Embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated to the utility model.
Please in the lump referring to Fig. 1 and Fig. 2, the Online Transaction Processing 100 that the utility model provides is used for the electrical property of on-line testing circuit board, and it comprises a time-sharing multiplex device 10 and an on-line testing instrument (ICT tester) 20.These time-sharing multiplex device 10 1 sides connect this ICT tester 20, and an other side connects respectively many measurement jigs 30.Every measurement jig 30 carries circuit board to be measured separately, and the quantity of these time-sharing multiplex device 10 concrete measurement jigs 30 that connect, calculate according to the operating efficiency of measurement jig 30, and it is suitable usually connecting 2～3.
This time-sharing multiplex device 10 comprises a processor 11, and a plurality of multi-channel switch 12.This processor 11 is an integrated chip, and it comprises an instruction queue and moderator 13, and a controller 14.
The common port 121 of this multi-channel switch 12 is connected to ICT tester 20, and multichannel end 122 is connected to measurement jig 30.In the present embodiment, the multichannel end 122 of two multi-channel switch 12 is connected to respectively the two ends of measurement jig 1, namely a moment, the passage of on-line testing instrument is connected to measurement jig 1, just can test the circuit-under-test plate on measurement jig 1.When the circuit-under-test plate on other measurement jig was tested, this multichannel end 122 can be controlled switching by this controller 14 and be connected to corresponding measurement jig.
The way of this multi-channel switch 12, select according to maximum quantity of the measurement jig 30 that connects that need, and each passage of on-line testing instrument will configure a multi-way switch.It can the relay system change-over switch, also can be the electronic type change-over switch.A plurality of these multi-channel switch 12 are arranged and are formed switch matrix.
This instruction queue and moderator 13, be used for receiving the start-up request signal from measurement jig 30, First come first served.When a measurement jig 30 is using ICT tester 20, instruction queue can preserve current request so, after current test is completed, then ICT tester 20 is switched to primary measurement jig 30 in current queue.When simultaneously two or many measurement jigs 30 sent test request, this instruction queue and moderator 12, according to certain rule, were queued up current request.And buffering can't dispensing request.
This controller 14 is also realized following the mutual of ICT tester 20, obtains the test result signal of ICT tester 20 and exports this test result.In the present embodiment, this Online Transaction Processing 100 also comprises that a fool proof alarm 40 is to carry out the differentiation of non-defective unit and defective products, this controller 14 exports test result to fool proof alarm 40 while obtaining test result, drive this fool proof alarm 40 with this and carry out fool proof work,, to prevent that the operator from putting into the non-defective unit district with defective products, perhaps non-defective unit is put into the defective products storage area.Preferably, this controller 13 also has at least one Long-distance Control connecting interface to connect external interface, and as network interface, serial ports etc., be transferred to far-end with the test mode of current device and test result.
Fig. 3 has provided the course of work of this time-sharing multiplex device 10.Any one of the measurement jig 30 that this time-sharing multiplex device 10 connects provides the startup request, after instruction queue and moderator 13 processing, 10 change-over switch matrixes of time-sharing multiplex device, and notify ICT tester 20 to start working, time-sharing multiplex device 10 enters the measurement jig duty.Until test finishes, time-sharing multiplex device 10 is received the test result signal of ICT tester 20, drives outside fool proof alarm 40, and switch matrix is resetted.Get back to idle condition., if the instruction of waiting in line is arranged in instruction queue, again start.Otherwise, rest on idle condition, wait for that enabled instruction next time arrives.
Id information that can the typing test product when this instruction queue and moderator 13 will be assigned in the right to use of ICT tester 20 measurement jig 30 wherein.This ICT tester 20 can use existing instrument, and its right to use comprises measurement circuit and test control signal.
The on-line testing instrument uses same test procedure,, according to control, in the same time the test product on different measurement jigs is not being tested.And the on-line testing instrument can not discovered current tool switching.
To sum up, time-sharing multiplex device of the present utility model is operated between ICT tester and measurement jig, many identical measurement jigs is connected to the ICT tester simultaneously gets on.But these several measurement jigs are that the ICT tester is used in timesharing, when whom take the ICT tester by, by the time-sharing multiplex device, according to the user, are operated to judge and switch.
Namely this time-sharing multiplex device provides following functions:
Obtain the test request of measurement jig; And formation is provided, process request;
The test request of all measurement jigs of ruling, be assigned to wherein one with the ICT tester right to use;
According to established rule, with all functions of ICT tester, switching is given and is obtained usufructuary measurement jig, comprises measurement circuit, test control signal etc.;
The signal of the tool of self-test in the future is delivered to the ICT tester.Comprise the id information of test product etc.;
After test finishes,, with the test result of ICT tester, pass to corresponding measurement jig;
With the test result storage, and by external interface such as network etc., be transferred to far-end;
The fool proof that connects alarm is provided, avoids the operator to obscure non-defective unit and defective products.
After any measurement jig is ready to, press start key, after the time-sharing multiplex device receives enabling signal, judge this signal is from which platform in the measurement jig that connects.And all ICT tester channel signals are switched on the measurement jig of current startup.After the passage switching is completed,, by the time-sharing multiplex device, to the ICT tester, send a signal that starts to test.The test procedure that the ICT tester brings into operation and programmed.
In the test procedure operational process,, if need to control measurement jig, also by the time-sharing multiplex device, be forwarded on corresponding measurement jig.
After test finished, the time-sharing multiplex device received the consequential signal from the ICT tester, was used for to operator's display measurement result.Can be used for controlling the fool proof alarm, and result is outputed on measurement jig.
By such design, can improve the service efficiency of ICT tester, can keep again each measurement jig can use all functions of ICT tester, also do not improve the cost of manufacture of measurement jig.In addition, being easy to can additional function.As the fool proof alarm, as Long-distance Control and supervision.
Above application specific case is set forth principle of the present invention and embodiment, should be appreciated that, above embodiment just is used for helping to understand the present invention, and should not be construed as limitation of the present invention., for one of ordinary skill in the art,, according to thought of the present invention, can change above-mentioned embodiment.
