A Kind of Multifunction Data Processing Terminal Used in Underground Based on ARM11

The paper introduced a kind of intrinsic safety multifunction data processing terminal used in underground based on microprocessor chip S3C6410. It can record the underground multifunction data under the environment of whole dark (0Lux) through night-vision device, headphone, microphone etc, and achieve the multifunction frequency data´s wireless transmission and wire transmission through WiFi (Wireless Fidelity), USB technology. The low-voltage (≤3.3V) design of the system power both in conformity with the intrinsically safe demands and realize the low power consumption (3.5W) of the device. The software of the data processing terminal uses Windows CE as the platform of the embedded operating system. Especially it can be well used on mine security, saving and emergent area, having higher applied value. The experiments show that the underground multimedia data processing terminal based on ARM11 can realize the high definition display, the collection, processing, displaying, storing and transmitting of the audio data.
