Detailed Description
Further details are provided below with reference to the specific embodiments.
The invention provides a three-dimensional data coupling driving method for a severe accident condition in a nuclear emergency state, which comprises the following steps:
step 1: and reading the data of the severe accident simulator. And deploying a severe accident working condition data reading program in the running environment of the severe accident simulator, persisting the data of the shared memory in the severe accident simulator into disk files, wherein the persistence frequency is 500ms, and generating 10 disk files by default.
In the running environment of the nuclear power plant severe accident simulator, a special severe accident condition data reading program is deployed. For example, the program is written in the c# language and has highly optimized algorithms to achieve low latency and high performance.
The reader processes mainly data in key-value pair format, for example: { "Temperature": "350", "Pressure": "2000" }, etc. These key values are stored in the shared memory of the simulator as data is.
The read program not only reads the data from the shared memory, but also persists it as a disk file. These data files are stored in the hard disk. Data persistence occurs every 500ms and by default generates a data file for the last 10 acquisition cycles.
To reduce the response time of the system and increase the data processing capacity, data reading programs employ techniques such as multithreading and asynchronous I/O.
Step 2: and writing the disk file into a cache database. And (3) deploying a communication program in the running environment of the severe accident simulator, analyzing the latest disk file generated by the shared memory, and writing the analyzed severe accident condition data into a Redis database (a cache database) through communication between a nuclear power plant training center and an emergency command center, wherein the warehousing frequency is 200ms. And writing the unit operation data acquired by the emergency management comprehensive platform into a Redis database through a unit operation data writing program, wherein the warehousing frequency is 200ms.

In the running environment of the severe accident simulator, a communication program is deployed, the program is written by java, and data transmission is carried out by utilizing an excellent network library of the program. The communication program firstly needs to analyze the key value pair data in the disk data file, and then carries out necessary data cleaning and format conversion.
The parsed and cleaned data is transmitted to the emergency command center via the TLS/SSL encrypted private communication network. The communication program then calls the Redis database API to write data at a frequency of 200ms.
The unit operation data writing program is an independent Java application program and is used for processing the collected unit operation data on the emergency management comprehensive platform. The data format is also key value pairs, for example: "PumpStatus: running".

And the WebSocket performs data interaction with the back-end server so as to update the three-dimensional model of the unit in real time.
Because the WebGL and the high-performance front-end technology are used, the system can update data and render a three-dimensional model of the unit under high frequency, and real-time performance is ensured.
In order to enhance the reliability of data, all data transmission of the front end and the back end adopts an encryption and verification mechanism so as to prevent data tampering or information leakage.
Because of the B/S architecture, a user does not need to install any client software, only needs to log in to the emergency management comprehensive platform through a browser, and then selects a corresponding unit three-dimensional model for viewing and operation according to the authority and the requirements.
Preferably, the emergency management integration platform is configured to support simultaneous online viewing and manipulation of the three-dimensional model by multiple users.
