Description

Technical Field

[0001] The present invention relates to a two-ticket operation management system based on the Internet of Things, and in particular to a two-ticket operation management system based on the Internet of Things applied in the field of operation management. Background Art

[0002] Two-ticket operation refers to the operation activities under the work ticket and operation ticket system. The two tickets include the work ticket and the operation ticket, which are important measures to ensure safety in power work. The existing two-ticket operation operations are relatively cumbersome, and the formalities alone take a lot of time, which greatly reduces work efficiency.

[0003] In order to solve the problem of cumbersome two-ticket operation procedures, a two-ticket operation management in the market adopts the design of mobile terminals, which has a certain market share.

[0004] The Chinese patent CN201410044727.X specification discloses a mobile terminal for handling power production field operations, which includes: two ticket management modules, which are used for work ticket review, remote permission issuance of work tickets, operation ticket review, and operation ticket step-by-step execution of power outage operations; an operation form module, which is used to receive electronic signatures and form contents, and transmit them back to the safety production management system; a defect management module, which is used to track and record safety defects and provide a function for viewing safety defect records, and transmit safety defects and corresponding picture attachments back to the safety production management system in real time; a graphic file module, which is used to provide power production field operators with graphic file information. The present invention enables field operators to efficiently complete all field work by carrying only a mobile terminal device instead of a large number of paper sheets and materials.

[0005] The specification of Chinese patent CN202010850581.3 discloses an electronic two-ticket system for power production operations, which includes a system background, a mobile APP, an intelligent robot system, and an intelligent safety helmet system; the system background is based on Internet of Things technology to realize open integration, basic support, data services, and basic functions of authority control. The mobile APP is based on the existing work site safety management and control system functions, and the mobile APP is connected to the intelligent robot system and the intelligent safety helmet system through a wireless data network. The intelligent robot system receives the tasks and ticket data push from the mobile APP, and controls the intelligent robot through the APP, feeds back on-site information, detects on-site personnel, takes photos, and records violation information through video, conducts safety inspections on operating personnel, and promptly discovers the implementation and execution of safety measures by personnel; the present invention has the advantages of being fast, flexible, convenient, high in operation safety, and high in operation efficiency.

[0006] Although the existing two-ticket operation management system can improve operation efficiency through mobile terminals, operators may make mistakes in reading the invoicing information, resulting in operators not walking to the corresponding electrical equipment cabinet to operate, which in turn causes safety problems. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to monitor and warn the operators who go into the wrong operation interval to ensure the safety during the operation.

[0008] To solve the above problems, the present invention provides a two-ticket operation management system based on the Internet of Things, including a management platform body, multiple parallel electrical equipment cabinets and yellow lines corresponding to the electrical equipment cabinets, the management platform body includes an invoicing system body, a front-end data acquisition layer, a data aggregation layer, a data processing layer and a third-party platform access layer, the invoicing system body includes a handheld terminal and a background invoicing platform, the front-end data acquisition layer includes multiple monitoring probes, high-definition network cameras and face recognition cameras, the data aggregation layer includes a switch, the data processing layer includes a processing server, a two-ticket equipment configuration module and a two-ticket operation management and control module, the third-party platform access layer includes an AI algorithm platform and a large-screen management center, the two-ticket equipment configuration module includes an electrical equipment cabinet information marking unit, a virtual electronic fence control unit, a two-ticket information acquisition unit and a matching unit electrically connected to the invoicing system body, the two-ticket operation management and control module includes an area intrusion monitoring unit electrically connected to the front-end data acquisition layer, a behavior recognition unit electrically connected to the AI ​​algorithm platform, a logic judgment unit and a wrong interval alarm unit, and the front-end data acquisition layer also includes a tracking and monitoring module and an operation blocking module.

[0009] In the above-mentioned two-ticket operation management system based on the Internet of Things, by drawing an electronic fence and monitoring the operation area, it is effectively prevented that the operators go to the wrong interval.

[0010] As a further improvement of the present application, the virtual electronic fence control unit deploys virtual electronic fence identification areas in front of multiple electrical equipment cabinets, and three virtual electronic fence identification areas are grouped together. There is a virtual electronic fence identification area in front of each electrical equipment cabinet, and a monitoring probe is used to monitor multiple virtual electronic fence identification areas at the same time, thereby effectively preventing operators from going into the wrong interval.

[0011] As a further improvement of the present application, multiple monitoring probes are installed above the virtual electronic fence identification area through a mounting frame, and each monitoring probe is responsible for monitoring a group of virtual electronic fence identification areas. When the operator enters the virtual electronic fence identification area, the monitoring probe monitors and identifies him. If the operator enters an uninvoiced virtual electronic fence identification area, an alarm is triggered.

[0012] As a further improvement of the present application, the tracking and monitoring module includes a slide rail, and the slide rail is located directly above a plurality of electrical equipment cabinets, a linear motor is installed on the slide rail, and the output end of the linear motor is connected to a moving seat sliding on the slide rail, a tracking camera irradiating in the direction of the yellow line is installed on the side wall of the moving seat, a laser transmitter is installed in the middle of the lower end of the moving seat, the upper side walls of the plurality of electrical equipment cabinets are fixedly connected with brackets at the same time, and the brackets are installed with laser receivers on the side walls above each electrical equipment cabinet, the laser receiver includes a verification unit electrically connected to the two ticket information acquisition units, and the verification unit is electrically connected to an early warning unit electrically connected to the operation prevention module, a downwardly inclined nozzle is fixedly connected to the lower side wall of the moving seat, and a storage box connected to the nozzle is fixedly connected to the upper end of the moving seat, liquid carbon dioxide is stored in the storage box, and an electromagnetic control valve electrically connected to the operation prevention module is installed at the liquid outlet of the storage box, when the staff just enters from the entrance, the tracking camera recognizes that the operation is being performed. The tracking camera controls the linear motor to achieve tracking movement and monitor the movements of the operators in real time. When the operators enter a virtual electronic fence identification area, the mobile seat moves to the middle of the electrical equipment cabinet here, and then the laser transmitter emits laser downward to illuminate the laser receiver. After receiving the laser, the laser receiver sends the signal to the verification unit. The verification unit compares the electrical equipment cabinet here with the equipment information on the two tickets. If the electrical equipment cabinet here is an invoiced cabinet, it means that the operator has not walked into the wrong interval. If the electrical equipment cabinet here is an uninvoiced cabinet, it means that the operator has walked into the wrong interval. Then the verification unit immediately triggers the early warning unit to alarm, and the operation prevention module is triggered at the same time. The operation prevention module starts the electromagnetic control valve on the storage box to let liquid carbon dioxide spray from the nozzle to the operators. First, it serves as a warning, and second, it uses the mist of liquid carbon dioxide to block the operator's line of sight to prevent them from performing operations.

[0013] As another improvement of the present application, a spray chamber is provided on the inner wall of the nozzle, and a plurality of equally spaced mounting grooves are provided on the side wall of the nozzle near the nozzle outlet, a spotlight is installed inside the mounting groove, and a light guide plate is fixedly connected to the opening of the mounting groove, a through opening is provided on the inner wall of the nozzle chamber opposite to the mounting groove, and a magnetic block is fixedly connected in the through opening, a flasher is slidably connected to the magnetic block toward the side wall inside the mounting groove, and the flasher is located between the spotlight and the light guide plate, a magnetic slide is slidably connected to the magnetic block toward the inner wall of the nozzle chamber, and the magnetic slide and the flasher are magnetically attracted to each other, and the magnetic slide is fixedly connected to a force-bearing member on the side wall away from the magnetic block. Blades, and elastic wires are fixedly connected between the side walls of the magnetic slide and the inner wall of the through-hole. When liquid carbon dioxide is sprayed outward, it has a blowing effect on the force-bearing blades, and the force-bearing blades drive the magnetic slide to move, and the magnetic slide drives the flasher to move through the magnetic attraction. Since the airflow is unstable when liquid carbon dioxide is sprayed outward, and the elastic wire has a rebound effect, the magnetic slide will move back and forth, so that the flasher will irregularly block the light irradiated by the spotlight to the light guide plate, achieving the effect of flashing lights, which can effectively interfere with the sight of the operators, thereby further effectively preventing the operators from performing operations.

[0014] As another improved supplement of the present application, the flasher includes a magnetic ring, the inner wall of the magnetic ring is fixedly connected to a plurality of equally spaced vertical rods, and the side walls on both sides of each vertical rod are rotatably connected to a plurality of evenly distributed shading discs, the shading discs will produce a fanning action in the process of moving back and forth, and two adjacent shading discs will block the light emitted by the spotlight in the process of opening and closing, thereby achieving the effect of flashing lights.

[0015] As another improvement of the present application, the judgment method of the logic judgment unit includes the following steps: S1. First, the electrical equipment cabinet information marking unit registers and records the function and location information of each electrical equipment cabinet, and marks each electrical equipment cabinet with a number. Then, the virtual electronic fence control unit uses the monitoring probe to draw an electronic fence in front of each electrical equipment cabinet; S2. When the staff issues the work ticket and operation ticket through the handheld terminal or the back-end ticketing platform, the two ticket information acquisition units obtain the information of the two tickets, and the matching unit matches the content of the work ticket or operation ticket with the corresponding electrical equipment cabinet, and activates the virtual electronic fence identification area in front of the electrical equipment cabinet; S3, when the operator enters the corresponding virtual electronic fence identification area from the yellow line, and the monitoring probe detects that the area where the operator is located corresponds to the virtual electronic fence identification area marked by the matching unit, the wrong interval alarm unit is not triggered, and when the monitoring probe detects that the operator is in the virtual electronic fence identification area in front of the un-invoiced cabinet, the wrong interval alarm unit is triggered to alarm, and when the operator leaves the virtual electronic fence identification area, and there are operators in other virtual electronic fence identification areas, the wrong interval alarm unit is also triggered to alarm; S4, under the premise that the operator does not leave the virtual electronic fence identification area during the operation, if there are uninvoiced operators in other virtual electronic fence identification areas for maintenance, the wrong interval alarm unit will not be triggered. In addition, if the operator leaves the virtual electronic fence identification area and no one enters other virtual electronic fence identification areas, the wrong interval alarm unit will not be triggered; S5. After the operator enters the virtual electronic fence identification area, the behavior recognition unit uses high-definition network cameras and face recognition cameras to monitor the operator's helmet wearing and falling behavior. If the operator is found not wearing a helmet, an alarm will be issued. The AI ​​algorithm platform will be used to determine the falling behavior and whether the operator has fallen due to electric shock, collision and other factors. The safety supervisor will be reminded to check the on-site situation in time and initiate emergency rescue to prevent accidents.

[0016] To summarize, monitoring probes are used to draw a virtual electronic fence in the area in front of the electrical equipment cabinet to achieve real-time monitoring of operators, effectively prevent operators from going into the wrong interval, and monitor the operators' helmet wearing and falling behavior to effectively prevent safety accidents. Tracking cameras are used to monitor operators in real time throughout the entire process, and laser transmitters are used to further determine whether operators have gone into the wrong interval, so as to achieve self-correction after false alarms of the virtual electronic fence. When operators go into the wrong interval, carbon dioxide is sprayed on them through nozzles, which can not only strengthen warnings, but also effectively prevent operators from performing incorrect operations, thereby effectively preventing personnel from operating uninvoiced equipment cabinets.
