The present invention discloses an asymmetrical PN junction thermoelectric couple structure and its parameter determination method. By changing the structural parameters of p-type semiconductor or n-type semiconductor, the current generated by p-type semiconductor is equal to the current generated by the n-type semiconductor, so that the high-efficiency output of PN junction thermoelectric couple can be realized. Meanwhile, the present invention provides a method for determining the parameters of PN junction based on the numerical solution method. Finally, the optimal size parameters of PN junction are obtained.

A method for constructing an active magnetic bearing controller based on a look-up table method includes: building finite element models of an active magnetic bearing to obtain two universal Kriging prediction models in X-axis and Y-axis directions about actual suspension forces being in association with actual displacement eccentricities and actual control currents in the X-axis and Y-axis directions of the active magnetic bearing based on a universal Kriging model; creating two model state tables in the X-axis and Y-axis directions about the actual suspension forces being in association with the actual displacement eccentricities and the actual control currents to construct two look-up table modules with the two built-in model state tables, respectively; and constructing an active magnetic bearing controller by using two fuzzy adaptive PID controllers, two amplifier modules in the X-axis and Y-axis directions, the two look-up table modules, and two measurement modules in the X-axis and Y-axis directions.

A driving service active sensing system and method in an Internet of Vehicles environment in the field of road traffic safety. A sensor device and an intelligent vehicle-mounted terminal arranged on a vehicle and connected to each other. The intelligent vehicle-mounted terminal communicates with roadside equipment in 4G and DSRC modes, and communicates with a driving service information processing center in 4G mode. The roadside equipment communicates with the driving service information processing center in 4G mode. The roadside equipment is provided on both sides of a road. The sensor device outputs obtained vehicle traveling information to the intelligent vehicle-mounted terminal, which processes and integrates the received vehicle traveling information and then transfers integrated information to the roadside equipment and the driving service information processing center. A driving service cloud computing platform processes the integrated information and outputs driving service information to the roadside equipment and the intelligent vehicle-mounted terminal.
