Abstract


With the rise and expansion of a large number of industrial and mining enterprises , there will be more and more waste water and sewage discharged into the environment , especially in the Pearl River Delta region , this phenomenon is particularly prominent . There have been serious pollution in the Pearl River Basin water resources , and the resulting environmental pollution and ecological pollution has caused the local authorities attach great importance to . To this end , this project cooperation with Guangdong dean Microelectronics , to develop a versatile sources of water pollution monitoring network voice alarm information through real-time fast source of pollution detection , voice alarm and stored sources of pollution information . The alarm function is to receive signals to by the front end the Beidou communication processor transmission sources corresponding to the voice alarm . The alarm design selection is currently popular in the field of industrial control ARM chip LPC2368 as the main controller, using the the RS232/RS485 universal means of communication to the completion of the acquisition and processing of information on the sources of water pollution ; choose SD card as the storage medium of voice files and sources of pollution information storage ; voice alarm use cheap WAV and MP3 decoder chip VS1003 voice file decoding . Also designed to extend the voice output channels , to improve the scalability and flexibility of the system . The alarm design compatible with both FAT16 and FAT32 file system format , and support voice files in WAV and MP3 are two types of alarm , compared to water pollution monitoring system alarm , the alarm has greater versatility and flexibility. The alarm in the software design in embedded real-time microkernel operating system uC / OS- II , which makes the alarms in real time greatly improve and enhance effective solution based on the front and back office software system alarm in alarm occurs when voice playback is not continuous . The alarm is part of the Pearl River waters Beidou monitoring demonstration project \
