Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the examples.

[0031] The field instrument monitors the status of the controlled object in real time, collects different data information, performs data processing and preliminary fault diagnosis locally, and then transmits the compressed data to the factory-level monitoring center through the wireless network for fault diagnosis. The local monitoring center cannot identify Faults can be submitted to the remote fault monitoring center for consultation by experts. The fault results are displayed in various ways such as local instruments and monitoring centers, and support the transmission of results by 3G network smartphones.

[0032] An equipment failure pre-maintenance system based on industrial wireless technology, including the composition structure of the system, the working mode of wireless instruments, the composition mode of wireless network, the factory-level fault monitoring ce...

Abstract

The invention relates to a device fault pre-maintenance method based on an industrial wireless technology. In the method, through data communication of an industrial wireless network and an industrial Ethernet, real-time monitoring and fault pre-maintenance are performed on an on-site device. The method includes the following steps: an upper computer performs parameter configuration on on-site instruments, which are used for monitoring the device, through the industrial Ethernet and the industrial wireless network; the instruments acquire sensor information of the on-site device according to the parameter configuration and upload result data, which is obtained after local processing of the sensor information, to the upper computer through the industrial wireless network and the industrial Ethernet; the upper computer performs fault diagnosis according to the result data and judges the operation state of the device; and if the fault diagnosis result is obtained, on-site maintenance personnel are notified through a fault alarm so as to maintain the device.

Description

technical field [0001] The present invention relates to a method of equipment fault pre-maintenance based on industrial wireless technology, specifically a wireless fault pre-diagnosis for rotating machinery (motors, fans, pumps, etc.) based on vibration, voltage, current, temperature and other signals method. Background technique [0002] With the advancement of technology, the modern process industry is developing in the direction of large-scale, integrated, automated and high-speed. The production process has higher and higher requirements for the reliability of equipment operation, which requires continuous, efficient and long-term operation under harsh working conditions. Unexpected failure of key equipment in the process industry will cause serious economic losses, even catastrophic consequences of casualties and severe environmental pollution. Therefore, building an efficient and reliable mechanical equipment maintenance system is an effective means to reduce costs,...
