Dispatching management system and method for event emergency response of urban bus passenger transport

The invention relates to a dispatching management system and a method for event emergency response of urban bus passenger transport. Methods of combining actual measurement data, event prediction model and algorithm as well as event real-time dispatching model and algorithm are comprehensively applied; geographical information technology, locating technology and modern communication technology are scientifically integrated; bus emergency dispatching technology developed through bus network intellectualization and multi-way coordinative dispatching technology of an urban bus passenger transport system are utilized; and an emergency coordinative dispatching model and the method are established by taking the networked bus passenger transport vehicle dispatching and operation dispatching management as a core and based on the key theories and methods for multi-way and multi-line intelligent coordinative dispatching of a urban bus and passenger transport system. The invention provides excellent theory, methods and technique supports for the real-time dispatching of urban bus events, effectively reduces the event recognition time, generates a quick real-time dispatching strategy, effectively eliminates the influences generated by the events, and resumes the driving plan so as to effectively improve the running efficiency and safety of buses.

Micro seismic event recognition method based on morphological filtering

The invention provides a micro seismic event recognition method based on morphological filtering. The method comprises the steps of conducting spectral analysis on micro seismic data; rectifying a demodulator used for receiving micro seismic signals; selecting structural elements, combining opening operation and closing operation to form a morphological noise filter, and conducting the morphological filtering on the micro seismic data going through spectral analysis; calculating the energy ratio of a long-time window and a short-time window according to the data going through the morphological filtering, and comparing the energy ratio and triggering threshold to identify whether the demodulator has micro seismic events; and conducting microseism pickup according to the micro seismic events. According to the method, the signal to noise ratio of the data can be improved through preprocessing and further filtering treatment; the micro seismic events can be detected quickly and accurately by utilization of the energy ratio method, the fluctuation type of the micro seismic events can be identified through polarization analysis, and first arrival can be picked up accurately by utilization of self-adaptation threshold and the long-time and short-time window energy ratio method.
