Abstract

The invention discloses a weighing system, a weighing method and a storage medium, wherein the weighing system comprises weighing sensors arranged in a scale body and a control instrument in communication connection with each weighing sensor; when the control instrument detects that a failure sensor exists in the weighing sensors, based on parameter information of the failure sensor, a preset weight distribution coefficient of the weighing sensor and a weight output value of the weighing sensor with normal state in the weighing sensors, and the weight value of the whole scale is calculated andgenerated. According to the invention, through the self-learning of the weighing data of the weighing system, under the condition that the fault weighing sensor is not replaced, the continuous weighing is achieved, and higher weighing precision is maintained, so that the loss caused by the fault of the weighing sensor or the failure of timely replacement of the weighing sensor is avoided.

Description

technical field [0001] The present invention relates to a weighing system and method and a storage medium, especially a digital weighing system and method and a storage medium. Background technique [0002] At present, the digital weighing system is composed of weighing components such as digital weighing sensors, digital weighing display control instruments, weighing tables and communication cables. Among them, the digital weighing sensor and the digital weighing display control instrument form a digital communication network. [0003] After the weighing system has been calibrated and used for a period of time, if the weighing performance of some digital load cells fails, such as a communication failure of the load cell, the temperature detected by the temperature detection module inside the load cell exceeds the absolute working temperature of the sensor range or the actual on-site working temperature, the load cell is overloaded, the zero point is out of tolerance, etc.,...
