The invention relates to a wireless network relay device and a wireless network relay system including the wireless network relay device, in particular, it can be connected, converted and connected in different wireless communication protocols in a wireless network A wireless network relay device for wirelessly exchanging data between, and a wireless network of a wireless network relay system including the wireless network relay device.

Due to the rapid development and proliferation of electronic and wireless communication technologies, a variety of electronic devices and systems based on wireless communication have been created, which have become practical and very popular. These electronic systems are composed of various possible wireless electronic devices, such as : Smart phones, wearable devices, Internet of Things (IoT), home automation devices, home security devices, wireless audio devices, tablet devices, wireless sensors, wireless sensors, wireless transducers, wireless actuators, mobile Devices, etc. These wireless devices can use different data formats to communicate and exchange data with each other, or with other electronic devices or network devices to communicate and exchange data with each other. These data formats include, for example: audio, video, Sound, text, video, etc. Generally speaking, these wireless devices have become more and more common in today's society.

Some of these wireless devices are in a limited range, such as: at home, school, dormitory, laboratory, office, or building, or a relatively small area, and with two or more The wireless devices are wirelessly connected to each other. This part of the devices usually relies on short links, also known as short-range or short-range wireless communication technologies, such as Wi-Fi technology, Bluetooth low-power technology, Zigbee technology, Sub-1GHz technology, etc., to establish a wireless personal area network (WPAN), or a wireless local area network (WLAN), to establish wireless communication between various devices in this part, of which wireless personal area network The circuit is mainly used to connect multiple personal consumer electronics products wirelessly, and the wireless local area network is used to connect multiple basic network components, such as: base stations, stations (STAs), nodes (nodes), hubs ( hubs), etc., wirelessly connected together.

Figure 1 reveals a simple network topology of a conventional basic wireless local area network based on Wi-Fi communication technology; the wireless local area network 100 includes a base station 102, a first node 110, a second node 120, a third node 130, The fourth node 140 and so on, the base station 102 is a network device (network device), which may be a wireless network access point (AP), or a router (router), which is through a wired network 105, for example: Ethernet Ethernet (Ethernet), directly connected to the wired network service provided by the Internet Service Provider (ISP) 104, the base station 102 thus acts as a wireless access point and can provide a wireless transmission covering the wireless transmission distance 103 for use Wireless devices with the same wireless protocol can wirelessly access wired network services.

Specifically, the base station 102 is a Wi-Fi access point using a standard Wi-Fi communication protocol, for example: IEEE 802.11b, and the first node 110 is a wireless device using the same standard Wi-Fi communication protocol as the base station 102 For example, a remote view door phone or an electronic lock, which is deployed within the wireless transmission distance 103 of the base station 102, and the second node 120 uses the same standard as the base station 102 Wi-Fi protocol wireless devices, such as laptop computers, but with an extra long-range Wi-Fi antenna, although the second node 120 appears to be the effective communication range of the wireless transmission distance 103 deployed in the base station 102 In addition, it can still collect and sense the radio frequency radio waves from the base station 102 by using a long-range Wi-Fi antenna to establish wireless communication with the base station 102.

However, the third node 130 and the fourth node 140 cannot establish wireless communication with the base station 102, although the third node 130 appears to be within the wireless transmission distance 103 of the base station 102, and the third node 130 is within the wireless transmission distance 103 , But because it uses the Bluetooth Low Energy (BLE) protocol as a short-range wireless communication technology, before the third node 130 is connected to the base station 102, the BLE protocol needs to be converted into a Wi-Fi protocol, and the fourth node 140 It is obviously located outside the wireless transmission distance 103 of the base station 102, and uses Zigbee communication technology with a relatively smaller and shorter transmission distance than the wireless transmission distance 103 to transmit data, so that the fourth node 140 cannot be outside the wireless transmission distance 103 , And establish wireless communication with the base station 102 based on the Wi-Fi agreement.

Although Wi-Fi technology and Bluetooth technology both use certain radio waves of the same frequency, these two communication technologies, after all, use completely different wireless protocols and require different hardware and software configurations to function properly. Furthermore, Wi-Fi technology is usually limited to the transmission and reception of data within a range of less than 100 meters, while Bluetooth technology is limited to a range of less than 10 meters. In addition, when different communication technologies coexist in the same wireless area In the network, these communication technologies have different transmission distances or ranges, and use different communication protocols to exchange data. Therefore, it is necessary to convert appropriate communication protocols between various communication technologies.

Basically, various short-range wireless communication technologies, such as Wi-Fi technology, Bluetooth low-power technology, Zigbee technology, Sub-1GHz technology, etc., have their own characteristics and advantages, making these technologies suitable for different applications. Occasions and wireless devices, for example, some wireless devices such as the fourth node must obtain power from the internal battery to operate, so these wireless devices will be limited to the use of low-power wireless communication technologies, such as Bluetooth Low power consumption (Bluetooth low energy, BLE) technology leads to a relatively short effective transmission distance, but today it seems very common that in the same wireless local area network, each wireless device uses a different wireless communication technology .

Bluetooth is a wireless communication technology standard. It uses short-baud high-frequency (UHF) radio waves to achieve data exchange within a short distance. UHF radio waves are a series of ISM (industrial, scientific, Medical) RF radio waves operating in the 2.4GHz to 2.485GHz frequency band, which also includes guard bands with a bandwidth of 2MHz and 3.5MHz at the bottom and top, respectively, to avoid interference. Bluetooth is often used in fixed and mobile devices. A small-area communication network such as a wireless local area network (WLAN), a small wireless personal area network (PAN), or an ad hoc network can be established between multiple mobile devices.

Bluetooth technology is best known for its frequency-hopping spread spectrum technology, which transmits radio wave signals by quickly switching carriers in many channels, which can effectively resist narrow-band interference and minimize it as much as possible. Interference, the realization of which is now widely seen in wireless devices such as smartphones, game consoles, wireless audio devices, tablet devices, notebook computers, wearable devices, wireless sensors, wireless sensors and other wireless devices. .

Since its development, there have been many versions of the Bluetooth standard, but the latest version can cover all the old versions. Among the various Bluetooth standard versions, the most noticed version is the Bluetooth 4.0 version, and the Bluetooth 4.0 version began to be imported. The implementation of low power consumption, Bluetooth 4.0 version plus low power consumption is usually called BLE (Bluetooth low energy), usually the Bluetooth 4.2 version and older versions have a physical transmission distance of less than 10 meters indoors, but are open outdoors The transmission distance of the field is about 200 meters, but the Bluetooth 5.0 version claims that the outdoor open field transmission distance is greater than the physical transmission distance of 40 meters to 400 meters.

Wi-Fi has become the most widely used wireless communication technology in the world. With the use of devices that comply with the IEEE 802.11 standard and the establishment of a wireless local area network (WLAN), Wi-Fi is basically the brand name of IEEE 802.11 related technologies. IEEE 802.11 is a set of specifications that regulate data communication between the media access control (MAC) layer and the physical layer. In the open system interconnection reference model (OSI) architecture, the MAC layer is the data The sub-layer of the connection layer (layer 2), the physical layer is directly the first layer of the OSI architecture.

In most home and office occasions, almost all use Wi-Fi as a wireless access point (AP), so that laptops, printers, smartphones and other devices can communicate with each other wirelessly (wireless/cordless) Communicate or exchange data and connect to the Internet without connecting any wires or cables. Wi-Fi uses short-baud high-frequency (UHF) and short-wave ultra-high frequency (SHF) radio frequency waves. Working in the 2.4GHz and 5.8GHz ISM bands, usually Wi-Fi routers (routers) or access points (APs) have indoor transmission distances of approximately 10 meters, 30 meters, and 100 meters, and open fields outdoors The domain will have a better transmission distance. If it is aimed at an indoor environment, it is generally considered that Wi-Fi can provide a relatively long transmission distance.

As for IEEE 802.11, it is basically a family set consisting of multiple protocols that involve a series of half-duplex over-the-air modulation techniques, all of which use the same The basic agreement, and it is represented by the suffix of different letters or numbers after "IEEE 802.11". For example, IEEE 802.11-1997 is the first wireless network protocol in the family collection, and IEEE 802.11b is the first. A protocol widely accepted by consumers, and others such as IEEE 802.11a, IEEE 802.11g, IEEE 802.11n, and IEEE 802.11ac are also widely popular agreements. If IEEE appears on a Wi-Fi wireless device The 802.11 b/g/n specification indicates that Wi-Fi wireless devices can manage and be compatible with IEEE 802.11b, IEEE 802.11g, and IEEE 802.11n protocols at the same time.

Zigbee refers to a set of high-level communication protocols based on the IEEE 802.15.4 specification, which is dedicated to providing low-cost, low-power, short transmission range, and low data with a small-scale, low-power digital radio A wireless data transmission technology featuring speed, low latency, low signal interference, and close range to establish a wireless local area network (WLAN), wireless personal area network (PAN), or wireless random network between multiple devices Ad hoc network, etc., provide applications such as: home automation, medical device data collection, vital signs collection, and other low power consumption and low frequency bandwidth.

Usually Zigbee is aimed at wireless devices used in battery-powered, wireless control and wireless monitoring applications, and mainly operates in the ISM band distributed at 2.4GHz and below Sub 1GHz, according to each country or autonomous region (jurisdictions) Different regulations, basically the 2.4GHz frequency band is applicable globally, and the sub-1GHz frequency band includes the 868.3MHz band allowed in the European Union, the 916.8MHz band allowed in the United States, the 784MHz band allowed in China, etc. Zigbee is indoors The transmission distance is about 10 meters to 20 meters. In most countries and autonomous regions, the sub-1GHz frequency band can be used and operated without a license or permission.

For short-range, low data rate, and indoor-based communication applications, especially for low data transmission rate applications, Sub 1GHz radio frequency (RF) technology, which has not been fully standardized globally, is another alternative. Sub 1GHz radio frequency is usually Refers to the radio frequency working in the ISM spectrum below 1GHz, usually using the frequency bands of 769MHz to 935MHz, 315Mhz, and 468Mhz. Sub1GHz radio frequency mainly uses the radio frequency below 2.4GHz, compared with the radio frequency of 2.4GHz. The relatively low diffraction loss (diffraction loss), so the frequency band below the 1GHz spectrum is particularly suitable for applications involving indoor wireless communications, such as: home automation, home security, etc.

The ISM frequency band is defined and managed by the International Telecommunications Union (ITU), and is reserved worldwide for radio frequency applications for industrial, scientific, and medical purposes, as long as it is used to perform relevant industrial, scientific, and medical purposes Any device can freely use the ISM band for unlicensed operations without a license or permission. The ISM band covers several of the most commonly used bands, including 2.4GHz and 5.8GHz bands.

In this embodiment, the first communication module 210 preferably uses a short-range wireless communication technology, which is a short-range wireless communication technology relative to the wireless communication technology of the second communication module 220 to provide low power Wireless communication and establish a wireless personal area network (WPAN) or a wireless local area network (WLAN), the short-range wireless communication technology used by the first communication module 210 is preferably: Bluetooth Low Energy (BLE) )Wireless communication technology, Bluetooth 4.0 wireless communication technology, Bluetooth 4.1 wireless communication technology, Bluetooth 4.2 wireless communication technology, Bluetooth 5.0 wireless communication technology, Zigbee wireless communication technology, Sub-1GHz wireless communication technology, infrared wireless transmission technology, Household radio frequency technology, or ultra-wideband wireless communication technology, etc.; the second communication module 220 preferably uses a long-distance wireless communication technology, which belongs to the long-distance wireless communication relative to the wireless communication technology of the first communication module 210 Technology, which is used to provide wireless communication with high data transmission rate and establish a wireless local area network (WLAN).

For example, the first wireless protocol is preferred It is the Bluetooth Low Energy (BLE) protocol, and the second wireless protocol is preferably the Wi-Fi protocol. Although the Bluetooth protocol and the Wi-Fi protocol both use some radio waves of the same frequency, these two The protocol profiles are completely different, and each requires different hardware and software configurations to function properly. Therefore, when messages and data are to be exchanged between the first communication module 210 and the second communication module 220 using different wireless protocols, respectively Or signal, it is necessary to implement protocol conversion between the first communication module 210 and the second communication module 220.

The power supply module 250 is the first communication module 210, the second communication module 220, the protocol conversion module 230, the processor 240, the communication module 260 and other circuits included in the wireless network relay device 200. The components provide power, and the power supply module 250 receives power from a power grid by connecting a power plug to, for example, a wall power outlet, and then receives the voltage of the received power After the current characteristics are converted, modulated, and processed to a degree suitable for the use of various circuits and components in the wireless network relay device 200, it is further transferred to the first communication module 210 in the wireless network relay device 200 , The second communication module 220, the protocol conversion module 230, the processor 240, and the communication module 260.

In some embodiments, the communication module 260 is preferably an optional component. When the communication module 260 uses the first wireless protocol in the first communication module 210 or the second wireless in the second communication module 220 When the same wireless protocol is agreed, the first communication module 210 or the second communication module 220 can be used as the communication module 260 instead of the communication module 260. In this case, the wireless network relay device 200 can be used The communication module 260 as an optional element is omitted in the.

FIG. 3 is a schematic diagram illustrating an exemplary embodiment of a wireless network relay system of the present invention including a wireless device and a wireless network relay device of the present invention. The wireless network relay device of the present invention connects a wireless device To a network device, and convert and forward data between a wireless device and a network device; the wireless network relay system 300 of the present invention includes a wireless network relay device 200, a network device 310, and a wireless device 320, a network device 310, also known as network equipment, networking hardware, or network connection device, is basically a physical device that is used to provide wireless device 320 with the ability to connect to the network and connect data from the wireless The device forwards to the network, or filters data traffic to accelerate the flow of data on the network, or to ensure the smooth flow of data in the network. Generally, the network device 310 has a relatively long transmission range. In this embodiment, the network The device 310 is preferably a wireless access point (AP), a router, a hub, or a gateway, and has a network device communication range 311. The network device 310 provides the necessary networking capabilities to access the network. The network refers to, for example: wired network, Internet, local area network (LAN), wireless personal network (WPAN), wireless local area network WLAN, Wi-Fi network, or wireless sensor network.

The wireless device 320 is an electronic physical device with a specific purpose or multiple functions, and is embedded with a communication module that executes a wireless communication protocol, so that the electronic physical device can be connected to a network or exchange data with another wireless device. Basically The wireless device 320 may be any electronic device embedded with a wireless communication module. In this embodiment, the wireless device 320 is preferably an electronic device equipped with short-range wireless communication technology, such as a Bluetooth device, a wireless sensor, Wireless sensors, wireless transducers, wireless actuators, smart devices, IoT devices, electronic locks, cameras, motion sensors, smart switches, door sensors, indoor alarms, outdoor alarms, smoke detectors, water leaks Detector, or RF remote control, etc.

The wireless device 320 operates by receiving power from an internal battery or receiving fixed power from an external power network. However, in some cases, the wireless device 320 may not receive fixed power or may not need to use fixed power because The wireless device 320, such as an electronic lock, may just be deployed at a location away from the wall plug, or there is no wall plug at all so that it cannot obtain fixed power from the power network, or the wireless device 320 is a wearable device such as a Bluetooth headset, Therefore, it is not suitable for use and access to fixed power, or the wireless device 320 may be just a simple wireless sensor, or an actuator, etc., such as a smoke sensor, which only consumes a small amount of power to operate, start, And report a small amount of data to the user.

For this type of wireless device 320, since the internal battery is the only source of power, a wireless communication module that implements a wireless communication technology with low power consumption, but low data transmission rate and relatively short transmission distance is built into the wireless device 320 The first choice in the world, in fact, many wireless devices 320 are installed with short-range wireless communication modules. However, although short-range wireless communication technology is sufficient to provide wireless device 320 to transmit and receive data, it is best to ensure that network device 310 will always It can be located very close to the wireless device 320, or it can be located within the short transmission range of the wireless device 320.

At least two problems occur and actually occur here. The first problem occurs when the network device 310 that provides networking capability to the wireless device 320 is too far away from the wireless device 320 or the short-range wireless communication is located in the wireless device 320 When the communication range of the technology is out of range, the wireless device 320 will lose all communication with the network device 310. The second problem is that the wireless protocol used by the short-range wireless communication technology on the wireless device 320 is very likely to communicate with the network. The wireless protocol used by the long-distance wireless communication technology on the device 310 is different.
