  At present, construction machines are required to have higher functions of electronic control devices installed in order to realize advanced construction such as information construction for the purpose of improving work accuracy and efficiency. On the other hand, the demand for low-priced machines for emerging countries is high, and therefore, the cost reduction of electronic control devices is required. As described above, since the market demand is divided into two, the electronic control device mounted on the construction machine needs to cope with these two conflicting demands.

  In addition, the construction machine has a long maintenance period, and the cycle of improving the performance of the electronic control device is short compared to the generation change of the machine. For this reason, performance improvement and function expansion of an electronic control apparatus equipped with an electronic control device of a future standard are frequently required regardless of the generation change of the machine. For this reason, in an electronic control device for a construction machine, a lot of design man-hours are required for performance improvement and function expansion.

  Furthermore, construction machinery is produced in a variety of products compared to automobiles and the like, and there are many variations of electronic control devices. For this reason, in the electronic control device for construction machines, more man-hours are required for performance improvement and function expansion.

  Therefore, in electronic control equipment for construction machinery, performance is improved by ensuring high compatibility and affinity between controllers that realize standard functions and controllers that realize advanced functions equipped with future standard electronic devices. It is desirable to reduce the man-hours required for function expansion.

  As a controller that considers the expansion of the functions of an electronic control device, a technique is known in which hardware having an extended function is added to hardware having a standard function. As an example of such a technique, there is a technique as described in Patent Document 1 described above.

  However, in the technique described in Patent Literature 1, no consideration is given to the number of man-hours generated when the function of the controller is expanded. Further, no consideration is given to expansion of future standard electronic control devices that exceed the performance of current standard electronic control devices. Furthermore, there is a problem that no consideration is given to a system configuration method when an electronic control device is applied to a construction machine or the like.

  With the technology described in Patent Document 1, it is difficult to cope with high functionality and low cost version required for an electronic control device mounted on a construction machine, frequent generation change, and multi-product production. Therefore, there is a grudge that cannot perform smooth performance improvement and function expansion.

  The present invention provides an electronic control device that is particularly promising for a construction machine, which can easily improve performance and expand functions in an electronic control device mounted inside a vehicle body such as a construction machine.

  In order to solve the above problems, for example, the configuration described in the claims is adopted.

For example, the present invention is connected to basic hardware connected to the backbone network and an extended network having a communication standard different from the backbone network.

The first connector port 501 is an opening for allowing a cable to be connected to the first communication connector 411 and the first input / output connector 412 from the outside of the housing 500. The second connector port 502 is an opening for allowing a cable to be connected to the second communication connector 413 and the second input / output connector 414 from the outside of the housing 500. The heat dissipating part 503 is an opening for cooling a portion where the heat generated by the basic hardware 11 and the expansion hardware 12 is large.

  In this embodiment, since the expansion hardware 12 is mounted on the basic hardware 11 and the controller 10 is expanded, the housing 500 also has the first connector port 501 on the lower side in FIG. The connector port 502 is provided on the upper side of FIG.

Further, in the present embodiment, the housing 500 is configured in a size that matches the basic hardware 11.

  With these configurations, physical expansion is less likely to occur when function expansion is performed by providing the expansion hardware 12 and the like, and thus easier expansion is possible.

  Next, an outline of the system design method will be described with reference to FIG. FIG. 6 is a flowchart illustrating a system design method in the electronic control apparatus according to the present embodiment.

  When extending the controller 10 of the present embodiment, the designer first checks the function expansion conditions that can be realized by the basic hardware 11 (step S600), and whether or not all the function expansion conditions by the basic hardware 11 are satisfied. Is determined (step S601).

  The function expansion conditions of the basic hardware 11 in steps S600 and S601 are, for example, whether the function expansion standard can be supported, whether there is no input / output addition / change, whether the processing performance is sufficient, or whether the process change / addition man-hour is Is it acceptable?

  When all the function expansion conditions of the basic hardware 11 are satisfied (step S601 → Yes), the function expansion of the basic hardware 11 is performed (step S602).

  On the other hand, if even one of the function expansion conditions of the basic hardware 11 is not satisfied (step S601 → No), then the function expansion conditions that can be realized by the expansion hardware 12 are confirmed (step S603), and the expansion hardware 12 It is determined whether or not the function expansion condition is satisfied by all functions (step S604).

  The function expansion condition of the expansion hardware 12 in steps S603 and S604 is, for example, whether the size of the expansion hardware 12 when the function is expanded fits in the capacity and area of the housing 500, or the input / output device controlled at the time of function expansion is Whether it is mounted in the vicinity of the input / output device connected to the basic hardware 11, is the temperature, vibration resistance, and noise resistance in the casing 500 at the time of function expansion acceptable?

  When all of the function expansion conditions of the expansion hardware 12 are satisfied (step S604 → Yes), the function expansion is performed using only the expansion hardware 12 (step S605).

  On the other hand, if there is a condition that does not satisfy the function expansion conditions of the expansion hardware 12 (step S604 → No), it is determined whether or not the function expansion condition of the expansion hardware 12 is satisfied by some of the functions to be expanded. (Step S606).

  When a part of the function to be expanded satisfies the function expansion condition of the expansion hardware 12 (step S606 → Yes), some of the function expansion is performed by the expansion hardware 12, and the other function expansion is performed by the expansion controller 30. (Step S607).

  On the other hand, if a part of the function to be expanded does not satisfy the function expansion condition of the expansion hardware 12 (step S606 → No), the function expansion is performed only by the expansion controller 30.
