Abstract

The invention, which belongs to the technical field of unmanned automatic guided vehicles, provides a delay power-off control system and method for an unmanned automatic guided vehicle. The system comprises a power switch, a power-off delay relay, a lower computer controller and an upper computer. According to the method, after a power-off signal of the power switch is detected through an IO input, the lower computer controller feeds back the power-off signal, as a shutdown signal, of the power switch to the upper computer via a serial port communicated with the upper computer. When an operator manually turns off the power switch, the system power supply cannot be immediately cut off and will detect the power-off signal; the data are stored automatically by the software and the used computer system is turned off, so that a phenomenon that the system, file, or disk is damaged by the sudden power failure is prevented.

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...
