[0002] In order to ensure the quality of tobacco leaves, the method of baking is usually adopted to control the moisture, color and aroma of tobacco leaves. When baking tobacco leaves, the degree of baking is usually controlled by observing the weight. The traditional weighing of tobacco leaves usually adopts the static weighing method, and the tobacco leaves are weighed after baking in the baking house. This method requires manual operation, which not only has low efficiency, but also is prone to human error. In addition, since the weighing process occurs after baking is completed, it is impossible to monitor the weight change of tobacco leaves in real time, so it is difficult to accurately master the moisture evaporation and quality change during the tobacco leaf processing process, affecting the quality control of tobacco leaves.

However, during the weighing process, the weighing sensors used in the system may not have high enough accuracy, resulting in inaccurate weighing results, data transmission may be unstable, affecting the integrity and timeliness of data, and the user interface design is not friendly enough, making it difficult for non-professionals to operate. Therefore, the number of poles and weight data of tobacco leaves are missing, resulting in problems such as extended baking time and inaccurate tobacco leaf yield measurement.
