Description

Technical Field

[0001] The present application relates to the technical field of hot work supervision, and in particular to a hot work control system and method. Background Art

[0002] Hot work refers to non-routine work that may produce flames, sparks, or hot surfaces at the work site outside of process facilities that directly or indirectly produce open flames, including electric welding, gas welding (cutting), blowtorches, electric drills, grinding wheels, sandblasting machines, etc.

[0003] Hot work is one of the common means of inspection and maintenance, and it is also a link where accidents are prone to occur. In recent years, many serious and major accidents have occurred due to illegal hot work, especially in the field of hazardous chemicals, where illegal operations, working without a license, non-standard operations, and failure to implement safety protection measures often occur. In order to further standardize hot work behaviors, effectively prevent and curb accidents caused by illegal hot work and non-standard hot work, it is of great significance to further strengthen the safety management and control level of hot work.

[0004] At present, some hazardous chemical enterprises are still using paper hot work permits, which have problems such as first work and then approval, lax verification of operator's operating license, unlicensed operation, untimely or no reporting, and inability to trace back the operation process, which is not conducive to supervision. Especially in chemical parks, timely grasping the hot work situation of each enterprise and conducting effective supervision are important means and ways to reduce the frequent occurrence of inspection and maintenance accidents. Summary of the invention

[0005] In order to solve the above problems, the present application provides a hot work control system and method.

[0006] One of the purposes of this application is to provide a hot work control system, which adopts the following technical solutions: A hot work control system, including a control platform, hot work equipment, an intelligent data acquisition device, a control ball and a gas detector. The control ball is deployed at the operation site to capture the process of hot work; The gas detector is installed in the work site to measure the concentration of combustible gas in the work site; The hot work equipment is equipped with a control module for monitoring the start and stop of the hot work equipment; The intelligent data acquisition device includes a data acquisition interface for connecting to the gas detector, a control unit for receiving information from the control module, and a communication module for uploading the collected data to the control platform; The control platform includes a hot work reporting module, an alarm module and a hot work statistical analysis module; The hot work reporting module includes a hot work ticket information module, which is used to connect to the hot work ticket of the enterprise and upload the ticket information to the hot work ticket information module; The alarm module includes an alarm record and an alarm information sending module. The alarm record module is used to store alarm records generated during the hot work process, including unauthorized hot work without approval and reporting, failure to implement hot work control requirements, inconsistency between actual operators and operation locations and operation tickets, operators without certificates or operation certificates that are not valid, enterprises not using hot work equipment with positioning and personnel information verification functions for hot work, failure to upload combustible gas detection results within the specified time, and violations during the operation process; the alarm information sending module is used to send alarm information during the operation process to the control platform; The hot work statistics analysis module includes a job quantity statistics analysis module, a job status statistics analysis module, a job location statistics analysis module, a hot work equipment start and stop statistics analysis module, and an alarm statistics analysis module; the job quantity statistics analysis module performs statistical analysis on hot work according to the three dimensions of enterprise, hot work category and operation time, and can realize the statistics of daily job quantity, weekly job quantity, monthly job quantity, job quantity in a self-selected time period, and year-on-year and month-on-month functions; the job status statistics analysis module performs statistical analysis on the hot work received by the management and control platform, including those not started, in progress and completed; the job location statistics analysis module performs statistical analysis on the hot work locations and rankings; the hot work equipment start and stop statistics analysis module performs statistical analysis according to the three dimensions of enterprise, hot work equipment category and operation time, and can realize statistical analysis on the start and stop of hot work equipment daily, weekly, monthly, and self-selected time period, as well as year-on-year, month-on-month, and operation unit; the alarm statistics analysis module classifies and counts the alarm information by alarm type and enterprise, and supports year-on-year and month-on-month functions.

[0007] By adopting the above technical solution, before the enterprise conducts hot work, it is necessary to submit a hot work ticket to the platform to report the hot work. Supervisors can know all hot work behaviors of all enterprises through the management and control platform, so that they can supervise the hot work of all enterprises. The management and control platform can visually manage and count the hot work of all enterprises, and can statistically display the hot work in the dimensions of enterprise, hot work category, hot work equipment category, and operation time, so that supervisors can know which time periods and which enterprises have more hot work, so as to facilitate subsequent precise supervision. The alarm module alarms and counts the illegal behaviors in the hot work. In the alarm statistical analysis module, supervisors can know the enterprises, reasons and frequencies of the alarms for hierarchical and classified supervision. At the same time, the hot work of all enterprises is informatized, visualized and standardized, which further standardizes the behavior of hot work, improves the level of safety control of hot work, effectively prevents and curbs accidents caused by illegal hot work and non-standard hot work, and continuously reduces safety risks.

[0008] Preferably, it further includes a personnel database, wherein the personnel database includes a database of personnel engaged in hot work and a database of supervisory personnel; The database of hot work personnel manages the basic information, operation certificate number, operation certificate validity period, verification status, and violation status of hot work personnel within the jurisdiction. The data source is the reporting, input and dynamic update of the management and control platform by hazardous chemical enterprises and third-party service enterprises within the jurisdiction; The guardian database manages the basic information, training status, training units, and violations of guardians within the jurisdiction. The data comes from reports and inputs from hazardous chemicals companies and third-party service companies within the jurisdiction, and the data is dynamically updated by the management and control platform.

[0009] By adopting the above technical solution, through the registration and management of hot work equipment, hot work personnel and supervisors, a complete hot work supervision system is established to ensure the controllability, compliance and safety of hot work, so as to achieve controllable risks in the entire hot work process.

[0010] Preferably, the hot work equipment is installed with a positioning module and a face recognition module electrically connected to the control module, the positioning module is used to indicate the position information of the hot work equipment in real time; the face recognition module is used to verify the operating personnel and the supervisory personnel.

[0011] By adopting the above technical solution, after the enterprise reports the hot work permit, the facial recognition module verifies the operators and supervisors performing the hot work, and compares whether the reported operators and supervisors are consistent with the operators and supervisors who actually perform the hot work. If they are consistent, the hot work equipment can be turned on to perform the hot work. If not, the control module controls the hot work equipment not to be turned on, so as to ensure the standardization of the hot work.

[0012] Preferably, a non-invasive load monitoring device is also included, which is installed behind the enterprise's main circuit breaker and is used to extract the steady-state characteristics, transient characteristics and harmonic characteristics of hot work equipment; and is used to detect and analyze the start-up and shutdown, operation and energy consumption information of the hot work equipment in the enterprise's total load.

[0013] By adopting the above technical solution, the non-intrusive load monitoring device supervises the company's hot work equipment and analyzes the actual use of the company's hot work equipment through steady-state characteristics, transient characteristics and harmonic characteristics, so as to grasp the company's hot work behavior and avoid the occurrence of unauthorized hot work without approval and reporting.

[0014] Preferably, the hot work statistical analysis module further comprises an operation risk analysis module, and the non-intrusive load monitoring device transmits analysis information to the operation risk analysis module, and the transmitted information includes the number of hot work equipment opened n and the start and stop time t1; The control module transmits the start and stop time t2 and the operation location m1 information of the hot work equipment to the operation risk analysis module; The enterprise hot work ticket information transmits the hot work operation time t3 and the operation location m2 to the operation risk analysis module; The operation risk analysis module performs comparative analysis, comparing n with the total number of control modules that send information; comparing t1, t2, and t3 times; and comparing m1 and m2; If the comparison results are the same, they are recorded as qualified; if the comparison results are inconsistent, the difference information is sent to the alarm module, and the alarm module sends the difference information to the management and control platform and supervisors through the alarm information sending module, and retains the record in the alarm record module.

[0015] By adopting the above technical solution, the general process of enterprises conducting hot work is to report the hot work to the control platform before the operation, and then the operator shall conduct the hot work under the supervision of the supervisor at a specific time and area. The verification of the operator and the supervisor is verified by the face recognition module on the hot work equipment to ensure that the personnel on the hot work ticket are consistent with the actual operator. The positioning module on the hot work equipment can record the location information of the hot work equipment during operation, and compare and verify it with the location information reported in the hot work ticket to ensure that the actual operation is within the reported operation range. The non-invasive load monitoring device supervises the actual operation quantity and time of the hot work equipment, and verifies and controls the actual use of the hot work equipment during the hot work. The operation risk analysis module compares and analyzes the information of the several to ensure that the actual operation behavior of the hot work is consistent with the information of the reported hot work ticket, thereby ensuring the compliance and safety of the hot work.

[0016] Preferably, after any module of the non-invasive load monitoring device, control module or enterprise hot work ticket information transmits information to the operation risk analysis module, the operation risk analysis module performs a comparison, and the objects missing in the comparison process are recorded as missing, and the difference information is sent to the alarm module. The alarm module sends the difference information to the management and control platform and supervisors through the alarm information sending module, and retains the record in the alarm recording module.

[0017] By adopting the above technical solution, the hot work activities carried out by the enterprise after reporting the hot work can be controlled through the facial recognition module and positioning module on the control ball and the hot work equipment. However, the premise is that all the hot work equipment in the enterprise are installed with the facial recognition module and the positioning module, so that the hot work can be controlled. If the enterprise has hot work equipment without the facial recognition module and the positioning module installed and uses the hot work equipment to carry out hot work without authorization, it is difficult to supervise. In order to reduce the risks caused by this situation, the non-invasive load monitoring device analyzes all the electricity consumption of the enterprise. When the enterprise has not reported the hot work, and the non-invasive load monitoring device detects the use data of the hot work equipment, the operation risk analysis module can only receive the hot work equipment data sent by the non-invasive load monitoring device, and other data is missing. The comparison data is missing. This situation indicates that there are hot work equipment in the enterprise that is not registered, that is, the facial recognition module and the positioning module are not installed. The operation risk analysis module marks this behavior and informs the supervisor through the control platform, and the supervisor verifies the actual situation of the enterprise. Through the above methods, the probability of carrying out hot work without reporting it can be reduced.

[0018] Preferably, the non-invasive load monitoring device includes a data acquisition module and a load decomposition and identification algorithm. The data acquisition module includes current and voltage sensors installed at the entrance of the power bus for collecting current and voltage data. The load decomposition and identification algorithm includes collecting transient, steady-state and harmonic data of hot work equipment, extracting characteristic parameters, decomposing the total load through a pattern recognition algorithm, and learning and training the collected hot work equipment data to establish an equipment characteristic model. Then, the real-time collected data is input into the model to identify the start, stop, operation and energy consumption information of the hot work equipment.

[0019] By adopting the above technical solution, the non-intrusive load monitoring device is mainly divided into data collection and algorithm recognition. The current and voltage data are collected by the current and voltage sensors installed at the entrance of the power bus. These data can be regarded as the superposition of the voltage and current of each power-consuming device. By decomposing the collected overall data, the operation and energy consumption information of each power-consuming device can be identified and decomposed. In turn, the start-stop, operation and energy consumption information of the enterprise's hot work equipment can be accurately grasped.

[0020] Preferably, the hot work reporting module also includes a hot work spot check module and an operator's operating certificate verification module. The hot work spot check module can conduct spot checks on any operation, including whether the operator has an operating certificate, whether the operating certificate is valid, whether the flammable gas exceeds the standard, and whether the on-site operator has any violations. The functions of the operator's operating certificate verification module include that after the enterprise reports the hot work, the management and control platform verifies the operating certificate by calling the special operation operating certificate query interface of the emergency management department and displays the verification results, and prompts the operating certificate that is about to expire.

[0021] By adopting the above technical solution, supervisors can conduct spot checks and control on all hot work operations reported and ongoing by all enterprises to ensure the compliance and safety of hot work operations.

[0022] Preferably, the control platform also includes a hot work equipment control module, which is used to send control information to the control module of the hot work equipment, and the hot work equipment control module includes a regional control module, a time control module and a hot work equipment database; the regional control module is used to select the area to be controlled, that is, the control module that controls all the hot work equipment in the area, and the time control module refers to the time to be controlled, that is, the control module that controls all the hot work equipment within the time period. The hot work equipment control module sends instructions to the control modules of all the hot work equipment in a certain area and a certain time period through the regional control module and the time control module to control whether the hot work equipment can be turned on; the hot work equipment database contains all control modules, and the hot work equipment control module can send instructions to all the control modules in the database independently or in batches to control whether the hot work equipment can be turned on; The hot work reporting module also includes a special application module for hot work. The enterprise sends special application information for hot work to the management and control platform through the special application module for hot work. The special application information for hot work includes hot work ticket information and the reason for applying for release of control.

[0023] By adopting the above technical solution, hot work is not allowed in certain special periods or in certain special areas. At this time, the supervisor can select the corresponding area and time through the hot work equipment control module, and send instructions to the control modules of all hot work equipment in the area or time period, so that they cannot be turned on in the corresponding time period and area, thereby realizing the control of hot work. When the enterprise really needs to perform hot work due to special circumstances, it can send an application for lifting control to the control platform through the special application module for hot work. After receiving the application, the supervisor determines whether to lift the control based on the reason for lifting the control, and sends instructions to the hot work equipment that needs to be lifted through the hot work equipment control module to control whether the hot work equipment can be turned on.

[0024] Another object of the present application is to provide a method for controlling hot work, which adopts the following technical solution: A method for hot work control, using the hot work control system, includes hot work control steps and operator operation certificate verification steps. The hot work control steps include: S1. After the control platform receives the hot work ticket information reported by the enterprise, it stores and displays it, and sends it to the control module; S2. The control module determines whether the hot work ticket has been reported based on the positioning information, application time information and the reporting flag. If it has been reported, step S3 is executed; if it has not been reported, the non-intrusive load monitoring device is read to see whether it has analyzed the hot work equipment load. If there is hot work equipment load information, an alarm message that the hot work ticket has not been reported is sent to the supervisor; if there is no hot work equipment load information, there is no hot work; S3. Determine whether the hot work information is in the control period or control area. If so, keep the hot work equipment in the closed state, and send an alarm message to the supervisor that the hot work control requirements have not been implemented; if not in the control period or control area, execute step S4; S4. The control module reads the positioning module information to determine whether there is hot work equipment positioning information. If so, execute step S5. If not, read the non-intrusive load monitoring device to determine whether the hot work equipment load is analyzed. If there is hot work equipment load information, send a warning message to the supervisor that the enterprise has not used the hot work equipment with positioning and personnel information verification functions for hot work; S5. Determine whether the work location and work time in the hot work ticket are consistent with the location information and time information of the hot work equipment. If they are consistent, execute step S6. Otherwise, send an alarm message to the supervisor that the hot work time and location information are inconsistent with the reported information, and keep the hot work equipment in a closed state; S6. The on-site supervisor should confirm in front of the face recognition module. If the verification is passed, proceed to step S7. Otherwise, an alarm message is sent to the supervisor that the supervisor of the hot work is inconsistent with the reported information; S7. After verification and confirmation by the supervisor, the combustible gas concentration value within the working range shall be detected, and the location description of the detection point and the measured concentration value shall be uploaded to the control platform; S8. The hot work personnel shall verify the information through the face recognition module. After passing the verification, it shall be determined whether the time interval between the combustible gas concentration data upload time and the confirmation time of the hot work personnel exceeds 30 minutes. If so, the combustible gas concentration test shall be re-performed, and then step S9 shall be executed; if the verification of the operator fails, an alarm message of inconsistency between the hot work personnel and the reported information shall be sent to the supervisor, and the hot work equipment shall be kept in the closed state; S9. Start the hot work equipment, start the on-site control ball to monitor the whole process of the hot work and upload it to the supervision platform. The supervision platform analyzes the safety protection measures worn by the operators and the violations. If there are any violations, the corresponding violation alarm information will be sent to the supervisor; if there are no violations, execute step S10; S10. After completion of the project, the acceptance results will be uploaded to the management and control platform; The steps of verifying the operator's operating certificate include: X1. Enter the "hot work spot check" module, select the operator to be verified, and click "verify"; X2. The control platform will use the "identity information" in the hot work ticket as a request parameter to request the hot work backend service. The backend service will verify the parameters and check whether the name and ID number of the operator have been filled in; X3. After checking that the parameters of the hot work service are correct, initiate a login verification to the "Emergency Management Department Special Operations Operation Certificate and Safety Production Knowledge and Management Ability Assessment Qualification Information Query Platform". The information query platform returns a login verification code, the back-end service identifies the verification code, and obtains login permission information; X4. The hot work service uses the "identity information" in the work ticket as a request parameter to request the information query platform to query the verification results and obtain the verification results; X5. The hot work service returns the results to the management and control platform for display.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the control and monitoring of hot work equipment and the confirmation and verification of operators before operations, it is possible to prevent the occurrence of situations such as unauthorized hot work without approval and reporting, operators working without certificates or operating certificates that are not valid. It can effectively reduce the number of illegal behaviors such as the approval time of hot work tickets of enterprises being later than the operation time, failure to upload the location and time of flammable gas detection as required, and unauthorized change of the operation location, further eliminate regulatory blind spots, fundamentally eliminate accident hazards, and fundamentally solve the problem.

[0026] 2. It is conducive to the supervisory personnel to quickly grasp the information such as the reporting of hot work, progress of the operation, violations, etc. in the jurisdiction, as well as whether there are any violations such as unauthorized hot work without reporting, operators not holding certificates or the operation certificates are not valid, and unauthorized changes of the work location, so as to provide data support for the supervisory department's precise supervision and law enforcement.

[0027] 3. Through the whole process control of hot work, we can further standardize the approval of enterprise operation tickets, the need for certification, the operation process, the implementation of safety operating procedures and other behaviors, and reduce the probability of accidents caused by hot work.

[0028] 4. It can control and manage hot work in special periods and special areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] Example 1

[0032] The embodiment of the present application discloses a hot work control system, which mainly includes a control platform for data analysis, management and display and a collection device installed in the enterprise for collecting data. The control platform includes an enterprise end, an APP mobile end and a supervision platform. The enterprise transmits the hot work ticket information to the supervision platform through the enterprise end, and the supervision platform controls all hot work behaviors.

[0033] Reference Figure 1 The management and control platform includes a personnel database, a hot work reporting module, an alarm module and hot work statistical analysis.

[0034] The personnel database includes a database of personnel engaged in hot work and a database of supervisors. The database of personnel engaged in hot work manages the basic information, operator certificate number, operator certificate validity period, verification status, and violation status of personnel engaged in hot work within the jurisdiction. The data comes from reports, inputs, and dynamic updates of the management and control platform from companies engaged in hazardous chemicals and third-party services within the jurisdiction. The database of supervisors manages the basic information, training status, training units, and violation status of supervisors within the jurisdiction. The data comes from reports, inputs, and dynamic updates of the management and control platform from companies engaged in hazardous chemicals and third-party services within the jurisdiction.

[0035] The hot work reporting module includes hot work ticket information and hot work spot check module. The hot work ticket module is mainly connected to the hot work ticket information on the enterprise side. After the enterprise issues the ticket, it uploads the ticket information to the module for reporting and display; the hot work spot check module can conduct spot checks on any operation, including whether the operator has an operation certificate, whether the operation certificate is valid, whether the flammable gas exceeds the standard, whether the on-site operator has any violations, etc., and the operator's operation certificate is verified. After the enterprise reports the hot work, the management and control platform verifies the operation certificate by calling the special operation operation certificate query interface of the emergency management department, and prompts the operation certificate that is about to expire.

[0036] The alarm module includes an alarm record module and an alarm information sending module. The alarm record module is used to store alarm records generated during hot work operations, including unauthorized hot work operations without approval and reporting, failure to implement hot work operation control requirements, inconsistency between actual operating personnel and working locations and work tickets, operating personnel not holding certificates or the operating certificates are not valid, the company does not use hot work equipment with positioning and personnel information verification functions for hot work operations, failure to upload combustible gas detection results within the specified time, and violations during the operation. The alarm information sending module is used to send alarm information during the operation to the enterprise side, the supervision platform and the supervisor's APP mobile side. The enterprise can view it by entering the account password to facilitate timely discovery and processing of relevant alarms.

[0037] The hot work statistics analysis module includes the operation quantity statistics analysis module, the operation status statistics analysis module, the operation location statistics analysis module, the hot work equipment start and stop statistics analysis module, and the alarm statistics analysis module; the operation quantity statistics analysis module conducts statistics analysis on hot work according to the three dimensions of enterprise, hot work category and operation time, and can realize the statistics of daily operation quantity, weekly operation quantity, monthly operation quantity, operation quantity in the selected time period, as well as year-on-year and month-on-month functions; the operation status statistics analysis module conducts statistics analysis on the hot work received by the management and control platform, including those not started, in progress and completed; the operation location statistics analysis module conducts statistics analysis on the hot work locations and rankings; the hot work equipment start and stop statistics analysis module conducts statistics analysis according to the three dimensions of enterprise, hot work equipment category and operation time, and can realize statistics analysis on the start and stop of hot work equipment daily, weekly, monthly, and self-selected time period, as well as year-on-year, month-on-month, operation unit, and hot work equipment category; the alarm statistics analysis module classifies and statistics the alarm information by alarm type and enterprise, and supports year-on-year and month-on-month functions.

[0038] The collection device includes hot work equipment, intelligent data collection device, non-intrusive load monitoring module, control ball and gas detector. An intelligent control module is installed on the hot work equipment to control the hot work equipment and collect data. Hot work equipment refers to the equipment that enterprises need to use when performing hot work, including but not limited to electric welders, gas welders, blowtorches, electric drills, grinding wheels, sandblasting machines and other equipment.

[0039] The surveillance camera and gas detectors are deployed at the company's work site, i.e. the hot work area. The surveillance camera takes photos and uploads the hot work process, which is convenient for archiving, intelligent video analysis and random inspection by supervisors. The gas detector monitors the concentration of combustible gas at the hot work site in real time to ensure the safety of the working environment.

[0040] The intelligent data acquisition device includes a control unit, a data acquisition interface, and a communication module. The control unit is used to receive information from the hot work equipment control module, and to control data acquisition and data upload; the data acquisition interface is mainly used to connect to the company's online combustible gas detector, supporting Modbus, TCP, OPC and other protocols; the communication module is used to upload the collected data to the management and control platform.

[0041] The intelligent control module includes a control module, a positioning module and a face recognition module installed on the hot work equipment. The positioning module locates and monitors the working position of the hot work equipment, and the face recognition module is used to verify whether the operator and the supervisor are consistent with the hot work ticket reporting information. The control module is electrically connected to the face recognition module. The control module is used to control the start and stop of the hot work equipment. If the face recognition module fails to pass the verification (including the inconsistency of the operator in the work ticket approval, etc.), the hot work equipment cannot be started.

[0042] The non-intrusive load monitoring device is installed behind the main circuit breaker of the enterprise, and is used to extract the steady-state characteristics, transient characteristics and harmonic characteristics of the hot work equipment. It is mainly divided into data acquisition and load decomposition and identification algorithms. The current and voltage data are collected by the current and voltage sensors installed at the entrance of the power bus, and the transient, steady-state and harmonic data of the hot work equipment are collected, and the characteristic parameters are extracted. The total load is decomposed through the pattern recognition algorithm, and the collected hot work equipment data is studied and trained to establish the equipment characteristic model. Then the real-time collected data is input into the model to identify the start, stop, operation and energy consumption information of the hot work equipment.

[0043] Data acquisition: Use current, voltage and other sensors to collect current and voltage signals in the main circuit. By synchronously measuring the collected current and voltage signals, the circuit power (including active power, reactive power and apparent power), power factor and other parameters can be calculated.

[0044] Load feature extraction: The collected raw current and voltage signals contain comprehensive information about all electrical equipment in the enterprise, and it is necessary to further extract parameters that can reflect the characteristics of hot work equipment. Common characteristic parameters include transient characteristics, steady-state characteristics, and harmonic characteristics.

[0045] Load decomposition and identification algorithm: Utilize the extracted characteristic parameters and apply algorithms based on machine learning, pattern recognition or source separation to decompose the total load into the load of each electrical equipment, and then identify the start, stop, operation and energy consumption of the hot work equipment.

[0046] The main purpose of the non-invasive load monitoring device after training is to detect and analyze the start-up, shutdown, operation and energy consumption information of the hot work equipment in the total load of the enterprise, so as to understand the hot work behavior of the enterprise and avoid the occurrence of hot work without approval and reporting.

[0047] The hot work statistical analysis module also includes an operation risk analysis module. The operation risk analysis module is mainly used to control hot work equipment that is not equipped with an intelligent control module, so as to reduce the probability of carrying out hot work without reporting it.

[0048] The non-intrusive load monitoring device analyzes the information and transmits it to the operation risk analysis module. The information transmitted includes the number of hot work equipment opened n and the start and stop time t1.

[0049] The control module transmits the start and stop time t2 and the operation location m1 information of the hot work equipment to the operation risk analysis module.

[0050] The enterprise hot work ticket information transmits the hot work operation time t3 and operation location m2 to the operation risk analysis module; The operation risk analysis module performs a comparison analysis, comparing n with the total number of control modules that send information; comparing t1, t2, and t3 times; and comparing m1 and m2. If the comparison results are the same, it is recorded as qualified; if the comparison results are inconsistent, the difference information is marked and recorded as a risk. After any module of the non-intrusive load monitoring device, control module, or enterprise hot work ticket information transmits information to the operation risk analysis module, the operation risk analysis module performs a comparison, and the missing objects in the comparison process are recorded as missing, and the difference information is marked and recorded as high risk.

[0051] There are two types of hot work performed by enterprises. One is the hot work after the hot work ticket information has been reported, and the other is the hot work performed without reporting the hot work ticket.

[0052] After the enterprise reports the hot work, the main contents of the hot work verification are: the operation location, operation time, operator and operation equipment. The operation risk analysis module compares m1 and m2 to ensure that the actual operation address of the hot work equipment is the same as the reported address. The operation risk analysis module compares t1, t2, and t3 to ensure that the actual operation time is the same as the reported time. The operation risk analysis module compares n with the total number of control modules that send information to ensure that the operation equipment, that is, the hot work equipment in the actual operation, is the same as the reported hot work equipment. The face recognition module on the hot work equipment compares the operators to ensure that the actual operators are the same as the reported operators. The operation risk analysis module counts the comparison results. If the comparison results are consistent, it means that the enterprise's operation is in compliance with the regulations and is recorded as qualified. If the comparison results are inconsistent, it means that the enterprise has violated the regulations in the hot work, it will be recorded as a risk, and the difference information will be marked and sent to the alarm module at the same time. The alarm module sends alarm information to the enterprise end, APP mobile end and supervision platform to facilitate subsequent precise supervision.

[0053] When an enterprise conducts hot work without reporting it, since there is no hot work ticket uploaded to the management and control platform, the operation risk analysis module and the non-invasive load monitoring device cooperate with each other to control this behavior.

[0054] When an enterprise fails to report hot work and carries out hot work without authorization, the power load information of the hot work equipment is recorded and analyzed in real time through the non-invasive load monitoring device and transmitted to the operation risk analysis module. Since the enterprise has not reported the hot work ticket, the risk operation analysis module only has the information transmitted by the non-invasive load monitoring device. In the absence of other information during comparison, an unreported hot work alarm message is sent to the supervisor.

[0055] The risk operation analysis module supervises and marks the hot work reported by enterprises and those carried out privately, thereby conducting more comprehensive control over the hot work of enterprises and reducing the risks of hot work.

[0056] The management and control platform also includes a hot work equipment management and control module, which is used to send management and control information to the control module of the hot work equipment. The hot work equipment management and control module includes an area management module, a time management module and a hot work equipment database.

[0057] The area control module is used to select the area to be controlled, that is, the control module that controls all hot work equipment in the area. The time control module refers to the time to be controlled, that is, the control module that controls all hot work equipment within the time period. The hot work equipment control module sends instructions to the control modules of all hot work equipment in a certain area and a certain time period through the area control module and the time control module to control whether the hot work equipment can be turned on. During certain special periods or in a certain special area, hot work is not allowed. At this time, the supervisor can select the corresponding area and time through the hot work equipment control module, and send instructions to the control modules of all hot work equipment in the area and time period, so that they cannot be turned on in the corresponding area and time period, thereby realizing hot work control.

[0058] The hot work equipment database contains all control modules, and the management and control module can independently / batch send instructions to all control modules in the database to control whether the hot work equipment can be turned on. The hot work reporting module also includes a special application module for hot work. The enterprise sends special application information for hot work to the management and control platform through the special application module for hot work. The special application information for hot work includes the hot work ticket information and the reason for applying for lifting the control. When an enterprise does have special circumstances that require hot work during control, it can send special application information for hot work to the management and control platform through the special application module for hot work. After receiving the application, the supervisor determines whether to lift the control based on the reason for lifting the control, and sends instructions to the hot work equipment that needs to be lifted through the hot work equipment database to control whether the hot work equipment can be turned on.

[0059] Example 2

[0060] The embodiment of the present application discloses a method for controlling hot work, which uses the above-mentioned hot work control system and includes a hot work control step and a step of verifying the operator's operating certificate.

[0061] Reference Figure 2 ,The hot work control steps include, S1. After the control platform receives the hot work ticket information reported by the enterprise, it stores and displays it, and sends it to the control module; S2. The control module determines whether the hot work ticket has been reported based on the positioning information, application time information and the reporting flag. If it has been reported, step S3 is executed; if it has not been reported, the non-intrusive load monitoring device is read to see whether it has analyzed the hot work equipment load. If there is hot work equipment load information, an alarm message that the hot work ticket has not been reported is sent to the supervisor; if there is no hot work equipment load information, there is no hot work; S3. Determine whether the hot work information is in the control period or control area. If so, keep the hot work equipment in the closed state, and send an alarm message to the supervisor that the hot work control requirements have not been implemented; if not in the control period or control area, execute step S4; S4. The control module reads the positioning module information to determine whether there is hot work equipment positioning information. If so, execute step S5. If not, read the non-intrusive load monitoring device to determine whether the hot work equipment load is analyzed. If there is hot work equipment load information, send a warning message to the supervisor that the enterprise has not used the hot work equipment with positioning and personnel information verification functions for hot work; S5. Determine whether the work location and work time in the hot work ticket are consistent with the location information and time information of the hot work equipment. If they are consistent, execute step S6. Otherwise, send an alarm message to the supervisor that the hot work time and location information are inconsistent with the reported information, and keep the hot work equipment in a closed state; S6. The on-site supervisor should confirm in front of the face recognition module. If the verification is passed, proceed to step S7. Otherwise, an alarm message is sent to the supervisor that the supervisor of the hot work is inconsistent with the reported information; S7. After verification and confirmation by the supervisor, the combustible gas concentration value within the working range shall be detected, and the location description of the detection point and the measured concentration value shall be uploaded to the control platform; S8. The hot work personnel shall verify the information through the face recognition module. After passing the verification, it shall be determined whether the time interval between the combustible gas concentration data upload time and the confirmation time of the hot work personnel exceeds 30 minutes. If so, the combustible gas concentration test shall be re-performed, and then step S9 shall be executed; if the verification of the operator fails, an alarm message of inconsistency between the hot work personnel and the reported information shall be sent to the supervisor, and the hot work equipment shall be kept in the closed state; S9. Start the hot work equipment, start the on-site control ball to monitor the whole process of the hot work and upload it to the supervision platform. The supervision platform analyzes the safety protection measures worn by the operators and the violations. If there are any violations, the corresponding violation alarm information will be sent to the supervisor; if there are no violations, execute step S10; S10. After completion of the project, the acceptance results will be uploaded to the management and control platform.

[0062] The control platform integrates detection models, rule systems, and visual big models, etc. It uses the streaming protocol to obtain the stream from the port of the network camera to form a continuous video sequence as the input of intelligent analysis. The detection model performs scene analysis on the video sequence and uses artificial intelligence technology to infer the detection target, including violations, risks, etc. Based on the detection target and alarm definition, the rule system determines whether an alarm is currently required and forwards the alarm result to the visual big model. Finally, the visual big model reviews the alarm result again, eliminates false alarms, and pushes the review results to the upper-level platform.

[0063] Video Analysis Process Z1. Video Preprocessing Denoising: Use filtering algorithms to remove noise interference in the video and improve picture quality.

[0064] Enhancement: Adjust the brightness, contrast, color, etc. of the video to highlight key information and make subsequent analysis more accurate.

[0065] Format conversion: Convert the captured original video format into a standard format that is easy to analyze and process.

[0066] Z2. Object detection: Use deep learning-based object detection algorithms such as YOLOv7, YOLOPose, EfficientDet, ViT, etc. to identify and locate objects in video frames, such as people, vehicles, animals, specific objects, etc., and determine the category and location information of the target.

[0067] Z3. Feature extraction Visual features: Extract shape, color, texture and other features through edge detection, contour extraction and other methods of deep learning models (such as convolutional neural networks).

[0068] Motion characteristics: Analyze the target's motion trajectory, speed, acceleration and other information, usually achieved using optical flow methods, trajectory tracking algorithms, etc.

[0069] Z4. Behavior analysis: Based on the target's movement pattern, posture changes, interactions and other information, rule-based methods or machine learning algorithms (such as recurrent neural networks, long short-term memory networks, etc.) are used to implement behavior analysis and determine the target's behavioral actions, such as walking, running, waving, falling, etc.

[0070] Z5. Event recognition: Combine the target's behavior and scene information, and use machine learning or deep learning models to identify specific events or abnormal situations, such as sparks, smoke, and effusion.

[0071] Z6. Model training and optimization: Use a large amount of labeled video data to train the intelligent video analysis model, continuously adjust the model parameters, improve the accuracy, robustness and generalization ability of the model, and continuously optimize and update the model.

[0072] The steps for verifying the operator's operating certificate include: X1. The supervisor enters the "Hot Work Spot Check" module on the supervision platform, selects the operator to be verified, and clicks "Verify"; X2. The control platform will use the "identity information" in the hot work ticket as a request parameter to request the hot work backend service. The backend service will verify the parameters and check whether the name and ID number of the operator have been filled in; X3. After checking that the parameters of the hot work service are correct, initiate a login verification to the "Emergency Management Department Special Operations Operation Certificate and Safety Production Knowledge and Management Ability Assessment Qualification Information Query Platform". The information query platform returns a login verification code, the back-end service identifies the verification code, and obtains login permission information; X4. The hot work service uses the "identity information" in the work ticket as a request parameter to request the information query platform to query the verification results and obtain the verification results; X5. The hot work service returns the results to the management and control platform for display.
