With the organic combination of wireless communication systems, terminals, and sensors with independent intellectual property rights, Datang Telecom extends the “Internet of Things” application to the nuclear power field, and uses the “McWiLL Wireless Broadband Communication + Internet of Things” solution to participate in the nuclear power industry application and monitor nuclear power plants. , Control, management, communication and other systems form a “smart” network, which greatly reduces the harm of nuclear materials to the staff in the intermediate links and the errors caused by human factors. It is very important to solve the current shortcomings of the industry. improve.
This concept of Datang Telecom is unique in the industry, forming an IoT application solution for the nuclear power industry, which fully embodies Datang Telecom’s vigorous promotion of the “Internet of Things” application, and further embodies the profound concept of “Information Technology Makes Life Better”.
system structure
Datang Telecom’s nuclear power Internet of Things solution is a concentrated application of independent intellectual property technology. The system has a three-layer architecture: mobile terminals, wireless video sensors throughout the factory, various embedded sensors for industrial monitoring, and power sensors for power transmission and transformation constitute the perception layer of the network; the McWiLL wireless broadband communication network constitutes the convergence layer; The data center, dispatch center, and command center constitute the application layer. As shown in Figure 1.
The perception layer makes extensive use of Datang Telecom’s RFID chip and MEMS sensor technology; the convergence layer uses the McWiLL wireless broadband access system that can transmit data at high speed; the application layer uses Datang Telecom’s self-developed software, such as personnel positioning and patrols. System, centralized monitoring system, power management system, spatial GIS database, enterprise scene full information management and other software systems.
Performance
•McWiLL wireless broadband communication system
McWiLL (Multi-carrier Wireless information Local Loop) is a broadband wireless access technology independently developed by Datang Telecom. McWiLL has made bold innovations on the basis of the SCDMA technology system, proposed the CS-OFDMA wireless access multiple access method, and further developed the smart antenna enhancement technology. The McWiLL system has realized a mobile broadband wireless access system with efficient convergence of broadband and narrowband services in consideration of factors such as system capacity, coverage area, and networking mode, as shown in Figure 2.
The system has a flexible and fast networking; has a nationally authorized frequency band; supports high-speed mobile broadband data services and various forms of data terminals and modules; data collection and video monitoring can be performed by wireless transmission; support high-capacity concurrent voice and voice users Scheduling. It has changed the embarrassing situation of the backward data communication technology of nuclear power plants, complicated and expensive networking, and the inefficient integration of voice and broadband, and will bring about a new revolution in communication technology in my country’s nuclear power industry.
•Personnel positioning and electronic patrol
The mobile phone has built-in personnel positioning and patrol modules. Through the application layer software, the key areas of the nuclear power plant or the trajectories of key personnel can be monitored, as shown in Figure 3.
