Problems solved by technology

[0006] 1. Generally, it can only do some fire detection, data reporting, and alarm through the Internet of Things platform after a fire alarm occurs. It does not have the ability of real-time fire alarm linkage, and its application scenarios are limited;
[0007] 2. The wireless signal is susceptible to external interference, causing the fire detection node equipment to go offline;
[0008] 3. If there is a problem with the gateway device, a large number of nodes will be offline, which will greatly affect the stability of the wireless fire alarm system

Embodiment 1

[0035] Please refer to figure 2 This embodiment provides a relay type fire display, including a power module, a relay module, a building module, and a monitoring module.

[0036] The power module, including the main electromechanical interface circuit, a backup motor, and a host backup fault monitoring circuit; the main backup fault monitoring circuit monitors the real-time state of the main electromechanical interface circuit and the backup circuit circuit and report to the building display module.

[0037] The main electrical interface circuit is an AC220V interface circuit that supports the AC220V AC transfer DC15V buck, which is powered on a relay type fire display. The backup electrical interface circuit is a lithium battery interface circuit, a built-in 12v / 2600mAH lithium battery, and is continuously powered by a relay type fire display disk after the main electrical interface circuit is disconnected. Also includes a charging management circuit, using MP2759 as a charging...

Embodiment 2

[0043] Please refer to image 3 This embodiment provides a wireless fire alarm system, including several wireless fire detection node devices and a fire alarm controller, further comprising several relay types according to any one of claims 1 to 6. Disc; the relay type fire display disc is deployed in a star network, and at least 3 relay-type fire display is wirelessly communicated with the same wireless fire detection node device, receives the detection data uploaded by wireless fire detection node devices, and sends Give a fire alarm controller; the relay type fire display disk is connected to the system fault between any trunking fire display disk, and the system fault information is synchronized to other trunking fire display disks, and reported Give a fire alarm controller. The fire alarm controller determines whether a fire has occurred, if the result of the judgment is a fire, the linkage-free fire display is issued to the corresponding area, which is displayed by relay type...

Abstract

The invention discloses a relay type fire display panel, which relates to the technical field of fire alarm, and comprises a power supply module, a main power interface circuit, a standby power interface circuit and a main and standby power fault monitoring circuit, the main and standby power fault monitoring circuit monitors the real-time states of the main power interface circuit and the standby power interface circuit and reports the real-time states to the building display module. a relay module is used for receiving detection data uploaded by the wireless fire detection node equipment or other relay type fire display panels and sending the detection data to an external fire alarm controller; or receiving fire information issued by an external fire alarm controller and transmitting the fire information to the building display module; a building display module receives the data sent by the power supply module and the relay module and displays the data; a monitoring module monitors the running state of the relay type fire display panel in real time and reports the running state to the outside through an antenna; the invention further discloses a wireless fire alarm system composed of the relay type fire display panel. According to the invention, the stability of fire alarm is greatly improved.

Description

Technical field [0001] The present invention relates to the technical field of fire alarm, in particular to a relay type fire display disc and a wireless fire alarm system. Background technique [0002] Fire display As an important part of the fire alarm system, the applications in industrial and civil buildings are increasingly wide, and the safety of the people's life and property plays an important role. The fire display disk is mainly mounted in the floor or independent fireproof area, can communicate with the fire alarm controller, when fire alarm, can display the number, region and other information of the fire alarm detector node device, and issue an acoustic alarm. [0003] With the rapid development of the Internet of Things technology, wireless fire alarm control systems are more advantageous in more and more scenes. More convenient installation, low construction cost, all node equipment networking, is conducive to intelligent management. [0004] In the existing wired ...
