The invention relates to a remote-control digital weighing
machine with a temperature compensation function and a temperature compensation method for the remote-control digital weighing
machine. The remote-control digital weighing
machine comprises a weighing sensor, an AD (analog and digital) conversion module, a CPU (
central processing unit), an external DSP (
digital signal processing) display, an interface circuit, a temperature compensation circuit, an external
voltage testing circuit, a keyboard circuit, a
wireless communication module, a power supply and a DC-DC
charge pump of a stabilized
voltage supply; an equal-arm bridge of the weighing sensor comprises four resistance strain gauges, and various components are powered by the power supply and the DC-DC
charge pump of the stabilized
voltage supply; after force signals detected by the weighing sensor are converted into analog electric signals, the analog electric signals are inputted into the AD conversion module and are converted into digital signals, and the digital signals are inputted into the CPU to be processed, so that a
weight value of a measured object is obtained; output ends of the CPU are respectively connected with the external DSP display and the interface circuit, an input end of the CPU is connected with the temperature compensation circuit, and another output end of the CPU is connected with the
wireless communication module; the power supply outputs two power supply channels via the DC-DC
charge pump of the stabilized voltage supply, and the AD conversion module and the CPU are respectively powered by the two power supply channels. The remote-control digital weighing machine and the temperature compensation method can be applied to different service places.
