The electric wrench 3 outputs a torque signal to the signal processing control unit 1 in real time, the signal processing control unit 1 processes signal data of the input torque signal, and an output control signal is transmitted to the electric wrench 3 through the controller 2 to output a driving signal, so that the accurate control of the tension of the parking brake cable is realized; the handle operating mechanism 4 outputs the rotation angle signal and the torque signal of the parking brake handle to the signal processing control unit 1 in real time, and the signal processing control unit 1 processes the input rotation angle signal and torque signal, and then outputs a control signal to the handle operating mechanism 4 through the controller 2 to output a driving signal, so as to realize accurate control of the rotation angle and the rotation angle of the parking brake handle.
In this embodiment, the signal processing control unit 1 is a control center of the system, and performs analog-to-digital conversion and data processing on a torque signal input by the electric wrench 3 and a rotation angle signal and a torque signal of the parking brake handle input by the handle operating mechanism 4, and then outputs a control signal to control the electric wrench 3 and the handle operating mechanism 4 through the controller 2, so as to realize automatic and accurate adjustment of the parking brake. The controller 2 outputs a high-current driving signal (such as a Pulse Width Modulation (PWM) pulse signal) meeting the requirement according to the control signal output by the signal processing control unit 1 to drive the electric wrench 3 and the handle operating mechanism 4 to move. When the electric wrench is in operation, the electric wrench 3 is sleeved on the parking brake cable adjusting nut, and the tension of the parking brake cable is adjusted by tightening and loosening the nut; the handle operating mechanism 4 acts like a mechanical arm and is firmly contacted with the parking brake handle to replace a human hand to operate the handle.
According to the embodiment, the parking brake cable adjusting nut is adjusted through the electric wrench 3, so that the tension of the cable can be automatically adjusted, and the tightening operation of a hand-held electric gun of a worker in a traditional method is replaced; by providing the handle operating mechanism 4 to operate the parking brake handle, the operation of manually pulling up and putting back the parking brake handle by a worker in the conventional method is replaced. By outputting the torque signal of the electric wrench 3 and the rotation angle signal of the parking brake handle and the torque signal to the signal processing control unit 1 in real time, the accurate control of the tension of the parking brake cable and the torque and rotation angle of the parking brake handle is realized.

The embodiment provides a technical scheme of the electric wrench 3: mainly comprises a first driving motor 31 for providing power and a sleeve 34 for rotating a parking brake cable adjusting nut. Because the motor rotation speed is high, the first driving motor 31 cannot directly drive the sleeve 34, and the first speed reducer 32 needs to be arranged to reduce the speed, so that the sleeve 34 rotates slowly. In order to output the torque signal of the electric wrench 3 in real time, a first torque sensor 33 is provided on the output shaft of the first speed reducer 32, and an electric signal representing the magnitude of the torque is output to the signal processing control unit 1.

The first reducer 32 may be a planetary gear reducer, a gear reducer with a common fixed-axis gear train, a cycloidal pin gear reducer, or a worm gear reducer. Since the driving current of the first driving motor 31 is large, the first driving motor 31 is connected with the controller 2 through a power cable; in order to reduce electromagnetic interference, the first torque sensor 33 is connected to the signal processing control unit 1 via a shielded signal line.

The present embodiment gives a technical solution of the signal processing control unit 1. Mainly comprises a central processing unit, a memory and an analog-to-digital converter. The memory includes a program memory and a data memory. The analog-to-digital converter is used for converting an input analog signal into a digital signal. If the analog-to-digital converter is already integrated within the central processor, a separate analog-to-digital converter may not be necessary. In practical use, the signal processing control unit 1 may be designed separately for the purpose of miniaturizing the apparatus and reducing the cost. Of course, for convenience, off-the-shelf personal computers, industrial personal computers, and the like may also be employed.
As an alternative embodiment the system further comprises a display electrically connected to the signal processing control unit 1 for displaying data, such as data of rotation angle and moment.
As an alternative embodiment, the system further comprises a bar code reader 5 electrically connected to the signal processing control unit 1 for obtaining an identification code of the car (car to which the parking brake is to be tuned).
