Accompanying drawing explanation
Fig. 1 is the theory diagram of a kind of embodiment of visible ray speed-measuring system of highway of the present invention.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention will be further described:
Refer to Fig. 1, visible ray speed-measuring system of highway of the present invention comprises optical signal generating apparatus 1, light signal receiving 2, signal processing apparatus 3, vehicle information collecting device 4, information provider unit 5 and dispatch control monitor terminal 6.Described optical signal generating apparatus 1 is for providing the light source be irradiated on the vehicles, and it can be traffic lights or street lamp etc.In the present embodiment, described optical signal generating apparatus 1 is the LED traffic signal lamp for providing described light source, described LED traffic signal lamp can be arranged on tunnel face or crossroad, it has provides test the speed light source and traffic signals dual-use function, existing traffic lights resource can be made full use of, thus can reduce costs, be convenient to popularize.
Described light signal for receiving the light signal be reflected back from the described vehicles, and is converted to electric signal and is sent to described signal processing apparatus 3 by described light signal receiving 2.In the present embodiment, described light signal receiving 2 is photoelectric commutators, and described signal processing apparatus 3 is dsp processors.When a certain vehicle approaches towards described LED traffic signal lamp, under the control of described dsp processor, described LED traffic signal lamp is to described vehicle emissions light beam signal, described light signal runs into described vehicle back reflection and returns, described photoelectric commutator converts described light signal to electric signal and is transferred to described dsp processor, described dsp processor is according to the launch time of described light signal and time of reception, calculate the propagation distance of white light signal, and then calculate the distance of vehicle and described light signal receiving 2.After a period of time, then repeat said process, then, the distance of twice vehicle and described light signal receiving 2 is asked poor by described dsp processor, just draw the distance of vehicle this period, this distance and this time period ask business, just draw the average velocity of described vehicle.
Described vehicle information collecting device 4 is for sending the information of vehicle to described light signal receiving 2.Described information provider unit 5 can be display screen, voice device or signal lamp, and it can be used for providing vehicle speed information, traffic information, Weather information or advertising message.In the present embodiment, described vehicle information collecting device 4 and described information provider unit 5 are imageing sensor and loudspeaker respectively.Described imageing sensor for taking the license plate number of vehicle, and sends corresponding license plate number information to described dsp processor.If when the speed of described vehicle exceedes the speed of a motor vehicle that this section specifies, then described dsp processor transmits speed information and the information of this vehicle to described loudspeaker, makes driver's regulation speed, thus can reduce the situation producing traffic accident because of hypervelocity.
In addition, described dsp processor also sends the license plate number information of described vehicle, vehicle speed information and time to described dispatch control monitor terminal 6 by network by network.Described dispatch control terminal 6 can be handheld terminal or computer server etc., and in the present embodiment, described dispatch control terminal 6 is computer servers.The velocity information that traffic police shows according to described dispatch control monitor terminal 6 is dispatched the vehicles.Such as, if the base speed that the speed of described vehicle requires lower than this section, then illustrate that this road section traffic volume is crowded or traffic hazard occurs, thus traffic police can rush towards scene in time, solves various accident.In addition, also transmit traffic information, Weather information or advertising message by described dispatch control monitor terminal 6 to described dsp processor, and then transmit described traffic information, Weather information or advertising message by described dsp processor to described loudspeaker, be thus convenient to driver and understand road conditions and weather etc.
In sum, visible ray speed-measuring system of highway of the present invention is by the cooperation between above-mentioned each device, can directly utilize existing traffic lights, just can realize testing the speed to the vehicles, solve existing contact speed measuring device and the defect existing for non-contact speed measuring device, its structure is simple, be convenient to the low and dependable performance of maintaining, cost.
