Beneficial effect: the monolateral bridge examination of the utility model can judge accurately that with pick-up unit whether the examination vehicle is smoothly through monolateral bridge; Whether the pressure transducer on the monolateral bridge can pass through from monolateral bridge by perception examination car; That pressure transducer has is highly sensitive, can be under high temperature, severe cold outdoor environment advantage such as long-term uses, adopt module plug mounting means, easy to maintenance fast, bring economic benefit for the client.If the examination car falls down from monolateral bridge, the permanent magnet that is provided with on the ground, then monolateral bridge next door can trigger the Magnetic Sensor on the examination car, thereby judges that by vehicle-mounted industrial computer the examination car falls car.Permanent magnet high temperature, severe cold out of doors still is that rugged surroundings are used, and the Maintenance free maintenance is for the client practices thrift a large amount of maintenance costs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the user mode figure of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in Figure 1; Pick-up unit is used in a kind of monolateral bridge examination of the utility model; Comprise the vehicle-mounted industrial computer 1 that is installed in the car, adopt pluggable mode to be installed in the pressure transducer 2 on the monolateral bridge, as shown in Figure 2; Be separately installed with pressure transducer 2 on the bridge floor of illustrated two monolateral bridge first bridges, second bridge, and in the end of the bridge of Jia Qiao, second bridge, bridge and on the bridge floor at bridge tail three places, be separately installed with a pressure transducer 2.Pressure transducer 2 and 3 wireless connections of place appearance, the signal that pressure transducer 2 collects can radio to place appearance 3.Place appearance 3 links to each other with vehicle-mounted industrial computer 1 through vehicle-mounted appearance 4, and the signal of vehicle-mounted appearance 4 collection place appearance 3 is transferred to vehicle-mounted industrial computer 1 then.
A kind of monolateral bridge examination of the utility model also comprises with pick-up unit and is installed in ground permanent magnet 5; On the ground of relative second bridge one side of first bridge; Be between first bridge, the second bridge, be respectively equipped with one group of permanent magnet 5 in corresponding first bridge end of the bridge, the bridge and on the ground at bridge tail three places; On a side ground of the relative first bridge of second bridge, also be respectively equipped with permanent magnet 5 in corresponding second bridge end of the bridge, the bridge and on the ground at bridge tail three places.Described permanent magnet 5 installation sites respectively be installed in bridge floor on three pressure transducer 2 positions corresponding.Described permanent magnet 5 can trigger onboard sensor 6, and onboard sensor 6 links to each other with vehicle-mounted industrial computer 1 through signals collecting case 7.Described onboard sensor 6 is Magnetic Sensors, and onboard sensor 6 is provided with five, is installed in respectively on four wheels and bumper bar of examining car.
Described vehicle-mounted industrial computer 1 also be installed in control center in display screen 8, vehicle-mounted card reader receiving end 9 link to each other with audio-video collection equipment 11; Card reader receiving end 9 can receive the signal that the card reader transmitting terminal 10 that is installed in place next door sends.
