MULTICHANNEL DEVICE FOR DATA COLLECTION FROM ACCELEROMETERS Russian patent published in 2018 - IPC G01M7/02 

FIELD: microelectronics.

SUBSTANCE: invention refers to the devices for converting analog signals into their digital representation and can be used in equipment for the collection and processing of vibration signals from the vibration sensors, in particular from accelerometers, for solving the problems of vibration diagnostics and protection of equipment for exceeding the permissible level of vibration. Multichannel data acquisition device with accelerometers contains the first and second matching amplifiers in each pair of channels, the inputs of which are the inputs of the odd and even channels, the outputs of the first and second matching amplifier are connected to the inputs of the first and second integrating units, respectively, the output of the first integrating unit is connected to the first input of the first analog switch, the output of which is connected to the input of the first low-pass filter, the output of which is connected to the odd input of the analog-to-digital conversion unit, the output of which is the output of the multichannel data acquisition device that gather data from accelerometers, the even input of the analogue and digital unit is connected to the output of the second low-pass filter, and the control outputs of the analog and digital conversion unit are connected to the control inputs of the first and second analog switches, the output and the first input of the second analog switch are connected to the input of the second low-pass filter and the output of the second integrating unit respectively, and the second inputs of the first and second analog switches are connected to the outputs of the second and first matching amplifiers.

EFFECT: technical result during the implementation of the claimed invention is the increase in controllability, fault tolerance and expansion of functionality.
