A wireless control system for intelligent conference room based on z-wave technology

Abstract

The application provides an intelligent conference room wireless control system based on Z-Wave technology. The intelligent conference room wireless control system comprises a Z-Wave Internet of Things controller, a Z-Wave terminal device, a conference room intelligent control application module, and a Z-Wave scene module. The Z-Wave Internet of Things controller is used for converting an Internet protocol into a Z-Wave protocol. The Z-Wave terminal device is used for controlling devices and sensing environment. The conference room intelligent control application module is used for performing centralized management and control on different Z-Wave terminal devices. The Z-Wave scene module is used for controlling multiple devices in a linkage manner and configuring conference scenes and environmental effects.

Description

technical field [0001] The present invention relates to wireless network control technology, more specifically, to a wireless control system for an intelligent conference room based on Z-Wave technology. Background technique [0002] With the steady development of smart city construction and the rapid development of science and technology, the concept of "smart" has been deeply rooted in the hearts of the people. In recent years, with the great enhancement of our country's national strength and the rapid development of modern information processing technology, various enterprises and institutions have higher and higher requirements for modernization. In order to better improve office efficiency, the conference room management system has gradually evolved from a purely listening and hearing-based communication place to a comprehensive information resource exchange place with multiple functions. A well-arranged meeting room is helpful for customers or partners to have a good ...

Problems solved by technology

[0005] In recent years, wireless control solutions based on ZigBee technology or 433Mhz (315Mhz) technology have appeared, but neither Zigbee technology nor 433Mhz technology has a general standard protocol, so the control protocol and reporting protocol between the control gateway and the device cannot Unified, the above two control gateways and devices can only use the private protocol defined by the user, and the provider of terminal equipment that cooperates with the control gateway is relatively single, so that users can only purchase matching control gateways when building a conference room system The terminal equipment of the manufacturer

In the end, the customer's terminal product selection and replacement channels are heavily dependent on a certain manufacturer, and the price of the product has always remained at a relatively high level; and the terminal products are limited by a small number of manufacturers, resulting in a fragile industrial ecological chain. As a result, the customer's system cannot be maintained, and the customer's maintenance risk and cost are greatly increased

[0006] Generally speaking, there are three main problems in the existing technology: first, no matter what kind of wireless technology can provide a unified application layer protocol standard, resulting in the inability of interconnection between devices; second, although Zigbee technology relies on IEEE802 .15.4 protocol stack, but the 2.4G wireless frequency band has been increasingly interfered by wireless signals such as WIFI, causing transmission congestion; other 868Mhz and 915Mhz, but if different frequency bands are used, the interconnection of devices cannot be guaranteed; in addition, Zigbee considers many applications such as industrial control and building intelligence when formulating the protocol, which leads to complex protocol formulation and high hardware cost, while Z-Wave focuses on the field of home intelligent control, with clear domain, simple structure and low cost. ; Third, although the cost of RF (433MHz and 355MHz) products is low, there is no standard interconnection protocol standard, even network control protocol and routing protocol, and it is impossible to guarantee reliable signal transmission.
