Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The networking is tedious and is an important factor for limiting the application of the Internet of things technology in the field of intelligent environments. When a terminal device joins a local area network (such as a LoRa network), the following three important parameters are required in addition to some conventional configuration parameters: the local area network name (which may be referred to as appui), channel, and device unique identity (which may be referred to as DEVEUI). In which the appui of all terminal devices mounted under the same gateway must be consistent with the gateway, and the terminal device can communicate with the gateway. Also, there are usually multiple channels under one network for frequency hopping communications, for example, the same LoRa network generally has 8 channels, and the multiple channels of all terminal devices under the same network (local area network) must be identical. In addition, the gateway must also know that the DEVEUI of the terminal device is able to communicate with the terminal device. In the prior art, when the terminal equipment is added into the local area network, the operation of obtaining and changing the configuration parameters is complex and tedious, and the application of the configuration parameters is limited.
In order to solve the technical problem, the embodiment of the utility model provides a terminal equipment's networking system based on thing networking is proposed. Fig. 1 shows an architecture diagram of a networking system of a terminal device based on the internet of things according to an embodiment of the present invention. Referring to fig. 1, the system may include: terminal device 110, gateway 120, remote control center 130, and application client 140. The gateway 120 is connected to the remote control center 130 through the internet. The application client 140 may be mounted on a mobile terminal (e.g., a mobile phone, a tablet computer, etc.), and connected to the remote control center 130 in a wireless manner. The terminal device 110 is provided with an information code including a device model and a device unique identity (DEVEUI) of the terminal device. The information code may be a bar code or a two-dimensional code.
It should be noted that fig. 1 shows a plurality of terminal devices 110 according to a scenario of a general practical application, where a solid-line double-headed arrow connects a terminal device 110 and a gateway 120, which indicates that the terminal device 110 and the gateway 120 have successfully established a networking connection; when the terminal device 110 and the gateway 120 are connected by a dashed double-headed arrow, it indicates that the terminal device 110 is to establish networking connection with the gateway 120, that is, the terminal device 110 is a terminal device to be networked.
After the terminal device 110 is installed and powered on, and when a networking connection is to be established with the gateway 120, the application client 140 scans an information code of the terminal device 110 to be networked to obtain a device model and a device unique identity of the terminal device 110, and uploads the obtained device model and device unique identity of the terminal device 110 to the remote control center 130.
The remote control center 130 receives the device model and the device unique identifier of the terminal device 110, and issues the received device model and the device unique identifier of the terminal device 110 to the gateway 120. Further, the gateway 120 establishes a networking connection with the terminal device 110 by specifying a local area network communication standard according to the received device model and the device unique identity of the terminal device, thereby completing the network access operation of the terminal device 110.
In an alternative implementation of the embodiment of the present invention, as shown in fig. 2, the number of gateways 120 may be multiple. In this case, each gateway 120 may mount (or be connected to) a plurality of terminal devices 110, and each gateway 120 and the plurality of terminal devices 110 connected thereto form a local area network, so that the entire system forms a plurality of local area networks, thereby ensuring the communication efficiency between the gateway and the terminal devices to the maximum extent. At this time, the remote control center 130 may further match the terminal device 110 with the plurality of gateways 120 according to a preset matching rule according to the received device model and the device unique identifier of the terminal device, and issue the device model and the device unique identifier of the terminal device 110 to the matched gateways 120. Further, the matched gateway 120 establishes a networking connection with the terminal device 110 according to the received device model and the device unique identity of the terminal device, and completes the network access operation of the terminal device 110. The preset matching rule mentioned here may include matching the terminal device with a gateway having a small number of mounted terminals, specifying a gateway connected to the terminal device by a user, and the like. It should be noted that when there are multiple gateways, the gateway 120 interacting with the terminal device 110 refers to a gateway matching the terminal device 110.
In a preferred implementation of the embodiments of the present invention, as shown in fig. 2, each gateway 120 may include a location module 121. The Positioning module 121 may acquire the location information of the gateway through a Global Positioning System (GPS) or the like, for example. The obtained location information of the gateway can be uploaded to the remote control center 130 by the gateway 120, can be used as one of analysis bases for matching the terminal device and the gateway, and can also provide bases for asset management and fault location. The application client 140 may also obtain the location information of the terminal device 110 to be networked and upload the location information of the terminal device to the remote control center 130. In this case, when the terminal device is matched with the gateway in the network access process of the terminal device, the remote control center 130 may match the terminal device 110 with the gateway 120 closest to the terminal device according to the received device model, device unique identifier and location information of the terminal device 110. The location information mentioned herein may be expressed in terms of latitude and longitude. Preferably, when the terminal device and the gateway are matched, the number of the mounted terminals of the gateway is also considered at the same time, so as to balance the region and the load distribution.
In an optional implementation of the embodiment of the present invention, the specified lan communication standard interacted between the gateway 120 and the terminal device 110 may be an LoRa standard. Accordingly, as shown in fig. 2, each terminal device 110 is provided with an LoRa communication module 111, and accordingly, the gateway 120 is provided with an LoRa communication module 122, and interaction between the terminal device 110 and the gateway 120 is realized through the LoRa communication module 111 and the LoRa communication module 122. The Long Range Radio (Long Range Radio) is a low power consumption local area network wireless standard, realizes the unification of low power consumption and Long distance, and can enlarge the distance by 3-5 times compared with the traditional wireless Radio frequency communication distance under the same power consumption, thereby obviously increasing the effective communication transmission distance between the terminal equipment and the gateway.
Further, in order to improve the success rate and efficiency of network access of the terminal device, in a preferred embodiment, still referring to fig. 2, the LoRa communication module 122 of the gateway 120 includes a first LoRa communication module 1221 for network access management of the terminal device and a second LoRa communication module 1222 for communication after networking with the terminal device. The communication configuration parameters of the first LoRa communication module 1221 may be set as factory default parameters, and these parameters are consistent with the communication configuration parameters of the terminal device 110 to be networked when the terminal device leaves the factory and is not networked, so that the first LoRa communication module 1221 may be configured to receive information sent by the terminal device 110 that is not networked. The communication configuration parameter of the second LoRa communication module 1222 may be set as a parameter of the local area network where it is located.
After receiving the device model and the unique device identity of the terminal device 110 sent by the remote control center 130, the gateway 120 sends a command carrying the communication configuration parameters of the second LoRa communication module 1222 to change the communication configuration parameters to the terminal device 110 through the first LoRa communication module 1221. After receiving the command for changing the communication configuration parameters, the terminal device 110 changes its own communication configuration parameters to be consistent with the communication configuration parameters of the second LoRa communication module 1222, so as to join the local area network of the second LoRa communication module 1222 of the gateway 120. The communication configuration parameters referred to herein may include a local area network name and/or a channel.
Further, the application client 140 may further obtain factory default communication configuration parameters of the terminal device 110 to be networked and upload the factory default communication configuration parameters of the terminal device to the remote control center 130. The remote control center 130 then issues the received factory default communication configuration parameters of the terminal device 110 to the gateway 120. In actual operation, the application client 140 may upload the acquired device model, the device unique identifier, and the factory default communication configuration parameter of the terminal device 110 to be networked to the remote control center 130. Then, the remote control center 130 issues the received device model, the device unique identifier, and the factory default communication configuration parameter of the terminal device 110 to the gateway 120. In this case, after receiving the device model, the unique device identity, and the factory default communication configuration parameter of the terminal device 110, and before sending a command for changing the communication configuration parameter to the terminal device 110, the gateway 120 sets the communication configuration parameter of the first LoRa communication module 1221 to be consistent with the factory default communication configuration parameter of the terminal device 110, so that the gateway 120 may interact with the terminal device 110 through the first LoRa communication module 1221. After the terminal device 110 joins the local area network in which the second LoRa communication module 1222 is located, the gateway 120 restores the communication configuration parameters of the first LoRa communication module 1221.
In practical applications, the terminal device 110 generally provides power in the following two ways: firstly, the commercial power is supplied, and for the terminal equipment adopting the commercial power, the electric quantity is supplied stably, and the bearable power consumption is relatively high; secondly, battery-powered terminals, such as terminals powered by solar energy, or by a battery, suffer from relatively low power consumption for terminal devices that are battery-powered, the amount of power supplied being dependent on the amount of power stored in the battery.
In an optional implementation of the embodiment of the present invention, the terminal device 110 may be configured to:
when terminal device 110 is a battery-powered terminal device, communicating with gateway 120 in a first communication mode (Class a communication mode not referred to as LoRa); when the terminal device 110 is a mains-powered terminal device, a second communication mode (Class C communication mode, which is not referred to as LoRa) is used to communicate with the gateway 120. In the first communication mode, the gateway 120 performs downlink communication with the terminal device 110 in response to the uplink transmission signal only after the terminal device 110 transmits the uplink transmission signal to the gateway 120, that is, at any time, the downlink communication of the gateway can only be performed after the uplink communication of the terminal device. In the second communication mode, the terminal device 110 always opens the receiving window so that the gateway 120 performs downlink communication with the terminal device 110, that is, the gateway may issue data to the terminal device in real time. By enabling the battery-powered terminal equipment to work in the first communication mode, the power consumption of the battery-powered terminal equipment can be minimized during application, and meanwhile, the gateway can respond quickly to perform downlink communication with the battery-powered terminal equipment.
Based on the above communication mode configuration of the terminal device 110, after receiving the device model and the device unique identifier of the terminal device 110 sent by the remote control center 130, the gateway 120 may further determine the type of the terminal device 110 according to the received device model of the terminal device 110. If the terminal device 110 is a terminal device powered by the commercial power, the gateway 120 immediately sends a command carrying the communication configuration parameter of the second LoRa communication module 1222 to change the communication configuration parameter to the terminal device 110 through the first LoRa communication module 1221. If the terminal device 110 is a battery-powered terminal device, after receiving the information reported by the terminal device 110 through the first LoRa communication module 1221, the gateway 120 sends a command carrying the communication configuration parameter of the second LoRa communication module 1222 to the terminal device 110 through the first LoRa communication module 1221 to change the communication configuration parameter. After receiving the command for changing the communication configuration parameters, the terminal device 110 changes its own communication configuration parameters to be consistent with the communication configuration parameters of the second LoRa communication module 1222, so as to join the local area network of the second LoRa communication module 1222 of the gateway 120.
In a preferred implementation of the embodiment of the present invention, in order to improve the success rate of communication between the terminal device and the gateway, referring to fig. 2, the LoRa communication module 122 of the gateway 120 may further include a third LoRa communication module 1223. The third LoRa communication module 1223 may serve as a backup communication module for the second LoRa communication module 1222. After the terminal device 110 establishes the networking connection with the corresponding matched gateway 120, if the number of times that the terminal device 110 does not receive the response information of the second LoRa communication module 1222 of the gateway 120 after reporting the information to the gateway 120 exceeds the specified number of times of non-response, or the communication success rate of the terminal device 110 and the second LoRa communication module 1222 of the gateway 120 is smaller than the first preset threshold, the communication configuration parameter of the terminal device 110 is automatically changed to be consistent with the communication configuration parameter of the third LoRa communication module 1223 of the gateway 120, and the terminal device communicates with the gateway 120 through the third LoRa communication module 1223. The specified number of times of non-response mentioned here may be set to, for example, 5 times, 10 times, etc., and the first preset threshold may be set to, for example, 80%, 85%, etc., without limitation.
Considering that a plurality of terminal devices are mounted under each gateway, in order to avoid data collision between different terminal devices when the terminal devices report information to the gateway, a plurality of terminal devices 110 under the same gateway 120 may report in a sequential round-robin manner. Specifically, each terminal device 110 may be allocated a respective time window in a round-robin cycle, the time windows are connected in sequence, and each terminal device 110 completes operations of reporting information to the gateway 120 and receiving data sent by the gateway 120 in the respective corresponding time window at regular time, thereby greatly enhancing the order and success rate of communication between the terminal device and the gateway.
More preferably, after the terminal device 110 establishes the networking connection with the corresponding matched gateway 120 and before reporting the information, it may also be determined whether the data size of the information to be reported exceeds a second preset threshold. If the data volume of the information to be reported exceeds the second preset threshold, the terminal device 110 automatically changes its communication configuration parameter to be consistent with the communication configuration parameter of the third LoRa communication module 1223 of the gateway 120, and communicates with the gateway 120 through the third LoRa communication module 1223. By switching the network to the network where the third LoRa communication module of the gateway is located before the terminal device performs large data volume communication, the pressure of the second LoRa communication module can be reduced. Especially for the situation that the terminal equipment adopts the round robin reporting, the embodiment prevents the round robin reporting mechanism of the terminal equipment under the network where the second LoRa communication module of the gateway is located from being disturbed by long-term communication, and ensures the orderliness and the effectiveness of communication.
The utility model discloses in an optional implementation scheme of embodiment, the utility model provides a networking system based on terminal equipment of thing networking can also be applied to outdoor lighting terminal equipment's networking occasion to make the lighting terminal equipment of outdoor region (like district, courtyard, garden, village, campus, park etc.) can conveniently be connected with corresponding gateway and remote control center and form thing networking topological structure, and then realize the purpose to the remote measurement and control of outdoor lighting lamps and lanterns. At this time, the plurality of terminal devices 110 may be outdoor lighting terminal devices including, but not limited to, street lamps, garden lamps, lawn lamps, landscape lamps, environmental sensors, and the like. The environment sensor mentioned here may be a composite sensor component having a sensing function of measuring environmental information such as temperature, humidity, air pressure, light, noise, VOC (Volatile Organic Compounds), PM2.5, and the like in the environment, and a wireless communication function.
In an optional implementation of the embodiment of the present invention, the gateway 120 may further be provided with a wan communication module 123 for communicating with the remote control center 130 via the internet through wan communication technology. That is, the wan communication module 123 serves as an upstream communication interface of the gateway 120, and functions to connect the lan with the remote control center 130. The wide area network communication technology mentioned herein may include one of general packet radio service GPRS, third generation mobile communication technology 3G, fourth generation mobile communication technology 4G, internet access communication, etc. Portal communications access the internet by utilizing a network interface (e.g., an ethernet interface, etc.).
Use the communication scene schematic diagram during the terminal equipment network deployment that fig. 3 shows according to the utility model discloses a specific embodiment as an example below, right the utility model provides a network deployment operation of terminal equipment carries out specific explanation.
Referring to fig. 3, after the terminal device 110 is installed and powered on, the application client 140 scans an information code of the terminal device 110 to obtain a device model and a device unique identity (DEVEUI) of the terminal device, further obtains location information of the terminal device 110, and uploads the device model, the DEVEUI, and the location information of the terminal device 110 to the remote control center 130. The remote control center 130 performs comprehensive analysis according to the received information, matches the terminal device 110 with a suitable gateway 120 according to a matching rule that the distance between the terminal device and the gateway is short and the number of mounted terminals of the gateway is less as priority, and issues the device model, DEVEUI, and location information of the terminal device 110 to the matched gateway 120. After receiving the above information, the gateway 120 determines the type of the terminal device 110. Since the communication configuration parameter (or network parameter) of the first LoRa communication module 1221 of the gateway 120 has been preset to be consistent with the default parameter of the terminal device 110 when the terminal device is shipped from factory and not networked, the first LoRa communication module 1221 may be used for communication between the gateway 120 and the non-networked terminal device 110. For the terminal device 110 powered by the commercial power, the gateway 120 immediately sends a command carrying the communication configuration parameters of the second LoRa communication module 1222 to change the communication configuration parameters to the terminal device 110 through the first LoRa communication module 1221. For the terminal device 110 powered by the battery, after receiving the information reported by the terminal device 110 at regular time through the first LoRa communication module 1221, the gateway 120 sends a command carrying the communication configuration parameter of the second LoRa communication module 1222 to the terminal device 110 through the first LoRa communication module 1221 to change the communication configuration parameter. After receiving the command for changing the communication configuration parameters, the terminal device 110 changes its own communication configuration parameters to be consistent with the communication configuration parameters of the second LoRa communication module 1222, so as to join the local area network of the second LoRa communication module 1222 of the gateway 120.
The terminal equipment is added into the local area network by adopting a code scanning mode, and the problems of complex and fussy operation of adding the equipment into the gateway in the existing LoRa communication technology are solved.
