太阳能中央热水工程通讯网络的几个关键问题

Several Key Problems of the Solar Energy Central Hot Water Engineering Communication Network

针对太阳能中央热水工程中通讯网络对维护和管理难度小、工程成本低和高可靠性的要求,结合无线数传技术和嵌入式Internet技术,采用无线通信与以太网相结合的方式设计通讯网络.在软件系统中建立多任务消息机制,引入限时服务策略对任务的运行时间进行约束,提高了软件的可靠性.相关技术已成功应用于景德镇规划局的多个可再生能源示范项目中.

In view of the requirements of few difficult maintenance arid management, low engi- neering cost and high reliability of the solar energy central hot water engineering communication network, in this paper, combined with the wireless data transmission technology and embedded Internet technology, the communication network is designed by using of the wireless communi- cation and internet. In the software system, the multitasking message mechanism is estab- lished, and the limited time service strategy is introduced to constrain the running time of the task, and the reliability of the software is improved. Related technology has been successfully applied to the multiple renewable energy demonstration projects under the administration of the Jingdezhen planning bureau.
