(Remote terminal configuration)
FIG. 4 is a block diagram of a remote terminal according to an 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 shown in FIG. 4, the remote terminal RC has 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 input unit 34 is, for example, a keyboard or the like, and enables input of the following settings.

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. In the memory of the terminal control unit 32, the correspondence between the operation of the surveying instrument for creating the script and the symbol assigned to each operation is stored.

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

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

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

The server control unit 42 is a control unit including at least a CPU and a memory (ROM, RAM, etc.).

Send the symbol county.

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

The surveying instrument TS, the management server MS, and the remote terminal RC have agreed in advance on what kind of operation is to be performed with which symbol. As an example of the correspondence arrangement, 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, an operation number is assigned to the operation of the surveying instrument TS. FIG. 6 is an example of the script creation table 44.
Operation number 1: Performs distance measurement 5 times Operation number 2: Performs forward / reverse rotation Operation number 3: Performs automatic tilt correction Operation number 4: Rotates the vertical axis 6 in 5 second increments Operation number 5: In 5 second increments Operation number 6: Rotate the horizontal axis 11 Operation number 6: Update correction information Operation number 7: Check the horizontal rotation drive unit 5 Operation number 8: Check the vertical rotation drive unit 12 Operation number 9: ...
Operation number 10: ...

The correspondence (script creation table 44) stored in the database 43 is configured so that the data can be rewritten. When the correspondence relationship is rewritten in the database 43, the management server MS is configured to rewrite the recorded correspondence relationship 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 by 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 a script of operation 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 user calls the management company, the administrator provides support using the system of this embodiment.

First, in step S101, the administrator of the surveying instrument TS logs in to 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, so that the administrator selects the surveying instrument TS to be operated this time.

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

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, press "Finish" to define the selected actions as "scripts".

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 scripts are sequentially sent to the management server MS by the operation number, and the management server MS saves the operation number.

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

When the download is completed, the process proceeds to step S105, and the surveying instrument TS (script execution unit 27) illuminates the operation number against 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 (script execution unit 27) records the result of each operation in the storage unit 24. Alternatively, record the overall result when all operations are completed.

Specifically, when a script for confirming the above-mentioned axis distortion 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 drive unit 12 is driven three times, and the vertical angle of each is recorded. Subsequently, the horizontal rotation drive unit 5 is driven three times, and the horizontal angles of each are recorded. 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 measuring 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 (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 displaying the operation result. On the Web page 100, the presence / absence of an error and the error code if there is an error are displayed for each operation unit.

According to the remote control system of this embodiment, the surveying instrument TS can perform an operation arbitrarily set from a remote location. Therefore, when a problem occurs in the surveying instrument TS, various operation checks can be performed 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 combined operations can be easily performed.

In addition, by automatically sending the operation result after executing the script, the operation result of the remote operation can be confirmed immediately, so that the administrator can confirm the state of the surveying instrument in real time.

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

Here, a preferred modification of the present embodiment will be described. A remote operation is also preferable in which the 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 the image displayed 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 remote operation Web page in the modified example. The screen of the display unit 25 is reproduced on the Web page 100, and the operations and numerical values performed by the script are displayed in real time. By performing remote operation of this modified example, the administrator can check the state of the surveying instrument in more detail.

Although preferred embodiments and modifications of the present invention have been described above, they can be modified and combined based on the knowledge of those skilled in the art, and such embodiments are also included in the scope of the present invention.
