Wireless linkage sensing method, device and system

Technical Field

The invention relates to the technical field of wireless communication and edge intelligence of the Internet of things, mainly relates to a wireless cooperative sensing network and a mechanism and a process of edge cooperative sensing service of a cooperative sensing node for a target scene and a target object thereof, and particularly relates to a wireless linkage sensing method, device and system.

Background

For different intelligent application scenes, an Internet of things edge domain with dynamic information interaction characteristics, which is formed by edge service nodes of a perception control domain and peripheral target object equipment, is mainly used for solving the problems of wireless network communication and information interaction service mechanisms and processes of the target object domain and the perception control domain.

Considering the wireless coverage problem of the intelligent service of the scene of the internet of things, with the increase of the number of target object devices in the scene of the surrounding environment, if the perceived service capability of the edge domain for the target object devices with low power consumption is completely or excessively dependent on a dedicated service node or base station device (such as a host, a router, a gateway/relay, a positioning base station, etc.) of the internet of things, the wireless coverage and the computational power of the perceived service capability are insufficient or higher resource cost is consumed.

The problem to be solved by the target scene-oriented Internet of things edge intelligent technology is relevance decision and service based on scene perception. The target scene state is determined by a plurality of target objects associated with the target scene and associated state variables thereof, wherein most of the state variables are usually originated from low-power consumption wireless sensors or other perception monitoring devices serving as target object devices, the perception monitoring devices serve as target perception nodes and are also target object devices served by the edge perception network, and the association binding relationship is directly established with mobile objects or position environments of the served target scene.

The target sensing nodes have sensing and monitoring capabilities facing specific physical objects, but considering the problems of power consumption, resources, computing power, installation quantity or technical compatibility and the like, the target sensing nodes are not required to be multiplexed on the network service nodes generally, but when the power consumption resources allow for the necessity, the target sensing nodes can also fulfill partial responsibility of the role of the network service nodes so as to improve the multiplexing performance and the cost performance of hardware equipment of the edge network system.

Target object-target service object: refers to the objects (e.g., people, items, asset devices, locations, environments, etc.) being serviced (located, controlled, monitored, etc.). Target objects include direct or indirect service objects such as: locating a tracking object, tracking a monitoring object, monitoring a device object, energy monitoring an object (e.g., a power load object), etc.

The wireless cooperative sensing network (sensing network for short) is a wireless network formed by cooperative sensing nodes in the edge domain of the Internet of things; and providing cooperative sensing services such as object identification, positioning tracking, state monitoring, control monitoring and information pushing for peripheral target object-oriented equipment. And the plurality of cooperative sensing nodes acquire the target state information of the currently specified target scene object through cooperative sensing.

The target sensing node device is a target object device (referred to as an object device for short), and a sensing monitoring device (such as a passive positioning device, a wearable device, a distributed sensor, a monitoring and peripheral execution device, etc.) associated and bound with a target scene or a target object thereof.

The cooperative sensing refers to a process of sensing monitoring and associated services performed by a plurality of sensing nodes in a wireless network through cooperative sensing processing, wherein the sensing nodes face a common target scene or a subset (including a target object) thereof.

The target object device is a wireless device which is a service object of a peripheral wireless network node (base station device) and provides information interaction service; is a wireless device (such as an electronic tag, a sensor, an adapter, etc.) for performing association identification (or binding) on a target object.

The target scene object is a target object associated with a target scene; the target scene (scene for short) is a relation combination of a plurality of target objects and position environments thereof in a given physical space-time; the target scene may include several target scene subsets.

The perception monitoring device, namely the device with wireless perception monitoring capability, includes a target perception node (as a target object device or a scene sensor) directly facing a target scene object for perception monitoring, or a cooperative perception node facing a front perception node for perception monitoring.

The perception monitoring refers to the process of acquiring target associated information (such as signal receiving, data acquisition and processing and the like), and comprises the processes of identifying, tracking, monitoring and the like facing a target scene object.

The object identification means that information such as related equipment ID, service attribute, state variable and the like of a target object (equipment) is acquired through wireless scanning detection; the state monitoring means that the state variable range or the combination of the state variable range of the target object is analyzed and judged to obtain target state information associated with the target scene object.

The cooperative sensing node is a wireless network service node with cooperative sensing service capability, namely a wireless network node with the capability of providing the cooperative sensing service for peripheral target object equipment or target sensing nodes in the wireless cooperative sensing network. The cooperative sensing node is a node device role and can be a wireless base station device or a general sensing node; the sensing node is a network node capable of sensing and monitoring a target object.

The cooperative sensing service is a cooperative service provided for peripheral sensing nodes, and comprises wireless network communication and cooperative sensing processing facing sensing monitoring and correlation processes thereof.

The prior similar technology mainly has the following defects:

1. the problem of cooperativity: from the perspective of capability coordination, edge service node devices lack a complete wireless awareness capability model. Flexible cooperation service coordination is lacked among field network service nodes, and the cooperation service coordination comprises cooperation scene perception, wireless trigger response, cooperation data communication, node path selection, capability cooperation complementation and the like.

2. Edge calculation problem: from the physical level, the edge computing in the prior art, especially the data processing and intelligent decision undertaken by the edge domain intelligent hardware device, lacks the integral hierarchy and relies too much on individual core intelligent devices (the host, the intelligent gateway and the router of the internet of things), such as edge cloud computing, cloud edge collaborative computing, field network computing, intelligent terminal computing and target object computing.

3. Reusability problems of edge devices: from the perspective of equipment utilization efficiency, the edge service nodes are low in reusability, rely too much on dedicated intelligent equipment (a host of the internet of things, an intelligent gateway, a router and a positioning base station), and are less used for low-cost multiplexing nodes (such as monitoring and monitoring nodes like lamp controllers, sockets and switches) with wireless sensing computing capability.

4. Low power consumption object-oriented device problem: the existing edge wireless network communication technology mainly includes two types of wireless connection (point-to-point or point-to-multipoint) and Mesh network. Wireless interoperation towards low-power target object devices still lacks fast and efficient mechanisms. The wireless connection needs to exchange wireless communication parameters based on a handshake protocol in advance; when the Mesh network node responds to the peripheral low-power-consumption object device, the problems of quick scene trigger response and response mechanisms are not effectively solved.

Therefore, how to efficiently obtain a trigger response to a target scene state change when the wireless cooperative sensing node faces low-power consumption pre-trigger in the wireless cooperative sensing process so as to improve the reusability, flexibility and edge cooperative processing capability of the wireless cooperative sensing node becomes a technical problem to be solved urgently.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It is to be understood that the described embodiments are part, rather than all, of the present invention, and are intended to be illustrative of, and not limiting of, the present invention.

In a first embodiment, please refer to fig. 1, which is a flowchart of a wireless coordinated sensing method disclosed in an embodiment of the present invention, when a scene trigger response is obtained by a plurality of wireless coordinated sensing nodes (devices) in a wireless coordinated sensing network in an edge domain of an internet of things, a mode process corresponding to a target scene state is executed, the method includes the following steps:

step S101, when the cooperative sensing node receives wireless trigger state beacons sent by any multiple preposed sensing nodes in a target scene, the cooperative sensing node sends cooperative response information for triggering state smoothing/linkage response in a wireless linkage (multiple selection response mode) based on state hopping identification;

step S102, obtaining a scene state code (and jump information thereof) corresponding to the target scene through scene state analysis according to the target state information (and a plurality of target state variables Xi contained therein);

step S103, when the scene state code Ns undergoes state transition, obtaining a corresponding mode parameter through the index of the scene state code, and executing corresponding mode processing (and associated mode processing flow) according to the mode parameter.

The implementation of the above steps is further explained as follows:

the method comprises the steps that the trigger state beacon comprises a trigger state identifier, the receiving of the trigger state beacon and the extraction of the trigger state identifier are two alternate processes, and once the trigger state identifier is judged to be absent or no state jump information is indicated, the process for receiving the trigger state beacon is allowed to be stopped in advance.

The trigger state flag indicates that state transition information exists, which is a necessary condition for further performing scene state analysis, but may determine whether and in what manner to perform scene state analysis according to the time domain variation of the target state variable Xi.

The target state variable Xi is from the analysis of the present trigger state beacon, and may also include the target state variable Xi (t) (and a time domain change value) obtained in the earlier stage.

The cooperative response information is response information (sent when the cooperative sensing node obtains a pre-trigger response) used for triggering state smoothing and/or linkage response; optionally, the cooperative response information includes target multi-selection information, i.e., a group control multi-selection code and/or an enumeration code.

The preposed sensing node is used as a target sensing node, when a target object sensed and monitored by the preposed sensing node enters a critical triggering state, transient triggering response is obtained through critical feedback monitoring, and a triggering state beacon is sent.

In the critical feedback monitoring, the current cooperative sensing node or the preposed sensing node thereof performs feedback adjustment on the signal front end of the self node or the preposed sensing node according to monitoring acquisition information of a target state variable in a time domain (based on a current sensing monitoring mode) and based on judgment (including calculation or query) on the approach degree of transient trigger response so as to perform real-time comparison monitoring on the current front end input signal and obtain the transient trigger response when the preposed sensing node meets the preposed trigger condition.

The target sensing/monitoring node compares the front-end input signal with the current front-end comparison signal in real time based on a critical signal feedback unit (included in a signal front-end processing module) to obtain a transient trigger response when a pre-trigger condition is met.

The target scene state is called scene state for short, and is a certain physical state which is associated with the target scene and can reflect the specified target scene by a plurality of subsets or object states; for example, the scene state is a person (person/no person) in a specified area/room.

The object state information is information describing the state of the object scene/object and its changes.

The mode parameters are associated with scene states and include data information such as codes, indexes, processes, parameters and the like corresponding to a given mode.

The mode processing, i.e. mode data processing, includes data processing such as data calculation, operation/control/monitoring, data saving/transmission/uploading/pushing, and information service processes for a given mode.

The scene state code (referred to as scene code for short) refers to an identification code associated with a target scene and preset for reflecting scene state jump.

Obtaining a scene state code by performing scene state analysis on one or more target state variables; for example, the temperature and humidity (temperature/humidity combination zone code) in a region/room/location is specified.

If the target object belongs to the subset of the target scene, the cooperative sensing node performs scene state analysis facing the target scene based on the scene state analysis (obtaining the object state code and/or the local/subset scene state code) performed by the cooperative sensing node and/or the front sensing node.

The target sensing node/target monitoring node is a network node role, and directly senses and monitors a target object (with a built-in sensor).

The target sensing node is used as a target object device served by the cooperative sensing network and the cooperative sensing node thereof, and comprises a target positioning/tracking/monitoring node and a sensing monitoring device which establishes association or binding relation with a target object served by the target positioning/tracking/monitoring node.

The target state variable (state variable for short) is a physical state variable which is included in the target state information and is associated with the target scene object and reflects the target object and its associated environment.

The target state variables include direct variables or indirect indices associated with predetermined scenarios such as environmental states, target objects, event triggers, etc.

The target state variable is a physical quantity or an intermediate control state variable constituting a judgment target scene state and a change element thereof.

When a scene needs to be described by multiple target state variables, different state variables may be included in the same one or more state beacons, i.e., not all target state variables need to be included in the same state beacon.

The scene state analysis is oriented to a target scene/object and is completed by the cooperative sensing node itself or other cooperative sensing nodes through cooperative sensing processing.

When the target scene is composed of a plurality of target objects, the scene state analysis is completed based on the object state analysis.

The sensing node monitors and analyzes the variable values and the variable type information of one or more state monitoring variables through the class index of the state beacon sent by the target object equipment to obtain the state identification information of the target object.

The scene state analysis comprises the scene state analysis of a certain cooperative sensing node or a host higher than the cooperative sensing node by an overlapping or summarizing algorithm on the target scene based on the scene state information (as a local part or a subset) provided by a plurality of front-end sensing nodes.

The scene state information is obtained by a plurality of front sensing nodes through scene state analysis, and the method comprises one or a combination of the following modes: 1) performing cooperative sensing processing (such as cooperative positioning calculation) on the same target scene or object; 2) and respectively carrying out scene state analysis on a plurality of subsets or objects contained in the same target scene by different preposed sensing nodes.

The front sensing node refers to a front-level cooperative sensing node from which the cooperative sensing node receives a response currently wirelessly, and may be a front-most target sensing node or an intermediate sensing node.

The preposed sensing node refers to sensing monitoring equipment which obtains and sends a state variable to the current cooperative sensing node.

The preposed sensing nodes comprise target sensing nodes for acquiring target state variables Xi in a direct or indirect sensing mode or intermediate sensing nodes for receiving and processing data.

The front sensing node may have a multi-device role relative to the current cooperative sensing node, and may refer to a dynamic preceding-stage cooperative sensing node serving as a network service node, or may refer to a target monitoring node (a scene sensor or a target object device) serving as a periphery of a wireless network.

The target state variable Xi is from the analysis of the current trigger state beacon, and may also include a target state variable Xi (t) obtained in the earlier stage and a time domain change value.

In order to improve the efficiency of state transition identification of the prepositive sensing node (as an object device), object filtering and/or state filtering are carried out in the following modes before the state comparison:

1) object filtering: filtering according to the attribute (such as equipment name, address range and check code) of the object equipment, and skipping the non-target object equipment unconditionally;

2) and (3) state filtering: filtering according to the state of the object equipment, and preferentially processing the object equipment in the trigger state, and allowing unconditional skipping or non-preferential processing (such as skipping the object equipment at a lower activity level) for the object equipment in the non-trigger state.

In an actual implementation process, the object filtering and state filtering are composed of n filtering conditions, wherein an expression of any filtering condition is as follows: match code 1, [ match code 2, match code 3, ]; the matching code refers to a code (string) that matches an attribute and/or a state of the target device.

It should be noted that, 1) each filter condition at least contains one attribute condition, and a plurality of optional attribute conditions are in an and relationship; 2) when checking multiple attributes of a condition (allowing the checking order of multiple attributes to be set), the condition can be skipped using negative checking, i.e., any attribute or a subset thereof (e.g., high byte) does not match.

The result of the current cooperative sensing node performing scene state analysis is scene state information corresponding to the current target scene, and is reflected in the scene state code Ns.

The scene trigger condition comprises a condition of jump trigger and/or steady trigger of a target scene state; the above-mentioned scenario trigger condition can be regarded as a necessary and sufficient condition, if an additional condition (such as a space-time condition, an object condition, a parameter condition) is regarded as a condition for the scenario state analysis.

The target state variable is a physical quantity or an intermediate control state variable constituting a factor for determining a scene trigger condition, and is included in the target state information.

The jump trigger refers to the trigger generated by the change of the scene state code Ns;

the steady state trigger refers to a timing trigger generated by not generating a new transition trigger within a stabilization time (cooling time) effectively observed after the transition trigger.

When the target state variable exists in the state beacon sent by the preposed sensing node, the current cooperative sensing node can actively analyze the scene state to judge whether the scene state changes; and obtaining corresponding scene trigger response when the scene trigger condition is met.

When the target monitoring node is used as a preposed sensing node, the conditions of jump triggering and steady triggering and the embodiment thereof are as follows:

1) when the variable value meets the jump triggering condition, the target monitoring node is used for measuring the variables of the electric energy and the temperature sensor; motion and heart rate sensor variables of the smart bracelet (target monitoring node);

2) when the variable value meets the steady-state triggering condition, the motion sensor variable of the intelligent bracelet is overtime in a steady state (namely no static and dynamic triggering for a long time); the smart tag (object tracking device) continues to fail to receive a system response and times out (i.e., long no-response trigger).

The trigger status beacon is a status beacon containing specific trigger information.

The trigger information refers to information to indicate/remind a response to be received thereto.

The trigger belongs to a trigger reminding mechanism; even if the cooperative sensing node does not receive the trigger state beacon sent by the front sensing node, the scene state analysis can be performed based on any predetermined state or timing event trigger if necessary to judge whether scene state jump occurs.

A set of mode parameters Pi includes an index/call parameter to the mode process flow; executing a corresponding mode processing flow according to the operation mode parameters contained in the mode parameters;

the mode processing flow comprises scene linkage processing such as scene linkage control, scene linkage configuration and scene linkage communication. The mode processing flow comprises processing flows of data calculation and communication based on the cooperation of a local machine or multiple machines, such as mode adjustment, data configuration, linkage processing, data storage and uploading and the like.

And the cooperative sensing node obtains a mode parameter through a mode index according to a scene response plan associated with the scene trigger response and starts mode processing (such as monitoring data processing) associated with the mode parameter Pi.

For example, the data structure of the schema index is: [ INDEX ] scene status code- > mode code, priority, validity period; or: [ INDEX ] mode code- - > mode parameter, reference pointer.

The mode parameters comprise operation target parameters and/or operation mode parameters, and the adjustment of the mode parameters comprises adjustment operations such as parameter assignment, parameter increment, parameter function operation and the like.

The data structure of the scene trigger response can participate in the following embodiments:

1) sensor (unknown class): [ look up ] device name/device ID or MAC- - > device type code;

2) a sensor (known class), [ index ] device type code- - > scene status code, [ monitor variable 1.. monitor variable n ];

wherein, the sensor refers to the target sensing node.

Example two

The implementation of the foregoing steps of the flow chart of fig. 1 is further described as follows:

the cooperative sensing node receives the trigger state beacon sent by the preposed sensing node in a wireless (time slot synchronous) scanning detection mode, and performs linkage response when the linkage response condition is met: and as the wireless linkage node, transmitting a linkage trigger beacon for the cooperative response in a wireless beacon broadcasting mode.

The linkage response refers to secondary response obtained on the basis of scene trigger response obtained by the front sensing node.

The linkage trigger beacon can be used for triggering state smoothing as a cooperative response;

when the linkage trigger beacon received by the preposed sensing node meets the validity condition, the trigger state beacon is immediately closed or recovered to a non-trigger state (normal beacon).

The linkage trigger beacon replaces a native trigger state beacon to wirelessly trigger other cooperative sensing nodes in a preset number, so that the front-end sensor is enabled to be in a state recovery state (a normal beacon with low power consumption is recovered), the condition that the native trigger state beacon is insufficient in trigger space range is avoided, and redundant linkage signals are reduced (power consumption and cross interference caused by invalid trigger are avoided).

And when the linkage response condition is met, based on (effective) target state information contained in the trigger state beacon, the updated linkage identifier is placed in a new linkage trigger beacon and is used as a wireless linkage node to be transmitted in a wireless beacon broadcasting mode.

The linkage identification comprises a trigger response ID and a linkage level;

and the trigger response ID is the same as or equivalent to the trigger response ID contained in the linkage trigger beacon, and the linkage level is modified in a one-way (irreversible) way.

And the linkage trigger beacon is a new trigger state beacon formed by the cooperative sensing node through linkage information processing based on the trigger state beacon sent by the preposed sensing node received by the cooperative sensing node.

The coordinated trigger beacon is a non-primitive trigger state beacon (with respect to a particular scene state transition).

And after receiving the linkage trigger beacon sent by any preposed sensing node in the target scene, the cooperative sensing node sends cooperative response information for state smoothing/linkage triggering when the linkage response condition is met.

After receiving a trigger state beacon sent by any one preposed sensing node in a target scene, the cooperative sensing node immediately carries out trigger response: sending cooperative response information (including target multi-selection information, such as a group control multi-selection code and/or an enumeration code) for state smoothing (in a multi-selection response mode).

Based on the currently obtained target state variable (sent by one or more preposed sensing nodes), performing scene state analysis according to a scene state function and/or a scene data structure associated with the target scene (and/or the current preposed sensing node), obtaining the state information of the current target scene, and deriving the scene state code Ns.

When the target state information is wholly or partially originated from the current prepositive sensing node, the scene state analysis comprises the reference of a prepositive state code, and the prepositive state code is contained in the scene state code identification sent by the prepositive sensing node.

The cooperative sensing node (a front sensing node or a current sensing node) analyzes a scene state according to a scene state function based on the obtained (a plurality of) target state variables associated with the target scene, and derives the scene state code Ns corresponding to the target scene state.

The change in the target scene state is caused by a change contained in one or more target state variables;

the target state variable at least comes from a trigger state beacon which is sent by the front-end sensing node (in a direct or linkage wireless mode) and contains target state information.

The cooperative sensing node (in a time slot synchronous wireless scanning detection mode) receives target state information which is sent by one or more nearby preposed sensing nodes and contains a plurality of target state variables Xi;

one or more of the target state variables Xi are from target state information sent by a front-end aware node(s) (device (s)) associated with a target scenario.

And if and only when any prepositive sensing node in the current target scene sends the trigger state beacon containing state hopping information, the cooperative sensing node is taken as a necessary condition for currently starting the state analysis of the current scene.

And when the cooperative sensing node receives the jump of the trigger state identifier sent by any front sensing node, starting to analyze the scene state of the associated pointed target state variable Xi.

When the prepositive sensing node monitors at least one target state variable to jump, the prepositive sensing node sends a trigger state beacon by updating the corresponding trigger state identifier

The trigger state identification is an identifiable identification existing in a state beacon and corresponds to the state hopping information;

the trigger state identification may be included in the state code, i.e. the state code is used as the trigger state identification, or the trigger state identification is incorporated into the state code.

In an actual implementation process, the trigger state identifier is one or a combination of the following ways to indicate whether state transition information and a transition degree thereof exist: 1) distinguishing the state jump or not by specific values, 2) representing the state jump or not by whether the state code changes, and 3) representing the jump degree by different specific values.

The scene state resolution is to derive a scene state code based on scene state functions associated with a number of different scene trigger responses: ns ═ Fs (Xi) or Ns ═ Fs (Xi (t), (Δ Xi);

wherein Xi refers to a group of several target state variables Xi (t);

Δ Xi denotes the amount of change in the target state variable Xi over a given time.

The scene state resolution comprises: different scene class codes and/or scene trigger sources (target monitoring nodes and target state variables thereof) are provided with different scene validity periods and/or scene priorities (through presetting).

The scene validity period is the duration of the scene state obtained by the scene state analysis after the sensing node obtains the scene trigger response and before the new effective scene trigger response is not obtained.

The scene validity period identification is a dynamic identification which reflects whether the current scene state is in the validity period or not; (typically, the end of the validity period is set to 1 or 0 respectively for the scene validity period identifier) to obtain a new valid scene trigger response within the scene validity period, and the scene validity period is covered.

Scene priority rules: the scene priority is effective only in the scene validity period after the scene trigger response is obtained, and for the scene class code of the same target scene, a new effective scene trigger response can be obtained only when the new scene trigger has the same or higher scene priority relative to the original scene trigger in the scene validity period.

Multi-scene superposition rules: when scene trigger responses are obtained for a plurality of scene class codes of the same target scene within the overlapping time of the scene validity periods, the state variables of executed operations are operated according to logical OR; and the post-trigger scene is used for performing covering operation on the selected target.

The triggered state beacon is a state beacon (such as a wireless beacon and a carrier beacon) which is sent by the preposed sensing node and contains specific triggered state identification (a state code identification) information at an activity level higher than that of an un-triggered normal state by adjusting beacon broadcast/modulation parameters of the preposed sensing node, and is used for triggering the peripheral associated cooperative sensing nodes to receive and respond.

The beacon in the trigger state has the advantages of shortening the trigger response time (improving the trigger response speed) and reducing the probability of being interfered by the transient state, thereby improving the efficiency and the success rate of triggering the transient communication.

When the preposed sensing node or the cooperative sensing node is in a normal state (non-state triggering), the transmitted state beacon has beacon broadcast/modulation parameters with lower activity, so that the normal beacon broadcast power consumption is saved, and unnecessary air wireless cross interference is reduced.

And the cooperative sensing node (a front sensing node or a current sensing node) judges whether the scene state meets the scene triggering condition through scene state analysis to obtain a corresponding scene triggering response.

Namely, once the relevant sensing node judges that the scene state jump occurs, the scene trigger response can be obtained unless the scene trigger condition shields the scene trigger response.

And when the cooperative sensing node judges that the scene state of the current target scene jumps, the cooperative sensing node sends a scene state beacon (in a wireless beacon broadcasting mode) containing a scene state code identifier (as a trigger state identifier).

The scene state beacon is created by the current sensing node and can be used as an object state beacon received by the later-stage cooperative sensing node.

The scene state code identifier is used as a trigger state identifier and is identified by the next-stage cooperative sensing node and used for judging trigger and linkage response; the trigger state identifier is the same as or associated with the corresponding scene state code.

The prepositive sensing node adjusts the activity level of the status beacon thereof by setting the beacon broadcasting/modulating parameters:

in the (short) duration of the trigger state beacon, higher energy is allowed to be used as a cost, and the radio frequency signal capability of the state beacon is improved and/or a specific channel is given to occupy, so that the high transient communication success rate is achieved, and the quick trigger effect with higher sensitivity and reliability is obtained.

On the contrary, in a normal state (non-state triggering), the activity level is reduced by reducing or closing the radio frequency signal capability and/or specific channel occupation of the state beacon, so that the beacon broadcast power consumption and the wireless channel resource occupation are lower, and the air radio frequency cross interference is reduced.

The front sensing node (as a target object device for reverse control) receives active sending information of a certain cooperative sensing node, and the trigger state beacon is used as a response beacon and contains response information corresponding to the active sending information;

when the active sending information contains target multi-selection information (such as a multi-selection code), the preposed sensing node adjusts the time sequence and the activity level of the starting trigger state beacon according to the number of object nodes of the current target multi-selection information.

When the prepositive sensing node in the trigger state receives the cooperative response information, the sending of the beacon in the trigger state is immediately stopped or replaced by a normal beacon under the condition of meeting the validity.

The pre-sensing node enables reverse (synchronous) detection during the (short) period of sending the trigger state beacon, and immediately turns off or restores the trigger state beacon to a (non-trigger state) normal beacon when a cooperative response for state smoothing sent by an adjacent sensing node (meeting a validity condition, namely a preset number) is received in the reverse (synchronous) detection time slot.

If the preposed sensing node is a low-power consumption target sensing node, after the state flat-reply/cooperative response information sent by any cooperative sensing node is received in the synchronous detection time slot, the triggered state beacon is immediately closed or restored to the non-triggered state (with lower activity level) -the normal state beacon when the validity condition (such as a preset number) is met, so that the self power consumption is saved, and the transient radio frequency competition interference is reduced.

And when the state repetition/cooperative response information received by the sensing node contains the repetition correction for the current target state information, the sensing node judges the scene state jump based on the target state information after the repetition correction.

When the cooperative sensing node receives cooperative response information (with the same trigger state identifier) sent by a preset number of adjacent nodes, the cooperative sensing node closes the linkage trigger beacon sent this time; the cooperative sensing node can process the linkage trigger beacon sent by the adjacent node as cooperative response information.

The predetermined number is configuration information as a validity condition (within a limited time), associated with neighboring nodes or routing nodes, and included in the distribution network information, i.e., network topology information (as a kind of network topology information).

Obtaining scene state information (typically, a scene state code and associated information thereof) corresponding to a current target scene through a scene state function; and the scene state function establishes a data structure or a functional relation associated with scene triggering for one or a group of target state variables corresponding to the scene state information and the target scene.

And acquiring data structures corresponding to different scene state codes in the scene state function by pre-configuring and/or dynamically updating the mode.

Given one or more target state variables contained in the state beacon, a scene state code is derived for a given scene state function given target scene conditions (e.g., space-time domain conditions).

The scene state function comprises data relations in any one or combination of the following ways: 1) given the functional relationship: deriving the scene state code according to a given transformation function and/or an enumeration table through the target state variable; 2) the given value ranges are: that is, the scene state code is derived according to the value range (such as upper and lower limits) of the target state variable.

The object status beacon (status beacon for short) is a wireless beacon or carrier beacon which is sent by the target object device in an active broadcast and/or response feedback mode and reflects the characteristic attributes and the current physical status of the object device and the related objects thereof.

Typically, a connectable or non-connectable radio beacon or carrier beacon is included, which is transmitted both as a broadcast beacon and/or as a reply beacon.

And the cooperative sensing node receives a state beacon sent by peripheral target object equipment in a wireless broadcast manner through wireless scanning and detection.

The scene trigger response refers to the trigger response obtained by the current sensing node through the identification of scene state jump;

and the cooperative sensing node is used for determining whether the received scene state code Ns sent by the preposed sensing node jumps or not as a necessary condition for acquiring the scene trigger response and analyzing and processing the associated target state variable Xi.

The pre-aware node places the scene state code as a special state variable in its own state beacon.

For example, a scene state code sent by a certain front-end sensing node may be used as one of the target state variables on which the cooperative sensing node performs scene state analysis.

And if and only when the cooperative sensing node monitors that the scene state code Ns sent by the associated front sensing node changes, responding to a plurality of target state variables sent by the front sensing node.

The scene state jump refers to the jump meeting the preset change degree of the target scene by judging the designated associated target object and the target state variable or the combination thereof.

The degree of variation includes a given one or combination of: 1) a spatiotemporal range of a current target object; 2) the range interval of the current target state variable value; 3) rate of change of scene state and/or settling time.

And in the actual implementation process, the real-time jump or the stable jump is judged according to the combination of the change interval and/or the stable time of the target state variable. For example, the judgment that the target scene is a person or no person in the room: 1) when any sensing node (such as a human body sensor) detects a person in an unmanned state, the real-time jump (unmanned → occupied) of the scene state can be immediately judged; 2) in the presence state, if a certain sensing node does not detect a person and does not generate scene state jump, only if all sensing nodes in the target scene range do not detect the person within a period of stable time (cooling time and relaxation time), the stable jump of the scene state is formed (presence → no person).

The activity level refers to the ability of the sensing node to adjust the radio frequency signal of its status beacon and/or the occupancy of a particular dominant channel based on beacon broadcast/modulation parameters.

Beacon broadcast/modulation parameters include beacon broadcast interval, duration, power level, phase slot, frequency channel, and other modulation parameters.

In the existence period (a short time) of the triggered status beacon, the cooperative sensing node promotes the activity level through one or a combination of the following modes, so that the status beacon has a higher success rate of transient communication (thereby obtaining a quick triggering effect with higher sensitivity and reliability): 1) and (3) starting refreshing: starting beacon broadcast which is normally (non-triggered) stopped to operate or the type thereof (such as starting to send a broadcast packet and a response packet, and normally stopping sending or only sending one of the broadcast packet and the response packet); 2) and (3) accelerating the frequency: shortening the interval time of beacon broadcasting; 3) enhancing power: increasing the power level of the beacon broadcast; 4) specific channel: specific (protective, non-competitive) dominant channels are set, such as: phase slot channel, frequency channel.

The scene state beacon refers to a trigger state beacon which is sent by a current perception monitoring node in response to the state change of a specific target scene object and contains a scene state code.

The scene status beacon contains a trigger status beacon of scene status information, which may be, but is not necessarily, transmitted by a target monitoring node (sensor); for example, the scene status beacon is: 1) a status beacon transmitted by a target monitoring node (a scene sensor or a target object device); 2) the cooperative sensing node receives a plurality of trigger state beacons corresponding to the local target scene subset and transmits the trigger state beacons to the whole target scene (based on scene state analysis).

And the cooperative sensing node judges the linkage identification contained in the linkage trigger beacon, and if the linkage identification contains an effective and unresponsive linkage identification, the linkage identification accords with the linkage response condition.

The linkage identification is mark information reflecting the precedence relationship of the linkage forwarding of the related information.

In the actual implementation process, the following restrictive judgment is carried out on the linkage identification: 1) single use: each linkage relay node can only respond once (can last for a period of time) to a given linkage response ID to send a linkage trigger beacon; 2) unidirectional: unidirectional (irreversibility) based on linkage order; 3) and (3) limitation: judging N adjacent nodes: signal strength, number limit (typically 2-5); when the adjacent node sends the linkage signal, the transmission is stopped (interference is avoided).

The cooperative response information is response information which is sent by the cooperative sensing node when the cooperative sensing node obtains a pre-trigger response and is used for triggering state smoothing and/or linkage response; for example, the cooperative response message includes target multi-selection message, i.e., group control multi-selection code and/or enumeration code.

The validity condition of the cooperative response information includes any one or a combination of the following: 1) from an active wireless network node (e.g., a host or cooperative sensing node specifying an active class or attribute condition); 2) the cooperative response information contains a specific validity flag.

In the transient time after the preset sensing node performs linkage triggering (sends the triggering state beacon), once the cooperative response information meeting the validity condition (such as the valid nodes and the number of the valid nodes) is received in a reverse accumulation manner, the sending of the triggering state beacon is immediately stopped.

If the cooperative response message meeting the validity condition is not received within a limited transient time, the sending of the trigger state beacon may be stopped, typically in a slow-varying manner, and returned to a normal beacon.

The cooperative response information comprises target multi-selection information-multi-selection codes, and the preposed sensing section performs target matching verification on the target multi-selection information-multi-selection codes to judge and determine the validity of the state smoothing/cooperative response.

Typically, the target matching verification is performed by bit-selective comparison identification, which refers to a method for performing identification judgment on specific 'bits' in the multi-choice code, so as to judge whether the multi-choice code is matched.

When the front sensing node receives active control information sent by a certain cooperative sensing node, the trigger state beacon is used as a response beacon for performing response feedback on the active control information, and the response feedback is feedback on the receiving of the active control information and the execution state.

For example, in a process in which a cooperative sensing node (serving as a master device) controls a plurality of front-end sensing nodes (serving as slave devices), when the cooperative sensing node receives the trigger status beacon (serving as a response beacon), the target multi-selection information is updated (for example, the multi-selection code corresponding to the slave device is cleared through logic, for example, the corresponding enumeration code is deleted or the corresponding bit of the selection code is cleared), so as to represent status parallel/cooperative response information.

The cooperative sensing node is used as group control information sent by the group control master end equipment and comprises target multi-selection information so as to carry out group control and execution state monitoring on the plurality of wireless slave end equipment; and the triggering state beacon is used as a feedback mode of the group control execution state.

The adjacent nodes are cooperative sensing nodes adjacent to physical signals with mutual linkage response responsibility;

the method comprises the following steps that adjacent nodes judge the states of the adjacent nodes by receiving observation state beacons or trigger state beacons: whether all or selected neighboring nodes have obtained the necessary trigger response to the current trigger state identification.

The adjacent nodes reflect the mutual topological structure relationship among the cooperative sensing nodes in the wireless cooperative sensing network, and are automatically configured through automatic mutual discovery identification (the number of the adjacent nodes and the signal strength) and request response in the initial networking or updating configuration process of the wireless network.

The target state information includes one or a combination of the following information associated with the target scene and/or the target object: environment monitoring information, active positioning information, linkage alarm information and advertisement service information;

the active positioning information is used for being sent to target terminal equipment for calibration or correction of active positioning calculation, and comprises one or a combination of the following information:

positioning base station position, transmitting channel and modulation parameter, AOT positioning parameter (such as antenna signal transmitting direction/angle), RSSI positioning parameter (such as signal power level, correction amount).

1) Calculating the absolute or relative rate of change of the variable Xi according to the linear sensitivity deviation evaluation:

Those skilled in the art will appreciate that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above.

The embodiment of the invention also discloses a wireless linkage sensing system which is established by utilizing the wireless linkage sensing method in the first aspect;

the system is composed of a plurality of sensing nodes in a wireless cooperative sensing network in an edge domain of the Internet of things, wherein the sensing nodes comprise cooperative sensing nodes serving as network service nodes and target sensing nodes serving as front sensing nodes (namely sensing monitoring nodes facing a target object, such as a scene sensor or target object equipment).

The system is established by a wireless management node (such as a mobile phone, a computer, a gateway) by initiating a multi-mode wireless distribution network, wherein the multi-mode wireless distribution network comprises: the cooperative sensing nodes support a multi-mode wireless communication protocol, receive distribution network information which is sent by the management node in a synchronous data packet (namely a synchronous group control mode) and comprises an SSID (service set identifier) in a wireless scanning detection mode (such as Bluetooth BLE and wireless time slot synchronization), establish wireless connection with one or more appointed wireless routing nodes in another wireless communication protocol standard (such as WiFi) based on the distribution network information, and construct a Mesh communication-based network system.

The multi-mode wireless distribution network has the advantages that the efficiency of the group control distribution network (quick networking) is greatly improved: the distribution network management node enables a plurality of-numerous edge nodes/sensing nodes of a to-be-distributed network to be rapidly accessed to one or more designated wireless routing nodes (to construct a Mesh communication-based wireless cooperative sensing network) according to the distribution network information contained in the synchronous data packet and the designated network topology information, which are received at the same time, in a synchronous group control mode.

When the cooperative sensing node receives a trigger state beacon sent by the prepositive sensing node, the state jump identification is carried out according to a state code contained in the trigger state beacon: and comparing the current state code with the state code stored in the last processing to judge whether the state jump information which is not processed before exists.

The distribution network object device is inquired about a state record (such as a state code, a time interval, a main state variable and the like) stored in recent exception handling in an order code index mode by identifying a distribution network code and a distribution network order code of the distribution network object device.

The distribution network management node synchronously acquires state beacons of peripheral nodes in a wireless time slot, and finds a plurality of edge nodes/sensing nodes meeting matched attribute conditions; the edge node/sensing node refers to a distribution network or a wireless slave end device to be connected (a wireless device at the edge/periphery of the connectable communication).

The sensing node selects wireless protocol modes (such as Bluetooth BLE and WiFi) and mode parameters related to wireless topology (such as wireless connection and/or Mesh communication) and data transmission based on linkage trigger response.

The distribution network management node is a master end device for leading distribution network information and a distribution network process; the distribution network management node (as a device role) may be an agent node, a routing node (gateway), an upper host, or a mobile management terminal equipped with an APP.

The distribution network management node sends the distribution network information to edge nodes/perception nodes of a plurality of designated target equipment groups in a wireless time slot synchronization mode through wireless directional broadcasting-synchronous sequence beacons, and synchronous data packets containing target multi-selection information (such as multi-selection codes) are sent.

The distribution network information comprises parameter information (such as matching attribute, routing topology, security check and connection parameters) for distribution network and/or wireless connection; the wireless distribution network information comprises SSID and other associated parameter information.

The edge node receives the synchronous data packet in a wireless time slot synchronous mode, and starts a Mesh linkage node by identifying the group control code; and establishing wireless matching connection with the appointed wireless routing node according to the distribution network information (according to the SSID information).

In the actual implementation process, the edge node obtains the wireless distribution network information through wireless scanning and detection in a bluetooth wireless mode, and then establishes wireless matching connection with a specified wireless routing node (wireless router) in a WiFi wireless mode.

Judging whether the unprocessed state jump information exists or not by comparing the states of the preposed sensing nodes, wherein the method comprises one or a combination of the following methods:

1) index comparison: if the preposed sensing node is a distribution network object device, state comparison is obtained through indexing of a distribution network sequence code of the preposed sensing node;

2) searching and comparing: if the preposed sensing node is a common object device, the state comparison is obtained by searching the ID (such as the MACD address) of the object device in the current object hot list; and if the search fails, adding the preposed sensing node into the object hot list.

It should be noted that when the object hot list exceeds the amount or buffer limit, the escape processing is performed in a first-in first-out (possibly in combination with priority), and the object device currently in the trigger state has higher priority to remain in the object hot list for a longer time.

And eliminating the object equipment with low priority and long retention time by limiting the quantity or buffer of the object hot list so as to ensure that the running speed of the searching and comparing algorithm meets the specified requirement.

Before the preposed sensing node starts to send the beacon in the trigger state, if the channel detection is busy, the preposed sensing node allows the avoidance condition to be relaxed and sends the beacon in a priority mode compared with the non-trigger state (normal beacon); the preference means includes any one or a combination of: 1) more allowed transmission channels; 2) wider transmit slot limits; 3) a shorter transmit slot interval; 4) allowing the transmit power level to be raised if necessary.

In the practical implementation process, before the front-end sensing node starts to send the status beacon, the signal intensity of the air wireless channel is detected by channel detection and avoidance, and a necessary avoidance mechanism comprises: if the channel detection result is idle, the state beacon can be sent immediately; otherwise, if the channel detection is busy, the channel detection is tried after the time delay backoff or the channel change; if the status beacon cannot be successfully transmitted within a specified transmission time slot limit (time or number limit), a transmission failure record is sent; and transmits in the next active transmit slot.

After the preposed sensing node starts to send the trigger state beacon, the activity level of the state beacon is processed according to one or the combination of the following modes: 1) after a short trigger condition, decreasing the beacon activity in a specified manner (e.g., timed fade); 2) reverting to normal beacons (typically ultra low power states) after a specified response time limit is reached or exceeded; 3) the normal beacon may be restored upon receipt of the cooperative response.

Further, the non-trigger state (normal state) can be divided into an intermediate state, a normal state and a closed state according to the activity of the state beacon; the activity level is associated with a state period, which is automatically adjusted down after obtaining a coordinated response or gradual cooling.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. These should also be construed as the scope of the present invention, and they should not be construed as affecting the effectiveness of the practice of the present invention or the applicability of the patent.
