The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can simplify the detection step, and detect separately at U-shaped sensor, thereby save detection time, improves the U-shaped sensor simple detection device of detection speed
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of U-shaped sensor simple detection device is characterized in that, comprises power supply unit, fault detect and indicating member and sensor linkage unit, and described power supply unit is composed in series by power supply V and power switch S;
Described fault detect and indicating member comprise the first current-limiting resistance R1, the second current-limiting resistance R2, the first light emitting diode D1 and the second light emitting diode D2, the described first light emitting diode D1 positive pole meets the described first current-limiting resistance R1, the described first light emitting diode D1 negative pole meets described power supply V, the described power switch S of described first another termination of current-limiting resistance R1, the described second light emitting diode D2 is in parallel with the described second current-limiting resistance R2, and the anodal and described power switch S of the described second light emitting diode D2 connects;
Described sensor linkage unit comprises first sensor interface 1, second sensor interface 2 and the 3rd sensor interface 3, described first sensor interface 1 is connected with the positive pole of the described first light emitting diode D1, described second sensor interface 2 is connected with the negative pole of the described second light emitting diode D2, described the 3rd sensor interface 3 ground connection.Wherein first sensor interface 1 is connected the I/O end of U-shaped sensor with second sensor interface 2, and the 3rd sensor interface 3 connects the earth terminal of U-shaped sensor.
The described first light emitting diode D1 is red light emitting diodes, is power light when not connecing sensor, is that sensor burns out pilot lamp when connecing sensor.
The described second light emitting diode D2 is green LED, and the on and off of green LED represent that U-shaped sensor does not block and blocks; Green LED bright and dark represents that U-shaped sensor advances the dust degree, and be more dirty, and lamp is just more dark, more clean, and lamp is just more bright.
Described power supply V is the 5V dry cell.
The beneficial effects of the utility model are: directly be connected with U-shaped sensor by linkage unit, no longer take the complete machine of the all-in-one of depositing and withdrawing in the testing process.There is the diode by red green two kinds of colors that indication is provided in addition, makes that the detection step is simple and visual result is understandable.
