Description

混凝土搅拌站及其质量监控系统
本申请要求于 2012 年 01 月 09 日提交中国专利局、 申请号为 201220006738.5 发明名称为"混凝土搅拌站及其质量监控系统"的中国专 利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉混凝土搅拌站技术领域, 特别涉及一种混凝土搅拌站质量监 控系统。此外,本发明还涉及一种包括上述质量监控系统的混凝土搅拌站。 背景技术
混凝土搅拌站主要用于工程建设, 其生产的混凝土质量直接关系到建 筑物的质量, 因此对搅拌站生产出来的混凝土质量进行有效管控就具备了 必需性。混凝土的质量主要是通过合成混凝土的各种物料的配合比来实现, 这就让混凝土质量的监控具备了可行性。
目前, 对于混凝土搅拌站生产的混凝土质量监测的方式一般有以下两 种:
第一种, 通过监控比较搅拌站控制系统数据库中保存的混凝土的各种 物料标注值及理论上或国家、 地方标准中规定的各物料值进行监控。
第二种, 通过施工方监理或施工方的来料检验进行监控, 或通过搅拌 站自身实验室进行塌落度的试验来监控质量。
对于上述第一种方式, 从搅拌站控制系统数据库中读取现有数据然后 上传给监控中心。 众所周知, 数据库中的数据很容易被修改, 因此无法保 证上传到监控中心数据的真实性, 造成监控系统没有起到应有的作用。
对于上述第二种方式, 不管是搅拌站自身实验室的塌落度试验还是施 工方的来料检验, 都存在人为因素, 且效率不高, 也容易出现作假现象, 因而无法完全保证最终用到建筑物上的混凝土的质量。
有签于此, 如何研发一种混凝土搅拌站质量监控系统, 该质量监控系 统能够减少监控过程中的人为因素,从而能够保证监控的准确性和可靠性, 是本领域技术人员亟需解决的问题。

在现有技术的基础上, 本发明所提供的混凝土搅拌站质量监控系统包 括采集单元、 下载单元和计算单元; 工作时, 采集单元与混凝土搅拌站的 物料称量传感器连接用以采集实际物料值, 并发出实际重量信号, 下载单 元与混凝土搅拌站的控制系统中的数据库连接用以下载标准物料值, 并发 出标准重量信号的下载单元; 所述计算单元分别与所述采集单元和所述下 载单元连接用以接收所述实际重量信号和所述标准重量信号, 当所述实际 物料值与所述标准物料值的差值的绝对值大于或等于预定值时发出报警信 号。

附图说明
图 1为本发明一种实施例中混凝土搅拌站质量监控系统的逻辑控制框 图;
图 2为本发明另一种实施例中混凝土搅拌站质量监控系统的逻辑控制 框图。
具体实施方式
本发明的核心为提供一种混凝土搅拌站质量监控系统, 该质量监控系 统的结构设计能够减少监控过程中的人为因素, 从而能够保证混凝土质量 监控的准确性和可靠性。 此外, 本发明另一个核心为提供一种包括该质量 监控系统的混凝土搅拌站。 为了使本领域的技术人员更好地理解本发明的技术方案, 下面结合附 图和具体实施例对本发明作进一步的详细说明。
请参考图 1 , 图 1为本发明一种实施例中混凝土搅拌站质量监控系统 的逻辑控制框图。
在一种实施例中, 本发明所提供的混凝土搅拌站质量监控系统, 用于 监控混凝土搅拌站生产的混凝土质量; 如图 1所示, 该质量监控系统包括 采集单元 2和下载单元 3 , 采集单元 2与混凝土搅拌站的物料称量传感器 11连接用以采集实际物料值, 并发出实际重量信号的采集单元 2; 下载单 元 3及与混凝土搅拌站的控制系统的数据库 12连接用以下载标准物料值, 并发出标准重量信号; 具体地, 混凝土搅拌站的控制系统的数据库 12设有 信息接口, 该下载单元 3可以通过该信息接口引出标准重量信号。
如图 1所示, 质量监控系统还包括计算单元 4, 计算单元 4分别与采 集单元 2和下载单元 3连接用以接收实际重量信号和标准重量信号, 并当 实际物料值与标准物料值的差值的绝对值大于或等于预定值时发出报警信 号。
在上述结构中,由于采集单元 2直接与物料称量传感器 11连接从而获 得实际物料值, 亦即从数据源头上获得实际物料值, 该实际物料值真实可 靠, 不会被人为地墓改。 综上, 本发明所提供的质量监控系统的结构设计 能够减少监控过程中的人为因素, 从而能够保证混凝土质量监控的准确性 和可靠性。
需要说明的是, 混凝土除了关键物料如水泥之外, 还涉及到其他多种 物料, 因而上述采集单元 2既可以与水泥称量传感器连接, 从而监控混凝 土中水泥的含量是否符合标准; 当然, 也可以与其他物料的称量传感器连 接从而监控混凝土中其他物料的含量是否符合标准。
此外, 举例说明上述预定值的含义: 比如, 每盘混凝土的标准物料值 为 10, 如果该预定值为 2, 则意味着当实际物料值小于等于 8或大于等于 12时, 混凝土中该种物料的含量不合格, 该监控系统会发出报警信号; 当 实际物料值大于 8并小于 12时, 混凝土中该种物料的含量合格,该质量监 控系统不发出报警信号。
在上述实施例中, 还可以做出进一步改进。 比如, 如图 1所示, 该质 量监控系统还包括信号处理单元 5 , 该信号处理单元 5与采集单元 2连接, 用以对实际重量信号进行消除偏差处理, 从而进一步确保了获得的实际物 料值的准确性。
再者, 在上述实施例中, 还可以做出进一步改进。 比如, 如图 1所示, 质量监控系统还包括存储单元 6, 该存储单元 6与计算单元 4连接, 用以 存储实际物料值和理论物料值, 从而实现数据的存储, 以方便相关人员查 阅。
在上述任一种技术方案中, 还可以做出进一步改进。 比如, 如图 1所 示, 质量监控系统还包括监控中心 7, 该监控中心 7与计算单元 4连接用 于接收其发出的报警信号。 当监控中心 7接收到报警信号后, 监控中心 7 的工作人员便可以采用相关措施, 比如暂停施工工地上混凝土的生产以进 行整改, 从而确保混凝土的生产质量符合要求。
进一步地, 如图 1所示, 计算单元 4与监控中心 7之间可以进一步通 过传输单元 8进行连接, 计算单元 4发出的报警信号可以通过该传输单元 8发送到监控中心 7,传输单元 8可以通过有线或无线的方式实现报警信号 的传输。 此外, 需要说明的是, 存储单元 6实时记录每盘混凝土实际物料 值、 标注物料值、 合同号及单号等数据, 从而用以支持传输单元 8的断点 续传功能。 需要说明的是, 传输单元 8中设有心跳信号, 当传输单元 8正 常工作时, 监控中心 7能够接收到该心跳信号, 当传输单元 8被人为拆除 时, 该心跳信号中断, 由此可提示监控中心 7采取相关措施。
在上述任一种技术方案中, 还可以做出进一步改进, 从而得到本发明 的另一种实施例。 具体地, 请参考图 2, 图 2为本发明另一种实施例中混 凝土搅拌站质量监控系统的逻辑控制框图。
在该实施例中, 如图 2所示, 采集单元 2还设有预警模块 21 , 预警模 块 21与传输单元 8连接, 当采集单元 2与物料称量传感器 11断开连接后 预警模块 21通过该传输单元 8向监控中心 7发出预警信号。 该预警模块 21设置的用于防止采集单元 2被人为地拆除;当采集单元 2被人为拆除时, 亦即采集单元 2与物料称量传感器 11之间的连接断开,采集单元 2无法采 集实际物料信号,此时预警模块 21便向监控中心 7发出预警信号, 以提示 监控中心 7的工作人员质量监控系统已被拆除, 因而需要采取相关措施。 进一步地, 如图 2所示, 采集单元 2还设有驱动模块 22, 该驱动模块 22与预警模块 21连接并接收其预警信号, 驱动模块 22进一步与混凝土搅 拌站的控制物料门开关的电磁阀 13连接, 以便驱动模块 22根据预警信号 向电磁阀 13 发出停止动作的指令。 在该种结构设计中, 一旦采集单元 2 被人为拆除, 驱动模块 22便控制电磁阀 13停止动作, 使得物料门无法打 开或关闭, 从而使得混凝土搅拌站不能工作。 显然, 该种结构设计能够防 止采集单元 2被认为拆除。
需要说明的是,如图 1所示,采集单元 2还包括采集模块 23和传输模 块 24, 采集模块 23与物料称量传感器 11连接, 用以采集实际重量信号的 采集模块 23; 传输模块 24及与采集模块 23连接, 用以传输其实际重量信 号的传输模块 24; 传输模块 24还与计算单元 4连接, 以便向其传输实际 重量信号。
此外, 本发明还提供一种混凝土搅拌站, 包括物料称量传感器 11 ; 混 凝土搅拌站还包括上述任一种技术方案中的混凝土搅拌站质量监控系统, 采集单元 2与物料称量传感器 11连接。 混凝土搅拌站的其他部分,可以参 照现有技术, 本文不再展开。
以上对本发明所提供混凝土搅拌站及其质量监控系统进行了详细介 实施例的说明只是用于帮助理解本发明的方法及其核心思想。 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 可以对本发明进行若干改进和修饰, 这些改进和修饰也落入本发明权利要 求的保护范围内。
