MULTI-CHANNEL DEVICE FOR DATA COLLECTION WITH ACCELEROMETERS Russian patent published in 2018 - IPC G01M1/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to devices for converting analog signals into a digital representation and can be used in equipment for collecting and processing vibration signals from vibration sensors, in particular accelerometers. For this purpose, a multi-channel device for data acquisition from accelerometers contains groups of channels 1 and 2, in each group of channels in each channel it contains matching amplifiers 3 which inputs are connected to the inputs of respective integrating nodes 5, output of each integrating unit 5 is connected to a first input of corresponding analog switch 6, output of which is connected to an input of corresponding low-pass filter 7 which output is connected to a corresponding input of analog-to-digital conversion node 9 of the corresponding group of channels, second input of analog switch 6 of each channel of this group of channels is connected to an output of matching amplifier 3 of the same channel of another group of channels.

EFFECT: technical result is the expansion of functional capabilities on the basis of improved control and fault tolerance.
