Telecommunications Tower Base Station Energy Monitoring Solution

Profile

Base station energy consumption monitoring can monitor the status of the base station power distribution system and the power consumption of each device, helping users to fully understand the operating status of the base station and provide energy consumption data as the basis for electricity bill settlement.
The base station power distribution system consists of AC and DC power distribution. The AC side can use AC multi-circuit meters to monitor the power consumption data of the mains, diesel generators, air conditioners, switching power supplies and other circuits; the DC side can use DC multi-circuit meters with Hall sensors to achieve energy consumption statistics by device, circuit or user.

Application Scenario

This solution was designed for precise sub energy monitoring of telecommunications tower base station.Normally, the power system of base station could be devided into AC part and DC part [-48Vdc]. And usually request a multi-channel metering regarding the different energy usage like for different telecommunications service provider's base station communications equipment [DC side]. Or for either the mains supply, back-up generator, lighting, airconditioner of base station. [AC side] Thus, multi-channel DC or AC energy meter will be the key to solve such request.

This solution was majorly for local energy monitoring, different from Acrel IoT Cloud energy monitoring solution which is designed for base station online cloud energy monitoring. In other hands, this solution could be also adapted to 3rd party IoT energy monitoring system by the integration between Acrel energy meter to 3rd party IoT gateways via RS485 [MODBUS-RTU protocol]. Or by the integration between Acrel IoT gateway and 3rd party IoT system via 4G, WiFi , Ethernet [MQTT or MODBUS-TCP protocol].

Communication Structure&Logic

IoT Energy Monitoring is the trend of future. So, if the customer/your side already have your own IoT system platform but don't have IoT gateway which has been already integrated with your IoT system. And in this case you don't need Acrel IoT system, but you want to receive the data from Acrel Energy Meter to your system instead. Then, the integration between Acrel AWT100 Series IoT gateway [either 4G, WiFi or Ethernet version] and your IoT system based on either MQTT or MODBUS-TCP protocol will be the key for overall system integration.
(1)Both AMC16L-DETT Multi-channel DC Energy Meter and DTSD1352-4S Multi-channel AC Energy Meter and AWT100 IoT gateway support RS485 communications based on MODBUS-RTU protocol.And between these devices, the integration of RS485 [MODBUS-RTU] part has been already done in factory stage. [Since they are all Acrel produced products]
(2)Thus, to make the overall communications structure complete, we only need to do the integration between Acrel AWT100 IoT gateway with your IoT system via 4G, WiFi or Ethernet communications methods based on either MQTT or MODBUS-TCP protocol. To do this part, Acrel side will provide either MQTT or MODBUS-TCP protocol file to your side for system integration.
