The real time data collection of loom’s production, as an important factor of textileenterprise management, can support the enterprise management and decision.In this paper, acquisition card and regional processor are studied and designed to monitorthe real-time data of looms. For solving the problem that it is inconvenient to manage enterpriseinformation for various type equipments in woven fabric production enterprise. The mainfunction of collection card is the real-time acquisition and transmission of textile production data,while the area processor focuses on storage and transmission of data. A whole data acquisitionsystem includes acquisition card, regional processor and a upper computer, using distributednetwork structure. Each loom installing a collection card is connected by the RS485bus with theregional processor. Meanwhile, the regional processor transports the production data to the uppercomputer by the RS485bus.The design of the topic and actual development work is introduced in this paper. The maincontent studies includes three parts as follows:(1) Analyzing the current domestic and foreign loom data acquisition of the presentsituation and development trend, the loom monitor system hardware and communicationplatform that loom data acquisition system are put forward, comparing the heterogeneous loomdata signal transmission characteristics and performance.(2) The loom signal acquisition system design scheme is discussed. The related hardwaremodule design is also analyzed and described. Finally, we introduced the hardware circuit designof monitoring and regional processing.(3) According to the system design scheme, the design of software programs are discussedand tested by experiment. Meanwhile, the results are analyzed and the programs are optimized.
