- the operation unit 14 includes, for example, at least one operator 16 including push buttons, and in the present embodiment, six operation elements 16.
- the operation unit 14 having such a configuration outputs an operation signal indicating whether or not the operator 16 has been operated by the operation of the operator.
- the plurality of operators 16 of the display device 10 are described separately, the plurality of operators 16 may be described as the operators 16A, 16B, 16C, 16D, 16E, 16F, respectively.

- the control unit 22 includes a comparison unit 221.
- the processor of the control unit 22 functions as the comparison unit 221 by executing the computer program stored in the storage unit 24.
- the storage unit 24 is composed of a storage device that stores various data and computer programs. As various data, the storage unit 24 stores, for example, information such as setting information input in advance by the operator, the number of times the starter 520 is driven, which will be described later, and a reference value for the number of times the starter 520 is driven.
- the control unit 22 controls the entire construction machine 100, and executes automatic engine stop control for stopping the engine 510 when a preset set time elapses in a state where there is no operation by the operator (no operation state).
- This set time can be set, for example, between "5 minutes” and "1 hour”.
- the engine 510 will be described later.
- control unit 22 of the present embodiment executes automatic engine stop control based on the number of drives and the reference value, and when the number of drives reaches the reference value, the automatic stop time is extended or the automatic engine is stopped. Disable control.

- the starter 520 starts the engine 510. Specifically, the starter 520 starts the engine 510 when the operator performs a key operation on the construction machine 100.
- the comparison unit 221 compares the number of drives with the reference value. Specifically, for example, when the construction machine 100 is in a non-operated state, the comparison unit 221 compares the number of drives with the reference value. Note that, for example, the comparison unit 221 may compare the drive count with the reference value according to the measurement unit 26 measuring the drive count of the starter 520.
- the display unit 12 notifies the drive status of the starter 520 based on the number of drives and the reference value. In addition, the display unit 12 can also notify the result of comparison by the comparison unit 221. Specifically, when the number of drives exceeds the reference value, the display unit 12 executes a notification process for notifying that the number of drives exceeds the reference value. More specifically, the display unit 12 displays that the number of drives has exceeded the reference value in the notification process.
- the screen (notification screen) displayed on the display unit 12 in the notification processing will be described later.
- 2 (a) and 2 (b) are diagrams for explaining the automatic engine stop function.
- the time t1 indicates the time when the operation is not performed.
- the time t2 indicates the time when the automatic engine is stopped.
- the non-operated state indicates a state in which the construction machine 100 is not operated. Specifically, in the non-operation state, for example, the cutoff lever for prohibiting the operation of the construction machine 100 is lowered (operation valid state), and the operation lever for operating the construction machine 100 is operated. Indicates no state.
- the non-operation state includes a state in which the cutoff lever is raised (operation invalid state).
- the control unit 22 executes automatic engine stop control after the set time T1 has elapsed. Specifically, after the lapse of the set time T1, the control unit 22 stops the engine 510. Therefore, it is possible to suppress the consumption of fuel during non-working.
- the set time T1 and the automatic stop time Ta are equal.
- the time t1 indicates the time when the operation is not performed.
- the time t2 indicates the time when the initially set time T1 has elapsed from the no-operation state.
- the time t3 indicates the set time after the extension (set time T1 + extension time T2), that is, the time when the automatic engine is stopped.
- control unit 22 is configured to be able to set the automatic stop time Ta, and changes the set time until the automatic engine is stopped based on the result of comparison by the comparison unit 221.
- control unit 22 performs the first automatic engine stop control for changing the automatic stop time Ta based on the result of comparison by the comparison unit 221.
- the control unit 22 extends the automatic stop time Ta until the automatic engine stops (extension control of the automatic stop time Ta).
- the automatic stop time Ta is the time obtained by adding the set time T1 and the extension time T2.
- the control unit 22 sets, for example, the extension time T2 to the same value as the set time T1.
- the extended time T2 is a time that cannot be set by the operator.
- the extension time T2 may be set by the operator.
- control unit 22 may change the extension time T2 according to the number of drives. For example, the control unit 22 may increase the extension time T2 as the number of drives increases. Alternatively, the extension time T2 may be a fixed value.
- the control unit 22 may have a function of controlling the enablement or invalidation of the automatic engine stop function (invalidation control of the automatic engine stop function). Specifically, the control unit 22 may disable the automatic engine stop function based on the result of comparison by the comparison unit 221. More specifically, when the number of drives exceeds the reference value, the control unit 22 may perform the second automatic engine stop control for disabling the automatic engine stop function.
- extension control of the automatic stop time Ta and the invalidation control of the automatic engine stop function may be combined. For example, when the number of drives exceeds the reference value and the value of the number of drives thereafter is within a predetermined value, the control unit 22 executes the extension control of the automatic stop time Ta, and the value of the number of drives thereafter sets the predetermined value. If it exceeds, the control unit 22 may execute the invalidation control of the automatic engine stop function. In this way, by stepwise controlling the automatic engine stop, it is possible to solve the problem of starting the engine while ensuring the convenience of the operator.

Specifically, the control unit 22 executes the automatic engine stop time change process based on the comparison result with the first reference value, and invalidates the automatic engine stop function based on the comparison result with the second reference value. You may execute the conversion process.
