Overview
The mine mineral loading and collection system is a set of barcode solutions adopted by coal mine enterprises in the production and loading links in order to increase the speed of mining and production mobile operations, manage the mining operation site in real time, and achieve the target requirements of barcode wireless data management.
This proposal was proposed by Shenzhen Jiu Rui Technology Co., Ltd. (the author).
User needs
In the process of coal mine production and mining operations, it is necessary to manage the minerals that are excavated and loaded every day with barcodes, and to scan the barcodes of the minerals loaded on each truck. Using the wireless WIFI system, the barcode of each mineral truck is transmitted to the database of the ground office in real time. And the loading status of the mining operation site can be checked at any time from the database, such as the number of vehicles loaded per day, the date of each loading, etc. At present, because there is no wireless transmission system, barcode acquisition system and related management software in the mine, the ground manager cannot know the real-time operation situation in the mine.
The following is the current situation of the customer:
A: A stable and reliable wireless transmission equipment and system are required. It can transmit the data collected by the bar code in the mine in real time. .
B: Need some bar code collection equipment, which can work stably and reliably in the mine environment. And collect barcodes.
C: Relevant software is needed to coordinate the bar code collection and wirelessly transmit it to the ground office database. The computer in the office can receive, manage, and query the data of the on-site vehicle loading in the mine at any time.
Problems that customers need to solve when applying mine wireless data acquisition and transmission systems:
In view of the above-mentioned on-site situation, it is now necessary to use wireless barcodes to solve the situation of loading vehicles in the well, and do two things:
1. Ensure that all loading data is collected in real time and uploaded to the ground office.
2, to ensure that the management software in the office can receive and manage the data sent from the underground at any time.
System function solution
According to the above user needs, the company proposes the following solutions, which are divided into system platform solutions, hardware selection solutions and software development solutions.
The system platform scheme is the overall principle architecture of the system and the theoretical basis for the other two schemes; the hardware selection scheme provides the material basis for the system to realize the system platform and meet the needs of users, and the software development scheme is a solution to user needs directly plan
These three levels of programs together constitute a solution to the requirements described in the previous section.
System platform solution
For the system solution, the user requirements can achieve the following points:
It is hoped that the management of underground mining operations can be realized through the management of bar codes.
It is hoped that the operation speed is fast and the loading situation can be managed in real time.
It can wirelessly transmit the collected bar code data in real time.
Scanning and statistical data can be inquired from the ground office.
In the mine site, each bar code collection point needs to use a wireless bar code collector.
According to the above customer needs and requirements, the following system platform architecture is recommended:
A computer is deployed in the ground office to complete the functions of receiving, storing, querying and managing collected data.
About 3 wireless APs and signal amplification antennas are deployed in the mine to form a wireless data transmission system.
Deploy a wireless barcode collection device at the mine mining and loading operation site.
The system hardware and platform of the above scheme are shown in the figure below:
Software development plan
Our company will customize and develop application software for users. The on-site business support system on the data acquisition computer should meet the needs of on-site business, various operations and provide man-machine interface design suitable for industrial on-site operations.
Complete basic on-site verification, and give necessary prompts for collection errors and missed omissions.
Development environment
This system will be based on the Microsoft .NET architecture and C# as the development language. A set of on-site collection system based on the .NET architecture will be customized on the computer side for users to realize the mineral loading collection user interface and support users in the business process. Data collection, and provide data query, storage and verification on site.
On-site collection process:
Establish the data mapping relationship of “loading collection-product” through the bar code data collection system.
The entire software data workflow is as follows:
Wireless barcode collection program——“Wireless upload——–“Webservice middleware——-? Ground office database “————- Office PC application
A total of 3 sets of software are required to complete the above program: 1. Wireless barcode collection program (terminal). 2. Webservice middleware. 3. PC-side database management application software.
1 The wireless barcode acquisition program (terminal) completes the following functions:
Collecting loading information in the well: The mining operation workers in the mine use the wireless bar code collection terminal to scan the bar code on the car after loading each car of minerals, and record the date and time of the on-site bar code collection.
Wireless real-time transmission: After each loading data is collected, you can press the send button. The data is immediately transmitted wirelessly to the computer database of the ground office.
2. Webservice middleware completes the following functions:
Facts receive bar code data and import it into the database: Realize to receive data from the mine and write it into the ground office database.
3. Office PC application
Database statistics query management: From the application program of the ground office, you can manage and query the barcode data and other related information uploaded from the well at any time.
Software function description
The on-site collection and scanning software of mineral loading in the well has the functions of bar code identification, real-time data collection and wireless upload:
1. Barcode recognition and reading
Can read all one-dimensional bar codes as required.
2. Real-time data collection
Collect data such as barcode and time and date of loading in the well and upload it wirelessly in real time.
3. Result statistics and query
The computer database of the ground office has statistics, query and real-time management of the data uploaded from the well.
