Installation with DALI bus

Technical area

The invention relates to an installation with a plurality of terminals, which communicate with each other via a provided in the installation DALI bus and each of which has one of a maximum of 64 individual short addresses over which the terminal is addressed. Such an installation is, for example, a busbar system.

A typical busbar system works with lights or other terminals that have a ballast. The ballast can be digitally controlled via an interface. For this a control protocol is used. A well-known control protocol is the "Digital Addressable Lighting Interface" (DALI) Each ballast belonging to a terminal can be controlled individually via a DALI short address, which makes it possible, for example, to detect failures, switch devices on and off, and then dim them To control light colors, as well as to change light distributions by dimming operations of lamp groups or LED groups or to move over a controllable mechanism.

State of the art From DE 102 12232 Al a busbar with data line is known. Via the busbar, terminals are controlled according to the DALI protocol. The functionality and properties of such DALI installations are explained in detail in the DALI manual (www.dali-ag.org/c/manual_englishlanguag.pdf). The DALI standard works in such a way that at initialisation a maximum of 64 short addresses are used

(sometimes also with individual address) can be awarded. One or more DALI control units can therefore address a maximum of 64 end devices individually (see DALI manual p.25 point 4.8). Furthermore, each terminal can be assigned to a maximum of 16 groups. The group address is provided for this purpose. The manual requires that the limit of up to 64 individual addresses and thus terminals not be exceeded.

DE 102 12232 A1 also discloses the remote control of the terminals via an infrared or radio link. The associated remote control device is specially configured for this application.

Disclosure of the invention

It is an object of the invention to provide a DALI installation of the type mentioned, can be connected to the little effort more than 64 devices and addressed.

It is a further object of the invention to simplify the control of such an installation and to make it cheaper.

According to the invention the object is achieved in that in addition to the maximum of 64 terminals, which are accessible via a short address, additional, maximum 16 terminals are connected, which also communicate via the DALI bus and which can be addressed via one of a maximum of 16 group addresses, the the additional terminals are assigned individually and clearly. The object is further achieved in that each terminal with a unique short and / or group address represents a group of one or more terminals that communicate identically. The Finally, this object is also achieved in that each terminal has a random address in addition to the short address and means are provided for the transient response of the terminal with the short address, which is temporarily assigned to the terminal with the help of the random address. Control over the short address takes less time than via the random address. The number of transferred

Data packets are smaller when using the short address. Thus, a short address is first assigned to a terminal for the control. The random address is used for this. Then the control is performed. Subsequently, the short address is deleted from the terminal again and is available for further use with other terminals.

The invention is based on the knowledge common to all solutions that the maximum number of connectable and addressable terminals can be increased to a value above 64, if the group address and / or random address is suitably used with the short address. Different scenarios are possible. If the number of terminals is below 64, the busbar arrangement can be operated with the known addressing. If the number is above 64 but below 80, it is sufficient to additionally use the group addresses for the additional maximum of 16 terminals. If additional terminals are connected, which are operated in the same way as other terminals together, they can be connected

Terminals are represented by a short or group address addressed terminal. These terminals of a common group then communicate in a similar way. Each terminal from such a common group receives the same control commands. The proxy terminal returns the same state value for all terminals of the group.

A preferred embodiment of the invention therefore relates to an installation, and in particular a busbar, with means that make a selection of the appropriate mode according to the number and type of terminals. Such an installation is characterized in that means for allocating addresses in accordance with the number of terminals and terminal groups are provided for optimizing the data transfer rate in the bus, wherein (a) addressing via the short address of the terminals takes place when fewer than 64 terminals are connected;

(b) the addressing takes place at 64 to 80 terminals via individually assigned short and group addresses of the terminals; and

(c) the addressing is carried out at more than 80 terminals via the terminals transiently, with the help of the random address assigned short and / or group address.

It is understood that other combinations of addressing with short, group and random address are possible.

It can be used instead of a single terminal and a similarly communicating terminal group, with each group two short addresses are required. A short address receives the proxy terminal. The other

Short address is used to control the other terminals of the group, but not to poll the status. The maximum group number is then 32.

In a particularly preferred embodiment of the invention, the installation comprises a busbar system, to which the terminal devices can be connected. The

Busbar system is not only used for communication via the bus, but also for power supply and mechanical attachment of the terminals at any point within the rail system.

According to a method according to the invention, each terminal is only one unique

Assigned address selected from the short and group addresses. Thus, in addition to the 64 short addresses, as known from the prior art, 16 group addresses are available. This increases the number of connectable terminals to 80. Furthermore, in the case of a group of similarly communicating terminals, only one representative terminal can be assigned an address. This further increases the number of terminals that can be controlled via the same bus system.

To further increase the number of terminals, one or more terminals can be addressed only with a transiently assigned short address based on the random address.

In a particularly preferred embodiment of the invention, the terminals are shown in a floor plan and the assignment of functions and properties is graphically. The allocation of the addresses for the terminals then requires no name of the terminals and input in tabular form. Rather, the location of the terminals is plotted in a floor plan graphically. The assignment of the addresses can then take place, for example, to drag the address to the terminal by means of a mouse on a screen. The procedure makes the assignment of addresses particularly clear and comprehensible.

Advantageously, the data transfer rate is optimized in the DALI bus of an installation with means for address assignment in accordance with the number of terminals and terminal groups in a method that is characterized by the

Steps:

(a) addressing via the short address of the terminals, if less than 64 terminals or similarly communicating terminal groups are connected;

(b) addressing at 64 to 80 terminals or similarly communicating terminal groups via individually assigned short and group addresses of the terminals; and

(c) addressing with more than 80 terminals or similar communicating

Terminal groups via the terminals temporarily assigned combination of short and random address and / or group and random address. So before a selection of the type of addressing takes place, it is determined how many terminals should be connected. In particular, when the number of terminals is higher than 64, the addressing is not made exclusively through the short address.

An inventive installation with a plurality of terminals and a control unit, which communicate with each other via a DALI bus provided in the installation, is characterized in that

(A) the control unit comprises a transmitting and receiving device for wireless data transmission, and

(B) the controller is set up with a program, via which a communication of the controller with a web browser can be produced, wherein

(c) the controller sends state data about states of the terminals to the web browser.

In particular, the status data can be sent on request of the web browser.

The installation includes not only the terminals, so lights and the like, a control unit. The control unit receives control commands from a user. For this purpose, the control unit is provided with a transmitting and receiving device. The send and

Receiving device communicates wirelessly. This avoids complex cabling. The controller can be used as the terminals at any point. The situation can be changed without structural measures. The user can freely move in the same to control and / or configuration of the system, which is necessary for larger installations. The control unit comprises a program, via which a communication of the control unit with a web browser can be produced. The program, which is set up on the control unit, can be accessed via an Internet Protocol address be addressable server program. Upon request, the controller sends status data about states of the terminals to the web browser and receives control commands from the web browser. In other words: The controller can be addressed by any standard web browser. This will make the construction of your own remote control and proprietary software as well

Installation on the HMI device avoided.

The transmitting and receiving device for wireless data transmission may include a wireless local area network (WLAN to IEEE 802.11) interface. Then any device that has a web browser and a WLAN interface can communicate directly or indirectly with the controller. Indirect communication takes place, for example, via an intranet. These devices include WLAN-enabled personal computers, notebook computers, mobile telephones (cell phones) and the like. A separate hardware and software for setting up and controlling the DALI installation is no longer required.

Preferably, the installation comprises a busbar system to which the terminals and the control unit can be connected. Since then not only the terminals but also the control unit can be installed in virtually any spatial position, the use of a busbar system offers the possibility of optimizing the quality of the

Radio link. The control unit can be mounted in the position where the best wireless connection to wireless devices exists.

In one embodiment of the invention, program files can be retrieved using client-side programming on the control unit, with which control signals for

Controlling the states of the terminals can be generated. The generation of these control signals can be done in a particularly user-friendly graphical interface. Such retrievable program files may be, for example, Flash files, Java files or similar files. By calling the IP address of the controller such program files, such as flash files o.a. accessed through the web browser. About these

Program files can be offered user-friendly choices for terminal devices and settings for brightness, location, etc. If the user has a Selection or setting, a control signal is generated by the program file. The control signal is sent to the control unit and forwarded from there via the DALI bus to the terminal.

Preferably authorization data can be queried with the program in the control unit.

Classified access rights can also be assigned. Depending on which user authorizes himself to the control unit, more or less rights are assigned to settings.

In a preferred embodiment of the invention, the program in the

Control unit to another program part, with which the controller is set up. This further program part can be called, for example, via another IP address with a different authorization and other access rights. The control unit can be set up via this additional program section. The device comprises in particular the allocation of access rights and authorization conditions and the

Installation of new devices.

An inventive method for controlling an installation with a plurality of terminals, which communicate with each other via a DALI bus provided in the installation, and at least one addressable via an Internet Protocol address

Control unit, is characterized by the steps:

(a) retrieving program files from the controller to control the states of

Terminals via a web browser; (b) generating control signals for controlling the states of the terminals by means of the retrieved program files; and (c) transmitting the control signals to the controller.

The method is used in particular with an installation comprising a busbar system. In a particularly preferred embodiment of the invention, the wireless connection is established directly between an operating device with a web browser and a transmitting and receiving device and the control unit. In this case, the wireless connection to the control unit can be established by a control unit connected to the Internet or another network with a web browser via a transmitting and receiving device connected to the Internet or other network.

Preferably, the transmitting and receiving device connected to the Internet or other network is a Wireless Local Area Network Access Point. Communication then takes place from the HMI device with a web browser to WLAN access

Point. The WLAN access point establishes the connection to the control unit. Such WLAN access points are already commercially available technology, which are widely used in the private and commercial sector. They allow multiple users to access the control unit. They also allow access from any location. It is understood that this technology is preferred because of its widespread use, but comparable technologies that enable communication of the controller with the Internet can also be used.

Preferably, the operating device is a mobile device or a mobile data processing system with a transmitting and receiving device. Then the

Connection via a wireless LAN access point or directly to the control unit.

Embodiments of the invention are the subject of the dependent claims. An embodiment is explained below with reference to the accompanying drawings.

Fig. 1 illustrates the addressing in more than 80 terminals. Description of the embodiment

FIG. 1 shows a bus bar, generally designated 10, with a data line. Such busbars are known from DE 102 12232 A1 and therefore need not be described in detail here. The bus bar 10 is an elongated Metallprofϊl, in which a data line in the form of a DALI bus and a line for the power supply are housed. The profile is the same over the entire length. It is designed such that various terminals 12 can be hung anywhere in the busbar and connected to the bus. Such devices

12 are in particular lights. But it can also be provided sensors, mechanical drives or the like. The rail is fastened to the ceiling of a building. Only when determining the type of use and type of use, it is necessary to attach the lights. This allows a high flexibility in the use of buildings. In the present embodiment, the current flowing through the terminals is measured. If a maximum value is reached, the user receives a signal.

A control unit 14 can also be used at any point in the busbar 10. The control unit 14 comprises a processor, a memory and a WLAN transmitting and receiving device. The WLAN transmitting and receiving device is represented schematically in FIG. 1 by the antenna 16.

The control unit 14 controls the terminals 12 suspended in the busbar. To this end, it sends control commands via the data bus and queries the states of the terminals. The control commands and states relate, for example, to the position and brightness of the luminaires and the position of the mechanical drives. The control commands can also concern entire lighting scenarios.

The control unit 14 in FIG. 1 is connected directly to a portable control unit 18 via the transmitting and receiving unit. In the present case, the operating device 18 is a

Smart Phone, PDA, Tablet PC or Labtop [RWEi]. This is illustrated by an arrow 22. The operating device 18 is also provided with a transmitting and receiving unit, represented by an antenna 20.

FIG. 6 shows how the connection 22 takes place. The operating device 18 has a web browser 24. A web browser, e.g. Internet Explorer from Microsoft, is a

Computer program for viewing websites on the World Wide Web. Various types of documents can be displayed, especially Flash or HTML pages. They provide a standardized user interface for retrieving and sending information. The web browser 24 installed on the operating device 18 is started and the Internet Protocol address (IP address) of the

Control unit called.

On the memory of the controller 14, a web page with flash program files is stored. The control unit 14 forms a web server. When the IP address is called, the web page is sent by the receiving-ready control unit 14 directly to the operating unit 18. This is represented by the arrow 26 in FIG. Neither the control unit 14 nor the operating unit 18 need in the present embodiments of Figure 1 to 4 an Internet connection.

On the website sent from the control unit 14 to the web browser 24, after authorization by password query, states of the terminals and control means are displayed. The control means allow adjustment of the various lighting parameters. For example, a bar is displayed for each luminaire, showing the degree of dimming [RWE2]. It also indicates if a light is on or off. By alphanumeric or graphical input of

Values are generated by control commands [RWE3]. These control commands are sent to the controller 14. This is represented by an arrow 28 in FIG. An additional own program for the control of the terminals is not required on the operating unit 18. Also, any HMI device that has a web browser and a suitable wireless transceiver can be used. In an alternative embodiment, an operating device is used which allows multiple transmission paths. FIG. 2 shows an alternative transmission path. Here, the connection between the operating device 18 and the control unit 14 is also made via a WLAN. However, the connection does not take place directly but via a central WLAN access point (WLAN access point) 30. The operating device 18 sends control signals to the central access point 30. This is represented by an arrow 32. The central access point 30 forwards the control signals to the control unit 14. This is represented by an arrow 34. In the reverse direction, the controller 14 sends the website with status data to the HMI device 18 and performs the authorization. The advantage of this indirect connection is that a higher range can be achieved.

Typically, the range of a wireless Wi-Fi connection is a few tens of meters. It also depends on the attenuation in the structural conditions. Through a central access point, the range can be significantly increased.

FIG. 3 illustrates that with a central access point 30 a plurality of operating devices 18,

18 'and a plurality of control devices 14, 14' can be achieved. It goes without saying that more than two control devices 14, 14 'and more than two operating devices 18, 18' can also be used and only two are shown here for the sake of clarity. As in the exemplary embodiment according to FIG. 2, the WLAN connection takes place wirelessly via connections 32, 32 'to the central access point 30 and via connection 34, 34' to

Control unit 14, 14 '.

Instead of a wirelessly connected mobile control device 18, a desktop computer 38, 38 ', such as a laptop or a stationary workstation computer can be used to generate the control commands. This is shown in FIG. Of the

Calculator is also set up with a web browser. The connection is made via a network cable 40, 40 '. Such a network cable is an Ethernet, for example CAT 5 IOOBaseTX. The desktop computer 38, 38 'is connected to a router 36 with such a network cable. The router 36 in turn is connected to the central access point 30 via another network cable 42. The central access point 30 establishes a wireless WLAN connection 34 to the control unit 14, as has already been described above with reference to FIGS. 1 to 3. It is understood that whenever a central access point 30 is used, other control devices 18 can be used, which are connected via a wireless connection.

While the connection from the operating unit 18 or computer 38 to the control unit of the embodiments described above has been made directly or via a central access point 30, this can also take place via the Internet 44 or another suitable network. This is shown in FIG.

Mobile operating devices 18, such as mobile devices, can gain access to the Internet via GPRS or UMTS. This is represented by arrows 46, 46 '. This connection is not a short-range radio link such as the WL AN connection mentioned above. A Wi-Fi connection can only be made within the building or other short distances. The GPRS or UMT S connection is via the mobile network and has an international reach. The access of mobile devices to the Internet is known and the necessary technical details do not need to be explained.

Stationary workstation computers 38 ", 38 '" can also be connected to the Internet 44 via known transmission paths 52, 52'. In the present embodiment representatively two workstation computers 38 ", 38 '" are shown, which are connected to the Internet.

The router 36 already described with reference to FIG. 4 is connected to the Internet 44 via a network cable 50 and a modem 48 in this exemplary embodiment. For example, the connection between modem 48 and Internet designated 54 may be over a high speed connection, such as a digital subscriber line (DSL). It is understood that instead of separate components access point 30 and routers

36 also a so-called "wireless router" can be used, in which both Components are integrated in a common device. The use of a "DSL router", in which a modem is integrated, is of course possible.

Moreover, the arrangement of the embodiment shown in Figure 5 is comparable to the exemplary embodiment of Figure 4. The same components are provided with the same reference numerals.

The use of a central access point has the advantage, especially in large buildings, that the central access point 30 can be positioned at a location that is optimized with regard to the quality of the radio connections to a plurality of control devices 14, 14 '.

Figure 7 shows an embodiment analogous to the embodiment in Figure 5, in which instead of a wireless WLAN connection between a controller 14 and access point directly, a wired connection 60 via a network cable with the

Router 36 is made. The control unit 14 is arranged separately from the busbar 10 and connected to the busbar 10 via a DALI connection 62. An access point 30 'is used in this embodiment only for producing a wireless connection 64 with control devices 18 ", if they are not connected to the Internet 44, as is the case with the operating device 18' the case.

With the input of control commands via the web browser connected to the power rail 10 terminals 12 can be controlled. For this, the arrangement must first be set up. In this case, the terminals 12 are provided with an address.

Calling a further IP address, which differs from the above-described IP address to the controller, also makes it possible to set it up using a web browser. The control unit 14 sends a web page on which the floor plan of the building and the course of the busbars is displayed [RWE4]. The position of the terminals can now be entered in the floor plan, eg with the mouse. Each terminal receives an address with which the communication takes place via the DALI interface. An optimization algorithm provided in the control unit decides, in accordance with the number of terminals, the type of addressing. With fewer than 64 terminals, which are assigned to the control unit, the addressing takes place, as shown in FIG. This is the well-known, conventional DALI addressing concept. each

Terminal, represented by the subscriber TLN, which is numbered in the first row in FIG. 8, receives a unique short address KA. The short address is indicated for each terminal in the second row in FIG. It is understood that here only by way of example, the first four and the last of the 64 participants are shown to ensure clarity. About the short address, the terminals

Control commands are received and states are queried.

Furthermore, each terminal has a group address GA. This is shown in Figure 8 in the third row. The 64 devices share a maximum of 16 group addresses. They make it possible to use a control command to reach several terminals with the same group address. A status query is not provided.

The assignment of the short address takes place with the aid of the random address (Random Address), which is designated RA in FIG. 8 and is indicated in the fourth row. The short address is set using the random address during the initialization process.

If more than 64 but less than 80 terminals 12 are to be connected to the busbar 10, the optimization algorithm decides that the assignment of the addresses takes place according to the concept illustrated in FIG. It can be seen from the number of participants TLN in the first row that a total of 80 terminals can be connected. The first 64 participants each receive one of 64 short addresses. The remaining 16 participants do not receive a short address. This is shown in FIG. 10 in the second row KA for the short address. These terminals having the subscriber numbers 65 to 80 in Fig. 10 receive a group address of 1 to 16. The terminals designated by subscriber numbers 1 to 64 do not receive any

Group address. In this way, all 80 terminals have a unique address. Both addresses allow both the controller and the query. FIG. 9 shows an addressing concept in which the terminals are controlled in groups. Any number of terminals can be represented by a representative, as shown in the first row in Figure 9. Again, more than 64 devices are possible. Up to 16 functional units of passive DALI

Participants are formed. These are controlled jointly by a DALI group address GA. This is shown in the third row in FIG. The query is made by the respective deputy. Only the representative of the functional unit has a short address. This is shown in the second row KA in FIG. The remaining substitutes do not receive an address for a query. All queries, with one byte as

Answer, will be put to this deputy.

With a number of terminals of more than 80, which are not groupable, the control takes place via a combination of the short address with the random address. This is shown in FIG. In this case, the same short address is used for several terminals.

This is shown in Figure 11 in the second row. The control then takes place via the short and group address GA (third row). The query is made via a substitute. This is addressed via a temporary short or group address, which in turn is assigned by the unique random address (fourth row). Following the query, the original common short address is restored. In this way, up to 79 functional units can be addressed with multiple terminals.

It is understood that the addressing mode is independent of the transmission paths.
