Patent ID: 8581734

Claim:
A management system for managing bulk material inside a silo, characterized in that it comprises: A set of load cells ( 16 ) screwed onto supports ( 35 ) that are welded to the legs of the silo and the tension of which can be controlled by tightening or loosening a screw ( 31 ); Electronic equipment ( 17 ) which measures the tension in the cells, calculates the weight of the material in the silo and transmits it via radio towards a communication gateway ( 25 ) which links it to the Internet; A photovoltaic solar panel which supplies the system with solar energy and eliminates the power supply from the equipment to the electric network; A set of supercaps which store electric energy allowing the system to operate in periods where light is absent and prevents using batteries that may deteriorate over time; An accelerometer which allows measuring if the silo is moved and its inclination; a thermistor ( 48 ) with signal adaptation towards an analog input of the microprocessor ( 39 ) so that the electronic equipment can measure the room temperature and perform temperature compensation calculations in the measurement of the load cells; a real-time clock which allows the microprocessor ( 39 ) to measures lapses of time and record events with date, hour, minutes and seconds; a serial communication channel with a conversion stage via radio ( 45 ) which allows the system to communicate with other external devices; an electronic unit ( 44 ) for managing the energy which rations the use of this energy and allows prolonging the duration of the energy stored in the supercaps ( 19 ).
