Description
Translated fromChinese技术领域technical field
本发明涉及磁共振无线充电技术领域，尤其涉及一种多设备无线充电方法及系统。The invention relates to the technical field of magnetic resonance wireless charging, and in particular, to a multi-device wireless charging method and system.
背景技术Background technique
目前，无线充电技术主要有电磁感应式、磁共振式、电场耦合式、无线电波式四种基本方式。当前最成熟、最普遍的是电磁感应式，其技术是应用电磁感应原理，交变电流流过发射线圈产生变化的磁场，发射线圈在变化的磁场下产生电流，从而为接收设备充电。磁共振式技术也是应用电磁感应原理，发射与接收频率相同达到共振效果，以加强传输效率。电场耦合技术原理是通过电场将发射的电能转移到接收，利用通过垂直方向耦合的两组非对称偶极子而产生的感应电场来传输电能。无线电波技术原理是将电磁波转换为电流，通过电路传输电流，但具有传输距离小、转换效率低、辐射大等缺点。At present, there are four basic methods of wireless charging technology: electromagnetic induction, magnetic resonance, electric field coupling, and radio wave. At present, the most mature and common is the electromagnetic induction type. Its technology is to apply the principle of electromagnetic induction. An alternating current flows through the transmitting coil to generate a changing magnetic field, and the transmitting coil generates a current under the changing magnetic field, thereby charging the receiving device. Magnetic resonance technology also applies the principle of electromagnetic induction, and the transmission and reception frequencies are the same to achieve resonance effect to enhance transmission efficiency. The principle of electric field coupling technology is to transfer the transmitted electric energy to the receiver through the electric field, and use the induced electric field generated by two sets of asymmetric dipoles coupled in the vertical direction to transmit the electric energy. The principle of radio wave technology is to convert electromagnetic waves into electric current and transmit electric current through the circuit, but it has the disadvantages of small transmission distance, low conversion efficiency and large radiation.
现有技术：三星立式无线充电板、Apple watch无线充电器等各式各样充电板的原理基本上是电磁感应式充电，充电设备与充电板需要贴合，随着无线充电技术的不断发展与演进，各大公司的研究方向已转为充电板可以为任意方向、适当距离内为多台移动设备充电，现有的贴合式无线充电产品并不能满足人们的需求。Existing technology: The principle of various charging boards such as Samsung vertical wireless charging board and Apple watch wireless charger is basically electromagnetic induction charging. The charging device and the charging board need to be fitted together. With the continuous development of wireless charging technology With the evolution, the research direction of major companies has shifted to the charging board that can charge multiple mobile devices in any direction and within an appropriate distance. The existing fit wireless charging products cannot meet people's needs.
而磁共振无线充电技术是无线充电的主流技术之一，具有传输距离长和效率高等优点。伴随着WPC1.2规范发布后，当前的市场开始由磁感应技术向磁共振无线充电技术转变，其主要针对移动智能设备、穿戴式设备、低功率小型设备等进行充电。磁共振无线充电技术产品可以制作成一个充电板(含有单个或多个线圈发射)，可同时对多个接收设备充电，成为无线充电市场未来的发展方向。充电接收设备的充电效率与离充电板位置息息相关，充电板是由多个线圈构成的发射，每个线圈与在有效充电区内的接收设备都有不同的磁感应程度。为了能更好的管理多设备无线充电，需要提出一个多设备无线充电方案，使无线充电系统更智能、高效和安全。The magnetic resonance wireless charging technology is one of the mainstream technologies of wireless charging, which has the advantages of long transmission distance and high efficiency. With the release of the WPC1.2 specification, the current market has begun to transform from magnetic induction technology to magnetic resonance wireless charging technology, which is mainly aimed at charging mobile smart devices, wearable devices, and low-power small devices. Magnetic resonance wireless charging technology products can be made into a charging board (with single or multiple coil transmitters), which can charge multiple receiving devices at the same time, becoming the future development direction of the wireless charging market. The charging efficiency of the charging receiving device is closely related to the position from the charging board. The charging board is composed of multiple coils, and each coil has a different degree of magnetic induction with the receiving device in the effective charging area. In order to better manage multi-device wireless charging, a multi-device wireless charging solution needs to be proposed to make the wireless charging system more intelligent, efficient and safe.
由于多设备无线充电技术这几年国内外才开始研究，今后应用领域主要是移动智能设备、穿戴式设备、小型低功率设备等。在多线圈充电板对多设备充电与多设备充电方案的角度出发，有以下论文和专利：Since the multi-device wireless charging technology has only been studied at home and abroad in recent years, the main application fields in the future are mobile smart devices, wearable devices, and small low-power devices. From the perspective of multi-device charging and multi-device charging solutions with multi-coil charging boards, there are the following papers and patents:
论文(Wireless Power Hotspot that Charges All of Your Devices)里阐述了磁共振情况下多线圈充电板对多设备进行充电的示例，接收充电的设备与充电板(发射)的线圈频率都是一样的，以达到共振提高充电效率。此论文中发射与接收是采用帯内通信传递信息，对各信道进行估计，然后采取本论文中提到的最大化功率传输算法对发射线圈的电压进行控制。这个示例给了我们研究参考的方向与证实了多设备无线充电的可行性，但是在充电系统管理和方法上还有很多情景需要我们的进一步研究和探索。The paper (Wireless Power Hotspot that Charges All of Your Devices) describes an example of charging multiple devices with a multi-coil charging pad in the case of magnetic resonance. The charging device and the charging pad (transmitting) have the same coil frequency. Resonance is achieved to improve charging efficiency. In this paper, the transmission and reception use intra-band communication to transmit information, estimate each channel, and then use the maximum power transmission algorithm mentioned in this paper to control the voltage of the transmitting coil. This example gives us the direction of research reference and confirms the feasibility of multi-device wireless charging, but there are still many scenarios in the charging system management and methods that need our further research and exploration.
专利(EP2654049)是公布了多设备无线充电系统的方案。通过把充电板周围划分成充电区、可能充电区和不可能充电区，把在充电区的移动设备分为一组，可能充电区的移动设备为一组，这是一种充电模式。另一种模式是把在充电板频率区的设备为一组，并且以时分的方式对不同频率的移动设备进行充电。还会根据移动设备的电量进行充电选择。此专利对多设备充电进行了优先级的划分，针对不同的条件选择合适的充电方案，但是考虑到给不同频率的移动设备进行时分充电，降低了充电效率，在移动设备满足多种条件下没有解决具体的优先级问题。The patent (EP2654049) is a solution to a wireless charging system for multiple devices. By dividing the surrounding area of the charging board into a charging area, a possible charging area and an impossible charging area, the mobile devices in the charging area are grouped into a group, and the mobile devices in the possible charging area are grouped together, which is a charging mode. Another mode is to group the devices in the frequency zone of the charging pad into a group, and charge the mobile devices of different frequencies in a time-division manner. Charging selections are also made based on the battery level of the mobile device. This patent prioritizes the charging of multiple devices, and selects appropriate charging solutions for different conditions. However, considering that the time-division charging of mobile devices with different frequencies reduces the charging efficiency, there is no need for mobile devices to meet various conditions. Address specific priority issues.
由于单一的无线充电技术已经发展较为成熟，多设备无线充电技术国内外已有很多公司在研究，现有的论文和专利也只是在充电方案上提出了一些简单的解决方案，并没有一个很好的系统和一套解决方案。Since a single wireless charging technology has been developed relatively maturely, many companies at home and abroad have been researching multi-device wireless charging technology. The existing papers and patents only propose some simple solutions on the charging scheme, and there is not a very good one. system and a set of solutions.
