Description
Technical field
The present invention relates to Bus- Speed Monitoring field, and in particular to the travel speed detection means of light-duty vehicle.
Background technology
The mode of testing the speed that China's highway is used at present is generally that uncertain fixed point tests the speed, and which results in many drivers
There is idea of leaving things to chance, arbitrarily driven over the speed limit in the interval do not tested the speed, there are many harm when driving over the speed limit, during furious driving
Driver can not comprehensively, correctly perceive the change outside in-car；Reduce cognitive ability of the driver to space；Driver is to speed
Judgement decline；Furious driving increases the degree of fatigue of driver, and respond declines；Driver can be made by driving over the speed limit
Thinking error in judgement, the operational stability for influenceing vehicle, the operating range of automobile increase, the security performance of influence vehicle.Using
Interval is tested the speed, and can be prevented effectively from driver and be produced idea of leaving things to chance, reduce the possibility driven over the speed limit.Fixed point is surveyed in the prior art
The cost of speed is higher, therefore the device for setting fixed point to test the speed is and its limited, it is impossible to effectively avoid driver from driving over the speed limit
Situation.
The content of the invention
The technical problems to be solved by the invention are that prior art pinpoints the cost height that tests the speed, and limit fixed point speed measuring device
Set, it is impossible to be prevented effectively from the situation of driver's hypervelocity, it is therefore intended that the travel speed detection means of light-duty vehicle, reduction are provided
Pinpoint the cost of speed measuring device, the density that increase highway tests the speed.
The present invention is achieved through the following technical solutions：
The travel speed detection means of light-duty vehicle, including measurement apparatus, the measurement apparatus include the list being sequentially connected
Piece machine, signal conditioning circuit, interruption time set, the interruption time set are used to detect that the length of wagon and vehicle body of vehicle to be led to
The time of the position is spent, the single-chip microcomputer carries out travel speed by the length of wagon and vehicle of vehicle by the time of the position
Detection.
By setting measurement apparatus on the way in highway, the length of wagon and vehicle of vehicle are measured in itself from the beginning to the end
By setting the time of measurement apparatus position, with regard to travel speed of the vehicle in the point can be obtained；Adjusted simultaneously using single-chip microcomputer, signal
The costs such as reason circuit are relatively low, the simple device of control mode can increase the close of highway speed measuring point in the case of cost-effective
Degree, it is to avoid the generation of traffic accident.
Further, interrupting time set includes receiver and transmitter, and the receiver and transmitter are located at height respectively
Fast both sides of highway, and opposition setting.
Further, receiver uses photo resistance, and transmitter uses infrared transmitter.
Using two devices of receiver and transmitter, and highway both sides are separately positioned on, cost can reduced
On the basis of, more accurately measure the speed that automobile passes through.
Further, the travel speed detection means of light-duty vehicle, in addition to display, the display connects with single-chip microcomputer
Connect, the data processed result for showing single-chip microcomputer.Display is easy to check the overspeed situation of respective stretch, is easy to the section
Take measure further, the possibility that reduction traffic accident occurs.
Further, the travel speed detection means of light-duty vehicle, in addition to wireless base station apparatus, the wireless transmission dress
Put and be connected with single-chip microcomputer, for the data processed result of single-chip microcomputer to be sent to the server of relevant departments.Wireless base station apparatus
Be conducive to the monitoring of relevant departments, particularly traffic for violation vehicle and the punishment education to the driver.
Further, the distance between two adjacent measurement apparatus are between 20KM~40KM.
The present invention compared with prior art, has the following advantages and advantages：The present invention is adjusted using single-chip microcomputer, signal
Manage circuit, interrupt the better simply devices of relative inexpensiveness, control mode such as time set, in the case where reducing input cost
Refinement of testing the speed is pinpointed by of the prior art, the density that increase fixed point tests the speed further reduces the possibility of traffic accident generation.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is schematic structural view of the invention.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and exemplary embodiment and its explanation of the invention is only used for explaining the present invention, does not make
For limitation of the invention.
Embodiment
As shown in figure 1, the travel speed detection means of light-duty vehicle, including measurement apparatus, the measurement apparatus include according to
Single-chip microcomputer, signal conditioning circuit, the interruption time set of secondary connection, the interruption time set are used for the vehicle body length for detecting vehicle
The time by the position with vehicle body is spent, the single-chip microcomputer is entered by the length of wagon and vehicle of vehicle by the time of the position
Every trade sails velocity measuring.
Interrupting time set includes receiver and transmitter, and the receiver and transmitter are located at highway two respectively
Side, and opposition setting.
Receiver uses photo resistance, and transmitter uses infrared transmitter.
Also include display, the display is connected with single-chip microcomputer, the data processed result for showing single-chip microcomputer.
Also include wireless base station apparatus, the wireless base station apparatus is connected with single-chip microcomputer, at the data by single-chip microcomputer
Reason result is sent to the server of relevant departments.
The distance between two adjacent measurement apparatus are between 20KM~40KM.
