[0028] See also Figure 1 The embodiment of the present invention provides a linkage monitoring system for a manual valve, which is applied to an industrial scene. The industrial scene is provided with a plurality of pipelines 10, and a manual valve 20 is provided at a corresponding node of each pipeline 10. The system comprises: a valve sensor 30 fixedly provided at each manual valve, and used for collecting rotation data of the corresponding manual valve; a physical parameter sensor 40, provided inside the pipeline 10, and used for collecting physical parameters inside the pipeline 10; a monitoring device 50, provided at a preset monitoring position of the industrial scene, and used for collecting a monitoring image of a monitoring area corresponding to the preset monitoring position; an interactive device 60, provided at a preset interactive position of the industrial scene, and used for providing interactive information, and interacting with on-site operators through the interactive information; a main control platform 70, which is electrically connected to the valve sensor 30, the physical parameter sensor 40, the monitoring device 50 and the interactive device 60, and used for generating linkage monitoring information and interactive information based on the rotation data, the physical parameters and the monitoring image, sending the interactive information to the interactive device 60, and displaying the linkage monitoring information.

[0029] In a possible implementation, in order to achieve effective supervision, timely response and control of each manual valve 20 in the industrial scene, a linkage monitoring system of manual valves is constructed. In this system, a valve sensor 30 is fixedly set on each manual valve 20, and the rotation data of the corresponding manual valve 20 is collected through the valve sensor 30. For example, in this embodiment, the valve sensor 30 integrates a nine-axis sensor, and the rotation data of the manual valve 20 is collected and calculated through the nine-axis sensor and the corresponding algorithm. At the same time, a physical parameter sensor 40 is set inside each pipeline 10, and the physical parameter sensor 40 includes but is not limited to physical sensors such as pressure sensors, flow meters, and thermometers. For example, the above-mentioned physical sensors are set at the connection nodes of adjacent pipelines 10, and the above-mentioned physical parameter sensors 40 collect various physical parameters in the corresponding pipeline 10 in real time.

[0030] At the same time, a monitoring device 50 is set at a preset monitoring position in the industrial scene. The monitoring device 50 is, for example, a monitoring camera, which is used to collect monitoring images of the monitoring area corresponding to the preset monitoring position. Of course, it is easy for those skilled in the art to know that monitoring videos can also be formed based on the above monitoring images. No further details are given here. The main control platform 70 is electrically connected to the valve sensor 30, the physical parameter sensor 40, and the monitoring device 50. The electrical connection is a wired connection or a wireless connection. Through the above connection method, the collected rotation data, physical parameters and monitoring images are obtained in real time, and the corresponding linkage monitoring information is generated and displayed. For example, a monitoring screen is set on the main control platform 70, and the above linkage monitoring information is displayed in real time through the monitoring screen.

[0031] In this system, the main control platform 70 is also electrically connected to the interactive device 60, which includes but is not limited to speakers, display screens, communication equipment and other devices set at preset interactive positions in industrial scenes. After the main control platform 70 generates interactive information based on the above data, it sends it to the corresponding interactive device to complete the interactive actions with the on-site operators.

[0032] In an embodiment of the present invention, a linkage monitoring system for manual valves is constructed based on the single, passive monitoring of traditional manual valve scenarios in combination with actual needs, thereby greatly improving the effectiveness of monitoring the manual valves, being able to promptly detect illegal operations on the manual valves, and display the adverse effects in an intuitive manner, while making timely interactive responses, thereby improving the safety of industrial production.

[0033] See also Figure 2 In an embodiment of the present invention, the step of generating linkage monitoring information based on the rotation data, the physical parameter and the monitoring image includes:

[0034] S511: Generate simulated flow information of materials in each pipeline based on the physical parameters;

[0035] S512: determining whether there is an illegal opening action on the manual valve based on the rotation data;

[0036] S513: If yes, determine the corresponding illegal manual valve, and generate three-dimensional motion information for the illegal manual valve based on the rotation data;

[0037] S52: generating dynamic three-dimensional information based on the three-dimensional model of each pipeline and each manual valve, the simulated flow information, and the three-dimensional action information;

[0038] S53: Generate linkage monitoring information based on the dynamic three-dimensional information and the monitoring image.

[0039] In a possible implementation, on the one hand, simulated flow information of materials in each pipeline 10 is generated based on the collected physical parameters in the pipeline 10; on the other hand, based on the rotation data of each manual valve 20, it is determined whether there is an illegal opening action for any manual valve 20. In the specific implementation process, it is possible to monitor in advance whether each manual valve 20 has an opening task. If the manual valve 20 does not have an opening task, regardless of whether the manual valve 20 can be opened, it is deemed as an illegal opening action for the manual valve 20; if the manual valve 20 has an opening task, it is determined whether it is illegally opened based on the opening order of the manual valve 20 or the locking relationship between the manual valve 20 and other manual valves 20.

[0040] In one embodiment, it is monitored that a manual valve 20 is illegally opened, so the three-dimensional action information of the illegal manual valve is immediately generated according to the rotation data. Specifically, the corresponding three-dimensional action information is generated according to the number of rotations before the operation and the number of rotations / angles currently rotated. In order to display the industrial scene more intuitively and accurately, the three-dimensional digital twin technology is used to perform a three-dimensional dynamic display of the above data acquired in real time. Specifically, the technician can pre-set the three-dimensional model of each pipeline 10 and each manual valve 20, and map the above-collected simulated flow information and three-dimensional action information to the corresponding pipeline 10 and manual valve 20, and generate the corresponding dynamic three-dimensional information, and then generate linkage monitoring information according to the above dynamic three-dimensional information and monitoring images, and display it in real time on the display screen of the main control platform 70.

[0041] In the embodiment of the present invention, by using three-dimensional digital twin technology to display various working conditions of industrial scenes in real time and accurately, it can assist management personnel to promptly discover any abnormalities, locate abnormal points in a timely manner, and take corresponding management and control measures, which greatly improves user experience and improves safety.

[0042] In the existing monitoring and management work, the supervision of the pipeline 10 and the manual valve 20 is mainly passive. Once a danger or accident occurs, it often causes great losses, which is not in line with the actual interests of the enterprise. Based on this, the enterprise hopes to be able to predict the impending safety risks in advance on the basis of real-time supervision, and take corresponding measures in time to greatly reduce the probability of danger and even avoid safety accidents.

[0043] Based on the above technical motivation, in an embodiment of the present invention, the main control platform 70 is also used to: generate material accumulation information corresponding to each manual valve 20 based on the simulated flow information; predict the material accumulation pressure of each manual valve 20 within a preset time based on the material accumulation information, and generate a predicted pressure value; determine whether there is a risk node with explosion risk based on the predicted pressure value; if so, generate an explosion countdown for the risk node based on the predicted pressure value, and generate highlight information for the risk node; and display the explosion countdown and the highlight information.

[0044] In a possible implementation, after generating the simulated flow information of the material in each pipeline 10, further generate the material accumulation information corresponding to each manual valve 20. Specifically, according to the simulated flow information, the material collection situation of each manual valve 20 is determined in real time, including but not limited to the material collection amount, the pressure information at the location of the manual valve 20, the flow information and flow velocity information at the location of the manual valve 20, etc., and then the material accumulation pressure of each manual valve 20 within a preset time is predicted to generate a predicted pressure value. The preset time is, for example, 1-5 minutes. Preferably, according to the action speed of the on-site operators and the average dangerous contact action time, considering that the on-site operators have sufficient operation time when facing the risk of explosion, the preset time can be set to 5 minutes according to experience.

[0045] Within the preset time, when it is predicted that there is an explosion risk at any time based on the predicted pressure value, the corresponding risk node is determined, and the time closest to the explosion is determined based on the predicted pressure value, and a corresponding explosion countdown is generated, and highlight information for the risk node is generated, such as including but not limited to highlighting, difference color display, magnified display and other information for the risk node, and finally the above-mentioned explosion countdown and highlight information are displayed through the main control platform 70.

[0046] In an embodiment of the present invention, based on the traditional passive abnormal action monitoring, the data collected in real time during the three-dimensional digital twin display process is used to accurately predict and monitor the dangers of industrial scenes, so as to promptly prompt managers to control risks, effectively reduce the probability of safety accidents, and meet the actual needs of enterprises.

[0047] After determining that there is a risk of explosion at a node, the main control platform 70 can immediately issue a corresponding voice or text alarm prompt, and the management personnel can immediately go to the scene to eliminate the danger. However, this method has a certain lag and cannot solve the crisis on the scene as soon as possible, which may result in missing the best rescue time, thereby causing losses to the enterprise.

[0048] To solve the above technical problems, in an embodiment of the present invention, the main control platform 70 generates interactive information, including: after determining the existence of the risk node, determining whether there is an on-site operator within the preset range of the risk node; if there is an on-site operator within the preset range of the risk node, determining the shortest action time for the on-site operator within the preset range of the risk node to perform a risk relief operation; judging whether the shortest action time is less than the explosion countdown; if so, determining the designated operator corresponding to the shortest action time, generating and sending a first work dispatch instruction for the designated operator; otherwise, generating an evacuation instruction for all on-site operators, and generating and sending a second work dispatch instruction for safety management personnel; generating interactive information based on the first work dispatch instruction or the evacuation instruction.

[0049] In a possible implementation, after determining that there is a risk node, it is immediately determined whether there is an on-site operator within the preset range of the risk node. In an embodiment of the present invention, the determination of whether there is an on-site operator within the preset range of the risk node includes: determining the nearest monitoring device that is closest to the risk node, determining the range area corresponding to the preset range around the risk node, controlling the action of the nearest monitoring device, collecting a regional image within the range area, performing human body recognition on the regional image, and determining whether there is an on-site operator within the preset range of the risk node; or: the system also includes a mobile terminal configured for each on-site operator, obtaining the real-time location information of each on-site operator through the mobile terminal, and determining whether there is an on-site operator within the preset range of the risk node based on the real-time location information.

[0050] In the first embodiment, the nearest monitoring device that is closest to the risk node is immediately determined, and then the range area corresponding to the preset range around the risk node is determined, for example, the preset range is 50m, and the range area is a circular area with the risk node as the center and a radius of 50m, and then the action of the nearest monitoring device is controlled. For example, a rotating device (rotating pan / tilt head) is provided under each monitoring device 50, and the monitoring device 50 can be rotated within a range of 360° by the rotating device. By controlling the rotation of the nearest monitoring device, the regional image within the above-mentioned range area can be collected, and human body recognition is performed on the regional image at this time to determine whether there is any human body within the range area, and any human body that exists is determined as an on-site operator.

[0051] In an actual application scenario, if multiple field operators are found in the range area, the standing position of each field operator is further identified, and the movement time of each field operator to reach the current risk node is evaluated based on their standing position. For example, the navigation path of each field operator can be generated based on their standing position, the geographical location of the risk node, and the layout information of the industrial scene, and the movement time of each navigation path can be calculated.

[0052] In the second embodiment, when each on-site operator enters the industrial scene, he or she is required to be equipped with a corresponding mobile terminal (not shown). When a risk node is found, the real-time location information of each on-site operator is immediately obtained through the mobile terminal, and based on the real-time location information, it is determined whether there is an on-site operator within the preset range of the risk node.

[0053] If there is an on-site operator within the preset range of the risk node, the shortest action time for the operator to perform the risk elimination operation is further determined. Specifically, the shortest action time is determined based on the shortest time for the operator to move to the risk node and the shortest time for the operator to perform the risk elimination operation. At this time, it is determined whether the shortest action time is less than the explosion countdown. If so, it is determined that the on-site operator has enough time to eliminate the risk, so the corresponding first dispatching instruction is immediately generated to require the operator to go to the risk node as soon as possible to eliminate the risk.

[0054] If the shortest action time is greater than or equal to the explosion countdown, it is determined that no on-site operator can eliminate the risk within a sufficient safe time, so an evacuation order is immediately generated for all on-site operators to require all on-site operators to leave the scene immediately to protect their own safety. At the same time, a second dispatching order is generated and sent to the safety manager to require the safety manager to immediately go to the scene to eliminate the risk after reasonable safety protection. After the above-mentioned first dispatching order or evacuation order is generated, it is sent as interactive information to the interactive device 60 on site. The interactive device 60 broadcasts the interactive information through one or more of sound, text, video and other information to prompt the on-site operator to respond interactively.

[0055] In an embodiment of the present invention, after monitoring the existence of explosion risks in industrial scenes, various equipment and facilities configured in the industrial scenes are further linked to form a linkage effect on on-site operators, thereby resolving the explosion risks as quickly as possible, thereby greatly reducing the probability of safety accidents, improving the efficiency of handling safety risks, protecting the property and personal safety of enterprises and operators, and meeting the actual needs of enterprises.

[0056] After illegal or irregular operations occur, on the one hand, the company should take countermeasures as soon as possible; on the other hand, the company also needs to promptly identify the corresponding responsible persons to manage and handle internal management to meet the actual needs of the company.

[0057] In an embodiment of the present invention, the main control platform 70 is also used to: determine the time of illegal operation based on the risk node and the explosion countdown; generate an illegal operation monitoring video of a preset monitoring period before and after the illegal operation time according to the monitoring image; perform face recognition on the illegal operation monitoring video to determine the person responsible for the accident.

[0058] In one possible implementation, after determining that there is a risk node and determining the explosion countdown, the explosion countdown is decomposed to determine the time of illegal operation. Specifically, the time of illegal operation is reversely deduced based on the explosion countdown and the material accumulation rate of the risk node monitored historically, and then the illegal operation monitoring video of the preset monitoring period before and after the illegal operation moment in the monitoring image is retrieved. For example, the preset monitoring period is 30 minutes. Of course, the enterprise can set it arbitrarily according to actual needs, and no further elaboration is made here. At this time, face recognition is performed on the illegal operation monitoring video to determine the person responsible for the accident who illegally operated the relevant manual valve at the time of illegal operation and caused the risk of explosion at the risk node. In the subsequent supervision process, when the explosion risk is eliminated and the actual loss caused to the enterprise is determined, corresponding control measures can be taken against the person responsible for the accident based on the actual loss, so as to safeguard the interests of the enterprise itself and improve the internal management level of the enterprise.

[0059] In actual application, the valve sensor 30 is often fixed to the manual valve 20 by bolts. However, since the valve sensor 30 may be configured outdoors or the bolts may be corroded due to long-term use, there is a risk of the valve sensor 30 being stolen or moved, which has an impact on the company.

[0060] To solve the above technical problems, please refer to Figure 3 In an embodiment of the present invention, the valve sensor 30 includes a sensor body 31 and an anti-theft cable 32, the sensor body 31 includes a first interface 313 connected to a power supply 311 and a second interface 314 connected to a voltage sampling chip 312, one end of the anti-theft cable 32 is detachably connected to the first interface 313, and the other end is detachably connected to the second interface 314; when the anti-theft cable 32 is in a connected state, it is tightly wound around the corresponding manual valve 20.

[0061] In a possible implementation, on the basis of the basic rotation data acquisition function of the valve sensor 30, a first interface 313 and a second interface 314 are further provided on the valve sensor 30, and the first interface 313 and the second interface 314 are detachably connected to each other through an anti-theft cable 32, thereby forming a voltage acquisition closed loop. The anti-theft cable 32 has a fixed resistance value. In this embodiment, a sampling resistor is provided between the anti-theft cable 32 and the voltage sampling chip 312. When the anti-theft cable 32 is not connected to the sensor body 31, the voltage sampling chip 312 collects the first voltage through the sampling resistor of the internal circuit. At this time, it can be determined that the anti-theft cable 32 is not connected to the sensor body 31. When the anti-theft cable 32 is connected to the sensor body 31, the voltage sampling chip 312 collects the second voltage through the external circuit, thereby determining that the anti-theft cable 32 is connected to the sensor body 31. When the anti-theft cable 32 is connected to the sensor body 31, the anti-theft cable 32 is tightly wound around the corresponding manual valve. At this time, once the valve sensor 30 is illegally moved, the voltage collected by the voltage sampling chip 312 will inevitably change, thereby enabling timely response and taking corresponding anti-theft measures, thereby realizing the anti-theft function.

[0062] Specifically, in an embodiment of the present invention, the sensor body 31 is also used to: determine whether the anti-theft cable 32 is in a connected state with the sensor body 31; in response to an instruction to enter an anti-theft mode, read the voltage value through the voltage sampling chip 312; determine whether the voltage value changes; if so, generate and output corresponding alarm information.

[0063] In a possible implementation, after the technician has connected the anti-theft cable 32 to the sensor body 31, he can send a command to the valve sensor 30 through the APP or the main control platform 70 to control it to enter the anti-theft mode. At this time, once any change occurs in the connection state between the anti-theft cable 32 and the sensor body 31, including but not limited to disconnection, length change, or parallel connection with the same length to replace the thin and soft cable, the voltage value collected by the voltage sampling chip 312 will change, thereby immediately discovering the theft phenomenon and immediately outputting the corresponding alarm information.

[0064] Furthermore, in an embodiment of the present invention, the main control platform 70 is also used to: in response to the alarm information, obtain an abnormal monitoring image corresponding to the alarm information from the monitoring device 50; perform face recognition on the abnormal monitoring image to generate a face recognition result; establish a binding relationship among the alarm information, the abnormal monitoring image and the face recognition result, and store the alarm information, the abnormal monitoring image and the face recognition result.

[0065] In one possible implementation, when the main control platform 70 monitors any alarm information, it immediately links the monitoring device 50 to obtain the abnormal monitoring image corresponding to the alarm information, and performs face recognition on it. For example, a conventional target recognition algorithm or face recognition algorithm can be used to perform face recognition and generate corresponding face recognition results. Then, a binding relationship between the above alarm information, abnormal monitoring image and face recognition result is established, and it is stored in the main control platform 70. In the subsequent rapid positioning, search and tracing of responsibility work, the relevant personnel can be immediately identified and corresponding measures can be taken.

[0066] In the embodiment of the present invention, by configuring the valve sensor 30 with an anti-theft function and performing full-scene linkage monitoring with the main control platform 70, the theft behavior against the valve sensor 30 can be discovered in time and the corresponding illegal personnel can be immediately identified, which provides strong support for subsequent accountability control and meets the actual supervision needs of the enterprise.
