Modern processors, System On Chip (SOC), single-Chip computing units mostly support standby sleep and external interrupt wake-up functions.
The invention provides a power consumption optimization method for slave equipment of a 2.4G wireless audio system with a battery. The 2.4G wireless audio system comprises two devices, namely a host (host) and a slave (slave), wherein the host is normally connected with a power supply, and the slave is provided with a battery and a charging device and has three states of starting, shutting down and waiting. The power consumption optimization method can lead the slave to automatically adjust the self startup and standby states according to the startup and shutdown state of the host under the condition that the battery is not charged, lead the slave to automatically enter the standby state when the host is shut down, lead the slave to automatically start and be automatically connected with the host when the host is started, lead the slave to achieve the purposes of reducing the power consumption, prolonging the endurance time and not influencing the use of users through reasonable automatic dormancy and awakening strategies when the host is powered on and works.
The application specifically provides a power consumption optimization method of a 2.4G wireless audio system, and referring to fig. 1, the 2.4G wireless audio system comprises a host and a slave, wherein the host comprises a first processor and a first 2.4G module, which are connected through a communication bus; the slave comprises a second processor and a second 2.4G module which are mutually connected through a communication bus, the second 2.4G module is electrically connected with a wake-up pin of the second processor in a one-way mode, and the second processor is externally connected with a loudspeaker and a microphone; the first 2.4G module and the second 2.4G module are connected based on an audio channel and a signaling channel; the audio channel is used for transmitting audio coding data, and the signaling channel is used for transmitting various types of instruction data;
the host computer is responsible for networking, computing, displaying, playing multimedia, UI (User Interface) interaction and other functions, such as television, projection, commercial flat lamp multimedia interaction equipment. The slave has two functions of recording (MIC, microphone) and playing (speaker), which are equivalent to the expanded wireless MIC and wireless speaker of the master, and the master is connected and communicated with the slave through a 2.4G wireless connection module. In addition, the slave machine is provided with a battery for convenient movement. When the slave is not charged, the slave works by supplying power by the battery.
After the slave and the host are connected with the first 2.4G module through the second 2.4G module, an audio channel and a data channel are established, the audio channel transmits audio coding data, and a signaling channel transmits instruction data;
an I2S (Inter-IC Sound, audio Bus built in integrated circuit) interface is adopted between a second processor and a second 2.4G module of the slave computer to transmit audio coded data, a UART (Universal Asynchronous Receiver/Transmitter) interface is adopted to transmit instruction data, and a USB (Universal Serial Bus) interface is adopted between a first processor and a first 2.4G module of the host computer to simultaneously transmit the audio coded data and the instruction data.
Referring to fig. 2, the power consumption optimization method includes the steps of:
step S10, after the host computer is started, the first 2.4G module broadcasts the broadcast signal containing the connectable identification in the signaling channel continuously;
after the host is started, the first 2.4G module of the host continuously broadcasts a broadcast signal containing a connectable identifier in a signaling channel to tell a slave machine scanning the signaling channel that the host can establish wireless connection; the slave scans the signaling channel, detects that the broadcast signal of the host includes the connectable identification, and the slave knows that the host is powered on at the moment and can establish wireless connection.
Step S20, after the slave is started, the second 2.4G module scans the signaling channel, and after receiving the broadcast signal which is broadcast by the host and contains the connectable identifier, the second 2.4G module of the slave is connected with the first 2.4G module of the host in the air;
step S30, the second processor of the slave computer detects whether the disconnection duration of the second 2.4G module and the first 2.4G module of the master computer is longer than a first preset duration; if the second processor detects that the disconnection duration is longer than the first preset duration, the second processor controls a second 2.4G module, a loudspeaker and a microphone of the slave to enter a standby state, then the second processor enters the standby state, and the second 2.4G module sets a timer to be interrupted by itself;
after the second 2.4G module of the slave machine establishes an over-the-air connection with the first 2.4G module of the master machine, the second processor of the slave machine periodically detects whether the second 2.4G module is normally connected with the first 2.4G module of the master machine, specifically, the second processor of the slave machine sends a query instruction to the second 2.4G module through the UART interface, and the second 2.4G module returns a connection state (connection or disconnection) to the second processor, so that the second processor timely detects whether the second 2.4G module is normally connected with the first 2.4G module of the master machine.
After the host is shut down or the slave is far away from the host and exceeds the working range, the second processor of the slave detects that the second 2.4G module is disconnected with the first 2.4G module of the host, and the second processor counts the disconnection duration of the disconnection between the second 2.4G module and the first 2.4G module. If the disconnection duration is longer than a first preset duration (for example, 30 seconds), the second processor of the slave computer sends an instruction to the second 2.4G module of the slave computer through the UART interface to enable the second 2.4G module of the slave computer to enter a standby state (namely, a standby working mode), then the second processor of the slave computer closes an external loudspeaker and a microphone, and then the second processor of the slave computer also enters the standby state, so that the whole system of the slave computer enters the standby state, and the power supply of a battery of the slave computer is saved.
In addition, the second 2.4G module is also a system on chip, and the second 2.4G module has an operation unit inside, and after receiving the standby instruction sent by the second processor, the second 2.4G module automatically sets a timer interrupt and then enters a standby state, and after the timer interrupt is finished, the second 2.4G module can be awakened to work again.
Step S40, when the timer of the second 2.4G module of the slave machine is interrupted and the time is over, the second 2.4G module is automatically waken up; the second 2.4G module scans a signaling channel and monitors whether the first 2.4G module of the host broadcasts a broadcast signal containing a connectable identifier within a second preset time;
step S50, if the second 2.4G module does not monitor the broadcast signal containing the connectable identifier within a second preset time period, the second 2.4G module enters a standby state and sets the timer to interrupt itself again; if the second 2.4G module monitors the broadcast signal containing the connectable identifier within a second preset time, the second 2.4G module establishes an air connection with the first 2.4G module of the host and exits from a standby state, and the second 2.4G module sends a wake-up pulse to a wake-up pin of the second processor to wake up the second processor of the slave.
After the second 2.4G module of the slave is awakened from the timed dormancy standby, the second 2.4G module of the slave starts scanning the signaling channel, and monitors whether the first 2.4G module of the master starts working, if the broadcast signal containing the connectable identifier of the first 2.4G module of the master cannot be scanned within a second preset time (generally set to 100ms), the second 2.4G module of the slave enters the set timer interrupt again to be timed dormancy, and the process is repeated. In practice, the interval of the timer interrupt automatic wake-up of the second 2.4G module of the slave is most suitable in 2-5 seconds, excessive power consumption is avoided, and the state of the host can be detected at the first time.
When the host is powered on again or the slave returns to the working range of the host, the first 2.4G module of the host continuously sends a broadcast signal containing a connectable identification in a signaling channel. The slave second 2.4G module can sense the broadcast signal which is broadcasted by the host and contains the connectable identification after waking up from the timed dormancy, and after sensing the broadcast which can be connected with the host, the slave and the host establish connection again and exit the dormant state.
And after the second 2.4G module of the slave is connected with the first 2.4G module of the host and exits from the sleep standby state, sending a wake-up pulse to a wake-up pin of a second processor of the slave to wake up the second processor of the slave to start working.
In this embodiment, the slave second processor detects whether the disconnection duration of the second 2.4G module and the first 2.4G module of the master is longer than a first preset duration; if the disconnection duration is longer than the first preset duration, the second processor controls a second 2.4G module, a loudspeaker and a microphone of the slave computer to enter a standby state, then the second processor enters the standby state, and the second 2.4G module sets a timer to be interrupted by itself; when the timer is interrupted and the timing is finished, the second 2.4G module wakes up and scans a signaling channel autonomously, monitors whether the first 2.4G module of the host broadcasts a broadcast signal containing a connectable identifier within a second preset time period, if the broadcast signal containing the connectable identifier is not monitored, the second 2.4G module enters a standby state and sets the timer interrupt autonomously again, if the broadcast signal containing the connectable identifier is monitored, the second 2.4G module establishes air connection with the first 2.4G module of the host and exits the standby state, the second 2.4G module sends a wake-up pulse to a wake-up pin of the second processor, the slave wakes up the second processor, so that the automatic start-up and host connection work of the slave is realized when the host is started up and operated, and the slave automatically enters the standby state along with the host when the host is shut down/standby, the electric quantity of the battery is saved, and the slave is powered on by the battery, through a reasonable automatic dormancy and awakening strategy, the slave can continue to operate for a longer time under the condition of not influencing the use of a user.
Further, in another embodiment of the power consumption optimization method of the 2.4G wireless audio system of the present invention, after the second processor detects that the off duration is longer than the first preset duration, the power consumption optimization method further includes:
step A1, the second processor detects whether the slave is in a charging state;
the slave is internally provided with a battery for supplying power to each functional module and part of the slave, so that the second processor is additionally provided with a battery management module for the battery, and the second processor can detect whether the slave is in a charging state or not through the battery management module.
And step A2, if the slave is not in the charging state, executing the step that the second processor controls the second 2.4G module, the loudspeaker and the microphone of the slave to enter the standby state.
After the slave determines to be disconnected from the master for the first preset time, if the slave is not in the charging state, the slave uses the battery to work, and at this time, it is urgently needed to save the electric quantity for the slave, so that at this time, the second processor controls the second 2.4G module, the speaker and the microphone of the slave to enter the standby state, and continues to execute the subsequent steps of the step S30, the second 2.4G module sets the timer to interrupt itself, and the like.
Optionally, after the step of detecting whether the slave is in the charging state by the second processor, the method further includes:
step A3, if the slave is in the charging state, the second 2.4G module of the slave scans the signaling channel and monitors whether the first 2.4G module of the host broadcasts the broadcast signal containing the connectable identifier; if the broadcast signal which is broadcasted by the first 2.4G module of the host and contains the connectable identifier is monitored, the second 2.4G module of the slave and the first 2.4G module of the host establish air connection.
After the slave machine determines that the slave machine is disconnected with the host machine for a first preset time, if the slave machine is in a charging state, the slave machine works by using the charged electric quantity, the slave machine does not need to save the electric quantity at the moment, so that the slave machine has sufficient electric quantity to preferentially ensure the timely connection with the host machine at the moment, and the second 2.4G module of the slave machine continuously scans a signaling channel and monitors whether the first 2.4G module of the host machine broadcasts a broadcast signal containing a connectable identifier or not; if a broadcast signal which is broadcasted by the first 2.4G module of the host and contains the connectable identifier is monitored, the second 2.4G module of the slave and the first 2.4G module of the host establish air connection so as to ensure the timely connection between the slave and the host as much as possible.
In this embodiment, after the slave is disconnected from the master for a first preset time, if the slave is in a charging state, the slave has sufficient available electric quantity, at this time, the slave preferentially considers reconnection detection with the master, the slave normally operates, and the second 2.4G module scans a signaling channel; if the slave is in a non-charging state, the slave is powered by a battery, the available electric quantity is preferred, the slave takes the electric quantity saving priority, enters a standby state, and is interrupted and awakened by a timer to detect whether the host can be connected or not, so that the intelligent selection between the host reconnection priority and the slave electricity saving is realized according to different charging states of the slave, and the use experience of a user on the slave is not influenced as much as possible.
In addition, the power consumption optimization method of the present invention further comprises:
step a4, if the slave is switched from the charging state to the non-charging state, executing a step of detecting whether the disconnection duration of the second 2.4G module and the first 2.4G module of the master is greater than a first preset duration by the second processor of the slave. That is, after the slave is charged, when the slave is recovered to the uncharged state, the battery capacity of the general slave is relatively sufficient, and the user generally needs to use the slave, so that the slave is not directly standby like the uncharged state under the general use condition of the slave, but the connection state of the slave and the master is determined again by judging whether the disconnection duration of the disconnection between the second 2.4G module and the first 2.4G module of the master is greater than the first preset duration, and if the disconnection between the slave and the master is within the first preset duration, the related subsequent steps of the slave standby are performed, so that the cruising ability of the slave is further optimized, and the intelligent degree of the user using the slave is not influenced.
Further, in another embodiment of the power consumption optimization method of the 2.4G wireless audio system of the present invention, the power consumption optimization method further includes:
step B1, the second 2.4G module of the slave computer counts the continuous interruption times of the interruption timing end of the continuous occurrence timer;
and step B2, if the continuous interruption times is greater than the preset critical times, the second 2.4G module increases the timer interruption timing length so that the second 2.4G module sets the timer interruption based on the new timing length.
If the second 2.4G module of the slave counts that the continuous interruption frequency of the interruption timing of the timer is more than the preset critical frequency, the slave attempts to establish the wireless connection with the host continuously and fails for the preset critical frequency, the interruption of the slave and the host is probably not accidental wireless network connection failure or signal interruption, the master is shut down or the slave is not in the working range of the host with high probability, at the moment, in order to further improve the battery endurance capacity of the slave, the timer interruption of the second 2.4G module of the slave is not needed to be frequent, the second 2.4G module increases the timing duration of the timer interruption, increases the autonomous awakening time interval of the second 2.4G module of the slave, and reduces the autonomous awakening frequency of the second 2.4G module, because the slave computer is not successfully reconnected with the host computer for many times, the fact that a user does not actively intervene in wireless connection between the slave computer and the host computer is inferred, the user does not need to reconnect the slave computer and the host computer so urgently, and therefore the slave computer further improves the endurance time of the battery under the condition that the use of the user is not influenced.
In addition, an acceleration sensor electrically connected with the second 2.4G module is arranged in the slave computer;
after the step of counting the number of continuous interrupts of which the timer interrupt timing ends continuously occurs by the second 2.4G module of the slave, the method further includes:
step B3, if the continuous interruption times are larger than the preset maximum times, the second 2.4G module cancels the timer interruption, activates an acceleration sensor in the slave to detect the acceleration of the slave, and then the second 2.4G module enters a standby state;
and step B4, if the acceleration sensor detects that the acceleration of the slave computer is greater than the preset acceleration value, waking up the second 2.4G module, recovering the initial value of the timing duration interrupted by the timer, executing the step of scanning the signaling channel by the second 2.4G module, and monitoring whether the first 2.4G module of the host computer broadcasts the broadcast signal containing the connectable identifier within the second preset duration.
The preset maximum times are larger than the preset critical times, when the continuous interruption times are determined to be larger than the preset maximum times, the fact that the slave is disconnected from the host for a long time is indicated, and a user does not actively intervene in connection between the slave and the host, at the moment, the slave does not need to be automatically awakened based on timer interruption to reconnect the host, at the moment, the timer interruption is cancelled by the second 2.4G module of the slave, an acceleration sensor in the slave is activated to detect the acceleration of the slave, and then the second 2.4G module enters a standby state, namely only the acceleration sensor in the slave continues to work to monitor the motion state of the slave.
If the acceleration sensor detects that the acceleration of the slave is larger than the preset acceleration value, the motion state of the slave is changed violently, the slave is likely to be picked up and operated by a user, at the moment, the acceleration sensor of the slave wakes up the second 2.4G module, the timer interruption timing duration recovers the initial value, the second 2.4G module replies the timer interruption function, the second 2.4G module scans the signaling channel again, whether the first 2.4G module of the host broadcasts the broadcast signals containing the connectable identifier within the second preset duration is monitored, and if the host is started and the slave is within the working range of the host at the moment, the second 2.4G module of the slave and the first 2.4G module of the host establish aerial connection smoothly.
In this embodiment, after the continuous interruption is greater than the preset maximum number of times, it is determined that the reconnection requirement of the user on the slave and the host is low, in order to further reduce the power consumption of the slave, the second 2.4G module cancels the timer interruption, the second 2.4G module enters the standby state, and synchronously activates the acceleration sensor in the slave to detect the acceleration of the slave, the acceleration sensor with low power consumption is used to wake up the second 2.4G module at the timing when the acceleration of the slave is greater than the preset acceleration value, and the second 2.4G module is only woken up when the acceleration of the slave is greater than the preset acceleration value, so that the cruising ability of the slave is further improved.
Based on the above embodiments, the first preset time is longer than the timer interruption time, the timer interruption time is longer than the second preset time, for example, the first preset time is 30 seconds, the real-time is 5 seconds, and the second preset time is 100 microseconds, after the slave is disconnected from the host for 30 seconds, the second processor and the second 2.4G module of the slave enter a standby state, the speaker and the microphone of the slave are turned off, the second 2.4G module autonomously wakes up every 5 seconds based on the timer interruption, after waking up, the second 2.4G module determines whether the host broadcasts the broadcast information containing the connectable identifier within 100 microseconds, and if not, the second 2.4G module enters the standby state again, so that the cycle is repeated, and thus, the electric quantity of the slave battery is not excessively consumed, and the host state can also be detected in the first time.
