在微机工业控制中,因为输入数据不规则,使控制系统不能准确控制和显示。在我们实践中找到了用EPROM对输入数据进行处理的方法,可解决输入数据不规则的问题。举例说明如下: 1.起重机、启闭机的称重及过负荷保护装置起重机、启闭机的称重及过负荷保护装置是防止起重机倾翻,防止起重机、启闭机过负荷的重要手段,但在我们调试的数十台装置中能达到精度要求、能可靠工作的很少,究其原因主要是受机械特性(包括钢丝绳的特性)的影响以及传感器安装位置不恰当所致,传感器输出不能准确反映整机的受力状况,特别是上升与下降时称重的误差更大。很难用数学模型来准确
In the computer industrial control, because the input data is irregular, the control system can not accurately control and display. In our practice to find the use of EPROM input data processing methods to solve the input data irregularities. An example is as follows: 1. Crane, hoist weighing and overload protection device Crane, hoist weighing and overload protection device is to prevent the crane tipping over, to prevent cranes, hoist an important means of overload, However, we do not meet the accuracy requirements of dozens of devices we debug and can work reliably. The reason is mainly due to the influence of the mechanical characteristics (including the characteristics of the wire rope) and the improper installation of the sensor, and the sensor output can not Accurately reflect the machine’s stress conditions, especially when the rise and fall weighing error greater. It is difficult to use mathematical models to accurately
