Modbus在生物采样电子监控系统中的应用

The Application of Modbus Protocol in Electronic Monitoring System for Larva Sampling

针对深海生物幼体采样的需要,提出一种基于Modbus协议的电子监控系统。首先介绍了Modbus通信协议,并重点研究了Modbus主从机的软件设计。设计实现了电子监控系统的软硬件部分。文章设计的监控系统将电子监控引入深海生物幼体采样,并实现了Modbus规约的网络化控制。系统大大提高了采样系统各部件的工作效率和稳定性,低功耗模式的设计也延长了采样系统的工作时间,一定程度上缓解了海底设备电力不足的困境。系统也适用于普通渔场生物拖网的控制。

In order to meet the need of deep-sea larva sampling, an electronic monitoring system based on the Modbus protocol is suggested. It describes the Modbus protocol and then focus on the software design of the master and slave of the Modbus communication system. The software and the hardware designs of the electronic system are realized. The monitoring system inducts the electronic monitoring into larva sampling and fulfills the Modbus network control. It enhances the efficiency and stability of every part of the sampling system. Low-power mode extends working time of the sampling system and solves the power supply shortage situation to some extent. The monitoring system can also apply to the plankton trawl control in fishery.
