Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without any creative efforts belong to the protection scope of the embodiments of the present invention.

Aiming at the problems of high cost, poor feasibility and the like in the prior art, the embodiment of the invention utilizes the electromagnetic inner edge impedance sensor to measure and extract four key parameters of the water content of the stem of the target arbor so as to represent the life vitality of the arbor, compares each parameter with a standard value obtained through historical statistics, and estimates the life vitality of the arbor. Embodiments of the present invention will be described and illustrated with reference to various embodiments.

Fig. 1 is a schematic flow chart of a method for performing real-time nondestructive evaluation on life vitality of trees according to an embodiment of the present invention, as shown in fig. 1, the method includes:

s101, obtaining the stem water content of the target arbor by using an electromagnetic inner edge impedance sensor, filtering the stem water content, and obtaining a filtered stem water content data set.

It can be understood that in order to overcome the problems of plant life activity evaluation by measuring net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO2 concentration, the embodiment of the invention adopts a real-time nondestructive measurement of the stem water content of the arbor and a measurement result analysis mode to realize evaluation. Therefore, in the embodiment of the invention, the moisture content of the stem of the target arbor is firstly measured, and the measurement is realized by using the electromagnetic inner edge impedance sensor. Wherein optionally, the output value of edge impedance sensor inside the electromagnetism is gathered to specific accessible microenvironment monitoring station and is obtained the stem moisture content. The real-time and non-destructive measurement of the moisture content of the arbor stem can be realized through a novel electromagnetic inner edge impedance sensor.

And then, combining the stem water content data with the signal characteristics of the microenvironment parameter set and the like, carrying out filtering processing on the obtained stem water content according to a given filtering mode so as to filter out certain fluctuation caused by the influence of other environmental factors and the characteristics of the sensor in the acquisition process of the stem water content data, thereby eliminating certain influence on subsequent data processing, finally obtaining data after filtering and forming a filtered stem water content data set according to the certain influence.

And S102, respectively obtaining the daily minimum stem water content, the daily maximum stem water content, the average stem water content and the stem water content range of the target arbor by analyzing the filtered stem water content data set.

It can be understood that on the basis of the filtered stem water content data set obtained through filtering, statistical analysis is performed on data in the data set to obtain statistical parameters with one day as a period, namely the minimum stem water content and the daily maximum stem water content, and further calculation is performed to obtain a stem water content average value and a stem water content range.

S103, comparing the daily minimum stem water content, the daily maximum stem water content, the average stem water content and the stem water content range with preset standard values respectively, and evaluating the life vitality of the target arbor.

It can be understood that, in the embodiment of the present invention, finally, through analysis of the measured parameters related to the moisture content of the stem of the target arbor, the change rule and the change trend of the parameters are obtained, and the life activity of the target arbor is further evaluated on the basis. Specifically, according to healthy trees which are in the same period with the target tree and have the same tree species and the same breast diameter, measurement of corresponding parameters (including daily minimum stem moisture content, daily maximum stem moisture content, average stem moisture content and stem moisture content range) is performed in advance, and corresponding parameters of all healthy trees are averaged to obtain a preset standard value. When the evaluation application is carried out, parameters related to the moisture content of each stem measured according to the target arbor are compared with a preset standard value item by item to obtain the change rule and the change trend of the parameters of the target arbor, and the life activity of the target arbor is further evaluated on the basis. It is understood that the healthy trees therein mean trees free of plant diseases and insect pests and dead branches, and whose growth conditions satisfy certain criteria.

According to the method for evaluating the life vitality of the arbor in a real-time and nondestructive mode, the life vitality of the arbor is represented by measuring and extracting four key parameters of the water content of the stem of the target arbor by using the electromagnetic inner edge impedance sensor, and the life vitality of the arbor is estimated by comparing each parameter with a standard value obtained through historical statistics.

The electromagnetic inner edge impedance sensor specifically adopts a 100MHz signal source, and the generated electromagnetic wave signal is reflected at the connection part of the transmission line and the adjustable bimetal ring probe due to impedance mismatching, so that the reflected signal wave and the incident signal wave meet and overlap on the transmission line to form a standing wave.

Correspondingly, utilize electromagnetism internal edge impedance sensor, the step of the stem moisture content of obtaining target arbor specifically includes: and detecting the voltage difference of the two ends of the transmission line, and calculating the moisture content of the stems based on the voltage difference.

It can be understood that the embodiment of the invention specifically adopts an electromagnetic inner edge impedance sensor developed based on the standing wave rate principle to measure the moisture content of the stems. The electromagnetic inner edge impedance sensor adopts a 100MHz signal source, electromagnetic wave signals generated by the electromagnetic inner edge impedance sensor are subjected to signal reflection at the joint of a transmission line and an adjustable bimetal ring probe due to impedance mismatching, and reflected signal waves and incident signal waves meet and are superposed on the transmission line to form standing waves. Through detecting the voltage difference at the two ends of the transmission line and carrying out calculation based on measurement calibration by the voltage difference, the moisture content of the arbor stem can be indirectly obtained.

Optionally, according to the foregoing embodiments, the step of performing filtering processing on the moisture content of the stems specifically includes: and for all the stem water contents, starting from any stem water content, establishing a filtering window with the length of an odd number K by taking any stem water content as a center, removing the maximum value and the minimum value of any stem water content in the filtering window by adopting a median average filtering method, and solving the arithmetic mean of the residual K-2 values as a filtered output value until all the stem water contents are traversed.

It can be understood that, in the embodiment of the present invention, the median average filtering method is adopted to perform filtering processing on the moisture content of the stems, so as to obtain the filtered data set of the moisture content of the stems. Specifically, referring to fig. 2, a schematic flow chart of performing filtering processing on the moisture content of the stems in the real-time nondestructive evaluation method for the life vitality of the arbor provided by the embodiment of the present invention includes the following processing steps:

and step 1, adopting a median average filtering method to establish a filtering window with the length of K (K is an odd number) by taking the pre-filtering point as a center for any stem water content, namely any pre-filtering point.

And step 2, removing the maximum value and the minimum value in the filtering window, and solving the arithmetic mean value of the residual K-2 values as an output value after filtering.

And 3, judging whether the current pre-filtering point is the last point in the stem moisture content data set, if not, moving to the next pre-filtering point, taking the next pre-filtering point as any new pre-filtering point, turning to the step 1, if so, finishing filtering, and outputting the filtered stem moisture content data set.

It will be appreciated that mean filtering is a typical linear filtering method that focuses on this sampling period. In a sampling period, sampling the signal for k times, and taking the arithmetic average value as the filter output in the sampling period. The mean filtering has a good suppression effect on the periodic interference signal, but generates a certain delay, which is proportional to the number k of samples required for filtering. The k value depends on the requirements for smoothness and sensitivity. k increases, smoothness increases, and sensitivity decreases.

Median filtering is a typical nonlinear filtering method, and is often used to filter out accidental impulse interference. The median filtering sorts the sampling values of the signal for k times continuously, and takes the median as the filtering output in the sampling period. The larger k the better the filtering effect, but the delay increases. The median filtering has good filtering effect on the impulse interference in the slowly changing process.

However, the sampling filtering methods have the defects of low speed, large influence of threshold selection and the like, so that a median average filtering method is adopted by combining the moisture content of the stems and the signal characteristics of the microenvironment parameter set.

Optionally according to the above embodiments, the step of analyzing the filtered data set of the moisture content of the stems specifically includes: and taking one day as a period, respectively counting each data in the filtered stem water content data set, obtaining the daily minimum stem water content and the daily maximum stem water content, and further calculating the stem water content average value and the stem water content range.

It can be understood that the embodiment of the invention statistically analyzes the filtered data set of the moisture content of the stems to obtain a plurality of parameters related to the moisture content of the stems. Specifically, the time of one day is taken as a period, the stem moisture content data in the filtered stem moisture content data set is analyzed, the daily minimum value and the daily maximum value of the stem moisture content, namely the daily minimum stem moisture content and the daily maximum stem moisture content, are counted, and meanwhile, the stem moisture content average value can be calculated according to all the stem moisture content data. On the basis, the range of the moisture content of the stems can be determined. In addition, the change condition of the life activity parameters of the trees can be summarized according to the counted parameters.

Specifically, referring to fig. 3, a schematic flow chart of extracting parameters related to the moisture content of the stems in the real-time nondestructive evaluation method for the life vitality of the arbor provided by the embodiment of the present invention includes the following steps:

firstly, reading a filtered data set of the moisture content of the stems;

secondly, dividing the data of the moisture content of the stems by taking one day as a unit;

thirdly, sorting the data of the moisture content of the stems in one day to obtain a daily maximum value and a daily minimum value;

and finally, calculating the daily average value and the range value of the moisture content of the stems.

Optionally, according to the above embodiments, the step of evaluating the life activity of the target arbor specifically includes: comparing the daily minimum stem water content, the daily maximum stem water content, the average stem water content and the stem water content range with preset standard values item by item, analyzing the change rule and the change trend of the daily minimum stem water content, the daily maximum stem water content, the average stem water content and the stem water content range, and evaluating the life vitality of the target arbor based on the change rule and the change trend.

It can be understood that, in the embodiment of the invention, through analysis of the measured parameters related to the moisture content of the stem of the target arbor, the change rule and the change trend of the parameters are obtained, and the life activity of the target arbor is further evaluated on the basis. Specifically, parameters related to the moisture content of each stem measured according to the target arbor (including daily minimum stem moisture content, daily maximum stem moisture content, average stem moisture content and stem moisture content range) are compared with parameters related to the moisture content of each corresponding standard stem in a preset standard value item by item to obtain a change rule and a change trend of the parameters of the target arbor, and the life activity of the target arbor is further evaluated according to the change rule and the change trend.

Optionally, the preset standard value may be obtained by averaging corresponding parameters of a sample tree, where the sample tree is a healthy tree that is in the same region and has the same tree species and the same breast-height diameter as the target tree.

To further illustrate the technical solutions of the embodiments of the present invention, the embodiments of the present invention provide the following specific processing flows according to the above embodiments, but do not limit the scope of the embodiments of the present invention.
