Implementation of Pump Condition Monitoring Function Based on Handheld Devices

As a large-scale device, pump equipment is usually stored in the industrial site, with the characteristics of complex site environment and concentrated equipment location, and requires on-site inspection personnel to regularly inspect to eliminate faults. The traditional central control room uses the PC to monitor the industrial site, and there is a common problem of untimely fault feedback, so it is necessary to use handheld explosion-proof equipment to obtain the equipment status immediately. Narrowband Internet of Things (NB IoT) and Bluetooth (BT) protocols are both wireless communication protocol technologies. Due to the widespread use of Bluetooth technology in mobile devices such as smartphones, it is necessary to design command formats and implement programs based on Bluetooth technology. As a more cutting-edge technology than BT, NB technology can serve as a supplement to system data transmission due to its low power consumption and low-frequency characteristics. Therefore, the work of this article mainly revolves around these two technologies. This article first explores the similarities and differences between NB and BT protocols in pump status monitoring, and then expands on how to develop command formats for specific pump equipment status monitoring tasks. Finally, based on the format of parameter setting commands and data packet transmission commands, the writing process of mobile terminal programs was explained, and the final implementation results were provided.
