Infrared radio communication system applied to medical equipment

Abstract

The invention discloses an infrared radio communication system applied to medical equipment, comprising an infrared emitting device and an infrared receiving device. The infrared radio communication system is characterized in that the infrared emitting device respectively loads analogue signals and digital signals on high-frequency signals with different frequencies by FM (Frequency Modulation) and then carries out infrared light emission, and the infrared receiving device converts the infrared light signals into electric signals to amplify and then respectively demodulates the analogue signals and the digital signals. The invention does not influence the use of machines in other rooms when a machine is used in one room by adopting the infrared communication; the reliability of the communication is greatly improved by using the FM technology; the analogue signals with extremely large data quantity can be transmitted in high fidelity even under lower carrier wave by using two communication ways of the analogue signals and the digital signals, the digital signals can be transmitted, and the operation can be controlled by transmitted command; and the mutual influence of analogue and digital communication can be avoided by using analogue signal and digital signal time-sharing emission technology.

Description

technical field [0001] The invention relates to the field of wireless communication of medical instruments, in particular to the field of using an infrared wireless communication device for communication when an analog signal and a digital signal need to be transmitted simultaneously. Background technique [0002] At present, most medical devices on the market use infrared communication for the transmission and reception of analog signals. For example, fetal heartbeat Doppler only transmits fetal heart sounds. It cannot perform digital communication, so it cannot use the probe to control the host. Thereby greatly restricting the freedom of doctor's operation, has certain limitation. Contents of the invention [0003] In order to solve the above problems, the present invention provides a communication device for the integration of analog and digital communication in medical equipment, which has high reliability, simple circuit and low cost, and can meet the requirements of ...
