Abstract: The present application discloses a micro electrostatic purification device for resisting high humidity, including an ionization module, a micro electrostatic filter and a power supply module, the two ends of the insulating dielectric material in the cartridge carbon electrode length direction are installed inward respectively into the first electrode strip and the second electrode strip, and finally closed with a sealant, and the connection of the individual wire is sealed by filling sealant, to achieve the complete closure of the cartridge. The connection between the power module and the electrode strip, and the connection between the electrode contact piece and the external power supply are all completely sealed through the setting of the structure. And a current limitation protection circuit is provided to monitor the working current in real time and carry out current limitation protection when the instantaneous change of the working current exceeds the threshold.

Abstract: A robot with the perception capability of livestock and poultry information and a mapping approach based on autonomous navigation are disclosed. The robot includes a four-wheeled vehicle (3), an autonomous navigation system, a motion module and an information acquisition module. The autonomous navigation system includes a LiDAR (10), a RGB-D camera (9), an inertial measurement unit (5), an odometer and a main control module (12). The information acquisition module includes two thermal imagers (6), an environmental detection sensor module (8) and a wireless transmission module (11). The robot is controlled in indoor working environment, and simultaneously information about surrounding environment during movement is obtained with the autonomous navigation system; positioning locations are obtained through data processing and a global map is constructed, which can improve positioning accuracy, reduce dependence on breeders, realize automatic environment detection.
