Description

Technical Field

[0001] The present application relates to the technical field of lamp control, and in particular to a lamp motion device control system and a control method. Background Art

[0002] Lamps are increasingly used in urban landscapes, cultural tourism projects, and scenic spots and historical sites, adding gorgeous and dazzling scene effects to urban landmarks and scenic spots and historical sites. Such outdoor buildings often require long-distance projection. If the lamp has a little position deviation, the position will be greatly misaligned after being magnified over a long distance. Therefore, the positioning accuracy of lamps is required to be higher and higher. For example, it is necessary to hit the plaque of a landmark or a certain part of a scenic spot and historical site, and there must be no deviation. However, in the design of lamps in the prior art, the motor components are not locked when the power is off, which means that at the moment of power off, the lamp may be displaced due to gravity or inertia, or even damaged by collision of mechanical components during transportation. In addition, after the lamp is powered on, the parts with motors need to be initialized, and the initial position is found through electronic components. After the initialization is completed, the initial position is used as the base point for operation. If the usage scenario is a fixed position, the position initialization after each power-on is not only cumbersome, but also may affect the use effect due to errors. The above problems need to be solved. Summary of the invention

[0003] The main purpose of the present application is to overcome the shortcomings and deficiencies of the prior art and to provide a control system and a control method for a lamp motion device. By integrating an external input signal receiving module, a main control MCU, a motion component, a brake and a storage module, the locking and unlocking functions of the motion component are realized. Even in a power-off state, the lamp can be prevented from being displaced due to gravity or inertia, and can be prevented from being damaged due to collision of mechanical parts during transportation or installation. In addition, the position information of the motor is saved through the storage module, and there is no need for cumbersome position initialization operations.

[0038] In order to enable those skilled in the art to better understand the present application, 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. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0039] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0040] Example:

[0041] See also Figure 1 In one embodiment of the present application, a lighting fixture motion device control system is provided, comprising:

[0042] An external input signal receiving module, used for receiving an external control signal;

[0043] The main control MCU is used to process the received external control signals and generate control instructions;

[0044] A motion component, used to control the motion component to move to a specified position according to the control instruction of the main control MCU;

[0045] Brakes are used to lock and unlock moving components.

[0046] As one implementation, the external control signal received by the external input signal receiving module includes a DMX signal of a lamp. Specifically, the DMX signal in the embodiment of the present application is a digital communication protocol for controlling a lighting device, which can control the position, brightness, color, etc. of the lighting device.

[0047] The external control signal is used to indicate the target position information of the movement of the moving component.

[0048] As one of the implementation methods, the motion component includes a motor, a transmission mechanism and a Hall sensor;

[0049] The motor is used to provide power; wherein the motor also includes a motor shaft; when the motor is powered on, the motor shaft starts to rotate, thereby generating power.

[0050] The transmission mechanism is used to transmit the power provided by the motor to the motion component; wherein the transmission mechanism may include various forms such as gear transmission, belt transmission, chain transmission, etc.

[0051] The Hall sensor is used to detect the position of the motor.

[0052] In addition, the moving assembly also includes a magnet.

[0053] Specifically, the Hall sensor is a non-contact position detection element that is used in conjunction with a magnet to provide a stable magnetic field environment for the Hall sensor. When the magnetic field acts on the Hall element, a potential difference (Hall voltage) is generated on both sides of the Hall element. By detecting the change in this voltage, the position or rotation speed of the motor shaft can be accurately determined.

[0054] As one of the implementation methods, the brake of the present application controls the locking and unlocking of the moving component by controlling the on and off of a preset voltage. Among them, the brake mainly adopts a brake, which is a device that can use friction or electromagnetic force to prevent or limit the movement of an object; when necessary, it can quickly and reliably lock the moving component to prevent it from continuing to move due to inertia or other external factors. At the same time, it can quickly release the constraints on the moving component when unlocking so that the moving component can move freely.

[0055] Furthermore, the preset voltage may be 24V.

[0056] Furthermore, when the preset voltage (such as 24V) is disconnected, the electromagnet inside the brake loses its magnetism, and the brake pad or brake disc will rely on the elastic force of the spring or other elastic element to tightly hold the motor shaft, thereby applying braking force to the motor shaft in the motor to achieve locking of the moving component;

[0057] When the preset voltage (such as 24V) is turned on, the electromagnet inside the brake generates magnetism, attracting the brake pad or brake disc to separate from the motor shaft, and no braking force is applied to the motor shaft in the motor. At this time, the moving component can move freely through the rotation of the motor shaft, thereby unlocking the moving component.

[0058] In the embodiment of the present application, the brake is used to lock and unlock the moving component by controlling the on and off of the preset voltage. When the power is off, the brake automatically applies braking force to the motor shaft to lock the moving component, effectively preventing the position of the lamp from shifting due to gravity or inertia. At the same time, it also avoids damage caused by collision of mechanical parts during transportation, improves the reliability and service life of the lamp, and reduces maintenance costs.

[0059] As one implementation, the lamp motion device control system further includes a storage module for storing the position information of the motor, wherein the storage chip in the storage module may be a 20C64 model.

[0060] See also Figure 2 In another embodiment of the present application, a method for controlling a lamp motion device is provided, comprising the following steps:

[0061] After the lamp is powered on, the main control MCU determines whether there is an external control signal;

[0062] If there is an external control signal, the first position information of the motor stored in the storage module is read, the first position information of the motor is compared with the target position information indicated by the external control signal, and it is determined whether there is a change between the first position information of the motor and the target position information;

[0063] If the target position information and the first position information of the motor do not change, the preset voltage is disconnected, the brake applies a braking force to the motor shaft in the motor (holds the motor shaft tightly), locks the moving component, and the motor maintains the first position information of the motor;

[0064] If the target position information and the first position information of the motor change, the preset voltage is turned on, the brake does not apply a braking force to the motor shaft in the motor, and the motion component is unlocked;

[0065] After the unlocking motion component, the motor starts to initialize, and the motor obtains the second position information of the motor through the Hall sensor;

[0066] After the initialization is completed, based on the second position information of the motor, the motor rotates according to the external control signal until the motion component reaches the target position information;

[0067] After the moving component reaches the target position information, the storage module saves the position of the motor at this time, disconnects the preset voltage, and the brake applies a braking force to the motor shaft in the motor to lock the moving component. If an external control signal is received at this time, the last saved position of the motor is compared with the target position information indicated by the external control signal.

[0068] In addition, if there is no external control signal, the preset voltage (i.e., 24V voltage that does not enable braking) will be disconnected, the brake applies braking force to the motor shaft in the motor (keeping the motor shaft tightly held), the motor maintains the motor position before power failure, and locks the moving component.

[0069] In this embodiment, after the lamp is powered on, the main control MCU can quickly read the stored first position information of the motor and compare it with the target position information indicated by the external control signal. If the position has not changed, the motion component is directly locked; if the position has changed, the motion component is unlocked and the position is adjusted. This process greatly simplifies the position initialization step after power-on, reducing the initialization time and error.

[0070] In summary, a control system and control method for a lamp motion device of the present application can ensure that the lamp motion component can accurately run to the specified position by receiving an external control signal and generating a control instruction through processing by the main control MCU; at the same time, the setting of the brake effectively realizes the locking and unlocking functions of the motion component, and can prevent the lamp from position shifting due to gravity or inertia even in the case of power failure, and prevent the lamp from being damaged by collision of mechanical parts during transportation or installation; in addition, the position information of the motor is saved by the storage module, and is compared with the target position information indicated by the external control signal after each power-on, and the motion component is automatically locked or unlocked according to the comparison result, without the need for tedious position initialization operations.
