The invention relates to an all-dimensional environment light collecting device and a fish releasing sign. The all-dimensional environment light collecting device comprises a light collecting ring connected with a light guide branch line, a luminance sensor is arranged on the position of a light outlet of the light guide branch line, and light collected by the light collecting ring can be multiply reflected or totally reflected in the light collecting ring and enter the light guide branch line. The fish releasing sign comprises a cylindrical body which is provided with an installation groove in the circumferential direction, and an all-dimensional environment light collecting device is arranged in the installation groove; the cylindrical body is further provided with a light through hole used for containing the light guide branch line, and the light through hole makes tight contact with the light guide branch line. According to the all-dimensional environment light collecting device and the fish releasing sign, under the circumstance that power consumption and circuit complexity are not increased, luminance in different directions is collected simultaneously.
Description
technical field [0001] The invention relates to the technical field of ambient light brightness collection, in particular to an omnidirectional ambient light collection device and a fish release sign. Background technique [0002] Mark release is an important method to study fish migration rules and living environment. In the early days, fish migration routes were investigated through a large amount of capture location information. With the development of modern electronic technology, archival release signs appeared. The general main structure of the sign is a cylinder, which is equipped with circuit parts and sensors. The sunrise and sunset times are obtained by using the ambient light brightness changes recorded by the brightness sensor, so as to obtain the longitude information; at the same time, the latitude information is obtained by using the daytime length. Get the daily fish activity area, so as to get more complete fish migration information. In this method of ret...
