Why do reactors need temperature measurement? Reactor fiber optic temperature measurement system
Reactors are the main auxiliary equipment of long-distance transmission systems, playing an important role in power transmission due to their superior electrical performance. During the operation of a reactor, it is often due to external factors, internal structure, and other factors that the reactor may experience local temperature rise and overheating, ultimately leading to local burnout or even scrapping. This brings significant economic losses to the country and enterprises. Тиймээс, adopting a reactor fiber optic temperature measurement system and real-time monitoring of the internal temperature of the reactor is of great significance and practical value.

The reactor fiber optic temperature measurement adopts a fluorescent fiber optic temperature measurement device. The sensing probe of this device is made of imported quartz fiber, which has complete electrical insulation and is not affected by high voltage and strong electromagnetic fields. It is resistant to chemical corrosion and pollution, and has fast response speed, simple installation, and high temperature resistance. The backend software is used for real-time online monitoring.

Purpose of Reactor Fiber Optic Temperature Measurement System
When the reactor sends abnormal or faulty signals, the faulty area of the reactor heats up and the temperature rises. By monitoring the temperature, the operating status of the reactor can be determined, thereby achieving the goal of protecting the reactor.
Ordinary temperature measurement devices cannot measure the internal temperature of reactors. To solve this problem, our company’s developed fluorescent fiber optic temperature measurement system can solve this problem through its anti-interference and high-temperature and high-pressure resistance characteristics.

Safety Design of Fluorescent Fiber Optic Temperature Measurement System
The security of the system is crucial, therefore, in the design of the main station system, the security of the system should be fully considered to prevent unauthorized intrusion and leakage of confidential information. From the perspective of main station system security protection, the system provides security protection in both communication channels and system data.

Data security of fluorescent fiber optic temperature measurement system

Equipped with three-level security mechanisms at the operating system level, database level, and application software level.

Operating system level: Set different permission passwords on the network, non system administrators cannot operate servers and databases, and ensure system security and relative independence through routing, firewall, and other settings.
Database level: Set up demanders with different permissions and corresponding passwords in the database to ensure that unauthorized demanders cannot use data, and different demanders cannot use data beyond their level.
Application software level: Provides strict user login verification, permission control, and comprehensive management of event logs and operation records. System permission control includes functional permission control and data access permission control.

Function permission control:

The functional permission control system manages permissions from three dimensions: control objects, object operations, and operators. Based on this, it provides authorization methods for control object groups, operation groups, and operator roles. The accuracy of permission control can be determined to specific control objects and operators. The system determines the operation permissions of the login personnel based on these three dimensions.

The control objects of the system include system level nodes, terminal devices, гэх мэт. Each control object has corresponding operations, and each authorization includes three parts: a control object group, an operation or operation group, and an operator role. In order to simplify and facilitate permission management, the system provides control object group permission inheritance.
The system provides a hierarchical authorization mechanism, which enables the system to have the ability of distributed permission management and solves the problem of overly complex permission management.

Data access permissions:

The data access permission control mechanism adopts the security audit mechanism provided by the database, providing data access user control, and providing log auditing for all data operations.

The original database only has query functionality, and the applications used only operate on the application database to ensure data security.
The system can store electricity consumption data with time markers and various analytical application calculation data, with a storage time of more than 2 жил. Үүнээс гадна, the system has a powerful backup subsystem.
Detailed operation log records are available for all manual intervention data. The system design ensures high fault tolerance, and the database has three levels of data validation: field level, record level, and database level, ensuring the storage of illegal data.
