Description
One, technical field
The utility model relates to measuring equipment, particularly a kind of stay-supported displacement transducer based on magnetosensitive angle technology.
Two, background technology
Traditional stay-supported displacement transducer adopts potentiometric displacement transducer, and it converts mechanical shift to by the potentiometer element resistance or the voltage output of linear with it or arbitrary function relation.Generic linear potentiometer and circular potentiometer all can be used separately as straight-line displacement and angular displacement sensor.But, be the potentiometer of realizing that the Displacement Measurement purpose designs, require between change in displacement and resistance variations, to have one and determine relation.The movable brush of potentiometric displacement transducer links to each other with testee.The displacement of object causes the resistance variations of potentiometer mobile terminal.The variable quantity of resistance has reflected the value of displacement, and the increase of resistance still reduces then to have shown the direction of displacement.Usually on potentiometer, pass to supply voltage, resistance variations is converted to voltage output.Resistance was that ladder changes with circle resistance when traditional stay-supported displacement transducer moved owing to its brush, and its output characteristics also is stepped appearance.If this displacement transducer is used as the Displacement Feedback element in servo-drive system, then excessive step voltage can cause system oscillation.Therefore in the making of potentiometer, should reduce the resistance value of every circle as far as possible.Simultaneously, another major defect of potentiometric transducer is easy to wear, and resolving power is poor, and resistance is on the low side, and high frequency characteristics is poor, thereby causes the decline of measuring accuracy.
Three, utility model content
At above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of stay-supported displacement transducer based on magnetosensitive angle technology, can effectively solve the loose contact of stay-supported displacement transducer, fragile, high frequency characteristics is poor, problems such as measuring accuracy difference, the technical scheme of its solution is, comprise wheel hub, transmission shaft and magnet, wheel hub are contained on the transmission shaft, and drive shaft cartridge is in the bearing of wheel hub both sides, wheel hub one side is equipped with the returning spring that links to each other with transmission shaft, transmission shaft one end is equipped with magnet, by the magnet outside data processor that matches and answer with magnet is housed, and the utility model is simple in structure, novel unique, easy to use, the measuring accuracy height, Mechanical Contact is good, life-span is good, poor reliability, high frequency response characteristic is good, by communication interface can be directly and application system carry out the exchange of data.
Four, description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a data processor structural frames diagrammatic sketch of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is elaborated.
Shown in Fig. 1,2, the utility model comprises wheel hub, transmission shaft and magnet, wheel hub 4 is contained on the transmission shaft 1, transmission shaft 1 is contained in the bearing 2 of wheel hub both sides, wheel hub 4 one sides are equipped with the returning spring 3 that links to each other with transmission shaft, transmission shaft 1 one ends are equipped with magnet 5, by the magnet outside data processor 6 that matches and answer with magnet are housed.
In order to guarantee result of use, said data processor 6 is that magnetosensitive angle inductor and the input/output module (device) by data processing unit (as microprocessors such as 80C51 single-chip microcomputers) both sides is connected to form through communication interface, magnetosensitive angle inductor places the input end by the data processing unit of magnet 5 one sides, and input/output module (device) places the output terminal of data processing unit opposite side; Said communication interface can be RS232 interface, RS485 interface; Said magnetosensitive angle inductor and magnet are installed on the same axis.
Working condition of the present utility model is, the steel cable of backguy is wrapped on the wheel hub, because of wheel hub and magnet link together, when backguy produces displacement, drive the rotation of wheel hub, the rotation of wheel hub causes the magnet that is connected with the axle of wheel hub to rotate, thereby the magnetic field of magnet produces the angle of a variation.When the backguy campaign took place, returning spring made backguy possess certain force of strain, guarantees the displacement of backguy and the proportionate relationship of magnetosensitive angle.Because of magnetosensitive angle inductor and magnet are installed on the same axis, effectively be used for the variation of induced magnet angle, and read the magnetosensitive angle information with microprocessor, be the displacement of backguy with the computing of magnetosensitive angle; Design communication interface, microprocessor receive by communication interface and return to application system from the order of application system and with displacement information by communication interface.
By above-mentioned situation as can be seen, the stay-supported displacement transducer that the utility model is based on magnetosensitive angle technology is transport vehicle with magnetic field, with the backguy displacement conversion is the magnetic field angle displacement, and displacement signal returned to application system by communication interface, when using, in order to improve measuring accuracy, change traditional stay-supported displacement transducer contact, easy to wear, shortcomings such as high frequency characteristics difference, stay-supported displacement transducer based on magnetosensitive angle technology is media with magnetic field, the mechanical shift variation is converted into magnetic field angle to be changed, the way of contact that solves the conventional pull wires displacement transducer on the one hand, wearing and tearing have been reduced on the other hand, improve the system high-frequency characteristic, thereby guaranteed the displacement detecting precision.The data processing operation device, being used for the magnetosensitive angle signal that receives is the displacement signal of backguy by the mathematical model computing.Communication interface, equipment by communication interface and application system communicates, reception feeds back to application system from the order of application system equipment and with the displacement signal that collects, and at work, eliminated Mechanical Contact, long service life, high frequency response characteristic are good, by communication interface can be directly and application system carry out the exchange of data, having improved data acquisition precision and stability and reliability, reduced the application threshold of displacement transducer, is the innovation of stay-supported displacement transducer.
It should be appreciated that, each parts of the utility model are the commercially available prod, contribution of the present utility model is, with them through science, reasonably combine, constitute a kind of novel stay-supported displacement transducer based on magnetosensitive angle technology, be effective to the displacement that testee produces, reach the purpose of measurement, above-mentioned only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, make a little changes or be modified to the equivalent embodiment of equivalent variations when the technology contents that can utilize above-mentioned announcement, be the content that does not break away from technical solutions of the utility model in every case, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
