Driving switch sensor exports as two-way interlocking signal, and when namely a road is noble potential, another road is electronegative potential.When production testing, usually adopt oscillograph monitoring two paths of signals, and utilize the rotation of magnet steel change magnetic flux to make sensor that the exporting change of high electronegative potential occur, the angle that magnet steel rotates not easily reads, and detection efficiency is low.So make, a kind of degree of integration is high, the sensor detecting device of dependable performance.Easy to operate, compatible good.
Summary of the invention
The object of the invention is to develop a kind of novel gear position sensor pick-up unit, its principle of work is, single-chip microcomputer sends pulse to stepper motor, and stepper motor drives magnetic steel component to rotate change magnetic flux, makes sensor that the change of high electronegative potential occur.Send the output of sensor to single-chip microcomputer to process, judge sensor and magnetic steel component whether qualified.
For solving the problem, the present invention adopts following scheme:
A kind of driving switch pick-up unit, comprise the computer housing, Switching Power Supply, the single-chip microcomputer that arrange in the enclosure, single-chip microcomputer is connected by wire with Switching Power Supply, and is connected by data line with computer housing.Shell is provided with tooling base, tooling base is provided with column, stepper motor, rotor and zero graduation line, column and base adopt rivet, stepper motor is embedded in base, and is connected with rotor by transition gear, and rotor each several part also passes through rivet, there are three pilot holes rotor upper end, pilot hole has fastening screw, and there is index dial rotor lower end, has the through hole of sensor installation and the screw thread pin-and-hole of fixation of sensor above column.Shell is fixed be connected with computer housing display, aviation plug, power switch, at shelves pilot lamp, neutral indicatorlamp, digital display voltmeter, aviation plug one termination sensor, the other end is with Switching Power Supply, single-chip microcomputer, connect at shelves pilot lamp, neutral indicatorlamp.Digital display voltmeter connects with Switching Power Supply, and power switch connects with computer housing, display, Switching Power Supply, single-chip microcomputer.
Owing to have employed above technical scheme, the invention technological progress is as follows:
Present invention achieves detection during sensor production, simulate state during gear position sensor work completely, and accurately can measure the angle of magnetic steel component deflection, achieve sensor neutral gear and the output detections at shelves two paths of signals, and provide judgement to whether product is qualified.Single-chip microcomputer adds memory function, and stepper motor work one circulation, computer monitor can show detection data.
