Description

Based on the fire alarm system of RFID
Technical field
The present invention relates to fire alarm field, particularly relate to a kind of fire alarm system based on RFID.
Background technology
RFID is the abbreviation of RadioFrequencyIdentification, i.e. radio-frequency (RF) identification, and be a kind of contactless automatic identification technology, it identifies destination object automatically by radiofrequency signal, can carry out item tracing and exchanges data rapidly.Identification work need not manual intervention, can work in various rugged surroundings.RFID technique identifiable design high-speed moving object also can identify multiple label simultaneously, swift and convenient to operate.RFID technique is born in World War II, and it is the successor of traditional bar code technology, is also called " electronic tag ".
The basic functional principle of RFID technique is also uncomplicated: after label enters magnetic field, receive the radiofrequency signal that plug-in reader sends, the energy obtained by means of induction current sends out storage product information in the chips (passive label or passive label), or the signal (ActiveTag of a certain frequency is initiatively sent by label, active label or active tag), plug-in reader reads information and after decoding, delivers to CIS and carry out relevant data process.
The rfid system of complete set, be made up of reader and electronic tag i.e. so-called transponder and application software system three part, its principle of work is the radio wave energy that Reader launches a characteristic frequency, send in order to the data of driving circuit by inside, now Reader just received in sequence unscrambling data, gives application program and does corresponding process.
Can be divided into haply with the communication between rfid card sheet reader and electronic tag and energy-sensitive mode: inductively and back scattering be coupled two kinds.The RFID of general low frequency mostly adopts the first formula, and higher-frequency adopts the second way mostly.
Reader is different with technology according to the structure used can be read or read/write device, is that rfid system information controls and processing enter.Reader is made up of coupling module, transceiver module, control module and interface unit usually.Between reader and transponder, the general half-duplex operation mode that adopts carries out message exchange, and reader provides energy and sequential by coupling to passive balise simultaneously.In actual applications, the management functions such as collection to object identification information, process and teletransmission can be realized further by Ethernet or WLAN etc.Transponder is the information carrier of rfid system, and transponder forms parasitic element by coupling element (coil, microstrip antenna etc.) and microchip mostly.
RFID has following Performance Characteristics:
1. rapid scanning, RFID identifier identification simultaneously can read several RFID label tag.2. volume miniaturization, various shapes, RFID does not limit by size and shape in reading, not to be required to be reading degree of accuracy and to have coordinated fixed measure and the press quality of paper.In addition, RFID label tag more can toward miniaturization and various Form Development, to be applied to different product.3. contamination resistance and permanance, the carrier of conventional barcode is paper, is therefore easily polluted, but RFID has very strong repellence to materials such as water, oil and chemicalss.In addition, because bar code invests on polybag or outer packing box, so especially easily lost; RFID label deposits in the chips by data, therefore can from stained.4. reusable, just cannot change after bar code printing now gets on, RFID label tag then can repeatedly increase newly, revise, delete the interior data stored of RFID label, facilitate the renewal of information.5. penetrability and without barrier read, when capped, RFID can penetrate nonmetal or nontransparent materials such as paper, timber and plastics, and can carry out penetrability communication.And bar code scanner when closely and when not having object to stop, just must can distinguish wanding.6. the memory capacity of data is large, the capacity of one-dimensional bar code is 50Bytes, the maximum capacity of two-dimensional bar can store 2 to 3000 characters, and the maximum capacity of RFID then has several MegaBytes. along with the development of memory carrier, and data capacity also has the trend constantly expanded.The data quantity carried needed for following article can be increasing, can expand the demand also corresponding increase of capacity to label.7. security, due to RFID carrying is electronic type information, and its data content can, via cryptoguard, make its content not easily be forged and alter.RFID gets most of the attention because of its characteristic such as remote reading, high storage capacity possessed.It not only can help an enterprise significantly to improve the efficiency of goods, information management, can also allow sale enterprise and manufacturing enterprise interconnected, thus receiving feedback information more exactly, demand for control information, optimizes whole supply chain.
Existing fire hazard monitoring generally adopts artificial monitoring, some supervisory system is equipped with a lot of camera, and unified display in Control Room, directly observed by staff, on the one hand, this mode wastes a lot of human resources, on the other hand, staff may not observe fire conditions in time due to too fatigue, shines into property even human loss.
In addition, existing fire hazard monitoring is dispersed in the region of various places for each, generally can only carry out decentralized supervisory control, cannot accomplish Centralized Monitoring, and human resources require higher.
