作品的基本功能有剩余车位识别及显示、分区检修、快捷收费系统、智能导航、剩余车位识别及显示几个模块,将解决现有停车场找车位难,找车耗时长,收费繁琐(人工收费)等情况,能够帮助司机朋友快速地找到停车位,以此节约大量时间。
本文将介绍智能车位向导系统的工作原理、作品结构、作品特色以及市场前景等相关信息,旨在明确阐述本作品的设计意图及创作方向。
二.作品介绍前言:今时代,汽车作为新一代的代步工具早已在近20年内融入了千家万户。
中国作为世界上人口第一大国,车辆的基数也可谓是庞大,但与此同时,由于种种国情以及城市化程度的限制,国内实现智能化管理的大型停车场数量远远不及国外,导致各大城市汽车停车困难的问题十分严峻,还进一步导致了乱停乱放现象屡见不鲜,使有车一族的出行变得很麻烦。
针对这一问题,国内外技术人士开发出的现代化停车场系统,在一定程度上缓解停车难的问题。
我们针对现有的停车场系统进行了进一步的改进,增加了一些实际可行的功能,在原有的自动收费,停车记录查询之外,让司机朋友们能直观的了解该停车场车位的空余情况。
现行停车场:基本没有智能导航及空余车位显示功能,司机寻找车位耗时,收费标准复杂,不便于停车场的整体管理。
需要管理人员驻守,实时观测进出车辆并进行手动收费,耗费人力物力。
设计停车场:动态实时显示停车场剩余车位数量,并设计智能导航,指引司机快速找到车位,节约大量时间。
同时通过单片机的控制系统,显示停车场分区车位剩余数量,并对进出车辆检验,对车辆驶入及驶离时间统计,并由此由单片机系统自动计费,在车辆驶离时,由出口处由机器自动感应IC 卡收费,整个过程方便、快捷,也便于管理人员查看。

HT46ru232单片机简介 (2011-01-24 17:17:56)
标签: 杂谈 分类: 单片机学习笔记
一、总体介绍: HT46RU232 是 8 位高性能精简指令集单片机,专门为需要 A/D 转换产品而设计,例如传感器信号输入。 低功耗、I/O 使用灵活、可编程分频器、计数器、振荡类型选择、多通道 A/D 转换、脉宽调制功能、IIC 接口、UART 总线,暂停和唤醒功能,使这款单片机可以广泛应用于传感器的 A/D 转换、马达控制、工业控制、消费类产品,子系统控制器等。 HT46ru232单片机有两种封装形式,一为下图所示,28脚的DIP封装,另外一种为48脚的SOP封装。
二、系统时钟: HT系列单片机的指令周期为Fsys/4,其系统时钟可以选用石英晶振4MHz或者8MHz。也可以选择RC振荡电路来实现。两种形式如下图: 如果选用外部 RC 振荡方式,在 OSC1 与 VSS 之间需要接一个外部电阻,其阻值为 30kΩ~750kΩ;而 OSC2 上会输出带上拉的系统频率的 4 分频信号,可用于同步外部逻辑。RC 振荡方式是一种低成本的方案,但是,RC振荡频率会随着VDD、温度和芯片自身参数的漂移而产生误差。因此,在需要精确振荡 频率作为计时操作的场合,并不适合使用 RC 振荡方式。 如果选用晶体振荡方式,在 OSC1和OSC2之间需要连接一个晶体,用来提供晶体振荡器所需的反馈和相移,除此之外,不再需要其它外部元件。另外,在OSC1和 OSC2之间也可使用谐振器来取代晶体振荡器,但是在OSC1和OSC2 需要多连接两个电容(如果振荡频率小于1MHz)。 WDT 振荡器是一个内部RC 振荡器,并不需要连接任何外部元件。当系统进入暂停模式时,系统时钟会停止,但 WDT 振荡器会继续工作,其振荡周期大约为 65µs/5V。如果要降低功耗,可在掩膜选项中关闭WDT 振荡器。
三、复位电路: HT系列单片机提供了三种方法来产生系统复位。 ·正常运行时由RES引脚发生复位 ·暂停模式下由RES引脚发生复位 ·正常情况下由看门狗溢出发生复位 暂停模式中的看门狗定时器溢出与其它系统复位状况不同,因为看门狗定时器溢出会执行“热复位”,只有程序计数器PC 和堆栈指针SP 被复位,而系统其它部分都保持原有状态。在其它复位状态下,某些寄存器不会改变。在初始复位时,大部分寄存器会复位成初始的状态。通过检测PDF和TO 标志,即可判断出各种不同的复位原因。
为了保证系统振荡器起振并稳定运行,系统复位或由暂停状态唤醒时,系统启动定时器(SST)提供了一个额外的延迟时间,共 1024个系统时钟周期。 系统由暂停模式唤醒或上电复位时,SST 会被加在复位延时中。上电复位时会加入额外的SST 延迟,而由暂停模式唤醒仅有 SST 延迟。系统复位时各功能单元的状态如下所示:
四、定时器/计数器 HT46RU232 有两个定时/计数器(TMR0,TMR1)。定时/计数器 0 是一个 16 位向上计数器,其时钟来源可以是外部信号输入或内部时钟,内部时钟为 fSYS。定时/计数器 1 是一个 16 位向上计数器,其时钟来源可以是外部信号输入或内部时钟,内部时钟为 fSYS/4。外部信号输入可以用来计数外部事件、测量时间间隔、测量脉冲宽度或产生一个精确的时基信号。有六个与定时/计数器0/1有关的寄存器, TMR0H(0CH)、 TMR0L(0DH)、 TMR0C(0EH)、 TMR1H(0FH)、 TMR1L(10H)、TMR1C(11H)。写入 TMR0L(TMR1L)只能将数据写到低字节缓冲器(8 位),而写入TMR0H(TMR1H)会把指定数据和低字节缓冲器的数据分别写到 TMR0H(TMR1H)和 TMR0L(TMR1L)预置寄存器中,定时/计数器 0/1 预置寄存器的内容只有在写入 TMR0H(TMR1H)时才会被改变。读取TMR0H(TMR1H)会把TMR0H(TMR1)的内容送至目标单元,而TMR0L(TMR1L)的值被送至低字节缓冲器中。读 TMR0L(TMR1L)将读取低字节缓冲器的值。TMR0C(TMR1C)是定时/计数器 0/1 控制寄存器,用来定义定时/计数器一些选项。
TMR0C寄存器的位定义: 位7、6为定义定时器工作模式:T0M1,T0M0 00--------未用 01--------事件计数模式(对外部时钟计数) 10--------定时器模式(内部模式) 11--------脉冲宽度测量模式 位5----未用,一般使用定义为0 位4----T0ON,打开关闭定时器(0关闭,1打开) 位3----T0E,定时器/计数器触发模式 位2、1、0定义定时器时钟预分频级数,以T0PSC2-0,8进制数为指数n,Fint=Fsys/(2的n次方).
TMR1C寄存器的位定义: 类似TMR0C,但TMR1C没有对低三位定义。 TMR2C寄存器的位定义: 同TMR0C寄存器。 五、UART---异步串行口 HT46RU232 具有一个全双工的异步串行通信口,可以很方便的与其它具有串行口的芯片通讯。UART具有许多功能特性,发送或接收一个8 位或9位数据帧的串行数据,当数据超速或数据帧不正确时, UART可以检测出错误。UART功能占用一个内部中断向量,当接收到数据或数据发送结束,触发 UART中断。
串行口主要由3个UART寄存器来控制和检测(UART、UART1、UART2) UART(只读) bit0-7的定义为: · TXIF TXIF 是发送数据寄存器为空标志。若 TXIF=0,数据还没有从缓冲器加载到移位寄存器中;若TXIF=1,数据已从TXR寄存器中加载到移位寄存器。读取 USR寄存器再写TXR寄存器将清除TXIF。当TXEN被置位,即使发送缓冲器未满,TXIF也会被置位。 · TIDLE TIDLE是数据发送完成标志位。若 TIDLE=0,表明数据传输中。当TXIF=1且数据发送完毕或暂停字被发送时,TIDLE置位。TIDLE=1,TX引脚空闲。读取 USR寄存器再写TXR寄存器将清除TIDLE位。当数据字节或暂停字符排列好并准备发送时,TIDLE不发生变化。 · RXIF RXIF 是接收寄存器状态标志。当 RXIF=0,表明 RXR 寄存器为空;当 RXIF=1,表明 RXR 寄存器接收到新数据。当数据从移位寄存器加载到RXR寄存器,如果UCR2寄存器中的RIE=1,则会触发中断。当接收数据时检测到一个或多个错误时,相应的标志位 NF、FERR或PERR会在同一周期内置位。读取USR寄存器再读RXR寄存器,如果RXR寄存器中没有新的数据,那么将清除RXIF标志。 · RIDLE RIDLE是接收状态标志。若 RIDLE=0,表明正在接收数据;若RIDLE=1,表明接收器空闲。在接收到停止位和下一个数据的起始位之间,RIDLE被置位,表明 UART空闲。 · OERR OERR 是过速错误标志,表示接收缓冲器溢出。若 OERR=0,表明没有数据溢出;若 OERR=1,表明发生了过速错误,它将禁止下一组数据的接收。先读取 USR寄存器再读RXR寄存器将清除此标志位。
·FERR FERR 是帧错误标志位。若 FERR=0,表明没有帧错误发生;若 FERR=1,表明当前的数据发生了帧错误。先读取USR寄存器再读 RXR寄存器将清除此位。 · NF NF是噪声干扰标志。若 NF=0,表明没有受到噪声干扰;若 NF=1,表明 UART接收数据时受到噪声干扰。它与 RXIF 在同一个周期内置位,但不会与过速标志位同时置位。先读取 USR 寄存器再读 RXR寄存器将清除此标志位。 · PERR PERR 是奇偶校验出错标志。若 PERR=0,表明奇偶校验正确;若 PERR=1,表明接收到的数据奇偶校验出错。只有使能了奇偶校验此位才有效。先读取 USR寄存器再读RXR寄存器将清除此位。
UCR1寄存器bit0-7定义为:
· TX8 此位只有在传输数据为 9 位的格式中有效,TX8 用来存储发送数据的第 9 位。BNO 是用来控制传输位数是 8位还是 9位。 · RX8 此位只有在传输数据为 9 位的格式中有效,RX8 用来存储接收数据的第 9 位。BNO 是用来控制传输位数是 8位还是 9位。 · TXBRK TXBRK是暂停字发送控制位。若 TXBRK=0,表明没有暂停字要发送,TX引脚正常操作;若 TXBRK=1,表明将会发送暂停字,发送器将发送逻辑 0。若 TXBRK 为高,缓冲器中数据发送完毕后,发送器将至少保持13位宽的低电平直至TXBRK复位。 · STOPS 此位用来设置停止位的长度。若 STOPS=1,表明有两位停止位;若STOPS=0,表明只有一位停止位。 · PRT 奇偶校验选择位。若PRT=1,表明选择奇校验;若PRT=0,表明选择偶校验。
· PREN 此位为奇偶校验使能位。若PREN=1,表明使能奇偶校验;若 PREN=0,表明除能奇偶校验。 · BNO 选择数据长度为 8位或 9位格式。若BNO=1,表明传输数据为 9位;若BNO=0,表明传输数据为8位。若选择了9位数据传输格式,RX8和TX8将分别存储接收和发送数据的第 9位。 · UARTEN 此位为 UART 的使能位。若 UARTEN=0,表明 UART 除能,RX 和 TX 可用作普通输入/输出口;若UARTEN=1,表明UART使能,TX和RX将分别由TXEN和 RXEN控制。当 UART除能,系统将清除缓冲器,所有缓冲器中的数据将被忽略,另外波特率计数器、错误和状态标志位被复位,TXEN、RXEN、TXBRK、 RXIF、OERR、FERR,PERR和NF清零;而 TIDLE、TXIF和RIDLE置位,UCR1、UCR2和BRG寄存器中的其它位保持不变。若 UART工作时UARTEN清零,所有发送和接收将停止,模块也将复位成上述状态。当UART再次使能时,它将在上次配置下重新工作。
