Referring to Figure 10, be a kind of schematic flow sheet of testing the method embodiment one of electronic product serial ports provided by the invention.
Need to prove that the method for the test electronic product serial ports that the embodiment of the invention provides is realized by the disclosed frock of previous embodiment, may further comprise the steps:
Step 100 scans the interface that is connected between frock and the electronic product to be measured, discerns the pattern of said frock;
Step 101 recognizing said frock when being prepattern, is controlled said frock and is connected with PC, and mark off address space, receives the detecting information that is used to test the electronic product serial ports that said PC writes to said address space;
Step 102 is recognizing said frock when being test pattern, controls said frock and said PC and breaks off, and utilizes said detecting information that the electronic product serial ports is tested, and stores said test result data;
Step 103 recognizing said frock when being the data query pattern, is controlled said frock and is connected with said PC, and the test result of said storage is sent to said PC.
When the electronic product serial ports was tested, this frock can also show the model and the test result of electronic product;
When the test of electronic product serial ports was accomplished, this frock can also be sent alerting signal indication test result.Can serve as unusual for example, show that green indication test result is normal with pilot lamp exhibit red indication test result; Perhaps ring with hummer and indicate for one test result normal, hummer hurriedly rings many, and the indication test result is unusual; Perhaps normal with the bright indication test result of pilot lamp, send rapid chimes of doom with hummer and represent that test result is unusual.
Below will describe the method flow that utilizes frock provided by the invention to test in detail.
At first, the main control module of frock passes through 4 serial ports of the continuous scan interface module of serial port module,
When on the PC interface (being COM1) in scanning the interface that is connected between said frock and the electronic product to be measured exchanges data being arranged; The serial port module stops the scan interface module; Analog channel is fixed on the COM1 position; This moment, frock was in prepattern or data query pattern, controlled said frock and communicated with the PC that is connected on this PC interface.Need to prove that frock is through the instruction of identification PC interface COM1, distinguishing present mode is prepattern or data query pattern.Prepattern was a frock before test electronic product serial ports to be measured, and the detecting information with all electronic product serial ports to be measured sends to frock in advance; The data query pattern is to check the test result of surveying the electronic product serial ports.If prepattern, PC then presets detecting information to main control module, and main control module then distributes address space in memory module, and detecting information is write in the memory module addresses distributed space.These detecting informations comprise: " the ready signal " of " model code " of product to be measured, product to be measured, and to " answer signal " of " test instruction " of product to be measured, product to be measured.
If the data query pattern, then PC then sends the data query request to main control module, and main control module then reads the test result data of memory module, and test result data is sent to PC.This test result data comprises: the model of product to be measured, bar code information, quality state (normal or unusual).
Main control module is through 4 serial ports of the continuous scan interface module of serial port module; When the bar code scan interface (COM2) that detects interface module when exchanges data is arranged; The serial port module stops to scan PC interface COM1; Single step is switched at COM2 and product interface COM3 to be measured (perhaps COM4), and the pattern of this moment is a test pattern, and frock is broken off with the PC that is connected on this PC interface.
In the time of below will describing frock in detail and be in test pattern, the method flow that the electronic product serial ports is tested.Shown in figure 11, the method flow that present embodiment provides comprises:
Step 201 compares the bar code information of the bar code information that reads and said frock storage; If bar code information is inconsistent, show that then this electronic product serial ports is for the first time to be tested, need then change step 202 over to for its memory allocated space; If consistent, prove that the detecting information of the electronic product serial ports to be measured that this bar code information is corresponding has been kept in the memory module, this electronic product serial ports to be measured needs test again, need not redistribute new storage space, directly changes step 203 over to;
Step 202 when inconsistent as if bar code information, is the corresponding electronic product serial ports memory allocated to be measured space of this bar code information.
Step 203 receives " the ready information " of electronic product to be measured;
Step 204 compares said " ready information " and " the ready information " that originally was stored in the frock, obtains the entry address, from the detecting information of frock storage, obtains test instruction and corresponding answer signal according to this entry address;
Step 205 is sent the test instruction that gets access to electronic product serial ports to be measured;
Step 206 receives the answer signal to said test instruction that the electronic product serial ports returns;
Step 208 will write the storage space that memory module is distributed to the corresponding test result data of the test result of electronic product.
At last, if test is unusual, the hummer of frock sends rapid " tick and drip " chimes of doom; If test is normal, the hummer of frock is sounding not, and pilot lamp is bright.
The embodiment of the invention provides the method with frock test electronic product serial ports, because this frock integrates realization with each module, than testing with PC; Its volume is littler; Taking up room is convenient for carrying for a short time, and because before the test electronic product, just detecting information is downloaded to from PC the memory module of frock, therefore in test process; Need not be connected with PC; Reduced the probability and the time that are connected with PC, effectively avoided in test process, the damage that the PC serial ports is caused because of hot plug or sudden power.
One of ordinary skill in the art will appreciate that all or part of flow process that realizes in the foregoing description method; Be to instruct relevant hardware to accomplish through computer program; Described program can be stored in the computer read/write memory medium; This program can comprise the flow process like the embodiment of above-mentioned each side method when carrying out.Wherein, described storage medium can be magnetic disc, CD, read-only storage memory body (Read-Only Memory, ROM) or at random store memory body (Random Access Memory, RAM) etc.
The above is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also are regarded as protection scope of the present invention.
