  FIG. 4 is a schematic configuration diagram of a monitor device and a management center device according to an embodiment of the present invention.

  A monitor device (an example of a guidance output device) 22 of the construction machine S includes an engine operation detection unit 51, a key operation detection unit 52 as an example of a work detection unit, and an eco guidance determination unit 53 as an example of an occurrence detection unit. , A priority item determination unit 54, a guidance display control unit 55 as an example of an output control unit, a monitor screen 26, and a communication processing unit 57.

  The engine operation detection unit 51 detects whether or not the engine 40 is operating based on information from the engine controller 32 and notifies the priority item determination unit 54 of the operation time. The key operation detection unit 52 detects a key operation (key on or key off) by the operator based on information from the pump controller 33, for example. In addition, the key operation detection unit 52 monitors the voltage value on the downstream side of the key switch provided between the battery and various components (the monitor device 22, each pump controller 33, etc.) to perform the key operation. It can also be detected. When the key switch is turned on, the voltage value on the downstream side becomes the voltage value of the battery, so that the key operation can be detected. In addition, when various controllers such as the monitor device 22 are activated, power is supplied to the controller. Thus, a key operation can be detected based on the fact that the power is supplied. The key operation detection unit 52 notifies the eco-guidance determination unit 53 and the guidance display control unit 55 of information indicating the detected key operation. The monitor screen 26 has a liquid crystal display screen, for example, and displays various information.

  The eco-guidance determination unit 53 detects the occurrence of a plurality of fuel consumption deterioration operation operations (an example of energy wasting operation operations) based on information indicating the state of various sensors and switches output from the engine controller 32 and the pump controller 33. The generated fuel consumption deterioration driving operation is notified to the guidance display control unit 55, the number of occurrences of the fuel consumption deterioration driving operation is counted, and the number of occurrences of each fuel consumption deterioration driving operation is notified to the priority item determination unit 54. In the present embodiment, the eco-guidance determination unit 53 includes a daily number storage unit for storing the number of times the fuel consumption deterioration driving operation is performed every day (for example, every day from 0:00 to 24 hours), and from the previous key-on. It has a key-on count storage unit for storing the number of fuel consumption deterioration driving operations that occurred, detects the occurrence of multiple fuel consumption deterioration driving operations, counts each occurrence, and generates each fuel consumption deterioration driving operation The number of times is notified to the priority item determination unit 54.

  For example, as shown in FIG. 6, as the fuel consumption deterioration driving operation, a driving operation for performing idling for a long time (item name indicating operation: long-term idling) and a driving operation for continuing hydraulic relief (item name indicating operation) : Hydraulic relief) and driving operation that can be executed in energy saving mode (E mode) in another high energy mode (item name showing operation: E mode recommended) and driving with high throttle Driving operation (item name indicating operation: driving partial encouragement).

  Hereinafter, a hydraulic excavator will be described as an example of the construction machine S. In general, a hydraulic excavator is provided with a plurality of work modes indicating different types of basic work with different work loads. For example, there are work modes such as “P mode” and “E mode”. When performing work, one of the work modes can be selected according to the content of the work to be performed by the worker himself. The hydraulic excavator performs different controls according to the selected work mode. The outline of each work mode is as follows.

The “P mode” is a work mode (emphasis on work amount) for performing excavation work with a large load, and its operation characteristics are expressed using an engine torque curve and a pump output curve. It becomes like a). That is, the engine rotational speed operates so as to be substantially constant at N _A, the output of the pump (horsepower) also operates as a constant PS _A.

The above-mentioned “E mode” is an operation mode (considering fuel efficiency) for performing excavation work with a load smaller than that of the P mode, and its operation characteristics are expressed using an engine torque curve and a pump output curve. As shown in FIG. What is indicated by a broken line is a curve in the P mode. That is, the engine rotational speed operates so as to be substantially constant at N _B, operates as the output of the pump is also constant in PS _B.

  Refer to FIG. 6 again. Long-term idling is a driving operation that satisfies the condition that there is no driving operation by the operator (operations on the travel levers 15, 16, the control levers 19, 20, etc.) and the state continues for a predetermined time. There is a driving operation by the operator (operation of the working machine levers 19 and 20), and the pump pressure (pressure of the hydraulic oil output from the pump) is other than the warm-up operation, and the hydraulic relief pressure (hydraulic relief is performed). Is the driving operation that satisfies the condition that the state of being equal to or higher than the pressure) is continued for a predetermined time, and the E mode recommendation is the driving operation that satisfies the condition that the generated horsepower is within the E mode range, The driving partial recommendation is driving that satisfies the condition that there is a driving operation and the condition that the throttle designation is equal to or greater than a predetermined amount continues for a predetermined time. It is a work. As to whether the engine is warming up or not, for example, whether a predetermined time (for example, 5 minutes) has elapsed since the start of the engine 40, or whether the engine water temperature is equal to or lower than a predetermined temperature. Alternatively, the determination can be made based on at least one of whether the oil temperature of the hydraulic oil is equal to or lower than a predetermined temperature.

  The eco-guidance determination unit 53 detects the occurrence of each fuel consumption deterioration driving operation by determining whether or not the above-described fuel consumption deterioration driving operation condition is satisfied. In the present embodiment, since the eco-guidance determination unit 53 is in a state other than the warm-up operation as a condition of one hydraulic pressure relief operation, the fuel-consumption determination operation 53 is not performed during the warm-up operation. The guidance display control unit 55 is not notified of the occurrence of the fuel consumption deterioration driving operation, so that the guidance for the hydraulic relief is not displayed. For this reason, the guidance for stopping the warm-up operation is not displayed during the warm-up operation necessary for the construction machine S.

  The priority item determination unit 54 determines the fuel consumption deterioration driving operation to be preferentially output the energy saving guidance operation based on the number of times of the fuel consumption deterioration driving operation notified from the eco guidance determination unit 53, and performs the guidance. The display control unit 55 is notified. For example, the priority item determination unit 54 determines that the energy-saving guidance should be preferentially output for the fuel consumption deterioration operation with a large number of occurrences. Here, as the number of times used for comparison, either the number of times per day or the number of times since key-on is used based on the setting. For example, on the basis of the number of times since key-on, for example, when operation is performed such that key-on is performed every time the operator is changed, appropriate guidance can be determined for the operating operator. .

  Note that the priority item determination unit 54 preferentially saves energy based on the number of times of the fuel consumption deterioration driving operation notified from the eco guidance determination unit 53 and the average information notified from the communication processing unit 57. May be determined to determine the fuel consumption deterioration driving operation to be output. Here, the average information is information related to the average number of times of the respective fuel consumption deterioration operation operations in the same kind of construction machine S. For example, the same kind of construction machine (the same kind of construction machine S is a hydraulic excavator ( It may be the one having the same bucket capacity), or the reciprocal of the average value of the respective times of the fuel consumption deteriorating driving operations generated in the same type of construction machine such as a wheel loader as a loading machine). When the average information is the reciprocal of the average value of the number of occurrences in the same kind of construction machine, the priority item determination unit 54 determines the number of times each of the fuel consumption deterioration driving operations notified from the eco guidance determination unit 53, and Multiplying the reciprocal of the average value corresponding to the fuel efficiency deteriorated driving action, and the result of multiplication is determined to output the energy saving guidance preferentially for the largest fuel economy deteriorated driving action. In this case, instead of simply deciding the guidance to output with priority given by comparing the number of driving operations with deteriorated fuel efficiency, the guidance to output with priority given to the operating status of other construction machines. Therefore, it can be determined that priority should be given to the guidance for the operation operation with poor fuel consumption (more frequent occurrences) than with other construction machines.

  In the present embodiment, when the comparison value is the same, the priority item determination unit 54 determines the fuel consumption deterioration driving operation to which the guidance should be output according to a predetermined priority order. Specifically, for example, when the comparison values are the same, it is determined that the message is output with priority in the order of idling for a long time, E mode recommendation, travel partial recommendation, and hydraulic relief.

  Moreover, the priority item determination part 54 notifies the guidance display control part 55 that it is excellent driving | running | working, when the frequency | count of occurrence of each fuel consumption deterioration operation driving | operation is 0 times. In the present embodiment, the priority item determination unit 54 is a good driving when the operation time is a predetermined time (for example, one hour) or more and the number of occurrences of each fuel consumption deterioration operation driving is zero. This is notified to the guidance display control unit 55. In this way, by setting the operating time as a predetermined time or more, it is possible to prevent notification that the driving is excellent when the driving is performed in a very short time such that the driving operation with a deteriorated fuel efficiency is hardly generated. ing.

  Further, the priority item determination unit 54 notifies the communication processing unit 57 of driving information including the number of occurrences of the respective fuel consumption deterioration driving operations.

  The guidance display control part 55 memorize | stores the guidance corresponding to each fuel consumption deterioration driving operation. As shown in FIG. 6, the guidance display control unit 55, as guidance for one fuel consumption deterioration driving operation, for example, eco guidance that is a guidance for immediate output when a fuel consumption deterioration driving operation is detected; A one-point guidance that is a guidance for outputting at a predetermined timing (in the present embodiment, at the time of key-on and key-off) after the detection of the fuel consumption deterioration operation is stored. For example, the guidance display control unit 55 stores “Let's refrain from idling for a long time” as eco-guidance for long-term idling, and “One-time guidance can reduce fuel consumption by frequent idling stop” Is remembered.

  Further, when the guidance display control unit 55 receives a notification of the occurrence of the fuel consumption deterioration driving operation from the eco guidance determination unit 53, as shown in FIG. 5A, the screen 70 showing the engine water temperature, the oil temperature, and the fuel amount. Is also displayed on the monitor screen 26 together with the guidance 71 corresponding to the fuel consumption deterioration operation. In the present embodiment, the guidance display control unit 55 displays an abnormality display of the construction machine (for example, the engine) on the monitor screen 26 even when the eco-guidance determination unit 53 receives a notification of the occurrence of the fuel consumption deterioration driving operation. When the water temperature is overheated), the guidance display corresponding to the fuel consumption deterioration driving operation is made lower than the priority of the abnormality display priority on the monitor screen 26. Do not display. Note that the priority of the abnormality display may be set in advance higher than the priority of display of any guidance corresponding to the fuel consumption deterioration operation. In the example shown in FIG. 5A, the engine water temperature, the oil temperature, and the fuel amount are displayed on the monitor screen 26. However, at least the engine water temperature and the fuel amount may be displayed.

  When the guidance display control unit 55 receives information indicating that a key-on or key-off operation has been performed from the key operation detection unit 52, the guidance display control unit 55 performs the fuel consumption deterioration driving operation notified by the priority item determination unit 54 as shown in FIG. 5B. A screen 80 including the corresponding guidance 81 (in this embodiment, one-point guidance) is displayed on the monitor screen 26. In this embodiment, the guidance display control unit 55 stores the guidance displayed at the time of the previous key-off, and displays the screen 80 including the stored guidance 81 on the monitor screen 26 at the time of the next key-on. Let Note that the guidance display control unit 55 may display guidance only at the time of key-on or key-off.

  When the guidance display control unit 55 receives a notification that the driving is excellent from the priority item determination unit 54, the guidance display control unit 55 displays on the monitor screen 26 that the driving is good. Thus, since it is displayed that it is excellent driving | operation, the motivation with respect to a driving | operation of an operator can be improved. When the guidance display control unit 55 receives a change message from the communication processing unit 57, the guidance display control unit 55 displays the change message on the monitor screen 26 instead of the guidance. In addition, when the guidance display control unit 55 receives data such as a picture, color, and sound along with the change message, the guidance display control unit 55 performs image display and sound output based on the received data.

  Further, the guidance display control unit 55 displays the eco guidance recording screen 90 shown in FIG. 5C on the monitor screen 26 when receiving an instruction to display the eco guidance recording screen from the operator. On the eco-guidance record screen 90, as shown in FIG. 5C, a number display area 92 for displaying the number of occurrences of each fuel consumption deterioration driving operation and a guidance (in this embodiment, one-point guidance) are displayed. A point guidance display area 93. Note that FIG. 5C shows an example of a screen when the guidance is set according to the number of times per day, but for example, when the guidance is set according to the number of times from key-on. The number of times since key-on is displayed, and guidance is determined and displayed based on the number of times since key-on.

  The communication processing unit 57 receives the operation information from the priority item determination unit 54 and transmits the operation information to the management center device 60 including identification information of the construction machine S or an operator (for example, a driver). Further, the communication processing unit 57 receives the average information from the management center device 60 and passes it to the priority item determination unit 54. The communication processing unit 57 receives the change message from the management center device 60 and passes it to the guidance display control unit 55. In addition, the communication processing unit 57 receives data such as a picture, color, and sound from the management center device 60 and passes the data to the guidance display control unit 55.

  A management center device 60 installed in a management center that manages a plurality of construction machines S includes a communication processing unit 61, a totaling processing unit 62, a totaling database 63, and a disclosure processing unit 64.

  The communication processing unit 61 communicates with a plurality of construction machines S. The communication processing unit 61 receives operation information from the plurality of construction machines S and passes the received operation information to the aggregation processing unit 62. The communication processing unit 61 receives average information from the totalization processing unit 62 and transmits the average information to each construction machine S. The communication processing unit 61 receives the change message from the totalization processing unit 62 and transmits the change message to the construction machine S. In addition, when the communication processing unit 61 receives data such as a picture, a color, and sound along with the change message, the communication processing unit 61 transmits them to the construction machine S.

  The aggregation processing unit 62 stores the operation information received from the communication processing unit 61 in the aggregation database 63.

The aggregation processing unit 62 transmits a change message to be displayed on the construction machine S via the communication processing unit 61 when a predetermined condition is satisfied based on the operation information. For example, the totalization processing unit 62 performs driving with respect to the construction machine S when the number of the fuel consumption deterioration driving operation indicated by the driving information is small with respect to the construction machine S of the same type, that is, when it is superior. Send an excellent message. In addition to the change message displayed on the construction machine S, the totalization processing unit 62 can transmit data such as a picture, color, and voice via the communication processing unit 61.

  The total database 63 stores operation information received from a plurality of construction machines. The publication processing unit 64 generates various WEB pages 65 based on the information in the summary database 63, and publishes them so that they can be viewed. The public processing unit 64 generates, for example, a WEB page 65 that includes the average number of times of the fuel consumption-deteriorating driving operations of the same kind of construction machines S, the ranking of the number of times of the fuel consumption-deteriorating driving operations of the construction machines S, and the like.

It is displayed (step S2). In this way, immediately after key-on, the guidance corresponding to the fuel consumption deterioration driving operation that occurred during the previous driving is displayed, so the operator can work with that guidance in mind during the current driving, as a result This will lead to improved fuel economy.

  Next, the eco-guidance determination unit 53 determines whether or not a plurality of fuel consumption deterioration driving operation conditions are satisfied (step S3), and if the conditions are not satisfied, the process proceeds to step S6.

  On the other hand, when the condition is satisfied (step S3: YES), the generated fuel consumption deterioration driving operation is notified to the guidance display control unit 55, and the number of occurrences of the corresponding fuel consumption deterioration driving operation is counted (step S4). The priority item determination unit 54 is notified of the number of occurrences of the fuel consumption deterioration operation. In this embodiment, the number of times per day and the number of times since key-on are counted.

  When the guidance display control unit 55 receives a notification of the occurrence of the fuel consumption deterioration driving operation from the eco guidance determination unit 53, for example, as shown in FIG. 5A, construction such as engine water temperature, hydraulic oil temperature, and fuel amount is constructed. Guidance 71 (eco guidance) corresponding to the fuel consumption deterioration operation is also displayed on the monitor screen 26 together with the screen 70 showing the state of the machine (step S5). Thereby, it is possible to prompt the operator to appropriately suppress the fuel consumption deterioration driving operation currently occurring.

  Next, the key operation detection unit 52 determines whether or not key-off has occurred (step S6), and when key-off has not occurred (step S6: NO), the process proceeds to step S3. On the other hand, when the key-off occurs, the key operation detection unit 52 notifies the eco-guidance determination unit 53 and the guidance display control unit 55 of the information that the key-off has occurred, and the eco-guidance determination unit 53 The priority item determination unit 54 is notified of the number of occurrences of the deteriorated driving operation. Based on the notified number of occurrences, the priority item determination unit 54 determines a fuel consumption deterioration driving operation (priority item) that gives priority to output the guidance (step S7), and notifies the guidance display control unit 55 of it. As shown in FIG. 5B, the guidance display control unit 55 displays a screen 80 including a guidance 81 (in the present embodiment, one-point guidance) corresponding to the fuel consumption deterioration driving operation notified by the priority item determination unit 54. Are displayed (step S8), and the process is terminated. In this way, since the guidance corresponding to the fuel consumption deterioration driving operation that occurred in the driving is displayed at the time of key-off, the operator can look back on the fuel consumption deterioration driving operation that occurred in the current driving, and to the subsequent driving Can be useful.

  In the present embodiment, when a key-off operation is performed (step S6: YES), the parts that operate until step S8 ends (for example, the guidance display control unit 55, the monitor screen 26, etc.). ) Power supply is maintained. As a configuration for maintaining the power supply (power maintaining unit) in this way, for example, a control unit that controls the relay so as not to cut off the power supply from the battery may be provided until step S8 ends. Or you may make it have another battery for supplying electric power required after the electric power supply from a main battery stops by key-off until the process of step S8 is complete | finished.

  In order to maintain the power supply, for example, as shown in FIG. 11, the power supply line can be constituted by a power supply 110, a key switch 111, a CPU 112, an OR circuit 113, and an internal power supply switch 114. The power supply 110 is connected to the CPU 112 and the OR circuit 113 via the key switch 111. The key switch 111 and the CPU 112 are connected to the internal power switch 114 via the OR circuit 113. The CPU 112 is supplied with power from the power source 110 via the internal power switch 114.

  The OR circuit 113 and the internal power switch 114 are realized by discrete components such as transistors. Further, it is assumed that the CPU 112, the OR circuit 113, and the internal power switch 114 exist in the monitor device 22.

  When the key switch 111 is turned on, power is supplied from the power supply 110 to the OR circuit 113. The ON signal is supplied to the CPU 112. The internal power switch 114 is turned on by the OR circuit 113, and power is supplied to the CPU 112 via the internal power switch 114. When receiving the ON signal, the CPU 112 outputs a signal for turning on the internal power switch 114 to the OR circuit 113.

  On the other hand, when the key switch 113 is turned off, the off signal is supplied to the OR circuit 113. However, the internal power switch 114 cannot be turned off only by the off signal from the key switch 113 due to the logical function of the OR circuit 113. In the example illustrated in FIG. 11, the OR circuit 113 includes an off signal from the key switch 111 and an off signal from the CPU 112 (an off signal transmitted to the OR circuit 113 after a predetermined time has elapsed after the CPU 112 has received the off signal). The internal power switch 114 can be turned off.

  That is, even when the key switch 111 is turned off, the internal power switch 114 is in the on state, so that the power supply to the CPU 112 via the internal power switch 114 is maintained. However, the CPU 112 recognizes that the ON signal (power supply) from the power supply 110 is not supplied. The CPU 112 can adjust the time for transmitting the off signal to the OR circuit 113 by a necessary time from the time when it is recognized that the on signal (power supply) is not supplied. Therefore, with the configuration shown in FIG. 11, even when the key switch 111 is turned off, it is possible to maintain the power supply for a predetermined time and to operate.

  FIG. 8 is a flowchart of information communication processing with the management center apparatus according to an embodiment of the present invention. The information communication process in FIG. 8 is executed, for example, after 0:00 of each day is exceeded.

  The communication processing unit 57 has received the operation information from the priority item determination unit 54 in advance, and transmits the operation information including the identification information of its own construction machine S to the management center device 60 (step S11).

  On the other hand, in the management center device 60, the communication processing unit 61 receives the operation information from the construction machine S and passes the received operation information to the aggregation processing unit 62. The totalization processing unit 62 stores the operation information received from the communication processing unit 61 in the totalization database 63, and calculates information related to the average number of times of each fuel consumption deterioration driving operation in the same kind of construction machine S based on the information in the totalization database 63. To the communication processing unit 61. Next, the communication processing unit 61 transmits the average information received from the aggregation processing unit 62 to the construction machine S.

  Thereafter, the communication processing unit 57 of the construction machine S receives the average information from the management center device 60 and stores it in a predetermined storage unit so that it can be used by the priority item determination unit 54 (step S13). Thus, thereafter, the priority item determination unit 54 can use the average information, and can select the guidance to be preferentially output in consideration of the number of occurrences in other construction machines S.

  FIG. 9 is a flowchart of guidance record display processing according to an embodiment of the present invention.

  The priority item determination unit 54 determines whether or not there is a guidance display request from the operator. If there is no guidance display request (step S21: NO), the priority item determination unit 54 waits until there is a guidance display request.

  On the other hand, when there is a guidance display request (step S21: YES), the priority item determination unit 54 preferentially saves energy based on the number of times each of the fuel consumption deterioration driving operations notified from the eco guidance determination unit 53. The operation for deteriorating the fuel consumption that should output the guidance is determined (step S22), and the guidance display control unit 55 is notified. The guidance display control unit 55 displays a number-of-times display area 92 in which the number of times of the fuel consumption deterioration driving operation shown in FIG. 5C is displayed based on the notified fuel consumption deterioration driving operation, and guidance (one point in this embodiment).

  For example, in the above-described embodiment, identification information for identifying the operator is used, and the eco-guidance determination unit 53 associates the identification information with the number of fuel consumption deterioration driving operations that occurred during the operation of the operator. The priority item determination unit 54 may determine the fuel consumption deterioration driving operation that outputs the guidance with priority based on the number of times associated with the identification information of the key-on operator. In this way, it is possible to appropriately output guidance for each operator. Here, as a method for the construction machine S to accept the operator identification information, for example, the operator may directly input the identification information by the push button 27, or a storage medium (for example, an operator identification information is stored). , An IC card, an ID key (a key having a memory function)) may be prepared, and the construction machine S may be provided with a function unit (identification information acquisition unit) for reading from the storage medium.

  Further, the guidance display control unit (guidance storage means for each operator) 55 stores the operator identification information and the guidance of the fuel consumption deterioration driving operation determined to be preferentially output in association with each other, at the time of key-on, The identification information of the operator who is keyed on may be received and guidance corresponding to the identification information may be displayed. In this way, it is possible to output appropriate guidance for each operator at the time of key-on.

  In the above embodiment, the communication is performed once every day after 0:00. However, the present invention is not limited to this, and may be performed, for example, every key-on, or every key-off. Alternatively, it may be performed every predetermined time (for example, every hour).

  Further, in the above embodiment, the guidance of the fuel consumption deterioration driving operation is displayed based on the key-on and the key-off, but the present invention is not limited to this, and instead of the key-on and the key-off, the engine on, the engine off, The battery voltage may be supplied to or stopped from the monitor device 22 and the monitor screen display may be turned on or off. In short, the time may be substantially the same as the start and end of work.

  In the above embodiment, the communication processing unit 57 may exist outside the monitor device 22. In this case, information to be transmitted / received is exchanged with the monitor device 22 via the in-vehicle network (CAN (Controller Area Network)).

  In the above embodiment, the fuel wasting operation is shown as an example of the energy wasting operation. However, for example, in a construction machine equipped with a motor that uses electric power, the power wasting operation is performed as an energy wasting operation. It may be a driving operation.

  In the above embodiment, the guidance to be preferentially output is determined based on the number of energy waste operation operations. However, the guidance to be preferentially output is determined based on the frequency of energy waste operation operations. You may make it do.
