Dynamic checking method of intelligent substation IED (intelligent electronic device) model configuration correctness based on SCD (security coding device) files

The invention discloses a dynamic checking method of intelligent substation IED (intelligent electronic device) model configuration correctness based on SCD (security coding device) files. The dynamic checking method is adaptable to a digital substation or an intelligent substation communicated under IEC61850. The dynamic checking method includes firstly extracting relative IED model information to be detected from the SCD files, then mapping the relative IED model information to be detected into MMS (multimedia messaging service) named variables, and storing the MMS named variables as a data file 1; then communicating with the IED to be detected in a client terminal mode, reading information of each layer of the IED to be detected online through ACSI (abstract communication service interface) model reading service, and storing the information as a data file 2; and finally comparing the model information of the data file 1 to that of the data file 2 to determine whether the model information is identical or not. The dynamic checking method has the advantages that downloaded CID (character identifier) files in the intelligent substation IED and the SCD file information are checked automatically to determine whether the information is identical or not.

Sparse point cloud multi-target tracking method fusing spatio-temporal information

The invention provides a sparse point cloud multi-target tracking method fusing spatio-temporal information, and belongs to the field of 3D vision. According to the method, the point cloud feature extraction network is used as a trunk, multiple frames of point cloud data are input at the same time, time domain information fusion is carried out on extracted features, and therefore missing detectioncaused by point cloud sparseness is avoided. Benefited from the fusion of time-space information, tracking and detection tasks can be more tightly coupled, and detection frames of three frames beforeand after can be predicted at the same time to obtain a track segment of a current target for three continuous frames. Then a distance intersection ratio score of the current trajectory segment and the trajectory tracking result at the previous moment is calculated, and the currently split trajectory segment and the historical trajectory segment are matched and spliced by using a greedy algorithmto obtain a final trajectory tracking result at each moment. The method has the application potential of coping with multi-target tracking under sparse point clouds, has high robustness for target missing detection and false detection, and can still obtain a stable tracking result in sparse point cloud sequence input.

The invention relates to the field of livestock production and discloses a self-cleaning type bowl for cows to drink water. The self-cleaning type bowl for cows to drink water is characterized by being composed of a water control valve, a water bowl with water leaking holes and a water leakage control system. The water control valve is composed of a water inlet 1, a valve sheet 2 and a pressing plate 4. The water bowl with water leaking holes is composed of a water bowl body 5, a perforaled strainer 6 and the water leaking holes 7. The water leakage control system is composed of moving and fixed contacts 3, a controller 9 and an electromagnetic valve 8. Under the control of the water leakage control system, the water bowl stores water when the cows drink water and leaks water when the cows do not drink water. Residual water and concentrate residues in the water bowl are leaked out, only a little water can be evaporated rapidly, and only some fiber feed residues are remained so as to enable the water bowl to maintain states of water deficiency and nutritional deficiency whichrestrain growth and reproduction of microorganism and guarantee that the cows cannot drink metamorphic water. The self-cleaning type bowl for cows to drink water achieves self-cleaning functions after the cows drink water, artificial cleaning is convenient, and drinking water quality of the cows is improved greatly.
