Description

Technical Field

[0001] The present invention belongs to the technical field of grain storage, and relates to a granary limited space operation and intelligent access control system and a working method thereof. Background Art

[0002] Grain is a vital strategic national reserve material and is typically stored in confined spaces, such as granaries. Granaries are often plagued by pests and pathogens. Therefore, when pest infestation of grain (including finished grain, raw grain, oilseeds, dried potatoes, and seed grains) reaches a certain level, a sealed grain pile is filled with a specific amount of aluminum phosphide, calcium phosphide, zinc phosphide, or dichlorvos. These phosphides absorb moisture from the grain and the voids in the pile, generating a chemical reaction that releases highly toxic phosphine gas, effectively killing all pests and their eggs.

[0003] Disinfectants like phosphine are often highly corrosive and toxic. Grain consumes oxygen and produces large amounts of carbon dioxide during storage. Grain silos are often kept sealed during daily storage. When inspectors enter confined spaces, they run the risk of phosphine poisoning, oxygen deprivation, or carbon dioxide poisoning. Therefore, when inspectors enter silos, they must test for various gases inside to ensure the environment meets confined space standards.

[0004] 1. The common inspection method for existing granary gas detection smart lock systems is to install a diffusion-type gas detection device inside the granary. However, the limited detection range of this gas detection device is only 30 square meters, and the detected gas concentration data is not representative. In addition, the gas detection device installed in the granary is very likely to have its life shortened by highly corrosive gases such as phosphine.

[0005] Another approach is to install a gas detection device outside the silo and extract the gas through the gas pipe inside the silo. However, the gas detection device uses an electrochemical principle, which means that the effective life of the gas detection device is only 1-2 years. Placing a gas detection device in each silo will greatly increase the subsequent maintenance costs. Summary of the Invention

[0006] The purpose of the present invention is to address the above-mentioned problems existing in the existing technology and propose a granary limited space operation and intelligent access control system and its working method. The technical problem to be solved by the present invention is: how to improve the safety of warehousing operations and reduce the construction and maintenance costs of mechanical facilities.

[0007] The object of the present invention can be achieved by the following technical solutions: A method for operating and detecting an intelligent access control system in a limited space of a granary, characterized in that the method comprises:

[0008] S1. The user registers and their information is stored on the granary management platform and the access control host. Before entering the granary, the user needs to apply for a grain inspection work order on the granary management platform. After approval, the grain inspection work order is stored and sent to the access control host.

[0009] S2. The user arrives at the granary specified on the grain inspection work order. The face recognition device on the granary door detects the user's face and compares it with the face database. After the face ID is recognized, the user queries the information on the grain inspection work order in the order of the granary management platform after the access control host.

[0010] S3. When the access control host queries the grain inspection operation form, the air pump starts to collect gas from each detection point in the granary to the gas storage device located outside the door, and the user selects the grain inspection operation form on the access control host;

[0011] S4. The user installs the detector on the detection base connected to the gas storage device. The detector automatically starts when inserted into the detection base. The access control host detects the detector and successfully shakes hands with the detector. The access control host issues a gas detection control command, and the detector starts gas detection. The gas detection results are displayed on the access control host and uploaded to the granary management platform.

[0012] S5. When the gas detection result shows that it is safe, the unlock button on the access control host pops up. The user clicks the unlock button, the smart door unlocks and reports the switch status of the smart door to the access control host. The door host prompts the user that the door has been unlocked and asks the user to proceed. The information of the person entering the warehouse is stored in the granary management platform.

[0013] S6. After entering the granary, the user performs grain inspection according to the grain inspection operation sheet within the limited space of the granary;

[0014] S7. After the user completes the grain inspection operation in the limited space of the granary, the face is detected in front of the smart door and compared with the face database for recognition. After the face ID is recognized, the smart door is locked, and the user registers the grain inspection operation result on the user terminal, and the grain inspection operation form on the access control host is closed.

[0015] In this solution, the gas from each detection point in the granary is extracted into a gas storage device outside the granary through an air pump. This avoids the need to install a detector at each detection point, reduces the cost of detecting harmful gases, and prevents the detection instrument from being corroded for a long time in the granary, thereby increasing the service life of the detector. In addition, the inspectors can decide whether to enter the granary after knowing the concentration of harmful gases in the granary, and can take protective measures in advance, thereby improving the safety of users entering the granary to check grain.

[0016] In the above-mentioned working method of the intelligent access control system for limited space operation and detection in a granary, in S4, when the access control host fails to detect the detector within the specified time, the access control host falls back to the front of the smart door to detect the face and compare and identify the face from the face library; when the access control host fails to shake hands with the detector successfully, the user needs to reinstall the detector.

[0017] In the above-mentioned working method of the intelligent access control system for limited space operation and detection in a granary, in S5, when the gas detection result shows that the gas concentration exceeds the standard, the access control host prompts that the gas exceeds the standard, please ventilate, and it is not recommended to enter the granary, and a button pops up to ask whether to enter the warehouse. When the user selects no, the access control host returns to the home page. When the user selects yes, the unlock button on the access control host pops up, and the user clicks the unlock button.

[0018] In the above-mentioned working method of the intelligent access control system for limited space operation and detection in a granary, in S6, the user carries the detector into the granary to complete the operation.

[0019] The present invention also provides an intelligent access control system for limited space operation and detection in a granary, the system comprising: ventilation pipelines located at multiple positions in the granary and a gas storage device located outside the granary, the gas storage device being connected to an air pump outside the granary, the gas storage device being provided with a detection base for installing a detector, the detector being installed on the detection base and shaking hands with an access control host before starting to detect the gas in the gas storage device, the access control host being connected to a granary management platform, and the granary management platform storing the results of the gas detection.

[0020] In the above-mentioned intelligent access control system for limited space operation and detection of a granary, the system also includes: a user terminal, connected to the granary management platform, for user registration, filling in user information, and receiving a work order to apply for a grain inspection work order to the granary management software.

[0021] In the above-mentioned intelligent access control system for limited space operation and detection in a granary, the system further includes: a door lock installed on the intelligent door and connected to the access control host, for opening and closing the intelligent door.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. In the present invention, by applying the granary management platform, access control host and detector to the grain inspection operation and the granary intelligent access control system, the work efficiency of the user's grain inspection operation is greatly improved and the management requirements of the limited space operation of the granary are met.

[0024] 2. The present invention verifies whether the user has carried a detector by detecting whether there is a detector through the access control host, and then issues the step of executing gas detection after the access control host shakes hands with the detector, which can provide a second confirmation of the gas detection and avoid the step of starting the gas detection due to the user's misoperation.

[0025] 3. In the present invention, the gas detector is a portable design that is arranged outside the warehouse. Compared with arranging gas detection devices in each warehouse, it reduces the initial equipment investment and the subsequent replacement maintenance investment. At the same time, it can also prevent the detection instruments arranged in the warehouse from being corroded, thereby increasing the service life of the detector.

[0026] 4. In the present invention, after completing the pre-warehouse inspection, the gas detector can be removed from the detection base and carried into the warehouse by the operator. The real-time detection and real-time alarm of the warehouse gas concentration further ensure the safety of the user's warehouse entry operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 2 This is a flowchart of the specific working method of a granary limited space operation and intelligent access control system according to the embodiment of the present invention. DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0030] Example 1

[0031] This intelligent access control system for confined space operations and inspections in a granary mainly includes ventilation pipes located at multiple locations within the granary and a gas storage device located outside the granary. The gas storage device is connected to an air pump outside the granary. The gas storage device is provided with a detection base for installing a detector, and the detection base can also be installed at other locations connected to the gas storage device. After the detector is installed on the detection base and shakes hands with the access control host, it begins to detect the gas in the gas storage device. The granary management platform can be a cloud server or deployed locally. The access control host is connected to the granary management platform, and the granary management platform stores the results of gas detection. The system also includes user terminals, user terminals equipped with an APP connected to the granary management platform, or user terminals connected to the granary management platform through a web page. The system also includes some facial recognition devices and door locks connected to the access control host.

[0032] like Figure 1As shown, the working method of the granary gas detection intelligent access control system mainly includes the following steps: S1. The user registers and the user's information is stored in the granary management platform and the access control host. After receiving the work order, the user applies for a grain inspection work order on the granary management platform. The grain inspection work order is stored and sent to the access control host after approval;

[0033] S2. The user arrives at the granary specified on the grain inspection work order. The face recognition device on the granary door detects the user's face and compares it with the face database. After the face ID is recognized, the user queries the information on the grain inspection work order in the order of the access control host and then the granary management platform.

[0034] S3. When the access control host queries the grain inspection operation form, the air pump starts to collect gas from each detection point in the granary to the gas storage device located outside the door, and the user selects the grain inspection operation form on the access control host;

[0035] S4. The user installs the detector on the detection base connected to the gas storage device. The detector automatically starts when inserted into the detection base. The access control host detects the detector and successfully shakes hands with the detector. The access control host issues a gas detection control command, and the detector starts gas detection. The gas detection results are displayed on the access control host and uploaded to the granary management platform.

[0036] S5. When the gas detection result shows that it is safe, the unlock button on the access control host pops up. The user clicks the unlock button, the smart door unlocks and reports the switch status of the smart door to the access control host. The door control host prompts the user that the door has been unlocked and asks the user to proceed. The information of the user entering the warehouse is stored in the granary management platform.

[0037] S6. After entering the granary, the user performs grain inspection according to the grain inspection operation sheet within the limited space of the granary;

[0038] S7. After the user completes the grain inspection operation in the limited space of the granary, the face is detected in front of the smart door and compared with the face database for recognition. After the face ID is recognized, the smart door is locked, and the user registers the grain inspection operation result on the user terminal, and the grain inspection operation form on the access control host is closed.

[0039] More specific methods of grain inspection include Figure 2As shown in the figure, the entire working method is mainly divided into the granary management platform side, the access control host side, and the smart door, door lock, air pump, detection base, and gas detector side. Users use the app on the user terminal to register their personnel information. The registration information includes name, work number, department, and position. The granary management platform performs addition, update, and deletion operations based on the personnel information registration application of the user terminal. The user's personnel information is stored in the granary management platform, and the granary management platform also stores the personnel information in the access control host.

[0040] When a single grain inspection is required at a granary, the administrator sends a work order to the user terminal via the granary management platform. The work order includes information such as the work order number, operation type, granary location, inspector, date / time limit, and grain inspection work order status. After receiving the work order, the user applies for a grain inspection work order from the granary management platform through the user terminal and obtains approval. Once approved by the administrator, the grain inspection work order is sent to the user terminal and the access control host, including information such as the work order number, work order type, granary location, inspector, date / time limit, and grain inspection work order status. The access control host receives and stores the grain inspection work order, storing it by person / face, operation type, and time dimension, and supports searchability. If the grain inspection work order is not approved, the user needs to reapply for a grain inspection work order.

[0041] The user begins an on-site grain inspection based on the information on the grain inspection worksheet. Upon reaching the designated granary's intelligent door, a facial recognition device connected to the access control host detects the user's face and compares it with the granary management platform's facial database. The facial ID identified by the facial recognition is then retrieved from the access control host, first on the granary management platform, and then on the granary management platform. If a grain inspection worksheet is found, it is displayed on screen 1 of the access control host. The user selects it on screen 1, and the access control host simultaneously activates an air pump to collect gas from various detection points within the granary for 60 seconds, storing it in a gas storage device. Both the gas storage device and the air pump are located outside the granary. If the user remains on screen 1 for 90 seconds without any action, the access control host returns to the facial recognition step. If the user does not find a grain inspection worksheet, the access control host re-queries the worksheet information.

[0042] After selecting the grain inspection worksheet, a detector installation guide will appear on Interface 2 of the access control host. The user should install the detector on the detection base according to the installation guide. The detector can detect the gas concentration in the gas storage device. After the user installs the detector on the detection base, the detector will automatically start after installation. The access control host will begin to check whether the detector is installed in place. If the access control host detects the detector, it will then perform a handshake with the detector. The handshake here refers to the connection between the access control host and the detector. If the access control host fails to detect the detector for the first time after more than 120 seconds, the user should reinstall the detector and restart the 120-second timer. If the access control host detects the detector three times but still fails to shake hands with the detector, the access control host will prompt a device failure. Please repair it and return to the face detection step. Ensure that the access control host and the detector have successfully shaken hands before continuing with the following process.

[0043] After a successful handshake between the access control host and the detector, a gas detection control command is issued, and the access control host's screen 3 displays "Gas Safety Testing in Progress." After the detector completes the test, it transmits the results to the access control host, concluding the test. The access control host displays the gas detection values ​​on screen 4, with normal gas detection values ​​displayed in green and those exceeding normal values ​​in red. The access control host also transmits the gas detection results to the granary management platform.

[0044] If the gas detection result is safe, the unlock button will be displayed on the access control host interface 6, and the unlock button will pop up / highlight, prompting the user to unlock the door. The user clicks the unlock button, and the smart door unlocks. At the same time, the smart door detects the smart door switch status and transmits it to the access control host. The smart door unlocking service is completed. After the access control host receives the smart door opening, it will prompt the user that the smart door lock has been opened and ask to proceed. The information of the user entering the warehouse will be stored in the grain warehouse management platform. Specifically, the smart door will be displayed on the access control host interface 7. After 10 seconds, it will jump to interface 8. Interface 8 will display the grain inspection operation form interface, including information such as operation in progress, operation name, operation form number, and operator. The user carries the detector into the warehouse to complete the grain inspection operation. The real-time detection and real-time alarm of the gas concentration in the grain warehouse further ensure the safety of the user entering the warehouse.

[0045] After the user completes the grain inspection in the limited space of the granary, the face is detected by the face recognition device in front of the smart door and compared with the face library. After the face ID is recognized, the smart door is locked, the user registers the grain inspection result on the user terminal, and the grain inspection operation form on the access control host is closed.

[0046] If the gas detection result is unsafe, the access control panel will prompt the user to ventilate the warehouse and advise against entering. A button will appear asking the user to proceed. A specific message will be displayed on the access control panel's screen 5: "Gas concentration exceeds standard, do you want to proceed?" If the user chooses to proceed, the access control panel will display screen 6, proceeding with the aforementioned steps for checking grain entering the warehouse. If the user chooses not to proceed, the access control panel will return to the face recognition screen.
