【Abstract】 The working principle of multi - depth deepsea microplankton sampler is introduced. The control system is composed of portable input device and main controller. Singlechip is chosen as microcontroller for the input device and the value of sampling depth is set with keyboard. Main controller uses Singlechip as microcontroller and is used to realize self - dependent sampling. The hardware structure and software design procedure are introduced in detail. Two design schemes for improving the sampler working reliability are proposed. Experiment results show that the control system has the advantage of reasonable structure, reliability performance and can realize designed requirement.更多还原
