Description

Technical Field

[0001] This utility model relates to the technical field of secondary relay protection safety measures tools, specifically to a cloud-controlled magnetic safety terminal based on T-shaped positioning. Background Technology

[0002] In the operation and maintenance of industries such as power, telecommunications, and data centers, the status management of cabinet doors for equipment such as switchgear, server cabinets, and terminal boxes is a crucial aspect of ensuring safe production and equipment stability. Currently, the main technical methods for preventing abnormal opening of cabinet doors have the following two limitations:

[0003] The first type is purely physical protection, such as using padlocks or mechanical combination locks. While these locks can provide some physical protection, they have significant shortcomings: 1) Inconvenient management, with cumbersome procedures for handing over and storing keys or combination locks, and keys are easily lost; 2) Lack of status awareness, making it impossible to know whether the lock has been abnormally removed or damaged, and even more impossible to proactively report opening incidents, relying entirely on manual inspections, resulting in lag and blind spots in supervision.

[0004] The second type is a simple electronic monitoring method, such as installing door magnetic sensors on the cabinet door. These sensors typically require wiring and fixed installation, making cabinet modifications inconvenient and lacking versatility. Their core drawbacks are: 1) They can only provide alarms after the fact, lacking physical protection capabilities. They only send signals after the cabinet door is opened, unable to prevent physical intervention beforehand, and cannot effectively prevent cabinet door opening caused by vibration, accidental contact, or misoperation. 2) The alarm information is limited, with a high false alarm rate. The door magnetic sensor can only report "open / closed" status, unable to distinguish between planned authorized operations and unauthorized opening, resulting in a large number of invalid alarms in the backend, interfering with the judgment of maintenance personnel.

[0005] Therefore, the market urgently needs a new type of safety device that can provide a reliable physical locking function to prevent cabinet doors from being opened accidentally, and also has intelligent sensing and wireless communication capabilities, can actively report status events, and is easy to install and highly versatile. Utility Model Content

[0006] To address the technical problems in existing technologies, such as the separation of physical locking and electronic monitoring functions, the inability to effectively prevent misoperation, the limited electronic alarm information, and the inconvenience of installation, this utility model provides a cloud-controlled magnetic safety terminal based on T-shaped positioning. It prevents cabinet doors from being opened accidentally through physical locking, possesses intelligent sensing and wireless communication capabilities, can proactively report status events, and is easy to install and highly versatile.

[0007] The technical solution adopted by this utility model is to provide a cloud-controlled magnetic safety terminal based on T-shaped positioning, including a shell with an opening at the top, a mounting magnetic block set at the top of the shell, a PCB board and a battery set at the front end of the shell, a micro switch set on the PCB board, a cover set at the front end of the shell, a socket and a switch hole set on the upper side of the top end of the cover, and a plug set in the socket.

[0008] The PCB board, battery, and micro switch are all located inside the cover. The actuating end of the micro switch faces upward and extends vertically upward from the switch hole. The lower end of the plug is vertically inserted into the plug hole. The housing has a box structure with an opening at the top, and the cover has a box structure with an opening on one side.

[0009] The mounting magnetic blocks are provided in four places, and are located at the four corners of the opening at the top of the housing. The upper surface of the mounting magnetic blocks is flush with the upper surface of the housing.

[0010] Fixing posts are provided at the four corners of the opening of the housing. The upper end of the fixing post is flush with the upper end of the housing and is provided with a mounting groove. The mounting magnet is embedded and fixed in the mounting groove.

[0011] The fixing column is square and is an integral structure with the shell.

[0012] The insert block has a T-shaped cross-section, and the insertion hole has a T-shaped hole structure.

[0013] The upper end of the insert block is provided with a card slot, an RFID tag is embedded and fixed in the card slot, and an RFID card reader is provided on the PCB board.

[0014] The lower end of the housing is provided with a fixing groove, and a magnetic block is provided in the fixing groove.

[0015] The PCB board is provided with status indicator lights, and the underside of the cover is provided with lamp holes corresponding to the status indicator lights.

[0016] The beneficial effects of this utility model are that it provides a cloud-controlled magnetic safety terminal based on T-shaped positioning. The front end face of the shell and the cover form an inner cavity for installing the PCB board and battery. Positioning is achieved by inserting a plug into the socket. When the actuating end of the micro switch is pressed against the cabinet door, the safety terminal is in normal protection mode and serves as an identifier. When the cabinet door is opened, the safety terminal is removed, and the cabinet door is pressed against the micro switch again. The actuating end of the micro switch is activated, the state changes, and a signal is sent to remind the staff that the cabinet door has been opened, effectively achieving the effects of identification and preventing accidental contact.

Detailed Implementation

[0023] like Figure 1-5 As shown, this utility model provides a cloud-controlled magnetic safety terminal based on T-shaped positioning, including a housing 1 with an open top, a mounting magnet 2 disposed on the upper end of the housing 1, a PCB board 3 and a battery 4 disposed on the front end of the housing 1, a micro switch 5 disposed on the PCB board 3, a cover 6 disposed on the front end of the housing 1, an insertion hole and a switch hole disposed on the upper side of the upper end of the cover 6, and a plug 7 disposed in the insertion hole; the PCB board 3, the battery 4 and the micro switch 5 are all located inside the cover 6, the actuating end of the micro switch 5 faces upward and extends vertically upward from the switch hole, the lower end of the plug 7 is vertically inserted into the insertion hole, the housing 1 has a box structure with an open top, and the cover 6 has a box structure with an open side.

[0024] The cabinet doors of switch cabinets, server cabinets, or terminal boxes are equipped with manual handles that can be opened by manual rotation. The opening size at the top of the housing 1 is adapted to the manual handle, and the plug block 7 is adapted to the plug hole.

[0025] The front end face of the housing 1 and the cover 6 form an inner cavity for mounting the PCB board 3 and the battery 4. The PCB board 3 and the battery 4 are fixed on the front end face of the housing 1. The micro switch 5 is mounted on the PCB board 3. The micro switch 5 corresponds to the switch hole, and its actuating end extends upward from the switch hole. The plug 7 is movably inserted into the plug hole.

[0026] In use, first fix one end of the plug 7 to the cabinet door as a positioning point for the housing 1. The fixing position is adjusted according to the position of the manual handle on the cabinet door. The fixing method is not limited, such as adhesive. Then, align the opening of the housing 1 with the manual handle and the plug hole of the cover 6 with the plug 7. The housing 1 covers the manual handle through the upper opening and is attached to the cabinet door by the installation magnet 2. At this time, the upper end face of the housing 1 is in contact with the cabinet door. At the same time, the other end of the plug 7 is inserted into the plug hole on the cover 6. After the upper end of the housing 1 is in contact with the cabinet door, the actuating end of the micro switch 5 retracts under the action of the cabinet door. At this time, the safety terminal is installed and is in normal protection state, and it also serves as an indicator. When it is necessary to open the cabinet door, the installed terminal must be removed first. After the safety terminal is removed, the cabinet door is no longer in contact with the micro switch 5. The actuating end of the micro switch 5 extends out, the state changes, and a signal is sent to remind the staff that the cabinet door has been opened.

[0027] The safety terminal in this design covers the manual handle used when opening the cabinet door, effectively serving as a marker and preventing accidental contact. Furthermore, when the safety terminal is removed, the micro switch 5 changes state, enabling timely signal transmission.

[0028] like Figure 1 As shown, there are four mounting magnetic blocks 2, which are respectively located at the four corners of the opening at the upper end of the housing 1. The upper surface of the mounting magnetic blocks 2 is flush with the upper surface of the housing 1.

[0029] The design specifies the installation position of the magnetic block 2, which makes the adsorption more stable and the installation more convenient.

[0030] like Figure 1 As shown, fixing posts 8 are provided on the four corners of the opening of the housing 1. The upper end of the fixing post 8 is flush with the upper end of the housing 1 and is provided with a mounting groove. The mounting magnetic block 2 is embedded and fixed in the mounting groove.

[0031] This design specifies the fixing method for the installation of magnetic block 2, making production and assembly more convenient.

[0032] like Figure 1 As shown, the fixing column 8 is square and is an integral structure with the shell 1.

[0033] In this design, the fixing column 8 and the shell 1 are integrally formed, which results in higher structural strength. The square fixing column 8 is easy to manufacture.

[0034] like Figure 1 and 5 As shown, the cross-section of the insertion block 7 is T-shaped, and the insertion hole is T-shaped.

[0035] In this design, both the plug 7 and the socket are T-shaped, which achieves a foolproof design and the T-shaped structure has higher strength.

[0036] like Figure 1 and 5 As shown, the upper end of the insert 7 is provided with a card slot, and an RFID tag 9 is embedded and fixed in the card slot. An RFID card reader is provided on the PCB board 3.

[0037] The insert 7 has a built-in RFID tag 9, which is embedded and fixed in the slot. The end of the RFID tag does not protrude from the slot, making it easy to install and replace. It does not interfere with the fit of the housing 1 to the cabinet door. After the insert 7 is inserted into the socket, the RFID reader can read the information of the RFID tag. The RFID reader is not shown in the figure, which can effectively avoid incorrect installation.

[0038] like Figure 2 As shown, a fixing groove is provided at the lower end of the housing 1, and a magnetic block 10 is provided in the fixing groove.

[0039] The storage magnet 10 can be used to attach the Ancuo terminal to the tool cart, making it easy to store and use, and more convenient and flexible.

[0040] like Figure 3 As shown, a status indicator light 11 is provided on the PCB board 3, and a lamp hole 12 corresponding to the status indicator light 11 is provided on the lower side of the cover 6.

[0041] The signal indicator lights are electrically connected to the PCB board and can indicate different working states of the installed terminal through different colored lights, making it convenient for staff to observe.

[0042] The safety terminal designed in this project can be used with cloud services and an app. The safety terminal, cloud services, and app communicate wirelessly. The specific usage method is as follows:

[0043] The operator safety terminal is attached to a tool cart or toolbox by a magnetic block 10 for carrying. The RFID tag contains information about the switch cabinet to be inspected.

[0044] The operator selects or starts a task on the APP and then begins to install the safety terminal. The operator first fixes the plug 7 in a suitable position on the cabinet door, then manually attaches the housing 1 to the manual handle and inserts the plug 7 into the socket. At this time, the micro switch 5 on the PCB board is activated by the cabinet door, and the RFID reader reads the information of the RFID tag.

[0045] The cloud receives information from the RFID tag and the status information of the micro switch 5, and makes the following judgments: (1) Is the reported RFID ID consistent with the target cabinet door ID required by the current work order? (2) Is the micro switch in the "pressed" state? That is, not the initial state. After the cloud makes a successful judgment, the metering installation terminal is in the "protection is effective" state, and sends this state to the APP.

[0046] If the safety terminal is removed during the protection period, the state of micro switch 5 will change and an alarm signal will be sent to the cloud. The cloud will send the "abnormal removal" event to the APP, and the APP will remind the operator through push notifications, vibration, sound and other means.

[0047] After the operation is completed, the operator uses the "End Task" function on the app. The app then sends a "Remove Protection" command to the security terminal via the cloud. Afterward, the operator can remove the installation terminal. Since the terminal is now in the "Task Completed" state, no alarms or false alarms will be generated. It can then be reused for the next cycle.
