Data synchronization method of PC (Personnel Computer) end and mobile terminal based on hydraulic polling business

The invention discloses a data synchronization method of a PC (Personnel Computer) end and a mobile terminal based on hydraulic polling business. The data synchronization method mainly comprises two parts of uploading polling data at the mobile terminal and downloading the polling data at the PC end, wherein uploading the polling data at the mobile terminal comprises the following steps of importing polling attribute basic information and multimedia data information in mobile equipment into the PC end, converting the basic data information into data objects through sorting operation of the polling data, storing the data objects in a database and storing multimedia data in a multimedia database to effectively manage the polling data; downloading the polling data at the PC end comprises the following steps of downloading newest hydraulic polling data to the mobile terminal from the PC end to facilitate obtaining result information of last polling when a user carries out polling at each time, and comparing with the current polling site condition to judge the hydraulic safety situation. According to the data synchronization method, the polling data can be automatically, timely and accurately put in storage conveniently, the processing time for the polling data is reduced, and the working efficiency and the accuracy for polling personnel can be improved.
