Description
Title of Invention : ONLINE DEVICE AND METHOD WITH AUTOMATIC CLEANING MECHANISM FOR SOIL CARBON
DIOXIDE MEASURING
Technical Field
[0001] The technical field of the invention relates to environmental pollution online monitoring devices in farmlands.
Background Art
[0002] An invention filed in Korean patent office by 1020080122925 application number named "DEVICE FOR MEASURING CARBON DIOXIDE, CAPABLE OF ENHANCING THE ACCURACY AND THE RELIABILITY OF THE CONCENTRATION MEASUREMENT OF CARBON DIOXIDE". A device for measuring carbon dioxide is provided to prevent a heat radiating pattern from changing due to a high temperature driving and to stably measure the concentration of carbon dioxide by supplying a constant driving temperature. A device for measuring carbon dioxide comprises a carbon dioxide (C02) sensor, a heating unit, and a electromotive lead wire.
[0003] The carbon dioxide sensor comprises solid electrolyte, a reference electrode and a sensing electrode. The reference electrode and the sensing electrode are formed on one or both sides of the solid electrolyte. The heating unit comprises a ceramic substrate at one side of which a heater is formed. The lead wire is extended to the reference electrode and the sensing electrode. The heating unit includes one or more diffusion preventing layers wrapping the reference electrode. The diffusion preventing layers are composed of metal, oxide or their mixture.
[0004] The main difference of this device from the claimed invention is in equipment and instruments. At the same time, it lacks automatic cleaning system. On the other side information are not transmitted online by this device and some other differences will be presented following.
Technical Problem
[0005] The magnitude of the benefits of being able to measure C02 flux in soil is revolutionary. The reduction of carbon levels in the atmosphere is one of humanities most pressing needs and Carbon sequestration is one of the most effective ways of reducing carbon levels in the atmosphere.
[0006] Controlling the level of C02 that is in the atmosphere is one of the biggest problems facing humanity. C02 sequestration is one of the most efficient and ready to use solution that can help deal with the toxic levels of C02 being produced daily. Despite all of this, C02 stocks in soils across the globe have been steadily decreasing over the past decade and risk becoming depleted in the not so distant future. One of the major sources of atmospheric C02 emissions is agricultural activities which produce as much atmospheric C02 as heavy industries. - Private stake holders - Carbon flux from soil is an indication of the fertility of the soil and its effective potential output for agricultural activities.
[0007] - The current problem with the measurement of C02 flux in soil is the cost, with the entry level measurements systems that cost nearly 5,000 USD per sensor. It becomes economically unfeasible to deploy many theses sensors. Neither the public sector nor the private agricultural sector can afford to utilize this technology effectively.
[0008] - The difficulties in accurately measuring the C02 flux make it very difficult to set caps in e.g. Commission trading schemes (Carbon Trust, 2009) and pose a major challenge against the emergence of trading schemes around the world that are based on C02 flux.
[0009] - There is currently no system in place that allows for the collection of C02 flux to be stored using block chain technology, which would be instrumental in providing assurances that would be the basis of future trading schemes across the world.
[0010] This system will provide a carbon flux observing and analysis system at a fraction of the cost of similar sensors. The sensor price is set at 1 ,500 CAD, which is nearly 77% below that of the nearest competitor. In addition to this significant pricing advantage, some of the key functionalities of this inventions system are currently unparalleled:
[0011] None of the sensors in the market use NB-IOT (narrow band IOT) to establish a network between the sensors. The system of this invention will do that and send all the information to a centralized software that will store it using blockchain technology.
[0012] The sensors will provide real time readings on a constant basis related to (i) temperature; (ii) humidity; (iii) atmospheric pressure and (iv) carbon PPM detected by its gas chamber. This information is presented in the form of graph for the user.
[0013] The sensors will have a solar-battery rechargeable system that will allow them to operate approximately 5 days in the complete absence of sun. The centralized application provides information on the battery status of each sensor as well allowing the replacement of the battery of the sensors that have stopped working.
[0014] The information collected will be analyzed using systems similar to SPLUNK, that allows the analysis of machine-generated big data.
Solution to Problem
[0015] We have devised a sensory system to effectively measure the flux of carbon from soil. The system is fully automated, operate on solar energy, and collect information in a real time constant manner over a long period of time. The system in question will link all the sensors deployed over a land through NB IOT technology, and the collected information will be stored through blockchain technology and further analyzed using analysis systems for machine generated big data, such as SPLUNK.
[0016] To precise C02 assessment, an innovative approach was applied to get the best results. To satisfy this end, air enters the internal part from the device's bottom. Subsequently, it is transferred to a chamber in which all the sensors are positioned. Indeed, assessment of C02 flux and other variables is performed in this place. Then, by a solenoid valve and air pump, the air that existed in the chamber is exited and fresh air is entered into the device and the same cycle will begin again.
[0017] As per this approach, there will often be fresh air within the instrument and the prior air (both more polluted or cleaned) will not influence the next information monitoring.
