A kind of intelligent inspection tour instrument based on GPS and RFID
The utility model belongs to line upkeep and cruising inspection system, relates in particular to railway, electric power, communication line and patrols and examines equipment.
Computer technology fast development in recent years, the work of patrolling and examining is scientific also to make automatic control technology constantly penetrate into many fields with standardized management, sub-district security personnel, workshop inspection, subway are patrolled and examined, power circuit patrol, mine safety is patrolled and examined etc. has all begun to relate to, and also has many industries and department or prepare to use the automatic control technology realization to patrol and examine the intellectuality of work.Cruising inspection system also develops into present induction type from the earliest contact on hardware, adopt noncontact radio-frequency card, contactless card technology, and information acquisition device need not contact and promptly can read information button, can carry out wireless telecommunications.
In general, the electronic cyclic system is by being patrolled and examined equipment, logging, transmission medium, patrolling and examining information management system and form.So-called by the equipment of patrolling and examining, simply say the equipment that just is mounted in the place that the personnel of patrolling and examining need check, patrolling and examining a little can be to be made of active equipment, also can be to be made of inactive component; So-called logging, then patrol and examine a kind of electronic/mechanical device that uses in the middle of the process for the personnel of patrolling and examining, it has specific 26S Proteasome Structure and Function, or finish the automatic record and the storage of the information of patrolling and examining, or finish the automatic emission of the information of patrolling and examining, or finish and patrol and examine the transmission of Information triggering, the general structure of concrete function and cruising inspection system is closely related; Transmission medium is different and different according to the structure of cruising inspection system.Transmission medium can be wired copper cable medium, also can be the electromagnetic wave medium, can also be to transmit information in other wireless or wired modes; Patrol and examine information management system and be based on a computer management system of ordinary PC, realize comprising the information comprehensive management system that patrols and examines that patrols and examines the demonstration of dynamic real-time information, patrol record information management, patrols and examines tasks such as information demonstration.
Technology from using mainly contains three kinds of electronic cyclic systems: based on the cruising inspection system of information button, based on the cruising inspection system of RFID technology and based on the cruising inspection system of GPS/GIS technology.
Information button (iButton) is that automatic identification chip, the information button that U.S. MAXIM company produces adopts globally unique 12 bit digital numbering, and corresponding one an of information button is patrolled and examined equipment.From principle of work, can find out, logging must contact when reading information button information, and caused the inevitable shortcoming of contact cruising inspection system thus: 1. logging must contact very exactly just with information button and can read information, operation inconvenience, especially at night; 2. information button exposes, and is easily destroyed; 3. information button exposes vulnerable to pollution, causes loose contact.
RFID is a radio-frequency (RF) identification, and it is a kind of automatic identification technology of noncontact two-way communication, and basic characteristics are that card reader does not need directly to contact with electronic tag.Though the shortcoming that the characteristics of information have overcome information button system is read in the noncontact of RFID, and its defective is also arranged: the 1.RFID cruising inspection system can only write down patrolling and examining a little of Discrete Distribution, can't write down polling path, can not apply to line data-logging; 2. this system can show the personnel that patrol and examine through equipment, and record is not patrolled and examined personnel and whether checked equipment by working specification.
GPS is a GPS, is the strategic navigational system by U.S. Department of Defense's development in 1973.At present, GPS has been widely used in geodetic surveying, accurate location, navigation and time service field.GIS is a Geographic Information System, also is widely used in information applications such as communications and transportation, resource exploration, tourism.Principle of work based on the cruising inspection system of this technology is: when the personnel of patrolling and examining execute the task, hand-held logging receives GPS (Global Positioning System (GPS)) data, behind the arriving signal equipment, instrument to be inspected is effectively located the position of back preservation equipment, task termination is with the data importing management host, analyze in conjunction with GIS (Geographic Information System) functional software, generate and patrol and examine report.Its defective is: 1. if outdoor equipment can't effectively be located at the satellite information that can't receive under the blocking of other objects more than 4; 2. general hand held GPS receiver bearing accuracy is about 25 meters, and when patrolling and examining device distribution when concentrating, can't distinguish from the gps data that records is the data of which equipment.
More than analyze and can find out, though existing electronic cyclic than traditional inspection management mode advanced person many,, many shortcomings are also arranged.
Problem to be solved in the utility model is: under the situations such as abominable, equipment dispersions of point more than long lines, environment out of doors, independently working, assist the personnel of patrolling and examining to carry out the line data-logging work of facilities such as railway, electric power, communication.The utility model can be used for various line data-loggings, realizes patrolling and examining process record, patrols and examines supervision and management, patrols and examines intelligently guiding, patrols and examines function such as Device Diagnostic, for facility important, that safety is relevant provides reliable maintenance guarantee.
