Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] The invention provides a weighing method. figure 2 is a flow chart of a weighing method according to an embodiment of the present invention, such as figure 2 As shown, the following steps S202 to S206 are included.

[0021] Step S202, determining the division value in the calibration data according to the estimated weight of the item to be weighed and the weighing range of the scale.

[0022] Step S204, calculating scale calibration data parameters according to the division value.

[0023] Step S206, calculating the weight value of the item to be weighed according to the scale calibration data parameters.

[0024] In the related art, it is necessary to repeatedly calibrate the scale during the process of weighing items, which results in time-consuming and labor-intensive implementation. In the embodiment of the present i...

Abstract

The invention discloses a method, a device, a system, a lower computer and a stirring station for weighing. The method includes the steps of determining a division value in scale calibration data according to the estimated weight of a to-be-weighed article and a weighing range of a scale; calculating scale calibration data parameter according to the division value; and calculating the weight value of the to-be-weighed article according to the scale calibration data parameter. The method disclosed by the invention can avoid repeated scale calibration during the weighing process of the article, is time-saving and labor-saving, and can improve the measuring accuracy of the scale as much as possible on the premise of satisfying the metering range.

Description

technical field [0001] The invention relates to the field of machinery, and more specifically, to a weighing method, device, system, lower computer and mixing station. Background technique [0002] At present, the weighing system of the mixing plant control system usually consists of an upper industrial computer, a lower computer, a pressure sensor, a weighing transmitter and a weighing bucket. The weighing process is as follows: the pressure sensor sends the voltage signal of the weight of the material weighed by the weighing hopper to the weighing transmitter, the voltage signal is amplified through the weighing transmitter, and the lower computer passes the voltage signal through the analog digital (Analog Digital, referred to as The conversion of the AD) module becomes the corresponding digital quantity, and then converted into the corresponding weight value through the calibration data algorithm, and then returned to the host computer for display. [0003] Due to the l...
