Solution for directional mobile phone signal shielding system in factory workshop
Optimizing production processes and safety control in modern factory workshops by providing precise zonal signal shielding and compatibility assurance.
Project Background
A large automobile manufacturing enterprise was facing efficiency and safety hazards caused by mobile phone usage in its production workshops. Employees using mobile phones in key production areas not only distracted attention and affected production efficiency but also posed potential safety risks. At the same time, the company needed to ensure normal communication functions in office areas, rest areas, and emergency communication facilities.
Challenges
- Mobile phone usage in production areas leading to decreased work efficiency
- Potential interference with precision electronic equipment from wireless signals
- Need to distinguish between shielded and non-shielded areas
- Harsh industrial environment requiring high equipment durability
- Requirement for remote monitoring and management capabilities
Solution
We customized a targeted zonal shielding and compatibility optimization solution specifically designed for the unique needs of factory workshops.
Utilizing high-precision directional antenna arrays to precisely control signal shielding range, applying shielding only to designated production areas while ensuring normal communication in office areas, rest areas, and emergency communication facilities remains unaffected.
- Multi-beamforming technology for precise target area coverage
- Adjustable shielding radius to adapt to different workshop layouts
- Edge signal attenuation design to minimize signal leakage
The equipment employs advanced electromagnetic compatibility design, ensuring that while mobile phone signals are blocked, there is no interference with precision instruments, automated equipment, and control systems within the workshop.
- Out-of-band rejection ratio >70dB
- Adaptive frequency adjustment to avoid sensitive frequency bands
- Real-time spectrum monitoring with dynamic transmission parameter adjustment
Equipment specifically designed for industrial environments, featuring excellent weather resistance and stability for long-term reliable operation under various harsh conditions.
- Operating temperature range: -30℃ to +65℃
- Protection rating: IP65 dust and water resistance
- Vibration-resistant design suitable for large equipment operation environments
- Corrosion-resistant materials adapted to chemical plant environments
Through a centralized management platform, remote monitoring, configuration, and maintenance of all shielding equipment are achieved, significantly reducing operational costs.
- Web-based management interface accessible anytime, anywhere
- Real-time status monitoring and fault预警
- Timing policy settings adaptable to different shift requirements
- Detailed logging and audit functionality
