Abstract

The invention belongs to the novel technology for self-adaptively transmitting remote sensing data. Meteorological information acquired by a smoke sensing acquisition end, a temperature acquisition end, a humidity acquisition end, an infrared acquisition end, a video acquisition end and the like is digitized by using industrial grade communication network transmission equipment; and the digitized meteorological information is sent back to a monitoring center by using a network, wherein the network can be compatible with a plurality of network transmission modes such as the Ethernet, a transmission network, a WIFI, a 3G network, a signaling network and the like, intelligently calculates an optimum transmission mode according to a routing module, and sends data through the transmission mode. The technology for self-adaptively transmitting the remote sensing data can be widely applied to environments such as urban concentrated areas rich in wired and WIFI resources or the environments such as the field, forests, mountainous areas and the like which have no wired networks or the environment of poorer wireless network signals, and also can be applied to data transmission of mobile vehicle-mounted equipment as the vehicle-mounted equipment is always switched among different wireless networks or operator networks during moving. According to the technology, transmission parameters and transmission frequency of a field device, and an active warning function can be regulated at a center at any time due to the adoption of a central control mode, and areas in which emergent natural disasters are monitored can be discovered and reported at the first time, so the optimum network selection at this place and at the moment is ensured.

Description

The technology for self-adaptively transmitting of remotely-sensed data

Technical field

The invention belongs to the part in weather eye environmental monitoring and the disaster early warning system, particularly a kind of technology for self-adaptively transmitting of remotely-sensed data.

Background technology

Weather monitoring is the basis of meteorological work.Because a large amount of monitoring points need be placed in field, wilderness, meagrely-populated open-air mountain area or the large stretch of forest, because there do not have cable network often to need to be manually on duty.And vehicle-carried mobile weather monitoring device often can not be passed Monitoring Data back in real time owing to there is not fine Radio Transmission Technology.It is not very reliable problem that the technology for self-adaptively transmitting of the employing remotely-sensed data that the present invention invented just can solve no cable network and wireless network.

Summary of the invention

The Adaptive Transmission mode that the purpose of this invention is to provide remotely-sensed data, it is characterized in that: the data of data acquisition equipment collection all are connected data processing module, data processing module is connected to routing module again, and routing module links to each other with ethernet module, transmission network module, WIFI module, 3G module, signaling network module, spare module slot respectively.Its network preferred logic is characterised in that ethernet module prioritised transmission net module, the preferential WIFI module of transmission network module, the preferential 3G module of WIFI module, the preferential signaling network module of 3G module when sending same data.Its network preferred logic is characterised in that when sending different pieces of information, selects transport module according to the data layout that data processing module receives.In the data that data processing module receives, comprise the specified network preference policy, by this strategy execution.The logical relation of the logical relation prior claims 3 of claim 4, the logical relation of the logical relation prior claims 2 of claim 3.Send to data processing module according to the data of above logical relation by the data acquisition equipment collection, data processing module connects routing module and selects optimal network to send it back Surveillance center automatically according to data characteristics.The equipment and the network condition of last ethernet module, transmission network module, WIFI module, 3G module, signaling network module, spare module slot all feed back to data processing module by routing module, upload core processor by data processing module again, judge so that core processor is made network strategy with data acquisition equipment.

Benefit of the present invention is the field that data collection point can be arranged on any no cable network, realizes 24 hours monitoring, to the data of gathering and video information promptly and accurately complete beam back monitoring center.Need not artificial on duty and manual intervention, and can be applicable to the data in real time transmission of vehicle-mounted weather monitoring equipment and need not doing the manual data migration after mobile unit comes back to the base by the time.Adopt wireless network with low cost rather than expensive satellite circuit, greatly the single-point operating cost of Jiang Diing.Simultaneously can be by the five distant management such as remote control, remote measurement, remote regulating, remote signalling and remote viewing of this technology realization to the data collecting device.

Embodiment

The employed transmission standard of ethernet module is 100BASE-FX (100BASE-FX is particularly suitable for being suitable under the situations such as the environment of electrical Interference, big distance connection or high secure environment).

The employed transmission standard of transmission network module is the E1 line interface of modulation pcm encoder mode.

The employed transmission standard of WIFI module is the full compatibility standard of IEEE 802.11b/g/n.

The employed transmission standard of 3G module, compatible three kinds of transmission technology TD-SCDMA/WCDMA/CDMA2000 of mainstream carrier at present.

The employed transmission standard of signaling network module, compatible mainstream carrier's GPRS/CDMA transmission technology at present.

When routing module by ethernet module, transmission network module,, WIFI module or 3G module any one when carrying out data transmission, all use ICP/IP protocol to land central server automatically.

When carrying out data transmission by the signaling network module, routing module select TCP/UDP to connect the communication transmission platform transceive data of Surveillance center.

After one group of data transmission finished, data processing module (8) will reconnect to guarantee to realize breaking, certainly the high stability of recovery and circuit automatically from newly carrying out next logic of organizing data ordering.

Concrete workflow principle sees Fig. 2 for details.。
