Signal compensation circuit of medical remote monitoring system

Abstract

The invention discloses a signal compensation circuit of a medical remote monitoring system. The signal compensation circuit comprises an anti-interference circuit, a compensating circuit and a differential output circuit, wherein the anti-interference circuit receives signals in a signal transmission channel of the medical remote monitoring system, removes interference signals through filtering by a composite circuit consisting of a diode D4, a triode Q1, a voltage stabilizing tube Z1 and a thyristor VTL1, and finally processes and outputs single-frequency stable signals by a frequency-selecting filter circuit consisting of a resistor R5, a resistor R6, a capacitor C7, inductors L2 and L3 and a capacitor C8, and the signals then enter the differential output circuit and are output; the compensating circuit is used for providing stable power supply for the anti-interference circuit, compensating nonlinearity of interference suppressing signals of the anti-interference circuit and providing compensating signals for the output signals of the differential output circuit, so that amount of attenuation in the signal transmission process is further compensated, the signals in the signaltransmission channel of the medical remote monitoring system are effectively stabilized, and the phenomenon of signal attenuation is eliminated with the compensation method.

Description

technical field [0001] The invention relates to the technical field of medical remote monitoring, in particular to a signal compensation circuit of a medical remote monitoring system. Background technique [0002] With the development of science and technology, the level of modern medicine has also entered a new field. The introduction of large-scale medical equipment has made modern medicine enter a new stage. Advanced medical equipment is an important symbol of a hospital's modernization level, and it is also the basic condition for the continuous improvement of medical technology. The complexity of the remote monitoring system for large-scale medical equipment determines that it is impossible for humans to monitor in real time. This will not only waste a lot of human resources, but also make it difficult to give early warning. The remote monitoring solution can easily cluster distributed medical equipment management, early warning, etc. [0003] The current medical remo...
