The present invention provides a vehicle full life circle electrical performance monitoring assessment system and method, belonging to the vehicle intelligent device field. The technical scheme of the method comprises: a central control unit is connected with a data collection unit and a network transmission unit; and a vehicle electrical state integration assessment unit is connected with a sensor data storage analysis unit, an electrical state model depth learning unit, a fault code storage analysis unit and a vehicle electrical state historical recording unit. The vehicle full life circle electrical performance monitoring assessment system and method perform comprehensive monitoring and assessment of electrical performances of a vehicle to obtain a more scientific assessment result in the used-car transaction process, when car insurance flexible pricing, when the assessment of vehicles through a vehicle management relevant departments and when vehicles are discarded so as to ensure the consumers' benefit, improve the management efficiency of the vehicle management departments and save the resource to reach cyclic utilization.

The invention discloses a comprehensive assessment method based on the effect of a distribution type electrical connection on a power distribution network. The comprehensive assessment method is characterized in that a comprehensive assessment index system of the effect of the distribution type electrical connection on the power distribution network, three-level index values under different distribution type electrical connection schemes are worked out by analyzing the power distribution network including a distribution type power source, a standard decision matrix of an assessment index is established, the weight coefficients of a one-level index, a two-level index and a three-level index are respectively obtained, accordingly, the comprehensive weight coefficient is determined, the comprehensive assessment satisfaction degrees of different distribution type electrical connection schemes are finally worked out, and the scheme with the largest comprehensive assessment satisfaction degree serves as the optimal distribution type electrical connection scheme. The comprehensive assessment method avoids the insufficient data information amount probably occurring through the single utilization of the object analysis method and also avoids the subject randomness of direct utilization the subject analysis method, and complex links of detecting and judging the matrix consistency are reduced while the judging fuzziness of people is taken into consideration.

A method based on the combination of pictures and texts to evaluate the mental state, which evaluates the user's mental state by analyzing the user's historical psychological text and image number per unit time, obtains the user's real mental state, and timely feedbacks the evaluation results and corresponding Countermeasures and suggestions enable users to intuitively understand their current psychological state, which is convenient for users to make self-adjustment or seek medical treatment in time to achieve a state of mental health.

The present invention disclosed a maintenance analysis method based on the BIM and GIS -based channel rectification buildings. This method uses BIM technology and GIS technology to integrate the monitoring results in the preliminary design and maintenance process of channel rectification buildings, which is conducive to rectifying the damage analysis of buildings.The evolution of the riverbed evolution and the evaluation and analysis of the building, and realize the comprehensive display of the three -dimensional visualization platform, system analysis and repair solutions of the three -dimensional visualization platform of channel remediation buildings to provide effective means for the maintenance management of channel rectification buildings.

The invention provides a thunder and lightning information collection and early warning system for a high speed railway. The system comprises a thunder and lightning information collection device, a current signal / value signal conversion device, a device for dynamically generating a reference threshold of thunder and lightning disaster risks, a determining device startd by an early warning program, a locating device, a train controlling device for controlling the speed of a train, a storage device and a control device. A control module serves as a core of the whole system, controls operation of the devices on one hand, and is used for being connected with external devices including an external computer device and the like to achieve communication and control. In the system, the dynamic generating mode is adopted in the reference threshold for evaluating the thunder and lightning disaster risks, the historical disaster situations are combined, and the historical situations are continuously updated after new early warning is given, so that the risk pre-evaluation of a certain region is considered more completely and scientifically with contrast to historical data. The invention further provides a thunder and lightning information collection and early warning method for the high speed railway.

The present invention provides a high-speed railway seismic data information collection and early warning system, including a seismic fluctuation information collection device, a current signal / numerical signal conversion device, a device for dynamically generating a reference threshold for earthquake disaster risk, a decision device for starting an early warning program, The positioning device, the vehicle control device for controlling the speed of the train, the storage device, and the control device. The control module is the core of the entire system. On the one hand, it controls the operation of the aforementioned devices. Connections enable communication and control. In the present invention, the reference threshold for earthquake disaster risk assessment is dynamically generated, combined with historical disaster occurrences, and the historical situation is continuously updated after the latest early warning occurs, so that it can be compared with historical data to achieve a more complete and scientific Consider a pre-assessment of risk in an area. The invention also provides a high-speed railway seismic data information collection and early warning method.

The invention relates to a power quality comprehensive evaluation system in the technical field of the electric power application; in the invention, a power quality collecting module obtains all items of power quality indexes from an electric fence; a power quality index grading module divides the power quality indexes obtained from the power quality collecting module into setting grades according to national standard or international generally recognized requirements; a probability distribution matrix obtaining module obtains probability of the power quality in each grade, and then the probability of the power quality index in each grade is obtained for obtaining a probability distribution matrix; a weight vector obtaining module obtains weight vector of the power quality index; an evaluation quantized value obtaining module obtains the only quantized value of the power quality comprehensive evaluation according to the probability distribution matrix and the weight vectors of all theindexes; a power quality evaluation module compares the only quantized value with the evaluation system for obtaining power quality evaluation result. The system can really reflect the probability characteristics of the power quality indexes and can comprehensively and objectively carry out comprehensive evaluation to the power quality.
