基于Kinetis平台与IIC总线的环境监测浮标中控系统

Environmental monitoring buoys control system based on Kinetis platform and IIC bus

对于运行在近海岸的环境监测浮标,由于需要外接气象传感器、磷酸盐传感器、水质传感器等一系列的传感器,所以一般微控制器的接口资源并不够用。考虑到需要兼顾功耗与接口数量,系统用IIC总线来拓展接口,项目使用恩智浦公司Kinetis系列的32位微控制器K60来做主控芯片,而在子板上采用S08系列低成本8位单片机MC9S08QE128。这样,既能兼顾主控的运算能力与子板的接口拓展能力,又能在整体上实现一个较低的功耗表现。

For environmental monitoring buoys running near the coast, because of the need for a series of sensors, such as weather sensors, phosphate sensors, water quality sensors, and so on, the interface resources of the general microcontroller are not enough. Considering the need to take into account both the power consumption and the number of interfaces, the system uses IIC bus to expand the interface. The project uses the 32 bit microcontroller K60 of Kinetis series of NXP company to make the main control chip, and the S08 series low cost single chip computer MC9 S08 QE128 is used on the sub board. In this way, both the operation ability of the master control and the interface expansion ability of the sub boards can be taken into account, and a lower power consumption performance can be achieved on the whole.
