Definitions

• the invention relates to a data system for monitoring and / or controlling processes, with a processor system, with at least one mobile data carrier and with at least one interface acting as a link between the processor system and the at least one data carrier.
• Such data systems are widely used today, for example for access control, person registration, time registration, billing and for the control and / or monitoring of various processes in many fields of technology, in particular also processes in the context of the industrial manufacture of textile products.
• Keys, magnetic cards or so-called chip cards are used as data carriers, their range of application ranging from simple access authorization for a key to data exchange between data carriers and processor system for chip cards.
• the data carrier must be extremely robust and immune to interference from dust, dirt, moisture, temperature fluctuations, and the usual cleaning agents and solvents. In addition, it should be easy to handle and have a handy size. It is obvious that these requirements would best be met by a simple key, which, however, has the disadvantage that no data exchange with the processor system is possible. On the other hand, if magnetic cards or chip cards are used, then data exchange is possible, but only if an increased susceptibility to the mentioned disturbances is accepted.
• the aim of the invention is to create a data system whose data carrier enables data exchange on the one hand, as far as possible with the preferred possibility of programming the data carrier, and on the other hand also under difficult environmental conditions, such as, for example are given in a production plant, can be used reliably and reliably.
• this object is achieved in that: a) the data carrier is designed like a plug and has a housing and a circuit arranged in it; b) the interface is designed to insert the data carrier and has appropriate means for data exchange between the data carrier and the processor system; and c) the data carrier is supplied with operating energy via an interface, both the energy supply of the data carrier and the data exchange mentioned being carried out without contact.
• contactless means, for example, inductive, so that all electrical contact surfaces or points can be dispensed with. whereby the reliability and robustness of the data carrier is suddenly increased and the mentioned interference influences are eliminated.
• Another advantage is the energy supply via the interface, which means that there is no need for a battery in the data carrier.
• the data carrier is designed in the form of a flat prismatic body, the area of which approximately corresponds to that of a conventional credit card, the circuit being embedded in the housing and enclosed on all sides by the latter.
• a further preferred development is characterized in that the housing of the data carrier is graduated and that the interface is provided with a slot, the cross section of which is adapted to that of the graduated housing part with the smaller thickness.
• the data carrier is thus a prismatic body closed on all sides, in the form of a thin box or a credit card a few millimeters thick, which, because of the gradation of its housing, can only be pushed into the interface with one of its end faces.
• the data carrier is absolutely insensitive to environmental influences such as dust, moisture, temperature fluctuations and cleaning agents or solvents and its robustness can certainly be compared to a key.
• the system according to the invention can not only be used for monitoring and / or controlling processes in production plants, but can also be used in many other areas. Such areas are for example:
• FIG. 1 is a schematic perspective view of a data carrier according to the invention and an associated interface
• FIG. 3 shows a schematic perspective illustration of an arrangement for process control / process monitoring in a production plant.
• a mobile data carrier 1 shows the two main components of a data system according to the invention, namely a mobile data carrier 1 and the associated interface 2, which is the link between the data carrier 1 and a not shown posed processor system forms.
• the latter is symbolized by a plate 3 which supports the interface 2 and which, for example, forms the housing front plate of a control unit of the processor system.
• the data carrier 1 has a flat shape with the approximate dimensions 64 x 45 x 9 mm and has a two-part housing, an electronic circuit being inserted in one housing part 1 'and the other part 1 "being designed as a cover.
• the two Housing parts l 1 and l 1 ' are connected to one another in a suitable form along their separating edge 4. They are preferably welded with ultrasound, and plastic is used as the housing material.
• the data carrier 1 is graduated, the thinner part being provided for insertion into the interface 2. Accordingly, the latter contains a slot 5 for receiving the data carrier 1, the slot width being adapted to the thickness of the thinner part of the data carrier 1. Its thicker part serves as a grip part when inserted into and pulled out of the interface 2 and has a surface that is easy to grip. This surface is preferably roughened, corrugated or ribbed.
• the data carrier 1 has on its grip part a bore B for a fastening means, such as a chain or a cord.
• the housing part 1 contains a printed circuit board 6 with the required electronic circuit.
• the printed circuit board 6 is by means of a bolt 7 projecting upwards from the bottom of the housing part 1 ' Centered housing.
• a web 8 with a cross-shaped cross section for attaching a coil S1 or S2, and a web 9 for securing these coils against rotation
• an L-shaped web 10 for holding and centering the printed circuit board 6, and a web 11 for holding a strip-shaped iron plate 12, which is clamped between these webs and the end wall of the data carrier 1.
• housing part T All parts contained in the housing part T, that is to say the printed circuit board 6, the two coils S1 and S2 and the iron plate 12, are cast into the housing part 1 'with a synthetic resin. This not only means that they are fixed and secured against slipping, but also results in a not inconsiderable protection against impact.
• the circuit board 6 includes the necessary electronic components, da ⁇ down in particular a memory part having a plurality of memories, which run in EEPROM technology, and are therefore "non-volatile., Chem the formed depending on the memory size of one or more integrated circuits in these Spei ⁇ Among other things, the parameters of the data carrier 1 are stored, some of which serve for its internal organization (definition of the various possible access rights to the data).
• the memories also contain write and / or read-protected registers for the system manufacturer or for the system user and free registers for the inclusion of further data.
• the data exchange takes place via the two coils S1 and S2, which are inserted with opposite polarity through 180 ° in the housing part 1 ', and one of which serves as a data channel and the other as a control channel.
• the coils S1 and S2 also serve to supply energy to the electronics, so that the data carrier 1 does not require any batteries.
• the interface 2 (FIG. 1) contains, in the area of the receiving slot 5 for the data carrier 1, two identical coils aligned with the coils S1 and S2, which are controlled in such a way that which of the coils S1 and S2 is irrelevant for the data exchange with which coil of interface 2 is connected. It is therefore not necessary to pay attention to the rotational position in which the data carrier 1 is inserted into the interface.
• the coils of the interface 2 are controlled with pulse packets of different frequency and phase position and, when the data carrier 1 is inserted, it is transmitted continuously via a channel, so that energy transmission takes place continuously.
• the control takes place via an IC arranged on the interface 2, from the output of which is symbolized by a connector 13, a cable is led to a suitable interface.
• each of the two coils 1, 2 can optionally send one of two signals of different frequencies, for example one with 113.8 kHz and one with 455 kHz.
• the signal with the frequency of 113.8 kHz is used for energy supply; If transmission is not carried out at this frequency, the energy supply is bridged by means arranged in data carrier 1, such as capacitors.
• the frequencies mentioned represent the different signal types, the phase position represents the content of the data information.
• clock pulses clock pulses
• data information data information
• CS Chip Select pulses
• the clock pulses and the CS pulses are defined in that both coils 1 and 2 switch between the two frequencies mentioned in a specific sequence. Data is available when there is a signal of the same frequency on both channels. If there is no phase difference between the two signals, this corresponds to the content "0", if the phase difference is 180 °, then this corresponds to the content "1".
• the interface 2 also contains a magnet in the base of the slot 5, which holds the latter in the slot 5 as a result of the force exerted on the iron plate 12 in the data carrier 1, as a result of which the disk 1 is secure in the interface 2 even when the interface 2 is inclined forward is held.
• the interface 2 also has two signal lamps 14 on its front, preferably light-emitting diodes, which are arranged in different whose colors light up and display the two operating states “data carrier detected" and "data exchange is taking place”. Of course, in the latter operating state, the data carrier 1 must not be pulled out of the interface 2.
• the reference numeral 15 denotes a clamping element in FIG. 1, by means of the clamping action of which the interface 2 is held in the front plate 3.
• FIG. 3 shows an arrangement used in practice for process control / process monitoring in a production plant.
• the figure shows a section of a data system for a textile company;
