摘要：
针对目前空调外机安规测试人工操作模式效率低、测试不稳定、测试数据不能保存、难以满足智能制造的需求等问题,调查了现有空调外机生产线体结构、安规测试工艺及测试流程,研究了空调外机安规测试,设计了安规测试电路.以ATmega128和ATmega16为核心控制器件,分别设计了主站和从站,并构建了主从式模块化测控网络硬件系统;开发了基于RS-485的主从网络通信协议,主站控制安规测试仪器进行测试和采集数据,测试数据经无线传输系统输入企业生产管理平台.上述模块构成了自动安规测量及控制网络系统,并具备抗干扰能力.自动安规测控网络能够嵌入到空调外机现有生产线体,适用于不同空调机型的安规测试.生产实践运行表明,自动安规测控网络设计符合空调外机安规测试生产和工艺要求,为样机的设计应用及其他电气产品的安规检测自动化研究奠定了基础.%Aiming at the shortcomings of manual operation mode of safety tests for air conditioning external machines,e.g.,low efficiency,unstable test,the test data cannot be stored,the demands for "intelligent manufacturing" are difficult to be satisfied,etc.,the existing structure of production line and safety test process of the air conditioning external machines are investigated.The safety test of the air conditioning external machine is researched,and the test circuit is designed.The hardware system of the embedded modular test and control network is designed,including the master station with the ATmega128 as the core and the slaver station with the ATmega16 as the core;the RS-485 based master-slave communication protocol is developed,the master station controls the test and collects the data,and the test data are input to production platform of enterprise via wireless transmission system.The modules above construct the automatic safety test and control network system,and the anti-interference design is conducted.The automatic safety test and control network can be embedded into existing production line of the external machines.It is suitable for the safety test of different types of air conditioners.The practical production shows that the design conforms the productive and technological process requirements,and lays the foundation for the research and application of prototype design and other electrical products.
