Description

Technical Field

[0001] The present application relates to the technical field of electronic locks, and in particular to a safety lock system. Background Art

[0002] In the application of swing shear production lines in the steel industry, it is crucial to ensure operational safety and production efficiency. As the core component of steel plate shearing processing, the stability and reliability of the swing shear equipment are directly related to the overall efficiency of the production line and product quality. Therefore, maintenance work is not only the key to extending the life of the equipment, but also an important measure to prevent safety accidents and ensure personnel safety.

[0003] Although the current mechanical lock security mechanism provides basic locking functions to a certain extent, its limitations are increasingly prominent in the face of complex and ever-changing maintenance scenarios. First, the mechanical lock has a simple structure and lacks identity authentication and permission management functions, which means that any maintenance personnel holding the same type of lock can unlock any locked device, which undoubtedly increases the risk of misoperation and security. Second, the use of mechanical locks relies on manual management, which is prone to forgetting, losing or misusing locks, causing unnecessary confusion and delays in the maintenance process.

[0004] More importantly, since each maintenance staff member has different task assignments, professional skills and work progress, the current mechanical locking solution cannot effectively track and manage the individual's work progress, nor can it ensure that only specific personnel can unlock specific equipment at a specific time. This may cause equipment that has not completed maintenance to be mistakenly locked, leading to serious safety accidents.

[0005] Therefore, there is an urgent need for a safety lock system to solve the above problems. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the embodiments of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0044] Combination Figure 1 and Figure 3As shown, a safety lock system includes an information acquisition module, a storage module, a matching module, a locking module and an error reporting module. The output end of the information acquisition module is electrically connected to the input end of the storage module, and is used to collect the biometric information of the staff. The input end of the storage module is electrically connected to the output end of the information acquisition module, and is used to store the biometric information collected by the information acquisition module. The input end of the matching module is electrically connected to the output end of the storage module, and is used to match and process the biometric information stored in the storage module. The input end of the locking module is electrically connected to the output end of the matching module, and the input end of the error reporting module is electrically connected to the output end of the locking module, and is used to respond to the locking module.

[0045] In the above scheme, the information collection module usually includes biometric technology equipment, such as fingerprint scanners, facial recognition cameras, etc., which are used to collect biometric information of staff members who attempt to access the swing shearing equipment. For example, when a maintenance staff member is ready to unlock the swing shearing equipment, he / she needs to place his / her finger on the fingerprint scanner or face the facial recognition camera to complete the collection of biometric information.

[0046] The storage module is responsible for storing the biometric information of all personnel authorized to access the swing shearing equipment. This information is entered when the system is initialized or when personnel are authorized, and is stored in a secure, encrypted database. When the information acquisition module collects the biometric information, it will be sent to the storage module for preparation before comparison.

[0047] The matching module is responsible for matching the biometric information collected by the information collection module with the information stored in the storage module. If the collected information matches the stored information, it means that the person trying to access is authorized, and the matching module will send a confirmation signal to the locking module. If it does not match, no confirmation signal will be sent, or a rejection signal will be sent.

[0048] Based on the output of the matching module, the locking module controls the locking state of the swing shearing device. If a confirmation signal is received, the locking module will unlock the device and allow the operator to operate. If no confirmation signal is received or a rejection signal is received, the locking module will keep the device locked or trigger the error module.

[0049] When the locking module keeps the device locked due to not receiving a confirmation signal, or fails to unlock the device due to receiving a rejection signal, the error reporting module will be activated. The error reporting module can provide error information to the staff through sound, light or display, such as "unauthorized access", "biometric information does not match", etc., and may record the details of the attempted access for subsequent analysis.

[0050] This application uses biometric technology to enable the security lock system to ensure that only authorized staff can access the swing shear equipment and control the locking and unlocking status of the swing shear equipment, greatly reducing the risk of misoperation and illegal access. The system automates the identity authentication and permission management process, reduces the need for manual intervention and paper records, and improves management efficiency. The system can record detailed information for each access attempt, including time, location, identity of the person attempting access, etc., providing valuable data support for security incident investigations. For authorized staff, biometric technology is more convenient than traditional mechanical locks or passwords, and there is no need to carry extra keys or remember complex passwords.

[0051] For example, after the maintenance personnel enter their personal information (name, photo, face information) in advance, they can operate the face recognition device when they need to enter the device. After pressing the lock button on the screen, the device recognizes the person. If the match is successful, the scanned person's information will be displayed on the device until the person exits the device and performs the unlocking operation. The device can display the locking information of multiple people, and only the person can unlock his or her own lock status, and other people cannot unlock it, avoiding the possibility of security risks.

[0052] The safety lock system in the present application also includes a linkage module. The input end of the linkage module is electrically connected to the output end of the locking module, and the output end of the linkage module is electrically connected to the input end of the external device. Among them, the linkage module includes a grating, an infrared sensor and a scanning radar. The grating is fixedly set at the entry position of the equipment on the operating side of the stacking area, and the radiation range of the grating covers the surrounding side of the equipment. The infrared sensor is fixedly set in the middle of the outer side of the equipment. The scanning radar is fixedly set at the outer top of the equipment. The output ends of the grating, infrared sensor and scanning radar are electrically connected to the output end of the locking module.

[0053] In the above scheme, the light barrier is fixedly set at the entry position of the equipment on the operating side of the palletizing area, and its radiation range covers the surrounding side of the equipment. The light barrier detects whether there are objects or people entering its monitoring area by emitting and receiving light beams. When the light barrier detects that an object or person blocks the light beam, it immediately sends a signal to the locking module, which determines whether to trigger an alarm or lock the equipment based on the preset logic.

[0054] The infrared sensor is fixedly installed in the middle of the outer side of the equipment to detect changes in infrared radiation around the equipment. When a person or object approaches the equipment, its infrared radiation will change, and the infrared sensor can capture this change and send a signal to the locking module. The scanning radar is fixedly installed on the outer top of the equipment, with a wider monitoring range and higher accuracy. It can scan the environment around the equipment by emitting and receiving electromagnetic waves, and generate three-dimensional images or point cloud data. When the scanning radar detects that an abnormal object or person is approaching the equipment, it will immediately send an alarm signal to the locking module, and the locking module will take corresponding safety measures according to the preset rules. For example, it can perform a decreasing emergency brake on the swing shearing equipment or send a physical signal to remind the maintenance personnel to suspend the operation of the corresponding equipment.

[0055] By integrating gratings, infrared sensors and scanning radars, the system can provide multiple security guarantees and effectively prevent unauthorized access and potential security risks. The linkage module can monitor environmental changes around the device in real time and quickly send signals to the locking module when abnormal conditions are detected, thereby improving the response speed and safety of the system. The coordinated work of gratings, infrared sensors and scanning radars makes the system's monitoring range wider, covering the device and its surrounding areas, and effectively preventing safety hazards in blind spots. By integrating advanced sensor technology and data processing algorithms, the system can automatically analyze monitoring data and take corresponding safety measures according to preset rules, improving the intelligence and automation level of the system.

[0056] The safety lock system in the present application also includes an autonomous control module. The input end of the autonomous control module is electrically connected to the output end of the matching module, and its output end is electrically connected to the output end of the locking module. Among them, the autonomous control module includes an unlocking unit, a locking unit and a master control unit. The input ends of the unlocking unit and the locking unit are electrically connected to the output end of the matching module. And their output ends are electrically connected to the input end of the master control unit. The output end of the master control unit is electrically connected to the input end of the locking module and the linkage module.

[0057] In the above scheme, the master control unit is responsible for receiving requests from the unlocking unit and the locking unit, and judging whether these requests are valid according to the system's security policy and preset rules. If the request is valid, the master control unit will send corresponding instructions to the locking module and the linkage module to control the locking state of the device and the working state of the linkage module.

[0058] When the matching module confirms that the staff member trying to access is authorized, it sends an unlock signal to the unlocking unit. After receiving the signal, the unlocking unit sends a request to the main control unit to unlock the swing shear device. After confirming that the request is valid, the main control unit sends an unlock instruction to the locking module, and the locking module performs the unlocking operation to allow the staff member to access the device.

[0059] When the matching module confirms that the staff member who attempts to access is not authorized, or the staff member completes the operation and leaves the equipment, it will send a locking signal to the locking unit. After receiving the signal, the locking unit will also send a request to the main control unit to lock the swing shear device. After confirming that the request is valid, the main control unit will send a locking instruction to the locking module, and the locking module will perform the locking operation to ensure the safety of the equipment.

[0060] By introducing an autonomous control module, the system can automatically perform unlocking and locking operations according to the output results of the matching module without manual intervention, thereby improving the automation level of the system. The autonomous control module can flexibly control the status of the locking module and the linkage module according to the system's security policy and preset rules to meet the security requirements in different scenarios. Since the autonomous control module can independently determine the validity of the request and quickly send instructions to the locking module and the linkage module, the response speed of the system is significantly improved. Through the precise control of the locking module and the linkage module by the autonomous control module, the system can more effectively prevent unauthorized access and potential security risks, and improve overall security.

[0061] The error reporting module includes a sound generator and a light generator. The input ends of the sound generator and the light generator are electrically connected to the output end of the locking module, and the output ends thereof are fixedly connected to the output end of the autonomous control module.

[0062] In the above scheme, when the sound generator receives the alarm signal from the locking module, the sound generator will immediately start and emit a preset alarm sound. This sound usually has a specific frequency and pitch so that the operator can quickly identify which type of alarm it is. The output end of the sound generator is also electrically connected to the output end of the autonomous control module, which means that when the autonomous control module performs certain specific operations (such as forced unlocking, emergency shutdown, etc.), it can also send a signal to the sound generator to emit a corresponding prompt sound.

[0063] When the light generator receives the alarm signal from the locking module, the light generator will light up a preset alarm light. This light usually has a specific color and flashing pattern so that the operator can quickly identify the type and severity of the alarm. The output end of the light generator is also electrically connected to the output end of the autonomous control module, so that when the autonomous control module performs a specific operation, it can also control the state of the light generator to provide visual feedback.

[0064] By providing both sound and light alarms, the system can attract the operator's attention more quickly when errors or abnormal situations occur, thereby improving the timeliness and effectiveness of the alarm. When the system detects a potential safety risk, the sound generator and the light generator can immediately sound an alarm to remind the operator to take necessary measures to avoid accidents, thereby improving overall safety. Since the output ends of the sound generator and the light generator are electrically connected to the output ends of the autonomous control module, the autonomous control module can flexibly control the states of these two components according to the needs of the system to adapt to different application scenarios and safety requirements.

[0065] An installation component is fixedly arranged between the grating and the device. The installation component includes a base 10, a fixed block 11 and a pre-tightening member 12. The base 10 is fixedly arranged on the operating side of the stacking area of ​​the device, and a slide groove 101 is provided on the side away from the device, and the length direction of the slide groove 101 is consistent with the height direction of the device. Two fixed blocks 11 are vertically arranged at both ends of the base 10 relative to one side of the device, and their bottoms are slidably arranged in the slide groove 101. The two fixed blocks 11 can approach or depart from each other in the slide groove 101 along the plate surface of the base 10. The pre-tightening member 12 is movably arranged at the bottom of the base 10, and its two ends are respectively fixed to the bottom of the block 11.

[0066] In the above scheme, the base 10 is first fixedly set on the operating side of the stacking area of ​​the equipment, which is the basis of the entire installation assembly. A slide groove 101 is opened on the side of the base 10 away from the equipment, and the length direction of the slide groove 101 is consistent with the height direction of the equipment, which provides space for the sliding adjustment of the fixed block 11. Two fixed blocks 11 are vertically set at both ends of the base 10 relative to one side of the equipment, and their bottoms are slidably set in the slide groove 101. This means that the fixed block 11 can be slid and adjusted along the length direction of the slide groove 101 (i.e. the height direction of the equipment), so that it can flexibly adapt to gratings of different sizes or installation heights. The pre-tightening member 12 is movably set at the bottom of the base 10, and its two ends are respectively connected to the bottom of the two fixed blocks 11. The function of the pre-tightening member 12 is to pre-tighten the fixed block 11 to ensure that the fixed block 11 can be stably fixed in the slide groove 101 after being adjusted to a suitable position to prevent it from moving due to external force or vibration. When the fixed block 11 is adjusted to a suitable spacing to match the size of the grating, the grating can be installed between the two fixed blocks 11. At this time, the pre-tightening member 12 is further tightened to ensure a tight connection between the fixing block 11 and the grating to prevent the grating from shaking or shifting during use.

[0067] A light hole 102 is formed inside the base 10 on a side away from the slide slot 101 , part of the hole cavity of the light hole 102 is connected to the groove cavity of the slide slot 101 , the outer wall of the preload member 12 is slidably connected to the inner wall of the light hole 102 , and the size of the light hole 102 matches the size of the preload member 12 .

[0068] In the above scheme, the light hole 102 is designed inside the side of the base 10 away from the slide groove 101, and its size is adapted to the size of the preload 12, so that the preload 12 can slide smoothly in the light hole 102 without excessive resistance or jamming. When it is necessary to adjust the position of the fixed block 11, the operator can operate the preload 12 (such as rotating the handle, pulling the pull rod, etc.) to make it slide in the light hole 102. Since the size of the light hole 102 is adapted to the size of the preload 12, the sliding of the preload is smooth and controllable. As the preload 12 slides in the light hole 102, it will apply a thrust or a pull force to the two fixed blocks 11, so that they are close to or away from each other along the length direction of the slide groove 101. The operator can adjust the spacing between the fixed blocks 11 as needed to adapt to gratings of different sizes. After the fixing block 11 is adjusted to a suitable position, the operator can further tighten the pre-tightening member 12 (such as using fasteners such as bolts and nuts) to ensure that the fixing block 11 is stably fixed in the slide groove 101. At this time, the outer wall of the pre-tightening member 12 will fit tightly with the inner wall of the light hole 102 to prevent it from moving due to external force or vibration. The pre-tightening member 12 in the present application is a deformable material, and its purpose is to use the reaction force generated by its own deformation to relatively fix the fixing block 11 and the base 10, so as to ensure a stable connection between the fixing block 11 and the base 10. Preferably, the pre-tightening member 12 in the present application is a compression spring.

[0069] The fixing block 11 is in an F-shaped structure as a whole, and the inner wall of the C-shaped structure at the top thereof abuts against the outer side surfaces of the two ends of the grating.

[0070] In the above scheme, the fixed block 11 of the F-shaped structure can be more effectively connected and fixed to the two ends of the grating, thereby improving the stability of the grating during the installation process. This design helps to prevent the grating from shaking or shifting due to external force or vibration during use. The C-shaped structure on the top of the fixed block 11 can be tightly against the outer surface of the grating, and this close contact enhances the reliability of the connection. Even under high load or harsh environment, the grating can maintain a stable and reliable connection. The fixed block 11 of the F-shaped structure has a certain elasticity and can adapt to gratings of different sizes. This makes the installation assembly more flexible and versatile, and can be applied to equipment of different models and specifications. Due to the design of the fixed block 11, the grating can be placed and fixed more easily, which reduces the complexity and difficulty of the installation process. The operator can complete the installation and commissioning of the grating more quickly, improving work efficiency.

[0071] The base 10 is provided with limit blocks 13 at both ends of the slide groove 101 in the groove length direction, and one side of the limit block 13 abuts against a side of the fixing block 11 away from the grating.

[0072] In the above scheme, the design of the limit block 13 enables the fixed block 11 to remain within a predetermined range during the sliding adjustment process, thereby ensuring the accuracy of the grating installation. This helps to avoid installation errors or damage and improves the reliability and stability of the entire safety lock system. By limiting the sliding range of the fixed block 11, the limit block 13 also protects the installation components from damage. This helps to extend the service life of the installation components and reduce the maintenance and replacement costs caused by excessive sliding. The design of the limit block 13 makes it easier for the operator to control the position and spacing of the fixed block 11, thereby simplifying the installation and debugging process of the grating. This improves work efficiency and reduces the difficulty of operation.
