Abstract:
To address the limitations of remote monitoring for multi-motor operational status in industrial production, a long-range radio (LoRa) wireless network-based intelligent remote monitoring system was designed for multi-motor systems. The motor’s status information such as vibration speed, acceleration, displacement, temperature and other status information was acquired through sensors. This data was subsequently transmitted to a remote computer using a LoRa wireless network, achieving remote monitoring of the motor’s operational status. An alert signal was triggered in case of any anomalies in the motor’s operation, indicating the need for taking effective intervention measures. The information transmission network adopted a master-slave architecture, where one receiving terminal communicated with multiple acquisition terminals to monitor the operational status of multiple motors within an industrial plant. The motor status monitoring system was designed with an independent power supply for ease of installation and maintenance. Ultimately, an experimental platform was established to perform functional tests on the designed monitoring system. The results show that the designed monitoring system is capable of acquiring the motor’s status information in real-time and with stability, thus verifying the system’s stability and reliability. The application of this system is beneficial for ensuring the safe operation of motors and maintaining the regular progression of production.
