Gateway devices and wireless control network management system using the same

摘要

An object of the invention is to improve the reliability of a wireless control network management system. Gateway devices (2 and 3) for relaying data communication between a monitoring/controlling host (1) connected thereto via a wired network and a plurality of wireless nodes (41 to 48) connected thereto via wireless circuit and constituting a wireless network, wherein the gateway device (2 or 3) comprises wireless communication means (21) for sending data from the host (1) to at least any one of the wireless nodes (41 to 48), and redirect means for causing the wireless communication means (21) to send the data to one of the wireless nodes (41 to 48) and to transfer the data to the other gateway device (3 or 2) connected to the wired network.
