Description

Technical Field

[0001] This utility model relates to the field of ring network monitoring technology, specifically a ring network interruption monitoring device. Background Technology

[0002] In fields such as industrial automation, smart grids, and data centers, ring networks are widely used due to their high reliability. The advantage of ring networks lies in their ability to self-heal within a very short time (e.g., milliseconds) using redundant paths when a link fails, ensuring uninterrupted service. However, the physical point of failure still exists and must be identified and repaired as quickly as possible to restore network redundancy and prevent a complete network outage in the event of another failure.

[0003] Currently, most ring network status monitoring devices or similar network equipment (such as industrial switches and network modules) on the market use LED indicator lights to indicate port connection status. This is the most mainstream and widely used technology. One or more light-emitting diodes (LEDs) of different colors are placed next to each network interface (such as RJ45 or M12 interfaces). The current port status is typically indicated by the LED color (e.g., green for normal connection, yellow / red for interruption or fault) and flashing frequency (e.g., solid light for a connected link, flashing for data traffic).

[0004] However, in practical industrial applications, this LED-based indicator solution has many drawbacks:

[0005] 1. Poor visibility: Industrial environments are complex, with equipment cabinets typically installed densely, and in locations that may be high or far away. Small LED lights have limited brightness, making them difficult to see clearly in strong ambient light or at a distance. Maintenance personnel must approach each piece of equipment and inspect each port individually to determine its status, resulting in extremely low efficiency.

[0006] 2. Unable to provide "non-power" status indication: LED indicators rely entirely on the device's power supply and internal chip drivers. Once the monitoring device itself stops working due to a power outage, system crash, or other malfunction, all LED indicators will turn off. At this time, maintenance personnel cannot distinguish between device failure and network failure based on appearance, rendering the diagnostic tool useless.

[0007] 3. Lack of persistent state retention: When maintenance personnel detect an alarm, if the network is briefly restored and then interrupted again, the LED status will change accordingly, failing to provide physical evidence that "the fault once occurred", which is not conducive to tracing intermittent faults. Utility Model Content

[0008] This utility model provides a ring network interruption monitoring device, which aims to solve the problems mentioned in the background art, such as the difficulty in quickly and intuitively locating fault points in noisy, multi-device or long-distance industrial sites because the port status of current equipment is usually indicated only by small LED lights.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a ring network interruption monitoring device, which includes a housing, and a plurality of network ports arranged in parallel on the housing panel and used for series connection to the ring network are provided on the upper front side of the housing.

[0010] The front side of the housing is provided with multiple status indicator units, and each network port corresponds to one of the status indicator units;

[0011] The status indication unit includes: a miniature electromagnetic drive mechanism, fixedly installed inside the housing and electrically connected to the control unit; a rotating shaft, rotatably mounted on the housing with a dual-color physical indicator plate, fixedly installed at one end of the rotating shaft, having a first indicator surface and a second indicator surface of different colors; and an elastic reset element for providing torque to the rotating shaft in a first rotational direction.

[0012] Preferably, the miniature electromagnetic drive mechanism includes an electromagnet and an armature that can be attracted to the electromagnet, and the armature is fixedly connected to the rotating shaft.

[0013] Preferably, the elastic reset element is a torsion spring sleeved on the rotating shaft, with one end fixed to the housing and the other end acting on the rotating shaft.

[0014] Preferably, when the micro electromagnetic drive mechanism is powered on, it generates a driving force, and the dual-color physical indicator is driven to a retracted state parallel to the outer surface of the housing; when the micro electromagnetic drive mechanism is de-powered, the dual-color physical indicator is driven to an upright state forming a 90-degree angle with the outer surface of the housing.

[0015] Preferably, the housing is provided with a first mechanical limiting part and a second mechanical limiting part to limit the rotation angle of the rotating shaft, which are used to precisely define the two positions of the two-color physical indicator.

[0016] Preferably, the first indicator surface is green, indicating that the network is normal; the second indicator surface is red, indicating that the network is faulty.

[0017] This ring network outage monitoring device has a simple structure and is easy to use, and has the following advantages:

[0018] 1. This utility model can quickly locate faults by setting a status indicator unit. There is no need to get close to check the flashing LED lights. The fault point can be located from many devices in a few seconds by a conspicuous red sign, which greatly shortens the average repair time.

[0019] 2. This utility model uses a dual-color physical indicator sign. The physical indicator does not rely on the screen display or the judgment of the light color. It is effective in any lighting environment and will not fail due to program crash (it will alarm when the power is off). It has strong anti-interference ability.

[0020] 3. This utility model provides a complementary and more stable indication method for traditional LED lights by setting up a micro electromagnetic drive mechanism and adopting a purely mechanical physical indication method (flipping), thus forming a double insurance.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This embodiment provides a ring network outage monitoring device, such as... Figures 1 to 4 As shown, the ring network interruption monitoring device includes a housing 1, and a plurality of network ports 2 arranged in parallel on the front upper end of the housing 1 for series connection to the ring network are provided.

[0031] The front side of the housing 1 is provided with multiple status indicator units 3, and each network port 2 corresponds to one of the status indicator units 3;

[0032] The status indication unit 3 includes: a miniature electromagnetic drive mechanism 31, which is fixedly installed inside the housing 1 and electrically connected to the control unit, the control unit being a microprocessor inside the housing 1; a rotating shaft 32, which is rotatably mounted on the housing 1 and has a dual-color physical indicator 33 fixedly installed at one end of the rotating shaft 32, having a first indicator surface 331 and a second indicator surface 332 of different colors; and an elastic reset element 34, which provides torque to the rotating shaft 32 in a direction tending towards a first rotation direction.

[0033] In one embodiment, the miniature electromagnetic drive mechanism 31 includes an electromagnet 311 and an armature 312 that can be attracted to the electromagnet 311, wherein the armature 312 is fixedly connected to the rotating shaft 32.

[0034] In this embodiment, refer to Figure 2 and Figure 3 When the electromagnet 311 and armature 312 are attracted, the elastic potential energy of the elastic reset element 34 can be stored when no fault occurs and released when a fault occurs.

[0035] In one embodiment, the elastic reset element 34 is a torsion spring sleeved on the rotating shaft 32, with one end fixed to the housing 1 and the other end acting on the rotating shaft 32.

[0036] In this embodiment, refer to Figure 2 and Figure 3 The elastic reset element 34 is used to provide torque to the rotating shaft 32 in a direction tending towards the first rotation direction.

[0037] In one embodiment, when the micro electromagnetic drive mechanism 31 is powered, it generates a driving force, and the dual-color physical indicator 33 is driven to a retracted state that is parallel to the outer surface of the housing 1; when the micro electromagnetic drive mechanism 31 is de-powered, the dual-color physical indicator 33 is driven to an upright state that forms a 90-degree angle with the outer surface of the housing 1.

[0038] In this embodiment, refer to Figure 2 and Figure 3When powered, the micro electromagnetic drive mechanism 31 generates a driving force, driving the rotating shaft 32 to rotate to the second rotation direction against the torque of the elastic reset element 34, so that the dual-color physical indicator 33 is in the first position, at which time the first indicator surface 331 faces outward; when powered off, the elastic reset element 34 drives the rotating shaft 32 to rotate in the opposite direction back to the first rotation direction, so that the dual-color physical indicator 33 bounces up to the second position, at which time the second indicator surface 332 faces outward.

[0039] In one embodiment, the housing 1 is provided with a first mechanical limiting part 11 and a second mechanical limiting part 12 to limit the rotation angle of the rotating shaft 32, which are used to precisely define the two positions of the two-color physical indicator 33.

[0040] In this embodiment, refer to Figure 1 and Figure 3 The first mechanical limiting part 11 and the second mechanical limiting part 12 are used to precisely define the two positions of the dual-color physical indicator 33.

[0041] In one embodiment, the first indicator surface 331 is green, indicating that the network is normal; the second indicator surface 332 is red, indicating that the network is faulty.

[0042] In this embodiment, refer to Figure 1 and Figure 4 By printing different colors on both sides to indicate whether there is a network failure, it is easier for staff to observe intuitively.

[0043] Working principle: When the ring network is operating normally, current or a specific signal will pass through network port 2. This current or signal is sent to the control unit inside the device, which then energizes the miniature electromagnetic drive mechanism 31. The electromagnet 311 generates magnetic force, attracting its armature 312.

[0044] Since the armature 312 is fixedly connected to the rotating shaft 32, the engaging action drives the rotating shaft 32 to overcome the torque of the elastic reset element 34 (torsion spring) and rotate. The rotation of the rotating shaft 32 causes the two-color physical indicator 33 fixed at one end to flip, so that its first indicator surface 331 (green) faces outward and remains parallel to the outer surface of the housing 1, in a retracted state. At this time, the operator can determine that the link network is normal by seeing the green displayed on the flat panel.

[0045] When an interruption occurs at a point in the ring network, the corresponding network port 2 loses power or signal. The control unit detects this change and immediately cuts off the power to the miniature electromagnetic drive mechanism 31. The electromagnet 311 loses its magnetic force, releasing the elastic potential energy stored in the elastic reset element 34, driving the rotating shaft 32 to rotate in the opposite direction and reset. The rotating shaft 32 causes the dual-color physical indicator 33 to flip and stand upright, with its second indicator surface 332 (red) facing outwards and forming an approximately 90-degree angle with the outer surface of the housing 1. The first mechanical limit part 11 and the second mechanical limit part 12 ensure that the flipping angle is precisely positioned. At this time, a red, upright indicator is very conspicuous, clearly indicating that a fault has occurred in this network line and needs to be investigated as soon as possible.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
