Present invention uses some the more commonly used signal processing technologies, the signal of faint transient state amplified through gathering,
By comparing with normal voltage, output detections result.It is highly suitable for mid and low-end products.
This scheme largely solves the expensive price of legacy equipment and the operation of inconvenience, produces line employee and is easy to
Operation, owing to cost of manufacture is the lowest, installs simple, uses it is possible to line is produced in assembling quickly.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present invention.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the method for testing of the present invention comprises the following steps:
Step 1: small-signal is acquired；
Step 2: the signal collected is amplified；
Step 3: the signal after amplifying compares with normal voltage, obtains a result；Normal voltage is by several resistance phases
Deng divider resistance carry out dividing potential drop gained, every primary standard voltage is all equal difference；Signal after amplifying and all of standard
Voltage carries out voltage ratio relatively simultaneously, finally result of the comparison is shown by LED.By divider resistance is increased or decreased
Improve or reduce detection degree of accuracy.
The present invention is by faint collection, amplification, and by comparing with normal voltage after processing, obtains a result；Standard
Voltage is to carry out dividing potential drop gained by the divider resistance that several resistances are equal, and every primary standard voltage is all equal difference；To process
After signal and all of normal voltage carry out voltage ratio relatively simultaneously, finally result of the comparison is shown by LED, as
According to a definite sequence arrangement, LED will clearly be seen that the LED quantity that the signal of different capacity is lighted is different by fruit.Due to
Normal voltage is equal difference, it is possible to improve or reduce detection degree of accuracy by divider resistance is increased or decreased.
The signal of various kinds of sensors probe can be analyzed including audio signal, optical signal etc..Signal processing.
Weak current test (quiescent current):
It is frequently necessary to test quiescent current during electronic product test, testing weak signals method can be applied, by weak current
Signal is converted to LED instruction, judges whether to pass through according to specific requirement, so can reduce employee and fit the study of special equipment
Between Ying Shi, more can reduce erroneous judgement.
Faint infrared light strength test:
Infrared product typically requires and carries out intensity of illumination test, exists for conventional irradiance test instrunment and uses difficulty
Height, shows inconspicuous, and the problem that cost is high and plant maintenance is difficult, now by the method for testing weak signals, by infrared
The intensity of optical signal is shown by visible LED, well avoids a conventional test difficult problem, the survey of this simple low cost
Method for testing can well be popularized in factory.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
