FIG. 4 is a schematic structural diagram of another sleep function device according to an embodiment of the present invention. FIG.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the scope of the present invention are within the scope of the invention.

Embodiments of the present invention provide an information transmission method, mainly when an SED device is added to an operation network or added to an allocation. After the network is commissioned, the method for receiving information sent by the group device in the network, wherein the group device may be a device such as Coordinate management in the network, and the SED device may include the Zigbee wireless network. The method of the present embodiment is a method performed by the SED device. The flowchart is as shown in FIG. 1. The method includes the following steps: (101), determining whether the information sent by the group device is received within a preset time window. If yes, steps (102) and (103) are performed, and if no, step (104) is performed. The time window of the preset includes several sub-time windows, and the duration of each sub-time window is a time interval for sending a polling message.

It can be understood that, in the distribution network, the group device can configure parameters on the SED device in the network, such as network resources or restriction information, and enter the operation network after the configuration of the SED device is completed, so that the network is allocated. In the middle of the road, the group device sends configuration information to the SED device. During the configuration process, when a SED device joins the distribution network, the SED device needs to start a preset time window, and sends a polling message to the group device within the preset time window to learn the group device. Configuration information sent to the SED device in the distribution network.

Under the operating network, the group device performs coordinated management of the network on other devices, and can send some management information to other devices, such as sending a read command, a binding request, or a report configure command. Wait for the command to be given to other devices. In this process, when an SED device is added to the operating network, the SED device initiates a preset time window and sends a polling message to the group device within the preset time window to learn the group device. Sent to the SED device in the operating network The operation information, the time window of startup will change with the amount of data.

Which takes into account the distribution network and the operating network, group settings The frequency difference of the information to be sent, the time window started under the distribution network and the time window started under the operation network may be the same or different, and the preset time window may include several (such as n, n For an integer time window greater than 1, the duration of each sub-time window is the time interval (gap) at which the SED device sends a polling message, and the number of sub-time windows is the number of times the SED device sends a polling message ( Times), the preset time window is (gap)*(times). For example, if an SED device sends 5 polling messages and sends them every 4 seconds (s), the time window preset in the SED device It is 4s*5=20s.

If the SED device is not received within the preset time window The information sent by the group device (operation information or configuration information) needs to enter a sleep state to save the power consumption of the device; if the SED device receives the information sent by the group device every time within the preset time window, the group is considered to be the group. The group device may then also send information, the SED device cannot stop sending the polling message, and the frequency of data polling needs to be maintained, then steps (102) and (103) are performed to ensure that when the group device is transmitting information. The SED device is in the data polling state to receive the information sent by the group device. The communication between the SED device and the group device can pass through the routing device.

It should be noted that the SED device is within the preset time window. Within the interval of sending the polling message, it is sleepy in the sub-time window, and is only awakened when the polling message is sent. The general awake state lasts for tens to hundreds of milliseconds. For example, the SED device is woken up in the first few hundred milliseconds, and sends a polling message to the group device to receive the group device to send. After the information, the SED device goes to sleep, and after 4 seconds the device is awakened for hundreds of milliseconds for polling.

Step (102), resetting a preset time window in the SED device, The time window that is about to start is set to a preset time. For example, when a time window of 20s is started in the SED device, during the process of sending the polling message, the time window of the startup changes with the amount of data, when in 5s. When the SED device receives the information sent by the group device, the time window is reset to 20s.

Step (103), sending a polling message within the reset time window Give the group device to receive information sent by the group device under the operating network or the distribution network.

Step (104), entering a sleep state for a long period of time, and at a certain Wake up after the time.

It can be understood that when the SED device goes into sleep for a long period of time Afterwards, the user can wake up the device by operating the SED device, for example, issuing a wake-up command for the user operation to the SED device; and the SED device can be automatically woken up after a certain time according to the configuration of the device. In the long-term sleep process, if the group device has information sent to the SED device, if the SED device is found to be in a sleep state, the sent information is first cached, and when the SED device is woken up, a message is sent to the group device. Wake up the indication message so that the group device will send the cached information to the SED device.

It can be seen that, in the embodiment of the present invention, when the SED device is in a preset After receiving the information sent by the group device in the time window, the preset time window is reset, and a polling message is sent to the group device within the reset time window. In this way, the SED device adjusts the SED setting according to the information sent by the group device. The frequency of sending the polling message is kept, so as to adjust the duration of the SED device in the awake state, and ensure that the SED device is in the awake state to receive the information sent by the group device during the period when the group device sends the information.

The SED device can slide through the above steps (101) to (104) The time window, the number of sub-time windows included in the specific time window and the duration of the sub-time window are constant. In a specific embodiment, the SED device performs the above steps (101) to (104), The preset time window may be adjusted according to a certain policy, such as shortening or extending the time window. Specifically, the SED device may determine whether the density of the information sent by the SED device by the group device is greater than a preset upper limit. If yes, it indicates that the group device sends each message to the SED device at a shorter interval. The SED device can increase the frequency of sending the polling message and send the polling message according to the increased frequency, so that the SED device can be guaranteed to wake up. Continuity and increase the time that the SED device is in the awake state to receive information sent by the group device at a high density. When the frequency of sending the polling message is increased, the SED device may shorten the duration of at least one sub-time window in a preset time window, and may also increase the preset time. The number of sub-time windows included in the window, and the duration of the sub-time window can be shortened at the same time.

If the SED device receives the density of information sent by the group device Not higher than the preset upper limit value or the density of the transmitted information is less than a lower limit value, indicating that the time interval for the group device to send each information to the SED device is long, the SED device does not need to send the polling message to the group at a high frequency. The group device, the SED device can reduce the frequency of sending polling messages and send polling messages according to the reduced frequency, which can save power consumption of the SED device. its When the SED device reduces the frequency of sending the polling message, the duration of the sub-time window may be increased when the number of sub-time windows is constant; and the sub-times included in the preset time window may also be reduced. The number of time windows, and can increase the duration of the sub-time window at the same time. Thus, after adjusting the time window, the duration of each sub-time window included in the time window may or may not be equal.

The upper limit of the preset is greater than the lower limit, and the SED device is connected. The density of the information sent by the group device may indicate the interval at which the group device sends each information. Specifically, the SED device may determine whether the density is greater than a preset upper limit value or less than a preset lower limit value. Determining within a few tens to hundreds of milliseconds when the SED device is woken up to send a polling message, and the density can be measured according to the time interval between receiving the two pieces of information sent by the group device, and according to the result of the judgment Adjust the time window.

And it should be noted that the preset time window described above is The duration of each sub-time window included may be equal or unequal; and when the time window is adjusted, the duration of the sub-time window may be increased or decreased linearly or non-linearly, such as when the sub-time window 1 is Increase a by length and increase the duration of sub-time window 2 to 2a.

In another specific embodiment, under the distribution network, The configuration information sent by the group device to the SED device is important, and the SED device needs to continuously send the polling message to receive the configuration information sent by the group device, for example, by adjusting the SED device to send the polling message under the distribution network. The frequency is implemented, which may be adjusted according to the density of the configuration information sent by the SED device to the group device.

Specifically, the SED device under the distribution network can specifically pass through Perform the following steps to transfer information to adjust the send polling The frequency of the information, as shown in FIG. 2, includes: step (201), determining whether the configuration of the group device to be sent under the distribution network is received within a preset time or when a preset time window is exceeded. The information, if not, indicates that the group device does not send the configuration information during the time when the SED device is in the awake state, the density of the configuration information sent by the group device is small. To save the power consumption of the SED device, the step (202) may be performed. Go to (204); if yes, perform step (205) to send the polling message according to the preset time window. The preset time needs to be less than or equal to the duration of the preset time window.

Step (202), reducing the frequency of sending the polling message. specific The time length of the sub-time window may be increased if the number of sub-time windows included in the preset time window is constant, and the number of sub-time windows included in the preset time window may also be reduced. The duration of the sub-time window can be increased while reducing the number of sub-time windows included in the preset time window.

Step (203), sending a polling message to the reduced frequency to Group device.

Step (204), when receiving the group device, sending the distribution network The configuration information sent is restored to use the preset time window to send a polling message to the group device, that is, the polling message is sent using the time window before the adjustment.

For example, when a SED device does not receive for a long time To the configuration information sent by the group device, the SED device can increase the length of the sub-time window that was originally 5s, for example, from the original 5s to 6s, so that the frequency of the SED device sending the polling message is reduced from 1/5s. Up to 1/6 s, in this process, as soon as the configuration information sent by the group device is received, the frequency of one time /5 s is resumed to send the polling message.

It should be noted that when the SED device receives the group device, After the configuration information is sent, after the SED device is configured according to the configuration information, the restart program can be triggered to restart the SED device, so that the SED device enters the operating network.

It can be seen that in this embodiment, when in the distribution network, the SED The device adjusts the frequency of sending the polling message by the SED device according to whether the status of the configuration information sent by the group device is received, and ensures that the SED device is in the awake state and receives the group device during the period when the group device sends the configuration information. The configuration information sent, and at the same time when the density of the configuration information sent by the group device is small, the power consumption of the device is saved by reducing the frequency at which the SED device sends the polling message.
