The long-range unmanned sensing network of satelliteTechnical field
The present invention relates to a kind of sensing network, particularly a kind of long-range unmanned sensing network.
Background technology
In some engineering projects or scientific research process, usually need to gather a large amount of data, by carrying out the running status of facilities for observation to the real-time analysis of data or carrying out statistical research.And the gatherer process of data needs a large amount of manpower of cost and time usually.
Further, to have inconvenient traffic when the position of image data is positioned at, when being unfavorable for health or being in mobile status for a long time, how to obtain data message or sending instruction to data acquisition sensing device just becomes a difficult problem.
Summary of the invention
The object of the invention is to overcome the defect existed in prior art, provide a kind of satellite long-range unmanned sensing network, this system is gone to without the need to staff after installation is complete and is garrisoned, and can obtain real time data information and can carry out remote control.
For achieving the above object, design proposal of the present invention is as follows:
The long-range unmanned sensing network of a kind of satellite, comprises sensing network and remote measurement and control center; Sensing network comprises some sensors and node, is undertaken alternately between sensor and node by wired or wireless network; After collecting data, sensor transfers data to node by wired or wireless network, then by node real-time Transmission to remote measurement and control center; Remote measurement and control center also can send instruction, and instruction is transferred to specific one or several sensor by node, then carries out associative operation by specific sensor according to instruction.
More specifically, between node and remote measurement and control center, directly carry out remote data transmission by satellite, not by the restriction of Distance geometry signal transmission.
More specifically, node carries out 24h uninterrupted power supply by solar panel and accumulator, and wherein, accumulator is full of rear sustainable power supply 30 days, utilizes solar powered when having sunlight in 30 days, and charges for accumulator; And sensor is powered by solar panel, in time there is no the sun, utilize the equipment connected to power, and be also 24h uninterrupted power supply.
More specifically, above-mentioned sensing network can be fixed, also can be portable; The scope of this sensing network is hundreds of rice, has both been applicable to the data acquisition of small space, and has also been applicable to the data acquisition of open area.
More specifically, the instruction that remote measurement and control center sends can be return data, Update Table uploads frequency, Update Table form, intercept image scene and Self-resetting etc.
Advantage of the present invention and beneficial effect are: the mode adopting the long-range real-time transmission data of satellite, can not by the limit value of distance between remote measurement and control center and sensing network data collection point; Without the need to staying scene after staff installs sensing network at the scene, human resources are saved; And sensing network can be fixed on a position, also can be in mobile in, can be used for the data acquisition in certain project of backcountry, also to can be used in the truck container of movement the isoparametric monitoring of temperature etc., applied widely.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment one (fixed)
Be positioned at the air monitering sensing network at height above sea level 4km place, somewhere, Tibet, comprise sensing network 1 and remote measurement and control center 2; Sensing network comprises sensor 11 and node 12, and sensor has temperature sensor, pressure transducer, humidity sensor, air mass sensor etc.; Be connected alternately by wireless network between sensor 11 with node 12; When a certain sensor 11(is as pressure transducer) collect data after, namely pressure transducer 11 is transferred to node 12 by wired pressure data by this some place, then by node 12 by satellite real-time Transmission to being positioned at measurement and control center of Pekinese 2; In addition, be arranged in measurement and control center of Pekinese 2, when staff finds that a certain data (as pressure data) occur abnormal, this pressure transducer 11 of command request return data again can be sent, this instruction is sent to the node 12 being positioned at height above sea level 4km place, somewhere, Tibet by satellite, transferred to pressure transducer 11 by node 12, then by pressure transducer 11, data are back to measurement and control center of Pekinese 2 by node 12.
Embodiment two (movable type)
A temperature monitoring sensing network in mobile truck household freezer, comprises sensing network 1 and remote measurement and control center 2; Sensing network 1 comprises several temperature sensors 11 and node 12, is arranged in the diverse location of household freezer; Be connected alternately by wireless network between sensor 11 with node 12; After a certain temperature sensor 11 collects data, namely the temperature data at this some place is transferred to the node 12 be positioned at outside truck household freezer by this temperature sensor 11 by wireless network, then by node 12 by satellite real-time Transmission to the measurement and control center 2 being positioned at Shanghai; In addition, be arranged in the measurement and control center 2 in Shanghai, when staff thinks that the data frequency of gained is too little, when needing more data, command request temperature sensor 11 can be sent and improve data upload frequency, this instruction is sent to the node 12 outside the truck household freezer of movement by satellite, transfer to the temperature sensor 11 in household freezer by node 12, and temperature sensor 11 will upload frequency by Update Table automatically.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
