Description
Technical field
The present invention relates to information acquisition of Internet of things and transmission technology, more particularly to a kind of data acquisition based on multiple antennas
Radio transmitting device and system.
Background technology
Developing rapidly with technology of Internet of things, the technology such as RFID, Zigbee is because having motility height and the low spy of cost
Point is widely used.But because the prior arts such as RFID are all using single channel, therefore multiple spot cannot be realized simultaneously
Gather and transmit, and carry out time-division slot transmission due to the collision problem of multiple spot simultaneous transmission will be solved and lead to efficiency of transmission relatively
Low, power consumption is larger.
Content of the invention
The technical problem to be solved in the present invention is to overcome the drawbacks described above of prior art presence, provide one kind to enable many
Point synchronous transfer, efficiency of transmission is higher, the less data collection radio transmitting device based on multiple antennas of power consumption and system.
The technical solution adopted for the present invention to solve the technical problems is：A kind of data collection radio based on multiple antennas passes
Defeated apparatus and system.
The data collection radio transmitting device based on multiple antennas of the present invention, including wireless aggregation node, the described no congruence
Poly- node adopts the aerial array received single-shot more, and wireless aggregation node includes at least two radio frequency moulds being operated in different channels
Block, one of radio-frequency module is used for sending signal, and the radio-frequency module for sending signal is furnished with omnidirectional antenna, other radio frequencies
Module is used to receipt signal, and the radio-frequency module for receipt signal is provided with beam antenna.
The data collection radio Transmission system based on multiple antennas of the present invention, including described wireless aggregation node, also includes
One group of wireless sensor node.Wireless aggregation node is used for the radio-frequency module of sending signal to one group of wireless senser by one
Node sends instruction, and receives the number from different radio sensor node by multiple radio-frequency modules for receipt signal
According to.The wireless sensor node that the radio-frequency module that each is used for receipt signal is operated under same frequency with one is communicated,
The different radio-frequency modules for receipt signal and different wireless sensor communication.
All with wireless radio frequency modules, wireless sensor node can lead to wireless sensor node proposed by the present invention
Cross frequency switch operating in different channels.
Wirelessly between aggregation node and wireless sensor node, communication is realized by two ways：
Set P0 as wireless aggregation node, P1, P2 ... Pm, Pm+1 ... Pn is the wireless sensor node in P0 institute coverage
Point, m, n represent node ID, and 1≤m≤n, Pm represent the wireless sensor node that node ID is m；Set CH0 as public letter
Road, CHj represents the channel that channel number is j, and j represents channel number, j >=1；Illustrate taking wireless sensor node Pm as a example, its
He is the same Pm of wireless sensor node working method：
Wireless sensor node and channel are one-to-one relations, and that is, in addition to common signal channel CH0, each wirelessly passes
Sensor node can be assigned to the channel of a determination, and all wireless sensers channel each other differs, each solely
Vertical；
One kind is that, all in channel CHj, working channel does not need to cut for wireless sensor node Pm sending signal and receipt signal
Change；And in wireless aggregation node P0 sending signal, if wireless aggregation node P0 does not need to carry out with wireless sensor node Pm
Communication, then wireless aggregation node P0 is in channel CH0 sending signal, if conversely, wireless aggregation node P0 needs and wireless senser
Node Pm is communicated, then the channel of wireless aggregation node P0 sending signal switches between CH0 and CHj：Work as wireless senser
When node Pm has the demand of data transfer, report transmission demand, wireless aggregation node P0 in channel CHj to wireless aggregation node P0
After channel CHj receives transmission demand, the channel of sending signal is switched to CHj from CH0 by wireless aggregation node P0, and in channel
CHj sends the control signaling uploading data to Pm, after the control signaling that wireless aggregation node P0 has sent upload data, wirelessly
The channel of sending signal is switched to CH0 from CHj by aggregation node P0 again, and Pm receives the control signaling uploading data in channel CHj
Afterwards, Pm in channel CHj to P0 transmission data, P0 after channel CHj has received data, P0 again by the channel of sending signal from CH0
It is switched to CHj, and sends, to Pm, the control signaling that data transfer completes in channel CHj, treat that P0 has sent number in channel CHj to Pm
After the control signaling being transmitted, the channel of sending signal is switched to CH0 from CHj by P0 again, so far just completes data
Once transmit；The different channels that are sent in of wireless aggregation node switch over, the reception of wireless aggregation node in fixed channel,
Need not switch, and the reception of wireless sensor node and transmission are operated in same channel, need not switch.
Another kind is, arbitrary wireless sensor node Pm only in channel CH0 receipt signal, only in channel CHj sending signal,
Working channel needs to switch, and the channel of wireless aggregation node P0 sending signal, all the time in CH0, need not switch；Work as wireless sensing
When device node Pm has the demand of data transfer, wireless sensor node Pm reports to wireless aggregation node P0 in channel CHj channel
Transmission demand, afterwards wireless sensor node Pm be switched to channel CH0 to receive the control signaling from wireless aggregation node P0,
Wireless aggregation node P0 after channel CHj receives the transmission demand of wireless sensor node Pm, in channel CH0 to wireless sensing
Device node Pm sends the control signaling uploading data；Wireless sensor node Pm receives the control letter uploading data in channel CH0
After order, it is switched to channel CHj and sends data to wireless aggregation node P0, be switched to channel CH0 after being sent completely and wait the no congruence
The confirmation signaling of poly- node P0, wireless aggregation node P0 sends out to wireless sensor node Pm in channel CH0 after having received data
Send the control signaling that data transfer completes, wireless sensor node Pm is receiving the control signaling from wireless aggregation node P0
Afterwards, complete the once transmission of data；
The transmission of wireless aggregation node is fixed on certain channel and is transmitted, and the reception of wireless aggregation node is different from sending out
The channel sending is received, and multiple receptions of wireless aggregation node are also respectively at different channels, independently of one another, mutually do not do
Disturb.The reception of wireless sensor node and transmission are operated in different channels.
Both the above mode all can realize single point-to-multipoint, simultaneously gathered data the purpose transmitted.
The radio-frequency module for sending signal of wireless aggregation node corresponds to one group of wireless sensor node, and wireless convergence is saved
The radio-frequency module that each of point is used for receipt signal corresponds to a wireless sensor node determining respectively；The same time, no
Line aggregation node receives the data from different radio sensor node by the different radio-frequency modules for receipt signal, real
Existing Multipoint synchronous collection and transmission.
In the present invention, described wireless aggregation node adopt single-shot more receive aerial array, be capable of multiple spot and gather simultaneously
And transmission.Meanwhile, the radio-frequency module for receipt signal is furnished with beam antenna, emitted energy concentrate on determination direction so that
Transmission range one timing transmission power reduces, thus reducing node power consumption, overcoming existing internet of things data acquisition cannot realize
The defect of Multipoint synchronous transmission.
