Description

Technical Field

[0001] The present invention relates to the technical field of coal conveying control, and in particular to an industrial television production process monitoring system for coal conveying control and a control method thereof. Background Art

[0002] In power plants, operators of coal conveying program control systems mainly operate on the operating table in the coal conveying control room, and monitor the equipment movements and production processes of various parts of the coal conveying production line through industrial televisions on site. The current industrial televisions use network cameras, and the video signals are connected to the video monitoring system through optical fibers, and then transmitted to the large-screen control system in front of the operating table through the network. The current large-screen control system uses a large-screen split display. Since there are many cameras monitoring the production process and the monitoring screen of the large screen is limited, the operator cannot fully grasp the operation of the current production process through the large screen. During production, the operator must check the production data screen on the operating table and often look up to see the video image on the large screen in front of the operating table. Operators are in this monitoring mode for a long time, which is easy to increase the fatigue of the operator. For coal conveying production, the rhythm and efficiency will also be affected.

[0003] By observing the operators' work process, it was found that the industrial TV images that operators pay attention to in different production processes are related to the equipment used in production. For the coal transportation process, the operators are concerned about the operation of the belt that is transporting coal. When encountering an instruction to replace the coal conveying bunker, the operator needs to switch the monitoring to the belt that is ready to start. For abnormal situations that occur during the production process, the operator needs to manually switch the video image and control the camera to rotate to the fault position. This requires the operator to have high requirements for the location of the on-site equipment.

[0004] To address the above issues, currently large-screen systems are used to display industrial video surveillance on site. When an alarm is encountered, operators need to manually switch and adjust the camera position. For mobile monitoring equipment such as inspection robots, operators need to manually control the inspection robots to move to a specified position and adjust the camera position. This operation method will affect operators' attention to the production process and affect production safety and efficiency.

[0005] Therefore, there is a need in the market for an industrial television production process monitoring system for coal transportation control and a control method thereof that can improve monitoring efficiency and emergency response capabilities. Summary of the invention

It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0062] According to the present invention, an industrial television production process monitoring system for coal transportation control is provided, such as Figure 1 As shown, it includes: display layer, application layer, access layer and device layer. The device layer includes cameras, PLC devices, and inspection robots; the access layer includes data acquisition modules, device control services, and video access services; the application layer includes data processing services, intelligent linkage modules, configuration processing services, and video management services; the display layer includes configuration display services, such as Figure 5As shown, the device layer is used to provide equipment to monitor the production process of coal transportation and generate control instruction information to the application layer. The access layer is used to collect the data information provided by the device layer and parse the data information into structured data set inside the program, and send the structured data set inside the program and the industrial video of the device layer to the application layer. The application layer sends the control instruction information to the access layer, and the access layer converts the control instruction information into a PLC control packet through a specific interface protocol and sends it to the device layer for response. The application layer generates linkage rules and linkage plans, and after analysis and processing, it links with the access layer to generate a video stream address and provides it to the display layer for display.

[0063] The equipment layer includes cameras, PLC devices, and inspection robots. Among them, the camera, as a video acquisition device for industrial television, is deployed in the production area of ​​the coal transportation production process to monitor the coal transportation production process. The PLC device, as a production signal access node for the production process, provides a docking protocol to the outside world, and the external system can collect and control the signals of the production equipment through the protocol. The inspection robot, as a machine inspection device, is installed above each coal conveyor belt. The inspection robot has one-dimensional mobility and video monitoring capabilities. The operator can operate the inspection robot to move above the entire belt and monitor the belt through the pan-tilt camera installed on the robot.

The data acquisition module includes an acquisition interface and a data transmission interface that can collect PLC device data. Among them, the acquisition interface is used to establish network communication with the PLC device, and request data from the PLC device through a specific interface protocol, receive the reply data of the PLC device, and parse it into the structure data set inside the program. The data transmission interface is used to transmit the structure data set inside the program to the data processing service. The device control service includes a data receiving interface and a control interface that can control the data of the PLC device. Among them, the data receiving interface is used to receive the control instruction information transmitted by the data processing service. The control interface is used to establish network communication with the PLC device, and convert the control instruction information into a PLC control packet through a specific interface protocol, send the control packet data to the PLC device, and receive the control reply data of the PLC device. The video access service includes a video communication module and a streaming media forwarding module for accessing the camera. Among them, the video communication module is used to establish network communication with the camera, receive the device data reported by the camera through the GB28181 protocol, and transmit the camera information to the video management service. The video communication module can also receive device control instructions transmitted by the video management service, convert the instructions into control instructions of the GB28181 protocol, and send them to the camera to control the camera to perform corresponding control. Specifically, the control instruction content, instruction conversion and instruction sending are described as follows:

[0065] 1. Control content:

[0066] The control instructions for the camera include pan / tilt control, preset position control, and focus control.

[0067] 2. Command escape:

[0068] The communication instructions between the video communication module and the video management service are in a custom JSON format, and the content includes the instruction type, target camera ID, specific control parameters, etc.

[0069] The communication instructions between the video communication module and the camera are the standard protocol of the GB28181 protocol. The video communication module needs to parse the custom JSON format, where the target camera ID corresponds to the target camera connection for the instruction, and the instruction type and specific control parameters are converted into the control instructions of the GB28181 protocol. The conversion process includes converting the custom JSON format content into the message body of the GB28181 protocol in XML format, and adding the necessary protocol header information, so as to form a complete, correct and protocol-compliant GB28181 protocol.

[0070] 3. Instructions issued:

[0071] The video communication module sends the escaped GB28181 protocol control command to the target camera through the network connection according to the network connection rules specified in the GB28181 protocol. After receiving the control command of the GB28181 protocol, the target camera will parse it and perform the corresponding operation according to the content of the command. For example, if the command is a preset position control, the camera will rotate the lens to the specified position according to the preset position number in the command.

[0072] The streaming media forwarding module is used to receive the video stream data from the camera and output the video stream image to the configuration display service module.

[0073] The application layer includes data processing services, intelligent linkage modules, configuration processing services, and video management services.

[0074] The data processing service includes a data proxy module and a data storage module. The data proxy module is used to receive the device control instructions transmitted by each service and transmit them to the device control service. The data storage module is used to receive the data from the data acquisition module and cache and store the data.

[0075] The intelligent linkage module includes a linkage configuration module, a rule analysis module and a linkage plan disposal module. Among them, the linkage configuration module is used for users to configure and generate linkage rules and linkage plans; the rule analysis module is used to obtain data from the storage of the data processing service and make judgments based on the configured linkage rules. When the linkage rules after analysis meet the conditions, the rule analysis module transmits the linkage signal to the linkage plan disposal module; the linkage plan disposal module is used to receive the linkage signal transmitted by the rule analysis module, and obtain the linkage plan through the linkage signal, and execute the work in the linkage plan, such as transmitting the video signal that needs to be switched to the configuration processing service, and transmitting the inspection robot instructions that need to be controlled to the equipment control service. The linkage rule is a rule condition for judging whether linkage is needed. For example, in the full warehouse switching step, the linkage rule refers to the rule for judging whether the full warehouse signal meets the conditions. The linkage plan refers to the operation that needs to be performed, such as the action of switching the camera image displayed in the configuration page.

[0076] The configuration processing service is used to receive the video signal data of the linkage plan disposal module and pass the video signal data to the video management service. The configuration processing service obtains the data of the production process data points from the data processing service according to the production process data points configured on the current configuration page, and converts it into production process data that can be displayed by the configuration display service.

[0077] The video management service includes a video stream generation module and a video control module. The video stream generation module receives the signal of the configuration processing service, generates a video stream address from the video access module, and provides it to the configuration display service; the video control module receives the signal of the linkage plan disposal service, and performs video control on the video access module.

[0078] The display layer includes a configuration display service module, which includes a data display module and a video display module. The data display module is used to read the production process data of the configuration processing module and display the read data on the configuration interface; the video display module is used to access the video stream address in the video management service and display the acquired video screen on the configuration page.

[0079] The present invention aims to solve the problems of incomplete monitoring, information islands and slow emergency response in the existing thermal power fuel production process.

[0080] A control method for an industrial television production process monitoring system for coal transportation control provided by the present invention includes: a video picture acquisition step, a full-bin switching control step, a fault handling control step and a full-bin switching belt inspection robot control step.

[0081] Video screen acquisition step: The access layer acquires the currently running PLC device signal, and sends the generation process data corresponding to the PLC device signal to the application layer. The display layer acquires the generation process data and accesses the corresponding video stream address to display the acquired video screen.

[0082] Full bin switching control steps: determine whether the full bin signal is obtained. If not, the display layer displays the current video screen; if so, the application layer calculates the number of the replaced coal bin and the number of the belt that needs to be used to transport coal, and outputs the video screen number to be switched to the display layer for video page display.

[0083] Furthermore, if Figure 2 As shown, the full warehouse switching control of the present invention is specifically described as follows: First, the data acquisition module obtains the signal of the currently running PLC device and transmits the information to the data processing service. The configuration display service obtains the production process data and displays the read data on the configuration interface. The configuration process service transmits the video signal corresponding to the currently running belt conveyor to the video management service. The video management service provides the video stream address to the configuration display service. The configuration display service accesses the video stream address and displays the obtained video screen on the configuration page. When there is no warehouse change operation, the configuration display service keeps the current page unchanged.

[0084] Then, the intelligent linkage module reads the production data information of the data processing module to determine whether the full warehouse signal is triggered. If the full warehouse signal appears, the system needs to prepare for the warehouse change operation. At this time, the linkage module passes the camera number corresponding to the coal bunker information that needs to be switched to the configuration processing service. The configuration processing service will call the video management service, obtain the video stream address, access the video stream address, and switch the display of the camera video image in the configuration display service.

[0085] Fault handling control steps: determine whether a fault signal is currently triggered. If not, the display layer displays the current video screen; if so, the application layer checks the video screen number and PTZ control instructions corresponding to the fault signal, controls the production site camera to rotate to the instruction position according to the PTZ control instructions, and outputs the video screen number to be switched to the display layer for display according to the video screen number. Specifically, the intelligent linkage service of the application layer determines whether there is a PTZ control instruction. If so, the video management service of the application layer receives the PTZ control instruction and sends it to the video access service of the access layer to control the production site camera to rotate to the instruction position. At the same time, the intelligent linkage service of the application layer outputs the current video screen number to be switched, and the configuration processing service of the display layer requests the video screen number, and sends it to the video management service of the application layer to obtain the screen information and then display the screen information.

[0086] Furthermore, if Figure 3 As shown, the fault handling control of the present invention is specifically described as follows: First, the data acquisition module obtains the signal of the currently running PLC device and transmits the information to the data processing service. The configuration display service obtains the production process data and displays the read data on the configuration interface. The configuration process service transmits the video signal corresponding to the currently running belt conveyor to the video management service. The video management service provides the video stream address to the configuration display service. The configuration display service accesses the video stream address and displays the obtained video screen on the configuration page. When no fault operation occurs, the configuration display service keeps the current page unchanged.

[0087] Then, the intelligent linkage module reads the production data information of the data processing module to determine whether a fault signal is currently triggered. If a fault signal occurs, the intelligent linkage module will send the fault information to the configuration display page to remind the user. At this time, the user can view the video image of the fault signal point. After clicking to view, the intelligent linkage module will execute the linkage plan and pass the image number and PTZ control parameters of the fault point to the configuration processing service and video management service respectively. The configuration processing service will call the video management service, obtain the video stream address, access the video stream address, and switch to display the camera video image in the configuration display service; the video management service passes the PTZ control instruction to the video access service, thereby controlling the camera to rotate according to the PTZ control instruction and view the device data at the fault location.

[0088] Control steps of the patrol robot when switching to a full warehouse: determine whether the full warehouse signal is triggered. If not, the display layer displays the current video screen; if so, the application layer passes the corresponding camera number of the coal warehouse information that needs to be switched to the display layer to obtain the video stream address and access the video stream address for display. At the same time, the application layer outputs the patrol robot that currently needs to execute the patrol instruction, and controls the patrol robot to inspect the transport belt according to the patrol instruction.

[0089] Specifically, Figure 4 As shown, the control steps of the full warehouse switching belt inspection robot of the present invention are specifically described as follows: First, the data acquisition module obtains the signal of the currently running PLC device and transmits the information to the data processing service. The configuration display service obtains the production process data and displays the read data on the configuration interface. The configuration process service transmits the video signal corresponding to the currently running belt conveyor to the video management service. The video management service provides the video stream address to the configuration display service. The configuration display service accesses the video stream address and displays the obtained video screen on the configuration page. When there is no warehouse change operation, the configuration display service keeps the current page unchanged.

[0090] Then, the intelligent linkage module reads the production data information of the data processing module to determine whether the full warehouse signal is currently triggered. If the full warehouse signal appears, the system needs to prepare for the warehouse change operation. At this time, the intelligent linkage module passes the camera number corresponding to the coal bunker information that needs to be switched to the configuration processing service. The configuration processing service will call the video management service, obtain the video stream address, and access the video stream address, and switch the display of the camera video image in the configuration display service. At the same time, the intelligent linkage module obtains the inspection robot that needs to execute the inspection instruction according to the belt conveyor number corresponding to the coal bunker information that needs to be switched. The instruction is sent to the inspection robot through the data processing module and the equipment control module. The inspection robot performs the inspection mode, and the video screen of the inspection robot is displayed in the configuration display service. After the inspection is completed, if there is an abnormal situation, it will be reminded to the configuration display service.
