Problems solved by technology
[0018] also, both operational control units and automated guided vehicles require communications processing, necessitating investment in software development for them
[0019] Also, in order to achieve higher communication efficiency, the software-related structure for communication processing must be changed to a high-speed processing polling system, a competing communication system or the like, and this will disadvantageously lead to more complex structure
[0020] In addition, when the content of communication is changed, the communication protocol and communication processing need to be modified or increased

Embodiment Construction
[0064] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[0065]FIG. 1 is a schematic structural diagram of relevant parts of an automated guided vehicle 1 according to an embodiment of the present invention. In Fig. 1, 11 is a wireless local area network adapter (hereinafter referred to as a wireless LAN adapter) connected to a local area network, which is used to communicate with a factory host, an operation control unit, an external device including a network computer, or other automatic guided vehicles 1 by radio. Send message. Among them, 16 denotes an antenna connected to the wireless LAN adapter.
[0066] 12 is a storage section, which stores driving data, information related to transportation, information about start instructions, status data of the automatic guided vehicle itself (for example, encountered difficulties, in transportation, in transfer, stopped, loading , under manual control, wa...

A waiting time of an automated guided vehicle is substantially eliminated by significantly shortening the communication time of various information, and the transport efficiency of an automated guided vehicle as well as the operating rate of work stations and production lines as a whole are improved, and in addition, the flexibility of an operation control system for the automated guided vehicle is improved. An automated guided vehicle 1 includes a wireless local area network adapter 11 for passing information by radio with an operation control unit connected to the local area network or with another automated guided vehicle, a memory part 12 for storing at least information from the operation control unit or from another automated guided vehicle and information related to the automated guided vehicle itself, and a control part 14 for controlling the wireless local area network adapter and the memory part.
Description
technical field [0001] The present invention relates to a plurality of automated guided vehicles or automated vehicles with self-propelling capabilities, and operational control systems and methods for these vehicles. In particular, the present invention relates to a technique for transmitting information between a plurality of automated guided vehicles and their control units, and between a plurality of automated guided vehicles. Background technique [0002] Traditionally, for driving control of an automated guided vehicle in an automated guided vehicle system aimed at achieving automation and labor saving, it is common to use a guidance system with a fixed route without a trajectory, which appears to be cost and technically advantageous. Such a fixed route is determined by a guide line, such as a guide tape attached to the floor of an unmanned warehouse or factory. An autonomous guided vehicle automatically travels along a guide line while detecting the guide line either...
