This paper introduces a new scheme of remote automatic meter reading device based on embedded Linux operating system,which adopts high-performance 32-bit CPU(MPC860T),advanced radio communication modules and uses general packet radio service (GPRS)as data transmission platform,thus realizing efficient kWh meter reading and seamless data fusion with Internet and improving the technical level of kWh meter reading.
After annealing, its parameters are as follows: Resistance R=100±0.2Ω, resistance temperature coefficient a=(6170±30)×10~(-6), temperature range of working T=-40~150℃, lincarity=0.7%(betwccn 0~100℃), and sizc=φ8 ×80mm.
According to the objective of electricity market opening on generation side in China. the characteristics and configuration of electricity marketplace operation management and dispatching system are analysed in this paper. Based on the present situation of power industry and application level of computer and communication technologies in China.
Our estimates show that the present-day technical level with laser power of about 1 W provides sufficient sensitivity for detecting gravitational waves.
On a technical level, the authors describe the mirror's function in the painting of self-portraits and recommend it be used to draw foreshortened objects more easily and to judge the quality of finished paintings.
Most of FDI in China was from the developing countries and regions, which had a negative effect on the size and technical level of foreign capital enterprises.
The key to solving these problems is to enhance the scientific and technical level of monitoring, management, and restoration of water resources and associated water and soil components of local ecosystems.
