Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with attached drawing and tool
Body embodiment, is described further the present invention：
As shown in Figure 1, for the flow chart of the implementation method of fence in the embodiment of the present invention, this method includes following step
Suddenly：
Step A1：Sending device sends broadcast singal to first receiving device and the second reception device；
Step A2：First receiving device is according to formulaIt is extrapolated at a distance from sending device
DAt,
Wherein, PRIt indicates to receive power, PTIndicate transmission power, GRIndicate receiving antenna gain, GTIndicate that transmission antenna increases
Benefit, λ indicate wavelength, andC is the light velocity in vacuum, and f is wavelength；
Second reception device is according to formulaItself and sending device distance dBt are extrapolated,
Wherein, PRIt indicates to receive power, PTIndicate transmission power, GRIndicate receiving antenna gain, GRIndicate that transmission antenna increases
Benefit, λ indicate wavelength, andC is the light velocity in vacuum, and f is wavelength.
Step A3：The distance dBt extrapolated is sent to first receiving device by the second reception device；
Step A4：First receiving device is according to formula：In electronics
In fence (formula -1), extrapolate whether sending device falls in fence,
If sending device is fallen thens follow the steps A5 in fence：First receiving device falls sending device to be enclosed in electronics
Information in column is sent to high in the clouds, no to then follow the steps A6：Sending device is fallen the letter outside fence by first receiving device
Breath is sent to high in the clouds.
Reception device continues to carry out line with the transmission signal under linchpin, as long as reception device does not receive the lower list of linchpin persistently
TAG radiofrequency signals, or suddenly occur not under linchpin list TAG radiofrequency signals, then receiver alarm is sent out by LORA
To high in the clouds；
The administrative area whether TAG comes across other reception devices is inquired in high in the clouds, and is deleted again and increased affected reception
List under device linchpin.
As shown in Fig. 2, reception device is installed on ground, it is equivalent to setting H2 and is equal to 0, then can uniquely be arrived at from transmitting terminal
Receiving terminal can only just use the direct transmission of LOS, without transmission and reflection, unless having other articles or personnel to provide in centre
The path of reflection, but because the antenna of receiving terminal just reduces many when falling into ground, it is equivalent to oriented antenna upward, such as
Fruit is placed in below ground installing antenna, more makes equivalent antenna patterns illustrated close to high directivity, so some interference
Signal is reflected, the chance that the antenna of receiving end receives is greatly decreased or signal weakens, therefore even if with the news directly transmitted
Number superposition, influences also little, therefore transmitting terminal and receiving terminal distance d are just easy to precisely by formula：
It extrapolates.
As shown in figure 3, including multiple sending devices and two reception devices A, B for being installed on ground, L is between A and B
Lateral distance length, fore-and-aft distance length of the W between A and B；Pass through formula：
In fence (formula -1), sending device is extrapolated
Whether fall in fence.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；For
For those skilled in the art, it can still modify to the technical solution recorded in previous embodiment,
Equivalent replacement either is carried out to which part or all technical features；And these modifications or replacements, do not make relevant art
The essence of scheme is detached from protection scope of the present invention.
