The control circuit board 5 is electrically connected to and controls the DC motor 3.

[0022] The control circuit board 5 includes a single-phase bridge rectifier circuit. The control circuit board 5 controls the voltage across the DC motor 3 and thus controls the speed and torque of the motor.

[0023] The above single-phase bridge rectifier circuit structure is:

[0027] Example:

[0028] Design of movable debugging platform:

[0029] 1. Add UPS power supply

[0030] Considering that the equipment connected to the debugging table is usually 220V AC power when working on site, and the debugging table needs to power the DC motor, the UPS power supply space and the backplane wiring space are reserved during the design. Figure 2 shown.

[0031] 2. Motor control system

[0032] 2.1 Speed ​​control

[0033] The 220V AC UPS needs to be converted into DC power through a rectifier to control the DC motor. At the same time, the brushless DC motor allows the torque to be adjusted by adjusting the input voltage, thereby achieving speed control; therefore, it is only necessary to control the conduction angle of the controllable thyristor to achieve the output voltage, that is, to achieve control of the motor output speed and torque.

[0034] The relationship between the single-phase full-bridge output voltage and input voltage is:

[0035] ;

[0036] U1 is the input voltage, i.e. the UPS power supply voltage, which is transformed into U2 by the isolation transmitter and then sent to the single-phase full-control bridge. α is the conduction angle. By controlling the conduction angle of the four fully controlled thyristors, the voltage at the DC motor terminal can be controlled, and then the torque can be controlled.

[0037] The signal of the torque sensor manually operated on the debugging platform can act on the thyristor of the rectifier bridge through the corresponding motor driver to change the conduction angle, complete the output voltage control, and then realize the speed control. The control process is as follows Figure 4 as shown in .

[0038] 2.2 Direction Control

[0039] The rotation direction of the DC motor is consistent with the direction of the DC voltage, so it can be realized by simply changing the direction of the input voltage on the basis of the above. The circuit diagram to be designed is as follows Figure 5 as shown in .

[0040] SB1 is the forward button, which corresponds to the forward movement of the mobile debugging platform; SB2 is the reverse button, which corresponds to the backward movement of the mobile debugging platform; SB3 is the stop button, which corresponds to the stop of the mobile debugging platform during the forward and backward movement. Ud is the input voltage after single-phase full-bridge rectification. The electric power assist function of the mobile operating platform can be realized by controlling the torque and steering.

[0041] It should be noted that the solution to the above-mentioned technical problem requires the use of software to control the four fully-controlled thyristors VT1-VT3, but the software is only a part of the technical solution of the utility model, and its means are all existing technologies. The key to solving the technical problem of the utility model is to achieve the purpose of controllable movement by improving the connection and structure of the debugging platform. This part is a new technology of shape, structure and their combination. Therefore, it cannot be judged that the content of this application does not belong to the protection object of the utility model on the grounds that software or program needs to be used.
