What is a data concentrator? ›

A data concentrator is the core of data and energy management in an AMI. It provides the technology to measure and collect energy usage data. The concentrator can also be programmed to analyze and communi- cate this information to the central utility database.

A device that merges many low-speed asynchronous channels into one or more high-speed synchronous channels to achieve economies of data transmission.

Data concentrators are used to concentrate the communication and management of a set of smart meters into one single device, facilitating the gathering of the information from the smart meters, grouping the communications to them, and therefore reducing the cost of the overall operations.

DCU collects analog, discrete and digital data from various avionic and aircraft systems. DCU accomplishes necessary measurements, computations and any logical operations then presents concentrated information to use of avionics and aircraft systems with analog, discrete and digital communication.

Overview. AEC's Data Concentrator Unit (DCU) is the backbone of Advanced Metering Infrastructure (AMI) that helps in data acquisition, transfer of energy data to the central database, and automated meter reading in electronic energy meters. DCUs are primarily used in low voltage electric power systems.

A hub (sometimes referred to as a concentrator) is to a network device which receives a data packet from one network node and retransmits to all other connected nodes.

A virtual private network (VPN) concentrator is a type of networking device. It lets you create secure VPN connections and deliver messages between VPN nodes. As such, it is essentially a router but is built specifically for creating and managing VPN communication infrastructures.

Hubs, which are also referred to as concentrators, are found in local area networks. These products serve as network hardware devices with ports providing connectivity to computers, printers and other peripheral hardware for the exchange of information.

Data Concentrator Unit (DCU) is an intelligent unit used to acquire data from multiple meters in a substation. DCU supports DLMS/COSEM protocol and can acquire data from a maximum of 20 meters. It is compatible with the meters manufactured by majority of Indian meter manufacturers.

The concentrator digitizes your voice at a sample rate of 8,000 samples per second and 8-bit resolution (see How Analog and Digital Recording Works for information on digitizing sounds).

What is data concentrator in substation? ›

A data concentrator is a software and hardware solution that connects a number of data channels with one destination. Data concentrators are found within substations to help manage many different data sources at one main source.

DCU provides a wide variety of services to consumers and businesses: Consumer banking and lending services – including checking, savings, mortgages, equity loans, auto loans, credit cards, and much more.

If the electrical system were regulated to 12 or 24 volts, the battery would not recharge during flight. A 28-volt system is generally more efficient than a 14-volt system because the same amount of electrical power can be carried in smaller wires. Remember, usable electrical power is the combination of volts and amps.

VMO/MMO means maximum operating limit speed. VMU means minimum unstick speed. VNE means never-exceed speed. VNO means maximum structural cruising speed. VR means rotation speed.

COPS-TARA DCU (Data Concentrator Unit) is a communication device to transfer meters data to control center for real-time access. DCU collects data from meters using MODBUS/DLMS standard protocol and sends to control center over OFC/Wired Internet/GSM/GPRS/3G/4G networks in real-time basis.

The DC Universe (DCU) is the fictional shared universe where most stories in American comic book titles published by DC Comics take place.

Starting at the forefront of a network, either next to or beneath a firewall, a VPN concentrator works by establishing multiple encrypted tunnels between remote employees and a centralized network. The VPN concentrator has employees' IP addresses and web traffic travel through these tunnels before reaching the network.

The concentrator works similarly to a VPN, but on a larger scale. It also encrypts data and web traffic. In addition, the concentrator tunnels data using security protocols. The major difference between a VPN concentrator vs VPN server is that the former is rarely used in private settings.

A VPN concentrator is a hardware device that creates and helps to manage multiple VPN connections remotely. Similarly to a VPN, it encrypts outgoing and incoming data and uses security protocols to create safe tunnels, but on a larger scale.

Most portable oxygen concentrators last between 4 to 7 years. The lifespan of a POC also depends on how well the patient takes care of their portable unit. It's important to regularly clean and maintains a device. This will help improve how long the machine lasts.

Do and don'ts for oxygen concentrator? ›

DO keep your device away from bodies of water and be aware of the weather. Don't allow your oxygen concentrator to get wet. DO keep your portable oxygen concentrator in a well-ventilated area. DO NOT leave your oxygen equipment in a vehicle when not in use.

They are wired routers, wireless routers, core routers, edge routers and VPN routers.

The Concentrator is the communication bridge between the core sensing units and main station of InHand Wireless Overhead Line System.

There are three types of network hubs: passive, active, and intelligent. network. They do not improve the performance of local area networks (LANs), and may limit maximum media distances. Typically, passive hubs are connected to other devices in a star configuration.

Home oxygen concentrators can run 24 hours per day. Portable units are sometimes not appropriate for sleep if they only deliver pulse flow oxygen. Check with one of our Oxygen Specialists regarding your oxygen needs before purchasing a unit for continual use.

A hub is a physical layer networking device which is used to connect multiple devices in a network. They are generally used to connect computers in a LAN. A hub has many ports in it. A computer which intends to be connected to the network is plugged in to one of these ports.

They pull together hardware, software, and connectivity and then organize it into four layers: field instrumentation; programmable logic controllers (PLCs) and remote telemetry units (RTUs); communications; and the SCADA host platform.

➢ DCS is process state driven, while SCADA is event driven.

SCADA is a bit more advantageous in this aspect, as it lightens the load of the host. Changes are also recorded much earlier, as an event is logged as soon as a value changes state.

Next you'll need to purchase a specialized jack, such as Cell2Jack. This little device is designed to connect any landline phone to a cellphone. You'll plug your home phone into Cell2Jack's phone port and plug Cell2Jack's other end into a USB port.

What can I do with old phone lines in my house? ›

First, either remove the box altogether, or cut the wires and tape up the ends with electrical tape so they don't touch each other. Or, even better, trace the line to its source and remove/disconnect the entire wire. Then you can patch the wall with this tried and true method or a wall repair kit on Amazon.

Inogen portable oxygen concentrators vary in cost, ranging from $2,651 to $3,586, depending on the battery (single or double) and warranty you select.

Substation automation can be structured into three levels: process, bay and station-level automation. At the process level, information from the sensors in the substation is extracted and transferred to an upper-level device called the bay-level device.

With 400 Hz, airplanes require fewer generators or alternators to produce a sufficient amount of power. This reduces their total weight, thereby making it easier for airplanes to take off. If airplanes used a lower power frequency, they would require more generators or alternators, thus increasing their total weight.

So for the short distances involved in aircraft, and the advantage of smaller and lighter transformers, motors and filter capacitors, 400Hz was adopted, particularly for military aircraft: MIL-STD-704F states: “Equipment designed for use on military aircraft should not use 60 Hz power, since it requires more weight and ...

Why 115v is used in aircraft? ›

Running at 115v 400Hz allows the use of smaller transformers. Less energy has to be stored in the transformer core per cycle, so the core can be smaller. A smaller core means a lighter transformer, and reducing weight is a good thing in an aircraft.

Anterior knee pain (AKP) is a common musculoskeletal complaint. It has been suggested that one factor that may contribute to the presence of AKP is a delay in the recruitment of the vastus medialis oblique muscle (VMO) relative to the vastus lateralis muscle (VL).

Exceeding either Vmo or Mmo will result in the activation of an aural warning (clacker). As an example, the diagram shows the flight envelope for the 757-200. Notice that below approximately FL270, the airplane is Vmo restricted to 350 KIAS. Above approximately FL270, the airplane is Mmo restricted to 0.86 Mach.

VMO is a structural limitation ( not to broke a part of the airframe, say for ex. the windshield) and is increasing with altitude, and MMO is an aerodynamic limitation (not to get supersonic on wings) and does nor vary. Hope it helps! Warning Toxic!

DCUs (Data Concentrator Units) are Intelligent Devices which are the backbone of Advanced Metering Infrastructure (AMI) that helps in data acquisition, transfer of energy data to the central database Head End System (HES) and Automated Meter Reading (AMR) in electronic energy meters which employ Radio Frequency (RF) ...

Phasor Data Concentrators (PDCs) are devices which aggregate and time synchronize (or time align) phasor data streamed from Phasor Measurement Units (PMUs) from across the grid. A PDC is a critical link be-tween the PMUs which collect the phasor data and the synchrophasor applications which use the data.

The SCADA systems are of four types are Monolithic SCADA system, Distributed SCADA system, Networked SCADA system, and IoT SCADA system.

Smart Meters generate both radio frequency (RF) radiation and electromagnetic field (EMF) radiation. This "electrosmog" is an extremely hazardous environmental pollutant responsible for many health problems.

All smart meters use a national wireless communication network to send information to your energy supplier. So, even if you do not have an internet connection in your home, a smart meter will still work.

There are two main types of smart meters - the older models known as SMETS 1 (Smart Meter Equipment Technical Specifications) and the newer versions that were rolled out in 2018, known as SMETS 2. This specification is more advanced and meters were first rolled out in 2018.

What is the difference between PMU and PDC? ›

The Phasor Measurement Unit (PMU) is a device that allows synchronized measurement of the voltage and current of electrical systems in microseconds. The PMUs are installed in substations of the power system and their measurements are sent to be processed by the Phasor Data Concentrator (PDC).

A phasor measurement unit (PMU) measures the phasor values of current and voltage. These values get a high precision time stamp and together with the values of power frequency, power frequency change rate and optional binary data that are also time stamped are transmitted to a central analysis station.

One good use of phasors is for the summing of sinusoids of the same frequency. Sometimes it is necessary when studying sinusoids to add together two alternating waveforms, for example in an AC series circuit, that are not in-phase with each other.
