Description

Technical Field

[0001] This application belongs to the field of display device technology, and more specifically, relates to a display device and its control method based on the DMX512 protocol with 360° rotational reflection. Background Technology

[0002] In certain niche markets of advertising and stage lighting effects, it is necessary to display pre-shown images by splicing them together into a complete image using mechanically rotatable display devices. Currently, common such display devices typically consist of multiple rotatable display panels, which are then arrayed together. A common design involves coating different portions of an image on the front and back, or the front, of each display panel. All panels are then rotated together to a flat state, thus forming a complete image. However, this simple mechanically rotatable display device usually lacks dynamic lighting effects, and the control over the panel rotation is limited to rotating to a flat surface. It cannot precisely control the rotation angle, display dynamic patterns with lighting effects, or showcase the brilliance of light changes, resulting in relatively limited display performance. Therefore, developing a rotatable display device with intelligently controllable rotation and the addition of dynamic lighting effects, offering a better display experience, has become a problem worth solving in this industry.

[0019] This application also proposes a control method for a display device based on the DMX512 protocol with 360° rotation and reflection. This method is implemented using the aforementioned display device based on the DMX512 protocol with 360° rotation and reflection. The control method for the display device based on the DMX512 protocol with 360° rotation and reflection includes the following steps:

[0020] The display device based on the DMX512 protocol with 360° rotational reflection is powered on and completes status detection.

[0021] The PCB board receives control signals based on the DMX512 protocol. The microcontroller on the PCB board analyzes and processes the control signals to generate rotation adjustment signals and lighting adjustment signals.

[0022] The drive component receives rotation adjustment signals to control the rotation speed, rotation direction, and angle of the rotating reflector; the light source receives light adjustment signals to control the color and brightness of the emitted light.

[0023] Among them, multiple display units can be controlled in a multi-level interconnection manner, or the display units can be controlled offline.

[0024] Optionally, the steps for a display device based on the DMX512 protocol to power on and complete status detection include the following sub-steps:

[0025] The display device based on the DMX512 protocol, which rotates and reflects 360°, is powered on and enters the IAP program.

[0026] The program upgrade flag is detected. If the program upgrade flag is detected, the LED of the light source lights up in the first color, the PCB board prepares to receive the upgrade signal data, and after verifying that the data is correct and writing it, it jumps to the remote control APP; if the program upgrade flag is not detected, it jumps directly to the remote control APP.

[0027] Initialize the peripheral interface and read the memory data from the PCB board's memory;

[0028] The system determines whether the drive motor has undergone origin calibration. If the determination is yes, the display device based on the DMX512 protocol with 360° rotation and reflection is in the state of completion detection. If the determination is no, the display device based on the DMX512 protocol with 360° rotation and reflection is in the state of completion detection after the origin calibration of the drive motor is completed.

[0029] Optionally, if a program upgrade flag is detected, the LED of the light source illuminates in the first color, the PCB board prepares to receive the upgrade signal data, and after verifying that the data is correct, the process of jumping to the remote control APP includes the following sub-steps:

[0030] The control system detected a program upgrade flag;

[0031] The microcontroller on the PCB board controls the LED of the light source to light up the first color, preparing to receive data from the upgrade signal;

[0032] The microcontroller on the PCB board analyzes and judges the data of the received upgrade signal. If the data is determined to be correct, the new upgrade signal data is written. After the data is written, the LED lights up in the first color and jumps to the remote control APP. If the data is determined to be incorrect, the LED lights up in the second color. The second color is different from the first color. The software is reset and the process of powering on the display device based on the DMX512 protocol and entering the IAP program is restarted.

[0033] If the determination is negative, then after completing the drive motor origin calibration, the steps for the display device based on the DMX512 protocol to complete the 360° rotation and reflection state detection include the following sub-steps:

[0034] The microcontroller on the PCB board determined that the drive motor had not been calibrated at the origin.

[0035] The microcontroller on the PCB board controls the drive motor to start and find its initial position;

[0036] The initial position of the drive motor is detected. If the drive motor is not in the initial position, the LED flashes its first color, indicating that a hardware check is required. Then, the process of powering on the display device based on the DMX512 protocol and entering the IAP program is restarted. If the drive motor is already in the initial position, the value of the initial position is recorded and written to the memory. After writing is complete, the calibration completion flag and the interrupt flag are turned on. The display device based on the DMX512 protocol is now in the state of completion detection.

[0037] Optionally, the steps for the PCB board to receive control signals based on the DMX512 protocol include the following sub-steps:

[0038] Upon entering the main loop program, the microcontroller on the PCB board receives control signals based on the DMX512 protocol, writes the control signals into codes, and checks whether they include upgrade signals and origin signals.

[0039] If the origin signal is detected, the current position information of the drive motor is updated;

[0040] If the origin signal is not detected, the process proceeds to the step of the microcontroller on the PCB board analyzing and processing the control signal.

[0041] The steps by which the microcontroller on the PCB board analyzes and processes the control signals to generate rotation adjustment signals and lighting adjustment signals include the following sub-steps:

[0042] The microcontroller on the PCB board analyzes and processes the control signals;

[0043] If an upgrade signal is detected in the control signal, the program upgrade flag is turned on, the drive motor calibration flag is turned off, and the software is reset. The program upgrade flag detection process is then restarted.

[0044] If a write signal is detected in the control signal, the LED lights up in the third color, which is different from both the first and second colors. Address information is stored, the calibration flag of the drive motor is turned off, and the process proceeds to the steps of generating rotation adjustment signal and light adjustment signal.

[0045] If neither the upgrade signal nor the write signal is detected in the control signals, then proceed to the step of generating the rotation adjustment signal and the lighting adjustment signal;

[0046] The steps by which the drive assembly receives rotation adjustment signals to control the rotation speed, direction, and angle of the rotating reflector include the following sub-steps:

[0047] The microcontroller on the PCB board sends the corresponding rotation adjustment signal to the corresponding drive motor based on the corresponding address information;

[0048] The drive motor operates according to the rotation adjustment signal, so that the rotating reflector rotates to a predetermined angle at a predetermined rotation direction and a predetermined speed;

[0049] During the rotation of the rotating reflector, the PCB board receives data from the read head of the detection optocoupler or infrared photodiode and then determines the angle of the rotating reflector.

[0050] The steps by which a light source receives a light adjustment signal to control the color and brightness of the emitted light include the following sub-steps:

[0051] The microcontroller on the PCB board sends the corresponding lighting adjustment signal to the corresponding light source based on the corresponding address information;

[0052] The light source emits light of a predetermined color according to the light adjustment signal, and controls the brightness change of the light according to the light adjustment signal.

[0053] The beneficial effects of the 360° rotating reflective display device and control method based on the DMX512 protocol provided in this application are as follows: After the 360° rotating reflective display device based on the DMX512 protocol is powered on and completes status detection, it can receive control signals based on the DMX512 protocol. These control signals are analyzed and processed by the microcontroller on the PCB board, generating rotation adjustment signals and light adjustment signals. The rotation adjustment signal is sent to the rotation mechanism. Upon receiving this signal, the drive component controls the rotation of the rotating reflector, allowing it to rotate to a predetermined angle at a predetermined rotation direction and speed. Simultaneously, the light source located at the same reflector cup receives the light adjustment signal and emits light of a predetermined color and intensity, which illuminates the reflective surface of the rotating reflector and is then reflected to create a unique reflective light effect. Thus, by changing the rotation adjustment signal and the light adjustment signal, the rotating reflector can be automatically controlled. Combined with changes in light color and brightness, the reflective surface presents a variety of dazzling light effects, greatly improving the overall display performance and achieving a unique visual effect.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0080] This application provides a display device based on the DMX512 protocol that features 360° rotational reflection.

[0081] Please see Figures 1 to 9 In one embodiment, the display device based on the DMX512 protocol and capable of 360° rotational reflection includes one or more display units 100 assembled together. Each display unit 100 includes a housing 110, a rotation mechanism, a control system, and a light source 160. Specifically, the housing 110 is provided with a plurality of spaced-apart reflective cups 111, each reflective cup 111 having a concave inner cup surface 112, and a light outlet 113 at the bottom of the inner cup surface 112. Each reflective cup 111 is equipped with a rotation mechanism, each rotation mechanism including a drive assembly, a transmission assembly, and a reflective sheet assembly. The reflective sheet assembly includes a rotating reflective sheet 131 and a rotating shaft 132 formed by the outer edge of the rotating reflective sheet 131 extending radially outward. The transmission assembly is connected to the rotating shaft 132. The drive assembly drives the rotating reflective sheet 131 to rotate 360° within the reflective cup 111 along the axial direction of the rotating shaft 132. The front and back surfaces of the rotating reflective sheet 131 are reflective surfaces of the same or different colors. The control system includes a PCB board 150 fixed to the back of the housing 110, and a drive assembly electrically connected to the PCB board 150. A light source 160 is mounted on the PCB board 150, and each reflector cup 111 corresponds to a light source 160. Light emitted from the light source 160 exits through the light outlet 113 and reflects onto the rotating reflector 131. The microcontroller on the PCB board 150 receives control signals based on the DMX512 protocol, analyzes and processes them to generate rotation adjustment signals and lighting adjustment signals. The color and brightness changes of the light emitted from the light source 160 are controlled by the lighting adjustment signals, while the rotation speed, direction, and angle changes of the rotating reflector 131 are controlled by the rotation adjustment signals.

[0082] Based on this design, in this embodiment, after the 360° rotating and reflecting display device based on the DMX512 protocol is powered on and completes status detection, it can receive control signals based on the DMX512 protocol. These control signals are analyzed and processed by the microcontroller on the PCB board 150, generating rotation adjustment signals and light adjustment signals. The rotation adjustment signal is sent to the rotation mechanism. Upon receiving this signal, the drive component controls the rotation of the rotating reflector 131, allowing it to rotate to a predetermined angle at a predetermined direction and speed. Simultaneously, the light source 160, located at the same position as the reflector cup 111, receives the light adjustment signal and emits light of a predetermined color and intensity, which illuminates the reflective surface of the rotating reflector 131. The light is then reflected by the reflective surface to create a unique reflective light effect. Thus, by changing the rotation adjustment signal and the light adjustment signal, the rotating reflector 131 can be automatically controlled. Combined with changes in light color and brightness, the reflective surface displays a variety of dazzling light effects, significantly improving the overall display performance and achieving a unique visual effect.

[0083] It should be noted that in this application, each display unit 100 typically includes multiple reflective cups 111, which are arranged in an array to achieve a matrix-like light effect. Specifically, the rotating reflective sheet 131 in each reflective cup 111 corresponds to a rotation adjustment signal, and each light source 160 corresponds to a light adjustment signal. At any given time, the rotation adjustment signals and light adjustment signals in different reflective cups 111 may be different or the same. Therefore, multiple matrix-arranged reflective surfaces can form a preset overall light effect. At another time, the rotation adjustment signals and light adjustment signals may change, allowing the multiple reflective surfaces to form another preset overall light effect, thus achieving a change in light effect. Here, the number of display units 100 can be one or more, with multiple display units 100 spliced ​​together to achieve a matrix-like light effect, such as... Figure 8 and Figure 9 As shown, this display device based on the DMX512 protocol with 360° rotation and reflection is composed of four display units 100 spliced ​​together, forming a square shape. It can be controlled in multiple levels to create a larger display light effect. Of course, in other embodiments, the number of display units 100 included in this display device based on the DMX512 protocol with 360° rotation and reflection can be set according to actual needs, and the shape of the display units 100 is not limited to this embodiment, nor is the overall shape of the spliced ​​multiple display units 100 limited to this embodiment.

[0084] Furthermore, in this embodiment, the inner cup surface 112 of the reflective cup 111 is a concave arc surface, and the rotating reflective sheet 131 is circular. The reflective surfaces on both sides can be the same color or different colors. In other embodiments, the inner cup surface 112 can be in other forms, the rotating reflective sheet 131 can be in other shapes, and the inner cup surface 112 can also be coated with a coating to enhance reflection and scattering effects. Here, the light source 160 is preferably a high-efficiency, energy-saving LED lamp that can emit light in colors such as, but not limited to, red, green, and yellow, and the color and brightness of the light can be varied.

[0085] Please see Figures 1 to 7In this embodiment, with the front of the outer casing 110 as the front and the back as the rear, the reflector assembly also includes a bearing 133, which is sleeved on the rotating shaft 132. Here, the bearing 133 on the rotating shaft 132 effectively supports the rotating shaft 132, improving the rotational stability and accuracy of the rotating reflector 131. Specifically, the transmission assembly includes a first driven gear 141 and a second driven gear 142. The first driven gear 141 is located at the free end of the rotating shaft 132 away from the rotating reflector 131, and is coaxially arranged with the bearing 133. The second driven gear 142 is mounted on the back of the reflector cup 111, and includes a second transmission tooth portion 142a and a second driven tooth portion 142b, which are coaxially integrated and separated at both ends. The second driven tooth portion 142b meshes with the first driven gear 141. The drive assembly is mounted on the back of the reflector cup 111 and includes a drive motor 121 and a rotating main shaft 122 connected to the drive motor 121. The outer circumferential surface of the rotating main shaft 122 is provided with a first transmission tooth 122a. The axial direction of the rotating main shaft 122 is perpendicular to that of the second driven gear 142. The second transmission tooth 142a meshes with the first transmission tooth 122a. The drive motor 121 drives the rotating main shaft 122 to rotate axially. The rotating main shaft 122 drives the second transmission tooth 142a and the second driven tooth 142b to rotate axially. The second driven tooth 142b drives the first transmission tooth 122a and the rotating reflector 131 to rotate. In actual operation, after receiving the rotation adjustment signal, the drive motor 121 drives the main shaft 122 to rotate in the direction and speed specified by the rotation adjustment signal. Then, the first transmission gear 122a drives the second transmission gear 142a, which meshes with it, to rotate in the axially perpendicular direction. The second driven gear 142b, which is coaxially integrated with the second transmission gear 142a, also rotates synchronously. The rotation of the second driven gear 142b can synchronously drive the rotation of the first driven gear 141, which meshes with it, and finally drive the rotating shaft 132 connected to the first driven gear 141 to rotate synchronously. Here, the drive motor 121 is preferably a stepper motor that can be precisely controlled and has a small size. The rotation direction of the rotating reflector 131 is controlled by the rotation direction of the main shaft 122, the rotation speed is also controlled by the rotation speed of the main shaft 122, and the rotation angle of the rotating reflector 131 is controlled by the number of rotations or the angle of the main shaft 122.

[0086] Please see Figure 1 , Figure 3 , Figure 5 as well as Figure 7As shown, in this embodiment, a first mounting groove 114 is provided on the front side of the housing 110 at the upper opening edge of the reflector cup 111. The bearing 133 and the first driven gear 141 are accommodated in the first mounting groove 114. The first driven gear 141 meshes with the second driven gear 142b through the through hole at the bottom of the first mounting groove 114. Here, the design of the first mounting groove 114 allows half the volume of the bearing 133, the first driven gear 141, and the rotating shaft 132 to be accommodated there, avoiding these components protruding too much from the front side of the housing 110, thus affecting the display effect. The design of the through hole at the bottom of the first mounting groove 114 allows the first driven gear 141 to mesh smoothly with the second driven gear 142b. In addition, the reflector assembly also includes a bearing cover 134. The edge of the bearing cover 134 is provided with multiple rearwardly extending buckles, and the periphery of the first mounting groove 114 is provided with multiple buckle holes. The multiple buckles of the bearing cover 134 engage with the corresponding buckle holes one by one, thereby covering the bearing 133, the first driven gear 141 and the rotating shaft 132, and playing the roles of protection, waterproofing and dustproofing, and aesthetics of the outer shell 110 surface.

[0087] Furthermore, such as Figure 2 , Figure 3 as well as Figure 6 and Figure 7 As shown, on the back of the housing 110, a motor bracket 115 is fixed behind the first mounting groove 114. The drive motor 121, the rotating main shaft 122, and the second driven gear 142 are all fixed on the motor bracket 115. Specifically, on the back of the housing 110, two opposing rearwardly extending fixing plates 117 are provided in the peripheral area of ​​the reflector cup 111. The rear end of the fixing plate 117 is provided with a fixing groove 118. The two ends of the motor bracket 115 are fixed in the two fixing grooves 118. In this way, the motor bracket 115 and components such as the drive motor 121, the rotating main shaft 122, and the second driven gear 142 can be stably installed on the back of the housing 110. In addition, a motor mounting cover 116 is provided behind the motor bracket 115. The motor mounting cover 116 is connected to the mounting plate 117 and the motor bracket 115 to cover the rotating main shaft 122, the second driven gear 142 and part of the drive motor 121. It also serves to cover and protect, and to prevent water and dust.

[0088] Furthermore, such as Figures 2 to 7As shown, in this embodiment, multiple motherboard fixing posts 119 protrude from the blank space on the back of the housing 110 where the reflector cup 111 is not located. These motherboard fixing posts 119 are spaced apart, and the PCB board 150 is detachably fixed to the housing 110 via the motherboard fixing posts 119. Each display unit 100 can be fixed to different mounting media using screws or magnets. The mounting media can be, but is not limited to, walls, brackets, etc. Specifically, in this embodiment, the back of each display unit 100 has two identical PCB boards 150. Each PCB board 150 has multiple light sources 160 and is connected to the back of the housing 110 via the multiple motherboard fixing posts 119. Of course, in other embodiments, there may be one PCB board 150 or three or more PCB boards 150, depending on actual needs.

[0089] Please see Figure 3 , Figures 5 to 7 In this embodiment, the display unit 100 further includes a detection optical coupler 171 and an optical coupler fixing post 172. The reflector cup 111 is provided with a detection hole 173, which is located below the first mounting groove 114. The center of the detection hole 173 and the central axis of the rotating shaft 132 are located in the same vertical section. The optical coupler fixing post 172 protrudes from the back of the reflector cup 111 and is located around the detection hole 173. The detection optical coupler 171 is fixedly installed on the optical coupler fixing post 172 and corresponds to the position of the detection hole 173. The infrared detection line emitted by the detection optical coupler 171 is emitted from the detection hole 173. It is understandable that the detection optocoupler 171 and the corresponding detection hole 173 are set up to realize the zero-point detection of the rotating reflector 131 by using the principle of light refraction to receive the reflection of the infrared detection line. That is, when the rotating reflector 131 rotates to be perpendicular to the front of the housing 110, it can be sensed by the infrared detection line emitted from the detection hole 173, thereby generating feedback data to the microcontroller of the PCB board 150, and then determining that the rotating reflector 131 is at the zero-point position.

[0090] Please see Figure 1 , Figure 3 as well as Figures 5 to 7 In this embodiment, the display unit 100 further includes a concave diffuser 180. The bottom of the reflector cup 111 has a rearwardly protruding annular mounting flange 181. The inner sidewall of the mounting flange 181 has an annular diffuser fixing groove 182. The diffuser 180 is fixedly mounted in the light outlet 113 by being engaged in the diffuser fixing groove 182 at its edge. Light emitted from the light source 160 passes through the diffuser 180 and exits from the light outlet 113. Specifically, the diffuser 180 is a rearwardly concave circular disc, which can be, but is not limited to, made of optical-grade acrylic or similar materials. The diffuser 180 has the function of uniformly dispersing and diffusing the light emitted from the light source 160.

[0091] However, this design is not limited to this; in cases such as Figures 10 to 16 In another embodiment shown, the display unit 100 further includes a filter 190 and an infrared beam-through assembly 200. The filter 190 is disposed in the central region of the diffuser 180, and the infrared beam-through assembly 200 is fixed on the PCB board 150 and inserted into an infrared beam-through mounting hole 230 located directly behind the filter 190. The infrared beam-through assembly 200 includes an infrared beam-through tube 210 and an infrared beam-through control board 220. The infrared beam-through tube 210 is disposed at the end of the infrared beam-through control board 220 facing the filter 190, and the infrared detection line emitted by the infrared beam-through tube 210 passes through the filter 190 and is emitted from the light outlet 113. It can be understood that the filter 190 mainly serves to filter light, and the setting of the infrared beam-through assembly 200 is similar to the function of the detection optocoupler 171 in the aforementioned embodiment, both of which can realize zero-point detection of the rotating reflector 131 by emitting infrared detection light. Specifically, when the rotating reflector 131 rotates, the reading head of the infrared photodiode 210 generates data and feeds it back to the PCB board 150. Based on this data and other relevant data, such as the rotation direction and rotation speed, the PCB board 150 accurately determines the angle of the rotating reflector 131, thereby enabling real-time control of the rotating reflector 131 to reach the predetermined rotation angle.

[0092] This application also proposes a control method for a display device based on the DMX512 protocol with 360° rotational reflection. This control method is based on the aforementioned display device with the DMX512 protocol and includes the following steps:

[0093] S1. The display device based on the DMX512 protocol with 360° rotation and reflection is powered on and completes status detection;

[0094] S2, PCB board 150 receives control signals based on the DMX512 protocol. The microcontroller on PCB board 150 analyzes and processes the control signals to form rotation adjustment signals and lighting adjustment signals.

[0095] S3. The drive component receives rotation adjustment signals to control the rotation speed, rotation direction, and angle of the rotating reflector 131; the light source 160 receives light adjustment signals to control the color and brightness of the emitted light.

[0096] The multiple display units 100 can be controlled in a multi-level interconnected manner, or they can be controlled offline. When using multi-level interconnection, intelligent synchronous real-time control between the multiple display units 100 can be achieved, ensuring accurate completion of larger-size image splicing and light effect changes. Alternatively, one or more display units 100 can be controlled offline to complete the display task. Their control signals can be pre-downloaded and stored in the memory on the PCB board 150, and then retrieved and sent to the microcontroller for analysis and processing when needed.

[0097] As can be seen from the above control method, firstly, the display device based on the DMX512 protocol with 360° rotation and reflection needs to be powered on, and then status detection is completed to ensure that subsequent signal transmission and automatic control of the rotating reflector 131 and the light source 160 can be implemented correctly. Then, after receiving the control signal based on the DMX512 protocol, the PCB board 150 analyzes and processes the control signal into multiple signals, including rotation adjustment signals and light adjustment signals. Then, the rotation adjustment signal is used to realize real-time control of the rotating reflector 131, and the light adjustment signal is used to realize real-time control of the color and brightness changes of the light. Moreover, the rotating reflector 131 and the light source 160 in different reflector cups 111 are controlled separately, thereby realizing the transformation of gorgeous light effects and unique visual effects.

[0098] Furthermore, in this embodiment, the steps for the display device based on the DMX512 protocol to power on and complete the status detection include the following sub-steps:

[0099] The display device based on the DMX512 protocol, which rotates and reflects 360°, is powered on and enters the IAP program.

[0100] The program upgrade flag is detected. If the program upgrade flag is detected, the LED of the light source 160 lights up in the first color, the PCB board 150 prepares to receive the upgrade signal data, and after verifying that the data is correct and writing it, it jumps to the remote control APP; if the program upgrade flag is not detected, it directly jumps to the remote control APP.

[0101] Initialize the peripheral interface and read the memory data from the memory of PCB board 150;

[0102] The system determines whether the drive motor 121 has undergone origin calibration. If the determination is yes, the display device based on the DMX512 protocol with 360° rotation and reflection is in the state of completion detection. If the determination is no, the display device based on the DMX512 protocol with 360° rotation and reflection is in the state of completion detection after the origin calibration of the drive motor 121 is completed.

[0103] In other words, in this step, after the display device based on the DMX512 protocol and 360° rotating reflection is powered on, it is necessary to perform status checks such as whether an upgrade is needed and whether the drive motor 121 needs origin calibration before proceeding to the next step of control signal transmission. This ensures the correctness of subsequent programs and controls, and ultimately achieves the intended display effect.

[0104] Furthermore, in this embodiment, if a program upgrade flag is detected, the LED of the light source 160 illuminates in the first color, the PCB board 150 prepares to receive the upgrade signal data, and after determining that the data is correct and writing it, the step of jumping to the remote control APP includes the following sub-steps:

[0105] The control system detected a program upgrade flag;

[0106] The microcontroller on PCB board 150 controls the LEDs on light source 160 to light up the first color, preparing to receive upgrade signal data;

[0107] The microcontroller on PCB board 150 analyzes and judges the data of the received upgrade signal. If the data is determined to be correct, the new upgrade signal data is written. After the data is written, the LED lights up in the first color and jumps to the remote control APP. If the data is determined to be incorrect, the LED lights up in the second color. The second color is different from the first color. The software is reset and the process of powering on the display device based on the DMX512 protocol and entering the IAP program is restarted.

[0108] As can be seen from the above steps, when a program upgrade flag is detected, it is necessary to first determine whether the data is correct, then write the correct data, and finally redirect to the remote control APP for further operation. If the data is determined to be incorrect, the entire display device needs to be powered on and restarted from scratch.

[0109] Furthermore, in this embodiment, if the determination is negative, the step of determining that the display device based on the DMX512 protocol 360° rotation reflection is in a completed state detection state after the origin calibration of the drive motor 121 is completed includes the following sub-steps:

[0110] The microcontroller on PCB board 150 determines that the drive motor 121 has not been calibrated at the origin.

[0111] The microcontroller on PCB board 150 controls the drive motor 121 to start and find the initial position;

[0112] The initial position of the drive motor 121 is detected. If the drive motor 121 is not in the initial position, the LED flashes in the first color to indicate that a hardware check is required. Then, the process of powering on the display device based on the DMX512 protocol and entering the IAP program is restarted. If the drive motor 121 is already in the initial position, the value of the initial position is recorded and written to the memory. After writing is completed, the calibration completion flag and the interrupt flag are turned on. The display device based on the DMX512 protocol is now in the state of completion detection.

[0113] It is understandable that the above steps detail the process for calibrating the origin of the drive motor 121. If the drive motor 121 is not in its initial position after startup, it indicates a potential fault, requiring an alarm, hardware inspection, troubleshooting, and then restarting the process. If the drive motor 121 is in its initial position after startup, it indicates normal operation, ensuring accurate control of the rotation angle of the rotating reflector 131.

[0114] Furthermore, in this embodiment, the step of the PCB board 150 receiving control signals based on the DMX512 protocol includes the following sub-steps:

[0115] Upon entering the main loop program, the microcontroller on PCB board 150 receives control signals based on the DMX512 protocol, writes the control signals into codes, and checks whether they include upgrade signals and origin signals.

[0116] If the origin signal is detected, the position information of the current drive motor 121 is updated;

[0117] If the origin signal is not detected, the process proceeds to the step of the microcontroller on PCB board 150 analyzing and processing the control signal.

[0118] The microcontroller on PCB 150 analyzes and processes the control signals to generate rotation adjustment signals and lighting adjustment signals, including the following steps:

[0119] The microcontroller on PCB board 150 analyzes and processes the control signals;

[0120] If an upgrade signal is detected in the control signal, the program upgrade flag is turned on, the calibration flag of the drive motor 121 is turned off and the software is reset, and the program upgrade flag detection step is re-entered.

[0121] If a write signal is detected in the control signal, the LED lights up in the third color, which is different from both the first and second colors, and the address information is stored. The calibration flag of the drive motor 121 is turned off, and the process proceeds to the steps of generating the rotation adjustment signal and the light adjustment signal.

[0122] If no upgrade signal or write signal is detected in the control signals, the process proceeds to the step of generating rotation adjustment signal and lighting adjustment signal.

[0123] In other words, after the PCB board 150 receives the control signal based on the DMX512 protocol and writes the code, it needs to first check whether the upgrade signal and the origin signal are included. If the upgrade signal is detected, it means that a software reset is required before re-entering the program to check the program upgrade flag and writing the correct upgrade program data.

[0124] Furthermore, in this embodiment, the step of the driving component receiving the rotation adjustment signal to control the rotation speed, rotation direction, and angle changes of the rotating reflector 131 includes the following sub-steps:

[0125] The microcontroller on PCB board 150 sends the corresponding rotation adjustment signal to the corresponding drive motor 121 according to the corresponding address information;

[0126] The drive motor 121 operates according to the rotation adjustment signal, so that the rotating reflector 131 rotates to a predetermined angle in a predetermined rotation direction and at a predetermined speed;

[0127] During the rotation of the rotating reflector 131, the PCB board 150 receives data generated by the reading head of the detection optocoupler 171 or the infrared photodiode 210 and determines the angle of the rotating reflector 131.

[0128] In other words, for different rotating reflectors 131, the microcontroller on the PCB board 150 will send corresponding rotation adjustment signals to ensure that the rotation of the rotating reflector 131 can be accurately controlled. Specifically, when the rotating reflector 131 is rotated under control, the infrared detection line emitted by the detection optocoupler 171 or the infrared photodiode 210 will illuminate the rotating reflector 131. When the rotating reflector 131 is at different rotation angles, its reflection and refraction of the infrared detection line are different, which makes the data generated by the reading head of the detection optocoupler 171 or the infrared photodiode 210 different. After these data are transmitted to the microcontroller on the PCB board 150, after further analysis and processing, the microcontroller can determine the actual rotation angle of the rotating reflector 131, thereby realizing real-time control of the rotating reflector 131.

[0129] Furthermore, in this embodiment, the step of the light source 160 receiving the light adjustment signal to regulate the color and brightness of the emitted light includes the following sub-steps:

[0130] The microcontroller on PCB board 150 sends the corresponding light adjustment signal to the corresponding light source 160 according to the corresponding address information;

[0131] The light source 160 emits light of a predetermined color according to the light adjustment signal, and controls the brightness change of the light according to the light adjustment signal.

[0132] In other words, for different light sources 160, the microcontroller on the PCB board 150 will send corresponding light adjustment signals. The address information of the rotating reflector 131 of the same reflector cup 111 and the light source 160 is consistent at the same time to ensure that the display effect can be accurately achieved. The light source 160 emits light of a predetermined color determined by the light adjustment signal within this time and controls the brightness change determined by the light adjustment signal, thereby achieving colorful and varied light effects.

[0133] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
