【摘要】：伴随着工业的高速发展,生产规模的不断扩大,大型流水生产线已成为主流的生产模式。随着生产效率的提升,企业对产品质量日趋关注,检重秤被越来越多的产品制造商所采用。目前国内企业对检重行业也愈加关注,但其研发的产品检重精度和检重速度并不是太高,而且需要占用人力对设备的运行状态进行监测,造成大量的人力资源浪费,增加了生产成本。针对现在国内检重行业存在的问题,设计研发一款基于无线通信技术的检重秤及监测系统。该系统集检重测量与监测于一体,检重装置主要利用称重传感器将待检物体的重量信息转换为电信号,通过A/D转换模块对信号进行放大并转换为数字信号传递至微处理器。为了提高检重的精度,微处理器采用卡尔曼滤波算法和最小二乘支持向量机实现对干扰的滤除和检重终值的预测。为了实现对检重装置相关运行参数的检测,系统采用Wi-Fi无线通信模块实现检重装置的网络连接,同时设计一款以Android智能手机为载体的移动监测应用。通过组建以AP为基础核心的覆盖工厂的无线局域网络,实现检重装置与移动监测端之间的数据传输。移动监测端需要对检重装置的检重数据、运行状态及相关参数等信息进行监测,这就需要在二者之间进行大量的数据传输。为了充分发挥系统的性能,提高系统的处理能力,设计选用C/S体系结构作为监测系统的软件系统体系结构模式。基于无线通信技术的检重秤及监测系统实现了对物件重量的精准测量和对检重装置运行信息的监测。与以往的设备相对比,它提高了检重的精度和检重速度。同时通过移动监测端实现对检重装置的远程监测,减少了人力资源的投入,降低生产成本,实现了工业生产过程的智能化管理。
[Abstract]:With the rapid development of industry and the expansion of production scale, large production line has become the mainstream production mode. With the improvement of production efficiency, enterprises pay more and more attention to product quality. At present, domestic enterprises are paying more and more attention to the heavy inspection industry, but the precision and speed of the products developed by them are not too high, and they need to use manpower to monitor the running state of the equipment, resulting in a large amount of human resources waste. Increased production costs. Aiming at the problems existing in domestic weighing industry, this paper designs and develops a scale and monitoring system based on wireless communication technology. In this system, the weight information of the object to be detected is converted into electrical signal by using the weighing sensor, and the signal is amplified and converted to digital signal through the Ar / D conversion module. In order to improve the accuracy of detection, the Kalman filter algorithm and least square support vector machine are used to filter the interference and predict the final value. In order to detect the operation parameters of the weighing device, the Wi-Fi wireless communication module is used to realize the network connection of the device, and a mobile monitoring application based on Android smart phone is designed. A wireless local area network based on AP is set up to realize the data transmission between the weight-checking device and the mobile monitoring terminal. The mobile monitoring terminal needs to monitor the information of the weighing data, the running state and the related parameters of the device, which requires a large amount of data transmission between the two. In order to give full play to the performance of the system and improve the processing ability of the system, the C / S architecture is selected as the software system architecture model of the monitoring system. Based on the wireless communication technology, the weigher and its monitoring system can accurately measure the weight of the object and monitor the operation information of the device. Compared with the previous equipment, it improves the accuracy and speed of weight check. At the same time, the remote monitoring of the weight check device is realized through the mobile monitoring terminal, which reduces the input of human resources, reduces the production cost, and realizes the intelligent management of the industrial production process.
