Accompanying drawing explanation
Fig. 1 is this utility model structural representation。
In figure: photodiode 1；Pencil output optical fibre 2；Soil 3；Light emitting diode 4；Pencil input optical fibre 5；Probe 6。
Detailed description of the invention
Below in conjunction with accompanying drawing, by detailed description below, to be more clearly understood that the above and other purpose of the invention, feature and advantage。Hereinafter, the preferred embodiment of the invention will be described in detail with reference to the accompanying drawings。
As it is shown in figure 1, a kind of soil 3 in the invention preferred embodiment detects light channel structure, including: light emitting diode 4, probe 6 and photodiode 1。
Described light emitting diode 4 is positioned at pencil input optical fibre 5 incidence end, and it passes through a connected light source driving circuit driven for emitting lights；Described light emitting diode 4 has 7 wave bands, and it is used for launching optical signal source and soil 3 is detected。
Herein, light emitting diode 4 and light source driving circuit are located in optical fiber input end by screw type fittings, thus ensure that the seal of light source；
Herein, described light emitting diode 4 and light source driving circuit are located in a box, on the fixing detector pole being connected with probe of this box。
Described photodiode 1 is positioned at the receiving terminal of a pencil output optical fibre 2, and it connects a microprocessor, and it is for being converted into the signal of telecommunication for microprocessor processes by the optical signal source that the soil 3 of reception reflects；
Herein, an amplifying circuit and filter circuit are set between described microprocessor and photodiode 1 such that it is able to the faint current signal that described photodiode 1 changes into is converted into voltage signal, and the noise signal in signal is removed。
Described pencil input optical fibre 5 and pencil output optical fibre 2 are in Y type；It is provided with described probe 6 between the two, the optical signal that the light emitting diode 4 that this probe 6 reflects for detecting soil 3 sends, and give photodiode 1 by described pencil output optical fibre 2。
When described probe 6 works, being placed in soil 3 degree of depth is 30 centimetres。
This utility model delicate structure, light source and transmission means are reasonable, have low-power consumption, narrow bandwidth, low-loss and portable。
Although the preferred embodiment of the invention is open at this for illustrative purpose, but those skilled in the art is to be understood that, under the premise of the scope and spirit created without departing substantially from affiliated claim present invention disclosed, various amendments, increase and adulterium are all possible, it is to be noted that within the interest field that above-mentioned various amendments, increase and adulterium under the premise without departing substantially from the invention scope and spirit all should be encompassed in the invention。
