Single-fire switch control system based on BLE5.0

Abstract

The invention discloses a single-fire switch control system based on BLE5.0. The system comprises single-fire switches, a gateway, a server side and a personal terminal; each single-fire switch comprises a first BLE module, a power supply module and a switch circuit. The gateway comprises a second BLE module. The second BLE module is in wireless connection with the first BLE module; the gateway istaken as the center; a plurality of single-fire switches are wirelessly connected to form a star-shaped structure network; each of the first BLE module and the second BLE module comprises an LE CodedPHY protocol; the server side is connected with the gateway; the server side processes and controls the connection state of each single-fire switch and the gateway; the personal terminal comprises amobile phone APP, the personal terminal is in wireless connection with the server side, a user controls the state of each single-fire switch through the mobile phone APP, the single-fire switch control system is wide in communication range depending on BLE5.0, and a large number of single-fire switches are controlled through extremely few gateways.

Description

technical field [0001] The invention relates to the field of wireless intelligent switches, in particular to a single fire switch control system based on BLE5.0. Background technique [0002] With the development of the Internet of Things, more and more devices are integrated into the smart device network. Today, not only large electronic devices such as air conditioners and dehumidifiers are connected to the Internet, but also small devices such as lights and door curtains. There are two main control methods for networking, which are single fire switch and zero fire switch, and the single fire switch uses a live wire to take power. In the case of supporting 3W LEDs, in the off state, the main control part Can only use a small current to work. If it exceeds a certain current value, the LED will flicker, affecting customer application experience. At the same time, in use, the single live wire switch should have a relatively long control distance, so that in customer applica...

AI Technical Summary

Problems solved by technology

If the single live wire switch is connected to the gateway through a relay, it will increase the purchase cost of the customer

At the current stage of technology, the single-fire switch mainly uses Zigbee or BLE 1MHz PHY for wireless communication. Although these technologies have low energy consumption, they have the characteristics of small network coverage and prone to wildfires.
