Light source-based Internet of Things

The construction of an Internet of Things, in particular, utilizes the existing light source wiring in the building, and combines the light source for lighting into a node, a router, a communication gateway through Bluetooth and WIFI, and cooperates with Bluetooth and WIFI. As a device for setting and remote control, and the function of the Internet itself, the mobile phone itself can easily construct the Internet of Things in the building.

Smart buildings usually represent the need to build an Internet of Things in buildings. The construction of the Internet of Things has its advantages and disadvantages, whether it is using ZIGBEE or Bluetooth or WIFI or 3G. The power consumption, cost and penetration rate. The convenience, flexibility, and meshing of construction, etc., need to be considered. In particular, the penetration rate is the most important consideration. The penetration rate means that the Internet of Things features that “everything has a communication node” is easy to meet. Nodes that are universally communicable have no Internet of Things. Bluetooth or WIFI is currently the most popular communication solution, but only in computers, some computer peripherals, laptops, mobile phones, tablets, etc., general electrical appliances are still not set, even if the settings can not let electrical appliances in the building The material is generally arranged, and the mesh is still insufficient.

At present, TVs and refrigerators are essential electrical appliances for every family. However, there is no Internet connection function. Therefore, there is still a lot of room for the establishment of the home Internet of Things (IOT, M2M), and future Internet TV and Internet refrigerators. It may gradually become an essential electrical appliance for every family. Therefore, it is reasonable to expect that the Internet TV or Internet refrigerator should be used as a server or relay station. However, most Internet TV and Internet refrigerators will not be available in every room. Moreover, the price is not low, so it is not easy for the objects in each room of the home to form an Internet of Things with a network television or a network refrigerator as a server or a relay station. In view of this, there is a need to propose a structure that facilitates the generation of the Internet of Things through existing devices. The Internet of Things can be easily constructed in the interiors of various buildings such as homes, offices, shops, factories, warehouses, etc. The lighting source for lighting has a universal setting. Because of the regulations and lighting requirements in the building, there are light source settings within 5-10 meters. If the Bluetooth and WIFI circuits are combined with the light source or set At the light source, a mobile phone with Bluetooth and WIFI can be used as a setting and remote control device. The main structure of the Internet of Things in the building is completed, and then, if various electrical appliances or articles or personnel or pets are equipped with a Bluetooth module. Groups can naturally join the main structure of the Internet of Things as a slave node, and elastically become a member of the object.

It must be noted that the Internet of Things IOT is basically the same as M2M (Machine to Machine), so this specification treats it as a synonym. In addition, there are various versions of Bluetooth such as 2.0, 2.1, 3.0, and 4.0, which are not specified here, and therefore are applicable. WIFI also has a variety of architectures, which are not specified here, so they are applicable.

One of the ways of the present invention is to create an Internet of Things structure through an existing lighting source, and it is easy to construct an Internet of Things in various buildings such as homes, offices, shops, factories, warehouses, and the like. Because of the regulations and lighting requirements in the building, there are light source settings within 5-10 meters. The circuit of the microcontroller, Bluetooth and WIFI is combined with the light source or set at the light source to become a communication node. The main structure of the Internet of Things in the building is completed. After that, if various electrical appliances or articles or personnel or pets are equipped with Bluetooth modules, it is natural to join the IoT main architecture as a slave node and become a physical object. A member of the United Nations.

The second aspect of the present invention is to generate an Internet of Things structure through an existing lighting source, and combine a microcontroller, a Bluetooth, and a WIFI circuit with a light source or a light source to become a communication node. The main structure of the Internet of Things in the building is completed. Each room is centered on the device combining the Bluetooth master node and the WIFI. Other devices with only Bluetooth BLE in the room are regarded as slave nodes, and the communication is connected into a piconet. The communication link between the room and the room is communicated by WIFI.

The third method of the present invention is to generate the structure of the Internet of Things through the existing lighting source, and combine the circuit of the microcontroller, the Bluetooth and the WIFI into the light source or set it at the light source to become a communication node, and complete The main structure of the Internet of Things in the building, after that, with mobile communication devices with Bluetooth and WIFI such as mobile phones, laptops, tablets, etc. can be used as settings and remote control devices.

In the fourth aspect of the present invention, the structure of the Internet of Things is generated through the existing lighting source, and the circuit of the microcontroller, the Bluetooth and the WIFI is combined with the light source or disposed at the light source to become a communication node. The main structure of the Internet of Things in the building, after that, with mobile communication devices such as mobile phones, laptops, and tablets with Bluetooth and WIFI, you can connect an access point or a communication gate to connect to the Internet. Remote monitoring or cloud service computing.

The fifth aspect of the present invention is to generate the structure of the Internet of Things through the existing lighting source, and integrate the circuit of the microcontroller, the Bluetooth and the WIFI into the light source or set it at the light source to become a communication node. The main structure of the Internet of Things in the building, after which various sensors can be added to each node to construct a wireless sensor network.

In the sixth aspect of the present invention, the structure of the Internet of Things is generated through the existing lighting source, and the circuit of the microcontroller, the Bluetooth and the WIFI is combined with the light source or disposed at the light source to become a communication node. The main structure of the Internet of Things in the building, and then through the power line of the light source and power line communication (PLC) devices or facilities to build a higher transmission speed, more reliable, fault-tolerant, and more dense Internet of Things .

Due to the possible home IOT architecture, some people recommend using ZIGBEE's WSN architecture, but it is not easy to push, because almost one mobile phone is not equipped with ZIGBEE, compared with the high popularity of Bluetooth and WIFI. Rate, you can get a smoother development, as shown in Figure 1 home Internet of Things architecture, because Bluetooth is common, and low cost, and can be connected to eight devices, the general computer can have wireless Internet access, Bluetooth, WIFI, 3.5 G, or femtocell; while tablets and mobile phones are almost always equipped with WIFI and Bluetooth communication. Groups with homogeneity can be grouped through the Bluetooth Token Piconets. At home, in principle, the distance of each room will not exceed 20 meters, so the Bluetooth master node is placed at the center of the room, usually the location where the room is equipped with lights, and the furniture in the room. The device or personnel is the least likely to form an obstacle to the path of wireless communication, and the communication quality is the best. Using Bluetooth to form a star structure, each Bluetooth-equipped fixed device in the room can be used as a slave node or a slave node, and can also accommodate indoor mobile personnel or pets to install Bluetooth slave nodes. Basically, one master node can Connected to seven slave nodes into piconet.

As shown in Figure 1, electrical appliances that can interact with family members, computer peripherals, are classified into several large groups, each group gives IPv6 address function, and attaches enough wisdom to each item in the group. Set a node to be BT4.0-based, passive objects are connected by RFID, and groups and groups are mainly WiFi. In principle, the same group can specify an IPv6 address for WiFi. WiFi coexists with the main node of the Bluetooth, for example, using a company such as Broadcom or Ralink or Texas Instruments to provide a BT dual mode/WIFI direct link all-in-one chip plus a microcontroller.

Mobile phone operating system, regardless of Andorid, Windows, iOS, Sybiam, etc., can support Bluetooth or WiFi, especially if the mobile phone supports NFC function, and can read RFID tags. Of course, the RFID RFID reader can have Bluetooth communication function and directly send the reading result to the Bluetooth piconet.

In the foreseeable future, the wireless sensor of the wearable sensor equipped with indoor personnel will mainly be based on Bluetooth low-power technology. Currently, most computers and peripheral devices also have Bluetooth communication functions, which are almost everyone's. The mobile phone also has Bluetooth/WIFI communication function, so it can be connected in series and further connected to the cloud computing. Bluetooth low-power communication distance is about ten meters, enough to cover the configuration density of most indoor light sources.

The light source has Bluetooth communication to automatically detect the presence or absence of personnel. As long as the person wears a Bluetooth device, the wearable Bluetooth device refers to various items with Bluetooth communication functions, such as a belt, a wristband, or a mobile phone. The light source can be based on the presence or absence of Personnel exist, open or close. It is determined whether the Bluetooth signal is assigned by a person, mainly by the Bluetooth ID transmitted by the user, or whether the mobile object is determined by the change of the RSSI.

The BT light source should be easy to know whether it is a Bluetooth signal transmitted by a person wearing a belt or a wristband. The preferred embodiment is to let the wearable Bluetooth device have a motion sensor at the same time, if the wearable Bluetooth device The BT signal (including the motion sensor signal) is transmitted to the light source, and the program of the Bluetooth master node on the light source can determine that the user of the wearable Bluetooth device is a person, and is not moving when moving, and therefore automatically lights up Light source. Since it is necessary to receive and judge the presence of personnel at all times, it is necessary to have low power consumption. Further, by the communication strength between the mobile phone BT and the light source BT, the distance between them can be judged. Therefore, it is of course possible to provide indoor lighting control that meets the brightness requirement for the indoor person to adjust the luminosity.

Further, the home IOT can be extended to other places, such as a hospital. Since the wearable Bluetooth device has the function equivalent to active RFID, then the hospital personnel control, as long as the wearable Bluetooth device is used, in principle, each room A BT4+WIFI module is built into the light source, so as long as the patient wears a wearable Bluetooth device, the action can be effectively tracked.

The above WIFI can be selected in the WiFi Direct mode. This mode can connect to a wirelessly connected computer and printer without using a wireless base station. Therefore, through the WIFI Direct connection, a new OS can be achieved without a new OS. In contrast, ZIGBEE builds a network system that is too complicated into a node, which only increases the user's troubles and promotes it more easily. The construction of a general home network is relatively simple, and does not require an overly strict network system. As long as it is plug and play, no complicated settings are required.

The invention has the light source based internet of things, and the advantages thereof are as follows

1. It does not affect the decoration of the original room. It can set up the Internet of Things directly at any time in the old house or new house, without additional wiring.

2. There is no issue of power cord supply.

3. The light source is usually located at the center and the height of the room. The signal transmission is not easy to be obstacled. The antenna design is easy. For chandeliers and xenon lamps, it can be designed separately.

4. With RGB LED lights, you can produce a variety of color lighting.

5. Some lights can be equipped with an ambient light sensor to determine whether it is daylight or need to turn on several lights to provide intelligent and energy-saving lighting.

Referring to FIG. 2, the architecture of the IoT node light source is the backbone of the WIFI wireless communication. The part of the existing building light source is replaced by the IoT light source. The IoT light source can be divided into three types. The first pure slave node 23 is composed of a module consisting of a Bluetooth low-power chip and a microprocessor. For example, TI's TI CC2540 system single-chip, with Bluetooth 4.0 communication function, also has 8051 micro The processor, and the ADC converter, can connect eight sensing signal inputs, such as a three-axis accelerometer, a thermometer, a humidity sensor, an illuminance sensor, and a gas sensor: for carbon dioxide, carbon monoxide Sensing of formaldehyde, formaldehyde, etc., a suspended pathogen sensor that can sense influenza viruses, germs, molds, dust mites, allergens, etc., so the lamp can be deformed in various ways, allowing for suspension in the air. The object can enter the tube and be in contact with the sensor.

The second can be used as the router 21, and the WIFI and BT4.0 integrated chips can be integrated with the MCU, and the MCU is preferably selected as the ARM9. BT4.0 is used as the master node, and can directly communicate and communicate with the light source 23 or the item 20 or the movable person 22 having the slave node. Chip modules with WIFI and BT4.0 integration on the market include

(a) Atheros AR6233 the wafer using a common wireless coordination (Universal Wireless Cooperation ^TM) technology, to promote greater cooperation between the Wi-Fi and Bluetooth wireless system.

(b) Quacomm Atheros AR9004TB chip, which integrates Bluetooth 4.0 , Wifi 802.11n 2.4, 5GHz and 60GHz WiGig chipsets with a transfer rate of 5Gbps.

(c) Ralink Technology's RT3290LE wireless combo chip , 802.11n+Bluetooth 4.0 (Combo). RT3290LE introduces Ralink's unique advanced wireless coexistence (co-existence) architecture to improve the coexistence between wireless LAN and Bluetooth, and automatically adjust Wi-Fi and Bluetooth transmission based on the orientation and transmission characteristics of the surrounding AP Router. state. Not only can it effectively reduce the interference between Wi-Fi and Bluetooth, but it can further increase the peak throughput of Wi-Fi by 80%, while reducing battery power consumption.

(D) Broadcom (the Broadcom) a combination of a wireless wafer (combo) BCM4330, a single crystal film of the element integrated 802.11n Wi-Fi, Bluetooth (Bluetooth) and FM radio technology, and can support more media data application service, It does not affect the size or battery life of smartphones, tablets and other mobile devices. It has IEEE 802.11 a/b/g and single stream 802.11n (Media Access Control (MAC) / Baseband / Radio), Bluetooth 4.0+HS, FM radio receiving and transmitting functions. The BCM4330's dual-band capability allows Wi-Fi users to use the less crowded 5 GHz spectrum for media application services that require faster and guaranteed bandwidth.

(e) MediaTek MT6620 has supported many mainstream wireless communication standards on the market, including 2.4GHz and 5GHz dual-band 802.11n Wi-Fi, Wi-F Direct and Wi-Fi HotSpot, Bluetooth 4.0+HS dual-mode operation, GPS/ Galilei/SBAS/QZSS, and the company's patent-pending AlwaysLocate technology, as well as FM radio transceivers.

Compared to traditional Bluetooth radios, Bluetooth 4.0 with Bluetooth low-power wireless technology consumes only a fraction of the power. With Bluetooth low-power technology, many wireless sensor devices can operate for years with a small button-type battery, eliminating the need to replace the battery. The WIFI+BT4.0 combination chip uses Bluetooth low-power technology, so light sources, smart phones and tablets can use this combination chip to collect various sensors more effectively (such as low power consumption meter). The data transmitted by the stepper and the blood glucose monitor are connected to each other. Communication between the WIFI chip and the Bluetooth chip is achieved by a shared microcontroller.

All of the above integrated chips support Wi-Fi Direct, allowing devices to communicate directly with each other without the need to connect to access points. This not only makes communication between devices easier and faster, but it can be connected anytime, anywhere. Light sources have such a combination of chips, portable devices are no longer limited to communication in a single network, but can also easily connect between the networks, and establish one-to-one connections as needed.

The third option is to build the above BT4.0+WIFI combination chip into a home computer, PC, laptop, mobile phone, tablet computer, etc., and become a gateway 25 by its wired or wireless Internet access function. Can easily connect to cloud computing services. Because of the high-speed Bluetooth technology, this type of combined chip can use the Bluetooth application service through Wi-Fi connection and Wi-Fi Internet access. Users can use the general Bluetooth pairing technology to connect any devices that may be in their hands (ad hoc devices). For example, the BCM4330 combination chip will decide whether to connect via Bluetooth or Wi-Fi according to the available bandwidth at that time.

These combined chip products also support Android and Windows, iOS operating system phones. For example, Broadcom's OneDriver stacking software technology is a mature technology, and the source code included is part of the common Android and Windows operating system. With the BCM4330 and other Wi-Fi and Bluetooth combo products, OneDriver software can be used to make important emerging functions truly applicable to Android and Windows phones. Therefore, as long as there are mobile phones, tablets, laptops, desktop PCs, etc., people in the building can instantly record the information of various BTID people or items or sensors in the building. Provide the right to use this information for reuse.

In addition to using wireless communication such as WIFI as the communication between the Bluetooth light source (Bluetooth Primary Node) in each room and forming an Internet of Things, you can also use Power Line Communication (PLC) instead of WIFI, or as another backup. The network is mainly because the power line is the largest infrastructure; there are power outlets in every corner of the house, making it an all-encompassing network. The power line network uses a bus topology to provide a high level of reconfigurability, enabling it to control multiple devices from a single controller. The controller is able to track all devices on the network, providing a scalable and "plug and play" backbone that can be part of the network as soon as any new device is installed. As shown in Figure 3, it is the architecture diagram of the IoT node light source with power line communication as the backbone. The IoT node light source can be divided into three types: the first pure slave node (slave node) 33 is low by Bluetooth. The power chip and the microprocessor are composed of modules, such as Texas Instruments TI CC2540 system single chip, Bluetooth 4.0 communication function, 8051 microprocessor, and ADC converter, which can connect eight sensing signals. As previously stated.

The second type can be used as the router 31, and the integrated module 31 of the PLC control chip and the Bluetooth chip plus the microcontroller can be provided on the light source, and the type can be SiP or SOC. For example, Bluetooth BT4.0 is used as the master node, and can directly communicate and communicate with the light source 33 or the article 30 or the movable person 32 having the slave node. The communication between the PLC control chip and the Bluetooth chip is achieved by a shared microcontroller.

The third option is to use the BT4.0+PLC combination chip, etc., home computer, PC, laptop, mobile phone, tablet computer, etc., through the function of the Ethernet interface to become the gateway 35, so it can be easily Connect to the cloud computing service.

The IoT node module, as shown in FIG. 4 and FIG. 5, can be integrated with LED lamps or bulbs currently sold in the market, and includes an IoT node circuit board 40 composed of a TI CC2540 SOC as a center-fit sensor. It is integrated with the original LED circuit board 41 by slot or other packaging method, and the power supply of the IoT node basically shares the DC power required to drive the LED. You can further have a battery (not shown) that can be charged by the LED's power supply. When the utility power is interrupted, the IoT node can still function, especially in the event of a disaster, as emergency lighting or For communication. The light transmissive cover 42 is used to protect electronic components such as LEDs and to uniformize the illumination of the LEDs.

There are two types of LEDs, the first one is DC type, the common one is 24V/36V/48V, and a step-down rectifier circuit module is needed to convert the mains AC source into DC source 43. The current source of the IoT node module can be Directly supplied by the DC source, but it should be noted that the buck rectifier circuit should provide a 3-5V DC output. The second type is AC type. The mains supply source directly supplies the LED module. If it is to be integrated with the Internet of Things (IoT) node, it still needs a step-down rectifier circuit module 43 to convert the mains AC source into a DC source to provide the Internet of Things (IOT). Used by the node.

FIG. 4(A) shows a low wattage LED light bulb. The fixing base 45 of the LED module is made of a plastic material, and can penetrate the wireless signal of the Internet of Things node 40, and the heat dissipation structure is combined with the LED module. Figure 4 (B) is a high wattage LED light bulb, the LED module's fixing seat 46, also used as the heat dissipation structure of the LED module, so it is a metal material, can not penetrate the wireless signal of the Internet of Things node, so the object The networking node circuit board 40 is mounted above the center of the LED module circuit board 41 by the socket rise. On the one hand, the heat dissipation effect from the LED can be avoided, and on the one hand, the wireless signal can easily pass through the transparent light cover 42.

5 is an LED tube, as shown in FIG. 4, mainly including an Internet of Things node 52, an LED module circuit board 51, a carrying PCB board 53, etc., and the electrical pins 54 at both ends are standard fluorescent lamp pins.

There are three main ways to adjust the dimming function or the color grading function of the LED: the first one is a hardware mode, which can enable the SOC with Bluetooth communication function, such as the CC2540 expansion of Texas Instruments, to provide PWM function by hardware; The other is that the MCU writing firmware in the CC2540 provides PWM function. In principle, the most complicated dimming or color grading is three outputs. As long as the brightness control is performed on three RGB lights, each output is eight. The bit, the speed at which the desired color tone is driven does not need to be as fast as the motor drive, so the function of providing PWM using the firmware is a preferred embodiment that meets the requirements of use and does not increase the cost of the hardware. The hardware circuit of the dimming or color grading function includes a relay or a power transistor switch between the LED and the DC power source to receive the PWM signal.

The third type is externally connected to a PWM generator. As shown in FIG. 6, a system single chip SOC 61 having a Bluetooth communication function, such as Texas Instruments' CC2540, provides digital data required for color grading and dimming to the PWM generator 62. The PWM signal is fed into the LED driving circuit 63 to perform color adjustment and dimming of the LED module 64. The AC power source 67 is 110-220V, and the AC-to-DC circuit module 66 is converted into a DC voltage source V _DD 68.

As shown in FIG. 7, a universal light bulb adapter 120 has an AC-DC circuit module 122 built therein. The wireless communication module 124 serves as a node of the Internet of Things, and its input end is an E27 standard light bulb connector. 125. The power supply of the general building is 110-220V. Therefore, it is necessary to provide an AC-to-DC circuit module, which mainly provides a 2-5V DC power supply to the wireless communication module 124.

Further, the dimming or coloring circuit module 126 is added to the universal light bulb adapter 120, and the other output terminal is also an E27 standard light bulb connector 128, which can be connected to the LED bulb 129.

The advantage of this is that if the LED light source fails to be discarded, the built-in wireless communication module (Internet of Things node) 124 of the universal light bulb adapter 120 does not have to be discarded.
