Description

接地调整方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及接地调整方法及装置。
背景技术
随着终端(例如：手机)使用环境的多样性，电子设备自身结构的复杂性，电子设备在长期使用过程中，由于跌落或者翻滚造成的自身结构的松动，导电接地材料的老化，腐蚀，变形而导致接地性能恶化。因此，智能移动终端在使用过程中，接地性能的检测和处理的功能需求变得尤为重要。
同时，由于射频频段的多样性，手机内天线越来越多，手机内除了2G/3G/4G主射频天线外，还有其他无线天线如无线保真(Wireless Fidelity，简称为WiFi)，BT，全球定位系统(Global Position System，简称为GPS)，数字电视(Digital Television，简称为DTV)，近场通信(Near Field Communication，简称为NFC)天线，而由于各种干扰的影响，如果手机接地屏蔽不好，会极大的影响到手机的发射接收性能，进而影响用户的呼通率，通话质量，上网速率。所以手机的屏蔽接地处理也是必要的。
另外，手机硬件电路及天线在调节过程中，是基于一定的参考地平面来调试的。而接地方式有很多种，如单点接地，多点接地，如果参考地发生改变，手机天线的有源效率就会改变，进而影响到天线性能及用户的信号质量，所以参考地平面的一致性也显得非常重要。
现如今，手机常用接地方式及检测方法有如下几种：1.通过专门的接地测量仪，如检测平台，检测系统，检测装置。2.电力系统中输电线接地的的监测。3.通过万用表检测接地装置。4.固定导电泡棉或导电布，铜箔等的接地。5.手机弹片或者夹子的接地。6.通过接地线直接单点或者多点接地。7.通过小孔或者大孔直接打孔到地。
对于方式1，专业接地检测装置的使用，系统比较庞大，不便携。对于方式2，一般也专业的电力系统中的接，不同于微电子终端设备的接地。对于方式3，采用的传统的万用表测量来检测电阻来检测，方法复杂，使用条件有局限性。对于方式4，接地材料为导电泡棉或者导电布等，稳定性差，极易变形。对于方式5，接地材料为金属弹片或者夹子，体积大，使用条件苛刻。对于方式6和7，接地形式单一，不可更改，接地性能是否合适未知。
针对相关技术中，无法对终端的接地状态进行检测和调整的问题，还未提出有效的解决方案。

针对相关技术中存在的上述问题，下面结合可选实施例进行说明，在本可选实施例中结合了上述可选实施例及其可选实施方式。
本可选实施例提供了一种安全、稳定、智能及高性能的移动终端多模接地检测及校准调整系统，通过硬件模块搭建的多种接地模式的结合，以保证终端能智能的检测接地状态，并采取对应的措施和模式来调整接地性能。
本可选实施例采用以下技术方案，本可选实施例的系统包括：多点接地端子，接地检测模块、接地处理控制模块、基带芯片、接地诊断模块、自适应调整控制模块、接地不良调整模块、屏蔽不良调整模块、接地形式切换模块、天线接地优化模块、射频芯片模块、液晶显示器(Liquid Crystal Display的简称LCD)显示模块，天线模块，用户界面(User Interface，简称为UI)检测窗口。
本可选实施例的基本过程如下：当用户在UI检测窗口中开启接地处理控制模块后，手机进入接地检测界面，用户通过点击UI界面上的各接地图形化窗口，随机激活各监测端口，手机将各监测端口的点对点接地端子导通，形成接地检测回路，接地检测回路测试当前接地回路参数，并将具体数值反馈给基带芯片，转换为对应的接地参数，接地诊断模块对接地参数的类型做具体的判断，并和标准值及门限做比较，如果超出阈值门限，表明该端口接地恶化，随机启动自适应调整控制模块对改点进行自校准，调整模块会根据当前接地条件和测试值做出实时调整，并重新检测直到修复。如果接地状态恶化到不能直接软硬件修复，或当前的模式无法直接修复，UI窗口中会显示接地状态提示信息及建议，用户或装机维修人员可以根据提示信息针对不良接地点进行拆机专门修复。当用户开启自适应接地调整控制模式后，手机会实时检测当前接收信号强度，调整天线及相关电路接地端子的连接，向提升性能的方向优化接地连接形式。当手机监测到当前手机信噪比恶化或Ec/Io波动异常时，手机也会调整各屏蔽点接地端子的接地形式，向提高手机屏蔽性能稳定性的方向调整。
图7是根据本发明实施例的实现智能接地终端的硬件结构图，如图7所示，该移动终端包括l1多点接地端子，l2接地检测模块、l3接地处理控制模块、l4基带芯片、l5接地诊断模块、l6自适应调整控制模块、l7接地不良调整模块、l8屏蔽不良调整模块、l9接地形式切换模块、l10天线接地优化模块、111射频芯片模块、112LCD显示模块、l13天线模块、114UI检测窗口。
多点接地端子l1，与上面所述接地检测模块l2、接地处理控制模块l3及各接地调整模块l7-l10相连，设置为完成各接地点接地参数的采集。手机在电路板，天线及结构件之间的关键部位设置多点接地端子，端子前端至于接地材料或接地线与参考地点两侧，后端串联微型开关连接，根据接地触点的多少可以对应选择低插损的单刀单掷或单刀多掷开关，开关通过两线MIPI接口连接到基带芯片统一控制，当开启接地处理控制模块后，用户在LCD屏幕上的UI检查窗口中，点击选择对应接地点的端子图标后，接地检测模块将对应接地端子切换到导通状态，即可通过接地检测模块采集该点接地参数及性能状态。
接地检测模块l2和多点接地端子l1、接地处理控制模块l3及基带芯片l4相连，设置为完成各接地参数的检测。接地检测模块通过直接和间接两种检测模式。接地参数可以是接地电阻，接地电流，接地电压。
直接接地检测模式通过检测单个接地回路中的接地参数值，将其结果传输给基带芯片做进一步分析转换处理，从而得到对应端子的接地电阻值。接地检测模块要求检测精确度高，误差小，同时具备良好的频率响应特性，能够同时监测射频的高中低各频段中的接地参数。检测的具体方法如下：接地检测模块首先选取最近接地回路，检测回路先做自校准，将测试回路调整到零电位状态，并检测参考主地端子是否满足要求，然后接通测试端口，测试此时的电流或电压值，再跳过测试端子，通过可变电阻器调节电流或电压值到连接待测接地端子状态，则此时调节的最终的等效电阻就是待测的接地电阻。在检测电路中，会根据测试的步进精度要求调整回路内阻值，同时也会切换参考接地点位置采集接地电阻值，最终的接地电阻值是多个回路和多次测量均值，以防止误测并提高检测精度。
间接接地检测模式通过采集当前各射频模块的频点杂散信号，将其送入手机射频芯片解调，基带芯片处理，得到对应的信号强度幅值，此模式可以采集手机使用频段的带内，带外杂散，以及倍频及小范围内谐波信号，手机在此模式下需要切换到宽频滤波器及陷波器，将其主频滤去，紧留下待检测信号，如果检测到有异常频点或过量杂散毛刺信号，则可以将此结果发送给接地诊断模块，做进一步的处理。同时，间接接地检测模式还实时检测反映当前手机信号质量的关键参数，如接收的信号强度指示 (Received Signal Strength Indication简称为RSSI)，信噪比(Signal Noise，简称为SNR)，导频信号的信噪比Ec/Io等，通过收集这些信号的跳变规律和频率，并与存储的正常标称值和比较，以将这些异常信息传递给接地诊断模块，以作最终判定处理。
最后，间接接地检测模式还负责采集手机内温度参数，通过内置于手机内多个高发热地带的热敏电阻来实现，热敏电阻放置在高发热区域的接地点附近，热敏电阻将采集到的参数发送给基带芯片下一步处理，转换为具体的发热温度值，如果温度异常，超过此处设置的阈值，且表明此处接地不良，需要做接地优化调整。
接地处理控制模块l3和多点接地端子l1，接地检测模块l2，基带芯片l4、接地诊断模块l5及自适应调整模块l6相连，设置为完成整个接地检测、诊断及自适应处理的开启及关闭。接地处理控制模块首先控制基带芯片在检测模式和正常工作模式之间切换，整个手机可以在单一正常模式下工作，也可以在单一检测模式下工作，还能在上述两种模式共存下工作，检测控制模块可以由用户在UI界面上的接地检测界面框里直接设置。同时，接地处理控制模块也负责实时监控当前采集到的各接地端子的接地参数的动态变化，控制自适应调整模块采取对应的调整措施。
基带芯片l4与接地检测模块l2、接地处理控制模块l3、接地诊断模块l5，射频芯片模块l11及LCD显示模块l12相连，主要负责各模块的协调控制及计算，以及接地检测模块采集后数据的数字处理。包括接地参数的计算，RSSI接收信号强度的统计，接收信号码功率(Received Signal Code Power，简称为RXCP)接收信号电平的统计，Ec/Io及SNR等信噪比参数的统计，并将统计计算结果发送给接地诊断模块，实时跟踪当前各系统参数工作状态。
接地诊断模块l5与基带芯片l4，接地处理控制模块l3、自适应调整模块l6相连，完成对各端子接地参数的详细诊断分析。包括接地良好程度评估，接地屏蔽效果评估，接地形式合理性评估，接地对天线性能影响评估等。接地诊断模块根据基带芯片的采集到的接地数据首先判断接地端子的在手机中所处的部位，判断是各部件和结构件之间的接地，如LCD、触摸屏、镁铝合金支撑板，摄像头，通用串行总线(Universal Serial Bus，简称为USB)等，还是在屏蔽筋上的接地，还是电路中电源电路、去耦电路，关键射频电路的接地，或者是天线馈点及净空区域的接地，将判断结果传递给自适应控制模块，以做相应的接地调整处理。然后，接地诊断模块将测试到的接地参数和该部位的标称值相比较，如果超出阈值门限范围，则对其进行诊断结果输出，如某部位要求接地电阻小于0.5欧姆，则查过此值的接地都判定为不良。接地诊断模块还可以判段当前接地端子的具体接地类型，如模拟地，数字地，单点接地，小孔接地，大孔 接地，主参考地还是非主参考地等，并结果接地参数及手机其他信号参数做出具体的诊断结果及解决措施。
自适应调整控制模块l6与接地诊断模块l5及各接地相调整模块l7-l10相连，主要完成各接地模块的自适应调整控制。自适应调整控制模块根据接地诊断模块的输出结果，如果已经判断出是结构松动或者装配不良导致的接地不良，则启动接地不良调整模块进行调整，如果用户或装配人员整改后还是不良，则预警提示显示到LCD对应窗口上，动态显示该位置节点和具体接地参数；如果是已经判断出是屏蔽接地不良，则启动屏蔽不良调整模块，切换和更改接地点，或者增加接地端子数目，让接地点在屏蔽筋周围能加大接地力度；如果是已经判断出是关键电路接地，则启动接地模式切换模块，通过监测各手机信号质量参数，切换各接地模式，并根据射频及基带芯片的汇报值做动态的优化调整；如果是已经判断出是天线相关接地端子，则启动天线优化接地模块，调整天线地馈点的接地点位置，或者多点接地，再通过监测当前天线性能相关参数，做自适应的反馈调整。
接地不良调整模块l7与自适应调整控制模块l6，多点接地端子l1及LCD显示模块l12相连，主要完成接地不良的优化调整。当该模块启动后，手机先尝试去对不良接地点附近端子进行自适应切换调整，更改接地位置和属性，然后再测试是否满足要求，如果不能满足阈值要求，该调整模式会给出其他整改建议，如对该点进行压合，螺丝加固，或者送维修结构维修，更换或者加贴导电材料如泡棉，导电布，铜箔等。
屏蔽不良调整模块l8与自适应调整控制模块l6、多点接地端子l1及LCD显示模块l12相连，主要完成对屏蔽不良的接地点进行调整。当该模块收到自适应调整控制模块的调整指令后，随即控制各端口开关切换接地位置，更改接地点，同时增加导通置于屏蔽筋上的接地端子数目，让接地点在屏蔽筋周围能加大接地力度，并将调节结果显示在LCD的UI检测窗口上。
接地形式切换模块19与自适应调整控制模块l6、多点接地端子l1及LCD显示模块l12相连，完成对各接地端子接地形式的切换。由于手机电路系统中接地形式多样，如模拟地，数字地，单点接地，多点接地，小孔接地，大孔接地，主参考地还是非主参考地等，而不同接地形式对手机的单板及整机射频性能都有很大的影响，不合适的接地形式在单板设计之初往往不能发觉，进而影响到手机的灵敏度和信噪比等关键指标，而由于手机个体自身差异大，接地形式的影响也不尽相同，而接地形式切换模块可以根据自适应调整控制模块的实时监测结果，更改接地形式到更适合手机自身性能的方式上，可以极大的提示手机整体通话能力及抗干扰能力。接地形式切换的方法如下：先根据对应电路或者接地线路所处的位置判定原来接地形式，然后调整接地回流 环路大小或者更改公共阻抗接地点，通过设置在接地点的各个分支和开关，将原有的接地回路链路途径改变，切断或者连通，或将并联单点和串联单点接地相互切换，或者单点接地改成多点接地，多点接地改成单点接地，或者将地线接地切换成大小地孔直接接地等。再切换上述接地方式后，再通过监测接地检测模块，看校准优化调整是否有效，以做下一步自适应控制调整，并将调节结果显示在LCD的UI检测窗口上。
天线接地优化模块l10与自适应调整控制模块l6、多点接地端子l1，天线模块113及LCD显示模块l12相连，完成对各天线性能的接地优化。天线接地优化模块主要分为两部分，直接对天线接地馈点的调节和对天线周边接地环境的调节。对于前者，通过在手机天线电路上设置多个接地回路，通过开关灵活调节导通或者关闭，在实际调试和用户使用中，可以结合当前天线形式和需要，做进一步的优化调整。对于后者，当天线周边接地环境发现变化时，手机整机性能就会降低，天线接地优化模块会检测到恶化的对应位置，导通其他辅助接地回路，以提升整体接地性能，并将调节结果显示在LCD的UI检测窗口上。
射频芯片模块l11与基带芯片l4、天线模块l13及接地检测模块l2相连，主要完成各接地相关射频信号的解调，将采集到的射频信号参数反馈给基带芯片，然后基带芯片把检测到的接地参数和射频参数送给接地诊断模块做系统分析，以采取对应的接地调节措施。
LCD显示模块l12与基带芯片l4、UI检测窗口及各接地调整模块l7-l10相连，配合基带芯片内的信号质量检测，主要完成接地处理控制模块的UI开启，接地检测点分布显示，各接地调整模块反馈的检测结果显示及校准整改措施提示。
UI检测窗口l14与LCD显示模块l12相连，设置为开启接地处理控制模块及激活各接地端子图形化窗口。当用户在UI检测窗口中开启接地处理控制模块后，手机进入接地检测界面，用户通过点击UI界面上的各接地图形化窗口，随机激活各监测端口，手机将各监测端口的点对点接地端子导通，形成接地检测回路，接地检测回路测试当前接地回路参数，并将具体数值反馈给基带芯片，转换为对应的接地参数，并将测试值及其他信息显示在UI对应子窗口上。
