Double-frequency-band communication device for indoor light sensor wireless network

Abstract

The invention provides a double-frequency-band communication device for an indoor light sensor wireless network. The double-frequency-band communication device is a wireless network communication device of a tree cluster shape which is connected with gateway nodes and sub nodes in a cluster in an indoor light environment wireless network and can receive wireless data in two different frequency bands, so danger of breakdown of the whole system due to the same frequency interference and loss of important data during switching of the frequency bands can be avoided effectively, and the data processing capacity of the light sensor wireless network is improved. The double-frequency-band communication device comprises a wireless network data processing device and a wireless network data acquisition device, wherein the wireless network data processing device comprises a first main control module, a first wireless network communication module, a first frequency setting module, a universal serial bus (USB) interface module, a communication quality indication module and a double-core communication quality monitoring module; and the wireless network data acquisition device comprises a second main control module, a second wireless network communication module, a second frequency setting module, a data acquisition indication module and a power supply management module.

Description

technical field [0001] The invention relates to an indoor light environment wireless sensor network monitoring system, in particular to a dual-band communication device based on the indoor light sensor wireless network. Background technique [0002] The light environment is the environment formed by light irradiating on its internal and external spaces, including outdoor light environment and indoor light environment. Light environment design is an integral part of modern architectural design. Its purpose is to pursue reasonable design standards and lighting equipment, save energy, and meet people's work, life, aesthetics, and vision protection requirements. Commonly used light environment parameters include illuminance, brightness, chromaticity, ultraviolet irradiance, annual exposure, etc. Accurate test data can provide real light environment information, provide a basis for the evaluation, planning and design of indoor lighting systems, and at the same time prevent harm ...

AI Technical Summary

Problems solved by technology

[0003] (1) Each sensor is measured independently, lacking a common networking protocol and system network;
