The invention discloses a human-computer chatting method and device based on artificial intelligence. The method includes the following steps of receiving input information input by a user; distributing the input information to chatting service modules; receiving candidate replying returned by the multiple chatting service modules; ranking the to-be-selected replying based on confidence degrees, generating chatting information according to the ranking result, and providing the chatting information for the user. According to the human-computer chatting method and device based on the artificial intelligence, the input information input by the user is received and distributed to the chatting service modules, then the candidate replying returned by the multiple chatting service modules is received, the to-be-selected replying is ranked based on the confidence degrees, and the chatting information is generated according to the ranking result and provided for the user, so that multiple times of chatting with the user can be carried out, the true effect and the natural effect are achieved, initiative is achieved, replying conforming to user styles can be further returned for different users, and the more personalized effect and the more intelligent effect are achieved.

The invention discloses a welding robot control method, and relates to a welding robot control device. According to the welding robot control method, a laser vision sensing system, a laser barcode scanning system, a main industrial personal computer, a driving device and a wireless demonstration device are utilized. A weldment is scanned through the laser bar code scanning system to form a three-dimensional model, the three-dimensional model is led into the main industrial personal computer, and welding information is directly designated on the three-dimensional model through the wireless demonstration device. The welding information comprises positions and lengths of weld joints, and the swing mode of a welding gun. When welding workpieces needs to be produced in a batch mode, a bar code identification system can be used for reading the welding information of welding bar codes on the welding workpieces, then the welding information is sent to the main industrial personal computer, and the main industrial personal computer converts the information of the bar codes into welding signals. The welding robot control method has the advantages that closed-loop control is realized, demonstration efficiency is improved, control of a welding robot is convenient, the electromagnetic field disturbance resistance ability is high, the demonstration efficiency and the quality of the weld joints of the workpieces are improved, the adaptive ability of a control system is enhanced, and the reliability is high.

The application discloses a security baseline system and a method thereof for implementing security checks. Included are that a vulnerability information acquisition unit obtains vulnerability information actively; a linkage processing unit determines a target device based on the obtained vulnerability information, and generates checking information; and a security check unit conducts security checks for the target device based on the generated checking information. According to the application, through the active approach, the security baseline system and the method thereof for implementing the security checks obtain newly discovered vulnerability information positively in an active manner, adapt to the internet field full of such changes, and therefore achieve real-time response to newly discovered vulnerability. Further, by following the customized request of a user, the security baseline system and the method thereof for implementing the security checks establish a user security baseline library, allow the user to customize security rules to conduct security checks for the system, and thus meet the demand that the security checks can be customized.

The invention is applicable to the technical field of communication, and provides a group chat method, a group chat terminal and a server. The group chat method comprises the steps of sending a group chat request to users according to a preset group chat request strategy, establishing a group chat window for users receiving the group chat request, and synchronizing group chat records to the users. The method solves the selection passivity of network group chat members, realizes that users can independently select whether to join group chat according to chat contents and a member list, and ensures that off-line users can not miss shared contents of chat.

The invention discloses an automatic real-time frame synchronization method of a frequency-modulated hydro-acoustic communication system, and relates to hydro-acoustic communication. The automatic real-time frame synchronization method of the frequency-modulated hydro-acoustic communication system comprises the following steps: at a transmitting terminal, sequentially transmitting a coarse synchronizing signal and a fine synchronizing signal both fixed in time length; and at a receiving end, performing sliding FFT (Fast Fourier Transform) on hydro-acoustic signals which are acquired from a transducer terminal in real time by a step size L at first, automatically judging coarse synchronization according to the first-increase and later-reduction trend of a F (f1) value in each spectrogram, calculating the attenuation coefficient a(t) of a channel to signals by using the received coarse synchronizing signal, automatically adjusting a fine synchronization threshold b and estimating the approximate time start c of the fine synchronizing signal, and finally, performing mutual correlation operation on the hydro-acoustic signals acquired from the start c according to the adjusted fine synchronization threshold b to obtain fine synchronization. A DMA (Direct Memory Access) module of a DSP (Digital Signal Processor) is used for setting a ping-pong buffer in which the hydro-acoustic signals acquired by an AD (Acquisition Device) can be stored without DSP intervention; as a result, automatic real-time tracking on synchronizing signals in up-and-down hydro-acoustic channels is realized; the quantity of operation is low and few memory resources are occupied.

A regulating method for a water attack resisting open and close valve is used in the field of oil field oil production and mechanical flow delivery. The invention is an active protection water attack measures, sets the opening and closing program of the open and close valve, i. e. slow initialization opening and closing under the condition that the open and close action time of the open and close valve is definite to lead fluctuation generated from the forward wave and the reflected wave of the water attack not to develop completely and prevent the direct water attack under a certain open amount. In the opening later period, the opening speed is high, four times to the initialization speed. The pressure variation is mostly the mutual effect of the water attack wave and the water attack reflected wave. The opening amount variation has less effect to the initialization speed and the water attack wave amplitude. Therefore, the rise value of the water attack pressure in the system is minimum or less than prescribed value so as to facilitate to reduce the systemic responsive time. The water attack protection method can actively prevent the water attack destruction, reduce the preventive measures, saves construction cost and has a low cost and small land occupation and a perfect pressure-limiting effect.
