Module is by data information transfer to data reception module, and data reception module is by received data information transfer to data check list
Member；
Step 5: the data check unit for receiving data information first verifies data information, is mainly used for avoiding data
The loss or distortion of data information in transmission process, if verification failure, data check unit are transmitted to instruction module one feedback
Information, described instruction module convert command information for the feedback information received and are transmitted to by 232 communication interface modules
Control module, control module control bridge-type electrical resistance collection module and voltage or current acquisition module carry out Data Detection again, weight
The step of multiple step 3-5, until verifying successfully；
If verifying successfully, data check unit is by data information transfer to data fitting unit；
Step 6: data fitting unit will receive data information and carry out curve fitting algorithm process, obtain the reality of experimental data
Actual value is transmitted to data storage cell respectively and is stored, is transmitted to driver module by value, data fitting unit, is shown
Drive module is transmitted to display and is shown.
