Description
无线供电系统及其控制方法 技术领域 Wireless power supply system and control method thereof
本发明是有关于一种无线供电系统, 且特别是有关于一种无线供电系统 及其控制方法。 The present invention relates to a wireless power supply system, and more particularly to a wireless power supply system and control method therefor.
背景技术 Background technique
在电子产品的应用领域当中， 例如电视、 空调等家电的使用越来越普遍， 也使现在家庭中电子产品越来越多， 从而会造成房间布线繁乱、 家电位置固 定化、 居室墙面被插座破坏等问题， 影响居室美化度。 鉴于这个原因， 市场 上目前出现了具有复制和取代功能的设备， 发挥了一定积极作用。 也即， 通 过无线电力传输取代有线电力传输， 这对于用户来说还将大量节省布线所用 的铜、 塑料等材料， 节约了资源， 减少了污染， 并根据需要随处移动， 同时 还避免了插拔电源带来的安全隐患。 In the field of application of electronic products, the use of home appliances such as televisions and air conditioners is becoming more and more common, and more and more electronic products are now available in the home, which will result in messy room wiring, fixed home appliances, and wall sockets. Destruction and other issues affect the degree of room beautification. For this reason, devices with replication and replacement functions have emerged in the market and have played a positive role. That is to say, wireless power transmission replaces wired power transmission, which will save a lot of materials such as copper and plastic for wiring, save resources, reduce pollution, and move anywhere according to needs, while avoiding plugging and unplugging. The security risks caused by the power supply.
一般地， 无线电力传输只是利用无线电力发射端作为原边进行简单的电 力发射， 无线电力接收端作为副边进行接收， 整个系统是开环的。 原边上电 后一直保持固定的发射模式， 不管副边负载是否改变， 譬如当用户操作遥控 器， 电视机进入待机后， 副边的负载非常低， 而此时原边依然釆用既定的模 式发射， 首先会造成功耗的浪费， 其次容易造成原、 副边线圈的自激， 线圈 热量急剧上升， 势必损坏原、 副边器件及线圈。 Generally, wireless power transmission uses only a wireless power transmitting end as a primary side for simple power transmission, and a wireless power receiving end as a secondary side for receiving, and the entire system is open loop. The primary side maintains a fixed transmission mode after power-on, regardless of whether the secondary load changes, for example, when the user operates the remote control, after the TV enters standby, the load on the secondary side is very low, and the primary side still uses the established mode. The first transmission will cause waste of power consumption. Secondly, it will easily cause self-excitation of the primary and secondary coils. The heat of the coil will rise sharply, which will damage the original and secondary components and coils.

The wireless power transmitting end 23 and the wireless power receiving end 13 respectively include a transmitting coil and a receiving coil, and a resonant or electromagnetic induction coupling between the transmitting coil of the wireless power transmitting end 23 and the receiving coil of the wireless power receiving end 13 enables wireless The power transmitting end 23 wirelessly transmits the power input from the commercial power to the wireless power receiving terminal 13, and further converts the power received by the wireless power receiving terminal 13 into a DC voltage suitable for the television through the AC-DC power source 14 to be the television set. Provide power. In this embodiment, the resonant or electromagnetic inductive coupling principle between the wireless power transmitting end 23 and the wireless power receiving end 13 is a common technical means in the existing wireless power transmission, and details are not described herein again. In the present embodiment, in the case where the transmitting coil of the wireless power transmitting terminal 23 and the receiving coil of the wireless power receiving terminal 13 are coupled, the wireless power transmitting terminal 23 can be at a high power. The coil transmission mode and the low power coil transmission mode work, wherein the high power coil transmission mode is suitable for the power on state of the television, and the low power coil transmission mode is suitable for the standby state of the television.
具体地， 如果在用户操作遥控器或是按键控制电视机（图未示）开机时， 电视机主板 15传送一个开机命令至第一控制模块 12, 第一控制模块 12通过 无线通讯模块 11将该接收到的开机命令对应的指令通过无线电力发射装置 2 的无线通讯模块 21传送至第二控制模块 22。 根据该开机命令对应的指令， 第二控制模块 22控制无线电力发射端 23进入大功率线圈发射模式。 无线电 力发射端 23在大功率线圈发射模式下， 向无线电力接收端 13传输的电力可 以满足电视机开机状态下的功耗需求。 Specifically, if the user operates the remote controller or the button control television (not shown) is turned on, the television main board 15 transmits a power-on command to the first control module 12, and the first control module 12 passes the wireless communication module 11 The command corresponding to the received power-on command is transmitted to the second control module 22 through the wireless communication module 21 of the wireless power transmitting device 2. According to the instruction corresponding to the power-on command, the second control module 22 controls the wireless power transmitting terminal 23 to enter the high-power coil transmitting mode. In the high power coil transmitting mode, the radio power transmitting end 23 transmits power to the wireless power receiving end 13 to meet the power consumption requirement of the television when the television is turned on.
如果用户操作遥控器或按键控制电视机进入待机状态时， 电视机主板 15 传送一个待机命令至第一控制模块 12, 第一控制模块 12通过无线通讯模块 11将该接收到的待机命令对应的指令通过无线电力发射装置 2的无线通讯模 块 21传送至第二控制模块 22。 根据该待机命令对应的指令， 第二控制模块 22控制无线电力发射端 23进入小功率线圈发射模式。 此时， 无线电力发射 端 23关闭大功率线圈发射， 切换为小功率线圈发射模式， 或通过改变发射频 率， 釆用突波式发射来降低功耗。 If the user operates the remote controller or presses the button to control the television to enter the standby state, the television main board 15 transmits a standby command to the first control module 12, and the first control module 12 receives the command corresponding to the received standby command through the wireless communication module 11. It is transmitted to the second control module 22 through the wireless communication module 21 of the wireless power transmitting device 2. Based on the instruction corresponding to the standby command, the second control module 22 controls the wireless power transmitting terminal 23 to enter the low power coil transmitting mode. At this time, the wireless power transmitter 23 turns off the high power coil transmission, switches to the low power coil transmission mode, or changes the transmission frequency, and uses the surge transmission to reduce the power consumption.
由于待机状态下， 无线电力接收端 13的负载非常低， 因此， 无线电力发 射端 23在小功率线圈发射模式下， 向无线电力接收端 13传输的电力可以满 足电视机待机状态下的功耗需求即可， 从而避免功率的浪费， 同时还避免无 线电力发射端 23的发射线圈和无线电力接收端 13的接收线圈发生自激， 导 致线圈热量急剧上升而损坏无线供电系统 100内的全部或部分元件， 从而可 使无线供电系统 100工作稳定， 寿命延长。 Since the load of the wireless power receiving end 13 is very low in the standby state, the power transmitted by the wireless power transmitting end 23 to the wireless power receiving end 13 in the low power coil transmitting mode can satisfy the power consumption requirement of the television standby state. That is, to avoid waste of power, and at the same time, avoiding the self-excitation of the transmitting coil of the wireless power transmitting end 23 and the receiving coil of the wireless power receiving end 13, causing the coil heat to rise sharply and damage all or part of the components in the wireless power feeding system 100. Therefore, the wireless power supply system 100 can be stably operated and has a long life.
无线通讯模块 11和 21之间以红外通讯、 蓝牙通讯等短距离无线通讯形 式进行通讯， 也可使用射频通讯技术。 也即， 无线通讯模块 11和 21可以分 别是红外通讯模块、 蓝牙通讯模块或射频通讯模块等无线通讯模块。 本发明 不受上述通讯方式限制， 只要可实现在无线通讯模块 11和 21之间进行无线 信号收发的其他通讯技术同样适应于本发明。 The wireless communication module 11 and 21 communicate in the form of short-range wireless communication such as infrared communication or Bluetooth communication, and can also use radio frequency communication technology. That is, the wireless communication modules 11 and 21 can be wireless communication modules such as an infrared communication module, a Bluetooth communication module, or a radio frequency communication module. The present invention is not limited by the above communication method, and other communication techniques capable of transmitting and receiving wireless signals between the wireless communication modules 11 and 21 are also suitable for the present invention.
此外， 本实施例中的电视机主板 15只是针对电视机而言， 如果用于其他 电子装置， 该电视机主板 15可以是其他电子装置的主板， 如电脑主板等， 也
可以是用于收发电子装置开机命令及待机命令的状态控制模块。 In addition, the TV main board 15 in this embodiment is only for a television set. If it is used for other electronic devices, the TV main board 15 may be a main board of other electronic devices, such as a computer motherboard, etc. It may be a state control module for transmitting and receiving electronic device boot commands and standby commands.
此外， 本发明还提供一种用于上述无线供电系统的控制方法， 该无线供 电系统的无线电力发射端可切换地工作在大功率线圈发射模式和小功率线圈 发射模式。 此方法包括如下步骤： 电视机主板 15接收一个开机命令； 将这一 开机命令传送至无线电力接收装置 1的第一控制模块 12; 将开机命令对应的 指令传送至无线电力发射装置的第二控制模块 22; 根据该开机命令对应的指 令， 第二控制模块 22控制无线电力发射端 23进入大功率线圈发射模式； 电 视机主板 15接收一个待机命令； 将这一待机命令传送至无线电力接收装置 1 的第一控制模块 12; 将待机命令对应的指令传送至无线电力发射装置的第二 控制模块 22; 根据该待机命令对应的指令， 第二控制模块 22控制无线电力 发射端 23进入小功率线圈发射模式。 此时， 无线电力发射端 23关闭大功率 线圈发射模式， 切换为小功率线圈发射模式。 上述是先开机再待机的模式切 换过程， 类似地， 如果将电视机从待机模式切换至开机模式， 上述的电视机 主板 15接收待机命令， 使无线电力发射端 23进入小功率线圈发射模式。 当 电视机主板 15接收开机命令时， 第一控制模块 12将开机命令对应的指令传 送至第二控制模块 22, 第二控制模块 22控制无线电力发射端 23从小功率线 圈发射模式切换进入大功率线圈发射模式。 Furthermore, the present invention also provides a control method for the above wireless power supply system, the wireless power transmitting end of the wireless power supply system being switchably operable in a high power coil transmitting mode and a low power coil transmitting mode. The method includes the following steps: the TV main board 15 receives a power-on command; transmits the power-on command to the first control module 12 of the wireless power receiving device 1; and transmits the command corresponding to the power-on command to the second control of the wireless power transmitting device The module 22 controls the wireless power transmitting terminal 23 to enter the high power coil transmitting mode according to the instruction corresponding to the powering command; the television main board 15 receives a standby command; and transmits the standby command to the wireless power receiving device 1 The first control module 12 transmits the instruction corresponding to the standby command to the second control module 22 of the wireless power transmitting device; according to the instruction corresponding to the standby command, the second control module 22 controls the wireless power transmitting terminal 23 to enter the small power coil to transmit mode. At this time, the wireless power transmitting terminal 23 turns off the high power coil transmitting mode and switches to the low power coil transmitting mode. The above is a mode switching process of turning on and then standby. Similarly, if the television is switched from the standby mode to the power-on mode, the above-described television main board 15 receives the standby command, causing the wireless power transmitting terminal 23 to enter the low power coil transmitting mode. When the TV main board 15 receives the power-on command, the first control module 12 transmits an instruction corresponding to the power-on command to the second control module 22, and the second control module 22 controls the wireless power transmitting terminal 23 to switch from the small-power coil transmission mode to the high-power coil.
