Description
Technical Field
The invention relates to the technical field of automatic fire alarm systems, in particular to an automatic fire extinguishing alarm and fire fighting integrated control system.
Background
Along with the development of modern construction in China, the construction of various industrial buildings is accelerating, and in the construction process, especially the prevention of fire is more and more emphasized by people. The national fire-fighting law has issued and implemented relevant laws and regulations, and the prevention of fire in engineering construction is improved to the height of the laws and regulations. The principle of 'prevention is the main and the combination of prevention and elimination' which is completely implemented for the fire-fighting system and marks that the automatic alarm system for fire disasters plays a more important role. Conventional automatic fire alarm systems, which employ a single fire alarm controller, have not been adapted to the needs of such dispersed large-scale industrial buildings.
The existing combustible gas monitoring and alarming systems are roughly classified into (1) systems formed by a gas sensor, a power supply, a signal conversion circuit, a single chip microcomputer, a nixie tube display, an alarm and a light emitting diode. The gas sensitive probe is a semiconductor gas sensitive sensor, the working principle is that as the concentration of combustible gas near the probe rises, the semiconductor component after being electrified and preheated has the adsorption effect on the sensitive gas, the internal chemical reaction is accelerated,
the resistance value of the sensor of the gas-sensitive probe decreases exponentially, and the change of the resistance is converted into an electric signal which can be measured by a signal conversion circuit. The change of the resistance value of the sensor is brought into the time constant of the square wave generator to influence the width of the square wave, and the change of the width of the square wave is directly related to the concentration of the fuel gas to reflect whether the fuel gas leakage phenomenon exists or not. The singlechip designed at the rear stage of the monitoring circuit can accurately measure the width of the method by utilizing an internal timer, and the detected gas concentration parameter can be calculated by formula calculation. And the alarm is displayed through a nixie tube, and when the monitored concentration value exceeds a preset danger threshold ], the alarm is immediately driven to work. The combustible gas monitoring system realized by the advantages of the system has the advantages of comprehensive monitoring, high cost performance and reliable operation. But requires computational accuracy. (2) The device consists of a monitoring element, an amplifying circuit, an alarm system and a display system. The monitoring principle of the combustible gas monitoring and alarming system mainly comprises a catalytic combustion principle, a thermal conduction principle, a semiconductor principle, an infrared absorption principle and the like. Most combustible gas monitoring alarms are manufactured by adopting the catalytic combustion principle. The working principle of the combustible gas alarm manufactured by adopting the catalytic combustion principle is based on a balance bridge, one bridge arm of the balance bridge is a thermosensitive element, the surface of the thermosensitive element is coated with a catalyst, when air flowing through the bridge arm contains combustible and explosive substances, unbalanced electric signals are output, and the content of the combustible and explosive substances in the air can be obtained according to the signal magnitude. When the gas concentration reaches a preset alarm value, the instrument gives out sound and light alarm.
