【摘要】：随着消费电子和无线市场的巨大需求,中国在设计、制造和测试复杂半导体方面的技术已经取得了明显的进步,而自动化测试技术的出现为复杂设备系统的测试诊断开辟了一个新途径,因此在未来IC测试中将扮演重要角色。测试产业一个明显的反应就是确保测试平台的可扩展和灵活性。作为医药卫生体制改革的一部分,医疗器械电子产品地不断普及促进了电子测试技术在医疗设备中的广泛应用。本文通过对一款提醒病人按时服药的电子产品的分析,构建了以单片机为核心,并配以一定功能的外围电路,完成测试该产品是否合格的自动化测试系统。整个系统的实现是基于Microchip的PIC系列器件PIC16F877A芯片进行的。在单片机的最小系统的基础上对系统的配置电路、驱动电路、电流测量电路、显示控制电路和报警提示电路进行规划设计,并给出了各个模块的电路原理图,再通过软件设计将所采集到的数据采用串口通信传送给PC机,同时结合上位机应用平台直观地显示出测试产品的各个测量参数,用以判断每个待测产品是否合格。本系统是以实际工程中智能测试架的制作为背景而设计的,涉及到智能测试诊断技术及测试诊断信息的表达等关键技术,顺应了自动化测试系统在电子行业中低成本、高效率的需求,具有一定的实际意义。
[Abstract]:With the huge demand in the consumer electronics and wireless markets, China has made remarkable progress in designing, manufacturing and testing complex semiconductors. The emergence of automated testing technology opens up a new way for the testing and diagnosis of complex equipment systems. So it will play an important role in IC testing in the future. One obvious response from the test industry is to ensure the scalability and flexibility of the test platform as part of the reform of the medical and health system. The popularity of electronic products of medical devices has promoted the wide application of electronic testing technology in medical equipment. Through the analysis of an electronic product that reminds patients to take medicine on time, a single chip microcomputer is constructed as the core. And with a certain function of peripheral circuits to complete the test of whether the product is qualified automated test system. The realization of the whole system is based on the PIC16F877A chip of PIC series device of Microchip. On the basis of the minimum system of single chip microcomputer, the configuration circuit, driving circuit, current measuring circuit of the system, The display control circuit and alarm prompt circuit are designed, and the circuit schematic diagram of each module is given. The data collected is transmitted to PC by serial communication through software design. At the same time, the measuring parameters of the test product are displayed intuitively with the application platform of the upper computer, which is used to judge whether each product to be tested is qualified or not. The system is designed on the background of the manufacture of intelligent test stand in practical engineering. It involves the key technologies such as intelligent test diagnosis technology and the expression of test diagnosis information, and conforms to the low cost of automatic test system in electronic industry. The demand of high efficiency has certain practical significance.
