本申请涉及人工电磁材料技术领域，具体而言，涉及一种支持WiFi的智能反射面板、制造方法及供电系统。
背景技术
随着物联网技术的快速发展，如WiFi和蓝牙等无线应用进入日常生活，包括虚拟现实，远程教育医疗，智慧城市和人工智能。这些技术的普及都对无线网络的传输速率提出更高要求，伴随着WiFi6技术的普及和WiFi7技术的逐步商用，无线通信技术面临为更多IOT(Internet of Things)设备提供更高速率，更大带宽的挑战。传统的无线通信形式，即接入点(AP)和客户终端相互收发已经遇到瓶颈。在人工智能，新兴材料和波束赋形技术的驱动下，低功耗，低成本的智能反射面技术成为最有希望应对上述挑战的前景技术。智能反射面是一种集成大量低成本，亚波长结构和独立可控的电磁反射元件的智能平面，可通过软件编程方式对入射信号的反射相位和幅度进行调整，实质是对电容，电感和电阻的调整，从而人为改变电磁波传播方向，提高通信质量，增强系统容量和扩大覆盖范围。智能反射面相当于大规模天线阵列，如果辅助WIFI MIMO(Multi Input Multi Output)技术，针对WiFi6和WiFi7工作频段的5～6GHz电磁波进行反射方向的动态调整，将增强整个系统的通信能力，产生更高的效率。
智能反射面通过调整施加在反射元件的电压实现电磁波反射方向的改变，存在一定的功耗，需要有外供电源。智能反射面板通常部署在户外，如建筑外墙，广告面板和塔架上，这些地方有时候不方便架设供电线路。相关技术中使用的太阳能供电的智能反射面板，智能反射面的基质层为透明材料，接地层也为ITO导电薄膜，在其下粘接太阳能面板，但仍然存在以下问题：1.智能反射面的介质基板和导电材料为透明特殊材料，存在成本和加工方面的问题；2.不同使用场景的智能反射面面板尺寸各不相同，这就需要太阳能面板也要有对应尺寸，增加了太阳能面板加工复杂度；3.二者简单粘接在一起，厚度和重量都有所增加，降低了智能反射面使用的方便程度。

请参照图1，其为本申请一实施例示出的一种支持WiFi的智能反射面板1的结构示意图。一种支持WiFi的智能反射面板1，可以包括：绝缘电介质层100、馈电极200、300-变阻抗器件、400-光伏电池；500-光伏PN结硅片层、600-接地层、700-引线；其中，绝缘电介质层100上方设有馈电极200以及与馈电极200连接的变阻抗器件300，变阻抗器件300通过电压可改变阻抗数值，从而改变对WiFi6和WiFi7 5～6GHz电磁波反射幅度和方向。
请参照图2，其为本申请一实施例示出的馈电极200与变阻抗器件300的连接结构俯视图，同时请结合图1，馈电极200可以包括馈电正极210和馈电负极220，变阻抗器件300设于馈电正极210与馈电负极220之间。
绝缘电介质层100内设有光伏电池400，即光伏电池400被埋设在绝缘电介质层100内。即光伏电池400上方被绝缘电介质层100覆盖。于一实施例中，绝缘电介质层100为SiO 2氧化层。
在绝缘电介质层100下方设有光伏PN结硅片层500；在光伏PN结硅片层500下方设置金属的接地层600。
请参照图3，其为本申请一实施例示出的光伏电池400的俯视图，同时，请结合图2，绝缘电介质层100上设有第一过孔110；光伏PN结硅片层500上设有第二过孔510(图3中未示出)，馈电极200依次穿过第一过孔110以及第二过孔510，与引线700连接。于一实施例中，光伏电池400为梳状结构。
请参照图3，于一实施例中，第一过孔110设为两个，第二过孔510也设为两个，馈电正极210依次穿过绝缘电介质层100上其中的一个第一过孔110，以及光伏PN结硅片层500上其中的一个第二过孔510；馈电负极220依次穿过绝缘电介质层100上其中的一个第一过孔110，以及光伏PN结硅片层500上其中的一个第二过孔510，馈电正极210底部与引线700连接，馈电负极220与光伏电池400的负极共用接地层600。其中，馈电正极210和馈电负极220是由金属铜制作的电极。
上述结构中，光伏PN结硅片层500是将一块P型半导体和N型半导体紧密连接在一 起，这种紧密联系不能有缝隙，是一种原子半径尺度上的紧密连接。结合PN结原理可知，N型半导体中的多子电子的浓度远大于P型半导体中少子电子的浓度；P型半导体中多子空穴的浓度远大于N型半导体中少子空穴的浓度。于是在两种半导体的界面上会因载流子的浓度差发生了扩散运动，随着扩散运动的进行，在界面N区的一侧，随着电子向P区的扩散，杂质变成正离子；在界面P区的一侧，随着空穴向N区的扩散，杂质变成负离子。杂质在晶格中是不能移动的，所以在N型和P型半导体界面的N型区一侧会形成正离子薄层；在P型区一侧会形成负离子薄层。这种离子薄层会形成一个电场，方向是从N区指向P区，称为内电场，当P型和N型半导体结合在一起时，就会在接触面形成电势差，即为PN结。
可见光在光伏PN结硅片层500产生光电流，在梳状电极和接地层600之间形成光伏电池。在变阻抗器件300和接地层600之间包含SiO 2材料的绝缘电介质层100和硅材料的光伏PN结硅片层500，对WiFi6和WiFi7波长为5～6厘米的电磁信号均没有吸收，构成智能反射面板，从而实现WiFi 5～6GHz电磁反射和光伏供电互不干扰，电磁兼容。
请参照图4，其为本申请一实施例示出的智能反射面板1的制造方法流程示意图。一种智能反射面板1的制造方法，用于制造如图1所示智能反射面板1，可以包括如下步骤：
步骤S100：按照预设尺寸，加工硅片。
本步骤中，将单晶硅或多晶硅原材料，按照预设尺寸加工成硅片。其中，预设尺寸可以按照一个独立的智能反射面板1单元的需求尺寸进行预先设计。
步骤S200：在硅片表面注入光伏PN结，形成光伏PN结硅片层500。
本步骤中，在硅片表面以掺杂注入的方式注入PN结，形成光伏PN结硅片层500。
步骤S300：在光伏PN结硅片层500上方铺设光伏电池400，在光伏电池400上方覆盖绝缘电介质层100，在光伏PN结硅片层500下方铺设接地层600。
本步骤中，在光伏电池400上方覆盖SiO 2材质的氧化层，即绝缘电介质层100，使绝缘电介质层100覆盖光伏电池400表面；在制造绝缘电介质层100、光伏PN结硅片层500以及接地层600时，使绝缘电介质层100、光伏PN结硅片层500以及接地层600的结构尺寸保持一致。
步骤S400：在绝缘电介质层100上制作第一过孔110，在光伏PN结硅片层500上制作第二过孔510。
本步骤中，在绝缘电介质层100上制作第一过孔110，贯穿绝缘电介质层100；在光伏PN结硅片层500上制作第二过孔510，并贯穿光伏PN结硅片层500。
步骤S500：在绝缘电介质层100上方铺设馈电极200，并将馈电极200表面安装连接变阻抗器件300。
步骤S600：将馈电极200依次穿过第一过孔110以及第二过孔510，与引线700连接。
于一实施例中，步骤S300具体包括：
在光伏PN结硅片层500的P极上方铺设梳状结构的光伏电池400，在光伏PN结硅片层500的N极下方铺设导电电极作为接地层600。
如前所述PN结的原理可知，当P型(即本步骤中所述的光伏PN结硅片层500的P极)和N型半导体(即本步骤中所述的光伏PN结硅片层500的N极)结合在一起时，在接触面形成电势差，即为PN结。在光伏PN结硅片层500上表面，也就是光伏PN结硅片层500的P极铺设梳状结构的光伏电池400，在光伏PN结硅片层500下表面，也就是光伏PN结硅片层500的N极铺设导电电极，作为接地层600。
于一实施例中，步骤S400具体可以包括：
在第一过孔110、第二过孔510上分别镀铜。在制作完成第一过孔110和第二过孔510后，分别在第一过孔110内和第二过孔510内镀铜。镀铜可提高馈电极200的导电性。
于一实施例中，步骤S500具体包括：
在绝缘电介质层100上方分别铺设馈电正极210与馈电负极220，在馈电正极210与馈电负极220之间连接变阻抗器件300。
在步骤S400中，可以在绝缘电介质层100上制作两个第一过孔110，并均贯穿绝缘电介质层100；在光伏PN结硅片层500上制作两个第二过孔510，并均贯穿光伏PN结硅片层500。从而使馈电正极210依次穿过绝缘电介质层100上其中的一个第一过孔110，以及光伏PN结硅片层500上其中的一个第二过孔510，使馈电负极220依次穿过绝缘电介质层100上其中的一个第一过孔110，以及光伏PN结硅片层500上其中的一个第二过孔510，将馈电正极210底部与引线700连接，馈电负极220与光伏电池400的负极共用接地层600。并在馈电正极210与馈电负极220表面之间连接安装变阻抗器件300。
请参照图5，其为本申请一实施例示出的供电系统2的结构示意图。一种供电系统2，包括多个智能反射面板1、控制器22、驱动电路23以及光伏控制器24。其中，多个智能反射面板1相互拼接形成智能反射面板组21。按照图4所示的智能反射面板1的制造方法，将大量独立单元的智能反射面板1进行拼接，形成智能反射面板组21，图5中所示，智能反射面板组21包括20个独立拼接形成的智能反射面板组21。
其中，控制器22与驱动电路23连接，驱动电路23与智能反射面板组21连接，具体地，各个独立的智能反射面板1上的引线700引出，连接到驱动电路23上。因此，引线700的作用在于接收驱动电路23信号。具体地，智能反射面板组21上的引线700连接驱动电路23，接收控制器22提供的控制信号，并将控制信号转化为驱动信号，通过各个独立的智能反射面板1上的引线700引出，对各单元的变阻抗器件300导通状态独立控制。 控制器22根据对WiFi 5～6GHz电磁波的反射要求，包括反射方向和反射强度，产生对智能反射面板组21的控制信号，并且将该控制信号发送给驱动电路23，完成对智能反射面板组21中的各个智能反射面板1的控制。
智能反射面板组21与光伏控制器24一端连接。光伏控制器24另一端分别与控制器22以及驱动电路23连接，用于提供电能。具体地，光伏控制器24用于收集智能反射面板组21底层产生的光电流，并将光电流转化为直流电源，给整个供电系统2中的智能反射面板组21、控制器22以及驱动电路23提供电能。
于一实施例中，供电系统2还包括：蓄电池25；蓄电池25与光伏控制器24连接，用于接收电能储存。具体地，蓄电池25接收光伏控制器24提供的充电电流，存储多余的电能。在太阳能不足的时候，成为整个供电系统2的备用电池。
本申请的供电系统2中，智能反射面板组21由多个独立的智能反射面板1拼接组成，智能反射面板组21由控制器22经过驱动电路23进行扫描控制。通过对不同智能反射面板1施加高低电平，控制每个独立的智能反射面板1上PIN管的导通状态，形成对WiFi6和WiFi7工作频段5～6GHz电磁波不同的相位延迟，从而控制WiFi6和WiFi7工作频段5～6GHz信号的反射方向。
光伏控制器24收集智能反射面板组21底层产生的光电流，光电流汇聚后在光伏控制器24形成稳定的直流电源，可以提供给控制器22和驱动电路23电能。不同时间太阳光照不均匀，利用蓄电池25可以将光电转换后多余的电能储存下来，在日照不足或负载过大时作为系统的备用电源，提供电能。
于一实施例中，智能反射面板1上的变阻抗器件300为PN管可变电容，馈电正极210、馈电负极220以及第一过孔110和第二过孔510的电镀层为均为铜；光伏电池400的正电极和接地电极为金属铝，光伏电池400采用单晶硅材料。可通过下面的计算方法计算由上述智能反射面板1构成的供电系统2的供电能力：
单晶硅的转换效率η＝16％，按照在25C下光照强度L＝1000W/m 2计算，则单位面积(即Area＝1m 2)光伏面板提供的功率Ps：
P S＝η*L*Area  (1)
即Ps＝η*L*Area＝16(％)*1000(W/m 2)*1(m 2)＝160(W)
设每日平均日照时间长度h s＝8小时，考虑到季节和天气的影响，按照Q＝50％折算则每日提供的电能E：
E＝Q*P S*h s  (2)
即E＝Q*Ps*hs＝50(％)*160(W)*8(hs)＝640(WH)
假设智能反射面板1每日工作时长h w为24小时，则单位面积光伏电池400可以支持 的功耗P IRS:
Figure PCTCN2021134191-appb-000001
即P IRS＝E/hw＝640(WH)/24(hw)＝26(W)
也就是说光伏电池400可以支撑单位面积最大功耗26W的智能反射面板1工作。
以PN管做变阻抗器件300的智能反射面板1功耗主要是PN管导通的电流功耗。单位面积PN管数量和工作频段有关，如WiFi6工作的5GHz工作频段，其单位面积的管子数量约为4000支，总功耗约为2W左右，完全可以满足要求。
于一实施例中，本申请中，可通过修改智能反射面板1的物理参数，例如反射原件类型和密度，也可成为面向2.4GHz工作频段的WiFi或无线物联网等其它频段的应用。
本申请通过将光伏电池400作为电介质基板，在绝缘电介质层100表面铺设馈电正极210和馈电负极220，以及变阻抗器件300，并将馈电负极220和光伏电池400负极连接，实现具备光伏供电功能的智能反射面板1。
本申请的整套供电系统2将光伏电池400作为介质层基板集成在智能反射面板1里，从而具有集成度高，材料简单，加工方便，易于大规模制造和使用。由于省去供电线路，施工安装方便，便于在城市复杂环境下部署，而且节能环保。
需要说明的是，在不冲突的情况下，本申请中的实施例中的特征可以相互结合。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
