Description
Technical field
The utility model relates to a kind of electron device checkout equipment, refers in particular to a kind of proximity Hall switch fault detector.
Background technology
Hall element is a kind of magneto sensor.The switch that utilizes Hall element to make is called Hall switch.When the magnetic object shifted near Hall switch, the Hall element on the switch detection faces changed the switch internal circuit status because producing Hall effect, and near the object that is magnetic the identification thus exists, and then the on-off of gauge tap.Be welded at present each anchor clamps of factory's production line, produce pipeline and use in a large number the Hall-type approach switch, in order to respond to the laying state of automobile body part on anchor clamps, and carry electric signal to carry out next step action to relevant device, when faults such as the Hall-type approach switch open circuit, existing detection method is for carrying out short circuit with approach switch output, input lead, then judge by PLC display screen demonstration data whether approach switch is normal, needing 2 people to cooperate fulfils assignment, and deterministic process is complicated, length consuming time affects the production line normal running speed.China Patent Publication No. CN2901332Y, open day on May 16th, 2007, name is called in the utility model patent of " circuit trouble shooter " and discloses a kind of circuit trouble shooter, comprise housing and be installed on the interior fault detection module of housing, the input end of voltage transformation unit links to each other with extraneous power supply in the described fault detection module, and the output terminal of voltage transformation unit links to each other with the input end of rectification unit; The output terminal of rectification unit is divided into two-way, and the relay of leading up to links to each other with detecting unit, and another road links to each other with relay by filter unit and oscillating circuit unit, and delay unit is connected between filter unit and the oscillating circuit unit; Described detecting unit comprises the two-way detection line, and an end of two-way detection line links to each other with two adhesive switches of relay, and the other end of two-way detection line links to each other with signal live wire L3 and circuit L4 to be measured respectively.This utility model is applicable to the electric circuit inspection of 220V civil power, and is not suitable for the detection of Hall-type approach switch, and testing circuit is comparatively complicated.
The utility model content
The purpose of this utility model is the fault detection method defective of very complicated comparatively that overcomes proximity Hall switch in the prior art, and a kind of whether normal proximity Hall switch fault detector of proximity Hall switch of can fast detecting judging is provided.
The purpose of this utility model is to be achieved by following technical proposals:
A kind of proximity Hall switch fault detector, comprise direct supply, the direct supply anode is connected with the first pilot lamp, the direct supply negative terminal is connected with the second pilot lamp, the first pilot lamp two ends are respectively equipped with the first port and the 3rd port that connects proximity Hall switch, the second pilot lamp two ends are respectively equipped with the second port and the 4th port that connects proximity Hall switch, and the first port and the second port are near power end.This circuit is applicable to the fault detect of three line proximity Hall switchs: three line proximity Hall switch both positive and negative polarities connect respectively the first port and the second port, when three line proximity Hall switchs are output as timing, output termination the 4th port, at this moment, iron block touches three line proximity Hall switchs, if the bright three line proximity Hall switchs that then represent of the second pilot lamp work, if going out, the second pilot lamp represents that then three line proximity Hall switchs break down; When three line proximity Hall switchs are output as when negative, output termination the 3rd port, at this moment, iron block touches three line proximity Hall switchs, if the bright three line proximity Hall switchs that then represent of the first pilot lamp work, if going out, the first pilot lamp represents that then three line proximity Hall switchs break down.
As a kind of preferred version, also be in series with a resistance R between direct supply anode and the first pilot lamp.If detect the two wires proximity Hall switch, this must connect pull-up resistor R, two terminals of two wires proximity Hall switch this moment connect respectively the first port and the second port, when iron block touches the two wires proximity Hall switch, the bright two wires proximity Hall switch that then represents of the pilot lamp of proximity Hall switch self works, and the pilot lamp of self goes out and represents that then the two wires proximity Hall switch breaks down.
As a kind of preferred version, direct supply is 16 volts-20 volts.16 volts-20 volts is that the proximity Hall switch optimum operating voltage is interval.
As a kind of preferred version, the resistance of resistance R is 25 ohm-30 ohm.
The beneficial effects of the utility model are, whether fault detector can fast detecting be judged proximity Hall switch and broken down, and this detector arrangement is simple, is easy to realize, easy to operate.
