Embodiment Construction

[0022] A method for controlling a receiving antenna of a capsule endoscope, the steps of which are:

[0023] 1) According to the database information, initialize the positions of antennas T1 and T2;

[0024] 2), Two antennas, one is controlled by the controller to receive data, and the other is mobile;

[0025] 3) The controller drives the mobile antenna to move the position, and finds a stronger signal position than the antenna receiving data at this time:

[0026] The specific steps of the first movement: establish the XY axis coordinate system corresponding to the rotation axis in the plane, and control the rotation of the corresponding rotation axis to control the antenna to move in the XY plane. First, move to one direction of the X axis to determine whether the signal strength is greater than If it is greater than the initial position, it will continue to move in this direction, and if it is less than, it will return to the position with the strongest strength. The move...

Abstract

The invention provides a receiving antenna control device and control method of a capsule endoscope. The method comprises the steps of: 1, initializing positions of antennas T1 and T2; 2, controlling the two paths of antennas through a controller, wherein one path is controlled to receive data, and the other path is controlled to move and find a position higher in signal strength; 3, switching receiving, and moving the antennas; and 4, recording data, and carrying out prior position adjustment for the next time of working. By adopting the above method, a self-updating learning algorithm is used to control the movement of the antennas, and the antennas can rapidly track the position of a capsule, the optimal signal receiving strength is maintained, and the capsule data can be stably received without lose.

Description

technical field [0001] The invention relates to a receiving antenna control device and a control method of a capsule endoscope, belonging to the technical field of capsule endoscope application. Background technique [0002] The receiving antenna device of the capsule endoscope generally uses multiple antennas to receive the wireless data transmitted by the capsule endoscope. Because the wireless signal has a large attenuation in the human body, and the attenuation will increase rapidly as the distance between the capsule and the receiving antenna increases. In the current existing technology, in order to reduce data loss, it is necessary to arrange multiple receiving antennas on the human body, generally greater than or equal to 8. These antennas are constantly switched to find the antenna with the highest receiving level for data reception. However, the position of the antenna on the human body is generally placed in a fixed position based on experience, and because of d...
