摘要： 提出了一种基于特殊网络安全机制的空调测试系统，在测试微机与办公微机之间制定通信协议，利用办公微机作为数据传送的中继站，将测试微机和查询网络有效隔离。系统既实现了测试数据的远程查询，又保护了测试系统免于病毒的侵袭以及其它干扰。

Abstract: This paper presents a testing system of air-condition based on a special network security strategy. A communication protocol is made between the testing machine and the office machine. The office machine acts as the relay station for data transfer and isolates the testing machine from the query network efficiently. The system can not only implement the remote query for testing data, but also protect the testing system from infecting viruses and other interferences
