Abstract
The utility model relates to a trees diameter growth automatic recorder, including the shell, measure the sheetmetal, capacitive gate transducer, the motor, the singlechip, wireless transmission module constitutes. Measuring sheetmetal one end and fixing on the shell, the stiff end that the sheetmetal was followed to annular of other end coiled passes through capacitive gate transducer, links to each other with the motor, capacitive gate transducer, the motor, the singlechip, wireless transmission module is located inside the shell. The measurement sheetmetal of instrument need adopt does not have the sheetmetal of bullet to reduce the error that produces in the measurement process because of the pulling, it is whole stretching in the shell outside not carrying on when the diameter is measured to measure the sheetmetal, so can not produce in close contact with with the measuring point, can not influence the normal growth of plant, makes the measured value more accurate, the instrument adopts wireless transmission module to return data transmission to the receiving terminal in real time, can increase the measuring frequency, can save the number of times of artifical contact in addition.
Description
Technical field
The utility model relates to tree diameters growth self-recording device, is applicable to periodic logging and transmits the numerical value that trees different parts diameter grows continuously, change, is beneficial to the growth rhythm of (or between Chinese rose) before research trees year border.
Background technology
The trunk of research trees (and the trees in forest) and branch growth change, for the growth rhythm of research individual plant trees, and the change of forest standing forest, succession have great significance.Have full and accurate, accurately trunk or branch continuous growth in thickness data be vital for the single wood of structure or Stand Growth Model, important theoretical foundation can be provided for forest management planning.Traditional trunk and branch diameter data are all often that the method for being resolved by stem analysis and branch is obtained, and need the normal wood chosen to cut down to intercept year wheel disc, then carry out Indoor measurement, carry out the measurement arboreal growth situation of inverse-push.This method is the main obtaining means of current forestry trees growth data.But this method is more satisfactory for asking the growth in thickness of calculating trunk, but ask calculation then not ideal for branch growth in thickness, because relative to trees, the life-span of branch wants short many, along with the change of time, the branch that on strain trees, president makes new advances, then can there is death in the branch of some bottoms, slowly come off, so this part branch growth change we then have no idea to measure.What period, trees grew the vigorous stage in 1 year was in addition, year increment and weather conditions at that time, the relation of the factors such as edaphic condition, then the method can not resolved by trees is inferred out.Therefore want the relation of understanding arboreal growth and various external factor in depth, then need to carry out long-term continuous print observational record, but use traditional method cannot complete this work.In order to carry out long-term, continuous print monitoring to tree diameters growth, special this utility model tree diameters of invention growth self-recording device.
Summary of the invention
Grow measuring method based on present tree diameters (trunk, branch diameter) and reason that is long-term, continuous print monitoring can not be carried out to tree diameters growth, special this tree diameters of invention growth self-recording device.
The utility model relates to a kind of tree diameters growth self-recording device, and comprise shell, measure sheet metal, capacitor grid transducer, motor, single-chip microcomputer, wireless transport module forms.Measuring sheet metal one end is fixed on shell, and the other end is coiled into the stiff end of an annular from sheet metal by capacitor grid transducer, is connected with motor; Capacitor grid transducer, motor, single-chip microcomputer, wireless transport module is all positioned at enclosure.The function of motor drives the ring measuring sheet metal formation expand and reduce; The function of capacitor grid transducer is the displacement that sheet metal measured in record; Single-chip microcomputer effect is the numerical value reading capacitor grid transducer; The function of wireless transport module is that the remote data that single-chip microcomputer reads is returned to receiving end.
The measurement sheet metal of this instrument need adopt without playing sheet metal, to reduce in measuring process because pulling the error of generation; Measuring sheet metal is all stretch in housing exterior when not carrying out diameter measurement, just can be drawn in enclosure by motor when measuring, measure after terminating and also can all stretch out, close contact can not be produced with measuring point like this, the normal growth of plant can not be affected, make measured value more accurate; Instrument adopts wireless transport module in real time data to be transmitted tieback receiving end, can increase the frequency of measurement, and can save the number of times of artificial contact.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the utility model structural drawing.
In figure: 1 shell, 2 measure sheet metal, 3 capacitor grid transducers, 4 motors, 5 single-chip microcomputers, 6 wireless transport modules.
Embodiment
As shown in Figure 1, tree diameters growth self-recording device, by shell (1), measures sheet metal (2), capacitor grid transducer (3), motor (4), single-chip microcomputer (5), wireless transport module composition (6).When using tree diameters growth self-recording device to carry out tree diameters measurement, during installation, sheet metal (2) will be measured and be connected one end around the part needing to measure diameter with motor (4), be connected with motor (4) through capacitor grid transducer (2), the length measuring sheet metal need reserve suitable length in advance according to tree measurement position growth tendency.When a measurement is taken, the upper measurement sheet metal be wound around of motor (4) all stretches out shell (1), capacitor grid transducer (3) carries out zero initialization, motor (4) start to tighten up measure that sheet metal (2) formed around tree ring, until can not continue to tighten up, at this moment measure sheet metal (2) and be no longer moved, capacitor grid transducer (3) reads measured value now, send single-chip microcomputer (5) to, then be sent to wireless transport module (6) by single-chip microcomputer (5), send back long-range receiving end; Finally, motor (4) again will be measured sheet metal (2) and all transfer out shell (1), and one-shot measurement terminates.Next time adopts same process to carry out duplicate measurements when measuring.
Claims (4)
1. tree diameters growth self-recording device, by shell (1), measure sheet metal (2), capacitor grid transducer (3), motor (4), single-chip microcomputer (5), wireless transport module (6) forms; It is characterized in that: measure sheet metal (2) one end and be fixed on shell (1), the other end is coiled into the stiff end of an annular from sheet metal by capacitor grid transducer (3), is connected with motor (4); Capacitor grid transducer (3), motor (4), single-chip microcomputer (5), it is inner that wireless transport module (6) is all positioned at shell (1).
2. tree diameters growth self-recording device according to claim 1, is characterized in that: the telescopic moving of measuring sheet metal (2) is controlled by motor (4).
3. tree diameters growth self-recording device according to claim 1, is characterized in that: measuring sheet metal (2) is shell (1) outside that all extends when not carrying out diameter measurement.
4. tree diameters growth self-recording device according to claim 1, is characterized in that: utilize wireless transport module (6) that capacitor grid transducer (3) measurement data real-time Transmission is returned long-range receiving end.
