Definitions
- the invention relates to a device for transmitting control signals according to the Preamble of claim 1.
- Such devices form the interface between a bus line and above valves to be controlled and, in so far, set serial signals via the bus system are converted into binary signals that can be used by the valve as control signals are.
- two basic principles are known in the prior art.
- a decentralized principle - such as - avoids the high wiring effort it is known for example from the publication DE 39 15 456 - achieved.
- This solution for the transmission of control signals to the valve has the advantage that the bus line is looped through from valve to valve can be and so far a wiring effort for the valves is kept very low.
- connection elements are used Application from the brochure "The intelligent solution directly at the valve” (12/95, Druckblattnr. 885 890 220 3) from Mannesmann Rexroth Pneumatik GmbH are and are also referred to as contact bridges.
- the connecting elements are in essentially of an elongated cuboid housing with at least one connection for the solenoid of a valve, an optical operating status indicator and on Electrical contact means arranged in the housing for connection on the input and output sides with further connection elements. They have the task of decoding electronics and one Driver electronics for converting the control signal into a switching signal for the Electromagnet, which serves as an actuator for the valve, and the bus line loop through to the next connection element. For this they have an internal wiring which is geared towards serial data transmission in the bus system. Inevitable at This decentralized principle requires a lot of electronic components because each valve must be provided with a decoding chip.
- DE 44 44 024 A1 discloses a device for transmitting control signals, between a bus line and a valve unit consisting of several valves is arranged, with connection elements each assigned to at least one valve and with this are electrically connected.
- connection elements each assigned to at least one valve and with this are electrically connected.
- active connection elements there are active connection elements and on the other hand, passive connection elements are provided, of which the active connection elements have a decoding chip that is electrically connected on the input side to the bus line and has more than one connection for controlling valves on the output side.
- the connection elements are star-like connected with each other.
- EP 0 452 658 A1 discloses a type of series connection of electrical connection elements in a row via corresponding input and output side Contacts to create a signal transmission system for the home automation system. It if a bus line is not looped through from connection element to connection element, which transmits serial signals.
- the serial bus line ends at the bus coupling unit (BA).
- BA bus coupling unit
- AU1 ... 4 there is only a parallel one Signal transmission to every consumer (e.g. a lamp).
- this internal parallel looping through the bus line is the number of cascadable Connection elements (adapter units) limited to the number of outputs on Decoding chip.
- the invention has for its object a device for transmitting To create control signals between the bus line and valves with a minimal Wiring effort, and with which a practically infinite number of Connection elements for valves, without exposed outer lines, one behind the other can be connected.
- the invention includes the technical teaching that the active and passive Have connection elements on the input and output side contacts, via which the Connection elements connected in series and by means of internal cables are electrically connected, an extension of which is looped through to the pin Valves can be connected to the bus line in such a way that the output contacts of the last passive connection element with the input contacts of another Active connection element are connected to the further passive connection elements can be connected.
- the active connection elements have decoding electronics in the form a decoding chip.
- the decoding chip is connected on the input side to the bus line and has connections on the output side for controlling valves. At least one connection is guided to the associated valve via the active connection element.
- the others Connections are made via the passive connection elements with the corresponding ones Valves electrically connected.
- This integration of the bus electronics into an active one Connection element has the advantage that a central decoding electronics on the Valve unit can be dispensed with entirely.
- This also enables inventive, partially decentralized principle of the arrangement of the decoding electronics economical use of only one decoding chip for several valves.
- the use of Connection elements instead of an exposed wiring for forwarding the Control signal to the valves also avoids any manual wiring and allows a modular design.
- passive Connection elements used, which are preferably each assigned to a valve. All passive connection elements have an offset internal wiring, so that the Control signal for the valves through the passive connection elements to each to be controlled valve can be passed, the individual passive Connection elements have the same internal wiring and therefore also among themselves are interchangeable.
- the invention provides that in addition to the control lines leading to the individual valves, the Bus line is looped through from pin to pin in the same way. Because of The scarce number of available contacts is particularly suitable for this only two-pole bus system.
- By carrying the bus line through everyone Connection elements it is possible, after the last one in a row passive connection elements which can be connected in series are again an active connection element intrusion, which in turn repeats at least one valve and itself subsequent passive connection elements further valves can be controlled.
- the number of passive connection elements that can connect behind an active connection element is limited by the number of decoder chips on the active connection element Available connections for the operation of valves.
- an emergency stop line supplies the valves to be controlled with the operating voltage. She is Part of a safety-related facility. If the emergency stop line is operated by one central switch off, this causes the actuators to stop immediately the entire system that is operated via the valves without the current Switching state of the control electronics is lost. This is a safe restart the system possible.
- the first valve 7 via the associated connection element 3 and connected to a two-pole bus line via a junction box 2.
- a bus system for the preferred embodiment of the invention is an AS-Interface bus, because this bus standard especially for the control of machine-related binary elements - such as relays, Switches or valves - has been designed and is therefore suitable for use as a fieldbus in the area near the valve is particularly suitable.
- the AS-Interface bus standard only allows serial data transmission via one two-pole bus line, which enables economical cabling.
- the active connection element as a decoding chip receives an AS-Interface chip 19. This receives the bus signals on the input side and is able via its four ports that are initialized that they form four outputs to control four valves.
- the first valve 7 is directly with the active connector 3 connected.
- the second valve 8 is passive Connection element 4 connected behind the active connection element 3.
- the third valve 9 as well the fourth valve 10 follow this via their passive connection elements 5 and 6 in the same Wise.
- the four outputs of the AS-Interface chip 19 are thus occupied.
- valves can be connected via a next active connection element 11, which itself is assigned to the valve 13 and on the input side to the fourth passive connection element 6 connects to be activated.
- a valve 14 can then in turn be connected to it via a passive one Connection element 12 and a further three passive connection elements and thus three valves operate.
- the limit of the AS-Interface standard can be switched on with a maximum of 31 AS-Interface chips 19 reached on an AS-Interface bus line 1.
- FIG. 2 The integration of an AS-Interface chip 19 into an active connection element is shown in FIG. 2 shown.
- Pin1 and Pin2 is the input side Contacts 16 led to the two-pole emergency stop line 15. This is exactly the same as the corresponding output contacts 17 looped through.
- Pin3 and Pin4 the contacts 16 on the input side are connected to the two-pole AS-Interface bus line 1. This is also the same as the pin on the corresponding output contacts 17 of the Connection element looped through.
- the AS-Interface chip 19 engages that on the input side serial bus signal from the bus line looped through the active connection element.
- the The first of its four outputs is the one assigned to the active connection element Valve connected via the electrical valve connection 18.
- the other three outputs of the AS-Interface chips are sequentially connected to Pin5, Pin6 and Pin7 on the output side Contacts 17 out.
- FIG. 3 shows a further advantageous internal connection of the AS-Interface chip 19 with an active connection element.
- This connection element has two special features Connections 18 to control valves.
- only a similar passive connection element or two passive connection elements with one valve connection each via the associated active one Connection element are operated in order to increase the connection capacity on the AS-Interface chip to fully utilize.
- FIG. 4 shows the internal wiring of a passive connection element for operating a Valve.
- Pin1 to Pin4 of the input-side contacts 16 are the same as pins on the output-side contacts 17 connected to the bus line 1 and the emergency stop line 15 through the connecting elements of the valve unit connected in series in a row to lead.
- Pin5 of the contacts 16 on the input side goes to the valve connection 18.
- Pin6 and Pin7 the contacts 16 on the input side are offset in this way from the contacts 17 on the output side connected that they go there to Pin5 or to Pin6.
- Any passive connector contains, like every active connection element, one not shown in the figures Driver transistor, which uses the control signals, the operating voltage for the valve, which tapped by the emergency stop line switches.
- FIG. 5 Another variant for wiring the passive connection element for operation two valves can be seen in FIG. 5.
- Pin7 of the input-side contacts 16 is pin5 of the output-side Contacts 17 connected.
- the preferred embodiment according to the invention results the device for transmitting control signals from the AS-Interface bus line 1 to a valve unit.
