[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0043] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0044] See also Figure 1 The embodiment of the present application provides a lamp operation control device and method, which specifically includes a magnetic induction module, a motor operation module and a main control MCU module; the motor operation module is connected to the lamp.

[0045] The magnetic induction module is used to obtain the rotation data of the motor shaft in the motor operation module, generate a motor movement signal according to the rotation data, and send the motor movement signal to the main control MCU module.

[0046] The main control MCU module is used to receive external control signals, generate operation control instructions according to the target coordinates in the external control signal and send them to the motor operation module; receive the motor movement signal of the magnetic induction module, and obtain the actual coordinates of the motor according to the motor movement signal and the initial coordinates; compare whether the actual coordinates of the motor are consistent with the initial coordinates or the target coordinates; if they are inconsistent, send the first force control instruction to the motor operation module.

[0047] Among them, the main control MCU module calculates the actual coordinates and target coordinates of the motor when running the control command, including the direction of the motor, and the distance and speed moved in each direction (x-axis, y-axis).

[0048] Specifically, if the main control MCU module receives an external control signal before receiving the motor movement signal, the actual coordinates of the motor are compared with the target coordinates in the last external control signal, otherwise they are compared with the initial coordinates. If the comparison result is inconsistent, it means that the lamp was manually controlled after the last external control signal was received or after it was turned on. At this time, the main control MCU module adjusts the motor control force to the first preset value so that the staff can continue manual operation.

[0049] The motor operation module is used to receive a first force control instruction from the main control MCU module, and adjust the motor control force to a first preset value according to the first force control instruction; receive an operation control instruction from the main control MCU module, adjust the motor control force to a second preset value, and rotate the motor shaft according to the operation control instruction, the first preset value being less than the second preset value.

[0050] The first preset value may be 0%; the second preset value may be 100%.

[0051] The above-mentioned embodiment provides a lamp operation control device, which acquires the rotation data of the motor shaft in real time by adding a magnetic induction module, so that the main control MCU module can accurately calculate the actual coordinates of the motor, thereby judging whether the lamp has been manually operated, and reducing the motor control strength when manual operation is detected to achieve a chasing light effect, and adjusting the lamp position to the target coordinate according to the external control signal when an external control signal is received to achieve a moving head light effect, thereby realizing the free switching of two working modes of a single lamp and greatly improving the utilization efficiency.

[0052] See also Figure 2In some embodiments, the magnetic induction module includes a magnetic rod and a magnetic encoder; the magnetic rod is arranged on the motor shaft of the motor operation module; the magnetic encoder is used to sense the rotation data of the magnetic rod and generate a motor movement signal according to the rotation data.

[0053] When the motor operation module rotates, the magnetic rod on the motor shaft also rotates, and the magnetic encoder recognizes the SN polarity change of the magnetic rod. The magnetic encoder generates a level change, that is, a motor movement signal. The main control MCU module reads the level change of the magnetic encoder to identify the specific position where the motor operation module runs. The magnetic encoder achieves accurate measurement of the rotation angle and linear displacement of the motor shaft, so that the application can achieve accurate control of the operation of the lamp.

[0054] In some embodiments, the motor operation module includes an operation unit, a motor shaft and a transmission structure connected in sequence; the transmission structure is connected to the lamp. The operation unit is connected to the main control MCU module, and is used to adjust the motor control force to a first preset value according to a first force control instruction; adjust the motor control force to a second preset value and rotate the motor shaft according to the operation control instruction.

[0055] Among them, the main control MCU module controls the operation unit, the operation unit controls the motor shaft to rotate the transmission structure, and the transmission structure drives the lamp to move. The motor operation module adopts a split structure. Even if the transmission structure or data transmission process fails, it will not affect the application to reduce the motor control force according to the actual coordinates of the motor to enter the manual control mode, that is, the chasing light mode; in addition, the separate unit structures are also convenient for independent replacement, avoiding waste of resources and saving costs.

[0056] See also Figure 3 In some embodiments, a Hall detection module is also included.

[0057] The Hall detection module is used to receive the power-on command and send out the Hall signal.

[0058] Among them, the Hall detection module includes a Hall plate and a magnetic rod. The Hall plate is fixed at the initial coordinate, and the magnetic rod is fixed on the lamp. The Hall plate is extremely sensitive to changes in the magnetic field and can respond quickly and generate corresponding electrical signals. This high sensitivity enables the Hall plate to accurately measure changes in the magnetic field. When the lamp is controlled to run to the Hall plate position, the Hall plate detects the magnetic rod and sends a level change signal, namely the Hall signal. The main control MCU module wirelessly receives the Hall signal to determine that the lamp has run to the initial coordinate.

[0059] The main control MCU module is also used to receive the power-on command and send the initialization command to the magnetic induction module and the motor operation module; after receiving the Hall signal, it sends the stop command to the motor operation module.

[0060] The motor operation module is also used to receive initialization instructions and rotate the motor shaft according to preset reset parameters; receive stop instructions and stop the rotation of the motor shaft; the magnetic induction module is also used to receive initialization instructions and clear the motor movement signal.

[0061] The preset reset parameter is a preset rotation trajectory.

[0062] See also Figure 4 , in some embodiments, a timing module is also included.

[0063] The timing module is used to receive timing instructions, start timing and send the timing duration to the main control MCU module.

[0064] The main control MCU module is also used to send a timing instruction to the timing module after sending the first force control instruction; when the timing duration is equal to the preset duration, it is determined whether the actual motor coordinates at the current moment are consistent with the actual motor coordinates at the time of sending the timing instruction; if they are consistent, a second force control instruction is sent to the motor operation module. The preset duration can be 5 seconds.

[0065] The motor operation module is also used to receive a second force control instruction to increase the motor control force to a second preset value.

[0066] The above embodiment ensures that the motor control force is continuously appropriate through timing performed at a fixed period, prevents the motor or lamp from suddenly losing power and falling when no one is operating, ensures the safety of the operator, and avoids the loss of resources and assets.

[0068] Step S11, the main control MCU module receives the external control signal, generates an operation control instruction according to the target coordinates in the external control signal, and sends the operation control instruction to the motor operation module connected to the lamp.

[0069] Step S12, the motor operation module receives the operation control instruction of the main control MCU module, adjusts the motor control force to a second preset value, and rotates the motor shaft according to the operation control instruction.

[0070] Step S13, the magnetic induction module obtains the rotation data of the motor shaft in the motor operation module, generates a motor movement signal according to the rotation data, and sends the motor movement signal to the main control MCU module.

[0071] Step S14, the main control MCU module obtains the actual coordinates of the motor according to the motor movement signal and the initial coordinates, and compares whether the actual coordinates of the motor are consistent with the initial coordinates or the target coordinates; if they are inconsistent, a first force control instruction is sent to the motor operation module.

[0072] Step S15, the motor operation module receives the first force control instruction from the main control MCU module, and adjusts the motor control force to a first preset value according to the first force control instruction, where the first preset value is less than the second preset value.
