In such scenarios as urban gas pipelines, petrochemical production and underground work in mines, leaks of flammable gases such as methane remain a major threat to safe production. Once monitoring is delayed and early warning is not timely, safety incidents, such as explosions and fires, are highly vulnerable to irreparable loss of life and property. With the development of product networking and sensory technologies, combined with high-precision, low-energy and intelligent flammable gas detection equipment, it has become a central support for the mitigation of gas spill risk from source sources in all areas, moving gas safety monitoring from traditional manual inspections to all-weather, intelligent precision control。
This flammable gas detection terminal was designed, constructed and fully process-tested in strict compliance with the standards of the gb/t 3836. 1-2021 and gb/t3836. 2-2021 national explosive environmental equipment, and is a low-energy, wireless intelligence terminal that collects flammable gas concentrations and monitors the gas pressure of the pipe. The equipment is designed for blast-proof containment, with a level of protection up to ip68 (1m/1h), an integrated structure with easy to install, maintain, operateable features, as well as the advantages of measuring high accuracy, low utility, high repetitiveness, etc., to adapt to a variety of complex industrial conditions and to achieve continuous, reliable, round-the-clock monitoring of flammable gases。
Laser sense core technology, solid foundation for accurate monitoring
Monitoring accuracy is the core performance of the flammable gas detection equipment, which carries the methane laser sensor using the vcsel chip on the sensory end, achieves the dual properties of low power consumption and high reliability from hardware sources, and significantly improves monitoring accuracy. The equipment uses laser detection principles and diffuse detection methods, with methane measurements covering 0-100 per cent of lel and measuring errors of only > 3 per cent fs, capable of accurately capturing minor changes in methane concentrations in pipes and effectively reducing leakage errors。
Compared to traditional detection equipment, laser sensor technology makes the equipment more sensitive to gas leaks, allows timely capture and feedback, even at trace concentrations, and provides accurate and reliable data support for subsequent emergency disposal, leaving the potential for gas leaks intact。
Super-low-working craftsman's heart design suitable for long-term continuous monitoring needs
Monitoring points in industrial production and municipal management networks are often widely distributed and part of the sites are located in remote areas, under-well environments, which place high demands on the continuity and durability of detection equipment. The detection terminal, which is powered by 3. 6 vdc lithium batteries, achieves a very low level of static power consumption of 50ua*3. 6v and dynamic power consumption of 50 ma*3. 6v in terms of power consumption control, with equipment having a useful life of more than three years。
Long-acting continuous flight capabilities make it possible for equipment not to replace batteries frequently, perfect adaptation to the long-term continuous monitoring needs of flammable gases in various areas, maintaining stable operation even at more difficult monitoring points, significantly reducing later manual maintenance workloads and allowing for regularization and continuity of gas monitoring。
Multi-module communication to achieve remote smart security control
This detector terminal has been enabled to manage the remote transmission and intelligence of monitoring data with the help of the technology of networking. Equipment supports three modes of communication: 4g, nb-iot, bluetooth. Data acquisition and dispatch cycles can be configured flexibly according to actual on-site needs. Monitoring of critical information, such as gas concentrations, pipe pressure, battery power, etc., can be uploaded to data centres in real time, and staff can see the operational status of terminals through web pages and mobile phones。
At the same time, the equipment is equipped with a well-established mechanism for the alarm of anomalies: once the gas concentration exceeds the pre-set threshold, the equipment will report unusual information without delay, leaving the staff member with the risk of leakage at first sight; and battery power below the threshold will automatically alert and alert the personnel of the transport to handle it in a timely manner. This design has shifted gas monitoring from traditional “on-site” to efficient “telecontrol” and has significantly improved emergency response efficiency and made security management more proactive。
Flexible expansion of functionality, one-stop matching multiple scene monitoring needs
This detection terminal is not a single-function monitoring device, but rather has a very high functional outreach. Based on the achievement of core flammable gas concentrations and pipe pressure monitoring, sub-well spot monitoring, well cover state monitoring and spill monitoring functions can be expanded according to actual needs, so that an equipment can meet multi-dimensional, multi-species monitoring needs and create one-stop on-site safety monitoring solutions。
The multifunctional extension design has resulted in a significant increase in the suitability of equipment, without the need for separate equipment for different monitoring needs, both to simplify the installation of on-site security monitoring systems and to reduce the cost of equipment input. Whether it is a combination of urban gas pipelines, multiple hazard monitoring of mining operations, or on-site security control of petrochemical sites, the equipment can be adapted flexibly to demand and become a practical support for security management in all areas。
Hard nuclear protection configuration to respond to complex field conditions
Industrial and municipal gas monitoring environments are often complex, with high temperatures, low temperatures, damp, flammable and explosive, and this detection terminal, with its rigid nuclear parameter configuration, can easily cope with all kinds of bad conditions. The work and storage temperature of the equipment are covered by -40°c ~ + 70°c, with a relative humidity of 0% - 100% rh, which can remain stable even in extreme, very hot, high-humid environments; the blast-resistant level of ex db iic t6 gb, which meets high national standards and can be used safely in an explosive environment; and the high protection level of ip68, which provides the equipment with an excellent waterproof and dustproof capability to cope with the high dust and damp field environment, such as underground wells and outdoor open air。
At the same time, the equipment is equipped in a wall-mounted form, in a robust structure that is able to withstand minor environmental disruptions on the ground, whether by an outdoor gas pipeline, under a closed wet mine well or a flammable and explosive petrochemical production area, and ensures the smooth operation of on-site monitoring。
Installation of maintenance easy access, significantly lower use threshold
In order to optimize the monitoring performance of the equipment, the installation of the detection terminal is subject to strict compliance with national standards gb50493-2009: the location of the installation is to be selected at a potential spill point or gas concentration site, it is proposed to be installed at a distance of 1 m at a site where there may be a gas leak, taking into account such factors as air flow speed, direction, ventilation conditions, etc., and it is prohibited to be installed directly on the heat or vibration sources. When installed, it is only necessary to ensure that the sensor is directed downwards to maximize the protection of the equipment from dust and water, and to complete the walling and efficient operation with the associated conventional installation tools。
The day-to-day maintenance of equipment also does not require complex professional operations, but only periodic inspections of whether the equipment is loose, falls, damages, etc., and detection of unusual and timely disposal; and regular cleaning of impurities, alien objects adsorbed at the bottom of the sensor, ensuring sensor-based monitoring accuracy, which allows common transport personnel to operate on hand, significantly reducing the threshold for the use and maintenance of the equipment。
Strict rules of use to prevent human security risks
As a specialized monitoring equipment for flammable explosive environments, there are clear safety norms for the use of this detection terminal, which need to be strictly observed in order to ensure the safety of the operation of the equipment and the safety of on-site production. The opening of detection terminal caps at operational sites, hazardous sites and the replacement and dismantling of battery assemblies in such areas are strictly prohibited; any operation within the equipment, maintenance work and the dismantling of sensors must be carried out by specialized technicians, and it is prohibited for non-specialists to take out their own maintenance and repair; before the instrument is powered, it is necessary to check carefully whether the connection is correct and to avoid failure of the equipment as a result of failure of the connection; the lithium cells used in the equipment are non-chargeable batteries and should not be self-charged with batteries; and, at the same time, equipment may not be installed in situations where there are strong corrosive gases, large quantities of dust, or direct vibrations and shocks。
Gas safety is everything, and safe production is the bottom line of development in all areas. This smart flammable gas detector integrates laser sensor technology, material networking technology, and ultra-low power consumption design to allow for more efficient and intelligent monitoring of the safety of flammable gases, with precision monitoring performance, stable performance, intelligent remote control and multiple adaptation capabilities. Its application in various fields has not only contributed to the upgrading of flammable gas monitoring technologies, but has also provided practical technical options for the mitigation of gas spill risks in more industries and the establishment of safe production lines, which are important underpinning gas safety monitoring in industrial production and municipal transport。
