless signal receivers are connected with an input end of a controller. A wireless signal transmitter is arranged in each vehicle and operates under the same frequency as the wireless signal receivers. Each wireless signal transmitter is provided with a unique address code and constantly transmits an address code signal out, and the transmitting distance is smaller than one half of the distance between the two wireless signal receivers. The controller determines identity and location of each vehicle according to received address code. Alarm signal lamps are disposed on each median of the highway at certain intervals and are connected with an output end of the controller. When one wireless signal receiver receives the address code signal of the vehicle, next controller is informed of starting timing. When the set time is up and the wireless signal receives no address code signal of the vehicle, the controller turns on the alarm signal lamps behind the vehicle to inform following vehicles to slow down and stop. The automatic alarm unit for highway accidents can be used for detecting occurrence of vehicle accidents and the vehicles running at the speed smaller than the safety speed, and timely sends out alarm signals to reduce rear-end collisions of vehicles.
Description
Technical field
The present invention relates to a kind of expressway traffic accident autoalarm of installing on accident alarming equipment, particularly highway.
Background technology
after highway has an accident, because the vehicle that can not in time approach at a high speed the rear sends alerting signal, cause the more vehicles in back to recur rear-end collision, cause larger Loss of Life and property, the vehicle how in the shortest time after accident occurs, notice is travelled later, the driver can be made rapidly vehicle deceleration and stop, when having forwardly the vehicle that travels lower than safe speed simultaneously, driver on front vehicle can be known as early as possible before accident occurs, take necessary safety practice, therefore need to arrange the accident autoalarm on highway, and the vehicle that travels at a slow speed and have an accident can be detected exactly, provide alerting signal to seem very important to the rear driving vehicle in time.
Summary of the invention
The object of the invention is to provide a kind of expressway traffic accident autoalarm, and it accurately reflects the information of driving vehicle by set wireless signal receiver, by the controller control signal lamp, the car accident alerting signal is in time sent.
For achieving the above object, the present invention adopts following technical scheme:
a kind of expressway traffic accident autoalarm, it is to be provided with at a certain distance a wireless signal receiver on expressway entrance and exit place and isolation strip, its output Articulation Controller input end, be provided with wireless signal transmitter on vehicle, its frequency of operation is identical with the wireless signal receiver frequency of operation, it is characterized in that each wireless signal transmitter is provided with unique geocoding, and continuous its address coding signal of outwards emission, its transmitting range is less than 1/2nd of two wireless signal receiver spacings, controller is confirmed its testing vehicle register and position according to the geocoding that receives, be provided with at a certain distance a warning light on highway isolation belt, it connects with the output terminal of controller, when certain wireless signal receiver receives signals of vehicles, notify next controller to begin timing to this vehicle, in setting-up time, next wireless signal receiver receives this vehicle address coding signal, controller makes zero and restarts timing the timing of this vehicle, when timing surpasses setting-up time, next wireless signal receiver does not receive this to signals of vehicles, controller is connected several warning lights of this vehicle back, the vehicle deceleration of notice back stops.
Described wireless signal transmitter is arranged on the remote-control key of vehicle, and the plug on remote-control key is provided with supply hub and vehicle power goes between connects.
Described wireless signal transmitter is arranged on the IC-card of providing in the place, expressway access, and this IC-card is provided with attaching plug and connects with vehicle-mounted power socket.
Described warning light is arranged on the fixed support of each wireless signal receiver.
The fixed support of described each wireless signal receiver is provided with a solar cell, and it provides electric power for wireless signal receiver, controller, signal lamp.
Described warning light is coston light, and controller is connected respectively the signal lamp of different colours according to the distance of distance alarm vehicle.
On described vehicle, wireless signal transmitter sends to geocoding the wireless signal receiver of place, expressway access and service area exit setting, start controller to the timing of this vehicle, on vehicle, wireless signal transmitter sends to geocoding the wireless signal receiver of expressway exit place and service area porch, the timing of stop control to this vehicle.
The host computer of described controller is a supervisory control comuter, is provided with telecommunication cable between them and communicates, and supervisory control comuter is provided with telecommunication cable and connects with display, and each wireless signal receiver and signal lamp are provided with unique numbering in supervisory control comuter.
Described controller is by comparing the time of reception of two of front and back wireless signal receiver to a certain signals of vehicles on the isolation strip, when difference greater than the safety time setting value, be that Vehicle Speed is less than safe speed, controller is connected this vehicle front signal lamp, sends the safety instruction wigwag to this vehicle.
when vehicle enters Entry to motorway place and service area exit, the geocoding that wireless signal transmitter on vehicle sends this car is to the wireless signal receiver in Entry to motorway place and service area exit, the controller work that connects with wireless signal receiver, input signal begins this vehicle timing for next controller, with Time Controller, the vehicle geocoding that wireless signal receiver receives is issued the supervisory control comuter write address, vehicle is at running on expressway, every through a wireless signal receiver on the isolation strip, wireless signal transmitter on vehicle just sends to its unique address coding the wireless signal receiver on the isolation strip, before the timing setting value does not arrive, next wireless signal receiver receives the address coding signal of wireless signal transmitter on this vehicle, controller makes zero to the timing of this vehicle, and notify next controller to begin timing, the like, if controller has arrived setting value to this vehicle timing, next wireless signal receiver does not also receive the address coding signal of this vehicle, controller starts several signal lamps of this rear view of vehicle that its output terminal connects, send the accident alarming signal, when vehicle enters service area porch and high speed exit, wireless signal transmitter on vehicle sends to the geocoding of this vehicle the wireless signal receiver in service area porch and high speed exit, controller is cancelled the timing to this vehicle, for the front vehicle lower than safe velocity that do not have an accident, controller is by comparing the mistiming of two the wireless signal receiver reception signals in front and back on the isolation strip, when difference during greater than setting value, namely surpass the security regulations time, illustrate that Vehicle Speed allows safe speed per hour less than minimum, controller is connected the signal lamp of this vehicle front, this vehicle is sent the safety instruction wigwag.
The advantage of this invention is that the geocoding that controller passes through the wireless signal transmitter that wireless signal receiver receives confirms that each is through the identity of vehicle, avoid the sensor error signal that exists vehicle cut-ins to cause due between check point place's vehicle parallel running and two wireless signal receivers, the generation of car accident and the vehicle that travels lower than safety standard speed can accurately be detected, timely vehicle rearwards sends alerting signal, reduces the rear-end collision of highway.
The invention will be further described below in conjunction with accompanying drawing.
