The Design Of Intelligent Instrument Monitoring Platform Based On Wireless Network

With the development of scientific and technological progress, the modernization of the symmetrical heavy technology has put forward higher requirements. At present, the electronic weighing technology has been widely used in business and industry, the relationship between the technology and all walks of life are increasingly inseparable. At present the majority of our plant weighing measurement using artificial way to operate, application of the existing wireless network, very little by macroscopic decision will result in some error and error, and weighing data collection, access, and analysis is relatively complex, resulting in a waste of human resources, which affects the production efficiency.Aiming at the above problems, the design of intelligent weighing instrument monitoring system based on wireless network. This design mainly by the measurement end weighing apparatus, the AP server, Android client monitoring system several parts composition. Weighing apparatus of measuring end after the weighing sensor weighing data after amplification, filter circuit, A / D conversion circuit after transfer to the microcontroller, to achieve the accurate measurement of the pressure. Monitoring system using Android client as the system monitoring terminal. The AP server as a Wi Fi access point, allowing Android handheld devices and the measuring end weighing constitute a system network via Wi Fi access within the working area of all scales are monitored. And the AP server has the function of data processing and storage, data transmission and so on. In the software system structure, through the comparison of the two modes of B/S mode and C/S mode, the system scheme based on C/S mode is selected, and the overall scheme design is carried out. Analysis of Android system Wi-Fi communication mechanism and the realization of the SQLite Android database, and with the function of the interface diagram analysis of the entire monitoring systemfunction realization of the specific process.Based on wireless network intelligent weighing apparatus monitoring system to realize the Android phone on measuring weighing system of remote visual monitoring and receive real-time display sensor data, and can be check weighing apparatus, call history data, of the scales were switch control function,realizes the real-time monitoring on the measurement end, into the integrated remote monitoring equipment, capable of data analysis, remote diagnosis, remote control and other functions. The design scheme can also provide reference for the related research field, which has certain practical significance and application prospects.
