Abstract
The invention provides a real-time data ground mapping method and a system thereof, relating to the field of computer application. The method comprises the following steps that: a client based on a B/S mode periodically sends a querying request to a server, receives operation data returned by a query database after the server responds to the request, and maps the received operation data by using the dynamic mapping technology, wherein when the operation data in the database is locomotive real-time operation data which is acquired by vehicular equipment according to a preset cycle and is received by a ground management center, the received real-time operation data is analyzed and added into a server database. The system comprises the vehicular equipment, the ground management center, the client and the server. The system does not require installing specific client software, users can use the software freely in an arbitrary region and on a computer accessing to the Internet; system updating only requires updating the server software so as to avoid complexity of client maintenance and greatly promote user experience.
