CIRCLE: Energy Data Collection Cabinets

2019

Purpose, Functions and Components of Data Collection Cabinets

According to the company NPF Krug, the basic element of data collection cabinets (ShSD) is the industrial DevLink-C1000 controller. As of August 2019, this controller supports a wide range of open data exchange protocols, which makes it easy to integrate ShSD into almost any information and control system of the customer.

Appointment

• Collection of operational and archival data from metering devices of all types of energy resources
• Data collection from "physical" discrete and analog sensors (optional)
• Control of actuators (option)
• Intermediate algorithmic processing of collected data
• Transfer of data to the upper level to information and control systems using open data exchange protocols OPC (DA, HDA), MEK-104, ModBus RTU/TCP, including SCADA KRUG-2000 via specialized communication channels
• Recording and Intermediate Storage of Collected Data
• Provide the collected information to the operating personnel "on site" using the control panel.

Functions

• Automated polling of metering devices connected to ShSD via wired digital communication channels (RS232, RS485) and "physical" sensors, storage of received data, including archival ones
• Generation of own archives (trends) by assigning a time stamp to operational data (DA) received from the metering device and storing this data in the controller memory
• Remote configuration of metering devices using the standard configuration program from the manufacturer by providing direct access to it (driver-gateway)
• Technical metering of heat and gas directly on the controller (modules "Heat metering," "Gas metering")
• Remote restriction of the power source supply, if this functionality is supported by the metering device
• Indication of data collected from meters and "physical" sensors "in place" using the control panel installed directly in the cabinet
• Transfer of operational and archival data to the upper layer via both wired (Ethernet) and wireless (GSM ) communication channels, including with the possibility of 100% "hot" redundancy of communication channels
• Transfer to the upper level and control panel for indication "in situ" of process alarm on quantitative and qualitative parameters of power resources and alarm of cabinet equipment status (self-diagnostics)
• High-precision time synchronization of both the ShSD controller and the metering devices connected to it (if their exchange protocol allows this). Accurate time signals can be received by the controller both from any NTP available in the network, servers and from Global Navigation Satellite Systems (GNSS) GPS or (GLONASS optionally, a special antenna must be connected).

Components

The data collection cabinet consists of the following main components:

• 1. The DevLink-C1000 controller is a universal freely programmable industrial controller, which is the main element of the cabinet and provides almost all of the above functionality.
• 2. Power supply units ~ 220V/= 24V for controller, sensor circuits and metering device interfaces
• 3. Control panel for indication of collected data "in place."

Features

• Easy installation and deployment of metering systems based on data collection cabinets (metering cabinets)
• Possibility of easy integration of ShSD into automated information and control systems operated by the Customer
• Intuitive interface for setting up, configuring and programming an industrial controller DevLink-C1000
• A wide range of functionality that can be performed by ShSD - from simple data collection to automated control.

Submission of ShSD for energy resources accounting

On July 23, 2019, the company NPF Krug presented data collection cabinets (ShSD) from enterprise devices account industrial , developed using advanced technical solutions for organizing technical and commercial systems account of all types of energy resources: electricity, thermal energy, gases.

As you know, the presence of an energy metering system is an indispensable condition for the full functioning of a modern enterprise, regardless of its industry affiliation. Creating a metering system from scratch is not an easy and costly task, especially when it is necessary to collect data from a large number of heterogeneous metering devices operating on different exchange protocols. The line of high factory-ready data collection cabinets makes it possible to implement the possibility of budget construction of energy metering systems, as well as fast and easy integration of ShSD into existing automated systems.

The versatility of the use of ShSD (metering cabinets) is provided by a large set of supported exchange protocols with devices from such manufacturers as: Energomera, Incotex, Saransk Instrument-Making Plant, Nizhny Novgorod Plant named after M.V. Frunze, "" Take-off, "" Teplokom, "" Logic "and others.

Depending on the modification, ShSD provides a wide range of functionality - from simple data collection to automated control:

• collection, processing, storage, display of operational and archival data from metering devices, "physical" discrete and analog sensors
• data transfer to the upper level to information and control systems via both wired (Ethernet) and wireless (GSM ) communication channels with the possibility of 100% "hot" redundancy of communication channels
• possibility of technical metering of heat and gas directly on the controller (modules "Heat metering," "Gas metering")
• indication of data collected from metering devices on the touch panel installed directly in the cabinet (option)
• remote limitation of power supply, if this functionality is supported by a metering device
• control of actuators (optional).

The basic element of the ShSD is the industrial DevLink-C1000 controller, which supports a wide range of open communication protocols, which makes it easy to integrate the ShSD into almost any information and control system.
