DAKSwin
Controlling and recording temperatures, pressures, valves and monitoring the boiler house. To assure that the hardeningprocess is able to run smoothly we have the right tool for you:DAKSwin software is a compact, computer aided control system.It lets you manage max. 120 valves, 80 sensors (4-20mA) and approx. 80 inputs and outputs (for the operation of brick hardening boilers), this means that about 20 boilers, as well as the boiler house, can be monitored and controlled at the same time.
damko has been operating its own software department since 1989, which continually updates our DAKSwin control program. The size of your plant is irrelevant for DAKSwin. Even if you expand your system, DAKSwin simply grows along with it without any complication.
Advantages:
- simple maintenance
- automatic valve calibration
- programmable weekend mode
- enables a mix of automatic and manual
- operational sequences
- safety system “Watchdog”
- pressure-time-product control

The hardware consists of a central cabinet including a PC computer, monitor and printer and a local sub-unit per thermo-technical plant component.
The sub-units are switch cabinets impermeable to splash-water, each time equipped with the same type of electronic measuring equipment and control electronics for connecting pressure and temperature sensors, door contacts and up to 5 engine valves with position and end position and detectors.
Each of them is mounted in the immediate vicinity of a plant component. This provides for short wiring distances to the valve gears and sensors. In terms of electrical installation, this means a minimum of expenditure and a maximum of clear arrangement. Starting from the central cabinet, only 2-wire data cables and a power line interconnect all sub-units.
When commissioning or later on extending the installation, all the functions of an individual plant component can be verified systematically first. After inserting the data cable into the sub-unit, the respective plant component becomes available to the complete system immediately.
The electronic measuring equipment will collect performance data like pressures, temperatures and valve positions at different plant components and will transfer these in the form of digital signals through the data line to the PC computer.

The developed DAKS software will generate, from many hundreds of single items of information, converging in the PC computer, a virtual image of the installation. The data obtained will be logged in a user-friendly way on a continuous basis and will form the basis for controlling the steam flows using the electrically operated valves. When developing DAKS, essential control functions used for detecting technical defects of sensors at an early stage or valves as well as erroneous process cycles have been integrated. A watchdog timing of the programme in conjunction with an integrated diagnostic system for temperature and operational voltage monitoring of the sub-units ensures a high availability of the system at anytime.
|
The sub-units collect the measured data and control the valves. They are mounted near the installation. This reduces the cable runs for sensors and valve gears, and the installations costs stay low. The wiring is the same for each unit, which increases the clear arrangement and maintainability significantly. The controlling computer processes these information using the DAKS programme, controls, checks and protocols the process and constantly checks the operational readiness and functional efficiency of all sensors and actuators.

The adaptability of the segment plate valves is very multifunctional due to the small dimensions. The valve is supplied in a connection flange design by default, but can also be supplied with aligned adapter flanges on customer request to allow a direct exchange with existing hand valves. The image shows a steam distributor of a KS-hardening machine equipped subsequently with segment plate valves and control.

Always at your service
The parameter configuration of the overall system is made exclusively at the central cabinet and can, if required, be changed anytime by the plant operator. In the sub-units, there is a firmly installed operating system, but no software to maintain and no mechanical adjusting elements. The DAKS software makes a multitude of functions with arbitrary parameters available. These include an energy and time-optimised behaviour when dealing with excessive steam, pressure-time-products monitoring and a steam quantity measurement during the process and, of course, the exact compliance with a desired and given pressure progression. All settings of the programme can be performed without any interruption during the actual operation and will become effective immediately.

The long lasting experience in the field of development, construction and commissioning of controls will be included continuously in the DASK software to the user’s advantage in the future also. Each DAKS programme is customised to the specific requirements of the customer installation. Any later programme changes or additions are programmed outside of the installation and tested in a simulation installation so that the installation, which can be executed by the user himself within a few minutes, will run smoothly and can provide the desired results immediately.
Very communicative
Using additional interfaces on the PC computer, the DAKS programme can exchange “data packets” with other machines or installations. For example, the optimum hardening programme for a tank travel can be determined automatically from the data of a traverser control, or certain operating states of the hard tank control are conveyed to a central visualisation.
User-friendly
The graphic user interface of the DAKS programme is operated exclusively with a "mouse” as input device. The arrangement of the operating elements on the computer monitor, which can be “clicked” with the mouse pointer, is always adapted to the current situation so that even setting complex parameters using "one-button operation” does not cause any problems.
So the graphic setting of the up to 64 pressure-time-specifications programmes is as easy to handle as setting the process parameters for which context-related help texts are additionally available anytime.
This user-friendly concept reduces faulty operation to an absolute minimum, guides the user of the installation intuitively during work and so promotes the acceptance of the computer as working instrument with the operating staff.
One for all
The DAKS system shall be understood as a manager of the steam and condensate balance for the entire thermotechnical equipment. It does not only control the heating up and keeping of the parameters, but also the distribution of old steam to other consumers. Moreover, also the de-aerator, pre-heater and an energy store can be included in the control.
The energy store has been mounted for the first time in 1997 at a GS plant. The operator confirmed to us oil savings of 8% from the day of commissioning. Today, we offer a low-and high-pressure combination to make efficiency even higher.
Activating the de-aerator by means of DAKS assures an optimum operating temperature while exploiting old steam at maximum level.
The central control of the pressure reducing station and heat recovery makes it possible to save even more energy.
