根据有方GPRS的智能电梯控制系统

构思布景

现在的许多企业都在很高的楼层作业，每天上下班顶峰期，电梯门口总是会排上很长的队，为了让电梯用最快的速度将一切的肿痛送到指定楼层，需求给出一些改善；下班的时分，咱们楼层很高，肿痛往往需求花费一些时刻等候电梯抵达自己的楼层，运用一些改善能够让肿痛把握电梯状况，然后节约一些等电梯的时刻。

功用特征

• 功用一：咱们对电梯作出这样的改善：在上班顶峰时段，电梯只能向上运转时开门搭载上朝楼上去的人员，即电梯只会呼应朝上行的按键,在向下运转的过程中，不会呼应任何按钮。鄙人班时刻段，也能够做相应修正。然后节约大多数人的时刻，将人快速送达指定地址。

• 功用二： 平常，咱们作业人员多作业于很高的楼层，而此刻的电梯或许处于一楼，所以能够先向操控中心发送一条短信来获取电梯的实践方位，假如电梯此刻间隔自己地址的楼层还有一段间隔，就能够提早向操控中心发送一条恳求短信，这时操控中心会向电梯运用端发送恳求信号，指令电梯开往指定的楼层，然后削减等候的时刻。

具体操作

只需求修正短信XY#到指定的电话号码就能够长途操控电梯的运转。其间X代表发信人地址楼层，Y代表发信人酿制抵达的楼层。电梯也会对发信人的要求进行应对，告知电梯当时的运转状况，好让发信人把握好乘坐电梯的时刻。

GPRS的运用

咱们首要用到了有方GPRS模块的短信收发功用。首要用于在上下班顶峰时协助肿痛取得电梯状况信息、向电梯发送停靠指令。指令电梯开往指定的楼层，然后削减等候的时刻。电梯运用端运用有方GPRSM660+模块来接纳来自操控中心的信号并发送短信作为应对，然后完成用户与电梯的交互通讯。
