下面参考附图描述本公开实施例的移动计轴装置、轨道、轨道交通系统和控制系统。
由于现有的计轴只适用于固定编组的列车，无法根据列车的编组数对区段进行调整。
针对上述问题，本公开实施例提出了一种移动计轴装置，根据列车的编组数驱动该移动计轴装置移动到指定位置，进而实现区段的调整，使区段的长度与列车编组数相匹配，增大列车追踪密度，缩小追踪间隔，提高轨道资源的利用效率。
图1为本公开一实施例提出的移动计轴装置的结构示意图，其中，列车可以是轻轨、跨坐式单轨等城市交通工具，本实施例以跨坐式单轨对本公开进行说明。
如图1、图2和图8所示，移动计轴装置包括：
箱体1，箱体1位于轨道梁23上的第一凹槽11内，第一凹槽11沿轨道梁23的延伸方向设置；
计轴磁头2，计轴磁头2固定在箱体1上，用于检测经过的列车的车轮对；
计数单元203，计数单元203位于箱体1内且与计轴磁头2连接，用于计算经过的车轮数量；
驱动轮3，驱动轮3固定在箱体1上且可沿轨道梁23的延伸方向滚动；以及
计轴驱动单元202，计轴驱动单元202可驱使驱动轮3滚动。
本实施中的移动计轴装置可以位于轨道梁23的两侧，也可以位于轨道梁23的走行面，检测的列车的车轮对可以是列车的走行轮、稳定轮或导向轮。其中，计轴驱动单元202和计数单元203均位于箱体1的内部，防止受到外部环境的影响，避免受到损坏。
该移动计轴装置属于单磁头的计轴器，该移动计轴装置设置了导向轮和驱动轮3，其中，导向轮包括第一导向轮6和第二导向轮8。计轴驱动单元202为电动机，电动机为驱动轮3提供滚动的动力使移动计轴装置移动。计轴控制单元201位于箱体1内部且与计轴驱动单元202连接，用于控制计轴驱动单元202为驱动轮3提供动力。其中，计数单元203与计轴控制单元201集成在一个电路板上。箱体1上还设有磁传感器12，当移动计轴装置移动到指定位置时，该磁传感器12可以帮助移动计轴装置探测到磁性件13，移动计轴装置停止移动，轨道梁23上的固位部15卡入箱体1上的固位槽14中。该移动计轴装置通过信号/电源收发杆9进行供电和收发信息。
作为一种示例，如图1至图2所示，箱体1的第一侧板4和第二侧板5上均固定有多个驱动轮3。其中，第一侧板4位于箱体1的上方，第二侧板5位于箱体1的下方。在一些实施例中，第一侧板4上的驱动轮3和第二侧板5上的驱动轮3均为两个。其中，第一侧板4和第二侧板5分别位于箱体1的上方和下方，驱动轮3的轴向方向为上下方向。驱动轮3为该移动计轴装置提供前进的摩擦力，驱动轮3滚动，该移动计轴装置可沿前后方向移动，驱动轮3的动力由箱体1内部的电动机提供。第三侧板7上设有多个第一导向轮6，第一导向轮6的轴向方向为上下方向，驱动轮3和第一导向轮6相互配合可平衡左右方向的弹性应力，避免移动计轴装置因外界条件变化造成的左右方向的位移。第一导向轮6的轮轴上设置有弹性件，使移动计轴装置在左右方向上始终保持弹性应力，保持这种合适的弹性应力可以使驱动轮3受力并保证前进的摩擦力。第一导向轮6还可引导移动计轴装置沿前后方向进行移动。
作为一种示例，如图1至图2所示，第二导向轮8为多个，在一些实施例中，第一侧板4上设有两个第二导向轮8，第二侧板5上设有两个第二导向轮8，第二导向轮8的轴向方向为左右方向。第二导向轮8可平衡该移动计轴装置绕左右方向的位移，即避免前后移动的方向发生偏转。第二导向轮8还可引导该移动计轴装置沿前后方向移动。第二导向轮8的轮轴上还设有弹性件，确保该移动计轴装置始终保持弹性应力。
作为一种示例，如图1至图2所示，信号/电源收发杆9与固定在轨道梁23上的信号/ 电源线10连接，类似于高铁的受电弓，其采集头可采用滑槽式，即，信号/电源收发杆9的一端设有容纳信号/电源线10的第二凹槽16，信号/电源收发杆9可沿左右方向伸缩，该移动计轴装置沿前后方向移动时，信号/电源线10一直位于第二凹槽16内，确保信号/电源收发杆9和信号/电源线10接触良好，转弯时也可保证接触良好。优选地，信号/电源收发杆9的另一端设有弹性件，可实现信号/电源收发杆9沿左右方向的伸缩。信号/电源收发杆9的数目可以根据移动计轴装置的型号或信号处理方式决定。具体地，信号/电源收发杆9位于第三侧板7上且另一端连接到箱体1内部的信号处理器或电源处理器中，进而可实现信号的收发或电源的供电。本实施例仅为一种可选的实施方式，不能理解为对本公开的限制，本领域的普通技术人员在本公开的范围内可以对上述实施例进行变化、修改、替换和变型，例如，该移动计轴装置可通过无线的方式进行信号的收发或者电源的供电。
作为一种示例，如图1和图3所示，磁传感器12用于该移动计轴装置的定位。该移动计轴装置沿轨道梁23移动到指定位置后，磁传感器12可探测到指定位置的磁性件13，此时，该移动计轴装置停止移动，防止移动距离不准确。具体地，磁传感器12的探测头位于第三侧板7上，磁性件13位于轨道梁23的对应位置上。其中，第三侧板7位于箱体1的右方。
作为一种示例，如图2至图3所示，箱体1上设有固位槽14，轨道梁23对应位置设有与固位槽14相匹配的固位部15，该移动计轴装置移动到指定位置后固位部15的一端卡入固位槽14，以防列车经过时引起的震动使其发生移动。在一些实施例中，如图9所示，固位槽14的内部设有第一齿状结构141，齿数为6-8齿，固位部15的一端设有第二齿状结构151，齿数为3-4齿，第二齿状结构151的齿长于第一齿状结构141的齿。第一齿状结构141以固位部15下落位置的中轴线两侧平均分布。其中，较多的齿数可以容许该移动计轴装置一定的固位误差。具体地，固位槽14为多个且位于第四侧板上，第四侧板位于箱体1的左方。
本公开实施例的移动计轴装置，通过设置驱动轮3以及计轴驱动单元202，计轴驱动单元202为驱动轮3滚动提供动力，可根据列车的编组数驱动该移动计轴装置移动到指定位置，进而实现区段的调整，使区段的长度与列车编组数相匹配，增大列车追踪密度，缩小追踪间隔，提高轨道资源的利用效率。
为了实现上述实施例，本公开还提出了一种轨道，包括轨道梁23，该轨道梁23可以应用于前述实施例的移动计轴装置。
如图2至图4所示，作为一种示例，轨道梁23设有可容纳该移动计轴装置的第一凹槽11，第一凹槽11沿轨道梁23的延伸方向设置且位于轨道梁23的左侧或则右侧，该移动计轴装置可沿第一凹槽11前后移动。其中，第一侧板4上的驱动轮3位于轨道梁23上的第 一侧壁17和第三侧壁19之间且可沿第一侧壁17滚动，第二侧板5上的驱动轮3位于轨道梁23上的第二侧壁18和第三侧壁19之间且可沿第二侧壁18滚动。第一导向轮6抵接第三侧壁19且可沿第三侧壁19滚动。驱动轮3通过挤压第一侧壁17或第二侧壁18为第一导向轮6提供挤压第三侧壁19的弹性应力，第一导向轮6通过挤压第三侧壁19为驱动轮3提供挤压第一侧壁17或第二侧壁18的弹性应力，两者相互配合可平衡左右方向的弹性应力，避免移动计轴装置因外界条件变化造成的左右方向的位移，确保驱动轮3与第一侧壁17或第二侧壁18之间的弹性应力，为该移动计轴装置沿前后方向移动提供摩擦力。
作为一种示例，第一侧板4上的第二导向轮8抵接第四侧壁20可沿第四侧壁20滚动，第二侧板5上的第二导向轮8抵接第五侧壁21且可沿第五侧壁21滚动。其中，第二导向轮8位于第四侧壁20和第五侧壁21之间，第一侧板4上的第二导向轮8与第二侧板5上的第二导向轮8相互配合，保持该移动计轴装置在上下方向上的弹性应力，避免移动方向发生偏转。
作为一种示例，轨道梁23的第三侧壁19上设有第三凹槽22，信号/电源线10位于第三凹槽22内且与集中站的联锁和电源相连接，用于为移动计轴装置供电及提供信号交互。具体地，信号/电源线10可采用软质材料或硬质材料制作，若采用软质材料制作，则需要在轨道梁23上设置较多的支撑架，并且信号/电源收发杆9需要越过限界与该信号/电源线10抵接，以信号/电源线10的自身弹性保持持续的接触；若采用硬质材料制作，则需要在轨道梁23上设置较少的支撑架，信号/电源收发杆9的另一端需要设置弹性件以增加弹性应力，保持两者接触良好。
作为一种示例，如图2、图3和图8所示，轨道梁23上设有固位模块100，固位模块100包括固位控制单元101、固位驱动单元102和固位部15，其中，固位驱动单元102为电动机。该移动计轴装置移动到指定位置后，固位控制单元101控制固位驱动单元102驱动固位部15绕转动轴旋转，固位部15的一端可卡入固位槽14。具体地，固位部15为多个且分别位于轨道梁23的第六侧壁和第七侧壁上，其中，第六侧壁和第七侧壁上的固位部15可为一个或多个。
需要说明的是，信号/电源收发杆9、磁传感器12和固位槽14可以安装在该移动计轴装置的任意位置，相应的，该轨道梁23只需在对应位置设置信号/电源线10、磁性件13和固位部15，附图和说明书中的相关内容仅作为示例进行说明，而不能作为对本公开的限制。
本公开实施例的轨道梁23，通过设置用于容纳移动计轴装置的第一凹槽11，移动计轴装置可沿第一凹槽11移动，可根据列车的编组数驱动该移动计轴装置移动到指定位置，进而实现区段的调整，使区段的长度与列车编组数相匹配，增大列车追踪密度，缩小追踪间 隔，提高轨道资源的利用效率。
为达上述目的，本公开实施例还提出了一种轨道交通系统，如图2和图3所示，轨道交通系统包括上述的移动计轴装置和轨道梁23。
为了实现上述实施例，本公开还提出了一种控制方法，该方法可以应用于前述实施例的移动计轴装置中。图5为本公开一实施例提出的控制方法的流程示意图。
如图5所示，该控制方法可以包括以下步骤：
S11，移动计轴装置根据收到的允许移动的信息进行移动。
若计轴控制单元201收到允许移动的信息，该信息包括移动的方向和移动的距离，则移动计轴控制单元201控制计轴驱动单元202为驱动轮3提供滚动的动力，移动计轴装置可向指定位置移动。
S12，移动计轴装置移动到指定位置后，对移动计轴装置进行固定。
当移动计轴装置移动至指定位置后通过固位部15卡入固位槽14进行固定，以防列车经过时造成的震动使其发生移动。
在移动计轴装置移动的过程中，难免出现移动计轴装置故障、轨道梁23故障或者移动方向错误的问题，导致无法正常移动。因此，为了解决这一问题，本公开实施例提出了两种可能的实现方式。
作为其中一种可能的实现方式，移动计轴装置在移动的过程中不断反馈移动状态，若移动计轴装置移动方向错误、轨道梁23出现故障或者移动计轴装置出现故障，则发送报警信息，并通过人工的方式解决相关故障。
作为另一种可能的实施方式，可通过移动计轴装置反馈的移动状态信息中获知移动的速度，根据移动距离和移动速度计算出移动计轴装置移动所需的时间，若超过时间，移动计轴装置没有到达指定位置，则判断移动计轴装置丢失并通过人工的方式解决相关故障。
为了避免移动计轴装置移动到指定位置后无法固定，作为另一种可能的实施方式，通过发送报警信息并通过人工的方式解决相关故障。
如图6所示，作为其中一种可能的实现方式，该控制方法还包括：
S13，根据区段占用状态、移动计轴装置是否具有移动的条件以及即将经过区段的列车编组数判断是否允许移动计轴装置移动，若区段为空闲状态，移动计轴装置具有移动的条件，即移动计轴装置和轨道梁23正常，且即将经过区段的列车编组数与区段的长度不匹配，即列车的长度大于或者小于区段的长度，则允许移动计轴装置移动；否则，不允许移动计轴装置移动。具体地，若列车的长度大于区段的长度，则移动计轴装置向扩大区段长度的方向移动，并确定移动的距离；若列车的长度小于区段的长度，则移动计轴装置向缩小区段长度的方向移动，并确定移动的距离。
本实施例的控制方法，移动计轴装置根据收到的允许移动的信息进行移动，移动计轴装置移动到指定位置后，对移动计轴装置进行固定，可根据列车的编组数驱动该移动计轴装置移动到指定位置，进而实现区段的调整，使区段的长度与列车编组数相匹配，增大列车追踪密度，缩小追踪间隔，提高轨道资源的利用效率。
为了实现上述实施例，本公开还提出一种控制系统。
图7为本公开一实施例提出的控制系统的结构示意图。如图7所示，该控制系统包括：
计轴模块200，计轴模块200包括移动计轴装置；
控制模块300，控制模块300与计轴模块200连接，用于控制移动计轴装置的移动；和
固位模块100，固位模块100与计轴模块200连接，用于阻止或允许移动计轴装置移动。
作为一个示例，移动计轴装置接收控制模块300发送的移动信息，并根据移动信息移动到指定位置，同时向控制模块300发送到位信息，控制模块300根据到位信息向固位模块100发送固位信息，固位模块100根据固位信息对移动计轴装置进行固定。
作为一个示例，如图7所示，计轴模块200、控制模块300和固位模块100通过总线连接，并在数据传输上具有优先级划分。其中，总线采用双缆制，一条电缆设置为高压电线，另外一条设置为低压电线，在总线连接的各个模块中均有相应的数据处理单元及终端电阻(类似于CAN总线，但CAN总线数据传输介质一般为双绞线或同轴电缆)。发送信息的模块经过逻辑判断后，可以通过其数据处理单元向总线发送数据，接收信息的模块的数据处理单元根据数据帧标志位对总线数据进行筛选，并对符合通信协议的数据帧进行校验处理工作，当数据帧有丢失位或位错误时，数据处理单元可以及时向总线返回数据帧错误信号，放弃该数据帧的使用权，并请求重发。发送信息的模块接收到重发的信息后立刻重发该数据帧。
如图8所示，控制模块300包括主机控制单元301、智能监控单元302和联锁单元303。其中，主机控制单元301用于判断区段的状态和移动计轴装置的状态，以及控制移动计轴装置工作。智能监控单元302用于判断区段的状态和移动计轴装置的状态是否允许移动计轴装置移动。联锁单元303用于控制控制模块300复位清零。
具体地，计数单元203计算经过的车轮对数量并将列车的轮对数发送给主机控制单元301，主机控制单元301通过接收到的轮对数信息判断区段的状态，即区段为空闲状态或占用状态。计轴控制单元201将移动计轴装置的状态发送给主机控制单元301，主机控制单元301根据接收的状态信息判断移动计轴装置是否满足移动的条件，即是否故障。主机控制单元301将区段的状态与移动计轴装置的状态发给智能监控单元302和联锁单元303， 智能监控单元302接收并记录区段和移动计轴装置的状态并判断是否允许移动计轴装置移动，即逻辑判断列车将要通过的区段长度是否需要调整，主机控制单元301根据智能监控单元302的允许移动信息控制移动计轴装置移动。联锁单元303可向主机控制单元301发送复位信息，控制模块300进行复位清零操作。
智能监控单元302存在数据接口，主机控制单元301可以从该数据接口中接收到即将通过该区段的列车编号、其编组数以及允许移动的信息，其数据帧格式由智能监控单元302相关数据报文定义。当主机控制单元301接收到信息(在智能监控单元302中，列车编号的报文可以设置为带有编组信息的格式)之后，如果需要调整区段的长度，则查询需要移动的移动计轴装置信息，获得适合该列车编组数的移动计轴装置，移动计轴装置的移动方向及需要到达的指定位置，生成符合协议的数据帧传输至总线，该数据帧设置为8位：
Figure PCTCN2019088117-appb-000001
主机控制单元301将允许移动的信息发送至指定编号的移动计轴装置的计轴控制单元201，并由计轴控制单元201将移动信息发送至计轴驱动单元202及指定位置的固位控制单元101。固位控制单元101接收到移动信息后，优先抬起固位部15，由于固位模块100的计轴驱动单元202为电动机，可对电动机的转动弧度进行抬角判断，若抬起角度与预先指定的角度不符，反馈固位模块100故障至移动计轴控制单元201，移动计轴控制单元201将信息发送至主机控制单元301，由主机控制单元301将故障信息反馈至智能监控单元302，且主机控制单元301经由联锁接口向联锁单元303反馈故障所在区段的状态信息。智能监控单元302接收并核对故障信息，再次发送移动信息，若仍收到故障信息，则不再下发移动指令，将故障上报至中心调度工作站，故障消除后，更新故障状态。其中，固位模块100未成功抬起故障信息帧为8位：
Figure PCTCN2019088117-appb-000002
若固位模块100抬起成功，固位部15脱离固位槽14，则通过总线发送数据帧给计轴控制单元201，移动计轴装置收到信息后进行移动。计轴控制单元201可通过移动计轴装置预停留位置判断出将要经过的磁性件13的数量N，每当其掠过一个磁性件13，则N＝N-1，直至N＝0(移动计轴装置经过所有中间停靠点)，计轴控制单元201判断出到达指定位置，并控制移动计轴装置停止。转发的数据帧依旧为8位：
Figure PCTCN2019088117-appb-000003
若固位模块100抬起恢复正常且智能监控单元302检测到移动计轴装置状态正常，智能监控单元302结合即将到达的列车位置信息和联锁单元303发送的已办理的进路信息，再次向主机控制单元301发送下移动信息。
计轴驱动单元202根据移动信息驱动移动计轴装置沿指定的方向移动，其中，计轴驱动单元202为电动机，计轴控制单元201检测到电机转动一周后发送反馈信息至智能监控单元302，若该电动机长时间未转动或转动不满一周，则计轴控制单元201向智能监控单元302反馈故障。当移动计轴装置成功转动一周后，计轴控制单元201发送的反馈信息的数据帧为16位：

当移动计轴装置移动至指定位置后，磁传感器12检测到磁性件13的存在并发送信息给计轴控制单元201，计轴控制单元201控制计轴驱动单元202停止转动(也可以设置短暂延时)，计轴控制单元201检测到计轴驱动单元202停止转动后，发送信息给智能监控单 元302和联锁单元303，智能监控单元302向固位模块100发送固位信息，固位驱动单元102根据固位控制单元101发送的信息驱动短暂延时后落下并卡入固位槽14。智能监控单元302可在移动计轴装置移动前估算出移动计轴装置移动到指定位置所需的时间，若超过该时间移动计轴装置仍未反馈馈电动机停转信信息，智能监控单元302判断移动计轴装置丢失，联锁单元303更新/维持区段状态。当计轴控制单元201检测计轴到达指定位置，发送16位数据帧给主机控制单元301：

当主机控制单元301检测到上述信息后，发送8位数据帧控制固位模块100落下，其中，固位模块100读取计轴停留位置编号来判断是自身是否为指定位置的固位模块100：
