Description

Wireless low-power consumption configuration method and device

Technical Field

The invention belongs to the technical field of wireless communication of an edge domain of an Internet of things, and particularly relates to a wireless communication mode, a service mechanism and a process between a network service node and low-power consumption target object equipment (and a group thereof), in particular to a wireless low-power consumption configuration method and a wireless low-power consumption configuration device.

Background

For different intelligent application scenes, an Internet of things edge domain with dynamic information interaction characteristics, which is formed by an Internet of things edge service node and a plurality of target object devices (namely network client devices) around the Internet of things edge service node, is mainly used for solving the service mechanism and flow problems of wireless network communication of the target object domain and a perception control domain and information interaction of the wireless network communication.

The target object devices facing the internet of things edge domain network and the service nodes thereof not only comprise strong intelligent terminal devices which support standard wireless network access like computers and intelligent mobile phones, have strong resource capacity and can install various application software, but also comprise mobile or distributed target object devices (such as wearable devices, distributed sensors, peripheral execution devices and the like) with lower cost, ultra-low power consumption and relatively weak resource capacity.

In addition to the interoperability problem of dynamic access network, when a network service node needs to perform concurrent service on a target object device serving as a client in a 'one-to-many' or 'many-to-many', a balance among hardware resources, power consumption and transient response efficiency needs to be pursued, that is, one or more service node devices can simultaneously provide services of synchronous transient triggering and concurrent data transmission for a plurality of target object devices or device groups in a low-power standby state.

And a plurality of cooperative agent nodes with the same or interrelated equipment network attributes in the edge domain of the Internet of things and a plurality of peripheral agent nodes form a cooperative agent network system through a cooperative distribution network. The cooperative agent nodes are managed by an upper cooperative agent node or a network system host (simply referred to as a system host); the service node equipment can perform wireless scanning detection on wireless beacons sent by the target object equipment in different channels or time slots, and can monitor and collect state variable feedback of the peripheral numerous target object equipment in one moment (in extremely short time); typically, wireless devices are able to acquire wireless beacons in a wireless scanning probe fashion up to tens to hundreds of times per second. However, since the wireless scanning probe needs to occupy more power consumption and resources, the target device in a low power standby state before the wireless connection is established cannot obtain the fast trigger response and the concurrency control from the service node device in the same manner.

In the prior art, although the wireless directional broadcasting has simple topological structure, less occupation of wireless resources, high synchronous data transmission efficiency, fast triggering response speed, simple wireless protocol and good interoperability, the wireless directional broadcasting has obvious defects: the data transmission direction is asymmetric, the asynchronous data transmission efficiency is low, the data receiving feedback monitoring efficiency is low, and the power consumption of the wireless receiving end is high.

Although the wireless multipoint connection can perform multipoint bidirectional wireless data transmission, the wireless data transmission is stable, the asynchronous connection communication is convenient and the safety is relatively high, the wireless multipoint connection has certain defects, such as: the response time for establishing the connection is longer, and the wireless multi-point connection tends to be poor in stability, short in wireless transmission distance and high in wireless transmission power consumption, particularly when the number of client devices is large, due to the fact that the wireless channel resources are occupied greatly, and the environment and the resource factors are also dependent.

Although the wireless Mesh network is simple in installation and configuration, easy to quickly networking, flexible in wireless transmission path, strong in redundancy mechanism and communication load balance and low in wireless transmission power, the wireless Mesh network also has obvious defects such as: the wireless interoperability is poor in compatibility, the wireless communication delay is high, the cross coverage of different wireless standards is poor in cooperativity, and the problem of balance between standby power consumption and trigger response time is solved especially when the low-power consumption client equipment is not suitable for being used as a relay node.

In summary, how to solve the group control trigger response to the low power standby wireless receiving device, how to solve the balance between the wireless mode parameter and the receiving power consumption of the wireless receiving device, how to avoid the standby power consumption of the wireless receiving device in the non-data receiving state most of the time, and how to solve the balance between the wireless configuration data receiving and the standby power consumption, becomes a technical problem to be solved.

Referring to fig. 1, a flowchart of a wireless low power consumption configuration method disclosed in an embodiment of the present invention is described in detail as follows:

in step S101, before the wireless master device sends a group configuration synchronization packet to the plurality of wireless slave devices in the low power standby state, the wireless master device sends a wireless directional call broadcast including a synchronization modulation identifier and a synchronization time identifier in a specific wireless mode.

In the implementation process, the wireless master device or the wireless slave device is a relative role between devices: when wireless data communication is performed between two wireless devices, one of the two wireless devices, which is dominant to the wireless data communication mode and process, is a wireless master device, the other wireless slave device is typically a wireless master device, that is, a service node device, and the wireless slave device is typically a target object device in the network system, in this embodiment, the wireless master device is a synchronous modulation initiating device, and the wireless slave device is a synchronous modulation executing device.

The wireless master device performs wireless mode management including planning, reservation and switching on the wireless slave device through adjustment of wireless mode parameters.

The wireless directional broadcasting is a wireless broadcasting signal sent by a wireless sending device to a specific network domain, a specific target object device (wireless receiving device) or a target device group, typically, a beacon sending time slot of the wireless directional broadcasting is kept in time domain matching with a detection receiving time slot of the specific target object device, and typically, when the wireless sending device performs wireless directional broadcasting, wireless beacons which are reversely sent in different wireless channels or time slots from a plurality of wireless receiving devices are monitored and collected through wireless scanning detection at the same time, so as to realize a wireless directional broadcasting mode, for example:

1) Transmitting a wireless broadcast signal through a wireless modulation channel and a time slot of a specific physical layer;

2) The wireless broadcast information is transmitted through a specific algorithm or limiting parameter information.

The synchronization modulation identifier is identification information of wireless synchronization receiving modulation for the wireless master device to instruct the wireless slave device which maintains a synchronization matching state with the wireless master device.

The synchronization time identifier is identification information which exists in the wireless beacon and reflects the relative time characteristics of the wireless beacon transmitted by the wireless device in the synchronization time period.

The synchronization time identification contains one or a combination of the following relative time characteristics:

1) Synchronization indication identification: marking a specific time sequence position in the synchronous time period Ts without directly giving characteristic parameters;

2) Synchronization offset identification: indicating the relative time offset from a particular timing position within the synchronization time period.

At least one of the sync sequence beacons has a sync offset identification during one or more sync time periods;

the synchronization offset is identified as a relative time offset to a particular timing position within a corresponding synchronization time period that reflects the time of the transmit and receive back edge of the synchronization beacon in which it is located.

Further, the wireless beacon is a wireless signal which is sent by the wireless device in an intermittent and periodic manner through wireless broadcasting or response mode, contains set wireless device attributes and other application short messages, and can be obtained through wireless detection by the surrounding similar wireless devices.

Further, based on the given synchronization time period parameter, the actual dynamic synchronization time period is a fixed value or an adjusted value subjected to pseudo-random disturbance:

Ts'＝Ts*(1+Δ)

where Δ is a pseudorandom scrambling code much smaller than 1.

The synchronization time slot modulation is a wireless synchronization reception modulation performed by the wireless slave device on the synchronization detection reception time slot related mode parameter, and the wireless slave device performs a wireless reception modulation on the device itself according to a synchronization instruction of the wireless master device which maintains a synchronization matching state with the wireless slave device.

The wireless synchronous receiving modulation refers to wireless receiving modulation performed by the wireless slave terminal equipment in a synchronous matching state, and the wireless slave terminal equipment dynamically adjusts the transmitting/receiving state and related mode parameters of the equipment according to a given time sequence based on the current modulation characteristic parameters according to the synchronous instruction of the wireless master terminal equipment which keeps the synchronous matching state.

Further, the wireless reception modulation includes: in the wireless detection and data receiving process of the wireless receiving equipment, the wireless receiving equipment detects and receives wireless signals from the wireless transmitting equipment based on the current modulation characteristic parameters, and dynamically adjusts the associated mode parameters and radio frequency parameters according to a given time sequence; the wireless receiving modulation comprises wireless receiving time slot modulation and/or wireless receiving coupling modulation, wherein the wireless receiving time slot modulation is used for dynamically adjusting the wireless signal detection receiving time slot and the time sequence parameter thereof by the wireless equipment; the wireless receiving coupling modulation is that the wireless equipment dynamically adjusts the radio frequency receiving parameters of the wireless signal receiving coupling performance.

In the embodiment of the invention, the synchronous time slot modulation is associated with a modulation characteristic parameter, namely a synchronous detection time slot parameter (the synchronous detection time slot parameter is included in the wireless mode parameter), and the synchronous time slot modulation comprises one or more groups of parameters including synchronous detection time slot width, synchronous detection time slot period, synchronous detection time slot phase and synchronous detection time slot duty cycle, wherein the synchronous detection time slot duty cycle is synchronous detection time slot width/synchronous detection time slot period.

In the embodiment of the invention, the modulation characteristic parameter associated with synchronous time slot modulation is given by any one or combination of the following modes:

1) Preconfigured modulation information: the method comprises the steps of pre-configuring modulation characteristic parameters and modulation scheme information;

2) Indication of synchronous modulation identity: included in the synchronous sequence beacon sent by the wireless master device;

3) Based on state feedback modulation: and carrying out feedback modulation according to the state monitoring variables of the equipment and the service object thereof.

And the wireless slave terminal equipment carries out self-adaptive time slot modulation on the modulation characteristic parameters associated with the wireless time slot synchronization according to the state requirement of the current synchronous data transmission.

The wireless slave terminal equipment selectively receives and modulates the requirements of different data sub-packets (namely synchronous data packets with different sub-packet sequence codes) in a series of synchronous data packets according to the self-demand, and carries out synchronous time slot modulation based on multi-time slot synchronous matching; the multi-time slot synchronous matching refers to that the wireless slave terminal equipment dynamically sets a plurality of synchronous receiving time slots according to the matching relation with the detection phase time of a plurality of data sub-packets in one or a plurality of synchronous time periods.

The receiving modulation requirement is given by a receiving modulation multi-selection code, wherein the receiving modulation multi-selection code is a multi-selection code (such as a bit selection code) for performing multi-selection on different data packets in a series of synchronous data packets;

the received modulation code is given by any one or combination of the following: 1) Predetermined default values: selecting all data sub-packets (according to the total number of the series of synchronous data packets); 2) Given an initial value: the synchronous group control code and/or the synchronous modulation identifier are/is contained in the synchronous group control code and/or the synchronous modulation identifier which are/is transmitted by the wireless master terminal equipment and received by the wireless slave terminal equipment; 3) Modifying the dynamic value: after each synchronous data packet is received by the wireless slave terminal equipment, the selection of the synchronous data packet is shielded according to the corresponding packet sequence code, and the multi-packet verification identification (the state verification code of the data packet reception) is updated.

When the wireless slave terminal equipment receives a series of synchronous data packets, synchronous detection is not required to be started in synchronous transmission time slots corresponding to unselected or successfully received data packets, so that the self synchronous detection time slot power consumption is greatly reduced.

On the premise that the wireless slave terminal equipment and the wireless master terminal equipment keep a synchronous matching state and the synchronous time parameter is not changed, the wireless slave terminal equipment automatically carries out synchronous time slot modulation on the equipment according to the current modulation requirement and the self-adaptive multiplying power modulation mode, wherein the self-adaptive time slot modulation comprises: a synchronous detection slot width modulation and a synchronous detection slot period modulation.

Typically, a modulation mode of integer multiplying power N is adopted for time slot frequency modulation (that is, the mutual integer multiplying power between synchronous frequencies corresponding to a synchronous time period Ts is maintained), so that a synchronous matching state is maintained with the wireless master device;

synchronous detection slot cycle modulation (example):

enhancement (acceleration): tr=tr/N or Ts/N,

slow (slow): tr=tr x N or Ts x N,

tr and Ts are respectively the current synchronous detection time slot period and the synchronous time period;

synchronous detection slot width modulation (example):

enhancement (widening): td=td x N or Td0 x N,

slow down (narrow): td=td/N or Td0/N,

td and Td0 are the current and initial synchronization detection slot widths, respectively.

Step S102, when the wireless slave device receives the synchronous time identification sent by the wireless master device in the wireless detection time slot in the low-power consumption standby state, a synchronous matching state is established and maintained with the wireless master device according to the synchronous time identification.

In the implementation process, when the wireless slave terminal equipment receives the synchronous time identifier sent by the wireless master terminal equipment in the wireless detection time slot in the low-power consumption standby state, a synchronous matching state is established and maintained according to the synchronous time identifier and the wireless master terminal equipment, and a corresponding matching verification identifier is placed in the equipment state beacon.

In the implementation process, the device state beacon is a wireless beacon which reflects the characteristic attribute and the current physical state of the device and the associated object thereof and is fed back/transmitted by the wireless slave device in a response mode.

In the specific implementation process, the wireless master terminal adjusts the beacon broadcasting parameters of the wireless slave terminal equipment in the state beacon mode by establishing synchronous matching or wireless connection, wherein the beacon broadcasting parameters comprise a beacon broadcasting time interval, a beacon broadcasting duration time and a beacon broadcasting modulation parameter; when the wireless slave terminal equipment is in a synchronous matching state, the wireless slave terminal equipment adjusts the beacon broadcasting phase time based on the group sequence code and/or the matching code of the equipment, so that a plurality of wireless slave terminal equipment in the same synchronous matching state keeps a certain beacon broadcasting phase time difference.

The beacon broadcast interval time of the wireless master device is adaptively adjusted based on the change of the beacon broadcast configuration information thereof, including:

1) When the beacon broadcast configuration information is unchanged, the beacon broadcast time interval takes the conventional configuration parameters,

2) Once the beacon broadcast configuration information is changed (such as a matching request call, successful matching establishment and state control feedback) for N periods, the beacon broadcast is quickened, namely the short beacon broadcast interval time is shortened in a short period.

It should be noted that, when the wireless slave device is in the synchronous matching state, the wireless slave device adjusts its beacon broadcasting phase time based on the group sequence code and/or the matching code of the device itself, so that the plurality of wireless slave devices maintain a certain beacon broadcasting phase time difference in the same synchronous matching state;

the wireless slave device calculates its beacon broadcast phase time Δt according to the specified broadcast phase allocation code Ns:

△T＝△T0+Ns*τ

where Δt0 is the beacon broadcast phase time corresponding to the group sequence code being the starting sequence number (typically 0), τ is the minimum (reference) time difference for a given beacon broadcast phase;

the broadcast phase allocation code Ns is specified by the cooperative agent node; by default, the broadcast phase allocation code Ns is equal to the group order code to which it belongs in the group of devices;

typically, τ is taken to be greater than the beacon broadcast pulse width; alternatively, τ is taken as the allowed beacon broadcast slot width in a single period divided by the maximum group sequence code.

In a specific implementation, at least the following parameters can be derived from the collaborative matching parameters:

1) Matching verification codes: the association parameters of the currently matched cooperative agent network system, namely identifiable characteristic parameters of the same cooperative agent network system affiliated to a plurality of cooperative agent nodes, such as domain addresses and group numbers;

2) Service identification code: identification code information assigned to the wireless slave device different from other wireless slave devices.

In the implementation process, the group sequence code is a service identification code contained in the collaborative matching parameters, and is a member sequence number or identification code allocated to different wireless slave devices for a specified device group;

different device members in a specified device group are assigned different group codes by a cooperative proxy node in the cooperative proxy network system.

In the specific implementation process, the group sequence code is expressed into another form which is more suitable for bit selection comparison and identification and multiple selection superposition comparison through one-time conversion: the group sequence code is expressed in the form of a bit selection code, and the bit selection code of the wireless slave terminal equipment corresponds to the group sequence code and can be mutually converted; the bit select codes of the wireless slave device include bit byte offsets and single byte bit select codes.

When the same cooperative proxy network system comprises a plurality of cooperative proxy nodes, the service identification codes are allocated, and one of the following schemes is adopted:

scheme one, single service identity scheme: the service identification codes distributed by different cooperative agent nodes have the same property, and when a certain wireless slave terminal device establishes cooperative matching with one cooperative agent node through a matching request to obtain cooperative matching parameters comprising the service identification codes, the wireless slave terminal device is regarded as establishing a cooperative matching state with the cooperative agent network system and all the cooperative agent nodes thereof;

Scheme two, multi-service identity scheme: the service identification codes distributed by different cooperative agent nodes have independence, and when a certain wireless slave terminal device is matched with the establishment of a plurality of cooperative agent nodes, the service identification codes distributed by different cooperative agent nodes to the wireless slave terminal device are required to be obtained through matching response signals.

In the embodiment of the present invention, when a certain wireless master device needs to actively send data to a plurality of wireless slave devices in a low-power standby state, determining a predetermined mode and a plan parameter according to which to perform mode adjustment on the wireless mode parameter according to a balance mechanism of the number of target devices, response time and power consumption of data transmission, including: and adopting the wireless mode parameters to transmit data, and transmitting updated or preset wireless mode parameters to the wireless slave terminal equipment in a directional wireless broadcast or currently available wireless data transmission mode.

The mode adjustment includes a synchronization mode adjustment of an associated parameter of the synchronization detection mode (i.e., a synchronization detection time slot parameter). According to the adjustment orientation of the synchronous detection time slot duty ratio, the synchronous mode adjustment comprises synchronous enhancement adjustment and synchronous weakening adjustment, and the parameter value of the synchronous detection time slot duty ratio is respectively increased or reduced.

The mode adjustment further includes a low power state restoration adjustment: and carrying out recovery adjustment on the wireless mode parameters according to a preset mode, so that the wireless slave terminal equipment returns to the original low-power consumption standby state.

When the wireless slave terminal equipment is in a state beacon mode or a synchronous detection mode, the wireless master terminal equipment respectively sends wireless directional broadcasting in a beacon detection time slot or a synchronous detection time slot of the wireless slave terminal equipment so as to establish wireless connection or adjustment with the wireless slave terminal equipment, or establish a synchronous matching state with the wireless slave terminal equipment, or adjust wireless mode parameters of the wireless slave terminal equipment;

when concurrent group configuration is performed on a large number of distributed low-power consumption (especially battery-powered) off-line wireless slave devices (such as wireless sensors and Bluetooth beacons) (for example, bluetooth beacon message information, clock information, trigger condition information and response plan information are changed), a mode of low efficiency is adopted when wireless connection is established with each wireless slave device one by one respectively to transmit configuration data; after the wireless slave device completes the concurrent group configuration, the wireless slave device can automatically restore an initial wireless low-power consumption standby mode (optionally comprising completely closing the synchronous detection time slot); according to the low-power consumption standby mode of the patent, when the synchronous detection time slot duty is small enough, the synchronous detection time slot power consumption can be ignored; although the delay of the first trigger response is caused, in the case of small increase of power consumption, compared with the wireless connection mode, the synchronous matching state still brings about great improvement of efficiency group and convenience for the configuration of a plurality of equipment groups.

The wireless mode parameters comprise the associated parameters of the wireless Bluetooth equipment in a low-power standby state and a wireless transmission state, and the wireless master equipment performs wireless mode management including planning, reservation and switching on the wireless slave equipment through adjustment of the wireless mode parameters.

Typically, the wireless mode parameters include association parameters in a status beacon mode, a sync detection mode, and/or a wireless connection mode: 1) Beacon broadcast parameters associated with a status beacon mode, 2) sync detection slot parameters associated with a sync detection mode.

When the wireless slave device is in the synchronization matching state, the wireless mode parameter includes a given synchronization time parameter, and the synchronization time parameter is included in the synchronization sequence beacon.

The low power standby state is based on the following low power wireless mode parameters:

status beacon mode: duration Ts1, beacon transmission slot width T1;

synchronous detection mode: duration Ts2, synchronous detection slot width T2;

the synchronization time period is: ts=ts1+ts2;

the sleep or dormant state is entered at times other than the slot widths Td1, td 2.

When the status beacon mode is the connectable beacon mode, the slot width T1 includes a beacon transmission slot Tt1 and a beacon detection slot Tr1: t1=tt1+tr1.

Wherein T1/Ts is the transmission time slot duty ratio D1 of the status beacon mode, and T2/Ts is the detection time slot duty ratio D2 of the synchronous detection mode.

When the duty ratio D1 and D2 of the time slot is far smaller than 1, the relative low-power consumption standby state can be maintained; if the synchronous detection time slot width T2 tends to be very small relative to the synchronous time period Ts, so that the synchronous detection time slot duty ratio D2 is far smaller than the transmission time slot duty ratio D1, the additional power consumption duty ratio brought by the synchronous detection mode is very small, and the low-power consumption standby state with lower power consumption can be maintained; the following are typical configuration values for wireless mode time parameters for low power standby states:

t1 is of the order of mS, D1 is 1% (equivalent to N1 broadcasts per second);

t2 is of the order of 10mS, D2 is 0.1% (equivalent to N2 times per minute);

wherein N1, N2 are both approximately on the order of bits;

when the duty ratios D1 and D2 of the time slots are far smaller than 1, the relatively low power consumption standby state can be maintained.

If the synchronous detection time slot width T2 tends to be very small relative to the synchronous time period Ts, so that the synchronous detection time slot duty ratio D2 is far smaller than the transmission time slot duty ratio D1, the additional power consumption duty ratio brought by the synchronous detection mode is very small, and the low-power consumption standby state with lower power consumption can be maintained;

The following are typical configuration values for wireless mode time parameters for low power standby states:

t1 is of the order of mS, D1 is 1% (equivalent to N1 broadcasts per second);

t2 is of the order of 10mS, D2 is 0.1% (equivalent to N2 times per minute);

where N1, N2 are both approximately on the order of bits.

It should be noted that, the wireless slave device enters a potential trigger state of preparation or waiting for triggering, and the wireless master device or the wireless slave device judges that the current state approaches to the trigger condition in degree or probability based on the pre-plan according to the monitoring of the current associated variable and the event before the trigger condition is reached; when the wireless slave device enters a potential trigger state, the wireless slave device adjusts and/or feeds back modulation through a wireless mode parameter mode, so that the wireless slave device has faster trigger response to the incoming trigger control.

The potential trigger states include states (examples) made up of one or a combination of the following:

1. preparing an operation state: the user enters the APP or opens the control interface but does not start triggering operation yet;

2. event early warning state: approaching but not yet reaching an event triggering condition;

3. proximity touch state: the trigger source object enters the field of view but no trigger has been formed yet.

Further, the state feedback modulation is to perform synchronous time slot modulation according to the feedback of the state monitoring variable; state feedback modulation is a dynamic balancing mechanism between the expected trigger response characteristics (e.g., receive response time) to wireless data reception and the synchronous slot power consumption of the wireless slave device based on feedback of the state monitoring variables.

The synchronous detection time slot power consumption refers to power consumption of the wireless receiving equipment caused by synchronous detection; the sync detection slot power consumption depends on its sync detection slot duty cycle.

In the embodiment of the invention, the state monitoring variable is a monitoring physical quantity reflecting the current state characteristics of the equipment or the associated service object in the target object equipment;

when the state monitoring variable reaches or exceeds a set early warning value, correspondingly reducing the synchronous detection time slot duty ratio in the wireless mode parameter; otherwise, when the state monitoring variable is better than the set expected value, the synchronous detection time slot duty ratio is correspondingly adjusted up.

In step S103, the wireless slave device receives the synchronization modulation identifier in its synchronization detection receiving timeslot, and performs mode adjustment on the wireless mode parameter according to the synchronization modulation identifier in a predetermined manner (including performing synchronization mode adjustment, typically synchronization enhancement adjustment, on the synchronization detection timeslot parameter).

In the specific implementation process, after the wireless mode parameters are subjected to mode adjustment according to a preset mode, when the wireless slave terminal equipment receives the synchronous modulation identification sent by the wireless master terminal equipment in the synchronous detection receiving time slot, according to the synchronous modulation identification, synchronous time slot modulation corresponding to the synchronous modulation identification is executed, and the corresponding modulation verification identification is placed in the equipment state beacon.

When the wireless slave terminal equipment judges that the equipment or the service object thereof is in a potential triggering state, the wireless slave terminal equipment carries out state feedback modulation on the synchronous detection receiving time slot according to the associated state monitoring variable, and a modulation verification mark is put into the equipment state beacon.

Step S104, the wireless slave terminal device receives the group configuration synchronous data packet sent by the wireless master terminal device in the synchronous detection receiving time slot, and receives the synchronous data packet in a synchronous time slot modulation mode in the synchronous effective period.

In the implementation process, the wireless slave terminal device receives the group configuration synchronous data packet sent by the wireless master terminal device in the synchronous detection receiving time slot, receives the synchronous data packet in a synchronous time slot modulation mode in the synchronous effective period, and places the state verification code received by the current corresponding synchronous data packet into the device state beacon.

The synchronization time correction is that the wireless slave terminal equipment calculates time offset correction of self synchronization detection receiving time slots in a synchronization time period according to the synchronization time mark; the synchronization time correction is performed at most once in one synchronization time period, alternatively, it may be defined that the synchronization time correction is performed at most once in N synchronization time periods.

After each execution of the synchronization time correction, the synchronization time correction of the current N (N > =1) synchronization time periods is masked based on a given default cycle number N and/or a correction offset of the current synchronization time correction.

In the implementation process, the wireless time slot synchronization is that a plurality of wireless slave devices in a synchronous matching state keep time slot matching in the time domain through synchronous time correction between the synchronous detection time slot of the wireless slave devices and the synchronous transmission time slot of the wireless master device.

The synchronous detection receiving time slot comprises a synchronous detection time slot and a synchronous receiving time slot; the synchronous detecting/receiving time slot refers to the same or overlapped detecting/receiving time slot when a plurality of wireless slave end devices establish or maintain synchronous matching state with a certain wireless master end device.

The synchronous detection time slot parameter of the wireless slave device refers to a preset (comprising pre-configuration and dynamic adjustment) parameter when synchronous data information is not received; the synchronous data information comprises a synchronous sequence beacon and/or a synchronous data packet sent by wireless master terminal equipment which is synchronously matched with the synchronous data information; when the wireless slave device receives the synchronous data information in the preset synchronous detection time slot, the actual synchronous detection receiving time slot depends on synchronous time slot modulation and the receiving mode of the current synchronous data packet.

The synchronization sequence beacons are a series of wireless beacons which are transmitted in a wireless directional broadcast mode, serve a specified target device group and contain synchronization information; the synchronous sequence beacons are periodic wireless beacons which are sent based on synchronous time sequence triggering given by synchronous time parameters, and at least one or a group of wireless beacons containing synchronous information are sent in one synchronous time period; multiple wireless beacons are typically transmitted during a synchronization time period.

The synchronization beacon is a wireless beacon which is contained in the synchronization sequence beacon and is used for time sequence synchronization between wireless transceiver devices.

Further, the synchronization sequence beacon comprises a synchronization beacon identification code; the synchronous beacon identification code is information for indicating the ID of the synchronous data transmission; the synchronous data transmission ID is an irreversible code (such as a cyclic sequence code or a clock association code) in a short term for wireless data transmission from any same network domain or upper network node; therefore, the wireless slave device can judge the redundancy and the effectiveness of the synchronous data transmission ID received at this time only by comparing the synchronous data transmission ID received at this time with the synchronous data transmission ID which has been responded and processed last time (namely, last time).

It should be noted that the synchronization sequence beacon includes a packet synchronization sequence beacon, which is used to serve different or multiple target device groups; the packet sync sequence beacon is received to be identified by the wireless slave devices of different groups of target devices in any one or combination of the following ways:

1) Different device group IDs;

2) Different synchronization time periods or magnifications thereof;

3) Different synchronization beacon slot phases or widths.

The synchronous data packet is a data packet synchronous configuration data packet which is simultaneously and concurrently transmitted to a plurality of wireless slave devices by a wireless master device in a wireless time slot synchronous mode, namely a synchronous data packet containing configuration information.

In the specific implementation process, the wireless main terminal device carries out transmission process management on a series of synchronous data packets formed by splitting a complete data packet or a data block through a transmission task queue, wherein the transmission process management comprises a priority ordering mode and parameters of the transmission synchronous data packets; the retransmission-allowed limiting time is for completing all the transmission tasks in the transmission task queue.

When the wireless main terminal equipment monitors and judges that all members in the group member set have completed the synchronous data packet receiving task according to a multi-selection superposition comparison method for a synchronous data packet of a certain packet sequence code, the synchronous data packet is removed from the sending task queue until the sending task queue is emptied.

The state verification code fed back by the wireless slave terminal equipment comprises a multi-packet verification identifier corresponding to each sub-packet sequence code of the series of synchronous data packets.

Optionally, once the wireless slave device receives the synchronous data packet of each packet sequence code successfully, according to the received synchronous modulation identification, the wireless mode parameter of the wireless slave device can be adjusted according to a preset mode, so that intermittent power consumption which may need to wait for other slaves to receive the data packet is reduced.

Prioritization includes any one or a combination of the following: 1) A circular queue; 2) Transmitting a rotation condition: such as specifying a transmit time/number limit and/or receiving feedback success rate/number from the slave; 3) The current slave receives the success rate ranking of the feedback (typically lower priority).

The technical effect of sending process management is to improve the efficiency and success rate of sending complete data packets.

In the specific implementation process, the same wireless master terminal device establishes a synchronous matching state with different wireless slave terminal devices according to the dynamic balance requirements on standby power consumption and trigger response of the wireless master terminal device by using the same or different synchronous matching mode parameters;

and/or different wireless slave devices or target device groups are adjusted and configured according to different synchronous time parameters;

Comprising the following steps: 1) Single-period or multi-period synchronous matching; 2) Single-time slot or multi-time slot synchronous matching; 3) Single-multiplying power or multi-multiplying power period synchronous matching;

the synchronization matching modes are different in that the synchronization sequence beacon sent by the wireless master device comprises any one or combination of the following to establish a synchronization matching state with different synchronization matching mode parameters for different wireless slave devices or target device groups:

1) Multicycle synchronization matching: the synchronous sequence beacon sent by the wireless master terminal equipment comprises a plurality of different synchronous time periods;

2) Multislot synchronization matching: the same synchronous time period comprises a plurality of synchronous detection time slots with different detection phase time;

3) Multiple-rate period synchronous matching: based on the same synchronous time period, adjusting and configuring the synchronous time periods of different wireless main terminal devices according to different multiplying powers; i.e., the synchronization time period of the wireless slave device detection response is N times the synchronization time period reference value.

The synchronization validity period is the longest duration allowed after one synchronization time correction, i.e. the maximum time interval of two synchronization time corrections, for maintaining the synchronization matching state; equivalently, the synchronization valid period is a preset maximum time interval for the wireless slave terminal equipment in the synchronization matching state to receive the synchronization time identifier sent by the wireless master terminal equipment in the current matching state.

The wireless slave device performs at least one synchronization time correction during each synchronization validity period to maintain a synchronization match state: and starting a new synchronization valid period timing every time synchronization time correction is executed according to the synchronization time identification, otherwise, considering that the synchronization matching state is lost when the synchronization valid period timing exceeds the allowable maximum value.

Step S105, when the wireless slave device completes receiving the synchronization data packet, the wireless mode parameter is restored and adjusted according to a predetermined manner, so that the wireless slave device returns to and maintains the initial low power consumption standby state.

It should be noted that, in the implementation process, the synchronous group control code is a code for selecting a group control device or a group of devices and identifying a group control type/mode;

the synchronous group control code comprises a group control multiple selection code, wherein the group control multiple selection code is a code for performing multiple selection on all or part of members in one or more equipment groups to form a group member set.

The synchronous group control code comprises any one or combination of group control operation mode, group control multi-selection code and state operation parameter; the group control multi-option code includes a group multi-option code and/or a device multi-option code.

Based on the group sequence code of the collaborative matching parameter, the wireless main terminal equipment converts the group sequence code into a bit selection code; the group control multiple choice code is a code that superimposes the bit choice codes of all the device members contained in the group member set in a logical or manner.

In the implementation process, when the wireless master device receives the 'stackable' synchronous group control coding queue sent by the network system host in a short group control processing period, the latest group control multi-selection code and the group control multi-selection code executed by the current target can be overlapped according to logic OR, and the overlapped group control multi-selection code is used as the group control multi-selection code executed by the current target.

The composite group control multi-selection code is a synchronous group control code formed by compositing a plurality of group control multi-selection codes, wherein different group control multi-selection codes form different group member sets so as to perform different group control operation modes and/or state operation parameters on different group member sets in the same target equipment group.

In the implementation process, when different group member sets in the equipment group are in different wireless mode states defined by wireless mode parameters, different group control operation modes are applied to the different group member sets in the same target equipment group according to the composite group control multi-selection code, namely, wireless mode parameter adjustment information is synchronously transmitted so as to synchronously carry out multi-level trigger control on different wireless slave end equipment or multi-level trigger group control on the group member sets;

Multi-stage trigger control/multi-stage trigger group control means that, based on the wireless mode parameters or the adjustment scheme parameters thereof of the balance mechanism of response time and power consumption for different wireless slave devices or device groups thereof or group member sets thereof in the target device group, the designated group member sets are subjected to progressive trigger control (including preparation or immediate trigger control) based on the wireless mode state in a synchronous group control manner.

When the classification control identification code is a device group control identification code and the group sequence code of the wireless slave device is contained in the device group control code, the wireless slave device executes corresponding state control operation based on corresponding state operation parameters.

When the wireless master device receives that the state verification code fed back by one device member in the group member set is consistent with the monitored target value, the bit selection code of the wireless slave device is overlapped in the group control monitoring multi-selection code; comparing the group control monitoring multi-selection code with the group control multi-selection code, and if and only if the two codes are equal, completing the established operation task by all members in the group member set; equivalently, the single byte bit selection code E of the wireless slave terminal equipment and the corresponding byte R [ J ] of the group control monitoring multi-selection code pointed by the bit byte offset J are subjected to logical OR operation and are assigned to the group control monitoring multi-selection code: r [ J ] = R [ J ] ORE, namely the bit selection code of the wireless slave terminal equipment is overlapped in the group control monitoring multi-selection code.

The wireless master device monitors and judges whether all members in the group member set have completed state control operation in a multi-selection superposition comparison mode according to all state verification codes in the collected group member set; if not, continuing to transmit the synchronous sequence beacon containing the synchronous group control code within the designated limit time for allowing retransmission; if so, the transmission of the synchronization sequence beacon containing the synchronization group control code is stopped.

When the same cooperative agent network system comprises a plurality of cooperative agent nodes, the group control multi-selection codes need to be replaced by matched group control multi-selection codes obtained in the following way when group control feedback monitoring is carried out based on multi-selection superposition comparison; the cooperative agent node transforms the group control multi-option code G into a matched group control multi-option code GA based on the logical AND operation based on the current agent matched multi-option code A: ga=ganda, and group control feedback monitoring is performed by GA instead of G based on multiple choice superposition comparison.

When the wireless master terminal equipment is used as a cooperative proxy node to receive an equipment state beacon sent by the wireless slave terminal equipment in a direct matching state, the bit selection code corresponding to the group sequence code is overlapped in the matching monitoring multi-selection code; the cooperative agent node compares the matched monitoring multi-selection code with the agent matched multi-selection code based on a set matched monitoring period, and when the two codes are unequal, the matched monitoring multi-selection code is directly used for replacing the updated agent matched multi-selection code; equivalently, the single byte bit selection code E of the wireless slave terminal device and the corresponding byte S [ J ] of the matching monitoring multi-selection code pointed by the bit byte offset J are subjected to logical OR operation and are assigned to the matching monitoring multi-selection code: s [ J ] =S [ J ] ORE, namely, superimposing the bit selection codes in the device state beacon in the matched monitoring multi-selection codes; and the cooperative agent node judges that the wireless slave terminal equipment and the cooperative agent node are in a direct matching state or a non-direct matching state (namely, in the direct matching state of other agent nodes in the same cooperative agent network system) according to the matching verification identification in the equipment state beacon.

The state verification code is a verification mark for judging whether the data packet is received completely and whether the result state accords with the expected state; the state verification code comprises a multi-packet verification identifier corresponding to a series of synchronous data packets; the multi-packet verification mark is formed by superposition of multi-packet bit selection codes and/or data verification codes; the multi-packet bit selection code is used for carrying out bit selection setting on the receiving states in synchronous data packets of different sub-packet sequence codes, so as to form a state superposition identifier; the data check code includes check information for the received current synchronization data packet and/or the plurality of synchronization data packets.

When the wireless slave device receives a series of synchronous data packets formed by splitting a complete data packet in a plurality of synchronous detection receiving time slots, one or a combination of the following identification information corresponding to the current synchronous data packet is contained in synchronous data information (refer to a synchronous sequence beacon and/or the synchronous data packet itself): 1) A start address offset; 2) And (5) dividing the packet sequence code.

The byte length of the synchronous data packet is specified by a default value or a length identifier or an ending symbol; optionally, the identification information item further comprises a total packet number and/or a total length of the data packet split into synchronous data packets.

As can be seen from the technical solution of the present invention illustrated in fig. 1, the present invention is implemented by triggering a call to a low-power standby wireless receiving device: the wireless slave devices are in a low-power consumption standby state, and the wireless master device transmits wireless directional call broadcast containing a synchronous modulation identifier (used for switching wireless modes) in a specific wireless mode before transmitting a synchronous configuration data packet, so that the wireless mode is switched through call triggering before synchronous configuration, and the problem of call triggering to the low-power consumption standby wireless receiving device is solved; by balancing the wireless mode parameters of the receiving device with the reception power consumption: when the wireless slave device receives the synchronous modulation identification in the synchronous detection receiving time slot, performing mode adjustment on the wireless mode parameter according to a preset mode (including synchronous mode adjustment, usually synchronous enhancement adjustment, on the synchronous detection time slot parameter); the wireless mode parameters of the wireless main terminal equipment are subjected to balance planning and adjustment, so that the balance problem of the wireless mode parameters and the receiving power consumption of the wireless receiving equipment is solved; triggering response and receiving feedback through synchronous data transmission: the wireless slave terminal equipment starts receiving in the synchronous detection receiving time slot, receives the synchronous data packet in a synchronous time slot modulation mode, and puts the state verification code received by the current corresponding synchronous data packet into the equipment state beacon; therefore, the problems of triggering response and feedback receiving speed of synchronous data transmission are solved, and the flexibility and compatibility of synchronous data transmission and feedback execution are improved; balance of data reception and standby power consumption by wireless configuration: when the wireless slave terminal equipment completes the receiving of the synchronous configuration data packet, the wireless mode parameters of the wireless slave terminal equipment are restored and adjusted according to a preset mode, so that the wireless slave terminal equipment returns to and keeps an initial low-power consumption standby state; therefore, standby power consumption of the wireless receiving equipment in a non-data receiving state is avoided in most of time, and the problem of balance between wireless configuration data receiving and standby power consumption is solved.

The embodiment of the invention also discloses a wireless low-power consumption device, referring to fig. 2-5, the device is used as a wireless slave device, and receives a group configuration synchronous data packet sent by a wireless master device by establishing synchronous matching and wireless mode parameter adjustment, and the device comprises the following processing modules:

the synchronous matching module 201 establishes and maintains a synchronous matching state with the wireless master device according to the synchronous time identifier when receiving the synchronous time identifier sent by the wireless master device in the wireless detection time slot in the low-power consumption standby state, and places the corresponding matching verification identifier into the device state beacon;

the modulation receiving module 202 receives a group configuration synchronous data packet sent by the wireless master terminal device in a synchronous detection receiving time slot, receives the synchronous data packet in a synchronous time slot modulation mode in a synchronous effective period, and places a state verification code received by the current corresponding synchronous data packet into a device state beacon;

the mode adjustment module 203 receives the synchronous modulation identifier in the synchronous detection receiving time slot, and if the wireless mode parameter of the module is not matched, the module adjusts the wireless mode parameter according to the synchronous modulation identifier in a preset mode;

And the standby maintaining module 204 restores and adjusts the wireless mode parameters according to a preset mode when the wireless slave device completes the receiving of the synchronous data packet, so that the wireless slave device returns to the initial low-power consumption standby state.

Fig. 5 is a schematic diagram of a wireless network topology path and a role relationship for a low-power consumption target object device service provided in this embodiment, where the wireless network topology path and the role relationship reflect that a cooperative proxy node provides a cooperative proxy service for a low-power consumption target device group; the technical effect/value is that wireless mode adjustment and concurrent data service of the low-power consumption target object-oriented equipment are realized: the wireless cooperative aware core network (i.e., proxy Mesh) constructed by the cooperative proxy nodes provides cooperative proxy services for the low power consumption target device group based on device proxy management including wireless mode management.

In the specific implementation process, the average power consumption of the wireless slave terminal equipment in the low-power consumption standby state is far smaller than that in the wireless transmission state, and the wireless transmission state is a synchronous matching state or a wireless connection state established based on triggering control response; typically, the average power consumption in the low power consumption standby state is composed of the power consumption of the state beacon mode and the synchronous detection mode; the detection time slot duty ratio of the low-power consumption standby state is very low, so that the response time of the wireless slave device in the low-power consumption standby state for detecting and receiving the trigger control from the wireless master device is long; thus, when the wireless master device enters a potential trigger state, the wireless mode parameters of the wireless slave device need to be adjusted based on the synchronous slot modulation and/or the state feedback modulation.

Wireless low power devices, i.e., wireless devices in a low power standby state, which are any wireless devices requiring very low standby power consumption (typically several uA to several hundred uA) for battery power or other reasons, have not established wireless synchronization or wireless links with any wireless master device until they are not activated based on a trigger response.

The wireless beacon or the wireless electronic tag is used as a wireless low-power consumption device and further comprises an indication refreshing module, wherein the indication refreshing module is used for executing refreshing operation according to refresh mode parameters and refresh information appointed by received configuration data, and recovering and adjusting the wireless mode parameters in a preset mode based on the mode adjusting module, so that the wireless low-power consumption device returns to a low-power consumption standby state.

The wireless low power device includes: wireless beacons (e.g., bluetooth beacons, positioning beacons); wireless electronic tags (e.g., electronic price tags, equipment asset tags, mobile tags); wearable devices (e.g., smart bracelets, smart watches); wireless controlled devices (e.g., smart unit locks, mobile device locks) monitor sensors (e.g., temperature and humidity sensors, infrared sensors, proximity switch count sensors).

Wherein the wireless low power device implants a refresh check identifier (as a status check code) into the device status beacon immediately after performing an indication refresh operation in an immediate or timed manner.

The wireless master device collects the refresh verification identifications contained in the device status beacons and sent by all wireless slave devices in a wireless scanning detection mode, and verifies and monitors (including resending or suspending) the device statuses of all members and the execution progress of the refresh operation indicated in the device status beacons in a multi-choice superposition comparison mode.

In a specific implementation, the refresh processing management includes management of refresh timing/trigger conditions:

1) Refresh queue, priority: such as in the form of a refresh information pointer queue;

2) Refresh timing conditions: such as: immediate/timed, disposable/intermittent/rotation, duration or number of times;

3) Refresh trigger condition: such as: time interval conditions; local hardware trigger conditions, wireless trigger identification conditions.
