由此可知,如图1和图2所示,轨道平车运行在轨道上,通过无线通信模块与远处的远程监控模块进行通信,远处的工作人员可以实时监控现场的轨道平车的运行状态,尤其可以实时监测到轨道上的轨道平车的电量,其中无线通信模块包括WiFi、4G或者无线电波,远程监控模块包括计算机和信号接收端,通过计算机对远处的轨道平车进行操控。轨道平车上设有控制模块,控制模块包括单片机,通过单片机来控制定位模块、自动驾驶模块和非接触式充电电源模块,其中定位模块包括GPS定位系统或北斗定位导航系统,自动驾驶模块包括图像识别芯片组、超声波传感器、红外传感器以及雷达等,通过这些传感器的数据来实时控制轨道平车的电机,进而实现轨道平车的自动驾驶。当远程监控模块监测到轨道平车的电量不足时,发送指令给控制模块,控制模块控制控制非接触式充电电源模块开始充电。具体地,所述非接触式充电电源模块包括蓄电池及充电桩组,所述充电桩组上设有初级线圈组,充电桩组设在轨道上,蓄电池设有与所述初级线圈组对应的次级线圈,初级线圈上通交流电时,通过电磁感应即可在次级线圈上形成电流,便可以实现充电过程,充电的开始与关闭都是通过控制模块来控制。由于充电方式为非接触式,因此轨道平车可以在工作的同时进行充电。
该运行于轨道上的采用蓄电池动力的集装箱轨道平车,包括由两个端部车体与中间的集装箱运输车体组成的一体化车身,中间车体可装载两个20ft集装箱或一个40ft集装箱。两个端部车体下分别安装一台两轴转向架,两轴转向架与端部车体构架间设置心盘联接。
优选地方案,还设有报警模块,所述报警模块用来监测所述自动驾驶模块、所述定位模块、所述无线通信模块、所述控制模块、所述远程监控模块及所述非接触式充电电源模块的工作状态。当所述自动驾驶模块、所述定位模块、所述无线通信模块、所述控制模块、所述远程监控模块及所述非接触式充电电源模块中的任一一个模块出现故障后便开始报警,远程的工作人员便可以操控该轨道平车退出作业现场或停下来等待检修。
优选地方案,当所述蓄电池电量低于预设阈值时,所述控制模块控制所述轨道平车运行至最近的所述充电桩处进行充电。由此可知,控制轨道平车至最近的充电桩处进行静止充电,能最快将电充满,也可以边工作边充电。
优选地方案,所述定位模块包括GPS/GPRS定位、惯性导航、激光辅助精确定位及电子地图。
优选地方案,所述初级线圈组包括多段初级线圈,多段所述初级线圈间隔铺设在轨道上,所述车体的下端设有与所述初级线圈对应的次级线圈。由此可知,输入电源从配电所获取电能后,经过第一整流滤波电路整流滤波后,输出直流电至高频逆变器,产生的高频交变电流在控制开关的控制下,输入至分离式耦合变压器的初级线圈绕组,初级线圈绕组为敷设在轨道内平行于轨道的一个个独立分段供电线圈。初级线圈绕组在临近空间产生耦合高频交变磁通,通过感应耦合产生的高频交变磁通,使位于轨道平车底架上的次级线圈绕组获取感应电动势,再经过第二整流滤波电路后,完成向车载蓄电池快速充电。充电系统通过分离式耦合变压器交换能量,实现了轨道平车能够在运行中随时充电。
优选地方案,所述初级线圈与所述次级线圈之间的最小距离不大于15cm。保证充电安全且高效。

优选地,所述轨道平车前后端均设有激光测距传感器和/或超声波测距传感器。传感器起到辅助定位和导航的作用。
