Description
Technical Field
The invention relates to the field of termite control, in particular to a termite detection system and a termite detection method.
Background
Termites are one of insects which can efficiently degrade lignocellulose and exist in the natural environment, belong to the phylum arthropoda, class insecta, subclass pteroidea and general order reticuloptera, and are semi-metamorphosis completely social insects. In human society, termites can damage house buildings, particularly brick-wood structures and wood-structure buildings, and the termites are hidden in the wood structures to damage or damage bearing points of the wood structures, so that the houses are collapsed suddenly, and huge loss is caused.
In order to detect the existence of termites and then control and kill the termites as early as possible, there are various termite detection devices that can detect the existence of termites.
For example, a device disclosed in japanese unexamined patent application publication No. h7-255344, which can detect vibration generated when termites eat a substance such as a piece of wood for detection, is provided in a probe body of the device with: means for positioning a substance constituting a food intended for termites proximate to a termite infestation path; and a detecting device that detects vibration generated by the termites eating food or by their activities. More specifically, the termite detector disclosed in this application includes: a detector outer frame; a battery as a power source; a vibration detector for detecting vibration; a signal processing circuit for amplifying and processing the signal from the vibration detector; a rod for transmitting the vibration to the vibration detector; wood material as bait for termites; a spring for holding the wooden material in contact with the rod; a bait disc and a detector bottom. However, this device has many factors that affect the use of the device, and it is difficult to determine whether or not the vibration is caused by termites or the vibration due to the passage of a vehicle, and it is difficult to accurately determine the presence or absence of termites.
A termite detection device disclosed in patent No. CN1115955C, comprising: a box placed under the floor or at a certain position around the house and having an opening portion at a lower end thereof; the first attractant part extends out of the opening part of the box with a certain range and is provided with a group of inducing holes with lower openings; an electrical detection portion provided above the first adsorbent member with a first hole communicating with the induction hole and second holes intersecting the first holes, a transmission element and a reception element being provided on each of the second holes so as to be opposed to each other across one of the first holes; the termite detection device further includes: a second attractant member provided at one of the electric detection portions; a sealing member sealing an area between the cartridge and the first getter member; and actual trace detection means, provided between said first attractant means and said electrical detection portion, for detecting the actual trace of termite infestation, the actual trace detection means being a film that can attract termites to gnaw. Which alters the signal to the receiving element by termites eating through the membrane and blocking the signal from the emitting element, enabling electrical detection of termite infestation. However, the detection device is difficult to detect the termites in the early stage, and the structure is very complicated and fine, so that the device is difficult to popularize and use.
Patent No. CN106199729B discloses a termite detection device and a termite detection method, wherein the device comprises: the bait strip is provided with a circuit board and a detection switch; the bait strip is internally provided with a deep hole which is internally filled with a liftable support body, and under normal conditions, the top of the support body supports a detected body to ensure that the detected body is positioned in the detection range of the detection switch, and the detection switch is in a conducting state; when the deep hole is bitten by termites, the top of the support body descends to enable the detected body to descend and exceed the detection range of the detection switch, and the detection switch is in an off state; the circuit board is electrically connected with the detection switch and used for judging the on-off state of the detection switch. The method comprises the following steps: and judging whether the termites exist or not according to the on-off of the detection switch. When the deep hole is bitten through by termites, the top magnetic steel and the middle magnetic steel turn over, the middle magnetic steel is attracted to the bottom of the deep hole by the bottom magnetic steel, the top magnetic steel is attracted to the bottom of the deep hole by the middle magnetic steel, and a detected body supported by the top magnetic steel exceeds the detection range of the detection switch to achieve the detection effect. However, the structure needs to wait for the termite to bite through before the existence of the termite can be detected, and in the actual use process, the termite is discovered to have a relatively long breeding process when the termite is detected, so that the termite can not be detected in an early stage.
The above devices all have the problem that termite detection is difficult to carry out in the early period, and at the same time, when studying the habits of the termites, the inventor finds that materials such as excrement, soil, debris, residues and the like of the termites are bonded into mud lines and mud quilts through saliva secreted by the termites during the life activities of the termites, the mud quilts are used as temporary covers of the reciprocating passages or feeding activities of the termites, the mud quilting behaviors of the termites are in the early feeding stage, if the detection of the termites can be completed through the detection of the mud quilts, the existence of the termites can be found in the early stage, therefore, how to detect whether the termites exist or not through the characteristics of the mud quilts is the problem which needs to be solved at present.

target: the method is used for quickly acquiring the partial pressure data (embodying the resistance value). Experiments have verified that the charging time T of the rc hybrid of the mixture is suitably 0.6 seconds, and it is used to determine the classic sampling value of termites (10 samples in 0.6 seconds, and 9 corresponding log values are (as an array L) regardless of the first value:
0.693147,1.098612,1.386294,1.609438,1.791759,1.94591,2.079442,2.197225,2.302585, and the average of the array is: ln is 1.678268.

and starting the collector, acquiring the partial pressure data at intervals of 0.06 second, and continuously sampling for 10 times for 0.6 second.
The initial value V0 is used as a basic reference value and does not participate in the operation.
Comparing the sampled data one by one through the above mentioned arrays, and obtaining a deviation value N by using a simple subtraction method; i.e. for the x-th sample value (Vx), the resulting value is: nx ═ V (Vx-V0)/Lx
Summing the 9 deviation values and then calculating the average value (considering that the operation unit is MCU and the actual test result, no high order variance operation is needed), the simple arithmetic average value can obtain the sufficiently clear deviation.

when V0 was less than 200mV (empirical value), termite was considered absent as negligible error.
When V0>600mV, A is checked.
When a/Ln is greater than 0.5, the overall deviation is large, and at this time, communication due to other causes is considered, and at this time, conduction due to sporadic water droplet aggregation is empirically determined.
When A/Ln is less than 0.5, the alarm is considered to be effective, and according to the configuration of the system, the monitoring point is marked as a yellow alarm, namely suspected termite.
And when the second reported data is still A/Ln <0.5, converting to red alarm, namely reporting that the termites exist. (according to the experimental case, the closer the sampled data is to the classical value, the closer the A/Ln is to 0, as the number of termites increases).
