Android4G专网模块信号的上报过程
Android4G专⽹模块信号的上报过程最近⼀直在调试Android的4G专⽹模块；⼀个困扰了我很久的问题昨天也解决了；就是4G信号强度是怎么报上来的？怎么在右上⾓通知栏显⽰的？现在也清楚了；其实只修改reference-ril.c中的⼀个函数就解决问题了，只是牵扯到很多理解性的东西；static void requestSignalStrength(void *data, size_t datalen, RIL_Token t)函数是上报信号强度的，是上层每隔⼀段时间主动请求下发的函数；注意这个函数中Android4.0（没有validateInput()对信号强度的验证）和Android4.4.3是通过RIL_SignalStrength_v6结构体上报的；framework解析信号强度4G优先解析的是RSRP；ril.h中有注释：RSRP的范围是 * Range: 44 to 140 dBm；注意44信号强度最⼤；140信号强度最⼩；⼏乎所专⽹模块都上报数据不是44~140范围；有的是0~31；有的是0~99；要做相应的转化；不然信号质量格格显⽰不准；[cpp] view plain copy1. typedef struct {2. int signalStrength; /* Valid values are (0-31, 99) as defined in TS 27.007 8.5 */3. int rsrp; /* The current Reference Signal Receive Power in dBm multipled by -1.4. <span style="color:#ff0000;"> * Range: 44 to 140 dBm</span>5. * INT_MAX: 0x7FFFFFFF denotes invalid value.6. * Reference: 3GPP TS 36.133 9.1.4 */7. int rsrq; /* The current Reference Signal Receive Quality in dB multiplied by -1.8. * Range: 20 to 3 dB.9. * INT_MAX: 0x7FFFFFFF denotes invalid value.10. * Reference: 3GPP TS 36.133 9.1.7 */11. int rssnr; /* The current reference signal signal-to-noise ratio in 0.1 dB units.12. * Range: -200 to +300 (-200 = -20.0 dB, +300 = 30dB).13. * INT_MAX : 0x7FFFFFFF denotes invalid value.14. * Reference: 3GPP TS 36.101 8.1.1 */15. int cqi; /* The current Channel Quality Indicator.16. * Range: 0 to 15.17. * INT_MAX : 0x7FFFFFFF denotes invalid value.18. * Reference: 3GPP TS 36.101 9.2, 9.3, A.4 */19. } RIL_LTE_SignalStrength;[cpp] view plain copy1. static int SignalStrengthTransform(int Signal)2. {3. if(Signal == 99){4. return 140;5. }6.7. return (Signal*3 - 140)*(-1); //为了RSRP(44~140)的范围这⾥要根据AT+CSQ上报的值做相应的转换;不然信号显⽰不准确;8.9. }[cpp] view plain copy1. static void requestSignalStrength(void *data, size_t datalen, RIL_Token t)2. {3.

机柜
S7700可以安装于公司主流机柜N66E、N68E中；
如果客户自行采购第三方机柜，要求如下：
1、机柜标准：19'标准机柜，非19’机柜需要客户自行根据设备参数确认可安装性； 2、挂耳安装面到前门内侧最高凸起结构(凸起结构包括双开门机柜的门中缝折边、附属在机柜门里面
的其他结构，以下前后门都指此意思)的距离D1：必须大于95mm（600深），否则可能导致走线后 前门无法关闭；如果小于95mm（600深）不能安装前门，否则不能安装； 3、设备安装面到后门内侧最高凸起结构的距离D2：必须大于500mm，否则可能导致后门无法关闭或 不安装后门； 4、机柜后门开孔率应不小于50%以确保通风，如果如果后门开孔少或者无开孔，需要同整机热设计 专家确认散热可行性； 5、机柜左侧需要保证有相应的通风空间（下图中左侧绿色区域）且有侧门；没有侧门情况下需要保 证机柜左侧没有其他设备；S7700不能安装在左侧有设备且不安装侧门的场景。 6、机柜右侧安装立柱和机柜右侧走线通道之间不允许封闭隔开，以确保安装好后电缆能走到机柜侧 面走线通道内 7、机柜顶端配电盒安装空间：DC 需要3U，AC需要 4U 注意：S7700采用左进风后出风的散热方式，所以要求所有机柜均装有侧门。
9g25+EM770W 3G模块上网实现
9g25 + 3G WCDMA模块上网条件●9G25开发板●3G WCDMA无线模块HUAWEI EM770W、MINI PCI-E转USB转接板●联通3G SIM卡默认情况下linux 3.10.1的内核是不支持华为EM770W WCDMA模块的，将EM770W装到MINI PCI-E转USB转接板上，插到9G25开发板，会在开发板的DEBUG串口打印下面信息，通过下面信息我们可以得到EM770W的厂家ID和设备模块ID，也可以向模块提供商咨询这两个ID号。
厂家ID：0x12d1设备模块ID：0x1404图6 EM770W模块信息1、内核中增加对EM770W WCDMA模块的支持源码位于drivers/usb/serial/option.c增加EM770W设备ID的宏定义HUAWEI_PRODUCT_EM770W图7 EM770W设备ID的宏定义在option_ids中增加对EM770W设备的支持。
图8 option_ids中增加对EM770W设备的支持2、内核配置项开启内核ppp和移植pppd过程同上，将“USB driver for GSM and CDMA modems”设成作为内核模块方式编译，设置完成重新编译内核。
图9内核编译完成后，使用下面命令生成新的驱动#make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- modules交叉编译完成会在drivers/usb/serial/目录生成option.ko、usb_wwan.ko两个驱动文件，将这两个文件拷贝到开发板的/lib/modules/3.10.0+目录，或者其他自定义目录。
3、加载驱动在开发板上使用下面命令加载驱动#insmod /lib/modules/3.10.0+/usb_wwan.ko#insmod /lib/modules/3.10.0+/option.ko注意驱动加载顺序，option.ko要依赖于usb_wwan.ko，驱动加载成功后将EM770W模块插到开发板USB口，如能正确识别打印图10信息，在/dev目录会产生5个ttyUSB*的虚拟USB 口，如图11，使用pppd拨号使用ttyUSB0，波特率115200。

智慧油田中嵌入式RTU应用设计
智慧油田中嵌入式RTU应用设计魏学良;李卓然;于聪智【摘要】在现今油田进行智能化、数字化技术改造的背景下，本文通过运用嵌入式技术和网络通信技术并通过在实验室及油田现场进行实物实验，提出了嵌入式技术的RTU系统总体设计方案，包含硬件支撑平台设计和软件设计。
硬件支撑平台以三星公司的S3C2440的arm为核心处理器并外接功能接口芯片；嵌入式Linux 多任务操作系统作为系统软件平台并在此系统平台上开发应用程序，实现嵌入式RTU的设计。
目前该系统原型机已经实现，通过现场实验表明，本系统性能稳定，各项指标均达到要求。

嵌入式平台下3G网络服务器(3G+PPP+BOA+ARM)
嵌入式linux平台下网络服务器（3G+PPP+BOA+ARM）you_set@一、华为3G模块EM770W在LINUX下的驱动1.EM770W为华为3G WCDMA模块，支持HSPA(HSPA data rate －7.2 Mbps DL / 2 Mbps UL),更适合于无线视频服务器和监控器。
EM770W接口为mini PCIE，52个引脚，引脚中对外数据接口包含一个全串口UART1,一个四线串口UART2，一个USB2.0。
EM770W与ARM芯片连接有两种方式：一种是通过UART1，速度只能达到115.200KBPS，这与HSPA速率明显跟不上，一般不用此方式进行连接，如果和MCU连接进行小量数据传输可以用此方式。
第二种方式是通过USB和ARM芯片连接，此方式适合大量数据传输，速率更快。
2.EM770W在LINUX下的驱动在较新版本的LINUX内核（LINUX-2.6.18以上）里已经有了EM770W的驱动，需在内核增加支持，修改配置如下：在linux内核目录下：make ARCH=arm menuconfig然后重新编译内核，增加驱动后在ARM开发板上通过USB接入EM770W，系统识别出USB设备，将EM770W虚拟成三个串口设备，节点为/dev/ttyUSB0,/dev/ttyUSB1,/dev/ttyUSB2。
如果使用较早的内核而不支持“USB driver for GSM and CDMA modems”的话，可以选择Usb Generic Serial Driver，但是需要把Usb Driver的PID和VID设置成华为的ID（EM700/EM770W的VID： 0x12d1 PID： 0x1001）ID更改步骤：在linux内核目录下vi drivers/usb/serial/option.c在里面定义两个宏(EM770W的VID： 0x12d1 PID： 0x1001）：#define EM770W_OPTION_VENDOR_ID 0x12d1#define EM770W_OPTION_PRODUCT_COLT 0x1001增加到结构体中static struct usb_device_id option_ids[] = {{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_COLT) },…{ USB_DEVICE(EM770W_OPTION_VENDOR_ID , EM770W_ OPTION_PRODUCT_COLT) },}修改完成后重新编译内核就可以驱动EM770W了。
