The invention belongs to the technical field of elevator safety design, and discloses an automatic top digging rope supply system. The automatic top digging rope supply system comprises a dropping protection controller, a power source, a gravitational acceleration sensor, a wireless signal alarm, a stress sensor, a wiring harness, a pedal, high-pressure springs, a first-aid kit and a digging rope box. The dropping protection controller, the power source, the gravitational acceleration sensor and the wireless signal alarm are sequentially arranged on the upper surface of the top of a lift car. The stress sensor is arranged on the lower surface of the top of the lift car. The pedal is arranged at the bottom of the lift car. The high-pressure springs are arranged between the pedal and the lower bottom face of the lift car. According to the automatic top digging rope supply system, when the dropping protection controller monitors dropping of the lift car through the gravitational acceleration sensor, the wireless signal alarm is controlled to be started, and rescue workers are informed of arrival in time. The automatic top digging rope supply system is reasonable in design, simple in structure and suitable for optimization design of vertical elevator dropping loss-reducing systems.
