Abstract:With the development of science and technology, the wireless application technology has penetrated into every field of life, wireless transmission technology is also more and more mature. This design is the wireless transmission technology is applied to clinical research subject, the realization based on single chip microcomputer wireless transmission module wireless multi-channel sickbed call system.

　　　This paper STC89C52 as control core, through the wireless transmitting module launch transmission signal, wireless receiving module receiving signals, the STC89C52 treatment shows that the output, so as to realize the patient and medical wireless distance communication. The sickbed call system can realize 100 m distance launch receiving, also can around obstructions transmission, its stable performance, take up the space is little, use little material, transmission speed and distance, and can satisfy the requirements of clinical application
