Furthermore, in the description of the present application, unless otherwise indicated, "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

One terminal device may have multiple operating systems, for example, one terminal device may include a first operating system and a second operating system, the operating systems operating by means of a processor. The first operating system may include an Android system, the second operating system may include an MCU system, or the first operating system may include an MCU system, and the second operating system may include an Android system, which is not limited herein.

In some embodiments, since the operating system of the terminal device includes a first operating system and a second operating system, the operating system currently used by the terminal device may be the first operating system or the second operating system, which is not limited herein. When the operating system currently used by the terminal device is the first operating system, the second operating system may be in a dormant state or may be in a closed state, and when the operating system currently used by the terminal device is the second operating system, the first operating system may be in a dormant state or may be in a closed state, which is not limited herein.

In some embodiments, the power consumption of the normal operation of the first operating system is higher than the power consumption of the normal operation of the second operating system, that is, the power consumption of the terminal device caused by the operation of the first operating system is higher than the power consumption of the terminal device caused by the operation of the second operating system under the same operation environment. Based on this, in this embodiment, the functional hardware may be mainly mounted on the second processor running the second operating system, that is, the functional hardware may be mainly controlled by the second system with smaller normal running power consumption, so as to reduce the power consumption of the terminal device. Wherein the functional hardware may include a screen, a vibration motor, a horn, a camera, etc., and the screen, the vibration motor, the horn, the camera, etc., may be primarily mounted on a second processor running a second operating system. In the terminal equipment, for an application needing to call a functional device to collect information, if the sensor is required to be started to collect information, a first operating system is required to send a starting instruction to a second operating system, and the second operating system controls the functional device which is being called by the application to start information collection based on the received starting instruction; if the function device finishes information acquisition, the first operating system is required to send a finishing instruction to the second operating system, and the second operating system controls the function device which is being called by the application to finish information acquisition based on the received finishing instruction.

However, if the application is abnormally finished in the running process, the first operating system does not send a finishing instruction to the second operating system, and the second operating system controls the function device which is being called by the application to finish information acquisition, so that the function device which is being called by the application can continue to perform information acquisition, the electric quantity of the terminal equipment is wasted, and the using time of the terminal equipment is influenced.

Referring to fig. 1, a system structure diagram of an information transmission method is provided in an embodiment of the present application. As shown in fig. 1, the information transmission method provided in the embodiment of the present application may be applied to a terminal device having a system structure shown in fig. 1, where the terminal device includes, but is not limited to, a mobile phone, a handheld device, a vehicle-mounted device, a personal computer, a notebook computer, an intelligent wearable device, and other terminal devices having multiple operating systems.

The terminal equipment comprises a first operating system and a second operating system, and the system structure shown in fig. 1 comprises the first operating system and the second operating system. In the first operating system, a keep-alive process and at least one target application may be included. The second operating system may include a task item corresponding to the second operating system, for example, an opening instruction corresponding to the functional device. Optionally, the power consumption of the terminal device for normally operating the first operating system is smaller than the power consumption of the terminal device for operating the second operating system.

The first operating system may be an android system, an IOS system, etc. running on the terminal device, and the second operating system may be a real-time operating system (Rea lTime Operating System, RTOS) running on the terminal device. The real-time operating system may also be WIN CE (Windows Embedded CE, WIN CE), winko system VxWorks, RT-Thread system, uCOS system (Micro-Controller Operating System Two), etc. The first operating system and the second operating system are communicated through a Dual-core communication module (Dual-Core Communication, DCC).

Referring to fig. 2, a flow chart of an information transmission method is provided in an embodiment of the present application. The terminal device is provided with a target application, and the method may include the following steps S101 to S102:

s101, the first operating system acquires information of abnormal ending operation of a target application, wherein the information of abnormal ending operation is used for indicating the abnormal ending operation of the target application;

it can be understood that the target application may be any application pre-installed in the terminal device, or may be a third party application installed by the user. The target application can call the functional device, wherein the functional device can be a sensor, a camera, a lens module and the like, and the functional device called by the target application can acquire information according to the requirement of the target application. For example, the target application may be a relaxation application, where the relaxation application is an application that allows a user to perform rhythmic breathing or meditation under video and audio guidance, and in the running process of the relaxation application, the heart rate detection sensor corresponding to the relaxation application collects information such as a heart rate and pressure of a human body, so that when the relaxation application ends, the collected information such as the heart rate and pressure of the human body is displayed on a display interface of the terminal device for the user to review.

If the target application is required to acquire the information acquired by the functional device, the first operating system does not directly call the functional device on the terminal equipment, the first operating system in the terminal equipment is required to send a starting instruction to the second operating system, and the second operating system controls the functional device required by/corresponding to the target application to start information acquisition based on the received starting instruction; if the functional device called by the target application is required to end information acquisition, the first operating system is required to send an end instruction to the second operating system, and the second operating system controls the functional device called by the target application to end information acquisition based on the received end instruction. The first operating system sends an instruction to the second operating system, and the second operating system controls the starting or ending of the called functional device required by the target application based on the received instruction.

For example, the target application may be a relaxation application and the functional device that the relaxation application is invoking may be a heart rate detection sensor. The relaxation application is an application running on a first operating system, when a user clicks an icon for starting to collect the heart rate of a human body in the relaxation application, the first operating system sends a starting instruction of a heart rate detection sensor corresponding to the relaxation application to a second operating system, and the second operating system controls the heart rate detection sensor corresponding to the relaxation application to start working when receiving the starting instruction. When a user clicks an icon for ending the acquisition of the heart rate of the human body in the relaxation application, the first operating system sends an ending instruction of the heart rate detection sensor corresponding to the relaxation application to the second operating system, and the second operating system controls the heart rate detection sensor corresponding to the relaxation application to stop working when receiving the ending instruction.

However, in the process of running the target application, abnormal ending operation may occur, at this time, the first operating system may not send an ending instruction corresponding to the loosening application to the second operating system, and the functional device being invoked by the loosening application may continuously collect information such as heart rate of a human body. The abnormal ending operation of the target application may be that the target application ends under the condition of non-user wish, for example, due to the phenomena of slow data loading, network interruption and the like caused by the too high temperature of the central processing unit of the terminal equipment, the target application is abnormally ended in the operation process.

In one embodiment, the first operating system continuously monitors the state of the target application, and when the target application abnormally ends running, the first operating system acquires a message that the target application abnormally ends running.

S102, the second operating system acquires a stop instruction, wherein the stop instruction is generated based on the abnormal ending operation information of the target application, and the stop instruction is used for indicating the second operating system to control the functional device which is being called by the target application to stop working.

After acquiring the abnormal ending operation information of the target application, the first operating system generates a stopping instruction corresponding to the target application based on the abnormal ending operation information of the target application, sends the stopping instruction to the second operating system, and controls the target application to stop working.

The function device called by the target application may be a sensor that needs to be called for starting (working) to realize the function of the target application, for example, the target application may be a relaxation application, in order to realize that the relaxation application displays information such as a human heart rate, a heart rate detection sensor is set on the terminal device, when the relaxation application needs to call the heart rate detection sensor, a first operating system sends a start instruction to a second operating system, and the second operating system can control the heart rate detection sensor corresponding to the relaxation application to start collecting the information such as the human heart rate based on the received start instruction.

It can be understood that, under the condition that the target application abnormally ends to run, the first operating system can acquire a message that the target application abnormally ends to run, generate a stop instruction corresponding to the target application based on the message that the target application abnormally ends to run, and send the stop instruction corresponding to the target application to the second operating system, and the second operating system controls the functional device being invoked by the target application to stop working based on the acquired stop instruction.

By adopting the embodiment, the first operating system obtains information of abnormal ending operation of the target application, where the information of abnormal ending operation is used to indicate the abnormal ending operation of the target application; the second operating system acquires a stop instruction, wherein the stop instruction is generated based on the abnormal ending operation information of the target application, and the stop instruction is used for indicating the second operating system to control the functional device which is being called by the target application to stop working. The problem of waste of electric quantity of the terminal equipment caused by continuous operation of the functional device which is being called by the target application when the target application abnormally finishes running can be avoided, and the effects of saving the power consumption of the terminal equipment and prolonging the service time of the terminal equipment are achieved.

Referring to fig. 4, a flowchart of an information transmission method is provided in an embodiment of the present application. The information transmission method is applied to a terminal device, the terminal device comprises a first operating system and a second operating system, a keep-alive process can be operated in the first operating system, in a state that a target application is opened, the target application can register a target Binder in the keep-alive process, and the information transmission method can comprise the following steps S201 to S203:

S201, in a state that the target application is started, the target application calls a Binder registration method of the keep-alive process to register a target Binder, and the target Binder corresponds to at least one target stop instruction;

optionally, in the state that the target application is opened, the target application invokes a Binder registration method of the keep-alive process to register a target Binder, the keep-alive process creates a target deshrifecient for the target Binder, binds the target Binder with the target deshrifecient, and the target deshrifecient corresponds to at least one target stop instruction.

It can be understood that the state that the target application is in the open state may be that the target application is controlled to be in the open state by clicking an open key corresponding to the target application on a display screen of the terminal device by a user.

The first operating system may run a keep-alive process, where the keep-alive process is a service for helping forwarding information, and the generation of the keep-alive process may be divided into two layers, where one layer is to improve the priority of the keep-alive process, so as to reduce the probability that the keep-alive process is accidentally killed, for example, monitor a screen locking event and an unlocking event of the terminal device, start an Activity of 1 pixel when the screen is locked, and destroy the Activity when the screen is unlocked. On the other hand, when abnormal ending operation occurs, the first operating system restarts the keep-alive process, for example, when abnormal ending operation occurs in the keep-alive process, the first operating system sends out response broadcast, and the corresponding broadcast monitor is registered in the Android management in a static mode, so that the keep-alive process can be pulled when a response event occurs, and the keep-alive process is in a survival state continuously. The keep-alive process can help to send messages when other applications abnormally end up running, and the functional devices which can be called by the applications abnormally end up running are controlled.

The method comprises the steps that a Binder registration method is included in a keep-alive process, the target application directly calls the Binder registration method in the keep-alive process to register a target Binder when the target application is in an opened state, the target application calls the Binder registration method once to register a target Binder, if the target application calls the Binder registration method for a plurality of times, a plurality of target binders can be registered, the keep-alive process creates a target deshrifecient for the target Binder while registering the target Binder, and the target Binder and the keep-alive process create the target deshrifecient for the Binder to bind.

The keep-alive process creates a target deathrecept for the target Binder and binds the target Binder with the target deathrecept, e.g., target application a may register a target Binder a in the keep-alive application while the keep-alive process creates a target deathrecept a for this target Binder a and binds target Binder a with target deathrecept a. If the target application calls the Binder registration method multiple times, multiple target Binders may be registered, for example, target application B calls the Binder registration method in the keep-alive process to register the first target Binder, create a corresponding deathreecientB-1 for Binder B-1, bind Binder B-1 with deathreecentB-1, target application may also continue to call the Binder registration method in the keep-alive process to register the second target Binder, create a corresponding deathreecentB-2 for Binder B-2, and bind Binder B-2 with deathreecentB-2.

For example, the target application may be a relax application, and in a state where the relax application is opened, the relax application calls a Binder registration method of the keep-alive process to register the target Binder, and at the same time, the keep-alive process creates a target desthrecient for the target Binder, and binds the target Binder with the target desthrecient.

The Binder is an inter-process communication mechanism, and mainly relates to 4 roles Client, server, service Manager and Binder drivers in a Binder framework, wherein Client, server and Service Manager operate in a user space, binder drivers operate in a kernel space, clients represent Client processes, and servers provide various services such as audio and video and the like for the Client processes. Service Manager is used to manage various system services. The Binder communication process can be divided into three steps, firstly, a process registers itself as a Service Manager through a Binder driver by using a BINDERSETCONTEXT_MGR command, and then, a Server registers a Binder (Binder entity in the Server) in the Service Manager through the Binder driver, which indicates that services can be provided externally. The Binder driver creates a reference to an entity by an entity node and a Service Manager in the kernel for the Binder, packages and transmits the name and the newly created reference to the Service Manager, the Service Manager fills the name and the newly created reference into a lookup table, and finally the Client obtains the reference to the Binder entity from the Service Manager with the help of the Binder driver by the name, and the communication with the Server process can be realized through the reference.

The Binder registration method includes information to be provided by the target application when registering, such as a registration name, parameters used for registering, a calling mechanism being a life monitoring mechanism, and information of a functional device called by the target application.

Optionally, the target desthreeceient created by the keep-alive process corresponds to a sended method, and the sended method includes at least one target stopping instruction, where one target desthreeceient corresponds to one sended method, and one sended method may include at least one target stopping instruction, where the at least one target stopping instruction is set corresponding to each functional device called by the target application. If there are two functional devices called by the target application, the target stop instructions may be two, and the two target stop instructions respectively correspond to the two functional devices called by the target application. For example, the target application may be a relaxation application, the functional device that the relaxation application is calling is an electrocardiographic detection sensor and a human body pressure detection sensor, if the relaxation application registers a target Binder, the target desthrecient corresponding to the target Binder may correspond to two target stop instructions, one may be for controlling the electrocardiographic detection sensor to stop working, and the other may be for controlling the human body pressure detection sensor to stop working.

After the target application registers the target Binder in the keep-alive process, the keep-alive process binds the death monitoring service for the target Binder corresponding to the target application, after the death monitoring service is bound, the first operating system can monitor the target application corresponding to the target Binder, if the abnormal end operation information of the target application is obtained, based on the death monitoring service, the first operating system indicates to which one or which one of the deathfeeceppients the abnormal end operation information of the target application is sent.

S202, the first operating system acquires information of abnormal ending operation of a target application, wherein the information of abnormal ending operation is used for indicating the abnormal ending operation of the target application;

when the abnormal ending operation of the target application occurs, the first operating system acquires information of the abnormal ending operation of the target application and sends the information of the abnormal ending operation to the kept alive process, and specifically, the first operating system sends the information of the abnormal ending operation of the target application to a target desthrecient bound with a target Binder, and triggers and executes a binding speed method corresponding to the target desthrecient.

S203, the second operating system acquires at least one target stopping instruction corresponding to the target Binder, the target stopping instruction is generated based on information of abnormal ending operation of the target application, and the target stopping instruction is used for indicating the second operating system to control the functional device which is being called by the target application to stop working.

And because the BinderDied method corresponding to the target desthrecasting is triggered, the keep-alive process sends at least one target stopping instruction corresponding to the target Binder to the second operating system, and the second operating system controls the functional device which is being called by the target application to stop working based on the target stopping instruction.

And the kept-alive process sends at least one target stopping instruction corresponding to a target desthrecasting bound with a target Binder to the second operating system, and the second operating system controls the functional devices corresponding to the target stopping instructions to stop working.

Because the information of the abnormal ending operation of the target application may include a name of the target application, an abnormal ending time, a functional device that the target application is calling, and the like, and the target application may register one or more target binders, when registering the plurality of target binders, the plurality of target binders bind with respective corresponding target desthrepepents, the first operating system may determine to which desthrepepent the information of the abnormal ending operation of the target application needs to be sent based on the information of the abnormal ending operation of the target application.

For example, the target application may be a relaxation application, the function device that the relaxation application is calling may be a heart rate detection sensor, taking the example that the relaxation application registers a target Binder in a keep-alive process, if the relaxation application abnormally ends running, the first operating system sends a message that the relaxation application abnormally ends running to a target deshrifecient that the relaxation application binds to the registered target Binder, triggers execution of a binderdiod method corresponding to the target deshrifecient bound to the target Binder, the binderdiod method includes an item label stop instruction, the content of the target stop instruction is that the electrocardiograph detection sensor that the relaxation application calls stops working, and sends an item label stop instruction in the binderdiod method to the second operating system in the keep-alive process, and the second operating system controls the electrocardiograph detection sensor corresponding to the target stop instruction to stop working.

If the number of the functional devices called by the target application is multiple, the binderDied method corresponding to the target desthrecient can contain multiple target stop instructions, and can trigger a part of target stop instructions or trigger all target stop instructions. For example, the target application may be a relaxation application, if the functional devices that can be invoked by the relaxation application are a heart rate detection sensor and a pressure detection sensor, but only the heart rate detection sensor is currently being invoked, only the target stop instruction corresponding to the heart rate detection sensor may be sent, the target stop instruction corresponding to the pressure detection sensor is not sent, and all the target stop instructions may be triggered, and because all the stop instructions include the target stop instruction corresponding to the heart rate detection sensor, the heart rate detection sensor that is being invoked by the relaxation application may be stopped.

It can be appreciated that, because the relax application may call the registration method in the keep-alive process one or more times, one target Binder may be registered by calling the registration method once, if the relax application calls the registration method in the keep-alive process multiple times, multiple target binders may be registered, when the relax application registers multiple target binders, the keep-alive process binds one target desthreshould for each target Binder, at this time, if the first operating system obtains a message that the relax application has abnormally ended, the first operating system may send the message that the relax application has abnormally ended to all target desthreshould corresponding to the relax application, and trigger execution of the BinderDied method corresponding to all target desthreshould corresponding to the relax application. For each target desthrecasting, the target stopping instruction corresponding to the functional device being invoked may be selectively sent to the second operating system, or the target stopping instructions corresponding to all functional devices that the loosening application may invoke may be sent to the second operating system. And after the second operating system receives the target stopping instruction, controlling the functional device which is being called by the loosening application to stop working.

Referring to fig. 8, a flowchart of an information transmission method is provided in an embodiment of the present application. The information transmission method is applied to a terminal device, the terminal device includes a first operating system and a second operating system, the first operating system includes a keep-alive process and a target application, in this embodiment, a registered target Binder and a corresponding target deshrifecient may be unbinding or deregistering in the process, and the information transmission method may include the following steps S301 to S304:

s301, in a state that the target application is started, the target application calls a Binder registration method of the keep-alive process to register a target Binder, and the target Binder corresponds to at least one target stop instruction;

please refer to S201, which is not described herein.

S302, the first operating system acquires information of abnormal ending operation of a target application, wherein the information of abnormal ending operation is used for indicating the abnormal ending operation of the target application;

it can be understood that, in a state where the target application normally ends running, the first operating system ends monitoring of the running state of the target application.

In one embodiment, in a state that the target application normally ends running, the target application calls a Binder cancellation method of the keep-alive process to cancel the target Binder, and/or the keep-alive process unbinds the target Binder from the target desthrecient.

The target application calls the Binder logout method of the keep-alive process to logout the target Binder based on the instruction of the user to end the target application, and the target application can avoid excessive number of Binders in the keep-alive process and occupy the memory of the keep-alive process under the state that the target application normally ends operation.

The Binder logout method includes information to be provided by the target application when registering, such as a registration name of the target application, parameters for logout, a calling mechanism being a life monitoring mechanism, and information of a functional device called by the target application.

Please refer to S202, which is not described herein.

S303, the second operating system acquires at least one target stopping instruction corresponding to the target Binder, the target stopping instruction is generated based on information of abnormal ending operation of the target application, and the target stopping instruction is used for indicating the second operating system to control the functional device which is being called by the target application to stop working.

Please refer to S203, which is not described herein.

In one embodiment, only the abnormal ending running message of the target application may be sent to a preset number of target destemeceients in the target destemeceients corresponding to the target application, so as to trigger and execute the binderDied method corresponding to the preset number of target destemeceients.

S304, the keep-alive process logs off the target Binder, and/or unbinds the target Binder and the target desthrecient.

After the second operating system controls the functional devices corresponding to the target stop instructions to stop working, the keep-alive process logs off the target Binder, so that the situation that the number of Binders in the keep-alive process is excessive and the memory of the keep-alive process is occupied can be avoided.

In one embodiment, in the keep-alive process, a Binder list is maintained, where the Binder list includes keys corresponding to applications in which binders are registered and values corresponding to keys corresponding to applications, where each Value is composed of a Binder registered by each application and each deshrifecient corresponding to each Binder. The Key corresponding to each application may be a parameter used for registration when registering the Binder for each application.

As shown in fig. 6, the Key corresponding to the application E in the Binder list is E, the Value corresponding to the Key is a Binder E registered by the application E, and the desthreepiente corresponding to the Binder E, the Key corresponding to the application F is F, and the Value corresponding to the Key is a Binder F registered by the application F, and the desthreepient F corresponding to the Binder F.

The unbinding the target Binder and the target deshrieceient by the keep-alive process may be that the target application is triggered to execute an unbinding action on the target Binder and the target deshrieceient simultaneously based on an instruction of ending the target application by a user or after the second operating system controls the functional device corresponding to each target stop instruction to stop working, and at least one Value corresponding to at least one Key corresponding to the target application is searched in a Binder list based on at least one Key corresponding to the target application, so as to obtain at least one target Binder corresponding to the target application and at least one deshrieceient corresponding to the target Binder, and unbinding the at least one target Binder and the at least one deshrieceient corresponding to the target Binder.

As shown in fig. 7, the target application is target E, and the corresponding Value is searched in the Binder list based on the Key corresponding to the target application E, and the Binder E and the deathreceptent E corresponding to the Binder E are unbinding after the corresponding Value is searched as the Binder E registered by the application E and the deathreceptent E corresponding to the Binder E.

It can be appreciated that the keep-alive process can log off the target Binder, so that excessive numbers of binders and desthreeceptins in the Binder list can be avoided, and the memory of the keep-alive process is occupied. Unbinding the target Binder and the target desthrecasting can avoid re-registering the target Binder when the target application is restarted next time, and save the time of target Binder registration.
