Rail car operation safety control system and method

The invention discloses a rail car operation safety control system and method. Two safety control modules are adopted, each safety control module is provided with two MCUs, a first MCU receives a first acquisition signal and receives a processed second acquisition signal sent by the second MCU at the same time, the processed first acquisition signal is compared with the processed second acquisition signal, and a first emergency braking judgment result is obtained; the first emergency braking judgment result is transmitted to the safety execution unit; and a second MCU receives the second acquisition signal, receives the processed first acquisition signal sent by the first MCU at the same time, compares the processed second acquisition signal with the processed first acquisition signal to obtain a second emergency braking judgment result, and transmits the second emergency braking judgment result to the safety execution unit. The reliability of the host control car can be improved, and the safety of the rail c
