In order to illustrate the technical solutions described in the present application, specific embodiments are used for description below.

The multi-point matrix-based demonstration control method, device, electronic equipment and system provided in this application aim to control the operation of the motor in the demonstration control system through the client processing the gray value of the image, so as to achieve the rendering effect, so that the demonstration control system does not need The control program is formulated in advance to control the operation of the motor, the operation is simple, the demonstration workload is small, and the demonstration cost is low; moreover, when the motor is controlled by the gray value, the demonstration process can be flexibly controlled and the image can be changed freely.

In some embodiments of the present application, please refer to FIG. 1. FIG. 1 is a schematic flow diagram of a basic method of a demonstration control method based on a multipoint matrix provided by an embodiment of the present application. The details are as follows:

In step S101, image information to be presented is obtained, where the image information to be presented includes obtaining gray value information of pixels in the image to be presented.

In this embodiment, the image to be demonstrated is an image that needs to be presented through a demonstration control system to control multiple motors for joint demonstration. The image to be presented may be a locally stored image selected by the client, or an externally uploaded image received by the client. Moreover, the image to be demonstrated may be a picture or a video composed of multiple image frames. After obtaining the image to be demonstrated, it is based on the fact that the image is composed of multiple pixels. For example, an image with a resolution of 1000*1000 corresponds to 1000*1000 pixels, which can be regarded as a 1000*1000 image. Point matrix. For the multiple pixels in the image to be demonstrated, it is also necessary to obtain the gray value information of each pixel in the image to be demonstrated, which is specifically obtained by performing image recognition processing.

In step S102, according to the gray value information of the pixel points, the corresponding relationship between the pixel point and the motor configured in the demonstration control system is established, wherein the corresponding relationship includes the corresponding relationship between the pixel point and The ID of the motor is associated.

In this embodiment, the demonstration control system is pre-configured with multiple motors, and the multiple motors perform joint operation to present images, thereby completing the demonstration operation based on the multipoint matrix. Among them, each motor configured in the demonstration control system has a corresponding ID identification. In this embodiment, after the client obtains the gray value information of each pixel from the image to be demonstrated, for each pixel, according to the gray value information of the pixel, it is configured in the demonstration control system. Select one of the motors to control the pixel, and associate the pixel with the ID of the selected motor to establish the correspondence between the pixel and the motor configured in the demonstration control system relationship. In this embodiment, the establishment of the corresponding relationship between the pixels and the motors configured in the demonstration control system includes setting one motor to control multiple pixels with similar gray values, and when one motor controls multiple In the case of pixels with similar gray values, the average value of gray values corresponding to the multiple pixels is specifically calculated, and the motor controls these pixels according to the average value of gray values obtained by the solution. Of course, it is understandable that one motor can also be set to control one pixel.

In some embodiments of the present application, based on a preset motor-gray value correspondence table, the gray value information of the pixel may be determined from the preset motor-gray value correspondence information table. For motors with a corresponding relationship, the pixels are associated with the ID information of the motor, so as to establish the corresponding relationship between the pixels and the motors configured in the demonstration control system. Specifically, the gray value ranges controlled by the motors are set one by one for the multiple motors configured in the demonstration control system to form a motor-gray value correspondence table. After the client obtains the gray value information of each pixel from the image to be demonstrated, it searches for each pixel according to its gray value from the motor-gray value correspondence table to determine the The gray value information of the pixel has a corresponding motor, and then the pixel is associated with the ID of the motor that has a corresponding relationship, so that the pixel and the configuration in the demonstration control system can be established Correspondence between the motors.

In step S103, the operating parameter of the motor having a corresponding relationship with the pixel is obtained according to the gray value information of the pixel, and the demonstration control system controls the motor to complete the demonstration operation according to the operating parameter.

In this embodiment, the demonstration operation of displaying images by controlling multiple motors by the demonstration control system for joint operation includes installing a demonstration object at the action end of each motor, so that the demonstration object is controlled by the motor during the demonstration operation. The position change (such as the change of the hanging height) to present the image. In this embodiment, after the client establishes the correspondence between pixels and motors in a one-to-one correspondence with all pixels in the image to be demonstrated, for each motor, it can be based on the pixel points that belong to the motor. Then calculate the operating parameters of the motor according to the preset algorithm, so that the demonstration control system controls the motor to perform the demonstration operation according to the calculated operating parameters. Wherein, the operating parameter includes the number of rotations of the motor. Since the calculated number of rotations of each motor is different, the position of the demonstration object controlled by it is different during the demonstration process, thereby presenting a picture consistent with the image to be demonstrated.

In some embodiments of the present application, a fixed ratio between the number of rotations of the motor and the gray value can be preset, and the preset ratio between the number of rotations of the motor and the gray value can be selected from the image to be demonstrated. By obtaining the gray value information of the pixel points, the number of rotations of each motor when the demonstration control system performs the demonstration operation of the image to be demonstrated can be calculated. Furthermore, the demonstration control system controls the motors to perform the demonstration operation according to the number of rotations of each motor.

The multi-point matrix-based demonstration control method provided by the foregoing embodiment obtains the image information to be demonstrated, which includes obtaining the gray value information of the pixels in the image to be demonstrated; and establishes the gray value information of the pixels according to the gray value information of the pixels. The corresponding relationship between the pixel points and the motors in the pre-configured motor array; according to the gray value information of the pixel points, the operating parameters of the motors that have a corresponding relationship with the pixel points are calculated, and then the demonstration control system is based on the The operating parameters control the motor to complete the demonstration operation. Through the above method, the demonstration control system can control the motor to run according to the gray value of each pixel in the image to be demonstrated, so that only the gray value of each pixel in the image can be recognized to present the image scene, without the need to formulate control The program is simple to operate, the demonstration workload is small, and the demonstration cost is low; moreover, when the motor is controlled by the gray value, the demonstration process can be flexibly controlled and the image can be changed freely.

In some embodiments of the present application, please refer to FIG. 2. FIG. 2 is a demonstration control method based on a multipoint matrix provided by an embodiment of the present application when the corresponding relationship between pixels and a motor configured in the demonstration control system is established. Schematic diagram of a method flow. The details are as follows:

In step S201, the gray value size identification is performed on the gray value information of each pixel obtained from the image to be demonstrated;

In step S202, based on a preset distribution rule, the corresponding relationship between each pixel point and the motor configured in the demonstration control system is established according to the gray value size, wherein the preset distribution rule includes a The gray value difference between the pixels controlled by one motor does not exceed the preset difference threshold and/or the number of pixels controlled by one motor does not exceed the preset number threshold.

In this embodiment, the number of pixels controlled by each motor can be reasonably allocated according to the number of motors configured in the demonstration control system. For example, based on the image to be demonstrated with 1000*1000 pixels, when the number of motors configured in the demonstration control system is 100*100, each motor can be evenly distributed to control about 10 pixels. Specifically, after the client obtains the gray value information of each pixel from the image to be demonstrated, it can first identify the size of the gray value of the pixel in the image to be demonstrated, and then, based on the preset allocation rule Establish the corresponding relationship between the pixel points and the motor configured in the demonstration control system according to the size of the gray value, for example, configure the pixels with similar gray value to the same motor for control. The preset allocation rule includes that the gray value difference between pixels controlled by a motor does not exceed a preset difference threshold; and/or the number of pixels controlled by a motor does not exceed a preset threshold The number threshold. Wherein, the preset difference threshold can be customized by the user according to the actual situation of the image to be presented, or it can be automatically generated by the client according to the distribution of the gray value of the pixels in the image to be presented; The preset number threshold can be customized by the user according to the actual situation of the image to be demonstrated, or it can be set by the client according to the number of motors configured in the demonstration control system and the distribution of the gray value of the pixels in the image to be demonstrated Automatic generated.

For example, if the number of pixels is 1000*1000, the gray values of some pixels in the image to be demonstrated are sorted from small to large: 3, 3, 3, 4, 5, 5, 6, 6, 6, 6, 6, 9, 9, 9, 10, 11, 11, 12, 12, 18, 18, 19, 20, 25, 25, 25, 26, 26, 26, 26... Assume that the preset difference threshold is 5, and the preset number threshold is 15. Then, based on the allocation rule, the pixels corresponding to the 13 gray values of "3, 3, 3, 4, 5, 5, 6, 6, 6, 6, 6, 6, 7" can be allocated to the same one The motor is controlled; the pixels corresponding to the 8 gray values of "9, 9, 9, 10, 11, 11, 12, 12" are allocated to the same motor for control; the "18, 18, 19, 20" The pixels corresponding to the four gray values are configured to the same motor for control; and the pixels corresponding to the four gray values of "25, 25, 25, 26, 26" are configured to the same motor for control. It is understandable that when the number of pixels whose difference threshold does not exceed 5 is greater than 15, the pixels greater than 15 can be evenly distributed to two motors. If evenly distributed to two motors, there is still a single When the number of motor control pixels is greater than 15, they are equally distributed to three motors for control, and so on.

The above embodiments can realize the load balance of each motor in the demonstration control system, and avoid the overload of individual motors.

In step S303, the DMX512 data packet is transmitted to the demonstration control system, so that the demonstration control system obtains the operating parameters of the motor according to the DMX512 data packet, so as to control the motor to complete the demonstration operation.

In this embodiment, after the client has established a one-to-one correspondence between all pixels in the image to be demonstrated and established the correspondence between pixels and motors, there may be multiple pixels for the same motor ID. The gray value of the dot, at this time, the pixels in the image to be demonstrated can be grouped according to the ID of the motor, so that the pixels with the same motor ID and their gray value information form a set of data information, As a result, multiple pieces of data information are obtained, where one group of data information corresponds to the ID of a motor. Furthermore, by sending the multiple sets of data information to the data box, the data box performs data conversion processing to generate a DMX512 data packet based on the multiple data information, and then pass the generated DMX512 data packet through RS485 The bus is transmitted to the demonstration control system. The demonstration control system analyzes the DMX512 data packet, and intercepts the gray value corresponding to each motor ID from the DMX512 data packet for calculation, and then obtains the corresponding gray value of each motor Run parameters to control the motor to complete the demonstration operation.

In step S402, encoding processing is performed on the multiple items of data in binary format to generate DMX512 data packets.

The data format of the multiple pieces of data information obtained by grouping processing is hexadecimal format. In this embodiment, after the data box receives data information whose data format is hexadecimal format, it performs binary format conversion processing on the data information to obtain multiple items corresponding to the multiple items of data information. Binary data. For example, the hexadecimal format gray value is 255 data, the data obtained after the binary format conversion processing is the data in the eight-bit binary format: 11111111. After converting the multiple sets of data information into binary format data, the multiple items of binary format data are encoded, for example, the multiple items of binary format data are connected in series in the form of a data frame, and each Frame data is associated with its corresponding motor ID to generate a DMX512 data packet. Please refer to Figure 5 for details. Figure 5 shows the encoding format of the DMX512 data packet in the multipoint matrix-based demonstration control method provided by the embodiment of this application. Schematic.
