TPU正常启动,双黄灯熄灭,说明托鱼正常,与托鱼的链接正常
启动SonarPro软件,链接正常,发射后,没有图像,托鱼没有正常的啪啪声
如果换TPU,托鱼有规律的啪啪声,图像正常
根据手册上的说明:
PROBLEM |
CHECK |
No operation, but the LOCK LOSS and Carrier Loss lights are off. |
Ethernet Hub. LAN cables. Path and location path to vxWorks. Network setup on the computer and TPU. |
TPU not functioning properly for no apparent reason. |
Check for proper AC voltage setting. Check AC fuses. Replace boards one at a time. |
After a cable problem and the correction of the cable problem, the CARRIER LOSS and LOCK LOSS lights are on. |
Check the towfish fuse. Check the 200 VDC. Check the TP7 and TP12 waveforms on Multiplexer board. Check the diodes in the hybrid circuit. Replace the Demultiplexer board in the TPU. |
After a cable problem and the correction of the cable problem, the Carrier Loss and Lock Loss lights are off, but the data on SonarPro is breaking up. |
Check that R30 is 4.7 ohms on the Multiplexer board in the towfish. Check U2 on the Demultiplexer board. Change the Demultiplexer board. Check diodes D7, D8, D9, D10 and check that R11 is reading 4.7 ohms on the TPU 200 VDC power supply. |
After a cable problem and the correction of the cable problem, the 200 VDC to the towfish is reading around 300 VDC. |
Check or change U1 on the TPU 200 VDC power supply. |
SonarPro operating slow over the network with jittery display updates and large lag numbers. |
Incompatibility with the TPU CPU and the vxWorks software. Check the CPU version in the TPU and the version of vxWorks software. CPU versions 14103184 can only be used with vxWorks version 5.11.1841 or higher. CPU version 14102073, recognized by unpopulated area near front of board, can only be used with vxWorks version 5.5.0291 or earlier. Contact L-3 Klein technical support for more information. |
TPU will not boot. Error in boot line. Gibberish data. "Can’t load boot file!!" message. Error messages. |
The likely cause is the failure of the backup battery on the CPU board. Contact L-3 Klein for a replacement. See “Replacing the CPU Battery” on page C-62 for battery replacement instructions. |
中文对照:
托鱼正常,拆开TPU盖板,检查电源板
触发信号没有进入托鱼,触发托鱼,肯定信号输入有问题,要么没有输入,或者输入不正确
拔掉了直流电压端子和信号电源端子,量测了电源电压和信号电压,信号电压正常,12V,电源电压是200V,
测量了R11的电阻是5ohms
不知道那儿的问题,偶然之间,采集软件没有停止发射,TPU重启以后,托鱼突然正常发射啪啪声,重启采集软件,图像恢复,莫名其妙。
2、出现问题
一切正常,采集正常,就是没有GPS信号输入,拆开了TPU,找到了定位芯片
RS232输入的Pin的线路图如下:
利用示波器测量输入电平,然后测输出电平,看是否符合设计的电路逻辑,如果不不符合,说明芯片损坏,
通过示波器判断,23针的波形正常,规律方波,GPS信号,而输出22针的波形是一条直线,无信号。判断芯片损坏,查了一下此芯片在淘宝上的价格约20元。
3、安装采集软件SonarPro
之前在(一)碰得到了一个SSL的问题(WIN7下安装SonarPro),主要问题还是FTP配置的问题:
(1)首先要确定Win7操作系统中是否已装好FTP服务器功能,我们点击开始按钮-->控制面板-->程序和功能-->打开或关闭Windows 功能 模块,在弹出的对话框中,点击“Internet信息服务”中查看是否已经勾选FTP服务器,如果没有则勾选之再点确定。
(2)接下来,我们就可以新建一个FTP站点了,在桌面上右击“计算机”图标,在弹出的菜单中,点击“管理”按钮,打开"计算机管理"功能,在弹出的窗体中,点击“服务和应用程序”->"Internet信息服务(IIS)管理器"->“网站”,右击点击“网站”,在弹出菜单中选择“添加FTP站点”
(3)一般为安全起见,在局域网内访问FTP,我们要设定一个访问的用户名和密码,于是在刚刚打开的“计算机管理”页面中,点击“本地用户和组”->"用户",添加一个访问的FTP用户及其密码,如果已有可忽略本步骤
(4)接着右键点击刚新建的FTP站点。在弹出菜单中点击“编辑权限”按钮,在弹出窗体中设置FTP文件夹的属性,在安全页面内设定用户名(test)为完全控制
(5)在FTP站点的“基本属性”内,设置特定用户访问
(6)启用FTP身份验证
(7)设置FTP授权规则
(8)测试FTP是否成功

注意的问题:在测试TPU和电脑的链接时,喜欢ping TPU的IP,这个一般是Ping不通的,只有在TPU启动那几秒钟能ping通
