DEVICE FOR DATA COLLECTION Russian patent published in 2018 - IPC G06F17/40 

FIELD: radio engineering, communication.

SUBSTANCE: device comprises of a signal shaping input circuit, including a current sensor and a differential amplifier, an analogue-to-digital converter, a sensor power supply, n-signal shaping input circuits, a pilot signal shaping unit, a switch, a signal conditioning unit, wherein each of the n-signal shaping input circuits includes a current sensor coupled to a differential amplifier, the inputs of the n-signal shaping input circuits are connected to the output of the pilot signal shaping unit, and the outputs are connected to the inputs of the switch, which is connected to the input of the signal conditioning unit connected to the input of the analogue-to-digital converter. The switch has an input for receiving the first testing voltage and a control input that is the first control input of the device. The pilot signal shaping unit has an input for receiving the second testing voltage and a control input, which is connected to the sensor power supply control input, which is the second control input of the device.

EFFECT: providing integrated control of the elements of the proposed device, which leads to a reduction in maintenance time.
