Control method for full-width electric emergency safety device of low-floor modern tramcar

The invention relates to the field of rail vehicle expansion type ramp detection, in particular to a control method of a low-floor modern tramcar full-width type electric emergency safety device, which comprises the following steps: S1, opening an expansion type ramp; s2, a detection device is started; S3, if the joint between the unfolded ramp and the ramp recovery mechanism has no problem, the detection device is started; s31, the detection device is reset; S3, if the joint between the unfolded ramp and the ramp recovery mechanism has no problem, the detection device is reset; s32, the detection device enables a connecting piece for connecting the unfolded ramp and the ramp recovery mechanism to return to a preset position; and S33, manual maintenance is carried out. By effectively utilizing the structural configuration of the device, the advantages that the detection is convenient and fast, the detection device can play a role in supporting the expanded ramp in a short time, and the joint of the expanded r
