System for monitoring looms in weaving mill

摘要

A loom monitoring system includes loom computers and a host computer connected to the loom computers through a network. Each loom computer acquires a temporary IP address from a DHCP server when a fixed IP address is not set for the loom computer and requests the host computer to transmit a fixed IP address using the temporary IP address. The host computer assigns a fixed IP address to the loom computer that transmitted the assignment request signal and correlates the fixed IP address with a loom layout map. The loom computers each transmit an acquisition completion signal to the host computer using the fixed IP address in a designated order based on the loom layout map. The host computer correlates the fixed IP address of each loom computer with the loom layout map in accordance with the designated order.

主权项

1. A loom monitoring system comprising:
loom computers respectively coupled to looms installed in a weaving mill; a host computer connected to the loom computers through a network, wherein the host computer is configured to communicate with the loom computers to manage the loom computers; and a dynamic host configuration protocol (DHCP) server arranged in the network; wherein the host computer is configured to
manage fixed IP addresses to be assigned to the loom computers, andstore a loom layout map indicating where the looms are located in the weaving mill; each of the loom computers is configured to
transmit, when a fixed IP address is not set for the loom computer, a temporary IP address acquisition request signal to the DHCP server to acquire a temporary IP address from the DHCP server, andtransmit a fixed IP address assignment request signal to the host computer using the acquired temporary IP address; the host computer is configured to
assign fixed IP addresses to the loom computers that transmitted the assignment request signal,shift to a correlating mode when the assignment of the fixed IP addresses to the loom computers that transmitted the assignment request signal is completed, wherein the host computer in the correlating mode correlates the fixed IP addresses assigned to the loom computers that transmitted the assignment request signal with the loom layout map, andrequest each of the loom computers that transmitted the assignment request signal to transmit an acquisition completion signal so that the acquisition signals are transmitted from the loom computers in a designated order based on the loom layout map; each loom computer is configured to
register the assigned fixed IP address in lieu of the temporary IP address, andtransmit the acquisition completion signal to the host computer using the fixed IP address when the acquisition completion switch of the loom computer is operated in the designated order based on the loom layout map; the host computer is configured to, when receiving the acquisition completion signals, store and correlate the fixed IP addresses of the loom computers with the loom layout map in accordance with the designated order.
