Understanding the Enterprise IoT Solution - Energy Efficiency Management

Understanding the Enterprise IoT Solution - Energy Efficiency Management

Figure 26-2 shows implementation of the energy efficiency management IoT solution.

  1. Configure energy efficiency management policies on the BEMS and deliver them to the EEM.

  2. The EEM converts the energy efficiency management configurations into energy efficiency management policies and distributes the policies to the IoT gateway.

  3. Sensors send sensed data to ZigBee cards using 2.4 GHz radio signals. The ZigBee cards then report the data to the IoT gateway. The IoT gateway matches received data based on energy efficiency management policies, and sends matched policies to the function execution modules of sensors for energy efficiency management and control.

    For example, if the IoT gateway receives data indicating high temperature from a temperature sensor, it matches the data based on energy efficiency management policies. A matched policy is found, indicating the air conditioner should be switched on and adjusted to 26°C. The IoT gateway sends the policy to the sensor, and then the sensor function module executes the received policy.

  4. The IoT gateway sends the data reported by sensors to the BEMS. The BEMS centrally monitors environment parameters.

Network Interworking Between APs and Host Computers

On the network for energy efficiency management shown in Figure 26-3, an AP needs to establish TCP channels with two host computers.

  • The first channel is established between an AP and the Niagara container loaded on the IoT gateway. You can configure information such as a whitelist, card authentication information, and encryption information.
  • The second channel is an extended channel established between the AP and the EBT. The EBT control platform can detect ZigBee cards and sensors managed by the ZigBee cards. You can view the online status and versions of the ZigBee cards, as well as sensor information, and upgrade the ZigBee cards using the EBT.
