Problems solved by technology

[0004] However, the new non-contact measurement method generally has the disadvantages of high requirements on environmental parameters and high investment costs, and generally does not have networking and networking functions, and cannot be applied to real-time measurement and analysis of multiple stockpile volumes

Embodiment Construction

[0025] Measuring principle: The measuring mechanism divides the entire bulk material into many small cylinders with the same bottom area, and uses ultrasonic ranging technology to measure the height of each cylinder. According to the divided small cylinder specifications, each small cylinder can be determined in advance The volume of this small cylinder can be calculated, and then the volume of all small cylinders can be accumulated to obtain the volume of the entire stockpile. Therefore, the determination of the bottom area of ​​the small cylinder and the height measurement of the small cylinder become the key points of the measurement. In general, large-scale bulk materials are equipped with portal stacker reclaimers or gantry cranes, whose width generally just crosses the stockpile, and a full-stroke movement also just covers the length of the stockpile, so the portal stacker reclaimer Ultrasonic ranging modules are installed on the beam at an interval of w, and the portal ...

Abstract

The invention provides a volume measuring device for large bulk stockpiles and a method thereof. The device comprises a measuring device, a measuring computer, and a communication network that is connected with the measuring device and the measuring computer, wherein the measuring device comprises a high-speed singlechip, a portal stacking / reclaiming device, a distance measuring sensor array, a data collecting module, a communication module and a motion control module, wherein the distance measuring sensor array is arranged on a crossbeam of the portal stacking / reclaiming device; and the data collecting module, the communication module and the motion control module are connected with the high-speed singlechip. In the measuring process, the method comprises the steps of firstly setting the spacing parameter and quantity of the distance measuring modules, and the stepping values of the portal stacking / reclaiming machine; subsequently measuring the instructions emitted by the computer; leading the portable stacking / reclaiming machine to advance to the starting position at one end of the stockpiles; scanning the measuring values of each distance measuring module by the singlechip so as to complete scanning data sampling; and finally transmitting the collected data set to the measuring computer by the singlechip; and after receiving the measuring data set by the measuring computer, carrying out the measuring and calculating task and the three-dimension chart drawing tasks. The measuring device is simple, the measuring precision is high, and the measuring device can work reliably for a long time.

Description

technical field [0001] The invention relates to a measuring device, in particular to a volume measuring device for large bulk materials. Background technique [0002] Accurately measuring the volume of large irregular bulk materials has been a technical challenge for many years. For a long time, the measurement of the volume (mass) of bulk materials in China has generally been carried out by manual measuring scales. Its basic working method is to first shape the bulk materials, and then measure the basic geometric parameters such as length, width and height of the regular stockpile with a ruler, and then calculate the volume of the stockpile. However, in this process, due to the need to manually reshape the stockpile, and the reshaping is often not very accurate, the horizontal plane is inclined, and the surface of the scattered materials is uneven. Using a ruler to measure is likely to cause deviations from the actual volume, which directly affects the unit. The accurate ...
