【摘要】：为了适应企业的发展，企业的信息化系统也不断发展完善。这种完善的过程是，提出问题解决问题的过程。本文讨论了我公司在部分外库使用的汽车衡电子秤系统，经过对秤单出错情况分析，发现很多错误是由于人为因素导致的，因此提出对汽车衡电子秤系统进行改造。该系统需要完善的地方有：称重系统能完成单点称重任务，但不具备联网称重功能，缺乏灵活性；称重系统与视频监控系统不能协同工作，秤单信息没有对应的车辆过秤图片；称重系统没有记录日志信息，不便于分析问题；称重系统依靠人工判断车辆是否停稳等。本文的研究课题是在原有汽车衡电子秤系统的基础上，根据使用过程中发现的问题，对汽车衡电子秤系统软件进行改造升级，使其具备以下新功能：可以进行联网称重；在保存秤单信息的同时，保存对应车辆过秤时的图片；记录下的称重日志信息包括，修改和删除秤单信息的记录、重复打印秤单的记录，这样便于发生问题时进行分析；称重系统自动对上秤车辆判稳等。在软件改造过程中，绘制了用例图、数据流图、数据库整体架构。软件测试方面，在编程的不同阶段应用白盒测试、黑盒测试、Alpha测试、Beta测试对软件进行测试，以保证软件的质量。经过1年多的时间，完成了本文研究课题的内容，改造后的系统现已投入使用，各个改造升级后的功能正常，，系统运行稳定。相关部门在2013年底，对秤单出错率进行了统计分析，在过秤总量与2012年相近的情况下，秤单年出错率由0.3％降低到0.1％。说明通过使用改造后的称重系统降低了秤单的出错率。
[Abstract]:In order to adapt to the development of enterprises, the enterprise information system is also constantly developing and improving. This perfect process is the process of putting forward a problem to solve a problem. This paper discusses the electronic scale system of automobile scale used in part of the external storehouse of our company. By analyzing the error of the scale sheet, it is found that many mistakes are caused by human factors. Therefore, the modification of the electronic scale system of automobile scale is put forward. The system needs to be perfected as follows: the weighing system can complete the single point weighing task, but it does not have the network weighing function, lacks the flexibility, the weighing system and the video surveillance system cannot work together, the weighing information does not have the corresponding vehicle weighing picture; The weighing system does not record the log information, so it is not convenient to analyze the problem, and the weighing system depends on manual to judge whether the vehicle stops or not. On the basis of the original electronic scale system of automobile scale, according to the problems found in the process of using, the software of electronic scale system of automobile scale is reformed and upgraded, which has the following new functions: it can be weighed through network; At the same time, the information of the weighing list is saved, and the pictures of the vehicle when passing the scale are saved; the information of the weighing log recorded includes modifying and deleting the record of the information of the scale, printing the record of the scale repeatedly, so as to facilitate the analysis when the problems occur. The weighing system automatically adjusts the vehicles on the scale and so on. In the process of software transformation, the use case diagram, data flow diagram and the whole structure of database are drawn. In the aspect of software testing, white box test is used in different stages of programming, and black box test Alpha test beta test is used to test the software to ensure the quality of the software. After more than one year, the contents of this thesis have been completed. The reformed system has now been put into use, the function of each revamped and upgraded system is normal, and the system is running stably. At the end of 2013, the error rate of weighing list was statistically analyzed. When the total amount of weighing was close to that of 2012, the annual error rate of weighing was reduced from 0.3% to 0.1%. It is shown that the error rate of the weigher can be reduced by using the modified weighing system.
