Fig. 1 is a schematic diagram illustrating the steps of an embodiment of the positioning system based on a topology network according to the present invention. Referring to fig. 1, the positioning method based on the topology network of the present invention includes the following steps:

step S10, a plurality of intelligent devices are provided in a predetermined space, and each of the intelligent devices has a communication module and a detection module.

The preset space is a three-dimensional space, and includes but is not limited to a home environment space, an office environment space or any one three-dimensional space set by a user; the smart devices include, but are not limited to, various home devices, office devices, or various smart devices serving users.

The detection module is used for detecting the interaction state of the intelligent equipment and a user and generating an instruction signal according to the state. The detection module includes, but is not limited to, a sensor module such as a pressure sensor, a gravity sensor, or an infrared sensor, etc. The communication module can broadcast the information of the intelligent device. The communication module includes but is not limited to a bluetooth module and the like. The broadcasted content at least comprises the name of the intelligent equipment and trigger information. The triggering information at least includes whether the smart device is triggered, for example, whether the smart device is activated, used, touched, and the like.

And step S11, the communication module is used as a node to carry out distribution network, and a topological network with a positioning function is formed.

The topology network includes, but is not limited to, a star-structured network, a ring-structured network, a bus-structured network, a distributed-structured network, a tree-structured network, a mesh-structured network, a cellular-structured network, and the like.

The communication module is used for carrying out distribution network through one of UWB, IBEACON and BLE MESH networks. Taking the communication module as a bluetooth module, the topology network as a MESH network, and the communication module performing a network distribution via a BLE MESH network as an example, a process of forming a MESH network with a positioning function will be described: when the communication module is distributed through a BLE MESH network, firstly, the Bluetooth module serves as a Bluetooth node to be distributed through the BLE MESH network, and the Bluetooth node performs positioning guidance on intelligent equipment in a coverage area of the Bluetooth node; secondly, the Bluetooth nodes distributed through the BLE MESH network cover the positioning guidance of the intelligent equipment in the whole network area through broadcasting relay, so that a three-dimensional MESH structure network with a positioning function is formed.

Step S12, the user triggers the smart device, and the detection module corresponding to the smart device generates an instruction signal. The purpose of this step is to determine whether there is a person in the vicinity of the smart device by whether the detection module generates a command signal. When the detection module can generate an instruction signal, the fact that people are nearby the intelligent device is indicated, and when the detection module does not generate instruction information, the fact that people are nearby the intelligent device is indicated.

In this step, the user triggering the smart device means that the user approaches the smart device or contacts the smart device, so that the detection module generates an instruction signal. When the user approaches the intelligent device, the detection module detects the user, and then the detection module generates an instruction signal, for example, the intelligent device is a reading lamp, and when the user approaches the reading lamp, the detection module of the reading lamp senses the user, and then the detection module generates an instruction signal. The contact includes, but is not limited to, pressing, touching, pushing and pulling, and when a user contacts the smart device, the detection module detects the user, and then the detection module generates a command signal, for example, the smart device is a sofa, and when the user sits on the sofa, the detection module of the sofa senses the user, and then the detection module generates a command signal.

The utility model also provides a system for according to foretell positioning system founds the scene. The utility model discloses the method of founding the scene can provide suitable scene according to the change of user's position, and the flexibility ratio is high, highly agrees with the user demand.

Fig. 2 is a schematic diagram of steps of an embodiment of the system for constructing a scene. Referring to fig. 2, the system for constructing a scene according to the present invention includes the following steps:

steps S20 to S23 are the same as steps S10 to S13, and are not described again. In step S23, the current real-time location of the user is determined according to the broadcast of the intelligent device that sent the broadcast last time in the topological network, that is, the user may trigger multiple intelligent devices within a certain time period, and the multiple intelligent devices in the topological network all send broadcasts, and the broadcast of the intelligent device that sent the broadcast last time is used as a basis for locating the current location of the user. For example, the user triggers the intelligent device 1, the intelligent device 2, and the intelligent device 3 in sequence, all of the three send out broadcasts, and the broadcast of the intelligent device 3 that sent out the broadcast last time is used as a basis for determining the current real-time position of the user.

Step S24, the communication module of at least the relevant intelligent device obtains the broadcast, generates the broadcast of the intelligent device, and shares the broadcast in the topology network, where the content of the broadcast at least includes the name of the intelligent device.

The related intelligent equipment is the intelligent equipment which is in the same scene with the intelligent equipment triggered by the user in a preset rule. For example, if the scene is a living room reading scene, the sofa and the reading lamp in the living room in the smart device are related smart devices, and the reading lamp in the study room is not related to the sofa in the study room.

In this step, the communication modules of all the smart devices may acquire the broadcast, or only the communication module of the smart device associated with the smart device that sent the broadcast may acquire the broadcast. The communication modules of other intelligent devices can obtain the broadcast by subscribing the broadcast sent by the communication module of the intelligent device triggered by the user, and if the communication modules of other intelligent devices do not subscribe the broadcast, the communication modules of other intelligent devices cannot obtain the broadcast.

Further, in this step, at least the communication module of the relevant smart device filters the broadcast by identifying a device name or a device MAC address, and acquires the filtered broadcast. That is, the related intelligent device may determine whether the intelligent device is related by identifying the device name or the device MAC address of the intelligent device that sent the broadcast, and if so, it acquires the broadcast, and if not, does not acquire the broadcast.

After the broadcast is obtained, if the intelligent equipment is related to the intelligent equipment sending the broadcast, the broadcast of the intelligent equipment is generated and shared in the topological network to be used as a reference for judging the relationship between the two related intelligent equipment by the system

And step S25, opening and/or closing the corresponding intelligent equipment according to a preset rule, and constructing a scene.

The preset rule may be preset in the mobile terminal. In this embodiment, the preset rule includes an association between the smart devices and a relationship definition between the smart devices. Namely, the preset rules relate to relevant intelligent device interaction scenes and interaction rules.

The association between the smart devices may be set as: the intelligent devices in the same scene are related intelligent devices. For example, if the scene is a kitchen cooking, the smart device (such as a range hood, a lighting system, etc.) serving the kitchen cooking is a related smart device; if the scene is reading in the living room, the intelligent devices (such as sofas and reading lamps in the living room) serving for reading are related intelligent devices.

The relationship definition between the intelligent devices can be set as: whether the related intelligent devices are within a set threshold value range. Wherein the set threshold range includes, but is not limited to, the set distance threshold range. For example, if the scene is a living room reading scene, a set distance threshold range is provided between the sofa and the reading lamp serving the living room reading scene to form the living room reading scene.

Further, in step S25, if the smart devices are related smart devices and the smart devices are within a set threshold range, controlling the smart devices to be turned on or off to construct a scene; and if the intelligent devices are related and are out of the set threshold range, canceling the control of the intelligent devices. For example, if the scene is a living room reading scene, a sofa and a reading lamp serving the living room reading scene are related intelligent devices, and if the relative position relationship between the sofa and the reading lamp is within a set distance threshold range, the reading lamp is turned on to form the living room reading scene; if the sofa or the reading lamp is moved, the relative position relationship between the sofa and the reading lamp is not within the range of the set distance threshold value, namely the sofa and the reading lamp are far away from each other, and the reading lamp cannot provide enough illumination for reading even if the reading lamp is turned on, so that the reading lamp is not turned on.

The utility model discloses the method of founding the scene is based on the broadcast information of smart machine in the topology network, can judge the position that the user is located and predict user's action, and then carries out the scene according to user and smart machine's interactive state and founds, accords with the user demand, and the flexibility is high, can promote user experience greatly.

A system for performing a scene construction system based on a BLE MESH network is illustrated below.

(1) The Bluetooth module arranged in the intelligent equipment is used as a BLE node, and a network is distributed through a BLE MESH to form a MESH structure network with a positioning function. In this step, the dots are arranged according to the specific indoor conditions, and a grid-like distribution is formed in the three-dimensional space. .

Specifically, each Bluetooth module performs positioning guidance on intelligent equipment in an overlay grid area through BLE MESH networking; through the bluetooth module behind BLE MESH network group net, accessible broadcast relay to cover the location direction of smart machine in whole network zone of MESH structure, form the MESH structure network that has locate function. The mesh network may be used to determine the distance and relevance of the smart devices to each other.

(2) The intelligent device performs Bluetooth broadcasting.

Specifically speaking, all be equipped with corresponding sensor module on each smart machine, through judging whether corresponding instruction takes place for the sensor module that corresponds on each smart machine to judge whether someone is near this smart machine. If the corresponding sensor module on the intelligent equipment generates an instruction, which indicates that people exist nearby the intelligent equipment, the intelligent equipment processor controls the corresponding Bluetooth module to perform Bluetooth broadcasting; if no instruction is generated on the corresponding sensor module on the intelligent equipment, it is indicated that no person is near the intelligent equipment, and the intelligent equipment does not generate a corresponding operation instruction.

(3) The locations of other intelligent devices in the mesh network are determined.

The Bluetooth modules of other intelligent devices acquire the broadcast information of the intelligent devices related to the other intelligent devices through screening the broadcast information, generate corresponding broadcasts for the intelligent devices in respective ranges, and share the broadcasts of the intelligent devices in the whole mesh structure network through broadcast relays.

(4) And each intelligent device performs corresponding operation according to a preset rule.

Specifically, the system confirms the current real-time position of a person according to the broadcast of the intelligent device which sends out the Bluetooth broadcast information for the last time in the network area of the mesh structure; the system acquires the broadcast of other intelligent devices, and judges whether the related intelligent devices are located in a specific threshold range according to preset association among the intelligent devices; if the related intelligent devices are located in a specific threshold range and have relevance, constructing a corresponding scene; and if the relative intelligent devices are beyond the range of a specific threshold value, the control of the intelligent devices is cancelled.

An embodiment of a system for building a scene is listed below.

The sofa is a comfortable and small cloth sofa which can be moved at will. The household lighting system comprises various lamps in a household, such as a room ceiling lamp, a living room ceiling lamp, a bedside lamp, a floor lamp and the like. The illuminance sensor is a common sensor in the market, and can distinguish the illuminance of natural light and artificial light.

The sofa, the lighting fixtures and the illuminance sensor are connected to a BLE MESH network as intelligent equipment. The BLE MESH network has a positioning function and can accurately position the relative spatial position and distance of each intelligent device.

The system sets the scene that a user needs 600Lux illumination when sitting on a sofa.

When a user sits on the sofa, the built-in pressure/gravity/infrared sensor detects the user and broadcasts the user to the outside through the BLE MESH network. Broadcast content includes, but is not limited to: "item name, user action".

The content of the broadcast is received by the luminaires of the home lighting system. Each lamp of the household lighting system obtains the position of the sofa through the BLE MESH network, and also indirectly obtains the position of the user.

For example, a person reading a book in a bedroom, a floor lamp may provide illumination; people should be illuminated by the ceiling lamp of the living room in the living room, and the floor lamp of the bedroom can cause the waste of electric energy when working again. Floor lamp, ceiling lamp, furred ceiling lamp etc. obtain people's positional information through BLE MESH system to it should work to have decided which lamps and lanterns, and which lamps and lanterns can not work. Suppose that at this time a person is reading in the living room, which is illuminated by a ceiling light.

The illumination sensor on the sofa can distinguish natural light from artificial light. Knowing the illuminance of natural light, the illuminance to be provided by artificial light (lamp) is known. Wherein, 600 lux-natural light is artificial light.

The illumination values of different distances from the lamp can be known through the basic parameters of the lamp, and the distance between the lamp and a person can be obtained through a BLE MESH network system. The lamp can calculate the duty ratio required to work, so that the position of the person reaches the required illumination value. And the illuminometer can be used as system feedback, so that the system can be dynamically adjusted according to the change of ambient light, and the stability of 600lux is ensured. If the lamp is adjusted to maximum, the illumination is still not achieved. The system may then alert the user to take eye care, provide ambient illumination near the light fixture or other measures.
