本发明的技术方案具体如下：
一种多线圈阵列式无线供电系统接收端定位方法， 包括：

具体实施方式
为了更清楚的说明本发明的技术方案， 下面结合附图对本发明做详细的说 明。
参见图 1， 一种多线圈阵列式无线供电系统接收端定位方法， 包括：
51、 发射端检测定位单元的代表定位线圈， 找到有接收端的代表定位线 圈；
52、 从有接收端的代表定位线圈找到接收端对应的定位单元， 从该定位单 元的所有定位线圈中找出离接收端最近的定位线圈；
53、 从所述离接收端最近的定位线圈找到接收端对应的定位区域， 从该定 位区域的线圈中找出接收端所在位置处的线圈。
在歩骤 S1之前， 将发射端线圈阵列划分为若干个定位单元， 每个定位单元 包括若干个定位区域， 每个定位区域包括若干个线圈； 每个定位区域的若干个 线圈中， 其中一个为定位线圈， 其它为普通线圈； 从每个定位单元的所有定位 线圈中选出一个定位线圈作为代表定位线圈； 所述定位区域与所述定位线圈对 应， 所述定位单元与所述代表定位线圈对应。
其中， 从每个定位单元的所有定位线圈中选出一个定位线圈作为代表定位 线圈具体为： 选出位于定位单元中部的定位区域的定位线圈作为代表定位线 圈。
其中， 定位单元满足如下要求： 所有定位单元的组合能够覆盖整个发射端 线圈阵列； 定位单元互不重叠； 定位单元由连续的若干发射端线圈组成； 接收 端在定位单元的定位区域内， 与定位单元中的至少一个线圈形成谐振。
歩骤 S1 中所述发射端检测定位单元的代表定位线圈、 歩骤 S2中所述从该 定位单元的所有定位线圈中找出离接收端最近的定位线圈、 歩骤 S3中所述从该 定位区域的线圈中找出接收端所在位置处的线圈的方法有多种实现途径： 1、 直接启动发射端线圈向接收端传输电能， 通过检测发射端线圈电压或电流的变 化 来进行定位。 2、 在发射端增加某一感应器件， 通过该感应器件感应物理量 的变化来进行定位， 比如在发射端增加霍尔传感器， 当有电能接收物靠近该霍 尔传感器附近的线圈时， 该霍尔传感器感应到的磁场将发生变化， 所以通过霍 尔传感器磁场的变化可进行接收端的定位。
本发明通过将发射端线圈阵列划分为若干个定位单元， 每个定位单元包含 若干个定位区域， 为每个定位区域选定一个定位线圈， 为每个定位单元选定一 个代表定位线圈， 按"代表定位线圈 -定位单元-定位线圈-定位区域 -接收端所在 位置处的线圈"的定位次序， 定位出接收端的所在位置。 本发明通过一定的定 位次序， 可提高定位速度， 缩短定位时间， 并且减少能量损失， 降低电磁辐 射。
参见图 2， 一种多线圈阵列式无线供电系统接收端定位方法， 包括：
51、 发射端检测定位单元的代表定位线圈， 找到有接收端的代表定位线 圈；
52、 从有接收端的代表定位线圈找到接收端对应的定位单元， 从该定位单 元的所有定位线圈中找出离接收端最近的定位线圈；
53、 从所述离接收端最近的定位线圈找到接收端对应的定位区域， 从该定 位区域的线圈中找出接收端所在位置处的线圈。
在歩骤 S1之前， 将发射端线圈阵列划分为若干个定位单元， 每个定位单元 包括若干个定位区域， 每个定位区域包括若干个线圈； 每个定位区域的若干个 线圈中， 其中一个为定位线圈， 其它为普通线圈； 从每个定位单元的所有定位 线圈中选出一个定位线圈作为代表定位线圈； 所述定位区域与所述定位线圈对 应， 所述定位单元与所述代表定位线圈对应。
其中， 从每个定位单元的所有定位线圈中选出一个定位线圈作为代表定位 线圈具体为： 选出位于定位单元中部的定位区域的定位线圈作为代表定位线 圈。
其中， 定位单元满足如下要求： 所有定位单元的组合能够覆盖整个发射端 线圈阵列； 定位单元互不重叠； 定位单元由连续的若干发射端线圈组成； 接收 端在定位单元的定位区域内， 与定位单元中的至少一个线圈形成谐振。
S23、 发射端识别所述接收端是否为期望接收端， 如果是， 执行歩骤
S231 ; 否则， 执行歩骤 S230。
歩骤 S23中， 所述发射端识别所述接收端是否为期望接收端的方法包括： 发射端启动接收端所在位置处的发射端线圈， 向接收端传输能量； 期望接收端收到发射端传输的能量后启动，在一定时间 tir^内向发射端发送 能唯一标示其身份的 RXID信号， 并且以一定的时间间隔 ½ 向发射端发送
RXID信号； RXID信号的持续时间为 参见图 3(a)， 图 3(a)为期望接收端线 圈状态的示意图。
发射端在一定的时间 tir^ 内， 若接收到 RXID信号， 则将该接收端识别为 期望接收端； 否则， 将该接收端标记为异物。 参见图 30)：)， 图 30)：)为期望接收端 所在位置处的发射端线圈的状态示意图。 为了简化图 3(b), 将图 3(b)中的两个信 号合并到一个图中， 得到图 3(c), 参见图 3(c), 可以清楚的看到， 当期望接收端 所在位置处的发射端线圈通电启动后， 所述期望接收端所在位置处的发射端线 圈的状态。
发射端依次启动需要检测的发射端线圈， 等待一定的时间 tir^ ， 若在此时 间内收到 RXID信号， 则将该线圈位置处的接收端识别为期望接收端； 若在时间 tir^sw内未收到 RXID信号， 则将该线圈位置处的接收端识别为异物， 并将该线 圈的状态标记为异物。 检测完第一个线圈， 检测下一个需要检测的线圈， 以此 类推， 直到检测完所有需要检测的发射端线圈， 识别工作完成。 参见图 3(d) , 图 3(d)为发射端识别接收端的时序图。
5230、 不启动所述接收端所在位置处的发射端线圈， 并将所述接收端所在 位置处的发射端线圈的状态标记为异物；
5231、 启动所述接收端所在位置处的发射端线圈， 对接收端进行供电； S24、 判断发射端是否处于供电状态， 如果是， 则执行歩骤 S241 ; 否则， 执 行歩骤 S240;
5240、 直接启动所述接收端所在位置处的发射端线圈；
歩骤 S240中， 当发射端不处于供电状态时， 即要供电的接收端为发射端系 统的第一个接收端， 则直接启动所述接收端所在位置处的发射端线圈， 参见图 3(e), 图 3(e)为给发射端系统的第一个接收端供电时的发射端线圈的时序图。
5241、 发射端采用通讯信道的分时共用法对接收端进行供电。
歩骤 S241中， 当发射端已处于供电状态时， 即要供电的接收端不是发射端 系统的第一个接收端， 发射端系统要为新增的接收端供电时， 此时发射端系统 采用通讯信道的分时共用法为原来的接收端和新增的接收端供电。 具体为： 1、 新增接收端的信号的接收时间处于通讯信道的空闲区间； 2、 新增接收端的信号 与距离最近的其他接收端的信号之间的时间间隔 （t^M^^ ) 大于"近邻 Rx最小 时间间隔"（t近邻最小时间间隔）， 小于"近邻 Rx最大时间间隔"（t近邻最大时间 间隔）。 参见图 3(f), 图 3(f)为给发射端系统的第二个接收端供电时的发射端线圈 的时序图。 参见图 3(g), 图 3(g)为给发射端系统的第 N个接收端供电时的发射端 线圈的时序图。
本发明通过将发射端线圈阵列划分为若干个定位单元， 每个定位单元包含 若干个定位区域， 为每个定位区域选定一个定位线圈， 为每个定位单元选定一 个代表定位线圈， 按"代表定位线圈 -定位单元-定位线圈-定位区域 -接收端所在 位置处的线圈"的定位次序， 定位出接收端的所在位置。 本发明通过一定的定 位次序， 可提高定位速度， 缩短定位时间， 并且减少能量损失， 降低电磁辐 射。
参见图 4， 一种多线圈阵列式无线供电系统接收端定位方法中对接收端的 识别还包括： 发射端已处于供电状态时， 有新增接收端， 此时发射端对该新增 接收端的识别。 图 4为识别新增接收端时的发射端线圈的状态示意图。 发射端 已处于供电状态时， 有新增接收端， 此时发射端系统对该新增接收端的识别采 用通讯信道的分时共用法， 若识别为期望接收端， 则执行歩骤 S241 ; 否则， 执 行歩骤 S230。
一种多线圈阵列式无线供电系统接收端定位方法中对接收端的识别还包 括：
1、 当期望接收端发生异常时， 发射端识别到该期望接收端异常。 所述发 射端识别到期望接收端异常的方法具体为： 如果发射端经过一定的时间周期 (N 最大的 RXID超时周期 )未收到 RXID信号， 则发射端视为该期望接收端发生异常， 停止所 有该期望接收端对应的发射端线圈， 清除该期望接收端对应的所有发射端线圈 的标记状态， 所述一定的时间周期 (N最大的 RXID超时周期 )为程序设置的阈值 。
2、 当期望接收端被移走时， 发射端识别到该期望接收端被移走， 此时发 射端停止所有该期望接收端对应的发射端线圈， 清除该期望接收端对应的所有 发射端线圈的标记状态。 3、 当异物被移走时， 发射端识别到异物被移走， 发射端清除该异物对应 的发射端线圈的标记状态。
