    摘要: A control system for operating two engines (3, 4) is installed on a construction machine, such as a hydraulic shovel, to provide for the operation of either engine or both of the engines, to improve operability and to reduce the stress on the operator. The control system has a governor controller (5, 6) for each engine, a dial potentiometer (1) for providing a throttle signal representing the desired revolution rates of the engines from a low speed to a high speed, and a selector switch (2) having a plurality of control positions (F, N and R) for selecting an individual engine or a combination of the engines. In a first control position (F), the selector switch (2) connects the dial potentiometer (1) to only the governor controller (5) of the first engine (3); in the second control position (N), the selector switch (2) connects the dial potentiometer (1) to the governor controllers (5 and 6) of both engines (3 and 4); and in the third control position (R), the selector switch (2) connects the dial potentiometer (1) to only the governor controller (6) of the second engine (3). The selector switch circuit can employ a relay (Re) to actuate relay switches (Re.sub.1, Re.sub.2) to provide the desired switching.

    摘要: Only snapshot data necessary for monitoring faults are collected from machine such as vehicles, allowing faults to be more accurately monitored, and the amount of data and the memory storage volume at a monitoring station to be reduced. The values of a plurality of (A), (B), (C), and (D) operating parameters (engine rotational speed, lever operating position, vehicle speed, and tractive force) which change during the operation of the machine are sequentially detected for each machine. The fault detection history data are thus updated every time a fault (drop in engine oil pressure, overheating) is detected during the operation of the machine. Thus, when a fault (drop in engine oil pressure) is detected during the operation of the machine, it is determined on the basis of the history data whether or not to send to the monitoring station the sequential values of the operating parameters ((A) engine rotational speed, (B) lever operating position, (C) vehicle speed, (D) tractive force) from within a prescribed period of time (from 10 min. before to 5 min. after) around the point in time t0 at which the fault was detected. When it is determined that they should be sent, the type of detected fault (0001 (drop in engine oil pressure)), the values detected ((A) 2, (B) 3, (C) 3, (D) 2) at the time the fault was detected, as well as the sequential values of the operating parameters from within a prescribed period of time (from 10 min. before to 5 min. after) around the time the fault was detected are transmitted to the monitoring station. When it is determined that they should not be sent, on the other hand, the type of detected fault (0001 (drop in engine oil pressure)) and the values detected ((A) 2, (B) 3, (C) 3, (D) 2) at the time the fault was detected are sent to the monitoring station.
