| Abstract: | With the development of information technique, it is urgent to provide the capability of digital communication for the short-wave radios which are generally used for audio communication in remote country. For this reason, a novel interface circuit is designed in order to meet the requirement of field operation in oilfields. The wireless transmission of digital signal is realized by using single-chip AT89C2051 as a kernel of hardware. The hardware circuit and programming flow chart are presented. The design of short-wave data transmission interface circuit makes full use of the current short-wave radios and meets the continuously increasing demand of the data transmission in oilfields. |
