Control the flow control valve. That is, in the hydraulic control, the flow control valve that controls the hydraulic actuator (swing cylinder, boom cylinder C3, arm cylinder C4, bucket cylinder) is controlled.

  When the control devices 19L and 19R are being operated in the automatic idle control, the control device 30 outputs a control signal corresponding to the amount of operation of the accelerator to the engine to increase or decrease the engine rotation speed. When the 19R is not operated, the engine speed is fixed to the idling state by outputting a control signal indicating the idling speed to the engine.

  In the boom height control, the control device 30 stops the raising operation of the boom 15 regardless of the operation of the control devices 19L and 19R when the height of the boom 15 reaches the preset upper limit value of the boom height.

The above-described control is an example and is not limited, and the control device 30 executes necessary control according to the mode of the work machine 1.
The control device 30 includes a first storage unit 33 and a timer unit 34. The timer unit 34 includes electrical / electronic components provided in the control device 30, a program stored in the control device 30, and the like. The timer 34 calculates the operating time from when the engine speed detected by the engine speed sensor is input to the control device 30 (start of driving) to when the input of the engine speed to the control device 30 ends (driving end). To do. In other words, the timer unit 34 obtains the time (elapsed time) during which the engine is driven by a timer or the like. For example, when the engine is continuously driven between 9 o'clock and 12 o'clock, the operation time (elapsed time) is 3 hours. The timer 34 obtains an accumulated operation time (hour meter) by accumulating the calculated operation time every time the engine is driven (from the start of engine drive to the end of engine drive). In this embodiment, the cumulative value of the operating time from the start of driving of the engine to the end of driving is used as the cumulative operating time. Not. The 1st memory | storage part 33 is comprised from a non-volatile memory etc., and memorize | stores the cumulative operation time which the time measuring part 34 timed.

  As shown in FIG. 1, the work machine 1 has a communication device 40.

  The communication device 40 includes a collection unit 42 and a storage unit 43. The collection unit 42 includes electrical / electronic components provided in the communication device 40, a program stored in the communication device 40, and the like. The collection unit 42 collects machine information related to the work machine. Specifically, the communication device 40, the control device 30 provided in the work machine 1, and devices such as sensors are connected by the communication line L1 and the like, and the collection unit 42 receives various signals ( Data) as machine information. Specifically, the collection unit 42 collects signals from various sensors, accumulated operation time, and the like as machine information when the control device 30 performs control such as auto idle control, boom height control, and arm height control. . In the above-described embodiment, the signal and cumulative operation information when the control device 30 performs control are used as machine information, but the machine information collected by the collection unit 42 is not limited. The collection unit 42 may collect information on a failure or warning of a device mounted on the work machine 1 as machine information, or may collect setting values of the machine of the work machine 1 as machine information. Any information about 1 can be used.

The storage unit 43 is configured by a non-volatile memory or the like, and temporarily stores the machine information collected by the collection unit 42. The machine information temporarily stored in the storage unit 43, that is, the machine information collected by the collection unit 42 is transmitted to the external device 50 by the communication device 40 (first communication unit 41).
The external device 50 is a portable terminal such as a tablet, a smartphone, or a PDA that can be carried. The portable terminal 50 can be connected to the communication device 40 provided in the work machine 1, and can transmit and receive various data (information) to and from the communication device 40. The portable terminal 50 has a second communication unit 51. The second communication unit 51 is composed of components that perform short-distance and long-distance communication. For example, Bluetooth (registered trademark) Low Energy in the specification of the Bluetooth (registered trademark) of the communication standard IEEE 802.15.1 series is used. Wireless communication with the communication device 40 is performed. Note that the second communication unit may perform wireless communication through a mobile phone communication network, a data communication network, a mobile phone communication network, or the like.

  The portable terminal 50 includes a storage unit 52, a display unit 53, and a processing unit 54. The storage unit 52 is a non-volatile memory and stores machine information received from the communication device 40, various application software (applications), an operation system (OS), and the like. The display unit 53 can display various types of information, and is composed of a liquid crystal panel or the like. The processing unit 54 includes an electric / electronic component provided in the mobile terminal 50, a program (application, OS) stored in the mobile terminal 50, and the like. The processing unit 54 executes various processes of the mobile terminal 50.

Next, connection between the portable terminal 50 and the communication device 40 will be described.
As illustrated in FIG. 2, the first communication unit 41 of the communication device 40 outputs a beacon B. When the portable terminal 50 (second communication unit 51) is located outside the beacon B in the communication area E1 (area where the beacon B can be transmitted), the processing unit 54 executes an acquisition process for acquiring machine information. do not do. The acquisition process is a process in which application software (referred to as an acquisition application) for acquiring machine information of the work machine 1 and storing it in the portable terminal 50 is read from the storage unit 52 and activated. If 50 is outside the communication area E1, the acquisition application is not activated. The acquisition application is an application for performing processing for acquiring machine information, and a program for performing acquisition processing by being installed in the mobile terminal 50, because the mobile terminal 50 and the communication device 40 are connected. Necessary information (service UUID, PIN code, etc.), activation information G1, which will be described later, and the like are stored in the portable terminal 50.

  When the portable terminal 50 is in the communication area E1, when the second communication unit 51 of the portable terminal 50 receives the beacon B, the processing unit 54 starts the acquisition process for acquiring machine information, and acquires the information. Launch the app. The processing unit 54 executes the connection process after the acquisition application is started (after the acquisition process is started). In the connection process, at least the processing unit 54 instructs the second communication unit 51 to connect to the communication device 40. The second communication unit 51 receives a command from the processing unit 54 and transmits a connection request to the communication device 40, and communication is performed between the communication device 40 and the second communication unit 51. When communication is established between the communication device 40 and the second communication unit 51, the processing unit 54 causes the machine information transmitted from the communication device 40 to be acquired by an operation (processing) such as an acquisition application. When the acquisition of the machine information is completed, the processing unit 54 ends the connection process when the second communication unit 51 receives a signal indicating that the machine information scheduled to be transmitted is transmitted from the communication device 40, for example. The communication between the second communication unit 51 and the communication device 40 is disconnected. The communication device 40 outputs the beacon B again after the communication with the second communication unit 51 is disconnected.

FIG. 3 shows a flowchart of the connection between the portable terminal 50 and the communication device 40. The connection between the portable terminal 50 and the communication device 40 will be described in detail with reference to FIG.
As illustrated in FIG. 3, the communication device 40 has a data capacity of machine information (untransmitted information) that has not been transmitted to the mobile terminal 50 among all machine information (all machine information) stored in the storage unit 43. Is determined to be greater than or equal to a predetermined value (S1). When the data capacity of the untransmitted information is greater than or equal to a predetermined value (S1, Yes), the first communication unit 41 of the communication device 40 transmits a beacon B to request the mobile terminal 50 to acquire machine information. (S2: transmission step). When the second communication unit 51 of the portable terminal 50 receives the beacon B (S3), the processing unit 54 determines whether or not to execute the acquisition process based on information included in the beacon B (S4).

  FIG. 4 illustrates a beacon B packet (advertisement packet) Q1. As shown in FIG. 4, the packet Q1 includes activation information F1 and connection information F2. The activation information F1 is information for triggering the start of the acquisition process. When the activation information F1 included in the beacon B (packet Q1) transmitted by the communication device 40 and the same activation information G1 are stored in the storage unit 52 of the portable terminal 50, the processing unit 54 determines to execute the acquisition process. (S4, Yes). On the other hand, when the activation information F1 included in the beacon B (packet Q1) transmitted by the communication device 40 and the same activation information G1 are not stored in the storage unit 52 of the portable terminal 50, the processing unit 54 performs the acquisition process. It is determined not to execute (S4, No).

  FIG. 5 shows the relationship between the activation information F1 of the beacon B transmitted by the communication device 40 and the activation information G1 stored in the storage unit 52 of the portable terminal 50. As shown in FIG. 5, when the activation information F1 transmitted by the communication device 40 is “5411” and the activation information G1 stored in the storage unit 52 of the portable terminal 50 is “5411”, both activation information Since they match, the processing unit 54 determines to execute the acquisition process. On the other hand, when the activation information F1 transmitted by the communication device 40 is “5400” and the activation information G1 stored in the storage unit 52 of the mobile terminal 50 does not store “5400”, both activation information is Since they do not match, the processing unit 54 determines not to execute the acquisition process. In the above-described embodiment, the acquisition process is executed when the same activation information G1 as the activation information F1 of the beacon B is stored in the mobile terminal 50. Instead, the activation information of the beacon B is executed. When the activation information G1 associated with F1 is stored in the mobile terminal 50, the processing unit 54 may execute an acquisition process.

  When determining that the processing unit 54 executes the acquisition process (S4, Yes), the processing unit 54 starts the acquisition process and starts the acquisition application (S5: acquisition execution step). When the activation of the acquired application is completed, the processing unit 54 executes a connection process (S6: connection execution step). For example, after executing the connection process, the processing unit 54 performs a connection process to the communication device 40 using the received connection information F2. The connection information F2 is information for connecting to the communication device 40. For example, the connection information F2 is a service UUID, PIN code, or the like, and the second communication unit 51 transmits the service UUID or PIN code to the communication device 40. As a result, the connection between the portable terminal 50 and the communication device 40 is established. Note that the processing related to the connection between the portable terminal 50 and the communication device 40 is the same as the conventional one, and performs authentication of a service UUID or PIN code.

  After connecting to the mobile terminal 50 (second communication unit 51), the communication device 40 transmits the machine information (untransmitted machine information) in the storage unit 43 to the mobile terminal 50 (S7). The communication device 40 notifies the mobile terminal 50 that the transmission of the machine information is completed, and when the processing unit 54 receives that the transmission of the machine information is completed, the processing unit 54 completes the acquisition of the machine information. (S8) A disconnection request is made to the communication device 40 (S9). In response to the disconnection request from the mobile terminal 50, the communication device 40 disconnects communication with the mobile terminal 50 and transmits a disconnection completion notification to the mobile terminal 50 (S10). When the portable terminal 50 receives the disconnection completion, the processing unit 54 ends the connection process (S11: connection completion step). After the communication with the mobile terminal 50 is disconnected, the communication device 40 returns to the process of outputting the beacon B, and outputs the beacon B continuously and repeatedly every time the connection completion step ends. In addition, the portable terminal 50 stores the machine information received from the communication device 40 in the storage unit 52.

The machine information stored in the storage unit 52 of the portable terminal 50 can be displayed on the display unit 53 or transmitted to an external device different from the portable terminal 50, such as a server or a personal computer.
According to the above, it is a data communication system of a working machine including the communication device 40 and the portable terminal 50 that can execute the connection process and the acquisition process, and the communication device 40 performs the acquisition process on the portable terminal 50. A beacon B including start information F1 to be started and connection information F2 to execute the connection process is transmitted. In addition, the portable terminal 50 starts the acquisition process when the activation information F1 is acquired, and acquires the machine information from the communication device 40 by executing the connection process after the acquisition process is started.

  For this reason, only by receiving the beacon B transmitted from the communication device 40, the portable terminal 50 can execute the acquisition process and the connection process. Machine information can be acquired automatically. For example, the worker who owns the work implement or the operator who operates the work implement only possesses the portable terminal 50, and the machine information of the work implement 1 is automatically obtained even if the worker does not operate. Can be acquired.

  The processing unit 54 ends the connection process when the acquisition of machine information is completed. For this reason, since the connection process ends when the mobile terminal 50 acquires the machine information, the connection between the mobile terminal 50 and the communication device 40 can be prevented, and the communication device 40 is connected to another mobile terminal 50. On the other hand, a new beacon B can be transmitted. For example, if the first mobile terminal owned by the worker A, the second mobile terminal owned by the worker B, and the first mobile terminal and the second mobile terminal exist in the same communication area E1, the first mobile terminal However, since the connection process ends immediately after obtaining the machine information from the communication device 40, the second portable terminal can obtain the machine information from the communication device 40.

Further, the communication device 40 continuously and repeatedly transmits a beacon including the activation information F1 and the connection information F2. For this reason, after the communication with the predetermined portable terminal 50 is disconnected, the connection with another portable terminal 50 can be performed immediately, and the machine information can be transmitted to another portable terminal 50.
Now, the communication device 40 can transmit a plurality of beacons. For example, the communication device 40 can transmit a first beacon (first beacon) B1 and a second beacon (second beacon) B2 including second activation information at different timings. The first beacon B1 and the second beacon are different beacons. The first beacon B1 includes first activation information, and the second beacon B2 includes second activation information.

FIG. 6 shows a state in which the communication device 40 transmits the first beacon B1 and the second beacon B2 to the predetermined portable terminal 50. For example, assuming that the first activation information is “5411” and the second activation information is “5412”, the connection between the communication device 40 and the portable terminal 50 will be described.
As shown in FIG. 6, when the mobile terminal 50 receives the first beacon B1 including the first activation information at the position P1 that is the boundary of the communication area E1, the mobile terminal 50 receives the first beacon B1 as shown in FIG. Since the same activation information as the first activation information is stored, the processing unit 54 of the portable terminal 50 executes an acquisition process and a connection process. Thereafter, when the portable terminal 50 receives the same first beacon B1 as the beacon received at the position P1 at the position P2 in the communication area E1, that is, the same activation information as the trigger for starting the acquisition process at the position P1. When the first beacon B1 including the activation information is acquired at the position P2 different from the position P1, the processing unit 54 does not execute the acquisition process.

  In addition, when the mobile terminal 50 receives a second beacon B2 that is different from the first beacon B1 at the position P3 in the communication area E1, the processing unit 54 receives the second beacon B2 as a trigger. The acquisition application is activated by the same process as that performed in B1, that is, the start of the acquisition process. And the portable terminal 50 acquires machine information from the communication apparatus 40 by performing a connection process after the start of an acquisition process.

  That is, when the portable terminal 50 executes the acquisition process in response to the reception of the first beacon B1 in the communication area E1, the acquisition process is executed even if the same first beacon B1 is subsequently received. Without performing the acquisition process, the second beacon B2 different from the first beacon B1 is received. In addition, when the portable terminal 50 performs the acquisition process triggered by the reception of the second beacon B2, the acquisition process is not performed even if the same second beacon B2 is subsequently received. The acquisition process is executed when a beacon different from the beacon B1 and the second beacon B2 is received.

According to the above, when the mobile terminal 50 receives a beacon having the same activation information a plurality of times in a situation located in the communication area E1, the mobile terminal 50 does not execute the acquisition process using the beacon for the second time and thereafter.
The mobile terminal 50 receives a beacon (referred to as an old beacon) in the communication area E1, performs the acquisition process triggered by the reception of the old beacon, and then the mobile terminal 50 goes out of the communication area E1. When the old beacon cannot be received, and the portable terminal 50 reenters the communication area E1 and receives the same beacon as the old beacon, at least once using the same beacon as the old beacon. May perform acquisition processing. That is, when the mobile terminal 50 goes out of the communication area E1 and temporarily receives the first beacon B1 or the second beacon B2, the acquisition process is performed by the first beacon B1 or the second beacon B2. You may go.

  FIG. 7 shows a flowchart when the communication device 40 transmits the first beacon B1 and the second beacon B2 to the predetermined portable terminal 50. In the description of FIG. 7, the description will proceed on the assumption that the predetermined portable terminal 50 has not entered the communication area E <b> 1 and has not left the communication area E <b> 1. 7, S1 to S3 and S5 to S11 are the same as FIG. 6 except that the communication device 40 transmits the first beacon B1.

  When the communication device 40 has a data capacity of untransmitted information equal to or greater than a predetermined value and requests connection to the mobile terminal 50 (S1, Yes), the first communication unit 41 of the communication device 40 uses the first beacon B1. Is transmitted (S2: first transmission step). When the second communication unit 51 of the portable terminal 50 receives the first beacon B1 (S3), the processing unit 54 determines whether or not to execute the acquisition process based on information included in the first beacon B1. (S4).

  When the activation information included in the first beacon B1 is stored in the storage unit 52 of the mobile terminal 50 and the acquisition process has not been performed by the first beacon B1, the processing unit 54 performs the acquisition process. It is determined to be executed (S4, Yes). On the other hand, when the activation information included in the first beacon B1 is not stored in the storage unit 52 of the mobile terminal 50, or even when the activation information included in the first beacon B1 is stored in the storage unit 52, If the acquisition process has already been performed by one beacon B1, the processing unit 54 determines not to execute the acquisition process (S4, No). After the process of S4, the communication device 40 and the mobile terminal 50 execute S5 to S10 as described above.

  After connecting to the portable terminal 50 by the first beacon B1 (after S11), the communication device 40 determines whether or not the data capacity of the untransmitted information is greater than or equal to a predetermined value (S20). When the data capacity of the untransmitted information is greater than or equal to a predetermined value and the mobile terminal 50 is requested to connect (S20, Yes: second transmission step), the first communication unit 41 transmits the second beacon B2 ( S21). In other words, in the second transmission step, when the machine information stored in the storage unit 43 is updated after the transmission of the first beacon B1 and the mobile terminal 50 is requested to acquire the updated machine information.

The communication device 40 transmits the machine information stored in the storage unit 43 (S26). After acquiring the machine information, the processing unit 54 makes a disconnection request to the communication device 40 (S27). The communication device 40 disconnects the communication with the mobile terminal 50 and transmits a disconnection completion notification to the mobile terminal 50 (S28). When the portable terminal 50 receives the disconnection completion, the processing unit 54 ends the connection process (S29: connection completion step).

  According to the above, the communication device 40 (first communication unit 41) can transmit a plurality of beacons, and the processing unit 54 has the same information as the beacon that triggered the execution of the processing among the plurality of beacons. When the first beacon B1 having the first beacon B1 is received, the process is not executed. When the second beacon B2 different from the first beacon B1 is received, the same process as the process performed by the first beacon B1 is performed. That is, the processing unit 54 does not execute the acquisition process when acquiring the first beacon B1 including the same activation information as the activation information that triggered the start of the process among the plurality of beacons, and does not execute the acquisition process. The acquisition process is executed when the second beacon B2 having different activation information is acquired.

  According to this, under the situation where the portable terminal 50 is located in the communication area E1, the portable terminal 50 can be caused to execute an arbitrary process triggered by the first beacon B1 and the second beacon B2. For example, when the process triggered by the first beacon B1 and the second beacon B2 is an acquisition process, the portable terminal 50 automatically receives machine information from the work machine 1 at different timings while being in the communication area E1. Can be obtained.

  In addition, the portable terminal 50 includes a storage unit 52 that stores first activation information associated with the first beacon B1 and second activation information associated with the second beacon B2, and the processing unit 54 stores The same processing is executed when the first beacon B1 corresponding to the first activation information stored in the unit 52 is acquired and when the second beacon B2 corresponding to the second activation information stored in the storage unit 52 is acquired. To do.

  According to this, in the situation where the portable terminal 50 is located in the communication area E1, the portable terminal 50 executes the same processing on the portable terminal 50 using the first beacon B1 and the second beacon B2 as a trigger. Can be made. For example, when application software is installed in the mobile terminal 50, the application software can be activated at different timings depending on the first beacon B1 and the second beacon B2.

  The 1st communication part 41 transmits 2nd beacon B2, when connecting with the portable terminal 50 by the 1st beacon B1 and requesting the connection with respect to the said portable terminal 50. Under the situation where the portable terminal 50 is located in the communication area E1, the work machine 1 (first communication unit 41) is connected to the portable terminal 50 at different timings by the first beacon B1 and the second beacon B2. Can do.

  In addition, the communication device 40 includes a collection unit 42 and a storage unit 43, and the first communication unit 41 requests the mobile terminal 50 to acquire machine information stored in the storage unit 43.
