Embodiment
Embodiment one:
First, the utility model provides a kind of leakage inspector, comprise Photoelectric Detection module and water detection variable color paper, Photoelectric Detection module has the signal receiving end detecting variable color paper color change signals for receiving water, signal receiving end is in the face of water detection variable color paper, and Photoelectric Detection module also has the testing circuit processed described color change signals.Detect variable color paper by water and meet water meeting variable color, and it is different according to the ability of different colours reflection electromagnetic wave, after water detects the variable color of variable color paper, the electromagnetic wave reflexing to signal receiving end changes, no matter be grow or die down, testing circuit can detect this change, and Photoelectric Detection module just can judge whether leak.It is existing product that water detects variable color paper, patent documentation also has a lot, and the patents such as such as CN200610057305.1, CN200820057128.1, CN200820180041.3 and CN201420230775.3 all mainly teach relative production technique and the composition structure that water detects variable color paper.Because signal receiving end only needs in the face of water detects variable color paper, do not need to detect variable color paper with water to contact, therefore signal receiving end, testing circuit can be avoided to contact with leaking, make electric elements and leak mutually isolated, security performance is high, and do not need to carry out water-proofing treatment to electric elements, can reduce costs largely.
From the angle of more low cost, signal receiving end is infrared receiving tube D2, and Photoelectric Detection module also has infrared transmitting tube D1, and infrared transmitting tube D1 detects variable color paper in the face of water.And it is corresponding with infrared detection, the ultrared power change that testing circuit receives according to infrared receiving tube D2, cause the voltage at infrared receiving tube D2 two ends to change, therefore testing circuit is the voltage detecting circuit of the cathode voltage height change detecting infrared receiving tube D2.Such as water is white when detecting the drying of variable color paper, black is become after meeting water, the ultrared ability of black reflection is more weak than white, and the reflected signal strength therefore causing infrared receiving tube D2 to receive reduces greatly, thus causes the cathode voltage of infrared receiving tube D2 to occur to change largely.
And concrete voltage detecting circuit; the I/O port of single-chip microprocessor MCU can be connected to by the direct negative pole by infrared receiving tube D2 as shown in Figure 1; the cathode voltage height change of infrared receiving tube D2 is directly processed by single-chip microprocessor MCU; and draw result of leaking; the protection circuit of direct control product turns off, and prevents the situations such as product occurs short circuit, burn out because of leaking.
In addition also the cathode voltage signal of infrared receiving tube D2 can be amplified by comparer, as shown in Figure 2, the negative input of comparer P1 is connected with the negative pole of infrared receiving tube D2, the electrode input end of comparer P1 is connected with driving power, the output terminal of comparer P1 is connected to the I/O port of single-chip microprocessor MCU, can improve detection sensitivity like this.
The third mode is then as switching device by triode Q1, utilize the low and high level signal of comparer P1 output terminal to control triode Q1 conducting or to turn off the conducting or the shutoff that control corresponding protection circuit, as shown in Figure 3, the negative input of comparer P1 is connected with the negative pole of infrared receiving tube D2, the electrode input end of comparer P1 is connected with driving power VCC, the output terminal of comparer P1 is connected with the base stage of triode Q1, the grounded emitter of triode Q1, the collector of triode Q1 is connected with the coil side of relay R L1, the coil opposite side of relay R L1 connects driving power VCC, the contact series of relay R L1 is in protection circuit.Protection circuit is generally alarm and protection, short-circuit protection etc., and direct controlled loading also can be selected to have the major loop on/off of the product of leakage inspector.
Except infrared receiving tube D2 and infrared transmitting tube D1, signal receiving end also can adopt color detector or camera.Color shades after color detector can realize the change of water detection variable color paper chance water detects, and contrasts, just can draw conclusion of leaking with the color parameter after the chance water stored in system.Camera can to water detect variable color paper dry time and color after meeting water change carry out differential scan, then draw according to color distortion conclusion of leaking.The water of reversible color can be adopted to detect variable color paper, and namely water detects variable color paper and meets water meeting variable color, recovers original color again, can reuse, save cost after drying; Irreversible variable color, disposable water detection variable color paper can certainly be adopted.Color after color when water detection variable color paper is dry and chance water change also has no special requirements, and have two kinds respectively during general water detection variable color paper drying and after chance water and distinguish obvious color, being such as white during drying, is black or blueness etc. after meeting water.
