The implementation principle of the present embodiment are as follows:
When vehicle is carried out in the side that road is equipped with the first vehicle detection unit 1, the first vehicle detection unit 1 senses vehicle
And first detection signal is exported, after the first elevating mechanism 5 receives first detection signal, after the base stage access high level of triode Q1
Conducting, so that relay KM1 coil is powered, the first normally opened contact group of relay KM1 and the second normally opened contact closure, triode
Q1 is self-locking, and the coil of time-delay relay KT1 and the coil of time-delay relay KT2 are powered；So that first motor 56 is just
Turn current supply circuit conducting；First motor 56 works, and the rotating forward of output shaft drives the rotating forward of the first screw rod 55, the first screw rod 55
It rotates forward and the first sliding block 53 is driven to slide in first sliding groove 54 towards the first movable plate 51, thus driving 52 direction of the first pushing plate
The movement of first movable plate 51, when the first pushing plate 52 is moved towards the first movable plate 51, the second inclined surface 521 is along the first inclined surface
511 produce relative sliding, so that the first movable plate 51 of driving rises to and is above the ground level, so that the first weight sensing unit 3 can
It is in contact with wheel；
When vehicle is pressed on the first weight sensing unit 3, the first weight sensing unit 3 exports the first weight detecting signal, the
One processing unit 7 exports first control signal after receiving the first weight detecting signal, and first control circuit 72 receives the first ratio
Compared with exporting first control signal after signal；First prompt unit 8 exports the first standby signal after receiving first control signal；
That is: the resistance value of rheostat RP1 is adjusted in the minimum weight got on the car according to market, to form weight basis threshold voltage；
When there is vehicle by the first weight sensing unit 3, the weight that the first weight sensing unit 3 detects is higher than market and gets on the car most
When low weight, then the voltage value of the first weight sensing unit 3 output is higher than weight basis threshold voltage, then the high electricity of comparator A1 output
It is flat, it is connected after the base stage access high level of triode Q3, so that the coil of relay KM3 is powered, the normally opened contact of relay KM3
Closure, then 8 circuit of the first prompt unit is connected, and warning lamp L1 is lighted, to warn the vehicle for preparing to drive into from the road other side, road
The vehicle of Lu Zhongyou backward going；When not having, vehicle passes through the first weight sensing unit 3 or the first weight sensing unit 3 of process is
When the lesser bicycle of quality or motorcycle, what the first weight sensing unit 3 detected weigh less than, and that market gets on the car is minimum
Weight, then the voltage of the first weight sensing unit 3 output is lower than the voltage value of resistance R1 device, then comparator A1 exports low level,
It is not turned on after the base stage access low level of triode Q3, so that the first prompt unit 8 is without work, warning lamp L1 is not
It is bright；
Relay KM1 works after 10s, and time-delay relay KT1 is in running order, and the normally opened contact group of relay KT1 is closed
It closes, normally-closed contact group disconnects, so that the reversion current supply circuit of first motor 56 is connected, rotates forward current supply circuit and disconnects, output shaft
Reversion, drive the reversion of the first screw rod 55, the reversion of the first screw rod 55 drives the first sliding block 53 in first sliding groove 54 towards the
The sliding of one movable plate 51, so that the first pushing plate of driving 52 is moved backwards to the first movable plate 51, the first pushing plate 52 is backwards to first
When movable plate 51 moves, the second inclined surface 521 is produced relative sliding along the first inclined surface 511, thus the first movable plate 51 of driving
It slides under the effect of gravity to ground, to avoid the first weight sensing unit 3 by vehicle pressure.
When vehicle is carried out in the side that road is equipped with the second vehicle detection unit 2, the second vehicle detection unit 2 senses vehicle
And export the second detection signal；After second elevating mechanism 6 receives the second detection signal, after the base stage access high level of triode Q2
Conducting, so that relay KM2 coil is powered, the first normally opened contact group of relay KM2 and the second normally opened contact closure, triode
Q2 is self-locking, and the coil of time-delay relay KT3 and the coil of time-delay relay KT4 are powered；So that the second motor 66 is just
Turn current supply circuit conducting；The work of second motor 66, the rotating forward of output shaft drive the rotating forward of the second screw rod 65, the second screw rod 65
It rotates forward and the second sliding block 63 is driven to slide in second sliding slot 64 towards the second pushing plate 62, thus driving 62 direction of the second pushing plate
The movement of second movable plate 61, when the second pushing plate 62 is moved towards the second movable plate 61, the 4th inclined surface 621 is along third inclined surface
611 produce relative sliding, so that the second movable plate 61 of driving rises to and is above the ground level, so that the second weight sensing unit 4 can
It is in contact with wheel；
When vehicle is pressed in the second weight sensing unit 4, the second weight sensing unit 4 the second weight detecting signal of output, second
Processing unit 9 exports second control signal after receiving the second weight detecting signal, and second control circuit 92 receives second and compares
Second control signal is exported after signal；Second prompt unit 10 exports the second standby signal after receiving second control signal；That is:
The resistance value of rheostat RP2 is adjusted in the minimum weight got on the car according to market, to form weight basis threshold voltage；When
When the weight that second weight sensing unit 4 detects is higher than the minimum weight that market is got on the car, then the second weight sensing unit 4 is defeated
Voltage value out is higher than weight basis threshold voltage, then comparator A2 exports high level, after the base stage of triode Q4 accesses high level
Conducting, so that the coil of relay KM4 is powered, the normally opened contact closure of relay KM4, then 10 circuit of the second prompt unit is led
Logical, warning lamp L2 is lighted, and to warn the vehicle for preparing to drive into from the road other side, there is the vehicle of backward going in road；When not having
Having vehicle to pass through the second weight sensing unit 4 or pass through the second weight sensing unit 4 is the lesser bicycle of quality or motorcycle
When, the minimum weight for weighing less than market and getting on the car that the second weight sensing unit 4 detects, then comparator A2 exports low electricity
It is flat, it is not turned on after the base stage access low level of triode Q4, so that the second prompt unit 10 is without work, warning lamp L2
It does not work；
Relay KM2 works after 10s, and time-delay relay KT3 is in running order, the normally opened contact of time-delay relay KT3
Group closure, normally-closed contact group disconnects, so that the reversion current supply circuit of the second motor 66 is connected, rotates forward current supply circuit and disconnects, defeated
The reversion of shaft drives the reversion of the second screw rod 65, and the reversion of the second screw rod 65 drives the second sliding block 63 court in second sliding slot 64
It is slided to the second movable plate 62, so that the second pushing plate of driving 62 is moved backwards to the second movable plate 61, the second pushing plate 62 is backwards
When second movable plate 61 moves, the 4th inclined surface 621 is produced relative sliding along third inclined surface 611, thus the second activity of driving
Plate 61 slides to ground under the effect of gravity, to avoid the second weight sensing unit 4 by vehicle pressure.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
