Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the method flowchart of the preferred embodiment of the present invention.
Fig. 2 is the structural representation of the preferred embodiment of the present invention.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, below the present invention is described in detail.
As shown in Figure 1, a kind of detection method of the PCBA plate with NFC module, whether this method is normal for detection of the modules on PCBA plate (being module to be measured), first in step 10, on PCBA plate, CPU loads test procedure from removable memory interface, and on existing PCBA plate, CPU has just to power on and loads from removable memory interface the ability that has removable memory Program.Existing common removable memory interface comprises USB or SD card interface.
On PCBA plate, after CPU loading test procedure, can enter in step 20 module to be measured on PCBA plate is detected and generate testing result.On existing PCBA plate, have a plurality of modules (as FLASH module, memory modules, microphone module, horn module, communication module etc.), when on PCBA plate, CPU will test above-mentioned a plurality of modules, these modules are module to be measured, CPU is prior art to the detection method of these modules to be measured, as can be first write different data to each storage block of FLASH module or memory modules to the detection of FLASH module or memory modules, then read out and compare, if write when not identical with sense data, the testing result of FLASH module or memory modules is abnormal, otherwise be normal, as can be and detected whether there is this sound from microphone module by the sound in a fixed frequency of horn module broadcasting to microphone module and horn module, if do not had, the testing result of microphone module and horn module is abnormal, has normal, to the test of communication module, can and use communication module to carry out communication by initialization communication, if initialization communication are normal, communication module testing result be normal, otherwise testing result is abnormal.
Preferably, the concrete steps that generate testing result in step 20 are: it is initial value that testing result value corresponding to module to be measured is first set, when module to be measured detects when normal, it is normal value that testing result value corresponding to module to be measured is set, when module to be measured detects when abnormal, it is exceptional value that testing result value corresponding to module to be measured is set, and described initial value, normal value, exceptional value are different.Use initial value can know whether module to be measured is also in wait detection-phase, when reading normal value or exceptional value, illustrate that the detection of module to be measured is through with.
In order to facilitate the transmission of testing result, preferably, testing result is kept in a form, and can use the different units lattice in form to represent different modules to be measured.Testing result can be stored in volatile memory (as RAM) or nonvolatile memory, residual for fear of testing result, and preferably, testing result is kept in RAM.
Then enter in step 30 CPU on PCBA plate testing result is sent to NFC information acquisition platform by NFC module.NFC information acquisition platform can receive testing result, and in step 40, NFC information acquisition platform shows testing result.NFC information acquisition platform has multiple implementation, simply can realize the collection of testing result and demonstration for a computer connects a NFC module, and can be also the panel computer with NFC module.Tester can see this testing result, if testing result is all normal, just can assert that PCBA plate is normal, if certain module in testing result is abnormal, can carry out mark to this module, so that maintenance.
Impact for fear of mark on PCBA plate outward appearance, in the time of can entering step 50NFC information acquisition platform and the information that testing result comprises out of order module to be measured detected, prints the information of the module to be measured of fault.Print rear available noresidue and be adhesive on PCBA plate, easy access.
And the present invention also provides a kind of detection system of the PCBA plate with NFC module, for detection of PCBA plate 3, on PCBA plate 3, with CPU31, NFC module 32 and removable memory interface 33, CPU31 is connected with removable memory interface 33 with NFC module 32.This detection system comprises NFC information acquisition platform 1, removable memory 2, and NFC information acquisition platform 1 comprises NFC communication unit 11 and information acquisition display unit 12, and NFC communication unit 11 is connected with information acquisition display unit 12.Wherein, removable memory 2 is connected for the removable memory interface 33 with PCBA plate 3; NFC communication unit 11 for PCBA plate 3 on NFC module 32 carry out communication; Information acquisition display unit 12 is for being gathered the testing result of PCBA plate 1 and shown testing result by NFC communication unit 11.Common removable memory 2 is USB flash disk or SD card.Common information acquisition display unit 12 is computing machine.NFC communication unit 11 is also a NFC module.
When this detection system of application is carried out PCBA plate 1 while detecting, removable memory 2 is connected with removable memory interface 33, NFC communication unit 11 and NFC module 32 is mutually close, the test procedure that CPU31 can load on removable memory 2 detects the module to be measured of PCBA plate 1, and testing result is sent to NFC information acquisition platform 1 by NFC module 32, the information acquisition display unit 12 of NFC information acquisition platform 1 receives rear demonstration testing result, when information acquisition display unit 12 is computing machine, testing result will show on the display of computing machine.
Further, this detection system also comprises a printer 4, and printer 1 is connected with information acquisition display unit 12, and printer 4 is for printing the failure message of testing result.When information acquisition display unit 12 detects while including failure message in testing result, at printer 4, print the failure message in testing result.
To sum up, when use the present invention carries out with the detection of the PCBA plate of NFC module, can complete time saving and energy savingly.
Although more than described the specific embodiment of the present invention; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present invention; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present invention, all should be encompassed in the scope that claim of the present invention protects.
