Problems solved by technology

[0004] However, if it is judged whether there is an interference signal by detecting the number of packet loss per unit time, it usually takes half a minute or more after the interference occurs to take corresponding actions, and the delay is relatively large, resulting in no valid image for a long time. Missed diagnosis

Abstract

The invention discloses an image recorder, an endoscope system and an endoscope system interference signal detection method, the image recorder comprises a receiving antenna, the receiving antenna is connected with a filter, the output end of the filter is connected with the input end of a power detection circuit, and the output end of the power detection circuit is connected with a controller. The endoscope system has the function of monitoring the frequency spectrum in real time, when interference signals exist in the working environment of the endoscope system, a prompt can be given out immediately so as to recover communication as soon as possible, the probability of communication interruption is greatly reduced, and the possibility of misdiagnosis and missed diagnosis is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an image recorder, an endoscope system and a method for detecting interference signals of the endoscope system. Background technique [0002] The existing capsule endoscope systems all include a capsule endoscope and an image recorder. The capsule endoscope shoots images inside the body and sends the images in radio frequency mode. The image recorder receives the images from the capsule endoscope through the antenna. The image is stored, and it also has the function of sending instructions to the capsule endoscope. [0003] Because it is wireless communication and works in a free public frequency band, it is easy to be affected by external interference and affect the communication quality. The same-frequency interference will greatly reduce the signal-to-noise ratio of useful signals, resulting in a large number of bit errors and communication interruption. A communicati...
