A kind of online soil testing assemblies
Technical field
The utility model is related to a kind of soil testing assemblies, it is adaptable to environment and meteorology, agricultural breeding, water conservancy, soil moisture in the soil
The fields of measurement of feelings and various particulate matter water content.
Background technology
Continuous expansion and technology popularization with agricultural, increasing agricultural breeding family are merely not only concern crop life
Long aerial temperature and humidity, and more begin to focus on the humiture of soil.In agricultural breeding field, it is often necessary to analysis soil
The moisture and temperature of earth.Moisture is too high or too low, just suppresses until ceasing breathing, photosynthesis, the vital movement such as growth.Soil
Humidity determines the moisture supply situation of crops, directly affects the growth of crop root.Only soil moisture is suitable, root water uptake
Poised state is can be only achieved with leaf transpiration.Soil moisture is too low, forms soil drought, and photosynthesis can not be normally carried out, and drops
The yield and quality of low crop;Serious water shortage causes crop wilting and death.Soil moisture is too high, deteriorates soil aeration, shadow
The activity of edaphon is rung, makes the vital movements such as breathing, the growth of crop root hindered.
Although having substantial amounts of soil testing assemblies on the market now, existing soil testing assemblies are required for people
Part work and part study takes humiture numerical value, and whether Temperature and Humidity Control can only judge according to the experience of workman and need to adjust soil temperature and humidity
Value.The methods of this manually control humiture, both consume manpower, and inaccurately, and automaticity is very low;Long-term
It is placing into the soil in use, can by electrolysis interference, pop one's head in easily by acid and alkali corrosion, cause probe fail or sensitivity decline,
So as to not dynamic, the moisture and temperature of reflection soil in real time.Therefore, the waste of resource is not only resulted in use, and
And it is also not obvious enough to the improvement of soil temperature and humidity.
Utility model content
The utility model can not learn the soil temperature and humidity of crops whenever and wherever possible mainly for user, and make phase in time
It should handle, Temperature and Humidity Control is being adapted to the environment of crop growth, and then have impact on growth and the yield of crops.By closing
The planning of reason, design and build a set of Intelligent Measurement and regulation soil temperature and humidity device, can be with the soil of Intelligent Measurement crops
Earth humiture, is wirelessly sent to background service, is then adjusted according to opening or closing for the order automatic control equipment that receives
The value of soil greenhouse degree is saved, the humiture environment of suitable crop growth is reached.For example:When soil drought, device is certainly
Dynamic alarm, while control system automatic control switch water pump and valve, to realize the automation of irrigation.If coordinating some to add
Sensor, the water parameters needed for soil water evaporation amount and crops can also be calculated.So as to reduce manual operation
Uncertain factor, reduces or solves water resource waste.
The utility model proposes a kind of online soil testing assemblies, it includes acquisition module, control module, wireless biography
Defeated module, display module, power module and audible-visual annunciator, it is characterised in that:
The acquisition module is placed in monitoring detection probe, in the probe insertion soil, and is connected by electrical wiring to A/D
Change-over circuit via digital signal processing circuit to be connected to the control module;
The power module is connected to the control module, acquisition module, wireless transport module, display by filter circuit
Module and audible-visual annunciator;
The control module connects the A/D change-over circuits, filter circuit, wireless transport module, display module and acousto-optic
Alarm.
Wherein, the stable data signal after the A/D change-over circuits conversion sends the control module to.
Wherein, the control module uses programmable controller.
Wherein, the chip model of the A/D change-over circuits is AD7794.
Wherein, the chip model of the wireless transport module is SY-RSCM302.
Wherein, the digital signal processing circuit uses the TMS320LF2407A chips of TI companies.
The online soil testing assemblies that the utility model is provided, easy for installation with high stability, attended operation letter
It is single;Monitor detection probe and use stainless steel (anti-electrolysis) material, can hide in soil and use for a long time, it is not rotten by the soda acid in soil
Erosion;Measurement accuracy is high, dependable performance, economy and durability;Can Multi-point detection, it is ensured that the normal concentration in region, it is to avoid indivedual probes
It is excessive or not enough that failure or sensitivity decline the irrigation that causes, influence practical application effect, it is to avoid soil moisture is too high to be deteriorated
Soil aeration, influences the activity of edaphon, makes the vital movements such as breathing, the growth of crop root hindered, root system
Anoxic, asphyxia, last death.And the growing environment of crop can be checked in mobile phone, pad, it can reflect dynamically, in real time, exactly
The moisture and temperature of soil.
