本发明还提供一种多天线的无线远程电梯召唤的操控***的控制方法，按 如下步骤进行：  The invention also provides a control method for a multi-antenna wireless remote elevator calling control system, which is carried out as follows:
a、 基站控制基站第一信号发射天线和基站第二信号发射天线向周围空间 周期性地辐射， 形成电磁场；  a. The base station controls the first signal transmitting antenna of the base station and the second signal transmitting antenna of the base station to periodically radiate to the surrounding space to form an electromagnetic field;
b、 基站捕获到有效场强范围内有目标卡进入时， 唤醒目标卡；  b. When the base station captures the target card in the range of the effective field strength, the target card is awakened;
c、 基站第一信号发射天线连续发送第一时间段的信号， 然后停止； 目标 卡获得基于基站第一信号发射天线的场强数值， 并回传给基站；基站根据所述 场强数值获得目标卡到基站第一信号发射天线的第一距离；  c. The first signal transmitting antenna of the base station continuously transmits the signal of the first time period, and then stops; the target card obtains the field strength value of the transmitting antenna based on the first signal of the base station, and returns the signal to the base station; the base station obtains the target according to the field strength value. The first distance of the card to the first signal transmitting antenna of the base station;
当基站得出第一距离后，基站第二信号发射天线连续发送第一时间段的信 号， 然后停止； 目标卡传回基于基站第二信号发射天线的场强数值， 得到该目 标卡到基站第二信号发射天线的第二距离； 重复上述步骤，获得目标卡到基站第一信号发射天线的第三距离和目标卡 到基站第二信号发射天线的第四距离； After the base station obtains the first distance, the second signal transmitting antenna of the base station continuously transmits the signal of the first time period, and then stops; the target card returns the field strength value based on the second signal transmitting antenna of the base station, and obtains the target card to the base station. a second distance of the two signal transmitting antennas; Repeating the above steps, obtaining a third distance of the target card to the first signal transmitting antenna of the base station and a fourth distance of the target card to the second signal transmitting antenna of the base station;
d、 基站根据得到的以上四个距离的状态组合获得目标卡的运动轨迹， 若 判断出该目标卡的运动轨迹属于有效轨迹， 则判定为该目标卡要进入电梯； e、基站根据接收到的目标卡数据，得到该目标卡的 ID号并确定楼层响应 权限；  d. The base station obtains the motion trajectory of the target card according to the obtained state combination of the above four distances, and if it is determined that the motion trajectory of the target card belongs to the effective trajectory, it is determined that the target card is to enter the elevator; e, the base station according to the received Target card data, obtaining the ID number of the target card and determining the floor response authority;
f、 基站将电梯请求信号发给电梯主控板， 对电梯实施相应楼层的控制， 同时显示电梯运行 ^大态。  f. The base station sends the elevator request signal to the elevator main control board, and controls the corresponding floor of the elevator, and simultaneously displays the elevator operation.
优选地， 当基站根据得到的四个距离的状态组合， 判断出该目标卡的运 动轨迹属于无效轨迹时， 则判定为该目标卡不进入电梯。 本发明多天线的无线远程电梯召唤的操控***具有以下优点：  Preferably, when the base station determines that the motion track of the target card belongs to the invalid track according to the obtained state of the four distances, it is determined that the target card does not enter the elevator. The multi-antenna wireless remote elevator summoning control system of the invention has the following advantages:
本发明将原本需要乘客参与的主动式电梯召唤操控方式，将其改为基站自 动识别并响应的操控方式， 即乘客无需用手去触碰按键或刷卡， 只要在离电梯 一定距离的范围内， 乘客操作携带的目标卡， 电梯便自动响应召唤动作； 当客 户进入电梯轿厢后，还可自动相应目标楼层的操作， 开辟了无线遥控电梯的新 领域。  The invention adopts the active elevator call control mode which originally requires the passenger to participate, and changes it to the control mode in which the base station automatically recognizes and responds, that is, the passenger does not need to touch the button or swipe the card by hand, as long as it is within a certain distance from the elevator. When the passenger operates the target card, the elevator automatically responds to the summoning action; when the customer enters the elevator car, the operation of the corresponding target floor can also be automatically opened, opening up a new field of the wireless remote control elevator.
在无线远程电梯召唤的操控***的技术方案中存在一个难点，即如何处理 持卡人携带目标卡走过或路过电梯但无乘电梯的需求，基站却错将其认为需要 乘坐电梯而召唤电梯，从而造成了电梯误操作。本发明采用安装多天线的基站 的捕获方式来解决了此技术问题， 采用本发明的技术方案，如果目标卡处于移 动状态，基站可以获得该目标卡的运动规律及轨迹，基站越多捕获目标卡运动 轨迹就更加精确地判断该目标卡是否具有乘梯的意向，这样就可以避免目标卡 仅仅靠近基站而无乘梯意见却引起召唤电梯的误操作的弊端。 附图说明  In the technical solution of the wireless remote elevator call control system, there is a difficulty in how to deal with the cardholder carrying the target card to pass or pass the elevator but no need to take the elevator, but the base station mistakenly thinks that it needs to take the elevator and call the elevator. This caused the elevator to malfunction. The present invention solves the technical problem by adopting a capture mode of a base station with multiple antennas. With the technical solution of the present invention, if the target card is in a mobile state, the base station can obtain the motion law and trajectory of the target card, and the more the base station captures the target card. The motion trajectory makes it more accurate to judge whether the target card has the intention of riding the ladder, so that the target card can be prevented from being close to the base station without the riding advice but causing the erroneous operation of the calling elevator.

The elevator main control board is configured to perform basic command control and status display on the operation of the elevator after receiving the request signal sent by the base station.
通过基站与目标卡进行数据交换，基站可获得进入场强范围的目标卡 ID、 电池电量信息、 距离信息（可从电场强度获得）以及其他信息； 基站在获得这 些信息后， 可进行一系列的电梯操作， 比如厅外召唤、 相应授权楼层的相应等 等。 下面结合附图介绍本发明提供的多天线的无线远程电梯召唤的控制方法， 具体步骤如下：  Through the data exchange between the base station and the target card, the base station can obtain the target card ID, the battery power information, the distance information (obtainable from the electric field strength) and other information of the field strength range; after obtaining the information, the base station can perform a series of Elevator operation, such as calling outside the hall, corresponding to the authorized floor, etc. The control method for multi-antenna wireless remote elevator calling provided by the present invention will be described below with reference to the accompanying drawings. The specific steps are as follows:
a、 基站主控模块 103控制第一信号发射驱动模块 A和第二信号发射驱动 模块 B分别通过基站第一信号发射天线 A和基站第二信号发射天线 B向天线 周围的空间周期性的辐射电磁场。  a base station main control module 103 controls the first signal transmission driving module A and the second signal transmission driving module B to periodically radiate electromagnetic fields to the space around the antenna through the base station first signal transmitting antenna A and the base station second signal transmitting antenna B, respectively. .
b、 基站捕获到有效场强范围内有目标卡进入时：  b. When the base station captures the target field within the effective field strength range:
基站第一信号发射天线 A连续发送第一时间段 T1的信号， 然后停止； 此 时， 目标卡会获得基于基站第一信号发射天线 A的场强数值， 并回传给基站； 基站可获得目标卡到基站第一信号发射天线 A的第一距离 （记为： 距离 Al )。  The first signal transmitting antenna A of the base station continuously transmits the signal of the first time period T1, and then stops; at this time, the target card obtains the field strength value of the transmitting antenna A based on the first signal of the base station, and returns the signal to the base station; The first distance (indicated as: distance Al) that is stuck to the first signal transmitting antenna A of the base station.
当基站得出第一距离 A1后，基站第二信号发射天线 B连续发送第一时间 段 T1的信号， 然后停止； 此时， 该目标卡会传回基于基站第二信号发射天线 B 的场强数值， 同样可得到该目标卡到基站第二信号发射天线 B 的第二距离 (记为: 距离 B1 )。  After the base station obtains the first distance A1, the second signal transmitting antenna B of the base station continuously transmits the signal of the first time period T1, and then stops; at this time, the target card returns the field strength of the transmitting antenna B based on the second signal of the base station. The second distance of the target card to the base station second signal transmitting antenna B (denoted as: distance B1) is also obtained.
此后重复上述步骤， 基站第一信号发射天线 A继续发送信号， 再次获得 目标卡到基站第一信号发射天线 A的第三距离 （记为： 距离 A2 ), 同理可再 次得到目标卡到基站第二信号发射天线 B的第四距离 （记为： 距离 B2 )。  After repeating the above steps, the first signal transmitting antenna A of the base station continues to transmit the signal, and obtains the third distance of the target card to the first signal transmitting antenna A of the base station (recorded as: distance A2), and the target card can be obtained again to the base station. The fourth distance of the two signal transmitting antenna B (denoted as: distance B2).
通过基站第一信号发射天线 A和基站第二信号发射天线 B的安装位置以 及第一距离 Al、 第二距离 Bl、 第三距离 A2和第四距离 B2的状态组合， 可 以判断目标卡的运动轨迹。 The combination of the installation position of the first signal transmitting antenna A and the second signal transmitting antenna B of the base station and the states of the first distance A1, the second distance B1, the third distance A2, and the fourth distance B2 may be To determine the motion trajectory of the target card.
c、如此基站第一信号发射天线 A和基站第二信号发射天线 B轮流发送信 号， 则可不断的得到这 4个距离数值。 如果目标卡处于移动状态， 可以通过此 方法获得该目标卡的运动规律及轨迹，基站越多捕获目标卡运动轨迹判别就越 精确。  c. The base station first signal transmitting antenna A and the base station second signal transmitting antenna B transmit signals in turn, and the four distance values can be continuously obtained. If the target card is in a moving state, the motion law and trajectory of the target card can be obtained by this method, and the more the base station captures the target card motion trajectory, the more accurate it is.
目标卡离基站越近， 接收到的场强越强， 转换后的场强数值越大； 基站将 该目标卡的运动规律与程序设定好的运动规律进行比对，从而通过电梯通讯模 块进行相应的电梯控制，这样就可避免目标卡仅仅是靠近基站就引起误操作的 弊端。  The closer the target card is to the base station, the stronger the received field strength is, and the larger the field strength value after conversion is. The base station compares the motion law of the target card with the programmed motion law, thereby performing the elevator communication module. Corresponding elevator control, so as to avoid the disadvantage that the target card is only caused to be close to the base station.
d、 基站最终确认所有目标卡身份和位置， 发送信号给电梯主控板， 电梯 主控板对电梯进行控制和状态显示。  d. The base station finally confirms the identity and location of all the target cards, sends a signal to the elevator main control board, and the elevator main control board controls and displays the status of the elevator.
若目标卡如果不在基站的信号发射天线所辐射的电磁场有效范围内，则处 于休眠状态， 以节省电量。  If the target card is not within the effective range of the electromagnetic field radiated by the signal transmitting antenna of the base station, it is in a sleep state to save power.
若进入基站的信号发射天线所辐射的电磁场有效范围内， 则被激活， 进行 上述各步骤。  If it enters the effective range of the electromagnetic field radiated by the signal transmitting antenna of the base station, it is activated to perform the above steps.
若目标卡离开基站的信号发射天线辐射的电磁场范围，则再次进入休眠状 态。  If the target card leaves the electromagnetic field range radiated by the signal transmitting antenna of the base station, it enters the sleep state again.
本发明将原本需要乘客参与的主动式电梯召唤操控方式，将其改为基站自 动识别并响应的操控方式， 即乘客无需用手去触碰按键或刷卡， 只要在离电梯 一定距离的范围内， 乘客操作携带的目标卡， 电梯便自动响应召唤动作； 当客 户进入电梯轿厢后，还可自动相应目标楼层的操作， 开辟了无线遥控电梯的新 领域。  The invention adopts the active elevator call control mode which originally requires the passenger to participate, and changes it to the control mode in which the base station automatically recognizes and responds, that is, the passenger does not need to touch the button or swipe the card by hand, as long as it is within a certain distance from the elevator. When the passenger operates the target card, the elevator automatically responds to the summoning action; when the customer enters the elevator car, the operation of the corresponding target floor can also be automatically opened, opening up a new field of the wireless remote control elevator.
在无线远程电梯召唤的操控***的技术方案中存在一个难点，即如何处理 持卡人携带目标卡走过或路过电梯但无乘电梯的需求，基站却错将其认为需要 乘坐电梯而召唤电梯，从而造成了电梯误操作。本发明采用安装多天线的基站 的捕获方式来解决了此技术问题， 采用本发明的技术方案，如果目标卡处于移 动状态，基站可以获得该目标卡的运动规律及轨迹，基站越多捕获目标卡运动 轨迹就更加精确地判断该目标卡是否具有乘梯的意向，这样就可以避免目标卡 仅仅靠近基站而无乘梯意见却引起召唤电梯的误操作的弊端。 以上所述，仅是本发明的较佳实施例而已， 并非对本发明作任何形式上的 限制。 虽然本发明已以较佳实施例揭露如上， 然而并非用以限定本发明。 任何 熟悉本领域的技术人员， 在不脱离本发明技术方案范围情况下， 都可利用上述 揭示的方法和技术内容对本发明技术方案做出许多可能的变动和修饰，或修改 为等同变化的等效实施例。 因此， 凡是未脱离本发明技术方案的内容， 依据本 发明的技术实质对以上实施例所做的任何筒单修改、等同变化及修饰， 均仍属 于本发明技术方案保护的范围内。 In the technical solution of the wireless remote elevator call control system, there is a difficulty in how to deal with the cardholder carrying the target card to pass or pass the elevator but no need to take the elevator, but the base station mistakenly thinks that it needs to take the elevator and call the elevator. This caused the elevator to malfunction. The present invention solves the technical problem by adopting a capture mode of a base station with multiple antennas. With the technical solution of the present invention, if the target card is in a mobile state, the base station can obtain the motion law and trajectory of the target card, and the more the base station captures the target card. The motion trajectory makes it more accurate to judge whether the target card has the intention of riding the ladder, so that the target card can be prevented from being close to the base station without the riding advice but causing the erroneous operation of the calling elevator. The above description is only a preferred embodiment of the invention and is not intended to limit the invention in any way. Although the present invention has been disclosed above in the preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention by using the methods and technical contents disclosed above, or modify the equivalents of equivalent changes without departing from the scope of the technical solutions of the present invention. Example. Therefore, any modification, equivalent changes, and modifications made to the above embodiments in accordance with the technical spirit of the present invention are still within the scope of protection of the technical solutions of the present invention.
