Problems solved by technology

[0004] The fire display panel is generally suitable for hotels, restaurants, office buildings, teaching buildings, computer rooms, communication rooms, banks, warehouses, libraries, archives and other places with fire hazards. It is intuitive and convenient, and can display detailed descriptions of alarm points. However, the existing fire display panel has the problem of delayed display of data, which is not conducive to the on-duty personnel to quickly confirm the fire danger and take fire-fighting measures

Abstract

The invention relates to the technical field of fire control circuits, and aims at providing a fire display panel circuit. The fire display panel circuit is characterized by comprising a second powersupply module and a converting unit, wherein the converting unit is used for converting analog signals into digital signals and outputting the digital signals; the second power supply module is used for providing working voltage and reference voltage for the converting unit, the input end of the converting unit is connected with a collecting module for collecting the digital signals of a fire scene, the output end of the converting unit is connected with a control module for adjusting and controlling a fire display panel, and the control module is connected with an address reading module for reading fire point coded addresses and a display screen module for displaying real-time data conditions of the fire scene. The fire display panel circuit is suitable for receiving and displaying information transmitted by an alarm controller in real time.

Description

technical field [0001] The present invention relates to the technical field of fire control circuits, and more particularly, to a fire display panel circuit. Background technique [0002] The fire display panel is a fire alarm display device installed on a floor or an independent fire zone. It is not connected to any linkage devices such as detectors and modules. It is used to display the monitoring and fire alarm conditions of each detector on the floor or the fire zone. There is a sound prompt or alarm sound. It is connected with the fire alarm controller through the bus, and processes and displays the data sent by the controller. [0003] The specific working process is: when a fire occurs, the fire alarm controller of the fire control center generates an alarm, and at the same time transmits the alarm signal to the fire display panel in the fire area. Alarm signal to notify fire area personnel. [0004] The fire display panel is generally suitable for hotels, restaura...
