Description
Technical field
The present invention relates to gas ductwork monitoring field more particularly to a kind of gas ductwork monitoring sides based on narrowband Internet of Things
Method.
Background technique
With wideling popularize for national energy conservation and emission reduction policy, natural gas due to advantage clean, conveniently, high-quality, efficient,
Effect in energy resource structure will be more and more important.Therefore, the monitoring of fuel gas conduit is also become more and more important.
Present gas ductwork monitoring device mostly uses functional module combination to piece together mode, such as data transmission device (DTU)
+ data acquisition unit+transmitter+sensor mode.And this kind of device has the disadvantage that product integration degree is not high, so that
It influences the stability of product and increases product engineering enforcement difficulty, product causes the enforcement difficulty on gas ductwork to increase, even
It can not implement.Number leaflet member is generally 2G, 3G wireless transmission unit, and non-the whole network leads to mould group, and deployment is implemented to be limited to communication base station
Distribution, deployment is implemented to be limited, moreover 2G frequency range will be closed gradually, the dedicated networks such as transference NB-IOT.There has been operator in the existing country
Gradually close 2G network.Signal conversion unit is generally single signal processing mode, such as 4-20MA signal.Signal transformation is general only
It supports 3 line interface sensors, 2 line interface sensors is also needed to convert again.Other turn also is needed for 0-5V signal
Circuit is changed, the sensor of general binding single type is generally designed for signaling interface, some do not have RS485 extension also
Port.Overall not to be able to satisfy the various demands of user, serious limit product is promoted and is implemented.Sensor is generally factory's direct-furnish
Sensor, after data processing unit receives signal, general no data correction process or be simple data processing.Product is real
Initial stage generally certifiable measurement accuracy is applied, the use time with sensor and product extends, leads to not effectively guarantee to produce
Product measurement accuracy, causes measurement error seriously to go beyond the scope, and product performs practically no function.The general non-transformer loop pipe of product power-supply service
Unit is managed, storage battery power supply is directly used, incompetent source control directly adds the mode of battery using alternating current.TCP data segment
Generally use customized agreement, agreement can not accomplish compatible management, user can not application extension, belong to dedicated system, apply
Relative closure.
The problem for the use of being primarily present two of pipeline network of fuel gas in city at this stage simultaneously: being on the one hand too early to in-service pipeline
Or excessively maintenance, it wastes huge；On the other hand, leakage, rupture occur due to not being maintained in time for some pipelines, cause
Therefore irremediable loss typically looks at the research reinforced to pipeline network of fuel gas in city risk assessment technology, with science, in fact
Qualitative, Quantitative Risk Assessment, and root are carried out to gas pipeline network system with, the methods of risk assessment that is widely recognized as by industry
According to corresponding safety management standard, a possibility that evaluation system is caused danger and its severity propose necessary measure to seek
Asking reduces contingency occurrence probability, reduces causality loss, formulates optimal security capital strategy, but disadvantage does not have in the process of running
Prior early warning.
Meanwhile the underground gas ductwork of China's most cities is generally by the way of artificial detection management, track walker
It carries portable detection equipment to detect gas pipeline and its attachment, when occurring to leak and reach a certain concentration, just
Alarm signal is issued, then carries out respective handling, this mode has certain flexibility and sensitivity, but this traditional leak detection
Mode over time and space there is many loopholes, as the gas leakage emergency event in night or scarcity location be not easy by
It was found that and since pipeline network of fuel gas in city is longer, the period of inspection is also very long, needs to put into a large amount of manpower and material resources.At present with
Being growing for city size, gas ductwork density be continuously increased, gas pipeline is the important energy source artery in city, have easily
Explosive feature is fired, factors cause to leak equipment is long neglected and in disrepair, road rolls etc., not only cause the very big of the national valuable energy
Waste influences civic normal life gas, while more coming to citizen's lives and properties and national wealth safety belt huge hidden
Suffer from.Therefore there are great economic benefit and society to protection personal safety as well as the property safety, energy saving resource to its effective management
Benefit.
