LOCAL WEB – software for monitoring systems

admin_tc — Mon, 26 Sep 2022 23:39:53 +0000

LOCAL WEB is a WEB HMI SCADA application for devices, which use Embedded Linux operating system. SCADA (Supervisory Control And Data Acquisition) is software application, what is designed for real time operating to collect, display and archive information related on monitoring and controlling objects. WEB HMI (Human-Machine Interface) is net interface, based on standard markup web languages using to display in web browsers, what allows a user to interact with system control.

Local Web application is developed and supported by TERA since 2017. In development it’s implemented contemporary technologies such as Embeded Linux (Kernel 4.x), NGiNX, NodeJS, AngularJS, WebSocket, Microservice IPC, JSON, SQL Data Base. Local Web is installed on CS10600 Datalogger with Embedded Linux operating system, and it uses only its CPU and memory. There is no needings to instal this application on user’s devices, no third party apps or cloud servers.

Local Web application operates with wired tranducers (Ethernet or RS485 interface) and wireless transducers (WiFi, ZigBee 2,4 GHz and 868 MHz, Bluetooth, etc.). It supports the work with several users simultaneously, that allows to monitor and to control the process using any PC, tablet or smartphone connected to Internet. For data operating the user needs just to follow the link in Chrome browser and input login/password on the server, that’s needed to be put under control.

Local Web offers the flexible system of assignment user’s rights, that’s setting up by an administrator in advance. It allows to devide users on the various of groups with own credentials and roles: an administrator, an operator, a user, etc. Depends on rights, user is allowed to view and change certain data and projects.

The application creates a certain project for specific technological process, data receiving and control. Each certain project keeps its data, configurations, preferences for displaying and controling. Online data received from devices within one project is available to group by common features. By the group it generates charts, reports, tables. Also it allows to determine alarm signalization range.

Local Web allows the user to control devices remotely at real time, to display archived data, to generate charts, tables, reports for certain time period, to export data in PDF file. In the charts it’s available to scale by X and Y axis, to add/remove additional axis, to change color, line appearance, etc. On the detailed chart the user may attach a chosen option or its group. Over main part of detailed chart there is the widget called time line with trend preview. This widget allows the user quickly and intuitively to define necessary time period for generating detailed chart. Besides of chart vizualization, the user may view archived data in the table within certain time period.

Also in Local Web there is implemented the flexible system of preferences for alarm signalization. It allows to set up the range of alarm detecting, as well as to choose the users for alarm notification via messangers. The data and its groups indication change the color online depending on presence device connection, standing at normal, pre-alarm or alarm state. In addition the operator, staying online, views blinking alarm icon at the left-hand part of a screen. It stops blinking after the operator approves it.

The system keeps a technological log and a user’s action log. The technological log keeps all of alarm and errors in the technological devices. Also it keeps user’s action for current alarm: when and who approves it. The action log keeps preferences changes and configurations of Local Web, projects, groups and data, that was acting by a certain user in certain time.

Local Web has possibility to generate mnemonic scheme of the technological process as widgets with active parts. Widget allows to vizualize the real time process of control. These widgets are options, that generates with a customer order for certain technological process.

Cold Chain Cloud – SaaS service for monitoring systems

admin_tc — Mon, 26 Sep 2022 23:12:10 +0000

Cold Chain Cloud is a cloud-based SaaS service that solves two main tasks:

The first is the collection, monitoring, and centralized storage of data from a large number of measuring instruments (loggers, sensors, recorders, etc.). Measuring instruments can interact with Cold Chain Cloud using various data exchange protocols and be located in different geographical regions;
The second is providing authorized user access to measurement data through a web interface and displaying this data in a user-friendly format.

Cold Chain Cloud is a platform-independent service. The user interacts with Cold Chain Cloud through a web browser, without the need to install any additional software on their computer.

The advantage of Cold Chain Cloud lies in its client-server architecture. This architecture allows part of the data processing load to be offloaded from the server to the client’s device, thus improving system performance and reliability.

The server side provides, on one hand, interaction via the server API with measuring instruments (loggers, sensors, recorders, etc.). On the other hand, the server interacts with the client side through a client API, delivering data based on the user’s requests. Therefore, the main functions of the server side are data collection, preliminary processing, storage, backup, and provision of data to the client side.

The server side is software written in JavaScript (Node.js) and C++. It runs under the Linux OS and is hosted on servers in a data center. The client side is a JavaScript (AngularJS) application that automatically loads in the user’s web browser and operates until the browser tab is closed. The client-side service provides interfaces for real-time user interaction with data, such as: graphical visualization of historical data from all devices, viewing charts, archives, logical events, alarms, various widgets, system settings, and more.

Cold Chain Cloud offers a flexible user access control system, preconfigured by the system administrator. Users can be divided into different groups with different privileges and roles: administrators, operators, users, etc. Depending on their permissions, a user can modify or view only the data and devices available to them.

Online data received from various instruments can be grouped by common characteristics. Charts, reports, and tables can be built for these groups, and alarm thresholds can be configured.

Cold Chain Cloud allows users to monitor and control instruments remotely in real-time, view data archives, create charts, tables, and reports for specific time periods, and export data to PDF files. Chart scales on X and Y axes can be adjusted, additional axes can be added or removed, and axes, colors, and line types can be customized. Detailed charts can display either a single selected parameter or a group of parameters. Above the detailed chart area, a “timeline” widget with a preview of chart trends is implemented. This widget allows users to quickly and intuitively select the desired time range for detailed chart building.

Cold Chain Cloud includes a flexible alarm configuration system. Alarm thresholds can be set, and users can be configured to receive notifications via Telegram, any other internet messenger, or email. Depending on device connectivity and data status (normal, pre-alarm, or alarm), the color of data values and groups changes in real time. Additionally, an operator connected in real-time sees a blinking alarm icon at the top of the screen, which stops blinking only after the operator acknowledges (confirms) the alarm.

Cold Chain Cloud provides a technological log, a user activity log, and a system log. The technological log records all alarms and failures in the technological equipment, as well as user responses to alarms — who acknowledged them and when. The user activity log records configuration and settings changes made within Cold Chain Cloud, projects, groups, and data by specific users at specific times.

Cold Chain Cloud also supports creating process flow diagrams (mnemoschemes) in the form of widgets with active elements. These widgets allow visualization of monitoring and control processes in real-time. Widgets are a customizable option developed per customer specifications and approved according to the client’s technical requirements.
