When in use:
for the base module, the user horizontally places the base module, electrically connects the base module to an external power supply, and confirms whether the first correlation sensor 15 on the first circuit board 3 is in a correlation. For the tension meter module, the user observes whether the position of the indicator sheet 39 on the first pull tab 14 is aligned with the origin on the scale 11, if the position is not returned to the origin, the adjustment moving scale 11 slides up and down along the slide groove 28 on the housing 10, and finally the position of the indicator sheet 39 on the first pull tab 14 is aligned with the origin on the scale 11; for a slider system, the user selects the slide surface that needs to be in contact with the surface of the base module, say the first slide surface 44, the second slide surface 45 or the third slide surface 46, and then places the slider module over the first cover plate 6; then the user catches on the slider module with the drag hook 13, holds the pull ring 12 with the hand, then places the tensiometer level, pulls the tensiometer forward to pull the object forward motion together, this moment indicator 39 also slides on calibrated scale 11, reads the pulling force numerical value on from calibrated scale 11 and is the pulling force of pulling the object, this part is the pulling force value that the user observed.
When the user places the slider module on the base module, the second RFID card sensor on the second circuit board 5 below the cover plate can sense the information of the RFID card above the first cover plate 6, so that the sliding surface of the slider module can be identified to be in contact with the base module through the software background.
When the user adjusts the moving dial 11 to finally align the position of the indicator piece 39 on the first pull tab 14 with the origin on the dial 11, the second opposite-direction sensor on the third circuit board 18 determines whether the second groove 42 in front of the second opposite-direction sensor is blocked, and if not, the indicator piece 39 is aligned with the origin, so that whether the indicator piece 39 returns to the origin can be determined from the background.

When a user pulls the slider module by using the tension meter module, the slider module moves forwards, whether an obstacle exists in the front of the first correlation inductor 15 on the first circuit board 3 is continuously identified, the sliding distance and the sliding time of the slider module are identified by processing signals of the correlation sensors, and therefore information such as the sliding instantaneous speed, the sliding average speed and the sliding uniform speed of the slider module can be calculated.
Data of the tension meter module and data collected by a circuit board on the base module are transmitted to external equipment through cables to be stored and analyzed, real-time tension values of the tension meter can be judged through analysis of the external equipment, information such as displacement speed of the sliding block is judged, whether operation of an operator meets the specification or not can be judged, and whether operation of the operator is qualified or not can be judged. In a specific physical experiment examination, the corresponding experiment scores can be directly given to students on external equipment according to the operation of the students, and the real-time monitoring and intelligent scoring of the physical experiment mechanical device are realized.
On the operation display screen of external equipment, when the user operates the tensiometer module, the backstage can monitor real-time tension value in real time, the user sees the tension value of the external tensiometer with eyes, data input can be carried out on the operation display screen, the backstage can compare the tension value input by the user with the tension value obtained from the gravity sensor 22, and when the user operation is finished, the experimental score of the operation of the user can be given in real time according to the set scoring standard of the backstage of the external equipment. If the user disagrees with the score, the tension value in the operation process at that time can be called back on the external equipment, so that whether the score is judged by mistake or not can be judged through data monitoring.
When the tension meter is in a dead halt condition, the operation of resetting the circuit of the tension meter can be achieved by pressing the reset button 30 on the third circuit board 18 through the reset hole 29 with a sharp object.
