and also supports full on-off control of bound RX.

APP

Applications running in smartphones, specifically Tuya APP. RX devices that

have been added to Wi-Fi same network can be controlled by Tuya APP,. Bind

the third-party smart speakers, also empty through the voice pair

Wi-Fi

A wireless communication protocol and networking technology, which

connects terminal devices through wireless routers to realize interconnection

between devices. Smartphones usually support the protocol.

LoRa

A low-power wireless transmission protocol based on spread spectrum

technology operates in the physical layer, mainly using Sub-GHz frequency

bands, and the communication distance can reach thousands of meters.

Distribution

network

The process by which a terminal device joins a network. Only after joining the

network can the equipment be interconnected. Such as RX devices join HUB

and SLAVE LoRa networks; HUB and router Wi-Fi networks.

Binding

The process of establishing interaction between terminal devices. After

binding, the transmitter device can control the receiver device. Such as SLAVE

and RX binding, user accounts and RX binding.

HUB

Wi-Fi network and LoRa network adapter. Use 12 V1A DC low voltage power

supply. APP can further control the RX. connected to HUB by controlling the

HUB network

2. 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.
