Design And Application Of Weighing Management System For Industrial Platform Scales

Weighing is widely used in industrial production. Manual management is used in traditional weighing mode s of weighing, so all kinds of disadvantages exist in this mode.For example, the manual record is not accurate and efficient, otherwise it is difficult to query the historical data. In order to solve above problems, an industrial weighing management system is designed in this paper. It is composed of a Host computer, IND231 weighing instruments, industrial monitoring cameras and a video acquisition card. Host computer can not only read real-time and accurate data from IND231 weighing instruments through serial communication, but also capture and store the video information of the production workshop. The storing of data is automatic, the records of data are traceable, and the industrial operation is visualization by the application of industrial weighing management system, so it would to be with a wide application prospects.The main work of this topic is as follows.Firstly, the principle of the industrial weighing management system is introduced,and the hardware design is completed. The standard configuration of the industrial weighing management is composed by two components: the data transmission, storage and query part made up of one Host computer and four IND231 weighing instruments;the video capture, record part made up of four industrial monitoring cameras, and a video acquisition card. The industrial weighing management system is designed according to the request of storing and querying of weighing data, recording and monitoring of video information. Then the hardware equipment is selected.Secondly, the software of the industrial weighing management system is designed.The communication program between Host computer and IND231 weighing instrument is written by the language of VB, so the weighing data can be uploaded. The user login, data storage, real-time display, historical query function module are programmed in VB.Thirdly, the industrial weighing management system has been applied to the workshop of Kehai Biological Limited Liability Company in Qingdao. This system is made up of one Host computer and two IND231 weighing instruments according to the actual needs. After it is debugged, it runs stable and reliable. The shortcomings existed in the manual record were overcome.Practical application indicates, using the industrial weighing management system,the weighing process is supervised effectively, and the whole production process of the firm can be traced, so production management level of weighing is improved obviously.
