The new PostgreSQL database is developed for systematization and unification of the data archiving and observation at the VEPP-4 facility. About three thousands parameters are set and checked for the VEPP-4 control. The current values are read from the control and measuring electronics and stored into the many files with different time of storing. The storing intervals vary from one second for the pulse systems to several minutes for the slowly changing parameters. Parameters are transfer to the database as soon as they are renewed in the source files. Twelve independent processes running under Linux provide the permanent data transfer from the files with current values to the database. The graphical interface is developed for user’s access to the database. It provides observation of the stored data in graphical or textual form and monitoring of the current parameter values. The interface allows us to observe any collection of parameters in a single or in different windows for any period of time.

The temperature conditions affect the circulating bunches parameters in colliders. So, the permanent temperature measurements are very important for the estimation of the beam energy during the experiments with colliding beams. The system is realized in order to measure precisely temperature in a lot of points (about 500) of the VEPP-4M facility: magnet yokes, coils, air in the tunnel and electrical power connections, RF cavities, water cooling, environment. The system provides the interlock functions. In the case of overheating in measuring points the system switch off the corresponding power supplies. The system is based on using of DS1631Z Accuracy Digital Thermometers and 32-channel home-developed controller. The controllers are connected to PC via serial interface. Temperature values are renewed automatically for the all channels in each controller in 0.75 second. The program running in PC reads the data from the all controllers and transfers the temperature data to PostgreSQL database every minute. The graphic interface provides browsing of the temperature diagrams for the selected thermometers for any period of time. All the programs run under Linux.

Implementing Graphical User Interfaces (GUIs) for complex control systems (CS) implies many development challenges, especially for prototyping and refining. We propose to improve current practices by introducing a model-based, domain specific approach to GUI development. Our methodology* is founded on the assumption that most information to be used for GUI prototyping can be derived by the CS specification itself. We use model transformation techniques for automatic generation of a GUI from a domain specific model. We apply the methodology to the CERN CMS Tracker Cosmic Rack as a case study.
