DETAILED DESCRIPTION

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] A display module, as shown in FIG1 , is a schematic diagram of the side structure of the display module, including a support plate 1, an isolation column 3, and a light-emitting device 2. The support plate 1 includes an inner support plate 101, an isolation plate 102, and an outer support plate 103 stacked in sequence. The isolation column 3 is arranged at the bottom edge of the support plate 1, connecting the inner support plate 101, the isolation plate 102, and the outer support plate 103 in sequence. The isolation plate 102 is located between the inner support plate 101 and the outer support plate 103, and a gap is left between the inner support plate 101 and the outer support plate 103. The light-emitting device 2 is mounted on the outer support plate 103, and a plurality of light-emitting devices 2 are provided and are respectively connected to the first controller 5 and the second controller 6. In addition, in combination with FIG1 and FIG3 , it can be seen that the upper and lower ends of the inner support plate 101 are 90° bent structures, and positioning screws 4 are installed on the bent plate surfaces at both ends. The positioning screws 4 are used to connect to the external carrier.

[0046] It should be noted that the support plate 1 serves as the overall support for the entire device, and all mounting modules are mounted on the support plate 1. The entire indicator module can be installed in the indicator box using the upper and lower positioning screws 4. In addition, the two positioning screws 4 can be coaxially arranged, and the coaxial structure forms a door opening interface, which is convenient for maintenance or opening in the event of a fault.

[0047] Furthermore, a plurality of light-emitting devices 2 are provided, and an array is mounted on the outer support plate 103 , with a total of n columns and m rows, where n is greater than or equal to 5, and m is greater than or equal to 7. For example, in FIG2 , n=5, m=7, and a total of 35 light-emitting devices 2 are provided, covering the entire outer support plate 103 .

[0048] It should be noted that, in some embodiments, the arrangement and quantity of the light emitting devices 2 are not limited to the pattern shown in FIG. 2 , and can be increased according to actual needs.

[0049] Furthermore, as shown in FIG3 , which is a schematic diagram of the back structure of the display module, a first controller 5, a second controller 6, a first transformer 7, and a second transformer 8 are also installed on the surface of the inner support plate 101 away from the isolation plate 102. The first transformer 7 is connected to the first controller 5 and is used to convert the external input voltage into the operating voltage of the first controller 5. The second transformer 8 is connected to the second controller 6 and is used to convert the external input voltage into the operating voltage of the second controller 6.

[0050] It should be noted that in Figure 3, since there are two transformers, corresponding to two sets of controllers, connected to the same light-emitting device 2, a single display can receive two sets of external input power signals and, based on actual needs, select and display information for different signals, switching between them at any time, such as switching between 1 & 2, or 3 & 4. Furthermore, in some embodiments, the number of controllers and transformers is not limited to two; as the number of controllers and transformers increases, the information that can be displayed by the display will also increase accordingly.

[0051] It should be further explained that in Figure 3, both the first controller 5 and the second controller 6 are core CPU control modules, which control the flashing and lighting of the entire indicator. Furthermore, both the first controller 5 and the second controller 6 are made of SMC, which offers high strength and excellent weather resistance. Furthermore, a transformer converts the external power supply into the 24V required by the indicator.

[0052] Furthermore, in Figure 3, several metal wire ties 9 are provided on the surface of the inner support plate 101. These are distributed around the first controller 5, the second controller 6, the first transformer 7, and the second transformer 8. The U-shaped structure allows the wiring harness to pass through the U-shaped structure, ensuring a reasonable routing layout. Furthermore, the metal wire ties 9 not only bundle and route the cables, but also serve as handles for the entire device.

[0053] Furthermore, the first controller 5 and the second controller 6 are both provided with an information burning interface 11. Simply by connecting a transmission cable to the interface, the system software and firmware can be upgraded and maintained. In addition, the first controller 5 and the second controller 6 of the present invention are both provided with a terminal 10, including a positive electrode and a negative electrode, through which other devices can be electrically connected to the first controller 5 and the second controller 6.

[0054] Furthermore, as shown in Figure 4, which is a structural schematic diagram of the light-emitting device 2, the light-emitting device 2 includes a cover 201, a lens 202 and a cover 203, wherein the cover 201 is annular and is connected to the cover 203 by a number of screws; the lens 202 is conical and is installed in the cover 203, with the end with a larger area abutting against the cover 201, and the cover 203 is cylindrical and connected to the cover 201.

[0055] It should be noted that, referring to Figures 2 and 4 , each lamp in light-emitting device 2 is equipped with a separate lens 202 and protected by a separate housing 203 and cover 201. This ensures uniform illumination at each lamp position, meeting the required illumination conditions. Lens 202 is conical, with the base of the light source positioned at the correct angle. The 35 lamps work together to form distinct digital sequences.

[0056] Figure 5 shows the operating system of the indicator module. The indicator's display is controlled by an external power supply. The external 220V power supply is supplied to the internal first and second controllers 5 and 6 via the first and second transformers 7 and 8. These two controllers then control the display. Therefore, the operating methods of the indicator module include the following:

[0057] (1) When the first controller 5 is working and the second controller 6 is not working, the first controller 5 controls the corresponding light-emitting device 2 to emit light, and displays the character information to be output.

[0058] (2) When the first controller 5 is not working and the second controller 6 is working, the second controller 6 controls the corresponding light-emitting device 2 to emit light, and displays the character information to be output.

[0059] (3) When both the first controller 5 and the second controller 6 are not working, no character information is displayed.

[0060] Due to the continuous wear and tear of the light emitting device 2, it is necessary to detect it to help staff find problems in time. Therefore, a detection method is proposed for the above-mentioned indicator module, including the following steps:

[0061] When the first controller 5 or the second controller 6 controls a set number of light emitting devices 2 to work, if the number of light emitting devices 2 that emit light is less than 50% of the set number, the corresponding first controller 5 or the second controller 6 issues an alarm message.

[0062] It should be noted that the above detection method can automatically detect during the working process, and once an abnormality occurs, the controller will alarm in real time.

[0063] For example, the 35 lamp beads on the light-emitting device 2 in Figure 2 can display different numbers and letters (e.g., 1, 2, 3, ..., A, B, C, ...) depending on the settings of the first controller 5 and the second controller 6. The display on the indicator light-emitting device 2 is also monitored. According to the settings, if the number of illuminated lamp beads does not meet the set value (for example, if the set value of the first controller 5 and the second controller 6 is 50%, and the number of illuminated lamp beads is less than 50%, the first controller 5 and the second controller 6 will automatically alarm and provide feedback), thus implementing a safety control function and automatically adjusting the alarm threshold according to usage needs. Because the first controller 5 and the second controller 6 are located directly on the indicator, the external input power is transferred directly to the internal control module after being converted by a transformer. The internal control module then controls the light-emitting device 2. During this process, the 220V AC power has strong anti-interference capabilities. Since the 24V power supply is located directly on the indicator, it is not affected by external interference, thus improving the anti-interference capabilities of the entire system.

[0064] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
