Parallel operation 7, and exported by multi-channel serial port converter 7 to microcomputer 9, touching is finally shown in by USB by microcomputer 9
It touches in the man-machine interface (attached drawing 4) for shielding 10, and then observes the variation of respective byte code value in " serial ports sink block ".It is logical
It is 16 road serial ports that 16 road serial converters 7, which are crossed, by the single channel serial ports expansion of microcomputer, and the road 1-8 is set as receiving by the present invention
Serial ports, 9-16 are set as sending serial ports, control so as to realize that 8 road serial ports send to receive with 8 road serial ports simultaneously.Serial ports is sent
Test is to send to instruct to handling controller 4 by microcomputer 9, since the code value of required transmission is identical, in attached drawing
Only need to be arranged one " serial ports transmission frame " in 4 man machine operation interfaces.Serial ports transmission may be implemented single channel and send with 8 roads simultaneously
It sends, is selected in the road 9-16 in " serial ports selection " frame in figure 4 all the way, and input to be sent out in " serial ports transmission frame "
The hexadecimal code value sent, clicking " single channel transmission " button can be realized the data transmission of the road serial ports；At " serial ports transmission frame "
The middle input hexadecimal code value to be sent, clicking " all sending " button can be realized the data transmission of 8 road serial ports, i.e.,
Microcomputer 9 sends serial ports instruction to 8 handling controllers 4 simultaneously.It is by control panel 5 or micro- that serial ports, which receives test,
The external inputs such as type computer 9 show data in serial ports sink block after the processing of handling controller 4.To realize certain road
Serial ports individual reception is tested and receives two kinds of functions of test simultaneously, certain may be selected all the way in setting in 4 man machine operation interface of attached drawing
Serial data receives and 8 road serial datas receive both of which simultaneously.After serial ports is connected, by selecting 4 human-machine operation circle of attached drawing
" serial ports reception " button all the way of certain in the road Mian Zhong 1-8 can monitor the reception data of certain serial ports all the way；It " is all connect by selection
Receipts " button is while receiving 8 road serial datas.
The method of the present invention implementation process is complicated, relates generally to five key steps: Preparatory work of experiment, parameter setting, serial ports hair
It send test, serial ports to receive test, stress test, wherein first carrying out room temperature test, carries out temperature stress experiment later.
Step 1: Preparatory work of experiment
1. system electrification: as shown in Figure 1 to system electrification, ac power plug 1 is connect
Logical 220v alternating current, presses power switch 2, detected respectively with multimeter two-way direct current power supply 3 output end whether
For+24V and+12V, and the switch of Multi-serial port converter 4 is set to open state.2. connecting equipment: the just common switching electricity of voltage tester
Handling controller 4 and test cabinet are attached by cable 11 by aviation plug 6.Transit cable 11 is the design of " 1 point 8 " formula, can
To connect 8 handling controllers 4 simultaneously, every handling controller 4 itself has 4 aviation plugs 6, is respectively as follows: power port, string
Row data port, two I/O data ports.It is arranged when connection by 4 number order of handling controller, to facilitate subsequent separate unit mould
Formula test.It is configured with test, the input terminal and output end voltage of voltage reduction module 3, network relay 5.
Step 2: parameter setting
After touch screen is shown normally, to computer " management "-" equipment manager "-com port serial communication baud
Rate is configured, and the road 1-8 serial ports is set as the road 38400,9-16 serial port baud rate and is set as 9600.Computer desktop CVI software is opened,
As shown in figure 4, corresponding serial port-opening serial ports-is selected to empty reception frame data.
Step 3: serial ports sends test
Corresponding hexadecimal data is inputted as shown in figure 4, sending in frame in serial ports, when progress separate unit handling controller 4
When test, the serial port (should be in 9-16 all the way) for selecting the handling controller to be connected is clicked " opening serial ports ", that is, is beaten
The transmission serial port currently selected is opened, " single channel transmission " button is clicked, i.e., the data sent in frame is sent to handling controller
4；When needing serial port 9-16 totally 8 road serial ports while when sending, sends and input the data to be sent in frame, click and " all send out
Send " button, then 8 road serial ports are sent simultaneously.
Step 4: serial ports receives test
As shown in figure 4, pressing corresponding key or rotation code-disc on control panel, then according to institute's instruction to be tested
It will receive hexadecimal data relevant to key command or code-disc instruction in serial ports sink block, after handling controller 4 is powered
Serial ports sink block will receive the data of the transmission of handling controller 4 automatically, each, which receives frame data, 4 rows 16 column, when pressing
Corresponding 16 system code value will change when a certain key.16 systems received according to the definition detection of each key command
Whether code is correct.
Step 5: stress test
After the completion of room temperature test, temperature stress circulation experiment is carried out, handling controller 4 is put into high-low temperature chamber, is arranged
The parameters such as " temperature cycle " of experimental box, " working time ", " cycle-index ", wherein " temperature cycle " represents high/low temperature circulation
Total time, " working time " represented within the entire temperature cycles period, the working time that handling controller 4 is powered on.It sets up and follows
After ring parameter, handling controller is powered up, and circulation step three, step 4 test content.
