Description

Technical Field

[0001] The present invention relates to electronics, radio, communications and electrical engineering technologies, and in particular to the positioning and management of valuable assets and key behaviors of management personnel, and specifically is a personnel behavior and asset positioning management system and an implementation method. Background Art

[0002] The rapid development of Internet of Things technology has transformed the personnel and asset management in modern society from traditional paper-based management to electronic management. Traditional management methods are inefficient and often error-prone.

[0003] Chinese patent CN202110299679.9 discloses a method for personnel and asset positioning management, but this method still has defects. In this technical solution, low-power Bluetooth or UWB positioning signals are used to perform high-precision positioning of personnel tags and asset tags; in the behavior of asset entry and exit, the precise spatial location information of the asset use personnel tags and asset tags is used to confirm the legality of the behavior. Due to the strong correlation between the asset operator tag and the identity of the asset operator, once the tag is lost or illegally transferred to others for use, it is very easy for the asset to enter and exit the warehouse illegally; in addition, due to the requirements of the precise positioning system, it is necessary to accurately measure the implementation scenario and set up at least three positioning base stations and corresponding power supply lines; in addition, due to the public characteristics of the Bluetooth frequency band, the Bluetooth radio system is very easy to be interfered with and attacked, thereby reducing the security and reliability of the entire management system, which is specifically manifested in: a. The operator tag of this solution is strongly related to the operator's identity, and there is a lack of on-site operator identity verification. The tag is lost or illegally transferred, which poses a major management risk. In some dangerous places, such as grid connection operations, there are even major safety risks; b. The deployment of this solution requires the installation of at least three fixed positioning base stations and power supply lines after on-site spatial survey, which makes the project deployment complex, increases the deployment cost, and increases the difficulty of maintenance; c. The implementation effect of this solution is greatly affected by the actual environment. For example, if it is deployed in a complex electromagnetic field environment such as a power grid switchgear or substation, the positioning data will drift, which will greatly reduce the actual implementation effect or even make it impossible to implement normally. Summary of the invention

[0004] The purpose of the present invention is to provide a personnel behavior and asset location management system and implementation method to address the deficiencies of the prior art. This system has strong anti-interference ability, does not require engineering surveys, has fast on-site deployment, can verify the identity of operators in real time on-site, and complete the management and supervision of the entry and exit of valuable assets, the use of important items, and the operation of key equipment. This method is easy to operate, practical, and efficient.

[0005] The technical solution for achieving the purpose of the present invention is: A personnel behavior and asset positioning management system includes a freely movable personnel tag unit, a management unit connected to an operation object, a PoE switch and a background management unit. The personnel tag corresponds to the operator one by one and records the biometrics or password of the user, so that one person has one tag. The management unit obtains power through the PoE switch and communicates with the background management unit, and is connected to the management object by an electric locking mechanism. The background management unit arranges the behavior management objects and processes in a coordinated manner. The management unit adopts AOA ranging positioning and short-range high-speed communication technology with strong anti-interference ability and centimeter-level accuracy in ultra-wideband UWB communication to realize personnel behavior and asset positioning management.

[0006] The electric-controlled locking mechanism is a locking mechanism for key equipment such as asset locks and high-voltage transformers.

[0007] The personnel tag unit includes a first microcontroller unit and a battery management unit, an identity recognition unit, and a UWB communication unit connected to the first microcontroller unit. The battery management unit is connected to a battery pack. The identity recognition unit is used to obtain the identity information of the tag holder and identify the person through biometric recognition or a keyboard password. The battery pack is used to provide the power required for the tag to work. The battery management unit is used to charge the battery pack and manage the power supply of other units. The microcontroller unit is used to obtain the identification information of the identity recognition unit, and determine whether the identity of the holder bound to the tag is consistent, and transmit the result through the UWB communication unit, and also respond to the UWB AoA ranging data.

[0008] The management unit includes a second microcontroller unit and a UWB AoA communication unit, a PoE power management unit, a network communication unit and an electric locking unit connected to the second microcontroller unit. The network communication unit is connected to the PoE switch and communicates with the background management unit; the PoE power management unit is connected to the PoE switch and obtains working power from the PoE switch, and supplies power to other units at the same time; the second microcontroller unit obtains the personnel tag distance, angle and identity authentication information through the UWB AoA communication unit, and after the comparison is completed, the electric locking unit is controlled according to the comparison result; the electric locking unit is connected to an external operation object to lock or unlock the external structure.

[0009] A method for implementing a personnel behavior and asset location management system, using the above-mentioned personnel behavior and asset location management system, the method comprises the following steps: 1) The management unit is in a locked state, and the background management unit coordinates the behavior management and sends the number and identity information of the designated personnel who have completed the behavior operation to the management unit through the PoE switch; 2) The management unit starts UWB AoA positioning and ranging, obtains the straight-line distance and angle of the designated person's tag, and waits for the designated person carrying the person's tag to enter the effective distance range; 3) After the designated person enters the effective range with the personnel tag, the management unit notifies the personnel tag to identify the holder. The designated person confirms his identity through the identification feature of the tag. The tag sends the confirmation result to the management unit via UWB. The identification feature refers to the fingerprint biometric feature or keyboard password. 4) The management unit compares the tag ranging positioning information, the holder's identity authentication information with the data issued by the management unit, and reports the comparison results to the background management unit. If the comparison is the same, the electronic locking mechanism is unlocked and the on-site personnel can proceed to the next step. Otherwise, the unlocking is refused and the next step is not allowed.

[0010] This technical solution has the following advantages: a. There is an identity confirmation operation on site, which can effectively avoid the impact on behavior management caused by loss, false claim, illegal transfer, etc. of tags; b. No precise spatial positioning information is required, no additional positioning base stations and power supply lines are required. By using the AoA positioning and ranging characteristics of UWB, only the relative straight-line distance and angle between the management device and the personnel tag need to be obtained, which greatly optimizes the cost, complexity and maintenance difficulty of the solution implementation. c. Due to the strong anti-interference ability of UWB, this solution can be applied to scenarios with complex electromagnetic environments to further improve the reliability of behavior management.

[0011] This system has strong anti-interference capabilities, does not require engineering surveys, and has fast on-site deployment. It can verify the identity of operators in real time on site and complete the management and supervision of the entry and exit of valuable assets, the use of important items, and the operation of key equipment. This method is easy to operate, practical, and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The electric-controlled locking mechanism is a locking mechanism for asset locks and key high-voltage transformer switch equipment.

[0017] like Figure 2 As shown, the personnel tag unit includes a first microcontroller unit and a battery management unit, an identity recognition unit, and a UWB communication unit connected to the first microcontroller unit. The battery management unit is connected to a battery pack. The identity recognition unit is used to obtain the identity information of the tag holder and identify the person through biometric recognition or a keyboard password. The battery pack is used to provide the power required for the tag to work; the battery management unit is used to charge the battery pack and manage the power supply of other units; the microcontroller unit is used to obtain the identification information of the identity recognition unit, and determine whether the identity of the holder bound to the tag is consistent, and transmit the result through the UWB communication unit, and also respond to the UWB AoA ranging data.

[0018] like Figure 3 As shown, the management unit includes a second microcontroller unit and a UWB AoA communication unit, a PoE power management unit, a network communication unit and an electric locking unit connected to the second microcontroller unit. The network communication unit is connected to the PoE switch to communicate with the background management unit; the PoE power management unit is connected to the PoE switch and obtains working power from the PoE switch, and supplies power to other units at the same time; the second microcontroller unit obtains the personnel tag distance, angle and identity authentication information through the UWB AoA communication unit, and after the comparison is completed, the electric locking unit is controlled according to the comparison result; the electric locking unit is connected to an external operation object to lock or unlock the external structure.

[0019] A method for implementing a personnel behavior and asset location management system, using the above-mentioned personnel behavior and asset location management system, the method comprises the following steps: 1) The management unit is in a locked state, and the background management unit coordinates the behavior management and sends the number and identity information of the designated personnel who have completed the behavior operation to the management unit through the PoE switch; 2) The management unit starts UWB AoA positioning and ranging, obtains the straight-line distance and angle of the designated person's tag, and waits for the designated person carrying the person's tag to enter the effective distance range; 3) After the designated person enters the effective range with the personnel tag, the management unit notifies the personnel tag to identify the holder. The designated person confirms his identity through the identification feature of the tag. The tag sends the confirmation result to the management unit via UWB. The identification feature refers to the fingerprint biometric feature or keyboard password. 4) The management unit compares the tag ranging positioning information, the holder's identity authentication information with the data issued by the management unit, and reports the comparison results to the background management unit. If the comparison is the same, the electronic locking mechanism is unlocked and the on-site personnel can proceed to the next step. Otherwise, the unlocking is refused and the next step is not allowed.

[0020] In this example, specifically: a. Deployment phase: Enter personnel information, personnel tag information, and management unit information into the background management unit; The tag is bound to the holder one-to-one, and the identity information of the holder is stored in the tag; Multiple management units are aggregated to the background management unit through switches; No need to build a positioning base station; b. Operation phase: Assume that a valuable item W needs to be taken out of the warehouse. Operators A, B and C need to be present at the same time to perform the operation. Each operator is bound to his or her own corresponding personnel tag A, B and C. Each tag stores the identity information of the corresponding holder. The storage lock of the valuable item is managed by the management unit X. The process is as follows: ①X is in standby mode and is performing locking protection for W. The background management unit makes overall arrangements and sends the tag information of A, B, and C to X; ②After receiving the information from the three tags, X starts to send AoA ranging positioning data to tags A, B, and C, waiting for tags A, B, and C to enter the nearby space range of X; ③ A, B, and C carry the personnel tags A, B, and C bound to themselves and enter the near space range of X. After X detects that A, B, and C have all entered the near space range, it sends an identity authentication request to each tag through the UWB AoA communication unit; ④ Tags A, B, and C respectively prompt operators A, B, and C to authenticate their identities. A, B, and C complete the authentication operation through the identity recognition units on their respective bound tags A, B, and C. Then tags A, B, and C send the identity confirmation information to X through the UWB communication unit; ⑤X compares the tag information in the vicinity with the information sent by the background management unit, and decides the operation to be performed on the electric control locking unit according to the comparison result and the identity confirmation information returned by the tag. If the comparison result is the same and the identity confirmation information is correct, it is considered that the unlocking condition of the electric control locking unit is met and the unlocking operation is performed; otherwise, the electric control locking unit remains locked; ⑥ After X completes the unlocking operation, A, B, and C can perform the W outbound operation. After the outbound operation is completed, and A, B, and C leave the adjacent space range of X, X automatically completes the locking operation and enters the standby state; All the above process information is returned to the background management unit in real time through the network communication unit, and multiple behaviors or multiple actors queue up to perform the above steps multiple times.
