Embodiment Construction
[0076] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0077] The weighing data processing method of the scale that the embodiment of the present invention provides can be applicable to such as figure 1 In the system architecture shown, the system architecture includes a load cell 100 , an analog-to-digital conversion device 200 , a central controller 300 and a weighing actuator 400 .
[0078] Specifically, the load cell 100 deforms its resistance stress sheet after receiving the pressure from the scale body, and the load cell 100 converts the resistance change into a voltage signal for output.
[0079] The analog-to-digital conversion device 200 converts the voltage signal output by the load cell 100 into a digital sign...

The invention discloses a weighing data processing method and device of a scale, and a storage medium. The method comprises steps of obtaining the measurement weighing data of a current moment, the prediction weighing data of the current moment and a filtering parameter, and determining a gain coefficient of the current moment according to the filtering parameter, and performing weighted summation on the measured weighing data at the current moment and the predicted weighing data at the current moment according to the gain coefficient at the current moment to obtain filtered weighing data at the current moment, and determining weighing result data at the current moment according to the filtered weighing data at the current moment. According to the method, the measured weighing data at the current moment and the predicted weighing data at the current moment are weighted through the gain coefficient at the current moment, so vibration interference is eliminated, a phenomenon of large peak fluctuation represented by discrete data is avoided, and accuracy of weighing result data is improved.
Description
technical field [0001] The invention relates to the field of weighing technology, in particular to a weighing data processing method, device and storage medium. Background technique [0002] Non-linear random disturbances such as the vibration of the scale body, the response speed of the drive mechanism, and the unevenness of the material itself will cause the collected weighing data to reflect a discrete distribution. [0003] Based on this, the current weighing data processing methods are mostly limit filtering, median filtering, arithmetic mean filtering, etc. These methods cannot effectively eliminate the occasional fluctuation of data, resulting in large weighing errors. [0004] To sum up, there is an urgent need for a weighing data processing technology to solve the above-mentioned problems in the prior art. Contents of the invention [0005] Due to the above-mentioned problems in the existing method, the present invention proposes a weighing data processing method...
