R&D Of The Testing System For The Controller Of Broadcast Transmitter

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...
