Digital weighing sensor and sensor network

Abstract

The invention relates to a digital weighing sensor comprising a force measuring element, a power supply excitation module, a signal detection module, a microprocessor, a communication module, a line current control module, and a configuration control module. The signal detection module can be used for signal conversion by first configuration control information by adopting a corresponding detection mode. The processor can be operated by second configuration control information by adopting one or a plurality of inner core / s or processor / s. The communication module can be used for communication by third configuration control information by adopting corresponding communication protocol, terminal matching, and impedance control. The line current control module can be used for configuration of the switching on / off, the voltage value, and the current value of the power supply excitation module, the signal detection module, the microprocessor, and the communication module according to fourth configuration control information. The configuration control module can be used to transmit the first configuration control information, the second configuration control information, the third configuration control information, and the fourth configuration control information according to the selected working mode. The invention also provides a digital weighing sensor intelligent network based on the multi-configuration technology.

Description

technical field [0001] The present invention relates to a weighing system, in particular to digital weighing sensors and sensor networks. Background technique [0002] In the modern industrial production process, the weight information provided by the weighing system is the key information source and control target. With the development of digitization and information technology, the traditional weighing system has begun to enter the era of digital weighing system. Specifically, a circuit with high-precision analog-to-digital conversion and digital processing capabilities is built into the sensor to convert the load-bearing information of the sensor into a digital signal. One or more digital weighing sensors exchange data and instructions with terminal equipment such as instruments and industrial computers through wired or wireless communication methods, and together constitute a weighing communication topology network. The digital load cell sends the formatted weighing da...
