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

Embodiment 1

[0048] Such as figure 1 As shown, the Zigbee-based public place environmental monitoring and control method among the present invention refers to: utilize wireless sensor network to gather the environmental parameter in the public place, the environmental parameter of acquisition is sent into controller, and the environmental parameter of acquisition by controller Carry out fuzzy modeling and chaotic modeling; according to the established environmental parameter model, establish a fuzzy neural network, use the fuzzy neural network to control the working equipment in real time; and then use the chaotic perturbation control method to control the working equipment in public places for a long time.

[0049] Specifically, the above-mentioned wireless sensor network can be based on any one of GSM or CDMA or Bluetooth or WIFI, using the above-mentioned wireless sensor network to collect environmental parameters in public places, and then using fuzzy neural network and chaotic perturba...

Embodiment 2

[0097] The difference between this embodiment and Embodiment 1 is that in this embodiment, the public place is a large event place, so the controller is a remote background control system. In this way, the calculation module in Embodiment 1 also needs to be connected to the log module, and the log module is connected to the database interface.

[0098] In order to provide multifunctional services, in the controller, the analysis control module is also connected with the alarm module, the display module, the WEB interface, and the mode management module; the above-mentioned display module is also connected with the calculation module and the log module; the above-mentioned The alarm module is also connected with the SMS module.

[0099] In this way, the analysis module analyzes and classifies the information received from the COM interface, and sends the corresponding results to the designated module:

[0100] (1) Send the received feedback abnormal situation and error message...

Embodiment 3

[0115] The difference between this embodiment and Embodiments 1 and 2 is that in this embodiment, the controller includes a remote background control system and a hand-held remote controller at the same time, so as to realize more comprehensive control.

[0116] At this time, the hand-held remote control should integrate ATMEL's ZigBee module circuit, and the wireless communication works in the frequency band of 2.4GHz or 780MHz, which has strong anti-interference ability. The CPU of the handheld remote control uses ATMEL's high-performance AVR processor ATmega1281, which integrates 128KB flash, 8KB SRAM, 4KB EEPROM, etc., 128KB flash and 8KB SRAM are used to communicate with the terminal and send and receive commands for controlling the device 4KB EEPROM is used to store fixed code data such as device identification code and terminal code; the display part of the handheld remote control uses a 128*64 blue-ray dot matrix LCM with a Chinese character library, and the input butto...

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.
