Abstract
The utility model discloses a multi-channel gauge head sampling test device which comprises a tongue tube tester and a test bench. Wherein, the test bench is provided with 12 gauge head lead clamps, and a magnetic transmission device is arranged below each clamp. A hardware circuit in the tongue tube tester comprises a power supply module, an MCU micro controller, a tongue tube sampling module, an LED display module, a buzzer and a peripheral circuit thereof. A sampled signal is sent to a micro controller detection port through an optocoupler to be detected and compared by calculating the proportional relationship of all states and the actual proportional relationship so as to determine if the product is qualified; if the product is qualified, a system lights an LED lamp; if the product is unqualified, the LED lamp flashes; and 12 circuits can be tested simultaneously at one step.
Description
(1) technical field
The utility model relates to field tests, specially refers to a kind of hyperchannel gauge outfit sampling proving installation.
(2) background technology
At present, the known major part that is applied to water meter gauge outfit sampling apparatus is a tongue tube.Tongue tube is a kind of special key of magnetosensitive, and its two electric shocks are made by special material, are encapsulated in the glass tube of vacuum, as long as near it, two electric shocks of tongue tube will be pulled together, and make circuit turn-on with magnet, therefore tongue tube can be used as sensor usefulness, is used for counting, spacing etc.The principle of work of tongue tube is: when permanent magnet forms magnetic field near tongue tube or after by the energising on tongue tube reed is magnetized, the contact part of reed just is magnetized and induces opposite polarity magnetic pole, the magnetic pole of different name attracts each other, when the magnetic force that attracts surpassed the elastic force of reed, contact will adhesive; When magnetic force was reduced to certain value, the contact can be flicked by the elastic force of reed again.Operating resistance instability that tongue tube occurs in application process even overproof phenomenon cause product percent of pass only about 60%, and in view of the foregoing, the test of tongue tube is particularly important.Traditional manual testing's tongue tube adopts the multimeter resistance grade, and method of testing is as follows: two test pencils of multimeter are connected to respectively on two lead-in wires of tongue tube, and this moment, resistance value should be infinitely great.Near tongue tube, at this moment, the resistance of multimeter should be 0, and two reed ons of tongue tube are described with a fritter magnet, and after taking away small magnet, the resistance of multimeter should be got back to infinity again, and the tongue tube that meets above test phenomenon is certified products; If small magnet is near tongue tube, it is not 0 that multimeter shows, take away small magnet after, multimeter shows it is not infinitely great, such tongue tube just can not be used.But traditional manual testing's tongue tube measuring accuracy is low, efficient is low, and I spy of company develops the deficiency that a kind of hyperchannel gauge outfit sampling proving installation remedies desk checking for this reason.
(3) utility model content
The purpose of this utility model is to solve low, the inefficient present situation of manual testing's tongue tube precision, and a kind of tongue tube checkability height, check consistency is good, quality inspection is high hyperchannel gauge outfit sampling proving installation are provided.
The technical scheme in the invention for solving the technical problem is:
A kind of hyperchannel gauge outfit sampling proving installation is made up of tongue tube tester and test board.12 LED lamps, power light, relay indicating light are arranged on the described tongue tube tester.Be placed with 12 gauge outfit wire clamp on the wherein said test board, be placed with a magnetic drive device under each anchor clamps.Described magnetic drive device is made up of motor and magnet.The tongue tube tester is connected by power lead with test board.Wherein said tongue tube tester internal hardware circuit is by power module, MCU microcontroller, tongue tube sampling module, LED display module, hummer and peripheral circuit thereof.For the ability that guarantees the circuit acquired signal does not subtract and can not produce erroneous judgement, this circuit adopts dual power supply, and promptly one the tunnel is the sample circuit power supply, and one the tunnel is the data processing circuit power supply, thereby guarantees the accuracy measured.Power circuit is made up of magnetic bead RL1, RL2, RL3, RL4, miniature transformer U7, U8, electrochemical capacitor E1, E2, E3, E4, voltage stabilizing chip 7805, filter capacitor C1, C2, C3, C4, power light D0, resistance R 0.The MCU microcontroller is selected the magnificent chip 78E52B of nation chip for use, strong interference immunity, P0.0-P0.7, P2.4-P2.7 connects LED lamp control display interface, P1.0-P1.7, P3.0-P3.3 connects optocoupler the tongue tube signal is gathered, P2.2 controls hummer, principle of work of the present utility model and workflow are as described below: power on for the tongue tube tester, press start button, motor begins rotation, and (with the first passage is example, all like this with lower channel), magnet on the motor drives the magnet rotation in the gauge outfit, tongue tube is in random state in the gauge outfit, in the time of near the gauge outfit internal magnet goes to tongue tube, tongue tube is in attracting state, it is high level that microcontroller detects P1.0, the microcontroller T0 that picks up counting, when magnet during away from tongue tube, tongue tube is in off-state, it is low level that microcontroller detects P1.0, the T0 timing finishes and preserves, T1 picks up counting, in the time of near magnet goes to tongue tube once more, tongue tube is in closure state, and it is high level that microcontroller detects P1.0 once more, the T1 timing finishes and preserves, compare by proportionate relationship and the actual proportionate relationship that is provided with of calculating each state then, thereby determine whether product is qualified, if fruit product is qualified, then the LED lamp is bright, if product is defective, and then LED lamp flicker, all test the hummer that finishes for 12 groups and ring, remind the tester to exchange gauge outfit for so that carry out the test of next group tongue tube.
The beneficial effects of the utility model:
(1) a kind of hyperchannel gauge outfit sampling of the utility model proving installation can be tested the sampling of 12 road tongue tubes simultaneously, has avoided manual testing's drawback, has improved testing efficiency and measuring accuracy.
(2) a kind of hyperchannel gauge outfit sampling of the utility model proving installation adopts dual power supply, has avoided the interference of data processing circuit to sample circuit, has guaranteed the accuracy of test.
(3) a kind of hyperchannel gauge outfit of the utility model sampling proving installation circuit is simple, is easy to realize, can bright by LED (qualified) after every drive test examination finishes or LED glimmer (defective) differentiate the quality of tongue tube.
