Why Baudisch.ControlSeries?

There are many systems for access control and time recording - ranging from classic cylinder locks or time clocks to sophisticated and complex electronic systems. Depending on the design, but nearly all construction-conventional systems have disadvantages. Complicated operation, error rate and lack of comfort have been the main problems.

Many reasons, therefore, to choose a systems where all requirements are fulfilled. Reliability, ease to use, convenient expandability and easy installation are important characteristics that must be met. Reasons that speak for a solution from the Baudisch.ControlSeries.

There is a simpler way...

Compared with standard procedures for time recording and access control based on PIN numbers, data collection terminals, mechanical keys, chip and magnetic card readers, the used transponder technology from Baudisch offers a number of advantages.

The detection of a transponder is contact-free, which prevents wear on the transponder or reader. No PIN must be memorized, no contacts can contaminate or oxidize, stored information can not be erased by magnetic fields or made unusable.

The procedure

Each transponder is pre-programmed individually with its own key number. A transponder reader generates a weak magnetic field with a few cm range. Now, if a transponder is held in this magnetic field, the internally stored key number in the transponder chip is transmitted to the transponder reader. The transmission from transponder to transponder reader is via air. The reader records this number and reports it together with its own code to a central unit. This central unit collects working hours and decides further over the authorisation of the imported combination of "key" and "lock". Doors are opened or remain closed accordingly.

Depending on which system of the Baudisch.ControlSeries, these messages are also saved and can be evaluated as needed.

The communication

Readers, control and central units communicate over the Fieldbus "EasyLan," a product developed by Baudisch Electronic. Data is transferred in a specially encoded and secure digital process, so that manipulation is not possible.

The connection is made via three wires of a standard 2 communication cabel e.g. n x 2 x 0.6 mm J-Y(ST)Y and can be implemented with distances up to 1,000 meters between the individual components. The devices in the ControlSeries are compatible with each other. Thus, already connected components can continued to be used in a system upgrade.

Appropriate modules are available for the implementation of "EasyLan" to standard Ethernet, RS232 or USB. The integration of PC's or the networking of individual "EasyLan" bus segments is therefore easily possible.

Safety first

To open the door unauthorized by manipulation of the transponder reader is impossible. The code of the transponder is simply identified and forwarded.

The decision of authorisation access which opens the door is made in the central unit, which controls the electric door opener on a separate switch module. This switch module is a programmable two-channel relay unit. Since the central unit and switch module are located in the building, the system is protected against abuse.

Power outage

In such a case, the so-called "fallback level" comes into play. This term is referred to an emergency system, which ensures the implementation of the most important functions in case of main system failure i.e to open a locked door.

The working hours

The same components are used for the recording of working time as for the access control, i.e. transponder chip and transponder reader. For each type of working hour entry ( beginning hours, ending hours and business trip ), a separate transponder reader is installed and configured according to its function. The transponder for the door also serves the recording of the working hours.

The advantages

In case of loss of a conventional key, usually the associated lock or the complete system must be replaced. Apart from the time and effort, mostly it generates significant costs.

Unlike the series of systems of the Baudisch.ControlSeries: the authorisation of the chips can always be deleted without having to replace parts of the system. Also, authorisations of new transponders are entered in no time in case additional chips are needed or to replace lost ones. Deleted chips are rejected as unknown until they are reestablished.
No expensive data collection terminal for the time recording has to be installed in hallways or entrances, which operation must be taught separately usually with considerable effort. Depending on the system, each employee may retrieve his current data at any integrated PC in the system, which takes off a major burden from accounting.
