摘要
饲料配方软件为合理利用饲料资源、降低饲粮成本发挥了巨大作用。在掌上电脑上设计和开发了通用型饲料配方系统,系统包含配方计算、配方浏览、数据管理、系统维护和系统升级等主要功能模块。开发了嵌入式数据库访问中间件,提高了掌上电脑上数据操作的效率和系统的稳定性;采用两阶段法和直接计算逆矩阵的方式对配方求解的单纯形算法进行了优化,根据参算原料种类的数量,实际计算一次配方时间约为2～4s;实现了基于存储卡和网络的两种升级方式,保证了系统原料和饲养标准数据的时效性。在北京市4个郊区县31个养殖场户进行了应用,结果表明,系统稳定实用、操作简易,容易被中小养殖户接受,具有较大的推广价值。
The applications of feed-formula systems play a great role in reducing the feed cost and increasing the utilization efficiency of raw materials. The development of general feed-formula system based on Pocket Personal Computer （PC） was described in this article. Main function modules include formula calculation, formula review, data management, system maintenance and system updating. The efficiency of data operation and system stability were improved by using the developed middlewares for embedded database. The formula generation algorithm was optimized using two-step algorithm and direct inverse matrix computation. According to the number of the kinds of target materials, the actual computation time was 2-4 seconds. The time-effectiveness of data was guaranteed through the system updating methods based on memory card and network. Through the applications of this system in 31 feed farms of 4 counties in Beijing, it indicated that the Pocket PC based feed-formula system had those advantages： stable and practical, easy to use, easy to be accepted by middle and small feeding farmers. It has wide application prospect and popularization value.
