Description
Technical field
The present invention relates to a kind of wireless sensor network node, relate in particular to the packet that will from a plurality of channels, receive that radio sensing network big data quantity real-time collecting uses and carry out the multichannel data receiving center node submitted to Surveillance center at faster speed after the standardized packages.
Background technology
Wireless sensor network is nearly ten years emerging technologies that progressively grow up, it combines multinomial technology such as sensor technology, embedded computer technology, the communication technology, power technology, can make people obtain comparatively detailed, reliable information down with environment at any time and place.
Wireless sensor network technology provides good intelligent distributed monitoring network for the test macro of realizing the engineering structure test, provides good methods for realizing high efficiency, high accuracy, low weight, intelligentized structural test system.Structural test is an important component part of structural design.Its task is by in a planned way the performance behind the structure stand under load being observed and measurement parameter (as stress, displacement, fatigue life, amplitude, shake frequently etc.) is analyzed, reaching the service behaviour and the bearing capacity of structure are made correct evaluation and estimation.Because the importance of engineering structure safety, people have given bigger attention to structural test.Along with the development of science and technology and social demand, subjects is tested and the large scale developing test to overall structure by the single component test in past.
With the aeronautic structure Strength Test System is example, and at present, characteristics such as aeronautic structure Strength Test System ubiquity measurement point is many, scale is big have caused its test system lead-in wire complexity, impost big; In addition, the intellectuality of test system integral body, networked degree are not high, cause experimental test efficient not high.To make up N road acquisition channel, each passage per second carries out the distributed data acquisition of M strain acquirement, the aeronautic structure Strength Test System that in real time image data is transferred to Surveillance center simultaneously is an example, usually each acquisition node has 4 road strain acquirement passages, adopt 10 AD that data are changed, each passage collection produces the packet that data segment is 8 * 4 * 16bits=512bits 8 times, this data segment added some necessary informations and encapsulate each data of back with the IEEE802.15.4 standard be surrounded by 648bits, the radio-frequency module CC2420 by node sends to base-station node.The data volume of whole system has: (N/4) * (M/8 * 648) bits/s.Get N and be 320 and satisfy the many requirements of aeronautic structure strength test strain acquirement passage, get M and be 32 and satisfy the required strain sample frequency requirement of aeronautic structure strength test, promptly whole system needs 80 acquisition nodes, and the data of generation reach 207.36kbits/s.
Make up pilot system based on single channel list base station radio sensor network framework.When M was 32, each acquisition node produced the 1s/32 * 8=0.25s that is spaced apart of packet.The acquisition node synchronous acquisition causes acquisition node to produce packet simultaneously, adopt time division multiple access to insert (Time Division Multiple Access, TDMA) mechanism sends the packet that acquisition node produces, and promptly each node basis obtains independently data sending time slots a: 0.25s/80=3.125ms in the address separately.Support the data rate of 250kb/s, this time slot to be difficult to realize the transmission of all succeeding of all data based on IEEE802.15.4 standard 2.4GHz frequency range.Simultaneously, because the serial ports maximal rate has only 256000 baud rates, the employing single base station is difficult to finish the transmission to the 207.36kbits/s data.
Given this, propose to make up pilot system based on many base station radios of multichannel sensor network framework of IEEE802.15.4 standard.Adopt 10 base-station nodes to send the data to Surveillance center, the data packet transmission of 8 acquisition nodes is finished in each base station, and the data volume of each base station transmits is 20.736kbits/s, can adopt 57600 baud rate serial ports speed.For increasing the sending time slots of acquisition node, adopt 10 data channels, each channel constitutes Star Network by 8 acquisition nodes and a base-station node.Because the data in the different channels do not produce collision, this moment, the sending time slots of each acquisition node was: 0.25s/8=31.25ms, this time slot make the data packet transmission success rate obtain bigger raising.The packet that acquisition node sends can reliable transmission to Surveillance center, the throughput of whole data collection network gets a promotion.
Simultaneously, the many base station architectures of multichannel need carry out time synchronized to the acquisition node that is positioned at the different pieces of information channel.This paper introduces a synchronizing channel synchronous acquisition of the acquisition node that is positioned at different channels is provided support; Introduce a management node and be responsible for sending the order of Surveillance center to synchronizing channel, and the different data channel that switches in cycle sends synchronization message in the network work process, the synchronous acquisition of acquisition node is provided support at the network initial time.
There is shortcoming in said system: at present, the data of each data channel all are to be transferred to Surveillance center by the base-station node on this data channel by serial ports, serial ports quantity and serial ports speed all are the bottlenecks of this system, be necessary to develop multichannel data receiving center node, the function of this node is the packet that receives in a plurality of data channels, packet is carried out standardized packages, and submit data to Surveillance center at faster speed.
At present about not relating to the relevant patent of radio sensing network big data quantity real-time collecting both at home and abroad with multichannel data receiving center node.
