Multi-module weighing method and system

Abstract

The invention discloses a multi-module weighing method and system. According to the method, a host time module is added in a weighing host, an extension time module is added in each weighing extension, the concept of timestamps is introduced, when the weighing host works, a control instruction is sent to generate a host timestamp, each weighing extension completes measurement and weighing and generates an extension timestamp, when the weighing host calculates the weight, the host timestamp and measurement result data of each weighing extension corresponding to each extension timestamp are adopted to change the original dynamic measurement result data of each weighing extension into static measurement result data so as to ensure the synchronism and consistency of data sending and receiving,reduce the data fluctuation and effectively improve the measurement accuracy; and moreover, communication is performed based on an LORA chip, energy consumption can be effectively reduced, the measurement accuracy can be effectively improved by additionally arranging the host time module and the extension time module, the system hardware structure is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of weighing equipment, in particular to a multi-module weighing method and system. Background technique [0002] A multi-module weighing system refers to a weighing system composed of a weighing main unit and more than two weighing sub-machines. During measurement, due to the shaking of the measured object, the measurement result data of each weighing sub-machine is a dynamic value. When the weighing host calculates the weight, the measurement result data used cannot be guaranteed to be the measurement result data of each weighing extension at the same time point. Due to the asynchronous nature of receiving and sending data, there are errors in the measurement results. This error is often Large fluctuations lead to inaccurate measurement results. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a multi-module weighing method and system capab...
