WEIGHT OF MATERIAL UNLOADED BY LIFTING MECHANISM MEASURING AND MONITORING SYSTEM Russian patent published in 2017 - IPC G01G19/18 B66C13/16 

FIELD: measuring equipment.

SUBSTANCE: invention relates to weight measurement equipment, in particular, to lifted loads weighing devices, for example, mineral mines skip hoists. Disclosed shipped material measurement and weight control system by lifting mechanism contains, at least, two communication devices, each of which consists of radio modem, Ethernet switch, power supply source. At that, one of communication devices is installed in close proximity to point of skip loading with material, second device is from skip unloading point. Communication devices transmit obtained measurements data over wire communication lines to programmable logic controller, installed in control cabinet. Besides, system also includes data collection station, consisting of radio modem, operating in half-duplex mode, strain transducer, power supply source. Data collection station is installed on skip roof for collection, processing and conversion of signals into digital code for subsequent transmission over radio channel. Skip ropes tension measuring sensors serve for loaded into skip material weight measurement. Upper level sensor, which is connected to data collection station, is installed in skip wall taking into account of maximum filling level, to prevent loaded material transfer into skip.

EFFECT: technical result is increase in produced material weight measuring accuracy, controlling material production process, higher safety of operating personnel at material loading, as well as devices error determination, intended for material weight measurement.
