imc CRONOSflex: input modules

As part of the imc CRONOS family, the new imc CRONOSflex continues the tradition for supporting direct measurements of virtually any sensor available for mechanical, electromechanical, and mechatronic measurements. Multi-channel mixed signals, whether analog inputs, counters and incremental encoder inputs, or field bus based signals such as CAN-bus, GM LAN or LIN… you name it: imc CRONOSflex measures it.

Modular measurements
With up to 100kSps per channel, and now supporting up to 2 million samples per second throughput in each base unit, as well as having software configurable high precision signal conditioners and integrated sensor power supplies - the imc CRONOSflex can take on even the toughest data acquisition challenges, while performing at high precision under demanding environmental conditions.

The most striking feature of the imc CRONOSflex system is the imc Click Mechanism - you can add or remove signal-conditioned analog input channels from your imc CRONOSflex system in seconds by simply "clicking" a module on or off the stack. The module's rigid case and automatic recognition by the imc STUDIO software provide the ultimate in flexible modularity. Alternatively, the imc CRONOSflex Modules may be distributed, connected with the base unit or other satellite blocks via standard Ethernet cable.

As with all imc data acquisition system inputs, the imc CRONOSflex Modules integrate signal conditioning, analog filtering, high precision 24-bit digitizers, and digital signal processing. As such, a variety of modules are available from imc—from the general purpose universal 8-channel UNI2-8 module (CRFX/UNI2-8), to more measurement specific modules.

 应用案例：FORD 变速箱测试站

 


在城市道路交通中，变速箱和汽车其他传动零件的应力很大。为检测薄弱点以洞察变速箱的生命周期，德国FORD花了最大功夫在测试变速箱上。在它最新装备的自动测试台，在科隆的FORD选择了imc科技去采集和评价测量的数据。


对测试台的要求非常高。高达10通道的采样率500Hz是必然要求。除此之外，对特定信号事件需有高达64类计数矩阵同时计算。给每个测试站专配一个µ-MUSYCS测量系统以符合规范。为此软件有专门编写的对话使矩阵以及计数过程参数化。


结果矩阵，反过来，根据雨流（能级分布水平——LDC）或其他计数程序提供基本信息。除了这些数据，还包含使用过的齿轮和被选择的应力分布，因为不同齿轮和不同应力分布导致这不同矩阵的集合。

　　　 

像正在使用的齿轮等信息直接从测试站控制系统或者，不可以的话，齿轮信息也能直接从齿轮箱的传入／传出RPM比中分离出来。所有这些计算必须在线显示，这样，“直播”的数据监视曲线让FORD工程师看到试验进程。基于imc报告生成器的实时报告很容易完成。结果自动存储在数据库；离线数据评估可用FAMOS，即imc的离线数据评价软件。


最后，整个测试系统可用于一个分离的、独立模式，或可完全受控于测试台控制系统。这样，连续数周甚至数月的长期测试可在无人值守下进行。
