Design And Implementation Of The System Aimed At Track Scale Measuring And Process Based On Distribution Environment

With the rapid development of IT and its widely appliance, the Chinese enterprises are undergoing a fundamental revolution in profit and management. In order to catch the goal of improving not only the efficiency and capability of manufacturing, managing and decision-making but their own economic benefit and competitiveness, many business managers reach the consensus that business process management (BPM) should be regulated, optimized and restructured by enterprise resource informationization (ERI). Surrounded by this atmosphere, Longmay Mining Group launch its march of ERP.Longmay Mining Group has 80 single-unit operating track scales distributed in mines in Jixi, JiXi, HeGang, Shuang Yashan and Qi Taihe to its name. As a result of using different track scales from different weighing apparatus factories and its corresponding cross-scale data-collecting software, it has caused two problems. One is the data format and printed cross-scale vary a lot, the other is that the software functionality is so inadequate that it can only collect its date but fail changing the data with other system. The latter cause a serious problem--- it makes difficult to keep a tight control of weight of car in loading , which leads to overloading ,a serious mishap, a loose control of loading, and sensibility-sparing burden. These trifles can not only cause damage to the enterprise's economic benefits and result in the inaccurate data in the process of transmitting scale data, but also hinder the Railroad Bureau from checking the state of carriages and judging the overload. Therefore, Longmay Mining Group decided to adopt connected railroad track scale project and develop a track scale measurement system ,which can cover integrated measurement needs based on distribution surroundings. By then, it can achieve function of collecting data and governing and managing. What's more , the system will dock the current Dong Tai's sale statement system and TMIS, which means obtaining data and offer a standard TMIS cross-scale data respectively. Based on the Railroad Track Scale Measurement transaction network, this program will focus on designing a system for collecting data in diverse surroundings and providing integrated services.In the system requirements analysis and design phase, The system has designed nearly 80 sets railroad track scale-interconnection network topology, as well as railroad track scale system with third-party clearing system and rail system TMIS docking mode distributed in JiXi, HeGang, Shuang Yashan and Qi Taihe four mines, established the overall business processes after standardizing and optimizing, determined the various functional modules; chosen the C/S software architecture in comparison with B/S mode, adopted structured method and prototype development of the combination of methods to make the general plan, then a prototype method using a specific function modules in the design and implementation , and systems involved in the important business functions carried out a detailed design and implementation.In accordance with the scope of business, the software system is mainly divided into divisions of railroad track scale,service office,railway and measuring room. According to the system function mainly includes system,weighing over,carriage management,metrological management,system maintenance and help. Specific functions include:1,System: include system login,password change,parameter setting and exit system module.2,Weighing over:include the code table and interface parameters downloading, the choice of the pounds member, weighing over planned, weighing over unplanned, local data maintenance, local data query, local data reporting - track scale server, local data reporting - interface server, cross-scale data query, the docking and maintenance of cross-scale data, the maintenance of unplanned cross-scale data. This function is performed by the division to operate the pounds. 3,Carriage Management:include rail query on cross-scale data, start-off management on cross-scale data, railway report on cross-scale data, the query and audit correction on cross-scale data, this part of the function is operated by the mine workers and the Railway Station dispatch operations in accordance with its powers.4,Metrological management:include emergency fill on cross-scale data, the maintenance of local emergency fill data, reporting the emergency data to railroad track scale servers, reporting the emergency data to the interface server, cross-scale data query, the docking of emergency fill cross-scale data and the audit on unplanned cross-scale data .This part of the function is performed by measuring office staff.5,System Maintenance: include system parameter configuration, user management, departure station management, scale management, pound staff management, vehicle model management, coal management, origin management, the match management of the departure station and origin, the match management of the departure station and vehicle species, the relevance management of the Prefix of vehicle number and vehicle Model , log clean, this part of the function is performed by system administrators.This system adopts Delphi7 as the front development tool, Sql Server2000,Access2000 as background of database and ADO,ODAC,CELL and MSComm are applied to development process.Compared with the single way of using one pattern, the approaches of life cycle and prototyping are adopted in the process of analysis and design stage of the system has improved systematic requirements analysis design quality and efficiency; the Third party module ODAC, CELL in the large-scale application of this system greatly improved the efficiency of the system development and interface usability. Instrument communication parameters and the general description of format of the data output, user rights mode also makes the system versatility enhanced. To the coal enterprises using static meter only need to adjust the parameter configuration, the system can be used normally. Therefore, this software can be applied in coal enterprises using a static meterThe system was proved reliable and good effect by the long-time running of coal enterprises such as Longmay Mining Group. It has realized entire process administration of business related to railroad track scale, removed personal error in the process of data transmission and processing,greatly raised the measuring efficiency and made the normalizing and infomationization of measuring work toward a new stage.
