Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a low power consumption wireless control method applied to a transmitting end according to an embodiment of the present invention. The present embodiment is applicable to a case where the transmitting end provides a wireless control signal to the receiving end to control the receiving end to perform a control task, and can be integrated into the transmitter provided in the embodiments of the present invention. As shown in fig. 1, the method specifically comprises the following steps:
and S11, receiving the key pressing action of the user and generating a key pressing signal.
Specifically, the transmitting terminal may include a button for receiving a key action of a user, and may generate a key signal when the key action is received. When a user clicks the button, the button generates a key signal to trigger the transmitting terminal to start working.
S12, triggering the transmitting terminal to send a control signal lasting for a first time length to the receiving terminal according to the key signal, so that the receiving terminal awakened once every second time length receives the control signal; wherein the second duration is less than the first duration.
After the key signal is generated, the transmitting terminal can be triggered to transmit the control signal lasting for the first time length to the receiving terminal according to the key signal, and the receiving terminal can be better ensured to receive the control signal by lasting the control signal for the first time length. Meanwhile, the receiving end can be awakened once every second time interval to receive the control signal, so that the receiving state does not need to be kept constantly to reduce the consumption required by the receiving end, and the receiving end can execute the receiving operation at least once in the process of sending the control signal with the first time duration by the transmitting end by setting the second time duration to be less than the first time duration, namely setting the awakening frequency of the receiving end to be higher than the sending frequency of the transmitting end, so that the receiving end can be ensured to receive the control signal sent by the transmitting end every time.
On the basis of the above technical solution, optionally, before triggering the transmitting end to send the control signal lasting for the first duration to the receiving end according to the key signal, the method further includes: triggering a transmitting terminal to start up according to the key signal; correspondingly, after the transmitting terminal is triggered to transmit the control signal lasting for the first duration to the receiving terminal according to the key signal, the method further comprises the following steps: and controlling the transmitting terminal to be powered off. Specifically, the transmitting terminal can be in a power-off state at ordinary times, when a user clicks a button of the transmitting terminal, a key signal can be generated to trigger the transmitting terminal to be powered on, a control signal lasting for a first time length is sent to the receiving terminal after the transmitting terminal is powered on, and accordingly the transmitting terminal can be directly powered off after the signal is sent. The transmitting terminal can be kept in a power-off state for most of the time and is powered on only when the transmitting terminal needs to work, so that the consumption required by the transmitting terminal can be further reduced. By reducing the consumption of the transmitting end and the receiving end, a button battery and the like can be used for supplying power very conveniently, and the service life of the power transmission device can be maintained for half a year.
The low-power wireless control method provided by the embodiment can be applied to the vehicle compliment, and for the convenience of a user, the transmitting end of the compliment is usually arranged on a center console at the front part in the vehicle, and the receiving end of the compliment is usually arranged on a rear windshield of the vehicle. The installation of the compliment can be conveniently completed in a wireless control mode, the power consumption of the compliment method is extremely low, power can be supplied through a button battery and the like, the compliment device is not required to be connected with an original circuit in a vehicle, the compliment method is very convenient to use, and the power supply is not required to be frequently replaced. In the use, when a vehicle enters at the intersection, one party can actively allow the other party to enter, at the moment, a preceding driver can press a button of the transmitting end of the praise device, and the praise lamp at the receiving end behind the vehicle can be turned on for a period of time, so that the following driver can see the praise given by the preceding driver, and good driving habits can be further promoted. Specifically, by applying the low-power-consumption wireless control method provided by the embodiment of the invention, the transmitting end of the approver can be normally in a power-off state, when a user clicks a button of the transmitting end of the approver, the transmitting end of the approver is triggered to be powered on, and is powered off after a approve signal lasting for a first time is sent to the corresponding receiving end of the approver, and the receiving end of the approver is awakened once every second time interval to detect whether the approve signal exists, if so, the approver lamp at the receiving end of the approver is lightened, and the approver lamp can be continuously lightened for a third time so as to be conveniently seen by a driver of a rear vehicle.
On the basis of the above technical solution, optionally, after receiving a key action of a user and generating a key signal, before triggering the transmitting terminal to send a control signal lasting for a first duration to the receiving terminal according to the key signal, the method further includes: determining a time interval between the key signal and a previous key signal; a first duration is determined based on the time interval. Specifically, the longer the second duration is, the more time the receiving end has to sleep, the lower the overall average consumption is, but the longer the response time is, the less frequent wakeup may not quickly detect the control signal sent by the transmitting end, thereby generating a little delay and reducing the user experience. Conversely, the shorter the second duration is, the higher the wake-up frequency of the receiving end becomes, the higher the overall average consumption becomes, but the control signal sent by the transmitting end can be quickly detected, so that the response is quick, the delay is reduced, and the user experience is improved. Meanwhile, the first duration needs to be longer than the second duration, so the size of the first duration may need to be changed along with the change of the second duration, and the increase of the first duration may also result in the increase of the power consumption of the transmitting end. Therefore, it is necessary to balance each factor to obtain the better first time duration and the better second time duration, in this embodiment, it can be specifically realized by an algorithm for dynamically adjusting the time duration, that is, at the transmitting end, after each generation of the key signal, the first time duration can be determined according to the time interval between the key signal and the previous key signal, and the generation time of the key signal can be recorded. According to the time interval, the use frequency of the user can be determined, and then the first duration can be adjusted according to the requirement of the user so as to improve the experience of the user.
Further optionally, the first duration increases with increasing time interval. Specifically, when the user clicks the button of the transmitting terminal for multiple times in a short time, the next click with high probability can be performed in a short time, at the moment, the first duration can be reduced, meanwhile, the second duration can be reduced according to the first duration, so that the response efficiency is improved, when the user does not click the button of the transmitting terminal for a long time, the time interval of the next click with high probability can be longer, at the moment, the first duration can be increased, and meanwhile, the second duration can be increased according to the first duration, so that the power consumption of the receiving terminal is reduced. Optionally, the first duration increases exponentially with the time interval, so that when the time interval is smaller, the first duration changes slowly, and when the time interval is larger, the first duration changes quickly, so as to further improve the user experience. Further optionally, determining the first duration according to the time interval includes:
wherein a represents a first time duration, b represents a second time duration, e represents a natural base number, and h represents a time interval. By using the formula, various factors can be well balanced under different use frequencies of users, so that the user experience is improved to the maximum extent and the power consumption is reduced.
Further optionally, the second duration is between a preset minimum threshold and a preset maximum threshold. In other words, in the process of dynamically adjusting the second duration, it is ensured that the second duration is not less than the preset minimum threshold and does not exceed the preset maximum threshold, so that the second duration is not decreased or increased without limit, normal operation between the transmitter and the receiver is ensured, and consumption is not excessively increased. Optionally, the preset minimum threshold may be 1-2 seconds, and the preset maximum threshold may be 2-8 seconds. Preferably, the preset minimum threshold is 1 second, the preset maximum threshold is 6 seconds, and according to the above formula, when the time interval is 0, that is, when the user continuously clicks, the first time length is 2 seconds, the second time length is 1 second, when the time interval exceeds 2.75 seconds, the first time length is 7 seconds, and the second time length is 6 seconds, that is, the longest sleep time length of the receiving end does not exceed 6 seconds.
According to the technical scheme provided by the embodiment of the invention, firstly, a transmitting terminal receives a key action of a user and generates a key signal, then the transmitting terminal triggers the transmitting terminal to send a control signal lasting for a first time length to a receiving terminal according to the key signal, the receiving terminal enters a dormant state after being started and is awakened once every second time length to detect the control signal sent by the transmitting terminal, and when the receiving terminal detects the control signal, a control task corresponding to the control signal is executed. The second duration is set to be less than the first duration, so that the receiving end can be ensured to receive the control signal from the transmitting end, the receiving end does not need to keep a receiving state all the time, and the receiving end can be in a dormant standby state most of the time, thereby realizing the wireless control function with ultra-low power consumption. The method can be further applied to the vehicle praise device, so that the effect of showing thank you to a driver of a backward vehicle with simplicity, convenience and low power consumption can be realized.

and S21, controlling the receiving end to start and enter a dormant state.
Specifically, the receiving end can be started when the receiving end starts to be used, and then the receiving end enters a dormant state, and the power consumption of the receiving end in the dormant state is extremely low.

S22, waking up the receiving end every second time length to detect that the transmitting end triggers the control signal which lasts for the first time length when receiving the key pressing action of the user and generating the key pressing signal; wherein the second duration is less than the first duration.
After the receiving end is started and enters a dormant state, the receiving end can be awakened once by the timer every second time interval so that the receiving end can detect whether the control signal sent by the transmitting end exists or not. Meanwhile, the transmitting terminal can trigger to send a control signal lasting for a first time length to the receiving terminal according to the key signal when receiving the key action of the user and generating the key signal. By setting the second duration to be less than the first duration, that is, setting the wakeup frequency of the receiving end to be higher than the sending frequency of the transmitting end, the receiving end can execute the receiving operation at least once in the process of sending the control signal of the first duration by the transmitting end, so that the receiving end can receive the control signal sent by the transmitting end every time, and the receiving end does not need to keep the receiving state all the time, thereby reducing the consumption required by the receiving end. Optionally, after the receiving end is awakened each time, the receiving end keeps the awakening state for the fourth time period, and can continuously detect the control signal for the fourth time period, so as to improve the accuracy of the detection result.
And S23, when the control signal is detected, executing the control task corresponding to the control signal.
Specifically, when the receiving end detects the control signal, the receiving end may execute a control task corresponding to the control signal, which may be determined according to an application scenario of the method. For example, when the low-power wireless control method provided by this embodiment is applied to a vehicle approval device, the control signal is an approval signal, and when the approval device receiving end detects an approval signal sent by the approval device transmitting end, a task of approving a light at the highlight approval device receiving end may be executed, and the approval light may be continuously turned on for a third duration.
On the basis of the above technical solution, optionally, before waking up the receiving end every second duration to detect that the transmitting end receives the key action of the user and generates the key signal and trigger the transmitted control signal lasting the first duration, the method further includes: determining a time interval between the key signal and a previous key signal; the second duration is determined based on the time interval.
Further optionally, the second duration increases with increasing time interval. Further optionally, the second duration increases exponentially with the time interval. Further optionally, determining the second duration according to the time interval includes:
wherein b represents the second time duration, e represents a natural base number, h represents a time interval, and a represents the first time duration. Further optionally, the second duration is between a preset minimum threshold and a preset maximum threshold.
The above description may refer to the description of the corresponding contents in the first embodiment, and will not be repeated here.
