Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control means for specifying a model to be controlled based on model setting information set by the model setting means, and for executing control corresponding to the specified model. The present invention relates to a control device for a working machine provided.

[0002]

2. Description of the Related Art For example, in a control device for a working machine such as a combine machine such as a combine machine or a construction machine, a single control unit (a circuit board or a microcomputer) is configured to be compatible with all models of a series. Etc. are usually shared, but in this case, in order to perform control suitable for the model in which the control unit is mounted, it is necessary to specify the model.
Conventionally, the model setting means is configured by a DIP switch or the like that generates model information as a voltage on / off signal, or a harness that is connected to the control unit so as to input the on / off signal.

[0003]

However, in the above-mentioned prior art, if the number of contacts of the DIP switch increases with the increase in the number of models and the number of connection points of the harness increases, the voltage setting of each contact of the DIP switch may be erroneous. However, there is a possibility that a correct model setting information may not be input to the control unit due to a contact failure or the like at the connection point of the harness. The present invention has been made in view of such circumstances, and its purpose is to:
The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional technology by definitely identifying the model to be controlled while confirming the target model setting information so that the control suitable for the target model can be accurately executed.

[0004]

In order to achieve the above object, according to the structure of claim 1, the model information read from the storage means for storing a plurality of model information is displayed on the display means, When the manual type selection means is operated to the type selection state, one type information of the plurality of type information is set as the type setting information, and the control corresponding to the set type, that is, the type specified as the control target is executed. To be done.

Therefore, since the desired model information is set from the plurality of model information prepared in advance by checking the display, the error in the voltage setting of the DIP switch or the connection failure of the harness as in the prior art. For example, it is possible to reliably prevent erroneous model information from being set without knowing it, and it is possible to accurately execute control suitable for the target model.

According to the structure of claim 2, in the structure of claim 1, the manual switching means is operated to sequentially display one model information of the plurality of model information on the display means. When the manual model selection means is operated in the model selection state in this state, the displayed one model information is set as the model setting information.

Therefore, for example, in a case where all of the above-mentioned plurality of model information is displayed on the display means, and a target model is searched out and set from the display means, it is troublesome to search and a setting error occurs. Compared with the possibility that there is a risk, it is possible to set the model without error while displaying only the target model, and thus the operability and the reliability of the model setting operation are improved. Means are obtained.

Further, according to the structure of claim 3, in the structure of claim 1 or 2, the driving is performed while the model information is displayed on the display means and the manual model selection means is operated in the model selection state. When the power supply from the power source to each part of the machine is turned off, the model information displayed on the display means is set as model setting information.

Therefore, since the model information is set only when the engine key or the like is operated from the ON state to the OFF state in order to turn off the power supply from the drive power source to each part of the machine, for example, a manual type selection. If the means is configured with a push button switch, etc., and if the model is set only by operating the switch, it is possible to set a model that is not intended by pressing the switch without knowing It is possible to prevent the setting of the model information as much as possible, and therefore, it is possible to obtain the preferable means of the configuration according to claim 1 or 2, which further enhances the reliability of the model setting operation.
