A kind of hydrate method cold accumulation and cooling system based on LNG cold energy, including gas supply system, hydrate method cold accumulation system, cooling system and refrigerating unit auxiliary system.The huge cold energy released in LNG gasification is used in gas supply system by deionized water and resident building return water coolant water in turn.The absorbed LNG cold energy is accumulated in hydrate method cold accumulation system, and the cold accumulation system can separate hydrate and deionized water, and can realize variable rate cold accumulation.The coolant water in cooling system exchanges heat with LNG and hydrate slurry in turn, and is sent to cold storage and resident building user by circulating pump pressurization, when the cooled coolant water cannot meet the requirement of cold energy demand end or cooling system cannot stably cool, refrigerating unit auxiliary system is opened, the opening of distribution valve is adjusted according to the temperature of cold energy demand end, the coolant water through distribution valve and the coolant water without distribution valve are mixed in mixer, to meet the cold energy demand of demand end.The system has the advantages of energy saving, sustainable and stable cooling, and has the value of commercial application.

The application discloses a sound source orientation method and device, a sound source separation and tracking method and a chip, and aims at solving the technical problems of complex calculation, poor anti-interference and difficulty in hardware implementation of the existing sound source orientation method. The application obtains a pulse signal of the sound source data to be processed by performing zero-crossing pulse coding on the sound source data to be processed. Direction estimation is performed on the pulse signal obtained through the zero-crossing pulse coding based on a pulse neural network, so that the target sound source direction of the sound source data to be processed is obtained. The method is simple, has good real-time performance and low cost, can be easily implemented in a low-power hardware, and the chip test result is almost consistent with the computer simulation result, so that the method has commercial application value. The application is suitable for the field of brain-like computing.
