A plan view of the data carrier mentioned above, III perspective view of the arrangement of the It is.

Figure 81 shows the main structure of the data system according to the present invention, as well as the processes that are not included. It forms a wag child with the system. This processor system It is supported by a plate 3 which holds a Forms the front panel of the housing of the system control device.

Data carrier 1 has a flat shape with a circuit dimensions of 64 x 45 x 9 mm. It has a strong and two-part housing, - a howling part 1 ' has an electronic circuit inserted in it, and the other part 1'' is configured as a 6-car The other housing parts 1' and 1'' are joined together in a suitable manner along the separating edge 4. The housing material is made of plastic, preferably ultrasonically welded. plastic is used.

Data carrier 1 is structured in stages, with the thinner one being the interface The base includes a slit 5'2 for accommodating the data carrier l; The tin of the tin is matched to the thickness of the thin tenth part of the data carrier 1. this day The thicker part of the carrier is inserted into and out of interface 2. It is used as a grip when withdrawing from the base, and has an easy-to-grip surface. . This surface is preferably roughened, corrugated or ribbed. Preferably, the data carrier 1 is provided in a fixed position, e.g. The mounting has a hole B for means such as a card.

As can be seen in Figure 2, the housing part 1' is a printed circuit board with the necessary electronic circuitry. It includes a top plate 6. The printed circuit board 6 projects upwardly from the bottom of the housing part 1'. It is fitted into the housing by a pin 7 which is attached to the housing. Data carrier! Place the W number on both front corners of the thin part of the pieces are placed. In other words, a cross-shaped cross section for fitting the filler Sl or s2. A holding protrusion 8, a protrusion 9 for preventing rotation of these fills, and a protrusion 9 for holding the printed board 6. To hold the L-shaped protrusion 10 and the strip-shaped iron plate 12 for holding and centering. One projecting piece 11 is arranged on each side, and this iron plate is connected to these projecting pieces and data. It is tightened between the end wall of the carrier l.

All parts included in the housing part 15 yen, i.e. printed board 6, both sides The sword fills SL and s2 and the iron plate 12 are made of plastic and the housing part is 1' circle. is formed. This not only means that they are fixed and non-slip; , it also provides considerable protection against impact effects.

The printed circuit board 6 contains the necessary electronic components, in particular a storage section with multiple storage devices. These storage devices are constructed with EEPRO)I technology and are therefore non-volatile. It is idiopathic. These are formed from one or more integrated circuits depending on the amount of storage. In particular, the parameters of the data carrier I are stored in the storage device of the Some of the parameters of this data carrier are Storage devices are also used by system manufacturers to A secure register for writing and/or reading, preferably for system users. data and a confession register for v5#a other data.

Data exchange takes place via both coils Sl and S2, which are These coils are fitted into the housing part 1' with a 180° polarity change. One of the channels is used as a data channel and the other is used as an am channel. used. Coils Sl and S2 are further used for energy supply to electronic devices. data carrier 1 does not require an S pond.

Interface 2 (Figure m1) is within the range of accommodation slit 5 of data carrier January, It includes two similar coils forming two M wires with coils Sl and S2, and these Which of the fills Sl and S2 is connected to which coil of interface 2? Energized so that connectivity is not important for data exchange. Therefore , in which rotational position the data carrier 1 is inserted into the interface. No need to be careful, the coil at interface 2 is connected to pulses with increasing frequency and phase. energized by a packet and permanently channels when a data carrier is plugged in. Since the transmission takes place via the channel, energy transfer always takes place.

Activation is performed via an IC located at interface 2, and the plug of this IC From the output end indicated by the plug 13, the cable is led to the appropriate connection point.

The coil 51 and S2 of 11IN'j5 provide two transmission lines, or in other words, a channel. channel. Depending on the insertion direction, one of coils l and 2 Used for transmitting or receiving information on a channel, the other coil is connected to the other channel. Evaluation of the frequency and phase of the signal in both channels helps in Transmit more than one signal on these two channels without having to do any encoding can do.

Each of the double-edged coils 192 selectively receives one of two signals at a frequency. For example, transmitting a signal with 13.8 kHz and a signal with 455 kHz. be able to. In this case, the signal with a frequency of 113.8kHz is the energy supply used for. If not transmitted at this frequency, e.g. a capacitor The energy supply takes place by means arranged on the data carrier l.

The frequencies mentioned above represent the various signal forms, and the phase represents the content of the data information.

Three signal types are provided. Clock pulses, data information and so-called C5 (=Cbip 5elect) pulses, and these are the data exchange specified. This guarantees that this can only be done via a specific signal. Clock pulse and CS The pulses are applied to both coils] and 2 toggle the image frequency mentioned above in a specific order. 8 If both channels have a signal with the same frequency, If there is a phase difference between both signals, this means that the data information is present. If the phase difference is 180°, this corresponds to 1@ to Pg and rIJ.

The interface 2 further includes an a-stone at the bottom of the slit 5, and this magnet This data carrier is moved through the slit 5 by force acting on the iron plate 12 in the data carrier 1. , so that the data carrier 1 is held diagonally forward so that the interface 2 is This interface ensures that the pin is held securely even when assembled.

Finally, the interface 2 has two further signal lamps 14 on the front, preferably light emitting lights. diodes, these signal lamps glow in a variety of colors and both work Status lit: Displays “data carrier recognized” and “data exchange performed”. Ru. In the latter operating state the data carrier 1 is pulled out from the interface 2. Of course, this should not be the case. In Figure 1, reference numeral 15 indicates the tightening mechanism. The tightening of this tightening mechanism 1 is due to the action of the interface 2 on the front plate. It is held at 3.
