The instruction of reason human-machine operation, the instruction of control radio frequency communications unit read operation, parsing acquisition data carry out inner decoding compiling, and
The operation such as server is transferred data to, therefore main control unit generallys use the MCU of high-performance, low-power consumption
(Microcontroller Unit, micro-control unit) Lai Shixian, for example use STM32F103 series processors, the application couple
This is without limitation.To realize radio communication function, network communication unit can be with for radio frequency communications unit and antenna array cooperating
It is embodied as any a network communication chip, in actual implementation, in tag read-write equipment further includes the other assemblies such as power supply, this
Application no longer repeats one by one.Antenna array at least two tag read-write equipment is arranged at the necessary river of fish migration
In, and at least two antenna arrays are spaced a predetermined distance along the water (flow) direction in river, which is preset experience
Value, for example it is separated by 2 meters of settings between every two antenna array.Several antenna elements are respectively included in each antenna array, are led to
In normal situation, each antenna array includes at least two antenna elements, as Fig. 3 respectively includes 4 antennas with each antenna array
For unit, the water (flow) direction in this at least two antenna elements towards river is set side by side.Meanwhile each tag read-write equipment also divides
The network communication unit and server 30 for not including by itself, which are established, to be communicated to connect to realize that data are transmitted.
Fish label and each tag read-write equipment in the application are based on RFID (Radio Frequency
Identification, radio frequency identification) technology synergy work, the working principle of the system is as follows:
Fish label 10 in the application is passive label, and without internal power supply, it internal being penetrated under normal circumstances
Frequency processing chip does not work.Each tag read-write equipment emits the radiofrequency signal of preset frequency by respective antenna array respectively,
For example tranmitting frequency is the low frequency electromagnetic frequency wave of 134.2KHZ, which mainly carries out work by way of inductive coupling
Make, that is, there is transformer coupled effects between the antenna array of reader and the antenna module of fish label 10, pass through reading
It writes the voltage incuded in the antenna module of device alternating field acted on built in fish label 10 to be rectified, supply voltage use can be made,
Therefore the antenna module when the fish for possessing fish label 10, which swim across antenna array, to be entered in its working range, inside fish label 10
13 receive the electromagnetic wave of the preset frequency, to generate induced current and drive to radio frequency processing chip 12, work as antenna
When component 13 receives the signal of sufficient intensity, radio frequency processing chip 12 is activated, and radio frequency processing chip 12 launches outward storage
The corresponding label data of fish label 10, label data includes at least the tag number of the fish label 10, and each tag number is
Uniquely.Tag read-write equipment incudes by antenna array and receives the signal of the transmission of fish label 10, obtains after carrying out data compilation
The label data sensed is sent to by the corresponding label data of fish label 10, each tag read-write equipment by network communication unit
Server 30, in system diagram as shown in Figure 1, when the fish for possessing fish label 10 swim across the day in the first tag read-write equipment 21
When wire matrix, the first tag read-write equipment 21 senses label data and is sent to server 30;When the fish continues to swim across the second mark
When signing the antenna array in reader 22, the second tag read-write equipment 22 senses label data and is sent to server 30, service
Each label data that device 30 is sent according to each tag read-write equipment can determine shoal of fish dynamic, such as by calculating fish label 10
By the successive time of the antenna array in the antenna array and the second tag read-write equipment 22 in the first tag read-write equipment 21, according to
Preset logic can judge to swim out of the state still state of swimming back when the shoal of fish is current, remaining shoal of fish dynamic can also be according to need
It obtains.
It should be noted that since several antenna elements in each antenna array are to be set side by side, if all days
Line unit all works at the same time, then antenna element can interfere with each other that the effective of entire antenna array is greatly lowered each other
Read range, it is demonstrated experimentally that the read range of entire antenna array only wraps in the case where all antenna elements all work at the same time
The range of about 0.5cm around antenna array is included, this read range is meaningless in this application, and the probability of skip is very big.
Therefore the tag read-write equipment in the application is controlled several antenna elements in each antenna array and is carried out by the way of poll
Work, two antenna elements being disposed adjacent do not work at the same time, such as in antenna array shown in Fig. 1, if antenna array according to
Secondary includes tetra- antenna elements of A, B, C, D, then the course of work of the antenna array are as follows: A and C works, B and D do not work;A
It does not work with C, B and D work, such circulation.This poll operating mode effectively shields the phase between antenna element
Mutually interference, effectively increase the detection range of entire antenna array, factually test statistics indicate that, using poll operating mode feelings
Under condition, the read range of each antenna array is the range for including about 15cm around antenna array, as long as fish enter this model
Enclosing can be detected, and be effectively prevented skip.Switch operating between antenna element simultaneously, entirely circulates in 4ms and completes,
The speed of poll is exceedingly fast, therefore skip will not occur because antenna element switches.
Above-described is only the preferred embodiment of the application, and present invention is not limited to the above embodiments.It is appreciated that this
The other improvements and change that field technical staff directly exports or associates without departing from the spirit and concept in the present invention
Change, is considered as being included within protection scope of the present invention.
