Product Overview 2.1.Project background Under the Illumicare Group Limited's entrustment, Wanliankeju has developed a regional control system (also known as astronomical clock system) based on the 2.4 GHz frequency without protocol stack, that is, the first generation of Merlin..(2) The The system adopts three components: MASTER SLAVE and RX. Timing functions (including sunrise and sunset) are controlled by MASTER. Since sunrise and sunset need to be calculated according to the location of the user, the MASTER built-in GPS module makes the product cost higher. With the progress of technology, smartphones gradually enter the hands of ordinary users, the Internet of things platform has become mature. Since smartphones have built-in GPS modules and the integration of smartphones and Internet of things platforms can provide a more diverse operation and a good user experience, MASTER is no longer necessary. Therefore, the development of a new generation of Merlin products has a certain feasibility. At the same time, because the product access to the Internet of things platform needs to pass through the Internet, and outdoor products are not suitable for laying network lines, the communication mode based on Wi-Fi is more suitable. 2 / 13 Copyright 2019 KOJ Electronic Co., Ltd. All Rights Reserved. On the other hand, because the communication distance of the Wi-Fi is limited (the effective distance is only ten meters to tens of meters), Illumicare Group Limited hope that the HUB can make up for a certain lack, so it is required that the communication distance can be reached farther. Through investigation, the R & D team decided to use LoRa technology to replace the original no-negotiation stack 2.4 GHz, so that the communication distance can reach thousands of meters. The new generation of Merlin products is a set of regional control system using Wi-Fi and LoRa dual communication mode.
