Abstract: Disclosed are a non-to-the-home type device and method for detecting electric meter misconnection based on the PLC communication technology and using multiple frequencies. The detection device includes a master detection device and a slave detection device. The master detection device acquires address information of different electric meters at the outlet terminals of the electric meters by using RS485 communication. The modulation circuit modulates the communication address information of different electric meters into high-frequency carrier signals of different frequencies, and sends the high-frequency carrier signals to user sides by using the PLC communication technology. A line trap is provided between the modulation circuit and the electric meters. The slave detection device has a high-frequency carrier signal detection antenna.

Abstract: A summary obtaining method includes obtaining a target document from which a summary is to be obtained; dividing the target document into sentences and dividing each sentence into words; and obtaining a classifier constructed based on a long short-term memory (LSTM) model. The classifier comprises a word-level LSTM layer configured to determine a vector of each sentence according to the words in each sentence, and a sentence-level LSTM layer configured to determine a vector of the target document according to the vector of each sentence. The method further includes determining, by using the classifier, a probability that each sentence is a summary sentence, according to the vector of the target document and a vector of the sentence; and determining a sentence with the probability satisfying a predetermined condition for a summary sentence, as a summary sentence of the target document, and forming the summary according to the summary sentence.

Abstract: The present invention provides a type of cost-effective sulfur-based transition metal composite as the negative electrode active material for lithium ion batteries with high capacity. Moreover, a non-aqueous secondary battery using this negative electrode with long cycle life and high capacity is provided. The battery contains a positive electrode, negative electrode, separator, and non-aqueous electrolytes. The negative electrode contains at least one kind of sulfur-based transition metal composites provided in the present invention.
