技术说明

紧凑型的集成套CR3000,含有测量控制电子单元、通讯端口、16-键键盘、LCD显示器、供电电源以及手提把手,非常便携。一体式LCD显示器128x64像素绘图式或8行字符数值显示的功能。

CR3000有3种底座选项:碱性电池底座、可充电电池底座、无电池底座。CR3000的功耗非常低,配一块太阳能板给它的电池充电,就可以让CR3000一直工作,从而不需要交流电源。为了减小非精确测量的可能性,当主电源低于 9.6 V时,CR3000会暂停工作。

内部的操作系统包括数据采集器编程所需的测量、处理、输出指令。编程语言为CRBasic,使用类BASIC语法。测量指令包括:电桥设置、电压输出、热电偶、脉冲/频率信号。处理指令包括:代数运算、统计及用于现场处理的超越函数。输出指令按时间段处理数据,或控制外部设备。

Additional Compatibility Information

传感器

CR3000 包含数种类型的通道,可支持几乎每种可用的传感器,包括:热电偶、SDI-12 传感器、和 4 到 20 mA 传感器等。定制的ASIC (特定应用相关的集成电路) 芯片扩展了CR3000的脉冲计数、控制口和串行通讯的功能。CR3000的 I/O 端口 (控制口) 可以成对分别作为接收和发送使用,允许与串口传感器和设备进行通讯。

测量和控制外设

CR3000 可兼容我们所有当前的 CDMs (需要一个 SC-CPI接口模块),SDMs,扩展板,振弦接口模块,端子输入模块和继电器等。

通讯

CR3000 与 PC 之间的通讯可以通过多种方式进行,包括:直接通讯,以太网接口 (NL100, NL115, NL120),多子站总线 modem,直拽 modem,电话 modem (固话、数字手机网络和语音合成电话),射频电台通讯,和卫星发射器 (Argos、高数据速率的 GOES 以及 Meteosat)。

查看数据可通过集成的键盘显示器,iOS 或 Android 设备 (需要 LoggerLink软件),CD295 DataView II 显示器,Archer-PCon 现场 PC,或用户提供的 PDA (需要 PConnect 或 PConnectCE 软件) 进行。

兼容的外部数据存储设备包括 CFM100,NL115 和 SC115。

机箱

CR3000 能够被安放在 ENC12/14、ENC14/16、ENC16/18、ENC24/30 或 ENC24/30S 防护机箱内。

供电

CR3000 一般由自身的碱性电池或可充电电池供电电源 (见 订购栏)。当使用可充电电池时,它内部的 7 A h 密封可充电电池需要通过汽车电瓶 (需要 DCDC18R)、太阳能板或交流充电源来充电。

CR3000 还可以搭配不带电池的底座,这时需要用户提供直流电源。当系统的功耗要求较大容量的电池时,或当要求数据采集器的所占空间更小重量更轻的优点时,优先使用不带电池的底座。

下载

CR3000 OS v.32.03 (4.91 MB) 13-08-2018

Execution of this download installs the CR3000 Operating System and Compiler on your computer.  It also updates the CR3000 support files for the CRBasic Editor.  

Note: The Device Configuration Utility is used to upload the included operating system to the datalogger.

Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive.  This is due to a change in the format of the file system from FAT16 to FAT32.  In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32.  Any programs stored and running from the CPU drive will be lost.  It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.).  In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.

Watch the Video Tutorial: Sending an OS to a Local Datalogger.

In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.

常见问题解答

CR3000: 159

展开全部收起全部

  1. Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:

    • YY is the year.
    • MM is the month.
    • DD is the day.
    • XX is the manufacturing plant.

    This indicates the age of the battery.

  2. Yes, but only if all the other data loggers are PakBus devices, such as the CR800, CR850, and CR1000.

  3. 是,使用下面的步骤:

    1. 使用键盘,按下面菜单操作:Configure, Settings (配置,参数) | Display (显示) | Timeout (min) (超时,分钟):.
    2. 选择 Enter (回车键)。
    3. 键入想设置的超时分钟数值。
    4. 再次选择 Enter (回车键)。
  4. CR3000 能够测量 ±5 V 范围内的模拟电压信号。若传感器的输出超出了这个范围,可以使用电压分压器来使得落在CR3000的电压在 ±5 V 范围。CR3000 可能通过不同的通道供电给传感器,包括:电压激发和电流激发、连续模拟输出、调制 5 V、非调制 12 V 和 开关 12 V。

  5. 这依赖于电池的平均电流消耗,以及是否有太阳能板或市电充电源连接到底座上。请查看我们的技术文档 "Power Supply" (供电电源) 应用说明,寻找关于确认平均电流消耗的指导方法。

  6. 典型的原因如下:

    • DevConfig 的版本太老。 
    • CR3000 有供电问题。
    • 在DevConfig 中选择了错误的 COM1…COM4 端口。
    • USB-到-串口 适配器的驱动设备未被发现。 
    • CR3000 被损坏。 

    如果 CR3000 的显示器工作正常,那么有可能通讯故障来自软件版本、或参数设置、或连接线缆的故障。

  7. Yes. Contact Campbell Scientific for replacement pricing and availability.
  8. 通过数据采集器支持软件来同步每一个数采的时钟到计算机,是最简单的方法,且在很多应用中效果很好。在 LoggerNet 中可设置自动时钟检查,只要用户定义的时钟偏差被检测到,软件就会重新同步数据采集器的时钟。在高速应用中,可取的方式可能是连接 GPS 设备到每一台数据采集器,并使用 GPS 指令来设置数据采集器的时钟。

  9. 充电时间依赖于平均电流消耗和环境条件而不同。一般而言,如果电池放电没有超过其容量的20%,那么使用市电充电源仅花费2到3小时就能完全充满电池。

  10. 是。12 V 端子配有热保险,允许输出 900 mA @ 20°C,650 mA @ 50°C,以及 360 mA @ 85°C。
