Description

Technical Field

[0001] This invention relates to the field of relay technology, and in particular to a quick-switch relay module with status monitoring function and its monitoring method. Background Technology

[0002] With the booming development of the smart home and smart hotel industries, the layout of indoor space lighting is becoming increasingly refined, and the number of various functional lamps has increased significantly. This trend directly leads to a continuous increase in the current carried by a single lighting circuit, which in turn makes the problem of smart panel control failure more and more frequent. According to statistics, more than 90% of smart panel control failures are caused by damage to the built-in relays of the panel. Common failure forms include relay contact sticking, overcurrent burnout, and contact erosion. Traditional smart panels have the following drawbacks in troubleshooting: 1. It lacks an active fault monitoring and reporting mechanism, and cannot provide timely warnings in the early stages of relay abnormalities. It can only be detected by users passively discovering the problem or after the problem has worsened. The "window period" between the occurrence of the fault and its detection often harbors serious safety hazards—a damaged relay may cause a short circuit, and in extreme cases, it may cause the entire panel to catch fire, which may then spread to guest rooms or indoor spaces, causing property damage or even personal safety risks. 2. Traditional fault repair methods suffer from low efficiency, high cost, and strong dependence. Current repair methods mostly involve "total replacement + reconfiguration": maintenance personnel need to completely remove the faulty panel, replace it with a brand new device, and then re-perform network adaptation, control logic debugging, and other operations. This method is not only complex in terms of construction process, but also has serious technical dependence. Property maintenance personnel lack professional technical reserves and cannot complete the repair independently. They must wait for the equipment supplier to send professional personnel to handle the problem. This process often takes several days, during which the lighting system is in a state of failure for a long time, affecting the user experience. At the same time, the supplier's on-site service fee and the cost of purchasing a brand new panel also significantly increase the property's maintenance costs. Based on the above, this application proposes a fast-switching relay module with status monitoring function and its monitoring method. Summary of the Invention

[0003] Based on the technical problems existing in the background technology, the present invention proposes a fast-switching relay module with status monitoring function and its monitoring method.

[0004] The present invention proposes a quick-switch relay module with status monitoring function, including a monitoring platform, a PCB board, multiple relays, relay retaining strips, and multiple varistors. The monitoring platform is integrated into a smart panel. The relays are connected in series with their corresponding varistors. The multiple relays and multiple varistors are electrically connected to the top of the PCB board. The relay retaining strips are threaded to the top of the PLC board, and the bottom of the relay retaining strips is in close contact with the top of the multiple relays.

[0005] Preferably, multiple tubular copper pillars are welded and fixed to the top of the PCB board, and the relay is inserted into the corresponding tubular copper pillars through its pins.

[0006] Preferably, the top of the PCB board is provided with multiple resistance soldering points, and the varistor is soldered and fixed on two corresponding resistance soldering points.

[0007] Preferably, the top of the PCB board has a slot, one end of the relay pressure bar passes through the corresponding slot and is fixedly connected to a buckle that is in close contact with the bottom of the PCB board, and four sets of protrusions are integrally provided on the relay pressure bar, with the bottom of the protrusions in close contact with the top of the corresponding relay. A locking screw post is welded and fixed to the top of the PCB board. A locking screw is threaded inside the locking screw post. A movable hole is opened on the top right side of the relay pressure bar. The inner wall of the movable hole is in movable contact with the outer side of the locking screw. The top inner wall of the locking screw is in movable contact with the top right side of the relay pressure bar.

[0008] Preferably, the monitoring platform is used to send control messages to sub-devices, and to monitor and receive the status messages of each sub-device in real time, comparing the device status with the current control status.

[0009] Preferably, the PCB board is electrically connected to multiple capacitors and multiple surface-mount LEDs. The PCB board that carries relays, varistors, multiple capacitors and multiple surface-mount LEDs is called a circuit board. The circuit board is a printed circuit board used to realize the electrical connection between components. It mainly undertakes signal transmission, circuit control and relay closing. The relay is used to receive electrical signals and control the closing of the relay contacts to control the lamp to turn on and off.

[0010] This invention proposes a monitoring method for a fast-switching relay module with status monitoring function, comprising the following steps: S1: Current detection and status acquisition: The relay is connected in series with the corresponding varistor. When the room lights are controlled by the smart panel, the system monitors the current and on / off status of the varistor to determine the actual working status of the relay, including whether it is closed or whether there is an overcurrent. S2: Status comparison and logic judgment: The system compares the actual status of the relays collected with the control signals sent by the smart panel in real time. If the status is inconsistent, it is judged as a control error. S3: Fault Identification and Classification: The system identifies the following typical fault types, including relay loss, contact melting or sticking, and control signal and feedback mismatch; S4: Alarm Information Generation and Reporting: Once a fault is detected, the system immediately generates control error information or alarm signals and uploads the alarm information to the host computer or monitoring platform via the 485 protocol or Bluetooth Mesh protocol. S5: Platform Processing and Notification: The host computer transmits device status and alarm information to the control platform via the MQTT / IP protocol. The platform records and stores all control commands, device feedback and warning information for subsequent analysis. If a serious anomaly occurs, the platform automatically notifies relevant maintenance personnel to intervene. S6: Maintenance response and relay replacement; maintenance personnel execute the quick replacement procedure after receiving notification.

[0011] Preferably, in step S6, the specific logic steps for replacing the relay are as follows: S601: Disconnect the PCB board from the live and neutral wires. After confirming that the power is off, use a screwdriver to loosen the locking screws of the relay retainer to release the relay retainer. Gently remove the relay retainer. At this time, the relay is in an unsecured state. S602: Hold the faulty relay by hand to avoid pulling the pins, and pull it vertically upwards. Select a relay with the same model as the faulty relay, shorten the pins of the new relay to 1mm, align it with the tubular copper pillar on PCB1, and insert it vertically, ensuring that the pins are tightly fitted to the tubular copper pillar and the PCB. Then, replace the relay retainer on top of the relay, align it with the screw holes, and use a screwdriver to tighten the locking screws evenly with moderate pressure, ensuring that the relay retainer is tightly fitted to the relay without any wobble. S603: According to the original wiring record, connect the neutral wire N and the live wire L to the corresponding terminals on the PCB board, and tighten the wiring screws to ensure that the wire ends are not exposed to prevent short circuits. Close the main circuit breaker and observe whether the indicator lights on the PCB board light up normally. Operate each switch button on the PCB board in sequence. When pressing the switch, observe the on / off changes of the lights on the corresponding lines.

[0012] Compared with existing technologies, the beneficial effects of this invention are: This invention eliminates the window of opportunity for potential faults through proactive monitoring and early warning, effectively preventing the risks of short circuits and fires. Furthermore, it adopts a quick-replacement hardware design, allowing ordinary electricians to quickly replace individual relays without readjustment, reducing maintenance time from several days to minutes. It also reduces the cost of spare parts from complete units to relay components with a unit price of only a few yuan, while eliminating dependence on supplier technology. This fundamentally solves the pain points of traditional smart panels, such as delayed fault detection, strong dependence on maintenance, and high costs. Attached Figure Description
