Intelligent lock and use method thereof

A use method of an intelligent lock applied to an intelligent lock comprising a lock body, a main controller, a hand dorsum vein recognition module, a housing, and a lock drive module;

• the main controller being connected to the hand dorsum vein recognition module and the lock drive module;
• the lock drive module being further connected to the lock body;
• wherein the hand dorsum vein recognition module is positioned within the housing and configured to acquire an image of a hand dorsum vein of a target subject at a predetermined angle obliquely downward and recognize the image, so as to obtain target vein feature data;
• wherein the main controller is positioned within the housing and configured to match the target vein feature data with recorded vein feature data to obtain a matching result;
• the matching result comprising a successful match and a failed match;
• wherein the lock drive module is positioned within the housing and configured to drive the lock body to unlock in case of the successful match;
• wherein the housing comprises a first side surface, a second side surface, an elevation-angled interaction surface, and a depression-angled acquisition surface;
• wherein the first side surface, the second side surface and the elevation-angled interaction surface are fixed onto a door;
• wherein the first side surface is opposite to the second side surface, and the first side surface and the second side surface are joined with the elevation-angled interaction surface and the depression-angled acquisition surface;
• wherein the elevation-angled interaction surface is joined with the depression-angled acquisition surface, the first side surface and the second side surface, and an elevation angle of the elevation-angled interaction surface is 130°;
• and
• wherein the depression-angled acquisition surface is joined with the elevation-angled interaction surface, the first side surface and the second side surface, and a depression angle of the depression-angled acquisition surface is 150°;
• the use method comprising:
• placing the hand dorsum naturally in an acquisition space of the intelligent lock;
• acquiring and recognizing, by the hand dorsum vein recognition module, the image of the hand dorsum vein, so as to obtain the target vein feature data;
• matching, by the main controller, the target vein feature data with the recorded vein feature data to obtain the matching result;
• and
• driving, by the lock drive module, the lock body to unlock in case of the successful match.
