This document describes a proposed system to automate urban drinking water supply and identify leaks using Programmable Logic Control (PLC) and Supervisory Control and Data Acquisition (SCADA). The system would minimize human error, reduce water wastage from leaks, theft and faults in pipes. Sensors would monitor water pressure and flows. PLCs would control pumps and valves locally, while a central SCADA system would allow remote monitoring and control. Data from sensors would be transmitted to the SCADA system via RTUs to identify leaks and optimize water distribution in real-time. This could help reduce supply costs and more efficiently match demand with a scarce water supply in urban areas of India.

When the fire detector in its protected area is directly connected to the fire extinguishing controller, the alarm linkage control of each stage and the feedback signal of the system shall be immediately fed back to the fire extinguishing linkage controller, and the fire extinguishing linkage controller shall start the alarm linkage control process according to the specification requirements.
After the fire linkage controller receives the feedback signal, is it necessary to activate all the fire audible and visual alarms and fire broadcasting in the building? Is it necessary to turn on the smoke control and exhaust system and the emergency lighting evacuation indicator system?
Fire alarm and gas extinguishing system instruction
Gas fire extinguishing control system is mainly composed of gas fire extinguishing controller, fire detectors, manual /automatic switch, emergency start/stop button, sound/light alarm, gas spraying indicator light, etc.
Among them, Generally, smoke detectors and heat detectors are used as fire detectors.
Manual alarm button or other types of fire detectors can also be used in special cases.
Gas extinguishing controller linkage control gas fire extinguishing equipment, linkage control fan, Air valve fire valve, Ventilation and air conditioning, Automatic doors and Windows and other equipment. And receive feedback signals.
test of gas fire extinguishing system
The gas fire extinguishing system project requires the implementation of simulated start-up tests to verify the reliability of the gas fire extinguishing system. The simulated start test shall be carried out after the installation and debugging of gas equipment, alarm equipment and gas fire extinguishing equipment.
1. Manually start the experiment
2, automatic start test.
electric fire temperature detectors
Temperature measuring electrical fire monitoring detector can detect the change of temperature parameters in the protected line, and can monitor the abnormal temperature of the line or connection point.
The detector shall be installed in the key heating parts of the cable connector terminal.
Temperature measuring electrical fire monitoring and detection includes signal processing unit and temperature measuring sensor.
independent electric fire detection system
The independent electric fire monitoring detector has the function of monitoring and alarm, the detector sends out sound and light alarm signal when alarm, and displays the alarm value, which can be used independently.
When there is no fire control room and the number of electrical fire monitoring detectors is not more than 8, independent electrical fire monitoring detectors can be used.
Each signal processing unit of the independent electrical fire monitoring detector can equip up to 4 sensors.
When the automatic fire alarm system is provided, the alarm information and fault information of the independent electrical fire monitoring detector shall be displayed on the graphic display device of the fire control room or the centralized fire alarm controller.
fire alarm linkage smoke exhaust
The alarm linkage control of smoke control system refers to the alarm linkage control of mechanical smoke control system.
According to the different parts of the setting, the mechanical pressurized air supply system can be divided into the mechanical pressurized air supply system in the stairwell and front room, the mechanical pressurized air supply system in the refuge layer and the mechanical pressurized air supply system in the refuge aisle.
Mechanical pressurized air supply system in the stairwell and front room:
Linkage control should be divided according to fire protection zones, including automatic, manual, chain start and other control methods.
linkage fire alarm system parts
Fire alarm controller and fire linkage controller are integrated products, called the linked fire alarm controller.
The main components of the linked fire alarm controller include motherboard, display board, bus linkage control panel, multi-line linkage control panel, network interface component， power supply, loop board and so on.
addressable fire alarm system loop
Most fire alarm systems adopt two bus system.
Two bus is a bus technology that combines power supply line and signal line. Two buses save construction and cable costs, greatly facilitating on-site construction and later maintenance.
addressable fire alarm system bus loop
There are two main types of bus systems - tree bus and ring bus. Tree bus has a unidirectional loop that means equipment behind a fault cannot operate, while ring bus forms a closed loop so a single fault does not affect the whole system. Both require bus isolators to isolate faults without disrupting other equipment. The total number of devices protected by each isolator should not exceed 32. Isolators automatically reintegrate isolated sections once faults are repaired.
division of fire alarm areas
Alarm area is a unit that divides the warning range of automatic fire alarm system according to fire zone or floor. An alarm area includes a plurality of detection areas.
The purpose of dividing the alarm area is to determine the location of the alarm and fire. At the same time, it is convenient to solve the problem of fire control system linkage design.
The alarm area should be divided according to the fire zone or floor. You can also divide several adjacent fire zones or floors that need to be simultaneously linked with fire fighting equipment into an alarm area in case of fire.
addressable fire alarm bus short circuit isolator
Bus short circuit isolator is simply called bus isolator.
It is necessary to install bus short circuit isolator in bus automatic fire alarm system. When a bus fails, the bus isolator automatically separates the faulty bus part from the whole system to ensure the normal operation of the rest of the system.
At the same time, the fire alarm controller indicates the part number of the isolated parts, which is convenient for maintenance.
When the fault is rectified, the bus isolator automatically reintegrates the isolated part into the system.
fire manual call and hydrant button
Manual fire alarm button is a manual fire alarm device.
After the alarm button is pressed, the alarm signal is sent to the fire alarm controller through the bus loop.
The controller displays the position, code and annotation information of the alarm button, and sends out sound and light alarm signal.
The alarm button should be set with a red start confirmation light. After pressing the alarm button, the start confirmation light should be lit and kept until the alarm state is reset.
carbon monoxide detection system
According to the code, carbon monoxide detectors should be installed in places where carbon monoxide leakage is possible.
For the choice of carbon monoxide detector, you may have the following questions:
Carbon monoxide is both a combustible gas and a toxic gas，should I choose a carbon monoxide detector or a combustible gas detector?

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

fire alarm system fire graphic display device
- 1. According to the specification requirements, the centralized alarm system and the control center alarm system need to be equipped with graphic display device (CRT system). The graphic display device is installed in the fire control center, which is used to simulate the building plane layout of the fire trigger device and linkage device on site, and can truthfully reflect the fire, linkage condition and fault situation on site. The graphic display device can display the general layout of the building, the building plan of each protected object, the system diagram, and the names and evacuation routes of each protected object and the main parts. And can display automatic fire alarm and linkage control system and its control of all kinds of fire fighting equipment name, physical location and dynamic information of each fire fighting equipment. The graphic display device receives the fire alarm signal or linkage control signal issued by the fire alarm controller and the fire linkage controller. When there is fire alarm signal and linkage signal input, the graphic display device should be able to display the corresponding building location and building plan of the alarm part, indicate the physical location of the alarm part on the building plan, record the alarm time, alarm part and other information. The graphical display device can query and display the physical location and corresponding real-time status information of each fire fighting device in the monitored object system in the monitoring area. However, the graphical display device cannot reset the controller, set the system, and start and stop the linkage device.
- 2. Electrical fire monitor, fire door monitor, combustible gas alarm controller alarm information and fault information can be displayed on the graphic display device. However, the display of such information should be different from that of fire alarm information and should be connected by special lines. The graphical display device shall be capable of transmitting information remotely and receiving remote enquiries. There should be status indicators during the sending and receiving of remote queries.
