MHz series data acquisition system
imcAccess Co Ltd
The requirements for modernization testing are constantly increasing. In addition to obtaining pure physical quantities such as pressure, temperature and voltage, it is necessary to obtain fast signals from sensors, such as collecting and recording signals from electronic control units in new-energy vehicles. This is a new measurement concept that simultaneously collects ‘slow’ and ‘fast’ data.
Multi-channel simultaneous measurement of different physical quantities is a common vehicle component test task. Under normal circumstances, the sampling frequency of a comprehensive measurement system is sufficient if it reaches a single channel of 100kHz. However, to measure the voltage signal of the electronic control from the circuit, ignition or injection process, a measurement system in the MHz range is needed. In traditional experiments, oscilloscopes are often used to capture high-speed signals; however, other data cannot be recorded and the data cannot be correlated with each other. The new imc EOS makes up for the lack of parallel acquisition between high- and low-speed signals in the dynamic test process and enables these signals to be linked to each other.
The imc EOS four-channel isolated precision measurement system can measure fast dynamic processes. Equipped with BNC or LEMO interface, it measures and records current, voltage, vibration, sound and high-frequency signals during explosion and ignition with 1.7MHz bandwidth and 4MHz high sampling frequency to ensure high-quality signal collection.
The structure of imc EOS is compatible with the imc CRFX series and can be combined flexibly through buckles. Multiple EOS modules buckle stack, or combine, imc NET-SWITCH (network switch) to achieve synchronization and system networking. The system can be operated independently and connected to the internet. The maximum capacity of local storage is 1TB.
imc EOS is particularly suitable for fast processes in material testing, component testing and vibration analysis. In the automotive field, imc EOS can study processes during fuel injection and ignition, record high-frequency vibrations in the engine, transmission and chassis, and analyze the speed change process of the control unit. In the electric-vehicle area, it can be used for research on motors controlled by inverters, etc.
The imc EOS operating options will soon be expanded through the app. Users will be able to start and stop measurements directly from a smartphone or tablet, or trigger and view data in real time.
