The GPRS electric energy remote terminal of Xinkai Pu is an electric energy collection terminal developed using wireless data transmission services provided by China Mobile and China Unicom, combined with the actual needs of power users. This product is a cost-effective specialized transformer collection terminal that can collect electrical information from specialized transformer users. It is particularly suitable for applications that only focus on data collection and are sensitive to cost, volume, and construction and commissioning difficulties. The terminal has the advantages of small size, high cost-effectiveness, easy construction, low operating cost, reliable performance, and high degree of automation, and is highly welcomed by power users.
Functional Features
1. Adopting ARM platform to ensure system running speed and expansion space for programs and data;
2. Use GPRS communication method for uplink communication;
3. The downlink interfaces are RS485 and RS232, and communicate with the terminal using standard UART mode;
4. Equipped with data protection retransmission function, when GPRS channel communication fails, the data that needs to be sent can be backed up to non-volatile memory to ensure that the data will not be lost;
5. Through electromagnetic compatibility testing in industrial environments, it is safe and reliable.
