Description

换站调度装置及方法
【技术领域】
本发明涉及无线调度系统领域，特别是涉及一种换站调度装置及方法。
【背景技术】
在轻轨或铁路无线调度系统中，采用了GPS换站的方法。这种方法是车载设备利用GPS模块收集GPS数据，通过短信将GPS数据上传到调度服务器，服务器使用算法处理GPS数据，计算出车载设备所到达的站点，并将该站点信息以短信形式反馈给车载设备并在界面上切换车站名称的显示，从而实现了车载设备站点的切换。然而车载设备接收GPS数据后通过无线信道上传到调度中心，数据量过大可能造成无线信道拥塞，而且车载设备通过调度中心间接实现换站，可能存在滞后。
【发明内容】
本发明主要解决的技术问题是提供一种换站调度装置及方法，以解决数据量过大造成无线信道拥塞及换站滞后的问题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种换站调度装置，包括：
存储单元，用于预先存储各个站的范围数据；
定位单元，用于接收当前定位数据；
处理单元，连接所述存储单元及所述定位单元，用于从所述定位单元接收所述当前定位数据并获取所述当前定位数据的信息，在获取的当前定位数据信息在预先存储的下一站的范围数据内时，所述处理单元输出切换信号及上传信号；
切换单元，连接所述处理单元，用于从所述处理单元接收所述切换信号并根据所述切换信号将当前站切换至下一站；及
输出单元，连接所述处理单元，用于从所述处理单元接收所述上传信号并将所述上传信号发送给调度中心。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种换站调度方法，包括：
通过存储单元预先存储各个站的范围数据；
通过定位单元接收当前定位数据；
通过处理单元接收所述当前定位数据并获取所述当前定位数据的信息；
判断获取的当前定位数据信息是否在预先存储的下一站的范围数据内；
若获取的当前定位数据信息在预先存储的下一站的范围数据内，所述处理单元输出切换信号及上传信号；
通过切换单元接收所述切换信号并根据所述切换信号将当前站切换至下一站；及
通过输出单元接收所述上传信号并将所述上传信号发送给调度中心。
本发明的有益效果是：区别于现有技术的情况，本发明所述换站调度装置及方法通过定位单元接收当前定位数据并将其输出给处理单元，以使处理单元获取当前定位数据的信息，在获取的信息在预先存储的经纬度范围内，通过切换单元切换至下一站，同时通过输出单元将下一站的信息通过短信的方式上传给调度中心，以使调度中心能同步更新站点信息，所述换站调度装置能自行处理接收到的GPS数据并根据处理结果自行更新当前车站的信息，以此解决了数据量过大造成无线信道拥塞及换站滞后的问题。
【附图说明】
图1是本发明换站调度装置的第一实施例的方框示意图；
图2是本发明换站调度装置的第二实施例的方框示意图；
图3是本发明换站调度方法的流程示意图。
【具体实施方式】
请参阅图1，是本发明换站调度装置的第一实施例的方框示意图。所述换站调度装置100包括存储单元10，用于预先存储各个站的范围数据；定位单元20，用于接收当前定位数据；处理单元30，连接所述存储单元10及所述定位单元20，用于从所述定位单元20接收所述当前定位数据并获取所述当前定位数据的信息，判断获取的当前定位数据信息是否在预先存储的下一站的范围内，若获取当前定位数据信息在预先存储的下一站的范围数据内，所述处理单元30输出切换信号及上传信号；切换单元40，连接所述处理单元30，用于从所述处理单元30接收所述切换信号并根据所述切换信号将当前站切换至下一站；输出单元50，连接所述处理单元30，用于从所述处理单元30接收所述上传信号并将所述上传信号发送给调度中心200。
在本实施例中，所述存储单元10为本地数据库，所述范围数据为各个站的经纬度范围。所述定位单元20为GPS单元，用于每隔1到5秒接收GPS数据。所述上传信号为短信，所述上传信号通过无线通信发送给调度中心200，以使调度中心200同步更新换站信息。所述换站调度装置100设置在车头或者车尾。
请参阅图2，是本发明换站调度装置的第二实施例的方框示意图。所述换站调度装置100的第二实施例与上述第一实施例的区别之处在于：还包括显示单元60，连接所述切换单元40，用于在所述切换单元40将当前站切换至下一站时显示下一站的信息，所述下一站的信息为下一站的名称。
在其他实施例中，也可为扬声单元，其通过播放语音显示下一站的信息。
例如，假设某一列车正在从当前站（如西安站）开往下一站（如郑州站），所述换站调度装置100设置在所述列车的车头或者车尾，换站调度装置100通过定位单元20每隔1到5秒钟接收GPS数据并将其发送给处理单元30，以使其提取出该GPS数据中的经纬度信息，并将其与存储在存储单元10中的预先存储的下一站的经纬度范围进行比较，如果发现列车当前进入了下一站（即提取到的GPS数据中的经纬度信息在预先存储的经纬度范围内），换站调度装置100就通过切换单元40自动切换车站，即切换至下一站（郑州站），同时通过输出单元50发送一条短信以将当前车站信息（郑州站）上报到调度中心200。这样，调度中心200就可以同步更新该列车当前所在的车站。在轻轨或列车的无线调度系统中，换站调度装置100通过使用算法处理这些GPS数据，从而计算出列车当前所在的车站，并且自行更新换站调度装置的当前车站信息，例如，刷新界面显示的当前车站名称。同时，换站调度装置100通过无线信道上报一条短信给调度中心200，调度中心200就可以同步更新该列车所到达的车站。因此，所述换站调度装置100通过自行处理接收到的GPS数据并根据处理结果自行更新当前车站的信息，以此解决了大量的GPS数据在无线信道频繁传输造成的堵塞及换站滞后的缺点，从而实现快速、稳定、可靠的列车切换车站的目的。
请参阅图3，是本发明换站调度方法的流程示意图。所述方法包括：
步骤S1：通过存储单元10预先存储各个站的范围数据。
步骤S2：通过定位单元20接收当前定位数据。
步骤S3：通过处理单元30获取所述当前定位数据的信息；
步骤S4：判断获取的当前定位数据信息是否在预先存储的下一站的范围数据内。
步骤S5：若获取的当前定位数据信息在预先存储的下一站的范围数据内，所述处理单元30输出切换信号及上传信号。
步骤S6：通过切换单元40接收所述切换信号并根据所述切换信号将当前站切换至下一站。
步骤S7：通过输出单元50接收所述上传信号并将所述上传信号发送给调度中心200。
其中，在步骤S4之后还包括：
若获取的当前定位数据信息不在预先存储的下一站的范围数据内，返回通过定位单元20接收当前定位数据的步骤。
其中，在步骤S5之后还包括：
通过显示单元60在所述切换单元40将当前站切换至下一站时显示下一站的信息，所述下一站的信息为下一站的名称。
在本实施例中，所述存储单元10为本地数据库，所述范围数据为各个站的经纬度范围；所述定位单元20为GPS单元，用于每隔1到5秒接收GPS数据；所述上传信号为短信，所述上传信号通过无线通信发送给调度中心200，以使调度中心200同步更新换站信息；所述换站调度装置100设置在车头或者车尾。
所述换站调度装置及方法通过定位单元接收当前定位数据并将其输出给处理单元，以使处理单元获取当前定位数据的经纬度信息并将其与预先存储的下一站的经纬度范围进行比较，若获取的经纬度信息在预先存储的经纬度范围内，则通过切换单元切换至下一站并显示相应信息，同时通过输出单元将下一站的信息通过短信的方式上传给调度中心，以使调度中心能同步更新站点信息，所述换站调度装置能自行处理接收到的GPS数据并根据处理结果自行更新当前车站的信息，以此解决了数据量过大造成无线信道拥塞及换站滞后的问题。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
