Example two
Fig. 2 is a flowchart of a method for remotely monitoring power generation equipment according to an embodiment of the present invention, where the present embodiment is applicable to a case where power generation equipment is remotely monitored based on a 5G transmission technology, and the method may be implemented by a system for remotely monitoring power generation equipment according to an embodiment of the present invention, as shown in fig. 2, the method specifically includes the following steps:
and S210, acquiring the operation data of the power generation equipment through the data acquisition and processing module, and preprocessing the operation data.
The operation data of the power generation equipment refers to data generated in the operation process of the power generation equipment, such as power data of voltage, current and the like, or equivalent ratio data of inlet temperature and inlet pressure.
For example, a dedicated acquisition device may be disposed in the data acquisition and processing module, and the data acquisition and processing module is connected to an acquisition point on the power generation equipment through an ethernet to acquire operation data of the power generation equipment, where the acquired operation data is generally OPC protocol data, and the OPC protocol data may be converted into Modbus protocol data to adapt to data communication of the field protocol converter.
Exemplary preprocessing of the operational data may include: and processing operations such as data null interpolation, abnormal data detection, data redundancy removal and the like.
And S220, converting the preprocessed operation data into first protocol data through a field protocol converter, wherein the first protocol data is data adapted to a 5G communication transmission protocol.
The field protocol converter is used for data format conversion.
Specifically, the field protocol converter is respectively connected with the data acquisition and processing module and the transmission module; the data processing device is used for converting the preprocessed operation data into first protocol data, and the first protocol data are data of a 5G communication transmission protocol.
Illustratively, the first protocol data is data adapted to a 5G communication transport protocol, and may be, for example, a TCP protocol. The preprocessed operation data in the Modbus protocol format is converted into a TCP communication protocol through a field protocol converter for 5G transmission.
The TCP communication Protocol, Transmission Control Protocol (TCP), is a connection-oriented, reliable transport layer communication Protocol based on a byte stream. TCP accommodates layered protocol hierarchies that support multiple network applications. Reliable communication services are provided by means of TCP between pairs of processes in host computers connected to different but interconnected computer communication networks. The application layer sends a data stream represented in 8-bit bytes to the TCP layer for internetwork transfer, and the TCP then partitions the data stream into segments of appropriate length. TCP gives each packet a sequence number in order to ensure that no packet is lost, and the sequence number also ensures in-sequence reception of packets transmitted to the receiving end entity. Then the receiving end entity sends back a corresponding acknowledgement ACK to the successfully received packet; if the sending entity does not receive an acknowledgement within a reasonable round trip delay RTT, the corresponding data packet is assumed to be lost and will be retransmitted. TCP uses a checksum function to check whether the data has errors; the checksum is calculated both at the time of transmission and at the time of reception. The TCP protocol can provide reliable communication services.
And S230, sending the first protocol data to a background protocol converter through a transmission module based on the preset frequency through a 5G transmission network.
Specifically, the transmission module supports a TCP communication protocol, and the transmission module may include a 5G field terminal, a 5G communication link, and a data processing unit. And the inside of the 5G field terminal is reasonably scheduled by the micro control unit to realize high-frequency data transmission. The data transmission process of the 5G field terminal comprises the following steps: initializing the 5G field terminal and sending data packets for 2 steps. When the method is executed, the 5G field terminal is initialized, and whether the 5G card is installed or not and the 5G signal strength are detected. After initialization is completed, card numbers, use frequency and signal strength are automatically acquired, and if the signal strength meets the preset strength requirement, operations of sending TCP, acquiring positions, acquiring time and the like are allowed to be executed. The data processing unit supports a 5GTCP communication protocol, is compatible with various encryption and decryption modes, has the capability of receiving 5G signals of all system loads, has the functions of positioning, communication, time correction, user authorization, safety management, big data processing and the like, and is used for improving the safety of data transmission. And the 5G communication link is used for providing a 5G data communication service.
S240, converting the first protocol data into second protocol data through a background protocol converter, and sending the second protocol data to a monitoring and diagnosing center, wherein the second protocol data is data adaptive to the monitoring and diagnosing center.
The background protocol converter is used for inverse conversion of data formats.
Specifically, the background protocol converter is respectively connected with the transmission module and the monitoring diagnosis center; the monitoring and diagnosing system is used for converting first protocol data into second protocol data, wherein the first protocol data is data adapted to a monitoring and diagnosing center.
The second protocol data is data adapted to the monitoring and diagnosis center, and may be, for example, an OPC data format. And the TCP communication protocol is converted into an OPC data format which can be used by the monitoring and diagnosing center through the background protocol converter, so that the information interaction between the background protocol converter and the monitoring and diagnosing center is realized.
And S250, analyzing the second protocol data through the monitoring diagnosis center, and monitoring the power generation equipment according to the analysis result.
Specifically, the monitoring and diagnosing center analyzes and analyzes the second protocol data transmitted by the background protocol converter through a special digital receiving program, and feeds back a control instruction and operation diagnosis information to the power generation equipment. The monitoring and diagnosing center is provided with a display device for displaying the operation data, the analysis result and other data of the power generation device. The display interface of the display equipment can be flexibly customized according to the display requirements of the power generation equipment sequence control, regulation control and safety protection system.
For example, the method for analyzing the second protocol data may adopt a zero-code and configuration modeling technology, provide a draggable component function under different application scenarios for the power generation equipment based on a nonlinear equation system solution technology, and realize system collaborative optimization control driven by a computing engine by building in heat balance computing, rule computing, numerical optimization and deep learning units.
