[0044] like Figure 1 The figure is a schematic diagram of the structure of a planer speed control system proposed by the present invention, which may include: a digital display touch unit, a central control unit and three independent speed adjustment units. The digital display touch unit and each speed adjustment unit are respectively connected to the central control unit for communication.

[0045] The speed regulating units in the embodiment of the present invention are respectively connected to the planer cutter head, and are used to control the speed of the planer cutter head in different steering modes. The three independent speed regulating units are respectively a first speed regulating unit, a second speed regulating unit and a third speed regulating unit. Among them, the first speed regulating unit is used to adjust the forward speed of the planer cutter head; the second speed regulating unit is used to adjust the reverse speed of the planer cutter head; and the third speed regulating unit is used to adjust the reciprocating speed of the planer cutter head.

[0046] like Figure 2As shown, it is a structural schematic diagram of the digital display touch unit proposed in an embodiment of the present invention, which can be used to display and / or select planing parameters; planing parameters include the type of cutter head (e.g., H1), steering mode (e.g., forward, reverse, reciprocating) and speed information (e.g., 12500 / RPM), etc. The embodiment of the present invention is provided with a digital display touch device that can intuitively display the cutter head, steering, speed and corresponding adjustments, and the doctor can easily select it through the touch screen. For example, the speed of different steering directions can be set separately according to the needs, so as to avoid the speed setting of one steering direction changing and the speed setting of other steering directions also changing accordingly. The central control unit in the embodiment of the present invention can be a single-chip microcomputer that performs data analysis and processing and command reception / issuance, and is used to control the speed adjustment unit corresponding to the target steering mode to adjust the cutter head speed in response to the planing parameters selected by the doctor through the digital display touch unit.

[0047] Furthermore, if Figure 3 As shown, it is a schematic diagram of the structure of the speed regulating unit proposed in an embodiment of the present invention, which may include a motor driver and a speed sensor; the motor driver and the speed sensor are respectively connected to the central control unit for communication. The central control unit can be used to obtain the Hall signal collected by the speed sensor, perform calculations on the Hall signal and the speed information to obtain the output frequency, and use the output frequency to control the motor driver to control the rotation of the cutter head based on the speed information. The working principle of the embodiment of the present invention for controlling the rotation of the cutter head is that when the speed of the cutter head needs to be adjusted, the Hall signal collected by the speed sensor is sent to the closed-loop speed motor controller to obtain a speed pulse signal, and the pulse signal is sent to the central control unit through the I / O port, and the PID algorithm is performed with the standard pulse in the central control unit, and then the output frequency is adjusted to control the speed of the motor to remain at the set value.

[0048] In an optional embodiment, a planer speed control system proposed in an embodiment of the present invention may further include a memory; the memory is connected to the central control unit for storing the rotation speed information set by the digital display touch unit; the rotation speed information includes the rotation speed value; the central control unit may also be used to call the rotation speed information stored in the memory to control the rotation of the cutter head. In other words, the rotation speed information set by the doctor may be stored in the memory in the corresponding rotation speed adjustment unit, so as to directly call the rotation speed value stored in the memory to control the rotation of the cutter head in subsequent use.

[0049] In an optional embodiment, the central control unit in the embodiment of the present invention can also be used to read the model information of the blade head after the blade head is inserted into the planer; determine whether the model information is consistent with the type of blade head selected by the doctor through the digital display touch unit; when the model information is inconsistent with the type of blade head, prompt a blade head error through the digital display touch unit to remind the doctor to replace the blade head.

[0050] A planer speed control system proposed in an embodiment of the present invention independently adjusts the rotation speed in each mode. During the operation, the doctor can cooperate with the three independent buttons of the planer head to continuously output multiple rotation directions, and finely trim the planing effect desired by the doctor, thereby enhancing the precision of the operation; the doctor has greater operational freedom during the operation, can respond to various complex situations more flexibly, and improve the success rate and safety of the operation; based on the addition of multiple safety protection mechanisms, the risk caused by equipment failure during the operation is effectively reduced, providing a safer and more reliable operating environment for doctors and patients.

[0051] Furthermore, if Figure 4 As shown, the embodiment of the present invention also provides an application Figure 1 The planer speed control method without the planer speed control system shown comprises steps S401-S402:

[0052] Step S401: adjusting planing parameters through the digital display touch unit, and sending the planing parameters to the central control unit; the planing parameters include steering mode and / or speed information.

[0053] It should be noted that, in the embodiment of the present invention, before the doctor selects the planing parameters through the digital display touch unit, the corresponding configuration information of the cutter head can be called for display first. Specifically, the type of cutter head can be selected through the digital display touch unit, and the cutter head can be inserted into the planer; the model information of the cutter head can be read; it can be determined whether the model information is consistent with the type of cutter head selected by the doctor through the digital display touch unit; if the model information is inconsistent with the type of cutter head, the digital display touch unit can be used to prompt a cutter head error to remind the doctor to replace the cutter head. After the doctor replaces the cutter head with the correct model information, the central control unit can be used to call the configuration parameters corresponding to the model information, and the configuration parameters can be displayed on the screen through the digital display touch unit for the doctor's reference and / or selection.

[0054] Step S402: the central control unit receives the planing parameters from the digital display touch unit, determines the speed adjustment unit corresponding to the steering mode, and controls the speed adjustment unit to control the rotation of the cutter head according to the speed information.

[0055] Specifically, the doctor can select the planing parameters through the digital display touch unit and send the planing parameters to the central control unit; the planing parameters include steering mode and / or speed information; the central control unit receives the planing parameters from the digital display touch unit, determines the speed adjustment unit corresponding to the steering mode, and controls the speed adjustment unit to control the rotation of the cutter head according to the speed information.

[0056] In actual operation, the doctor can first select the steering mode through the digital display touch unit, determine the corresponding target speed adjustment unit based on the steering mode, and then set the speed value for the target speed adjustment unit so that the target speed adjustment unit controls the rotation of the blade according to the speed value.

[0057] Furthermore, the memory can also receive the speed information from the central control unit and store the speed information. The central control unit can then directly call the speed information in the memory to control the rotation of the cutter head. Specifically, the speed adjustment unit is equipped with a motor driver and a speed sensor. The central control unit can process the speed information to obtain the output frequency, and use the output frequency to control the motor driver to control the rotation of the cutter head based on the speed information.

[0058] A planer speed control method proposed in an embodiment of the present invention selects planing parameters through a digital touch unit and sends the planing parameters to a central control unit; the planing parameters include steering mode and / or speed information; the central control unit receives the planing parameters from the digital touch unit, determines the speed adjustment unit corresponding to the steering mode, and controls the speed adjustment unit to control the rotation of the cutter head according to the speed information. Through the present invention, the speed in each mode can be adjusted independently. During the operation, the doctor can cooperate with the three independent buttons of the planing cutter head to continuously output multiple rotation directions, finely trim the doctor's desired planing effect, and enhance the precision of the operation; the doctor has greater operational freedom during the operation, can more flexibly deal with various complex situations, and improve the success rate and safety of the operation; based on the addition of multiple safety protection mechanisms, the risk caused by equipment failure during the operation is effectively reduced, providing a safer and more reliable operating environment for doctors and patients.
