Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for designing and laying out VHF communication base stations rely on previous experience, making it impossible to accurately determine communication coverage distance and call effect during the engineering consultation and design stage due to varying geographical locations and environments.
Innovation Solution
A method and system that utilize mobile stations to send or receive audio data at different distances to a temporary VHF communication base station, allowing for the accurate determination of coverage distance and transmission effect, which involves a server sending test parameter information and start instructions to mobile and base stations, and receiving audio and location data to assess coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If VHF communication base station layout relies on previous construction experience, then design process is simple and quick, but communication coverage distance and call effect cannot be accurately determined
Solution Approach 1:
The patent introduces a server as an intermediary component that coordinates between mobile stations and base stations. The server sends test instructions, collects audio data and location information from multiple stations, and processes the data to determine coverage distance and call effect. This intermediary architecture enables accurate measurement without requiring complex direct coordination between all testing components.
Solution Approach 2:
The patent uses mobile stations to temporarily simulate or represent the communication characteristics of actual base stations during testing. By having mobile stations send and receive audio data at different locations, the system creates a virtual model of base station coverage that can be measured and analyzed without requiring permanent installation of multiple base stations for testing purposes.
2Reliability
If VHF communication base station layout relies on previous construction experience, then design stage is fast and efficient, but call effect after construction cannot be predicted
Solution Approach 1:
The patent performs coverage testing during the engineering consultation and design stage, before actual base station construction is completed. By conducting tests with temporary base stations and mobile stations in advance, the system determines coverage distance and call effect predictions early in the process. This preliminary action allows optimization of the permanent base station layout before construction, avoiding costly changes later while maintaining reliable communication performance.
Solution Approach 2:
The testing system uses existing mobile stations and temporary base stations that are already available in the field, rather than requiring specialized testing equipment. The mobile stations utilize their own audio communication capabilities and location services to generate test data, reducing the need for additional dedicated testing resources and minimizing testing time.
3Length of stationary object
If antenna installation height is increased to extend transmission distance, then communication distance increases, but installation cost and complexity increase
Solution Approach 1:
The patent uses the testing system to measure actual coverage distance and call effect at different locations and conditions. By analyzing the test results, engineers can determine the optimal antenna installation height that achieves the required transmission distance without unnecessarily increasing height. The parameter optimization is based on empirical data from tests rather than theoretical calculations or experience-based estimates.
4Length of stationary object
If multiple VHF communication base stations are deployed to extend coverage, then transmission distance increases, but system complexity and cost increase
Solution Approach 1:
The testing system evaluates coverage at different locations and identifies the minimum number of base stations required to achieve the desired coverage distance and call effect. By conducting comprehensive tests with temporary stations, the system determines the optimal deployment quantity - neither too few to miss coverage requirements nor too many to increase unnecessary cost and complexity. This partial action approach tests only the necessary configurations rather than all possible base station combinations.

AI summary
The present application provides a method for testing the coverage effect of a VHF communication base station, including: a server sending preset test parameter information to a mobile station, sending a first start test instruction to the mobile station and at least one base station, and receiving first audio data and first location information sent by the at least one base station, and second audio data and second location information sent by the mobile station. By using the mobile stations to send or receive audio data at different distances to a temporary VHF communication base station, it is possible to accurately determine a coverage distance of the temporary VHF communication base station and a transmission effect of the audio data at different communication distances.
