3500/22M 138607-01 3500瞬态数据接口(TDI)

3500瞬态数据接口(TDI)是3500监控系统和Bently Nevada的system 1®机械管理软件之间的接口。TDI结合了3500/20机架接口模块的能力和通信处理器(如TDXnet)的数据收集能力。
TDI与M系列监视器(3500/ 40m, 3500/ 42m等)一起在3500机架的RIM插槽中工作，连续收集稳态和瞬态波形数据，并将这些数据通过以太网链路传递给主机软件。静态数据捕获是TDI的标准配置，但是使用可选的通道启用磁盘将允许捕获动态或瞬态数据。除了在3500机架中集成通信处理器功能外，TDI还在几个方面对以前的通信处理器进行了改进。
TDI提供了整个机架通用的某些功能，但TDI不是关键监控路径的一部分，对整个监控系统的正常运行没有影响。每个机架需要一个TDI或RIM。TDI在机柜中只占用一个槽位，始终位于1号槽位(靠近电源)。
对于三模冗余(TMR)应用，3500系统需要TMR版本的TDI。除了所有标准TDI功能外，TMR TDI还执行“监视器通道比较”。3500 TMR配置使用监视器选项中指定的设置执行监视投票。使用这种方法，TMR TDI连续比较三(3)冗余监视器的输出。如果TMR检测到来自其中一个监视器的信息不再等同于(在配置的百分比内)其余两个监视器，它将标记监视器为错误，并在System event List中放置一个事件。

The 3500 Transient Data Interface (TDI) is the interface between the 3500 monitoring system and Bently Nevada’s System 1® machinery management software. The TDI combines the capability of a 3500/20 Rack Interface Module with the data collection capability of a communication processor such as TDXnet.
TDI operates in the RIM slot of a 3500 rack in conjunction with the M series monitors (3500/40M, 3500/42M, etc.) to continuously collect steady state and transient waveform data and pass this data through an Ethernet link to the host software. Static data capture is standard with the TDI, however using an optional Channel Enabling Disk will allow dynamic or transient data to be captured as well. TDI has made improvements in several areas over previous communication processors in addition to incorporating the Communication Processor function within the 3500 rack.
TDI provides certain functions common to the entire rack, however the TDI is not part of the critical monitoring path and has no effect on the proper, normal operation of the overall monitor system. One TDI or RIM is required per rack. The TDI occupies only a single slot in the rack and is always located in Slot 1 (next to the power supplies).
For Triple Modular Redundant (TMR) applications, the 3500 System requires a TMR version of the TDI. In addition to all the standard TDI functions, the TMR TDI also performs “monitor channel comparison”. The 3500 TMR configuration executes monitoring voting using the setup specified in the monitor options. Using this method, the TMR TDI continually compares the outputs from three (3) redundant monitors. If the TMR detects that the information from one of those monitors is no longer equivalent (within a configured percent) to the remaining two, it will flag the monitor as being in error and place an event in the System Event List.
