The invention relates to a railway signal safety calculation method and device and a safety computer platform. The method comprises the following steps of: performing forward calculation on data input according to a basic processing flow in the railway signal control system through a forward calculation module to obtain a forward calculation result of the data input, receiving the forward calculation result through a reverse calculation module connected with the forward calculation module, and performing reverse calculation on the forward calculation result to obtain a reverse calculation result of the data input; and obtaining a reverse calculation result, so that the railway signal safety calculation device can compare the reverse calculation result with data input according to the reverse calculation result and the data input from the outside of the system or other units, and can calculate the safety of the railway signal according to the consistency and difference of the reverse calculation result and the data input. The problem of heterogeneity of safety redundancy comparison can be mainly solved, common cause failure is avoided as much as possible, and safety is improved.
