Data parsing and extraction

Protocol Conversion Algorithm

Data caching and transmission

Infrared acquisition moduleThe obtained electricity meter data is usually binary data encapsulated in DL/T645 or DL/T698 Protocol. The device parses these data and extracts key information such as electricity, voltage, and current.

according to IEC104ProtocolThe requirement is to repackage and encode the extracted electricity meter data. Including the construction of the frame header, data field, checksum, and other parts of IEC104 Protocol, and mapping the meter data to the corresponding fields. During the conversion process, attention should be paid to details such as data type conversion and byte order adjustment to ensure that the converted data complies with the IEC104 Protocol specification.

Temporarily store the converted IEC104 data, and then use it at certain time intervals or trigger conditionsCommunication Management UnitThe communication interface transfers data to theRemote Monitoringsystem. Infrared meter reading adopts infrared communication, which uses infrared technology to achieve close range communication between two points. It consists of two parts: infrared transmission and reception. The infrared meter reading device is based on the modulation and demodulation of 38kHz signals to achieve infrared andRS-485Signal conversion. The front of the infrared probe (usually with a 3M adhesive surface) is attached to the infrared communication interface of the electric meter to collect data, without the need for wiring. When using, pay attention to aligning the infrared probe with the infrared window of the electric meter, preferably at a distance of 0-3 meters, and can be separated by transparent glass.
