可视化网关编程系列教程-----（5）定时任务

前言

最近工作太忙，没时间更新教程。今日得以空闲，没事来写两篇教程给大家学习一下。
今天这篇教程是关于定时任务的，非常简单而且易用。

1. 安装模块

打开节点管理，在安装里输入，node-red-contrib-scheduler，然后点击安装。

2. 了解模块的作用

安装好以后，会发现这个节点有3个输出，分别是msg，value，text。一般我们只需要value就行。

详细点开以后，会看到这些配置参数，一般我们设置好经纬度和定时时间即可。
详细参数

3. 开始使用

案例1，上海，黄昏的时候打开花园灯，早上7点关闭，每天都执行

案例2，柏林某企业，白天走道区域感应控制，夜晚加班时间禁用感应，并且打开走道灯

这个节点相当好用而且稳定，大家可以自己试试，唯一的缺点就是不可以过滤节假日，由于全球的节假日太多了，所以这也是情理之中。
