R

& D direction:

1.

High speed railway operation big data analysis and application;

2.

Urban public transport operation big data analysis and application;

3.

Public transport infrastructure safety operation big data analysis and

application.

Representative

achievements:

1.

Structural state assessment and damage identification of existing bridges based

on monitoring information

The

state extraction, life prediction, structural crack damage identification and

other key technologies of existing bridges are studied. The laws of local

damage and overall performance attenuation of long-span bridges are

established, and the state analysis technology system of existing bridges is

constructed. The safety assessment technology of existing bridges based on

nonlinear chaos theory is proposed, which opens up a new direction of safety

assessment of existing bridges, and establishes several remote bridge

monitoring cluster centers.

2.

Passenger flow analysis, forecast technology and operation of high speed

railway passenger transport big data

To

study the key technologies of multi-source data acquisition and integration,

intelligent analysis and prediction of high-speed rail passenger flow,

intelligent scheduling and optimization of high-speed rail passenger transport,

and travel information service of high-speed rail passengers in the big data

environment, carry out the design of railway passenger transport product

system, and develop the high-speed railway passenger transport big data aided

decision-making information system.

3.

Intelligent heating technology

Taking

thermal energy technology as the center, combining with automatic control

technology, communication technology and network technology, the intelligent

heating system is developed and applied in the fields of transportation, home

heating, industry and agriculture.

4.

Solar power supply technology in low sunshine area

Through

the circuit, algorithm and reasonable system design, the power supply

efficiency of solar photovoltaic power generation under low sunlight conditions

is solved; the dual pulse width control technology is used to improve the solar

energy charging efficiency by 30%; the multi-mode charging technology is used

to maintain the battery activity and significantly improve the service life.
