The storage unit 43 is composed of 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 around. The mobile 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 processing unit 54 executes various processes of the mobile terminal 50.

Next, the connection between the mobile terminal 50 and the communication device 40 will be described.
As shown in FIG. 2, the first communication unit 41 of the communication device 40 outputs the beacon B. When the mobile terminal 50 (second communication unit 51) positions the beacon B outside the communication area E1 (area in which 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 of reading the application software (referred to as an acquisition application) for acquiring the machine information of the work machine 1 and storing it in the mobile terminal 50 from the storage unit 52 and starting the processing unit 54. When 50 is outside the communication area E1, the acquisition application is not started. The acquisition application is an application for performing processing for acquiring machine information, and is a program for performing acquisition processing by installing it on the mobile terminal 50, because the mobile terminal 50 and the communication device 40 are connected. Information (service UUID, PIN code, etc.) necessary for the mobile terminal 50, activation information G1 to be described later, and the like are stored in the mobile terminal 50.

When the mobile terminal 50 is in the communication area E1, when the second communication unit 51 of the mobile terminal 50 receives the beacon B, the processing unit 54 executes the start of the acquisition process for acquiring the machine information and acquires the beacon B. Launch the app. The processing unit 54 executes the connection process after the acquisition application is started (after the acquisition process is started). The connection process means that at least the processing unit 54 instructs the second communication unit 51 to connect to the communication device 40. The second communication unit 51 transmits a connection request to the communication device 40 in response to a command from the processing unit 54, 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 communication device 40 to acquire the machine information transmitted from the communication device 40 by the operation (processing) of the acquisition application or the like. When the acquisition of the machine information is completed, the processing unit 54 ends the connection process when, for example, the second communication unit 51 receives a signal indicating that the machine information to be transmitted is transmitted from the communication device 40. 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 disconnecting the communication with the second communication unit 51.

FIG. 3 shows a flowchart of connection between the mobile terminal 50 and the communication device 40. The connection between the mobile terminal 50 and the communication device 40 will be described in detail with reference to FIG.
As shown 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 equal to or larger than a predetermined value (S1, Yes), the first communication unit 41 of the communication device 40 transmits the beacon B in order to request the mobile terminal 50 to acquire the machine information. (S2: Transmission step). When the second communication unit 51 of the mobile terminal 50 receives the beacon B (S3), the processing unit 54 determines whether or not to execute the acquisition process based on the information contained in the beacon B (S4).

FIG. 4 shows a packet (advertisement packet) Q1 of the beacon B. 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 mobile terminal 50, the processing unit 54 determines that the acquisition process is executed. (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 mobile 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 mobile 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 mobile terminal 50 is "5411", the activation information of both is Since they match, the processing unit 54 determines that the acquisition process is to be executed. 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", the activation information of both is Since they do not match, the processing unit 54 determines that the acquisition process is not executed. 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 the acquisition process.

When the processing unit 54 determines that the processing unit 54 executes the acquisition process (S4, Yes), the processing unit 54 executes the start of the acquisition process and starts the acquisition application (S5: acquisition execution step). When the start of the acquisition application is completed, the processing unit 54 executes the 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, a service UUID, a PIN code, etc., 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 mobile terminal 50 and the communication device 40 is established. The process related to the connection between the mobile terminal 50 and the communication device 40 is the same as in the conventional case, and the service UUID or PIN code is authenticated.

After connecting to the mobile terminal 50 (second communication unit 51), the communication device 40 transmits the machine information (untransmitted machine information) of 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). The communication device 40 disconnects the communication with the mobile terminal 50 in response to the disconnection request from the mobile terminal 50, and transmits a notification of the completion of disconnection to the mobile terminal 50 (S10). When the mobile terminal 50 receives the disconnection completion, the processing unit 54 ends the connection process (S11: connection completion step). After disconnecting the communication with the mobile terminal 50, the communication device 40 returns to the process of outputting the beacon B, and continuously and repeatedly outputs the beacon B each time the connection completion step is completed. Further, the mobile 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 mobile terminal 50 can be displayed on the display unit 53 or transmitted to an external device different from the mobile terminal 50, for example, a server or a personal computer.
According to the above, it is a data communication system of a work machine including a communication device 40 and a mobile terminal 50 capable of executing connection processing and acquisition processing, and the communication device 40 performs acquisition processing on the mobile terminal 50. The beacon B including the activation information F1 to be started and the connection information F2 to execute the connection process is transmitted. Further, the mobile terminal 50 starts the acquisition process when the activation information F1 is acquired, and executes the connection process after the start of the acquisition process to acquire the machine information from the communication device 40.

Therefore, the mobile terminal 50 can execute the acquisition process and the connection process only by receiving the beacon B transmitted from the communication device 40, and the mobile terminal 50 is triggered by the reception of the beacon B. Machine information can be acquired automatically. For example, if the worker who owns the work machine or the worker who operates the work machine only has the mobile terminal 50, the machine information of the work machine 1 is automatically obtained even if the worker does not operate it. Can be obtained.

In addition, the processing unit 54 ends the connection process when the acquisition of machine information is completed. Therefore, since the connection process is completed when the mobile terminal 50 acquires the machine information, it is possible to prevent the mobile terminal 50 and the communication device 40 from being continuously connected, and the communication device 40 can be connected to another mobile terminal 50. On the other hand, the beacon B can be newly transmitted. For example, when 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 The connection process is completed immediately after the machine information is acquired from the communication device 40, so that the second mobile terminal can acquire the machine information from the communication device 40.

Further, the communication device 40 continuously and repeatedly transmits a beacon including activation information F1 and connection information F2. Therefore, after disconnecting the communication with the predetermined mobile terminal 50, it is possible to immediately connect to another mobile terminal 50 and transmit the machine information to the other mobile terminal 50.
By the way, the communication device 40 can transmit a plurality of beacons. For example, the communication device 40 can transmit the first beacon (first beacon) B1 and the second beacon (second beacon) B2 including the second activation information at different timings. The information contained in the first beacon B1 and the second beacon is different, the first beacon B1 includes the first activation information, and the second beacon B2 includes the 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 a predetermined mobile 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 mobile 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 which 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 mobile terminal 50 executes the acquisition process and the connection process. After that, when the mobile 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 as the activation information that triggered the start of the acquisition process at the position P1. When the first beacon B1 including the activation information is acquired at a position P2 different from the position P1, the processing unit 54 does not execute the acquisition process.

Further, when the mobile terminal 50 receives the second beacon B2 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 an opportunity to receive the first beacon B2. The acquisition application is started by the same process as the process performed in B1, that is, by starting the acquisition process. Then, the mobile terminal 50 acquires machine information from the communication device 40 by performing a connection process after the start of the acquisition process.

That is, when the mobile terminal 50 executes the acquisition process in the communication area E1 triggered by the reception of the first beacon B1, the acquisition process is executed even when the same first beacon B1 is subsequently received. Instead, when the second beacon B2 different from the first beacon B1 is received, the acquisition process is executed. When the mobile terminal 50 executes the acquisition process triggered by the reception of the second beacon B2, the mobile terminal 50 does not execute the acquisition process even if the same second beacon B2 is subsequently received, and the first When a beacon different from the beacon B1 and the second beacon B2 is received, the acquisition process is executed.

According to the above, when the mobile terminal 50 receives the beacon having the same activation information a plurality of times under the condition of being located in the communication area E1, the mobile terminal 50 does not execute the acquisition process by the beacon from the second time onward.
The mobile terminal 50 receives a beacon (referred to as an old beacon) in the communication area E1 and executes an 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 mobile terminal 50 reenters the communication area E1 and receives the same beacon as the old beacon, the same beacon as the old beacon is used as an opportunity at least once. May execute the acquisition process. That is, when the mobile terminal 50 goes out of the communication area E1 and once becomes unable to receive 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 a predetermined mobile terminal 50. In the description of FIG. 7, the description will proceed on the premise that the predetermined mobile terminal 50 has entered the communication area E1 and has not left the communication area E1. In FIG. 7, S1 to S3 and S5 to S11 are the same as those in 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 larger than a predetermined value and requests the mobile terminal 50 to connect (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 mobile terminal 50 receives the first beacon B1 (S3), the processing unit 54 determines whether or not to execute the acquisition process based on the information contained 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 never been performed by the first beacon B1, the processing unit 54 performs the acquisition process. Judge to execute (S4, Yes). On the other hand, even when the activation information included in the first beacon B1 is not stored in the storage unit 52 of the mobile terminal 50, or the activation information included in the first beacon B1 is stored in the storage unit 52, the first When the acquisition process has already been performed by the beacon B1, the processing unit 54 determines that the acquisition process is not executed (S4, No). After the processing of S4, the communication device 40 and the mobile terminal 50 execute S5 to S10 as described above.

After connecting to the mobile 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 equal to or greater than a predetermined value (S20). When the data capacity of the untransmitted information is equal to or larger than 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 (S20, Yes: second transmission step). 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 second beacon B1 is transmitted.

When the second communication unit 51 of the mobile terminal 50 receives the second beacon B2 (S22), the processing unit 54 determines whether or not to execute the acquisition process based on the information contained in the second beacon B2. (S23). When the activation information included in the second beacon B2 is stored in the storage unit 52 of the mobile terminal 50 and the acquisition process has never been performed by the second beacon B2, the processing unit 54 performs the acquisition process. Judge to execute (S23, Yes). On the other hand, even when the activation information included in the second beacon B2 is not stored in the storage unit 52 of the mobile terminal 50, or the activation information included in the second beacon B2 is stored in the storage unit 52, the second beacon 2 If the acquisition process has already been performed by the beacon B2, the processing unit 54 determines that the acquisition process is not executed (S23, No).

When the processing unit 54 determines that the acquisition process is to be executed (S23, Yes), the processing unit 54 starts the acquisition process and starts the acquisition application (S24). That is, the processing unit 54 executes the same processing as the first beacon B1 even when the second beacon B2 is received. In other words, even if a plurality of application softwares are stored in the mobile terminal 50, the processing unit 54 uses the same application software in the acquisition process regardless of whether the first beacon B1 is received or the second beacon B2 is received. to start.

When the start of the acquisition application is completed, the processing unit 54 executes the connection process (S25: connection execution step). 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 executes disconnection of communication with the mobile terminal 50, and transmits a notification of the completion of disconnection to the mobile terminal 50 (S28). When the mobile 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 above is received, the process is not executed, and 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, when the processing unit 54 acquires the first beacon B1 including the same activation information as the activation information that triggered the start of processing among the plurality of beacons, the processing unit 54 does not execute the acquisition process and does not execute the acquisition process. When the second beacon B2 whose activation information is different from the above is acquired, the acquisition process is executed.

According to this, in the situation where the mobile terminal 50 is located in the communication area E1, the mobile terminal 50 can be made to execute an arbitrary process by using the first beacon B1 and the second beacon B2 as an opportunity. For example, when the process triggered by the first beacon B1 and the second beacon B2 is the acquisition process, the mobile terminal 50 automatically performs machine information from the work machine 1 at different timings while staying in the communication area E1. Can be obtained.

Further, the mobile terminal 50 has a storage unit 52 that stores the first activation information associated with the first beacon B1 and the second activation information associated with the second beacon B2, and the processing unit 54 stores the storage unit 52. The same process 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 a situation where the mobile terminal 50 is located in the communication area E1, the mobile terminal 50 executes the same process on the mobile terminal 50, triggered by the first beacon B1 and the second beacon B2, respectively. Can be made to. For example, when the application software is installed on the mobile terminal 50, the application software can be started at different timings by the first beacon B1 and the second beacon B2.

After connecting to the mobile terminal 50 by the first beacon B1, the first communication unit 41 transmits the second beacon B2 when requesting the connection to the mobile terminal 50. In a situation where the mobile terminal 50 is located in the communication area E1, the work machine 1 (first communication unit 41) is connected to the mobile terminal 50 at different timings by the first beacon B1 and the second beacon B2. Can be done.

Further, when the communication device 40 has a collection unit 42 and a storage unit 43, and the first communication unit 41 requests the mobile terminal 50 to acquire the machine information stored in the storage unit 43. The first beacon B1 is transmitted to. According to this, the machine information of the work machine 1 can be transmitted to a predetermined mobile terminal 50 by the first beacon B1. When the second beacon B2 is acquired, the second communication unit 51 connects to the communication device 50 that transmitted the second beacon B2.

Further, the first communication unit 41 updates the machine information stored in the storage unit after the transmission of the first beacon B1, and requests the mobile terminal 50 to acquire the updated machine information. The beacon B2 is transmitted. According to this, after the machine information of the work machine 1 is transmitted to the predetermined mobile terminal 50 by the first beacon B1, when the machine information of the work machine 1 is updated, the updated machine information is transmitted to the mobile terminal 50. can do.
