In order to ensure the normal operation and maintenance of rail transit, the role of command and dispatching system is particularly important. Therefore, the application of urban rail transit emergency dispatching command system mainly uses information technology to improve emergencies, improve the efficiency of traffic dispatching command emergency disposal and emergency response.

　　(4) Electric power

　　Sufficient stability of the electric power supply, a direct impact on the operation of the social economy development and people's life, happiness must depend on the mature and stable modern specialized electric power dispatching command and control system, this system includes power grid scheduling command center, power production command center, power monitoring center, electricity trading center, etc., It is responsible for real-time monitoring of power grid data, issuing of power production orders, dispatching of power grid operation, handling of emergencies and other important functions.
