The invention provides a multi-data triple modular redundancy judgment module based on an FPGA (Field Programmable Gate Array). Three data registers of a preceding-stage working system are combined two by two and divided into three groups, each group of data registers is connected with two input ends of one data comparator respectively, and the output ends of the three data comparators are combined two by two and are then input into the control ends of two multi-channel data selectors simultaneously, wherein three data input ends of one multi-channel data selector are connected with the three data registers of the preceding-stage working system respectively, an output of the multi-channel data selector is correct data output of the judgment module, and the other multi-channel data selector outputs error report signals when the preceding-stage working system has a fault. The multi-data triple modular redundancy judgment module based on the FPGA not only can achieve the purpose of acquiring correct data through triple modular redundancy judgment by multi-digit data simultaneously, but also judges whether a system fault happens and from which module do the wrong data come.
