【摘要】 近年来,随着科学技术的迅速进步,自动化的发展进入了一个新的时期。广播发射机实现自动化与智能化是当今世界的发展趋势和技术要求。在这种情况下,广播发射机微控制器应运而生。广播发射机微控制器作为广播发射机的重要组成部分,其能否正常运行关系到广播发射机能否正常工作。为了方便快捷的检测发射机微控制器是否出现故障,研制开发一套微控制器测试平台显得很有意义。本文研究的内容主要包括以下几个方面:(1)从分析测试平台的意义及功能要求着手,确定了测试平台应该具备的检测控制器软硬件故障的功能。具体功能包括测试广播发射机控制器的开关机流程;能输入和输出模拟量、开关量以此来检测发射机控制器数据采集是否正确;检测控制器对发射机出现故障后采取的保护措施的正确性。(2)进行系统的总体框架设计,结合该测试平台的实际情况,采用了上位机/下位机模型。下位机负责将来自广播发射机控制器的控制命令传给上位机,并且执行上位机所发出的指令。上位机负责人机交互、整个测试过程的处理等工作。(3)从硬件方面和软件方面对测试平台进行了阐述。硬件方面详细介绍了电路原理设计,电路元器件的选用等。在对微处理器进行选择后,根据发射机控制器的输入输出通道的特点,确定了测试平台的输入输出通道以及人机接口;软件方面则根据系统所要完成的功能并结合硬件电路,将其划分为三大部分,即上位机程序、下位机程序以及上下位机的通信程序,并分别对三部分程序的具体功能进行了详细的阐述。(4)介绍了测试平台更多还原

【Abstract】 Recently, along with the rapidly development of the science and technology, a new era in the domestic automatization field comes. The intelligentized and automation of radio transmitter is an inevitable trend. The controller of the broadcast transmitter controller emerges under the circumstances, as an important component part, its working status directly affects the whole transmitter’s working status. In order to test the controller’s eligibility, a special testing platform is proposed in this paper.The testing platform for controller of transmitter is indicated according to the following terms: firstly, the discussion of the function the flat should have. It includes the test of simulating transmitter’s on-off; supplies various analog-in, digital-in data to controller and receiving the digital-out data from controller, also making corresponding responses to simulate transmitter; and testing controller’s reaction when the testing flat simulates transmitter’s malfunction; Secondly, the holistic frame is introduced: considering the actual instance, a host/guest model is adopted, the receiver transmit the common from the controller to host, and execute the instruction send by host, the host takes charge the man-machine conversation and sending user’s instruction. Thirdly, expatiates the testing platform aiming at hardware and software: introduces the circuit design in detail, parts’selection. After confirming the type of CMOS chip, base on the characteristics of controller’s input and output channels, the更多还原
