This paper designed an adaptive pull-up circuit in the bus master of 1-WIRE system and a parasite power supply circuit based on voltage monitor and boot-strapped CMOS switch in the bus slave to increase the parasite power supply capability from 5μA to 1mA average and 10mA peak, and the proposed bus master was backward compliant with the traditional 1-WIRE slave devices.

In the lightning location technology research,lightning location system independent developing and the lightning detection network construction,it started early,and had good durative in China.

Combining with the China Grid Lightning Detection Network(CGLDN),this paper utilizes the latest high-speed video system with the maximum resolution of 1024 1024 pixels,the maximum frame rate of over 650,000fps,and the record time over one second to carry out .
