Description
Technical field
Patent of the present invention belongs to fire monitoring field, especially a kind of novel radio combined type automatic fire alarm system.
Background technology
Automatic fire alarm technology is the Building Fire Fighting System of core, is the important leverage of prevention and containment building fire.
Fire engineering.In recent years, China's automatic fire alarm engineer application technology realizes very fast development, but due in practical application
In, the communications protocol of automatic fire alarm system is inconsistent, and automatic fire alarm engineering technology level also falls behind relatively, also exists
Some comparison distinct issues.1. the scope of application is too small.China's automatic fire alarm system technology is than developed countries such as American and Britain
It starts late, fitting limit is mainly《Code for fire protection design of high rise buildings》、《Code for fire protection design of buildings》Defined field
Institute and position, and easily causing the middle-size and small-size fire fighting and rescue of the dead group's wound of group and community resident family even partial high-level house
Installation automatic fire alarm system is all not specified by, the scope of application is too small, and the precautionary measures are not in place.2. intelligence degree is low.I
Although the fire detector that state uses all has carried out intelligentized design, since the parameter of senser element detection is less, supports system
The accuracy shortage of immature, the various algorithm of software development of system is verified enough, scene of fire parameter database is unsound etc., fire
Calamity automatic alarm system is difficult to accurately judge the concentration of particle (flue gas), scene temperature, the intensity of light wave and fuel gas
The indexs such as concentration, electromagnetic radiation are caused to report late, be reported by mistake, to fail to report situation more.3. networking degree is low.The fire of China's application
119 dynamic alarm system forms are substantially with regional fire automatic alarm system, collection automatic Fire Alarm System and control centre
Based on automatic fire alarm system, installation form is mainly collecting and distributing control mode, is established one's own system, self-isolation, still non-forming region
Domain property networking automatic fire alarm system.4. assembly connecting mode is to be improved.Automatic fire alarm system with multiple-way system and
Be based on bus connection mode, between detector and alarm and controller using two or more pieces copper core insulated conductor or
Copper core cable poling connects, and there are the shortcomings that consumptive material is more, of high cost, poor anti jamming capability.Meanwhile copper conductor high temperature resistance
Poor, easy to wear, system construction repair is complicated, the reliability for affecting automatic fire alarm system and widely application.5. fire
More problems are failed to report in the wrong report of calamity automatic alarm system.Since the installation environment of fire detector is extremely complex, various sensings in addition
There is certain inadequate natural endowments in terms of fire is detected for device, and it is specific in combustion can not accurately to sense various substances
All many-sided delicate variations occurred such as sound wave, spectrum, radiation, smell, to generated different-grain diameter in fire generating process
There is detection " blind area " with the cigarette of color, wrong report, failing to report phenomenon happen occasionally.6. the application of extreme early fire detecting and alarm technology is also
It is nearly at blank.Foreign countries have developed suitable clean room high sensitivity smoke detector alarm system, such as laser type height
Sensitivity smoke fire detector, air suction type high sensitivity smoke detector alarm system and gas fire detecting and alarm system
System, compared with common fire detection alarm system, detectivity improves two orders of magnitude, even more, these systems
The principles such as laser particle counter, laser light scattering are employed to monitor by guard space, it is increased how many next with particle in unit volume
Judge whether that fire occurs, system can identify potential fire risk in a few houres or several days before fire generation, realize super
Incipient fire is alarmed.And the technology China is still in infancy needs further to research and develop application at present.
In view of the above-mentioned problems, automatic fire alarm application technology should further be conceived to the new situations of current Overseas Development,
Accelerate the process that renovates, strengthen, to digital technology and new process, new diseases, improving system capability, making fire automatic
Alert applications technology develops towards highly reliable, low wrong report and networking, intelligent direction.
