1. Application scenarios
Users need to collect basic energy consumption data and upload it to the management system in order to use a PC for real-time and remote data monitoring.
2. Technology selection
The 2.1 three-phase monitoring circuit has a rated voltage of 415Vac L-L and a rated current of less than 80A AC, so the choice of metering device will be the ADL400 three-phase energy meter, RS485 communication with MODBUS-RTU protocol
2.2 After discussion with the customer, the factory has stable 4GHz WiFi coverage and signal, it is best to use a 220Vac power supply. Therefore, for the gateway part, we choose the AWT100 WiFi, which has an auto-broadcast function that facilitates the subsequent adjustment of the ADL400. In addition, the AWT100 WiFi is paired with the AWT100-POW power module. In addition to this, since the AWT100 WiFi uses MODBUS-RTU upstream of 2.4GHz WiFi via tcp protocol, the MODBUS-RTU protocol downstream of RS485 and is paired with ADL400 in order to upload energy consumption data to cloud servers and finally to IoT systems.
2.3 During the pilot phase, it is highly recommended that the cloud server use the cloud server rented by our company on Amazon to save the customer's budget during the testing phase.
2.4 According to the requirements, the IoT energy management system will be the most suitable system and can provide a free trial for 3 months.
3. Pilot project solution structure
4. Post-pilot program
If the pilot project proves successful, future plans should be as follows:
4.1 Cloud Hosting Service Solution: Considering the comprehensive cost of renting a cloud server and the number of monitoring circuits, the deployment of the cloud IoT energy management system should be matched with the hosting service. In this case, the customer does not need to pay the rent of the cloud server, but uses our own cloud server. In addition, the hardware for the solution does not require any changes like the pilot project solution structure. Customers simply order additional ADL400 three-phase energy meters and order AWT100 WiFi gateways based on the number of subsequent requests.
4.2 Local Acquisition Service Solutions: If the customer has higher requirements for data security and confidentiality. The buyout service of the IoT energy management system paired with a local server will be the best choice. However, the solution requires a lot of changes in hardware, for example. First, the deployment of local servers needs to be paired with industrial switches and UPS. Second, for energy meters, the ADL400 is more recommended. Thanks to the special module, the ADF400L multi-loop energy meter with built-in Ethernet communication does not save much budget in applications where three-phase wiring is done via direct connection instead of CTs. Finally, the gateway needs to change from AWT100-WiFi to AWT100-CE or Aport100 depending on the number of subsequent requests.
