| The demand of today’s consumer electronics products become more and more vigorous, the factory manufacturing corresponding capacity also increases. Some large high-speed automated production equipment is more and more popular, with each enterprise of large equipment continues to increase, also put forward higher requirements for the operators and repair personnel. In order to guarantee the normal operation, operators need to adjust the equipment state maintenance, at the same time, managers also need real-time understanding of all equipment operation status and production capacity and other information. According to the equipment state information timely adjustment of production capacity, the equipment on the best and the optimal state. So the industrial equipment operation state monitoring is particularly important.At present, the domestic electronic manufacturing enterprises on the high-speed chip shooter machine, high-speed punching machine, running state monitoring forming machine and other large equipment are generally using the artificial observation and sound alarm. Artificial observation has obvious deficiencies, artificial observations are long cycle, low efficiency, heavy workload, the statistics easily; at the same time, manual monitoring to real-time control the running state and the production index of industrial equipment, all these will affect the production efficiency and cost as well as an industrial site management, centralized monitoring technology and products on the production equipment of domestic electronic manufacturing enterprises.This article through to keep track of domestic electronic manufacturing enterprises industrial equipment monitoring system development present situation, design of state monitoring system for industrial equipment based on wireless transmission network based on embedded system and wireless communication network. The whole system consists of host computer PC, integrated data processing terminal, wireless data acquisition terminal etc.. Integrated data processing terminal based on Cortex-M3processor STM32F103RCT6as the core is responsible for integrating wireless data acquisition terminal to upload data and upload to the host computer, at the same time through the TTS speech synthesis technology issued equipment abnormal state information; wireless data acquisition terminal is responsible for each other through state switch input as well as RS-232C and other interfaces collection of industrial equipment transmits data to integrated data processing terminal via the wireless communication unit, while the2GB Micro SD to store the historical data, with128X64LCD screen to display equipment status, and convenient debugging and maintenance. The PC software for analysis and statistics by the state of equipment data, real-time remote display equipment status, and also through the storage management of relevant data query database technology.This system has passed the enterprise acceptance and put into operation, the operation condition is real-time monitoring of19high-speed SMT line. |
