Information interaction method of PMS and mapping module

The invention relates to an information interaction method, which can effectively meet the information interaction requirement between a PMS (Power Management system) and a mapping module and has the characteristic of simple flow process. The information interaction method has the technical scheme that 1, the information interaction method of the PMS and the mapping module is characterized by comprising the following steps that: (1) the PMS pushes transaction flow process data starting service to the mapping module; (2) the PMS pushes the changed route and plant-station information to the mapping module; (3) the mapping module sequentially requests model data to the PMS according to the route and plant-station information; and (4) after all route and plant-station model data is completely requested, the mapping module pushes transaction flow process data processing state service to the PMS, and notifies the PMS of the current transaction data processing result; if the processing is successful, an automatic mapping client can be called for mapping; and if an error is found in the processing process, the mapping module sends error information to the PMS, and waits for the PMS to send a model again.
