Self-learning dynamic weighing method for high-speed pick-up

Abstract

The invention discloses a self-learning dynamic weighing method for high-speed bulky cargos. The method comprises the steps that firstly, three photoelectric switches are arranged on an adhesive tape machine at a weighing section, wherein the first photoelectric switch is arranged at the front end, the second photoelectric switch is arranged at the midpoint, and the third photoelectric switch is arranged at the tail end; secondly, a front photoelectric switch is arranged on a previous adhesive tape machine in front of the adhesive tape machine at the weighing section, the distance between the front photoelectric switch and the first photoelectric switch is slightly larger than a package maximum length allowable value of a double-package weighing method, and a control system is used for controlling a weighing module to weigh packages during one weighing cycle, wherein two conditions exist during one weighing cycle; when the lengths of two packages are continuously within the range of the package maximum length allowable value of the double-package weighing method, and the front photoelectric switch is used for controlling the distance between two packages to be measured to meet the conditions, weighing is conducted through the double-package weighing method; otherwise, weighing is conducted through a single-package weighing method; when one weighing cycle is over, the packages moving forwards continuously are weighed by repeating the steps until all the packages are weighed. By the adoption of the method, the weighing efficiency of the bulky cargos can be substantially improved.

Description

technical field [0001] The invention relates to the field of postal express delivery, and more specifically relates to a self-learning dynamic weighing method for high-speed pick-up. Background technique [0002] Generally speaking, bubble goods are light goods. In the express logistics industry, it is generally defined as bubble goods when the volume / 0.006 is greater than the weight. [0003] Existing methods for weighing goods in the express delivery industry are all based on certain hardware with dynamic weighing functions. During the weighing process, the weighing is triggered by an external signal (such as a sensor), and after the weighing calculation is completed by a certain algorithm, the weighing action is terminated by an external signal (such as a sensor), so that the next item of goods can enter the weighing section Repeat the above operation. [0004] The current technical solution basically designs the weighing section around the action of weighing one and on...

Problems solved by technology

[0021] When the bottom surface of the package is uneven, the package does not have a stable level but has multiple rising and falling sides when the package passes through the photoelectric. exact weight of a package" and shut down

When there is only one package passing the weighing section at the same time, the continuous level can be forcibly merged into one level in the software, because in the physical logic of the machine, there is no situation in which two packages are continuously loaded on the machine, but at the same time there are When multiple packages pass through the weighing section, there must be a chance that two packages will go on the machine consecutively. Therefore, when the bottom of the package is uneven, the existing solution will weigh one package as two packages, but cannot find the last package. The signal of leaving the weighing section, so the alarm stops

[0022] In order to avoid the occurrence of situation 1, in some schemes, the vertical installation position of the trigger photoelectric will be increased, so that the problem of uneven bottom surface can be avoided with a high probability, but at the same time, the problem of signal loss for packages with lower heights will arise

When the height of a package is low (envelopes, documents), the package cannot trigger the photoelectric after passing the weighing section, so the weighing information will be lost
