Description
Technical field
The present invention relates to a kind of root system humidity sensor for aerosol training, belong to sensor technical field.
Background technology
In modern agriculture, aerosol training technology is the planting technology in current comparatively forward position.And one of success or failure key of technique is timely for exposing aerial root system spray nutrient solution mist.Existing solution is setting one group of empirical data, and its spray time and spray intervals time are fixing, and need artificial environmentally change to change, waste time and energy out of true; If when circuit failure or other reason cause spraying in addition, more cannot notify keeper in time, when situation is serious, crop can be dead because of lack of water.
Summary of the invention
The object of the present invention is to provide a kind of root system humidity sensor being applicable to aerosol training, it can measure root system humidity, control system is according to its measured value, spraying in time in limited time under root system is in humidity, in spray process, control system judges whether to be effectively crop root spraying according to the humidity trend of sensor, if fail effective spraying, will and alarm or call fault countermeasure.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of root system humidity sensor for aerosol training, comprise casing, signal cable line is provided with on the right side of casing, double-side aluminum printed circuit board is provided with on the left of casing, double-side aluminum printed circuit board top is provided with the first copper-foil conducting electricity and the second copper-foil conducting electricity, double-side aluminum printed circuit board bottom is provided with resistance Copper Foil, and resistance Copper Foil is provided with multiple high-power chip resistor, and resistance Copper Foil and high-power chip resistor arranged outside have the anti-soda acid fluid sealant of waterproof; Electronic circuit is provided with on the right side of double-side aluminum printed circuit board; First copper-foil conducting electricity is all connected with electronic circuit with on the right side of the second copper-foil conducting electricity, is connected on the right side of electronic circuit with signal cable line.
Further, be all connected with electronic circuit on the right side of resistance Copper Foil.
Further, the first copper-foil conducting electricity and the second copper-foil conducting electricity are crisscross arranged on double-side aluminum printed circuit board top.
Further, in order to reach the object of the erosion of acid-resistance or alkaline nutrient solution, the surface gold-plating of the first copper-foil conducting electricity and the second copper-foil conducting electricity.
In this device, one side surface of double-side aluminum printed circuit board is etched into the interdigital copper-foil conducting electricity of two covers, this two covers copper-foil conducting electricity constitutes two electrodes, multiple high-power resistance is welded on the circuit of the Copper Foil composition that aluminium base surface corrosion becomes by opposite side, and the anti-soda acid sealant sealing dress of side waterproof being provided with high-power resistance protects; The other end of double-side aluminum printed circuit board is provided with a set of electronic circuit; for the treatment of the signal collected; and the signal handled well is passed on away by signal cable, this head chassis cover of electronic circuit is housed, and the anti-soda acid sealant sealing dress of same waterproof protects.Electronic circuit goes out a pair AC signal, and be carried on copper-foil conducting electricity, when there being water to be sprayed on copper-foil conducting electricity, electronic circuit can measure AC signal has significant change compared with during dry tack free, at this moment electronic circuit can output signal signal cable line, electronic circuit output voltage to high-power resistance will heat whole double-side aluminum printed circuit board simultaneously, evaporates the water on surface with the object reaching dry copper-foil conducting electricity fast.
Because water spray is a process continuing to be interrupted, such as interval minute spray water second, then second is sprayed again in interval minute, constantly repeats.In order to measure the validity of each water spray, the moisture on copper-foil conducting electricity must be evaporated timely, so devising by high-power resistance is the heating line of main element, this heating line does not work when dry tack free, only measures when there is moisture on surface and just starts.
This beneficial effect of the invention is: this contrive equipment can measure root system humidity effectively, control system is according to its measured value, spraying in time in limited time under root system is in humidity, in spray process, control system judges whether to be effectively crop root spraying according to the humidity trend of sensor, if fail effective spraying, will and alarm or call fault countermeasure.This apparatus structure is simple, low cost of manufacture, fast response time, measurement accurately, without wrong report.
