Abstract
A kind of electronic signaling system of automobile speed limit is a kind of novel control of traffic and road system.It has solved at some un-reasonable phenomenon that installs and fixes speed limit alarm device on the vehicle and the often inoperative defective of common sign board has been set on road.The native system utilization has signal (sign) device of emission data capability, make vehicle in accordance with regulations speed travel the traffic hazard that causes because of hypervelocity with minimizing.
Description
The present invention relates to a kind of traffic safety device.A kind of electronic signaling system of automobile speed limit particularly.
Be to make order of the present invention vehicle by Dangerous Area as the intersection, the racing bend, numerous and diverse highway sections etc. remind the driver to slow down or maximum speed limit during with regulation speed limit highway section.
Order of the present invention ground can be realized by following measure: sender unit is installed in the place ahead in needs and regulation deceleration speed limit highway section.This device vehicle by the time send data such as speed limit, speed limit distance to vehicle.Being installed in receiving trap on the vehicle receives after the data its storage, demonstration.And these data and this car travelled speed and the stroke ratio during from this.In the speed limit distance range as overspeed of vehicle, circuit sound and light alarm then.And by control ignition systems for vehicles automatic speed-limiting.After vehicle sailed out of the speed limit zone, speed limit automatically terminated.
The drawing of accompanying drawing is described as follows:
Fig. 1 system works principle schematic
Fig. 2 emitter circuit block diagram
Fig. 3 receiving trap circuit block diagram
Fig. 4 emitter circuit theory diagrams
Fig. 5 receiving trap circuit theory diagrams
Describe working condition of the present invention in detail below in conjunction with accompanying drawing:
The electronic signaling system of automobile speed limit is made of the receiving trap two parts that are installed in the sender unit on the road and be installed on the automobile.Sender unit can be provided with data such as speed limit and speed limit distance with the dial switch of inside.Wherein the speed limit data can be changed at weather such as rain, mist, snow by sensor.The head that tests the speed of receiving trap, Control for Speed Limitation switch connect with automobile.Its speed, have the records of distance by the log and adjust consistent with the car speed table of having the records of distance by the log.This moment, system was ready.
When vehicle ' during to sender unit, the data of emitter emission are received device and receive.The prime amplifier of receiving trap is delivered to decoding scheme with the signal that receives through amplification, shaping filter, and decoding scheme becomes parallel data after serial data is deciphered, and delivers to register for low four, and Gao Siwei delivers to and can preset down counter.This moment is from the pulse signal of the head that tests the speed, and one the tunnel does subtraction counting to the speed limit distance parameter through being converted into behind the frequency division apart from the equivalent pulse in down counter.Another road is transformed into the aanalogvoltage that is directly proportional with speed through frequency/voltage (F/V).If vehicle travel does not reach the speed limit distance range, down counter is non-vanishing, and then down counter output keeps high level, and the control gate circuit is opened.Velocity voltage from F/V output compares comparer with the speed limit voltage of exporting from mould/number (A/D) converter around here.If car speed starts warning circuit by gate circuit and sends sound and light alarm greater than maximum speed limit comparer output high level then.The ignition circuit of Control for Speed Limitation switch disconnection simultaneously makes vehicle deceleration.When vehicle travel reaches the speed limit distance, the down counter counting is zero, and its output low level is closed gate circuit, speed limit release.
