Description

Technical Field

[0001] The embodiments of the present invention relate to the field of chemical industry, and in particular to a safety unlocking system, a blind plate and a structure of a blind plate valve. Background Art

[0002] Blind plates, also called flange covers, are mainly used to completely isolate production media to prevent production from being affected or even causing accidents due to the loose closure of the shut-off valve. Blind plates are generally installed at the pipe mouth of the equipment, before and after the shut-off valve, or between two flanges. Due to the good sealing performance of blind plates, they are generally used as a reliable isolation method for systems that need to be completely isolated. During maintenance, a blind plate is inserted between the two flanges and locked with bolts to completely isolate the production medium in the pipeline from the maintenance pipeline area. At present, the blind plate locks on the market are composed of a lock body and an external padlock. When installing on site, first install the lock body on the flange by adjusting the lock body telescopic rod, and then lock the lock body with an external padlock. When blind plate operation is required, first unlock it by key or fingerprint, remove the external padlock, and then disassemble and install the lock body to perform blind plate operation.

[0003] However, the disadvantage of pure mechanical locks is that keys need to be brought with them for each operation, which can easily lead to key loss on site. In addition, it is impossible to bind people to locks and trace who performed the operation. At present, there is a lack of effective control measures for blind plates in maintenance. When locking or unlocking blind plates, there is no authority identification, and it is impossible to know who operated the blind plates. It often happens that uninformed personnel mistakenly remove blind plates, causing the medium to flow to the maintenance pipeline area or leak to the outside world, causing property losses and even major personal safety accidents.

[0032] One or more embodiments are exemplarily described by the pictures in the corresponding drawings, and these exemplary descriptions do not constitute limitations on the embodiments.

[0034] Figure 2 It is another structural schematic diagram of a security unlocking system provided by an embodiment of the present application. DETAILED DESCRIPTION

[0035] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0036] In order to facilitate understanding of the embodiments of the present application, relevant contents about blind plate extraction and plugging are first introduced here.

[0037] Blind plate plugging operation is one of the eight special operations in petrochemical enterprises. During the operation, the medium in the equipment (pipeline) is often difficult to clean thoroughly, and the pressure in the pipeline is sometimes difficult to release to normal pressure. According to the different hazardous characteristics of the medium, corresponding hazards such as poisoning and suffocation, scalding (chemical burns, scalds or frostbite), fire and explosion may occur; careless operation or misoperation of the tools used may lead to accidents such as object impact, mechanical injury, lifting injury, etc.; working on the pipe gallery or high platform also has the risk of falling from height.

[0038] The petrochemical industry has clear safety management regulations for energy isolation operations, but there are still defects in the real-time status perception of conventional fixed blind plates. For the use of flanges and valves in key positions during temporary maintenance, tank cleaning and short-term start-up and shutdown, the position and blockage status of the blind plate cannot be perceived in real time and sent back to the background system, and anyone can operate the blind plate at will, and there is no technical restriction.

[0039] Blind plates, also called flange covers, are mainly used to completely isolate production media to prevent production from being affected or even causing accidents due to the shut-off valve not being closed tightly. Blind plates are generally installed at the pipe mouth of the equipment, before and after the shut-off valve, or between two flanges. Due to the good sealing performance of blind plates, they are generally used as a reliable isolation method for systems that need to be completely isolated. During maintenance, a blind plate is inserted between the two flanges and locked with bolts to completely isolate the production medium in the pipeline from the maintenance pipeline area. However, at this stage, there is a lack of effective control measures for blind plates in maintenance. When locking or unlocking the blind plates, there is no authority identification, and it is impossible to know who has operated the blind plates. It often happens that uninformed personnel mistakenly remove the blind plates, causing the medium to flow to the maintenance pipeline area or leak to the outside world, causing property losses or even major personal safety accidents.

[0040] The existing technical solution is to add a padlock to the blind plate lock. During on-site installation, first adjust the telescopic rod of the lock body, install the lock body on the flange, and then lock the lock body with a padlock. The padlock can be a mechanical padlock or a smart padlock. When blind plate operations are required, first unlock it with a key, fingerprint, or Bluetooth, remove the padlock, and then disassemble and assemble the lock body to perform blind plate operations. The disadvantage of a pure mechanical lock is that you need to bring a key for each operation, and it is easy for the key to be lost on site. It is also impossible to bind people to the lock, and it is impossible to trace who performed the operation. There are no safety measures, and anyone can operate it as long as they have the key. If an electronic lock such as a fingerprint lock is used, the standby time is limited due to the limited battery capacity of the electronic lock. In addition, in this way, the lock body and the lock are separated, and the lock cannot be bound to the lock body on site.

[0041] In order to solve the above-mentioned technical problem of being unable to trace the unlocking operation, the present invention proposes a safety unlocking system, a blind plate and a blind plate valve structure. The implementation details of the safety unlocking system of this embodiment are described in detail below. The following content is only the implementation details provided for ease of understanding and is not necessary for the implementation of this solution.

[0042] Embodiment 1:

[0043] The safety unlocking system of this embodiment can be applied to blind plates, and its specific structure can be as follows: Figure 1 As shown, the system includes a control chip, an identity information acquisition module, a verification information acquisition module, a transmission module and a communication module respectively built into the blind plate, and the identity information acquisition module, the verification information acquisition module, the transmission module and the communication module are respectively electrically connected to the control chip; wherein,

[0044] The identity information acquisition module is used to acquire the identity information of the operator and send the identity information to the control chip; the identity information is used to identify the operator;

[0045] The control chip is used to obtain device identification information, and send the device identification information and the identity information to the communication module; the device identification information is used to identify the blind plate;

[0046] The communication module is used to receive the device identification information and the identity information, and send the device identification information and the identity information to the backend;

[0047] The communication module is used to receive unlocking information generated by the background verifying the identity information and obtaining a legal result, and send the unlocking information to the control module; wherein the communication module of the security unlocking system that receives the unlocking information is determined by the background according to the device identification information;

[0048] The verification information collection module is used to collect the verification information input by the operator and send the verification information to the control module;

[0049] The control module is used to generate an unlocking control command when the verification information matches the unlocking information, and send the unlocking control command to the transmission module; wherein the verification information matching the unlocking information is determined by the unlocking information sent by the backend to the operator's mobile terminal;

[0050] The transmission module is used to control the locking structure used to lock the blind plate to unlock in response to the unlocking control command.

[0051] Specifically, the blind plate is provided with a shell, the shell is provided with a cavity, the control chip, the identity information collection module, the verification information collection module, the transmission module and the communication module are provided in the cavity, the identity information collection module collects the identity information of the operator, the identity information is used to distinguish different operators, and plays the role of identifying the operator, which can be the staff's unique work card number, ID card number, face information, iris information, voice and color information, etc. The control chip obtains the device identification information, such as the device ID number, and the unique blind plate and the safety unlocking system in the blind plate can be determined according to the device identification information. The control chip sends the device identification information and identity information to the communication module, and the communication module can communicate with external electronic devices, such as interacting with the background that manages each blind plate, and the communication module can communicate with the background wirelessly / wired, and the communication module sends the device identification information and identity information to the background. The background remotely controls the safety unlocking system in each blind plate. The background stores the information of each legal person. The legal person information is the identity information of the legal operator. The background can configure the legal person information for the safety unlocking system in each blind plate, and configure the staff with unlocking operation authority for the safety unlocking system in each blind plate, so that the management of the safety unlocking system in each blind plate is more flexible, and the legal operators of each blind plate can be adjusted at any time in the background, which is convenient for unified management. The background can determine the legal person information of the blind plate according to the device identification information, and check whether the identity information exists in the legal person information for verification. When the legal person information contains the identity information and a legal result is obtained, it means that the operator has the authority to unlock the blind plate, generates unlocking information, and sends the unlocking information to the communication module of the safety unlocking system of the blind plate identified by the device identification information and the mobile terminal of the operator. The communication module sends the unlocking information to the control module.

[0052] The operator inputs verification information to the verification information collection module according to the unlocking information. The verification information collection module can be a touch panel, a password button device, a sound collector, or an information receiving module that communicates with the operator's mobile terminal. The operator can input verification information by touching the touch panel, by pressing the password button, by speaking to the sound collector, or by inputting verification information to the information receiving module through the mobile terminal. The verification information collection module sends the collected verification information to the control module. The control module performs a preset matching check on the verification information and the unlocking information. The preset matching check is determined according to the relationship between the unlocking information and the matching verification information, and determines whether the verification information and the unlocking information match. When the verification information and the unlocking information match, it indicates that the operator can receive the unlocking information sent by the background, and then generates an unlocking control command. When the relationship between the unlocking information and the matching verification information is that the unlocking information and the matching verification information are the same, the preset matching check is to determine whether the unlocking information and the verification information are the same. When the unlocking information and the verification information are the same, it indicates that the unlocking information and the verification information match. When the unlocking information and the verification information are different, it indicates that the unlocking information and the verification information do not match. When the relationship between the unlocking information and the matching verification information is a mathematical function relationship between the matching verification information and the unlocking information, the legitimate operator knows the mathematical function relationship, and thus can calculate the matching verification information based on the mathematical function relationship and the unlocking information. At this time, the preset matching verification is to determine whether the unlocking information and the verification information conform to the mathematical function relationship. When the unlocking information and the verification information conform to the mathematical function relationship, it means that the unlocking information and the verification information match. When the unlocking information and the verification information do not conform to the mathematical function relationship, it means that the unlocking information and the verification information do not match.

[0053] The locking structure can adopt an existing mechanical lock structure. The transmission module responds to the unlocking control command and drives the output end of the transmission module to move, so that the output end of the transmission module and the input end of the locking structure are in an unlocked mechanical structure state, so that the locking structure loosens the blind plate, allowing the blind plate to move. The locking structure and the transmission module can be connected by clamping to limit the movement of the blind plate, so as to achieve locking of the blind plate. For example, a groove is provided at the input end of the locking structure. When the blind plate needs to be locked, the transmission module drives the card strip to be inserted into the groove, and the groove limits the movement of the card strip, thereby limiting the movement of the blind plate to achieve locking. When the transmission module responds to the unlocking control command, the card strip is retracted to prevent the groove from limiting the movement of the card strip, so that the blind plate can move.

[0054] The security unlocking system of this embodiment includes a control chip, an identity information collection module, a verification information collection module, a transmission module and a communication module which are respectively built into the blind plate. No external lock is required. The identity information collection module, the verification information collection module, the transmission module and the communication module are respectively electrically connected to the control chip. The identity information collection module is used to collect the identity information of the operator. For example, a fingerprint recognition device collects the fingerprint information of the operator as the identity information and sends the identity information to the control chip. The identity information is used to identify the operator. Different operators have different identity information. The control chip is used to obtain device identification information and send the device identification information and the identity information to the communication module. The device identification information is used to identify the blind plate. Different blind plates have different device identification information. The communication module is used to receive the device identification information. The device identification information and identity information are sent to the background, and the background verifies the identity information to obtain the verification result. When the verification result is a legal result, the unlocking information is generated, and the unlocking information is sent to the communication module of the blind plate identified by the device identification information and the operator's mobile terminal. The communication module is used to receive the unlocking information and send the unlocking information to the control module. The verification information collection module is used to collect the verification information input by the operator and send the verification information to the control module. The control module is used to generate an unlocking control command when the verification information and the unlocking information match. The verification information that matches the unlocking information is the unlocking information sent by the background to the operator's mobile terminal. The unlocking control command is sent to the transmission module, and the transmission module is used to respond to the unlocking control command to control the locking structure used to lock the blind plate to unlock. As a result, there is no need for the operator to carry a key, and there is no need to worry about the possibility of unlocking by someone other than the legal staff due to the loss of the key. Before unlocking, the identity information is first collected through the identity information collection module, and the background verifies whether the identity information has the authority to open this blind plate, so that the operator and the blind plate are bound. When the staff has the authority to unlock the blind plate, the unlocking information is sent to the communication module and the operator's mobile terminal to prevent uninformed personnel from mistakenly removing the blind plate and causing the medium to flow to the maintenance pipeline area or leak to the outside world, causing property losses or even major personal safety accidents, thereby improving the safety of unlocking. After the operator receives the unlocking information, the verification information is input into the verification information collection module according to the unlocking information. The verification information collection module sends the verification information to the control module. The control module verifies the verification information and the unlocking information received from the background. When the verification information and the unlocking information are the same, the verification is passed, and the control module controls the transmission module to drive the locking structure to unlock. In this way, the unlocking operation can be traced back and the identity information of the staff can be queried, making the control means more effective.

[0055] In one embodiment, the unlocking information is randomly generated by the background.

[0056] In this embodiment, the randomly generated unlocking information is not easily leaked to other users. Only the blind plate corresponding to the device identification information and the mobile terminal of the operator whose identity information has been verified can receive the unlocking information, which improves the security of the unlocking information. Moreover, the unlocking information generated each time after the identity information is verified is different, so that the generated unlocking information can only be used for the current time, which improves the security of the unlocking information.

[0057] In one embodiment, the communication module further includes a wake-up module electrically connected to the control chip, the wake-up module is used to communicate with the mobile terminal, respond to the wake-up command sent by the mobile terminal, start the control chip; send the device identification information and the identity information to the background, receive the unlocking information, and send the unlocking information to the control chip;

[0058] and / or,

[0059] The communication module also includes a transmission module electrically connected to the control chip, the transmission module is used to communicate with the background, send device information to the background, receive background commands sent by the background, and send the background commands to the control chip so that the control chip controls the module to be controlled.

[0060] In this embodiment, when the security unlocking system is not in use, the security unlocking system enters a closed / dormant state to save power. The wake-up module can be connected to the operator's mobile terminal for communication. The operator searches for the wake-up module through wireless communication, connects to the wake-up module, responds to the wake-up command sent by the mobile terminal, and the wake-up module transmits a successful connection signal to the control chip. After the control chip receives the successful connection signal, it starts the security unlocking system, for example, starts the identity information collection module to collect the operator's identity information. The wake-up module can also send device identification information and identity information to the background, receive unlocking information, and send the unlocking information to the control chip to achieve interactive communication between the control chip and the background. Communication with the background can also be achieved through a transmission module, which sends device identification information and identity information to the background, receives unlocking information, and sends the unlocking information to the control chip to achieve interactive communication between the control chip and the background. The transmission module can also send device information to the background. The device information is real-time information reflecting the status of the device, such as remaining power information and equipment fault information, so that the background can monitor whether the blind plate can be used normally. The transmission module can also receive background commands sent by the background, and send the background commands to the control chip so that the control chip controls the module to be controlled. The module to be controlled is determined according to the control object of the background command. For example, the background command controls the power supply module to enter the shutdown state to save power, then the module to be controlled is the power supply module.

[0061] In one embodiment, the wake-up module is a short-range wireless communication module.

[0062] In this embodiment, in order to facilitate the operator to connect to the wake-up module, the wake-up module is a short-range wireless communication module. The operator close to the blind plate can connect to the wake-up module through a mobile terminal. For example, the wake-up module is a Bluetooth communication module, a Wifi communication module or an NFC communication module, and the operator can connect to the wake-up module through the mobile terminal.

[0063] In one embodiment, the identity information acquisition module includes at least one of a fingerprint acquisition module, a face acquisition module, an eye acquisition module and an information code scanning module, wherein the information code scanning module is used to scan the information code containing the identity information of the operator.

[0064] In this embodiment, in order to accurately identify the identity of the operator, the identity information collection module includes a fingerprint collection module, a face collection module, an eye collection module and an information code scanning module. The fingerprint collection module collects fingerprint information as identity information, the face collection module collects face information as identity information, and the eye collection module collects eye information as identity information. The information code scanning module can be, for example, a QR code scanner, which scans an information code containing the operator's identity information, such as a QR code containing an ID number. The information code is stored in the operator's mobile terminal so that it is not easy to miss and carry with you. The control chip decodes the information code to obtain the identity information.

[0065] In one embodiment, the verification information collection module includes a password input device and / or an information code scanning device, wherein the password input device is used to collect the verification information input by the operator, and the information code scanning device is used to scan the information code containing the verification information displayed by the operator.

[0066] In this embodiment, the verification information acquisition module can be a password input device, such as a password key device, and the operator presses a key to input the verification information. The unlocking information of the mobile terminal sent to the operator by the background can be displayed on the display screen of the mobile terminal in the form of a QR code. The operator aligns the QR code on the display screen with the information code scanning device, and the information code scanning device scans the QR code, and the control information decodes the QR code to obtain the verification information. When both the identity information acquisition module and the verification information acquisition module use the information code scanning device, the same information code scanning device can be used to save equipment costs. The operator presses the switching button to control the information code scanning device to be used as the identity information acquisition module / verification information acquisition module.

[0067] In this embodiment, the security unlocking system further has a power supply module, which is electrically connected to the control chip and is used to supply power to the control chip, the verification information collection module, and the identity information collection module.

[0068] Embodiment 2:

[0069] The security unlocking system of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities. The specific process can be as follows: Figure 2 As shown, including:

[0070] The entire security unlocking system includes a power supply module, a fingerprint module, a password key group, a control chip, a locking structure, a transmission device, and a transmission module. The power supply module, the fingerprint module, the password key group, the control chip, the transmission device, and the transmission module are placed in the cavity; the locking structure is independent of the cavity. The cavity refers to the outer shell of the blind plate.

[0071] The power supply module is connected to the control chip through the circuit board. The password key group and the fingerprint module are connected to the input of the control chip, and the output of the control chip is connected to the transmission device. The transmission device controls the internal gear reduction motor, and the gear reduction motor pushes the metal rod to rise and fall through the rack. The metal rod is part of the transmission device. The gear reduction motor drives its gear to rotate, and the gear meshing rack moves linearly. Since the rack is connected to the metal rod, it drives the metal rod to move linearly. When the reduction motor pushes the metal rod to extend to a certain extent, the metal rod will mesh with the rack on the locking structure. When the metal rod moves forward, it will touch the rack on the locking structure, and then it will be coupled, thereby limiting the sliding of the entire cavity along the locking rod. At the same time, the control chip is also connected to the Bluetooth module, and communicates with the handheld device through the Bluetooth module. In addition, the control chip is also connected to the transmission module, and the device information is sent to the background through the transmission module, and the background command is also sent to the control chip through the transmission module. The transmission module is a communication module such as a 4G module or a 5G module.

[0072] When the operator receives a blind plate operation task, he arrives at the task site and first wakes up the device via Bluetooth. Then the operator enters the fingerprint on the fingerprint entry interface on the device. After receiving the fingerprint entry information, the device passes the fingerprint information and device ID number to the Bluetooth APP, and the Bluetooth APP passes the fingerprint information and device ID number to the background. The background first matches the fingerprint information with the fingerprint in the database; if the fingerprint identification matches the legitimate operator, the background randomly generates an operation password. The device ID number is the ID number of the blind plate device. The function of the device ID number is to determine which blind plate to send the password to, and send this password to the device and APP at the same time. Sent to this blind plate device, and the APP on the operator's handheld device. The operator receives the password on the APP and enters the password into the blind plate. The blind plate detects whether the password is consistent with the password it received. If the fingerprint match fails, the background sends an alarm message to the device and APP. After receiving the operation password, the operator enters the password into the device through the password key group. The device verifies the password and the password sent by the platform. If they are consistent, the verification is passed. The control chip controls the reduction motor to retract the mechanical rod to unlock. The mechanical rod is the metal rod pushed by the front rack. Otherwise, the lock is maintained, and the device sends an on-site alarm and a remote alarm. After the operation is completed, the blind plate device will transmit the operation record and operation results to the background.

[0073] The fingerprint module is used to identify whether the operator has the authority to operate the blind plate, while the password group is used to perform the opening and closing operations of the blind plate to ensure the safety of the operation. Fingerprint recognition is placed in the background instead of locally, which can facilitate the maintenance of the fingerprint database. This solution realizes double unlocking, which is more convenient to unlock and solves the problem that the user's keys are inconvenient to carry and easy to miss and lose; the fingerprint and password are integrated, and remote identification and authorization are performed through the background, realizing one lock and one password, which is different each time, making it safer to use and more convenient to maintain.

[0074] In this embodiment, the metal rod is part of the transmission device. The locking rod is part of the locking structure. The blind plate is clamped between the flanges and the flanges are clamped by the cavity and the fixing seat. The locking rod is part of the locking structure, and it is separate from the cavity and not connected. When the metal rod of the cavity is coupled with the rack on the locking rod, the cavity of the blind plate is fixed. In this embodiment, the information sent to the background includes the fingerprint of the operator and the blind plate lock device ID. When the fingerprints match, the password is sent to the operator's mobile phone and the transmission device of the blind plate lock.

[0075] In this embodiment, the fingerprint method is used for authority identification. The operator is bound to the device, and only qualified people can operate it, which avoids arbitrary operation by unrelated personnel, and each operation is recorded and traced back. The password group method is used to operate the switch valve for the safety of on-site operations. When the platform receives the switch operation request, the platform first judges the status of the blind plate in front and behind the node in the background. If the blind plate in front and behind the node is in a safe state, the password is issued to the operator for operation; if the blind plate in front and behind the node is in a dangerous state, the platform sends an alarm prompt to the operator, prompting the operator that the switch operation cannot be performed at present, otherwise it will cause a dangerous accident. The lock function is integrated into the blind plate device, which solves the problem that the user's key is inconvenient to carry and easy to lose, and realizes the binding of the lock and the blind plate, realizing one lock and one blind plate. The transmission scheme used is the 4G communication module, and the other mobile communication technologies + short-range wireless transmission technologies can replace this communication module scheme. This embodiment uses fingerprint recognition, and other recognition methods such as face recognition can replace this positioning scheme.

[0076] The safety unlocking system of this embodiment has the following advantages:

[0077] 1. Intelligent blind plate lock integrates the blind plate equipment with the lock, solving the problem of the original lock and equipment being separated. It effectively solves the problem that the original mechanical lock needs to carry many keys every time it is operated, and the keys are easily lost on site. In addition, the original mechanical lock cannot realize the binding between people and locks, and it is impossible to trace who performed the operation. There are no safety measures. As long as there is a key, anyone can operate the equipment.

[0078] 2. The smart blind lock uses fingerprints to identify permissions. Bind the operator to the device. When the operator's fingerprint and the device ID of the smart blind lock are sent to the background, the background will identify them. Only when the operator and the designated blind lock meet the conditions can the operation be performed, which avoids irrelevant personnel from performing arbitrary operations, and each operation is recorded and traced back.

[0079] 3. The use of password groups to operate the valve switch is for the safety of on-site operations. When the platform receives a switch operation request, it first determines the status of the blind plates in front and behind the node in the background. If the blind plates in front and behind the node are in a safe state, the password is sent to the operator for operation; if the blind plates in front and behind the node are in a dangerous state, the platform sends an alarm to the operator, prompting the operator that the switch operation cannot be performed at present, otherwise it will cause a dangerous accident.

[0080] In this embodiment, there is no padlock device. By installing a corresponding circuit structure in the lock body, a built-in latch transmission device and Bluetooth are used to achieve functions similar to those of an electronic lock. At the same time, the latch transmission device is used to detect the state of the blind plate in real time, and identity authentication can be achieved through Bluetooth combined with the latch transmission structure. The blind plate is unlocked by a fingerprint + password dual locking method, and the blind plate operation is bound to the operator, which effectively solves the problem of the media flowing to the maintenance pipeline area or leaking to the outside world due to the accidental removal of the blind plate, causing property losses or even major personal safety accidents.
