具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
实施例一
本申请实施例一提供了一种空间拥挤度的检测方法，图1为本申请实施例一提供的一种空间拥挤度的检测方法的流程图，如图1所示，该方法包括如下步骤：
S110、向一空间发射第一无线波信号，空间被划分为至少两个检测区间，空间用于承载目标对象。
其中，空间可以是基本没有人工构筑物覆盖的开放空间，例如，广场、运动场、物料场地或水域等，也可以是非开放空间，例如室内空间、候车大厅、地铁站或电梯轿厢等，本申请在此不做限定。空间用于承载目标对象，目标对象可以是人、动物、货物。无线波信号可以由无线检测器发出，无线检测器可以是雷达。一实施例中，可以是毫米波雷达，毫米波雷达检测具有高分辨率、高敏感度和检测距离远等优势。无线波信号也可以是其他的形式，例如超声波信号、激光信号等，本申请在此不做限定。该空间被划分为至少两个检测区间，示例性的，以无线检测器为球心，沿信号传播方向，将该空间划分为多个等距的检测区域。
S120、接收第二无线波信号，第二无线波信号为第一无线波信号经目标对象反射后生成的无线波信号。
第一无线波信号经目标对象反射后，生成第二无线波信号，并被无线检测器接收。
在具体实施例中，在开放空间内，可能存在长期放置的物体，例如广场中 的雕塑等，非开放空间存在墙壁、座椅或摆设，这些空间静物或墙壁对第一无线波信号也会产生反射，为了避免这些空间静物或墙壁的反射波对回波反射强度的影响，可预先针对该空间发射第一无线波信号，记录回波频谱特征，频谱特征用于表示空间中静物的特征。
在接收到第二无线波信号之后，可获取预设的频谱特征，从第二无线波信号中剔除与频谱特征匹配的无线波信号。
在空间处于空闲状态时，获取反射波的频谱特征，该频谱特征用于表示空间中静物的特征，从第二无线波信号中剔除与频谱特征匹配的无线波信号，进而消除空间静物或墙壁的反射波对回波反射强度的影响。
S130、基于第一无线波信号和第二无线波信号，确定目标对象在空间中所处的位置。
可选的，可以根据第一无线波信号和第二无线波信号的频率差或相位差，确定目标对象在空间中所处的位置。
可选的，在空间中设置有一无线检测器，无线检测器用于发射第一无线波信号，以及，接收第二无线波信号。一实施例中，无线检测器为调频连续波(Frequency Modulated Continuous Wave，FMCW)雷达。
在一种可选的实施方式中，S130可以包括如下步骤：
S131、计算第一无线波信号和第二无线波信号之间的频率差。
S132、基于频率差确定目标对象距离无线检测器的距离，作为目标对象在空间中所处的位置。
图2为本申请实施例中调频连续波雷达发射的第一无线波信号的波形图，图3为图2中的第一无线波信号的频率随时间的变化图，如图2和图3所示，调频连续波雷达发射的雷达波，即第一无线波信号的频率随着时间线性增加，增加的速度(斜率)为K，频率增加的周期(扫频周期)为T c。图4为第一无线波信号和第二无线波信号的频率随时间的变化图，如图4所示，当第一无线波信号TX chirp遇到目标对象被反射回来后，无线检测器接收到的第二无线波信号RX chirp的频率也会同样随着时间线性增加。由于第二无线波信号需要一定距离才能回到接收天线，因此接收的第二无线波信号相比发射的第一无线波信号有一定的延时，接收的电磁波的频率变化与发射的电磁波的频率变化之间同样存在延时τ，接收的第二无线波信号与发射的第一无线波信号之间存在频率差：
Sτ＝K*τ    (1)
其中，τ＝2d/c，d为目标对象距离无线检测器的距离，为未知量，c为光速。那么上述式(1)可以变换为：
Sτ＝K*2d/c    (2)
假设第一无线波为：
Figure PCTCN2020085256-appb-000001
第二无线波为：
Figure PCTCN2020085256-appb-000002
设计一个混频器，第一无线波信号和第二无线波信号输入混频器，经混频器混频处理，输出混频信号x out：
Figure PCTCN2020085256-appb-000003
对于任意时域信号，经过傅里叶变换后，可以获得其频域特性。图5为对正弦波进行傅里叶变换后的频域特性，如图5所示，对于正弦波，其傅里叶变换后，频域特性为在其频率点具有很高的幅值，其它频率则快速下降。
图6为对混频信号进行傅里叶变换后的频域特性，如图6所示，由于第一无线波信号和第一无线波信号的频率存在差值，因此傅里叶波形会具有两个峰值，因此，可以根据混频信号傅里叶变换后的频域特性，提取出第一无线波信号和第一无线波信号的频率差Sτ，因此在上述式(2)中，Sτ、K和c均为已知量，进而可以求出目标对象距离无线检测器的距离d，将目标对象距离无线检测器的距离d，结合信号发射角度和反射角度，确定目标对象在空间中所处的位置。
S140、根据位置确定目标对象在空间中所处的检测区间。
根据目标对象距离无线检测器的距离，确定目标对象在空间中所处的位置之后，根据该位置在空间中所处的检测区间，确定目标对象在空间中所处的检测区间。
可选的，在一实施例中，检测区间关联检测范围，检测范围以无线检测器为基准点。
S140可以包括如下步骤：
S141、确定包含距离的检测范围。
S142、将检测范围设置为目标对象在空间中所处的检测区间。
S150、基于第二无线波信号的回波反射强度，确定检测区间中目标对象的拥挤度。
检测区间中目标对象越多，无线检测器接收的第二无线波信号的回波反射 强度越大，因此，可以根据回波反射强度，确定检测区间中目标对象的拥挤度。
可选的，基于第二无线波信号的回波反射强度，确定检测区间中目标对象的拥挤度，包括：
若回波反射强度大于预设的阈值，则确定检测区间中目标对象的拥挤度为饱和状态。一实施例中，可以根据实际需求和预先试验设定阈值，若某一检测区间内目标对象对应的回波反射强度大于预设的阈值，则确定该检测区间中目标对象的拥挤度为饱和状态。根据各检测区间的目标对象的拥挤度，进行相应的业务操作，示例性的，在确定广场、候车大厅等空间的某一检测区间已处于人员饱和状态时，及时发布提示信息，将人流引至其他非饱和检测区间，提高广场的空间利用率，同时避免出现踩踏事件。示例性的，在确定物料场地等空间的某一检测区间已处于物料饱和状态时，及时发布提示信息，将运送物料的物料车引至其他非饱和检测区间，提高工作效率和物料场地的空间利用率。
可选的，基于第二无线波信号的回波反射强度，确定检测区间中目标对象的拥挤度，还包括：
在至少两个强度范围中确定回波反射强度所处的强度范围，作为目标强度范围，每个强度范围关联拥挤度；将目标强度范围关联的拥挤度设置为检测区间中目标对象的拥挤度。
示例性的，可以根据实际需求，设置多个回波反射强度阈值，多个强度阈值形成多个强度范围，每个强度范围关联拥挤度。根据回波反射强度，确定回波反射强度所处的强度范围，并将该强度范围作为目标强度范围，根据目标强度范围关联的拥挤度，确定检测区间中目标对象的拥挤度。图7为本申请实施例的强度阈值设置和接收到的回波强度的图谱，图8为目标对象在空间内的一种分布图，图9为目标对象在空间内的另一种分布图，图10为目标对象在空间内的又一种分布图，图11为目标对象在空间内的又一种分布图，如图7-11所示，空间为以无线检测器为球心的扇形区域，扇形区域被划分为四个以无线检测器为圆心的同心环的检测区间，距离无线检测器由近到远分别为监测区间W、X、Y和Z，相邻检测区间的间距为0.5米。设置三个强度阈值，由小到大分别为A、B和C，从而形成四个强度范围，分别对应的拥挤度为空闲、较低、中等和饱和。图8中目标对象的分布对应图7中的曲线a，各检测区间的回波反射强度都在强度阈值A和B之间，各检测区间内目标对象的拥挤度大致相同，各检测区间的拥挤度较低；图9中目标对象的分布对应图7中的曲线b，各检测区间的回波反射强度都处于强度阈值B和C之间，各检测区间内目标对象的拥挤度大致相同，各检测区间的拥挤度为中等拥挤度；图10中目标对象的分布对应图7中的曲线c，各检测区间的回波反射强度都大于强度阈值C，各检测区间内目标对象的拥 挤度大致相同，各检测区间的拥挤度都处于饱和状态；图11中目标对象的分布对应图7中的曲线d，检测区间W和Y的回波反射强度都大于强度阈值C，即检测区间W和Y内目标对象的拥挤度大致相同处于饱和状态，检测区间X和Z的回波反射强度都小于强度阈值A，即检测区间X和Z内没有目标对象，处于空闲状态。
在开放空间内，可能存在长期放置的物体，例如广场中的雕塑等，非开放空间存在墙壁、座椅或摆设，这些空间静物或墙壁对第一无线波信号也会产生反射，为了避免这些空间静物或墙壁的反射波对回波反射强度的影响，可选的，在接收第二无线波信号之后，还包括：
获取预设的频谱特征，频谱特征用于表示空间中静物的特征；从第二无线波信号中剔除与频谱特征匹配的无线波信号。
在空间处于空闲状态时，获取反射波的频谱特征，该频谱特征用于表示空间中静物的特征，从第二无线波信号中剔除与频谱特征匹配的无线波信号，进而消除空间静物或墙壁的反射波对回波反射强度的影响。

实施例二
电梯是现代生活中经常使用的电器，但是电梯的控制方法存在很多不尽如人意的地方。比如写字楼使用电梯时，只有在电梯的实际载重达到额定载重时，才在每层楼的显示屏上显示满载，并不在任何楼层停靠，除非有人要下电梯。但是在实际使用过程中，常常出现电梯的实际载重还没有达到额定载重但是非常接近额定载重的情况，此时电梯仍旧会在每个存在外召的楼层停靠，但是由于电梯轿厢内实际拥挤度已经很高，门开后大部分候梯人员会选择不上电梯，即电梯会在各层进行停靠开门，但是又没人上电梯，因此不仅会大幅影响电梯的使用效率，而且延长了电梯内人员的乘梯时间，从而影响用户的乘梯感受。
本申请实施例二提供了一种电梯轿厢的调度方法，图12为本申请实施例二提供的一种空间拥挤度的检测方法的流程图，如图12所示，该方法包括如下步骤：

S220、在轿厢中接收第二无线波信号，第二无线波信号为第一无线波信号经乘梯对象反射后生成的无线波信号，第二无线波信号具有回波反射强度。

S242、将检测范围设置为乘梯对象在轿厢中所处的检测区间。
S250、基于第二无线波信号的回波反射强度，确定检测区间中乘梯对象的拥挤度。
检测区间中乘梯对象越多，无线检测器接收的第二无线波信号的回波反射强度越大，因此，可以根据回波反射强度，确定检测区间中乘梯对象的拥挤度。
可选的，基于第二无线波信号的回波反射强度，确定检测区间中乘梯对象的拥挤度，包括：
若回波反射强度大于预设的阈值，则确定检测区间中乘梯对象的拥挤度为饱和状态。一实施例中，可以根据实际需求和预先试验设定阈值，若某一检测区间内乘梯对象对应的回波反射强度大于预设的阈值，则确定该检测区间中乘梯对象的拥挤度为饱和状态。
可选的，基于第二无线波信号的回波反射强度，确定检测区间中乘梯对象的拥挤度，还包括：
在至少两个强度范围中确定回波反射强度所处的强度范围，作为目标强度范围，每个强度范围关联拥挤度；将目标强度范围关联的拥挤度设置为检测区间中乘梯对象的拥挤度。
一实施例中，检测区间中乘梯对象的拥挤度的确定可以参考实施例一中检测区间中目标对象的拥挤度的确定和图7-11，在此不再赘述。
S260、根据拥挤度调度轿厢。
示例性的，若该轿厢内各检测区间的拥挤度都为饱和状态，当某一楼层有外部召梯人员请求外召时，电梯控制系统控制该电梯轿厢不响应外部召梯人员的外召请求，避免电梯开门后，呼梯人员看见轿厢处于饱和状态而选择不上电梯的情况，提高电梯的使用效率，缩短了电梯内人员的乘梯时间，从而提高了 用户的乘梯体验。
本申请实施例提供的电梯轿厢的调度方法，通过无线波信号确定轿厢内乘梯对象在轿厢中所处的位置，根据位置确定乘梯对象在轿厢中所处的检测区间，并基于该检测区间内乘梯对象反射的第二无线波信号的回波反射强度，确定检测区间中乘梯对象的拥挤度，进而能够根据检测区间中乘梯对象的拥挤度及时发布控制指令或提示信息，对电梯轿厢进行相应的调度，提高电梯的利用率，缩短乘梯人员的乘梯时间，提高乘梯人员的乘梯体验。
示例性的，在本申请另一实施例中，各楼层的电梯层门附近的墙壁上，设置有外设设备，外设设备可以包括提示设备和召梯取消按钮，提示设备实时显示轿厢内的拥挤度情况，例如当前轿厢处于空闲、较低拥挤度、中等拥挤度或饱和状态，外部召梯人员可以根据轿厢内的拥挤度选择是否召梯。
示例性的，例如在提示设备显示轿厢处于饱和状态，且轿厢内乘梯人员均需要下到一层时，位于中间楼层需要下楼的外部召梯人员可以选择不请求外召，或者通过召梯取消按钮将已存在的外召请求取消掉。这样，电梯轿厢将不在外部召梯人员所在的楼层停留开门，直接将轿厢内乘梯人员送至一层，缩短了轿厢内乘梯人员乘梯时间，提高了乘梯体验，同时，由于中间楼层无需停留，也减少了侯梯人员的侯梯时间，提高了电梯的使用效率。
在实际的电梯运行系统中，存在一个电梯控制系统控制多个电梯的情况，可选的，根据拥挤度调度轿厢，包括：
接收一楼层的电梯外召操作；根据拥挤度从多个轿厢中选择目标轿厢，目标轿厢中存在至少一个检测区间中乘梯对象反射的第二无线波信号的回波反射强度小于预设的阈值；响应电梯外召操作，将目标轿厢调度至该楼层。
电梯控制系统获取各电梯轿厢内的拥挤度情况，在接收某一楼层的外部召梯人员的外召请求时，根据拥挤度从多个轿厢中选择目标轿厢，目标轿厢中存在至少一个检测区间中乘梯对象反射的第二无线波信号的回波反射强度小于预设的阈值，即至少存在一个检测区间处于非饱和状态。电梯控制系统响应外部召梯人员的外召请求，将目标轿厢调度至该楼层。
