Abstract

A system includes: a device capable of surveying a measurement target or emitting laser light; an acceleration sensor capable of detecting an acceleration of the device; an output unit capable of outputting information; a storage unit configured to store: history information on the acceleration; and a correspondence table including a predetermined condition to be detected based on the acceleration and an operation detail in correspondence with each other; and a control unit configured to control output of the output unit based on the operation detail corresponding to the predetermined condition of the device associated in accordance with the history information, if the acceleration detected by the acceleration sensor is determined to correspond to the predetermined condition.

Claims (36)

1 . A system, comprising:

a device capable of surveying a measurement target or emitting laser light;

an acceleration sensor capable of detecting an acceleration of the device;

an output unit capable of outputting information;

a storage unit configured to store:

history information on the acceleration; and

a correspondence table including a predetermined condition to be detected based on the acceleration and an operation detail in correspondence with each other; and

a control unit configured to control output of the output unit based on the operation detail corresponding to the predetermined condition to be detected, of the device, associated in accordance with the history information, if the acceleration detected by the acceleration sensor is determined to correspond to the predetermined condition to be detected,

wherein

the correspondence table includes reference information that is a determination criterion set based on the history information in correspondence with the predetermined condition to be detected and the operation detail,

the reference information includes a threshold value and a pattern of a vibration or a displacement of the device,

the predetermined condition to be detected is external physical factors classifiable based on the acceleration and affecting an accuracy of the device, and

the control unit determines whether the acceleration detected by the acceleration sensor corresponds to predetermined condition to be detected, if the acceleration satisfies the determination criterion.

2 . The system of claim 1 , wherein

the control unit functions as a condition analyzer capable of determining whether the acceleration detected by the acceleration sensor corresponds to any one of conditions to be detected, by executing a trained program that has trained using the acceleration according to the history information and a condition of the device.

3 . The system of claim 1 , wherein

the acceleration is obtained by averaging detection values detected by the acceleration sensor at a predetermined number of detection times.

4 . The system of claim 1 , wherein

the operation detail includes a plurality of operation details corresponding to one or both of an abnormality handling operation and a condition transition.

5 . A device, comprising:

a surveying unit capable of surveying a measurement target or a rotary light projecting section capable of emitting laser light;

an acceleration sensor capable of detecting an acceleration;

an output unit capable of outputting information;

a storage unit configured to store:

history information on the acceleration; and

a correspondence table including a predetermined condition to be detected based on the acceleration and an operation detail in correspondence with each other; and

a control unit configured to control output of the output unit based on the operation detail corresponding to the predetermined condition to be detected associated in accordance with the history information, if the acceleration detected by the acceleration sensor is determined to correspond to the predetermined condition to be detected,

wherein

the correspondence table includes reference information that is a determination criterion set based on the history information in correspondence with the predetermined condition to be detected and the operation detail,

the reference information includes a threshold value and a pattern of a vibration or a displacement of the device,

the predetermined condition to be detected is external physical factors classifiable based on the acceleration and affecting an accuracy of the device, and

the control unit determines whether the acceleration detected by the acceleration sensor corresponds to predetermined condition to be detected, if the acceleration satisfies the determination criterion.

6 . A control method of a system, the system including:

a device capable of surveying a measurement target or emitting laser light; an acceleration sensor capable of detecting an acceleration of the device; an output unit capable of outputting information; and a storage unit configured to store history information on the acceleration and a correspondence table including a predetermined condition to be detected based on the acceleration and an operation detail in correspondence with each other, wherein the correspondence table includes reference information that is a determination criterion set based on the history information in correspondence with the predetermined condition to be detected and the operation detail, wherein the reference information includes a threshold value and a pattern of a vibration or a displacement of the device, and wherein the predetermined condition to be detected is external physical factors classifiable based on the acceleration and affecting an accuracy of the device, the control method characterized by comprising:

determining whether the acceleration detected by the acceleration sensor corresponds to the predetermined condition to be detected, of the device, if the acceleration satisfies the determination criterion; and

controlling output of the output unit based on the operation detail corresponding to the predetermined condition to be detected, if the acceleration detected is determined to correspond to the predetermined condition to be detected.
