[0025] In the diagram: 110 - Indicator unit; 120 - Anti-interference unit. Detailed Implementation

[0026] As described in the background section, current industrial and civilian signal control systems typically display equipment status using indicator devices, such as LEDs. In related technologies, these indicator devices are directly connected to the signal control system, making them highly susceptible to external electric field interference (such as electromagnetic interference), which can prevent them from accurately indicating the operating status of the controlled equipment and severely impact the judgment and operation of on-site personnel.

[0027] This utility model provides a status indication device, specifically including: an indication unit 110 for indicating status based on an indication voltage; and an anti-interference unit 120 for filtering the indication voltage input to the indication unit 110, wherein the anti-interference unit 120 is connected in parallel with the indication unit 110. Thus, by connecting the anti-interference unit 120 in parallel across the indication unit 110, the indication signal can be filtered, reducing interference and making the received indication signal more accurate. This allows the indication unit 110 to more accurately indicate the working status of the controlled object based on the target signal, thereby solving to some extent the problem in related technologies where the indication unit 110 cannot correctly indicate the working status of the controlled object.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0030] Figure 1 The circuit structure of a device operating status indicator according to some embodiments of the present invention is shown. For example... Figure 1 As shown, the device operation status indication device of some embodiments of the present invention includes an indication unit 110 that indicates the status based on an indication voltage, and an anti-interference unit 120 that filters the indication voltage input to the indication unit 110. The anti-interference unit 120 is connected in parallel with the indication unit 110.

[0031] In some embodiments, the indicator unit 110 is susceptible to interference from external electric fields, such as external electromagnetic interference, which can easily affect the indicator voltage input to the indicator unit 110. The anti-interference unit 120 connected in parallel with the indicator unit 110 can filter the indicator voltage input to the indicator unit 110, reduce external electromagnetic interference, and enable the indicator voltage to be input to the indicator unit 110 more accurately.

[0032] In some embodiments, the indicator unit 110 is a voltage-type indicator unit. The present invention does not impose specific limitations on the indication form of the indicator unit 110, that is, the indicator 110 can be a voltage-type sound and / or light indicator unit.

[0033] In some embodiments, the indicating unit 110 may be an LED light.

[0034] In some embodiments, the anti-interference unit 120 can be a filter unit for filtering electromagnetic waves, such as a capacitor with filtering and decoupling functions. In terms of the frequency of the filtered electromagnetic waves, the anti-interference unit 120 can be a filter unit for filtering high-frequency electromagnetic waves or a filter unit for filtering low-frequency electromagnetic waves; its specific function can be determined according to the interference from the external electric field.

[0035] In some embodiments, the anti-interference unit 120 includes at least one capacitor. For example, the anti-interference unit 120 can be a single capacitor connected directly in parallel with the indicator unit 110. Furthermore, the capacitance of the anti-interference unit 120 can be adjusted, and the specific capacitance can be determined according to the frequency of the external electromagnetic wave. For example, the anti-interference unit 120 can be a capacitor with a capacitance of 1µF that filters high-frequency electromagnetic waves.

[0036] In some embodiments, the anti-interference unit 120 may also be multiple capacitors, which are connected in series and / or in parallel to adjust to a reasonable capacity and then connected in parallel to the indicator unit 110.

[0037] Specifically, the anti-interference unit 120 may include multiple capacitors connected in series, or multiple capacitors connected in parallel.

[0038] In some embodiments, the anti-interference unit 120 may further include multiple groups of capacitors connected in parallel, with each group comprising multiple capacitors connected in series. Alternatively, the anti-interference unit 120 may include multiple groups of capacitors connected in series, with each group comprising multiple capacitors connected in parallel. This invention does not limit the specific connection method of the multiple capacitors.

[0039] In some embodiments, to facilitate parallel connection of the anti-interference unit 120 with the indicator unit 110, the anti-interference unit 120 can be a non-polarized capacitor. Further, the anti-interference unit 120 can be a 630V 1µF non-polarized capacitor.

[0040] In some embodiments, if there are multiple indicator units, at least one anti-interference unit can be connected in parallel for filtering for each indicator unit.

[0041] Furthermore, in some embodiments, the anti-interference unit 120 can also be an intermediate relay coil capable of filtering. When the anti-interference unit 120 is an intermediate relay coil, the normally open contact of the intermediate relay coil can also be connected in series on the side of the indicator unit 110 provided in this utility model, and the intermediate relay coil is connected in parallel to the indicator unit 110 and the normally open contact.

[0042] This utility model also provides a control box, including: a control box body; and a plurality of status indicator devices, each of which is disposed on the control box body.

[0043] In some embodiments, if there are multiple status indication devices, they can be connected in series and / or in parallel according to user requirements.

[0044] Specifically, the plurality of status indicator devices can be connected in series. The plurality of status indicator devices can also be connected in parallel.

[0045] In some embodiments, the plurality of status indicator devices are grouped, and the groups of status indicator devices can be connected in parallel, while each group of status indicator devices can be connected in series. Alternatively, the groups of status indicator devices can be connected in series, while each group of status indicator devices can be connected in parallel.

[0046] This invention does not impose any restrictions on the specific connection method of multiple status indicator devices.

[0047] To better understand the status indication device provided by this utility model, an example is given below. Currently, LED indicator lights are widely used in industrial and civilian signal control systems due to their low energy consumption, high brightness, and long lifespan. Figure 2 The circuit concept of a device operating status indication device according to some embodiments of the present invention is shown. For example... Figure 2 As shown in the examples below, the indicator unit 110 can be an LED light, and the anti-interference unit 120 can be a non-polarized capacitor.

[0048] By utilizing the filtering characteristics of capacitors, non-polarized capacitors can be connected in parallel to the two terminals of the LED indicator to suppress electromagnetic interference. The specific capacitor size should be selected based on the frequency of electromagnetic interference at the site. In the example, a 630V 1UF non-polarized capacitor can be connected in parallel to completely suppress interference.

[0049] Figure 3 The circuit concept of a device operating status indication device according to other embodiments of the present invention is shown. For example... Figure 3 As shown, the indicator unit 110 can be an LED light, the anti-interference unit 120 can be an intermediate relay coil, and 130 can be a normally open contact of the anti-interference unit 120.

[0050] The device for indicating the operating status of the equipment provided by this utility model can effectively solve the problem of external electromagnetic interference interfering with the indication of LED indicator lights, and can correctly indicate the working status of the controlled object, ensuring stable operation and running.
