Description

A wireless LED lighting control system

technical field

The present invention relates to the field of LED lighting control technology and wireless personal area network, in particular to an LED based on the combination of IEEE 802.15.4 standard LR-WPAN (Low-Rate Wireless Personal Area Network) technology and WEB technology. Lighting wireless control system.

Background technique

As a new type of lighting technology, LED has attracted worldwide attention for its application prospects. LED lighting has become a trend in the field of lighting to replace traditional lighting. High-brightness LED lamps are known as the most valuable light source in the 21st century, which will surely cause a new revolution in the field of lighting.

Therefore, at present, traditional lighting fixtures are facing severe challenges from LED lamps. The main reason for this situation is that LED lamps have the following three main advantages:

1. Energy saving. Since LED is a cold light source, semiconductor lighting itself has no pollution to the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes. If LEDs are used to replace 50% of our current traditional lighting, the electricity saved in my country every year is equivalent to the sum of the power generation of a Three Gorges Power Station, and its energy-saving benefits are very considerable.

2. Health. LED is a green light source. LED lights are driven by DC, no stroboscopic, no infrared and ultraviolet components, no radiation pollution, high color rendering and strong luminous directionality, good dimming performance, and no visual errors when the color temperature changes. Cold light sources generate low heat and are safe to touch; these are incomparable to incandescent and fluorescent lamps. It can not only provide a comfortable lighting space, but also meet the physiological health needs of people. It is a healthy light source that protects eyesight and is environmentally friendly.

3. Artistry. LED has shown unparalleled advantages in color art. At present, color LED products have covered the entire visible spectrum range, and have good monochromaticity and high color purity. The combination of red, green and yellow LEDs makes the color and grayscale (16.7 million colors) ) has greater flexibility in selection.

At present, LED lighting is mainly used in room lighting, building lighting, and landscape lighting. Through the control of lights, the lights can be chased, flowing, jumping, etc., so that the lights can establish composition, order and rhythm, and can give full play to the lights. artistic expression. However, in order to achieve the coordination of various artistic elements such as lighting changes, colors, brightness, and music rhythms, a complex automatic control system must be adopted.

At present, the LED lighting control system mainly uses the following technical methods to achieve dynamic LED lighting control effects:

1) Adopt DMX512 communication protocol mode: This mode adopts distributed and modular computer network technology control system, the communication interface adopts the general EIA-485 standard in computer communication, and uses optical fiber or network cable to transmit control signals.

2) Network control system using EIA-485 standard interface: the system uses optical fiber or network cable to transmit control signals. The system communication protocol generally adopts the EIA-485 standard or the format defined by the manufacturer. A maximum of 128 multiple main control units can be connected, and a maximum of 128 terminal loop controllers can be controlled. Terminal to lamp adopts serial or parallel TTL signal control mode.

3), using large-screen display control mode: this mode is mainly composed of CPU microprocessor, standard communication interface with host computer, standard communication interface with display driver module and ambient light intensity detection module to form a standard control module hardware structure, By compiling different software, it can be used in different places. The standard communication interface with the upper computer and the standard communication interface with the display driver module can adopt standard RS232, RS422AK or RS485 communication interface.

From the description of the above three methods, it can be seen that the existing LED lighting control methods have the following two disadvantages:

The first is to solidify the lighting effect scheme in the controller and select it through the buttons on the controller panel. Users can only choose from the schemes in the controller and cannot add new lighting effect schemes, so the application is not flexible;

Second, the signal transmission depends on the twisted pair of 485 interface, which greatly reduces the flexibility of use, and when the number of lamps increases, a large number of cables will take up space and increase the cost of the system, making the system very bloated and difficult to install. extension.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the wireless personal area network to which the present invention is applied is firstly described in detail below.

IEEE 802.15.4 is a low-speed wireless personal area network (Personal Area Network) standard determined by the Institute of Electrical and Electronics Engineers (IEEE). The standard focuses on low energy consumption, low-speed transmission, and low cost, and aims to provide a unified standard for low-speed interconnection between different devices within the personal or family range. The standard defines the Physical Layer (Physical Layer, PHY) and the Medium Access Layer (Medium Access Layer, MAC).

The physical layer (PHY) specification defines a low-power spread-spectrum radio on the internationally accepted ISM 2.4GHz, and also specifies two operating frequencies of 868MHz and 915MHz.

The Medium Access Layer (MAC) specification defines how multiple IEEE 802.15.4 radios operating in the same area share the air channel. The media access layer has the following characteristics:

Three different transmission rates of 20kbps, 40kbps and 250kbps are realized under different carrier frequencies;

Support star network and mesh network two network topologies;

There are two address formats, 16-bit and 64-bit, of which the 64-bit address is the only extended address in the world;

Carrier Sense Multiple Access with Collision Avoidance (CSMA-CA) that supports collision avoidance;

Support acknowledgment (ACK) mechanism to ensure transmission reliability.

In the IEEE 802.15.4 network, according to the communication capabilities of the device, it can be divided into a full-function device (Full-Function Device, FFD) and a reduced-function device (Reduce-Function Device, RFD). Both FFD devices and between FFD devices and RFD devices can communicate. RFD devices cannot communicate directly with each other, but can only communicate with FFD devices, or forward data through an FFD device. The FFD device associated with the RFD is called the RFD's coordinator (Coordinator). RFD equipment is mainly used for simple control applications, such as light switches, etc., the amount of transmitted data is small, and the transmission resources and communication resources are not occupied, so RFD equipment can adopt a very cheap implementation scheme. The network coordinator is the main controller in LR-WPAN. In addition to directly participating in the application, it also needs to complete tasks such as membership management, link state information management, and packet forwarding.

According to the needs of the application, the IEEE 802.15.4 network can be organized into a star network or a mesh network.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a topology structure of a star network. In the star network, the network coordinator 11 is the center, and all devices communicate with the network coordinator. How a network determines its own network coordinator is determined by the upper layer protocol. When FFD is activated for the first time, it first broadcasts a request to query the network coordinator. If a response is received, it means that the network coordinator already exists in the network, and then through a series of After the authentication process, the device becomes a common device in the network. If no response is received or the authentication is unsuccessful, the FFD device can establish its own network and become the network coordinator of the network. The network coordinator selects a unique identifier for the network, and all devices in the star network use this identifier to specify their own ownership. After selecting the identifier, the network coordinator allows other devices to join its network and forwards data packets for these devices.

As shown in FIG. 2 , FIG. 2 is a schematic diagram of a topology structure of a mesh network. In a mesh network, as long as any two devices can receive each other's wireless signals, they can communicate directly without forwarding by other devices. However, a network coordinator 21 is still required in the mesh network, but the function of the coordinator is no longer to forward attributes for other devices, but to complete basic network management functions such as device registration and access control. The generation of the network coordinator is also stipulated by the upper layer protocol, for example, the first device to start communication on a certain channel is used as the network coordinator on the channel.

Therefore, based on the low speed and low power consumption characteristics of the IEE 802.15.4 standard, wireless personal area networks can be applied to many fields such as industrial monitoring and environmental monitoring. Since LED lighting control requires a short-distance and low-speed transmission method, the wireless personal area network based on the IEEE 802.15.4 standard is very suitable for application to LED lighting control. Although there are currently products that use wireless to control LED lighting, but The concept of wireless personal area network has not been introduced into the field of LED lighting control, and the IEEE 802.15.4 standard provides an interface for the network layer, which can facilitate the development of routing protocols, making wireless personal area network have great scalability.

The present invention is based on the low-speed wireless personal area network of the above-mentioned IEEE 802.15.4 standard, and provides a wireless LED lighting control system.

As shown in Figure 3, Figure 3 is a structural block diagram of the LED lighting wireless control system provided by the present invention, the system includes a lighting scene file website unit 31, a local computer unit 32, a wireless personal area network unit 33 and an LED unit 34.

The wireless personal area network unit 33 is used to receive the lighting scene data from the local computer unit, store them, and control the LED unit. The wireless personal area network unit 33 includes a network coordinator node, a router node, and a terminal device node.

Among them, the network coordinator node is used to assign addresses to nodes in the network, receive and store lighting scene data from the local computer unit, send the received lighting scene data to the router node, and control the entire LED lighting wireless control system. The network coordinator node contains a routing table, which stores the path to each node in the network, and the network coordinator node sends the lighting scene data to the relay router node and the terminal device node according to the stored path. The network coordinator node is connected to the local computer unit through a serial port, and the network coordinator node provides a keyboard interface and an LCD display to number the lighting scene data, and controls the LED module to display predetermined lighting effects through keyboard input.

The router node is used to realize the discovery and selection of the network path, send the lighting scene data received from the network coordinator node to the terminal device node of the LED unit, and control the switch and brightness of the LED lamp. Router nodes include relay router nodes, control router nodes, and terminal device nodes. Among them, the relay router node is used to forward the lighting scene data received from the network coordinator node to the control router node; the control router node is used to use the terminal device node as its child node to form a star network to realize the control of LED lamps . The relay router node and the control router node each contain a routing table which stores routes to the network coordinator node and other router nodes. The relay router node and the control router node are fixed on the wall or building, powered by a DC stabilized voltage, and control the switch and brightness of the LED lamps wirelessly.

The terminal device node is used to provide the interface between the control router node and the LED lamp, and transmit the control signal received from the control router node to the LED lamp in real time, so as to control the light and brightness of the LED lamp to change according to the expected scheme.

The wireless personal area network unit 33 may further include a remote controller. The remote control includes a router node and a keyboard, which are used to centrally or hierarchically control the switch and brightness of multiple groups of lights. The lighting scene program is stored in the router node of the remote control, and the address of the LED lamp to be controlled, the address of the router node or Lighting scene number, the control signal is transmitted to the destination node in a multi-hop manner, and the switch and brightness of the LED lamp are controlled. The control signal sent by the remote controller is received by the router node, and the switch and brightness of which or which LED lamps are specifically controlled are determined by the load of the control signal data frame.

The wireless personal area network unit 33 is a tree topology network constructed on the basis of a star topology network structure, and the tree topology network is a multi-hop network.

The LED unit 34 is used to receive a control signal from the wireless personal area network unit to realize a specific lighting effect. The LED unit 34 includes an LED light fixture and an LED drive circuit. The LED drive circuit is used to analyze the data sent by the router node, and to drive the LEDs of three colors R/G/B to emit light in the mode of PWM to control the length of the LED light emitting time. The color change of the lamp light.

The present invention combines WEB technology and wireless personal area network technology and applies it to LED lighting control, and downloads the lighting field installation scheme from the Internet to the LED lighting system in the form of wireless personal area network.

In order to overcome the disadvantages of inflexibility and poor scalability of the existing LED lighting control system, the lighting scene scheme is provided to users through the Internet for users to choose, and the user can edit the required scheme through the lighting scene software, or edit the scheme Upload to the website.

In order to solve the shortcomings of the existing LED control system, which uses a wired method, which takes up a lot of space, is expensive, and is inconvenient to maintain, a wireless personal area network is used to replace the wired connection method. The IEEE802.15.4 standard focuses on low speed and low power consumption, and the radio frequency transmission power is low. It only defines the physical layer and the MAC layer, and does not involve high-level protocols. It can only form a star network and a simple mesh network. The problem is that the transmission distance is limited, and the transmission distance is within the range of ten meters to tens of meters under the condition of 2.4GHz. When the working range needs to be expanded, it cannot meet the requirements, and the system expansion is difficult.

The present invention provides a multi-hop routing method to solve the above problems, adding router nodes in the network, so that information can be forwarded to the destination device through the router, expanding the working range of the network, ensuring error-free transmission of data, and at the same time enhancing the system scalability. The specific plan includes the following:

In terms of WEB, an LED lighting scene website is established, which is maintained by technicians and provides downloads of various lighting scene solutions. In order to enable users to continuously obtain the latest lighting scene solutions, technicians keep updating the content of the website and put the prepared lighting scene files on the website. Users can log in to the website to download the scheme through the lighting scene software, or edit the scene scheme through the lighting scene software, and if users are interested in sharing their own schemes, they can upload them to the website through the lighting scene software for other users to experience.

The description of the lighting scene software is as follows:

1) The software can be used as a browser to log in to the LED lighting scene website, and download files from the website, and can also upload local files to the website through the lighting scene software;

2) Edit the lighting scene scheme, provide a graphical interface to select the number, color, and dynamic effect of LED lights, and generate a lighting scene file, which is in the same format as the lighting scene file downloaded from the server;

3) The software can interpret the downloaded lighting scene files, provide a virtual environment to preview the lighting effects, and truly reflect the lighting effects;

4) The lighting scene file is only used for previewing on the computer and cannot be recognized by the LED driver module. After previewing on the computer, the lighting scene software can convert the lighting scene file into data that the LED module can recognize;

5) The software includes a serial port communication module, which downloads the converted data to the coordinator of the wireless personal area network through the serial port of the computer.

The software can also observe the status of the network in real time, discover network errors, and identify newly added nodes.

In terms of wireless personal area network, the IEEE 802.15.4 standard only defines the physical layer and the MAC layer, but does not involve the network layer, and can only form a single-hop network, and because the transmission power of the device is low and the transmission distance is limited, making a single Hop networks have less coverage. In order to solve this problem, the present invention establishes a multi-hop network based on IEEE 802.15.4, and adds router nodes on the basis of the star network to form a tree topology.

According to the tree topology of the network, when designing the routing protocol of the network, considering that most of the nodes in the network seldom move, a table-driven routing protocol is adopted. Each coordinator node and router node in the network maintains a table that contains routing information to all other nodes in the network, called the routing table. The structure of the routing table entry is composed of the destination node address, the next hop node address, and the number of hops. When a change in the network topology is detected, the node sends an update message in the network, and the node receiving the update message updates its own table to maintain timely and accurate routing information. The establishment and maintenance of the routing table is implemented through periodic broadcast routing update packets. Nodes will automatically select the minimum number of hops to store as a path. Since nodes rarely move, the routing table does not need to be updated frequently. Each component in the network is described below.

The grid coordinator is responsible for organizing and establishing a tree network, assigning addresses to nodes in the network, controlling the entire LED lighting system, and connecting to a computer through a serial port. The child nodes of the coordinator are router nodes. The coordinator numbers and stores the lighting scene data obtained from the computer. The coordinator stores a routing table, which contains the path to each node in the network, and the router sends the scene data to its child node - the terminal device node after receiving it. The coordinator provides a keyboard interface and an LCD display, and also numbers the lighting scene data, and controls the LED module to display predetermined lighting effects through keyboard input.

Router nodes realize the discovery and selection of network paths. Some router nodes use terminal devices as their child nodes to form a star network, called control router nodes; other router nodes only need to forward data, called relay router nodes. Routing tables are also stored in router nodes, containing paths to coordinator nodes and other router nodes. In the system, router nodes are generally fixed on walls or buildings, powered by DC stabilized voltage. According to the needs of the site, some router nodes are made into wireless switches to replace the original mechanical switches, which can control LED lamps in a centralized or grouped manner. switch and brightness.

As a sub-node of the router, the terminal device node is responsible for providing the interface with the LED module, and transmitting the received control signal to the LED module in real time, so as to control the light to change according to the expected scheme. The LED module is designed with an LED drive circuit, which is responsible for analyzing the data sent by the terminal equipment, and drives the three-color R/G/B LED light-emitting time by means of MCU control PWM, and controls the color of the LED light change.

There is also a remote controller in the network, which is composed of a router node, LCD and keyboard, which can centrally or hierarchically control the switch and brightness of multiple groups of lights. Several groups of lighting scene programs are stored in the remote control, and the address of the LED or router node to be controlled, as well as the number of the lighting scene are input through the keyboard, and transmitted to the destination node through multi-hop. The data sent by the remote control is only received by the router node, and which lamp or lamps to control is determined by the load of the data frame.
