Fire detector remote detection system based on Ad Hoc network

Abstract

The invention discloses a fire detector remote detection system based on an Ad Hoc network. The system comprises a data collection layer based on an Ad Hoc structure. The data collection layer comprises a cluster based on a tree-shaped topology structure. The cluster comprises a concentrator which is taken as a tree root and is used for storing topology structures of all routers in the Ad Hoc network, selecting transmission paths according to the stored topology structures and issuing information according to the selected transmission paths; the routers which are used for carrying out automatic networking, thereby forming a core tree network with the concentrator; and fire detectors which are used for carrying out automatic networking. After the routers consistent with conditions are selected, the fire detectors establish communication connection with the selected routers according to the tree-shaped topology structure, thereby accessing the core tree network. The system provided by the invention has the advantages of low cost, low power consumption, self-organization, multifunction and high stability. The fire detector remote detection system based on the Ad Hoc network provided by the invetion can be widely applied to firefighting security check work.

Description

technical field [0001] The invention relates to an ad hoc network technology and a detection technology, in particular to a fire detector remote detection system based on an Ad Hoc structure ad hoc network. Background technique [0002] Explanation of technical terms: [0003] Ad hoc network: a network that combines mobile communication and computer network. The information exchange of the network adopts the packet switching mechanism in the computer network. The user terminal is a portable terminal that can be moved. Each user terminal in the ad hoc network has a router As a host, the terminal needs to run various user-oriented applications, such as editors, browsers, etc.; as a router, the terminal needs to run the corresponding routing protocol, and complete the forwarding of data packets according to the routing policy and routing table And routing maintenance work, so the node is required to implement a suitable routing protocol. The goal of the ad hoc network routing...

Problems solved by technology

However, there are many shortcomings in the remote detection scheme of fire detectors based on wireless radio frequency technologies such as ZIGBEE and GPRS. For example: 1. ZIGBEE is a low-power network protocol based on the IEEE802.15.4 standard, but the cost is high and the protocol is complicated. For the specific application of remote detection of fire detectors, the analysis protocol has a large overhead, so the popular ZIGBEE has not been widely used in the field of remote detection of fire detectors, and the 2.4GHz frequency band used by ZIGBEE is extremely crowded, Bluetooth, wireless LAN , The microwave oven and the remote control of the garage door all work in this frequency band, which greatly increases the possibility of interference; 2. The GPRS fire detector remote detection solution needs a built-in GPRS communication module and is equipped with a SIM card for GPRS service. High cost and high power consumption
