Acquisition becomes a kind of conventional means for improving safety.However, in existing equipment and technology, wireless radio-frequency is only
For reading electronic tag data, and trigger mechanism is very passive, usually using the mobile as data acquisition of target object
Trigger mechanism.And although audio mining technique can position, there are one very big disadvantage, it is necessary to while the work together with camera
Make.Such as to the vehicle location of random honking after, immediately simultaneously start capturing system, take vehicle photo immediately, but if disobey
Chapter vehicle is fake-licensed car or the false car plate used, then can not determine the true identity of vehicle.And capturing system cost is higher, depending on
The data volume of frequency picture is larger, is not suitable for being set using on a large scale.And audio data and video data must be stored simultaneously, be made
It is longer or equipment is laid in more work system with the time, it is very big to the storage pressure of database.
Invention content
The purpose of the present invention is to provide a kind of less radio-frequency acquisition method and its system with audio collection function, energy
It is enough that effectively target object is positioned and improves the accuracy appraised and decided to target object and mitigates depositing for follow-up data library
Reserves pressure.
The present invention provides a kind of less radio-frequency acquisition methods with audio collection function, including following processing step：
Step 1：It acquires audio data and coordinate setting is carried out to target object；
Step 2：Electronic tag data is acquired to target object according to coordinate setting；
Step 3：By with same coordinate and identical time stamp audio data and electronic tag data be associated, and beat
Packet forms object uniqueness data packet；
Step 4：Object uniqueness data packet is subjected to banknote validation by network.
Preferably, the step 2 is judged by comparing filter algorithm filters duplicate data when carrying out comparing
Certain a data whether data of reading read with front is completely the same, and the data is abandoned if completely the same；Otherwise
Using the data as valid data, to which valid data are generated available electronic tag data.
Preferably, audio data is established acoustic array by the step 1, then obtains having distance parameter by acoustic array
Directional beam, directional beam direction and apart from corresponding polar coordinates be target object the elements of a fix.Before the step 3 is packaged
Audio data is first sampled compression.
The system for the less radio-frequency acquisition with audio collection function that the present invention also provides a kind of, including：Audio collection
Module output end connection processing device, for acquiring audio data and carrying out coordinate setting to target object；Less radio-frequency acquires mould
Block input terminal connects antenna, output end connection processing device, for acquiring electronic tag data to target object according to coordinate setting；
The processor output end connection network port, input terminal are separately connected audio collection module and less radio-frequency acquisition module, and being used for will
Audio data and electronic tag data with same coordinate and identical time stamp are associated, and are packed into object uniqueness
Data packet；Network port input terminal connection processing device, output end are connect by network with authentication unit, are used for object uniqueness
Data packet is sent to authentication unit by network；Authentication unit and network port network connection, are used for object uniqueness data
Packet carries out banknote validation.
Preferably, the less radio-frequency acquisition module is judged by comparing filter algorithm filters duplicate data
Certain a data that whether data of reading read with front when carrying out comparing is completely the same, is abandoned if completely the same
The data；Otherwise using the data as valid data, to which valid data are generated available electronic tag data.
Preferably, audio data is established acoustic array by the audio collection module, is then had by acoustic array
The directional beam of distance parameter, directional beam direction and apart from corresponding polar coordinates be target object the elements of a fix.
Preferably, audio data is first sampled compression by the processor before being packaged.
Compared with prior art, the present invention advantage is：
After being positioned in the present invention to target object by the audio of acquisition by and meanwhile acquisition electronic tag number
According to can effectively be positioned to target object and improve the accuracy and efficiency appraised and decided to target object.Form object
Uniqueness data packet, authentication unit only need to verify target object identity by the electronic tag data to the inside, when verification is effective
When can be judged as that the target object has made the corresponding behavior of audio, such as the loudspeaker that ring；It can be judged as when verifying invalid
Target object is illegal, such as automobile deck, can deliver subsequent artefacts' follow-up processing at once.Simultaneously because an electronic tag
The memory space of data is generally less than 1k, and opposite hundreds of k are even as high as million grades of video and picture amount of storage, hence it is evident that obtain more excellent
Storage more and retrieval advantage.
Description of the drawings
Fig. 1 is the less radio-frequency acquisition method flow diagram of the present invention with audio collection function；
Fig. 2 is the less radio-frequency acquisition system structure diagram of the present invention with audio collection function.
Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
As shown in Figs. 1-2, a kind of less radio-frequency acquisition method and its system with audio collection function, including：Audio
2 output end connection processing device 3 of acquisition module, for acquiring audio data and carrying out coordinate setting to target object；Less radio-frequency
1 input terminal of acquisition module connects antenna 4, output end connection processing device 3, for acquiring electronics to target object according to coordinate setting
Label data；3 output end of the processor connection network port 5, input terminal are separately connected audio collection module 2 and less radio-frequency acquisition
Module 1 for the audio data with same coordinate and identical time stamp and electronic tag data to be associated, and is packaged shape
In pairs as uniqueness data packet；5 input terminal connection processing device 3 of the network port, output end are connect by network with authentication unit 6,
For object uniqueness data packet to be sent to authentication unit 6 by network；Authentication unit 6 and 5 network connection of the network port, are used
In by object uniqueness data packet carry out banknote validation.
In electronic tag data to generating process, by comparing filter algorithm filters duplicate data, i.e., into line number
Certain a data whether read with front according to the data that read when comparing is completely the same, this number is abandoned if completely the same
