The invention provides a method, a device and a terminal for parking an unmanned vehicle. The method comprises the following steps: acquiring fault information of the unmanned vehicle; judging whetherthe unmanned vehicle is controlled to park or not according to fault information, and if so, acquiring environmental information around the unmanned vehicle; generating a parking strategy according to the environmental information around the unmanned vehicle and the fault information; controlling the unmanned vehicle to park in a destination region according to the parking strategy. The method, the device and the terminal provided by the invention ensure parking safety in complex environment, improve safety of passengers, and also ensure smooth flow of traffic.

The invention provides a multi-point networking communication system comprising an intelligent control host and an equipment node network. The intelligent control host and the equipment node network form a star network. Point-to-point communication is performed between the intelligent control host and the equipment node network through control instructions. The equipment node network includes countless equipment nodes. A wireless transmit-receive module is embedded in each equipment node to act as the wireless communication hardware basis. The intelligent control host comprises a host node, a core processor and an RF module. The host node is used for processing the serial port instructions of the core processor. When the host requires to communicate with the equipment, the core processor transmits the instructions to the RF module through serial ports, then the RF module wirelessly forwards the instructions to the equipment nodes, and the equipment receives information and then performs processing and feedback according to the respective attribute state. Each equipment node and the host node have a unique equipment address ID, wherein the equipment address ID uses the internal ID of the chip so as to guarantee the uniqueness.

The invention relates to a mechanically controlled underwater dual-channel connecting and locking device. A pipeline body of the mechanically controlled underwater dual-channel connecting and locking device is mainly composed of an upper body, a lower body and a locking device, wherein the upper body and the lower body are respectively provided with two channels in a penetrating mode; two adjacent connection channels are formed inside the pipeline body after the upper body and the lower body are connected; the connection faces of the upper body and the lower body are provided with two paths of connection seals; the two first connection seals are formed at the position where the first connection channel and the second connection channel are connected; one second connection seal is formed on the periphery of the two first connection seals; one seal testing channel is arranged on the upper body; one end of the seal testing channel is open, is arranged on the face where the upper body and the lower body are connected and is located between the first path of connection seals and the second path of connection seal; the locking device is arranged outside the pipeline body and fixedly connects the upper body with the lower body. According to the mechanically controlled underwater dual-channel connecting and locking device, much occupied space is saved due to connected pipelines, the effective sealing performance is ensured, operation time for connecting the pipelines by an underwater ROV is shortened, and expenses and cost are lowered.

The embodiments of this specification provide a model-based forecasting method and device. One method is executed on the data demand side, and the data demand side includes a pre-trained calculation model. The method includes: through at least One parameter is encrypted to generate an encrypted model; the encrypted model is provided to a data provider, wherein the data provider stores first data; A calculation request of the model; receiving a calculation result corresponding to the calculation request from the data provider; and obtaining a plaintext prediction result of the calculation model based on the calculation result.

The present invention provides a heterogeneous data service providing method, device, equipment and medium. The method includes firstly performing general service configuration according to the data source; after the general service configuration is completed, the corresponding data service is automatically generated immediately; when the data source is a database , the general service configuration includes: fill in the service number, select the service type, configure the transfer parameters, select the data source, and fill in the configuration information. It can be realized only by reconfiguration, forming a mechanism for dynamic changes to take effect in real time, and also provides strong support for rapid response to service changes.
