Description
Technical field
The present invention relates to the sensor that frozen soil in meteorological observation is measured.
Background technology
The measurement data of frost penetration is the indispensable Back ground Information of the engineering constructions such as road, building, oil transportation, water delivery,
Even more spring plantation, variety of crops adjustment etc. agricultural production foundation.The observation of frost penetration include the soil freezing number of plies and
The observation of the depth of freezing, is one of basic observation mission of China's most area meteorological station.
China's frost penetration observation is used《TB1-1 type freezing meters》The method of artificial observation.External frozen soil observation is typically adopted
With《Dan Nilinshi freezing meters》Be also the method for artificial observation, measuring principle is identical, i.e., observation person daily timing will in depth under
0.5~4.5 meter of water filling flexible rubber hose for portraying length mark proposes ground, with hand by centimetre pinch and pinch the hardness of flexible pipe and judge
What whether the water in sebific duct froze to judge underground freezes the number of plies and the depth of freezing.This manual measurement method is not only observed
Personnel are worked hard, the error brought of being expanded with heat and contract with cold there is also the scale for portraying length and pinching for personnel's subjectivity operation are pinched, bend and break
The error in judgement that bad original natural freezing state is brought.Up to now, the domestic self-reacting device equipment also observed without frozen soil,
Though attempt to design frozen soil sensor using time domain radioactive method, capacitance measurement, photovoltaic measurement, thermometry etc.,
But because the precision of measuring frozen is unable to reach 1 centimetre, and sensor processed complex exists in the measurement of multi-level frozen soil
Larger difficulty, is also unfavorable for the measurement of relatively deep frozen soil, therefore is not widely applied.
With the raising of China's meteorological observation automaticity, many meteorological observation key elements successively realize automatic Observation,
The Ground Meteorological automated system of modernization is gradually formed.In order to fill up the blank of China's automatic Observation frozen soil method, increase is seen
The reliability of frozen soil is surveyed, human error is reduced, improves meteorological automatic Observation level, urgent need, which develops one kind, can realize that automation is distant
Survey the sensor of frozen soil.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, accuracy of observation is high（1cm）Performance is stable, can be widely applied to
Frozen soil observation sensor in meteorological automated system.
Learnt by theory and practice：The essence that soil freezes is freezing for soil institute's water content, the heat of soil freezing
Physical process still keeps the principal character of water freezing process in main aspect.It is successively heat exchanged and mainly passes through present in soil
Heat exchange pattern is carried out, and ground somewhere goes to zero with the thermograde in layer soil level direction, the thermograde of vertical direction compared with
Greatly.Cataclysm this " freezing resistance characteristic ", and this can occur for the conductive resistance based on the aqueous solution containing conducting particles in phase transformation
The reappearance of characteristic extraordinary regular feature again, the enlightenment that we obtain is：Sensing matter can be made of impure water to be made
Sensing element, situation is freezed by measure that the phase transformation situation of water can react same layer soil.
The technical scheme is that design is a kind of to freeze resistive frozen soil sensor, it by column type sensor main body part, underground outside
Sleeve, heat insulating mattress, connection socket, automatic collector are combined, wherein the column type sensor main body part is by nonmetallic materials
Process, inside sets several centre-to-centre spacing and freezes detecting electrode in bubble chamber, chamber, sense jelly bubble connectivity slot, electrode cable as 1cm sense
Seal groove, water injection hole, osculum；The outer cuff of column type sensor main body part has the anti-sebific duct that rises, and inserts in the outer sleeve of underground, top is worn
Heat insulating mattress is crossed with being connected socket connection；Detecting electrode is embedded in sense and frozen in bubble cavity wall in the chamber, and its wire is sealed through electrode cable
Groove is corresponding with the bore for connecting socket to be sequentially arranged in order connection；Bubble chamber is frozen in sense and sense is frozen bubble connectivity slot and filled originally by water injection hole
Water；The automatic collector be placed in connection socket top, it is interior provided with electronic commutator, single-chip computer control system, memory,
Power supply circuit, communication interface and site setup, running status are shown；Realize that circuit and transmission are believed with frozen soil sensor and host computer
Number effective connection.
The present invention is compared with known technology, and its is simple in construction, scientific and reasonable, technical performance stable, accuracy of observation is high（It is reachable
±1cm）, it is easy to spread application, solve meteorological observation frozen soil automation key problem in technology.
