Description
Technical field
The present invention relates to a kind of soil information satellite positioning surveys instrument, be used for the space distribution of the quick measured soil information relevant with plant growth.
Background technology
The factor that influences plant growth has a variety of, and as the type of soil, water percentage, pH value, conductivity, N-P-K content, the content of organic matter, disease and pest etc., the distribution of these information in the farmland is uneven, has room and time difference.Obtain the distribution situation of soil information, implement management such as variable fertilization, spray medicine according to the situation of crop reality targetedly, can reach and reduce the purpose that drops into, improves output, reduces environmental pollution.In order to obtain the distribution situation of soil information, need to measure the position and the relevant soil information of sampled point.Traditional metering system and instrument are difficult to satisfy the requirement of location survey fast in the precision agriculture management, and traditional surveying instrument does not possess the function of location on the one hand, can only utilize other modes such as tape measure, total powerstation to wait and measure sampling point position, and efficient is too low; Traditional on the other hand soil information is measured to be needed to carry out in the laboratory, use specialized equipment, measuring period is long, can not measure real-time, need in lab oven at, carry out as the traditional measurement soil water content, through dry, weigh, oven dry again, till the quality of weighing for twice is almost completely equal.
Summary of the invention
In order to overcome the problem that can not position sampled point, the purpose of this invention is to provide a kind of soil information satellite positioning surveys instrument, can be fast measured soil information (as soil moisture content, pH value, conductivity etc.) in real time, has higher measuring accuracy, the positional information of sampled point can be provided simultaneously in real time, thereby obtain the space distribution situation of soil information.
The technical solution used in the present invention is that it comprises:
1) receiver of Global Positioning System (GPS) is connected with single-chip microcomputer by RS-232 interface;
2) sensor is connected with single-chip microcomputer by the A/D analog to digital conversion circuit;
3) be connected to keyboard on the single-chip microcomputer of measuring instrument, latch, display, data-carrier store and power supply, the receiver of said Global Positioning System (GPS) are hand-held set GPS310 or are built in measuring instrument inside with the OEM plate.
Said single-chip microcomputer is 89C52, and keyboard is 4 * 4 ranks keyboards, and latch is the ternary latch of 74HC573, and display is a YXD1602 character formula LCDs, and data-carrier store is HM626.
This instrument is made up of measuring instrument, GPS (Global Positioning System (GPS)) receiver and sensor, by the position of GPS measurement sampled point, by the quick measured soil information of sensor (as water percentage, pH value, conductivity, nutrient etc.).Measuring instrument is made up of mainboard, membrane keyboard and LCD display etc., and keyboard adopts 4 * 4 ranks keyboards, is connected to mainboard by flat wire, and display adopts YXD1602 character formula LCD, is connected to mainboard by data line.At the meter case rear portion three connectors are arranged, connect battery feed, GPS receiver and sensor respectively.Gps receiver links to each other with single-chip microcomputer (89C52) by RS-232 interface, is isolated locator datas such as precision, latitude, height by single-chip microcomputer.The signal of sensor (moisture transducer, pH sensor etc.) is sent into the A/D module (being made of AD0809) of measuring instrument, can connect 8 road signals simultaneously, converts sensor signal to digital quantity under the control of single-chip microcomputer.Single-chip microcomputer is presented at locator data and soil information on the LCD display in real time, by the keyboard input of control commands, can realize the function such as storage, demonstration, deletion, area distance calculation, on-line communication of data.During use, sensor is inserted in the soil, the GPS receiver is placed on the top of measurement point, press " measurement " key of measuring instrument, begin to measure, behind signal stabilization, by " storage " key storage data, move on to other position then and measure,, generally evenly choose measurement point by the grid mode for the distribution of true reflection soil information.
The present invention compares with background technology, has following characteristics:
(1) positioning function: this instrument application the GPS technology, when measuring, can provide the three dimensional local information of sampled point fast in the field;
(2) measure fast in real time: measuring instrument uses the information of sensor measurement soil, test speed is fast, measuring accuracy is high, easy to use, can measure in real time; A whole set of testing tool a people just can carry, as long as be with this cover tester to the field, just can record agricultural land information in real time, and directly be presented on the display screen with digital mode, or these information are deposited in the chip of testing tool, also can realize simultaneously the communication of computing machine so that handle afterwards;
(3) simple in structure, function is strong, is easy to carry: a whole set of detector only is made up of sensor, GPS, single-chip microcomputer, keyboard, display screen, lead etc., in light weight, this instrument also has the GIS function except having function such as quick assignment test, can calculate farmland area and realize map storage etc.;
(4) have good social benefit and economic benefit: by using the quick assignment test instrument of agricultural land information, can solve the current problem of obtaining the agricultural land information difficulty, to improving farmland management, farmland decision-making, realizing that precision agriculture plays a positive role.
