基于單片機(jī)無線通信的應(yīng)急交通控制研究

研制了基于單片機(jī)無線通信技術(shù)的應(yīng)急交通控制系統(tǒng)。系統(tǒng)采用AT89C52 作為核心控制器，手持遙控端的AT89C52 單片機(jī)實(shí)現(xiàn)控制命令的判斷、編碼和經(jīng)ZT-TR43S 無線數(shù)傳模塊發(fā)送；路口控制機(jī)執(zhí)行預(yù)先設(shè)定的交通信號(hào)控制方案，當(dāng)接收無線信號(hào)后轉(zhuǎn)入相應(yīng)的
應(yīng)急控制程序。本文介紹了系統(tǒng)的總體方案、部分硬件設(shè)計(jì)和軟件設(shè)計(jì)。

Abstract ： This paper developed traffic emergency control system based on wireless
communication technique. Single-chip microcontroller AT89C52 is core of the control system. In manual controlling equipment, the command which is judged and coded through AT89C52 will be transmitted by ZT-TR43S wireless transport module. The local controller usually performs the scheme which is preplanned. When receiving wireless signal, the local controller will perform the corresponding program. The total system, handware and software design is introduced in details.
