Method and system thereof for monitoring and controlling environments of public place based on Zigbee

Abstract

The invention discloses a method for monitoring and controlling environments of a public place based on Zigbee, which comprises the following steps of: collecting environmental parameters in a public place by using a wireless sensor network, sending the acquired environmental parameters to a controller, and carrying out fuzzy modeling and chaotic modeling on the acquired environmental parameters by the controller; establishing a fuzzy neural network according to an established environmental parameter model, and carrying out real-time control on a working apparatus by utilizing the fuzzy neural network; and carrying long-term control on the working apparatus in the public place by utilizing a chaotic perturbation control method. In the invention, the fuzzy neural network and the chaotic perturbation control method are combined together, and the working apparatus is controlled according to season change of natural conditions, such as sunshine, temperature, and the like at the site of the public place so as to achieve the purposes of energy saving and humanization. Furthermore, the wireless sensor network adopts a wireless sensor network based on Zigbee, has the characteristics of anad hoc network and low power consumption and avoids the arrangement difficulty of a collection point when the traditional cable is wired.

Description

technical field [0001] The invention belongs to a public place environment detection and monitoring method, in particular to a Zigbee-based wireless intelligent environment monitoring and control method in a public place controlled by a non-linear method, and to a device used for implementing the method. Background technique [0002] The current environmental monitoring system in public places is difficult to meet people's needs for comfort and control convenience, and there are mainly the following shortcomings: [0003] 1. Backward management: The lighting and temperature of traditional public places are managed and operated by people, which cannot adapt to the dynamic changes in the number of people and vehicles in public places, and it is not easy to adjust in real time according to changes in weather and weather. [0004] 2. Energy waste: In public places, there are often many lights on when there is no one there, or the air conditioner is running. [0005] 3. Inconven...

Problems solved by technology

[0002] The current environmental monitoring system in public places is difficult to meet people's needs for comfort and control convenience, and there are mainly the following shortcomings:

[0003] 1. Backward management: The lighting and temperature of traditional public places are managed and operated by people, which cannot adapt to the dynamic changes in the number of people and vehicles in public places, and it is not easy to adjust in real time according to changes in weather and weather.

[0004] 2. Energy waste: In public places, there are often many lights on when there is no one there, or the air conditioner is running

[0005] 3. Inconvenient control: For example, lighting control requires all-night lights, midnight lights, period lights, early morning lights, night scene lights, etc., and the traditional environmental monitoring system cannot realize different control methods for different environments

[0006] 4. Complicated wiring: The wiring of the traditional environmental monitoring system itself is already very complicated. If more control functions are to be realized, the wiring cost is unimaginable

However, Bluetooth technology has a short transmission distance and high power consumption, and the network capacity is small, so it is not applicable.

The disadvantage of wireless LAN is high cost and high power consumption

[0007] 5. Short service life of equipment: The traditional control method adopts the method of direct opening and direct closing, which greatly shortens the service life of the control equipment under the impact of grid voltage and surge voltage

[0008] 6. Low security: the traditional environmental monitoring system has no security mechanism and cannot guarantee the security of the system

[0009] The application number is 200710156210.X, and the invention title is "greenhouse environment monitoring system based on ZigBee wireless sensor network". Cost, self-organization, and self-recovery wireless greenhouse environment monitoring network, but the patent application for this invention does not provide an effective control method to adapt to the changing and complex environment in public places, and achieve the purpose of humanized and economical control
