Device 1 is connected with rear end warning sign 3, and the top of warning sign 3 is equipped with LED 12 and electrically driven (operated) sound as caused by solar panel 5
Light crossing-signal, audible-visual annunciator are made up of loudspeaker 9 and LED charactrons 10, when no vehicle 8 by when, by controlling AT89C5l
11 points of single-chip microcomputer gives a green light 12, and when vehicle 8 is by the coil, the irony with vehicle sheet will change the magnetic flux in coil,
Causing the change of wire loop inductance value, change of the speed measuring device 4 by detecting the inductance value obtains different signals, and letter
Number it is delivered to by signal wire in AT89C51 single-chip microcomputers 11, vehicle speed is calculated using following formula 1 by Coil Detector
Degree, vehicle program is calculated by the lay-by time by following formula 2, then by controlling AT89C5l single-chip microcomputers 11 will
Vehicle 8 is expected the time showing by lay-by on charactron 10, and simultaneously by controlling AT89C5l single-chip microcomputers 11 to make loudspeaker
9 work.
Inductance coil detection method be specially：The detection of twin coil is to set two respectively in the rear and front end of lay-by
Sensor 1, and two sensors 1 are provided with a certain distance, as shown in the explanation accompanying drawing 2, it is assumed that the lay-by of road away from
From for S, the two sensorses 1 of road one end are at a distance of S ', and the time that vehicle 8 reaches first sensor 1 in one end is Ta, vehicle 8
The time for reaching another sensor 1 in one end is Tb, and speed measuring device 4 measures vehicle 8 and is by the speed of one end two sensorses 1
V,
V=S '/(Tb-Ta) formula 1
