发明名称 ELECTRONIC CONTROL SYSTEM OF CONSTRUCTION MACHINERY
摘要 <p>A system having a monitoring function in addition to a control function is able to suppress an increase in the amount of data communication and the communication frequency via a common communication line, and is flexibly adaptable for addition of a new function without causing mutual interference between control data and monitor data. A hydraulic excavator 1 includes a first control unit 17 for a prime mover 14, a second control unit 23 for a hydraulic pump 18, a third control unit 33 for control valves 24, 25 and 26, and first and second monitor units 45, 46. A first common communication line 39 for control and a second common communication line 40 for monitoring are further provided as common buses for data communication. The control units 17, 23 and 33 are interconnected via the first common communication line 39 for transmitting and receiving signals necessary for control among them, and the monitor units 45, 46 and the first control unit 17 are interconnected via the second common communication line 40 for transmitting and receiving signals necessary for monitoring among them.</p>
