Description

无线通信模块调整方法
技术领域
本发明涉及通信领域，尤其涉及一种能够进行温度和功率补偿从而胜任高度和低温环境的无线通信模块调整系统及其调整方法。
背景技术
随着科技发展，无线通信在人们日常生活中得到了广泛的应用。例如，手机，笔记本电脑，平板电脑，银联刷卡机等都支持使用无线通信协议进行通信。然而，目前的各种电子产品的无线通信模块不能胜任高温和低温等恶劣环境。
发明内容
本发明的目的是提供一种能够进行温度和功率补偿从而胜任高度和低温环境的无线通信模块调整方法。
为解决本发明的技术问题，本发明提供一种无线通信模块调整方法，包括如下步骤：
S1.无线通信模块的温度感测电路感测环境温度并输出感测电压ADC到所述无线通信模块的主控处理器，所述主控处理器检测所述感测电压；
S2.所述主控处理器根据当前感测电压值计算得到成相应的温度值；
S3.通过高低温箱校准当前温度，使得ADC与温度对应关系更准确；
S4.计算机通过串口线与所述无线通信模块连接，读取所述无线通信模块内部默认的自动频率控制AFC和/或自动功率控制APC参数，通过无线综测仪控制非信令模式发射，测试当前所述无线通信模块的频率误差并调节所述无线通信模块的AFC值和/或APC值，直到频率误差在0左右，记录此时的温度与AFC值和/或APC值；
S5.通过多次测量各组不同温度与AFC值和/或APC值，所述计算机生成数据组录入所述主控处理器的寄存器中；
S6.完成调试与校准，以后在各组温度中，通过感测电压检测，所述主控处理器自动调用所述寄存器里面的数组，设置合适的AFC值和/或APC值。
与现有技术相比较，本发明无线通信模块调整方法能够感测环境温度并通过主控处理器进行相应的温度或功率调整，从而使得无线模块能够适应高温或低温等各种恶劣环境。
附图说明
图1是本发明无线通信模块调整系统的一个实施方式的方框示意图；
图2是图1所示无线通信模块的方框示意图。
具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明提供一种无线通信模块调整系统，包括无线通信模块、计算机和无线综测仪，所述无线通信模块包括温度感测电路，所述温度感测电路用于感测环境温度，所述计算机用于读取无线通信模块内部参数，所述无线综测仪用于根据所述内部参数测试并调整频率误差，完成调整后，所述无线通信模块根据温度值和对应的调整后的参数值进行自动设置。
请参阅图1，是本发明无线通信模块调整系统一个实施方式中的方框示意图。所述无线通信模块包括主控处理器10和温度感测电路20，所述温度感测电路20感测环境温度并输出感测电压(ADC)到所述无线通信模块的主控处理器(MCP)的带有电压检测的功能脚上。所述温度感测电路30包括热敏电阻R10，所述热敏电阻R10电阻值随着环境温度改变而改变，从而所述感测电压随之改变。
所述无线通信模块温度调整方法详细描述如下：
S1.主控处理器检测所述感测电压；
S2.主控处理器根据当前感测电压值计算得到成相应的温度值；
S3.通过高低温箱校准当前温度，使得ADC与温度对应关系更准确；
S4.计算机(PC)通过串口线与所述无线模块连接，读取所述无线通信模块内部默认的自动频率控制(AFC)和/或自动功率控制(APC)参数。通过无线综测仪控制非信令模式发射，测试当前无线通信模块的频率误差并调节AFC和/或APC值，直到频率误差在0左右，记录此时的温度与AFC值和/或APC值；
S5.通过多次测量各组不同温度与AFC值/APC值，计算机生成数据组录入主控处理器的寄存器中；
S6.完成调试与校准，以后在各组温度中，通过感测电压检测，主控处理器自动调用寄存器里面的数组，设置合适的AFC值/APC值。
这样，就可以在各种温度中，所述无线通信模块不至于频率误差过大而导致不注册网络或者掉线。
在本发明其他或进一步实施方式中，还可以通过同样的原理实现功率调整和补偿。在无线通信系统中，无线通信模块通过自动功率控制(APC)来控制射频功率发射的。与频率误差的温度补偿方法类似，在高温或低温下读取当前的功率和APC，然后对比在常温下的功率和APC，算出误差。此误差作为补偿值，记录到MCP的寄存器中。然后在无线通信模块工作中，通过温度检测，调出当前的APC补偿值，对高温或低温的功率进行补偿。
本发明无线通信模块调整系统及其温度调整方法中，感测环境温度并通过主控处理器进行相应的温度或功率调整，从而使得无线模块能够适应高温或低温等各种恶劣环境。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
