Description
Technical Field
The invention relates to the technical field of portable intelligent electronic equipment energy management, in particular to an energy balance use management method of intelligent electronic equipment based on game theory.
Background
With the rapid development of wireless communication technology, smart phones and smart wearable devices have also been developed in rapid motion, and in recent years, smart wearable devices have been gradually applied in the fields of biology, health, medical treatment, education, sports, and the like. Different kinds of portable intelligent electronic devices have specific functions and simultaneously generate a plurality of using functions which are overlapped in a crossing way, for example: the telephone call function of the smart phone watch and the call function of the smart phone are overlapped in a crossing way; the simple information transceiving function of the smart phone watch and the short message function of the smart phone are overlapped. In the future, smart wearable devices may also generate many cross-overlapping usage functions between each other. The intelligent wearable equipment provides great convenience for use for people in a smart carrying mode and a detection function. However, smart wearable devices are limited by portability, the devices are often small, and a battery system for providing a system power supply is generally lacking in a large enough space, and under the existing battery technology condition, a battery with too small volume cannot achieve high capacity, which means that the smart wearable devices cannot have a large-capacity battery like a smart phone, and the electric energy capacity of the battery is generally about one fourth of that of the smart phone. And because the continuous increase of the functional units leads to continuous increase of power consumption of the intelligent wearable equipment system, the service time of the intelligent wearable equipment can be shortened, and further the user experience is reduced. For how to allow the electric energy of various intelligent wearable devices and smart phones to cooperatively manage and work for a longer time at the same time, the prior art cannot meet the requirement.
Disclosure of Invention
Gambling theory is the theory of studying the rational decision behavior of interdependent, interacting decision bodies and the balanced outcome of these decisions. The selection of connectable intelligent electronic devices is essentially a resource allocation way of energy balance, each device hopes to use for a longer time, and benefits are maximized, which is a typical non-cooperative game model, and we introduce the model into an energy balance management strategy. The invention provides an energy balance use management method of intelligent electronic equipment, which utilizes the idea of game theory to realize the optimal scheduling of equipment energy use, balances the power consumption of intelligent mobile phones and intelligent wearable equipment and realizes the scientific and reasonable energy management of the intelligent electronic equipment.
The invention provides an energy balance use management method of intelligent electronic equipment, which is applied to the intelligent electronic equipment with a Bluetooth communication function.
Intelligent wearable device includes: the energy balance use management method between the smart phone watch, the smart bracelet, the smart glasses and the like and the smart phone can be briefly expressed as follows: the intelligent wearable device and the intelligent mobile phone are in the range of the maximum communication radius of a Bluetooth network of the intelligent mobile phone, and communication connection is established between the intelligent mobile phone and the intelligent wearable device through the Bluetooth network; the game energy balance management system running on the smart phone can monitor the electric quantity state, the current busy state and the electric quantity change rate of each intelligent electronic device in the smart phone Bluetooth network within a previous fixed period of time; judging the event type when an event request is received, and calling a game energy balance management method to automatically select the intelligent electronic equipment with proper energy and function to finish the response of the event when the event belongs to the event which can be executed on a plurality of intelligent electronic equipment; when the intelligent wearable equipment is out of the range of the maximum communication radius of the intelligent mobile phone Bluetooth network, the independent working state of each intelligent electronic equipment is restored; and when the intelligent wearable equipment reenters the maximum communication radius range of the Bluetooth network of the intelligent mobile phone and the received event belongs to an event which can be executed on a plurality of intelligent electronic equipment, restoring and calling a game energy balance management method, and selecting the optimal intelligent electronic equipment to respond to the event request.
The invention provides an energy balance use management method of intelligent electronic equipment, which comprises the following steps:
step one: define a certain functional use of the smart wearable device and the smart phone as an event, including but not limited to: dialing, answering a call, receiving and sending a short message, positioning, requesting data and watching a video; formalizing an Event may formalize the Event as a five-tuple-described entity, namely:
Event＝＜ID,A/B,D,S,E＞ (1)
An identifier of the Event, which has uniqueness;
A/B: the Event type is divided into an Event A which can be executed on a plurality of intelligent electronic devices and an Event B which can only be executed on the device which receives the Event;
d: an original receiving device of the event;
S: the state set of the Event, the behavior in Event, is the overall process of describing the transition from one state to another state during the Event;
E, energy consumed by executing the use event;
Thus, a group of events can be defined, the relation and interaction rule between the events can be established, and the process of jointly completing the task can be embodied;
Step two: the intelligent mobile phone is used as a main node of the Bluetooth communication network, searches the intelligent electronic equipment which is in the Bluetooth network communication range and has rights to use, and forms a Bluetooth communication network with the intelligent electronic equipment; when at least one intelligent electronic device is not searched in the Bluetooth network, each intelligent electronic device keeps an independent working state, and the intelligent mobile phone keeps the Bluetooth searching state of the step; when at least one intelligent electronic device is found to be in the Bluetooth network, entering a step III;
Step three: the intelligent wearable equipment and the intelligent mobile phone which are in normal working states in the Bluetooth network communication range wait for triggering the event, and the intelligent wearable equipment and the intelligent mobile phone comprise: triggering commands such as dialing, answering a call, receiving and sending a short message, positioning, requesting data, watching video and the like;
Step four: when any Event trigger occurs, the smart phone receives the Event trigger information of the intelligent electronic device with the Event request, substitutes the Event trigger information into the Event array defined in the step one, and judges the type of the Event used. For the event triggered, when Namely, the Event belongs to a type B Event which can only be executed on the equipment which initially receives the Event, the intelligent electronic equipment which initially receives the Event is selected to execute the Event, the intelligent mobile phone sends an instruction to the equipment, and the step six is skipped; when/>I.e. the Event belongs to an a-type Event executable on at least 2 intelligent electronic devices in the bluetooth network, then step five is entered;
step five: the smart phone acquires all remaining standby time t i (i=1, 2 … n) of the smart wearable device and the smart phone within the range of the maximum communication radius H of the smart phone Bluetooth network communication, the current busy and idle state of the smart wearable device and the smart phone, and the electric quantity change rate of the smart wearable device and the smart phone within a fixed period of time before the smart wearable device and the smart phone; designing a benefit function; invoking a game energy balance management method running on a smart phone, selecting an intelligent electronic device with the largest profit function from all devices which are within the maximum radius H of the Bluetooth network communication of the smart phone and can execute the event to execute the event, and sending an instruction to the selected intelligent electronic device by the smart phone; the necessary communication between the execution device finally selected by the event and the event initial receiving device is borne by Bluetooth communication;
The setting of the previous fixed time follows the following rule:
when the residual electric quantity of the intelligent electronic equipment is more than 60%, setting the previous fixed time to be 10 minutes; when the residual electric quantity of the intelligent electronic equipment is smaller than or equal to 60% and larger than 30%, setting the previous fixed time to be 5 minutes; and when the residual electric quantity of the intelligent electronic equipment is less than or equal to 30%, setting the previous fixed time to be 2 minutes.
Assuming that the electricity consumed by the intelligent wearable equipment and the intelligent mobile phone in unit time is w and the running time is t, the electricity consumption of the intelligent wearable equipment and the intelligent mobile phone in the unit time is
W＝w*t (2)
From knowledge in physics, the electric power (so-called electric quantity) is calculated as
W＝U*I*T (3)
Wherein U is a voltage value, I is a current value, and T is a running time. Since the voltage value U is generally constant in a device, the parameter U can be regarded as a constant, and the value can be expressed by the current and the time, so that the rest stand-by time of the device is
ti＝Wi/Ii (4)
Wherein W i is the residual capacity of the device, and I i is the current of the device;
In gaming, each connectable device is called a "participant", and each participant can select a complete course of action that is practically feasible, and can be selectively connected or disconnected, i.e., a policy set. The participant may select a single policy from a set of possible policies. The interaction between the participants is manifested in that each participant affects the outcome after all participants have selected their strategy. Each participant may evaluate its selected policy outcome by a utility function. Under normal circumstances, the standard form of gaming is given by Γ (N, S, { P i }) which includes three elements:
Participant set N: the set of participants in a game can be represented as n= {1,2, … N }, where N is the number of participants, here the number of connectable devices.
Policy set S: the policy set for participant i is denoted S i. If there are k alternative strategies, thenAbbreviated as S i＝{s1,s2,…,sk, the policy space s= { S 1,S2…,Sn }. Here, the policy of the connectable device is S i = { connect, disconnect }, s= (S i,s-i) represents a policy combination, where S i is the policy of the participant i, and S -i represents the policies of n-1 other participants than the participant i.
Participant i's benefit function P i：Pi represents the benefit of the ith participant under the policy combination (s i,s-i). We design a benefit function according to the energy balance management principle:
where l i(pi,p-i) represents connectivity of the device, l i(pi,p-i) =1 represents that the wearable intelligent electronic device and the handset are in a connection range, and when 0, it indicates that the wearable intelligent electronic device and the handset cannot be connected. t i is the current remaining standby time of device i, Indicating the level of difference in the remaining power of each device, n being the number of connectable devices. S i represents the busy state of the current device, S i =0 represents that the current device is in use, and S i =1 represents that the current device is in the idle state. /(I)The power consumption speed in a fixed time t period before the device, namely the power reduction amount in unit time, W i is the current residual power of the device i, W i-before is the residual power of the device i before the fixed time t period, and the larger the power consumption speed is, the smaller the probability of the device being selected is. Alpha, beta, lambda and mu are weight functions, are all positive numbers, and determine the influence of parameters on the benefit function. According to the weight, the equipment with more residual electric quantity is preferentially selected, and then the influence on the equipment selection is comprehensively considered according to the current busy state of the equipment, the electric quantity consumption speed in a fixed period of time before the equipment and the energy difference of the whole equipment.
From the above benefit functions we can get the potential functions of the game model:
If the connection policy of device i is changed from p i to q i, the difference in the benefit functions is:
And the difference of the potential functions is:
let us let Then there is
From the above formula (9) we can get sgn (Δp i) =sgn (Δq), Δq and Δp i symbols are identical, so this is an ordinal potential function, according to theoretical studies of ordinal potential functions, there must be a nash equalization for the model, Q in this state is the largest, i.e. under the policy s= { S 1,S2…,Sn } that makes the whole profit function the largest, the device in the connected state under this policy is selected as the optimal intelligent electronic device according to the connection situation of each device, for example: s= { disconnect, connect, disconnect }, namely select the 2 nd equipment to connect, the benefit is the largest under this condition, accord with our energy balance design requirement, help the energy balance management of the whole equipment in the network;
According to the result of the profit function, selecting intelligent electronic equipment which enables the profit function to be maximum from all equipment which is within the communication maximum radius H of the Bluetooth network of the smart phone and can execute the event to execute the using event;
Step six: executing, by the selected intelligent electronic device, the triggered event based on the judgment of the smart phone and the transmitted instruction; when the event belongs to the type B, after the event response is completed, entering a low-energy consumption management mode, and returning to the step two;
Step seven: after the Event response is completed, the smart phone continuously detects the Event request and the residual electric quantity state of the smart electronic device within the maximum communication radius H of the smart phone Bluetooth network; when the triggering of the Event is not detected within a certain time, the intelligent electronic equipment exits the game energy balance management mode and enters a low-energy consumption management mode, and the second step is returned; when the trigger of the Event is detected within a certain time later, returning to the step four;
The setting of the certain time thereafter follows the following rules:
When the electric quantity of the smart phone is less than 25%, and no trigger of an Event is detected within the next 5 seconds, the smart wearable device and the smart phone within the range of the maximum communication radius H of the Bluetooth network of the smart phone exit from the game energy balance management mode, enter into the low-energy management mode, and then return to the step two; when the trigger of the Event of use is detected within the next 5 seconds, jumping to the fourth step; when the electric quantity of the smart phone is in the range of 25% -50%, and no trigger of the Event is detected within the next 15 seconds, the smart wearable device and the smart phone within the range of the maximum communication radius H of the Bluetooth network of the smart phone exit from the game energy balance management mode, enter into the low-energy consumption management mode, and then return to the step two; when the use Event trigger is detected within the next 15 seconds, jumping to the fourth step; when the electric quantity of the smart phone is greater than 50%, and no trigger of the Event is detected within the next 40 seconds, the smart wearable devices and the smart phones within the range of the maximum communication radius H of the Bluetooth network of the smart phone exit from the game energy balance management mode, enter into the low-energy management mode, and then return to the step two; when a usage Event trigger is detected within the next 40 seconds, the process jumps to step four.
According to the invention, on the premise that the total electric quantity of each intelligent electronic device is unchanged, the using mechanism of the residual electric quantity of the intelligent wearable device and the intelligent mobile phone is cooperatively optimized through the game theory algorithm, and the energy consumption of each intelligent electronic device can be balanced and the task allocation is optimized through optimizing the connection of the intelligent electronic devices, so that the existing energy of the intelligent electronic device is utilized to the greatest extent, the normal use time of the intelligent electronic device is prolonged, and the user experience is improved.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
With the continuous development of computers and embedded technologies, various types of portable intelligent electronic devices are presented, and besides smart phones and palm computers, there are many intelligent wearable devices, including smart phone watches, smart bracelets, smart jewelry, smart glasses, and the like.
In general, smart wearable devices may include, but are not limited to, the following functions: the intelligent watch is used for carrying out telephone conversations at any time, real-time physical health detection, real-time positioning, listening to music through voice and actions by means of intelligent glasses, watching video, adding schedules, map navigation, shooting, video conversation, answering calls and the like. Because the volume restriction, can not carry the battery of high electric quantity generally, under current battery technical condition, the battery of too little volume can't accomplish high capacity, and its battery electric quantity can only be about one fourth of smart mobile phone battery electric quantity generally, along with the continuous increase of frequency of use and function, leads to the continuous increase of the power consumption rate of intelligent wearable equipment system, can shorten the live time of intelligent wearable equipment, and then has reduced user experience. How to ensure a sufficient effective use time becomes a significant problem. The invention needs to provide a method for achieving collaborative optimization management of electric quantity of various intelligent wearable devices and intelligent mobile phones and enabling the intelligent wearable devices and the intelligent mobile phones to work for a longer time as much as possible.
In the following embodiments, for convenience of description, only a smart phone watch, a smart bracelet and smart glasses are taken as examples, and the present invention is not limited to the smart wearable device.
The invention provides an energy balance use management method of intelligent electronic equipment. As shown in fig. 1, the system comprises a smart phone, a smart phone watch, a smart bracelet and smart glasses. The intelligent mobile phone and the intelligent wearable equipment are provided with Bluetooth communication functions, and can be interconnected through a Bluetooth communication network for data interaction. The smart phone is used as a main node of the Bluetooth communication network, and the maximum communication radius H of the Bluetooth network of the smart phone is the maximum communication radius of the Bluetooth network. When the distance H i,j between the intelligent wearable device and the smart phone is larger than H, normal Bluetooth communication cannot be performed between the intelligent wearable device and the smart phone. When the distance H i,j between the intelligent wearable device and the intelligent mobile phone is smaller than or equal to H, normal Bluetooth communication can be performed between the intelligent wearable device and the intelligent mobile phone; the intelligent wearable equipment and the intelligent mobile phone in the normal working state in the Bluetooth network communication range are used as objects of the energy balance use management method of the intelligent electronic equipment.
As shown in fig. 2, the invention provides an energy balance use management method of an intelligent electronic device, which comprises the following steps:
step one: define a certain functional use of the smart wearable device and the smart phone as an event, including but not limited to: dialing telephone, answering call, receiving and sending short message, positioning, requesting data, watching video and the like; formalizing an Event may formalize the Event as a five-tuple-described entity, namely:
Event＝＜ID,A/B,D,S,E＞ (1)
An identifier of the Event, which has uniqueness;
A/B: the Event type is divided into an Event A which can be executed on a plurality of intelligent electronic devices and an Event B which can only be executed on the device which receives the Event;
d: an original receiving device of the event;
S: the state set of the Event, the behavior in Event, is the overall process of describing the transition from one state to another state during the Event;
E, energy consumed by executing the use event;
Thus, a group of events can be defined, the relation and interaction rule between the events can be established, and the process of jointly completing the task can be embodied;
Step two: the intelligent mobile phone is used as a main node of the Bluetooth communication network, searches the intelligent electronic equipment which is in the Bluetooth network communication range and has rights to use, and forms a Bluetooth communication network with the intelligent electronic equipment; if at least one intelligent electronic device is not searched in the Bluetooth network, each intelligent electronic device keeps an independent working state, and the intelligent mobile phone keeps the Bluetooth searching state of the step; when at least one intelligent electronic device is found to be in the Bluetooth network, entering a step III;
Step three: the intelligent wearable equipment and the intelligent mobile phone which are in normal working states in the Bluetooth network communication range wait for triggering the event, and the intelligent wearable equipment and the intelligent mobile phone comprise: triggering commands such as dialing, answering a call, receiving and sending a short message, positioning, requesting data, watching video and the like;
Step four: when any Event trigger occurs, the smart phone receives the Event trigger information of the intelligent electronic device with the Event request, substitutes the Event trigger information into the Event array defined in the step one, and judges the type of the Event used. For the event triggered, when Namely, the Event belongs to a type B Event which can only be executed on the equipment which initially receives the Event, the intelligent electronic equipment which initially receives the Event is selected to execute the Event, the intelligent mobile phone sends an instruction to the equipment, and the step six is skipped; when/>I.e. the Event belongs to an a-type Event executable on at least 2 intelligent electronic devices in the bluetooth network, then step five is entered;
step five: the smart phone acquires all remaining standby time t i (i=1, 2 … n) of the smart wearable device and the smart phone within the range of the maximum communication radius H of the smart phone Bluetooth network communication, the current busy and idle state of the smart wearable device and the smart phone, and the electric quantity change rate of the smart wearable device and the smart phone within a fixed period of time before the smart wearable device and the smart phone; designing a benefit function; invoking a game energy balance management method running on a smart phone, selecting an intelligent electronic device with the largest profit function from all devices which are within the maximum radius H of the Bluetooth network communication of the smart phone and can execute the event to execute the event, and sending an instruction to the selected intelligent electronic device by the smart phone; the necessary communication between the execution device finally selected by the event and the event initial receiving device is borne by Bluetooth communication;
The setting of the previous fixed time follows the following rule:
when the residual electric quantity of the intelligent electronic equipment is more than 60%, setting the previous fixed time to be 10 minutes; when the residual electric quantity of the intelligent electronic equipment is smaller than or equal to 60% and larger than 30%, setting the previous fixed time to be 5 minutes; and when the residual electric quantity of the intelligent electronic equipment is less than or equal to 30%, setting the previous fixed time to be 2 minutes.
Assuming that the electricity consumed by the intelligent wearable equipment and the intelligent mobile phone in unit time is w and the running time is t, the electricity consumption of the intelligent wearable equipment and the intelligent mobile phone in the unit time is
W＝w*t (2)
From knowledge in physics, the electric power (so-called electric quantity) is calculated as
W＝U*I*T (3)
Wherein U is a voltage value, I is a current value, and T is a running time. Since the voltage value U is generally constant in a device, the parameter U can be regarded as a constant, and the value can be expressed by the current and the time, so that the rest stand-by time of the device is
ti＝Wi/Ii (4)
Wherein W i is the residual capacity of the device, and I i is the current of the device;
In gaming, each connectable device is called a "participant", and each participant can select a complete course of action that is practically feasible, and can be selectively connected or disconnected, i.e., a policy set. The participant may select a single policy from a set of possible policies. The interaction between the participants is manifested in that each participant affects the outcome after all participants have selected their strategy. Each participant may evaluate its selected policy outcome by a utility function. Under normal circumstances, the standard form of gaming is given by Γ (N, S, { P i }) which includes three elements:
Participant set N: the set of participants in a game can be represented as n= {1,2, … N }, where N is the number of participants, here the number of connectable devices.
Policy set S: the policy set for participant i is denoted S i. If there are k alternative strategies, thenAbbreviated as S i＝{s1,s2,…,sk, the policy space s= { S 1,S2…,Sn }. Here, the policy of the connectable device is S i = { connect, disconnect }, s= (S i,s-i) represents a policy combination, where S i is the policy of the participant i, and S -i represents the policies of n-1 other participants than the participant i.
Participant i's benefit function P i：Pi represents the benefit of the ith participant under the policy combination (s i,s-i). We design a benefit function according to the energy balance management principle:
where l i(pi,p-i) represents connectivity of the device, l i(pi,p-i) =1 represents that the wearable intelligent electronic device and the handset are in a connection range, and when 0, it indicates that the wearable intelligent electronic device and the handset cannot be connected. t i is the current remaining standby time of device i, Indicating the level of difference in the remaining power of each device, n being the number of connectable devices. S i represents the busy state of the current device, S i =0 represents that the current device is in use, and S i =1 represents that the current device is in the idle state. /(I)The power consumption speed in a fixed time t period before the device, namely the power reduction amount in unit time, W i is the current residual power of the device i, W i-before is the residual power of the device i before the fixed time t period, and the larger the power consumption speed is, the smaller the probability of the device being selected is. Alpha, beta, lambda and mu are weight functions, are all positive numbers, and determine the influence of parameters on the benefit function. According to the weight, the equipment with more residual electric quantity is preferentially selected, and then the influence on the equipment selection is comprehensively considered according to the current busy state of the equipment, the electric quantity consumption speed in a fixed period of time before the equipment and the energy difference of the whole equipment.
From the above benefit functions we can get the potential functions of the game model:
If the connection policy of device i is changed from p i to q i, the difference in the benefit functions is:
And the difference of the potential functions is:
let us let Then there is
From the above formula (9) we can get sgn (Δp i) =sgn (Δq), Δq and Δp i symbols are identical, so this is an ordinal potential function, according to theoretical studies of ordinal potential functions, there must be a nash equalization for the model, Q in this state is the largest, i.e. under the policy s= { S 1,S2…,Sn } that makes the whole profit function the largest, the device in the connected state under this policy is selected as the optimal intelligent electronic device according to the connection situation of each device, for example: s= { disconnect, connect, disconnect }, namely select the 2 nd equipment to connect, the benefit is the largest under this condition, accord with our energy balance design requirement, help the energy balance management of the whole equipment in the network;
