Rigid Logic

Abstract Managing the distribution of water resources for the southern regions of Russia is of great importance in connection with limiting the consumption of fresh water. The use of saline water can lead to soil salinization and negatively affect crop production. The article deals with the problem of constructing a sequential automaton for controlling the system of switching networks when watering plants on the example of the sanatorium “Rus” in the city of Anapa, Krasnodar Territory. The Mediterranean zone, where the city of Anapa is located, is characterized by a low level of precipitation, which leads to the need for artificial irrigation of plants. The existing irrigation system using a water tank truck based on the GAZ-53 is physically outdated, which required the development of a modern automated system. The flower alleys, located on the territory of the sanatorium, were structured in a tree-like form. The construction of a control device based on rigid logic is based on the Mealy automaton. A method for constructing a control system for a tree-like water supply network has been developed, which makes it possible to control the main, distribution and supply branches. A block diagram of an irrigation machine has been developed, which has a tree-like branching, which shows control signals and states of transitions. Synthesized logical equations for the control of the water supply system, using a blocking control system with feedback. It is proposed to use the Omron programmable logic controller and CX-One software as software and hardware. The distribution of the address space of the controller is shown. Simulation modeling of the system operation was carried out, which showed the correct logic of control over the work of water pressure supply in water pipelines. Implementation of the developed system will improve the quality of irrigation of plants and minimize the cost of irrigation.

AbstractIn order to ensure better availability of water resource to different users, we undertook a dependability study of system for drinking water supply. A real case study was done on the water supply network in the city of El Hadjarin Algeria. We started from the site modelling, which provided a calculation of a Hydraulic Criticality Index (HCI) in order to prioritize the importance of pipes in the network. Once the indices were calculated, a modelling procedure of reliability block diagram was applied. The objective was to study and analyse the existing network to measure the water availability problems and try to provide viable solutions. An action on the structural aspect and hardware may be required in order to ensure better availability of water and make the system more reliable. Spatial modelling is also proposed to be able to monitor different parts of the network where problems may occur.

Pump Stations

In this article the tasks of modeling the flow distribution are considered, and since the consumers of this system are pumping stations, the first place is put forward not social (as in the second rise), and economic (energy) criteria. The water pressure at the pump inlets is determined by the geodesic levels of the pumps. In wells can be installed various pumping equipment, different in pressure and performance, resulting in a significant difference in the pressure produced by the pumping equipment. In the wells can be installed various pumping equipment, different in pressure and performance, as a result of which there is a significant difference in the pressure generated by the pumping equipment. The article presents a transformed version of the nonlinear and linear models of operational management as applied to water-lifting stations. The governance model allows tracking the transition of the system to a new state and the change of parameters along individual lines within this transition. Herewith, if from two wells the water supply to the manifold increases in accordance with a given forecast, then from the third - the water supply decreases. According to the results of modeling of water supply stations can be built throttle characteristic. The synthesis of throttle characteristics obtained on the basis of the operational control model allows for the operational control of the water supply modes to the clean water tank, which is an alternative to direct modeling. Both methods can be implemented as part of the operation of automated control systems for pump stations I and II lifting. The most interesting is the scheme of water supply stations without back pressure with the predominant location of wells with less powerful submersible pumps closer to the area of low pressures in the collector nodes. The results of numerical simulation are presented in the form of throttle characteristics, that is, the dependence of the flow rate of water supplied from a well by a submersible pump through a choke, on its hydraulic resistance coefficient. Due to the throttle characteristics, it is possible to determine the extremely high value of the water flow entering the clean water tank, as well as the possibility of modeling the most economical mode of operation of wells.

Abstract— Currently the world suffers from water scarcity, being one of the most frequent problems that agriculture suffers, there is still no uniformity regarding the extent of the planet covered by these dry lands, varying the calculations from close to 50% to 25% of the earth's surface. Africa and Asia being the continents that had the largest extensions of drylands. Therefore, this research work has as objective the Design of an Irrigation System using a Motor Pump for Desert Areas in Department of Piura - Perú and thus contribute to the agriculture of our country, as well as main points we will focus on the towns far from the city which will use automatic irrigation means through a natural reserve water supply which would have to be stored and through a drip system it will be possible to irrigate and optimize the water in order to give it a better use. Resulting in a water reservoir that once filled to 100% will begin to pump water through a motor pump and through pipes it will be transferred to another reserve reservoir to irrigate a desert area through a drip system so the reservoir plays an important role which will have available water without depleting given greater access to irrigate the land.

Abstract Bechar, a typical Saharan city with an arid climate, receives an average annual rainfall of around 72 mm. Two resources ensure the supply of drinking water to the city of Bechar; the first comes from a catchment field consisting of eight boreholes, and the second comes from the Djorf Torba dam located in the west at about 45 km where is located the drinking water treatment plant. Water scarcity and water supply disruption have caused residents of Bechar city connected to the water supply system to invest in relatively expensive storage and pumping facilities to meet their domestic needs. The survey was conducted on a sample of 20% of the population of Bechar city in a period of 4 months. Through the survey, we have reached that 74% of citizens of Bechar city are not satisfied with the quality and quantity of water and 59% of respondents are not satisfied with the water pressure and are therefore forced to use the pumps.
