| The system of Remote Ground Sensors is an effective way to obtain information of the field. This paper focus on how to form a RGS system which including vibration sensors, infrared sensors, sound sensors and image sensors.In general, two topics are discussed in this paper:1. Vibration sensors, infrared sensors, sound sensors and corresponding signal processing. These sensors make up of a network for signal detection, muti-step transmission is used to transmit the signal, and self-examination is a useful function for each unit.2. Video signal processing. B/W video signal collection and compression are mainly discussed. DSP and special integrated circuit are used to accomplish video compression of JPEG2000 standard, and CPLD is used to make the system more reliable and more compact. |
