## Abstract

Provided is a remote operation system for surveying instruments, capable of making surveying instruments execute a necessary operation even when communication with a management server fails. The remote operation system for surveying instruments includes at least one master surveying instrument, a management server, and a remote terminal, configured to communicate with each other via a first communication network, and at least one slave surveying instrument configured to communicate with the master surveying instrument via a second communication network, wherein the management server transmits a first operation command to make the slave surveying instrument execute a first predetermined operation to the master surveying instrument, the master surveying instrument transmits the operation command to the slave surveying instrument, and the master surveying instrument transmits a second operation command to make the slave surveying instrument execute a second predetermined operation to the slave surveying instrument when communication with the management server fails.

## Claims

### Claim 1

A remote operation system for surveying instruments comprising:
at least one master surveying instrument; a management server; and a remote terminal, configured to communicate with each other via a first communication network; and
at least one slave surveying instrument configured to communicate with the master surveying instrument via a second communication network, wherein
the management server transmits a first operation command to make the slave surveying instrument execute a first predetermined operation to the master surveying instrument,
the master surveying instrument transmits the operation command to the slave surveying instrument, and
the master surveying instrument transmits a second operation command to make the slave surveying instrument execute a second predetermined operation to the slave surveying instrument when communication with the management server fails.

### Claim 2 (depends on 1)

The remote operation system for surveying instruments according to claim 1, wherein
the management server transmits, to the master surveying instrument, a transmission command to transmit data on the first predetermined operation to the management server,
the master surveying instrument transmits the data to the management server based on the transmission command, and
the master surveying instrument stands by for transmission of the data and stores data on the second predetermined operation when communication with the management server fails.

### Claim 3 (depends on 2)

The remote operation system for surveying instruments according to claim 2, wherein the master surveying instrument executes data transmission for which the master surveying instrument stands by when communication with the management server is restored.

### Claim 4 (depends on 3)

The remote operation system for surveying instruments according to claim 3, wherein the master surveying instrument stores the data in a compressed format according to date while communication with the management server is in failure, and transmits the data in the compressed format when communication with the management server is restored.

### Claim 5 (depends on 2)

The remote operation system for surveying instruments according to claim 2, wherein the master surveying instrument stores the data in a compressed format according to date while communication with the management server is in failure, and transmits the data in the compressed format when communication with the management server is restored.

### Claim 6 (depends on 1)

The remote operation system for surveying instruments according to claim 1, wherein the master surveying instrument executes data transmission for which the master surveying instrument stands by when communication with the management server is restored.

### Claim 7 (depends on 6)

The remote operation system for surveying instruments according to claim 6, wherein the master surveying instrument stores the data in a compressed format according to date while communication with the management server is in failure, and transmits the data in the compressed format when communication with the management server is restored.

### Claim 8 (depends on 1)

The remote operation system for surveying instruments according to claim 1, wherein the master surveying instrument stores the data in a compressed format according to date while communication with the management server is in failure, and transmits the data in the compressed format when communication with the management server is restored.
