Adopt centralized control method: to realize visual management, all AGVs can be monitored in real time in the dispatching system and can be manually adjusted (to meet different station material calls). Realize the following main functions:
Task management: Scheduling tasks issued by the task management computer according to time sequence and task priority.
Execution environment: schedule AGV operation according to task priority and start time ; provide status monitoring of AGV and various operations of tasks, such as: start, stop, cancel, etc.
Multiple AGV status monitoring;
Vehicle management: According to the position and state of the AGV at that time , select the idle AGV closest to the target point (including the weighted value calculation results of each road segment) to perform the task; monitor the state of the AGV 's power and let the AGV charge when needed .
Charging control and monitoring: real-time display of AGV power and charging status
Traffic control: real-time control and management of all AGVs in the jurisdiction . AGV strictly follows the planned route, drives and works independently of each other, and can give each other cars.
Communication management: The AGV ground control system computer keeps in touch with the task management computer via Ethernet. Accept task scheduling and report execution results; AGV ground control system computer maintains real-time communication with each AGV through a wireless local area network to direct vehicle operations and obtain various vehicle statuses. The wireless network is based on the IEEE 802.11 standard and uses a 2.4GH frequency It can be used without applying to the Radio Management Committee; the AGV ground control system computer is converted to digital I / O module communication through the serial communication port , collects various external signals, and processes various states, such as intelligent charger Automatic door system, etc.
Information collection / report management: generate a list of scheduling tasks for each site, can see the information of various materials acceptance and delivery time, etc .; can initially analyze the possible congestion risk, and can be manually eliminated in time.
