In first water tank 110 level it is quiet after, fix the first mounting base 112 using the first clamping device 113；
The position of the light and scale 130 that are emitted according to Geoplane 116, the second electric pushrod 120 of control adjust the
The height of two water tanks 124 is to make the 2nd UWB sensor 128 and the first UWB sensor 114 be in sustained height；
In second water tank 124 level it is quiet after, fix the second mounting base 126 using the second clamping device 127；
Start first motor 108 and the second motor 122, first motor 108 is made to drive the rotation of the first UWB sensor 114, the
Two motors 122 drive the rotation of the 2nd UWB sensor 128；
Measurement result is read from the first display screen or second display screen.
Working principle: when the density to field crops 200 measures, staff is by the first measurement vehicle 101 and the
Two measurement vehicles 102 are pushed into the two sides of field crops 200 respectively and make the first of the first measurement vehicle 101 and the second measurement vehicle 102
UWB sensor 114 and the 2nd UWB sensor 128 are as far as possible close to field crops 200.
On smooth ground, the first UWB sensor 114 and the 2nd UWB sensor 128 are set in same level height
When, graduation mark 131 of the laser irradiation that Geoplane 116 issues on scale 130 is default scale.Not due to field soil
It is smooth, when first measures vehicle 101 and the second measurement vehicle 102 is parked in the ground of different height relatively, start the first electric pushrod
The height of 106 the first water tanks 110 of adjusting keeps the first UWB sensor 114 high not higher than the height and Geoplane 116 of kind of plant
In the height of kind of plant；Start the second lifting platform of the second electric pushrod 120 driving 121 to adjust the opposite of the second stock 129
In the height of the first stock 115.Guarantee the first UWB sensor 114 and the 2nd UWB sensor 128 when carrying out descending operation
Not higher than the height of field planting object.Until the laser irradiation that Geoplane 116 emits is on the graduation mark 131 of scale 130
Scale when being default scale, then the first UWB sensor 114 and the 2nd UWB sensor 128 are in same level height.
When the water in the first water tank 110 and latter two the static water tank of the second water tank 124 is gradually static, and the first kickboard 111
It is also remain stationary under the buoyancy of water respectively with the second kickboard 125 and all in horizontal stationary state.At this point, with the first folder
It holds device 113 and the second clamping device 127 clamps the first mounting base 112 and the second peace under horizontal stationary state respectively
Seat 126 is filled so that the first UWB sensor 114 and the signal wave energy of the 2nd UWB sensor 128 transmitting are in same level height
Degree.It ensure that the first measurement vehicle 101 and the second measurement vehicle 102 are surveyed on rough field soil in this way
The first UWB sensor 114 and the signal wave of the 2nd UWB sensor 128 transmitting are at sustained height and energy phase mutual connection when amount
It receives, to guarantee the accuracy of measurement result.
At the first UWB sensor 114 and the 2nd UWB sensor 128 when same level height, start first motor 108
With the second motor 122, first motor 108 is made to drive the rotation of the first UWB sensor 114, the second motor 122 drives the 2nd UWB to pass
Sensor 128 rotates.First motor 108 and the revolving speed difference of the second motor 122 ensure that when the first UWB sensor 114 and second
UWB sensor 128 turns to the signal wave emitted when being mutually aligned and can mutually receive to complete to detect on sustained height.The
The data that one UWB sensor 114 and the 2nd UWB sensor 128 will test respectively are uploaded to the first display screen and the second display
It is read on screen for staff.
As the use of UWB sensor, it is generally used to detecting distance.Further, it is possible to be realized by multiple space lengths
Space orientation.The element task principle of UWB sensor is using flight time telemetry.Flight time telemetry mainly utilizes letter
Flight time carrys out the distance between measuring node number between two asynchronous receiver-transmitters.The two-way each module of time-of-flight method is from starting
Start generate an independent timestamp.The pulse of Ta1 transmitting request property of the transmitter of modules A on its timestamp
Signal, module B emit the signal of a response property at the Tb2 moment, by modules A in oneself time stamp T a2 reception.By
This can calculate the flight time of pulse signal between two modules, so that it is determined that flying distance S.
Distance: S=C [(Ta2-Ta1)-(Tb2-Tb1)] (C is the light velocity).
The application using the electromagnetic wave different principle of spread speed in different media, using traditional UWB sensor as
A kind of new usage mode is placed into the two sides of object under test, and medium directly affects the detection data of UWB sensor, or
Say that the data of UWB sensor detection are influenced by the medium that electromagnetic wave is passed through.The electromagnetic wave of UWB sensor release has passed through sky
Gas and kind plant, kind plant include certain moisture.The electromagnetic wave of air and the moisture in kind plant in UWB sensor
Accounting on motion path directly affects the measurement data of UWB sensor.The dielectric constant of water is much larger than air.That is
The data of UWB sensor detection mainly depend on the quantity of plant or the water of plant on motion path.Electromagnetic wave is in kind of a plant
Spread speed in interior moisture is much larger than the spread speed in air.Same kind of kind of plant its moisture content substantially phase
Together.
The data that wherein accounting of the kind plant on Electromagnetic Wave Propagation path and UWB sensor detect are linear.Or
Person says, plants the density of plant and data that UWB sensor detects are linear.The data that can be detected according to UWB sensor
Obtain the density of kind of plant.
