本申请要求 2012 年 10 月 29 日提交至中国知识产权局的， 申请号为 201210421075.8, 名称为 "自动检票方法及自动检票装置" 的中国发明专利申请的优 先权， 其全部公开内容结合于此作为参考。 技术领域 本发明涉及检票领域， 具体而言， 涉及一种自动检票方法及自动检票装置。 背景技术 为了提高检票效率、 降低人工劳动强度， 自动检票装置已经越来越多的应用于铁 路、 公路、 地铁的检票大厅用于取代人工检票。 自动检票装置通常包括检票机构、 通 道以及闸门， 其中， 乘客在检票机构处提供票纸后经通道运动至闸门， 当检票机构检 测票纸有效后控制闸门开启， 以便乘客通过。 自动检票装置中， 一般都在其通道中按 一定规则安装有多个光电传感器， 自动检票装置的控制器通过光电传感器的输出信号 检测通道中通行的乘客的状态， 判断通道内是否存在非法尾随的乘客， 进而确定是否 开启闸门允许乘客通行。 申请号为 201110099452.6的中国专利公开了一种自动检票机。 如图 1所示， 该自 动检票机包括： 检测系统 1 以及与其连接的第一传感器组 2和第二传感器组 3， 第一 传感器组 2和第二传感器组 3根据光电传感器的输出信号获取当前乘客的通行状态。 其中， 第一传感器组 2用于采集乘客的第一通行状态信号， 当第一传感器组 2中相邻 被遮挡的传感器之间存在有未被遮挡的传感器时， 判定为多体通行状态， 即乘客以拖 拽等形式携带行李、 乘客携带儿童或有其他乘客尾随的通行状态， 否则， 为单体通行 状态， 即不携带任何行李或是以抱、 背等形式携带行李的一个乘客的通行状态。 第二 传感器组 3用于采集乘客的第二信号， 第二传感器组 3中的传感器进行"数腿"检测， 当一个或几个传感器被连续遮挡时判为存在一条"腿"， 当相邻被遮挡的传感器之间存 在有未被遮挡的传感器时判为存在不同的"腿"。 当第一传感器 2检测到乘客通行状态 为多体通行状态中其他乘客尾随的情况时， 则当第二传感器组 3检测到 "两条腿"时不 报警， 检测系统 1控制闸门打开； 当第二传感器组 3检测到 "三条腿"时判定存在尾随 过检的情况， 检测系统 1控制报警系统进行报警。 上述专利公开的自动检票机在一定情况下能正确检测是否存在乘客尾随过检的情 况， 但是， 该自动检票机通过检测在某一时刻传感器的状态来判断通道中乘客的通行 状态， 由于通道中通行的乘客或其携带物为运动状态， 且其运动状态存在不确定性， 比如， 某一位处于单体通行状态的乘客在行走过程中其胳膊可能会发生摆动， 当该乘 客通过第一传感器组 2时， 如果在判断时刻， 该乘客的胳膊处于摆动状态， 其身体和 胳膊分别遮挡住一个传感器， 且两个被遮挡的传感器之间存在有未被遮挡的传感器， 则该处于单体通行状态的乘客就会被误判断为多体通行状态； 再比如， 某一位处于单 体通行状态的乘客携带雨伞、 手提包等小件物品， 当该乘客通过第二传感器组 3时， 如果在判断时刻， 该乘客的胳膊处于摆动状态， 其携带物遮挡住一个传感器、 其两条 腿分别遮挡住一个传感器， 且相邻两个被遮挡的传感器之间存在有未被遮挡的传感器 时， 则该乘客的携带物和两条腿被判断为"三条腿"； 在第一传感器组 2误判断乘客为 多体通行状态中其他乘客尾随情况， 第二传感器组 3误检测到"三条腿 "时， 自动检票 机误判断存在尾随过检情况， 检测系统 1控制报警系统进行报警。 由此可见， 相关专 利公开的自动检票机的检测方法存在检测不准确的问题。 针对相关技术中自动检票机对乘客通行状态的检测不准确的问题， 目前尚未提出 有效的解决方案。 发明内容 本发明的主要目的在于提供一种自动检票方法及自动检票装置， 以解决相关技术 中自动检票机对乘客通行状态的检测不准确的问题。 为了实现上述目的， 根据本发明的一个方面， 提供了一种自动检票方法。 该自动 检票方法包括： 分别记录第一传感器、 第二传感器和第三传感器连续处于相同状态的 次数， 其中， 在乘客的通行方向上， 第一传感器、 第二传感器和第三传感器依次设置 在检票通道中； 当检测到乘客到达第三传感器的位置时， 统计在设定时间段内记录的 第一传感器、 第二传感器和第三传感器连续处于相同状态的次数； 以及根据统计的结 果计算在设定时间段内检票通道内需购票乘客的人数。 进一步地， 根据统计的结果计算在设定时间段内检票通道内需购票乘客的人数包 括： 首先根据统计的结果分别计算第一传感器、 第二传感器和第三传感器检测到的需 购票乘客的人数， 然后按照以下任意一种或者多种方法确定在设定时间段内检票通道 内需购票乘客的人数： 当第一传感器、 第二传感器和第三传感器中任一传感器检测到 的需购票乘客的人数为 0时， 判定检票通道内需购票乘客的人数为 0; 当第一传感器、 第二传感器和第三传感器检测到的需购票乘客的人数一致时， 判定检票通道内需购票 乘客的人数为一致的人数； 当第一传感器、 第二传感器和第三传感器检测到的需购票 乘客的人数存在两种情况时， 将其中的两个检测结果一致的人数作为检票通道内需购 票乘客的人数； 以及当第一传感器、 第二传感器和第三传感器检测到的需购票乘客的 人数各不相同时， 将三个传感器的检测结果的中间值作为检票通道内需购票乘客的人 数。 进一步地， 在本发明的自动检票方法中， 分别记录第一传感器、 第二传感器和第 三传感器连续处于相同状态的次数包括： 每间隔预设时间分别记录一次第一传感器、 第二传感器和第三传感器的状态； 当任一传感器连续两次记录的状态相同时， 将该传 感器的连续状态次数进行加 1操作， 当任一传感器连续两次记录的状态不同时， 将该 传感器的连续状态次数置 1 ; 以及当任一传感器连续两次记录的状态不同时， 将该传 感器连续处于当前状态的上一状态的次数存储至与该传感器对应的第一数据集合中， 其中， 根据统计的结果计算检票通道内需购票乘客的人数包括按照以下方法统计每个 传感器检测到的检票通道内需购票乘客的人数： 对第一数据集合中的数据进行去噪处 理， 得到第二数据集合， 其中， 去噪处理包括： 当第一数据集合 Cln中所存储的非零 数据的个数大于三个时， 搜索第一数据集合 Cln中第一个非零数据和最后一个非零数 据之间的最小数据 dnm并对其进行判断， 当 dnm小于预设阈值 N时， dnm及 dnm+1被累 加到 dtim^上， dnm+2在第一数据集合 Cln中的位置向前移动， 其序号变为 m， dnm+2 后面的数据在第一数据集合 Cln中的位置也依次向前移动，第一数据集合 Cln中空出 的最后两个序号的位置用零进行填充， 当第一数据集合 Cln内的最小数据不小于预设 阈值 N或第一数据集合 Cln内只剩余三个非零数据时， 停止进行数据搜索及判断， n 为传感器序号， 取值为 1、 2、 3， m为 Cln内数据的序号； 以及将第二数据集合中存 储的表示每个传感器处于被遮挡状态的非零数据的个数作为该传感器检测到的检票通 道内需购票乘客的人数。 进一步地， 当第三传感器检测到以下结果时， 确定检测到乘客到达第三传感器的 位置： 每间隔预设时间记录一次第三传感器的状态； 以及当第三传感器连续处于被遮 挡状态的次数达到预设阈值 M时， 确定检测到乘客到达第三传感器的位置。 进一步地， 该自动检票方法还包括： 在接收到多张票纸时， 检测多张票纸中有效 票纸的数量， 在根据统计的结果计算检票通道内需购票乘客的人数之后， 该自动检票 方法还包括： 判断检票通道内需购票乘客的人数是否大于有效票纸的数量， 当判断出 检票通道内需购票乘客的人数不大于有效票纸的数量时， 控制闸门打开以允许乘客在 检票通道中通行。 进一步地， 该自动检票方法还包括： 检测是否有乘客退出检票通道； 每检测到有 一个乘客退出检票通道， 将有效票纸的数量进行减 1操作以对所检测到的多张票纸中 有效票纸的数量进行更新， 同时将计算得到的检票通道内需购票乘客的人数进行减 1 操作以对计算到的检票通道内需购票乘客的人数进行更新； 判断多张票纸中有效票纸 的数量是否有增加， 或者， 判断计算到的检票通道内需购票乘客的人数是否有增加； 以及当判断出多张票纸中有效票纸的数量有增加或者计算到的检票通道内需购票乘客 的人数有增加时， 再次判断检票通道内需购票乘客的人数是否大于有效票纸的数量。 为了实现上述目的， 根据本发明的另一方面， 提供了一种自动检票装置。 该自动 检票装置包括： 记录单元， 用于分别记录第一传感器、 第二传感器和第三传感器连续 处于相同状态的次数， 其中， 在乘客的通行方向上， 第一传感器、 第二传感器和第三 传感器依次设置在检票通道中； 统计单元， 用于当检测到乘客到达第三传感器的位置 时， 统计在设定时间段内记录的第一传感器、 第二传感器和第三传感器连续处于相同 状态的次数； 以及计算单元， 用于根据统计的结果计算设定时间段内检票通道内需购 票乘客的人数。 进一步地， 计算单元用于首先根据统计的结果分别计算第一传感器、 第二传感器 和第三传感器检测到的需购票乘客的人数， 然后按照以下任意一种或者多种方法确定 在设定时间段内检票通道内需购票乘客的人数， 其中， 计算单元包括以下任意一个或 多个计算单元： 第一计算单元， 用于当第一传感器、 第二传感器和第三传感器中任一 传感器检测到的需购票乘客的人数为 0时， 判定检票通道内需购票乘客的人数为 0;

Flash存储器 13用于存储自动检票装置的控制程序， 同时， Flash存储器 13中还 用于存储第一预设阈值 M和第二预设阈值 N， 其中， 第一预设阈值 M判断是否开始 统计一个设定时间段内相关传感器的状态， 第二预设阈值 N用于对相关传感器状态统 计所得到的第一数据集合进行去噪处理。 RAM存储器 14用于为自动检票装置的控制程序运行提供存储空间， 同时， RAM 存储器 14还用于存储控制程序运行过程中所需要的变量， 比如， RAM存储器 14用于 存储检票单元 15读取的票纸的信息， RAM存储器 14还用于存储第一数据集合 Cln、 第二数据集合 C2n以及传感器连续状态次数 SCnt_n，其中 n为传感器序号，取值为 1、 2、 3， 第一数据集合 Cln、 第二数据集合 C2n中均包括在满足设定要求的设定时间段 内相关传感器状态统计的数据，传感器连续状态次数 SCnt_n用于记录第 n个传感器连 续处于同一状态的次数。 检票单元 15用于读取乘客所提供的票纸的信息， 检票单元 15可以为读取非接触 型 IC卡的读卡模块，如射频模块，也可以为读取接触型磁卡的读卡模块，如读磁模块， 还可以为既可以读取非接触型 IC卡又可以读取接触型磁卡的混合型读卡模块。 传感器单元 16 用于检测自动检票装置的通道中通行的乘客及其携带物的通行状 态， 其中， 传感器单元 16包括有按一定规则排布的多个传感器， 该多个传感器可以是 透射传感器， 也可以是反射传感器， 每个传感器都包括有光发生器和光接收器， 当传 感器为反射传感器时， 每个传感器的光发生器和光接收器位于自动检票装置 100的通 道同一侧， 当通道中有乘客或其携带物经过，乘客或其携带物位于传感器所在位置时， 传感器处于被遮挡状态， 光接收器接收由通行的乘客或其携带物反射的光发生器发生 的光， 此时， 光接收器输出第一检测信号， 如高电压， 当乘客或其携带物没有位于传 感器所在位置时， 传感器处于不被遮挡状态， 光接收器不能接收光发生器发生的光， 此时， 光接收器输出第二检测信号， 如低电压； 当传感器为透射传感器时， 每个传感 器的光发生器和光接收器分别位于通道的两侧， 二者相对设置， 当乘客或其携带物没 有位于传感器所在位置时， 传感器处于不被遮挡状态， 光接收器接收光发生器发生的 光， 此时， 光接收器输出第一检测信号， 如高电压； 当通道中有乘客或其携带物经过， 乘客或其携带物位于传感器所在位置时， 传感器处于被遮挡状态， 光接收器不能接收 光发生器发生的光， 此时， 光接收器输出第二检测信号， 如低电压。 由此可见， 对于 传感器单元 16中的每个传感器，当传感器被通道中经过的乘客或其携带物遮挡和不被 通道中经过的乘客或其携带物遮挡时， 其光接收器接收的光强度不同， 因此， 输出的 检测信号也不同，控制单元 11通过检测传感器的光接收器的输出信号即可判断当前时 刻该传感器是否处于被遮挡状态， 即判断通道中是否有通行乘客或其携带物经过该传 感器。 闸门单元 17用于允许或禁止通道中的乘客通行， 闸门单元 17包括闸门电机驱动 器 171、 闸门电机 172、 以及闸门 173， 其中， 闸门电机驱动器 171接收控制单元 11 输出的驱动脉冲并输出闸门电机 172的输出轴转动所需要的电流， 闸门电机 172的输 出轴与闸门 173传动连接，闸门电机 172的输出轴转动时驱动闸门 173转动预设角度， 从而使闸门 173达到打开或关闭状态。 自动检票装置还包括指示单元 18， 指示单元 18用于根据自动检票装置 100的通 道中乘客的购票信息及通行状态输出各种信息， 指示单元 18包括通行指示模块 181、 检票指示模块 182以及报警模块 183， 其中， 通行指示模块 181可为一指示灯、 液晶 显示屏等， 用于指示是否允许乘客进入自动检票装置 100的通道， 检票指示模块 182 可为一液晶显示屏、 语音装置等， 用于指示通行乘客所提供的票纸是否为有效票纸， 报警模块 183可为一蜂鸣器、 喇叭、 语音装置等， 用于在票纸无效或有其他乘客尾随 过检时发出报警信息。 图 3a至图 3c示意出了根据本发明第一实施例的自动检票装置的结构组成， 图 3a 是根据本发明第一实施例的自动检票装置的立体图， 如图 3a所示， 自动检票装置 100 包括两个相对设置的本体 21， 二者之间形成用于供乘客通行的通道 22， 本体 21的面 向通道 22的一侧上安装有闸门 173， 闸门 173可以处于打开或者闭合状态， 例如， 闸 门 173的门翼可以以本体 21的上的直线 0为轴心， 在与通道 22的通行方向呈 0~180 度角度的范围内转动，当闸门 173的门翼的延伸方向与通道 22的乘客通行方向垂直时， 闸门为关闭状态，此时乘客不能在通道 22中正常通行； 当闸门 173的门翼的延伸方向 与通道 22的乘客通行方向平行时， 闸门为打开状态， 此时乘客可以在通道 22中正常 通行。 图 3b是根据本发明第一实施例的自动检票装置的侧视图， 如图所示， 通道 22沿 乘客的通行方向依次被划分为进入区 23、 安全区 24以及退出区 25三部分， 其中， 安 全区 24为闸门 173在打开及闭合的过程中其门翼在通道 22中所经过的区域， 进入区 23是指通道 22中处于通道进入口和安全区 24的之间的区域， 退出区 25是指通道 22 中处于安全区 24和退出口之间的区域。 本体 21面向通道 22的侧面上沿乘客的通行方向 （箭头 A所示方向）依次安装有 10个传感器 A1~A10，图 3b所示的自动检票装置 100的侧视图上示意了传感器 A1~A10 的排布情况，在垂直于乘客的通行方向上，传感器 A1~A3分别设置在距离地面高度为 第一高度 Η1、第二高度 H2以及第三高度 H3的位置上， 传感器 A4~A9设置在距离地 面高度为第四高度 H4的位置上， 传感器 A10设置在距离地面高度为第五高度 H5的 位置上， 其中， 第一高度 Hl <第三高度 113<第二高度 H2， 第四高度 1«<第一高度 HI , 第五高度 115<第二高度 H2， HI 取值范围为 450mm~550mm， H2取值范围为 1000mm~1200mm, H3取值范围为 650mm~750mm， H4取值范围为 150mm~250mm， H5取值范围为 850~950mm。 在乘客的通行方向上， 传感器 A1与传感器 A2之间以及 传感器 A2与传感器 A3之间的间距为 115mm~125mm， 传感器 A3与传感器 A4之间 的间距为 265mm~275mm， 传感器 A4~A9中相邻两个传感器之间以及传感器 A9与传 感器 A10之间的间距为 145mm~155mm。 当乘客在通道 22中沿箭头 A所示方向通行时， 各传感器的用途如下： 传感器 A1~A3位于通道 22的进入区 23中， 用于检测特定的设定时间段内通道
22的进入区 23中通行的需购票乘客的人数。 其中， 传感器 A2还用于进行进入区 23 中通行的乘客或其携带物的高度的检测， 当通道中通行的乘客或其携带物的高度低于 传感器 A2所在位置的高度， 即第二高度 H2时， 在乘客或其携带物位于传感器 A2所 在位置时， 传感器 A2不能被遮挡， 通过设置传感器 A2， 可以实现高度低于第二高度 H2的乘客或其携带物无需购票。 传感器 A4~A9位于通道 22的安全区 24中，用于检测通道 22的安全区 24中通行 的乘客或其携带物的状态， 控制单元 11根据传感器 A4~A9是否处于被遮挡状态控制 闸门 173的转动， 防止闸门 173的门翼将安全区 24中通行的乘客打伤， 设闸门 173 的门翼在安全区 24中向进入区 23方向完全打开时的位置为 0度位置， 向退出区 25 方向完全打开时的位置为 180度位置， 闸门 173闭合时的位置为 90度位置，在自动检 票装置 100的通道 22的通行方向为箭头 A所示方向时， 当传感器 A4~A6处于被遮挡 状态时控制单元 11只能控制闸门 173的门翼在 90度位置至 180度位置的范围内转动， 当传感器 A7~A9处于被遮挡状态时控制单元 11只能控制闸门 173的门翼在 0度位置 至 90度位置的范围内转动。 传感器 A10位于通道 22的退出区 25中， 用于检测乘客是否已离开通道 22的安 全区 24进入通道 22的退出区 25。当传感器 A10被遮挡、而安全区 24内的传感器 A4~A9 均不被遮挡时， 表示通道 22中的乘客已经离开安全区 24进入退出区 25， 此时， 控制 单元 11可以控制闸门 173关闭。 本实施例中， 传感器 A1~A10为透射传感器， 通道 22—侧的本体 21上安装有这 10个传感器的光发生器， 通道 22另一侧的本体 21上安装有这 10个传感器的光接收 器， 同一传感器的光发生器与光接收器相对设置， 自动检票装置通过检测每个传感器 的光接收器的输出信号即可判断当前时刻传感器是否处于被遮挡状态，即通道 22中是 否有经过的通行乘客或其携带物位于该传感器所在位置。 需要说明的是， 在本发明的 其他实施例中， 传感器单元 16所包括的传感器可以是设置在通道 22—侧的本体 21 上的反射传感器。 图 3c是根据本发明第一实施例的自动检票装置的主视图， 如图 3c所示， 本体 21 的正面安装有通行指示模块 181， 通行指示模块 181用于指示允许或禁止乘客进入通 道 22的信息； 本体 21与进入区 23相对应部分的顶部斜面上， 安装有检票单元 15和 检票指示模块 182，检票单元 15用于读取乘客所提供的票纸的信息，检票指示模块 182 用于显示乘客所提供的票纸是否为有效票纸； 本体 21与安全区 24相对应部分的顶部 平面上， 安装有报警模块 183， 报警模块 183用于在票纸无效或存在乘客尾随过检时 发出报警信息。 图 4a是根据本发明第二实施例的自动检票装置的侧视图， 如图 4a所示， 本实施 例与第一实施例的区别在于， 在本体 21 的侧面上增加了传感器 A11~A14， 其中， 传 感器 A12与传感器 A3、 传感器 A13与传感器 A2、 传感器 A14与传感器 A1、 以及传 感器 All与传感器 A10分别以直线 0为对称轴对称安装在本体 21的面向通道 22的 侧面上。 进一步地， 图 4b是根据本发明第二实施例的自动检票装置的立体图， 如图 4b所 示，在本体 21的在与通道的进入区和退出区分别对应的两侧的顶部斜面上，各安装有 一组检票单元 15和检票指示模块 182， 同时， 在本体 21的与图中所示的通行指示模 块 181所在面相对的背面上， 安装有另一通行指示模块（图中未标出）， 因此， 当本体 21面向通道 22的侧面上安装有如图 4a所示的 14个传感器 A1~A14时， 根据本发明 第二实施例的自动检票装置 200既可以以图 4a及图 4b中箭头 A所示方向为通行方向 (以下简称正向通行）， 也可以以与该方向相反的方向为通行方向 （以下简称反向通 行）。 当自动检票装置 200的通行方向为反向通行时， 通道 22的在正向通行时的进入 区变为反向通行时的退出区， 正向通行时的退出区变为反向通行时的进入区； 传感器 A12~A14用于判断通道的进入区中通行的需购票乘客的人数，传感器 All用于检测乘 客是否已离开通道的安全区，传感器 A4~A9仍用于检测通道的安全区中通行的乘客或 其携带物的状态。 下面以图 3a〜图 3c所示的根据本发明第一实施例的自动检票装置为例， 对自动检 票装置的检票方法进行说明。 图 5是根据本发明第一实施例的自动检票方法的流程图。 如图 5所示， 该方法包 括以下步骤： 步骤 Sll， 分别记录第一传感器、 第二传感器和第三传感器连续处于相同状态的 次数， 其中， 在乘客的通行方向上， 第一传感器、 第二传感器和第三传感器依次设置 在检票通道中。 第一传感器、 第二传感器和第三传感器可以为图 3所示的传感器 A1~A3。 该步骤中的状态可以是被遮挡状态， 也可以是不被遮挡状态。 因此， 连续处于相 同状态的次数是指任意一传感器连续处于被遮挡状态的次数或连续处于不被遮挡的次 数， 例如， 分别记录第一传感器连续处于被遮挡状态的次数， 第二传感器连续处于被 遮挡状态的次数和第三传感器连续处于被遮挡状态的次数。 优选地， 在对第一传感器、 第二传感器和第三传感器连续处于相同状态的次数分 别记录时， 可以是每间隔预设时间分别记录一次第一传感器、 第二传感器和第三传感 器的状态， 当任一传感器连续两次记录的状态相同时， 将该传感器的连续状态次数进 行加 1操作， 当任一传感器连续两次记录的状态不同时， 将该传感器的连续状态次数 进行置 1操作， 然后将该传感器连续处于当前状态的上一状态的次数存储至与该传感 器对应的第一数据集合中。 步骤 S12， 当检测到乘客到达第三传感器的位置时， 统计在设定时间段内记录的 第一传感器、 第二传感器和第三传感器连续处于相同状态的次数。 设定时间段可以为连续两次检测到有乘客到达第三传感器的位置的时刻之间的时 间段， 也可以为检测到乘客到达第三传感器的位置的时刻之前预设长度的时间段。 步骤 S13， 根据统计的结果计算在设定时间段内检票通道内需购票乘客的人数。 在该步骤中， 可以是根据对第一传感器、 第二传感器和第三传感器分别统计的结 果先分别计算第一传感器、 第二传感器和第三传感器检测到的检票通道内需购票乘客 的人数， 再根据第一传感器、 第二传感器和第三传感器检测到的检票通道内需购票乘 客的人数确定最终检测到的检票通道内需购票乘客的人数， 也可以是根据对第一传感 器、第二传感器和第三传感器分别统计的结果直接计算检票通道内需购票乘客的人数。 在该实施例中， 由于对多个传感器在设定时间段内处于相同状态的次数分别进行 统计， 并根据统计的结果计算在设定时间段内检票通道内需购票乘客的人数， 因而提 高了自动检票的准确性和可靠性。 优选地， 在根据第一传感器、 第二传感器和第三传感器检测到的检票通道内需购 票乘客的人数确定最终检测到的检票通道内需购票乘客的人数时， 可以按照以下任意 一种或者多种方法确定在设定时间段内检票通道内需购票乘客的人数： 当第一传感器、 第二传感器和第三传感器中任一传感器检测到的需购票乘客的人 数为 0时， 判定检票通道内需购票乘客的人数为 0。 当第一传感器、 第二传感器和第三传感器检测到的需购票乘客的人数一致时， 判 定检票通道内需购票乘客的人数为一致的人数。 当第一传感器、 第二传感器和第三传感器检测到的需购票乘客的人数存在两种情 况时， 将其中的两个检测结果一致的人数作为检票通道内需购票乘客的人数。 当第一传感器、第二传感器和第三传感器检测到的需购票乘客的人数各不相同时， 将三个传感器的检测结果的中间值作为检票通道内需购票乘客的人数。 在根据统计的结果计算检票通道内需购票乘客的人数时， 可以按照以下方法统计 每个传感器检测到的检票通道内需购票乘客的人数： 对第一数据集合中的数据进行去噪处理， 得到第二数据集合， 其中， 去噪处理包 括： 当第一数据集合 Cln中所存储的非零数据的个数大于三个时， 搜索第一数据集合 Cln中第一个非零数据和最后一个非零数据之间的最小数据 dnm并对其进行判断， 当 dnm小于第二预设阈值 N时， dnm及 (！^^被累加到 dn^上， dnm+2在第一数据集合 Cln 中的位置向前移动， 其序号变为 m， dnm+2后面的数据在第一数据集合 Cln中的位置 也依次向前移动， 第一数据集合 Cln中空出的最后两个序号的位置用零进行填充， 当 第一数据集合 Cln内的最小数据不小于第二预设阈值 N或第一数据集合 Cln内只剩余 三个非零数据时， 停止进行数据搜索及判断， n为传感器序号， 取值为 1、 2、 3， m为 Cln内数据的序号。 将第二数据集合中存储的表示每个传感器处于被遮挡状态的非零数据的个数作为 该传感器检测到的检票通道内需购票乘客的人数。 图 6是根据本发明的第二实施例的自动检票方法的流程图， 该方法适用于乘客按 照一人一票顺序通过检票装置的检票原则， 该方法包括以下步骤： 步骤 S21， 判断本次检测到的乘客提供的票纸是否有效 当检票单元检测到有乘客提供票纸时， 比如， 当票纸为 IC卡时， 检票单元检测到 乘客刷卡， 或者票纸为磁性票时， 检测单元检测到乘客插入票纸时， 检票单元读取乘 客提供的票纸的记录信息（以下简称票纸信息）， 并通过通信单元将所读取的票纸信息 上传到与自动检票装置连接的上位机， 上位机判断该票纸是否有效， 并将判断结果返 回给自动检票装置， 自动检票装置的通信单元接收上位机返回的该票纸是否有效的信 息， 当票纸有效时， 执行步骤 S23 ; 否则， 执行步骤 S22。 步骤 S22， 发出票纸无效报警 当检票单元检测到的乘客提供的票纸无效时， 进行票纸无效报警， 比如， 控制单 元控制检票指示模块发出票纸无效的指示信息， 同时控制报警模块发出票纸无效的报 警信息。 步骤 S23， 检测通道的进入区中需购票乘客的人数 当检测到的乘客提供的票纸有效时， 控制单元检测通道的进入区中需购票乘客的 人数。 控制单元每间隔预设时间记录一次通道的进入区中前三个传感器 A1~A3 的状 态，当传感器 A3连续多次处于被遮挡状态时控制单元判定有乘客到达传感器 A3所在 位置， 例如， 当传感器 A3在一段设定时间内连续处于被遮挡状态时控制单元判定有 乘客到达传感器 A3所在位置，当检测到有乘客到达传感器 A3所在位置时控制单元统 计在设定时间段内所记录的传感器 A1~A3的状态，根据统计结果计算该设定时间段内 通道的进入区中需购票乘客的人数， 其中， 设定时间段可以为连续两次检测到有乘客 到达传感器 A3所在位置的时刻之间的时间段， 当自动检票装置上电后首次有乘客到 达传感器 A3所在位置时， 该设定时间段可以为自动检票装置上电时刻到当前检测到 有乘客到达传感器 A3所在位置时刻之间的时间段， 当自动检票装置上电后非首次有 乘客到达传感器 A3所在位置时， 该设定时间段可以为控制单元上次检测到有乘客到 达传感器 A3所在位置到当前检测到有乘客到达传感器 A3所在位置时刻之间的时间 段； 另外， 该设定时间段也可以为检测到有乘客到达传感器 A3所在位置时刻之前预 设长度的时间段， 例如， Is或 2s。 步骤 S24， 判断通道的进入区中需购票乘客的人数是否大于 1 读取步骤 S23已经检测到通道的进入区中需购票乘客的人数， 判断设定时间段内 通道的进入区中需购票乘客的人数是否大于 1， 如果是， 执行步骤 S25， 否则， 执行步 骤 S26。 步骤 S25， 发出非法尾随过检报警 当在设定时间段内通道的进入区中需购票乘客的人数大于检票单元已经检测到的 有效票纸的数量 1时， 控制单元判定自动检票装置的通道的进入区中存在需要购买票 纸但没有提供有效票纸的乘客， 即通道的进入区中存在非法尾随过检的乘客， 控制单 元控制报警模块发出报警信息， 提示非法尾随过检的乘客需要提供有效票纸。 步骤 S26， 打开闸门 当在设定时间段内通道的进入区中需购票乘客的人数不大于检票单元已经检测到 的有效票纸的数量 1时， 控制单元控制闸门转动， 使其达到 180度位置， 处于打开状 态， 允许进入区中的乘客在通道中通行。 步骤 S27， 检测通道的安全区及退出区中乘客的状态， 当检测到乘客已离开通道 的安全区时， 关闭闸门 控制单元检测位于通道的安全区及退出区中的传感器 A4~A10的状态， 当控制单 元检测到传感器 A10处于被遮挡状态且传感器 A4~A9处于不被遮挡状态时， 控制单 元判定乘客已经离开通道的安全区进入通道的退出区，此时，控制单元控制闸门转动， 使其达到 90度位置， 处于关闭状态。 优选地， 为了避免前一乘客尚未离开闸门时后一乘客已进入通道， 造成检测结果 混淆， 当检票单元检测到有效票纸时， 控制单元禁止检票单元的检票功能直至打开的 闸门被关闭， 闸门被关闭后检票单元的检票功能被使能， 后续乘客可以继续提供有效 票纸， 在自动检票装置的通道中通行。 图 7是根据本发明的第三实施例的自动检票方法的流程图， 该方法适用于乘客按 照一人一票顺序通过检票装置的检票原则， 该方法包括以下步骤： 步骤 S31， 判断本次检测到的乘客提供的票纸是否有效 当检票单元检测到有乘客提供票纸时， 控制单元判断本次检测到的乘客提供的票 纸是否有效， 当票纸有效时， 执行步骤 S33 ; 否则， 执行步骤 S32。 步骤 S32， 发出票纸无效报警 同步骤 S22。 步骤 S33， 检测通道的进入区中需购票乘客的人数 同步骤 S23。 步骤 S34， 判断通道的进入区中需购票乘客的人数是否大于 1 判断设定时间段内通道的进入区中需购票乘客的人数是否大于检票单元已经检测 到的有效票纸的数量 1， 如果是， 执行步骤 S35， 否则， 执行步骤 S36。 步骤 S35， 发出非法尾随过检报警 同步骤 S25。 步骤 S36， 判断闸门是否为打开状态 控制单元检测闸门状态， 判断当前闸门是否为打开状态， 如果是， 执行步骤 S38; 否则， 执行步骤 S37。 步骤 S37， 打开闸门 控制单元控制闸门转动， 使其达到 180度位置， 处于打开状态。 步骤 S38， 检测通道的安全区及退出区中乘客的状态， 当检测到乘客已离开通道 的安全区时， 关闭闸门 同步骤 S27。 本实施例中， 允许后一乘客在前一乘客没有离开通道时进入通道的进入区， 如果 前一位乘客离开通道的安全区时后一位乘客已经进入通道的进入区， 此时控制单元不 再控制闸门关闭， 直接判断后一位乘客是否满足过检的要求， 当该乘客满足过检的要 求时， 允许乘客在通道中通行。 本实施例提供的检测方法在客流量较大的时候可以提 高自动检票装置的检票效率。 进一步地， 本发明提供的自动检票装置也可以按照由多位乘客中的首位乘客提供 多张票纸、 其后多位乘客顺次随该乘客进入通道的原则检票， 具体实现方法为： a)检测有效票纸的数量， 其中， 检票单元每检测到一张有效票纸后控制单元将存 储在 RAM存储器中的有效票纸数量进行加 1操作； b)检测通道的进入区中需购票乘客的人数，控制单元每间隔预设时间记录通道的 进入区中前三个传感器 A1~A3的状态， 当检测到有乘客到达传感器 A3所在位置时， 检测一设定时间段内通道的进入区中需购票乘客的人数， 并将存储在 RAM存储器中 的需购票乘客的人数累加本次检测到的通道的进入区中需购票乘客的人数； c)控制单元判断需购票乘客的人数是否大于有效票纸数量， 当需购票乘客人数不 大于有效票纸数量时， 控制闸门打开允许乘客在通道中通行； d)检测通道中退出安全区的需购票乘客的人数，控制单元检测通道的安全区及退 出区中乘客的状态， 当每检测到一位乘客离开通道的安全区进入通道的退出区时， 控 制单元将存储在 RAM存储器中的有效票纸数量及需购票乘客的人数分别进行减 1操 作。 需要说明的是， 在自动检票装置上电后的工作过程中， 步骤 a)和步骤 b)—直持 续被执行， 这样可以保证控制程序在执行步骤 c)及步骤 d)的过程中有效票纸的数量 及通道的进入区中需购票乘客的人数可以实时地被更新， 从而可以使自动检票装置关 闭闸门前如果检测到有效票纸的数量或通道的进入区中需购票乘客的人数增加时， 控 制程序可以不关闭闸门， 直接执行步骤 c)。 自动检票装置通过使用该自动检票方法， 在乘客提供的有效票纸的数量与需购票乘客的人数一致时， 允许乘客以任意形式在自 动检票装置的通道中通行， 提高了自动检票装置的检票效率， 同时， 使乘客的通行更 加便利。 图 8是根据本发明第一实施例的通道的进入区中需购票乘客的人数的检测方法的 流程图， 该方法包括以下步骤： 步骤 S51， 检测并记录通道的进入区中前三个传感器的状态， 同时记录每个传感 器连续处于同一状态的次数 控制单元每间隔预设时间检测通道的进入区中前三个传感器的光接收器的输出信 号， 比如， 控制单元每间隔预设时间 10ms， 检测每个传感器的光接收器的输出信号， 根据传感器的光接收器的输出信号确定并记录当前时刻传感器的状态， 设传感器被遮 挡时的状态用二进制 "1"表示， 传感器不被遮挡时的状态用二进制 "0"表示。 控制单元 每次记录当前传感器的状态前， 判断当前传感器状态与上一次记录的该传感器的状态 是否一致，如果相邻两次检测到的传感器的状态一致，传感器连续状态次数 SCnt_n (n 为传感器序号， 取值为 1、 2、 3 ) 进行加 1操作； 否则， 控制单元将传感器连续处于 上一状态的传感器连续状态次数 SCnt_n存储在与该传感器对应的第一数据集合 Cln (n为传感器序号， 取值为 1、 2、 3 ) 中， 并将传感器连续状态次数 SCnt_n置为" 1"。 图 9中示意了在一段时间内前三个传感器的状态的直观表示图像， 如图 9所示， 每一行的所有像素点表示相应的传感器在该段时间内的状态， 像素点为黑色表示检测 时刻传感器处于被遮挡状态， 像素点为白色表示检测时刻传感器处于不被遮挡状态。 箭头 t所示方向为时间发生的先后顺序， 沿箭头方向的前一个的像素点为先于其后的 像素点而检测的传感器的状态。 进一步地， 为便于统计， 第一数据集合 Cln中所存储的数据 dnm (n为传感器序 号， 取值为 1、 2、 3， m为 Cln内数据的序号， 取值为正整数） 是按一定规则进行排 放的， 比如， 序号为奇数的数据为传感器连续处于不被遮挡状态的次数， 序号为偶数 的数据为传感器连续处于被遮挡状态的次数， 当第一次记录的传感器的状态为被遮挡 状态时， 可设置该传感器相对应的第一数据集合 Cln的第一个数据为 0， 即传感器连 续处于不被遮挡状态的次数为 0， 在传感器状态首次发生变化时将传感器连续状态次 数 SCnt_n，即传感器连续处于被遮挡状态的次数存储为第一数据集合 Cln的第二个数 据。 步骤 S52， 判断进入区中第三个传感器连续处于被遮挡状态的次数是否达到第一 预设阈值 M 当传感器 A3当前次的状态为被遮挡状态， 即为" 1"状态时， 控制单元将第三个传 感器连续状态次数 SCnt_3进行加 1操作后与第一预设阈值 M进行比较， 判断传感器 A3连续处于被遮挡状态的次数是否达到 M次， 如果是， 执行步骤 S53， 否则， 执行 步骤 S51。 设第一预设阈值 M为 10， 图 9中所示意的 T2和 T3时刻均为第三个传感器 连续处于被遮挡状态的次数达到 Μ次的时刻。 步骤 S53， 对每个传感器的第一数据集合 Cln进行去噪处理 当传感器 A3连续处于被遮挡状态的次数达到第一预设阈值 M时， 对设定时间段 内第一数据集合 Cln中所存储的数据进行去噪处理， 其中， 当自动检票装置上电后传 感器 A3连续处于被遮挡状态的次数首次达到第一预设阈值 M时， 所述设定时间段为 自动检票装置上电时刻到当前时刻之间的时间段， 如图 9中所示意的 时刻到 T2时 刻之间的时间段； 否则， 所述设定时间段为上次传感器 A3连续处于被遮挡状态的次 数达到第一预设阈值 Μ时刻到当前次传感器 A3连续处于被遮挡状态的次数达到第一 预设阈值 Μ时刻之间的时间段， 比如， 图 9中所示意 Τ2时刻到 Τ3时刻之间的时间段。 控制单元对第一数据集合 Cln中设定时间段内所存储的数据采用如下规则进行去 噪处理： 当第一数据集合 Cln中所存储的非零数据的个数大于三个时， 搜索第一数据 集合 Cln 中第一个非零数据和最后一个非零数据之间的最小数据 dnm并对其进行判 断， 当 dnm小于第二预设阈值 N时， dnm及 (！^^被累加到 dtim^上， dnm+2在第一数据 集合 Cln中的位置向前移动， 其序号变为 m， dnm+2后面的数据在第一数据集合 Cln 中的位置也依次向前移动， 第一数据集合 Cln中空出的最后两个序号的位置用零进行 填充， 当第一数据集合 Cln内的最小数据不小于第二预设阈值 N或第一数据集合 Cln 内只剩余三个非零数据时， 停止进行数据搜索及判断。 对每个传感器的第一数据集合 Cln进行数据处理后得到的一组新的数据， 该组数 据被存储在与该传感器相对应的第二数据集合 C2n (n为传感器序号，取值为 1、 2、 3 ) 中， 即第二数据集合 C2n中存储数据的为第一数据集合 Cln进行去噪处理后得到相应 传感器连续处于被遮挡状态的次数和 /或传感器连续处于不被遮挡状态的次数。 表 la为根据图 9所示意的前三个传感器的状态在 时刻到 T2时刻之间的时间段 内第一数据集合 Cln中的数据。 表 la
Figure imgf000020_0001
设第二预设阈值 N=30，对表 la所示的第一数据集合 Cln中的数据进行去噪处理， 由于 C11中所存储的非零数据的个数为两个， 因此， C11中的数据不需要进行去噪处 理； C12中对应的序号为 1~6的 6个数据分别为 {14、 8、 20、 32、 2、 0} , 其中， 第一 个非零数据 (12^14， 最后一个非零数据为 d25=2， 对 (121与(125之间的最小数据进行搜 索， 得到最小数据为 d22=8， 且 d22小于第二预设阈值 N， 因此， 将 d22、 d 合并到 上， 得到 (12^42， C12的 d23之后的数据依次向前移动两个位置， 空出的最后两个 序号的位置用 0进行填充， 即对 C12中的数据进行去噪处理后得到对应的第二数据集 合 C22中对应的序号为 1~6的 6个数据分别为 {42、 32、 2、 0、 0、 0}。 按照上述方法 对 C13中的数据进行去噪， 得到表 lb所示的第二数据集合 C2n。 表 lb

表 2a为根据图 9所示意的前三个传感器的状态在 T2时刻到 Τ3时刻之间的时间段 一数据集合 Cln中的数据。 表 2a
Figure imgf000021_0001
设第二预设阈值 N=30，对表 2a所示的第一数据集合 Cln中的数据进行去噪处理， 得到表 2b所示的第二数据集合 C2n。 表 2b
Figure imgf000021_0002
需要说明的是， 在完成对第一数据集合 Cln的去噪处理后， 每个传感器对应的新 生成的数据存储与其对应的第二数据集合 C2n中，此时，控制单元将第一数据集合 Cln 清空， 第一数据集合 Cln可以继续用于存储后续统计的相应传感器连续处于被遮挡状 态的次数和 /或传感器连续处于不被遮挡状态的次数。 本步骤通过对第一数据集合 Cln进行去噪处理，将第一数据集合 Cln中小于第二 预设阈值 N的非零数据与该数据前面的非零数据合并， 就可以将传感器在一个较短时 间内的不稳定状态过滤掉， 比如， 在步骤 S51中每间隔 10ms记录一次传感器的状态， 当第二预设阈值 N=30时， 被合并的非零数据表示相应的传感器在一个小于 300ms的 设定时间段内连续处于被遮挡状态或不被遮挡状态， 这种状态被认为是传感器的不稳 定状态， 比如由于乘客胳膊的摆动、 乘客携带行李箱的行李杆的移动等造成的传感器 的状态变化， 本步骤通过合并非零数据过滤传感器的不稳定状态， 因此， 新生成的第 二数据集合 C2n中存储的非零数据可以表示相应传感器在一个时间段内处于一个稳定 的状态。 步骤 S54， 统计通道的进入区中需购票乘客的人数 由于第二数据集合 C2n中存储的非零数据表示相应传感器在一个时间段内处于一 个稳定的被遮挡状态和 /或不被遮挡状态， 因此， 第二数据集合 C2n中存储的表示传感 器连续处于被遮挡状态的非零数据即可表示在一个时间段内有一位乘客经过该传感器 所在位置， 控制单元根据第二数据集合 C2n中表示传感器连续处于被遮挡状态的非零 数据的数量判断每一个传感器检测到在设定时间段内通道的进入区中需购票乘客的人 数， 第 n个传感器对应的第二数据集合 C2n中存储的表示传感器连续处于被遮挡状态 的非零数据的个数即为该传感器所检测到的在该设定时间段内通道的进入区中需购票 乘客的人数， 比如， 表 lb所示的第二数据集合 C21、 C22、 C23中表示传感器连续处 于被遮挡状态的非零数据的个数均为 1， 即数据集合 C21中 dl2=49， 数据集合 C22中 d22=43， 数据集合 C23中 d32=10， 因此， 在 时刻到 T2时刻之间的时间段内， 传感 器 Α1~Α3检测到的通道的进入区中需购票乘客的人数均为 1个； 同理， 从表 2b中可 以得知， 在 T2时刻到 T3时刻之间的时间段内， 传感器 Al、 Α2检测到的通道的进入 区中需购票乘客的人数均为 1个， 传感器 A3检测到的通道的进入区中需购票乘客的 人数为 2个。 对前三个传感器检测到的需购票乘客的人数采用一定的规则进行计算， 确定在设 定时间段内通道的进入区中的最终需购票乘客的人数， 计算规则为： 当任一个传感器 检测到的需购票乘客的人数为 0时， 判定通道内的最终需购票乘客的人数为 0; 当三 个传感器检测到的需购票乘客的人数均不为 0时， 若三个传感器检测到的需购票乘客 的人数一致， 则判定该乘客人数为通道内的最终需购票乘客的人数； 若三个传感器检 测到的需购票乘客的人数有两种情况， 则判定其中的两个检测结果一致的传感器检测 到的需购票乘客的人数为通道内的最终需购票乘客的人数； 若三个传感器的检测到的 需购票乘客的人数各不相同， 则对三个传感器的检测结果进行排序， 取中间值作为通 道内的最终需购票乘客的人数。 比如， 在 时刻到 τ2时刻之间的时间段内， 传感器 Α1~Α3检测到的通道的进入区中需购票乘客的人数均为 1个， 因此， 控制单元判定在 时刻到 Τ2时刻之间的时间段内通道的进入区中需购票乘客的人数为 1个； 再比如， 在 Τ2时刻到 Τ3时刻之间的时间段内， 传感器 Al、 Α2检测到的通道的进入区中需购 票乘客的人数均为 1个， 传感器 A3检测到的通道的进入区中需购票乘客的人数为 2 个， 因此， 控制单元判定在 Τ2时刻到 Τ3时刻之间的时间段内通道的进入区中需购票 乘客的人数为 1个。 本发明对于通道进入区中最终需购票乘客的人数的计算规则不局 限于上述规则。 本发明实施例提供的自动检票装置及自动检票方法， 在第三个传感器处于一个比 较稳定的被遮挡状态时启动通道的进入区中需购票乘客的人数的判断， 通过检测在该 判定时刻前的一个满足设定要求的设定时间段内前三个传感器的稳定状态确定该设定 时间段内通道的进入区中需购票乘客的人数， 由于乘客或其携带物在该设定时间段内 连续移动时必定会依次经过传感器的安装位置， 因此， 本发明通过检测该设定时间段 内传感器的稳定状态判断该设定时间段内经过每个传感器的需购票乘客的人数， 进而 判断该设定时间段内通道的进入区中需购票乘客的人数， 能够准确、 可靠地检测出该 时间段内通道的进入区中需购票乘客的人数，进而提高了自动检票的准确性和可靠性。 相应于上述的自动检票方法， 本发明实施例还提供了一种自动检票装置。 需要说 明的是， 该自动检票装置可以执行本发明实施例所提供的自动检票方法， 本发明实施 例的检票方法也可以通过本发明实施例所提供的自动检票装置来执行。 以下结合图 10 至图 12对该种自动检票装置进行描述： 图 10是根据本发明第二实施例的自动检票装置的示意图。 该自动检票装置包括： 记录单元 10， 用于分别记录第一传感器、 第二传感器和第三传感器连续处于相同 状态的次数， 其中， 在乘客的通行方向上， 第一传感器、 第二传感器和第三传感器依 次设置在检票通道中； 统计单元 20， 用于当检测到乘客到达第三传感器的位置时， 统计在设定时间段内 记录的第一传感器、 第二传感器和第三传感器连续处于相同状态的次数。 计算单元 30， 用于根据统计的结果计算设定时间段内检票通道内需购票乘客的人 数。 优选地，计算单元 10用于首先根据统计的结果分别计算第一传感器、第二传感器 和第三传感器检测到的需购票乘客的人数， 然后按照以下任意一种或者多种方法确定 在设定时间段内检票通道内需购票乘客的人数，其中，计算单元 10包括以下任意一个 或多个计算单元 （图上未示出）。 第一计算单元， 用于当第一传感器、 第二传感器和第三传感器中任一传感器检测 到的需购票乘客的人数为 0时， 判定检票通道内需购票乘客的人数为 0。 第二计算单元， 用于当第一传感器、 第二传感器和第三传感器检测到的需购票乘 客的人数一致时， 判定检票通道内需购票乘客的人数为一致的人数。 第三计算单元， 用于当第一传感器、 第二传感器和第三传感器检测到的需购票乘 客的人数存在两种情况时， 将其中的两个检测结果一致的人数作为检票通道内需购票 乘客的人数。 第四计算单元， 用于当第一传感器、 第二传感器和第三传感器检测到的需购票乘 客的人数各不相同时， 将三个传感器的检测结果的中间值作为检票通道内需购票乘客 的人数。 图 11是根据本发明第三实施例的自动检票装置的示意图。该实施例的自动检票装 置可以作为图 10所示实施例的自动检票装置的一种优选实施方式： 其中， 记录单元 10包括： 记录模块 101， 用于每间隔预设时间分别记录一次第一传感器、 第二传感器和第 三传感器的状态； 更新单元 102， 用于当任一传感器连续两次记录的状态相同时， 将该传感器的连 续状态次数进行加 1操作， 当任一传感器连续两次记录的状态不同时， 将该传感器的 连续状态次数置 1 ; 以及 存储单元 103， 用于当任一传感器连续两次记录的状态不同时， 将该传感器连续 处于当前状态的上一状态的次数存储至与该传感器对应的第一数据集合中， 其中， 计算单元 30包括： 去噪模块 301， 用于对第一数据集合中的数据进行去噪处理， 得到第二数据集合， 其中， 去噪处理包括： 当第一数据集合 Cln中所存储的非零数据的个数大于三个时， 搜索第一数据集合 Cln中第一个非零数据和最后一个非零数据之间的最小数据 dnm并 对其进行判断， 当 dnm小于第二预设阈值 N时， dnm及 dnm+1被累加到 dn^上， dnm+2 在第一数据集合 Cln中的位置向前移动， 其序号变为 m， dnm+2后面的数据在第一数 据集合 Cln中的位置也依次向前移动，第一数据集合 Cln中空出的最后两个序号的位 置用零进行填充，当第一数据集合 Cln内的最小数据不小于第二预设阈值 N或第一数 据集合 Cln内只剩余三个非零数据时， 停止进行数据搜索及判断， n为传感器序号， 取值为 1、 2、 3， m为 Cln内数据的序号。 确定模块 302， 用于将第二数据集合中存储的表示每个传感器处于被遮挡状态的 非零数据的个数作为该传感器检测到的检票通道内需购票乘客的人数。 图 12是根据本发明第四实施例的自动检票装置的示意图。该实施例的自动检票装 置除了包括图 10所示自动检票装置的各个部分之外， 还包括： 检测单元 40， 用于在接收到多张票纸时， 检测多张票纸中有效票纸的数量。 判断单元 50， 用于在根据统计的结果计算检票通道内需购票乘客的人数之后， 判 断检票通道内需购票乘客的人数是否大于有效票纸的数量。 控制单元 60， 用于当判断出检票通道内需购票乘客的人数不大于有效票纸的数量 时， 控制闸门打开以允许乘客在检票通道中通行。 显然， 本领域的技术人员应该明白， 上述的本发明的各单元、 模块或各步骤可以 用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算 装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 或者将它们分别制作成各个集成电 路模块， 或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本 发明不限制于任何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
