SEA3700 series acquisition terminal: This includes SEA3700 concentrator and home display terminal IHD; complies with DLMS/COSEM specification; acquires process and store the data from smart meters, and also exchanges data with master station or handheld devices at the same time.
DDZY1339/DTZY1339 smart energy meter: This completes two-way energy metering and remote communication functions with the ability to act as the energy gateway for the communication between water, gas & heat meters and family display terminal IHD as well as to help improving the energy utilization efficiency and energy management.
Communication network: AMI master station system communicates in two ways with acquisition terminals or smart meters and realizes the communication architecture of AMI, including: upward communication mode, mainly referring to the access under multiple remote modes, such as GPRS/GSM, Ethernet, BPL and optical fiber, etc.; and downward communication mode, covering carrier(PRIME, G3 and IEC61334 international standards) and micro-power wireless (Zigbee, Wifi, Bluetooth and M-Bus) network modes, or RS485 and RS232 bus modes.
