具体实施方式
以下结合附图对本发明作进一步详细说明。
参见图1所示，本发明提供一种多功能分流井，其包括井体1、控制装置2、第一水力开关3和第二水力开关4。
其中，井体1上至少设有进水口11、出水口12和污水出水口13，进水口11和出水口12相对设置。
第一水力开关3设于靠近井体1的出水口12处，用于控制出水口12的过水量。本发明中的第一水力开关3为下开式堰门。第一水力开关3主要用于分流井水位达到警戒水位时的泄洪以及防倒灌。
第二水力开关4设于靠近井体1的污水出水口13处，第二水力开关4用于控制污水出水口13的过水量。
控制装置2用于驱动第一水力开关3和第二水力开关4升降。
本发明中的多功能分流井还包括：第一液位计5、第二液位计6和第三液位计7。
其中，第一液位计5，其一端与控制装置2相连，并位于井体1内，第一液位计5用于测量井内液位。
第二液位计6，其一端与控制装置2相连，并位于井体1内，第二液位计6用于测量井外液位。
第三液位计7，其一端与控制装置2相连，并位于污水出水口13内，第三液位计7用于测量污水液位。
控制装置2包括停电处理模块、防倒灌控制模块、天气检测模块、污水检测模块、雨天处理模块和晴天处理模块。根据上述模块，控制装置2相应的具有停电模式、防倒灌模式、雨天模式和非雨天模式四个功能模式。其中优先级由高向低排列为停电模式、防倒灌模式、雨天模式和非雨天模式，进入优先级高的模式的条件出现后，优先完成 高优先级的模式所设计的动作。以下分别对这四个模式进行说明：
(1)停电模式：
停电模式主要涉及到的是停电处理模块，停电处理模块用于检测多功能分流井的供电系统是否停电，若停电则发出报警并锁定第一水力开关3和第二水力开关4所处的位置和状态。在发出报警后，通知操控人员马上处理，防止意外造成污水倒灌或井内水体进河道。
(2)防倒灌模式：
当停电处理模块检测未停电后，防倒灌控制模块用于判断井体1外的井外液位是否大于等于第一井外液位线H1，当井外液位大于等于第一井外液位线H1时，防倒灌控制模块驱动第一水力开关3动作，直至第一水力开关3达到第一高度Q1，且所述第一高度Q1大于第一井外液位线H1。本发明中的第一井外液位线H1可以取为2200mm，第一高度Q1可以取为2500mm，实际液位高度和第一水力开关3的高度应与现场的水文环境相关联选取。
具体而言，当井外液位大于等于第一井外液位线H1时，为防止河水或其他自然水体水位升高而倒灌进入分流井体1，于是控制装置2进入到了防倒灌模式的程序执行策略。首先将防倒灌标识位置1，表示目前控制装置2是防倒灌模式，同时控制第一水力开关3的高度到第一高度Q1，如果第一水力开关3没到指定的第一高度Q1，则程序继续执行，由于防倒灌标识位置为1，所以程序继续执行防倒灌模式的策略，直到第一水力开关3达到指定的第一高度Q1才将防倒灌标识位置0，此时之后，系统才执行低优先级的工作模式。增加防倒灌标识位的目的是为了锁定防倒灌模式，即除了停电模式外，一旦进入到防倒灌模式，其余的工作模式都不能打断防倒灌模式的执行。
控制装置2还用于判断井体1内的井内液位与污水出水口13的 污水液位的差值是否大于上限值a或小于下限值b，若大于上限值a，则防倒灌控制模块驱动第二水力开关4动作，使第二水力开关4打开，若小于下限值b，则防倒灌控制模块驱动第二水力开关4动作，使第二水力开关4关闭。本发明中的上限值a为200mm，下限值b为50mm，a和b的取值可根据实际情况选取。
具体而言，在执行防倒灌模式的程序时，为了最大程度的将井内污水截污到污水管道，即当井内液位与污水液位的差值大于200mm时，应使第二水力开关4打开。为了防止污水倒灌进入井体1，当井内液位与污水液位的差值小于50mm时，应使第二水力开关4关闭。
(3)雨天模式：
雨天模式主要涉及到天气检测模块、污水检测模块、雨天处理模块。天气检测模块用于检测是雨天环境或晴天环境。具体的，本发明中的天气检测模块为雨量计8，雨量计8检测到每小时累计雨量大于2mm时则表示进入到了雨天环境。其中，用来衡量进入雨天环境的累计雨量数值可以根据当地水文条件选取。
污水检测模块用于检测井体1内的污染物的物理量。具体的，本发明中的污水检测模块为COD计9，也可以根据需要采用总氮计、总磷计等来检测水体污染物的物理量。
当天气检测模块检测为雨天环境时，雨天处理模块用于驱动第一水力开关3动作，使第一水力开关3达到第二高度Q2，使出水口12处于截流状态，防止流进进水口11的污水流进出水口12。本发明中的第二高度Q2可以取为2300mm，实际液位高度和第一水力开关3的高度应与现场的水文环境相关联选取。
雨天处理模块还用于判断井体1内的井内液位与第二高度Q2的高差是否大于等于临界值L，若是，则雨天处理模块控制第一水力开 关3动作至出水口12处于流通状态，并控制第二水力开关4关闭。若否，则污水检测模块进一步判断污染物的物理量与物理量下限M1和物理量上限M2的大小，若小于物理量下限M1，则雨天处理模块控制第一水力开关3动作至出水口12处于流通状态，并控制第二水力开关4关闭。若大于物理量上限M2，则雨天处理模块驱动第二水力开关4动作至出水口12处于截流状态。若位于物理量下限M1和物理量上限M2之间，则保持第一水力开关3和第二水力开关4现有状态。本发明中的临界值L可以取为100mm，当第二高度Q2取为2300mm，也就是指井内液位超过2400mm，M1取值为140，M2取值为160。
具体而言，可以分三种情况来说明：
1.若井内液位大于等于2400mm，即井体1内的井内液位与第二高度Q2的高差大于等于临界值L，表示有洪水来到井体1内，为不影响行洪安全，控制装置2控制第一水力开关3动作至出水口12处于流通状态，为防止污水进入河道，控制装置2控制第二水力开关4关闭。
2.如果井体1内的井内液位与第二高度Q2的高差小于临界值L，而COD计9检测到的COD值小于140，表示此时井内水体较好可以排入到河流或自然水体，此时控制装置2控制第一水力开关3动作至出水口12处于流通状态，为防止污水进入河道，控制装置2控制第二水力开关4关闭。
3.如果井体1内的井内液位与第二高度Q2的高差小于临界值L，且COD计9检测到的COD值大于160，表示水质不好，此时必须对污水进行截流到污水管内，使出水口12处于截流状态。若COD值位于140和160之间，则保持第一水力开关3和第二水力开关4现有状态。
与防倒灌模式类似，为了最大程度的将井内污水截污到污水管道，即当井内液位与污水液位的差值大于200mm时，应使第二水力开关4打开。为了防止污水倒灌进入井体1，当井内液位与污水液位的差值小于50mm时，应使第二水力开关4关闭。
(4)晴天模式：
晴天模式主要涉及到天气检测模块、污水检测模块、晴天处理模块。和雨天模式类似，雨量计8检测到每小时累计雨量小于0.6mm时则表示进入到了晴天环境。其中，用来衡量进入晴天环境的累计雨量数值可以根据当地水文条件选取。
当天气检测模块判断为晴天环境时，晴天处理模块用于驱动所述第一水力开关3动作，驱使第一水力开关3达到第二高度Q2，使出水口12处于截流状态，防止流进进水口11的污水流进出水口12，。
具体而言，晴天模式下井内污水是不能排到河道或自然水体的，所以此时必须把井内污水截流到污水管内。控制装置2控制第一水力开关3的高度到第二高度Q2，和防倒灌模式、雨天模式类似，为了最大程度的将井内污水截污到污水管道，即当井内液位与污水液位的差值大于200mm时，应使第二水力开关4打开。为了防止污水倒灌进入井体1，当井内液位与污水液位的差值小于50mm时，应使第二水力开关4关闭。
综上所述，本发明中的多功能分流井包括控制装置2，控制装置2包括停电处理模块、防倒灌控制模块、天气检测模块、污水检测模块、雨天处理模块和晴天处理模块。根据上述模块，控制装置2相应的具有停电模式、防倒灌模式、雨天模式和非雨天模式四个功能模式。从而能够很好的对在出现停电、倒灌等情形下进行相应的处理。改善了现有的分流井功能模式单一的问题。

控制装置2还包括晴天处理模块，控制方法还包括非雨天处理步骤，非雨天处理步骤包括：
当天气检测模块判断为晴天环境时，晴天处理模块驱动第一水力开关3动作，驱使第一水力开关3达到第二高度Q2，使出水口12处于截流状态。
