[0035] In order to make the objectives, technical solutions and advantages of the embodiments of the invention clearer, the technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the drawings in the embodiments of the invention. Obviously, the described embodiments are some embodiments of the invention, rather than all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the invention.

[0036] As shown in Figure 1, which is a side structural schematic diagram of an indicator module, the indicator module includes a support plate 1, an isolation column 3 and light-emitting devices 2. The support plate 1 includes an inner support plate 101, an isolation plate 102 and an outer support plate 103 which are arranged in layers in sequence. The isolation column 3 is arranged at the bottom edge of the support plate 1, and connects 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 gaps are provided with the inner support plate and the outer support plate respectively. The light-emitting devices 2 are installed on the outer support plate 103, and a plurality of light-emitting devices 2 are provided and connected with the first controller 5 and the second controller 6 respectively. In addition, it can be seen from Figures 1 and 3 that the upper and lower ends of the inner support plate 101 are bent at 90°, and positioning screws 4 are installed on the surfaces of the bent plate at both ends, and the positioning screws 4 are used for connecting with an external carrier.

[0037] It should be noted that the support plate 1 serves as the overall support of the entire device, and all installation modules are installed on the support plate 1. The overall indicator module can be installed in the indicator box through the positioning screws 4 at the upper and lower ends. In addition, the two positioning screws 4 can be arranged coaxially, and the coaxial structure forms a door opening interface for easy opening during maintenance or in case of failure.

[0038] Further, a plurality of light-emitting devices 2 are provided, and the array is installed 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 FIG. 2, n = 5 and m = 7, and a total of 35 light-emitting devices 2 are provided, covering the entire outer support plate 103.

[0039] It should be noted that in some embodiments, the arrangement and number of the light-emitting devices 2 are not limited to the pattern in FIG. 2, and can be increased according to actual needs.

[0040] Further, as shown in FIG. 3, which is a back structural schematic diagram of the indicator 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 with the first controller 5 for converting the external input voltage into the working voltage of the first controller 5, and the second transformer 8 is connected with the second controller 6 for converting the external input voltage into the working voltage of the second controller 6.

[0041] It should be noted that in Figure 3, since there are two transformers and they correspond to two sets of controllers, which are jointly connected with the same light-emitting device 2, an indicator can receive two sets of external input power signals, and select to display information of different signals according to the actual needs, and switch the display at any time, such as switching for 1 & 2, switching for 3 & 4, etc. In addition, 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 indicator will also increase correspondingly.

[0042] It should be further noted that in Figure 3, the first controller 5 and the second controller 6 are both core CPU control modules. Through the CPU control module, the flashing and lighting control of the entire indicator is realized. In addition, both the first controller 5 and the second controller 6 are made of SMC material with high strength and good weather resistance. In addition, the transformer converts the externally supplied power into the 24 V power required by the indicator.

[0043] Further, in Figure 3, a number of metal wire binding racks 9 are also provided on the surface of the inner support plate 101, and the metal wire binding racks 9 are distributed in peripheral areas of the first controller 5, the second controller 6, the first transformer 7 and the second transformer 8, and their structure is U-shaped. During the wiring process, the wire harness can pass through the U-shaped structure so that the wiring layout is reasonable. In addition, the metal wire binding racks 9 can not only realize the function of wire binding and routing, but also serve as a lifting handle for the entire device.

[0044] Furthermore, both the first controller 5 and the second controller 6 are provided with an information burning interface 11. Only by connecting a transmission cable to the interface, the software and firmware of the system can be upgraded and maintained. In addition, both the first controller 5 and the second controller 6 of the invention are provided with terminal posts 10, including positive and negative poles. Other devices can be electrically connected with the first controller 5 and the second controller 6 through the terminal posts 10.

[0045] Further, 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 housing 203, wherein the cover 201 is ring-shaped and is connected with the housing 203 through a number of screws; The lens 202 is tapered and installed in the housing 203, wherein the end with larger area is against the cover 201. The housing 203 is cylindrical and connected with the cover 201.

[0046] It should be noted that, in conjunction with Figures 2 and 4, each lamp bead of the light-emitting device 2 is configured with a separate lens 202, and is protected by a separate housing 203 and cover 201 to ensure that the illumination of each lamp position is uniform and meets the illumination conditions. The lens 202 is tapered, and the bottom is the position of the light source. The lens 202 adjusts the point light source of the light source to a light source with an appropriate angle. 35 lamp beads cooperate with each other to form different numerical sequences.

[0047] As shown in Figure 5, which is an operation system diagram of the indicator module, the display of the indicator is controlled by an external power supply. The external input 220V power is supplied to the internal first controller 5 and the internal second controller 6 via the internal first transformer 7 and the internal second transformer 8, and finally, the two controllers control the display of the indicator. Therefore, the working method of the indicator module includes the following situations: (1) When the first controller 5 is working and the second controller 6 is not working, the first controller 5 controls its corresponding light-emitting devices 2 to emit light and display the character information that needs to be output. (2) When the first controller 5 is not working and the second controller 6 is working, the second controller 6 controls its corresponding light-emitting devices 2 to emit light and display the character information that needs to be output. (3) When neither the first controller 5 nor the second controller 6 is working, no character information is displayed.

[0048] Due to the continuous wear and tear of the light-emitting devices 2, it needs to be detected to help staff find problems in time. Therefore, a detection method for the above-mentioned indicator module is proposed, which includes the following steps:

[0049] When the first controller 5 or the second controller 6 controls the operation of a set number of light-emitting devices 2, 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 sends an alarm information.

[0050] It should be noted that the above detection method can be automatically detected during the working process. Once an abnormality occurs, the controller will alarm in real time.

[0051] For example, the 35 light beads on the light-emitting devices 2 in Fig. 2 may display different numbers and letters (e.g., 1, 2, 3, ..., A, B, C, ...) according to the settings of the first controller 5 and the second controller 6. The display on the light-emitting devices 2 of the indicator is detected. According to the setting, when the number of lights does not meet the set value (for example, the setting value of the first controller 5 and the second controller 6 is 50%, and when the number of light beads is less than 50%, the first controller 5 and the second controller 6 will automatically alarm and feed back the information), the function of safety control is realized, and the alarm threshold can be self-adjusted according to the needs of use. Since the first controller 5 and the second controller 6 are directly located on the indicator, the external input power supply is directly transmitted to the internal control module after being transferred through the transformer, and then the internal control module controls the light-emitting devices 2. During this process, the 220V alternating current power itself has strong anti-interference ability, while the 24V power supply is directly located on the indicator, and external interference cannot act on it, which improves the anti-interference ability of the entire system.

[0052] Although the invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the spirit and scope of the technical solution of the various embodiments of the invention.
