The invention discloses an air spring pressure test overload and overspeed alarm sheme for a magnetic-levitation train, and particularly relates to an overload and overspeed alarm shceme for the magnetic-levitation train. The air spring pressure test overload and overspeed alarm scheme relates to a pressure test device, a speed test device, a process data processing device, a return difference control device, a pressure alarm device and the like. A pressure sensor is arranged in each set of air spring branches, the pressure sensors convert collected pressure into voltage signals, the voltage signals pass through an accumulator, four lines of voltages and a voltage corresponding to unsprung mass of the magnetic-levitation train are added together, and thus a voltage corresponding to single train loading (including self weight) of the magnetic-levitation train is obtained, then the voltage is input into a comparator. The other section of the comparator is a voltage value of a static input end (before starting) or a processed voltage value of a start input end (after starting) after speed signals are infused. A four-door buzzer is chosen to be driven or not according to the output of the comparator, and thus the function of overload alarm is achieved. Therefore, the problems of overload and overspeed of the magnetic-levitation train are solved, and the safety problems of the magnetic-levitation train caused by overload and overspeed are solved. The return difference control device is used for processing zerozone alarm.
