The improvement of structure belongs to Monitoring of drought technical field especially suitable for the construction and operation of damage caused by a drought automatic monitoring system engineering.
Background technique
Traditional soil moisture monitor device can be divided into contact pin type and two kinds of cannula type from shape；It can be divided into from principle
Time domain method (TDR) and frequency domain method (FDR).Corresponding time domain method is all needle sensor；Corresponding frequency domain method is all annular sensing
Device.
Although time domain method instrument does not have to carry out formula calibration, each component is all separation, is not integrated, to bring all
More problems.Such as: separate type instrument is placed in the farmland in field, and safety, operation stability, reliability are all unable to get guarantor
Card；Terminating machine and battery are placed in the external hanging type metal box on ground or more, and summer in the winter temperature difference is especially big, and (summer the temperature inside the box is up to 80
Degree Celsius or more), the service life of electric elements and battery can be all greatly affected；Sensor in placing into the soil, due to
Probe level is inserted into soil, and the soil of 10cm, 20cm soil layer can not just carry out farming, causes monitoring data to lose representative,
Its monitoring data is also just not used to Analysis of drought regime and evaluation.High frequency cable between terminating machine and sensor is very long, causes instrument
Power consumption increases；Cable does not allow to give a discount, and brings great difficulty to running protection.
Although frequency domain method instrument can integrate, do not influence soil cultivation after being inserted into soil, but need to carry out instrument with grouting method
Device installation, the stable time is longer, and done site by site is needed to carry out the adjustment of instrument parameter, just can guarantee the monitoring accuracy of instrument, and every
Spring in year will compare observation, and to examine whether its monitoring accuracy meets required precision, instrument must be adjusted when being unsatisfactory for
Parameter, construction cost and operating cost are all very high.
The presence of problems above brings very much, very big difficulty to realization Monitoring of drought automation, serious to hinder
Monitoring of drought automation realization.
Summary of the invention
A kind of needle tubing convolution soil moisture monitor disclosed by the utility model, thoroughly solves traditional soil moisture
Monitoring instrument is difficult to integrate, sensor is difficult to fixed problem.
A kind of needle tubing convolution soil moisture monitor described in the utility model, technical solution are as follows:
Including shell, terminating machine, sensor, rechargeable battery, terminal machine support, battery bracket and solar panels；
The shell is the tubular structure of sealing, and bottom is equipped with battery bracket in shell, and rechargeable battery is fixedly mounted on
The working power of monitor is provided on battery bracket；Shell internal upper part is additionally provided with terminal machine support, and terminating machine is fixed on terminating machine
On bracket, it is electrically connected by power supply line with rechargeable battery；It is required according to acquisition soil level in different height position in shell
It sets, is respectively arranged with a sensor and probe；Sensor by high frequency cable respectively with terminal mechatronics, by acquisition
The soil signal of different height is sent to terminating machine, and using electromagnetic wave, the length with soil moisture content in propagation time are built on probe
Mathematical model is erected, and then calculates the water content of tested soil；
Instrument zero and charging line interface are additionally provided in the upper end of shell.
The utility model has the following positive effects: passing through the biography of different location in it using the cannula structures of closing one
Sensor distribution, passes to terminating machine for the electronic information of acquisition in real time, utilizes the length in electromagnetic wave propagation time on probe
Mathematical model is set up with soil moisture content, and then calculates the water content of tested soil, is used for damage caused by a drought automatic monitoring system, it can
To be widely used in the monitoring soil moistures such as farmland, mountain forest, grassland, there is monitoring accuracy height, do not have to carry out formula calibration, data
The features such as representative good, construction cost and operating cost are all low, safety is good, instrument service life is long.
It is fixed thoroughly to solve the problems, such as that each component separation of contact pin type soil moisture monitor device, sensor are difficult to.It realizes
Contact pin type soil moisture monitor device it is highly integrated so that carrying out that the automatic monitoring accuracy of damage caused by a drought is high, data using the instrument
Representative good, safety, construction cost and operating cost are low.
The utility model has multiple advantages:
1, low signal attenuation and instrument power consumption drop.Become 35 centimetres of longest at least 6 meters of high-frequency signal line length, greatly drops
The low decaying of high-frequency signal, greatly reduces Overall Power Consumption.
2, guarantee that monitoring data are representative.Sensor position is fixed, can real-time perfoming farming operation, guarantee instrument week
The soil environment enclosed is consistent with the soil environment in farmland, to ensure that monitoring data are representative.
3, extend instrument service life.Terminating machine, battery all move to underground by storing in the external hanging type cabinet of ground, avoid
Instrument longtime running under the high temperature conditions, to improve the service life of instrument.
4, instrument safety is improved.Terminating machine, battery etc. are fully integrated into pipe and are embedded to underground, eliminate external hanging type
Cabinet, reduces the attention of stranger, to improve instrument in the safety in field.
5, engineering construction cost and operating cost are reduced.External hanging type cabinet is eliminated, instrument metal shell is used instead nonmetallic
Tubing shortens high-frequency signal line, to reduce engineering construction cost.Due to not having to carry out formula calibration, without done site by site
Parameter adjustment is carried out, to reduce the operating cost of system.
