Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted terminal technology, and in particular to a platform-based power management method and system based on a built-in vehicle-mounted terminal. Background Art

[0002] At present, mobile Internet has become very popular. Various APPs allow mobile phones to have more functions. The functions of onboard cars are increasing. Many car manufacturers have launched the function of controlling vehicles through mobile phones. T-box (Telematics Box, the intelligent terminal of the Internet of Vehicles system) is a communication technology that is currently used more frequently. For example, using mobile phones to control vehicles ensures that the vehicle body status can be displayed on the mobile phone in real time and accurately. Most of the existing T-boxes communicate with vehicles based on the TCP protocol. Some use mature communication frameworks such as MQTT or Socket and other communication technologies to perform different business functions through communication data interaction, thereby meeting the use needs of vehicle-mounted software.

[0003] Since most vehicles currently do not have the sleep-fast start function, after the vehicle is used, the on-board terminal automatically shuts down after the screen is off for a few minutes, and restarts when the vehicle is used again, which affects the startup speed. Now more and more high-end vehicles use sleep-fast start technology, which uses extremely low power consumption when the vehicle is not in use, and quickly enters the operation interface when the vehicle is used again, without restarting. However, most T-box technologies are not compatible with the sleep-fast start scenario, and cannot cope with the effective and fast communication between the T-box and the mobile phone in this scenario. The system needs to be redesigned to ensure that the T-box can communicate quickly with the mobile phone in the sleep-fast start scenario. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present application provides a platform-based power management method and system based on a built-in vehicle-mounted terminal, which can keep the vehicle body, T-box and server consistent according to the power status, thereby processing text messages or network communication data according to different power status, and achieving accurate and low-latency user experience.

[0005] In a first aspect, the present application provides a platform-based power management method based on a built-in vehicle terminal, the vehicle terminal includes a data communication center, a service management center and a power management service, and the method includes the following steps:

[0006] When the power signal of the vehicle body is in a normal state, the power management state of the vehicle terminal is set to a normal state, and the data communication center reports to the server to perform network communication;

[0007] When the power signal of the vehicle body is in the screen-off state, the countdown task is performed according to the set first time based on the power management service; wherein, if during the countdown to zero, the power signal of the vehicle body is received to change from the screen-off state to the screen-on state, the countdown task is cleared; if during the countdown to zero, the power signal of the vehicle body is not received to change from the screen-off state to the screen-on state, the power management state of the vehicle terminal is set to the silent state, and the network connection with the server is disconnected;

[0008] When the power management state of the vehicle terminal is in silent state, when the vehicle machine SMS service is received based on the service management center, the power management state of the vehicle terminal is set to normal state, and the data communication center reports to the service end, performs network communication, and executes the vehicle machine SMS service and the countdown task;

[0009] When the power signal of the vehicle body and the power management status of the vehicle terminal are both in sleep mode, and based on the service management center receiving the vehicle-machine SMS service, the vehicle is awakened, the power signal of the vehicle body is turned to silent mode, and the power management status of the vehicle-machine terminal is set to normal mode, and the data communication center reports to the service end to conduct network communication, and executes the vehicle-machine SMS service and the countdown task.

[0013] In response to the vehicle control request sent by the server, the corresponding data is taken out from the data cache pool and sent to the server; if a confirmation character is received from the server, the corresponding data is cleared; if no confirmation character is received from the server, the data is resent according to the set interval mechanism.

[0014] In a possible implementation, setting the power management state of the vehicle terminal to a silent state and disconnecting the network connection from the server includes the following steps:

[0015] After the power management state of the vehicle terminal is set to silent state, a sleep message is sent to the data notification center;

[0016] After receiving the sleep information, the data notification center stops receiving the vehicle control request sent by the server, and starts sending the data in the data buffer pool. After the sending is completed, the network connection with the server is disconnected.

[0033] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0034] In view of the technical problems raised by the background technology, the present application provides a platform-based power management method and system based on a built-in vehicle-mounted terminal, which can keep the vehicle body, T-box and server consistent according to the power status, thereby processing text messages or network communication data according to different power status, and achieving accurate and low-latency user experience.

[0035] In one embodiment, see the attached specification Figure 1 The present application provides a platform-based power management method based on a built-in vehicle terminal, wherein the vehicle terminal includes a data communication center, a service management center, and a power management service, and the method includes the following steps:

[0036] S1. When the power signal of the vehicle body is in a normal state, the power management state of the vehicle terminal is set to a normal state, and the data communication center reports to the server to perform network communication;

[0037] S2. When the power signal of the vehicle body is in the screen-off state, the countdown task is performed according to the set first time based on the power management service; wherein, if during the countdown to zero, the power signal of the vehicle body is received to change from the screen-off state to the screen-on state, the countdown task is cleared; if during the countdown to zero, the power signal of the vehicle body is not received to change from the screen-off state to the screen-on state, the power management state of the vehicle terminal is set to the silent state, and the network connection with the server is disconnected;

[0038] S3, when the power management state of the vehicle terminal is in silent state, based on the service management center receiving the vehicle machine SMS service, the power management state of the vehicle terminal is set to normal state, and based on the data communication center, it is reported to the service end, network communication is performed, and the vehicle machine SMS service and the countdown task are executed;

[0039] S4. When the power signal of the vehicle body and the power management status of the vehicle terminal are both in sleep mode, and based on the service management center receiving the vehicle-machine SMS service, the vehicle is awakened, the power signal of the vehicle body is turned to silent mode, and the power management status of the vehicle-machine terminal is set to normal mode. The data communication center reports to the service end, performs network communication, and executes the vehicle-machine SMS service and the countdown task.

[0040] In order to clearly understand the technical solution of the embodiment of the present application, the built-in vehicle terminal used in the present application can be described first. Figure 2 In addition to the data communication center, service management center, and power management service, the vehicle terminal also includes a vehicle data bus and a task module. Specifically, in this application, the data communication center is used for data communication interaction between the vehicle terminal and the external network, which is generally the network of major car manufacturers;

[0041] The service management center is a service management center for each business module with a built-in T-box, which is used to receive data from external communications. In one embodiment, the service management center contains multiple services. The definition of a service is a complete functional module. A system is composed of multiple services, such as SMS service, vehicle body communication service, remote operation service, vehicle safety service, etc. The services are uniformly managed by a ServiceManager. Each service has a service name, and the name of each service will not be repeated. At the same time, the service has a corresponding instance. The ServiceManager stores each service. The services can communicate with each other. By obtaining the service name through the ServiceManager, the instance of the service can be obtained. With the service instance, the function in the service can be called. The function of the service is responsible for the management of the task module and the business processing of the corresponding service. For example, the SMS service is responsible for receiving SMS during the vehicle's dormant stage. The vehicle has extremely low power consumption and does not have the ability to provide external communication. If the mobile phone sends a vehicle control command at this time, such as remote engine start, the command cannot reach the vehicle through the network, but sends data to the vehicle through the SMS function. The SMS service is responsible for parsing and distributing the SMS, and each service is responsible for processing the corresponding business;

[0042] The task module is a specific software function implementation module, which is a subdivision function of the service. The task module defines the task ServiceID of the service to which it belongs. Each ServiceID is pre-defined with the car manufacturer. Each task sends data containing the ServiceID. The car manufacturer server determines the specific task function based on the ServiceID. Similarly, the data sent by the server to the vehicle also contains the ServiceID. The vehicle terminal executes the corresponding function based on the ServiceID. The task module is the smallest functional execution unit;

[0043] The vehicle data bus directly communicates with the vehicle bus to receive and send vehicle data. Due to limited communication network reasons, if it takes a long time to obtain data from the vehicle each time, when there is a lot of interactive data, it is very easy for the system to be disconnected or blocked. Therefore, a monitoring mechanism is adopted in this application. First, PropertyID is defined. PropertyID represents a vehicle body signal provided by the vehicle service to T-box for use. When the signal value corresponding to PropertyID changes, the vehicle actively notifies T-box, and the T-box local service performs a cache Map processing to cache the value corresponding to each PropertyID. When it is needed, there is no need to go to the vehicle to obtain it. The corresponding signal value can be quickly obtained from the local cache, which greatly improves the efficiency of data acquisition.

[0044] The power management service is responsible for processing the T-box power management logic according to the power status of the vehicle body and reporting the power status to the service end, that is, executing the above steps S1 to S4.

[0045] In step S1, the vehicle is powered on for the first time, the program starts, and the power signal of the vehicle body is in the normal state. When the vehicle terminal receives the power signal of the vehicle body through the vehicle data bus, it sets the power management state of the vehicle terminal to the normal state, establishes a communication connection with the server, and reports to the server. Figure 3 The power management state of the vehicle terminal is set to a normal state, and the data communication center reports to the server to perform network communication, including the following steps:

[0046] S101, establishing a communication connection with a server based on a data communication center; wherein, if the connection fails, retrying is performed; if the connection is successful, reporting to the server that the power management state of the vehicle terminal is set to a normal state, so that after the server receives the power management state of the vehicle terminal being set to a normal state, it conducts network communication with the data communication center in accordance with the agreed communication method;

[0047] S102, responding to the vehicle control request sent by the server, taking out the corresponding data from the data cache pool and sending it to the server; wherein, if a confirmation character returned by the server is received, clearing the corresponding data; if no confirmation character returned by the server is received, resending according to the set interval mechanism.

[0048] In step S101, the data communication center establishes a communication connection in accordance with the communication method agreed upon with each vehicle manufacturer. Currently common communication methods include Socket, MQTT and other TCP-based communication methods. If the connection fails, the center will retry. Only after the connection is successful will the center report the power management status of the vehicle terminal to be set to normal. After receiving the power management status of the vehicle terminal set to normal, the server will subsequently control the vehicle through network communication.

[0049] In step S102, the data communication center is responsible for the data interaction between the vehicle terminal and the server. For the data processing, the data will be placed in the data buffer pool List first, and the data will be interacted with the server one by one from the data buffer pool List. If the data is sent successfully, the server will respond with an ACK (Acknowledgment, confirmation character). After receiving the ACK, the data communication center will clear the corresponding data; if the sending fails, it will be resent to the List and sent again after an interval of 5 seconds. For example, after receiving the data, the server will verify and process the data. If the data is received successfully and meets the requirements, the server will immediately respond with an ACK to the data communication center. After receiving the ACK, the data center of the data communication center determines the corresponding successfully sent data according to the information in the ACK. Then, the data is cleared from the data buffer pool List to release the storage space and prepare for subsequent data storage and processing; if the data communication center does not receive the ACK from the server within a reasonable time after sending the data, or the received ACK indicates that the data transmission fails, then the data communication center will put the data back into the data buffer pool List. In order to avoid excessive pressure on the system caused by frequent retries, a mechanism for sending again after an interval of 5 seconds is set. During this 5-second interval, the data communication center can continue to process other data, or perform some system maintenance and optimization operations. When the 5-second time has passed, the data communication center will take out the data from the data buffer pool List again and send it, repeating the above process until the data is sent successfully and ACK is received.

[0050] By continuously retrying to send failed data, it ensures that the data can be successfully transmitted to the server, greatly improving the reliability of the data. This is particularly important in the network communication interaction between the vehicle terminal and the vehicle manufacturer group, because vehicle-related data is often related to the safe operation and management of the vehicle. Even in the case of network instability or a brief failure on the server, it can ensure that the data will not be lost, but will continue to be transmitted when conditions permit. And the mechanism of sending again at an interval of 5 seconds avoids too frequent retries and reduces the occupation of network resources and system processing capabilities. If there is no such interval mechanism, a large amount of duplicate data may be sent continuously in a short period of time, causing network congestion and system performance degradation.

[0051] It should be noted that in this application, a data threshold is set based on the size of the data cache pool; the amount of data in the data cache pool is obtained in real time; if the amount of data is greater than the set data threshold, data caching is stopped. For example, when the size of the data cache pool List is greater than 1,000 data, the excess data is no longer received. This is to protect the system from filling up the memory due to excessive data.

[0052] In step S2, when the vehicle enters the screen-off state and the vehicle terminal obtains the current vehicle body in the screen-off state through the vehicle data bus, the power management service starts the countdown task according to the set first time. For example, the first time is set to 2 minutes. If the vehicle turns on the screen again within two minutes and is obtained by the vehicle data bus, the countdown task is cleared; if the vehicle does not turn on the screen again and is not obtained by the vehicle data bus within 2 minutes, the power management state of the vehicle terminal is set to the silent state, and a sleep message is sent to the data notification center. After the data notification center receives the sleep message, it stops receiving the vehicle control request sent by the server, and starts sending the data in the data cache pool. After the sending is completed, the network connection with the server is disconnected. This ensures that data will not be missed and ensures data consistency and integrity.

[0053] Among them, after the vehicle screen is turned off for a second time, the power signal of the vehicle body turns into a dormant state, and in the dormant state, the vehicle has no communication capability; when the second time is greater than the first time, and the power management state of the vehicle terminal is in a silent state for the second time, it turns into a dormant state. For example, if the second time is 3 minutes, then between 2 minutes and 3 minutes when the vehicle screen is turned off, the power management state of the vehicle terminal is in a silent state, and after 3 minutes, the power signal of the vehicle body and the power management state of the vehicle terminal are both in a dormant state.

[0054] In step S3, when the power management state of the vehicle terminal is in the silent state, the mobile phone controls the vehicle by sending text messages to the vehicle terminal. First, the received vehicle-mounted text message service is cached in the data cache pool based on the service management center, and then the power management state of the vehicle terminal is switched to the normal state. The communication starts to connect. After the communication connection is successful, the text message is parsed and executed, and the power management state of the vehicle terminal is reported to the server at the same time. After the vehicle control command is executed, the timing is restarted for 2 minutes, and the logical processing of step S2 is repeated.

[0055] In step S4, when the power signal of the vehicle body and the power management status of the vehicle terminal are both in the dormant state, if the mobile phone APP controls the vehicle, a text message is first sent to the vehicle terminal, and the vehicle terminal wakes up the vehicle to change the power signal of the vehicle body from the dormant state to the silent Slient state. At the same time, the text message is first cached in the data cache pool List and not executed. When the power signal of the vehicle body is obtained through the vehicle data bus to change from the dormant state to the silent Slient state, the power management state of the vehicle terminal is set to the normal state, and the communication connection is started, the text message control is parsed and executed, and the power management state of the vehicle terminal is reported to be set to the normal state to the server. After the vehicle control command is executed, the timing is restarted for 2 minutes, and the logical processing of step S2 is repeated.

[0056] The platform-based power management method based on the built-in vehicle terminal provided by this application can keep the vehicle body status, the power management status of the vehicle terminal and the car factory server consistent according to the power status for the current vehicle sleep and quick start scenario, so as to process SMS or network communication data according to different power statuses, and at the same time, when disconnecting the data communication center, the cached data needs to be sent completely to ensure that the server obtains the latest result of the current vehicle, so that the user can accurately know the status of his vehicle. Prevent data loss, and be able to adapt to the vehicle's quick start and timely control of the vehicle, so as to achieve an accurate and low-latency user experience.
