Exhibition fire protection monitoring system

Abstract

The invention discloses an exhibition fire protection monitoring system, comprising a monitoring module, a wireless communication module, a main controller, an alarm module, a fire extinguishing module, a monitoring terminal and a power supply module; the monitoring module is connected with the main controller through the wireless communication module; the alarm module, the fire extinguishing module, the monitoring terminal and the power supply module are connected with the main controller; the monitoring module comprises a smoke sensor and a heat source monitoring device; the fire extinguishing module comprises a carbon dioxide fire extinguishing device and a spraying device which are connected with the main controller; the power supply module comprises a voltage input end, a first diode,a second resistor, a first operational amplifier, a first resistor, a third resistor, a second capacitor, a first triode, a second triode, a fourth resistor, a second operational amplifier, a direct-current power supply, a first capacitor, a fifth resistor, a sixth resistor and a voltage output end. According to the system in the invention, diversified requirements can be met, and the circuit issimple in structure, low in cost, convenient to maintain, high in safety and reliability.

Description

technical field [0001] The invention relates to the field of exhibitions, in particular to an exhibition fire monitoring system. Background technique [0002] The exhibition hall often holds short-term or long-term exhibitions for popular science education, product display promotion or sales, etc. During the exhibition, due to the high density of the population area and the large flow of people, the conference staff of the exhibition are mainly responsible for the exhibition display, reception affairs, etc., and the fire hazard is not easy to be found. Once a fire occurs, it is easy to cause huge property losses and personal injuries. . Some existing exhibition fire monitoring systems can monitor in real time whether there is a fire during the exhibition. Once a fire occurs, it can promptly extinguish the fire and evacuate the crowd. The traditional exhibition fire monitoring system adopts the Zigbee communication method, which is relatively simple and cannot meet the dive...

AI Technical Summary

Problems solved by technology

The traditional exhibition fire monitoring system adopts Zigbee communication mode, which is relatively simple and cannot meet diverse needs

In addition, the power supply part of the traditional exhibition fire monitoring system uses many components, the circuit structure is complicated, the hardware cost is high, and it is inconvenient to maintain

In addition, due to the lack of corresponding circuit protection functions in the power supply part of the traditional exhibition fire monitoring system, such as the lack of current limiting protection functions and signal interference prevention functions, the safety and reliability of the circuit are poor
