Embodiment

[0096] In this embodiment, a wireless alarm system composed of an alarm central unit 33 , four wireless router units 32 , and two alarm host units 31 is taken as an example for illustration. As shown in FIG. 3 , FIG. 3 is a schematic diagram of a wireless alarm system based on an ad hoc network according to an embodiment of the present invention. The ad hoc wireless network of the wireless alarm system is a four-layer tree topology. The number of wireless router nodes in the actual application system should be determined according to the coverage of the system and the number of alarm host units that need to be installed on site, so as to ensure that the wireless router can send the information of all alarm host units to the alarm center unit.

[0097] When an alarm message is generated, the alarm host unit has three subunits: an alarm detection subunit, an information collection subunit and a wireless terminal subunit. The alarm detection subunit is responsible for monitoring...

Abstract

A radio alarm system based on self-organized network comprises at least on alarm host unit for monitoring object region in real time and for generating alarm information being sent to alarm center unit through radio router, an alarm center unit for setting up self-organized network and for carrying out identification and analysis on received alarm information from said host unit as well as for issuing alarm information, at least one router unit for connecting said host unit to said central unit in order to realize information transmission between the two. Its radio alarming method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of alarm detection and wireless ad hoc network application, in particular to a wireless alarm system and method based on an ad hoc network. Background technique [0002] The alarm system refers to the installation of various detectors in each defense area of ​​the target area, or the setting of emergency call buttons. When the emergency call button is pressed, the alarm signal is transmitted to the monitoring computer in the alarm center through the alarm host in the target area, and the user information of the alarm occurrence is displayed. The alarm center processes the alarm information and contacts 110, 119, 120 and other units according to different natures, thereby speeding up the handling of emergencies. [0003] At present, there are mainly three types of commercial alarm system implementation methods: [0004] In the first category, the alarm host sends the alarm information to the alarm center or...
