具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种自动规划无线信号采集位置的方法，参照图1，在一实施例中，所述自动规划无线信号采集位置的方法包括：
步骤S10，确定采集区域的起始点，并基于所述起始点实时采集终端移动过程中的移动参数以及无线信号参数；
本实施例的自动规划无线信号采集位置的方法适用于通过自动控制采集终端在室内区域移动过程中移动轨迹的有效性，来采集多个不同位置的移动参数和无线信号参数，以根据移动参数和无线信号参数形成封闭轨迹图，此封闭轨迹图对应的移动区域即为无线信号的有效采集位置。具体的，需要规划采集位置的室内区域可以是大型商场内的各个店铺，也可以是小区的各个住户，或者是社区商店等覆盖有无线信号的区域，其中无线信号为WIFI信号，而此类室内环境区域为采集区域。终端则是如图7所示的具有用于采集移动参数的移动信息捕捉模块、用于采集无线信号参数的无线信号捕捉模块以及用于与服务器通信的通信模块的移动终端，其可以是智能手机、也可以是平板电脑等，对此不做限制。可理解地，采集区域有开始进行采集操作的起点位置，此起点位置为终端在采集区域移动的起始点，确定采集区域的起始点，终端则以此起始点开始在采集区域移动，且沿着采集区域的边界移动，如墙壁或隔断等，形成终端移动轨迹。基于此起始点实时采集终端移动过程中的移动参数以及无线信号参数。终端在采集区域移动，其移动轨迹随着时间而变化，从而实时采集终端移动过程中的移动参数和无线信号参数，以使根据移动参数和无线信号参数生成的移动轨迹图体现采集区域的范围。
步骤S20，将所述移动参数和无线信号参数上传到服务器，以供服务器根据所述移动参数和无线信号参数绘制移动轨迹图；
更进一步地，在实时采集终端移动过程中的移动参数和采集区域的无线信号参数后，将此实时采集的移动参数和无线信号参数以固定频率的方式上传到服务器，服务器建立有信号指纹库，将接收的移动参数和无线信号参数存储至信号指纹库中，并根据此移动参数和无线信号参数绘制移动轨迹图。其中移动参数包括移动速度和方向角，终端中的移动信息捕捉模块获取终端移动过程中的移动速度以及指南针角，并将指南针角转换为方向角。移动速度表征终端移动的快慢，方向角为N-E方向角，在N-E坐标系中，以正北方向为0弧度，射线从沿顺时针方向转过的角度对360取模运算后的结果，逆时针方向为负值。N-E坐标系为在正北-正东方向建立的垂直坐标系中，N轴正方向为正北方向，E轴正方向为正东方向。无线信号参数为采集区域中WIFI信号的MAC地址（media access control address，媒体访问控制、硬件地址身份标识）、SSID（Service Set Identifier，服务集标识）和RSSI（Received Signal Strength，接收到的信号强度）。服务器根据实时接收的移动参数绘制终端移动轨迹，通过检测终端在采集区域移动轨迹的有效性，以确保采集点的有效性，提高了终端在采集区域的信号采集质量的有效性，即实现通过移动轨迹的有效性来提高采集结果的有效性。
步骤S30，当检测到终端的当前采集点与起始点重合时，在服务器基于所述移动轨迹图形成封闭轨迹图，将所述封闭轨迹图对应的移动区域确定为无线信号的有效采集位置。
更进一步地，本实施例通过移动轨迹图体现采集区域的范围，当移动轨迹封闭时，此封闭区域即可表征采集区域的范围。从而当终端的当前采集点与起始点重合时，则说明终端移动轨迹形成封闭区域，当前采集点为终点位置。因终端沿着采集区域的边界移动，从而设定起始位置和终点位置为同一个出入口，终端从出入口开始沿着采集区域的边界移动，绕采集区域一周后，再从采集区域的同一个出入口出去，终端移动轨迹形成采集区域的封闭轨迹。相应的，当检测到终端的当前采集点与起始点重合，终端移动轨迹形成封闭曲线时，服务器根据实时上传的移动参数和无线信号绘制的移动轨迹图形成封闭轨迹图，将此封闭轨迹图对应的终端移动区域确定为无线信号的有效采集位置。
本实施的自动规划无线信号采集位置的方法，通过确定采集区域的起始点，以基于此起始点实时采集终端移动过程中的移动参数和无线信号参数，并将采集的移动参数和无线信号参数上传到服务器，服务器根据接收的移动参数和无线信号参数绘制移动轨迹图；而当检测到终端移动的当前采集点与起始点重合时，则说明终端移动轨迹为闭合曲线，相应的服务器绘制的移动轨迹图为封闭轨迹图，将此封闭轨迹图对应的终端移动区域确定为无线信号有效采集位置。本方案根据从终端移动过程中采集的移动参数和无线信号参数确定有效采集位置，不依赖电子图片打点，并通过服务器检测终端在采集区域移动轨迹的有效性，来确保采集点的有效性，使规划的有效采集位置更精确。
进一步地，在本发明自动规划无线信号采集位置的方法另一实施例中，所述移动参数包括移动速度和方向角，
所述基于所述起始点实时采集终端移动过程中的移动参数以及采集区域的无线信号参数的步骤包括：
从所述起始点开始，每间隔预设采集时间对终端移动过程中的当前移动速度、当前方向角以及当前无线信号参数进行采集。
进一步地，本实施例预先设定有预设采集时间，且预设采集时间的数值设置在合理范围内，避免太短使采集的数据过多，或者太长使采集的数据过少，不能体现采集区域的范围。从起始点开始，每间隔此预设采集时间时，对终端移动过程中的当前移动参数和当前无线信号进行采集，即采集终端的当前移动速度和当前方向角，以及当前无线信号参数。将此按预设采集时间采集的当前移动参数和当前无线信号上传到服务器，相应的服务器接收到两次当前移动参数和当前无线信号的时间，即为预设采集时间。将接收到的当前移动速度作为预设采集时间内的平均速度，从而根据此预设采集时间以及当前移动速度，可确定终端在预设采集时间内的位移大小，服务器通过位移大小和方向角即可在N-E坐标系上绘制对应的移动轨迹图。
进一步地，请参照图2，在本发明自动规划无线信号采集位置的方法第一实施例的基础上，提出本发明自动规划无线信号采集位置的方法第二实施例，在第二实施例中，所述当检测到终端的当前采集点与起始点重合时的步骤之前包括：
步骤S40，判断终端的当前采集点是否到达起始点，当终端的当前采集点到达起始点时，判断终端在当前采集点的停留时间是否大于预设时间；
步骤S50，当终端在当前采集点的停留时间大于预设时间时，判定终端的当前采集点与起始点重合。
更进一步地，每个采集区域有其对应的移动轨迹，且每个移动轨迹之间不重合。从而当将与起始点重合的当前采集点作为终点位置，形成封闭轨迹图时，为了确保封闭轨迹图与采集区域对应，需要读封闭轨迹图的起始点和终点进行标识。具体地，可通过停留时间进行标识，当终端移动到起始点，在此起始点停留一段时间，相应的当终端的当前采集点再次到达起始点时，同样在此当前采集点停留一段时间，通过此停留时间确保移动终端在同一个采集区域移动。本实施例设置有预设时间，当终端移动到起始位置时，判断其在起始位置的停留时间是否大于预设时间，当停留时间大于预设时间，则将此起始位置作为采集区域的起始点。相应的在终端移动过程中对终端的当前采集点进行判断，确定其是否再次达到起始点，当当前采集点再次到达起始点时，进一步判断终端在当前采集点的停留时间是否大于预设时间，当大于预设时间时，则判定终端的当前采集点与起始点重合，此当前采集点为采集区域的终点。将此从起始点到终点形成的封闭轨迹图所对应的移动区域确定为采集区域中无线信号的有效采集位置，以和其他采集区域中无线信号的有效采集位置形成区别。
此外，本发明还提供一种自动规划无线信号采集位置的方法，参照图3，在本发明的自动规划无线信号采集位置的方法的第一实施例中，所述自动规划无线信号采集位置的方法包括：
步骤S60，接收终端基于采集区域的起始点实时采集、上传的移动过程中的移动参数和无线信号参数，并根据所述移动参数和无线信号参数绘制移动轨迹图；
步骤S70，检测移动轨迹图的当前绘制点是否与移动轨迹图的起始绘制点重合；
步骤S80，当移动轨迹图的当前绘制点与移动轨迹图的起始绘制点重合时，判定移动轨迹图形成封闭轨迹图，将所述封闭轨迹图对应的移动区域确定为无线信号的有效采集位置。
本发明的自动规划无线信号采集位置的方法适用于服务器，服务器接收终端实时采集并上传的移动参数和无线信号参数，并根据此移动参数和无线信号参数绘制移动轨迹图。移动终端在采集区域内移动，形成移动轨迹，移动轨迹上的不同点表征采集区域中不同位置的移动参数和无线信号参数。实时采集终端移动过程中不同点的移动参数和无线信号参数，并将此采集的移动参数和无线信号参数实时上传至服务器，服务器根据此移动参数和无线信号参数绘制表征采集区域的移动轨迹图。同时在绘制移动轨迹图的过程中，检测移动轨迹图的当前绘制点是否与移动轨迹图的起始绘制点重合，若当前绘制点与起始绘制点重合时，则说明移动轨迹图形成封闭轨迹图，终端移动轨迹为绕采集区域一圈的封闭轨迹，将此封闭轨迹图对应的终端移动区域确定为无线信号有效采集位置。通过服务器根据上传的移动参数和无线信号参数，绘制移动轨迹图，确定有效采集位置，无需在电子图片确定打点位置后由采集人员现场打点操作，节省人力成本，并通过服务器检测终端在采集区域移动轨迹的有效性，来确保采集点的有效性，使规划的有效采集位置更精确。
进一步地，在本发明自动规划无线信号采集位置的方法另一实施例中，所述移动参数包括移动速度和方向角，
所述根据所述移动参数和无线信号参数绘制移动轨迹图的步骤包括：
步骤S61，获取接收到当前移动参数和上一时刻移动参数的时间间隔，并根据所述时间间隔以及当前移动参数中的当前移动速度确定当前位移大小；
步骤S62，根据当前无线信号参数以及上一时刻移动参数，判断当前位移大小以及当前移动参数中的当前方向角是否有效；
步骤S63，若当前位移大小以及当前移动参数中的当前方向角有效，则根据当前位移大小以及当前方向角对移动轨迹图进行更新。
更进一步地，终端移动过程中的移动参数包括移动速度和方向角，移动速度表征终端移动的快慢，方向角为N-E方向角，其为在N-E坐标系中，以正北方向为0弧度，射线从沿顺时针方向转过的角度对360取模运算后的结果，逆时针方向为负值。N-E坐标系为在正北-正东方向建立的垂直坐标系中，N轴正方向为正北方向，E轴正方向为正东方向。在接收到终端实时上传的移动参数时，获取接收到当前移动参数的当前时间，同时获取在接收到当前移动参数之前的接收上一时刻终端上传的移动参数的上一时刻时间，确定当前时间与上一时刻时间的时间间隔。获取此接收到当前移动参数和上一时刻移动参数的时间间隔，并将当前移动参数中包括的当前移动速度作为此时间间隔内的平局移动速度，根据此时间间隔以及当前移动速度确定当前位移大小。可理解地，终端在移动过程中可能出现移动轨迹异常的情况，当移动轨迹异常时，确定的当前位移大小以及接收的当前方向角均无效，不能将根据其绘制移动轨迹图，从而需对当前位移大小以及当前方向角的有效性进行判断。具体地，获取上一时刻终端上传的上一时刻移动参数，根据此上一时刻移动参数以及当前无线信号参数，判断当前位移大小和当前方向角是否有效。当判断出当前位移大小和当前方向角有效时，则将当前位移大小和当前方向角绘制到移动轨迹图上，对移动轨迹图进行更新。其中根据当前无线信号参数以及上一时刻移动参数，判断当前位移大小以及当前移动参数中的当前方向角是否有效的步骤包括：
步骤S621，获取当前无线信号参数中MAC地址的RSSI当前时间序列规律，并将所述当前时间序列规律和上一时刻时间序列规律比对，获得比对结果；
步骤S622，根据所述比对结果、SSID以及上一时刻移动参数，判断当前位移大小以及当前移动参数中的当前方向角是否有效。
更进一步地，无线信号参数包括MAC地址、SSID和RSSI，MAC地址用于表示采集区域中发射无线信号装置的MAC地址，SSID用于表示采集区域中无线信号的名称，RSSI用于表征采集区域中发射无线信号装置所发射的无线信号强度，其强度大小与空间物理位置以及移动速度关联。终端在移动过程中，其空间物理位置和移动速度均随时间变化，使终端移动轨迹上的不同轨迹点具有不同的信号强度，其信号强度随着时间变化有对应的时间序列规律。在对当前位移大小和当前方向角的有效性判断时，获取当前无线信号参数中MAC地址的RSSI当前时间序列规律，MAC地址表征终端唯一性的物理地址，MAC地址的RSSI用于表示同一个终端的RSSI。将此当前时间序列规律和上一时刻的时间序列规律比对，获得比对结果。可理解地，对于同一终端以及同一采集区域，虽然终端在采集区域中移动，但是其移动的范围不会超出此采集区域，移动导致的信号强度相差不会太大。从而如果当前时间序列规律和上一时刻的时间序列规律相差很大，则说明终端的移动轨迹有误；或者两者相同，则说明终端没有移动，此采集的当前移动参数均无效。同样的终端在采集区域中移动，其移动轨迹中当前轨迹点的移动参数和上一时刻轨迹点的移动参数相差不大，当出现当前移动速度远远大于上一时刻移动速度的情况，则说明采集的当前移动参数异常；或者当前方向角和上一时刻方向角相反时，则说明终端向轨迹相反的方向移动，此采集的当前移动参数也异常，均为无效当前移动参数。此外不同的采集区域所具有的无线信号名称，即SSID不相同，从而当采集的无线信号参数中SSID一直相同，或者是变化频繁，则说明采集的无线信号参数有误，为无效当前移动参数。从而根据当前时间序列规律和上一时刻时间序列规律的比对结果、SSID以及上一时刻移动参数，判断当前位移大小以及当前方向角是否有效。
若当前位移大小和当前方向角均有效，将此当前位移大小和当前方向角绘制到移动轨迹图上。请参照图6，为一实施例中服务器根据当前位移大小和当前方向角确定的封闭轨迹图，每个网格的边长为单位1的正方形，采集区域包括1、2、3三个，圆点分别为三个采集区域的起始点，小箭头的方向为终端移动方向。设定N-E坐标系，终端从N-E坐标系的坐标圆点顺时针移动，按照预设采集时间上传的移动参数，在N-E坐标系得到的坐标点分别是(0，0)、(-1，1)、(-6，2)、(-7，4)、(-14，8)、(-7，4)、(-5，6)、(-4，7)、(-3，8)、(0，13)、(7，13)、(0，9)、(-3，8)、(-1，6)、(0，6)、(2，6)、(6，6)、(2，2)、(2，6)、(1，3)和(0，0)；其中采集区域1的位置坐标变化为(-7，4)、(-14，8)、(-7，4)；采集区域2的位置坐标变化为(-3，8)、(0，13)、(7，13)、(0，9)、(-3，8)；采集区域3的位置坐标变化为(2，6)、(6，6)、(2，2)、(2，6)。即移动终端到达采集区域1的起始点时，在此起始点停留大于预设时长的时间后从此起始点开始移动，移动到经过预设采集时间时，获取采集区域1的第一采集点，经过转化后得到第一坐标点（-7、4）以及对应第一方向角，将此第一坐标点和第一方向角绘制成移动轨迹图；终端继续移动，当再次移动到经过预设采集时间时获取采集区域1的第二个采集点，经过转化后得到第二坐标点（-14、8）以及对应的第二方向角，同样将此第二坐标点以及第二方向角绘制成移动轨迹图；此后每到一次预设采集时间就进行一次采集，并在采集的移动参数有效时，将移动参数绘制成移动轨迹图；直到终端的位置移动到与起始点重合，形成封闭轨迹图，将此封闭轨迹图对应的移动区域确定为无线信号的有效采集位置。
进一步地，在本发明自动规划无线信号采集位置的方法另一实施例中，所述所述判断当前位移大小以及当前移动参数中的当前方向角是否有效的步骤之后包括：
步骤S64，若当前位移大小以及当前移动参数中的当前方向角无效，则生成当前采集的移动参数以及无线信号参数无效的提示信息，并将所述提示信息下发到终端。
可理解地，当服务器判断出当前位移大小以及当前移动参数中的当前方向角无效时，生成当前采集的移动参数以及无线信号参数无效的提示信息，并将所述提示信息下发到终端。终端接收到此提示信息，更换移动轨迹，从更换后的新移动轨迹中采集移动参数和无线信号参数。此外当检测到终端的当前采集点与移动轨迹中的某一点重合，此点非起始点，即终端在采集区域中的移动轨迹出现交叉时，因交叉形成的封闭区域不能体现采集区域的范围，判定此采集的终端当前采集点的移动参数无效，也相应的生成无效的提示信息，以提示更换终端移动路线。通过此服务器的判断，对终端的移动轨迹进行约束，使绘制的移动轨迹图更为准确。
进一步地，请参照图4，在本发明自动规划无线信号采集位置的方法第一实施例的基础上，提出本发明自动规划无线信号采集位置的方法第二实施例，在第二实施例中，所述将所述封闭轨迹图对应的移动区域确定为无线信号的有效采集位置的步骤之后包括：
步骤S90，建立采集区域的无线信号参数与有效采集位置之间的对应关系；
步骤S100，当接收到对待定位对象的定位请求时，获取待定位对象所在环境的环境信号参数；
步骤S110，将所述环境信号参数与有效采集位置所对应的无线信号参数匹配，根据匹配结果进行待定位对象的定位。
更进一步地，因在规划无线信号的有效采集位置时，会将终端在采集区域中采集的无线信号参数上传，使有效采集位置有此采集区域的无线信号参数，即采集区域的无线信号参数中MAC地址、SSID以及RSSI相应的吸附归属到有效采集位置中，建立采集区域的无线信号参数与有效采集位置之间的对应关系。当接收到待定位对象的定位请求时，获取待定位对象所在环境的环境信号参数，环境信号参数即为待定位对象所在环境的WIFI信号的MAC地址、SSID和RSSI。将此环境信号参数与各个有效采集位置对应的无线信号参数匹配，当与某个有效采集位置对应的无线信号参数匹配时，则可确定待定位对象的位置为此匹配的有效采集位置，完成待定位对象的定位。为辅助理解以一具体实施例加以说明，请参照图8，某一商场内三个店铺的有效采集位置分别为A、B、C，其对应的MAC地址分别为a1、b1和c1，对应的SSID分别为a2、b2和c2，对应的RSSI分别在a3~a4、b3~b4以及c3~c4的区间内，且RSSI区间可能存在重叠的部分。当接收到待定位对象K的定位请求时，获取待定位对象所在环境的环境信号参数，如获取的环境信号参数表明：K所在环境的MAC地址为c1、SSID为c1，RSSI在c3~c4之间。将K所在环境的环境信号参数和三个店铺的有效采集位置对应的无线信号参数匹配，则可知其环境信号参数与有效采集位置C对应的无线信号参数匹配，根据此匹配结果判定待定位对象位于有效采集位置C所对应的店铺中，从而实现待定位对象的定位。
