Yu Zhiming ?Adult Education College of Nanjing Information Engineering University, Lightning Protection and Technical, Nanjing 210044 ? Abstract: In recent years, almost all the meteorological stations have built up automatic weather stations. This makes the transmission of data through network come true. The advanced equipment such as computers which have less capacity to withstand over-voltage is easy to suffer from the hazard of the lightning. According to the relevant national lightning protection technical specifications, this article introduces the basic meteorological station’s field, the equipment design of the office building connecting to the ground and the method of bonding both of them; The protective measures to the meteorological fields and the office buildings about the lightning; The comprehensive lightning protection system about power supply system and the information system. Seeking access to decreasing the rate of the meteorological station being struck by lightning through the comprehensive technology such as the adoption of flash, streaming and other potential connections, common grounding system, shielding, electrical surge protection, rational layout the lines, being isolating and so on. These will ensure th
