Abstract: Provided are an anomaly detection method and electronic device, applied to a network security device. An instruction parsing process is performed on industrial network traffic generated by executing a configured production procedure in an OT network, to obtain control instructions sequentially issued by each industrial device to perform a corresponding abstract-behavior-switching during executing the production procedure. A target control instruction set constituted for each industrial device based on obtained control instructions is matched with a pre-established control instruction feature library. The control instruction feature library includes control instruction feature sets constituted by control instructions issued by each industrial device for various abstract-behavior-switching. If the matching succeeds, it is determined that no anomaly exists in the abstract-behavior-switching performed by the industrial device during executing the production procedure.

Abstract: An intelligent service system includes: a proxy server, where the proxy server has a user session channel established between the proxy server and a user requesting a service, and assigns a session identifier to the user session channel; and the proxy server has one or more service session channel established between the proxy server and an external AI server; the proxy server is to receive a service request from the user through the session channel; and in the event that the user authentication passes, the session identifier corresponding to the user and the request content in the service request are sent to the AI server through any of the one or more service session channel.

Abstract: A method for micro-ridge mixed-sowing cultivation of rice includes: S1: draining away water at the maturity stage of the preceding crop until reaching a state allowing a harvester to operate; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble to form a rhizosphere layer for rice growth; S3: trenching the field to form ecological trenches; S4: flattening the standing stubble and the smashed stalks on the seedbed surface to form an underlying surface, molding seed-fertilizer-soil compounds into a ridge shape and fall the seed-fertilizer-soil compounds on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, and the seed-fertilizer-soil compounds are obtained by thoroughly mixing rice seeds, chemical fertilizers and soil at a mass ratio of 6 to 14:50 to 70:6,000 to 10,000.

Abstract: A method for micro-ridge mixed-sowing cultivation of dryland crops includes the following steps: S1: cleaning ditches and draining away water in dryland; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble; S3: trenching the dryland to form ecological trenches; S4: flattening the standing stubble and the smashed stalks on the seedbed surface to form an underlying surface, molding seed-fertilizer-soil compounds into a ridge shape and allowing the seed-fertilizer-soil compounds to fall on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, an ecological depression is formed between adjacent ecological ridges, and after sowing, an irrigation is carried out, including: draining water shortly after the irrigation, without leaving a water layer in the field.
