Research On The Principle And Application Of The Anti-damaging Ability Of The Burglar Alarm System And Fire Alarm System

Since the burglar alarm systems born, invaders have tried to fight against them in every possible way. Some of the invaders destroy the scene alarms in order to steal the target things. If the protective shell of the alarms are enhanced, it is more difficult and expensive for people to manufacture them, and invaders may still use powerful tools to destroy the alarms.At places where fire alarms are installed, such as warehouses storing dangerous goods, petrol stations, gas stations, mines, even family’s kitchens and other places,Sometimes the explosion can make the alarm lose its function. If the alarms covered by flameproof enclosure, costs of alarms are increased, but it is still possible that the explosion damage the alarms.In order to guarantee the function of the burglar alarm systems under the condition that invaders destroy part of the on-site alarms, in order to guarantee the function of the fire alarms systems under the condition that explosion damage part of the on-site alarms,this paper researches a kind of alarm system which has characteristics that after part of the on-site alarms in the system are destroyed, the other alarms immediately send alerts.Any of the system consists of N alarms. In which each alarm communicates with other N-1 alarms. A alarm in the system will communicate once at planned intervals(for example, 3 seconds). If it does not receive information from any other alarm in planned intervals, this alarm will give an alarm.In order to verify the principle of the alarm system, this paper designs three kinds of samples: the first one is the burglar alarm network based on single chip computer with cable communications, the second one is the burglar alarm network based on Zigbee with the wireless communications, the third one is the fireproof alarm network based on Zigbee with the wireless communications. This paper describes the hardwareand software design of the new alarm systems in detail, and analyzes its working principles.This paper also presents the experimental test about the samples of new alarm systems. Each sample system consists of four alarms. The alarms in the system communicate with each other. I suddenly pull out one, or two, or three of the integrated block in the alarms, or cut off the wire to simulate these samples to be destroyed. The rest of the alarms give the alarm in 3 seconds, so as to realize the expected function.The alarm system of this paper uses several alarms to construct new systematic structure. Without changing the material of the alarm, without increasing the difficulty of manufacturing, the system’s survivability and security can be improved.The burglar system has greatly increased the difficulty of intruders. Fire protection system can greatly reduce the false negative rate fire.It is helpful to the protection of social property and has great significance to the security and harmonious development of society.
