Management system for managing bulk material inside a silo using a set of load cells and an accelerometer

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).
