Risk evaluation system based on urban gas pipeline design

The invention discloses a risk evaluation system based on urban gas pipeline design. The system comprises a central processing unit, a pipeline information integration module, an equal ratio amplification module, a coordinate area circle selection module, a population integration analysis module, a diffusivity distribution module, a pipeline coordinate integration modeling evaluation module, a fault rate evaluation module, and a construction factor evaluation module. The central processing unit is in communication connection with the pipeline information integration module, the equal-ratio amplification module, the coordinate area circle selection module, the population integration analysis module and the diffusivity distribution module. The system has the beneficial effects that basic comprehensive modeling is carried out on statistical distribution of communication population, region and diffusivity of pipeline design based on urban gas planning, and risk coefficient comparison is carried out in cooperation
