中央空调远程控制及计费系统的研制

Development of remote control and billing system for central air-conditioning

针对中央空调体系庞大,难以进行远程控制,分摊计费等问题,基于嵌入式平台,使用B/S架构,设计并实现了具备分摊计费功能的中央空调控制管理系统。从硬件的接口设计,软件的通信流程剖析,到计费算法的改良等方向详细地阐述了该系统的设计思想。该系统使用B/S架构,在满足跨平台设备使用的同时降低了部署复杂度;搭配FPGA,在保证通信速率的同时,将可接入设备拓展到4 096台;采用SQLite数据库配合改良后的计费算法,完成分摊计费存储显示等功能。实际运行表明,该系统远程控制功能高效稳定,分摊计费功能合理精准,很好地解决了当前中央空调管理系统所面临的问题。

In view of the huge central air-conditioning system, it is difficult to carry out remote control, sharing billing and other issues, this article is based on the embedded platform, using B/S architecture, design and implement a central air-conditioning control management system with sharing billing function. From the hardware interface design, software communication process analysis, to the improvement of the charging algorithm, the design idea of the system is elaborated. The system uses the B/S architecture, which reduces the complexity of deployment while satisfying the use of cross-platform equipment. With FPGA, while ensuring the communication rate, expand the accessible devices to 4 096 units. Use SQLite database and improved charging algorithm to complete functions such as apportioned charging storage display. The actual operation shows that the remote control function of the system is efficient and stable, and the apportionment billing function is reasonable and accurate, which solves the problems faced by the current central air-conditioning management system.
