Abstract

The invention relates to the technical field of engineering machinery, and discloses a safe shutdown method and device, a moment limiter and engineering machinery, and the method comprises the steps:detecting whether the external power supply of equipment is interrupted or not, switching to a standby battery to continue to supply power to the equipment if the external power supply is interrupted,and starting an abnormal shutdown flow of the equipment at the same time. The phenomena of equipment data loss and operating system crash caused by abnormal shutdown can be solved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a safety shutdown method, device, torque limiter and construction machinery. Background technique [0002] In the field of construction machinery, many electronic components that use embedded operating systems, especially electronic components that lack human-computer interaction interfaces, are often switched on and off directly by switches, and the equipment will shut down immediately when it is powered off; There are operations such as reading and writing memory, registers, and file lists. The sudden shutdown of the device will cause some actions that should be completed by continuous operations to be stopped suddenly; it will cause abnormal data. In mild cases, it will cause data abnormalities or loss. It will cause damage to the storage device and file device, cause the operating system to crash, and the device will no longer be able to start normally. [000...
