Description

Dimming controller based on zigbee technology

technical field

The utility model relates to the technical field of smart home control, in particular to a dimming controller based on zigbee technology.

Background technique

With the development of smart homes, it is not only necessary to realize the intelligence of turning on or cutting off the light power supply, but also to accurately adjust the brightness of the light according to the light of the surrounding environment to make life more comfortable. Wireless remote control technology is the main development direction of smart home at present.

At present, the wireless appliance control technology mainly includes infrared wireless remote control, and 433MHZ, 315MHZ wireless ASK modulation wireless remote control. Infrared remote control has the characteristics of low cost, but it can only operate short distances within the visible range and cannot pass through obstacles.

ASK modulation wireless remote control can increase the wireless control distance by adjusting the transmission power, and has the characteristics of being able to pass through common obstacles. However, when multiple remote controls are operated at the same time, or multiple devices in the same frequency band are used together, mutual interference will be caused. Moreover, the communication is unidirectional. After the remote controller transmits data, it is impossible to confirm whether the control device has received it. When there is an interference source or other reasons that prevent the remote controller from receiving the instructions, the remote controller will also fail. This technology is also not convenient for networking. When used in a large area in the same area, mutual interference will be serious, and the networking settings are also relatively complicated.

Utility model content

The purpose of the utility model is to provide a dimming controller based on zigbee technology, which has the characteristics of ultra-low power consumption, strong anti-interference ability, convenient networking, and high safety and reliability.

The technical solution adopted by the utility model to solve the technical problems is: the dimming controller based on zigbee technology, which is characterized in that it includes a control execution module, an operation display module, and a touch button that are electrically connected to the zigbee wireless module, The control execution module is also electrically connected to the power interface and the load terminal; the zigbee wireless module is also electrically connected to the power interface through the AC/DC power module.

The load terminal is electrically connected to at least one light bulb.

The zigbee wireless module is a CC2430 chip embedded in the zigbee protocol.

The operation display module includes a buzzer and an LED indicator light.

The AC/DC power supply module is a single-chip switching power supply module, which is a 3.3v DC power supply after rectification and voltage stabilization.

The beneficial effects of the utility model are: the zigbee communication protocol of the utility model uses direct sequence spread spectrum technology, and has the characteristics of ultra-low power consumption, strong anti-interference ability, convenient networking and high reliability. It overcomes the weaknesses of co-frequency interference, inability to form a large-area network, and relatively large power consumption and current in some existing controllers. The zigbee wireless module is suitable for low-speed and high-reliability communication. It is very suitable for home appliance control. It only needs to transmit a small amount of data during work, and it is in a low-power standby state most of the time.

At the same time, the utility model is convenient for networking. Through the zigbee network coordinator, users can conveniently add and delete dimming control devices at any time, and arbitrarily combine the corresponding relationships of various control devices to maximize the advantages of wireless control.

Detailed ways

As shown in Figure 1, this dimming controller based on zigbee technology includes a control execution module electrically connected to the zigbee wireless module, an operation display module, and a touch button, and the operation display module includes a buzzer and an LED indicator Light, the operation display module uses the buzzer to prompt the command to be received successfully, and indicates the light and dark adjustment direction of the dimming through the LED. The light touch button is a kind of micro-motion electronic switch. When in use, lightly press the switch button to turn on the switch. When the hand is released, the switch is turned off. Move to achieve on-off.

The control execution module is also electrically connected to the power interface and the load terminal, the load terminal is at least electrically connected to a light bulb, and the light bulb directly connected to the load terminal is controlled by controlling the level of the I/O port of the zigbee wireless module The opening and closing and brightness.

The zigbee wireless module is also electrically connected to the power supply interface through an AC/DC power module, and the AC/DC power module is a single-chip switching power supply module, which is a 3.3v DC power supply after rectification and voltage stabilization (the system only needs 3.3V this voltage) to supply power to the dimming controller.

The zigbee wireless module is a CC2430 chip embedded in the zigbee protocol, compatible with 51 cores. The CC2430 chip is a system single chip conforming to the zigbee technical standard, which integrates an enhanced 8051 microcontroller core and a radio frequency transceiver conforming to the IEEE802.15.4 standard, and has excellent wireless receiving sensitivity and strong anti-interference performance. 256-level dimming control of lighting can be realized.

The zigbee wireless module realizes wireless network connection with the home intelligent gateway and the zigbee remote controller through the antenna.

The home intelligent gateway is a remote monitoring wireless gateway based on zigbee technology.

When working, the user sends wireless remote control instructions locally through the zigbee remote control or remotely through the home smart gateway. The zigbee wireless module returns the data to the remote controller after receiving the command, and at the same time the zigbee wireless module drives the buzzer on the display module to beep once, indicating that the command has been received; and controls the actuator through the I/O port level of the zigbee wireless module Perform dimming control. In order to facilitate the user to understand the current state of dimming, the zigbee wireless module drives the LED light of the operation display module to indicate the direction of dimming. When the user uses the button to operate, press the button of the tact switch once, and the on-off state of the bulb will be changed; when the user keeps pressing the tact switch, the dimming action of the brightness of the bulb will be performed.

When the utility model is installed, it directly replaces the common 86-box wall socket, and the electrical equipment to be controlled can be controlled by inserting it into the socket.
