[0022] Figure 2 A schematic diagram of a structure of an embodiment of a communication system based on a telecontrol device and a protocol conversion device provided by the present invention, as shown in FIG. Figure 2 As shown, the communication system based on telecontrol equipment and protocol conversion equipment includes: CEMS, DCS, protocol conversion equipment and telecontrol equipment; The CEMS is used to monitor gas emission data in real time and determine real-time analysis data; The DCS is used to read the real-time analysis data; the DCS includes a communication station; the communication station is installed with an OPC Server; The protocol conversion device is connected to the OPC Server and is used to perform protocol conversion on the real-time analysis data to obtain target data; The OPC Server is used to send the target data to the ground control through the telecontrol device via the IEC104 protocol; The ground modulation sends the target data to the central modulation.

[0023] The Continuous Emission Monitoring System (CEMS) is an online monitoring device for exhaust gases, which can monitor gas emission data in real time. For example, it can continuously extract the exhaust gas emitted by the enterprise for real-time analysis to obtain real-time analysis data. The real-time analysis data includes hourly averages and daily averages, which are displayed and uploaded.

[0024] CEMS can transmit real-time analysis data to a distributed centralized control system (DCS) through hard wiring or communication. A DCS includes a communication station, which can be an operating computer with OPC server or other communication software installed, specifically used to communicate with other external systems.

[0025] OPCserver (OLE for Process Control Server) is a data acquisition and communication software attached to DCS software. It can call data in the DCS database and exchange data with other external systems using a specific communication protocol.

[0026] OPC Server is a software application used to realize device data collection, integration and communication. Through standardized interfaces and protocols, it connects devices of different types and manufacturers, converts their data into a unified format, and enables various devices to easily exchange data with monitoring systems, data processing systems, etc. The main functions of OPC Server include device data collection, data format conversion, data storage and caching, and data transmission and integration. Through these functions, OPC Server can achieve seamless connection and data sharing between devices, improve production efficiency and product quality, and reduce the cost of system integration and maintenance.

[0027] A protocol conversion device, also known as a protocol converter or protocol converter, is a device used to convert between different communication protocols. It can convert data read from one communication protocol into other protocols to exchange data with other external devices, and convert one power system protocol into another, enabling seamless communication between different devices or systems.

[0028] The protocol conversion device is connected to the OPC Server to perform protocol conversion on the real-time analysis data obtained from the CEMS to obtain target data that complies with specific communication standards or protocols.

[0029] OPC Server can use IEC104 protocol to send target data to local dispatch (regional dispatch center) through telecontrol equipment. Local dispatch is an important part of the power system, responsible for monitoring and dispatching power equipment in the region. IEC104 protocol is the communication protocol of the power system, which can ensure the reliable transmission of data.

[0030] Telecontrol equipment, also known as remote action machines or telemotors, is an IoT communication device used to remotely monitor and control remote operating equipment.

[0031] The data is sent to the local dispatching station through the one-way network gate of the telecontrol equipment, and the local dispatching station can transmit it to the central dispatching station (intermediate dispatching center) in real time after receiving it. The central dispatching station (intermediate dispatching center) is usually responsible for power dispatching and monitoring in a larger area.

[0032] Compared with the prior art, the communication system based on telecontrol equipment and protocol conversion equipment provided by the embodiment of the present invention determines the real-time analysis data by real-time monitoring of gas emission data by CEMS, the real-time analysis data is read by DCS, the protocol conversion equipment performs protocol conversion on the real-time analysis data to obtain the target data, and the target data is sent to the local control through the telecontrol equipment by the built-in OPC Server of DCS through the IEC104 protocol, and the local control further sends the target data to the central control. By integrating CEMS, DCS, protocol conversion equipment, OPC Server and telecontrol equipment, the real-time monitoring, analysis, conversion and remote transmission of gas emission data are realized. The communication effect can be achieved by utilizing the IEC104 communication script authority expanded by the built-in OPCserver of DCS and the electrical telecontrol equipment and protocol conversion equipment, which can save the cost of purchasing equipment, and at the same time, the data accuracy and stability are high.

[0033] In some embodiments of the present invention, it further includes: The ECS is used to establish a channel to capture the target data in hexadecimal format.

[0034] In some embodiments of the present invention, the ECS is further used for: Establish database and control electrical telecontrol communication screen.

[0035] The Electric Control System (ECS) software can establish a database to control the electrical telecontrol communication screen.

[0036] ECS establishes a channel to capture the hexadecimal data after the protocol conversion device converts the protocol. ECS establishes an independent environmental data upload page, which can monitor in real time whether our communication is interrupted or other communication anomalies occur, and can reflect abnormal data on the ground survey end.

[0037] For example, the ECS can establish a channel to communicate with the protocol conversion device or the telecontrol device. This channel is the basis of data transmission and ensures the real-time and accuracy of the data.

[0038] After the channel is established, the ECS system can perform hexadecimal packet capture and analysis on the transmitted data to determine the specific content of the data, whether there are errors or anomalies in the transmission process, and the communication status of the device. By capturing and analyzing hexadecimal data packets, the ECS system can gain an in-depth understanding of network communication problems and provide strong support for troubleshooting and performance optimization.

[0039] The ECS system can establish a database to store and manage data obtained from telecontrol equipment or protocol conversion equipment. These data include equipment status, operating parameters, fault records, etc., providing a basis for monitoring, analysis and optimization of the electrical system.

[0040] The ECS system is also responsible for controlling the electrical telecontrol communication screen. Through the telecontrol communication screen, users can view the operating status, parameter information, etc. of electrical equipment in real time, and realize remote monitoring and control of the electrical system.

[0041] The communication system based on telecontrol equipment and protocol conversion equipment provided in the embodiment of the present invention can not only establish a channel to capture hexadecimal data of target data through ECS, but also establish a database to control the electrical telecontrol communication screen, thereby providing strong support for the stable operation and efficient management of the power system.

[0042] In some embodiments of the present invention, the OPC Server is specifically used for: Based on the IEC104 protocol, the ground station is determined as the main station; The OPC Server acts as a slave.

[0043] OPC Server can establish IEC104 master and slave stations according to IEC104 protocol. The master and slave station addresses are defined by IP. The distinction between master and slave stations is to successfully establish communication in accordance with the characteristics of the equipment. As a slave station, OPC Server can be captured by the local end.

[0044] For example, in a communication system based on the IEC104 protocol, the ground station is the master station, responsible for initiating data requests and receiving data from the slave stations. The OPC server, as a slave station, needs to respond to the data request of the master station and provide real-time or historical data. The data communication process follows the message format and communication process of the IEC104 protocol to ensure the accuracy and reliability of the data.

[0045] OPC Server has the function of data standardization, which can convert data from different devices and manufacturers into a unified format, so as to realize data sharing and intercommunication between different systems. As the core component of data exchange, OPC Server helps to simplify system integration.

[0046] Through OPC Server, new devices or systems can be integrated into the existing industrial automation environment. At the same time, OPC Server supports multiple data types and protocols, and can be flexibly configured according to different needs, supporting system expansion and function addition.

[0047] When the local station is used as the master station, the operating status of the slave station equipment can be remotely monitored through the OPC Server and necessary control operations can be performed.

[0048] In some embodiments of the present invention, the CEMS establishes a communication connection with the DCS via a PROFIBUS-DP protocol.

[0049] DCS and CEMS establish PROFIBUS-DP communication, so that DCS can directly read the real-time analysis data of CEMS analyzer.

[0050] In some embodiments of the present invention, the protocol conversion device is connected to the OPC Server via a network cable.

[0051] The OPC server is directly connected to the protocol conversion device via a network cable, so that the protocol conversion device can perform protocol conversion on the real-time analysis data obtained from the CEMS to obtain target data that complies with specific communication standards or protocols.

[0052] In some embodiments of the present invention, the DCS further includes: Cabinets, operator stations, engineer stations and historian stations.

[0053] The cabinet is equipped with CPU controller, I / O cards, power supply and other equipment.

[0054] The operator station is the core part of the DCS system for monitoring and operation, usually equipped with a high-resolution display and keyboard. The operator uses the operator station to monitor the production process in real time, adjust parameters and handle alarms to ensure stable operation of the system.

[0055] The engineer station is mainly used to write and modify control logic programs and configure the system. It has high authority and can access and modify all functional modules of the system, supporting the implementation and maintenance of complex control strategies.

[0056] The historical station is responsible for storing and managing historical data in the production process, including historical curves, alarm records and operation logs. Through the analysis of historical data, the production process can be optimized and the reliability and efficiency of the system can be improved.

[0058] The execution subject of the data transmission method provided by the present invention may be the communication system based on the telecontrol device and the protocol conversion device described in any of the above implementation modes.

[0059] In S301, CEMS may be used to monitor gas emission data in real time. For example, waste gas emitted by an enterprise may be continuously extracted for real-time analysis to obtain real-time analysis data. The real-time analysis data may include hourly average values ​​and daily average values.

[0060] In S302, CEMS can transmit real-time analysis data to DCS through hard wiring or communication. DCS includes a communication station, which can be an operating computer installed with OPC server or other communication software, and is specially used for communicating with other external systems.

[0061] After the DCS reads the real-time analysis data, the protocol conversion device is connected to the OPC Server, so that the protocol conversion device can perform protocol conversion on the real-time analysis data to obtain target data that conforms to a specific communication standard or protocol.

[0062] In S303, the target data is sent to the ground control through the telecontrol device by using the IEC104 protocol through the OPC Server. The IEC104 protocol is a protocol used for telecontrol communication in power systems, which specifies the data format, transmission method, and communication rules.

By integrating CEMS, DCS, protocol conversion equipment, OPC Server and remote control equipment, the real-time monitoring, analysis, conversion and remote transmission of gas emission data are realized. The communication effect can be achieved by utilizing the IEC104 communication script authority extended by the built-in OPC server of the DCS and the electrical remote control equipment and protocol conversion equipment, which can save the cost of purchasing equipment, and at the same time, the data accuracy and stability are relatively high. Using the existing protocol conversion equipment and remote control equipment, a channel is opened in the ECS system to capture data and upload it to the ground control.

[0065] In addition, the communication system and data transmission method based on the telecontrol device and the protocol conversion device provided by the present invention have the following advantages: (1) The existing method collects data in the power plant safety zone I through a forward isolation device and converges it in the power plant safety zone II environmental protection application and communication system.

[0066] (2) The environmental protection application and communication system of the safety zone II of the existing method transmits data through the firewall and the scheduling data network to the environmental protection communication server, and the data communication adopts the standard 61850 protocol. However, the data of the telecontrol equipment in the present invention has been uploaded through the firewall, and the protocol conversion device is used to achieve the effect of protocol conversion, and the data is successfully uploaded.

[0067] (3) The existing data transmission method uses the method of sending a data "crawling" request from the central dispatching side communication server to each power plant communication server to obtain data. However, the present invention uses a virtual OPC server to replace the data acquisition hardware device.

[0068] (4) In the present invention, DCS, OPC, and ECS are all powered by a large UPS in the power plant.
