Problems solved by technology

The realization of this method is not based on the function of the excavator itself, but an additional adjustment system used by mine users, which is of little value to excavator manufacturers
Moreover, the high cost of the card adjustment system itself also limits its scope of application, and many open-pit mine users are still using manual production counting
[0003] It needs to be explained that some foreign excavators also have the function of output counting, but because the statistical model is too simple and rough, the counting is not accurate, so it is rarely used in practice

Embodiment Construction

[0010] The principle of the real-time production statistics of the excavator of the present invention will be described in detail below.

[0011] In the working process of the existing excavator, there are corresponding control actions for various actions of the excavator, and these control actions have corresponding state parameters corresponding to the specific addresses of the electrical control core PLC. Carry out real-time comprehensive analysis of several existing state parameters of the excavator to judge whether it is loading at a certain moment. If it is loading, the output statistical value will increase by 1. These parameters can be directly or directly from the specific address of the electrical control core PLC. Indirect acquisition does not require the introduction of additional hardware devices.

[0012] First of all, the excavator can only be loaded when the bucket is opened, so this method judges the variable based on the logical quantity of bucket opening, an...

Abstract

The invention discloses a static method of output of a mining excavator, which comprises the following steps of: collecting a bucket starting logical quantity signal of a bucket of the excavator, and judging whether to start the bucket according to the bucket starting logical quantity signal of the excavator; collecting rotation angle parameter information of the excavator, and judging whether rotation of the excavator exceeds a specified threshold value according to the rotation angle parameter of the excavator; collecting a height parameter of the bucket of the excavator, judging whether the height of the bucket exceeds the height of a truck according to the height parameter, and judging whether the excavator is loaded according to the judging result about height; and if both the judging results are yes, judging that the excavator is loaded once, and with the ending of the judging about loading work of each time, adding one to a statistic value of the output; and if any one of the judging results is no, judging that the excavator is not loaded.

Description

technical field [0001] The invention relates to a method capable of automatically performing real-time output statistics on large open-pit mining excavators. Background technique [0002] The output statistics of excavators are very important to users, and they are the basic data for calculating economic benefits and workload of production personnel. Domestic and foreign mining excavators do not have a structure directly related to the excavation work of the equipment, nor do they have this function attached. At present, the output counting of mining excavators is still using the manual counting method to count the output, and some additionally introduce expensive truck dispatching systems to replace manual labor. Among them, the card adjustment system statistics method requires installing GPS on the excavator and the matching ore transport truck respectively, and counts by judging the running route of the truck, that is, the number of round trips between the excavation sit...
