Environmental Monitoring, Product Introduction
Gas is an important medium. It is used in closed medium and high-voltage switches to play the role of arc extinguishing and insulation. Gas is also a simple asphyxiant. The decomposition products of gas after high-temperature arc discharge include thionyl fluoride, sulfuryl fluoride, sulfur tetrafluoride, sulfur difluoride, etc., which are extremely harmful to the human body. The "Electrical Industry Safety Work Regulations" specifically stipulates that oxygen and gas online monitoring systems must be installed in relevant places, and necessary ventilation devices must be installed.
The environmental online monitoring and management system is a product specially designed to solve the above problems. This system uses original imported sensors to monitor gas concentration, ambient temperature and humidity, and oxygen content online in real time, and automatically controls the start and stop of the fan. The system automatically records various alarm data and real-time data, controls the fan according to the set method, can be flexibly configured according to the specific requirements of various applications, and provides an interface with remote communication devices to realize remote control, telemetry, remote signaling and other functions. This system can be widely used in switch rooms of various voltage levels, combined electrical rooms (rooms) and other places.
, Product Features
) Multiple detection functions
This system mainly detects gas concentration and hypoxia conditions, and also has auxiliary detection functions for environmental data such as temperature and humidity. It fully complies with the "Electronic "Industrial Safety Work Procedures" requirements.
) Ultra-low false alarm rate
This system software has been filtered to prevent false alarms and fundamentally solve the problem of system instability.
) Software and hardware can be customized
This system can flexibly customize the software and hardware of the transmitter function through external settings to adapt to the needs of different occasions and try its best to save costs for customers.
) Complete communication network
This system uses R communication method to build a suitable communication network for on-site detection of various data, and then transmits it to the central controller for processing, display and storage.
) Strong anti-interference ability
This system has fully considered the interference problem, and adopted a variety of effective anti-interference processing methods in the hardware circuit and software design to ensure the stable operation of the system. and the accuracy of measurement data.
Main functions
) Detect the concentration of gas in the environment. If it exceeds the alarm, start the corresponding fan at the same time
) Detect the concentration of oxygen in the environment. In the system settings, the oxygen alarm threshold can be set. , the setting value range is﹪, and the alarm for exceeding the standard will start the corresponding fan at the same time
3) The temperature and humidity threshold of the ambient temperature and humidity detection function can be set, and you can choose to start the alarm for exceeding the standard or the fan corresponding to the fan
) Large screen The blue LCD displays real-time detection data and historical data records. The historical data records include the recording and query functions of detection data, alarm data, the latest fan start time and other parameters
) Time setting (including Year, month, day, hours, minutes and seconds), oxygen alarm threshold settings, temperature and humidity alarm threshold settings, detection mode settings (including user mode, detection mode, where the detection mode is always detection), system configuration settings, gas transmitter settings, Environmental transmitter settings, fan working parameter settings, etc.
) It has the function of manually starting the fan, and the fan can be turned on or off through the switch button of the central controller
) When there is gas or oxygen exceeding the standard, the host's The alarm starts to sound and light, starts the fan in the corresponding zone, and immediately locates and displays the information of the alarm point
) When the person who wants to enter the scene is about three meters away from the display screen, the voice system automatically starts to prompt the person who wants to enter. Check the on-site parameters, automatically report the on-site parameters with voice, and display the status of each detection point through the screen, including gas, oxygen, etc., automatically determine whether the site is safe and whether personnel are allowed to enter
) Automatic zero-point calibration function, overcome drift and False alarm, and system self-diagnosis function
) The host has a self-diagnosis function, and the detection unit is ring-mounted for easy installation and wiring
