Definitions
- the present invention relates to a
- Data transmission device for the control or regulation of an operating process, in particular a data transmission system for the expansion control of a mining operation in underground mining.
- serial fieldbuses are mainly used as a communication system for the exchange of information between automation systems and with connected decentralized field devices.
- Profibus is the leading open fieldbus system in Europe that is used successfully worldwide. The area of application includes process, manufacturing and building automation. Profibus has been standardized in the fieldbus standard EN 50170 as an international, open fieldbus standard.
- Profibus defines the functional and technical characteristics of a serial fieldbus system and differentiates between master and slave devices. Master devices determine the data traffic on the bus. If a master has bus access authorization, it may do so without an external request
- the Profibus protocol describes the master as an active participant on the bus. Slave devices are passive participants on the bus. You do not receive bus access authorization, i.e. they only acknowledge received messages or only transmit messages to the master upon request.
- the bus access authorization is regulated by a uniform bus access protocol and the bus access control.
- the bus access protocol contains the functions of data backup and the processing of telegrams and transmission protocols.
- the bus access control is used to determine the point in time at which a bus subscriber receives data may send. In addition, the bus access control ensures that only one participant has transmission authorization at a time.
- the Profibus protocol contains two essential requirements for bus access control:
- the Profibus bus access process therefore implements the token passing process for the communication of complex bus users (masters) with each other and subordinates the master-slave process for the communication of the complex bus users with the low-cost peripheral devices (slaves).
- the token passing procedure guarantees the allocation of the bus access authorization (token) within a precisely defined time frame. To hand over the token
- the master has the option of picking up messages from the slaves or forwarding messages to the slaves.
- a token ring is used to denote the organizational sequence of active nodes that form a logical ring through their bus addresses.
- the token bus access authorization
- Participant of the token telegram he exercises the master function over the bus for a certain time and can communicate with all slave participants in a master-slave relationship and with all master participants in a master-master relationship.
- Profibus can manage a maximum of 128 active participants (masters) on the bus.
- a master-slave system was chosen for a longwall with more than 200 electro-hydraulic shields in order to ensure full compatibility with the standard.
- the Strebbus master and slave alternate, whereby the slaves do not actively participate in bus events.
- the master-slave configuration is also defined. If the predecessor was a master, the subsequent control unit goes into the slave state and vice versa. It is important that all control units are identical in terms of their hardware configuration.
- an expansion control concept as described above requires an identical control unit in terms of hardware for each expansion, since the master-slave configuration is determined by the addressing of the control units and can change at any time because the extraction operation is variable in the number of required over a certain length of dismantling Shields must be in the face. If the number of shields in extraction operation changes, the configuration of the control units also changes, ie a control unit that was previously active as a master can then have to perform the task of a slave and vice versa.
- the disadvantage here is that half of the control units are completely oversized in terms of hardware in order to perform the tasks as a passive participant on the bus (slave function).
- a data transmission system of the aforementioned type is known from DE 295 14 236 U1.
- master and slave devices are alternately provided as control devices along a face bus designed as a Profibus.
- Embodiment it is also known from this utility model to design only every third control device as a master device, this master device then coordinating the two following devices. In this way it is even possible to control more than 256 control units via a single Profibus. However, this is done according to the extremely disadvantageous master-slave method.
- the problem on which the present invention is based is the creation of a data transmission of the aforementioned type which comprises more than 128 control units actively involved in the data transmission and in particular nevertheless realizes the expansion control with little effort.
- the basic idea of the invention provides that the communication between the control units is carried out by means of a pure master-master system by using a plurality of face buses.
- the advantage of the invention is that all control units are registered as active participants (masters) on the Profibus and the data volume on the bus is reduced by approx. 50% and thus considerably shorter bus access times can be realized and thus also safety-relevant Data information can be exchanged more quickly.
- the usual master-slave procedure is no longer necessary and the control units implement communication with each other according to their existing hardware.
- the neighboring bus is relieved of the usual telegrams running via the face bus and only fulfills the following functions:
- this device connection can be carried out without a complex Profibus basis and the associated hardware and software.
- the functions of the neighboring bus are implemented by two UART interfaces from the control processor with the corresponding conversion to the RS 485 interface and electrical isolation.
- Figure 1 shows the arrangement of power supply, buttress centers, control units, bus terminals, two buttress buses and neighboring bus in a schematic representation.
- Fig. 2 shows the objects of Fig. 1 using three
- FIG. 3 shows the objects of FIG. 1 in a further embodiment
- FIG. 4 shows a more detailed schematic illustration of the connections between the face buses and the control devices according to FIG. 1.
- a control unit 5 with an integrated module 6 is assigned to the expansion units (not shown).
- Control unit 5 is designed in an intrinsically safe housing according to EN 50020.
- the integrated module 6 is supplied with energy either via a housing 2 or a housing 3, which are designed as housings with a weatherproof or specially protected encapsulation.
- a lamp 19 is housed, which with an energy saving lamp
- Power supply of 230 volts is designed. Furthermore, there is a power supply unit 13 in the housing 2, in which the lamp voltage is transformed to 12 volts in order to supply several integrated components 6 with energy.
- a power supply unit 13 is also provided, in which the applied voltage is transformed from 230 volts to 12 volts .
- the lights 19 and power supplies 13 present in the individual lamp housings 2 and network housings 3 are each connected to one another via a 230 volt power supply cable.
- the integrated modules 6 are each connected to one another via a central 8-, 10- or 12-pole data transmission line 18, in which a first longwall bus 9, a second longwall bus 10, a neighboring bus 8 and the power supply 12 are integrated.
- the longwall center 1 is connected via a 4-pole line 17, into which the first longwall bus 9 and the second longwall bus 10 are integrated, via two bus terminals 4, which are necessary for coupling to the longwall center 1 and are usually installed in the first configuration Integrated block ⁇ of the one labeled STG 1
- Control unit 5 connected.
- the communication between the face buses 9, 10 is in the face center 1 via the interface 14 for the second face bus 10 and via the Interface 15 realized for the first longwall bus 9 by means of the integrated module 7 present there.
- 1 shows eight control units 5, which are designated STG1, STG2, STG3, STG4, STG5, STG6, STG199 and STG200, STG199 and STG200 being intended to indicate that 200 control units 5 are used, for example.
- the 4-pole line 17 starting from the longwall center 1 connects the control center 1 to the two bus terminals 4.
- the first longwall bus 9 and the second longwall bus 10 originate from the two bus terminals 4, each of which is designed with two poles with the two poles 9a and 9b or 10a and 10b.
- the first control device 5 which is designated in FIG. 4 with STG1
- the two poles 9a, 9b of the first longwall bus 1 are tapped and connected to the integrated module 6 via a galvanic isolating unit 20.
- the control units 5 are connected to one another via the cable 18, which in addition to the face buses 9, 10 includes the neighboring bus 8 and the power supply 12.
- the neighboring bus 8 and the power supply 12 are only partially indicated schematically.
- control units 5 Either in each of the control units 5 or in a connection unit assigned to the control units 5 or in the
- FIG. 2 shows that the integrated modules 6 each have a Central 10 or 12-pole data transmission line 18, in which the first longwall bus 9, the second longwall bus 10, a third longwall bus 11, the neighboring bus 8 and the power supply 12 are integrated, are connected to one another.
- the longwall center 1 is connected via a ⁇ -pole line 17, into which the first longwall bus 9, the second longwall bus 10 and the third longwall bus 11 are integrated, via three bus terminals 4, which are necessary for coupling to the longwall center 1 and generally in the first expansion are mounted, connected to the integrated module 6 of the control unit 5 labeled STG1.
- FIG 3 shows a further form of the invention, in which more than three face buses 9, 10, 11 are used.
- the integrated modules 6 are connected to one another via a central multi-pole data transmission line 18.
- the number of wires of the data transmission line 18 depends on the number of face buses 9, 10, 11 used, the power supply and neighboring bus having to be added.
- the multi-pole connecting line from the buttress central 1 to the integrated module 6 of the first control unit 5, designated STG 1, the number of bus terminals 4 and the number of interfaces 14, 15 which the integrated module 7 of the buttress central 1 manages depends on the number of face buses 9, 10, 11.
