Description

Technical Field

[0001] The utility model relates to the technical field of online monitoring, in particular to an RFID pressure plate state online monitoring device based on a tilt switch. Background Art

[0002] In the online monitoring of relay protection systems, monitoring the status of pressure plates is crucial to the safe and stable operation of power grid equipment. During routine maintenance, pressure plates are typically responsible for enabling or disabling control signals and fault handling signals for the relay protection system. However, traditional pressure plate status monitoring methods rely primarily on manual inspections and periodic checks, making it difficult to accurately monitor and provide feedback on the pressure plate's real-time status. If the pressure plate's status is abnormal during a fault or emergency, the relay protection device may not respond in a timely manner, impacting system operation and even causing equipment damage or safety incidents.

[0003] While conventional RFID offers certain advantages in device identification and tracking, it also has significant shortcomings in platen status monitoring. Conventional RFID cannot continuously and in real time detect platen status changes. This is especially true in online monitoring scenarios that require high-frequency, real-time monitoring. Its low responsiveness and intelligence make it difficult to issue timely alerts and take necessary measures when abnormalities occur. This makes it difficult to effectively ensure the reliability and safety of platen status during online monitoring of relay protection. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an RFID pressure plate state online monitoring device based on a tilt switch, and adopts a disconnectable RFID online monitoring device to achieve real-time monitoring of the pressure plate state.

[0005] The technical solution adopted by the utility model is to provide an online monitoring device for the status of an RFID pressure plate based on a tilt switch, comprising two relatively arranged columns and a pressure plate arranged between the two columns, wherein a monitoring device is fixed on the pressure plate, and the monitoring device comprises a signal generator, a tilt switch connected to the signal generator, an RFID antenna module connected to the other end of the tilt switch, and an alarm module connected to the output end of the RFID antenna module, wherein the output end of the signal generator is connected to one end of the tilt switch, and the input end of the RFID antenna module is connected to the other end of the tilt switch.

[0006] The alarm module includes a collection unit, a data processing unit connected to the output end of the collection unit, and an alarm unit connected to the data processing unit. The input end of the collection unit is connected to the output end of the RFID antenna module. The RFID antenna module is a passive RFID antenna module or an active RFID antenna module.

[0007] It also includes screws respectively arranged at the upper ends of the columns, locking nuts respectively arranged on the screws, sleeves arranged at one end of the pressure plate and slots arranged at the other end of the pressure plate. The outer diameter of the screw is smaller than the outer diameter of the locking nut and the column. One end of the pressure plate is sleeved on the screw with the help of the sleeve, and the other end is clamped on the other screw with the help of the slot. The pressure plate is located between the locking nut on the screw and the column.

[0008] The screw rods are each provided with a gasket and the number of the gaskets is at least two. The gaskets are located between the locking nut and the column, and the two ends of the pressure plate are respectively located between the gaskets.

[0009] A handle is provided at the upper end of the monitoring device.

[0010] An online monitoring device for the status of an RFID pressure plate based on a tilt switch, comprising a mounting base, sockets spaced apart on the mounting base, a pressure plate arranged above the mounting base, insertion rods spaced apart at the lower end of the pressure plate and corresponding to the sockets, and wiring terminals arranged at the lower end of the mounting base and corresponding to the sockets, the pressure plate being inserted into the sockets by means of the insertion rods and pressed against the wiring terminals, a monitoring device being fixed on the pressure plate, the monitoring device comprising a signal generator, a tilt switch connected to the signal generator, an RFID antenna module connected to the other end of the tilt switch, and an alarm module connected to the output end of the RFID antenna module, the output end of the signal generator being connected to one end of the tilt switch, and the input end of the RFID antenna module being connected to the other end of the tilt switch.

[0012] It also includes placing seats arranged on both sides of the mounting seat and placing holes arranged on the placing seats, and the placing holes correspond to the two insertion rods respectively.

[0013] It also includes a rotating hole arranged at the center of the mounting seat and a rotating rod arranged at the center of the lower end of the pressing plate. The length of the rotating rod is greater than the insertion rod, and the rotating rod is inserted into the rotating hole.

[0014] The beneficial effect of this utility model is that it provides an RFID pressure plate status online monitoring device based on a tilt switch.

DETAILED DESCRIPTION

[0021] Example 1: Figure 1-3 As shown, the utility model provides an online monitoring device 3 for the status of an RFID pressure plate 2 based on a tilt switch, comprising two relatively arranged columns 1, a pressure plate 2 arranged between the two columns 1, a monitoring device 3 being fixed on the pressure plate 2, and the monitoring device 3 comprising a signal generator, a tilt switch connected to the signal generator, an RFID antenna module connected to the other end of the tilt switch, and an alarm module connected to the output end of the RFID antenna module, the output end of the signal generator being connected to one end of the tilt switch, and the input end of the RFID antenna module being connected to the other end of the tilt switch.

[0022] like Figure 1-3As shown, the alarm module includes a collection unit, a data processing unit connected to the output end of the collection unit, and an alarm unit connected to the data processing unit. The input end of the collection unit is connected to the output end of the RFID antenna module, and the RFID antenna module is a passive RFID antenna module or an active RFID antenna module.

[0023] like Figure 1-3 As shown, it also includes screws respectively arranged at the upper ends of the columns 1, locking nuts 4 respectively arranged on the screws, sleeves arranged at one end of the pressure plate 2 and slots 5 arranged at the other end of the pressure plate 2. The outer diameter of the screw is smaller than the outer diameter of the locking nut 4 and the column 1. One end of the pressure plate 2 is sleeved on the screw with the help of the sleeve, and the other end is clamped on the other screw with the help of the slot 5. The pressure plate 2 is located between the locking nut 4 on the screw and the column 1.

[0024] like Figure 1-3 As shown, each screw is provided with a gasket 6 and the number of gaskets 6 is at least two, the gasket 6 is located between the locking nut 4 and the column 1, and the two ends of the pressure plate 2 are respectively located between the gaskets 6. The gasket 6 fits better with the pressure plate 2, and the locking is more stable.

[0025] like Figure 1-3 As shown, a handle 14 is provided on the upper end of the monitoring device 3. The handle 14 can facilitate manual operation.

[0026] This design is primarily used in online monitoring systems. When used with these systems, the initial state of platen 2 (closed or open) is first recorded as the baseline state, and this state data is stored in the online monitoring system. Simultaneously, a signal generator is used to define the RFID tag signal, and an RFID antenna module is used to receive and transmit RFID tag signals, allowing the online monitoring system to identify which platen 2 has a problem. The online monitoring system can then regularly collect and update the normal operating status of platen 2, ensuring that the baseline information is accurate and valid.

[0027] The monitoring device 3 can monitor the closed or open state of the pressure plate 1 in real time. It collects the current state data of the pressure plate 2 through the tilt switch, ensuring real-time monitoring of the state changes of the pressure plate 2 during operation. Each collected state data is compared with the baseline state to detect any abnormalities.

[0028] When the monitoring device 3 detects a change in the state of the pressure plate 2, that is, a displacement of the pressure plate 2, such as from closed to open or from open to closed, the monitoring device 3 immediately identifies the change and records the specific time and status information of the state change. This change information will be marked as "abnormal" or "normal" to determine whether an alarm is required.

[0029] If the state of platen 2 changes abnormally, such as disconnection at an unexpected time or during operation, monitoring device 3 immediately triggers an alarm and sends the alarm information to the online monitoring system's control center. The alarm information includes detailed data such as the current state of platen 2, the time of change, and the device's location, allowing personnel to quickly respond and investigate.

[0030] The monitoring device 3 is mainly composed of a signal generator, an RFID antenna module, a magnetic switch and an alarm module.

[0031] RFID antenna module: The signal generator generates RFID tag signals, and the RFID antenna module is responsible for receiving and sending RFID tag signals.

[0032] Tilt switch: The monitoring device 3 is fixed on the pressure plate 2 and moves with the movement of the pressure plate 2. When the pressure plate 2 moves or rotates, the tilt angle of the pressure plate 2 changes, which can be sensed by the tilt switch. The tilt switch is integrated with the signal generator and the RFID antenna module. When the tilt switch detects that the status of the pressure plate 2 is normal, the signal generator and the RFID antenna module are connected, and the RFID antenna module continuously sends RFID signals to the online monitoring system. When the tilt switch detects that the status of the pressure plate 1 has changed, the tilt switch disconnects the signal generator and the RFID antenna module, and the RFID signal sent by the RFID antenna module to the online monitoring system is interrupted, and an alarm is triggered.

[0033] Alarm Module: When the RFID antenna module signal is interrupted, the alarm module immediately triggers an alarm, notifying the operator and simultaneously recording the event in the system log. The alarm module can provide warnings through audible and visual alarms or push notifications, allowing users to detect abnormal operations immediately.

[0034] Example 1 is the application of the monitoring device 3 in the paddle-type pressure plate 2. One end of the pressure plate 2 is rotatably set on the screw, and the other end is clamped with another screw through the slot 5. The locking nut 4 can be tightened and can cooperate with the column 1 to clamp the two ends of the pressure plate 2 respectively. When it needs to be disconnected or closed, the locking nut 4 can be loosened first, and then one end of the pressure plate 2 is manually swung outward to disengage or close with the screw on the column 1. After completion, the locking nut 4 is tightened to clamp the pressure plate 2. The tilt switch in the monitoring device 3 senses the angle change when the pressure plate 2 swings, thereby realizing the status monitoring of the pressure plate 2, and judging whether the signal generator and the RFID antenna module are disconnected or connected, and whether the alarm is triggered.

[0035] Example 2: Figure 1 and Figure 4-5As shown, the utility model provides an RFID pressure plate state online monitoring device based on a tilt switch, comprising a mounting base 7, sockets 8 spaced apart on the mounting base 7, a pressure plate 2 arranged above the mounting base 7, insertion rods 9 spaced apart at the lower end of the pressure plate 2 and corresponding to the sockets 8, and wiring terminals 10 arranged at the lower end of the mounting base 7 and corresponding to the sockets 8, the pressure plate 2 is inserted into the socket 8 with the aid of the insertion rod 9 and pressed against the wiring terminals 10, a monitoring device 3 is fixed on the pressure plate 2, the monitoring device 3 comprises a signal generator, a tilt switch connected to the signal generator, an RFID antenna module connected to the other end of the tilt switch, and an alarm module connected to the output end of the RFID antenna module, the output end of the signal generator is connected to one end of the tilt switch, and the input end of the RFID antenna module is connected to the other end of the tilt switch.

[0036] like Figure 1 and Figure 4-5 As shown, the alarm module includes a collection unit, a data processing unit connected to the output end of the collection unit, and an alarm unit connected to the data processing unit. The input end of the collection unit is connected to the output end of the RFID antenna module, and the RFID antenna module is a passive RFID antenna module or an active RFID antenna module.

[0037] like Figure 1 and Figure 4-5 As shown, it also includes a placement seat 11 provided on both sides of the mounting seat 7 and a placement hole 12 provided on the placement seat 11, and the placement holes 12 respectively correspond to the two insertion rods 9. The placement seat 11 and the placement hole 12 can be temporarily placed when the pressure plate 2 is disconnected, which is more convenient to use.

[0038] like Figure 1 and Figure 4-5 As shown, the mounting base 7 also includes a rotation hole and a rotation rod 13 at the center of the lower end of the pressing plate 2. The rotation rod 13 is longer than the insertion rod 9 and is inserted into the rotation hole. The rotation rod 13 and the rotation hole cooperate to position the pressing plate 2 when it is picked up and rotated, making it more convenient to use.

[0039] Example 2 is the application of the monitoring device 3 in the pull-out pressure plate 2. When in use, when the pressure plate 2 is in a plugged-in state through the plug rod 9 and the socket 8 on the mounting seat 7, the plug rod 9 contacts the terminal 10 to complete the closure. The pressure plate 2 is manually lifted up to pull the plug rod 9 out of the socket 8, and the plug rod 9 is inserted into the placement hole 12 of the placement seat 11. The plug rod 9 has no contact with the terminal 10 to complete the disconnection. At this time, the pressure plate 2 is in a tilted state. The tilt switch in the monitoring device 3 fixed on the pressure plate 2 detects that the tilt angle of the pressure plate 2 has changed and immediately triggers an alarm.

[0040] A tilt switch is a sensing device used to detect angular deviation. It consists of a small cavity containing two wires of varying lengths and a conductor such as mercury or a ball bearing. When the tilt switch deflects to a certain angle, the conductor contacts the wire, turning the switch on or off, thereby providing a status signal. When used in online monitoring of relay protection systems, the tilt switch can be installed on the pressure plate 2 and detect changes in its state (closed or open) by monitoring the deviation angle of the pressure plate 2. Once the angle of the pressure plate 2 exceeds the preset range, the tilt switch automatically switches states, triggering the system to record and send a signal, helping staff to understand the status of the pressure plate in real time.
