Solar energy is renewable energy which can be used in the drying of agricultural and sideline products. The lower computer measurement and control subsystem is designed and the improved binary table lookup algorithm is designed to realize the tank water temperature detection. The main program flow is demonstrated, furthermore, the host computer monitoring subsystem is constructed, in which the system...
Solar energy is renewable energy which can be used in the drying. From the view of agricultural and sideline products dry demand, a solar dry device designed using solar energy is demonstrated. The drying principle of the device and its mechanical structure are focused on, as well as the circuit hardware is also designed. The drying result using of this device for agricultural and sideline products...
We report a temperature-insensitive microdisplacement sensor with a locally bent microfiber taper interferometer. The microfiber taper waist diameter can be optimized to minimize the spectral shift of the sensor owing to the environmental temperature change. With a -diameter microfiber taper, a bimodal fiber interferometer is proposed and experimentally fabricated. The transmission...
Ground source Heat Pump(GSHP) is becoming the more and more focus of the world's attention as a HVAC technique of energy saving and environment protection. This paper first introduced the experiment for Ground-Source water/water Heat Pump. The heat transfer model of underground heat exchanger was introduced, and established predication modeling using neural network. From the computer simulation results,...
Nano-scale HRI liquid crystal (LC) coatings are evenly smeared along long period gratings (LPGs). Experimental results show that the transition between cladding modes and overlay modes occurs when the refractive index of the LC layer is changed from 1.477 to 1.515 by increasing temperature. The sensitivity enhancement to HRI in the transition region is approximately 6 times the sensitivity outside...
This paper presents some key issues in fiber-optic interferometric magnetic field sensors. Practically applicable methods to design and implement fiber-optic Michelson interferometer and transducers are described with experimental verifications. Detection scheme of traditional hardware demodulation is improved, and a new software demodulation method is addressed. Transducers were implemented by using...
