A method for real-time assessment of natural disaster losses based on social media data, specifically comprising the following steps: step 1, using natural disasters as keywords to obtain social media text data; step 2, extracting text data, and processing the data to complete the text Word segmentation and emotional calibration of data; step 3, establish natural disaster-related thesaurus and anti-thesaurus; step 4, clean text data based on natural disaster-related thesaurus and anti-thesaurus thesaurus and social media data geographic information; step 5. Set the analysis period, obtain the historical disaster data of natural disasters in the analysis period, establish a multiple linear regression model, and perform iterative calculations until the significance level of the model coefficient is less than the set threshold.

The invention provides a knowledge graph Chinese question answer retrieval method based on a dynamic programming algorithm. The method aims at modeling the original question answering process comprising three substeps into the same process in a unified mode, the entity recognition process and the question answer retrieval process are modeled with a same model by integrating thoughts of a state machine in form language, the entity recognition process is modeled into the process of transferring the state of the system from the original state 0 to the state 1, and the question answer retrieval process is modeled into the process of transferring the state from the state 1 to the state 2. The precise and the scope of an answer are guaranteed, and the overall question answering process can be subjected to unified modeling macroscopically. In addition, the target entity transferring process in the question answering process is modeled into the state transferring process in the state machine,a transfer entity is modeled to be in an intermediate state, and a final answer is modeled to be in a termination state. On the basis, the transfer process of all the states achieves decision supporting as a whole through the dynamic programming algorithm, and meanwhile the operation efficiency of the system is guaranteed.

The invention discloses an air conditioner control system and a multi-tube-nest air conditioner. The air conditioner control system comprises an outdoor unit assembly and two or more groups of indoor units. Each group of indoor units communicate with the outdoor unit assembly through a refrigerant pipeline. Confluence pipeline sections of the refrigerant pipelines where the corresponding indoor units are located are provided with throttle valves which are connected in parallel. Check valves are arranged between the refrigerant pipelines where the indoor units are located and the adjacent throttle valve pipelines, and the check valves are used for controlling the corresponding indoor units to be connected with the system to work or not. Intersecting pipeline sections of the refrigerant pipelines of the indoor units are connected with the throttle valves which are connected in parallel. Because the pipelines are connected into the multiple throttle valves in parallel, the controllable adjustment range of flow control amounts to the sum of the control sections of all the throttle valves connected in parallel, and the air conditioner control system can be fully adapted to the work demand that multiple indoor units are connected in parallel; when the number of the working indoor units connected into the system is small, a part of the throttle valves connected in parallel can be directly closed, and only one independent throttle valve is used for connection control; and therefore, the range of the refrigerant flow adjusting area controlled by the throttle valves and the control accuracy are guaranteed.

This refrigerator is provided with: an outer shell body having a storage chamber the front surface of which is open; shelf rails being provided in respective inner wall surfaces of the storage chamber and each extending in a front-and-rear direction; and a front shelf and a rear shelf which are separated from each other in the front-and-rear direction so as to be disposed at the opening side and the deep side of the storage chamber and which are supported on the shelf rails. Claw parts that engage with the shelf rails are provided to respective side edges of the front shelf. In the rear shelf, notches are formed at positions corresponding to the claw parts of the front shelf when the front shelf removed from the shelf rails is stacked on the upper surface of the rear shelf.

The present invention relates to the technical field of target tracking, in particular to a long-distance target tracking system and method based on a long-focus and short-focus camera group. The image is sent to the controller, the controller measures the target coordinates in the target image, the calculation module calculates the movement information of the telephoto camera according to the two coordinates, and the controller allows the telephoto camera to rotate to the target coordinates; the method includes rotating the S1 short-focus camera and Capture the target image and send it to the controller; S2 obtains the target coordinates from the target image, and the calculation module calculates the movement information of the telephoto camera according to the pre-stored initial coordinates and target coordinates; S3 makes the telephoto camera rotate and move the information to the target and capture the tracking image; After the S4 controller obtains the tracking image, it controls the second turntable to reset the telephoto camera. The invention can simultaneously ensure the breadth of the field of view of the shooting target and the clarity of the target.

The invention provides a satellite energy detection cognition method and system based on a radio environment map. The method comprises the following steps that 1, interference caused on a fixed satellite service (FSS) link by a fixed server (FS) link in a satellite-land communication scene is analyzed; 2, according to a spectrum energy detection method, cognition equipment obtains distribution ofdecision counting values of received interference signal energy, and by means of the probability that the decision counting values are larger than a predetermined threshold value, interference information of the cognition equipment is obtained; 3, a geodetic coordinate system of the cognition equipment is converted into a preset navigation coordinate system in an interference area with the GPS cognition equipment to obtain location information (x, y) of the cognition equipment; and 4, the cognition equipment transmits the interference information and the location information to a data center through a control channel not interfered, and the radio environment map is precisely drawn. According to the method and system, idle spectrum resources in the space domain, the frequency domain and thetime domain are reutilized, and the utilization rate of the existing scant radio spectrum resources is increased.

The invention provides a picking route generation method and device. The method comprises the steps that the number of standard cases needed for a wave order is calculated, and a standard case configuration table is generated; a standard case roadway distribution diagram is generated according to the standard case configuration table and a roadway number and a storage location number of goods SKU; a roadway is selected to start picking simulation, and picking simulation information corresponding to the serial number of each standard case is recorded and added into traversed standard case picking information; after picking simulation on the current roadway is completed, the serial numbers of the standard cases where picking is completed form a virtual trolley according to preset rules; if the trolley is successfully formed, whether picking is completed at all standard cases or not is judged, if yes, picking simulation is ended, and if not, the traversed standard case picking information is deleted, and a next roadway is entered to restart picking simulation; and if the trolley is not successfully formed, the next roadway is entered to continue picking. Through the picking route generation method and device, both breadth and precision of picking coverage are guaranteed, and picking efficiency is improved.
