TOKEN方式在微机能源管理系统中的应用

Application of TOKEN Method in the Microcomputer Energy Management System

TOKEN存取控制方式是一种较新的计算机局部网存取控制技术。本文论述了在微机能源管理系统中应用该方式的合理性和可行性。并分析了微机能源管理系统作为一种特殊的计算机局部网的特点,提出在选择存取控制方式时应强调二个方面:一是提高吞吐量以确保数据的实时性,二是要结合整个系统的有效工作来考虑网络的有效性问题。同时对常用的局部网存取控制方式进行了对比,提出了采用TOKEN方式较为合理的观点。最后,给出了一个采用TOKEN方式的微机能源管理系统的实例。

TOKEN access control method is a kind of new access control technique in local networks. In this paper, such questions as possibility of and reasonableness for the application of TOKEN method in microcomputer energy management system (MEMS) are discussed. Here, features about MEMS, considered to be a special local computer networks, have been analysed. In chooosing access control method, emphasis should be placed on two aspects: one is improvement of throughput in order to assure data real-time; the other is that efficiency of networks should be taken into account on the basis of effective working of the entire system. From this point of view, some common access control methods have been contrasted and a more reasonable point-TOKeN method is proposed. Finally, give an example of MEMS in TOKEN method.
