Smart Dynamic Weighing System

The article considers the method of weighing by measuring the generator frequency, which depends on the parameters of resistance strain gages, located in checkpoints across the researchable object area or site and connected to external capacitors of a phasing RC circuit in conjunction with an amplifier forming a generator, the average signal of which is fed to a microcontroller via a functional frequency-to-code converter. The influence of the ambient temperature, as well as the load on the output frequency of a generator with a phasing chain of strain gauges of a mass measuring device, is studied. The form of the conversion function recording is obtained, which is convenient for studying the influence of simultaneous changes in the parameters of several load cells or the sensitivity with respect to many elements that affect the change in the frequency of the generator. The data processed is displayed in the units of mass considering the ambient temperature. A block diagram of a continuous dynamic weighing technique, using standard strain gages with averaging readings without additional computing devices, has been proposed.
