In the existing related art, the receiving device needs to send inquiry data to the intelligent gateway every preset period, so as to actively inquire whether there is application data that needs to be delivered to the current receiving device. Since it is relatively power-hungry for the receiving device to send query data to the outside world, the interval for sending the query data is generally adjusted to be longer, resulting in poor response time. In this case, the monitoring can be carried out for a longer time, and the embodiments of the present invention provide a device wake-up method, device and system based on the ZigBee communication protocol.

As shown in FIG. 1 and FIG. 2 , the device wake-up method based on the ZigBee communication protocol according to the embodiment of the present invention includes:

Step S11: When in the dormant state, do not send monitoring information until the accumulated first preset time period is reached, and switch to the receiving state; in this embodiment, the method described is applied to the receiving device 100, and in practical applications , the receiving device may be a communication device that performs data transmission based on the ZigBee communication protocol, for example, a smart door lock, a single fire switch, a temperature sensor, and the like. The receiving device 100 switches back and forth between the sleep state and the receiving state. The duration of the receiving state of the receiving device 100 is T1, and the duration of the sleep state is T2, that is, the first preset time period is T2, and the second preset time period is T1. The sleep state is actually a state in which monitoring information is not sent to an external device. At this time, the power consumption of the receiving device 100 is very low. The monitoring information is used to monitor whether an external device (eg, the central device 200 ) sends wake-up information. In an actual application scenario, the central device is a device that sends valid data, such as an intelligent gateway device.

Exemplarily, when the receiving device 100 is in a dormant state, at this time, the monitoring information will not be broadcast to the external device, that is, it will not monitor whether the external device sends wake-up information. The power consumption of the receiving device 100 at this time is low, saving energy. energy, the duration of the sleep state is T2.

Step S12: when in the receiving state, broadcast monitoring information to monitor whether the central device 200 sends wake-up information; when the monitoring central device 200 does not send the wake-up information within the second preset time period, switch to the dormant state; in this implementation For example, the receiving state is a state in which the receiving device 100 can broadcast monitoring information to the outside to monitor whether the external device sends wake-up information; the wake-up information is the information sent by the central device 200 to wake up a certain receiving device. Specifically, the state in which the receiving device 100 switches back and forth between the sleep state and the receiving state may be referred to as a periodic wake-up state.

Step S13 : when the center device 200 is monitored to send the wake-up information within the second preset time period, keep in the receiving state, and receive the valid data information sent by the center device 200 . In this embodiment, in the second preset time period, that is, in the T1 time period, the receiving device 100 is always in the receiving state. At this time, if the receiving device 100 is in the receiving state, the broadcast monitoring information is monitored. When the wake-up information is sent to the central device 200, the receiving device 100 will continue to remain in the receiving state. Specifically, the receiving device 100 can send feedback information to the central device 200, and the feedback information Valid data information is transmitted to the receiving device 100 .

Exemplarily, after receiving the valid data information sent by the central device 200, that is, after receiving the application data sent by the central device 200, the receiving device 100 switches back to the sleep state, that is, switches back to the periodic wake-up state, and continues to Alternate back and forth between a receive state for a duration of T1 and a sleep state for a duration of T2.

Exemplarily, after receiving the feedback information sent by the receiving device 100, the central device 200 starts to send valid data information to the receiving device 100, and the time length for the central device 200 to send the valid data information may be T4, that is, after the receiving device 100 After the 100 is awakened by the wake-up information sent by the central device 200, it will always be in the receiving state and start to receive the valid data information sent by the central device 200. Return to periodic wake-up state. That is, after the wake-up device receives the application data, it re-enters the periodic wake-up state through the timeout mechanism.

In this embodiment, the wake-up information will carry the address information of the receiving device 100 that the central device 200 wants to wake up, that is, the first device address information. The receiving device 100 that broadcasts the monitoring information is also stored in the preset address information, which is used to indicate the mac address of the current receiving device 100 . When the first device address information in the wake-up information is the same as the address information of the current receiving device 100 , it is determined that the current receiving device 100 is the device that the central device 200 wants to wake up, that is, the wake-up information has passed the verification of the current receiving device 100 .

The device wake-up method based on the ZigBee communication protocol provided by the embodiment of the present invention, combined with the comparison of the first device address information and the preset address information in the wake-up information, ensures that the central device will only wake up the designated receiving device, and will not wake up the device. It affects other receiving devices, thereby ensuring the security of effective data transmission and further reducing energy consumption.

As an optional implementation manner of the present application, the device wake-up method further includes:

When the address information of the first device is different from the preset address information, it is determined that the wake-up information does not pass the verification, and the device switches to the sleep state. In this embodiment, when the device mac address information carried in the wake-up information is different from the mac address of the current receiving device 100, it is determined that the wake-up information has not passed the verification of the current receiving device 100, and the current receiving device 100 continues to be in the receiving state When the second preset time period is accumulated, it will automatically switch to the sleep state.

As an optional implementation manner of the present application, in order to make the low-power consumption device, that is, the receiving device, in a dormant state most of the time, the first preset time period in this embodiment of the present invention needs to be greater than the second preset time period . In this embodiment, the receiving device 100 switches back and forth between the receiving state and the sleep state, the duration of the receive state is T1, and the duration of the sleep state is T2. Generally speaking, T2 is greater than T1, so as to achieve The effect of reducing power consumption.

Preferably, the duration of T2 can be far greater than the duration of T1. In order to save the power consumption of the receiving device 100, the smaller the ratio of T1/T2, the lower the power consumption of the receiving device. For example, T1 can be 20us, T2 can be 1-3s. Through this setting method, the low-power device can monitor the air data at regular intervals, so it can achieve a longer monitoring time under the condition of consuming the same power.

As an optional embodiment of the present application, in order to ensure that the device can be woken up reliably, that is, no matter what state the receiving device 100 is in when the central device 200 starts to send the wake-up information, the wake-up information can always be received. Therefore, It is set that the time period during which the center device 200 sends the wake-up information is greater than the sum of the first preset time period and the second preset time period. In this embodiment, in order to ensure that when the center device 200 sends the wake-up information, the receiving device 100 will definitely receive it. Therefore, the duration T3 for the center device 200 to send the wake-up information is set to be greater than the first preset time period T2 and the The sum T5 of the second preset time period T1, that is, T3>T5. That is, the time for the wake-up data sent repeatedly by the central device 200 is longer than the device wake-up and receiving state period, which ensures the reliability of the device being woken up. The smaller T5 is, the faster the receiving device is woken up.
