具有称重功能的便携式电子装置及电子秤系统
摘要：
一种具有称重功能的便携式电子装置，包括壳体、压力传感器、信号处理模块、模数转换模块以及中央处理器，所述壳体用于承载被称重的物体；所述压力传感器用于产生并输出与其所受压力相对应的模拟电压信号；所述信号处理模块用于对所述压力传感器输出的模拟电压信号进行滤波及放大；所述模数转换模块用于将信号处理模块处理后的模拟电压信号转换为对应的数字电压信号；所述中央处理器用于根据所述数字电压信号计算所述压力传感器所承受的重量值，并在称量所述物体前，将计算出的多个压力传感器所承受的重量值设置为所述便携式电子装置称重时的称重零点，以对所述便携式电子装置进行去皮。本发明还涉及一种电子秤系统。
摘要（英）：

A portable electronic device having a weighing function comprises a shell body, pressure sensors, a signal processing module, an analog-digital conversion module and a central processor, wherein the shell body is used for bearing a weighed object; the pressure sensors are used for producing and outputting analog voltage signals corresponding to pressure on the pressure sensors; the signal processing module is used for filtering and amplifying the analog voltage signals output by the pressure sensors; the analog-digital conversion module is used for converting the analog voltage signals processed through the signal processing module to corresponding digital voltage signals; the central processor is used for calculating the value of the weight borne by the pressure sensors according to the digital voltage signals and setting the value of the weight borne by the pressure sensors to the weighing zero point when the portable electronic device carries out weighing before the object is weight to shell the portable electronic device. The invention further relates to an electronic scale system.
