【Abstract】 The remote monitoring and fault diagnosis technologies have played a significant role in ensuring the security, stability and long-term high-quality operation of manufacturing equipment. In this dissertation, a research has been focused on the key technologies of remote monitoring and diagnosis and systemic realizable programme of QT10-15 concrete block molding production line.Based on the analysis of the system composing and implement method of PLC based system, a detailed research has been made on the serial communication mechanism of Delta EH-PLC in this dissertation. Based on the communications control of VB6.0, the PLC signal acquisition function of concrete block molding production line host is achieved. To make the monitoring signals diversified, an embedded computer motherboards + DSP embedded intelligent monitoring and maintenance unit is designed. This unit is the right equipment of the scene and audio information, as production, acquitting some analog signals and transmitting in a long distance. Based on C/S structure, the network connection between the concrete block molding production line host and the monitoring center server has been set up. Using the Sock mechanism and custom signal transmission protocol, the Ethernet-based data transmission between the concrete block molding production line host and monitoring center server is achieved. Researching the GSM communication technology, the abnormal of concrete block molding production line will be sent to the remote monitoring server in the form of short message. This is a powerful added to the cable transmission. Finally, analyzing the fault features, the fault diagnosis database of concrete block molding production line is designed with the access and ADO technology. The summary and analysis of historical data can be achieved. The data can provide the views of maintenance and improvement.It is proved by field experiment and operation that the designed remote monitoring system of the concrete block molding production line reaches the expected function demand. The design which is dependable and practicable satisfies the requirements of monitoring of production line.更多还原
