SMART BIO AQUA MONITORING SYSTEM (SBAMS) INTRODUCTION 1.1 REALITY OF GROWING SHRIMP IN VIET NAM Viet Nam is a country with 3260 Km of beach Especially, in south of Viet Nam has a high density of river web and the warm climate suitable for growing of shrimps during all seasons of year Shrimp farming has a big advantage for exporting and bring good benefits for country Shrimp farming has achieved significant steps for developing both quantity and quality in recent years and contributed huge benefits in making jobs and increasing income for farmers and developing vietnamese economy In recent years, with unpredictable increasing mumber of disasters since climate change like salinity intrusion and long time of drought have affected seriously to MeKong delta Coming with old technology and technical farming make lots of dificulties for aquaculture and also shrimp farming 1.2 DESCRIPTION OF THE WHOLE SYSTEM 1.2.1 Purpose With solution in need, we developed a system include IoT solution for feeding, monitoring and fixing environment for aqua-farm A system can operate automatically with green energy from solar system By using internet, farmers can control the system to feed the shrimps and monitor their farm distantly Since that farmer could low down costs for growing shrimp, risk from desasters and increase quality of product System is a floating boat include monitoring system, feeding system, dynamic system and power system It takes responsible for feeding and taking care of environment in a modern shrimp aqua farm The system will monitor environment inside water of aqua farm by using sensors, camera and save the data to cloud in graph by using internet 1.2.2 Indexes need to analyze The system need to monitoring the environment inside shrimp farm such as pH index, Dissolved oxygen and temperature pH ( power of Hydrogen): pH is a index specify the acidity or basicity (due to the amount of H + ions concentration) of an aqueous liquid An aqueous has the pH index less than is acidic and the pH index greater than are basic The neutral value of the pH depends on the temperature, being lower than if the temperature increases Pure water is neutral, with pH value approximately at (25 °C) The pH value can be less than or greater than 14 means that being very strong acidic or strong basic In shrimp farms, changes in pH value can affect to physical and Bio health of shrimps: - pH = 7.2 to 8.8 is the appropriate water environment for shrimp The best condition is between 7.8 and 8.5 pH should not fluctuate higher than 0.5 in shrimp ponds during a day If pH value changes significantly, it causes shrimps shocked, weakened and stop eating - If the worse pH environment happend for a long time, shrimps are growing slowly, stunted and susceptible to diseases Dessolved oxygen: Dissolved oxygen (D.O) is an important factor in shrimp aqua farm Low dissolved oxygen in the water can cause deaths to shrimps Oxygen concentration changes depending on the depth of water, the deeper water height is, the lower oxygen water has Dissolved oxygen changes when temperature and salinity change Temperature: Shrimps are cold-blood species (poikilotherm) Their body temperature depend on the habitat temperature Temperature significantly affects to shrimps respiration, food intake, assimilation of food, immune system and growth Since the day heat of water surface, thermal stratification occurs: there is differences with the weight and absorbent between layers of water make them hard to mix each other Thermal stratification can be controlled with paddle wheel or Aerator Temperature is lower than 15 degree Celsius or higher than 33 degree Celsius for 24 hours or longer causes death of shrimps Shrimp is suffocated at the temperature of 15-22 degree Celsius and 30-33 degree Celsius With the temperature of 23-30 degree Celsius environment is suitable for growing white legs shrimps However, small shrimps (1 gram) grow faster in warm water (30 degree Celsius) while large shrimps (12 – 18 gram) grow well at a water temperature of 27 degree Celsius Data intakes Coordinate: The system need to take coordinate frequently as longtitude and latitude for drawing the route, calculate the distance and point out the destination need to get for the boat The coordinate data also help to take the information of weather forecast from internet Orientation: The system need to defind the direction to support the movement The system will self-control the direction and get to the destination automatically SYSTEM DESIGN 2.1 SYSTEM PLATFORM 2.1.1 The whole boat The boat whose size is 2.75 meters long and meters wide Can contain more than 100kg by using main bouys and balance floating bouys strong gypsum plates are used for main base All the boat are strengthend by stainless bars On the boat, there are containers for contain main board of each part All components are strength attached by bolts and nuts Some waterproof parts are attached by silicone glue more than years With the size 1600x300x200 milimeters and 5.3 kg of weight 2.1.2 Components Main bouy: Main bouys are made from HDPE plastic with strong endurance, can last more than years With the size 1600x300x200 milimeters and 5.3 kg of weight Balance floating bouy: 10 litters plastic bottle is used for balance floating bouy, it supports for the floating of the boat and also used to make the boat balanced Main base: Main base is made from gypsum plate whose sizes: 1250x1250 mm and 1325x620 mm Stainless bar: Stainless bars whose size 2000x100 mm used for attaching and strengthening bouys Container: Container is a box that contail board and device in order to let system away from moisture 2.2 SYSTEM ARCHITECTURE 2.3 SYSTEM DIAGRAM Transmitter & Reciever Camera Monitoring Part (Take responsible for monitoring environment) BIO Part (Take responsible for feeding shrimps) LoRa Main Processor Take responsble for analyzing data and make commands) Internet Server Cloud Internet Control Part 2.4 MONITORING PART (Take responsible for Another Device controling dynamics) 2.3.1 and Camera, transmitter and reciever (Smart phone, personal computer) Camera Main processor Transmitter Receiver 10 Camera: Camera designed with the full functions of sport camera with high duration in environment and has water proof case can stand strong under pressure of 30 metters height of water Specifications: - 14 MP - F = 2.8 - FHD 1080p - inch LCD - Wireless Wifi - USB port - Water proof case Transmitter ( TS832 ): 10 19 All voltages are referenced to ground Logic one voltages are specified at a source current of mA Logic zero voltages are specified at a sink current of mA Active current refers to either temperature conversion or writing to the E2 memory Writing to E2 memory consumes approximately 200 µA for up to 10 ms Input load is to ground Standby current specified up to 70°C Standby current typically is µA at 125°C To always guarantee a presence pulse under low voltage parasite power conditions, VILMAX may have to be reduced to as much as 0.5V 19 20 To minimize IDDS, DQ should be: GND ≤ DQ ≤ GND +0.3V or VDD – 0.3V ≤ DQ ≤ VDD Under parasite power, the max tRSTL before a power on reset occurs is 960 µS DOP ( Dissolved Oxygen Probe): A galvanic dissolved oxygen probe (DOP) use anode bathed in an electrolyte, a polyethylene membrane and a cathode Oxygen molecules defuse through the probes membrane at a constant rate (the reaction occurs too quickly without the membrane) Once the oxygen molecules have crossed the membrane 20 21 they are reduced at the cathode and a small voltage is produced If no oxygen molecules are present, the probe will output mV As the oxygen increases so does the mV output from the probe Each probe will output a different voltage in the presence of oxygen The only thing that is constant is that 0mV = Oxygen (A galvanic dissolved oxygen probe can also be used to detect the Oxygen content in gases) pH probe : pH (potential of Hydrogen) probe measures the hydrogen ion activity in a liquid At the tip of a pH probe is a glass membrane This glass membrane permits hydrogen ions from the liquid being measured to defuse into the outer layer of the 21 22 glass, while larger ions remain in the solution The difference in the concentration of hydrogen ions (outside the probe vs inside the probe) creates a VERY small current This current is proportional to the concentration of hydrogen ions in the liquid being measured Converter: Electronics are the sensitive devices with voltage, like arduino can work under the voltage from to 9V and also another devices like sensors, motors but the battery always supply the voltage of 12 so we need a device can convert the voltage of 12 to 5v 22 23 LoRa LoRa is a embedded device that provides data transfer function It provides a long range distance use radio frequency communication This LoRa device use SX1278 Chipset, work on 433MHz frequency With the compact size 21x36mm, device can handle the distance 3Km Specifications: -
