The invention discloses a steering lamp auxiliary control device and method in the vehicle turning process. The steering lamp auxiliary control device comprises a steering lamp switch, a steering wheel angle sensor, a distance sensor, an inertial sensor, a steering lamp controller and a GPS navigation system. The steering lamp switch, the steering wheel angle sensor, the distance sensor, the inertial sensor and the GPS navigation system are all connected with the steering lamp controller. The steering lamp switch is installed below a steering wheel and used for sending a steering lamp turn-on signal to the steering lamp controller. The steering wheel angle sensor is installed in a direction column below the steering wheel and used for obtaining the turning angle of the steering wheel. The distance sensor and the inertial sensor are used for recording the vehicle continuous running distance and measuring the vehicle course. The GPS navigation system is used for detecting the included angle between a road segment where a vehicle is located and a turning road. The steering lamp controller is achieved through a vehicle-mounted ECU and controls the steering lamp to be turned on and off according to information provided by the inertial sensor, the distance sensor, the steering wheel angle sensor and the GPS navigation system.

The invention discloses a system and a method used for producing high purity hydrogen via concentrated-solar-energy-driven high-temperature bubbling-type methane direct pyrolysis. According to the method, collecting lens is used for concentrating of sunlight onto a heat absorber so as to generate a high temperature heat source, a heat carrying fluid is introduced into the heat absorber, and is used for delivering high temperature heat energy into a specially-made bubbling-type reactor; in the specially-made bubbling-type reactor, production of solid state carbon nanoparticles and hydrogen gasis realized via methane direct pyrolysis, the carbon nanoparticles are left in the specially-made bubbling-type reactor and are collected, a mixed gas of hydrogen gas and unreacted methane is delivered into a hydrogen gas separator to obtain high purity hydrogen gas; the heat carrying fluid discharged from the specially-made bubbling-type reactor is relatively high in temperature, so that the heatcarrying fluid is used for generation of high temperature high pressure superheated steam via heating, and driving turbines to produce electricity; generated electricity is used for driving a heat carrying fluid circulation pump and a front booster pump, and the excess electricity is output into a electricity grid. The method is capable of producing high quality carbon nanoparticles, high purityhydrogen, and electricity, and realizing zero carbon discharge, large scale production can be realized; the method is friendly to the environment; and economic benefit is relatively high.

The invention provides an IP positioning database credibility evaluation method based on a dynamic trust model. The method comprises the steps that (1) the consistency of an IP positioning database is analyzed based on the geographical location attribute value; (2) based on the consistency of the current behavior and historical behavior of the IP positioning database, the direct credibility is determined; (3) the indirect credibility of the IP positioning database is determined based on the recommendation credibility of a third-party entity; and (4) the comprehensive credibility is determined based on the direct credibility and the indirect credibility of the IP positioning database. According to the invention, relative objective credibility evaluation of the current domestic mainstream IP positioning database is realized at the provincial level by quantifying the credibility evaluation of the IP positioning database into a dynamic trust model.
