Problems solved by technology
[0004] The impedance matching is maintained by a fixed matcher between the antenna and the signal processor. The fixed matcher can match the antenna in free air. However, since the antenna is a vulnerable device, once the antenna is worn on the human body, it will be affected by the human body. Afterwards, the standing wave will change, so that the matching between the antenna and the fixed matcher will no longer follow the fixed parameters in free air, and impedance mismatch will occur, resulting in serious energy reflection, resulting in reduced transmission efficiency, signal distortion, and system power consumption. rise and other consequences
[0005] Therefore, how to avoid the impedance mismatch of the antenna of the image recorder is a technical problem that those skilled in the art need to solve at present

The invention discloses a matching-adjustable image recorder, which comprises an antenna and a signal processor as well as a standing-wave detector which is connected to the antenna and is used for detecting standing-wave change, a controller which is connected to the standing-wave detector and is used for computing matching parameters in accordance with the standing-wave change, and an adjustablematcher which is connected to the controller, the antenna and the signal processor and is used for dynamically keeping impedance matching between the antenna and the signal processor in accordance with the matching parameters. According to the matching-adjustable image recorder provided by the invention, the impedance matching between the antenna and the processor can be dynamically kept by the adjustable matcher in accordance with the matching parameters in a process of conducting signal transmission, so that radio frequency signals, which are received by the antenna, are transmitted to thesignal processor, and the radio frequency signals are processed via the signal processor and are reduced into image data; therefore, a circumstance of impedance mismatch between the antenna and the signal processor is avoided. The invention also provides a matching-adjustable image transmission method and a capsule-type endoscope system; and the beneficial effects can be achieved.
Description
Technical field [0001] This application relates to the field of medical equipment and communication technology, and in particular to an image recorder with adjustable matching, an image transmission method, and a capsule endoscope system. Background technique [0002] The full name of the capsule endoscope is the "smart capsule digestive tract endoscope system", also known as the "medical wireless endoscope". The principle is that the subject can take a smart capsule with a built-in camera and signal transmission device orally to make it move in the digestive tract and take images with the help of digestive tract peristalsis. The doctor uses an external image recorder and image workstation to understand the subject’s entire digestive tract Circumstance to make a diagnosis of his condition. [0003] At present, the capsule endoscope on the market collects image data in the human digestive tract and transmits it to the image recorder through wireless communication. The antenna of th...
