The invention provides a transponder message temporary speed limit inverse solution verification method and system for train control software. The method comprises the following steps: obtaining and storing a message, and descrambling to obtain the temporary speed limit information of the message; performing information traversal to obtain a line data set corresponding to the temporary speed limit of the message; judging whether the message temporary speed limit information and the first block partition matching set have an overlapping region or not, and obtaining a first identification result; obtaining a first traversal result; when an overlapping region exists between the first traversal result and the first block partition matching set, obtaining a second identification result; and performing verification through the first identification result and the second identification result. The technical problems that in the prior art, the complexity of a railway transportation operation scene is high, the safety verification capability of a key system output result is weak, the operation amount and the operation complexity are high due to verification logic, the dependence on the operation performance of a hardware platform is high, and the safety of system output is low are solved.
