Ali region, in the eyes of many peopleThe 'Hidden West Secret Realm', but the average altitude of over 4500 meters is daunting. Ali Kunsha Airport is located in Kunsha Township, in the Ge'erzangbu (Shiquan River) valley area at an altitude of 4274 meters. It is a 4D level Chinese plateau airport. On July 1, 2010, Ali Kunsha Airport officially opened, with a 4500 meter runway building the "golden bridge" for Ali to communicate with the world.

This year marks the beginning of navigationIn 10 years, this' golden bridge in the sky 'has paved a' road to happiness'. Navigation has brought Alibaba a social progress line, transportation guarantee line, air lifeline, and national unity line, playing a key role in promoting Alibaba's economic development and assisting in poverty alleviation.

2Network communication layer

A network is composed of various communication devices and communication media to achieve information exchange between the system management layer and the on-site measurement and control layer devices.

3On site measurement and control layer

Composed of various intelligent instruments and devices installed on site, it achieves functions such as measurement, monitoring, communication, and control.

System functions

System operation monitoring

Support power transformation and distribution system— Secondary display mode, real-time collection and display of electrical parameters such as current, voltage, power, and power factor of high and low voltage circuits. Equipped with various display colors to distinguish the opening and closing status display and provide sound and light alarm prompts.

Remote control and parameter setting

Remote control of circuit opening and closing, protection on/off settings, and adjustment of alarm protection parameters can be achieved; And conduct event analysis and fault recording data analysis on alarm or trip circuits, identify the causes of alarms or trips, provide various alarm and fault displays for operators, and prompt potential fault hazard reports for the system, providing effective guarantees for the safe operation of the system.

Trend curve analysis

The trend curve system can continuously monitor the operating parameters of equipment in real time, such as power load and waveform capture at the moment of fault occurrence, helping users dynamically analyze the historical changes of various data, and providing strong data basis for management personnel to predict the parameter changes and future trends of the power supply system during a certain period of time.

Event sequence recording and querying

Real time monitoring of various status event information such as alarm status, trip status, and switch displacement status of each circuit, issuing obvious sound and light alarms for alarm and trip monitoring events, and recording all events that occur in the system to provide data support for operators to conduct detailed analysis.

Graphic Management Analysis

The system can generate various dynamic image systems for operation statistics, such as voltage bar charts, pie charts, and phase angle charts, which can graphically analyze real-time changes in various power grid parameters (such as unbalance, phase angle, etc.); And it can set alarm and trip limits for sensitive power parameters that affect the normal operation of the system load, issue alarms in advance or automatically send trip output control to ensure the reliability of the system.

Real time data reporting system

The real-time reporting system provides a unified table mode for real-time display of data and status in the running system, which can dynamically compare and monitor various circuits in real time. Real time reporting supportsExport data in EXCEL format for easy secondary processing.

Historical data report query

The historical report system can provide various types of historical data report queries, such as daily reports, quarterly reports, monthly reports, annual reports, etc. It can query various historical data such as current, voltage, power load, and energy measurement, generate various statistical data, and provide data support for user measurement statistics, internal consumption analysis, and other needs.

Third party device access

The system supports various communication protocols such as serial ports and Ethernet buses, and can perform low-level development and design for non-standard protocols to facilitate device access and integration, such as microcomputer protection devices from various manufacturers, DC screen controllers, transformer temperature controllers, intelligent analog screens, etc., achieving centralized and unified monitoring.

system interconnection

Provide standards for other types of automation systemsOPC interface or standard protocol forwarding function, realizing various data uploading and sharing, providing a unified scheduling interface for the higher-level scheduling system.
