Brief description of the drawings
Fig. 1 is structural principle block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in illustrative examples and the explanation of this utility model, but not as to restriction of the present utility model.
As shown in Figure 1: the utility model comprises photoelectric commutator, I/V converter, amplifier, A/D converter (as analog to digital converter of the present utility model), LCD display, central processing unit, LCD backlight driver, hummer, Laser emission driver, generating laser, infrared transmitter, infrared emitting driver, RAM storer, FLASH module, JATG interface and button, photoelectric commutator is successively by I/V converter, amplifier with after A/D converter, be connected with the photosignal input end of central processing unit, the audio signal output end of central processing unit is connected with hummer, the laser signal output terminal of central processing unit is connected with generating laser by Laser emission driver, the infrared signal output terminal of central processing unit is connected with infrared transmitter by infrared emission driver, the data storage end of central processing unit is connected with RAM storer, the optical frequency signal end of central processing unit is connected with FLASH module, the data communication end of central processing unit is connected with JATG interface, the control input end of central processing unit is connected with button, the display end of central processing unit is connected with LCD display by LCD backlight driver, and central processing unit adopts the single-chip microcomputer that model is MSP430F437, RAM storer and FLASH Module-embedding to central processing unit the function of data (realize stores meter calibration data and alarm threshold value arrange).
The utility model can be realized luminous power test, the bad test of light loss, buzzing warning function, fault location function, testing light source output function and backlight function, wherein, light loss be first using standard sources if testing light source is as with reference to performance number, then be connected in series testee (optical fiber link and fiber products) to photoelectric commutator of the present utility model, now optical loss test set can deduct the performance number reading the size of reference power value as loss value automatically.Loss value reading is less, illustrates that light loss is less, and the performance of tested object is better.Buzzing warning function: according to arrange power/exhaustion range as alarm threshold value, in the time of measured power, if reading is less than the power alarm threshold value being set, hummer can be sounded a buzzer automatically as alerting signal, throws fixed power bracket to remind this power of user to be less than.In like manner, if illustrate that this luminous power is within scope when the value of test is more than or equal to setting value.In the time of test light loss, if reading is more than or equal to the loss alarm threshold value being set, hummer can be sounded a buzzer automatically as alerting signal, to remind the loss of user's testee excessive.In like manner, if reading is less than the numerical value of setting, loss is within throwing fixed scope, and testee loss is little.Visual fault location function: launch the infrared light supply of 650nm, can macroscopic examination which goes out and overflow for there is red light in place being concatenated into after testee, overflow place in red light and illustrate to have and break or breakage problem.Testing light source output: can export 850nm, 1300nm, 1310nm, 1490nm and 1550nm wavelength light source, to provide the reference testing light source of testee to carry out the test of luminous power and light loss.Backlight function is applicable to user field and detects operation night.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
