Intelligent window control system used for energy conservation and fire fighting

Abstract

The invention belongs to the field of electronic security protection and discloses an intelligent window control system used for energy conservation and fire fighting. The objectives of energy conservation and fire fighting are achieved by utilizing Zigbee wireless technology and CAN (controller area network) bus technology to realize flexible combining of control nodes, utilizing a standby battery to realize normal working of the system during a power failure, realizing artificial control through a manual control box, an infrared remote control unit, a cellphone and a personal computer and detecting environment parameters through various sensors to realize automatic control of a window so as to improve daylighting, ventilation, heat radiation and smoke and dust discharging of a building. The intelligent window control system is composed of the window control nodes, a window controller, the infrared remote control unit, the personal computer, a main controller and the cellphone. The intelligent window control system has the advantages of low cost, low power consumption, safety, reliability and the like, and has huge energy saving potential. The window can be timely opened for smoke and dust discharging when a circumstance that smoke exceeds the standard is detected, so that the circumstance can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of electronic security. Background technique [0002] It is extremely important to make full use of sunlight to supplement indoor lighting in large public buildings with concentrated population, and to set up necessary ventilation facilities. On the one hand, sunlight is a safe, efficient, green and clean sustainable energy, which can effectively reduce lighting energy consumption. On the other hand, it is beneficial to people's health, reduces the concentration of harmful gases such as carbon dioxide in buildings, and also helps to take away indoor excess heat with dirty air in summer. [0003] According to the statistics of the causes of casualties in fires in the United Kingdom, those who died of suffocation due to carbon monoxide poisoning or were suffocated by other toxic fumes generally accounted for 40% to 50% of the total number of fire deaths, and among the people who were burned to death, most of them died f...

AI Technical Summary

Problems solved by technology

[0004] The traditional window control system mainly relies on the field bus. For buildings that have been put into use, it is troublesome to install and wire. Recently, some people have proposed to use Zigbee wireless network to realize intelligent window control. A window is controlled by a Zigbee node. For In places with many and dense windows, there are many control nodes, which will inevitably lead to excessive network load, high cost and waste of resources; at the same time, the existing window control system has not fully considered intelligent coping strategies in various environments, and failed to realize Humanized control method with multiple control methods, single function, poor scalability, cannot meet the requirements of large public buildings for energy saving and fire protection of windows
