| 摘 要： | 目前货舱进水报警系统大多采用PLC控制方式，这样不仅成本高，而且现场安装调试均不甚方便，特别是在货舱数不可能统一的前提下，实现扩展也不方便。为了解决这些问题，设计了基于PIC单片机的货舱进水报警系统，采用多点配置方式，即每个船舱设置一个报警系统，所有单个报警系统的信息均通过RS485总线传输到上位机实现集中报警。

| Abstract: | At present, the PLC control mode is adopted for the most part of cargo hold flooding alarm system, but the mode has some shortcomings of high cost, not convenient for on-site installation and debugging and also not easy for system expanding, especially under the precondition in which it is impossible that there is a unified number for the cargo holds. In order to solve these problems, the PIC MCU based cargo hold flooding alarm system is designed and the muhipoint configuration mode is used, namely an alarm system is set for each cabin. The information of every individual alarm systems is transmitted to the upper computer to realize the centralized alarm through RS 485 bus. |
