[0042] Working principle:

[0043] The tension sensor 1 collects the tension data on the rivet gun, and the displacement sensor 2 collects the displacement data on the rivet gun. The two types of data are converted by the digital-to-analog converter 3 and sent to the MCU module 4. The MCU module 4 processes the data according to the user settings, determines whether the rivet is qualified, and sends a qualified / unqualified digital signal. The rivet gun and monitoring equipment can respond to this signal. At the same time, the data of this rivet will be sent to the external device through various protocols, and it can also be selected whether to be retained in the local storage card 8 according to the user's settings. When the external device is not connected or fails, the data will be automatically retained in the storage card 8 and uploaded the next time the external device is connected. In addition, this device can also act as a real-time digital-to-analog converter 3 to transmit the current sensor information to multiple platforms in real time.

The rivet data can be systematically analyzed in the background to improve the rivet gun.
