Rolling force measuring system with overload measuring function

The invention provides a rolling force measuring system with an overload measuring function, and relates to the technical field of rolling. The system comprises a rolling force sensor and a secondary instrument, wherein the secondary instrument comprises an excitation power supply, a first calculation channel, a first signal output end, a second calculation channel and a second signal output end; the excitation power supply is electrically connected with the rolling force sensor; the signal output end of the rolling force sensor is connected with the first calculation channel and the second calculation channel. The first calculation channel is used for calculating a first load force value according to pre-acquired first calibration data; the second calculation channel is used for calculating a second load force value according to pre-obtained second calibration data. According to the system, the secondary instrument with the two calculation channels is adopted, calibration data for different rolling force ran
