沥青水泥砂浆的性能与其生产过程具有直接的关系。 当前, 为了获得 具有预定性能的沥青水泥砂浆, 主要用砂浆车制备沥青水泥砂浆, 砂浆车 通过适当的控制系统控制沥青水泥砂浆的成分和生产工艺流程, 以保证获 得具有预定性能的沥青水泥砂浆。
沥青水泥砂浆由多种组份形成的配方形成, 其配方的组份主要由乳化 沥青、 P乳剂、 水、 干粉、 1号添加剂、 2号添加剂及 3号添加剂这七种物 料。 根据具体应用要求的不同, 现在的沥青水泥砂浆垫板具有多种类型; 沥青水泥砂浆垫板有高弹模板、 低弹模板、 I型板和 II型板等多种型号; 各型号板具有不同的物料配方, 如高弹模板的配方中一般不含 P乳剂, 而 低弹模板的配方中一般使用 P乳剂。 当前, 为了保证沥青水泥砂浆填满预 定的间隙, 并保证获得的沥青水泥砂浆垫板具有预定的性能, 要求沥青水 泥砂浆进行生产时要具有计量精确的配方和合理的生产过程。 计量精确的 配方即要保证各组份含量的精确, 合理的生产过程即要保证各组份要以合 适顺序投放、 投放后要以适当的搅拌速度搅拌适当的时间。 为了实现计量 精确的配方和合理的生产过程, 一般在砂浆车上设置适当的控制系统, 通 过自动控制的方式控制配方的计量和生产过程, 获得具有预定性能的沥青 水泥砂浆。

下面结合附图对本发明进行详细描述, 本部分的描述仅是示范性和解 释性, 不应对本发明的保护范围有任何的限制作用。
请参考图 1 , 该图是本发明实施例一提供的砂浆车的控制系统的结构 框图。
实施例一提供的砂浆车的控制系统包括中央控制器 100、 电机控制器 200和 7个计量装置 300,本例中, 7个计量装置 300分别为 1#计量装置至 7#计量装置。 为了清楚起见, 图 1中还示出了 7个物料仓 500, 7个物料仓 500分别为 1#物料仓至 7#物料仓; 7个物料仓 500分别贮藏有乳化沥青、 P 乳剂、 水、 干粉、 1号添加剂、 2号添加剂和 3号添加剂 7种物料。 7个计 量装置 300分别与 7个物料仓 500——对应, 每个计量装置 300都能够从 其对应的物料仓 500上取出预定量的物料, 并将该物料通过其他机构或直 接投放到搅拌机构的搅拌筒中; 根据实际生产需要, 也可以使预定的一个 或多个计量装置 300包括储料机构; 这样, 在计时装置 300从相对应的物 料仓 500取出预定量的预定物料后, 可以先将取出的物料存放在储料机构 中, 然后再根据预定的策略,在预定的时刻将取出的物料投放到搅拌筒中。
中央控制器 100包括触发单元 110、存储单元 120、处理单元 130和取 料指示单元 140, 存储单元 120具有多个配方与生产工艺流程信息表和多 个分别与所述配方与生产工艺流程信息表相对应的最终搅拌参数。 每个配 方与生产工艺流程信息表和与其相对应的最终搅拌参数形成一个独立的信 息包, 该信息包与一种沥青水泥砂浆相对应, 包括该沥青水泥砂浆的精确 的配方信息和生产过程信息。 每个配方与生产工艺流程信息表中均包括预 定的多个参数, 本例中, 配方与生产工艺流程信息表包括预定数量的物料 参数, 和分别与所述物料参数对应的投料顺序参数。 本例中, 配方与生产 工艺流程信息表如下表所示:
Figure imgf000009_0001
每个配方与生产工艺流程信息表中包括 7种物料参数, 其中, 每个物 料参数又包括物料种类参数、 标记参数、 投放量参数、 搅拌时间参数和搅 拌速度参数。 其中, 物料种类参数分别表示 7种物料, 即分别表示 1#物料 至 7#物料。标记参数表示在该种沥青水泥砂浆生产过程中是否需要投放该 物料; 本例中, 以 1表示需要投放该物料, 以 0表示不投放该物料。 投放 量参数表示相对应物料的投放量, 投放量参数可以表示为 0投放量。 搅拌 时间参数和搅拌速度参数为投放相对应的物料后, 搅拌机构的搅拌时间段 和搅拌速度, 搅拌时间段根据预定沥青水泥砂浆性能确定, 搅拌速度参数 可以根据预定沥青水泥砂浆的性能和搅拌机构具体状况确定, 搅拌时间参 数可以表示搅拌时间为 0,也可以表示不为 0;搅拌速度参数可以有多种选 择, 一般三种选择就可以满足预定沥青水泥砂浆生产的需要。
触发单元 110能够根据输入的运行指令在存储单元 120中选择一个配 方与生产工艺流程信息表作为目标执行列表, 并产生触发信号; 另外, 还 能够根据电机控制器 200产生的运转完成信号产生触发信号, 触发信号可 以触发处理单元 130。
处理单元 130能够根据触发信号触发, 并根据目标执行列表中的标记 参数判断是否需要投料; 如果目标执行列表中标记参数的值全部为 0, 则 可以确定不需要投料, 判断结果为否, 表明物料已经投放完毕; 此时处理 单元 130能够根据与所述目标执行列表相对应的最终搅拌参数输出最终搅 拌指令; 如果标记参数至少一个为 1 , 判断结果为是, 此时, 处理单元 130 能够根据所述投料顺序参数选择物料参数, 并根据选择的物料参数向预定 的取料指示单元 140输出投料指令和搅拌指令, 处理单元 130也可综合投 料顺序参数和标记参数选择物料参数; 另外, 处理单元 130还能够根据取 料指示单元 140的取料完成信号和选择的物料参数输出延时指令。
所述取料指示单元 140根据投料指令选择预定的计量装置 300进行计 量操作; 投料指令包括物料种类信息和投放物料量信息, 这样, 取料指示 单元 140就可以根据物料种类信息选择并控制一个计量装置 300, 使该计 量装置 300根据投放物料量从与其相对应的物料仓 500中通过精确计量取 得预定量的物料;取料指示单元 140还可以监测计量装置 300的操作状态, 并在选择的计量装置 300完成计量操作时返回取料完成信号。 电机控制器 200能够根据搅拌指令和延时指令使搅拌电机 400按搅拌 指令进行预定运转操作, 搅拌指令可以包括搅拌速度信息, 延时指令可以 包括搅拌速度和搅拌时间; 这样, 在投料过程中, 电机控制器 200就可以 控制搅拌电机 400在以预定的搅拌速度运转; 在投料完成后, 电机控制器 转。 电机控制器 200还能够监测搅拌电机 400的运行操作, 并在搅拌电机 400完成运转操作时返回运转完成信号。
请参考图 2, 该图是本发明实施例一提供的砂浆车的控制系统的工作 过程示意图, 同时也是本发明提供的第一种砂浆车的控制方法的流程图。
S100, 触发单元 110根据输入的运行指令选择一个配方与生产工艺流 程信息表作为目标执行列表, 并产生触发信号; 触发单元 110可以为按鈕 或其他开关式装置。
S200, 处理单元 130根据触发信号触发, 根据目标执行列表中的标记 参数判断是否需要投料; 如果是, 则进入步骤 210; 如果否, 则进入步骤 220。处理单元 130根据标记参数判断的方法在对处理单元 130功能进行描 述时已经描述, 在此不再赘述。
S210, 处理单元 130根据投料顺序参数选择物料参数, 并根据选择的 物料参数输出投料指令和搅拌指令, 进入步骤 S300。
投料顺序参数根据沥青水泥砂浆的生产工艺流程确定, 处理单元 130 根据投料顺序参数确定各种物料投放的先后顺序, 并在该步骤中确定投放 物料的种类。 应当说明的是, 两种或多种物料可以同时投放, 因此, 可以 将同时投放的物料设置为相同的投料顺序参数。 投料指令根据选择的物料 参数确定, 因此, 投料指令可以包括物料种类信息、 投放物料量信息, 以 在下一步骤中执行预定的操作。 比如说, 可以选择与投料顺序参数值为 1 相对应的物料参数, 并根据该物料参数输出投料指令, 投料指令可以包括 以下信息: 物料种类为 1#物料, 投放量参数为 gl。
在输出投料指令的同时, 输出搅拌指令, 可以在投料过程中, 控制搅 拌机构处于运动状态, 保持沥青水泥砂浆具有预定的性能。 搅拌指令可以 包括搅拌速度信息, 如, 在投放 1#物料时, 搅拌指令可以包括搅拌速度为 vl的信息。
S220, 处理单元 130根据与配方与生产工艺流程信息表相对应的最终 搅拌参数输出最终搅拌指令, 进入步骤 S700。 在处理单元 130判断物料已 经投放完毕后, 沥青水泥砂浆的生产应当进入最后搅拌阶段, 最后搅拌阶 段是指所有物料投放后, 需要对形成的料浆进行总体搅拌, 因此, 处理单 元 130能够产生一个最终搅拌指令, 最终搅拌指令可以包括最终搅拌时间 和最终搅拌速度信息。
S300, 所述电机控制器 200根据所述搅拌指令控制搅拌电机 400进行 预定运转操作; 取料指示单元 140根据投料指令选择预定的计量装置 300 进行计量操作, 并在选择的计量装置 300完成计量操作时返回取料完成信 号。
电机控制器 200根据搅拌指令控制搅拌电机 400进行预定运转操作, 以在投料过程中, 保持搅拌机构处于运动状态, 保持沥青水泥砂浆具有预 定的性能。
取料指示单元 140能够对投料指令进行解析, 确定投放物料的种类及 该投放物料的投放量, 然后根据确定的投放物料的种类控制与该物料种类 相对应的计量装置 300进行计量操作, 并使计量装置 300根据确定的投放 量从相应的物料仓 500中取得预定量的物料,投放到搅拌机构的搅拌筒中。 比如, 在选择的物料种类为 1#物料, 投放量参数为 gl 时, 取料指示单元 140可以控制 1#计量装置 300,使 1#计量装置 300从 1#物料仓 500中获取 gl的 1#物料。 当然, 在投料指令包括同时投放两种物料时, 取料指示单元 140可以同时控制两个计量装置 300, 同时在两个物料仓 500取料。
取料指示单元 140可以采用适当的传感器实时监测计量装置 300计量 操作是否完成, 在计量操作完成时返回取料完成信号。
S400, 处理单元 130根据取料完成信号和选择的物料参数输出延时指 令, 同时, 修改与选择的物料参数相对应的标记参数。 在将预定物料投放 之后, 需要搅拌机构在预定的时间内持续地搅拌, 此时, 处理单元 130根 据取料完成信号和选择的物料参数输出延时指令, 延时指令可以包括延时 搅拌时间信息和搅拌速度信息; 在投放物料为 1#物料时, 延时指令可以包 括延时搅拌时间为 tl , 搅拌速度为 vl的信息。
修改与选择的物料参数相对应的标记参数的目的在于, 将该物料参数 标记为已投放, 以在下一循环中,将该物料参数与其他物料参数进行区分。 当然, 修改与选择的物料参数相对应的标记参数也可以在本次循环中其他 步骤中进行, 比如, 还可以在步骤 210中进行, 即在输出投料指令时, 修 改与选择的物料参数相对应的标记参数, 也能够达到同样的目的。
S500, 电机控制器 200根据延时指令控制搅拌电机 400进行预定运转 操作, 并在搅拌电机 400完成预定运转操作时返回运转完成信号。 电机控 制器 200可以根据延时搅拌时间信息和搅拌速度信息使搅拌电机 400在预 定时间内以预定的搅拌速度运转, 比如, 在投放 1#物料时, 可以使搅拌电 机 400在 tl时间内, 以 vl速度运转。 电机控制器 200也可以采用适当的 传感器实时监测搅拌电机 400的运行状态, 在搅拌电机 400完成预定运转 操作时返回运转完成信号; 也可以设置适当的计时装置, 在搅拌时间满足 预定条件时返回运转完成信号, 并使搅拌电机 400停止运转。
S600,触发单元 110根据运转完成信号产生触发信号,返回步骤 S200。 运转完成信号返回触发单元 110, 触发单元 110根据运转完成信号产生触 发信号, 以返回步骤 S200, 进入下一循环过程。
S700, 电机控制器 200根据最终搅拌指令控制搅拌电机 400运转。 电 机控制器 200解析最终搅拌指令, 获得包括最终搅拌时间信息和最终搅拌 速度信息, 并控制搅拌电机 400在预定的最终搅拌时间内以预定的最终搅 拌速度进行搅拌, 完成沥青水泥砂浆的生产。 电机控制器 200可以实时监 测搅拌电机 400的运转状态,并在完成最终搅拌指令后,产生预定的信号, 以提醒操作人员。
然后, 可以将配方与生产工艺流程信息表中的标记参数恢复初始值, 进行下一轮的生产过程
根据上述描述, 可以看出, 在需要生产预定类型的沥青水泥砂浆垫板 时, 可以输入预定的运行指令, 触发单元 110根据运行指令选择一个配方 与生产工艺流程信息表作为目标执行列表, 处理单元 130能够根据目标执 行列表的参数完成沥青水泥砂浆的生产, 获得预定性能的沥青水泥砂浆; 这样, 用一个控制系统, 一台砂浆车, 就可以进行多种沥青水泥砂浆的生 产, 从而提高砂浆车的标准化和通用化, 提高生产沥青水泥砂浆的效率, 满足实际作业的需要。
为满足更多需要, 还可以使存储单元 120中配方与生产工艺流程信息 表的参数和最终搅拌参数为可设定参数, 即存储单元 120为可读写装置, 这样, 在预置的配方与生产工艺流程信息表和最终搅拌参数不能满足实际 生产作业需要时, 可以对存储单元 120中的配方与生产工艺流程信息表的 物料参数、 投料顺序参数和与配方与生产工艺流程信息表相对应的最终搅 拌参数重新设定, 使其参数满足实际需要, 进而, 再根据上述过程进行沥 青水泥砂浆的生产, 获得具有预定性能的沥青水泥砂浆垫板。 进一步地, 也可以在存储单元 120中设置一个配方与生产工艺流程信息表和与该配方 与生产工艺流程信息表相对应的最终搅拌参数, 在实际生产中, 先根据实 际需要对各参数进行设定, 再进行相应的生产作业; 同样也能够提高砂浆 车的控制系统的通用性和生产效率。
另外, 处理单元 130也可以根据投料顺序参数确定是否需要投料, 在 存在不需要投放物料和需要投放物料时, 可以将与预定的不需要投放的物 料种类参数相对应的投料顺序参数设置为预定的值, 比如可以设置为 0, 并将与其他需要投放的物料种类参数相对应的投料顺序参数设定为不为 0 的其他值; 这样, 处理单元 130就可以根据投料顺序参数的值判断是否需 要投料。 此时, 可以将物料参数中的标记参数省去, 筒化配方与生产工艺 流程信息表的结构, 同时, 省略在输出投料指令或搅拌指令时, 修改与选 择的物料参数相对应的标记参数的操作。
由于沥青水泥砂浆性能的不同, 在生产中, 可能不需要投放预定种类 的物料, 一般来讲通过投料顺序参数的设定就可以避免物料投放错误, 为 了保证沥青水泥砂浆生产的可靠性, 在本发明实施例二提供的砂浆车的控 制系统中, 所述取料指示单元 140还能够根据投放量参数判断投放量是否 为 0, 如果是, 则直接返回取料完成信号, 如果否, 则选择预定的计量装 置 300进行计量操作, 并在所述计量装置 300完成预定的计量操作时返回 取料完成信号。 这样能够使生产工艺流程能够根据预定步骤进行, 并进一 步地避免在投放物料时产生错误。
请参考图 3 , 该图是本发明实施例二提供的砂浆车的控制系统的工作 过程示意图, 同时是本发明提供了第二种砂浆车的控制方法的流程图, 与 第一种砂浆车的控制方法的区别在于, 实施例二提供的砂浆车的控制方法 中, 其步骤 S300就包括以下步骤:
S310, 判断投放量是否为 0, 如果否, 则进入步骤 S320; 如果是, 则 进入步骤 S330。
S320, 选择预定的计量装置 300进行计量操作, 并确定选择的计量装 置 300是否完成预定的计量操作, 如果是则进入步骤 S330。 即在选择的计 量装置 300完成预定的计量操作时返回取料完成信号。
S330, 返回取料完成信号。
根据沥青水泥砂浆性能的不同, 在实际生产中, 投放预定种类的物料 后, 可能不需要启动搅拌电机 400进行搅拌, 为了满足这种要求, 并保持 控制系统的通用性能和具有较短的响应时间, 本发明实施例三提供的砂浆 车的控制系统中, 电机控制器 200还能够根据延时指令判断延时搅拌时间 是否为 0, 如果是, 则直接返回运转完成信号, 如果否, 则指令搅拌电机 400按延时指令进行预定运转操作, 并在搅拌电机 400完成预定运转操作 时返回运转完成信号。 这样, 就可以通设定延时搅拌时间, 使控制系统在 保持通用性的同时, 提高控制响应速度。
请参考图 4, 该图是本发明实施例三提供的砂浆车的控制系统的工作 过程示意图, 同时是本发明提供了第三种砂浆车的控制方法的流程图, 与 第一种砂浆车的控制方法的区别在于, 其步骤 S500包括以下步骤:
S510, 判断延时搅拌时间是否为 0, 如果否, 则进入步骤 S520; 如果 是, 则进入步骤 S530。
S520, 控制搅拌电机 400按延时指令进行预定运转操作, 并确定所述 在搅拌电机 400是否完成预定运转操作, 如果是则进入步骤 S530。 即在搅 拌电机 400完成预定运转操作时返回运转完成信号。
S530, 返回运转完成信号。
为了实现对搅拌速度的准确控制, 搅拌机构的搅拌电机 400可以是变 频电机, 以根据变频信号控制其转速, 使搅拌机构以预定的转速旋转, 保 证生产的沥青水泥砂浆具有预定的性能。 电机控制器 200可以还包括转换 单元和变频器, 转换单元根据搅拌指令、 延时指令或最终搅拌指令产生多 种变频信号,一般来讲三种变频信号就可以满足沥青水泥砂浆的生产需要; 变频器能够根据变频信号输出预定控制频率, 变频电机根据控制频率以预 定转速输出动力, 实现对搅拌电机 400搅拌速度的精确控制。 另外, 也可 以使电机控制器 200包括变频器, 并使搅拌指令、 延时指令或最终搅拌指 令包括变频信号, 变频器能够根据变频信号输出预定控制频率, 实现对搅 拌电机 400转速的精确控制。
可以理解, 在各物料相对应的投放量参数值相同, 或者通过计量装置
300设定各物料投放量参数时, 也可以将配方与生产工艺流程信息表中的 投放量参数省去; 同理, 在各物料相对应的搅拌时间参数值和 /或搅拌速度 参数值相同,或通过电机控制器 200设定搅拌时间参数和搅拌速度参数时, 也可以将配方与生产工艺流程信息表中的搅拌时间参数和 /或搅拌速度参 数省去。
在提供上述控制系统的基础上, 还提供了一种具有该控制系统的砂浆 车, 该砂浆车包括搅拌电机 400和多个物料仓 500, 每个物料仓 500用于 存放一种预定物料, 所述搅拌电机 400驱动搅拌机构运转, 还包括上述任 一种砂浆车的控制系统, 多个所述计量装置 300与多个物料仓 500——对 应, 所述电机控制器 200与搅拌电机 400相连。 由于砂浆机的控制系统具 有上述技术效果, 具有该控制系统的砂浆机也具有相对应的技术效果。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的 普通技术人员来说, 在不脱离本发明原理的前提下, 还可以做出若干改进 和润饰, 这些改进和润饰也应视为本发明的保护范围。
