Supports GPRS SMS reception feature, with optional data viewing via WeChat and mobile app.

Section 2: Primary Functions of BHG-SF6

A. Customer-centric service

1. Utilize Voice Report System: Before operators enter the work area, the system automatically reports the environmental conditions using an artificial voice. Operators are allowed into the work area only after 15 minutes of ventilation in a safe condition.

2. Equipped with a domestic 10-inch color touch screen: real-time display of various parameters and system status, with large, clear text and easy, simple operation.

3. Utilize Human Recognition Technology: The screen automatically illuminates when the operator enters the recognition range. The system automatically turns off the backlight after the operator stops operation to conserve energy.

4. Utilizes a suspicious detection node self-reinforcement tracking algorithm, while operators can also adjust the system inspection intervals according to actual needs.

5. Features a wide operating voltage design of 85-265V, with surge and lightning protection capabilities. Capable of adapting to various harsh environments.

6. Overlimit alarms are activated through voice, whistle, and alarm light in multiple ways.

Excellent performance

This system can simultaneously monitor gas concentration and oxygen content.

2. This system features the ability to self-set oxygen and concentration alarm points:

3. This system features manual forced ventilation and timed ventilation, with the timed ventilation schedule adjustable according to actual working conditions. Additionally, it allows for checking the last ventilation stop time.

4. This system features over-limit gas concentration alarms, voice prompts, and automatic ventilation.

5. This system features a real-time oxygen deficiency alarm function.

6. Each detection unit in this system can operate independently, capable of simultaneously detecting SF6 and oxygen leaks.

7. This system automatically activates timed exhaust ventilation and automatic exhaust for over-standard leaks, manual exhaust, and prompts for the last exhaust time.

8. The system can automatically detect the ambient temperature and humidity.

9. The system can be expanded to accommodate any number of gas detection points as needed, up to 64 in total.

10. This system can be connected to a higher-level computer to enable remote monitoring and record events and historical data.

11. This system supports historical data query functionality.

12. This system supports remote telemetry and remote signaling for the remote control system, as well as RTU telemetry and remote signaling functions.

C. Peace of Mind Maintenance

The system employs a long-life, high-stability detection solution design, ensuring the long-term stable operation of the detection unit.

2. This system utilizes original imported oxygen and SF6 gas sensors, with a sensor lifespan exceeding 10 years.

3. This system employs a ring network configuration for the detection units, facilitating installation and wiring.

4. This system employs an online automatic compensation and correction for errors caused by environmental changes, and automatically performs zero-point calibration. It resolves the common data drift issue found in similar products.

5. This system features an innovative daily automatic zero-point calibration function, which automatically corrects drift and false alarms.

6. Large-scale alarm data recording and storage capabilities, with long-life design.

III. Introduction to Main Components of BHG-SF6

The system is divided into three major modules: 1. Collector: Including temperature and humidity collectors and SF6/O2 collectors, primarily responsible for measuring temperature and humidity at various points and conducting quantitative analysis of SF6 and O2; 2. Main unit and auxiliary function module, mainly responsible for coordinating work among modules, displaying and alarming; 3. Fan controller, primarily for starting the fan.
