The invention provides an unmanned vehicle navigation driving method based on a cloud server. A device according to the method comprises three modules, namely the cloud database, an on-vehicle terminal and a ground GPS base station. In the unmanned vehicle, a destination is input through the on-vehicle terminal of the vehicle. Furthermore the destination information, position information and vehicle condition information of the vehicle are transmitted to the cloud database. The cloud database integrates all related information for performing calculation planning, and transmits an optimal driving plan to a vehicle system for execution by a vehicle control system. Furthermore, surrounding environment information is acquired in real time in vehicle driving and is uploaded to the cloud database, thereby realizing real-time synchronous updating of the cloud database and ensuring high reliability and high real-time performance of cloud data. The unmanned vehicle navigation driving method can supply detailed map information for the vehicle on special conditions of rainy or snowy weather, insufficient light at night, covered road surface or covered sign plate, etc.

The invention discloses an alarming device and an alarming method for photovoltaic battery rejected products. The alarming device comprises a photoelectric sensor and an alarming device, wherein the photoelectric sensor is used for detecting whether a battery reaches a disqualified position or not; and the alarming device is connected with the photoelectric sensor and used for issuing an alarm when the photoelectric sensor detects that the battery reaches the disqualified position. When the photoelectric sensor detects the battery reaching the disqualified position, the alarming device issues the alarm, the alarming device is used for monitoring the rejected products in real time, so that the test monitoring personnel can get hold of information at first time when the rejected product appears so as to take relevant measures to reduce the production of mass rejected products or severe quality accident, assistance is provided for the test monitoring personnel, and certain contribution can be made for enhancing the qualification rate of the battery finished products.

The invention discloses a passive determination method for a motion track of an underwater glider platform, and relates to a determination method for a track of the underwater glider platform. Passivetrack calculation of a carrier cannot be carried out at present. The method comprises the following steps of acquiring an average ocean current flow speed and a flow direction of an area where a glider is located according to an entry point location and an exit point location of the glider; computing a vertical movement speed of the glider; acquiring a posture transfer matrix of the glider; acquiring a posture and a posture transfer matrix of the glider at each moment; acquiring an instantaneous speed of the glider at the ith time point under the action of gravity and buoyancy according to the vertical movement speed and the posture transfer matrix of the glider; and acquiring a total speed of the glider according to the ocean current flow speed and the instantaneous speed, integrating the instantaneous speed to obtain three-dimensional coordinate information of the glider at each moment, and combining coordinates at all moments to obtain a glider movement track graph of a complete section. According to the method, the movement track of the glider in one movement profile is obtained, so that passive calculation of the track is realized.
