Description
Technical field
The utility model relates to a kind of vehicle driver place driving efficiency examination device, particularly checkout area and examines the sensor device that car tilts.
Background technology
According to Ministry of Public Security's " GA/T554-2008 vehicle driver place driving efficiency examination system " files specify, the accurate driver of motor vehicle must be able to waltz through " highly being that 8 centimetres, width are 20 centimetres monolateral bridge " and " highly being the continuous obstacle of cylinder pie of 70 centimetres of 6 centimetres, diameter "; Therefore judge whether the examination car goes up bridge and whether cake produced phenomenon such as to bump, wipe, roll be the indispensable function of a test system.For reaching this purpose, the method for taking now has two kinds, and a kind of is mechanical compression switch determining method, and the device that it adopts is to bury the dress mechanical switch on the monolateral bridge or on the cylinder cake in advance, and then adds a cover a hard cover plate of activity within the specific limits; Second kind is: the three dimension acceleration sensor determining method, the device that it adopts is to bury the dress three dimension acceleration sensor on the monolateral bridge or on the cylinder cake in advance, and then adds a cover a hard cover plate of activity within the specific limits.
Their common weak point is: 1, will be on the road surface underground feed cable and the signal cable buried underground, construction and maintenance all have big difficulty; The run time fault rate also can be higher; 2, will there be movable agency that can change the mechanical switch state or the movable device that conducts acceleration in monolateral bridge or cylinder cake surface, and are subjected to rolling of vehicle continually, have brought bigger difficulty for the manufacturing and installation; 3, because the wheel rim of wheel is not a rectangle, and the xsect of monolateral bridge is a rectangle, when car does not take turns to bridge floor but during flanging, also can press the movable agency that can change the mechanical switch state sometimes or information is being conducted to acceleration transducer, cause reporting by mistake the bridge conclusion; 4, because mechanical switch or acceleration transducer are mounted in below the movable agency, waterproof has been a problem of can not ignore, in case water inlet will certainly produce faults such as malfunctioning; 5, because structure causes installation and layout, same test item can only allow an examination car to be in the examination state, otherwise the result of mistake will occur; 6, be pressure switch because of what adopt, be not easy to determine its sensitivity that when adjusting too sensitively, the cart wheel light flips wiping will be changed state, be easy to the phenomenon of wiping bridge is thought by mistake be to have gone up bridge; Adjust too lately when blunt, bridge perhaps can not be identified and not think Shang bridge by mistake on the dolly.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of erecting equipment on the ground that need not is provided, install, field test automobile inclination sensor device easy to maintenance, this device is used for judging whether the examination car is gone up monolateral bridge and whether rolled phenomenons such as having gone up cake and have the accuracy of measurement height, reliable operation, can allow many to examine advantages such as car takes an exam simultaneously, to solve the problems referred to above that prior art exists.
The technical scheme that addresses the above problem is: a kind of field test automobile inclination sensor device, comprise the float level sensor that two structures are identical and two flexible pipes that connect two float level sensors, described each float level sensor comprises the device body of energy receiving fluids, in this device body and bottom the joint of being with external tooth is arranged respectively, two flexible pipes are socketed in respectively on the joint of two float level sensor device bodies and bottom to be tightly connected with the device body and constitute the linker that can hold certain liq, are perfused with liquid in linker, and leave certain no liquid space on linker top; Be separately installed with float on the liquid level of the device body of described two float level sensors, the upper inner of two level sensor device bodies be installed with respectively can the perception float whether approaching signal transducer with it, two connectors are separately fixed at the outside of two level sensor device bodies, and the signal of described two signal transducers is drawn by being fixed on two cables on the connector respectively.
The principle of work of field test automobile inclination sensor assembly of the present invention is: according to the linker theory, as two float level sensor I that constitute field test automobile inclination sensor device, when II is in same level, two float level sensor I, the float 12 of II device body inside, 22 can be on the surface level of sustained height, when float level sensor I position is higher than float level sensor II, float 22 in the float level sensor II device body is approach signal sensor 21 more, and when and even float level sensor I position was higher than float level sensor II certain altitude again and makes existing that signal transducer 21 can perception float 22, the output signal of signal transducer 21 had just reflected that float level sensor I is higher than float level sensor II and has reached a certain elevation.Vice versa.
During use, two float level sensor I of field test automobile inclination sensor device will be constituted, II is fixed on respectively on two different crossbeams of vehicle, and near the same surface level being in directly over the wheel shaft, so when on the pressure wheel of float level sensor I one side correspondence during monolateral bridge, the signal transducer 21 of opposite side float level sensor II device body inside will be exported and perceive the signal that float 22 exists, analyze this signal and just known that this moment, vehicle was in high low state on one side on one side, that is to say to have reached a certain degree of tilt, promptly on the vehicle monolateral bridge; In like manner, if vehicle has rolled cake, its vehicle body also is in certain degree of tilt, and the signal transducer of a certain side equally also can be exported a status signal.
Therefore, the field test automobile inclination sensor device that uses the utility model is as judging whether the examination car is gone up monolateral bridge and whether rolled the device of having gone up cake, it has following beneficial effect: 1, owing to be that two float level sensor I, II that will constitute field test automobile inclination sensor device install and fix near two different examining directly over car wheel of vehicle crossbeams on the scene respectively, connect with flexible pipe, on the scene the examining on the car of field test automobile inclination sensor device overall fixed, need not erecting equipment on the ground, therefore installation, easy to maintenance; 2, because the difference in height of two float level sensor I, II device body will reach certain bigger value the time, therefore the signal output that certain signal transducer on one side just has the perception float to exist measured and gone up monolateral bridge or roll the accuracy height of cake phenomenon, reliable operation; 3, owing to do not have complicated electronics or mechanical part thereby simple in structure, production and processing is convenient, and consistance is better, and integrated cost is very low; 5, because the device of each detection signal all on the examination car, forms definitely independently state, therefore same project can allow many to examine car and take an exam simultaneously, thereby has improved the utilization factor in examination hall.
Below, the technical characterictic to the field test automobile inclination sensor device of the utility model is further described in conjunction with the accompanying drawings and embodiments.
