Description

Technical Field

[0001] This invention relates to the field of equipment safety technology, specifically to an intelligent locking and tagging system and method for security doors. Background Technology

[0002] Personnel entering areas with hazardous energy sources (electrical, high-pressure gas, hydraulic, etc.) for maintenance, debugging, cleaning, or loading / unloading face the risk of bodily injury, disability, or even death. A common management practice in global enterprises is "lock-and-tagged (LOTO)" systems. Lock-and-tagged items include main power switches for electrical cabinets, equipment safety doors, safety light curtains, high-pressure gas switches, and hydraulic power switches. The specific procedure involves personnel entering the hazardous area first turning off the energy source, locking the door, and then taking the key with them. This is to prevent others from accidentally activating the energy switch and causing injury to personnel in the hazardous area.

[0003] Lockout tagging (LOTO) has long been a crucial safety standard for equipment use. Most manufacturers worldwide require maintenance personnel to adhere to this procedure to prevent accidental opening of equipment during maintenance or use, ensuring personnel safety. Current technology typically involves fencing off areas with hazardous energy sources (wire mesh) to prevent personnel from approaching and causing injury. The fence includes safety doors for personnel to enter and exit during maintenance, debugging, cleaning, or loading / unloading operations. When the safety door is opened, a switch automatically cuts off the power supply, ensuring the safety of personnel inside. However, to prevent a third party from closing the door and activating the power supply, personnel manually lock a door-blocking mechanism (plate) before entering, taking the only key with them and attaching a prominent identification tag containing their name and phone number. This lock prevents unauthorized removal of the barrier (plate) and accidental slamming of the door, ensuring no power supply. Upon exiting, personnel must unlock their own lock with their key and take it with them along with their identification tag. When multiple people enter the danger zone, each person must lock and tag their lock.

[0004] Because the existing lock-and-tag measures require manual operation, relevant personnel often forget to lock and tag, and sometimes even completely ignore the implementation of the lock-and-tag measures. Moreover, when this lock-and-tag control measure is not implemented, it cannot be supervised, and there are no records of its implementation that can be checked and traced. Summary of the Invention

[0005] The main objective of this invention is to provide an intelligent locking and tagging system and method for security doors, which solves the technical problems of existing locking and tagging measures, such as the need for manual operation, forgetting to lock and tag, neglecting to implement locking and tagging measures, lack of supervision when not implemented, and lack of traceability of implementation records.

[0006] To address the above problems, the present invention provides the following technical solution:

[0007] A smart locking and tagging system for security doors includes a lock body base, an RFID reader, and an MCU controller. The lock body base is fixed to the door frame or security door. A baffle is slidably installed inside the lock body base, with one end of the baffle connected to one end of an elastic element. The elastic element is fixed inside the lock body base. When the security door is opened, the elastic element causes the baffle to extend out of the lock body base. The baffle has a latch. When the baffle extends out of the lock body base, the latch corresponds to the position of the bolt. The bolt is connected to the drive shaft of an electromagnetic lock or electric lock. The electromagnetic lock or electric lock is electrically connected to a drive module installed inside the lock body base. When the baffle extends out of the lock body base under the action of the elastic element, the drive shaft pops out, causing the bolt to lock in the latch.

[0008] The MCU controller is electrically connected to the drive module, the display mounted on the lock body base, and the RFID reader. When the RFID reader receives tag information or tag removal information, the MCU controller processes the information and sends it to the display.

[0009] Preferably, the system further includes a network communication module, a server, a smart gateway, a voice module, and a warning light. The network communication module is electrically connected to the MCU controller, and the MCU controller is electrically connected to the voice module and the warning light. The network communication module communicates with the server through the gateway. The MCU controller monitors the locking and tagging operations according to a preset operation time limit and feeds back the working information of the tagging and locking system, including alarm information, tagging information, or tag removal information, to the display and the server. The server is used to receive and store the information.

[0010] Preferably, the network communication module is one of a 5G module, a 4G module, a Bluetooth module, or a WIFI module.

[0011] Preferably, the baffle is triggered by a position switch, and the position switch feeds back the baffle position information to the MCU controller.

[0012] A smart locking and tagging method for security doors, characterized by including the following steps:

[0013] Step 1: Pull open the safety door, and the baffle will automatically pop out under the elastic force of the elastic element;

[0014] Step 2: When the baffle is in the pop-out state, the electromagnetic lock or electric lock extends the locking tongue to lock the position of the baffle.

[0015] Step 3: The voice module issues a prompt for personnel to hang up their tags. Personnel entering the premises need to swipe their tags at the RFID reader. The system will verify the personnel's qualifications. If an unqualified person hangs up their tag, the MCU controller will send an alarm message to the smart gateway through the communication module. The smart gateway will then send the alarm message to the server. At the same time, the system continues to run the tag hanging operation. The display and the server monitor will show the prompt message "No tag hanging qualification, please confirm". The server records the lock-up and tag hanging operation until at least one person hangs up their tag, at which point the voice prompt will stop.

[0016] Step 4: The personnel who have already been identified by their name tag clock in again to complete the removal of the name tag. At this time, the personnel's information disappears from the display screen and also disappears from the monitor. The time of removal of the name tag is recorded in the historical records of the server database.

[0017] Step 5: After the tag is removed, when there are no people wearing tags on the system, the MCU controller outputs a level to the drive module, which then powers on the electromagnetic lock or electric lock. After the electromagnetic lock or electric lock is powered on, the bolt retracts. At the same time, the system's voice module plays a prompt to remind people to unlock and close the door. People who have already worn tags use one hand to press the barrier to the retracted state and the other hand to close the security door.

[0018] Preferably, in step five, if the baffle is not pushed back within a certain time T, the electromagnetic lock or electric lock is de-energized, and the bolt pops out to lock the baffle.

[0019] Preferably, in step three, when personnel are performing the tagging operation, the system will verify whether the personnel have obtained permission to perform the operation. When at least one of all tagged personnel has obtained permission to perform the operation, the electromagnetic lock or electric lock is energized, the bolt retracts, and the personnel can press the baffle to close the security door.

[0020] Preferably, in step five, the safety door is closed, at which point the baffle is pushed into a retracted state and is in a standby state.

[0021] Preferably, the electromagnetic lock or electric lock is normally open, and when the baffle is in the pop-out state, the bolt of the electromagnetic lock or electric lock is pushed out by its own elastic element.

[0022] Preferably, in step three, if no one signs a sign for more than a certain period of time T, the system will send an alarm message to the server: "Time T has passed, no sign has been displayed, please handle."

[0023] Preferably, the electromagnetic lock or electric lock of the present invention is provided with a key-controlled mechanical unlocking structure.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention can realize the automatic pop-out of the baffle, solve the problem of manual operation of the baffle, prevent personnel from forgetting or intentionally ignoring it, ensure personnel safety, and the signal for device activation is sent to the back-end server to enable managers to supervise the on-site operation.

[0026] 2. This invention can achieve automatic locking, eliminating the need for manual locking, preventing personnel from forgetting or intentionally ignoring the lock, and ensuring personnel safety. Through voice prompts and alarms, it can ensure that personnel wear tags, preventing personnel from forgetting or intentionally ignoring the lock, and ensuring personnel safety.

[0027] 3. This invention enables electronic tagging and tag removal, prompts personnel to perform operations via voice and indicator lights, and forces personnel to perform tagging operations through control unlocking.

[0028] 4. This invention allows for manual pressing of the baffle to control the closing time window and provides voice prompts, ensuring timely door closing and preventing accidental operation.

[0029] 5. This invention enables information-based management of the concession execution process when equipment needs to supply energy under special circumstances, and it is both monitorable and recordable.

[0030] 6. This invention enables remote monitoring of the locking and tagging process via network communication and retains electronic operation records.

[0031] 7. By slightly modifying the structure of the baffle, this invention can be flexibly applied to single or double sliding or revolving doors.

[0032] 8. This invention can lock the qualifications of personnel on the system backend management system. If unqualified personnel run the operating system, an alarm message will be sent.

[0033] 9. The electromagnetic lock or electric lock of this invention adopts a normally open design, which can still be triggered in the event of power failure or network failure to achieve barrier locking, automatic locking, and unlocking with a backup key when necessary.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1-7 As shown, this embodiment provides an intelligent locking and tagging system for security doors, including a lock body base 4, an RFID reader 5, an MCU controller, and a PCB board 8. The lock body base 4 is fixed to the security door. A baffle 12 is slidably provided inside the lock body base 4. One end of the baffle 12 is connected to one end of an elastic element 9, which is fixed inside the lock body base 4. When the security door is opened, the elastic element 9 causes the baffle 12 to extend out of the lock body base 4 to prevent the security door from closing. After the tag is removed, when the security door is closed, the baffle 12 is pushed by the door or door frame, remaining retracted into the lock body base 4. The elastic element can be as follows: Figure 2 The spring shown could also be a gas spring, a hydraulic spring, an elastic steel sheet, etc.

[0046] The baffle 12 is provided with a bayonet 10, which corresponds to the position of the latch 11. The latch 11 is connected to the drive shaft of the electromagnetic lock 6 or the electric lock. The electromagnetic lock 6 or the electric lock is electrically connected to the drive module provided in the lock body base 4. When the baffle 12 extends out of the lock body base 4 under the action of the elastic element 9, the drive shaft pops out and causes the latch 11 to be locked in the bayonet 10.

[0047] The MCU controller is electrically connected to the drive module, the display 2 mounted on the lock body base 4, and the RFID reader 5. When the RFID reader 5 receives tag information or tag removal information, the MCU controller processes the information and sends it to the display 2.

[0048] The system also includes a network communication module, a server, a smart gateway, a voice module, and a warning light. The network communication module has an antenna 15, which is electrically connected to the MCU controller. The MCU controller is electrically connected to the voice module and the warning light. The network communication module communicates with the server through the gateway. The MCU controller monitors the locking and tagging operations according to a preset operation time limit and feeds back the working information of the tagging and locking system, including alarm information, tagging information, or tag removal information, to the display 2 and the server. The server is used to receive and store the information.

[0049] The network communication module is one of the following: 5G module, 4G module, Bluetooth module, or WIFI module. The above components can be freely selected according to the specific scenario.

[0050] The MCU controller, network communication module, driver module, and voice module are all integrated into PCB board 8.

[0051] The MCU controller is also electrically connected to the red, yellow and green warning lights 1 and the voice module, and the voice module is electrically connected to the speaker 33.

[0052] When the MCU controller controls the red, yellow, and green warning lights 1, it can be designed as follows: when the MCU controller is in the "waiting for tagging" state, the red light flashes;

[0053] When the system is in the "listed" state, the green light flashes;

[0054] The red light flashes when the system is in the "unlocked" state;

[0055] When the system is in the "concession approval" state, the yellow light is constantly on;

[0056] When the system is in an "inactive" state, the green light remains on.

[0057] The MCU controller is also used to monitor the locking and tagging operation according to the preset operation time limit, and to provide feedback on the working information of the locking and tagging system, including alarm information and operation information.

[0058] The electromagnetic lock or electric lock of the present invention is equipped with a mechanical unlocking structure controlled by a key.

[0059] like Figure 8 , Figure 9As shown, this embodiment also provides a smart locking and tagging method for security doors, applied to the above-mentioned system, including:

[0060] Step S1: Pull open the safety door, and the baffle 12 will automatically pop out under the elastic force of the elastic element 9;

[0061] Step S2: The electromagnetic lock or electric lock is normally open. When the baffle is in the pop-out state, the bolt of the electromagnetic lock or electric lock is pushed out by its own elastic element. When the baffle 12 is in the retracted standby state, the bolt 11 is in the retracted state. After the baffle 12 pops out, the bolt 11 is pushed out by its own elastic element and locked in the slot 10, locking the position of the baffle 12.

[0062] Step S3: The voice module issues a prompt for personnel to hang up their tags. Personnel entering the premises need to swipe their tags at the RFID reader 5. The system will verify the personnel's qualifications. If an unqualified person hangs up their tag, the MCU controller will send an alarm message to the smart gateway through the communication module. The smart gateway will then send the alarm message to the server. At the same time, the system continues to run the tag hanging operation. The display and the server monitor show the prompt message "No tag hanging qualification, please confirm!". The server records the lock-up and tag hanging operation until at least one person hangs up their tag, at which point the voice prompt stops.

[0063] Step S4: The personnel who have been wearing name tags clock in again to complete the name tag removal operation. At this time, the personnel's information disappears from the display and also disappears from the monitor. The time when the personnel removed the name tag is recorded in the historical records of the server database.

[0064] Step S5: After the tag is removed, when there are no people wearing tags on the system, the MCU controller outputs a level to the drive module, which powers the electromagnetic lock 6 or electric lock. After the electromagnetic lock 6 or electric lock is powered on, the bolt 11 retracts. At the same time, the system voice module plays a prompt voice reminding people to unlock and close the door. People use one hand to press the baffle 12 to the retracted state and the other hand to close the security door.

[0065] The baffle 12 is triggered and connected to the position switch 7. The position switch 7 can be a limit switch, photoelectric switch, etc., and the position switch 7 can be set on one side of the baffle 12.

[0066] If a limit switch is used, a protrusion is provided on the baffle 12. When it extends, the protrusion can trigger a position switch and send feedback to the MCU controller to indicate that the baffle 12 is in position. When the protrusion of the baffle 12 leaves the position switch, it is considered that the baffle 12 has retracted.

[0067] In step S1, the safety door lock is normally in standby mode. At this time, the safety door is closed, the baffle 12 is pushed by the door frame and is in a retracted state, and the spring connected to it is in a contracted state. At this time, the position switch 7 will not be triggered, and the server-side monitor will show that the safety door lock has not been opened.

[0068] In step S3, if no one signs the plaque for more than 30 seconds, the system will send an alarm message to the server: "No plaque has been displayed for more than 30 seconds, please handle it!"

[0069] In step S3, when personnel are performing the tagging operation, the system will verify whether the personnel have obtained permission to perform the operation. When at least one of the personnel who have tagged has obtained permission to perform the operation, the electromagnetic lock or electric lock is energized. After being energized, the latch 11 retracts, and the personnel can press the baffle 12 to close the security door.

[0070] In step S5, if the baffle 12 is not pushed back within 10 seconds, the electromagnetic lock 6 or electric lock is de-energized, and the latch 11 pops out to lock the baffle 12.

[0071] In step S5, the safety door is closed, and the baffle 12 is pushed by the door frame into a retracted state, and the baffle 12 is in a standby state.

[0072] In step S6, after obtaining permission to perform the concession, the security door can be manually unlocked using the spare key. After removing the tag, the door must be reopened, and the process returns to step S1.

[0073] This embodiment achieves intelligent monitoring of locking and tagging by using a smart lock in conjunction with a device switch component. The device switch component enables intelligent locking and tagging of the device, the voice module can promptly and clearly remind personnel to lock and tag the smart lock, and the network communication module, server, and smart gateway can monitor and record the entire locking and tagging process.

[0074] Therefore, it greatly reduces the difficulty of supervising lock-up and tagging, realizes comprehensive intelligent monitoring of lock-up and tagging, and improves the safety of equipment operation.

[0075] In this embodiment, the light alarm can be triggered by the device's own signal indicator lights or by the indicator lights set by the device itself. The alarm format can be, for example, a red light indicating that the tag is not locked, a green light indicating that the tag is locked, and a yellow light indicating standby status. The format can be set freely, and this embodiment does not impose any specific limitations. The voice module alarm can use an existing voice module with an integrated speaker to set up sound reminders and alarms.
