A superhydrophilic thick-film pH sensor based on chemical etching, and a preparation method thereof are provided. The superhydrophilic thick-film pH sensor includes: a substrate, and a working electrode and a reference electrode that cover surfaces of the substrate. The working electrode includes a titanium sheet attached to one side of the substrate; a front part of an outer surface of the titanium sheet is covered with a titanium dioxide sensitive layer; an electrically-conductive layer is attached to the other side of the substrate; the reference electrode is located on the electrically-conductive layer, and a surface of the reference electrode is coated with a naphthol layer; and an insulating gel wraps the substrate to expose only the working electrode and the reference electrode. The working electrode is obtained by soaking the titanium sheet in an 80° C. NaOH solution, and is integrated with the reference electrode to produce the thick-film pH sensor.

This invention relates to control method and apparatus of wind machine for plant frost protection, and belongs to the domain of agro-meteorological disaster monitoring and control. Existing wind machines for plant frost protection only rely on critical damage temperature or wind speed as a condition to start. If there is no thermal inversion, operation of the wind machine will aggravate freezing injury to plants. If the strength of thermal inversion is weak, the effect will be minimal. The feature of this invention is that when temperature at the plant canopy is lower than the critical damage temperature of a certain plant and temperature difference between the top and bottom of the thermal inversion layers exceeds set threshold, wind machine will start automatically. Otherwise it will remain off. The control apparatus mainly consists of sensorat the top of thermal inversion layer, sensorat bottom of thermal inversion layer, and controller. This invention of the control of frost protection wind machine ensures rational and effective operation and avoids aggravated freezing risk due to misuse of energy and incorrect operation.
