本发明的实施方式Embodiments of the invention
下文中将参考附图并结合实施例来详细说明本发明实施例。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
本发明的实施例提供一种星历更新方法，图1是根据本发明实施例的星历更新方法的流程图，如图1所示，该方法包括步骤S102和步骤S104。An embodiment of the present invention provides a ephemeris update method. FIG. 1 is a flowchart of a ephemeris update method according to an embodiment of the present invention. As shown in FIG. 1, the method includes steps S102 and S104.
步骤S102：获取使用中星历有效期限。Step S102: Acquire an expiration date of the ephemeris in use.
导航***并不经常主动检测当前星历有效性，只是在启动时才进行检测或者更新。通过主动获取当前星历有效期限，可以摆脱启动过程对于检测行 为的限制，能够更为准确和及时判断当前星历有效性。在这里，获取使用中星历有效期限，可以不限于固定方法。例如，可以通过设定预定时间间隔获取使用中星历有效期限，也可以设定在具体的时间节点获取使用中星历有效期限，也可以在满足预定条件时，如抵达指定地点、达到预定电池电量、收到检测操作指令等方式，来触发获取使用中星历有效期限。The navigation system does not often actively detect the validity of the current ephemeris, but only detects or updates it at startup. By actively obtaining the current ephemeris expiration date, it is possible to get rid of the limitation of the detection process on the behavior of the startup process, and to judge the validity of the current ephemeris more accurately and in time. Here, the validity period of the ephemeris in use can be obtained, and it is not limited to the fixed method. For example, the ephemeris expiration date may be obtained by setting a predetermined time interval, or the ephemeris expiration date may be acquired at a specific time node, or when the predetermined condition is met, such as reaching a designated location and reaching a predetermined battery. The power, the receipt of the detection operation command, etc., to trigger the acquisition of the ephemeris validity period in use.
步骤S104：确认使用中星历有效期限小于等于第一预设期限，使用或提示使用预先备份星历更新星历。Step S104: Confirm that the ephemeris validity period in use is less than or equal to the first preset period, and use or prompt to use the pre-backup ephemeris to update the ephemeris.
确认使用中星历有效期限小于等于第一预设期限，例如在导航***使用过程中检测到使用中星历已经失效(即星历有效期限等于0)，或者使用中星历有效期限小于预设期限、被认为即将失效、或可能在有效期限内存在无法联网风险，则可以使用或者提示使用备份星历信息更新星历，使得星历能够在继续保持可用状态，防止星历失效。Confirm that the ephemeris validity period in use is less than or equal to the first preset period, for example, it is detected that the ephemeris in use has expired during the use of the navigation system (ie, the ephemeris validity period is equal to 0), or the ephemeris validity period is less than the preset period. The term, is considered to be about to expire, or may be incapable of networking risk within the validity period, you can use or prompt to use the backup ephemeris information to update the ephemeris, so that the ephemeris can continue to be available to prevent the ephemeris from failing.
在示例性的实施方式中，所述预先备份星历，通过以下方式获得：在第一预设时间，获取使用中星历有效期限；确认所述第一预设时间获取使用中星历有效期限小于第二预设期限时，下载所述备份星历。In an exemplary embodiment, the pre-backing ephemeris is obtained by acquiring an ephemeris expiration date in use at a first preset time, and confirming the first preset time to obtain an ephemeris expiration date in use. When the second preset period is less than the second preset period, the backup ephemeris is downloaded.
第一预设时间可以是预设的时间点，也可以是通过计时器所确定的预设时间点。所述第二预设期限，用于衡量使用中星历是否需要备份。通过获取该时间点上使用中星历有效期限，并确认所述第一预设时间获取使用中星历有效期限小于第二预设期限，则可以认为当前星历需要备份，从而下载所述备份星历。通过在预设时间点比对第二预设期限来判断下载备份星历，能够保证后续面临无网络环境时，存在有效的星历信息可用，同时能够根据不同的状况进行调整，进一步提升防止星历信息失效的效果。The first preset time may be a preset time point, or may be a preset time point determined by a timer. The second preset period is used to measure whether the ephemeris in use needs to be backed up. By obtaining the ephemeris expiration date at the time point and confirming that the first preset time is used to obtain the ephemeris validity period is less than the second preset period, the current ephemeris may be considered to be backed up, thereby downloading the backup. Ephemeris. By comparing the downloading of the backup ephemeris at a preset time point, it is possible to ensure that the effective ephemeris information is available when there is no network environment in the subsequent time, and can be adjusted according to different conditions to further enhance the prevention star. The effect of calendar information failure.
在示例性的实施方式中，在所述下载所述备份星历之前，该方法还包括：检测当前网络状况；若当前网络可用，下载所述备份星历；若当前网络不可用，设定下载所述备份星历计划。In an exemplary embodiment, before the downloading the backup ephemeris, the method further includes: detecting a current network condition; downloading the backup ephemeris if the current network is available; and setting the download if the current network is unavailable The backup ephemeris plan.
下载备份时，如果当前网络正常则下载所述备份星历。如果发现网络不可用，则可以设定延迟一段时间继续尝试下载，或者通过网络连接的历史数据，例如通过历史中通常能够连接网络的时间，或者判断进入地图上有网络记录的区域的时间等，或者设定的能够连接网络的时间，或者提示用户设置 网络传输信号等各种计划方式，来进一步提升下载备份的及时性以及可用性，从而进一步提升防止星历信息失效的效果。When the backup is downloaded, the backup ephemeris is downloaded if the current network is normal. If the network is found to be unavailable, you can set a delay to continue to try downloading, or historical data connected through the network, such as the time when you can usually connect to the network in history, or the time to enter the area on the map with network records. Or set the time to connect to the network, or prompt the user to set various network transmission signals and other planning methods to further improve the timeliness and availability of download backup, thereby further improving the effect of preventing ephemeris information failure.
在示例性的实施方式中，所述方法中所述获取使用中星历有效期限，包括：获取已经存储的备份星历有效期限；相应的，确认所述使用中星历与已经存储备份星历中最长有效期限小于第二预设期限时，下载星历信息更新所述备份星历。In an exemplary embodiment, the obtaining, in the method, the expiration date of the ephemeris in use includes: obtaining an existing ephemeris validity period that has been stored; and correspondingly, confirming the used ephemeris and the stored backup ephemeris When the longest validity period is less than the second preset period, the download ephemeris information updates the backup ephemeris.
通过将使用中星历有效期以及存储的备份星历有效期一起进行判断，可以更好的确认是否需要进行备份，对于使用中星历有效期较短，而存储的备份星历有效期较长的情形，则可以通过该方法判断当前设备中已经有了较新的星历信息，不用进行下载备份以节约流量。而当判断出当前备份信息和使用中信息有效期限均较短时，则可以下载星历信息，从而更好的平衡节约流量与防止星历失效的效果。By judging the validity period of the ephemeris in use and the stored backup ephemeris validity period, it is better to confirm whether backup is required. For the case where the ephemeris in use is valid for a short period and the stored backup ephemeris has a long validity period, This method can be used to judge that there is already newer ephemeris information in the current device, and no download backup is needed to save traffic. When it is judged that the current backup information and the information in use are valid for a short period of time, the ephemeris information can be downloaded, thereby better balancing the effect of saving traffic and preventing ephemeris failure.
在示例性的实施方式中，设定第一预设时间方法包括：In an exemplary embodiment, the setting the first preset time method includes:
按照预设***参数设定；或按照预定时间间隔确定；或按照网络连接历史数据设定。Set according to preset system parameters; or according to predetermined time intervals; or set according to network connection history data.
通过预设***参数设定，可以更为方便的确认第一预设时间，不需要用户进行设定，例如***参数预设间隔1小时检测一次，或者每天的早上6点至晚上12点间隔30分钟检测一次等，可以方便新用户避免设定带来的麻烦；按照预定时间间隔设定，则可以通过预定间隔时间，来判断星历是否过期，一方面通过控制预定间隔时间可以调整判断的精度，另一方面通过该方法也可以较为简单的设定检测时间；按照网络连接历史数据，则可以更好的判断网络状况，根据是否可能存在网络，来判断是否需要判断下载。三种方式各有特点，可以根据具体情况选用，以更好的实现防止星历失效。By preset the system parameter setting, the first preset time can be confirmed more conveniently, and the user does not need to perform setting, for example, the system parameter preset interval is detected once every hour, or every day from 6 am to 12 pm interval 30 If the minute is detected once, it can facilitate the new user to avoid the trouble caused by the setting; according to the predetermined time interval, the elapsed time can be judged by the predetermined interval time. On the other hand, the accuracy of the judgment can be adjusted by controlling the predetermined interval time. On the other hand, the detection time can be set relatively simply by this method; according to the historical data of the network connection, the network status can be better judged, and whether the download is needed depends on whether the network is likely to exist. Each of the three methods has its own characteristics and can be selected according to the specific situation to better prevent the ephemeris from failing.
在示例性的实施方式中，所述方法中所述获取星历有效期限的方式包括：获取当前标准时间，比对所述星历标准时间与所述当前标准时间；或通过最后一次下载标准时间以及运行时间推算当前标准时间，比对所述星历标准时间与所述推算当前标准时间。In an exemplary embodiment, the manner of obtaining the ephemeris expiration date in the method includes: acquiring a current standard time, comparing the ephemeris standard time with the current standard time; or downloading the standard time by the last time And the running time estimates the current standard time, comparing the ephemeris standard time with the estimated current standard time.

Each of the two methods has its own characteristics and can be selected according to the specific situation to better prevent the ephemeris from failing.
图2为根据本发明实施例在GPS导航***工作状态时控制GPS星历下载备份流程图。2 is a flow chart of controlling GPS ephemeris download backup when the GPS navigation system is in an operating state according to an embodiment of the present invention.
在这个实施例中，GPS星历下载备份方法包括步骤S201-步骤S203。In this embodiment, the GPS ephemeris download backup method includes steps S201 to S203.
步骤S201：GPS处于工作状态。Step S201: The GPS is in an active state.
目前的方案只在GPS启动时才会检测星历信息是否有效，若在工作中星历信息失效则不更新。The current scheme only detects whether the ephemeris information is valid when the GPS is started, and does not update if the ephemeris information fails during the work.
步骤S202：设定定时器，以查询星历有效期。Step S202: setting a timer to query the ephemeris validity period.
如每隔一天检查一次星历信息有效性，其中设定定时器的方式有多种，既可以通过***参数默认的方式，例如保持每隔一天或者每隔6个小时查询星历有效期，也可以通过用户自定义的形式进行查询，还可以通过历史数据动态调整该定时器设定值。For example, check the validity of the ephemeris information every other day. There are various ways to set the timer. You can use the default method of the system parameters, such as keeping the ephemeris validity period every other day or every 6 hours. The query can be queried in a user-defined form, and the timer setting can be dynamically adjusted through historical data.
步骤S203：若星历信息失效或者剩余有效期小于预设值，则下载星历数据。Step S203: If the ephemeris information is invalid or the remaining validity period is less than a preset value, the ephemeris data is downloaded.
当星历信息已经失效或者可以预见即将失效时，则下载星历数据。因为此时更新星历数据会消耗时间，并且可能引起GPS工作的不稳定，故可以将星历数据进行暂存，等待合适的时机载入。Ephemeris data is downloaded when the ephemeris information has expired or is expected to expire. Because updating the ephemeris data at this time will take time and may cause unstable GPS work, you can temporarily store the ephemeris data and wait for the appropriate time to load.
图3为根据本发明实施例在GPS启动状态时控制GPS星历更新流程图。3 is a flow chart of controlling GPS ephemeris update in a GPS startup state in accordance with an embodiment of the present invention.
在这个实施例中，GPS星历更新方法包括步骤S301-步骤S306。In this embodiment, the GPS ephemeris update method includes steps S301-S306.
步骤S301：通过AP(Access Point，接入点)(辅助GPS应用侧)判断当前星历是否失效。Step S301: Determine whether the current ephemeris is invalid through an AP (Access Point) (the assisted GPS application side).
目前主要在modem(GPS应用侧)判断星历信息是否失效，现在所有的工作都放在AP。通过AP与modem之间的交互获取当前星历是否失效。At present, mainly on the modem (GPS application side) to determine whether the ephemeris information is invalid, and now all work is placed on the AP. Obtain whether the current ephemeris is invalid through the interaction between the AP and the modem.
步骤S302：检查到星历失效后，使用下载的星历信息数据更新星历。Step S302: After checking that the ephemeris is invalid, the ephemeris is updated using the downloaded ephemeris information data.
如果需要获取最新的星历信息可以考虑通过网络下载，但是考虑到可能没有网络的情形，以及更新所消耗的时间。这里直接使用星历信息的备份数据进行更新。If you need to get the latest ephemeris information, you can consider downloading through the network, but considering the situation where there may be no network, and the time it takes to update. Here, the backup data of the ephemeris information is directly used for updating.
步骤S303：若星历信息未失效，此时检测正在使用的星历信息是否已经超过了有效期的一半。Step S303: If the ephemeris information has not expired, it is detected whether the ephemeris information being used has exceeded half of the validity period.
步骤S304：若正在使用的星历信息已经超过了有效期的一半，则AP会进行星历信息的下载。Step S304: If the ephemeris information being used has exceeded half of the validity period, the AP performs the download of the ephemeris information.
步骤S305：将最新获取的星历信息存储在设备中。Step S305: Store the latest acquired ephemeris information in the device.
当星历信息剩余有效期不足原有效期的一半时，可以推定认为当前星历信息即将失效，为了避免在后续环境中可能出现无网络或者其他状态，这里下载星历信息并存储在设备中以防止星历失效又无法下载的情形。当然，所述剩余有效期不足原有效期的一半属于可预设值，可以根据实际网络环境的需要，调整该预设值，以更好的判断星历是否即将失效。When the remaining validity period of the ephemeris information is less than half of the original validity period, it can be presumed that the current ephemeris information is about to expire. In order to avoid possible network or other state in the subsequent environment, the ephemeris information is downloaded and stored in the device to prevent the star. A situation where the calendar fails and cannot be downloaded. Certainly, the remaining validity period is less than half of the original validity period, and the preset value may be adjusted according to the needs of the actual network environment, so as to better determine whether the ephemeris is about to be invalid.
步骤S306：在GPS工作过程中，定时器查询正在使用的星历信息有效性及存储的星历信息状态。Step S306: During the GPS working process, the timer queries the validity of the ephemeris information being used and the stored ephemeris information status.
通过检测，确保使用的星历信息以及存储的星历信息尽量能够处于有效状态，当超长时间没有网络更新，检测到备份星历信息即将过期时，可以提示当前状态，便于用户选择是否需要前往网络区域或者寻找其他网络接入方法以获取星历信息。Through the detection, ensure that the used ephemeris information and the stored ephemeris information are as valid as possible. When there is no network update for a long time, and the detected ephemeris information is about to expire, the current status can be prompted, so that the user can select whether to go. Network area or look for other network access methods to obtain ephemeris information.
通过本实施例，能够及时检测到当前星历即将过期，并积极进行星历信息备份。当前星历已经过期时，则主动向GPS组件发送备份的星历信息，以完成星历的更新，从而保障快速搜星功能的可用性。Through this embodiment, it is detected in time that the current ephemeris is about to expire, and the ephemeris information is actively backed up. When the current ephemeris has expired, the backup ephemeris information is actively sent to the GPS component to complete the ephemeris update, thereby ensuring the availability of the fast search function.
本发明实施例提供了一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被处理器执行时实现上述的星历更新方法。Embodiments of the present invention provide a computer readable storage medium storing computer executable instructions, which are implemented by a processor to implement the above-described ephemeris update method.
本发明实施例还提供星历更新装置。如图4所示，星历更新装置包括：检测模块11，设置成：获取使用中星历有效期限，确认所述星历有效期限小于等于第一预设期限时通知更新模块13；备份模块12，设置成：存储预先备份星历；更新模块13，设置成：接收到检测模块11星历有效期限不足通知， 使用所述备份模块12中备份星历更新星历。The embodiment of the invention also provides an ephemeris update device.

通过检测当前星历有效性，可以准确判断当前星历是否已经失效或者即将失效。当认为即将失效时，通过备份信息更新星历，以防止无网络状态下无法下载星历或者网络下载缓慢等情形，提高星历的有效性，保证快速搜星功能的使用。By detecting the validity of the current ephemeris, it is possible to accurately determine whether the current ephemeris has expired or is about to expire. When it is considered that it is about to expire, the ephemeris is updated by the backup information to prevent the ephemeris from being downloaded or the network downloading is slow in the absence of the network state, thereby improving the validity of the ephemeris and ensuring the use of the fast search function.
在示例性的实施方式中，所述检测模块是设置成：在第一预设时间，获取使用中星历有效期，确认所述第一预设时间获取的使用中星历有效期限小于第二预设期限时通知下载模块；下载模块设置成：接收到确认剩余有效期限小于第二预设期限通知，下载所述备份星历。In an exemplary embodiment, the detecting module is configured to: obtain the ephemeris validity period in use at the first preset time, and confirm that the ephemeris validity period acquired in the first preset time is less than the second pre-expiration period The download module is notified when the deadline is set; the download module is configured to: receive the confirmation that the remaining validity period is less than the second preset period notification, and download the backup ephemeris.
通过第一预设时间检测，能确保在当前星历有效期低于预设期限时下载备份星历，使得装置中的备份星历处于可用状态。从而进一步保障快速搜星的有效性。By the first preset time detection, it is ensured that the backup ephemeris is downloaded when the current ephemeris validity period is lower than the preset period, so that the backup ephemeris in the device is in an available state.
