Specific embodiment
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
The non-scope for limiting invention.On the contrary, the present embodiment includes the institute of spirit and the intension scope falling into attached claim
Changing, revise and equivalent, this should be understood by embodiment of the present invention person of ordinary skill in the field.
The invention provides a kind of soil moisture and the sonde configuration of Nutrient change detection device, as it is shown in figure 1, described inspection
The probe surveyed includes M3 fastening screw 30, water proof ring 31, agnail body 32, annular copper electrode 33, aluminum annular-shaped alloy electrode 34, insulation
Body connector 35, cone aluminum alloy anode 36, insulator shell 37；Described cone aluminum alloy anode 36, insulator connect
Part 35, aluminum annular-shaped alloy electrode 34, insulator shell 37, agnail body 32 sequentially clamping are also fastened screw by core admittedly by M3
Fixed, described annular copper electrode 33 is embedded in insulator shell 37 and does not contact annular aluminum alloy anode 34 and agnail body 32, described
Water proof ring is embedded in agnail body one end near annular copper electrode 33；Described annular electrode 33 and aluminum annular-shaped alloy electrode 34 are constituted
Capacitance type sensor, described aluminum annular-shaped alloy electrode 34 and cone aluminium alloy 36 constitute resistance sensor.The present invention implements
In example, puncture soil to agnail portion by the conical probe part of described detection device and submerge soil carries out fixed point detection.
In embodiments of the present invention, the capacitance type sensor that described annular electrode 33 and aluminum annular-shaped alloy electrode 34 are constituted is surveyed
The capacitance detecting signal obtained is processed as reflecting the data of soil moisture content transformation, described aluminum annular-shaped alloy electrode 34 by motherboard circuit
Constitute, with cone aluminium alloy 36, the voltage detection signal that resistance sensor records and be processed as reflecting the number of change of soil nutrient
According to.
In embodiments of the present invention, logical test using capacitance sensor output frequency, record frequency change little, all at 73-
75KHz, the fluctuation of water causes detection frequency unstable, and the factor affecting frequency maximum is exactly the capacitor board degree of depth in encroached water,
This conclusion can deduce the relation between electrode detection output frequency and the water content of soil.It it is below computing formula
QUOTE It is applicable to north soil property
QUOTE It is suitable for south soil property
QUOTE For soil moisture content, kd is the dielectric constant of soil,Molten heavy for soil
The computing formula of electric capacity C is as follows:
