Description

Method and system for adjusting power consumption of electronic equipment

Technical Field

Embodiments of the present invention relate to the field of reducing power consumption of electronic devices, and more particularly, to a method and a system for adjusting power consumption of an electronic device.

Background

This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Thus, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.

For portable devices with communication capabilities, the length of battery life is an important parameter. For example, after a communication chip (e.g., wifi chip) of the dictionary pen is connected to the AP hotspot, the power consumption of the dictionary pen is increased due to system network communication, and thus the endurance time of the dictionary pen device is shortened.

In the prior art, the problem of short endurance time of the portable device is generally solved by adopting the following modes:

firstly, the communication chip is improved, and the power consumption of the chip is reduced.

And secondly, the battery capacity is increased, and more energy supply is provided.

And thirdly, the power consumption is reduced by intermittently supplying power to the communication chip.

However, the difficulty of improving the communication chip itself is high, and the communication chip is not suitable for the use of the existing chip.

By increasing the capacity of the battery, the battery occupies a large space, which may result in an increase in the size of the portable device and affect the user experience.

By intermittently supplying power to the communication chip to reduce power consumption, there are the following problems: on the one hand, there is frequent message interaction at power state switching, resulting in additional power consumption. On the other hand, intermittent power supply is not suitable for a scenario in which the communication chip is required to continuously perform a partial function, for example, a scenario in which the communication chip is required to maintain a basic connection function.

Summary of The Invention

The present inventors have found that, in a portable device, the power consumption of a communication chip has a large influence on the cruising ability of a battery, and therefore, the present inventors have extended the cruising ability of the battery from the viewpoint of reducing the power consumption of the communication chip.

Changing the power consumption state of a communication chip is one of the effective ways to regulate the power consumption of an electronic device. Communication chips typically have two states, one being a low power consumption state, for example: several low power states defined by the MAC80211 protocol can still maintain basic communication with the main chip when the communication chip is in the low power state. The other is a normal power consumption state, for example, the communication chip is in the normal power consumption state during the process that the communication chip provides the network service to the application. According to the working state of the electronic equipment, the low power consumption state and the normal power consumption state of the communication chip are switched in time, so that the power consumption of the electronic equipment can be reduced.

The inventor finds that in the switching process of the communication chip between the low power consumption state and the normal power consumption state, the power consumption caused by message transmission can be reduced by improving the trigger condition for switching the states, and the method is also a method for further solving the battery endurance.

Having described the general principles of the invention, various non-limiting embodiments of the invention are described in detail below.

Application scene overview

Referring first to fig. 2, there is shown a hardware block diagram of a portable electronic device to which an embodiment of the present invention can be applied, as shown in fig. 2, such a portable device has its own functions and functions of communicating with the outside, and generally has at least a main chip 21 (including a CPU and a DDR memory) performing main software functions and a communication chip 22 performing communication functions. For example: the equipment such as dictionary pen, earphone, etc. is externally hung with a communication chip for realizing network communication connection outside the main chip. After a communication chip of the dictionary pen, such as a wifi chip, is connected to a wireless Access Point (AP), network communication of the communication chip may increase power consumption of the wifi chip of the dictionary pen, resulting in a reduction in endurance time of the dictionary pen device. The embodiment of the invention is used in the portable electronic equipment to reduce the power consumption of the electronic equipment and prolong the endurance time of the battery.

Exemplary method

In connection with the application scenario of fig. 2, a method for reducing power consumption of a communication chip according to an exemplary embodiment of the present invention is described with reference to fig. 3, fig. 4 and fig. 5. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.

Fig. 3 shows a system architecture hierarchy of an electronic device according to an embodiment of the invention. As shown in fig. 3, the system architecture hierarchy of an electronic device generally includes an application Layer 31, a HAL (Hadware Abstract Layer) Layer 32, a network interface Layer 33, and a hardware Layer 34.

The application layer 31 is provided with a plurality of applications, for example, a dictionary APP, a cloud note APP, and the like, and directly faces the user through an interface of the electronic device for user operation.

The HAL layer 32, also known as a hardware abstraction layer, is an interface layer between the kernel of the operating system and the hardware circuit, and is intended to abstract hardware, to hide the hardware interface details of a specific platform, to provide a virtual hardware platform for the operating system, to make it hardware-independent, and to be portable on a variety of platforms. The HAL layer may include various functional modules, such as GPS, vibrator, wi-Fi, copybit, audio, camera, and the like. In an embodiment of the invention, a low power consumption module is provided in the main chip for regulating the power consumption of the electronic device. The low power consumption module can be arranged at any position in the main chip. In some implementations, it may be preferable to locate the low power consumption module in the HAL layer 32 in view of the above-described characteristics of the HAL layer. The low power consumption module provided in the HAL layer 32 is connected to the application layer 31 and the network communication interface layer 33, respectively.

The network interface layer 33 is used to provide an interface for connection and communication. In some implementations, a network communication interface is provided for communication between the master chip and the communication chip.

The hardware layer 34 includes the hardware of the host chip itself and plug-in hardware, such as: the communication chip may be referred to as a "hardware one". The communication between the communication chip and the main chip is realized through a network communication interface in the network interface layer 33.

Fig. 4 shows a schematic flow chart of a method of regulating power consumption of an electronic device according to an embodiment of the invention. The method may be performed, for example, by the low power module in fig. 3. For clarity, fig. 5 shows a message interaction diagram of a method of adjusting power consumption of an electronic device according to an embodiment of the invention. This is described below in conjunction with fig. 4 and 5.

The low power consumption module disposed in the main chip 21 executes the following method, as shown in fig. 4, in step S1, the low power consumption module sends an inquiry message to the application layer 31 in the main chip 21 to inquire whether the application in the application layer 31 has a network connection requirement.

As shown in fig. 4, in step S2, in response to not receiving the corresponding reply message within the first preset period since the query message is sent, the low power consumption module sends a command to the network communication interface layer 33 to instruct the network communication interface layer 33 to stop sending the network connection request to the communication chip 22.

The first preset period is a limited time according to which whether the power consumption state of the communication chip 22 is switched is determined in the process that the low power consumption module executes the power consumption state switching of the communication chip 22, and the limited time is used for judging whether a trigger condition for switching the power consumption state of the communication chip 22 exists in the limited time. The first preset period may be adjusted as desired. In the embodiment of the present invention, a first preset period may be set according to the time taken for the communication chip 22 to switch the power consumption state, so that the time for sending the query message to the application in the application layer 31 matches the time for the communication chip 22 to enter the low power consumption state.

When the low power consumption module sends out the inquiry information, it starts timing, and when the timing exceeds the first preset period, it still does not receive the response message, and then the low power consumption module can execute the operation of making the communication chip 22 enter the low power consumption state. That is, the low power consumption module triggers the communication chip 22 to enter the trigger condition of the low power consumption state, and does not need any transmission of response message, and only needs to satisfy: no response message is received during the first predetermined period. Compared with the technical scheme that the power consumption state switching of the communication chip 22 needs to be triggered based on the fact that a certain message is received, the trigger mode reduces the power consumption caused by message interaction.

The scheme adopted for switching the power consumption state of the communication chip is as follows: the low power module sends a command to the network communication interface layer 33 instructing the network communication interface layer 33 to stop sending network connection requests to the communication chip 22. The communication chip defined in the embodiments of the present invention may be configured to have the following characteristics: when the network connection request is not received for a period of time, a low power state is entered. The commands sent to the network communication interface layer 33 are conventional commands, and the present invention is not described in detail.

The state switching of the communication chip 22 in the electronic device should have real-time performance so as to conform to the use scene of the electronic device by the user. Therefore, it is necessary to frequently transmit the inquiry message and to continuously re-determine the power consumption state of the communication chip 22.

In some implementations, when the transmission time interval of the two previous and next inquiry messages is decided, the transmission time of the next inquiry message may be determined in response to the corresponding response message received within a first preset period since the inquiry message was sent. That is, the sending time of the next inquiry message is adjusted in time according to the response message to match the requirement of the application.

In other implementations, the sending time of the next inquiry message may also be determined according to the second preset period and the corresponding response message received in the first preset period after the inquiry message is sent, that is, by referring to the two factors: the response message and a preset second preset period.

The second preset period refers to a preset time interval for sending the inquiry messages twice, and can be flexibly adjusted according to needs.

By referring to the response message and the second preset period, the requirements of the matching application and the requirements of other elements in the system can be synthesized.

In still other implementations, the time of transmission of the next inquiry message may also be determined based only on the second preset period. In this way, a constant interrogation message transmission interval can be maintained, maintaining stability in executing various instructions.

The second preset period may be set to any value of 25 to 35 seconds, and preferably, the second preset period is set to any one of 25, 30, and 35 seconds. The method and the device are applied to the portable equipment, the second preset period is set to be 25-35 seconds, the habit of a user for operating the portable equipment is met, and the use experience of the user can be improved.

In some implementations, the interrogation message may include an identification code, i.e., a different identification code may be included in each interrogation message sent. The response message at least comprises the corresponding identification code of the inquiry message and the application identification code of the response message. The identification code in the query message may be, for example, UUID, universal Unique Identifier (universal Unique Identifier), which is used to uniquely identify or distinguish query messages sent at different times.

The response message contains the identification code of the corresponding inquiry message, so that the low-power module can judge the inquiry message corresponding to the response message according to the identification code, and can accurately determine whether the time interval between the two is within the first preset period. The application identification code in the reply message, such as an APPID, may identify the application that issued the reply message.

Alternatively or additionally, the response message may further include network duration information required by the application, the network duration information being sent by the application for the duration required by the network service being used or required to be used. On this basis, in some embodiments of the present invention, the time for sending the query message next time can be determined according to the network duration information in the received response message and the sending time of the corresponding query message, and the power consumption state of the communication chip can be switched in time when the application does not need network connection.

Fig. 6 is a schematic diagram illustrating message interactions for returning a response message within a first preset period in the method for adjusting power consumption of an electronic device according to the embodiment of the invention.

As shown in fig. 6, among the applications included in the application layer 31, only an application that has a network connection requirement returns a response message corresponding to the inquiry message in response to the inquiry message. The application in the application layer 31 obtains the query message, first determines its own status, and determines the information of the network connection requirement, and if the application is performing network connection or there is a requirement for network connection, the application will return a response message. At this time, the low power consumption module does not need to send a command to the network communication interface layer, and still needs to process according to the conventional method.

That is, the receipt of the response message within the first predetermined period is the basis for the low power module not to send the command. In some embodiments of the present invention, since the response message is sent only by the application with the network connection requirement, and the other applications do not need to send the response message, the number of messages sent by the application layer 31 in the process is reduced, and the power consumption caused by message interaction is reduced.

In some embodiments of the present invention, the first preset period may be set to any value of 2 to 5 seconds, or set to any one of 2 and 3 seconds. Usually, the power consumption state of the communication chip is switched approximately in about 2-3 seconds, and some embodiments of the present invention may set 2 seconds or 3 seconds as a time interval for determining whether to switch to the low power consumption state, so that the first preset period can be kept consistent with the state switching time of the communication chip.

In some embodiments of the invention, the inquiry message may be sent in a broadcast form. By the scheme of sending the inquiry message in a broadcast manner, different applications can respectively make appropriate responses according to the needs of the applications.

In some implementations of the invention, the communication chip is a wifi chip. Take a wifi chip in a dictionary pen as an example: after the wifi chip of dictionary pen is connected the ap hotspot, be provided with the low-power module in the HAL layer, when the inquiry message of sending does not have corresponding response message to return, the network communication interface layer of the system of low-power module instruction dictionary pen stops application layer network request to the sending of wifi chip, and the power consumption of dictionary pen wifi chip falls to less than 200ua this moment for the wifi chip of dictionary pen is connected the heartbeat with the ap and is kept. When the HAL layer sends the inquiry message and receives a response, the dictionary pen wifi exits the low power consumption mode, the system network communication interface layer of the dictionary pen sends an application layer network request, at the moment, the power consumption of the dictionary pen wifi chip needs 70ma additionally, and after the network request is completed, the wifi can enter the low power consumption mode again to achieve the purpose of saving the power consumption.

For example: the battery capacity of the dictionary pen is 1000mwh, the power consumption of the dictionary pen when requested by a network is 250ma, and the endurance of the dictionary pen can be improved from 4h to 5.5h by using the technical scheme of the embodiment of the invention.

Fig. 7 shows a flow chart of a method for regulating power consumption of an electronic device according to the invention when the method is run in the electronic device.

As shown in fig. 7, in some embodiments of the present invention, the second predetermined period is set to 30 seconds as an example. Starting the electronic device and entering step 71: and starting. Then step 72 is entered: sleep for 30 seconds, and after waiting for 30 seconds of the sleep time, proceed to step 73: the low power module in the electronic device broadcasts a query message "whether the application layer makes a network request" to the application layer, and then proceeds to step 74, determines whether a response is received within a first predetermined period, and when a response is received, returns to step 72, waits again for 30 seconds, and broadcasts the query message again. When no response is received within the first predetermined period, the method enters step 75, controls the wifi chip to enter the low power consumption state, then enters step 76, waits for 30 seconds again, enters step 77, controls the wifi chip to exit the low power consumption state, and enters step 73 again to broadcast the inquiry information.

Exemplary device

According to different application scenarios, the power consumption adjusting method of the embodiment of the invention can be applied to different electronic devices, such as but not limited to small robots, printers, scanners, tablet computers, smart terminals, PC devices, internet of things terminals, mobile phones, driving recorders, navigators, sensors, cameras, video cameras, projectors, watches, earphones, dictionary pens, mobile storage, wearable devices, visual terminals, auto-pilot terminals, vehicles, home appliances, and/or medical devices.

In the embodiment of the invention, the triggering condition for switching the state of the communication chip by the low-power-consumption module is set as that the communication chip can be switched into the low-power-consumption state without receiving the response message within a certain time, so that the switching condition is simplified, the communication messages required for switching the communication chip into the low-power-consumption state are reduced, and the power consumption is reduced. Furthermore, the response message is sent only by the application with the network connection requirement, so that the amount of the response message is reduced, the communication messages required by switching the states are further reduced, the power consumption is reduced, and the endurance time of the battery of the electronic equipment can be prolonged. By setting the first preset period to be close to the state switching time of the communication chip, the frequency of sending the inquiry message and the frequency of switching the state can be coordinated with each other. By setting the second preset period to be about 30 seconds, the operation habit of the user is met, and the use experience of the user is improved.
