The Design And Realization Of Intelligent Broadcast Radio Signal Tester

By analyzing the situations of inspecting and memorizing System for radio coverage effect home and abroad, a system structure for radio coverage effect is put forward here, aimming at the request of the province broadcast monitoring. It is composed of three part: the control center, communicate network and the testing instrument putting in all over the area of the province.The paper accomplished the design of Intelligentized Broadcast Wireless-signal Testing Instrument, aimming the request of testing equipment.With regards to the hardware design, we used radiogram to receive and pretreat with broadcast; we used st2410 to control switchers, which can realize switching channel, and to control the A/D interface to sample and manage the signals; and also to control the display, intermit, note and so on.With regards to the software design, we have realized the A/D, data storage, display and operating of the touched screen and calculate parameter.At the end of the paper, I summarize the matter which must be taken attention to and analyse the errors of the system.
