摘要： A data processing unit for a construction machine, the unit being capable of storing the load condition of an engine independently of variations in engine output torque without entailing increases in cost due to additional installation of sensors. This data processing unit is designed such that the rotational speed of the engine when no load is imposed thereon and the actual rotational speed of the engine are detected; combinations of first parameter values and second parameter values are divided into a plurality of regions thereby setting a load map, the first parameter values being the values of the rotational speed of the engine when no load is imposed thereon while the second parameter values are the values of the difference between the rotational speed of the engine when no load is imposed thereon and the actual speed of the engine; detecting time of the first parameter value and the second parameter value of each region in the load map until a certain time elapses is accumulated; and the result of the accumulation for each region of the load map is stored.
摘要翻译：一种用于建筑机械的数据处理单元，该单元能够独立于发动机输出扭矩的变化来存储发动机的负载状况，而不需要由于附加安装传感器而导致的成本增加。该数据处理单元被设计成使得当不施加负载时发动机的转速和发动机的实际转速被检测到; 第一参数值和第二参数值的组合被划分为多个区域，从而设置负载图，第一参数值是当无负载施加时发动机的转速的值，而第二参数值是值在不施加负载的情况下发动机的转速与发动机的实际速度之差; 检测负载图中的每个区域的第一参数值和第二参数值的时间，直到经过一定时间; 并且存储负载图的每个区域的累积结果。
