Problems solved by technology

[0003] For a long time, because the on-site equipment is in operation, the maintenance personnel cannot have a deep understanding of the system, so the independent maintenance ability of the system is low, and the difficult problems that have existed in the on-site fire alarm system for a long time cannot be fundamentally solved
For some urgent and complicated faults that occur on site, maintenance personnel sometimes cannot quickly locate the fault point, and cannot complete the fault treatment in time
Various inter-panel and probes cannot be tested before they are replaced on site, and the stability of new spare parts and probes cannot be well grasped

Abstract

The invention relates to a nuclear power plant offline fire alarm detection system. The system comprises a power supply conversion module, a charging card, a storage battery, on-site detection equipment, a loop card, a main controller, an operation panel and a gateway. An alternating current input terminal of the power supply conversion module is connected to an alternating current power supply line, and a direct current output terminal is electrically connected to an input terminal of the charging card. An output terminal of the charging card is connected to the loop card, the main controller, the operation panel and the gateway. An input and output switch terminal of the charging card is connected to the storage battery. The on-site detection equipment is successively connected to the loop card, the main controller, the operation panel and the gateway in a communication mode. The loop card is connected to the on-site detection equipment in a power supply mode. The system can be used for processing a complex fault generated in a nuclear power plant operation environment site, a fault reason can be rapidly found out, a fault problem is solved high-efficiently and a risk is controlled properly.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant fire alarm systems, and in particular relates to an off-line fire alarm detection system for nuclear power plants. Background technique [0002] Siemens fire alarm S1131 system is widely used in some nuclear power plant bases, especially the fire detection systems of some nuclear power plants basically adopt Siemens fire alarm 1131 system. [0003] For a long time, due to the operation of the on-site equipment, the maintenance personnel cannot have a deep understanding of the system, so the independent maintenance ability of the system is low, and the long-standing difficult problems of the on-site fire alarm system cannot be fundamentally solved. For some urgent and complicated faults that occur on site, maintenance personnel sometimes cannot quickly locate the fault point and complete the fault treatment in time. Various inter-panels and probes cannot be tested before they are repla...
