The technical solution adopted by the present invention to solve the technical problems is：One kind is provided based on satellite-signal to obtain train
Position and the Embedded Solution in direction, it is characterised in that include the following steps：
101st, according to the circuit latitude and longitude information having, interchange of position, station line telephone, interval circuit, switching point position
And circuit debugging phone information is organized into a database；
102nd, host computer increases or deletes circuit, change station line telephone according to demand, and makees corresponding version management；
It 103rd, will be in the NOR Flash memory chips of database copy to hardware system；
104th, miniature MCU obtains the current latitude and longitude information of train from satellite positioning module in real time；According to number in NOR Flash
According to the form in library, station and the station in limited range and information point that lookup train is currently located obtain circuit table；
105th, other application system can be by line name (such as：Hang Shen lines) given line or inquiry previous step in obtain
Circuit table, select a wherein working line as train；
106th, in the case where train operation circuit has determined, if train station in or information point in, basis
