Solutions & Applications
Intelligent Remote Distribution Box Monitoring Solution The distribution box is embedded with the DTU distribution device, distribution device power module, and distribution device power supply. By leveraging the intelligent remote monitoring function, you can remotely collect the electric meter readings and implement networked transmission. In addition, with the help of electricity monitoring platform of USR Cloud, you can manage and control the electricity safety and electric energy over the cloud.
Remote intelligent meter reading In nowadays, the large number of various meters are dispersed in different locations, some of which are remote and difficult to access, a remote meter reading system is urgently needed to relieve staff of utilities from heavy but inefficient tasks.Traditionally, the utilities companies used to hire thousands of meter readers to go around to read the meter, and always spend much money on traffic and labor.
Application to Electric Fire Monitor System The cellular modem can be used in electrical fire monitoring system. In this application, we will introduce how to use industrial modem USR-G781 and industrial modem USR-DR504 in the electrical fire monitoring system.
