产品介绍




视觉传感器计算出的误差,由PLC换算成机械的移动量,定下补正误差的位置并实行。
 
 
 
3.视觉传感器
  在这个控制里面,对提高精度较重要的一点就是视觉传感器的位置判别。如果视觉传感器无法精度较好的判别出位置,此控制里所讲到的提高精度也就无法达到了。我们的视觉传感器,从经验和技术上,对提高判别精度可实现以下的功能。  ●高精度Search
   判别出和所记忆的标记数据相似的部分,进行高精度的位置数据计算。
   在负载上印刷标记时,每次都印刷出同样的标记是比较困难的。会发生印刷的缺陷或是印刷不良等情况。但是,如果使用了此功能,
即使实际负载上所印刷的标签和登录的标签不同,也可以精度较好地进行判别。  ●ECM(Edge code model)Search
   把所记忆的标签边缘(非整个标签,只有四周一圈)作为典型进行登录,从实际接受到的画像数据中找出相似的部分进行判定。在玻璃互相重叠的情况下,会发生想判别的标签之间也重叠起来的例子。在此功能中,因是以标签边缘数据形式进行典型化登录的,即使发生了标签的重叠化,仍可以判别出四周一圈是何形状,从而达到高精度的判断。
 
 
4.校准
  视觉传感器中所识别的位置信息,会作为视觉传感器内部的画素数据进行判别。但是,此画素数据和实际的工作台的移动距离关系,如果没有明确,就无法实现负载的位置补正。
  所谓校准,就是把视觉传感器所识别到的位置和实际工作台的位置精度的关系明确化,并记住。
  我们把这个校准功能放在视觉传感器,PLC,伺服控制的程序上,以自动控制的方式进行实现。
  在登录负载的基准位置时,会实施如下所示的动作,终完成校准。
  实际移动负载时,可以通过演算当时的视觉传感器位置信息,达到对下列误差的补正。
● 摄像机安装误差:当摄像机的安装不是完全的垂直时,可以补正其误差。
● 机械工作台移动误差:补正由于加工精度而导致的移动量的误差。
● 机械工作台搭建误差:补正机械工作台驱动轴搭建时的误差。
 
 
 
5.移动补正计算
  后,需要用视觉传感器所判别出的位置补正量对工作台进行移动。
  需要注意的是,工作台的机构会根据现场案例而不同。
  这次所介绍的是针对于如下图的3系统的工作台构成,将其座标变换以PLC和伺服控制来完成。
  近几年,FPD行业的玻璃尺寸有变大的趋势,并增加了UVW工作台这样的构成。
  UVW工作台,具有大运动行程较小,旋转角度精度较高的特征。
  负载的大小(标记间的长度)变大后,由角度误差而引起的偏移量也会变大,对抑制此种误差是有效果的。
  而且,此种工作台的驱动轴是在1个平面上,与以前的XYθ驱动轴层状重叠相比较的话,是较轻薄的机构,具有重量变轻巧的特征。
  
The HMI is connected with the CP340 of PLC by RS232 interface and communicates with Siemens'3964R protocol. 3.3 The monitoring configuration of the power grid is based on the DIRIS m type electric quantity monitor of SOCOMEC company of France, which can detect the phase voltage, line voltage, phase current, zero line current, active and reactive power, power factor of three-phase four-wire system, frequency and corresponding maximum. The Monitor is connected with CP340 OF PLC by MODBUS protocol with RS485 interface, and transmits the monitoring data of power network. Because the pump station is using, two-way power grid into the line, so the application of two sets of power monitors, respectively installed on both sides of the line on the cabinet.The signals of other devices are connected to the PLC through digital or analog point-in and point-out. 4. The realization of software monitoring, the automatic monitoring system of Tangqiao pump station has two parts: PLC monitoring software and touch screen chart control software. Plc Monitoring, software consists of several modules. 4.1 system detection and fault processing module, system detection and processing of all input signals, according to the specific situation will make different responses. The signals processed are: the temperature and vibration of six pump motors; the state of the Inlet and outlet sluice gates; the liquid level of the water storage room; the Safety Against Fire and theft; the temperature of two power transformers; the rainfall; the working conditions of four power factor compensation cabinets; Power Network conditions (voltage under-voltage and over-voltage monitoring; three-phase current over-load monitoring; Phase Missing Monitoring; three-phase Unbalance Monitoring; Power Over-load Monitoring; power factor monitoring; electricity accumulation) ; sewage pond water level, etc. . The system fault is classified into three levels: the first level fault is defined as the highest level. When such a failure occurs, all control outputs are disabled. Sound and light alarm, record and print, display the fault type and solution on the display screen. only after troubleshooting, press the manual reset button after the system back to normal work. A secondary fault is defined as a secondary fault. When such a failure occurs, the control output of the failure point is disabled and the system is automatically adjusted to continue the current operation. Fault alarm and recovery of the same level of failure. The three-stage fault is defined at the lowest level. When such a failure occurs, only sound and light warning, without interruption of the current operation. Implement the related sound and light alarm and record according to the various faults in the system. At this moment touch-screen into the fault alarm screen, display the fault content, nature, location, time and solutions, and print. 4.2 the operation and treatment of the decontamination machine and the drainage pump, the pumping station has two decontamination machine, the system carries on the monitoring to the decontamination machine working condition. Fault Signal Location, two-stage Fault Alarm, by & Lt; System Fault Processing & GT; Module Processing. Light or turn off the light according to the signal status. It is also displayed on a touch-screen display. When the selection switch on the decontamination machine cabinet selects the remote control,
