Description

Technical Field

[0001] This invention relates to the field of special operation management technology, specifically to a special operation process management alarm method and system based on UWB. Background Technology

[0002] According to the definition in the national standard GB 30871-2022, "Safety Specifications for Special Operations in Hazardous Chemical Enterprises," special operations refer to activities that may involve hot work, entry into confined spaces, blind flange installation / removal, work at heights, hoisting, temporary power supply, excavation, and circuit breaking during the production and operation of hazardous chemical enterprises, which may cause harm or damage to the operator, others, and surrounding buildings / structures. The specifications stipulate that relevant supervisors, work supervisors, operators, and permit approvers must complete their supervision, work, and approval duties on-site during the operation. Simultaneously, personnel not involved in the operation are prohibited from being present in the work area to ensure thorough review and a standardized and controllable work process. The Ministry of Emergency Management requires hazardous chemical enterprises to establish special operation permit and process management systems with alarm functions to track the location of relevant personnel, ensure personnel are present as required, and reduce operational risks.

[0003] In existing technologies, most special operation systems use Bluetooth, GPS, and other technologies to determine whether personnel are in place. However, GPS positioning fails when the work area is indoors, and Bluetooth positioning accuracy is insufficient, exceeding 3 meters. To address personnel presence management during operations through location calculation, patent application CN118036895A proposes a special operation management system and method for chemical enterprises. This method uses GIS maps and personnel positioning technology to monitor the entire special operation process in real time, providing timely warnings of unsafe work behaviors and taking prompt countermeasures to control operational safety risks, thus overcoming the shortcomings of traditional manual control in managing unsafe work behaviors. While this solution discloses determining personnel presence within the work area through real-time positioning, it does not elaborate on the specific positioning techniques used or the accuracy of the positioning. Summary of the Invention

[0004] The purpose of this invention is to provide a special operation process management alarm method and system based on UWB. By associating special operation permit applications, dynamic electronic fences and operators, and based on UWB positioning technology, it improves the accuracy of personnel tracking and positioning in special operation permit and process management, and realizes full-process control of special operation processes.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] Firstly, a special job process management alarm method based on UWB is proposed, including:

[0007] Based on the control area map model, dynamic electronic fences corresponding to each work process are set in the control area map model according to several work processes of special work permit application.

[0008] Based on the application for special work permits, a number of operators are bound together with each operator and the corresponding work process through a unique identifier;

[0009] The system receives work order approval information and obtains the first real-time location of the worker corresponding to the work order based on the UWB real-time positioning system. The UWB real-time positioning system includes several positioning beacons and several positioning terminals for wearing positioning devices, which are distributed and installed within the controlled area.

[0010] The system invokes the work process and corresponding dynamic electronic fence bound to the operator, and determines whether the operator has triggered an alarm rule based on the first real-time location; wherein the dynamic electronic fence is in the open state, and the alarm rule includes multiple violations preset for the work process, the operator, and the dynamic electronic fence;

[0011] When the operator triggers an alarm rule, the alarm information is pushed to the management center and mapped to the operator, so that the management center can remind the operator to stop the violation or the operator can stop the violation on their own. The alarm will be automatically cleared and an alarm record will be generated. The alarm record includes the operator's information, the alarm rule triggered by the operator, and the alarm clearing status.

[0012] Furthermore, it also includes:

[0013] Based on the UWB real-time positioning system, the second real-time location of several workers applying for special work permits is obtained in real time;

[0014] Based on the second real-time location and the dynamic electronic fence corresponding to each work process, determine whether each worker is in any of the dynamic electronic fences that are in an open state, and the corresponding work process within the dynamic electronic fence.

[0015] For operators who are not within any of the aforementioned dynamic electronic fences, and for operators who are not part of any of the work processes as determined by all operators bound to each work process, an alarm message is pushed to the management center and mapped to the operator, so that the management center can remind the operator to enter the dynamic electronic fence of their corresponding work process and then automatically clear the alarm.

[0016] Furthermore, it also includes:

[0017] Based on the UWB real-time positioning system, the third location information of all personnel in the controlled area is obtained in real time;

[0018] Based on the third location information, determine the information of all personnel located within the dynamic electronic fence corresponding to each work process;

[0019] Based on the unique identifier of the personnel information, it is determined whether there are non-operating personnel when the dynamic electronic fence is open. If there are non-operating personnel, an alarm message is pushed to the management center so that the management center can remind the personnel to leave the dynamic electronic fence.

[0020] Furthermore, it also includes:

[0021] Based on the time of the push alarm information, the fourth location information of the person is obtained through the UWB real-time positioning system after a preset time interval;

[0022] Determine whether the fourth location information is not within the dynamic electronic fence corresponding to any work process; if the fourth location information is not within the dynamic electronic fence corresponding to any work process, determine that the person has left the dynamic electronic fence; otherwise, push an upgraded alarm message to the management center so that the management center can send an alarm command to the person.

[0023] Furthermore, it also includes:

[0024] The first time when the staff member enters the dynamic electronic fence corresponding to the workflow and the second time when the staff member leaves the dynamic electronic fence corresponding to the workflow are obtained;

[0025] Based on whether a work process completion application corresponding to the operator is received within the time interval between the second time and the first time, it is determined whether the operator's act of leaving the dynamic electronic fence is in violation of regulations.

[0026] If no work completion application is received from the operator within the specified time interval, the operator's act of leaving the dynamic electronic fence is considered a violation, and an alarm message will be sent.

[0027] Furthermore, the ray method is used to determine whether each worker is within any of the aforementioned dynamic electronic fences.

[0028] Secondly, a special operation process management alarm system based on UWB is proposed, including:

[0029] The fence setting module is used to set up dynamic electronic fences corresponding to each work process in the controlled area map model based on the controlled area map model and according to the several work processes of the special work permit application.

[0030] The binding module is used to bind each operator and their corresponding work process based on a unique identifier of the operator, according to a special work permit application.

[0031] The receiving and acquiring module is used to receive work ticket approval information and acquire the first real-time location of the worker corresponding to the work ticket based on the UWB real-time positioning system; wherein, the UWB real-time positioning system includes several positioning beacons and several positioning terminals for wearing positioning distributedly installed within the controlled area;

[0032] The judgment module is invoked to invoke the work process bound to the operator and the corresponding dynamic electronic fence, and to determine whether the operator has triggered the alarm rules based on the first real-time location; wherein, the dynamic electronic fence is in the open state, and the alarm rules include multiple violations preset for the work process, the operator and the dynamic electronic fence;

[0033] The alarm push module is used to push alarm information to the management center and map it to the operator when the operator triggers the alarm rule. This allows the management center to remind the operator to stop the violation or the operator to stop the violation on their own. The alarm is then automatically cleared and an alarm record is generated. The alarm record includes operator information, the alarm rule triggered by the operator, and the alarm clearing status.

[0034] Furthermore, it also includes:

[0035] The location acquisition module is used to acquire the second real-time location of several workers applying for special work permits based on the UWB real-time positioning system.

[0036] The first judgment module is used to determine, based on the second real-time location and the dynamic electronic fence corresponding to each work process, whether each worker is in any of the dynamic electronic fences that are in an open state, and the work process corresponding to the dynamic electronic fence in which they are located.

[0037] The push module is used to push alarm information to the management center and map it to the operators who are not within any of the dynamic electronic fences and who are not part of the work process as determined by all operators bound to each work process. This allows the management center to remind the operators to automatically deactivate the alarm after they enter the dynamic electronic fence corresponding to their work process.

[0038] Thirdly, an electronic device is proposed, comprising at least one processor coupled to a memory storing a computer program configured to be executed by the processor to perform the aforementioned UWB-based special job process management alarm method.

[0039] Fourthly, a computer-readable storage medium is proposed, on which a computer program is stored, which, when executed by a computer, implements the above-mentioned UWB-based special job process management alarm method.

[0040] As can be seen from the above technical solutions, the technical solutions of the present invention have achieved the following beneficial effects:

[0041] This invention discloses a UWB-based alarm method and system for special operation process management. The method includes: setting dynamic electronic fences corresponding to each operation process in a control area map model based on several operation processes from a special operation permit application; binding each operator and their corresponding operation process to several operators from the special operation permit application through their unique identifiers; receiving operation ticket approval information and obtaining the first real-time location of the operator corresponding to the operation ticket using a UWB real-time positioning system; calling the operation process bound to the operator and the corresponding dynamic electronic fence, determining whether the operator has triggered an alarm rule based on the first real-time location, and pushing alarm information to the management center and mapping it to the operator when the operator triggers the alarm rule. This invention effectively manages the entire special operation process and improves the accuracy of personnel tracking and positioning in special operation process management.

[0042] This invention designs a special operation process management scheme based on a UWB real-time positioning system. Through the technical concept of special operation permits, electronic fences, and personnel binding, it effectively manages the automatic alarm and de-alarm functions for unauthorized entry or exit during special operation processes. By using a UWB real-time positioning system to generate and de-alarm for unauthorized departure or entry during special operations, this invention ensures that the real-time position accuracy of personnel can be controlled within 3 meters, meeting the relevant policy requirements for special operation personnel positioning and conforming to the actual operating conditions of special industries such as chemical plants. Compared with existing technologies, this invention can more accurately control special operation processes, ensure the implementation of safety production responsibilities by relevant personnel, and reduce operational risks and the probability of accidents.

Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art.

Similarly, unless the context clearly indicates otherwise, the singular forms of "an," "a," or "the," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one.

[0054] Current special operations systems primarily employ technologies such as Bluetooth and GPS for personnel location tracking. However, these methods suffer from insufficient positioning accuracy, leading to inaccuracies in personnel location during special operations and posing operational risks. Therefore, this invention aims to propose a special operations process management and alarm method and system based on UWB. This method associates electronic fences and personnel with the workflow of the special operations, and then uses a UWB real-time positioning system to determine the accurate location of personnel in real time, thereby improving the positioning accuracy of the special operations process and reducing operational risks.

[0055] The following detailed description, in conjunction with the specific embodiments shown in the accompanying drawings, further illustrates the UWB-based special operation process management alarm method and system disclosed in this invention.

[0056] Combination Figure 1 As shown, this invention discloses a special operation process management alarm method based on UWB, which includes the following steps:

[0057] Step S102: Based on the control area map model, set up dynamic electronic fences corresponding to each work process in the control area map model according to the several work processes of the special work permit application.

[0058] Step S104: Based on the special work permit application, bind each operator and the corresponding work process through the operator's unique identifier;

[0059] The above steps S102 and S104 include three steps in their specific implementation: constructing a special work permit application, binding the work process with the electronic fence area, and binding the work personnel with the work process.

[0060] Specifically, special operation permit applications are submitted to the work ticket management center using the special operation software system. The special operation software system supports the construction of work permit processes based on the actual enterprise operation specifications and processes, using low-code process engine tools. When building the special operation software system, it supports the customization of different operation stages, approval requirements, and approval content, and can also customize work ticket templates according to the actual work ticket format requirements of the enterprise.

[0061] After completing the process setup for special operation applications, the operation process is bound to the electronic fence. Specifically, a control area map model, such as a 3D or 2D model, is introduced into the user-facing page provided by the software to draw the electronic fences for the operation areas of different operation processes. The drawn electronic fence is in a dynamic start state and can automatically take effect or deactivate according to control requirements such as operation time and process status.

[0062] Subsequently, the work process is linked to the personnel involved in the work; in the process of submitting a special work permit application, internal and external personnel are introduced to build a work team, and then the work process is linked to the work personnel through a unique personnel identifier.

[0063] Step S106: Receive work ticket approval information and obtain the first real-time location of the worker corresponding to the work ticket based on the UWB real-time positioning system; wherein, the UWB real-time positioning system includes several positioning beacons and several positioning terminals for wearing positioning devices, which are distributed and installed within the controlled area.

[0064] When the UWB real-time positioning system is working, the positioning terminal communicates with the positioning beacon. The positioning terminal uses Time-of-Flight (TOF) or Time Difference of Arrival (TDOA) ranging methods to calculate the communication distance, and the positioning engine uses a ternary method to solve the coordinates, thereby determining the real-time position of the target. Compared with technologies such as Bluetooth and GPS, the UWB positioning method used in this invention has higher positioning accuracy. First, UWB positioning has extremely high time resolution, with a time resolution of 0.67ns at a pulse width of 2ns and a theoretical ranging accuracy of 20cm. Second, UWB positioning has strong wide-spectrum anti-interference capability; the 500MHz bandwidth gives the signal Shannon tolerance, making it identifiable in noise. In addition, UWB positioning has strong penetration; the 6.5GHz carrier frequency can penetrate non-metallic obstacles, such as concrete walls, with attenuation of only 15dB / m. Positioning tests were conducted in industrial environments using both Bluetooth and UWB positioning technologies. The measured accuracy of Bluetooth technology was 5–8m, while the measured accuracy of UWB positioning was 0.1–0.3m.

[0065] Furthermore, the existing publicly available UWB positioning software system is technically mature and can effectively bind the information of positioning terminals and special operation personnel. First, internal personnel information can be obtained by importing, entering, or connecting with enterprise ERP / HR systems. Second, for personnel outside the factory area, personnel information can be registered through a special operation app. Then, by establishing a positioning terminal management function in the UWB positioning software system, the positioning terminal can be bound to the operation personnel.

[0066] Step S108: Invoke the work process and corresponding dynamic electronic fence bound to the operator, and determine whether the operator has triggered an alarm rule based on the first real-time location; wherein, the dynamic electronic fence is in the open state, and the alarm rule includes multiple violations preset for the work process, the operator, and the dynamic electronic fence, such as the operator not entering the dynamic electronic fence of the corresponding work process, the operator not entering the special work area, the operator not entering the dynamic electronic fence of the corresponding work process within the specified time, the operator entering the dynamic electronic fence of the restricted work process, etc.; for example, different work processes are divided into restrictions according to the special circumstances of the work content, such as only allowing the operator bound to this work process to enter, and not allowing personnel outside this process to enter; or different restrictions are divided for different operators, such as the company's own personnel can move between various work processes, but externally introduced operators can only move between non-confidential work processes, etc.

[0067] Step S110: When the operator triggers the alarm rule, the alarm information is pushed to the management center and mapped to the operator, so that the management center can remind the operator to stop the violation or the operator can stop the violation on his own, and the alarm will be automatically cleared and an alarm record will be generated; wherein, the alarm record includes the operator information, the alarm rule triggered by the operator, and the alarm clearing status.

[0068] Generating alarm records is beneficial for the traceability of special operation process management. In addition, in order to facilitate the specific application of actual special operation process management scenarios, in addition to the method automatically alarming and de-alarming when detecting violations, this invention further provides a personnel alarm processing function, that is, receiving alarm information reported by personnel, verifying the alarm information and processing the alarm; different alarm information is set with processing priority according to the object involved, so as to quickly resolve alarm problems.

[0069] The UWB-based special operation process management alarm method disclosed in this invention also includes periodically detecting the location of all operators applying for special operation permits, so as to issue location alarms for operators who have entered the special operation area but are not in the operation process, specifically as follows: Figure 2As shown: Step S202, based on the UWB real-time positioning system, the second real-time location of several workers applying for special work permits is obtained in real time; Step S204, based on the second real-time location and the dynamic electronic fence corresponding to each work process, it is determined whether each worker is in any of the dynamic electronic fences that are in an open state, and the work process corresponding to the dynamic electronic fence they are in; Step S206, for the workers who are not in any of the dynamic electronic fences and for the workers who are determined not to belong to the work process based on all the workers bound to each work process, alarm information is pushed to the management center and mapped to the workers, so that the management center can remind the workers to enter the dynamic electronic fence of their corresponding work process and then automatically clear the alarm.

[0070] Steps S202 to S206 aim to manage the flow of workers during special operations. In addition to binding workers to work processes in real time, the method further sets the work processes that can be transferred based on whether the workers are internal or external personnel. Then, when it is detected that workers, especially external personnel, are in a non-transferable work process, an alarm message is pushed. When internal workers are detected, their transferable work processes in the special operation area are further verified. When their transferable work processes do not include the current work process, an alarm message is pushed, further refining the management of special operation processes.

[0071] Step S204 above uses the ray method to determine the dynamic electronic fence where each worker is located, thereby determining which positioning terminals are in the area and synchronously mapping them to the workers; by comparing the workers in the area with the workers matched in the work process, workers who do not belong to the work process can be identified.

[0072] Combination Figure 3 As shown, the special operation process management alarm method based on UWB disclosed in this invention further includes continuously detecting whether there are new intrusion alarms at a preset first cycle frequency, specifically including: step S302, acquiring the third location information of all personnel in the controlled area in real time based on the UWB real-time positioning system; step S304, determining the information of all personnel within the dynamic electronic fence corresponding to each operation process based on the third location information; step S306, determining whether there are non-operation personnel in the state of the dynamic electronic fence being open based on the unique identifier of the personnel information, and when there are non-operation personnel, pushing alarm information to the management center so that the management center can remind the personnel to leave the dynamic electronic fence.

[0073] After adding an intrusion alarm, this method further determines the departure status of non-operating personnel to prevent them from lingering and causing safety accidents. Specifically, it also includes: step S308, obtaining the fourth location information of the personnel based on the UWB real-time positioning system after a preset time interval according to the time of the alarm information push; step S310, determining whether the fourth location information is not within the dynamic electronic fence corresponding to any work process; if the fourth location information is not within the dynamic electronic fence corresponding to any work process, it is determined that the personnel have left the dynamic electronic fence; otherwise, an upgraded alarm information is pushed to the management center so that the management center can send an alarm command to the personnel.

[0074] like Figure 4 As shown, the special operation process management alarm method based on UWB disclosed in this invention further includes continuously detecting whether there are new departure alarms at a preset second cycle frequency. Specifically, it includes: step S402, obtaining the first time when the worker enters the dynamic electronic fence corresponding to the work process and the second time when the worker leaves the dynamic electronic fence corresponding to the work process; step S404, determining whether the worker's behavior of leaving the dynamic electronic fence is a violation based on whether a work process completion application corresponding to the worker is received within the time interval between the second time and the first time; step S406, if no work process completion application corresponding to the worker is received within the time interval, the worker's behavior of leaving the dynamic electronic fence is considered a violation, and an alarm message is pushed.

[0075] Optionally, before pushing out a worker's unauthorized departure, the system further determines whether the worker has a new task notification mapped to the management center. If the worker has a new task notification and the priority of the new task notification is higher than the current special work process, the system determines that the worker's departure is not in violation of regulations and no alarm information is pushed out.

[0076] Based on the same inventive concept as the above-described method embodiments, this application also discloses a special operation process management alarm system based on UWB, such as... Figure 5The diagram shows a framework of a UWB-based special operation process management alarm system, including: a fence setting module, used to set dynamic electronic fences corresponding to each operation process in the controlled area map model based on the special operation permit application; a binding module, used to bind each operator and corresponding operation process to each operator based on the operator's unique identifier; and a receiving and acquiring module, used to receive operation ticket approval information and acquire the first real-time location of the operator corresponding to the operation ticket based on the UWB real-time positioning system; wherein, the UWB real-time positioning system includes several positioning beacons distributed and installed within the controlled area and several devices for wearing positioning devices. The system includes a positioning terminal; a judgment module for invoking the work process and corresponding dynamic electronic fence bound to the operator, and determining whether the operator has triggered an alarm rule based on the first real-time location; wherein the dynamic electronic fence is in an open state, and the alarm rule includes multiple violations preset for the work process, the operator, and the dynamic electronic fence; and an alarm push module for pushing alarm information to the management center and mapping it to the operator when the operator triggers the alarm rule, so that the management center can remind the operator to end the violation or the operator can end the violation on their own, and the alarm can be automatically cleared and an alarm record can be generated; wherein the alarm record includes operator information, the alarm rule triggered by the operator, and the alarm clearing status.

[0077] The steps of the system for implementing the UWB-based special operation process management alarm method disclosed in the above embodiments have already been described and will not be repeated here.

[0078] For example, the UWB-based special operation process management alarm system further includes identifying and alarming all operators who have entered a special operation area but are not in the operation process. The specific execution modules include: a location acquisition module, used to acquire the second real-time location of several operators applying for special operation permits based on a UWB real-time positioning system; a first judgment module, used to determine, based on the second real-time location and the dynamic electronic fence corresponding to each operation process, whether each operator is within any of the open dynamic electronic fences, and the corresponding operation process within that dynamic electronic fence; and a determination and push module, used to push alarm information to the management center and map it to the operators who are not within any of the dynamic electronic fences and those who are determined not to belong to the operation process based on all operators bound to each operation process, so that the management center can automatically deactivate the alarm after reminding the operator to enter the dynamic electronic fence corresponding to their operation process.

[0079] For example, the UWB-based special operation process management alarm system also includes a module for identifying and alerting non-operational personnel entering the special operation area and leaving the area. Specifically, it includes: a second location acquisition module, used to acquire the third location information of all personnel in the controlled area in real time based on the UWB real-time positioning system; a fence personnel determination module, used to determine the information of all personnel located within the dynamic electronic fence corresponding to each operation process based on the third location information; and a second judgment module, used to determine whether there are non-operational personnel in the dynamic electronic fence when it is open based on the unique identifier of the personnel information, and when there are non-operational personnel, to push alarm information to the management center so that the management center can remind the personnel to leave the dynamic electronic fence.

[0080] Optionally, the UWB-based special operation process management alarm system also includes a non-operation personnel departure confirmation module to prevent non-operation personnel from lingering and causing safety accidents. Specifically, it includes: a third location acquisition module, used to acquire the fourth location information of the personnel based on the time of the alarm information push and after a preset time interval using the UWB real-time positioning system; a third judgment module, used to determine whether the fourth location information is not within the dynamic electronic fence corresponding to any operation process; if the fourth location information is not within the dynamic electronic fence corresponding to any operation process, it is determined that the personnel have left the dynamic electronic fence; otherwise, an escalation alarm information is pushed to the management center so that the management center can send an alarm command to the personnel.

[0081] The UWB-based special operation process management alarm system disclosed in this invention also includes operator departure alarm management. Its execution module includes: a time acquisition module, used to acquire the first time when the operator enters the dynamic electronic fence corresponding to the work process and the second time when the operator leaves the dynamic electronic fence corresponding to the work process; and a fourth judgment module, used to determine whether the operator's departure from the dynamic electronic fence is a violation based on whether a work process completion application corresponding to the operator is received within the time interval between the second time and the first time; if no work process completion application corresponding to the operator is received within the time interval, the operator's departure from the dynamic electronic fence is considered a violation, and an alarm message is pushed.

[0082] The special operation process management alarm method and system based on UWB of this invention uses a UWB real-time positioning system to locate personnel during special operations, and the real-time position accuracy of personnel can be controlled within 3m. By accurately identifying and judging the violations of personnel, the technical effect of improving the accuracy of special operation process control is achieved, thereby enabling more reliable implementation of the safety production responsibility system and reducing the risks of special operations.

[0083] Based on the same inventive concept as the above method embodiments, this application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the electronic device implements the UWB-based special operation process management alarm method in the above embodiments.

The program storage area may store the operating system and programs required for running instant messaging functions, etc.; the data storage area may store various instant messaging information and operation instruction sets, etc. Memory 201 may be volatile memory, such as random-access memory (RAM); memory 201 may also be non-volatile memory, such as read-only memory, flash memory, hard disk drive (HDD), or solid-state drive (SSD); or memory 201 may be any other medium capable of carrying or storing a desired computer program in the form of instructions or data structures, and accessible by a computer, but is not limited thereto. Memory 201 may be a combination of the above-mentioned memories.

[0086] Processor 202 may include one or more central processing units (CPUs) or digital processing units, etc. Processor 202 is used to implement the above-mentioned audio data processing method when calling the computer program stored in memory 201.
