Problems solved by technology

A large fire alarm system needs to use a lot of data acquisition modules, and the data acquisition module is centralized power supply, and the communication line of the external interface is inevitably poorly insulated or short-circuited, etc., because the acquisition module is centralized power supply, so only one data acquisition module Poor insulation of external lines or short circuit may cause other data acquisition modules to fail to work normally

Abstract

The present invention relates to the technical field of fire control circuits, and especially relates to an isolated type fire detector data acquisition control circuit which is capable of solving the problem that traditional data acquisition modules influence each other, facilitating stability of medium and large fire alarm systems, and reducing the possibility of system false alarm. The isolated type fire detector data acquisition control circuit comprises a system control module and an interface module, wherein the system control module is connected with an analog value acquisition module, a code sending module, a communication module, and a storage module, the analog value acquisition module is connected with the code sending module, the interface module is connected with an internal power supply module, the communication module and the code sending module, the interface module is provided with an external power supply interface, an external detector interface, and a fire alarm controller interface.

Description

technical field [0001] The invention relates to the technical field of fire control circuits, in particular to an isolated fire detector data acquisition control circuit. Background technique [0002] In general industrial and civil construction, the fire alarm control system must be installed to ensure the alarm function when a fire occurs. The data acquisition module is used to collect the real-time situation of each detector on the site. Collect and analyze, and then transmit the analysis results to the fire alarm controller in real time. The fire alarm controller will report the specific location of the fire alarm or faulty detector according to the value transmitted from the data acquisition module to notify The personnel in the fire area can reduce the fire loss to the minimum, and a fire alarm system with a maximum of 9000 points can be formed between the data acquisition module and the fire alarm controller, which is conducive to the use of medium-sized and above sys...
