A signal sending device 21 which stores therein proper data, such as an accelerator position and a pump output, concerning operating conditions, such as supply hydraulic pressure and flow rate, appropriate for a working attachment to be attached to the front part of a hydraulic excavator or the like is mounted on the working attachment. The body of a hydraulic excavator is provided with a controller 11 adapted to control the hydraulic sources by receiving and storing proper data sent from the signal sending device 21. The signal sending device 21 includes a ROM 31 for storing proper data for each working attachment, a CPU 32 for retrieving proper data from the ROM 31, and a data communication interface (COM) 33 for receiving command signals sent from the controller 11 of a machine body to the CPU 32 and sending to the controller 11 proper data which have been retrieved from ROM 31 by the CPU 32.
Dispositif de transmission de signal 21, stockant des données pertinentes, p. ex. des données de position d'accélérateur et de sortie de pompe, relatives aux conditions de fonctionnement, p. ex. pression hydraulique d'alimentation et débit, et adaptable à un équipement de travail fixé à l'avant d'une pelle hydraulique ou autre machine assimilée. Le corps d'une pelle hydraulique est doté d'un contrôleur 11 adapté pour commander les sources hydrauliques en recevant et en stockant des données pertinentes provenant du dispositif de transmission de signal 21. Le dispositif de transmission de signal 21 comprend un ROM 31 pour stocker les données pertinentes pour chaque équipement de travail, un CPU 32 pour extraire les données pertinentes de la ROM 31, et une interface de communication de données (COM) 33 pour recevoir des signaux de commande transmis par le contrôleur 11 d'un corps de machine au CPU 32 et envoyer au contrôleur les données pertinentes extraites de la ROM 31 par le CPU 32.
