Description

一种电子皮带秤的称量控制装置及其方法 技术领域
本发明涉及一种称量控制装置及其方法，尤其是一种适用于带式输送机连续输送物料在线监测的电子皮带秤的称量控制装置及其方法。
背景技术
目前，用于带式输送机连续输送物料称量的全悬浮承载器结构的电子皮带秤，多采用在一个承载器上设置4个称重传感器， 将4个称重传感器输出的称重信号并联成一路称重信号，然后与测速传感器输出的速度信号一起进行累积运算，并在累计器上显示运算结果的称量控制装置。
技术问题
这种结构形式的电子皮带秤的称量控制装置，由于4路称重信号并联成一路称重信号以后再与速度信号一起进行累积运算，这样当其中有一个传感器发生故障时，则整个皮带秤将计量不准，而且在运行过程中不易被发现，因此在输送物料过程中会由于计量的不准造成损失。
技术解决方案
本发明的目的是克服已有技术中的不足之处，提供一种电子皮带秤的称量控制装置及其方法，通过改变组合方式，能监测到某个称重传感器发生故障，并控制当某个称重传感器损坏时，电子皮带秤仍可进行准确计量。
为实现上述目的，本发明的称量控制装置，包括四个称重传感器支承的全悬浮称重承载器，位移传感器及累计器，所述的四个称重传感器的信号输出端分四路分别连接累计器，通过对累计器软件编程将四路称重信号组合为三组信号，形成对称重承载器进行一组全悬浮式主累计量和二组单杠杆式辅累计量的测重，所述的累计器由计算机或电子称重显示控制仪表构成。
所述的三组称重信号，一种组合为A、B、C、D称重传感器组合产生的主累计量，另外两种组合分别为A、B称重传感器组合产生的辅累计量以及C、D称重传感器组合产生的辅累计量。
本发明的称量控制方法：
a、通过处理器软件模块将接收到的四路称重信号组合为三组信号，一组为A1、B1、C1、D1四路全悬浮式主累计量信号，两组为A1、B1或C1、D1单杠杆式辅累计量信号，
b、检测A、B称重传感器组合产生的辅累计量与C、D称重传感器组合产生的辅累计量信号；
c、实时在线比对，
若上述两组辅累计量比对数值相差不大，在设定范围内，此时显示器显示值为A、B、C、D称重传感器组合产生的主累计量信号；
若上述两组辅累计量比对数值相差过大，不在设定范围内，则对两组内的称重传感器的输出信号分别进行比对，判断出有故障的称重传感器；
d、对A、B或C、D称重传感器组合产生的辅累计量超出设定范围的辅积算器报警，同时选择A、B或C、D称重传感器组合中无故障的一组辅累计量替代主累计量显示，以保证皮带秤在某一称重传感器有故障时仍可靠的进行称重。
 有益效果
本发明通过对四个称重传感器的输出进行三种不同的组合计算，得到三组累计量数值，累计器通过程序对其中二组累计量数值进行实时在线比对，判断某一称重传感器是否有故障，报警并显示称重传感器输出正常的一组累计量数值。从而保证即使某一称重传感器发生故障，电子皮带秤仍能可靠地进行称量。而此时不需要停机，设备仍可以继续可靠运行，待整个运行工作结束停机后，再进行故障传感器的更换，从而避免了由于工作中更换传感器需要对皮带秤重新标定所带来的各种损失。解决了在输送工作中由于传感器发生异常，造成计量不准，同时又不容易发现计量不准的难题。提高了皮带秤的可靠性和计量精确度，适用于带式输送机连续输送物料的在线精确可靠称重计量。其结构紧凑合理，可靠性高，计量精确，易维护，使用寿命长，具有广泛的实用性。

 本发明的实施方式
下面结合附图对本发明的实施例作进一步的描述：
图1及图2所示，本发明的称量控制装置，主要由A、B、C、D四个称重传感器1，一台由四个称重传感器1支承的全悬浮称重承载器6，一个位移传感器5及累计器4构成。其中称重传感器1为模拟信号传感器时，称重传感器1上连接有信号转换器2，如图1所示；称重传感器1为数字信号的传感器时，则不需要信号转换器2。累计器4主要包括处理器、整形器、存储器、显示器和电源，其中信号转换器2为24位模数转换电路AD7710，处理器为32位CPU集成电路S3C44B0X，存储器为集成电路39VF160，位移信号整形器为集成电路393，显示器为640×320点阵，电源为220V交流电。处理器包括称重信号比较器，与其相连的两个辅积算器3，连接在两个辅积算器3之间的积算器比较器。四个称重传感器1的信号输出端分四路分别连接累计器4，通过对累计器4软件编程将四路称重信号组合为三组信号，一种组合为A、B、C、D称重传感器1组合产生的主累计量，另外两种组合分别为A、B称重传感器1组合产生的辅累计量以及C、D称重传感器1组合产生的辅累计量，形成对称重承载器6进行一组全悬浮式主累计量和二组单杠杆式辅累计量的测重，通过累计器对称重承载器6的输出信号比对，完成实时在线比对、判定控制，当某一组信号出现异常时，累计器会及时判断控制并显示正常的累计量。累计器4亦可采用计算机，简化结构，通过软件编程来实现对称重承载器6的控制。
本发明的称量控制方法：采用设置在全悬浮称重承载器6上的四个称重传感器1，设置在电子皮带秤上的一个位移传感器5，连接由计算机或电子称重显示控制仪表构成的累计器4，通过处理器软件模块程序控制对四个称重传感器1的独立输出进行三种不同的组合计算，得到三种不同的组合计算结果，电子皮带秤称重承载器6通过称重传感器1不同组合形成一个全悬浮称重承载器和两个单杠杆式称重承载器6，从而产生三组累计量数值，将两个单杠杆式称重承载器产生的两组累计量数值进行实时在线比对，如此二组累计量数值相差不大，在设定值范围内，则认为称重传感器无故障，累计器4则显示一个由A、B、C、D四个称重传感器组成的全悬浮称重承载器6为结构主累计量；如此两组累计量数值相差过大，不在设定范围内，则进一步对各组内的称重传感器1的输出分别进行比较、判断某一称重传感器1是否有故障，通过累计器4显示称重传感器1输出正常的一组由单杠杆式称重承载器为结构的辅累计量，从而保证即使某一称重传感器发生故障，电子皮带秤仍能可靠地进行称量。
A、B、C、D四个称重传感器1的输出经信号转换器2（A、B、C、D四个称重传感器1的输出信号为数字信号时，则不需要经信号转换器2），形成A1、B1、C1、D1四路独立的信号进入处理器进行信号处理。位移传感器5输出的速度信号经整形器形成速度数字信号进入处理器进行信号处理。处理器中的软件模块两个辅积算器3分别对A1、B1和C1、D1两组称重信号和速度数字信号进行积算处理形成电子皮带秤的两个辅累计量；通过处理器中的软件模块积算器比较器将两个辅积算器3中的辅累计量实时进行比对、判定控制。正常工作情况下，由四个称重传感器1组成的全悬浮称重承载器6为结构累计量作为电子皮带秤的主累计量。当二者差值在要求的设定范围内时，处理器将主累计量送入显示器中进行显示；当二者的差值超出要求的设定范围时，处理器中的软件模块称重信号比较器对两个辅积算器3的两组称重信号A1、B1和C1、D1分别进行比较，当A1、B1信号的差值在要求的设定范围内时，处理器将A1、B1的辅积算器3的累计量送入显示器中进行显示，并对C1、D1的辅积算器3中的称重数字信号报警；上述情况中如果A1、B1信号的差值超过要求的设定范围内时，处理器则将C1、D1的辅积算器3的累计量送入显示器中进行显示，并对A1、B1的辅积算器3中的称重数字信号报警；相对以上情况，电子皮带秤在不作任何结构变化的情况下，而仅改变称重传感器1与称重承载器6的铰接点的功能就可以得到三种相应的组合型式。第一种型式全悬浮称重承载器6中A、B 、C、D四个称重传感器1与称重承载器6的铰接点均作为测力点，此时电子皮带秤组合变换形成一个全悬浮称重承载器6；第二种型式单杠杆式称重承载器6中A、B两个称重传感器1与称重承载器6的铰接点仅作为支点，而此时 C、D两个称重传感器1与称重承载器6的铰接点仍作为测力点，此时电子皮带秤组合变换形成一个以A、B两个称重传感器1与称重承载器6的铰接点作为支点，以C、D两个称重传感器1与称重承载器6的铰接点作为测力点的单杠杆式称重承载器6；第三种型式单杠杆式称重承载器6中A、B两个称重传感器1与称重承载器6的铰接点作为测力点，而此时 C、D两个称重传感器1与称重承载器6的铰接点作为支点，此时电子皮带秤组合变换形成一个以A、B两个称重传感器1与称重承载器6的铰接点作为测力点，以C、D两个称重传感器1与称重承载器6的铰接点作为支点的单杠杆式称重承载器6。在系统故障中只要两个辅积算器3中有一个正常，仍可以继续维持电子皮带秤系统的正常工作，此时的电子皮带秤组合变换形成单杠杆式称重承载器6，致使称重系统计量不中断，不需要停机，待正常停机后再更换称重传感器，从而避免了由于运行过程中需更换称重传感器对皮带秤重新标定所带来的损失，以及计量不准确造成的损失，解决了在输送工作中由于传感器发生异常，造成计量不准，同时又不容易发现计量不准的难题，从而提高了电子皮带秤系统使用的可靠性。
