The goal of the infrared online monitoring system is to monitor the flow of the valve hall. The whole valve hall is divided into four areas: extremely low I, extremely low II, extremely high I and extremely high II. There are 6 flow changers in each area, a total of 24 flow changers.

The infrared on-line monitoring system is distributed in 4 areas, with 7 monitoring devices laid in each area, a total of 28 monitoring devices. Through the high-precision pan tilt and rail car control system, the monitoring of all converter flow can be realized.

Infrared application

1. Composition of infrared online monitoring system

The infrared online monitoring system mainly consists of:

"Field monitoring equipment"

"Communication network"

"Infrared monitoring platform"

"Infrared online monitoring system client" consists of four parts.

2. On site monitoring equipment

The on-site monitoring equipment is the eye of the whole system,

Equipped with temperature measuring infrared thermal imager and high-definition visible light,

Equipped with high-precision PTZ and railcar control system,

The valve hall can be fully covered without dead angle.

3. Infrared online monitoring system client

The client of the infrared online monitoring system is composed of system menu, equipment layout, equipment list, real-time temperature, temperature measurement record, high temperature alarm, cruise status, shortcut menu and other modules, which visually displays the current operation status of the whole system, including valve hall information, equipment information, temperature measurement information, alarm information, cruise information, etc.

Case analysis

Technical advantages

1. Fully distributed network management, full network digital monitoring

It can be compatible with other monitoring systems, such as the real-time collection of environmental information such as temperature, humidity and water immersion in the station.

2. The front-end infrared thermal imager has a high degree of integration, and the equipment can operate independently. The plug and play front-end infrared thermal imager integrates the infrared thermal imager, visible light network camera and streaming media server. There is no need to install a hard disk video recorder separately, which greatly simplifies the equipment installation and reduces the failure points.
3. Powerful temperature analysis function

The temperature measurement shall be corrected according to the ambient temperature, the emissivity of the object and the distance to ensure the accuracy of the temperature measurement.

4. Cruise control

The system has the function of automatic cruise, and can capture or record pictures for each cruise position. Conduct temperature analysis at the cruise position. If there is abnormal temperature, the equipment will actively alarm and notify the monitoring client.

5. Equipment alarm

When the detected target object exceeds the set threshold, send temperature alarm information to the client. When the equipment has various faults or network faults, corresponding alarms will also be generated to facilitate the positioning of the problem.

Applicable Machine

Ubiquitous power Internet of things

The ubiquitous power Internet of things is to focus on all links of the power system, make full use of modern information technology and advanced communication technology such as mobile Internet and artificial intelligence, and realize the interconnection of everything and human-computer interaction in all links of the power system. It is an intelligent service system with the characteristics of comprehensive state perception, efficient information processing, convenient and flexible application, including four layers of structure: perception layer, network layer, platform layer, and application layer.

UHV Substation

As a landmark project for the large-scale application of UHV AC transmission technology in the world, 1000 kV high-voltage substations can meet more than 1/3 of Shanghai's electricity demand under full load transmission. They are super large hub substations with complete voltage levels in China.

As a pilot unit of State Grid Corporation of China for the construction of ubiquitous power Internet of things, the operation platform developed by a domestic UHV substation has been put into trial operation recently. Wuhan huajingkang Photoelectric Technology Co., Ltd., as the designated partner of the infrared thermal imager equipment of the project, embeds the infrared thermal imaging products into the whole service system, and customizes the corresponding infrared detection schemes for different application scenarios.

Infrared IOT monitoring

For all key parts such as transformers, bushings, clamps, etc., Wuhan huajingkang Photoelectric Technology Co., Ltd. has fixed multiple on-line thermal imagers for fixed-point continuous monitoring, and added multiple ROI temperature measurement areas to meet the requirements of reliability and real-time, while ensuring accurate temperature measurement in high temperature and other harsh environments.

For the transformer bodies of multiple main transformer circuits and the voltage transformers connected with them, high-resolution 640 are arranged respectively × 480 double optical pan tilt, set preset positions for automatic inspection, covering all transformers and voltage transformers connected to them on the opposite side.

For the wind control box equipped with the main transformer, due to the many internal devices in the control cabinet, the narrow space, and the large area that needs to be monitored, each control cabinet is installed and deployed with three huajingkang photoelectric s300b infrared thermal imagers, which adopt a large field of view lens and are equipped with a visible light camera and LED lighting, covering the entire monitoring area.

Cloud platform

Hua Jingkang not only provides omni-directional thermal imager monitoring for ubiquitous power Internet of things, but also independently develops a cloud platform. The thermal imager can access the network through wireless WiFi, wired and mobile cellular methods, and summarize and transmit the data to the cloud platform for storage and management.

Cloud big data and machine learning algorithm are combined to comprehensively analyze multi-dimensional information, establish an expert system based on multivariable analysis model, and carry out intelligent fault diagnosis, aging prediction, defect warning, etc. for the operation of power system.

Using the cloud monitoring Internet of things system, the new power operation and maintenance personnel can check the equipment operation and temperature status in all substations, transmission towers, distribution rooms and other power facilities distributed within a radius of hundreds of kilometers by opening the app software on their mobile phones or intelligent terminals, and make automatic diagnosis by using advanced technical means such as big data and machine learning, which greatly reduces or eliminates the dependence on personnel and quickly finds out the location of suspected hidden dangers, Reduce troubleshooting time.

Based on its long-term technical accumulation in the power industry, combined with the advanced technologies of "big cloud mobile intelligence", Hua Jingkang has helped build the "ubiquitous power Internet of things". With widely distributed intelligent sensors as the data basis, network system as the context, and data processing and intelligent algorithm on the cloud platform as the core, it comprehensively monitors the operation status of all parts of the power system, and improves the operation and maintenance efficiency of the power system, Ensure the safe and stable operation of the system.
