Study On Rolling Moment Sensor And System Of Remote Sensing

Rolling mill is the important production equipment in steel metallurgy corporation, in the steel rolling production process, the rolling moment information plays important part in ensure production safety, optimize the rolling order to achieve optimal production process automation and control. There are many sensors that can measure the roll force, including resistance strain torque sensor reliability, stability, accuracy, ease of installation and relatively well, can better adapt to the work environment of relatively poor rolling. But to use such sensors for measuring rolling moment, the sensor rotate by the shaft, so it need to settle the power supply and signal transmission problems; because of the poor installation/working conditions, the sensor signals drift more serious, so also need to settle sensor Real-time compensation/calibration, and other issues.To settle the problem of electricity supply to sensors, a-Si photovoltaic panels will be winding/fixed in the shaft, will be provided by artificial sources of light energy into electrical energy. Amorphous silicon photovoltaic panels under the spectral characteristics, select the appropriate source, and along the shaft circumference equalization, so that it can receive the sustained and stable energy and design of a dedicated power management circuits, to coordinate back-up power supply (Li-ion battery) Charge/discharge .To solve the problem sensor signal drift, and realize sensor system's install and play signal send, the sensor integrated by the X9241, AD623 and the MCU based SoC technologyt to make up the smart signal measure circuit, the output signal of sensor was magnified, filtered, A/D conversion, and use of sensor signal MCU features, real-time feedback signal drift compensation, access to digital information that torque, calibration and converted to the serial-band signal, modulation generated by the MCU 38kHz pulse of the carrier, has been generated by drive-wave infrared LED launch the corresponding pulse of light.To drive shaft torque on the information reliable transmission to the ground, so that a group of infrared LED drive shaft along the circumference uniform, uniform angle infrared LED is less than the scattering angle, simultaneously launching pulse of light, so that the signal ground Can receive treatment system for receiving and has been transferred to the corresponding wave infrared pulse of light. Signal reception processing system, will receive the pulse-demodulator/restore, to achieve a rolling moment of infrared remote sensing information.
