Problems solved by technology

However, there are three problems in this solution: 1. Hardware failure occurs: when the industrial computer fails, the link of the entire upper control system will be paralyzed, affecting the reliability of the overall system operation; 2. Software failure occurs: when the main industrial control system When there is a problem with the communication of the machine, the operation of the acquisition software, the delivery of the message, and the feedback message, there is no monitoring device to assist in detecting it, and it can only continue to run with the disease, which affects the reliability of the system operation; The level requirements are high, and its own operating environment is also relatively harsh, especially involving the major personal and property safety of nuclear power workers and surrounding residents, so it puts forward high requirements for its overall reliability, which further increases the difficulty of system reliability design and its cost

Abstract

The invention discloses an upper layer system for redundant radiation monitoring. The upper layer system comprises a local instrument, an RS-485 serial bus, a collection station, a main supervisor disk, an auxiliary supervisor disk, a switch and a database server; the collection station comprises a main industrial computer and a standby industrial computer. The local instrument is connected to themain industrial computer and the standby industrial computer at the same time; the main industrial computer and the standby industrial computer are respectively equipped with main serial port acquisition software and spare serial port acquisition software; and data in the main industrial computer and the standby industrial computer are transmitted to the main supervisor disk, the auxiliary supervisor disk and the database server through the switch. The invention can solve the problem of hardware and acquisition software failure of the industrial control computer at the same time, and greatlyimproves the output reliability of the system; and at the same time, a novel industrial control computer and a full set of domestic system software with better stability and functionality are used forupgrading an original system.

Description

Technical field: [0001] The invention relates to the field of redundant radiation monitoring, in particular to an upper layer system of redundant radiation monitoring. Background technique: [0002] The dumbest and most effective way to improve the stability of any system is redundant design. Theoretically speaking, the use of redundant design can make the system failure rate close to zero, but due to the need to purchase more hardware equipment, the initial investment and later maintenance costs increase, so the redundant system is generally only recommended in some special industries Use, such as financial fields, aerospace fields, nuclear safety fields, etc. Among them, the radiation monitoring system is an important part of the instrument and control system of nuclear power plants. Due to problems such as long operating life, equipment aging, and spare parts shutdown, the overall operation reliability of the system is greatly reduced. Therefore, the redundancy of the ex...
