The invention provides a train speed limit curve calculation method and device for a moving block system, and the method comprises the steps: obtaining a speed limit look-up table corresponding to a current train in a periodic operation stage; determining effective wind pressure according to the pipe wind pressure and the tail pressure of the current train; under the condition that the current train meets the limiting condition, obtaining the obstacle speed limit and the temporary speed limit within the MA terminal point or the front first preset distance range; according to the MA terminal point or a first preset distance range in front and the position of the current train, sequentially determining multiple speed limiting points, querying a speed limiting query table according to the effective wind pressure, and obtaining the speed limiting of the multiple speed limiting points; and obtaining a speed limit curve of the current train according to the obstacle speed limit, the temporary speed limit and the speed limits corresponding to the plurality of speed limit points. According to the method, calculation during periodic operation is changed into inquiry, the occupied periodic operation time can be shortened, the speed limit curve calculation efficiency is improved, and therefore safe running of the rail transit train is facilitated.
