Abstract

The invention provides a delay power-off control system and method for an unmanned automatic guided vehicle, belonging to the technical field of unmanned automatic guided vehicles. The system comprises a power switch, a power-off delay relay, a lower computer controller, and an upper computer computer; In this method, after the power-off signal of the power switch is detected through the IO input, the controller of the lower computer feeds back the power-off signal of the power switch as a shutdown signal to the computer of the upper computer through the serial port connected to the computer of the upper computer; when the operator manually turns off the power switch , the system power will not be cut off immediately, the system will detect the power failure signal, automatically save the data through the software and shut down the computer system used to prevent the system, files or disks from being damaged due to sudden power failure.

Description

technical field [0001] The invention belongs to the technical field of unmanned automatic transport vehicles and relates to an AGV electrical control system. Background technique [0002] AGV is an unmanned automatic transfer vehicle powered by lead-acid or lithium batteries. Its control system usually includes motion control and upper-level task logic decision-making. Usually, motion control is completed in an embedded system or a lower-level computer controller such as PLC. , the upper decision-making is developed in the host computer. When the operator turns off the AGV switch to cut off the battery power, the AGV system will suddenly lose power, which will easily cause damage to the computer software, system or disk developed by the upper layer. Contents of the invention [0003] The present invention proposes an AGV (unmanned automatic transport vehicle) delayed power-off system and method, and designs a power-off delay circuit. When the operator turns off the batter...
