Description

A kind of long-range situation monitor and communication system and method based on two-tier network structure

Technical field

The invention belongs to communication technical field, be specifically related to a kind of long-range situation prison based on two-tier network structureSurvey communication system and method.

Background technology

Consider safety factor, risk object and the field work of environment annex have certain menace, needAt guarded region, front end monitoring equipment is installed, then, front end monitoring equipment is by communication network and long-range chargeCenter to center communications, that is: long-range charge center is by communication network forward end monitoring equipment sending controling instruction; SoAfter, the situation information of the audio frequency and video form in front end monitoring equipment acquisition monitoring region, then by this situation informationAnd status information of equipment returns to long-range charge center by communication network, long-range charge center is by dockingSituation information and the status information of equipment received are analyzed, and realize showing risk object and environmental situationShow and assess.

At present, to the communication network of risk object and the field work of environment annex, generally adopt following two kinds of sidesFormula: (one) wireline communication network: wireline communication network is mainly used in the hard-wired feelings of front end monitoring equipmentUnder condition, by wireline communication network, realize communicating by letter between front end monitoring equipment and long-range charge center. RatioAs, in some known probability of causing danger larger region or place, as oil reserve storehouse, chemical hazardProduct warehouses etc., take to install the front end prisons such as fixing monopod video camera, The Cloud Terrace thermal infrared imager, smoke alarmMeasurement equipment, it carries out information interaction by wireline communication network and long-range charge center, finally by long-range chargeCenter is controlled and information gathers. Carry out communication by wireline communication network, due to network cable clothThe reason such as put, be only only applicable to hard-wired front end monitoring equipment, and cannot be applied to maneuver mode operationFront end monitoring equipment. (2) cordless communication network:, by cordless communication network, realize front end monitoringCommunicating by letter between equipment and long-range charge center, because wireless network does not need to arrange the reasons such as network cable,Therefore, utilize cordless communication network communication, the front end monitoring equipment that has both been applicable to fixed form to install carries outState control, also can carry out motor-driven control to front end monitoring equipment movably, and in addition, front end monitoring is establishedStandby situation information and the status information of equipment collecting passes back in long-range charge by cordless communication networkThe heart. The advantage of this kind of mode is: can control in real time movably front end monitoring equipment, realize motor-driven deployment,Have advantages of that flexibility is good; But its communication distance does not often reach the requirement of remote monitoring, particularlyRelate to the wireless image transmission equipment that long-range situation monitors, based on cordless communication network, its communication distance generally onlyFor 5-8km; Once distance increases, the reliability of communication will reduce greatly, have greater risk.

As can be seen here, how to design one can guarantee front end monitoring equipment flexible, again can ensure super far awayApart from the communication system of reliable communication, it is the important technology guarantee of long-range situation monitoring system successful Application.
