The invention discloses an underwater observation network control circuit which comprises a power management module, a microprocessor circuit module, a dip angle sensor unit circuit, an analog signal multiplexing modulation circuit unit, a SD card storage circuit unit, a universal asynchronous receiver and transmitter (UART) interface circuit unit and a JLINK debugging circuit unit. The power management module comprises a 5V power-switching circuit, a 5V switching + / -12V power-switching circuit and a 3.3V power-switching circuit. The underwater observation network control circuit is strong in equipment communication expansion capability, high in transmission speed and strong in real-time performance due to the fact that five UART serial ports including a complementary metal-oxide-semiconductor transistor (CMOS) level and a recommend standard 232(RS 232) level. Different nodes are in wireless communication through Zigbee, so the underwater observation network control circuit is big in network capacity, capable of supporting research requirements for large-scale water areas, low in equipment power consumption, strong in environmental suitability, high in equipment processing speed, and powerful in functions. The high performance processor is adopted, multi-path of analog / digital (AD) and RS232 serial ports and multi-path of input / output (IO) serial ports are externally expanded, and the underwater observation network control circuit supports high-speed high-capacity peripheral storage.
Description
technical field [0001] The invention belongs to the field of wireless communication and embedded technology, and in particular relates to an underwater observation network control circuit. Background technique [0002] The ocean, which occupies more than 70% of the earth's surface area, contains a large number of biological resources and mineral resources, especially in the deep sea and the pelagic waters, there are still many precious resources sleeping outside the field of vision of human beings. The immaturity of basic technical means in the special medium environment is regarded as the key factor that prevents the large-scale development of marine resources. Among them, the monitoring technology for underwater information such as water quality information, hydrological information, and underwater acoustic information is an important general-purpose basic technology related to environmental monitoring, natural disaster prediction, marine resource investigation, underwater...
