In today's accelerating urbanization process, carbon monoxide in enclosed spaces such as underground garages and subway tunnels（CO）Concentration monitoring has become an important link in ensuring public safety. Launched by Yachuan TechnologyYC-PFAir quality controllers, with their precise monitoring, intelligent linkage, and energy-saving and efficient features, have become the core equipment for underground space environmental management. This article will analyze the core value of this controller from three dimensions: technological advantages, application scenarios, and user value.

1、 Technical advantage: Dual guarantee of precise monitoring and intelligent linkage

1. Real time concentration monitoring and multi-level alarm

YC-PFThe controller receives real-time signals through two bus communication technologyYC-CMWThe data from the carbon monoxide sensor has a monitoring accuracy of up to0.1PPMResponse time≤30In seconds. whenCOThe concentration exceeds the preset threshold (such as25PPM）At this time, the controller immediately triggers an audible and visual alarm, and through0-10VAnalog output or relay contacts（3ACapacity linked exhaust system. Its LCD screen can synchronously display the current concentration value, alarm status, and equipment operating parameters, supporting historical data query and fault self check.

2. Multi zone centralized management and flexible control

The controller adopts a passive node design, which can simultaneously manage sensors in multiple fire compartments. For example, in the underground garage project of Wanda Plaza, oneYC-PFThe controller is connected through a two bus network16A fire compartmentCOSensors dynamically adjust the fan speed based on the concentration values in different areas: start low-speed exhaust when the concentration is low, switch to high-speed mode when the concentration is high, to avoid energy waste.

3. Open interfaces and compatibility

Equipment reservationRS485/ModbusInterface andLonWorksNetwork module, seamlessly integrated into building automation system（BA）Or a smart city management platform. Simultaneously supporting fire alarm linkage input and fire damper status feedback, forming“monitor-call the police-disposal-feedback”The closed-loop management chain.

2、 Application scenario: Comprehensive coverage from underground garages to public buildings

1. Underground Garage: Dual Requirements for Safety and Energy Efficiency

According to the "Code for Design of Garage Buildings", the underground garage requires an hourly ventilation rate≥6Next time.YC-PFThe controller passes throughCODynamically adjusting the start and stop of concentration fans to achieve energy conservation in an underground garage project in a residential area in Xi'an30%Above, while ensuringCOLong term concentration below10PPMThe safety threshold.

2. Public Buildings: Standard for Green Building Acceptance

In large commercial complexes such as Wanda Plaza,YC-PFController and Multi in One Sensor（PM2.5TheCO₂TheTVOC）Collaborate to meet the requirements for indoor air quality in the Green Building Evaluation Standards. Its data upload function can provide real-time monitoring reports for green building acceptance.

3、 User value: Reduce operation and maintenance costs, improve management efficiency

1. Lower maintenance cost

The controller adopts a rail mounted installation, supports hot swappable sensor replacement, and reduces maintenance time to10Within minutes. Provided by Shaanxi Yachuan Intelligent Technology Co., Ltd8Hourly on-site response service to further ensure equipment stability.

2. Improve management efficiency

passBASystem interface, property management personnel can remotely monitor all partition data in the central control room and generate air quality reports with just one click. For example, a project in Kunming is centrally managed through a controller3An underground garage24Typhoon, reducing labor costs50%.

3. Meet compliance requirements

The equipment has passed the national fire electronic product testing and certification, and meets the requirementsGB 16806-2006Standards provide reliable assurance for project acceptance.

Conclusion: Solutions for Intelligent Environment Management

YC-PFAir quality controller“Accurate monitoring, intelligent linkage, open compatibility”As the core, it solves the pain points of single function, high energy consumption, and decentralized management in traditional solutions. Whether it is the safety protection of underground garages or the green operation of public buildings, this controller demonstrates its value as an intelligent environmental management. With the advancement of smart city construction,YC-PFThe controller will continue to safeguard the safety and health of public spaces.
