摘要:
An engine protection system for a construction machine can individually diagnose the exhaust temperature specific to each cylinder of an engine corresponding to an engine revolution speed in order to find an abnormal condition of each engine cylinder in advance. A revolution speed sensor 14 detects revolution speed of an engine mounted in the construction machine and, a plurality, e.g., 16, cylinder temperature sensors 20a-20p detect exhaust temperatures of respective cylinders of the engine. A data recording unit 26 and a display controller 24 store the detected engine revolution speed and the detected exhaust temperatures of the respective cylinders. Trend data, which is produced based on the stored data, is sent to an office via a portable terminal and the display controller 24 outputs, a signal for playing back and displaying snapshots based on the stored data to a display unit 23 disposed in the cab 5.
摘要:
An information providing system for a construction machine has a plurality of information terminals (4) provided on the side of users or owners of hydraulic excavators (1), a main server (5) provided on the side of a manufacturer of the hydraulic excavators, and an intermediate server (6) provided on the side of a dealer in charge of services presented to the users or the owners. The main server (5) obtains data regarding machine operation of each hydraulic excavator (1) via information communication and stores the obtained data in a database (5A ), and outputs the obtained data regarding the machine operations of the plurality of hydraulic excavators (1), as basic information for services presented to the users or the owners, to the intermediate server (6). The intermediate server (6) outputs, to the corresponding information terminal (4), the basic information directly or after optionally selecting the basic information.
摘要:
An intermediate server 6 or a main server 5 executes the steps of displaying a work site of a construction machine or a predetermined area regarding the work site on a subcontractor's personal computer 62, prompting an input for applying to an order for work of repair/replacement of parts belonging to a predetermined component section of the construction machine, extracting the predetermined qualification requirements, which have been stored in a database 6A beforehand, from the database based on received applying information, producing an examination sheet for determining whether a local subcontractor meets the extracted qualification requirements, transmitting the examination sheet produced in the producing step to the subcontractor's personal computer 62 via a communication network, and prompting an input in predetermined places of the examination sheet. An information processing system and an information processing method for construction machines are provided which can present satisfactory services to the customer side even when the work site is in, e.g., a remote frontier region.
