Abstract
Storage of data which changes during the operation of a construction machine and processing of data can be performed at a low cost by using existing sensors and switches mounted on the construction machine. In an operation section of a controller, each level for indicating a content of a detection signal of each sensor or an instruction signal of a switch is determined first. Then, the detection signal to be input is judged to belong to which of the respective levels at every sensor readout interval (sampling time), and a count value of the level to which the detection signal was judged to belong is processed to add for a portion of the sampling time. And, a time count value at every level stored in a storage section is read from the outside to perform the data processing.
