Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) communication technology, specifically to a multi-functional remote meter reading gateway device based on 4G communication and infrared acquisition. Background Technology

[0002] In current equipment monitoring, various monitoring devices are used to collect equipment operating status data. For example, electricity meters are used to record various electrical parameters such as maximum current, maximum voltage, power factor, and power consumption. Traditionally, meter reading was entirely manual, with electricians sequentially reading the data from each meter and recording it on paper. This work is not only time-consuming and labor-intensive, but also results in limited data recording, untimely updates, and occasional meter reading errors, failing to meet the demands of fully utilizing electrical data in the modern era. Therefore, wired automatic meter reading and infrared meter reading are now commonly used. However, both methods have certain drawbacks in practice. Wired automatic meter reading requires a pre-installed communication port on the monitoring meter, connected to the meter reader via cable or fiber optic cable. Infrared meter reading requires the infrared meter reader to be brought close to and aligned with a monitoring meter equipped with an infrared communication port, using infrared communication to read the monitoring data output by the meter. Compared to traditional meter reading methods, this greatly improves data acquisition efficiency and reduces meter reading errors, but still requires manual operation, which has limitations and restricts further improvements in meter reading efficiency.

The network communication module and the infrared meter reading module are both data connected to the main control module. The main control module is data connected to the corresponding cloud management platform through the network communication module and transmits the status information of the corresponding devices collected by the infrared meter reading module to the cloud management platform. The power supply module supplies power to the main control module, the network communication module, and the infrared meter reading module.
