Description

Technical Field

[0001] This invention relates to the field of prison visitor management technology, and in particular to a digital closed-loop management system for the entire process of visitor management. Background Technology

[0002] As special supervisory facilities, prisons rely heavily on the management of visitors (including maintenance personnel, family visitors, and those transporting supplies) to ensure the safety and stability of the prison area. Currently, some prisons still rely on traditional manual registration and paper-based approval methods for managing visitors, which are cumbersome and inefficient. Manual registration is prone to errors and omissions in data entry, and paper-based approval documents are difficult to store, retrieve, and trace, making it difficult to meet the needs of modern supervision.

[0003] Existing digital management and control systems only cover certain aspects of the entry and exit of visitors, lacking closed-loop management of the entire process. For example, some systems only implement appointment registration but do not monitor the movement trajectory after entering the detention area in real time, nor do they establish a binding control between personnel and their carried tools. This makes it impossible to keep track of the visitor's activity status within the detention area in real time, and risks such as tool loss and unauthorized use are difficult to prevent. At the same time, the approval process of existing systems lacks flexibility and hierarchical management, and cannot set different approval permissions and processes according to differences in the reason for the visit and the department visited, resulting in low approval efficiency and security vulnerabilities.

[0004] Furthermore, the existing control system suffers from fragmented data storage and a lack of effective data linkage between different stages. This results in incomplete data sources for visitor appointment information, approval information, entry and exit records, and trajectory information, making subsequent tracing and auditing difficult. In the event of a security incident, it is challenging to quickly trace the activity trajectories and related information of relevant personnel, posing a significant challenge to the security management of the prison area.

[0005] Therefore, developing a digital management and control system for visitors that covers the entire process, integrates multiple modules, and establishes a closed-loop data system has become a key requirement for improving the security and efficiency of prison supervision. Summary of the Invention

[0053] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0054] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and the present invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0055] Example 1

[0056] This embodiment discloses a digital closed-loop management and control system for visitors throughout the entire process, which is used for the full-process management and control of visitors to prisons. The system is deployed on the server of the prison area management and control center and communicates with various terminal devices and monitoring devices through the network.

[0057] 1. System Module Settings

[0058] Appointment Approval Module: Deployed on platform terminals, handheld APP terminals, and self-service registration machine terminals, the appointment information collection unit supports collecting the visitor's ID number, name, contact number, reason for visit (such as visiting relatives, repair, transporting materials, etc.), visiting department (such as the visitor management department, prison administration department, etc.), validity period (start time and end time), activity trajectory (preset allowed activity areas within the prison area), information on carried tools (name, quantity, unit, etc.), and supporting materials (safety commitment letter, front and back of ID card, construction plan, etc.). The multi-level approval unit has preset approval rules. For example, the appointment of visitors to enter the prison requires approval from both the prison administration department and the office. The approver receives the approval request through the platform terminal, reviews the appointment information and supporting materials, selects "approval" or "rejection" and fills in the comments. The approval result is synchronized to the applicant's terminal in real time.

[0059] Identity verification module: ID card readers, facial recognition devices, and access control devices are deployed at key nodes such as the prison area entrance, the armed police pedestrian passage, the police pedestrian passage, and the work area entrance. The multi-mode verification unit supports a combination of ID card swiping verification and facial recognition verification. The node verification unit is set with verification logic. Visitors must first pass ID card swiping or facial recognition verification at the entrance. After successful verification, they enter the armed police passage, where they undergo identity and tool verification again. After passing the verification, they enter the police passage. Only after completing the final verification can they enter the designated work area. If any node verification fails, entry will be denied, and a platform warning will be triggered.

[0060] Tracking Module: Facial recognition devices, access control devices, and positioning beacons are deployed in passageways, work areas, and public areas within the prison area. The location acquisition unit uses these devices to collect the location information of visitors in real time. For example, facial recognition devices identify visitors' faces and record their locations, while access control devices record the time visitors enter and exit areas. The trajectory generation unit organizes the location information into an activity trajectory map in chronological order, marking the dwell time at each location, the areas traversed, and the corresponding verification records. The trajectory data is synchronized to the platform terminal in real time, allowing administrators to view the activity status of visitors in real time through the platform terminal.

[0061] Tool Management Module: The tool registration unit has a pre-set tool library containing commonly used tools such as electric hammers, screwdrivers, computers, and ladders. When making an appointment or registering, visitors can select tools from the tool library. If a corresponding tool is not found, the visitor can add a tool name, unit, quantity, and upload a picture of the tool. The tool verification unit has accompanying officers check the consistency between the tools and the registered information at the entry point. After confirming that there are no errors, the officers sign to confirm. The cancellation unit has the tools checked again at the departure point. After comparing the information with the registered information, the cancellation is completed and a cancellation record is generated. If there are any cases where tools are not taken out or new tools are added, the reasons must be explained and approved before leaving the prison.

[0062] The responsibility binding module: The accompanying police officer matching unit provides an accompanying police officer search function during the registration process. It allows users to search for and bind accompanying police officers by employee number or name, establishing a one-to-one relationship between visitors and accompanying police officers. The responsibility recording unit records the accompanying police officer's employee number, department, contact information, and scope of responsibilities, including supervising visitors to follow a preset trajectory, verifying their tools, and being responsible for monitoring visitors' behavior during their stay in custody. The accompanying police officer information is synchronized to each verification node for easy confirmation by verification personnel.

[0063] Data storage module: An encrypted database is used to store all data generated by each module, including appointment data (ID number, name, reason for visit, etc.), approval data (approver, approval opinion, approval time, etc.), verification data (verification node, verification method, verification result, etc.), trajectory data (location information, stay time, areas passed through, etc.), tool data (tool name, quantity, verification record, etc.), and responsibility-related data (accompanying police officer information, scope of responsibilities, etc.). The data storage period is set according to regulatory requirements, and traceability queries are supported by keywords such as personnel name, ID number, and time.

[0064] Terminal interaction module: The platform terminal is deployed in the prison area control center, allowing management personnel to perform system configuration (such as setting approval rules, configuring verification nodes, etc.), approval operations, data query and monitoring; the self-service registration machine terminal is deployed at the prison area entrance, supporting visitors to swipe their ID cards to read information on-site, manually supplement and improve appointment information, and bind accompanying police officers; the handheld APP terminal is installed on the police officers' mobile phones, supporting visitor appointment, registration, data collection and approval operations in mobile scenarios. For example, police officers can collect visitor information and initiate approval on-site through the APP.

[0065] 2. Working principle

[0066] Visitors submit appointment requests via self-service registration terminals, handheld APP terminals, or platform terminals. The appointment approval module collects appointment information and initiates multi-level approvals. After approval, visitors undergo initial identity verification at the prison entrance through the identity verification module, completing registration and being bound to an accompanying officer. They then pass through the armed police channel and the officer channel for identity and tool verification before entering the designated work area. During their stay, the trajectory tracking module collects the visitor's location information in real time, generates an activity trajectory, and synchronizes it to the platform terminal for real-time monitoring by management personnel. Accompanying officers supervise the visitor's behavior according to their responsibilities and verify tool usage. After completing their visit, visitors undergo secondary verification through the identity verification module at the departure point. The tool management module completes tool cancellation, and the responsibility binding module confirms the accompanying officer's opinion. After all processes are completed, the data storage module encrypts and stores all data, supporting subsequent traceability and querying, achieving closed-loop management of visitors throughout their entire lifecycle.

[0067] Example 2

[0068] like Figure 1 and Figure 2 As shown, this embodiment discloses a method for full-process digital closed-loop management and control of external personnel, which is implemented based on the system described in Embodiment 1. The specific steps are as follows:

[0069] Step 1: Appointment Application

[0070] Visitors can select a terminal (self-service registration machine, handheld APP, or platform terminal) to submit an appointment request based on their visit needs. They should enter their identity information (ID number, name, contact number, ethnicity, etc.), reason for visit (visiting relatives, maintenance, transporting supplies, etc.), visiting department (visit management department, prison administration department, etc.), validity period (start and end time, 1 day, 2 days, 3 days, 5 days, etc.), activity trajectory (select a preset activity area within the prison area, such as the first-floor work area), and information on tools carried (select tools from the tool library or add new tools, name, quantity, unit, and upload pictures). They should also upload supporting materials (safety commitment letter, front and back of ID card, driver's license, vehicle registration certificate, etc., selected according to the type of visit).

[0071] Step 2, Multi-level Approval

[0072] The system, based on preset approval rules (such as setting approval levels according to the reason for the visit and the department visited), forwards appointment requests to the first-level approval node (e.g., the prison administration department). Approving personnel view the appointment information and supporting materials through the platform terminal. If the information is complete and meets regulatory requirements, they click "Approve" and fill in their approval comments, forwarding the request to the second-level approval node (e.g., the office). Second-level approvers also view the information and provide their approval comments. The final approval result is synchronized to the visitor's terminal in real time. If approved, an appointment voucher is generated; if rejected, the reason for rejection is explained. If the appointment process is enabled, visitors must register within the validity period.

[0073] Step 3: Identity Registration

[0074] After the appointment is approved, visitors bring their ID cards to the self-service registration terminal at the entrance of the prison area, place their ID cards in the sensing area to read their identity information, and the system automatically associates the appointment information. Visitors then supplement and improve their information such as body temperature, activity trajectory, and protective measures (e.g., whether they are wearing masks). They search for and bind their accompanying police officers through the terminal. After the accompanying police officers verify and confirm their identity through their employee ID or card, the system generates a registration certificate and issues it to each verification node.

[0075] Step 4: Verification upon entry into prison

[0076] Visitors with registration credentials first enter the armed police channel, placing their ID cards on the ID card reader or undergoing facial verification. The identity verification module compares the identity information with the registration information. After confirming that the information matches, the accompanying police officer verifies that the tools carried match the registration information. Once confirmed, the officer signs for confirmation, and the armed police channel door opens automatically. After entering the police channel, visitors undergo facial verification or ID card verification again. The system verifies the information of the accompanying police officer and the approval result. Once the verification is successful, the police channel door opens, and visitors enter the designated work area.

[0077] Step 5: Track Monitoring

[0078] During the period of time that visitors are in custody, the trajectory tracking module collects their location information in real time through facial recognition devices, access control devices, and positioning beacons deployed within the prison area. It generates an activity trajectory map in chronological order, marking the time spent at each location, the areas traversed, and the corresponding verification records. If a visitor exceeds the preset activity trajectory range, the system triggers an alert and pushes it to the terminals of the accompanying police officers and the management personnel in the control center. The management personnel then promptly contact the accompanying police officers to verify the situation.

[0079] Step 6: Tool Management

[0080] Upon entering the prison, the accompanying officers have verified that the tools match the registered information. During their stay in prison, visitors must register the time and purpose of using the tools in the tool usage logbook. If a new tool is needed or a tool is damaged, a tool change application must be initiated through the accompanying officer, and the tool registration information will be updated after approval. The accompanying officers will regularly check the condition of the tools to ensure that they are used for their registered purposes.

[0081] Step 7: Verification of release from prison

[0082] After completing their visit, visitors undergo a second identity verification (facial recognition or ID card verification) at the departure point. The tool management module checks the tools taken out and verifies them against the registered information to complete the verification. The accompanying officer confirms that the visitor has no violations and that all tools have been taken out before signing for confirmation. After both the identity verification module and the tool verification are completed, the officer's passage door and the armed police passage door are opened in sequence, and the visitor leaves the prison. The system updates the visitor's status to "departed from prison".

[0083] Step 8: Data Archiving

[0084] The system encrypts and stores all process data (appointment data, approval data, registration data, verification data, trajectory data, tool data, and verification data) in the data storage module. The data is retained in accordance with regulatory requirements. Managers can use the platform terminal to query and trace relevant data by keywords such as personnel name, ID number, and time for auditing or security incident investigation.

[0085] Example 3

[0086] This embodiment, based on Embodiment 1, refines the appointment approval module. In addition to collecting basic information, the appointment information collection unit supports collecting differentiated information based on visit type (short-term, long-term). Short-term visits (e.g., 1-3 days) do not require a criminal record check, while long-term visits (e.g., exceeding 3 days) require one. If the visit is for repairs and requires construction, a construction plan must also be uploaded. The multi-level approval unit supports setting approval timeout reminders. If the approver fails to complete the approval within a preset time (e.g., 24 hours), the system automatically pushes a reminder message to the approver's terminal. The approval process supports a withdrawal function; the applicant can withdraw the appointment request and resubmit it after modifying the information before approval is completed. Approval results are notified via SMS; after approval or rejection, the system automatically sends an SMS notification to the contact number provided by the visitor, informing them of the subsequent procedures.

[0087] Example 4

[0088] This embodiment, based on Embodiment 1, refines the identity verification module. The multi-mode verification unit supports not only ID card swiping verification and facial recognition, but also password verification. Visitors can set a verification password during registration and enter it at subsequent verification nodes to complete the verification. For visitors without ID cards, manual input of their ID number followed by facial recognition is supported; the verification is only successful if the facial recognition and ID number match. The node verification unit displays verification records at each node, allowing administrators to view the verification time, method, and result for each node via the terminal. If verification fails, the system displays the reason for the failure (e.g., facial recognition failure, inconsistent ID information), facilitating troubleshooting for both visitors and verification personnel.

[0089] Example 5

[0090] This embodiment refines the trajectory tracking module based on embodiment 1. The location acquisition unit adopts a combination of timed acquisition and triggered acquisition. The timed acquisition interval is set according to regulatory requirements (e.g., 5 minutes / time). Acquisition is triggered when an outsider enters a new area to ensure the real-time nature of the trajectory data. The trajectory generation unit supports trajectory playback function, allowing managers to select any time period to replay the activity trajectory of outsiders and intuitively view their movement routes and stay in the monitoring area. The trajectory data supports anomaly marking. When an outsider stays in a certain area for a longer period of time than a preset threshold (e.g., 1 hour) or enters an unauthorized area, the system automatically marks the abnormal trajectory, facilitating key investigations by managers.

[0091] Example 6

[0092] This embodiment refines the tool management module based on embodiment 1. The tool registration unit supports tool classification management, dividing tools into categories such as maintenance tools, material tools, and personal tools. Visitors can filter tools by category, improving registration efficiency. The tool verification unit supports tool image comparison. When entering the prison, accompanying officers can view the registered tool images on the terminal and compare them with the actual tools for confirmation. The cancellation unit supports partial cancellation function. If a visitor takes some tools out, the taken-out portion can be cancelled first. The remaining portion needs to be explained and approved before it can be retained or taken out later. The system records the partial cancellation status and approval opinions.

[0093] Example 7

[0094] Based on Example 1, this embodiment refines the settings of the rights and responsibilities binding module. The accompanying police officer matching unit supports one-to-many binding, allowing one accompanying police officer to bind multiple external personnel (no more than 10 people) at the same time. The system displays a list of bound external personnel, facilitating unified management by the accompanying police officers. The rights and responsibilities recording unit supports the rights and responsibilities change function. If an accompanying police officer is unable to continue performing supervisory duties due to work adjustments, they can initiate a rights and responsibilities change application through the platform terminal, select a new accompanying police officer, and complete the change after approval. The change record is synchronized to the entire process data.

[0095] Example 8

[0096] Based on Example 1, this embodiment refines the terminal interaction module. The platform terminal supports data statistical analysis functions, which can statistically analyze data such as the number of visitors, approval rate, and average stay time by dimensions such as time, visit type, and visiting department, generate statistical reports, and support export. The self-service registration machine terminal supports voice prompts, guiding visitors to complete operations such as information entry, ID card verification, and binding of accompanying police officers during operation, thereby improving operational efficiency. The handheld APP terminal supports offline operation, which can temporarily store the collected visitor information in the absence of network environment, and automatically synchronize it to the system after the network is restored to ensure that the data is not lost.

[0097] Example 9

[0098] This embodiment, based on Embodiment 2, refines the multi-level approval process. Appointment approval includes preliminary review and secondary review. The preliminary review is conducted by the head of the visiting department, verifying the rationality of the reason for the visit and the accuracy of the visiting department. The secondary review is conducted by the prison administration department, verifying the completeness of the appointment information and the compliance of supporting materials. Registration approval includes verification review and final review. Verification review is conducted by entry verification personnel, verifying the authenticity of the identity information and the binding status of accompanying officers. The final review is conducted by management personnel in the control center, verifying the consistency of information throughout the process. Upon successful review, entry permission is generated. During the approval process, if any level of approval is rejected, the system returns the information to the appointment applicant, who can then modify the information and re-initiate the approval process.

[0099] Example 10

[0100] This embodiment refines the entry verification steps based on Embodiment 2. The verification at the Armed Police channel includes identity verification, tool verification, and temperature checks. Identity verification is completed by swiping an ID card or facial recognition. Tool verification is conducted by Armed Police officers who check the tools against the registration information. Temperature checks are completed using the temperature measurement function of the self-service registration terminal; a temperature between 36.2-37.2℃ is considered normal. The verification at the Officer channel includes secondary identity verification, trajectory confirmation, and authority / responsibility confirmation. Secondary identity verification uses facial recognition to ensure consistency with the Armed Police channel verification. Trajectory confirmation involves the accompanying officer confirming the visitor's preset activity trajectory. Authority / responsibility confirmation involves the officer confirming the accompanying officer's scope of authority / responsibility. After all verification items are passed, the Officer channel door opens automatically.

[0101] Example 11

[0102] This embodiment refines the trajectory monitoring steps based on embodiment 2. The trajectory monitoring utilizes the collaborative work of facial recognition devices, access control devices, and positioning devices deployed within the prison area. Facial recognition devices identify the faces of visitors and record their locations, access control devices record the time visitors enter and exit the area, and positioning devices provide real-time location coordinates. The system integrates this data to generate a continuous activity trajectory, and the trajectory data is stored as an unalterable encrypted file to ensure data authenticity. Warning information is pushed to the terminals of accompanying officers and management personnel in the control center. Management personnel can view the current location of visitors and take appropriate action through real-time monitoring.

[0103] Example 12

[0104] This embodiment refines the exit verification process based on embodiment 2. Secondary identity verification uses a combination of facial recognition and ID card verification to ensure the exiting person matches the entering person. Tool removal verification is jointly checked by the accompanying officer and the exit verification personnel, confirming the consistency of tool name, quantity, and registration information. Both parties sign to confirm after verification. The accompanying officer confirms that the visitor has not violated any rules during their stay in prison, has followed the preset trajectory, and that tool use is compliant. After all verification items are completed, the system automatically updates the visitor's status to "exited," generates an exit record, and synchronizes it to the data storage module, completing the entire closed-loop process.

[0105] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
