1. A method of measuring a length of a belt, including a control system, the method comprising the steps of:

  • s01;

    starting and starting the equipment, and adjusting a reference preset threshold parameter of the output current of the motor and a reference preset threshold parameter of the torque of the sliding table according to the specification of the belt to be measured;

    s02;

    sleeving a belt to be measured on the fixed pile and the sliding table, and simulating a sleeving mode in an actual working state;

    s03;

    inputting a measurement instruction through a touch screen;

    s04;

    the controller controls the motor to move the sliding table, in particular to control the sliding table and the fixed column to move reversely, so that the fixed sliding table pulls the belt;

    s05;

    detect motor output current and detect slip table moment, wherein should detect and go on in step, then carry out threshold benchmark and judge, include;

    judging whether the current of the motor is greater than a preset threshold value, if so, entering the next step, and otherwise, continuously controlling the sliding table to move;

    judging whether the moment of the sliding table is greater than a preset threshold value, if so, entering the next step, and otherwise, controlling the sliding table to move continuously;

    s06;

    turning off the motor;

    s07;

    reading sensor data and displaying the sensor data on a display screen, wherein the data is the length of the belt when the motor stops, namely the length of the belt in a working state;

    s08;

    the operation is finished;

    control system includes touch display screen, controller, spud pile, slip table, motor and installs the sensor on the slip table, overlaps the belt that awaits measuring on spud pile and slip table, through touch display screen input measurement instruction, and controller control motor drives the slip table and removes, still includes;

    the motor output current detection module is used for detecting the output current of the motor, the output end of the motor output current detection module is connected with the comparison module, a reference threshold value of the motor current is arranged in the comparison module, and the output end of the comparison module is connected with the controller;

    the sliding table torque detection module is used for detecting the sliding table torque, the output end of the sliding table torque detection module is connected with another comparison module, a reference threshold value of the sliding table torque is arranged in the comparison module, and the output end of the comparison module is connected with the controller;

    the controller controls the motor to rotate positively and negatively according to the output result of the comparison module, stops the motor and records the length between the lower sliding table and the fixed column through the sensor if the output result is greater than the reference threshold value, and continues to rotate until the detection result is greater than the threshold value if the output result is less than the reference threshold value;

    when any detection result of the motor output current or the sliding table torque is larger than the reference threshold value, the motor is turned off;

    the reference threshold value of the moment of the sliding table refers to the tension of a critical point when the belt works normally.
