As shown in Figure 4 and 5, PC is on-line monitoring background host computer and system, Gateway are the network switch, and Server is Integrated application server, ProC are protocol converter/on-line monitoring intelligent cell, and HUB is hub, and Z is high performance remote Pass gas density relay.On-line monitoring system framework: detailed column simple architecture (Fig. 4), conventional architecture (Fig. 5), complicated architectures etc. System diagram.System architecture diagram and simple declaration: 1, daemon software platform: based on Windows, Linux and other etc., or VxWorks,Android,Unix,UCos,FreeRTOS,RTX,embOS,MacOS.2, daemon software key business module, base This function: such as rights management, equipment management, data are stored in inquiry；And user management, alarming and managing, real time data, Historical data, real-time curve, history curve, configuration management, data acquisition, data parsing, record condition, abnormality processing.3, boundary Face configuration: such as the interface Form, web interface, configuration interface.Monitoring system may be the architecture system of wireless transmission method Figure can be made one or fission by wireless module and high performance teletransmission gas density relay, and concrete scheme can spirit It is living.

The temperature of the inside electric appliances SF6 gas such as breaker, GIS, pressure, close can be monitored in real time in this monitoring system Physical quantitys and its variation tendencies such as degree, micro- water, and have communication interface, upload the data to background system, realize breaker, The on-line monitoring function of the physical quantitys such as the electrical equipments such as GIS SF6 gas density is, micro- water, and alarm threshold can be flexibly set, just Ground enquiry of historical data, accurate to analyze and determine equipment gas leakage trend and leak rate, there are abnormal conditions in discovering device in advance, thus Ensure the safe operation of electrical equipment and substation's whole system.Really realize the electrical of substation, especially unattended station The on-line monitoring of equipment.Expected diagnosis and trend analysis are carried out in safe operation and operation and management level to network system is improved, It reduces and plays an important role without scheduled outage maintenance.

System is monitored by the gas density that high performance teletransmission gas density relay forms, it is described several high performance remote It is wired or wireless for passing the communication mode of gas density relay.Wired communication modes are RS232, RS485, CAN-BUS etc. Industrial bus, fiber optic Ethernet, 4-20mA, Hart, IIC, SPI, Wire, coaxial cable, PLC power carrier etc.；Wireless telecommunications Mode be 5G/NB-IOT communication module (such as 5G, NB-IOT) built in sensor, 2G/3G/4G/5G, WIFI, bluetooth, Lora, Lorawan, Zigbee, infrared, ultrasonic wave, sound wave, satellite, light wave, quantum communications, sonar etc., will be on various sensing datas Pass to Internet of Things cloud platform.Wherein hub uses RS485 hub, and IEC61850 protocol converter or 104 agreements turn Parallel operation also services printer with network respectively and network data router is connect.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution The range of scheme.
