The invention provides a moving emission platform bend walking differential control system. The control system comprises a moving emission platform, rolling wheel bodies arranged below the moving emission platform, and rails for supporting the rolling wheel bodies. The moving emission platform is provided with four bend detection sensors. The rolling wheel bodies are connected with a drive motor connected with a frequency converter. The frequency converter is connected with a PLC. Induction heads of the bend detection sensors are arranged at the positions, close to the rails, below the emission platform. The bend detection sensors are connected with the PLC. Induction magnets are arranged on bends of the rails. The moving emission platform bend walking differential control system ensures that a plurality of forms of complex operation of the bends and differential of the moving emission platform can be achieved; moreover, in the operating process, it is ensured that transfer tasks can be finished within the stipulated time, and the stability and the reliability of carrier rockets on the upper portion of the moving emission platform can be ensured.
