In addition, in the description of the present application, unless otherwise indicated, "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
The Bluetooth MESH network is a low-power Bluetooth network topology for establishing communication of many-to-many devices, and the devices can mutually carry out information data transfer. In the bluetooth MESH network, a device that does not join the bluetooth MESH network is generally called an unassigned device, and the unassigned device joins the bluetooth MESH network and is called a node.
The nodes in the Mesh network can be classified into various applications such as sensors, lamps, gateways and relays according to application functions, and can be classified into normal electric equipment and low-power-consumption equipment according to power supply modes, wherein the low-power-consumption equipment is in a long-time dormant state in the Mesh network, a Friendship relation needs to be established with the normal electric equipment, network information is processed regularly, and therefore an adv packet cannot be monitored for a long time. The nodes in the invention adopt common electric nodes, namely non-low-power-consumption nodes.
The invention discloses a passive wireless switch control method based on a Bluetooth MESH network, which at least comprises network access binding and control distribution, and specifically comprises the following steps:
network entry binding: at least one node of the Bluetooth MESH network is selected as a monitoring node, the monitoring node monitors an adv packet broadcast by the passive wireless switch, analyzes the adv packet and stores the adv packet, and the monitoring node also stores configuration information.
Specifically, the network access binding means that one or more nodes in the Bluetooth Mesh network are set to monitor adv packets broadcasted by the passive wireless switch. The adv package is usually an unconnected custom adv package, and the following information can be obtained after the adv package is parsed: information such as MAC address, device identification type code, vendor identification code, key code, etc. The listening node stores configuration information matched with the adv packet, wherein the configuration information is that the passive wireless switch is associated with the actual control operation, namely, the configuration information is a translation rule, and the translation rule can comprise an operation identification code (namely, the adv corresponding to each key of the passive wireless switch), a response target range (such as a single device or multiple devices or a logic group), a response action (such as turning on a lamp or adjusting to 60% brightness), and a response additional operation (such as delay response time, response operation gradual change time and the like). When the monitoring node monitors the ADV packet of the passive wireless switch, the monitoring node analyzes the ADV packet, and if the analyzed MAC address, the equipment identification type code, the manufacturer identification code, the key code and the like are matched with the stored configuration information, the subsequent translation step is carried out according to the key code and specific rules.
The number of keys of the passive wireless switch is determined according to the physical structure, one or more keys are possible, and the specific functions realized by the keys are realized by configuration information, and can be customized. When the passive wireless switch joins the Bluetooth MESH network for the first time, the configuration information stored in the monitoring node is default configuration information, and the key function is default function.
When network access binding is required, the selected listening node requires a trigger binding operation, including but not limited to: triggering a physical button on the monitoring node, an operation button on the App, or a power-on again, etc. After the monitoring node triggers the binding operation, the monitoring node performs a searching operation within a preset time length to monitor the passive wireless switch. At this time, the passive wireless switch performs a network access operation, where the network access operation may be that at least one designated key of the passive wireless switch is pressed (for example, two designated keys are pressed simultaneously to avoid false touch), and then the passive wireless switch may send an adv packet. The monitoring node receives the adv packet for analysis and storage. The monitoring node can prompt the user to complete network access binding in the modes of flashing lights, reporting App to pop windows, changing brightness or color and the like.
And (3) control distribution: the monitoring node receives and analyzes the adv packet broadcast by the passive wireless switch, translates according to the stored configuration information to obtain a Bluetooth MESH data packet, forwards the Bluetooth MESH data packet in a Bluetooth MESH network, forwards the Bluetooth MESH data packet after receiving the Bluetooth MESH data packet by non-target equipment, and responds to actions after receiving the Bluetooth MESH data packet by the target equipment.
Control distribution refers to how a target device receives and responds when a passive wireless switch is pressed. In the control distribution, the listening node also listens for an adv packet broadcast by a control operation of the passive wireless switch, which may be pressing a key on the passive wireless switch. The types of data that the passive wireless switch broadcasts in the control distribution and the ad packets broadcast in the network-access binding may be the same and the specific content may be different.
Specifically, when a user presses a certain key of the passive wireless switch which is already connected with the network, the passive wireless switch sends an adv packet, the monitoring node receives and successfully analyzes the adv packet, translates the adv packet according to stored configuration information to obtain a Bluetooth MESH data packet, and forwards the Bluetooth MESH data packet in a Bluetooth MESH network. The forwarded Bluetooth MESH data packet is completely in Bluetooth MESH format, and a common SIG Model and a customized Vendor Model can be used. The target device relies on the perfect safety and reliability of the Bluetooth Mesh network, and can stably receive and respond to the corresponding actions. The target device may be a single device or multiple devices or logic groups, and the logic groups generally refer to nodes which are located at one position or need to be controlled together, such as all down lamps in a living room of a family, and are added into one logic group to be controlled together, so that all the down lamps in a corridor can be provided with one logic group, and the same lamp (node) can be located in multiple groups at the same time. Referring to fig. 1, a user controls a schematic diagram of a data path of a controlled device of a first logical group through a passive wireless switch.
In the invention, for a monitoring node, responses made after an adv packet broadcast by a passive wireless switch is received are different in different trigger modes, and in network access binding, the adv packet is monitored for finding and identifying a designated passive panel, and a characteristic value of the adv packet is stored in the monitoring node for subsequent user configuration; in the distribution control stage, the operation of corresponding translation, forwarding and the like is required to be carried out according to the stored configuration information when the adv packet is monitored.
If the configuration information stored in the monitoring node is default configuration information, default translation rules set by the equipment in factory, such as short-press switch lamp, long-press dimming and the like, are adopted. In practical applications, the configuration information may be modified, i.e. the translation rules may be customized. When a user needs to change the functions of keys or needs to select the number and range of controlled devices, such as configuring a key to control lights of a corridor and a key to control lights of a restaurant, the configuration needs to be changed.
Thus, the present invention also includes modifying the configuration: and reading the configuration information stored on the monitoring node through the Bluetooth MESH network for modification, transmitting the modified configuration information to the monitoring node and covering the configuration information before modification.
The configuration modification is the function of configuring the passive wireless switch, so that the configured information can be transmitted through the Bluetooth Mesh network, and the configuration process becomes very convenient. The configuration modification can be performed through the node, the node can select a mobile terminal with a display screen and Bluetooth functions, including but not limited to a mobile phone, a PAD, a computer, and application software (App) on various mobile devices with Bluetooth functions, and the App can read (using a Vendor model) configuration information stored on the monitoring node through a Bluetooth Mesh network. The mobile terminal can open a visual interface for a user to configure according to the capability of the passive wireless switch, and modified configuration contents include but are not limited to 1 and a response target range: single device, multi-device, logical group, broadcast, 2, response action: switch, dimming, scene, timing, etc.; 3. combining action responses: double click operation function selection, long press operation function selection, and the like. For example, when the user needs to configure the button No. 2 on the passive wireless switch to control the switching of the corridor lamp, the information 1 recorded in the corresponding configuration information, the adv and 2 corresponding to the button, the logical group 3 where the corridor lamp is located, the switching operation, 4, and no additional action.
After the user is set, the mobile terminal transmits the modified configuration information to the monitoring node through the Bluetooth Mesh network Vendor model, the monitoring node receives the modified configuration information and locally stores the modified configuration information, and the modified configuration information covers the configuration information before modification. And after receiving the adv packet broadcast by the corresponding passive wireless switch, the monitoring node translates the modified configuration information into a data packet of the Bluetooth Mesh and sends the data packet out through the Bluetooth Mesh network.
The invention also provides a passive wireless switch control system based on the Bluetooth MESH network, which comprises
