Abstract
An alarm for displaying the load of a vehicle provides the digital references of safe driving for avoiding peccant overload and reducing traffic accidents. The utility model uses a cable linear displacement transducer to transfer the compressed displacement of front, back, right and left steel spring plates of a loaded vehicle to a wire wheel through a non-linear potentiometer in the cable linear displacement transducer; the machinery rotation of the wire wheel drives an electric brush to rotate to change resistance value; the variation signals of the resistance value are inputted into a display device to carry out the alarm for digitally displaying the load.
Description
The utility model belongs to the electronic instrument field.
Prototype of the present utility model is that spring balance is after adding constant weight on the spring balance, spring stress compresses, by scale numerical value shown on the spring balance as can be known how many utility model of weight according to the spring balance principle a kind of vehicle load display alarm has been proposed.
The purpose of this utility model has provided a kind of vehicle load displaying alarm, vehicle is when shipment, because vehicle itself does not have the load-carrying Displaying Meter, how much shipment weight is, whether overload and all feel unsure of, for fear of overload violating the regulations, reduce traffic hazard, for safe driving provides digit basis.
The technical solution of the utility model is: the displacement of the steel spring plate of the fourth officer all around pressurized after utilizing the cable type linear movement pick-up with vehicle load, by the function generating potentiometer in the cable type linear movement pick-up, mechanical drive by wire wheel, drive the brush rotation and change resistance value, the variation signal input display of resistance value carries out the display alarm of load-carrying numeral.
The cable type linear movement pick-up is fixed on the vehicle crossbeam of every auxiliary spring steel plate top, and the fixation with steel wire of cable type linear movement pick-up is on steel spring plate.Behind the vehicle stand under load, the relative distance between crossbeam and steel plate shortens, and makes the also corresponding shortening of steel wire length of cable type linear movement pick-up, reaches the purpose of measurement, and the potentiometer design of Windings becomes non-linear, and is consistent with the variation of steel plate.
The measure portion of instrument adopts unbalanced bridge to return to zero and the ratio range is regulated.Because directly the variation of measuring resistance is difficult to make the potentiometer resistance value of fourth officer steel plate all to be adjusted at zero-bit, so, regulate zero-regulator resistor when vehicle is unloaded and make bridge balance with the resistance of tested potentiometer and two arms of zero-regulator resistor formation electric bridge.In addition because the total value that is difficult to potentiometer resistance is changed just in time is the dead weight capacity of steel spring plate, and the steel plate characteristic of same each car of vehicle is always variant, different automobile types more can't be general, so the terminal voltage of electric bridge is regulated in design, can change the range of electric bridge, regulate by adopting the ratio range to regulate applicable to the range of different automobile types.The A/D interface circuit is sent in the current potential output of electric bridge, and instrument adopts 7107 general large scale integrated circuits to make the A/D interface circuit, carries out numeral by LED and shows.When overload of vehicle, the bright part of instrument numeral stroke is electronegative potential, and input rejection gate current potential also is electronegative potential, and rejection gate is output as noble potential, is at this moment reported to the police by light emitting diode.Metering circuit, display circuit, warning circuit design on a bar printing plate.
Advantage of the present utility model: highly versatile, the vehicle (comprising train) that is applicable to various tonnages can be made into electronic instruments such as overspeed alarm, overtemperature alarm simultaneously because instrument adopts the general digital circuit.
Accompanying drawing 1 is the front view of cable type linear movement pick-up of the present utility model.
Accompanying drawing 2 is installation site of the present utility model synoptic diagram.
In the accompanying drawing 11 is wire wheel, the 2nd, and cable type linear movement pick-up shell, the 3rd, potentiometer winding, the 4th, function generating potentiometer, the 5th, potentiometer shaft, the 6th, potentiometer brush, the 7th, spring recovering mechanism, the 8th, wire rope.
In the accompanying drawing 29 is cable type displacement transducers, the 10th, and steel spring plate, the 11st, vehicle crossbeam, the 12nd, display.
Provide an embodiment of the present utility model below in conjunction with accompanying drawing:
After the vehicle carrying, relative distance between steel spring plate 10 and the vehicle crossbeam 11 shortens, the also corresponding recovery of wire rope 8 length of cable type linear movement pick-up 9 is shortened, because the effect of spring recovering mechanism 7, wire wheel 1 rotates to an angle, potentiometer shaft 5 drives brush 6 rotations simultaneously, reaches the purpose that changes resistance value, and the variation signal input display 12 of resistance value carries out the display alarm of load-carrying numeral.
Claims (2)
1, a kind of vehicle load of being made up of sensor, display shows warning horn, it is characterized in that sensor installation on vehicle spring steel plate.
2, vehicle load display alarm according to claim 1 is characterized in that sensor is the cable type linear movement pick-up.
