Description

The invention relates to a building services bus system and a method for operating a building services bus system. According to the invention, the term "bus" covers all possible connections (for example, wireless or wired) for exchanging data between devices. For example, multiple devices may be directly connected to a bus line. Alternatively, according to the invention, a plurality of devices may be connected in series with one or more devices each having a connection element of the bus system. The bus system is designed to control one or more building services equipment, in particular operating devices for light sources, or to connect them to one another in such a way that data can be exchanged.

The term "building services equipment" is to be understood as meaning actuators and sensors of building technology, in particular (as actuators) operating devices for illuminants and sensors, such as, for example, light, smoke, motion and presence sensors.

State of the art

In the WO2009 / 121082 a method is presented for driving a lighting control device with a central controller which can receive digital control commands. With a corresponding switch-off command, the connected operating devices are disconnected from the mains. The central controller can continue to receive digital control commands and save the last control command. The central controller can also send the stored commands again after a reclosing command.

A disadvantage is that the central controller stores the control commands that are sent during the switch-off and so the old operating device (almost) can be brought up to date in real time, but in the event that a new operating device is installed instead of taken from the network , the new operating device can not be brought to the configuration level of the removed operating device. Thus, this configuration status is irretrievably lost. It is also disadvantageous that during a replacement of the central controller in this time no digital control commands can be received, since the central controller is the only interface between the operating devices and the outside world. Thus, the information sent to the operating equipment during this time is irretrievably lost.

Thus, an exchange of operating devices can only be done by qualified personnel, since the newly installed operating devices must be manually reconfigured in the worst case. This also entails the risk that personnel confused the individual operating devices and so it comes to an incorrect operation or to a partial or complete damage to the system. The term "system" includes, but is not limited to, the controller that provides the interface to the outside, the bus, and any additional control devices, operating devices, and bulbs connected to the bus. Also, to ensure correct operation of all operating devices, it should be avoided that information is completely lost if the controller, which is the sole interface to the outside, must be disconnected. Again, qualified personnel are required.

Also, the procedure described represents a massive effort, which costs time and money.

According to the invention, the object is to avoid the disadvantages described. For example. If a system or a method is proposed, which can be maintained without detailed knowledge of the technology on the one hand and ensures, on the other hand, that at least less information about the current configuration status or updates eg. During maintenance and / or replacement of control units and / or operating devices are lost. Also, a corresponding control device for controlling a control gear to be designed.

This object is achieved in an advantageous manner by a building services bus system according to claim 1 or a corresponding method and a corresponding control device:
A building technology bus system consists essentially of a network, and at least two connected by the network (preferably decentralized) control units for a building services equipment, in particular a control gear for lighting. In the control devices and / or the building services equipment each configuration data for the operation of the associated building services equipment are stored. The configuration data of a first building services equipment, preferably all building services equipment, are each redundantly stored in at least one second building services equipment of at least two decentralized building services equipment.

In an advantageous development, the configuration data are stored by a first building services equipment on several other building services equipment. This applies in particular in the event that the first building services equipment has an important or even essential functionality for the building services bus system or controls the corresponding method. This can be for example for the Apply headlight on a stage or station or emergency lighting in buildings.

For example, this can be implemented by a first building equipment device preferably several or even each building technology device, in addition to a primary address additionally has at least one secondary address, which differs from the primary address, preferably the secondary address of a building technology device of the primary address of a other building technology device corresponds. In principle, an address in a network is used to enable a specific building technology device to recognize / receive data sent to the specific building services equipment. In this way, a first building services equipment, preferably several or all first building services equipment, not only receive the information or configuration data from the network, which are relevant to the operation of the first building services equipment, but also the information or Configuration data relevant to the operation of one or more other building services equipment.

The building services equipment according to the invention, which can act in such a, preferably decentralized, network contains a unique primary address. This can either, preferably in a changeable manner, be programmed (software or firmware coding) and / or be hardware-coded, for example as a MAC address or the like. It is also possible for the building services equipment according to the invention to determine or assign its primary address from the assigned operating device.

Furthermore, the building services equipment according to the invention additionally additionally contains at least one further secondary address which differs from the primary address. Like the primary address, this can also be programmable and / or hardware-coded. In a development, the building services equipment according to the invention may also have a plurality of, preferably different from each other Sekundärradressen. The building services equipment is able to access from the network information and / or configuration data, hereinafter referred to as data. However, the relevant data is determined based on the primary address and / or the one or more secondary addresses of the first building services equipment. In this case, based on the primary address, the primary data, which are intended for the operation of the first building services equipment, and / or based on the secondary address, the secondary data, which are intended for the operation of at least one other building services equipment filtered out.

In this case, a building services equipment can monitor whether the at least one other building services equipment in the network whose primary address corresponds to one of the at least one secondary address of a building services equipment is active. This can be done at regular intervals, at freely programmable times and / or after a, preferably adjustable, number of operating seconds, minutes or hours.

The control unit controls a building technology device, in particular operating device, which controls a technical device (consumer). The consumer can z. B. be a light. The lamp may essentially include an incandescent lamp, energy saving lamp, halogen lamp, neon tube, LED (or OLED) lamp or LASER or the like. Also, combinations of the mentioned light generators in question.

The light generators may preferably emit in spectral regions of infrared (IR), visible (VIS) and / or ultraviolet (UV) and also in combinations of the spectral regions.

It is also possible that at certain times, in particular times, and / or on explicit request other light mixtures or compositions are desired. For example, it has been found that raising blue levels of light in the morning increases productivity, especially in offices. In the further course of the day, especially towards evening, it is perceived as pleasant, if the red portion is increased. In this way, the light composition can be adapted to the natural biorhythm or support this. This could also be done by the present invention by sending corresponding time-of-day-dependent primary data for the individual building services equipment over the network. In this way, z. B. a chip or spotlight with a particular color, z. B. blue, green, yellow and / or red targeted more brindle.

It is conceivable that the primary data of a building services engineering device determine various selectively controllable, programmable, or alternating light emission characteristics for a luminaire, so that an environment to be illuminated can be set in a desired light. Applications are z. B. stages and / or the building lighting of z. As museums and / or churches, reception halls and / or conference rooms.

It is also possible according to the invention for the light composition and / or brightness to be measured (for example by a charge-coupled device (CCD), spectrometer, a photodiode or the like) for determining an actual value and this value to compare a target value. The change of the primary data for the building services equipment is then determined by the difference between the actual and desired value.

It is inventively conceivable that the primary data for a building technology device to be adjusted when technical changes, eg. B. be made to the cooling of the lamp. If a new, z. B. more powerful, built-in cooling, the maximum power consumption or the energization of the lamp can be increased.

Also, combinations of the illustrated measures are possible.

In a further development, the one building services equipment in the event that the other building services equipment is inactive, a failure, preferably, if a new other building services equipment is determined by a building services equipment, this secondary address of a building technology Device or alternatively the primary address of the new other building services equipment becomes the new secondary address of the one building services equipment. Preferably, the transmission then takes place from the data redundantly stored on the one building services equipment, in particular configuration data, which is the data intended for the other building services equipment, that is to say its primary data, to the other building services equipment. This has the advantage that low-qualified personnel without technical understanding of the building services equipment, the bus system and / or the network can easily install a new building technology device. If different types of building services equipment for different types of control gear are required in the bus system, the appropriate building technology device can be identified, for example, based on specific colors, nameplates and / or mechanical plugs and then installed. In an advantageous development, building services equipment of a first type but are able to store primary addresses of building services equipment of at least one, preferably more preferably any, second type as secondary and in a further development also secondary data of any type.

In a further development, the query whether at least one, preferably several or all, building services equipment are active by a master controller or controller in the network in addition to or instead of at least one, preferably all, building services equipment done. In principle, the use of a master control device has the advantage that the network can appear in a uniform manner to the outside. Without such a master device z. B. two building services equipment in the worst case contradictory information issued to the outside. For example, the operating devices connected to the control units can not only contain consumers (actuators), but also include sensors, for example for determining the light composition and intensity, temperature, humidity, current, voltage and / or power consumption. Also, the master control unit or control unit preferably queries selectively when the network has a low load.

It is also the case that some consumers, in particular lamps, assume the final (quasi) constant emission characteristic and consumption characteristic only after several days of continuous operation (burn-in). Therefore, it may be useful for a master control unit, after a certain burn-in period, to interrogate the emission characteristic and the consumption characteristic of sensors which are both within the network including the consumers (in particular to determine the consumption characteristic) and outside the network (in particular to determine the emission characteristic). As a result, the master control unit can then send new primary data to the building services equipment to produce the desired radiation characteristics.

In a further development, a building technology device can independently report a failure and then deactivate it if an internal fault is detected, and thus full functionality can no longer be guaranteed.

In a further development, the decentralized network is topologically star-shaped. In this case, advantageously, a master control device can be provided which has direct access to the topological node. In this way, data can be sent quickly, preferably quasi simultaneously, preferably in real time, from the master control unit to one or preferably several, and preferably all, building services equipment. Thus, there is no noticeable time delay between the individual building services equipment in a reconfiguration with primary data (and consequently also with secondary data).

Also, the system may include at least one empty building services equipment, preferably, to take over in case of failure of a building services equipment its tasks. This embodiment is particularly useful in combination with a star-shaped network, since the position of the individual building services equipment is topologically irrelevant in a star-shaped network. So a building control unit can easily do the Task of another building technology device.

In an alternative embodiment, the decentralized network is annular. This means that a building technology device is directly connected to both topologically adjacent building technology devices. However, the individual building services devices are at least indirectly connected to every other building technology device via the network and other building technology devices. Also in this embodiment, a master control device is provided in a development.

In this alternative embodiment, the at least one, preferably each, building services equipment as a secondary address on the primary address of at least one topological, preferably of both, directly adjacent building services equipment.

It is also possible according to the invention in the alternative embodiment that the at least one, preferably each, building services equipment as secondary address has the primary address of at least one preferably topologically remote building equipment.

The term network or the bus covers all wired and wireless transmission of data. Non-exhaustive list of possible networks Digital Addressable Lighting Interface (DALI), Cable Area Network (CAN), Media Oriented Systems Transport (MOST), Ethernet, TCP / IP, WiFi, European Installation Bus (EIB) , Bluetooth, fiber or powerline networks. However, combinations of the enumerated networks are also possible.

The invention will be explained in more detail with reference to the accompanying drawings.

5 shows in addition to the in 4 illustrated embodiment of the invention as a master control unit is integrated into the network.

1 teaches a controller 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n , which is in a network 3 can be used with n controllers, where n is a natural number greater than 1. The data is sent over the network 3 sent. The term data includes configuration data for the controller 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n , software and firmware updates, general values, which are fed into the network via sensors via the control unit, and the like.

In the network 3 with n controllers are still at least two building equipment 7 which also provides data over the network 3 can send and receive. The term data also includes configuration data for the building services equipment 7 , Software and firmware updates, general values, which are fed via sensors via building services equipment into the network and the like. Each building technology device has a primary address 11 and a secondary address 12 on. As the above described data over the network 3 can be sent, in principle, any control unit 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n and every building technology device 7 access the data sent.

Based on the unique primary address 11 may be the first building services equipment 7 however, filter out the data for the first building services equipment 7 are determined. The primary address 11 is either hardware-coded or can be determined by software. The secondary address 12 is also hardware-coded or software-determined, with the secondary address in most applications 12 certainly be software determined. This will be explained later in more detail.

The over the network 3 Data sent contains a header, which corresponds to the primary address 11 and / or the secondary address 12 is adjusted. If a match is found, the data is downloaded and forms and / or updates the primary data and / or secondary data. They form the basis of the secondary address 12 received data, the secondary data, which are preferably only stored or - at least in this building services equipment 7 - not further processed. Analog form the basis of the primary address 11 from the first building services equipment 7 received data the primary data 11 , These can also be saved or used for updating. In contrast to the secondary data are usually the primary data of this building services equipment 7 however, in this building technology device 7 further processed. More precisely, the primary data determine at least substantially exclusively the configuration of this building services equipment 7 ,

In principle, a first control unit 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n and / or first building services equipment 7 also the primary data and / or the secondary data of another, from the first building services equipment 7 different, building technology device 7 Interrogate. Alternatively, a master controller 8th a first building technology device 7 cause the primary data and / or the secondary data over the network 3 to send. The third possibility is that every first building equipment device 7 periodically sent its primary data to ensure that the remaining first building services equipment 7 containing the primary data sent as secondary data 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n need to be up to date. The fourth possibility is that every building technology device 7 his primary data when removing the building services equipment 7 , preferably independently, shipped. Thus, it can also be ensured that the primary data of each building services equipment 7 redundant in another building technology device 7 available. In a further development, the primary data of a removed building technology device 7 not only stored in the building services equipment, which as a secondary address 12 the primary address 11 of the taken out building technology device 7 has, but additionally in an empty control unit 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n or an empty building services equipment 7 so that even in the case that the building services equipment 7 , which contains the extracted primary data as secondary data, the data in the network is damaged. In principle, this means that every building technology device 7 be configured to check whether both its primary data and its secondary data at least once, preferably several times in another building services equipment 7 and / or controller 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n (redundant) are stored.

A control unit 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n is trained a building technology device 7 , in particular a control gear for bulbs 9 to control. This is done via an interface 17 between the controller 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n and the building services equipment 7 ,

In the event that the controller 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _{n has} a hardware-encoded primary address, which for the functionality of the other network 3 must be preserved, is the hardware encoding of the primary address 11 physically fixed to the building services equipment 7 connected. The control unit 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n can preferably access the hardware identifier via the interface, so that a newly built-in control unit 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n always a unique hardware-encoded primary address 11 which has through the building services equipment 7 is determined.

Furthermore, the building technology device has 7 via at least one preferably two or more lines to illuminants 9 head for. The exact control is determined by the configuration data, which is the primary data of the controller 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n form, determined. In 2 is a building technology bus system according to the invention 2 shown. This includes several controllers 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _{n are} as in 1 where n is a natural number greater than 1. The number of control units n is according to the invention not limited above. Only the network standard used can lead to restrictions in individual cases. The individual control units 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n are through a network 3 connected with each other. Each of the controllers 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n can go directly to the network 3 access without any other control device in any form access to the network 3 would limit. This is also called star network architecture. From a control unit 1 _k data sent with k = 1 ... n passes through the network 3 always directly to all other control units 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n . In this way, a fast data exchange, preferably in real time, ensured so that the network can ensure the redundancy in real time, in order to achieve in this way a hedge of all configuration data. In the network 3 with n controllers are still at least two building equipment 7 which also provides data over the network 3 can send and receive.

Each control unit 1 _k and / or building technology device 7 is capable of at least one other building services device 7 to identify and to store its primary data as secondary data.

The assignment, which building technology device 7 which primary data of another building technology device 7 as secondary data stores, for example, due to the primary address 11 happen. Each of the building equipment device 7 determines, for example, the building services equipment 7 with the next higher and / or lower primary address 11 and stores its primary data as secondary data. The building technology device 7 with the lowest or the highest primary address 11 instead stores the primary data of the building services equipment 7 with the highest or lowest of the primary address 11 in the case that no lower or higher primary address 11 in the building services bus system 2 or network 3 is available.

In principle, any other method is possible as long as it is ensured that the primary data of a first building services equipment 7 , preferably all building services equipment 7 at least simply redundantly stored.

Alternatively, in another embodiment in FIG 3 illustrated embodiment, the management of in 2 illustrated and described building technology bus system 2 additionally or exclusively by a master control unit 8th happen. This also intervenes directly or indirectly on the network 3 to.

The master control unit 8th can check if one, preferably several, especially preferably all, certain primary address 11 in the network 3 is available. Alternatively or additionally, at least one, preferably several or all, building services equipment 7 regular signals over the network 3 to the master control unit 8th send. The master control unit 8th can uniquely identify which building services equipment based on the primary addresses contained in the received signals 7 is present, removed and / or reinstalled.

Depending on this, the master control unit 8th then take appropriate action to ensure that the primary data of any existing building services equipment 7 at least once, preferably several times, in the building services bus system 2 remain. Also, the master controller 8th be formed, primary data of control devices and / or building services equipment 7 short-term and / or long-term storage. In this case, the master control unit 8th if necessary or regularly, the primary data of the individual ECUs 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n and / or building services equipment 7 demand. In a training provides - as in the comments too 1 described - the master control unit 8th that the primary data from a currently removed or inactive control device 1 ₁ , 1 ₂ , 1 ₃ , 1 ₄ , ... 1 _n-1 , 1 _n and / or building technology device 7 in an "empty" controller 1 _k and / or building technology device 7 be stored so that even after the removal or inactivity of a withdrawn or inactive control device whose primary data at least twice, ie redundant, in the building services bus system 2 are stored.

In 4 a further embodiment of the invention is shown. Unlike in the 1 - 3 described bus system, the network is designed annular. Every building technology device 7 is connected with two topologically direct neighbors. This means that a building equipment device 7 not - as in 1 described - must be able to with any other building services equipment 7 communicate directly, but with the two directly adjacent building services equipment 7 ,

With this network topology is achieved that the network 3 not with data from a variety of building services equipment 7 can be flooded.

Thereby, that topologically directly adjacent building engineering device 7 are directly connected to each other, the primary data of a building services equipment 7 fast with the secondary data of one or the two directly adjacent building services equipment 7 be matched. Also, the administrative burden of such a network is much lower than in the networks, which in the remarks in 2 and 3 since only a comparison of the primary data and the secondary data with one, preferably both, directly adjacent building services equipment 7 must be made.

In a development, it may also be provided that the primary data of a building services equipment 7 in a neighboring building equipment device 7 are stored redundantly as secondary data, with the adjacent building services equipment 7 can be done by means of a query via an additional communication channel. For example, the building services equipment 7 be equipped with a radio module to transmit radio signals and radio signals of adjacent building services equipment 7 to recieve. On the basis of the received radio signals and preferably the signal strength, the building services equipment 7 determine which building services equipment 7 are arranged adjacent. However, it can also be a detection based on the radiated light, for example, especially when the building services equipment 7 , which store secondary data redundantly, are designed as operating devices for lamps. For example, the operating devices can emit coded light signals via the light source, on the basis of which the adjacent building services equipment 7 can determine which building services equipment 7 are arranged in the neighborhood.

In a development, it may also be provided that the primary data of a building services equipment 7 in a topologically far away building technology device 7 be stored redundantly as secondary data, since overvoltages occurred in most cases locally, ie not on the entire building services bus system 2 impact. In particular, software-coded data, in particular configuration data, which are generally stored in erasable memories which store the primary data of a first building services equipment 7 are often unintentionally erased by such surges. Since such a local overvoltage only on a building technology device 7 and the topologically adjacent building services equipment 7 By storing the primary data of one, preferably all, building services equipment is affected 7 in, preferably in each case at least, a topologically removed building services equipment 7 a higher reliability of the building technology bus system 2 reached. However, it takes a relatively long time to get into one of a first building equipment device 7 topologically removed building technology device 7 data stored as secondary data on several other building services equipment 7 in series up to the first building services equipment 7 reach.

Among other things, since the administration of such an annular network 2 is relatively complicated, in addition - as in 5 shown - a master control unit 8th as part of the building services bus system 2 be provided. In principle, it is possible according to the invention that the management of the building technology bus system 2 over the annular network 3 happens. In the annular network 3 In addition to the data (eg configuration data, software and firmware updates, ...), the administration data must then be transferred. The disadvantage is that the transfer of the administrative data of building services equipment 7 the relatively far away from the master control unit 8th are, can take a relatively long time, leaving no or only incomplete information about the network 3 and the building services equipment 7 in real time.

Also have in the network 3 if it is interrupted in at least two topologically different places, possibly all building services equipment 7 between these locations, no longer via a connection to the master control unit 8th , This therefore has no information about these building services equipment 7 , In a development according to the invention, which in 5 is shown, the transfer of data between the individual building services equipment happens 7 over a data network 3a , Its mode of operation for the data transmission, in particular of software, firmware updates and / or the exchange of configuration data and / or similar data, is analogous to that in the comments on the in 4 illustrated embodiment.

The administration of the building technology bus system 2 happens either instead of or in addition to the administration already described over the network 3 or data network 3a via a topologically star-shaped management network 3b , wherein the master control unit 8th the central point of the management network 3b occupies. The management network 3b can be a direct connection with at least one, preferably several or all, building services equipment 7 of the building technology bus system 2 produce. In this way, that is, preferably central, master control unit 8th always capable of direct inquiries to at least one, preferably all building services equipment 7 to judge or these may be in periodic or at an event such. B. the removal and / or installation of a building services equipment 7 direct contact with the master control unit 8th take up.

In a continuing education can (but does not have) the master control unit 8th also on the data network 3a access. For example, the building services bus system 2 be supplied with software or firmware updates, other data updates and / or completely new data in this way.

In one embodiment of the invention, it may also be provided that the primary data of a building services equipment 7 in a topologically not directly adjacent building technology device 7 be stored redundantly as secondary data, since, for example, not every lamp is required for an escape route lighting, but only one each at a certain distance to the next light for escape route lighting. Therefore, for example, by programming or selection by a user such as an installer of the system individual building services equipment 7 are selected as devices which then store secondary data redundantly. In this way, an increased reliability can be ensured just for the emergency lighting such as emergency exit lighting, while still meeting the requirement for lower energy consumption in emergency lighting case, since not all lights must then be operated. The selection by a user of the building services equipment 7 , which store secondary data redundantly, for example, over the network 3 or via a further configuration interface such as via a wireless interface such as RFID or NFC done. The assignment and selection of the building services equipment 7 , which store secondary data redundantly, can also be done via an existing building plan, which is connected to the building services bus system 2 is linked.

Unless the building services equipment 7 , which store secondary data redundantly, are designed as operating devices for light bulbs, these can be designed to, depending on the failure of other building services equipment 7 not only to take over their secondary data, but also to adjust the light output by the connected bulbs. For example, such an operating device can increase the brightness, additional Control output channels or activate or deactivate external optics to change the light output. In this way, not only can an increased security with respect to the data be made possible, but also with regard to the lighting, which may be important in emergency lighting, for example. In the case of emergency lighting can also be provided that optionally in emergency case, a supply of additional light sources from an emergency battery.

All described embodiments and dependent claims are - as far as technically feasible - combined.
