Description

[0001] This application is a divisional application of Chinese Patent Application No. 202311494158.4, entitled "An Engineering Hot Work Operation Permission Management System and Method", filed on November 9, 2023, the contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of construction safety technology, specifically to a management system and method for hot work operation permissions in engineering projects. Background Technology

[0003] Hot work refers to temporary work that may generate sparks, flames, or hot surfaces. Common hot work includes electric welding, gas welding (thermal cutting), electric drilling, grinding wheels, and blowtorches. These types of work can easily cause fires, explosions, electric shocks, and burns, and the light radiation can easily cause eye and skin damage. Therefore, hot work permits must be obtained before any hot work can be carried out on construction sites. The approver must verify on-site whether the conditions for hot work are met. The approval includes checking whether flammable and explosive materials are present on site, whether there is work at height, whether fire extinguishing facilities are available, whether the hot work tools are safe, and whether the wiring is correctly connected.

[0004] Because the hot work permit application process is quite cumbersome, it is difficult to ensure that the person applying for the hot work permit and the person performing the hot work are the same person. Furthermore, the approved hot work time is often difficult to accurately control during actual hot work operations, leading to hot work being carried out outside the approved time, further increasing the difficulty of hot work supervision. Therefore, it is essential to strictly control the accuracy of hot work personnel and hot work time to reduce the incidence of safety accidents. Summary of the Invention

The secondary switch control module is used to receive the secondary control command sent by the image processing terminal, and if the secondary control command is an opening command, to send a first opening command to the power supply terminal of the hot work equipment. The three-level switch control module is used to send a second start command to the power supply terminal of the hot work equipment if the actual time reaches the start time of the hot work operation, and to send a stop command to the power supply terminal of the hot work equipment if the actual time reaches the end time of the hot work operation. The power supply terminal of the hot work equipment is used to connect the hot work equipment to the power supply if a first opening command and a second opening command are received, and to disconnect the hot work equipment from the power supply if a closing command is received. The four-level switch control module is used to manually turn hot work equipment on or off.

[0010] In one or more optional embodiments, the engineering hot work permission management system further includes a first display terminal set on the hot work equipment, the first display terminal being connected to the server and used to receive online hot work application information sent by the server.

[0013] In one or more optional embodiments, the first approval result information includes approval opinion, approval reason, approver, approval time, and approval opinion supporting electronic signature.

[0014] In one or more alternative embodiments, the second approval result information includes an approval result confirmation opinion.

[0015] Secondly, this application also discloses a method for managing hot work permits in engineering projects, used to implement the hot work permit management system as described in the first aspect, comprising: The application terminal initiates an online hot work application based on the trigger command and generates hot work application information; The server receives the hot work application information and sends the first approval instruction to the first approval terminal. The first approval terminal receives the approval instruction, reviews the hot work application information and the hot work site, and generates the first approval result information; The server receives the first approval result information and sends the second approval instruction to the second approval server; The second approval terminal receives the second approval instruction, reviews the hot work application information and the hot work site, and generates the second approval result information; The server receives the second approval result information and sends a first-level control command to the hot work equipment switch control terminal. If the first-level control command is an opening command, the hot work equipment switch control terminal sends an image acquisition command to the image processing terminal. The image processing unit collects facial information of the hot work operator and compares it with the online hot work application information; If the operator's facial information matches the online hot work application information, and the time meets the hot work start time, the hot work equipment switch control terminal sends an start command to the hot work equipment power supply terminal.

Detailed Implementation

[0020] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0024] Taking welding as an example, the inventors discovered that before hot work operations, approvers need to go to the site to verify the applicant's information and check the availability of fire-fighting equipment and the cleanliness of the work area. When approving hot work applications, the applicant and the actual operator must be the same person. Currently, there is a lack of a complete system to implement this process, making it difficult to ensure that the applicant and the operator are the same person. Furthermore, the actual hot work time is often difficult to control, potentially leading to hot work operations occurring outside the approved timeframe, further increasing the difficulty of hot work supervision.

[0025] To address the problems existing in the aforementioned related technologies, this application discloses an engineering hot work permission management system and method. The following provides a detailed description of various embodiments of the engineering hot work permission management system and method in this application.

[0026] Firstly, referring to Figure 1 This application discloses an engineering hot work permission management system, including a server, and an application terminal, a first approval terminal, a second approval terminal, a hot work equipment switch control terminal, an image processing terminal, and a hot work equipment power supply terminal connected to the server.

[0027] Specifically, the application terminal initiates an online hot work application based on a trigger command, generates online hot work application information, and sends it. The server receives and stores the online hot work application information, sends a first approval command to the first approval terminal and receives the first approval result information sent by the first approval terminal, sends a second approval command to the second approval terminal and receives the second approval result information sent by the second approval terminal, sends a first-level control command to the hot work equipment switch control terminal based on the second approval result information, and sends the online hot work application information to the image processing terminal and the hot work equipment switch control terminal. The first approval terminal receives the first approval command and sends the first approval result information to the server; the second approval terminal receives the second approval command and sends the second approval result information to the server.

[0028] In an optional embodiment, the server stores information on all possible applicants. When an applicant initiates an online hot work application through the application terminal at the corresponding information location, online hot work application information is generated. Specifically, the online hot work application information includes the work team using the hot work, the location of the hot work, the type of hot work, the start and end times of the hot work operation, the personnel involved in the hot work, the hot work supervisor, whether fire-fighting equipment is available, and whether combustible materials at the work site have been cleared. After receiving the online hot work application information, the server issues a first approval instruction to the first approval terminal, which conducts on-site review and generates first approval result information.

[0029] In an optional embodiment, the "hot work team" refers to the team or unit to which the person in charge of the hot work operation belongs; the "hot work location" refers to the specific location where the hot work operation will be carried out; the "hot work type" refers to the type of hot work, such as electric welding, gas welding, argon arc welding, plasma welding, electric drill, grinding wheel, pneumatic pick, etc.; the "hot work start and end time" refers to the specific start and end time of the hot work operation; the "hot work personnel" refers to the operators who carry out the hot work operation, specifically including the identity information and facial information of all hot work personnel; and the "hot work supervisor" refers to the personnel responsible for monitoring and inspecting the hot work site.

[0030] Specifically, during the on-site review at the first approval end, the first approval end will take photos of the fire-fighting equipment configuration and the cleanup status of the work area to generate the first approval result information, and then upload it to the server. The first approval result information includes the approval opinion, approval reason, approver, approval time, and the approval opinion supports electronic signature.

[0031] In an optional embodiment, after receiving the second approval instruction from the server, the second approval terminal further reviews the first approval result information, the hot work application information, and the hot work site, generates second approval result information, and uploads it to the server. It should be noted that the second approval result information is a confirmation opinion on the approval result, which can be confirmed by selecting "confirm" or entering a confirmation opinion. Setting up a two-level review helps ensure the accuracy of the review and avoids errors on one side affecting the compliance of the hot work operation.

[0032] In an optional embodiment, the application end can be a personal computer, smartphone, tablet, or other terminal device of the person applying for hot work; correspondingly, the first approval end and the second approval end can be a personal computer, smartphone, tablet, or other terminal device of the person approving the hot work; and the server end can be a main server.

[0033] In an optional embodiment, the first approval instruction and the second approval instruction sent by the server may specifically be SMS messages, emails, or telephone calls sent to the first approval terminal and the second approval terminal, respectively, to remind the personnel responsible for hot work approval to conduct the approval.

[0034] Furthermore, the server sends a first-level control command to the hot work equipment switch control terminal based on the second approval result information. The hot work equipment switch control terminal is used to receive the first-level control command and online hot work application information sent by the server, and if the first-level control command is an opening command, it sends an image acquisition command to the image processing terminal, and receives the second-level control command sent by the image processing terminal. If the second-level control command is an opening command and the time meets the hot work start time, it sends an opening command to the hot work equipment power supply terminal, and manually turns the hot work equipment on or off.

[0035] In an optional embodiment, the hot work equipment switch control terminal includes a primary switch control module, a secondary switch control module, a tertiary switch control module, and a quaternary switch control module. The primary switch control module receives a primary control command sent by the server, and if the primary control command is an activation command, sends an image acquisition command to the image processing terminal. The secondary switch control module receives a secondary control command sent by the image processing terminal, and if the secondary control command is an activation command, sends a first activation command to the hot work equipment power supply terminal. The tertiary switch control module sends a second activation command to the hot work equipment power supply terminal if the hot work start time has arrived, and sends a shutdown command to the hot work equipment power supply terminal if the hot work end time has arrived. The hot work equipment power supply terminal connects to the power supply if it receives the first and second activation commands, and disconnects the power supply to the hot work equipment if it receives the shutdown command. The quaternary switch control module is used to manually activate or deactivate the hot work equipment.

[0036] Specifically, if the second approval result is "approved," the primary control command sent by the server to the hot work equipment switch control terminal is an "open" command. The primary switch control module receives the "open" command and sends an image acquisition command to the image processing terminal. The image processing terminal acquires the operator's facial information, compares it with the online hot work application information, and then sends a secondary control command to the secondary switch control module based on the recognition result.

[0037] Furthermore, if the identification result is successful, the secondary switch control module sends a first start command to the power supply terminal of the hot work equipment. Simultaneously, when the actual work start time arrives, the tertiary switch control module sends a second start command to the power supply terminal of the hot work equipment. Only after the power supply terminal of the hot work equipment receives the first and second start commands can the hot work equipment be normally turned on or off. It should be noted that the tertiary switch control module is externally connected to a timing module, which can issue corresponding start and stop commands based on the time nodes and the start and end times of the hot work operation in the hot work application information. In addition, there is no restriction on the order in which the first and second start commands are issued; that is, facial recognition can pass first, the hot work start time can arrive first, or both commands can arrive simultaneously. This imposes multiple restrictions on the triggering requirements of hot work operations. On the one hand, it avoids the phenomenon of mismatch between the hot work operator and the applicant, and strictly limits the hot work operation time to within the application time. On the other hand, by adding various conditions for starting and stopping hot work operations, it prevents safety accidents caused by operators accidentally touching the equipment.

[0038] In an optional embodiment, the hot work equipment may be further equipped with three indicator lights, corresponding to a primary switch control module, a secondary switch control module, and a tertiary switch control module. Specifically, when the second approval result information is approved, the indicator light corresponding to the primary switch control module illuminates; when facial recognition is successful, the indicator light corresponding to the secondary switch control module illuminates; and when the actual time reaches the start time for the hot work operation, the indicator light corresponding to the tertiary switch control module illuminates. Operators can use these indicator lights to determine the appropriate time to start the hot work equipment, improving the efficiency of hot work operations.

[0039] In an optional embodiment, the four-level switch control module can be a button or other switch installed on the hot work equipment. When all three indicator lights are lit, the operator can ultimately trigger the opening or closing of the hot work equipment by controlling the four-level switch control module.

[0040] In an optional embodiment, the image processing terminal specifically includes an image acquisition module, an image processing module, and an identity recognition module. Specifically, the image acquisition module receives acquisition commands from the primary switch control module and acquires the facial information of the on-site operators; the image processing module processes the operators' facial information, converting the image information into digital information; and the identity recognition module compares the processed facial information of the operators with the facial information in the online hot work application information. Specifically, when the image processing module processes the facial information, it converts the facial image into a set of feature vectors. Similarly, the facial image in the online hot work application information is also converted into a set of feature vectors. The identity recognition module compares the two sets of feature vectors to obtain the identity recognition result and further issues secondary control commands to the secondary switch control module based on the recognition result.

[0041] In an optional embodiment, the engineering hot work permission management system further includes a first display terminal installed on the hot work equipment. The first display terminal is connected to a server and is used to receive online hot work application information sent by the server. The first display terminal can be a screen installed on the hot work equipment, capable of displaying the applicant's photo and name from the online hot work application information. Thus, during random checks, the approval process can be improved by comparing the applicant's photo with the actual operator, preventing the possibility of personnel changes during hot work operations.

[0042] Alternatively, the image acquisition module at the image processing end can collect the facial information of the hot work operator in real time and compare the facial information with the facial information in the online hot work application information. When the recognition fails, the secondary switch control module sends a shutdown command to the power supply of the hot work equipment, thereby shutting down the power supply of the hot work equipment and stopping the hot work equipment from working.

[0043] In an optional embodiment, the engineering hot work permission management system further includes a monitoring terminal and a second display terminal. The monitoring terminal is used to collect on-site hot work information, and the second display terminal is used to display the on-site hot work information collected by the monitoring terminal, thereby facilitating comprehensive monitoring of the on-site hot work situation. Specifically, the monitoring terminal can be a camera installed at the hot work site, wherein the number of cameras can be one or more. The second display terminal can be one or more electronic displays to facilitate the approval personnel to monitor the on-site hot work situation at any time.

[0044] In summary, the applicant for hot work initiates an online application through the application portal. After approval by the first and second approval portals, an identity verification is triggered via a primary switch control module to ensure that the actual operator of the hot work is consistent with the applicant. During this process, the power supply to the hot work equipment is only activated after identity verification is complete and the hot work start time specified in the application has arrived, allowing the operator to perform the hot work via the four-level switch control module. This establishes a complete online application and approval process for hot work, ensuring consistency between the operator and the applicant before the hot work begins and controlling the actual hot work time to guarantee compliance. Furthermore, monitoring the hot work site through a monitoring terminal allows for better supervision of hot work safety.

[0045] Secondly, referring to Figure 2 This application also discloses a method for managing hot work permits in engineering projects, used to implement the hot work permit management system as described in the first aspect. The method for managing hot work permits specifically includes: S101. The application terminal initiates an online hot work application based on the trigger command and generates hot work application information; S102. The server receives the hot work application information and sends the first approval instruction to the first approval terminal; S103. The first approval terminal receives the approval instruction, reviews the hot work application information and the hot work site, and generates the first approval result information; S104. The server receives the first approval result information and sends the second approval instruction to the second approval terminal; S105. The second approval terminal receives the second approval instruction, reviews the hot work application information and the hot work site, and generates the second approval result information; S106. The server receives the second approval result information and sends a first-level control command to the hot work equipment switch control terminal. If the first-level control command is an opening command, the hot work equipment switch control terminal sends an image acquisition command to the image processing terminal. S107. The image processing terminal collects the facial information of the hot work operator and compares it with the online hot work application information; S108. If the operator's facial information matches the online hot work application information, and the time meets the hot work start time, the hot work equipment switch control terminal sends an opening command to the hot work equipment power supply terminal.

[0046] Specifically, in an optional embodiment, in step S101, before applying for hot work, since the server has already stored the basic information of the personnel involved in the hot work, the applicant finds their basic information on the application interface, then fills in the location and time of the hot work, and triggers the online hot work application.

[0047] In an optional embodiment, in step S107, if the operator's facial information does not match the online hot work application information, the image processing terminal sends a secondary control command to the secondary switch control module to close the application, and the hot work equipment switch control terminal sends a notification command to the server. The server receives the notification command and sends a notification to the first approval terminal and the second approval terminal. Specifically, this could involve sending a text message, making a phone call, or sending an email to the first approval terminal and the second approval terminal to alert the approvers of the risk of facial recognition failure.

[0048] In an optional embodiment, after step S108, if the operator shuts down the hot work equipment via the hot work equipment switch control terminal, the hot work equipment switch control terminal sends a notification instruction to the server. The server receives the notification instruction and sends a notification to the first approval terminal and the second approval terminal. Specifically, during the hot work operation, if the operator manually shuts down the four-level switch control module to end the hot work operation, the four-level switch control module sends a notification instruction to the server. The server receives the notification instruction and sends a telephone call, SMS message, or email to the first approval terminal and the second approval terminal to indicate that the hot work operation has ended.

[0049] The foregoing description includes examples of one or more embodiments. It is certainly impossible to describe all possible combinations of components or methods in order to describe the above embodiments, but those skilled in the art will recognize that further combinations and arrangements of the various embodiments are possible. Therefore, the embodiments described herein are intended to cover all such changes, modifications, and variations that fall within the scope of the appended claims. Furthermore, the term "comprising" as used in the specification or claims is interpreted in a manner similar to the term "including," just as "comprising" is interpreted as a conjunction in the claims. Additionally, the use of any term "or" in the specification of the claims is intended to mean "non-exclusive or."
