LAN-XI 数据采集

我们的 LAN-XI 数据采集系统是一个多功能的 DAQ 硬件、模块和设备系列,设计灵活、坚固耐用且易于使用。

  • 灵活的通道配置
    我们的 LAN-XI 模块可单独运行,并配有电池供电模块,您可以创建小型、坚固耐用的低通道数系统。各种输入和输出 DAQ 模块可组装成 5 个或 11 个模块的机箱。

    这些机箱可以组合在一起,形成一个拥有 1000 多个通道的采集系统。
  • 分布式系统
    我们的 DAQ 模块可单独分布在靠近测试对象的地方,以保持传感器电缆较短,避免噪音和电缆缠绕。通过同时提供以太网供电(PoE)的 LAN 电缆连接。

    这些测量模块为飞行噪声认证测试、地面振动测试(GVT)、汽车通过测试和船舶自噪声监测(SNMS)等大规模测量提供了理想的系统。
  • 通用性
    多用途和灵活性是 LAN-XI 的核心。您可以轻松拆卸模块,将数据采集系统拆分开来进行单次测量,或者在需要进行大型测试时将模块组合起来。

    您可以安装多种不同类型的输入面板,连接您所选择的传感器。如果您的需求随着时间的推移而发生变化,您可以轻松添加额外的模块或专门的多通道转接头,以实现更快的数据采样率或桥路传感器。
  • OPEN-API 协议(包含许可证)
    LAN-XI Open API 是一个轻量级、独立于平台的接口,用于从您自己(或第三方)的软件对 LAN-XI 数据采集硬件进行编程。LAN-XI Open API 接口是基于 REST 和 JSON 的协议。

LAN-XI Light modules are tough data acquisition units that capture time data from up to four channels, and are ideally suited for use with BK Connect Applets, specific tools for specific tasks. All LAN-XI Light modules can be used together with Battery Module Type 2831 and Wireless LAN Frame Type 3660-A to create a portable, remote recorder. 

The default configuration of LAN-XI Light Type 3677 (4-channel input and one channel output) data acquisition module uses Front Panel UA-3100-041, which has four BNC connectors and one BNC output channel that can be used as a signal generator with frequency range from 0 to 25.6 kHz. However, Type 3677 can also use optional Front Panel UA-3102-041 to support 200 V microphones requiring 7-pin LEMO connectors.

The signal generator can be easily set up using BK Connect, controlling excitation type, frequency parameters, output level, level ramp up/down times, and burst excitation. The software supports sine (fixed frequency), stepped sine, continuous and burst random, periodic and pseudo-random, white noise and user-defined waveforms.

USE SCENARIOS

  • Any general sound and vibration recording and analysis, such as troubleshooting, where a single, four-channel module meets channel-count needs 
  • Production quality testing of consumer goods, such as quick pass/fail measurements according to a tolerance curve
  • Noise, vibration and harshness (NVH) recording under demanding conditions such as on a motorcycle on a vehicle test track
  • Battery-operated recording in the field, such as traffic noise
  • Evaluating sound quality metrics (loudness, sharpness and articulation index)
  • Generator output for structural testing such as modal analysis

CHARACTERISTICS

LAN-XI Light’s buttons and LCD screen can be used for control and feedback. LED rings around each channel indicate its status by color. Available memory and overload displays are shown on the LCD screen.  

CAPABILITIES

  • DC to 25.6 kHz input range (sampling rate 65.5 kHz) 
  • Transducer conditioning is automatically configured when using transducers with TEDS
  • Built-in home page allows remote set-up with any PC, tablet or smartphone
  • Data transfer and PoE over LAN connection
  • Powered by battery, mains, external DC, or power over Ethernet (PoE)
  • Seven-hour battery can be swapped in the field
  • Output channel with full generator functionality – from 0 to 25.6 kHz 
  • Also available: LAN-XI Open Application Protocol Interface (API) – a lightweight, platform-independent interface for programming LAN-XI data acquisition hardware from your own (or third party) software.
