BENTLY NEVADA本特利 3500/22M 瞬态数据接口前后卡件

BENTLY NEVADA本特利3500/22M 瞬态数据接口前后卡件3500瞬态数据接口（TDI）是3500监测系统和本特利内华达 System 1TM 机械管理软件之间的接口。TDI结合了3500/20框架接口模块（RIM）和通讯处理器，如TDXnet的功能。

TDI运行在3500框架的RIM插槽中，与M系列监测器（3500/40M、3500/42M等）配合使用，连续采集稳态和瞬态波形数据，并通过以太网将数据传送到主计算机软件。TDI具有标准的静态数据采集，但是采用可选的通道使能磁盘，也可采集瞬态或动态数据。TDI与以前的通讯处理器相比，除了将通讯处理器的功能集成到3500框架以外，还有其它几方面的改进。

TDI为框架提供通用功能，但并不是关键监测通道的组成部分，不影响整个监测系统的正确和常规运行。每个框架要求一个TDI或RIM。TDI只占用框架中的一个槽位，须位于一个插槽中（紧邻电源模块）。

对于三重模块冗余（TMR）应用，3500系统要求TMR形式的TDI。除了标准TDI的功能，TMR TDI还具有“监测器通道比较功能”。通过选择监测器选项的安装功能，3500TMR组态执行监测表决功能。采用这种方式，TMR TDI连续比较三个冗余监测器的输出。

如果TMR TDI检测出其中一个监测器的输出信息与其它两个监测器不相等（在组态的百分比之内），它就会向监测器发出错误指示。

The BENTLY NEVADA Bentley 3500/22M Transient Data Interface Front and rear card 3500 Transient Data Interface (TDI) is the interface between the 3500 monitoring System and the Bentley Nevada System 1TM machine management software. TDI combines the capabilities of 3500/20 Framework Interface Modules (RIM) and communication processors such as TDXnet.

The TDI runs in the RIM slot of the 3500 frame and is used in conjunction with the M Series monitor (3500/40M, 3500/42M, etc.) to continuously collect steady-state and transient waveform data and transmit the data to the main computer software via Ethernet. TDI has standard static data acquisition, but enables the disk with an optional channel to also capture transient or dynamic data. In addition to integrating the capabilities of the communication processor into the 3500 framework, TDI has several other improvements over previous communication processors.

TDI provides common functionality to the framework, but is not part of the critical monitoring channel and does not affect the correct and regular operation of the overall monitoring system. Each framework requires one TDI or RIM. The TDI occupies only one slot in the frame and must be located in one slot (next to the power module).

For triple module redundancy (TMR) applications, the 3500 system requires TDI in the form of TMR. In addition to the features of the standard TDI, the TMR TDI also has a "monitor channel comparison function." The 3500TMR configuration performs the monitoring voting function by selecting the installation function of the monitor option. In this way, TMR TDI continuously compares the outputs of three redundant monitors.

If TMR TDI detects that the output of one monitor is not equal to that of the other two monitors (within a percentage of the configuration), it will issue an error indication to the monitor.
