Field, a kind of rice field face automatic water level measurement device
Technical field
The utility model relates to field, a kind of rice field face automatic water level measurement device.
Background technology
The variation of field, rice field face water water level is the important indicator of determining Suitable irrigation amount and irrigation time, field, Accurate Measurement rice field face water SEA LEVEL VARIATION is significant to the nutrient loss that calculates rice field water balance and estimation rice field rainwash and cause, but at present measurement of correlation device and instrument shortage, researcher utilizes original method namely to place ruler as field face water SEA LEVEL VARIATION determinator in the face of field mostly, although this method is simple, but comparatively extensive, automatically record, can't the Real Time Monitoring SEA LEVEL VARIATION, hand labor intensity is large simultaneously, be subjected to the impact of external environment also larger, precision is lower.
Field, existing rice field face aquametry device, owing to need staff's continuous monitoring during the observation, comparatively time-consuming, there is observational error between the different observation personnel simultaneously, because being subjected to external environment influence larger, have a strong impact on the accuracy of test observation data in addition.
The utility model content
The purpose of this utility model provides a kind of cheap, field, rice field face automatic water level measurement device that automaticity is high, can alleviate observation personnel's labour intensity.
Field, a kind of rice field face automatic water level measurement device, its special feature is: the measuring tube that comprises face below, field, partial insertion rice field, above this measuring tube, lid is installed, and the tube wall of the measuring tube above the face of field, rice field has permeable hole, thereby make the inside and outside water level of measuring tube identical; Also comprise fixedly all-in-one-piece host box and probe pipe, this probe pipe stretches in the measuring tube until face position, field, rice field from the throughhole portions on the aforementioned lid; Microprocessor wherein is installed in host box, thereby this microprocessor water-level probe interior with being installed in the probe pipe is electrically connected the collection water level information, this microprocessor also is electrically connected with accumulator and storer respectively.
Wherein measuring tube adopts pvc pipe.
Wherein the measuring tube at face place, field, rice field is set with fixedly cage plate.
Wherein microprocessor adopts single-chip microcomputer.
Wherein storer adopts USB flash disk.
Automatic water level measurement device processing of the present utility model is simple, and the field is embedding, and the automaticity of this automatic water level measurement device is very high fast, as long as power supply is sufficient, without any need for operation.The lid of device for opening during each observation can be seen the real time data of water level, changes USB flash disk, can be automatically record again, the USB flash disk data are reproducible puts mapping etc. in order to computer, degree of accuracy is higher, has greatly alleviated observation personnel's labour intensity.And can not affect crop-planting in the residential quarter simultaneously at a plurality of observation subdistrict embedded sets, embedding can for years use the once, measurement effect is good.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is field, a kind of rice field face automatic water level measurement device, the measuring tube 4 that comprises face below, field, partial insertion rice field, above this measuring tube 4, lid 8 is installed, and the tube wall of the measuring tube 4 above the face of field, rice field has permeable hole 3, thereby makes the inside and outside water level of measuring tube 4 identical; Also comprise fixedly all-in-one-piece host box 5 and probe pipe 1, this probe pipe 1 stretches in the measuring tube 4 until face position, field, rice field from the throughhole portions on the aforementioned lid 8; Wherein in host box 5 microprocessor is installed, thereby this microprocessor is electrically connected the collection water level information with being installed in the water-level probe 6 of managing in 1 of popping one's head in, this microprocessor also is electrically connected with 12V accumulator and storer respectively.
Wherein measuring tube 4 adopts pvc pipe, and the measuring tube 4 at face place, field, rice field is set with fixedly cage plate 2 in addition.
Wherein microprocessor adopts single-chip microcomputer, and storer adopts USB flash disk 7.
The utility model is the pvc pipe that utilizes (the external diameter 20cm * high 70cm) of the 5mm thickness that can buy on the market, the PVC plate cutting length of side with same material is the square of 30cm, cut out the circle consistent with managing external diameter as the center of circle take square diagonal line, be fixed in the pvc pipe top and do lid, the hole of cutting 5cm in the middle of lid, in order to fixed host computer box 5 and probe pipe 1, the part of square PVC plate remainder of cutting is placed in apart from 30cm place, pvc pipe bottom, fix with special-purpose water-proof glue, cage plate is above apart from the permeable hole 3 of offering some diameter 5mm in the cage plate 30cm, allows the interior water of pvc pipe free in and out and field face water maintenance sustained height.
Consisting of of water level acquisition part:
1, with single-chip microcomputer as control center: carry out the C Programming with Pascal Language take the STC12C5A60S2 single-chip microcomputer as core, can external real-time timepiece chip, be designed with standard time clock record year, month, day, hour, min, second and equivalent water level data in the program, the temporal information when contents of program is set as regularly (frequency acquisition be per 1 hour gather once) and gathers data that water-level probe 6 detects then with collection is saved in the USB flash disk 7 and gets final product;
2, storage part: the storage part adopts general USB flash disk 7 as memory, and the size of storage capability can determine that according to the amount of capacity of USB flash disk 7 it is convenient to change;
3, water-level probe 6 test sections: the water-level probe 6 of water level detecting part adopts electric detective technology, and accuracy of detection is designed to 1mm, can satisfy the accuracy requirement of field, rice field face SEA LEVEL VARIATION Real-Time Monitoring.
