STRAIN-GAUGE SYSTEM FOR DETERMINING THE STRAIN IN THE GROUND Russian patent published in 2019 - IPC G01R19/252 G01R19/25 

FIELD: measuring equipment.

SUBSTANCE: invention relates to electronic measuring equipment, in particular, devices for converting the field of the analog signal of strain gauges into digital codes, it controls and records the main test parameters and can be used as part of signal processing systems measuring voltages in the ground. Technical problem solved by the invention is to simplify the design of the device, reducing its energy intensity and miniaturization performance. Proposed system contains a strain-gauge module, block of tuning switches, electronic computer, microprocessor strain gauge station, including built-in measuring amplifiers, microcontroller, multichannel analog-to-digital converter, discrete input port, power supply, universal asynchronous transceiver connected via an interface converter to a personal electronic computer. Strain-gauge module is connected to the measuring amplifiers via a connector and connected to a multichannel analog-to-digital converter with the ability to connect up to 256 sensors, and the set of setting switches is connected via a connector to the discrete input port.

EFFECT: technical result obtained by using the invention is to improve the operating characteristics, to reduce the size of the device, to reduce power consumption, to increase speed and to increase the number of measured parameters.
