(Configuration of remote terminal)
FIG. 4 is a configuration block diagram of the remote terminal according to the embodiment. The remote terminal RC is a terminal such as a personal computer, a smartphone, or a tablet owned by a surveying instrument manufacturer or an agency. As illustrated in FIG. 4, the remote terminal RC includes at least a terminal communication unit 31, a terminal control unit 32, a terminal display unit 33, and a terminal input unit 34.

  The terminal communication unit 31 can transmit and receive information to and from the server communication unit 41 of the management server MS described later via the communication network N.

  The terminal input unit 34 is a keyboard, for example, and enables the following settings to be input.

  The terminal control unit 32 is a control unit including at least a CPU and a memory (ROM, RAM, etc.). The terminal control unit 32 sets a script for causing the surveying instrument TS to perform a series of operations. The memory of the terminal control unit 32 stores the correspondence between the operation of the surveying instrument for creating a script and the symbols given for each operation.

(Management server configuration)
FIG. 5 is a configuration block diagram of the management server according to the embodiment. As illustrated in FIG. 5, the management server MS includes at least a server communication unit 41, a server control unit 42, and a database 43.

  The server communication unit 41 can transmit / receive information to / from the communication unit 23 and the terminal communication unit 31 of the surveying instrument TS via the communication network N.

  In the database 43, information received from the surveying instrument TS and the remote terminal RC is stored in association with the management number of the surveying instrument TS. In addition, the correspondence relationship between the operation of the surveying instrument for creating the script and the symbol given for each operation is stored.

  The server control unit 42 is a control unit including at least a CPU and a memory (ROM, RAM, etc.). As will be described later, when the server control unit 42 receives a symbol group related to the operation of the surveying instrument TS from the remote terminal RC, the server control unit 42 stores it in the database 43 in association with the management number of the surveying instrument TS, and according to the request of the surveying instrument TS Send symbol county.

  Here, as a premise of the system of the present embodiment, the surveying instrument TS, the management server MS, and the remote terminal RC share the correspondence between the surveying instrument operation and the symbols given for each operation in advance. This will be described.

Arrangements have been made in advance between the surveying instrument TS, the management server MS, and the remote terminal RC as to what operation is performed with which symbol. As an example of the correspondence relationship, the surveying instrument TS, the management server MS, and the remote terminal RC each store a common script creation table 44. In the script creation table 44, for example, operation numbers are assigned to the operations of the surveying instrument TS. FIG. 6 is an example of the script creation table 44.
Operation number 1: Distance measurement is performed 5 times Operation number 2: Forward / reverse rotation operation number 3: Tilt automatic correction is performed operation number 4: Vertical axis 6 is rotated every 5 seconds Operation number 5: Every 5 seconds Operation number 6 for rotating the horizontal axis 11: Operation number 7 for updating correction information 7: Operation number 8 for checking the horizontal rotation drive unit 5: Operation number 9 for checking the vertical rotation drive unit 12:.
Operation number 10: ...

  The correspondence relationship (split creation table 44) stored in the database 43 is configured so that data can be rewritten. When the correspondence relationship is rewritten in the database 43, the recorded correspondence relationship is rewritten from the management server MS to the surveying instrument TS and the remote terminal RC. The same correspondence is always shared between the management server MS and the remote terminal RC.

  The remote terminal RC sets the operation to be performed by the surveying instrument TS using the operation number. The remote terminal RC transmits the operation number group to the management server MS via the terminal communication unit 31. The management server MS stores the operation number group received from the remote terminal RC. The management server MS transmits the operation number group to the surveying instrument TS. The surveying instrument TS creates and executes an operation script based on the operation number.

  Specifically, FIG. 7 is a work flowchart of the remote control system according to the embodiment. When a problem occurs in the surveying instrument TS and a telephone call is received from the user to the management company, the manager supports using the system of this embodiment.

  First, in step S101, the administrator of the surveying instrument TS logs into the dedicated web page 100 provided by the surveying instrument manufacturer from the remote terminal RC.

  Next, when the process proceeds to step S102, a list of a plurality of registered surveying instruments is displayed on the terminal display unit 33. Therefore, the administrator selects the surveying instrument TS to be operated this time.

  Next, when the process proceeds to step S103, a screen for setting a script to be performed by the surveying instrument TS is displayed. An interface for setting a script according to the script creation table 44 is mounted on the Web page 100.

  FIG. 8 is an example of a Web page when the script is set. The operation of the surveying instrument TS is displayed in a pull-down format together with the operation number, for example. The administrator selects an action from the list and presses the “Add” button. After selecting a series of actions and pressing “Done”, the action selected is defined as “Split”.

  As an example of creating a script for confirming the distortion of the vertical axis 6 and the horizontal axis 11, “3”, “5”, “5”, “5”, “4”, “4”, “4”, “3” “,” “1”, “6” are selected, “automatic tilt correction”, “rotate the horizontal axis 11 in 5 second increments”, “rotate the horizontal axis 11 in 5 second increments”, “ “Rotate the horizontal axis 11 in 5 second increments”, “Rotate the vertical axis 6 in 5 second increments”, “Rotate the vertical axis 6 in 5 second increments”, “Rotate the vertical axis 6 in 5 second increments” , “Perform automatic tilt correction”, “Perform distance measurement 5 times”, and “Update correction information” are set. The set script is sequentially transmitted to the management server MS with the operation number, and the management server MS stores the operation number.

  In step S104, the user who has been contacted by the administrator downloads the script (operation number group) from the management server MS using the surveying instrument TS.

  When the download is completed, the process proceeds to step S105, and the surveying instrument TS (split execution unit 27) compares the operation number with the script creation table 44, creates a script that performs the corresponding operation according to the operation number, and executes the script. . At that time, the surveying instrument TS (the script execution unit 27) records the result of each operation in the storage unit 24. Alternatively, the total result is recorded when all the operations are completed.

  Specifically, when the script for confirming the distortion of the axis is created, the script execution unit 27 executes the tilt automatic correction program and records the value of the tilt sensor 8 and the amount of deviation. Subsequently, the vertical rotation driving unit 12 is driven three times, and each vertical angle is recorded. Subsequently, the horizontal rotation driving unit 5 is driven three times to record each horizontal angle. Subsequently, the tilt automatic correction program is executed again, and the value of the tilt sensor 8 and the amount of deviation are recorded. Subsequently, the distance measuring unit 21 is driven to record the distance measurement value. Finally, the first tilt value is updated to the second tilt value, the distance measurement value is updated based on the updated tilt value, and the updated value is recorded. The script execution unit 27 causes the surveying instrument TS to automatically perform this series of operations.

  When all the scripts are executed, the process proceeds to step S106, and the surveying instrument TS (the script execution unit 27) transmits the operation result to the management server MS.

  Next, the process proceeds to step S107, and the management server MS transmits the operation result to the remote terminal RC. The remote terminal RC displays the operation result on the terminal display unit 33. FIG. 9 is an example of a Web page that displays the operation result. On the Web page 100, the presence / absence of an error and an error code if there is an error are displayed for each operation.

  According to the remote operation system of this embodiment, the surveying instrument TS can be made to perform an operation arbitrarily set from a remote location. For this reason, when a trouble occurs in the surveying instrument TS, various operations can be confirmed from a remote location.

  Further, since the remote operation is performed based on the symbol of the operation unit commonly recognized by the surveying instrument TS, the management server MS, and the remote terminal RC, complicated operations and combination operations can be easily performed.

  Moreover, since the operation result of the remote operation can be immediately confirmed by automatically transmitting the operation result after executing the script, the administrator can confirm the state of the surveying instrument in real time.

  In addition, as a result of checking the state of the surveying instrument, when additional confirmation is required, a new script can be set and executed immediately from the Web page 100, so that the problem solving process is accelerated.

  Here, a preferred modification of the present embodiment will be described. A remote operation is also preferable in which an image displayed on the display unit 25 of the surveying instrument TS is displayed on the Web page 100 in real time by communication between the surveying instrument TS, the management server MS, and the remote terminal RC. Specifically, when the operation by the script is started in step S105 of FIG. 7, the script execution unit 27 acquires an image shown on the display unit 25 and transmits it to the remote terminal RC via the management server MS.

  FIG. 10 is an example of a Web page for remote operation in a modified example. The screen of the display unit 25 is reproduced on the Web page 100, and operations and numerical values performed by the script are displayed in real time. If the remote operation of this modification is performed, the administrator can check the state of the surveying instrument in more detail.

    As mentioned above, although preferable embodiment and the modification of this invention were described, it is possible to modify and combine these based on the knowledge of those skilled in the art, and such a form is also included in the scope of the present invention.
