Abstract

The invention provides a weighing method and a weighing system. An instrument communicates with at least one sensor, the instrument and the sensor make backups of core parameters for each other, the sensor has a first core parameter, and the instrument has a second core parameter. The weighing method at an instrument end comprises the following steps: initializing the instrument, and according to a judgment, selecting whether to carry out group weighing and calibration processing on a weighing platform; making a backup of the first core parameter, including determining whether the instrument stores a third core parameter which is a core parameter of a sensor previously communicating with the instrument, if the instrument stores the third core parameter, updating the third core parameter according to the first core parameter, and if the instrument does not store the third core parameter, storing the first core parameter as the third core parameter in the instrument; and carrying out weighing processing. The sensor also makes a backup of the second core parameter. According to the invention, dual mutual backup of the core parameters is realized.

Description

technical field [0001] The invention relates to the weighing field, in particular to a weighing method and a weighing system. Background technique [0002] At present, the digital weighing system is composed of a number of digital weighing sensors, digital weighing display control instruments, weighing tables and communication cables. The digital load cell saves the core parameters of the sensor itself, such as compensation calibration, filtering, production process, and factory settings. The factory settings include the zero point, capacity, output unit, full scale, accuracy level, product model, and temperature of each sensor. , diagnostic records and other important data, the digital weighing display control instrument saves the weighing range of the weighing platform, the weighing display unit, the weighing display resolution, clearing and tare, the list of connected digital sensors, and the zero point of the weighing platform And core parameters such as range calibrati...
