Abstract
The utility model relates to a detection device, especially relates to an infrared detection device of a relay. The infrared detection device of the relay comprises a to-be-detected relay, a controller, an infrared emitter, an infrared receiver and a counter. The positive and negative poles of the controller are connected with the to-be-detected relay separately, the infrared emitter and the infrared receiver are arranged at the both sides of the to-be-detected relay contact respectively, and the counter is connected with the infrared receiver. By employing the infrared detection device of the relay, the man-made error is not only eliminated, meanwhile, a lot of manpower is saved, and a large-scale detection of the on-off times of the relay contact can be carried out.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of infrared detecting device of relay.
Background technology
Relay is a kind of of electric elements, a kind of components and parts of often using in the power supply field.Whether qualified the limit switch number of times of relay be to weigh relay quality major criterion.Before relay dispatches from the factory, to carry out limit test to the contact switch number of times of relay usually; At present for the test of the contact switch number of times of relay, the mode that common employing manually powers up, cuts off the power supply, gather the switch number of times of relay contact, this mode not only needs to expend great amount of manpower, and since the switch limit number of times of relay contact usually more than thousand times, therefore, on the human metering problem, there is certain error.
Summary of the invention
The purpose of this utility model provides a kind of infrared detecting device.By infrared detection, machine control pulse switch electricity, thus more efficient, the switch number of times of accurate busy relay contact.
The infrared detecting device of this relay comprises measured relay, controller, infrared transmitter, infrared remote receiver, counter; The positive and negative polarities of controller are connected with measured relay respectively, and infrared transmitter and infrared remote receiver are separately positioned on the both sides of measured relay contact, and counter is connected with infrared remote receiver.
Adopting the infrared detecting device of this relay not only to eliminate the people is the error of bringing, and simultaneously, has saved great amount of manpower, can test the relay contact switch number of times on a large scale.
Description of drawings
Fig. 1 is the circuit theory diagrams of relay infrared detecting device
Embodiment
As shown in Figure 1.The infrared detecting device of this relay comprises measured relay 3, controller 1, infrared transmitter 4, infrared remote receiver 5, counter 6, the positive and negative polarities of controller are connected with relay 3 respectively, and infrared transmitter and infrared remote receiver are separately positioned on the both sides of relay contact 2.Its principle of work is, the contact adhesive by thereby controller sends the pulse voltage trigger relay when the adhesive of contact, stops the infrared ray of infrared transmitter emission, from but infrared remote receiver can't receive infrared ray, when the pulse voltage disappearance, then open the contact, and infrared remote receiver will receive infrared signal once more, thereby formation one-period, whenever infrared remote receiver when this receives signal again, flip-flop number is once counted; In the time of can certainly adopting infrared remote receiver to can't accept infrared signal, counter is once counted at every turn.
Although the utility model here specifically describes in conjunction with the specific embodiments, but be understandable that this is illustration rather than restriction, under the prerequisite of the spirit of the present invention that does not break away from accessory claim and limited, in the scope of and accompanying drawing disclosed at preamble, it all is possible reasonably changing and revising.
