The invention discloses a wheel tread damage testing device. The wheel tread damage testing device comprises a simulation mechanism, a driving mechanism and a braking mechanism; a wheel sample is abutted with a steel rail wheel; the rolling contact between a wheel set and an iron rail can be simulated; the wheel sample is mounted on a wheel axle in a sleeving mode and is in key connection with thewheel axle; a loading seat is arranged on the wheel axle; and a conical roller bearing and a thrust ball bearing are arranged between the loading seat and the wheel axle. A loading plate arranged onthe loading seat can be used for simultaneously loading a transverse wind load and axle weight for the wheel sample, so that the rolling contact abrasion and the fatigue damage of wheel treads when the train wheel set bears the axle weight and the wind load at the same time in a high-speed rotating state are simulated; and then the tread damage is detected, so that effective prevention measures can be made subsequently.

The invention relates to a method for evaluating the overall health degree of an information system based on big data analysis, belonging to the information technology field. The method comprises thefollowing steps: step S11, acquiring state indexes and performance indexes of various resources in the information system, calculating resource state index scores, resource performance index scores and overall usability index scores of the information system, wherein the overall usability index score of information system is based on the resource status index score; S12, calculating the overall health degree of the information system based on the resource state index score, the resource performance index score and the overall availability index score of the information system. The invention solves the problem that the information system in the prior art has no overall health degree analysis and research and judgment, realizes real-time tracking of the overall health degree of the information system, realizes automatic early warning and research and judgment of the information system by means of the quantitative health degree index before the system performance is lowered and the faultoccurs, and ensures the safety, stability and efficient operation of the information system itself.

The invention discloses a battery, a mobile terminal and a large-current automatic cutout method therefor. The mobile terminal comprises a main board and the battery; when the battery detects current exceeding a preset threshold, the battery cuts off of power supply to enable the main board to shutdowns, so that the battery and the main board are protected, and effective preventive measures on short circuits of the battery are realized; the battery restores to supply power after the first preset time to ensure normal starting up next time; the main board detects whether the battery outputs voltage sequence or not in starting up, if so, the main board judges whether the obtained voltage sequence is the same as a pre-stored sequence or not, if so, the main board prompts a user that the shutdown of last time is abnormal, so that the abnormal condition of the mobile terminal can be prompted.

The invention discloses a vehicle regulating and controlling method of lowering a probability of traffic accidents of different severity. The method includes the steps: (10) obtaining traffic information of an accident road section; (20) collecting traffic data of the accident road section before accidents happen; (30) collecting the traffic data of the accident road section in a normal state; (40) setting up a traffic flow data sample; (50) setting up a probability function of the traffic accidents of three stages after standardization; (60) measuring and calculating the probability of occurrence of the traffic accidents of the different severity; (70) measuring and calculating a probability threshold value of the traffic accidents of the different severity; (80) detecting the probability of the traffic accidents of the different severity of the road section in real time, and regulating and controlling vehicles; and (90) repeating the step (80), carrying out detection on the probability of the traffic accidents on the road section in following set time T, and regulating and controlling the vehicles until the detection is finished. The vehicle regulating and controlling method detects the probability of the traffic accidents of the different severity in real time, regulates and controls the vehicles, and improves driving safety.

The invention discloses a power system steady-state tidal current risk identification and prevention method, storage medium and equipment, based on historical wind speed, light intensity prediction data and actual data sets, and the power characteristic curve of the new energy unit, to predict the output of the new energy unit Probabilistic modeling of the error; according to the real-time forecast value of the current new energy unit output, the probability distribution expression of the corresponding forecast error is obtained, and the semi-invariant method is used for stochastic power flow calculation to obtain the probability distribution of each node voltage and branch power; according to Probability distribution sets the threshold to judge whether there is a risk of voltage and power flow crossing the boundary at the time of prediction. If there is no risk, the calculation will be carried out at the next moment. risk so far. The invention can accurately and efficiently identify the region and degree of the steady-state power flow risk of the power system, provide risk prevention measures, and improve the safe and stable operation capability of the power system.
