Description

Technical Field

[0001] The present invention relates to a method for storing and managing file data, specifically a data association method based on recorder number matching. Background Art

[0002] A data recorder is a device used to record audio and video during the task execution of business personnel (such as public security, traffic police, urban management, and can also be applicable to security, fire protection, etc. that require video recording) to ensure the transparency and fairness of the law enforcement process. With the continuous improvement of society's requirements for the rule of law and fairness, the demand for data recorders is also increasing day by day.

[0003] After business personnel enter the working state, they turn on the data recorder to record the business processing process during work. The content stored in the data recorder is uniformly uploaded to the data acquisition station after the business personnel return to the work location for data storage and used for future query. Generally, the data is stored by date, personnel, and time.

[0004] Currently, business personnel are required to manually select data and upload the data within the specific law enforcement time on the same day (such as: 14:00 - 15:00 on November 12, 2024) to the data acquisition station for convenient future reference and retrospective review of the on-site law enforcement status.

[0005] To address the above data redundancy and non-intelligent file data storage process, a Chinese patent with the publication number CN117896480A currently discloses a method, system, and related device for recording and storing video data. It sends an event number from the business system to the data recorder, and then the business personnel log in to the account on the data recorder and input the event number. The data content recorded by the data recorder is the file data corresponding to this event number. Then, only by inserting the data recorder into the data acquisition station, during the process of the data acquisition station backing up the file data of the data recorder, the event number will be used as an identification point for associating the file data.

[0006] Therefore, when the data recorder uploads the file data to the business system and the business system checks the case, the file data can be quickly retrieved from the server through the event number, which is convenient for business personnel to access and archive.

[0007] The automatic association method of the above data recorder is currently implemented by software. When using it, business personnel must strictly follow the software usage steps, log in to the account, enter the event number, scan the QR code, and perform a series of mechanical operations. If the account is logged out in the middle, the file data cannot be recorded. Therefore, business personnel need to be strictly trained before the equipment is used, and one person needs to have one machine. Otherwise, operations such as scanning the code to log in in the middle will be difficult to operate in areas with poor network signal coverage such as basements, mountainous areas, and high-speed tunnels, resulting in limited use of data recorders.

[0008] At the same time, due to the limited existing police force and the high turnover of auxiliary police personnel, the training on the use of data recorders is more frequent, which increases the training burden. The use of data recorders is generally in emergency situations. During the police response process, the police need to deal with more complicated police affairs and conflict incidents. It is difficult for them to enter the event number and log in to the police account according to the software requirements after arriving at the location of the police situation, and then handle the police situation.

[0009] Therefore, how to simplify the recording of file data after the police officers go out on a call, filter the valid parts of the file data, and associate the filtered file data with the event number of the business system is a technical problem that needs to be solved urgently. Summary of the invention

[0010] The purpose of the present invention is to provide a data association method based on recorder number matching. Through this association method, when a business system issues a task, a task hardware number is formed in a variety of ways, and the task hardware number is bound to a business number. When the business personnel connect the law enforcement recorder to the data acquisition station, the collected hardware number and the task hardware number can be compared to quickly associate the law enforcement recorder with the business number. According to the task time under the business number, the file data within the time period is associated with the business number. Automatic and rapid matching can be achieved without excessive operation by the police officer.

[0011] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: a data association method based on recorder number matching comprises the following steps: S00, each law enforcement recorder has a unique hardware number, and the hardware numbers of multiple law enforcement recorders form a hardware group; S10. The business system can input the user number of the business personnel, and the business system can generate a business number, a task unit for executing the business, and a task time according to the task, and bind the user number to the business number; S20, the integrated backend of the data collection station accesses the business system to obtain the business number, user number, task time and task hardware number; the task hardware number is retrieved from the hardware group to obtain the hardware number of the task, and the task hardware number is also bound to the business number; S30. When business personnel use law enforcement recorders, file data will be generated, and the file data will have a generation time. S40, after the law enforcement recorder is connected to the data collection station, the integrated background of the data collection station reads the hardware number of the law enforcement recorder to obtain the external number and the unit to which the recorder belongs. When the hardware number is the same as the task hardware number, or the task unit and the task hardware number are the same as the unit to which the recorder belongs and the external number of the recorder, jump to step S50 S50, the integrated background obtains the file data of the law enforcement recorder, and associates the file data generated during the task time with the business number; S60, the business number is bound with the user number, hardware number, and file data to form valid data; S70, the data collection station stores the valid data locally for long-term backup, or transmits the valid data to a dedicated server for long-term backup, or sets a corresponding long-term storage strategy according to the specific associated business type; S80. When checking the business in the comprehensive background, access and check the corresponding valid data through the business number.

[0012] Compared with the prior art, the data association method based on recorder number matching using the above technical solution has the following beneficial effects: 1. When issuing tasks in the business system, a law enforcement recorder task hardware number participating in this task is selected from the existing law enforcement recorder hardware group. Therefore, in the subsequent process, when the law enforcement recorder with this hardware number is connected to the data collection station, the association operation can be quickly triggered to quickly match the file data within the task time period of the law enforcement recorder to the business number.

[0013] For example, when issuing tasks, the business system will arrange the following information: business number A12345, assign police officer Zhang San to perform anti-fraud work from 13:00 to 15:00 on January 1, 2025, and specify the use of law enforcement recorder B112; and transmit the above information to the integrated background of the data collection station. After the police officer returns from the task, when the law enforcement recorder B112 is plugged in, the data collection station will automatically associate the file data in the law enforcement recorder B112 from 13:00 to 15:00 on January 1, 2025 with the business number A12345.

[0014] 2. The above data association methods are all associated by software. Business personnel cannot add or delete the associated file data, which reduces human operation as much as possible and can better ensure the fairness of the data in the law enforcement recorder.

[0015] III. Since the task hardware number is generated when the business system issues a task, after the police officer returns from duty, he only needs to connect the law enforcement recorder to the data collection station to complete the subsequent association operations. All association operations are performed by the software system instead of manual operations by humans, changing the active operation steps to passive operation steps of the software. There is no need for police officers to make prior association preparations for subsequent data association before law enforcement. This greatly reduces the preparatory work for association. Police officers only need simple training to be informed of the usage method to complete the teaching of association operations without excessive training.

[0016] IV. Since all file data association operations are located at the data collection station end, the data recorder can be operated offline (without the need to connect to the network) during use. Therefore, in areas where signals cannot be covered, such as mountains, basements, and highway tunnels, file data can still be collected normally without affecting the operations of business personnel.

[0017] V. The business association method in this case is mainly applicable to law enforcement officers such as police and urban management. Among them, the data recorder can be a law enforcement recorder for recording videos, audios, and photos during law enforcement. It can also be applicable during the duty of security guards, armed police, forensic doctors, etc. for recording work content. It can also be applicable to video creation teams with multi-person and multi-camera shooting. The data recorder can be a terminal device with video recording functions such as a camera or a mobile phone.

[0018] Currently, there are three forms of issuing the task hardware number: Issuing form 1: The business system enters the hardware group and selects the corresponding hardware number from the hardware group as the task hardware number of the law enforcement recorder participating in this task, and sends the "business number + task hardware number" to the comprehensive background.

[0019] Issuing form 2: If it cannot be generated in the business system, the task hardware number is attached to the user number, that is, the law enforcement recorder is bound to the business personnel. After the comprehensive background receives the "business number + business personnel", the comprehensive background finds the law enforcement recorder number of this business personnel as the task hardware number.

[0020] Issuing form 3: After the business personnel return from handling cases, they fill in the "business number + task hardware number" in the agreed format, and select each content to form valid data for association.

[0021] When the task hardware number adopts issuing form 1: The hardware numbers in the hardware group are stored in the business system. When the business system issues a task, it retrieves the hardware number from the hardware group to form the task hardware number. When the comprehensive background accesses the business system, it directly obtains the task hardware number. This is the first implementation method of this case. See Figure 1, that is, the business system directly enters the hardware number (internal number or external number). When the business system issues a task, it issues and binds the corresponding hardware number (internal number or external number) of the law enforcement recorder to the business number. The comprehensive background of the law enforcement recorder accesses the business system and can directly obtain this task hardware number (internal number or external number), and can compare it with the inserted device. If the hardware number of the inserted device = the task hardware number (internal number); or the unit to which the recorder belongs + the external number of the recorder = the task unit + the task hardware number (external number), it means that the inserted law enforcement recorder has a task to be associated, and the comprehensive background automatically performs the association operation.

[0022] When the task hardware number adopts the distribution form 2: The hardware numbers (internal numbers) within the hardware group are stored in the comprehensive background of the data collection station. There is one or more matching hardware numbers for the user number within the hardware group. After the business system issues a task, the comprehensive background accesses the business system, and the business number retrieves one or more matching hardware numbers from the hardware group through the user number to form the task hardware number (internal number). This is the second implementation method of this case. See Figure 2 , that is, the business system cannot directly enter the hardware number. It can only enter the hardware number (internal number) in the comprehensive background and use the hardware number (internal number) as an attachment to the user number of the police officer. Therefore, when the business system issues a task, there is only the user number under the business number, but there is no corresponding hardware number (internal number or external number) of the law enforcement recorder. Only when the comprehensive background of the data collection station accesses the business system, while obtaining the business number, it reads the user number of the police officer participating in this time, and then obtains the hardware number (internal number) of the law enforcement recorder under the name of this police officer from the hardware group in the comprehensive background. Due to situations such as maintenance and charging of the law enforcement recorder, a police officer usually has one or more law enforcement recorders.

[0023] When the task hardware number adopts the distribution form 3: The task hardware number (external number) can be input by the operator in front of the data collection station or through the comprehensive background. The input task hardware number (external number) must be the hardware number (external number) stored in the hardware group. This is the third implementation method of this case. See Figure 3, when the task is being assigned, if an emergency occurs or the business platform does not support the input of specific personnel or task hardware numbers, and only the business number is generated without specifying or being unable to specify the specific personnel and hardware numbers (internal number or external number), after the business personnel (police officers) complete the task and return, the task hardware number can be bound to the business number according to the agreed format (such as police officer Zhang San, short number 8**53, going on a mission with a 4G law enforcement recorder (Changhe 15)), or fill in the hardware number on the surface of the law enforcement record form (external number, unique within the unit) as the task hardware number for this time, for subsequent association of business data; or after the business personnel connect the law enforcement recorder to the data collection station, the data collection station reads the hardware number (internal number) of the law enforcement recorder as the task hardware number for this mission and binds it to the business number.

[0024] Preferably, the data association method further includes step S01. S01: The hardware number is divided into an internal number or / and an external number. Each law enforcement recorder has a unique internal number, and each unit can customize the number of its internal recorders to form an external number, which is unique within the unit. The internal number or / and the external number constitute the hardware number of the law enforcement recorder, and the hardware numbers of multiple law enforcement recorders form a hardware group. When using the external number, generally use the abbreviation of the police station + custom short number such as Changhe 01, Changhe 02, etc., or the police station uses letters instead, such as A01, B002, etc. for simple coding. Therefore, there are many ways to name the external number, and it can be named according to actual needs.

[0025] Preferably, in step S01, the hardware number uses both the internal number and the external number at the same time. The external number consists of a prefix and a suffix, and the suffix contains 2 or 3 digits. The prefix is mainly used to distinguish the unit or stationed location of the police officer. The suffix can be reused (the suffix is arranged upward from 01, 02, 03, 04...). Just make a distinction with the prefix. Since in the police system, the number of personnel in a police station or a public security bureau is generally from a dozen to several hundred, so the suffix is selected as 2 - 3 digits. If the stationed location is used as the prefix, the suffix can be as short as 1 digit (such as: North 1, meaning the first recorder in the North Defense Area), which can quickly distinguish personnel within the same unit or stationed location, facilitating police officers to identify the law enforcement recorder corresponding to themselves. Too complex coding is not conducive to police officers to distinguish law enforcement recorders, and simple codes are easier to use than long codes when selecting on the subsequent data collection station; in actual use, the suffix can also be directly used without using the prefix. In addition to using pure numbers for the suffix, it can also be character + number, such as Changhe - patrol car 01; Changhe - organ 01; Changhe - auxiliary police 01; code the suffix according to functions.

[0026] Preferably, when the comprehensive background obtains the business number and the task hardware number, when the comprehensive background of the data collection station compares the task hardware number, it can be compared according to the internal number or the external number.

[0027] Preferably, when the integrated background displays the external number, it can display both the prefix and the suffix of the external number, or only display the suffix of the external number. Since within the same unit, the suffix of the external number is unique, business personnel within the same unit only need to remember the suffix of the external number of their own law enforcement recorders to distinguish the ownership of the law enforcement recorders. Or when the law enforcement recorders are shared, after the business personnel receive a task, they can pick up the law enforcement recorder with the corresponding suffix according to the task prompt. The suffix is generally a two-digit number such as 01, 02,... 99.

[0028] Preferably, the data acquisition station has a preset value, which is the unit number of the affiliated unit. The law enforcement recorder has a unit number. When the law enforcement recorder is connected to the data acquisition station, the data acquisition station reads the unit number of the law enforcement recorder and compares it with the preset value. Only when they are the same can the next step be continued. When they are different, the data acquisition station is refused to access the law enforcement recorder. This avoids the mixing of data acquisition stations between units in different jurisdictions (that is, to prevent the police officers of Changhe Police Station from going to Gaoxin Police Station to upload file data); when the unit number of the law enforcement recorder read by the data acquisition station is different from the preset value, access can be refused or a prompt can be popped up. The specific function can be configured according to the specific situation; among them, the unit number of the law enforcement recorder can be the prefix of the external number.

[0029] Preferably, the data association method further includes step S51. In S51, during the association process, the file data is divided into an associated sequence and an unassociated sequence. The associated file data is located in the associated sequence, and the unassociated file data is located in the unassociated sequence. Business personnel can only view and check the content of the file data in the associated sequence and the unassociated sequence. For example, if the system distributes tasks from 16:10 to 18:00 in the afternoon, and the actual time for the police officers to arrive at the scene for handling is from 16:30 to 21:00, the integrated background will only automatically associate the file data within the time period from 16:10 to 18:00. That is, the file data within 16:10 - 18:00 will be automatically displayed in the associated sequence, while the file data for the remaining other times will be displayed in the unassociated sequence. The file data in the two sequences can only be viewed and cannot be deleted or added. The association result does not allow manual intervention or minimizes manual intervention. If there is an error in the file data, business personnel can only submit a request to apply for content modification, transfer the file data from the unassociated sequence to the associated sequence, and an operation trace needs to be left for future verification.

[0032] Figure 3 It is a flowchart of the data association method based on recorder number matching in Embodiment 3. Detailed implementation manners

[0033] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0034] Embodiment 1: As Figure 1 shown, the data association method based on recorder number matching includes the following steps: S00. Each law enforcement recorder has a unique hardware number, which is divided into an internal number and an external number. Each law enforcement recorder has a unique internal number (the internal number is the unique hardware ID carried by the device when it leaves the factory), and each unit can customize the number of the recorders within it to form an external number, which is unique within the unit. The internal number and the external number constitute the hardware number of the law enforcement recorder, and the hardware numbers of multiple law enforcement recorders form a hardware group.

[0035] S01. Setting of the external number: The external number consists of a prefix and a suffix. The suffix is 2 or 3 digits, and the prefix uses the unit name or the stationed location. Taking Changhe Police Station as an example, the examples of the external number are: Changhe 01, Changhe 02..., and taking the stationed location as an example, the example of the external number is: North 1, which means the recorder No. 1 in the North Defense Area. It is only necessary to ensure that the suffixes are not repeated under the same prefix.

[0036] S02. Setting of the preset value of the data acquisition station: The preset value is associated with the prefix of the external number. If the law enforcement recorder and the data acquisition station belong to the same unit, the preset value is the same as the prefix, ensuring that the data acquisition station is only used by internal personnel. When the prefix of the accessed law enforcement recorder is different from the preset value of the data acquisition station, access is refused and a prompt is popped up.

[0037] S10. The business system can input the user number of the business personnel. The business system can generate a business number, the task unit and the task time for executing the business according to the task, and bind the user number to the business number.

[0038] S11. The business system pre-enters the hardware group. When generating a business number, the business system selects a hardware number from the hardware group and generates a task hardware number to bind to the business number.

[0039] S20. The comprehensive background of the data acquisition station accesses the business system to obtain the business number, user number, task time, task unit and task hardware number.

[0040] S30. When the operator uses the law enforcement recorder, file data will be generated, and the file data carries the generation time.

[0041] S40. After the law enforcement recorder is connected to the data acquisition station, the integrated background of the data acquisition station reads the hardware number of the law enforcement recorder to obtain the external number of the recorder. When the prefix of the external number is the same as the preset value of the data acquisition station, jump to step S41; if not, pop up a prompt "Denied access to external device" and deny access.

[0042] S41. When the obtained external number of the recorder is the same as the task hardware number, jump to step S50; S50. The integrated background obtains the file data of the law enforcement recorder and associates the file data generated within the task time under the business number.

[0043] S51. During the association process, the file data is divided into an associated sequence and an unassociated sequence. The associated file data is located within the associated sequence, and the unassociated file data is located within the unassociated sequence. The operator can only view and check the content of the file data within the associated sequence and the unassociated sequence.

[0044] S60. The business number is bound to the user number, hardware number, and file data to form valid data; S70. The data acquisition station stores the valid data locally for long-term backup, or transmits the valid data to a dedicated server for long-term backup, or can set corresponding long-term storage policies according to the specific associated business type.

[0045] S80. When the integrated background reviews the business, it accesses and reviews the corresponding valid data through the business number.

[0046] Embodiment 2: When applying the data association method in the present invention to the police system, since the business system within the police system cannot be modified by a third party, when the applicant dispatches tasks in the business system, according to the user number of the police officers participating in the duty, the task hardware code is generated at the data acquisition station for subsequent automatic association.

[0047] Such as Figure 2 The data association method based on recorder number matching shown includes the following steps: S00, S01, S02, and S1O are all the same as in Embodiment 1.

[0048] S11. The data acquisition station pre-enters the hardware codes of all law enforcement records of the unit into the hardware group and binds the user numbers of the corresponding police officers to the hardware numbers.

[0049] S20. The integrated background access service system of the data collection station obtains the service number, user number, task time, and task unit, and obtains the hardware number within the hardware group according to the user number to form the task hardware number.

[0050] S30, S40, S41, S50, S51, S60, S70, and S80 are the same as those in Embodiment 1.

[0051] Embodiment 3: When the service system issues a task and does not specify a specific service personnel and law enforcement recorder, the service personnel need to input the service number by themselves after going out on duty and using the hardware number of the law enforcement recorder as the task hardware number for this time.

[0052] Such as Figure 3 The data association method based on recorder number matching shown includes the following steps: S00, S01, and S02 are the same as those in Embodiment 1.

[0053] S10. The service system can input the user number of the service personnel, and the service system can generate a service number, the task unit and task time for performing the service according to the task.

[0054] S11. After receiving the service number, the task unit designates service personnel to perform the task.

[0055] S20. The integrated background access service system of the data collection station obtains the service number, task time, task unit, and task hardware number.

[0056] S30. When the law enforcement recorder is used by the service personnel, file data will be generated, and the file data has a generation time.

[0057] S40. After the law enforcement recorder is connected to the data collection station, the integrated background of the data collection station reads the hardware number of the law enforcement recorder, obtains the external number of the recorder. When the prefix of the external number is the same as the preset value of the data collection station, jump to step S41; if not, pop up a prompt "Denying external device access".

[0058] S41. The service personnel find the service number by selecting or manually inputting content and enter below the service number; S42. Select the hardware number of the law enforcement recorder read by the data collection station. When there are many connected law enforcement recorders, the number can be manually input to quickly select the correct hardware number; as the task hardware number, it is bound to the service number.

[0059] S50, S51, S60, S70, and S80 are the same as those in Embodiment 1.

[0060] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
