  The mobile terminal 12 transmits preset test data to the construction machine 11. For example, when using the e-mail function of the mobile terminal 12 in advance, the test data is set with the identification information (for example, e-mail address) of the target construction machine 11 as the transmission destination, and the “text” of the e-mail. Or, the contents of the test data described above are written in “Subject”.

  Note that the setting of the transmission destination in the mobile terminal 12 is not limited to the mail address. For example, the test data is transmitted using address information such as an IP address or a MAC address set in advance for each construction machine 11. May be. Further, the mobile terminal 12 may transmit the test data using a short mail function in which a telephone number is set as a transmission destination instead of the electronic mail function. In this case, the address of the construction machine 11 is acquired from the telephone number by using a correspondence table of telephone numbers and addresses managed in advance in the portable mail server 14, and test data is transmitted to the predetermined construction machine 11. Is done.

  The mobile terminal 12 may be, for example, a mobile phone, a smartphone, a tablet PC (Personal Computer), a game machine, or the like, but is not limited thereto, and may be a portable information communication terminal. That's fine.

  The mobile mail transmission / reception antenna 13 transmits and receives data between the mobile terminal 12 and the mobile mail server 14. Specifically, the mobile mail transmitting / receiving antenna 13 receives the test data transmitted from the mobile terminal 12 and outputs the received test data to the mobile mail server 14. The test data in this case means mail format test data transmitted as e-mail, for example, but is not limited to this.

  The portable mail server 14 transmits and receives data between the portable mail transmitting / receiving antenna 13 and the satellite communication server 16. Note that a communication network 15 is interposed between the portable mail transmitting / receiving antenna 13 and the satellite communication server 16. Specifically, the mobile mail server 14 transmits the received test data to the satellite communication server 16 via the communication network 15 in order to transmit the received test data to the identification information (for example, address T) of the target construction machine 11. Note that the mobile mail server 14 may perform processing for converting the transmission content of the test data into a predetermined format. For example, for the test data transmitted using the short mail function, the mobile mail server 14 uses the telephone number and address correspondence table managed in advance, etc., from the telephone number to the address of the construction machine 11. And send test data to the acquired address.

  The satellite communication server 16 transmits and receives data between the mobile mail server 14 and the ground station 17. A communication network 15 is interposed between the mobile mail server 14 and the ground station 17. Specifically, the satellite communication server 16 outputs the test data acquired from the portable mail server 14 to the ground station 17 in order to transmit the test data to the destination construction machine 11 via the communication satellite 18. .

  The ground station 17 transmits and receives data between the satellite communication server 16 and the communication satellite 18. Specifically, the ground station 17 transmits test data obtained from the satellite communication server 16 to a predetermined communication satellite 18.

  The communication satellite 18 transmits and receives data between the construction machine 11 and the ground station 17. Specifically, the communication satellite 18 transmits the test data transmitted from the ground station 17 to the target construction machine 11 corresponding to the destination address.

  In the present embodiment, the mobile mail transmitting / receiving antenna 13, the mobile mail server 14, the communication network 15, the satellite communication server 16, the ground station 17, and the communication satellite 18 are provided between the mobile terminal 12 and the construction machine 11. It is a relay device for transmitting and receiving data.

  By having the system configuration as described above, the test data can be quickly and efficiently transmitted from the portable terminal 12 to the construction machine 11 without using the PC 20 or the operation management server 21. You can confirm the reception.

  Here, an example in which a service person or the like performs reception confirmation by the construction machine 11 using the system configuration of the management system 10 described above will be described. For example, when troubleshooting the reception function of the construction machine 11, first, a service person or the like visits a place where the target construction machine 11 is located. Thereafter, the service person transmits the address of the target construction machine 11 (in the example of FIG. 1, the address T) using, for example, the portable terminal 12 possessed by the service person in order to confirm the reception function of the construction machine 11. First, test data set in advance is transmitted.

  In the present embodiment, the test data transmitted from the mobile terminal 12 is received by the construction machine 11 without passing through the PC 20 or the operation management server 21 as described above, and it is determined whether the test data is test data. After being performed, the reception confirmation result is output to the display unit 32. In the present embodiment, the service person can confirm the contents displayed on the display unit 32, so that the reception can be confirmed quickly and efficiently. If the service person transmits test data from the mobile terminal 12 and the reception confirmation result is not displayed on the display unit 32 even after a predetermined time has elapsed, there is a problem with the communication equipment such as the antenna 30 and the communication path. It is possible to quickly grasp what has occurred.

  In the present embodiment, data is not transmitted and received directly from the portable terminal 12 to the construction machine 11. This is because, in order to enable direct data transmission / reception between the construction machine 11 and the portable terminal 12, a communication means must be provided separately from the antenna 30, leading to an increase in cost. Further, in the present embodiment, it is preferable that data can be transmitted / received correctly in transmission / reception of data with the operation management server 21 in normal business, and for this purpose, it is necessary to confirm reception by the antenna 30 that is normally used.

  In the present embodiment, for example, when a service person is in the construction machine 11, the user operating the PC 20-1 is instructed to send test data to the construction machine 11, and a confirmation of the reception result is displayed. It can also be performed based on the contents displayed on the part 32. In this case, identification information (for example, address C) of the PC 20-1 is displayed in the transmission source identification information displayed on the display unit 32. The PC 20-1 transmits preset test data. In this case, a process of changing the identification information (for example, address A) of the operation management server 21 that is a transmission destination of normal instruction data to the identification information (for example, address T) of the construction machine 11 is performed. The processing may be automatically performed using a program, an application, etc. Accordingly, even when test data is transmitted from the PC 20, the test data is quickly and efficiently transmitted to the construction machine 11 without going through the operation management server 21. Can be sent.

  Moreover, in this embodiment, you may transmit the test data from both the portable terminal 12 and PC20-1 mentioned above, and may perform the reception confirmation in the construction machine 11. In the present embodiment, as described above, by confirming reception of the test data from both, it is possible to confirm, for example, in which communication path a trouble has occurred.

  Here, as an example of normal data transmission / reception between the operation management server 21 and the construction machine 11, for example, when the construction machine 11 is stolen, the operation management server 21 cannot use the construction machine 11. Therefore, the construction machine 11 may be locked by transmitting a lock control signal. As another example of transmission / reception, for example, the operation management server 21 requests acquisition of various setting information and machine history information of the construction machine 11, and the construction machine 11 that has received the request is stored in a storage unit such as a memory. However, the present invention is not limited to this.
