The infrared meter reading device is based on 38kHz signal modulation and demodulation, realizing the mutual conversion of infrared signals and RS485, and supporting the protocol conversion of DLT645-2007/DLT645-1997 standard meter protocols. It is suitable for monitoring, energy management system monitoring, ensuring that the data is consistent with the meter reading, and it can be used with the rail data collector to upload the monitoring data to the Whe Photovoltaic platform, and display it in a clear and intuitive form in the form of charts.

Compared with GPRS meter reading - no communication fees, not limited by signal coverage.
Compared with PLC power line carrier, it is not affected by grid noise interference and can be read immediately.
Compared with pulse acquisition - there is no cumulative error, and the data is completely consistent with the dial.
Extremely high reliability - mature technology, capable of stable operation in various environments.
No operating costs - one-time purchase, long-term use, no subsequent communication expenses.
The fastest deployment speed - it can be opened and put into use without any engineering required.
The lowest operating threshold - no professional IT knowledge is required, ordinary meter readers can operate it.
High data authority - directly reading the core data of the meter, with strong legal effect.
