[0026] Please refer to Figure 1 , Figure 1It is a schematic structural diagram of a controller provided by some embodiments of the present application. In this embodiment, the controller 100 provided by the present application may include, but is not limited to, a control circuit 110, an angle detection sensor 120, a level conversion circuit 130, and a display screen 140.

The level conversion circuit 130 is electrically connected to the control circuit 110 to convert the TTL level output by the control circuit 110 into an RS232 level, so as to be able to establish a communication connection with the tensile force measuring device 200. The tensile force measuring device 200 is used to measure the tensile force data of manually closing the vehicle tailgate.

[0028] Specifically, the angle detection device 120 can first convert the physical quantity corresponding to the obtained angle data into an analog signal, and then convert the analog signal corresponding to the angle data into a digital signal for output. The tensile force measuring device 200 can first convert the physical quantity corresponding to the obtained tensile force data into an analog signal, and then convert the analog signal corresponding to the tensile force data into a digital signal for output. The control circuit 110 receives the digital signals of the angle data and the tensile force data, and processes these signals at the same time, such as filtering, amplifying, etc. Then the processed signals are sent to the display screen 140. After receiving the digital signals sent by the controller 100, the display screen 140 will further process these signals to make them reach the display signals that meet the display requirements of the display screen 140, so that the user can intuitively view the angle data and the tensile force data of the vehicle tailgate on the display screen 140, thereby facilitating the user to analyze the tensile force change of manually closing the vehicle tailgate. Among them, the signal transmission between the control circuit 110 and the angle detection sensor 120 can be realized through the SPI bus. The signal transmission between the control circuit 110 and the display screen 140 can be realized through the I2C bus.
