In the present embodiment further include cooling system, the cooling system can be fan, for work in acquisition unit 1,
Power conditioning unit 2 and power supply unit 4 radiate.
Power supply unit 4 corresponds to power module, which is converted to DC28V for external power supply AC220V, for acquisition
Unit 1, power conditioning unit 2 and communication unit 5 are powered.
In the present embodiment, circuit-under-test unit is the PCBA board after waterproof coating film treatment, has 28 pieces, is divided into 4 groups,
It is connected by 28 road TCH test channels with system described in the present embodiment.Certainly, above-mentioned module, the number in channel are only institute of illustrating
With can be configured according to the actual situation in real work.
In the present embodiment, external power supply AC220V is converted to DC28V by power supply unit 4.Then pass through adjustment module 2.1
The power supply of DC28V is adjusted to the not unique predeterminated voltage of 4 road voltage values respectively.The voltage value of every road predeterminated voltage all 0~
The range of 27V.Then, 4 paths of adjustment module 2.1 by this 4 road predeterminated voltage by corresponding protective module 2.3 after, it is right
Switching module 2.2 should be transmitted to.Switching module 2.2 is again distributed 4 road predeterminated voltages one by one to 4 groups of TCH test channels.Every group of test
Channel corresponds to 7 pieces of PCBA boards.On the other hand, the 4 road predeterminated voltages that adjustment module 2.1 is converted to by voltage acquisition module 2.4
It is acquired；Then the 4 road predeterminated voltages that voltage display module 2.5 respectively collects voltage acquisition module 2.4 are shown
Show.The effect of voltage acquisition module 2.4 and voltage display module 2.5 is exactly that tester is allow intuitively to observe that 4 tunnels are pre-
If voltage value.
The voltage as needed for testing different types of PCBA board is different, in the prior art, every piece of PCBA
Plate can only be measured individually with a DC power supply.It is low to thereby result in testing efficiency.However, in the present embodiment, it can be simultaneously
28 pieces of PCBA boards are measured, the predeterminated voltage that every group of 7 pieces of PCBA boards receive is identical.So the method measurement that the present embodiment uses
It is high-efficient.
In addition, in the present embodiment, since external power supply AC220V is converted to DC28V by power supply unit 4, so tested
For PCBA board in acceptance test, generated test electric current can reach the rank of Naan.It is common straight in the prior art
Galvanic electricity source can only provide the test electric current of 10mA or more.Method used by the present embodiment can greatly improve measuring accuracy.
In the present embodiment, protective module 2.3 is provided between adjustment module 2.1 and switching module 2.2, i.e. power supply is protected
Protection circuit (fuse, fuse etc.).Such structure can greatly improve the safety of test method used by the present embodiment
Property.During the test, if a certain PCBA board has the damage on hardware, such as: component failure, short circuit, breakdown etc.,
The PCBA board will generate a very big test electric current after acceptance presupposition voltage.The test electric current is likely to result in described
The damage of test macro, so corresponding switching module 2.2 is provided to the circuit-under-test when above situation occurs in certain block PCBA board
The voltage value of unit (PCBA board) is zero, it is, corresponding power protecting circuit can disconnect first.
In the present embodiment, considering in economic cause is only provided with 4 road power protecting circuits, every group of PCBA board pair
Answer power protecting circuit all the way.When certain block PCBA board when something goes wrong, will disconnect 7 pieces of PCBA under same predeterminated voltage first
Plate.After investigation closes corresponding power protecting circuit again, continue to test.Certainly, during the test, more for pursuit
28 road power protecting circuits can be also arranged in high testing efficiency, can be in not shadow after above situation occurs in a certain PCBA board
It rings and carries out problem investigation under the situation of remaining PCBA board.
In the case where tested PCB A plate does not have hardware problem, after receiving corresponding predeterminated voltage, normal Naan is generated
Rank tests electric current.The corresponding amplification module 1.2 of the PCBA board can be amplified in real time the test electric current, obtain the PCBA
The real-time amplification electric current of plate.Tester, which can shift to an earlier date, is arranged threshold value in the monitoring unit 3 of computer, which passes through control
Module 1.1 is uploaded to corresponding comparison module 1.3.The real-time of the PCBA board is obtained in the corresponding amplification module 1.2 of the PCBA board
After amplifying electric current, which is compared by corresponding comparison module 1.3 with preset threshold, obtains the PCBA board
Real-time fiducial value.
Then the corresponding channel acquisition module 1.4 of the PCBA board by the real-time discharge stream of the PCBA board and real-time fiducial value into
Row acquisition, and it is uploaded to control module 1.1.Control module 1.1 carries out the real-time discharge stream of the PCBA board and real-time fiducial value
After analysis and processing, monitoring unit 3 is uploaded to by communication module 1.5 and communication unit 5.
Real-time discharge stream and real-time fiducial value of the monitoring module 3.1 according to upload, determine whether the PCBA board works normally,
Whether meet testing standard；
If the PCBA board is less than or equal to preset threshold in current real-time amplification electric current, show that the current PCBA board meets
Testing standard；
At this point, record the operating time of the PCBA board, i.e., tested duration；
Display module 3.2 shows the real-time current of the PCBA board, and real-time display according to the real-time value of magnification
The operating time of the PCBA board.
If the PCBA board is greater than preset threshold in current real-time amplification electric current, show that the current PCBA board is unsatisfactory for surveying
Test-object is quasi-；
It is instructed at this point, monitoring module 3.1 is sent by communication unit 5 and communication module 1.5 to control module 1.1, makes to control
Molding block 1.1 controls the corresponding zoom comparison circuit of the PCBA board and disconnects；Then monitoring module 3.1 stops recording the PCBA board
Operating time, and record the moment instantly；
Display module 3.2 is corresponding to prompt the PCBA board for abnormal operating state, and shows the corresponding amplification of the PCBA board
At the time of comparison circuit disconnects.
In the present embodiment, tester can be made to observe test process on computer display screen by display module 3.2.
Therefore every test index of PCBA board waterproof test can be directly displayed on computers, and monitoring unit 3 can be with
Above-mentioned test data is subjected to record storage.To which tester does not have to the test electricity of PCBA board during observing and measuring in real time
Stream；It is compared moreover, also not needing the artificial test electric current that will be observed that with threshold value.So the survey that the present embodiment uses
