Fig. 2 shows a schematic implementation flow chart of a method for synchronizing information according to an embodiment of the present invention.
Referring to fig. 2, the method for synchronizing information according to the embodiment of the present invention is applied to a first electronic device, where the first electronic device includes a first processing unit and a second processing unit, the first processing unit runs a first operating system, the second processing unit runs a second operating system, and the working energy consumption of the first processing unit is smaller than the working energy consumption of the second processing unit, and at least includes the following operation flows: operation 201, the first processing unit performs selection of a positioning system and stores the selected positioning system information; operation 202, when determining that the first trigger condition for performing the synchronization of the positioning system information is met, the first processing unit synchronizes the stored positioning system information to the second processing unit; in operation 203, the second processing unit performs processing related to positioning according to the obtained positioning system information.
In an embodiment of the invention, the first electronic device is a wearable electronic device, the first processing unit is a micro control unit MCU, and the second processing unit is a central processing unit CPU.
In one embodiment of the present invention, the first processing unit runs a first operating system that is an RTOS (Real Time Operating System, real-time operating system), and the second processing unit runs a second operating system that is an intelligent operating system, for example: and (5) an Android system. The working energy consumption of MCU to run RTOS is smaller than the working energy consumption of CPU to run Android.
For example, the first electronic device is a smart watch, and includes an MCU running an RTOS and a CPU running an Android system.
In the process of illustrating each operation step, in order to more intuitively illustrate the scheme of the embodiment of the present invention, the first electronic device is taken as the smart watch, the first processing unit is taken as the MCU running the RTOS, and the second processing unit is taken as the CPU running the Android system as an example. Of course, the first electronic device in the embodiment of the invention is not limited to the smart watch, the first processing unit is not limited to the MCU, the second processing unit is not limited to the CPU, the first operating system is not limited to the RTOS, and the second operating system is not limited to the Android.
In operation 201, the first processing unit performs selection of a positioning system and saves the selected positioning system information.
In one embodiment of the invention, the first processing unit supports communication connections with a plurality of positioning systems, and the first processing unit performs the selection of the positioning systems in the following manner: the first processing unit obtains signal intensities of a plurality of positioning systems, and selects a positioning system with highest signal intensity from the signal intensities; and determining the selected positioning system as a corresponding positioning system of the first processing unit for executing the positioning function, and controlling a positioning module corresponding to the selected positioning system in the first processing unit to be in a working state, and controlling a positioning module corresponding to a non-selected positioning system in the first processing unit to be in a non-working state.
For example, the positioning system may comprise: BDS (BeiDou Navigation Satellite System, beidou satellite navigation system), GPS (Global Positioning System ), GLONASS (GLONASS positioning system), galileo satellite navigation system. The MCU obtains signal strengths of the corresponding plurality of positioning systems, and selects a positioning system with the highest signal strength from the signal strengths, for example: and if the BDS in a certain area is the positioning system with the highest signal intensity in the plurality of positioning systems, the MCU determines the corresponding positioning system which utilizes the BDS to execute the positioning function, controls the positioning module corresponding to the BDS in the MCU to be in a working state, and simultaneously controls the positioning modules corresponding to the GPS, GLONASS and Galileo satellite navigation systems in the MCU to be adjusted to be in a non-working state.
The MCU selects one positioning system from the plurality of positioning systems, and is mainly used for adjusting the positioning modules corresponding to other unselected positioning systems in the MCU to a non-working state so as to save energy consumption and prolong the endurance time of the intelligent watch. Connection delay caused by frequent switching of the MCU among a plurality of positioning systems can also be avoided, because under normal conditions, a positioning module running on a smart watch, a mobile phone, a vehicle navigation system and the like needs a long time to be connected with a satellite positioning system, and the time can be intuitively perceived by people, for example: for a period of about 1 minute.
In one embodiment of the present invention, the positioning module running in the first processing unit selects a positioning system with the highest signal strength from the plurality of positioning systems through a star finding process in a working state, and stores positioning system information of the selected positioning system.
In an embodiment of the present invention, after selecting the positioning system with the highest intensity, comparing the signal intensity corresponding to the positioning system with the highest intensity with a first threshold; when the signal intensity corresponding to the positioning system with the highest intensity is larger than or equal to a first threshold value, determining the positioning system with the highest intensity as the selected positioning system; and when the signal intensity corresponding to the positioning system with the highest intensity is smaller than a first threshold value, determining the second electronic equipment with the positioning function, which is connected with the first electronic equipment, as the selected positioning system.
In an embodiment of the present invention, the second electronic device is an intelligent terminal, for example: a mobile phone, a tablet computer, etc.
In the process of illustrating each operation step, in order to intuitively illustrate the solution of the embodiment of the present invention, the solution of the embodiment of the present invention is explained by taking the second electronic device as an intelligent terminal as an example.
For example, the first threshold may be a signal strength set according to an actual requirement, where the signal strength can be set to ensure that a positioning module running in the MCU can perform relatively fast communication with the positioning system. And after the MCU selects a positioning system BDS with highest signal intensity in positioning systems such as BDS, GPS, GLONASS, galileo satellite navigation systems and the like. And comparing the signal intensity corresponding to the BDS with a first threshold value, and if the signal intensity corresponding to the BDS is greater than the first threshold value, indicating that effective communication can be performed between the positioning module running in the MCU and the BDS, and ensuring that the positioning module running in the MCU normally acquires positioning data from a positioning system. At this time, the BDS is determined as the selected bit system.
If the signal intensity corresponding to the BDS is lower than the first threshold value, the fact that effective communication can not be carried out between the running positioning module in the MCU and the positioning systems can not be ensured, and the positioning module running in the MCU can not normally acquire positioning data from the positioning systems. At this time, the MCU may be selected to communicate with the intelligent terminal, from which satellite data is synchronized. For example: the MCU may communicate with the intelligent terminal via BLE (Bluetooth Low Energy ).
In an embodiment of the present invention, when the signal strength corresponding to the positioning system with the highest strength is smaller than the first threshold, and the signal strength between the second electronic device and the positioning system in communication connection with the second electronic device is also smaller than the first threshold, it is indicated that the first processing unit cannot normally acquire the positioning information of the positioning system through the second electronic device. At this point, the first processing unit may re-perform selected operations of the positioning system.
For example, the signal strength between the positioning module and the positioning systems running in the MCU is smaller than the first threshold, at this time, the MCU tries to connect with the intelligent terminal through BLE, and synchronizes positioning information from the intelligent terminal. However, at this time, the signal strength between the intelligent terminal and the positioning system BDS that the intelligent terminal is in communication connection with is also smaller than the first threshold, and the MCU may try to connect with a plurality of positioning systems again. Until one of the positioning systems is successfully connected.
In an embodiment of the present invention, the following specific operations are adopted to determine the second electronic device with the positioning function, connected to the first electronic device, as the selected positioning system: and when the signal intensity is greater than or equal to a first threshold value, determining the second electronic equipment with the positioning function connected with the first electronic equipment as a selected positioning system of the first processing unit.
For example, the positioning system with the highest signal intensity among the positioning systems such as MCU and BDS, GPS, GLONASS, galileo satellite positioning system is BDS. The signal intensity between the MCU and the BDS is X, and X is smaller than a first threshold value. And the signal intensity of communication between MCU and intelligent terminal is Y, can communicate through BLE between MCU and the intelligent terminal. And if Y is greater than the first threshold, the MCU can be selected to communicate with the intelligent terminal, and satellite data is synchronized from the intelligent terminal.
In an embodiment of the present invention, after determining the selected positioning system as the corresponding positioning system for which the first processing unit is used to perform the positioning function, signal strengths of the first processing unit and the corresponding positioning system currently used to perform the positioning function are also obtained, and the obtained signal strengths are compared with a second threshold; when the obtained signal strength is smaller than a second threshold value, the first processing unit is re-obtained to obtain the current signal strength of each positioning system, and the positioning system with the highest current signal strength is selected from the current signal strength; when the corresponding signal intensity of the positioning system with the highest current signal intensity is larger than or equal to a first threshold value, determining the positioning system with the highest current signal intensity as a new selected positioning system; if the new selected positioning system and the positioning system currently used for executing the positioning function are not the same positioning system, switching the positioning system used for executing the positioning function into the new selected system; wherein the second threshold is the same as or different from the first threshold.
For example, the MCU determines the positioning system with the highest signal strength from among the positioning systems as the BDS when the MCU previously performed the selected operation of the positioning system. The signal intensity between the MCU and the BDS is X, and X is larger than a first threshold value. After the BDS is selected as the corresponding positioning system for executing the positioning function by the current first processing unit, the MCU will again acquire the current signal strength Y of the communication between the BDS of the selected positioning system and the MCU, so as to confirm that the current signal strength of the communication between the BDS of the selected positioning system and the MCU can still ensure the normal communication between the MCU and the BDS. Specifically, the second threshold may be set to a minimum signal strength that ensures normal communication between the positioning module of the first processing unit and the positioning system, and if between the positioning module of the first processing unit and the positioning system, the first processing unit cannot normally acquire positioning data from the positioning system.
In operation 202, upon determining that the first trigger condition for performing positioning system information synchronization is met, the first processing unit synchronizes the saved positioning system information to the second processing unit.
In an embodiment of the present invention, the first triggering condition may be at least one of the following: the second processing unit is started to enter a working state; the first processing unit obtains a positioning data synchronization instruction sent by the second processing unit; the second processing unit starts an application related to positioning.
For example, because the intelligent operating system running based on the CPU is in a working state with higher energy consumption, in the embodiment of the present invention, the general application program in the first electronic device only needs to operate based on the RTOS system running by the MCU. And the RTOS system running based on the MCU and the intelligent operating system running based on the CPU respectively and independently store the positioning data of the RTOS system and the intelligent operating system. In order to ensure that the intelligent operating system running based on the CPU can quickly start or quickly start the positioning function, when the CPU enters the working state from the off state or the CPU enters the working state from the sleep state, for example: pressing a power key, clicking a smart watch display device, entering an intelligent operating system from a system switching setting of an RTOS system, etc., the MCU synchronizes the positioning system information stored in operation 201 to the CPU.
The intelligent operating system running based on the CPU may also request synchronous positioning data from the MCU side when the positioning function needs to be started, for example: the keys are opened through positioning functions, including virtual keys and physical keys. Or triggering the MCU to send the stored positioning system information to the CPU when an application program requiring positioning data in the CPU is started. For example: navigation or map applications running in the CPU, and the like.
In one embodiment of the present invention, the positioning system information includes a positioning system selected by the MCU, for example: BDS, GPS, GLONASS, galileo satellite positioning system. Therefore, when the CPU enters a working state or starts a positioning function, the CPU can directly communicate with a determined selected positioning system according to positioning system information acquired from the MCU, and the problems that operations such as satellite finding are repeatedly executed to determine which positioning system is selected to generate higher energy consumption, positioning function starting delay is caused and the like are avoided.
In an embodiment of the present invention, the positioning system information may further include parameters GGA and UTC obtained in the ephemeris process, where GGA is positioning data of a positioning system, and has a standard data specification. For example: GPGGA, <1>, <2>, <3>, <4>, <5>, <6>, <7>, <8>, <9>, M, <10>, M, <11>, <12> ×xx < CR > < LF >, wherein: GPGGA: a start guide and statement format description (this statement is GPS positioning data);
the <1> field is used to describe UTC time, in the format of hhmms.
The <2> field is used to describe the latitude in ddmm.mmmm (the first bit is zero will also be transmitted);
the <3> field is used to describe the latitude hemisphere, N or S (north latitude or south latitude);
the <4> field is used to describe longitude in dddmm.mmmm (first bit zero will also be transmitted);
the <5> field is used to describe longitude hemisphere, E or W (east or west longitude)
The <6> field is used to describe a positioning quality indication, 0 = positioning invalid, 1 = positioning valid;
the <7> field is used to describe the number of satellites used, from 00 to 12 (the first zero will also be transmitted)
The <8> field is used to describe level accuracy, 0.5 to 99.9
The <9> field is used to describe the altitude of the antenna from sea level, -9999.9 to 9999.9M refers to unit meters
The <10> field is used to describe the ground level height, -9999.9 to 9999.9M refers to unit meters
The <11> field is used to describe the differential GPS data deadline (RTCMSC-104), the number of seconds that the RTCM is last to transmit
The <12> field is used to describe the differential reference base station number, from 0000 to 1023 (the first 0 will also be transmitted).
The sea level height and the ground level height in the <9>, <10> fields are in meters.
UTC (Coordinated Universal Time ), also known as universal time, international coordinated time. Due to the different abbreviations for English (CUT) and French (TUC), UTC is abbreviated as a compromise. The representation of data elements and exchange formats-information exchange-date and time using CNS 7648 is called world universal time. UTC time is in hhmmss (time minutes seconds) format.
Therefore, the CPU can use satellite-to-ephemeris data acquired by the MCU synchronized with the MCU, so that an intelligent operation system running based on the CPU can realize quick positioning, and on the basis of effectively shortening TTFF (Time to First Fix, first positioning time) time and realizing quick starting of the CPU, communication time for acquiring current positioning data by communication with satellites in a positioning system is effectively reduced, and user experience is further improved. For example: the current position can be located quickly.
In an embodiment of the present invention, the positioning system information may further include location information and time stamp information of the first electronic device within a certain period of time.
In operation 203, the second processing unit performs positioning-related processing according to the obtained positioning system information.
In one embodiment of the present invention, the positioning system information includes a positioning system selected by the MCU, and the second processing unit performs a positioning operation according to the obtained positioning system information. Therefore, when entering a working state or starting a positioning function, the CPU can directly communicate with a determined selected positioning system according to positioning system information acquired from the MCU to acquire information such as the current position and the like, so that the problems that the repeated operations such as star finding are performed to determine which positioning system is selected to generate higher energy consumption, the starting delay of the positioning function is brought and the like are avoided.
In an embodiment of the present invention, the positioning system information may further include parameters GGA and UTC obtained during the ephemeris process. And the second processing unit realizes quick positioning according to the obtained positioning system information.
In an embodiment of the present invention, the positioning system information may further include location information and time stamp information of the first electronic device within a certain period of time. The second processing unit may perform processing of the positioning system information according to the acquired positioning system information.
For example, after the intelligent operating system running on the basis of the CPU enters a working state or starts a positioning function, data such as position information and a timestamp in positioning system information can be directly obtained from the MCU in a synchronous manner, for example: the set time before the starting time of the CPU is up to the starting time of the CPU, and the position information of the first electronic device and the timestamp information corresponding to the position information are determined by the MCU, for example: longitude, latitude, and timestamp information corresponding to the longitude and latitude. The CPU may perform time-efficient positioning information processing according to the positioning system information by using a corresponding application program, for example: and drawing a motion circuit diagram in a set time period.
Therefore, the integrity and timeliness of the positioning system information of the CPU can be ensured, the situation that an intelligent operating system running based on the CPU cannot acquire the positioning information during the sleep or shutdown period of the CPU is avoided, and the application which needs to utilize the position information with the timestamp information for positioning data analysis can be normally used.
