Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The network Energy-saving technology comprises intelligent fan speed regulation, Automatic Laser Shutdown (ALS), Energy Efficiency Ethernet (EEE), port dormancy, redundant power supply shutdown and the like. Taking EEE energy saving technology as an example, EEE is an energy saving method for dynamically adjusting power of an electrical interface according to network traffic. For a device equipped with a power self-adjusting function of an electrical interface, when the interface is in a service idle state (i.e., there is no network traffic in the interface), the device may reduce the power supply of the interface, i.e., the interface in the device automatically enters a power saving mode; when network flow exists in the interface, the equipment can recover the power supply of the interface, namely, the interface in the equipment automatically enters a normal working mode. However, these network energy saving technologies are all for wired devices, and cannot be applied to wireless devices in the internet of things. Therefore, the embodiment of the application provides a device energy saving method for wireless devices in the internet of things.
Fig. 1 is a schematic structural diagram of an internet of things provided in an embodiment of the present application. As shown in fig. 1, the internet of things includes a wireless device 101 and wireless internet of things terminals 102a-102c (collectively referred to as wireless internet of things terminals 102). The number of wireless internet of things terminals in the figure is only used as an exemplary illustration and is not used as a limitation to the internet of things provided by the embodiment of the present application.
Wherein the wireless device 101 may be an Access Point (AP) or other wireless access device. The wireless internet of things terminal 102 may be a smart meter, a smart lamp, a smart temperature sensor, a smart humidity sensor, or the like. The wireless device 101 and the wireless internet of things terminal 102 are connected through a wireless network. The wireless device 101 is configured to provide a wireless access service for the wireless internet of things terminal 102. The wireless internet of things terminal 102 is used for collecting internet of things service data and sending the internet of things service data to the wireless device 101 through a wireless network. Alternatively, the wireless network may be a ZigBee (ZigBee) network, a bluetooth network, a cellular mobile network, a Wireless Local Area Network (WLAN), or the like. Radio Frequency Identification (RFID) and other wireless communication technologies may also be used for wireless communication between the wireless device 101 and the wireless internet of things terminal 102, which is not limited in this embodiment of the present application.
Optionally, with continued reference to fig. 1, the internet of things further includes an internet of things gateway 103 and a network controller 104. The internet of things gateway 103 is connected with the wireless internet of things terminal 102 through the wireless device 101. The wireless device 101 is further configured to send the received service data of the internet of things sent by the wireless internet of things terminal 102 to the internet of things gateway 103. The internet of things gateway 103 is used for processing internet of things service data sent by the wireless internet of things terminal 102. The internet of things gateway 103 is also used for managing the wireless internet of things terminal 102. The network controller 104 is connected to the wireless device 101. The network controller 104 is used to manage the wireless device 101, and may configure, for example, the transmission channels of the wireless device 101. The internet of things gateway 103 and the network controller 104 may be independent devices or may be integrated with other devices. For example, the internet of things gateway 103 may be integrated with the wireless device 101. As another example, the internet of things gateway 103 and the network controller 104 may be integrated in one device.
Fig. 2 is a schematic flowchart of an apparatus energy saving method according to an embodiment of the present application. Can be applied to the internet of things as shown in fig. 1. As shown in fig. 2, the method includes:
step 201, the wireless internet of things terminal sends a negotiation request to the wireless device, wherein the negotiation request includes an internet of things service requirement of the wireless internet of things terminal.
Optionally, the service requirement of the internet of things of the wireless internet of things terminal includes an internet of things service data volume of the wireless internet of things terminal and/or an internet of things service data sending period of the wireless internet of things terminal. When the wireless internet of things terminal periodically sends the internet of things service data to the wireless device, the internet of things service requirement of the wireless internet of things terminal may include the internet of things service data sending period of the wireless internet of things terminal. The internet of things service data volume of the wireless internet of things terminal comprises the byte number, the message number and/or the internet of things service data sending time length of the internet of things service data needing to be sent by the wireless internet of things terminal. The internet of things service data volume of the wireless internet of things terminal may further include an internet of things service data sending rate of the wireless internet of things terminal, and the like, which is not limited in the embodiment of the application.
According to different application scenarios, the wireless internet of things terminal can periodically send internet of things service data to the wireless equipment and can also aperiodically send the internet of things service data to the wireless equipment. In the embodiment of the application, the wireless internet of things terminal can send the internet of things service data to the wireless device aperiodically, which means that the time interval for sending the internet of things service data to the wireless device by the wireless internet of things terminal is variable. For example, the wireless internet of things terminal is an intelligent temperature sensor, and the intelligent temperature sensor is used for monitoring the ambient temperature. When the intelligent temperature sensor monitors that the ambient temperature changes rapidly, the intelligent temperature sensor can send temperature data to the wireless equipment once every 3 minutes; when the intelligent temperature sensor monitors that the ambient temperature changes slowly, the intelligent temperature sensor may send temperature data to the wireless device every 5 minutes.
When the wireless internet of things terminal periodically sends internet of things service data to the wireless device, the wireless internet of things terminal can directly send a negotiation request to the wireless device after being connected with the wireless device. When the wireless internet of things terminal sends the internet of things service data to the wireless device aperiodically, the wireless internet of things terminal can send a negotiation request to the wireless device before the time interval for sending the internet of things service data needs to be changed.
Step 202, when the wireless device receives a negotiation request sent by the wireless internet of things terminal by using the wireless transceiver in the wake-up state, the wireless device sends a negotiation response to the wireless internet of things terminal by using the wireless transceiver, wherein the negotiation response comprises data of the wireless internet of things terminal at the time of sending the internet of things service data next time.
Optionally, the data of the wireless internet of things terminal about the time of sending the internet of things service data next time may include a specific value (i.e., a specific time point) of the time of sending the internet of things service data next time by the wireless internet of things terminal, and/or an interval duration between the time of sending the internet of things service data next time by the wireless internet of things terminal and the current time. The interval duration is used for indicating the wireless Internet of things terminal to send the Internet of things service data to the wireless equipment after the interval duration is received and the negotiation response is received. The interval duration may be effective only for sending the service data of the internet of things next time, or may be a period, that is, an interval between sending the service data of the internet of things twice. When the wireless internet of things terminal periodically sends the internet of things service data to the wireless device, the interval duration may be an internet of things service data sending period of the wireless internet of things terminal.
Step 203, the wireless device enters a sleep state before the time when the wireless internet of things terminal sends the internet of things service data next time, wherein the sleep state comprises the step of turning off the wireless transceiver.
Alternatively, the wireless device may enter the sleep state after completing data processing in the awake state. In the embodiment of the application, the wireless device enters the dormant state before the moment when the wireless internet of things terminal sends the internet of things service data next time, the wireless device can be always in the dormant state before the moment when the wireless internet of things terminal sends the internet of things service data next time, the wireless device can also be in the dormant state before the moment when the wireless internet of things terminal sends the internet of things service data next time, the wireless device is in the awakening state sometimes, and the wireless device is awakened when sleeping.
In most application scenarios, a wireless device is usually connected with a plurality of wireless internet of things terminals. The internet of things services corresponding to different wireless internet of things terminals may be different, and correspondingly, the internet of things service data sending periods of different wireless internet of things terminals may also be different.
Illustratively, it is assumed that the wireless device is connected with three wireless internet of things terminals, and internet of things service data transmission periods of the three wireless internet of things terminals are 5 minutes, 10 minutes and 30 minutes respectively. The wireless device enters the awake state every 5 minutes, and enters the sleep state again after completing data reception and processing in the awake state each time. For a wireless internet of things terminal with an internet of things service data sending period of 5 minutes, the wireless equipment is in a dormant state before the moment when the wireless internet of things terminal sends the internet of things service data next time. For the wireless internet of things terminal with the internet of things service data sending cycle of 10 minutes and 30 minutes, the wireless equipment is in a dormant state sometimes before the moment when the wireless internet of things terminal sends the internet of things service data next time, and is in an awakening state sometimes.
Further illustratively, it is assumed that the wireless device is connected with three wireless internet of things terminals, and internet of things service data transmission periods of the three wireless internet of things terminals are 5 minutes, 7 minutes and 13 minutes respectively. The wireless device enters the wake-up state in the 5 th minute, and enters the sleep state after completing data reception and processing in the wake-up state; the wireless equipment enters an awakening state in the 7 th minute, and enters a dormant state after completing data receiving and processing in the awakening state; the wireless equipment enters an awakening state in the 10 th minute, and enters a dormant state after completing data receiving and processing in the awakening state; the wireless equipment enters an awakening state in 13 th minute, and enters a dormant state after completing data receiving and processing in the awakening state; the wireless device enters an awakening state in the 14 th minute, and enters a dormant state after completing data receiving and processing in the awakening state; by analogy, the wireless device enters an awakening state at the beginning of the service data transmission period of the internet of things of each wireless internet of things terminal.
In the embodiment of the application, when the wireless device receives the negotiation requests sent by the wireless internet of things terminals in the awakening state, the wireless device can set the time when the wireless internet of things terminals send the internet of things service data next time to be the same time, so that the working periods of the wireless internet of things terminals are concentrated, the idle time of the wireless device is increased as much as possible, the sleep time of the wireless device can be increased, and the power consumption of the wireless device is reduced.
The wireless device can receive and process the internet of things service data sent by the wireless internet of things terminal in the awakening state, and can also receive and process non-internet of things service data such as connection requests and/or negotiation requests sent by the wireless internet of things terminal. After the wireless device enters a sleep state, the wireless device may turn off the wireless transceiver, i.e., the wireless device cannot receive or transmit data in the sleep state. Therefore, when the wireless internet of things terminal sends the negotiation request to the wireless device in step 201, the wireless device is in a dormant state, and the wireless internet of things terminal does not receive a negotiation response to the negotiation request. In the embodiment of the application, after the wireless internet of things terminal sends the negotiation request to the wireless device, the wireless internet of things terminal sends the negotiation request to the wireless device again when the negotiation response sent by the wireless device is not received within the target time length.
And step 204, the wireless equipment enters a light sleep state from the moment when the wireless Internet of things terminal sends the Internet of things service data next time so as to try to receive the data sent by the wireless Internet of things terminal.
The light sleep (doze) state can be any relative wake-up state power-saving working mode capable of being woken up by the wireless internet of things terminal. For example, the wireless device turns off the transmit rf circuitry of the wireless transceiver and turns on the receive rf circuitry of the wireless transceiver. The wireless device is unable to transmit data but is able to receive data in this mode of operation. The number of operational components of the wireless device in the operating mode is greater than the number of operational components of the wireless device in the dormant state and less than the number of operational components of the wireless device in the awake state.
Optionally, a timer may be set, and the wireless device is triggered to enter the doze state at the time when the wireless internet of things terminal sends the internet of things service data next time. The timer may be set in the wireless device, or may be set independently of the wireless device, which is not limited in this embodiment of the application.
Step 205, when the wireless device receives data sent by the wireless internet of things terminal in the light sleep state, the wireless device enters an awake state.
Optionally, the data sent by the wireless internet of things terminal may be internet of things service data, a connection request or a negotiation request, and the like. The data sent by the wireless internet of things terminal can also be a wake-up notification specially used for waking up the wireless device, and after the wireless device enters the wake-up state, a wake-up response can be sent to the wireless internet of things terminal and used for notifying the wireless internet of things terminal that the wireless device has entered the wake-up state.
In the embodiment of the application, the wireless device enters the light sleep state from the moment when the wireless internet of things terminal sends the internet of things service data next time, and when the wireless device receives the data sent by the wireless internet of things terminal in the light sleep state, the wireless device enters the awakening state again. Because the wireless device can receive the data sent by the wireless internet of things terminal in the shallow sleep state, and the energy consumption of the wireless device in the shallow sleep state is lower than that in the awakening state, the embodiment of the application ensures the reliability of the wireless device in receiving the data sent by the wireless internet of things terminal, and reduces the energy consumption of the wireless device as much as possible.
Optionally, the wireless device may also directly enter the awake state from the time when the wireless internet of things terminal sends the internet of things service data next time. Namely, the above steps 204 and 205 may be replaced by: and the wireless equipment enters an awakening state from the moment when the wireless Internet of things terminal sends the Internet of things service data next time.
And step 206, the wireless internet of things terminal determines the next time of sending the internet of things service data based on the negotiation response.
In one possible implementation manner, when the negotiation response includes a specific value of a time when the wireless internet of things terminal sends the internet of things service data next time, the wireless internet of things terminal determines that the time when the internet of things service data is sent next time is a specific time point included in the negotiation response.
For example, the specific value of the time when the wireless internet of things terminal sends the internet of things service data next time in the negotiation response is 11:05, and the wireless internet of things terminal determines that the time when the wireless internet of things terminal sends the internet of things service data next time is 11: 05.
In another possible implementation manner, when the negotiation response includes an interval duration between the time when the wireless internet of things terminal sends the internet of things service data next time and the current time, the wireless internet of things terminal determines that the time when the internet of things service data is sent next time is the time when the interval duration elapses after the time when the negotiation response is received.
Illustratively, the interval duration between the next time when the wireless internet of things terminal sends the internet of things service data and the current time in the negotiation response is 3 minutes, and assuming that the wireless internet of things terminal receives the negotiation response at 11:02, the wireless internet of things terminal determines that the next time when the internet of things service data is sent is 11: 05.
Optionally, when the negotiation response includes an internet of things service data sending period of the wireless internet of things terminal, the wireless internet of things terminal may determine a time for sending the internet of things service data each time based on the negotiation response.
For example, with reference to any example of the foregoing possible implementation manner, assuming that the internet of things service data transmission period of the wireless internet of things terminal is 5 minutes, the wireless internet of things terminal may determine that the time for transmitting the internet of things service data is 11:05, 11:10, 11:15, and so on.
Optionally, after the wireless internet of things terminal determines the time for sending the internet of things service data next time, a timer may be set in the wireless internet of things terminal, and the wireless internet of things terminal is triggered to send the internet of things service data at regular time.
And step 207, the wireless internet of things terminal sends the internet of things service data to the wireless equipment after the moment, and does not send the internet of things service data to the wireless equipment before the moment.
Because the wireless device does not receive the wireless signal before the moment, the wireless internet of things terminal does not send the internet of things service data to the wireless device in the period. For example, referring to the example in step 206, assuming that the wireless internet of things terminal sends the negotiation request to the wireless device at 11:00, and the wireless internet of things terminal determines that the time for sending the internet of things service data next time is 11:05, the internet of things terminal sends the internet of things service data to the wireless device after 11:05, and does not send the internet of things service data to the wireless device in the time period of 11:00-11: 05.
