It’s mainly used to help patients call medical person conveniently, which is the necessary equipment of improving hospital ward nursing level. Calling system needs have the Characteristic of timely, accurate, reliable, simple and feasible. When the calling source has the calling signal, the system has the corresponding sound, indicating light call signal and it can demonstrates the call number. This system mainly consists of AT89S51 single-chip microcomputer as the core design, introduces the implement method of circuit design and software, and gives the system block diagram, hardware circuit and program design, the system uses a high degree of integration of RF transceiver chip franchise for transmission, not only it avoids the traditional wired paging system wiring complexity problems, but also the whole circuit is simple ,stable and performance.
