流口水的规则应该在周末开火？

I'm using drools for alert generation and whenever I meet some condition I'm able to fire a rule and generate an alert.

我正在使用drools来生成警报,每当我遇到某种情况时,我就可以触发规则并生成警报。

My requirement further is for motion and smoke alert, we need to fire a rule on weekdays (i.e., except Saturday and Sunday).

我的要求是进一步提出运动和烟雾警报,我们需要在工作日发布规则(即星期六和星期日除外)。

How is it possible?

这怎么可能?

You can generate the alert based betwwen times and you can generate the alert by exluding the days, in this case i have done some r&d. for this you can fallow below steps:

您可以根据时间生成警报,并且可以通过排除日期来生成警报,在这种情况下,我已经做了一些研发。为此你可以在下面的步骤休息:
