基于有方GPRS的智能電梯控制系統(tǒng)

構(gòu)思背景

目前的很多企業(yè)都在很高的樓層辦公，每天上下班高峰期，電梯門口總是會(huì)排上很長(zhǎng)的隊(duì)，為了讓電梯用最快的速度將所有的員工送到指定樓層，需要給出一些改進(jìn)；下班的時(shí)候，由于樓層很高，員工往往需要花費(fèi)一些時(shí)間等待電梯到達(dá)自己的樓層，利用一些改進(jìn)可以讓員工掌握電梯狀態(tài)，從而節(jié)省一些等電梯的時(shí)間。

功能特色

• 功能一：我們對(duì)電梯作出這樣的改進(jìn)：在上班高峰時(shí)段，電梯只能向上運(yùn)行時(shí)開(kāi)門搭載上朝樓上去的人員，即電梯只會(huì)響應(yīng)朝上行的按鍵,在向下運(yùn)行的過(guò)程中，不會(huì)響應(yīng)任何按鈕。在下班時(shí)間段，也可以做相應(yīng)修改。從而節(jié)省大多數(shù)人的時(shí)間，將人快速送達(dá)指定地點(diǎn)。

• 功能二： 平時(shí)，由于工作人員多工作于很高的樓層，而此時(shí)的電梯可能處于一樓，所以可以先向控制中心發(fā)送一條短信來(lái)獲取電梯的實(shí)際位置，如果電梯此時(shí)距離自己所在的樓層還有一段距離，就可以提前向控制中心發(fā)送一條請(qǐng)求短信，這時(shí)控制中心會(huì)向電梯應(yīng)用端發(fā)送請(qǐng)求信號(hào)，命令電梯開(kāi)往指定的樓層，從而減少等待的時(shí)間。

具體操作

只需要編輯短信XY#到指定的電話號(hào)碼就可以遠(yuǎn)程控制電梯的運(yùn)行。其中X代表發(fā)信人所在樓層，Y代表發(fā)信人將要到達(dá)的樓層。電梯也會(huì)對(duì)發(fā)信人的要求進(jìn)行應(yīng)答，告訴電梯當(dāng)前的運(yùn)行情況，好讓發(fā)信人掌握好乘坐電梯的時(shí)間。

GPRS的使用

我們主要用到了有方GPRS模塊的短信收發(fā)功能。主要用于在上下班高峰時(shí)幫助員工獲得電梯狀態(tài)信息、向電梯發(fā)送?？恐噶?。命令電梯開(kāi)往指定的樓層，從而減少等待的時(shí)間。電梯應(yīng)用端使用有方GPRSM660+模塊來(lái)接收來(lái)自控制中心的信號(hào)并發(fā)送短信作為應(yīng)答，從而實(shí)現(xiàn)用戶與電梯的交互通信。
