Other functions include system sizing and preventative maintenance information. Allows operators to maintain appropriate tank levels, monitor flows, and pressures, and detect leaks throughout the system.
SCADA systems collect real-time metrics and provide remote control functionality to the proper authorities. High Tide Technologies is an end-to-end cloud-based SCADA company that enables our users to create a complete SCADA solution that utilizes field units, satellite, cellular or Ethernet communications as well as the Internet to monitor and provides automatic control of your systems. What is Telemetry? Repeaters Repeaters receive and retransmit signals.
Collections Systems Alerts technicians and operators of pump and overflow alarms, enabling them to respond to situations with data-informed solutions. Distribution Systems Allows operators to maintain appropriate tank levels, monitor flows, and pressures, and detect leaks throughout the system.
One of the key functions of a SCADA system is alarming, which allows you to select a safe range for a chosen parameter and get notifications if that parameter skews outside your range.
As control systems develop and get smarter, many are able to use the data collected by SCADA systems to adjust its setpoints and processes automatically, keeping your systems running more efficiently. Most importantly, SCADA gives you direct access to the data critical to your systems, ensuring that you make informed decisions about your system. Need help with an old one? Skip to content.

Customer Portal. Jul 24 RTUs and Telemetry Instrumentation is connected to a remote terminal unit RTU which converts the signals from the equipment into a data stream that is communicated to the central location, where a data concentrator collects the data and feeds it to the operator terminal.
Early Years The communications link itself has undergone massive changes through the years in the technology employed. Wireless Over time, hardwire connections became less practical and more expensive.

If also the functions of control are required, generally the similar software transfers commands to the actuators through the RTUs and base station, once the conditions of pre programmed are met, otherwise they may be operator activated, such as manual operation.
There are a lot of solutions of the SCADA software, but regrettably most of them are either too lacking and simplistic in functionality, or over complicated and difficult to control by non-technical users. Generally the software developing is very high costs and low return because of the limited quantity of customers. If the developer gives the right price it could be nobody will buy the software.
The data acquisition starts in the airborne system, when sensors measure the amount of a physical attribute and transform the measurement to an engineering unit value. Some sensors also produce a voltage directly thermocouples for temperature or piezoelectric strain gages for acceleration , while others require excitation resistive strain gages, potentiometers for rotation, etc. Sensors attached to signal conditioners provide power for the sensors to operate or modify signals for compatibility with the next stage of acquisition.
But maintaining a separate path for each source is time consuming and costly. So a multiplexer is used. It serially measures each of the analog voltages and outputs a single stream of pulses, each with a voltage relative to the respective measured channel. The Output Formatter serializes the composite parallel data stream from the multiplexer Mux to a binary string of pulses i. Later this binary signal is transmitted through copper wire or a fibre optic cable.
These days, PCM or pulse code modulation system is used with the data stream, so that the original data can be sent more accurately, with minimum loss of data. In the ground system, the received data stream from the transmission line is amplified. Since this transmission path is filled with noise, the original signal may get distorted. So to get the original signal, a bit synchronizer is used which reconstructs the distorted signal to the original serial signal.
Then, a demultiplexer DeMux recognizes the synchronization pattern and returns the serial digital stream to parallel data. SCADA monitor and control entire sites or complexes of systems over large areas on the scale of kilometres or miles. Most controls are performed automatically by remote terminal units "RTUs" or by programmable logic controllers "PLCs".
