Automatic wharf material metering method

Abstract

The invention discloses an automatic wharf material metering method. A material weighing system meters a first weighing hopper and the first-time tare of the first weighing hopper; if a first weighing device begins distributing materials, after the first weighing device finishes distributing the materials, the rough weight and the tare of the first weighing hopper are automatically metered; the tare of the first weighing hopper this time is subtracted from the rough weight of the first weighing hopper this time to obtain the net weight of the materials in the first weighing hopper this time; after metering of the first weighing device is finished, the rough weight and the tare of a second weighing hopper are metered, the two steps are alternated repeatedly in this way, and the net weight of the materials in the first weighing hopper and the materials in the second weighing hopper are accumulated each time to obtain the net weight sum; according to the material weighing system, the first-time tare of the first weighing hopper and the first-time tare of the second weighing hopper are subtracted from the sum of the net weight sum of the materials in the first weighing hopper and the materials in the second weighing hopper and the last-time tare of the first weighing hopper and the last-time tare of the second weighing hopper to obtain the total weight of the materials in a ship. According to the automatic wharf material metering method, the metering accuracy of wharf metering is improved, and the work intensity of metering personnel is greatly relieved.

Description

technical field [0001] The invention relates to a method for measuring bulk raw materials at a wharf, in particular to an automatic measurement method for materials at a wharf. Background technique [0002] At present, due to the increase in production capacity, some large domestic enterprises need to purchase a large amount of ore, iron ore, coal, pellets, limestone and other raw materials, and these bulk raw materials are mainly transported by ship. These bulk raw materials are weighed by the measurement method of checking the ruler and looking at the waterline. This method mainly uses human eyes to observe the water level of the hull for measurement. The numbers often have errors, and the hull is huge, so a small error in observing the water level will also lead to a huge difference in the measurement results, which leads to illegal acts such as fraud and increases the production cost of the buyer or seller. Moreover, the measurement data of the terminal is manually inpu...

These bulk raw materials are weighed by the measurement method of checking the ruler and looking at the waterline. This method mainly uses human eyes to observe the water level of the hull for measurement. The numbers often have errors, and the hull is huge, so a small error in observing the water level will also lead to a huge difference in the measurement results, which leads to illegal acts such as fraud and increases the production cost of the buyer or seller

Moreover, the measurement data of the wharf is manually input into the computer for later statistics and calculations. This method requires a lot of human resources, and the work intensity of the measurement staff is high.

Therefore, this measurement method has many disadvantages.
