Description

派送处理方法及系统 技术领域
本发明实施例涉及物料派送领域，具体而言，涉及一种派送处理方法及系统。
背景技术
工厂内各工序的生产节拍不同、同一工序里各设备的生产节拍也不同，为了保证整厂的生产节拍一致，因此各工序设备需要搬入或搬出的载具数量不同。目前，常见的工厂内的制造执行系统(通过信息的传递，对从订单下达开始到产品完成的产品生成过程进行管理)一次性只发一个载具的搬运指令给自动化物料搬送系统(Automatic Material Handling System，AMHS)，具体地，制造执行系统根据联机设备控制系统(Inline Equipment Control System，LCS)转发的设备进料口的请求信号进行筛选，只筛选出一个载具，通过派送控制系统(Dispatch Control System，DCS)下发控制命令给自动化物料搬送系统，自动化物料搬送系统控制自动导引运输车(Automated Guided Vehicle，AGV)一次性只搬运一个载具到设备(Equipment，EQ)的进料口或从设备出料口只搬运一个载具。
然而，设备生产节拍比较快，AGV搬运速度相对较慢，如果按照传统的一次只能运输一个载具进行设计，会造成产品搬送速度跟不上生产节拍，会导致设备间隔性地停产，导致设备产能较低。
针对上述的问题，目前尚未提出有效的解决方案。

下面，如图2(a)所示，对本实施例的派送处理系统的派送处理流程进行描述，其中，图2(a)具体为投料处理流程：
步骤a，EQ发送Load Request、载具数量(n)、Port ID。
步骤b，LCS发送Load Request、载具数量(n)、Port ID。
在有U型Port的设备端(即图2(a)中的EQ)可设置投料口需要投入的载具数量，将Load Request信号(即上述的投料请求信号)、载具数量(即上述的待运输载具的数量)、Port ID(即上述的投料口标识)一起通过LCS(Inline Equipment Control System，联机设备控制系统)上报给MES(Manufacturing Execute System，制造执行系统)。
步骤c，MES下发多载具派送指令。
MES知道设备投料口需要的载具数量后，会根据实际情况与DCS联动，将需要下 发多载具派送指令的载具信息(载具ID，搬送来源位置，搬送目的位置等)通过DCS下发给AMHS。
步骤d，AMHS下发内部调度指令。
AMHS会下发内部调度指令控制AGV将设备(即EQ)需要的载具装载完成后移动到设备投料口处等待。
设备和AGV之间会进行信号确认，设备也会将需要的载具数量告诉AGV，AGV会将车上的载具数量进行核对，如两边数量一致，进行传输载具动作；如数量不一致，则AGV会返回信号告知设备，具体逻辑说明如下：
设备需要的载具数量(n)与AGV上的载具数量(k)关系如下：
当n＝k时,AGV返回信息数量一致信号给设备，AGV可以将载具放到设备投料口；
当n>k时,AGV返回信息数量不一致信号给设备，设备会发出报警，只要k不等于0，AGV依然可以将载具放到设备投料口，但只能投入k个载具。
n<k,AGV返回信息数量不一致信号给设备，设备会发出报警，只要n不等于0，AGV依然可以将设备需要的载具放到设备投料口，但只能投入n个载具。
步骤e，AGV将多个载具搬运到EQ投料口处等待。
步骤f，EQ发送Load Request、载具数量(n)。
步骤g，AGV将第一个载具搬运到EQ投料口。
步骤h，第一个载具离开投料口进入设备内部。
步骤i，EQ发送Load Complete、载具ID、Port ID。
LCS将Load Complete、载具ID、Port ID转发给MES。
步骤j，EQ发送Load Request、载具数量(n-1)。
步骤k，AGV将第二个载具搬运到EQ投料口。
步骤l，第二个载具离开投料口进入设备内部。
步骤m，EQ发送Load Complete、载具ID、Port ID。
LCS将Load Complete、载具ID、Port ID转发给MES。
步骤n，EQ发送Load Request、载具数量(n-2)。
步骤o，AGV将最后一个载具搬运到EQ投料口。
步骤p，最后一个载具离开投料口进入设备内部。
步骤q，EQ发送Load Complete、载具数量(0)。
步骤r，EQ发送Load Complete、载具ID、Port ID。
LCS将Load Complete、载具ID、Port ID转发给MES。
步骤s，port上无载具，进入下一个循环。
下面，如图2(b)所示，对本实施例的派送处理系统的派送处理流程进行描述，其中，图2(b)具体为出料处理流程：
步骤A，EQ发送Load Request、载具数量(n)、Port ID。
Port上有载具，U型Port的设备端(即图2(b)中的EQ)发送需要退出的载具数量n。
步骤B，LCS发送Load Request、载具数量(n)、Port ID。
步骤C，MES下发多载具派送指令。
MES知道设备出料口需要退出的载具数量后，会根据实际情况与DCS联动，将需要下发多载具派送指令的载具信息(载具ID，搬送来源位置，搬送目的位置等)通过DCS下发给AMHS。
步骤D，AMHS下发内部调度指令。
AMHS会下发内部调度指令控制AGV移动到设备出料口处等待。
步骤E，AGV移动到EQ出料口处等待。
步骤F，第一个载具到达出料口可以退走。
步骤G，EQ发送Load Request、载具数量(n-0)。
步骤H，AGV将第一个载具从EQ出料口搬运到车上。
步骤I，EQ发送Load Complete、载具ID、Port ID。
LCS将Load Complete、载具ID、Port ID转发给MES。
步骤J，第二个载具到达出料口可以退走。
步骤K，EQ发送Load Request、载具数量(n-1)。
步骤L，AGV将第二个载具从EQ出料口搬运到车上。
步骤M，EQ发送Load Complete、载具ID、Port ID。
LCS将Load Complete、载具ID、Port ID转发给MES。
步骤N，最后一个载具到达出料口可以退走。
步骤O，EQ发送Load Request、载具数量(1)。
步骤P，EQ发送Load Complete、载具ID、Port ID。
LCS将Load Complete、载具ID、Port ID转发给MES。
步骤Q，EQ发送Load Complete、载具数量(0)。
步骤R，AGV将最后一个载具从EQ出料口搬运到车上，AGV移动到指定目的地。
步骤S，Port有下一批载具要退走，进入下一个循环。
在有U型Port的设备端可设置出料口需要搬走的载具数量，将Unload Request信号和载具数量一起通过LCS上报给MES系统。MES系统知道设备出料口需要的载具数量后，会根据实际情况与DCS系统联动，将需要下发派送指令的载具信息(载具数量，搬送来源位置，搬送目的位置等)通过DCS系统下发给AMHS系统。
AMHS系统会下发内部调度指令控制AGV移动到设备出料口处等待。
设备和AGV之间会进行信号确认，设备也会将需要搬走的载具数量告诉AGV，AGV会将自身收到的载具数量进行核对，如两边数量一致，进行传输载具动作；如数量不一致，则AGV会返回信号告知设备，具体逻辑说明如下：
设备需要搬走的载具数量(n)与AGV收到需要搬走的载具数量(k)关系如下：
当n＝k时,AGV返回信息数量一致信号给设备，AGV可以将载具从设备出料口搬走；
当n>k时,AGV返回信息数量不一致信号给设备，设备会发出报警，只要k不等于0，AGV依然可以将载具放从设备出料口搬走，但只能搬走k个载具。
n<k,AGV返回信息数量不一致信号给设备，设备会发出报警，只要n不等于0，AGV依然可以将设备需要搬走的载具从设备出料口搬走，但只能搬走n个载具。
在本发明实施例中，通过设备将请求载具数量上报至制造执行系统，制造执行系统生成相应的多载具派送指令，自动化物料搬送系统根据所述多载具派送指令将派送载具移动至所述设备处，并根据请求载具数量及派送载具数量进行载具运输，达到了 一次搬送多个载具的目的，从而实现了提高设备产能的技术效果，进而解决了由于现有技术一次只能运输一个载具进而造成设备产能较低的技术问题。
实施例2
根据本发明实施例，提供了一种派送处理方法的方法实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图3是根据本发明实施例的派送处理方法，如图3所示，该方法包括如下步骤：
步骤S302，制造执行系统接收设备发送的第一请求信号。
其中，所述第一请求信号携带有请求载具数量及设备标识。
步骤S304，根据所述请求载具数量及所述设备标识生成多载具派送指令。
其中，所述多载具派送指令包含派送载具数量及派送载具的参数信息。
步骤S306，将所述多载具派送指令发送至自动化物料搬送系统。
其中，由所述自动化物料搬送系统根据所述多载具派送指令将派送载具移动至所述设备处，并根据所述请求载具数量及所述派送载具数量进行载具运输。
下面，从MES的角度，分为进料口、出料口两个方面，对本实施例的派送处理方法进行说明：
根据收到的设备进料口的Load Request信号和载具数量进行筛选，将符合条件的载具通过DCS系统下发控制指令给AMHS，控制AGV一次只运输多个载具到设备进料口；如筛选出的符合要求的载具数量少于设备请求的载具数量，会自动下发消息告知设备，但依然会通过DCS发下控制指令给AMHS,控制AGV一次只运输多个载具到设备进料口。例如：设备请求要6个载具，但MES筛选只有2个载具符合要求，依然会通过DCS下发2个载具的搬运指令,AGV会搬运2个载具到设备进料口。
根据收到的设备出料口的Unload Request信号和载具数量,通过DCS系统下发控制指令给AMHS，控制AGV移动到设备出料口；如判断AGV载具容量少于等于设备卸载请求的载具数量，会通过DCS发下多次控制指令给AMHS,控制多台AGV分批次到设备出料口。例如：设备请求要搬出6个载具，但AGV一次只能运输5个载具，依然会通过DCS下发第一次搬运指令,AGV会到设备出料口先将前5个载具搬走；再通过DCS下 发第二次搬运指令给另外一台AGV，第二台AGV会到设备出料口再将第6个载具搬走。
图4是根据本发明实施例的派送处理方法，如图4所示，该方法包括如下步骤：
步骤S402，设备将第一请求信号发送至制造执行系统。
所述第一请求信号携带有请求载具数量及设备标识；其中，由所述制造执行系统根据所述请求载具数量及所述设备标识生成多载具派送指令，所述多载具派送指令包含派送载具数量及派送载具的参数信息；所述制造执行系统将所述多载具派送指令发送至自动化物料搬送系统，其中，由所述自动化物料搬送系统根据所述多载具派送指令将派送载具移动至所述设备处，并根据所述请求载具数量及所述派送载具数量进行载具运输。
下面，从设备的角度，分为进料口、出料口两个方面，对本实施例的派送处理方法进行说明：
在设备操作界面上可以分别设置投料口或出料口需要AGV一次搬运的载具数量(如表1)，以保证生产不中断。

b)AGV将第一个载具放到Port上后，设备发出LDCM(Load Complete)信号；
c)第一个载具离开Port进入设备内部后，设备保持LDCM(Load Complete)信号；
d)AGV将第二个载具放到Port上后，设备保持LDCM(Load Complete)信号；

f)设备可根据载具缓存数量提前发出UDRQ(Unload Request)信号，MES/DCS会通过AMHS通知AGV到Port口等待。
图5是根据本发明实施例的派送处理方法，如图5所示，该方法包括如下步骤：
步骤S502，联机设备控制系统将来自设备的第一请求信号发送至制造执行系统。
所述第一请求信号携带有请求载具数量及设备标识；其中，由所述制造执行系统根据所述请求载具数量及所述设备标识生成多载具派送指令，所述多载具派送指令包含派送载具数量及派送载具的参数信息；所述制造执行系统将所述多载具派送指令发送至自动化物料搬送系统，其中，由所述自动化物料搬送系统根据所述多载具派送指令将派送载具移动至所述设备处，并根据所述请求载具数量及所述派送载具数量进行载具运输。
步骤S504，在所述设备再次发出所述第一请求信号时，判断前一批载具是否运输完成。
步骤S506，如果未完成，则不再发送第一请求信号发送至所述制造执行系统，并输出错误信息。
下面，从LCS的角度，分为进料口、出料口两个方面，对本实施例的派送处理方 法进行说明：
(1)进料口：
根据设备进料口上报的Load Request时的载具数量,LCS将Load Request和载具数量发送给MES，MES会通过DCS下派送指令通知AGV搬运一批载具到设备进料口。LCS判断设备请求要搬入的载具数量(m)与发出请求的载具数量(n)是否一致。如n＝m,表示设备搬入此批载具动作已经完成，AGV可以离开设备进料口。如:n≠m,即使进料口是空的，设备发出搬入下一批待生产的产品载具的请求，LCS不会发信息(Load Request+载具数量)给MES,同时会发出错误信息给设备以及自身界面，提示人员介入处理。
(2)出料口：
根据设备出料口上报的Unload Request时的载具数量,LCS将Unload Request和载具数量发送给MES，MES会通过DCS下派送指令通知AGV到设备进料口。LCS判断设备请求要搬出的载具数量(m)与发出请求的载具数量(n)是否一致。如n＝m，表示AGV搬出此批载具动作已经完成，AGV可以离开设备进料口。如:n≠m,即使出料口是空的，设备发出搬出下一批生产完成的产品载具的请求，LCS不会发信息(Unload Request+载具数量)给MES,同时会发出错误信息给设备以及自身界面，提示人员介入处理。
通过上述步骤，通过设备将请求载具数量上报至制造执行系统，制造执行系统生成相应的多载具派送指令，自动化物料搬送系统根据所述多载具派送指令将派送载具移动至所述设备处，并根据请求载具数量及派送载具数量进行载具运输，达到了一次搬送多个载具的目的，从而实现了提高设备产能的技术效果，进而解决了由于现有技术一次只能运输一个载具进而造成设备产能较低的技术问题。
