本发明涉及轨道列车领域，特别是涉及一种轨道列车的空调控制系统。此外，本发明还涉及一种包括上述空调控制系统的轨道列车。
背景技术
随着铁路事业的不断发展，高速动车组已经贯穿大江南北。但因南北气候的差异较大，对于动车组来说，短时间内以高速穿越不同气候带，需要做好各种适应性设计和控制。尤其对于空调系统来说，不仅南北气候温差大，北方冬季检修和维护也需要对设备有特殊的保护措施。北方冬季，车辆运行时环境温度超低，有时甚至有冰雪天气，而融雪、检修、维护等需要在常温下进行，这样室内外温差最大可达到60K以上，因此就要求车辆不仅配备有能适应环境温差突变的硬件设备，还要有合理的控制方法来适应这种巨大的温差突变情况。
目前，高速动车组的空调系统都采用自动控制，自动控制的逻辑能够满足正常工况下的舒适性需求。但是对于应用于高寒地区的空调系统来说，仅仅是通用性的自动控制无法满足高寒环境的需求。
现有的空调系统，在遇到低温暴雪天气，空调机组冷凝腔会被冰雪封住，部分设备甚至会结块冰堵。对于低温运营状态，普通车辆仅有低温库外带电存放的防冻启动措施，而没有包括应对运营和检修、维护等方面的低温环境下的控制系统应对措施。
因此，提供一种能适应高寒地区运行环境，且能够在高寒地区更好的控制车厢空调温度的同时保护空调系统的各个设备不被损坏的空调控制系统是本领域技术人员目前需要解决的技术问题。

防冻判断单元，用于判断T 外是否小于等于预先设定的温度T f，如果判断结果为是，则所述控制器中枢处理单元优先启动空调系统防冻模式。
优选地，还包括计时单元，用于记录所述低温车辆维护模式持续运行的时间；

    运行时间判断单元(8)，用于判断所述低温车辆维护模式持续运行的时间是否超过第二预设时间S2，以及有无其他手动命令输入，若前者为是且后者为无，则所述控制器中枢处理单元(3)控制空调系统切换到自动控制模式或加热设备运营模式。
  3. 根据权利要求2所述的空调控制系统，其特征在于，还包括门廊温度传感器(9)，设于车厢门廊处并通信连接所述控制器中枢处理单元(3)，用于获取车内门廊处温度；
    温度修正单元(10)，用于根据公式T h＝T s+△T h，修正门廊通过台控制点设定温度，其中，T h为高寒环境下门廊通过台控制点设定温度值，T s 为常规环境下门廊通过台控制点温度设定值，△T h为高寒门廊环境温度控制点修正值；
    所述控制器中枢处理单元(3)根据所述温度修正单元(10)的修正结果，控制加热设备的启停时间，使车内门廊处温度保持在所述高寒环境控制点设定温度值T h。
  4. 根据权利要求3所述的空调控制系统，其特征在于，还包括加热设备反馈时间修正单元(11)，用于根据公式S h＝S s+△S h，修正加热设备启动的反馈识别时间，其中，S h为高寒环境空调控制器中枢处理单元(3)允许识别的反馈识别时间，S s为常规环境控制点反馈时间，△S h为高寒环境温度反馈时间修正值。
  5. 根据权利要求1至4任意一项所述的空调控制系统，其特征在于，还包括通信连接所述控制器中枢处理单元(3)的人机交互器(12)，所述人机交互器(12)上设置有用于控制所述空调系统进入低温车辆维护模式的按钮，供司机手动启动低温车辆维护模式。
  6. 根据权利要求5所述的空调控制系统，其特征在于，在手动启动低温车辆维护模式下，所述控制器中枢处理单元(3)控制所述空调系统的各个设备关闭，而只有司机室的通风开启。
  7. 根据权利要求6所述的空调控制系统，其特征在于，在低温车辆维护模式下，所述控制器中枢处理单元(3)控制司机室通风开启，并控制客室空调机组和新风格栅关闭。
  8. 根据权利要求7所述的空调控制系统，其特征在于，所述人机交互器(12)上设置有用于控制所述空调系统退出低温车辆维护模式的按钮。
  9. 一种轨道列车，包括空调控制系统，其特征在于，所述空调控制系统具体为权利要求1至8任意一项所述的空调控制系统。
