Master Surveying Instrument Local Command Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for surveying instruments fail to execute necessary operations when communication between the surveying instruments and the management server is disrupted, leading to operational discontinuity.
Innovation Solution
A remote operation system comprising a master surveying instrument, a management server, and slave surveying instruments, where the master instrument acts as a intermediary to transmit and store operation commands and data, allowing continuous operation even when communication with the management server is lost, and resumes data transmission upon restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surveying instruments communicate directly with the management server via the Internet, then remote operation and management is enabled, but operational continuity is lost when communication fails
Solution Approach 1:
The master surveying instrument serves as an intermediary between slave surveying instruments and the management server. When communication with the server fails, the master instrument receives and stores operation commands locally, enabling slave instruments to continue executing tasks without direct server connectivity, thus maintaining operational continuity while preserving remote management capability
Solution Approach 2:
The system performs preliminary actions by having the master surveying instrument store operation commands and data locally before communication failure occurs. This preliminary data storage ensures that when the Internet connection fails, the instruments can continue operating with pre-stored commands rather than halting immediately
2Productivity
If the system waits for server communication to resume before storing data, then data transmission efficiency is improved, but data loss occurs during communication failures
Solution Approach 1:
The master surveying instrument performs preliminary data storage locally when communication with the management server fails. Instead of waiting for server connectivity to resume before storing any data, the system proactively stores operation commands and measurement data in the master instrument's storage unit, preventing data loss while maintaining efficient data transmission when connectivity is available
Solution Approach 2:
The system provides beforehand cushioning by implementing local storage capability in the master surveying instrument. This cushioning mechanism buffers against communication failures by temporarily holding operation commands and data locally, ensuring continuous operation and preventing data loss during Internet disconnections

AI summary
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.
