Abstract
The utility model relates to a soil temperature detection device. The traditional soil temperature senor has a certain defects in terms of leakproofness, perceptive temperature compensation and the like when being applied to soil temperature measurement and is cumbersome to operate as the soil layer measurement depth control is generally subjected to field measurement. The soil temperature detection device comprises a probe pipe which is formed by mutually nesting a heat-conduction metal steel pipe (1) and a heat-insulation PVC (Polyvinyl Chloride) pipe (2) together at an interval, wherein a temperature sensor (3) is arranged in the heat-conduction metal steel pipe part of the probe pipe and connected with an analog-digital conversion circuit (4), the analog-digital conversion circuit (4) is connected with a master controller (5), and the main controller is connected with a display (6). The soil temperature detection device is used for soil temperature detection.
Description
Technical field:
The utility model relates to a kind of soil moisture pick-up unit, belongs to the geophysical techniques field.
Background technology:
The soil moisture is one of environmental element of foot end, it changes along with factors vary such as weather, landform, vegetation, soil types and physical propertys, the soil moisture not only can affect formalness and the inner structure of plant, and can affect the variation of organic substance in plant.The height of the soil moisture also concerns sowing morning and evening, minute grain growth and decline and the security problems of surviving the winter of crop.In depth of soil 0.5m, so carry out the mensuration of the soil moisture, grasp temperature changing regularity due to the main Root Distribution of crops, all significant to agricultural production real time service and theoretical research.
At present soil moisture measuring equipment relatively more commonly used mainly adopts contactless, transistor PN, thermistor and the integrated digital temperature sensor measurement soil moisture of infrared spectrum, and the sensor contact portion is processed encapsulation to satisfy soil environment, increase simultaneously modulate circuit and the signal of temperature sensor is become send, finally be connected to data acquisition instrument to obtain the soil moisture.Utilize infrared non-contact measurement temperature convenient, but the precision low cost is higher, and can only measures soil surface temperature; Soil moisture measuring sonde mostly adopts the stainless-steel tube encapsulation, and concrete measurement is all that point is measured, and long metal tube is because conduction of heat causes accuracy of measurement not high.The sensor change send device much can not satisfy open-air environment for use, is applied to soil moisture measurement at aspects such as leakproofness, sense temperature compensation and has certain defective.And soil layer fathoms and controls general in-site measurement, the complex operation of passing through.
The utility model content:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of soil moisture pick-up unit, and precision is high, and good reliability is produced debugging convenient, and good extendability is arranged.
Above-mentioned purpose realizes by following technical scheme:
Soil moisture pick-up unit, comprise the probe pipe that heat-conducting metal steel pipe and heat insulation pvc pipe space nest together, mounting temperature sensor inside the heat-conducting metal steel pipe part of described probe pipe, described temperature sensor connects analog to digital conversion circuit, described analog to digital conversion circuit connects master controller, and described master controller connects display.
Described soil moisture pick-up unit, described master controller adopts C8051F330.
Beneficial effect:
1. the utility model adopts the probe pipe that heat-conducting metal steel pipe and heat insulation pvc pipe space nest together, effectively avoided mutually conducting heat on the impact of measurement result accuracy between the metal probe pipe, accuracy for the soil moisture of measuring different depth plays a good role, measurement result is accurate, and measuring method is simple.
2. master controller of the present utility model adopts C8051F330, and its speed is compared with standard 8051 and improved a lot, and its peak value processing speed can reach 25MIPS, extensibility is strong, and the system works frequency that it is higher, minimum encapsulation can be satisfied the needs that design portable product.
Description of drawings:
Fig. 1, structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1:
Soil moisture pick-up unit, comprise the probe pipe that heat-conducting metal steel pipe 1 and heat insulation pvc pipe 2 spaces nest together, mounting temperature sensor 3 inside the heat-conducting metal steel pipe part of described probe pipe, described temperature sensor connects analog to digital conversion circuit 4, described analog to digital conversion circuit connects master controller 5, and described master controller connects display 6.
Embodiment 2:
The difference of the present embodiment and embodiment 1 is: described master controller adopts C8051F330.
By above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.Unaccomplished matter of the present utility model belongs to those skilled in the art's common practise.
Claims (2)
1. soil moisture pick-up unit, it is characterized in that: comprise the probe pipe that heat-conducting metal steel pipe and heat insulation pvc pipe space nest together, mounting temperature sensor inside the heat-conducting metal steel pipe part of described probe pipe, described temperature sensor connects analog to digital conversion circuit, described analog to digital conversion circuit connects master controller, and described master controller connects display.
2. soil moisture pick-up unit according to claim 1, is characterized in that: described master controller employing C8051F330.
