监护仪参数模块的插件式设计

为解决监护仪对不同组合参数模块的支持,同时实现参数模块的共享,本文提出了一种监护仪参数模块的插件式设计方法.其设计思路是把参数模块与监护仪主机拆分开来,通过监护仪主机上的接口板程序对各槽位进行定时轮询,由握手信息确认参数模块的加载/卸载;通过软件处理方式解决插拔过程中出现的抖动问题;利用优先级和一定的排布算法实现屏幕的动态排布.实验验证结果证实,该设计方法可获得良好的实际效果,目前已成功应用于新型的插件式监护仪上.

Pluggable Design for Monitor's Parameter Modules

In order to make the monitor support the parameter modules with different combinations and to realize the share of parameter modules, this paper proposed a kind of pluggable design method for monitor＇ s parameter modules. In this process, the parameter modules were separated from monitor mainframe. Connective board＇s time polls on each groove was used for confirming the parameter modules＇ loading or uninstalling. A software was programmed to solve the problem of wobble during the period of plug-pull. The PRI and arrangement arithmetic were used to realize screen＇s dynamic arrangement. The experimental verification showed the design with a good effect, and the proposed design had been utilized in new kinds pluggable monitors.
