Description

Electrical installation arrangement, and method for operating an electrical

installation arrangement

The invention relates to a display / control unit having a data processing unit for evaluating status signals and for generating control, triggering, display and / or information signals, as well as having at least one first interface for receiving the status signals of at least one measurement / evaluation unit and / or or at least one switching device, and for transmitting the control and / or release signals to the measurement / evaluation unit and / or the switching device, and at least one second interface, which is designed as an active radio interface, for transmitting the information signals to a user terminal and receiving the Control and / or trigger signals from the user terminal. There are circuit breakers with sensors and a control device, as well as with a wired interface for transmitting the sensor data or tripping signals within the circuit breaker known. There are also known switches with a wireless interface for exchanging current data with other "subscribers", such as other switching devices or a PC.

A disadvantage of such display / control units is that it only evaluates the data of a single switching device or a single, arranged in the switching device measurement / evaluation. As a result, of necessity, each switching device has such a display / control unit. This requires another device, such as a user terminal connected to the circuitry, such as a PC, to illustrate the status of the circuitry at a central location. This requires that the user terminal in question be constantly turned on and connected to the circuitry to constantly monitor the entire circuitry. Without an active user terminal, each switching device "works" separately and on its own, so that the detection of physical parameters in one of the switching devices, which could indicate an impending defect, can not be evaluated, or can be compared with other measurements in other switching devices. A selective selective triggering of individual switching devices and the selective selective switching off individual switching sections is therefore limited or not possible, which can lead to both the risk of the circuitry and the people in their environment, too frequent triggering to unnecessarily frequent failures and the associated costs. The object of the invention is therefore to provide a display / control unit of the type mentioned, with which the mentioned disadvantages can be avoided, with which the safety and reliability of a circuit arrangement can be increased, and with which the equipment and installation effort in the field Circuit arrangement can be reduced.

According to the invention this is achieved in that the first interface is designed as an active radio interface.

As a result, the display / control unit can be separated from the measurement / evaluation unit and / or the switching device and spatially arranged elsewhere. As a result, it is also possible to control a plurality of switching devices with a single display / control unit or to receive, process and monitor the status signals of a plurality of measuring / evaluation units. This makes it possible with a single display / control unit to control or control a predeterminable number of control units and / or measuring value units. This allows a central display / control unit to gain a better overall view of the electrical processes in electrical circuitry and to better control errors by e.g. It is also possible to switch off switchgear which can still be within predefined limits without a PC having to be constantly switched on and connected to the circuit arrangement. As a result, the safety in an electrical circuit arrangement can be increased. In addition, switching devices can be prevented from switching off when the display / control unit recognizes that this is a known, only temporary source of error, such as the startup of a machine. Overall, this can be achieved with low Schaltgeräteaufwand, as well as low cabling a good and safe monitoring of the circuit, whereby the safety of the circuit and the people in their environment is increased, and the false alarms can be minimally low, creating such a protected circuit a has high active time. Such, separated from the switching devices display / control unit can also be integrated into a control unit for a home automation system.

In a further development of the invention, it can be provided that the second interface is provided for the transmission and reception of data which are coded according to a substantially standardized data transmission protocol, in particular Bluetooth, GSM, UMTS, WLAN, ZIGBEE. As a result, a wide range of applications can be achieved with many different user terminals.

According to a further embodiment of the invention, it can be provided that at least one display means controlled by the data processing unit, for example at least one LED, preferably a dot matrix display or a screen, is provided. As a result, operating conditions and / or warnings can be displayed and illustrated for the users.

According to yet another embodiment of the invention, it can be provided that the data processing unit is assigned a memory unit for storing received and / or transmitted data. As a result, the operating data as well as the electrical or generally the physical measured values of the circuit arrangement can be recorded and evaluated at a later time. This can be important and helpful for the subsequent understanding of a switch-off process or an error. A variant of the invention may consist in that the first and / or the second interface are designed as a full-duplex radio interface. As a result, a reception or a transmission of control data or of triggering commands is also possible while data is being transmitted or received by the display / control unit itself. This can further increase the safety of the system.

The invention further relates to an electrical installation arrangement comprising at least one switching device, at least one measuring / evaluation unit and at least one display / control unit, in particular a display / control unit according to the invention, wherein the switching device has switching contacts, a switch lock and a trip unit, wherein the measuring / Evaluation unit has at least one sensor for measuring a physical quantity, wherein the display / control unit has display means and / or a data processing unit, and wherein the at least one switching device, the at least one measurement / evaluation unit and the at least one display / control unit each one have first interface for mutual data exchange, and the display / control unit has a second interface, which is designed as an active radio interface, for data exchange with a user terminal.

A disadvantage of such electrical circuit arrangements is that in these only the data of a measuring / evaluation unit arranged in a switching device are merely evaluated by a display / control unit likewise arranged in this switching device. As a result, another device is necessary, such as one with the circuit arrangement connected user terminal, such as a PC, to illustrate the status of the circuitry at a central location. This requires that the user terminal in question be constantly turned on and connected to the circuitry to constantly monitor the entire circuitry. Without an active user terminal, each switching device of the circuit arrangement "works" separately and on its own, so that the detection of physical parameters in one of the switching devices, which could indicate an impending defect can not be evaluated, or be compared with other measurements in other switching devices A selectively selective triggering of individual switching devices and the selective selective switching off of individual switching sections is therefore only partially or not at all possible, which can endanger both the circuit arrangement and the people in their environment, as well as too frequent tripping unnecessarily frequent The object of the invention is therefore to specify an electrical installation arrangement of the aforementioned type which avoids the disadvantages mentioned, which has increased safety and reliability, and which has a reduced number of devices - Has and installation effort.

According to the invention this is achieved in that the first interfaces are designed as active radio interfaces.

As a result, in an electrical installation arrangement, the display / control unit can be separated from the measurement / evaluation unit and / or the switching device and spatially arranged elsewhere. It is thus also possible with a single display / control unit to control several, in particular all, switching devices in an electrical installation arrangement or to receive, process and monitor the status signals of a plurality of measured value units. This makes it possible to control or control a specifiable number of control devices and / or measuring / evaluation unit with a single display / control unit. This allows a central display / control unit to gain a better overall view of the electrical processes in an electrical installation arrangement and better control errors, for example, switching devices can be switched off, which in itself may be within predetermined limits, without that a PC constantly turned on and must be connected to the installation arrangement. As a result, the safety in an electrical installation arrangement or circuit arrangement can be increased. In addition, switching devices can be prevented from switching off when the display / control unit detects that it is is a known, only temporary source of error, such as booting up a machine. Overall, this can be achieved with low Schaltgeräteaufwand, as well as low cabling a good and safe monitoring of the circuit, whereby the safety of the circuit and the people in their environment is increased, and the false alarms can be minimally low, creating such a protected circuit a has high active time. Such, separated from the switching devices DisplayV control unit can also be integrated into a control unit for a home automation system. In this context, it can be provided in a continuation of the invention that the first interfaces and / or the second interface are designed as full-duplex radio interfaces. As a result, a reception or a transmission of control data or of triggering commands is also possible while data is being transmitted or received by the display / control unit itself. This can further increase the safety of the system.

In Weiterfuhrung the invention can be provided that the display / control unit is physically separated from the measurement / evaluation and / or the switching device. As a result, a high flexibility with regard to the arrangement of the display control unit can be achieved. The invention further relates to a method for signal transmission in an electrical installation arrangement, in particular an electrical installation arrangement according to the invention, with at least one measuring / evaluation unit which measures at least one physical quantity, in particular fault current, current, voltage, power and / or temperature, and at least a display / control unit, in particular a display / control unit according to the invention.

There are only known electrical circuit arrangements with switching devices, which comprise a measuring / evaluation unit which controls the trip unit of the switching device. The switching device acts as a self-acting unit.

A disadvantage of such circuit arrangements and the method for their operation is that no current information about the switching state of the electrical circuit arrangement are available to the user. The user learns of an error only when this error has led to a shutdown of the electrical circuitry. This leads to unexpected failures and long service lives. In known circuit arrangements, only the recording of measured values in the region of a switching device is provided. The object of the invention is therefore to provide a method for signal transmission in an electrical installation arrangement of the type described above, with which the mentioned disadvantages can be avoided, with which the safety and reliability of a circuit arrangement can be increased, and with which the equipment and installation costs can be reduced in the circuit arrangement. According to the invention, this is achieved by determining a respective instantaneous value of the physical quantity by the at least one measuring / evaluating unit at predefinable time intervals and transmitting it to the at least one display / control unit, in particular by radio.

As a result, the current value of the physical variable can be checked and / or stored by the display control unit and an alarm can be triggered when a limit value is exceeded. As a result, at specifiable locations in the electrical circuit arrangement, aortable measurement / evaluation units, which can therefore also be arranged independently of a switching device, which transmit their measured values to the display / control unit, contribute to the fact that the display / control unit has a current and Complete picture of the physical conditions can be formed within the electrical circuit arrangement, which allows a comprehensive assessment of security, in particular a determination of imminent error, within the electrical circuitry. As a result, it is also possible to alert a user to an imminent error or risk occurring before the electrical circuit arrangement is switched off, as a result of which the reliability and safety of the circuit arrangement can be increased. In accordance with the invention, it may be provided that the instantaneous value of the physical quantity is transmitted until a new value of the physical quantity has been determined or until an acknowledgment of receipt sent by the display controller has been received by the measured value unit. This will ensure that the current value is really a current value or that the display / control unit has actually received the current value.

In this context, it can be provided in a continuation of the invention that when a predeterminable first limit value of the physical quantity is exceeded by the display / control unit, a first information signal is transmitted by radio to a user terminal, such as a mobile phone or a PC. This can warn a user of an impending error. According to a further embodiment of the invention, in which at least a first switching device with switching contacts, a switching mechanism and a trip unit is provided, it can be provided that when a second predeterminable limit value of the physical variable is exceeded, the display / control unit sends a triggering signal to the first switching device and the trip unit triggers the switch lock, and / or sends a second information signal to the user terminal. As a result, the switching device can be triggered by the display / control unit, wherein the display / control unit can be arranged at a different location in the electrical circuit arrangement. This can be achieved by the display / control unit selective triggering of switching devices. According to yet another embodiment of the invention, in which the first switching device is provided with a sensor for detecting the position of the switching contacts and generating a switching position signal representing the position of the switching contacts, it can be provided that the switching position signal is transmitted to the display control unit. As a result, the display / control unit has an overview of the switching state of the individual switching devices of the electrical circuit arrangement.

In a further embodiment of the invention can be provided that the respective instantaneous position of the switch contacts is sent from the display / control unit to the user terminal. This allows the status of the electrical circuitry to be tracked, recorded, evaluated and / or controlled at a location remote from it. In a further development of the invention, in which the first switching device comprises one of the at least one measuring / evaluation units, and when a third limit value of the physical quantity is exceeded, a triggering signal is transmitted to the triggering unit which triggers the switching mechanism, it can be provided that the display shows A first control signal is sent to the measuring / evaluation unit and the third limit value is changed by the first control signal received by the measuring / evaluation unit. As a result, can be changed by the display / control unit of the third limit whose exceeding leads to an automatic triggering of the switching device. As a result, it is possible to comply with increased safety requirements, for example, or to respond to expected short-term faults, which would otherwise lead to unnecessary triggering of the switching device. The display / control unit can detect, for example, the starting or run-up of a load, which leads precisely to a short-term exceeding of the third limit value in this run-up phase. By automatically detecting the start-up process and adjusting the third limit for this time, both the safe As well as high safety during the rest of the time, since it is not necessary to use a switching device with a third limit, which is so high that the switching device does not trip too often.

A variant of the invention, in which the switching device with a

Reclosing device is operatively connected may consist in that the display

/ Control unit a reclosing signal is sent to the reclosing device and by the received reclosing signal the recloser the

Switching contacts of the switching device are closed. This allows the electrical

Circuitry not only be centrally controlled off, but also turned on again.

Another possible embodiment may be that the instantaneous value of the physical quantity, the first or second information signal, and / or the respective current position of the switching contacts to a display means of the display / control unit is displayed. This allows a user to quickly and centrally

Gain an overview of the status of the electrical circuitry. This is particularly advantageous in widely branched switching devices, which are not arranged in a single cabinet.

The invention will be described with reference to the accompanying drawings in which

Embodiments are exemplified, described in more detail. Showing:

Fig. 2 is a block diagram of a preferred embodiment of an inventive

Display / control unit;

Measuring / evaluation unit; and

Fig. 4 is a schematic diagram of a preferred embodiment of an inventive

Switchgear with an integrated measuring unit.

FIG. 1 shows an electrical installation arrangement comprising at least one switching device

3, at least one measuring / evaluation unit 2 and at least one AnzeigeVSteuereinheit 1, in particular according to one of claims 1 to 5, wherein the switching device 3 switching contacts 31, a switching mechanism 32 and a trip unit 33, wherein the measuring / evaluation unit 2 at least one sensor 21 for measuring a physical quantity, wherein the

Display / control unit 1 display means 12 and / or a data processing unit 11, and wherein the at least one switching device 3, the at least one measuring / Evaluation unit 2 and the at least one display / control unit 1 each have a first interface 6 for mutual data exchange, and the display / control unit 1 has a second interface 7, which is designed as an active radio interface, for data exchange with a user terminal 4, the first interfaces 6 are designed as active radio interfaces.

An electrical installation arrangement according to the invention can be any type of electrical installation arrangement and / or circuit arrangement. Particular preference may be provided electrical installation arrangements for the power supply of operation and / or households.

Inventive electrical installation arrangements comprise at least one switching device 3, at least one measuring / evaluation unit 2 and at least one display / control unit 1, wherein the switching device 3, the measurement / evaluation unit 2 and the display / control unit 1 each have a first, as active Radio interface trained to include interface 6, for mutual data transfer or data exchange.

As a particular advantage of an electrical installation arrangement according to the invention proves that, as in the particularly preferred embodiment shown in Fig. 1, the AnzeigeV control unit 1 of the measuring / Auswerteemheit 2 and / or the switching device 3 can be physically separated, and therefore spatially to another Place to be arranged. It is thus also possible with a single display / control unit 1 to control several, in particular all, switching devices 3 in an electrical circuit arrangement or to receive, process and monitor the status signals 82 of a plurality of measured value units 2. This makes it possible to control or control a specifiable number of switching devices 3 and / or measuring / evaluation unit 2 with a single display / control unit 1.

As a result, a completely new approach to the construction of an electrical installation arrangement is possible. As a result, for example, the measuring / evaluation units 2 can be arranged separately from the switching devices 3. As a result, electrical parameters at any point of the installation arrangement, for example, directly in the area of a socket to which a consumer is connected, are detected. Shutdowns of a consumer can then, for example, by deliberately switching off only the socket to which the consumer is connected, while the rest of the installation arrangement intact continues to be supplied with electrical energy. The display / control unit 1 can also be physically completely separated from the remaining components and separated to be ordered. It is possible, for example, to design and / or arrange these together with the controller for an optionally existing domestic engineering system. In an installation arrangement according to the invention can be completely dispensed with in a further step to a distribution and / or control box in the conventional sense, since the switching devices 3, in particular the circuit breaker, and / or the measuring / evaluation units 2 in the circuit network or in the installation arrangement can be arranged distributed, whereby a central display / control unit 1 obtain a complete overview of the electrical requirements in an electrical circuit arrangement and can better control errors, as already described, only directly the faulty load is taken from the network.

Due to the central control and data acquisition within the electrical installation arrangement, a display / control unit 1 according to the invention also gains a comprehensive overview of the electrical and other physical processes within the electrical installation arrangement. For example, it may be possible to prematurely recognize impending errors, e.g. the fault current or the temperature in a range continuously or steadily rising, can be beaten before exceeding the tripping limits alarm and notified a service technician. As a result, the safety in an electrical circuit arrangement can be increased. In addition, switching devices 3 can be prevented from switching off when the display / control unit recognizes that it is a known, only temporary source of error, such as the startup of a machine.

In known electrical installation arrangements, which allow a partial monitoring of the electrical processes within such, usually a PC for monitoring the system is provided. Such a PC must, in order to be able to fully fulfill the tasks assigned to it, be constantly switched on. Although this is not a problem for large industrial plants, a home or apartment encounters the need for a constantly turned on computer to monitor the installation arrangement to quite legitimate rejection, especially since there should be households without a computer. In an electrical installation arrangement according to the invention, it is provided that the display / control unit 1 monitors and controls the installation arrangement, without having to switch on a PC constantly and to be connected to the circuit arrangement. An electrical installation arrangement according to the invention comprises at least one display / control unit 1 with a second interface 7 designed as an active radio interface for data exchange with a user terminal 4. This makes it possible to transmit data to a user terminal 4, such as a PC 42, a mobile phone 41, a PDA (eg Palm) or the like, to transmit, but for the function and safety of the electrical installation assembly of this user terminal 4 is not fully necessary. By means of the user terminal 4, a user not present in the area of the display / control unit 1, for example a maintenance and / or control technician, but also a house occupant, can be informed of the status or an imminent error of the electrical installation arrangement. As a result, an electrician can be contacted directly if a mistake is made. This electrician could then be on site before the error occurs or shortly thereafter with the right spare parts, and would not have to search for a long error, since he was previously informed by the display / control unit 1 about the error.

By means of the display / control unit 1 can preferably also be controlled intervene in the electrical installation arrangement, in particular by means of the user terminal 4. Thus it can be provided, the electrical installation arrangement or at least individual switching devices 3 by the AnzeigeVSteuereinheit 1 or by a command via a user terminal 4 to turn on or turn on.

Overall, this can be achieved with low Schaltgeräteaufwand, as well as low cabling a good and safe monitoring of the circuit, whereby the security of the circuitry and the people is increased in their environment, and the false alarms can be minimized, creating such a protected circuit a has high active time. Such, separated from the switching devices 3 display / control unit 1 can also be integrated into a control unit for a home automation system.

As already explained, the display control unit 1, the measurement / evaluation unit 2 and the switching device 3 each have at least one first interface 6 designed as an active radio interface. For data transmission within the electrical installation arrangement, each data transmission protocol and / or each frequency band or each radio-technical channel can be provided. It is preferably provided that the first interface 6 operates on a part of an ISM frequency band, in particular in the range of 433 MHz, 868 MHz, 915 MHz and / or 2.4 GHz.

Any data transmission protocol can be provided, wherein both the application of digital and analog transmission and / or modulation methods can be provided. In particular, it can be provided that the display / control unit 1, the measurement / evaluation unit 2 and the switching device 3 means for channel coding, preferably for convolutional coding, in particular trellis, Viterbi, Reed Solomon and / or turbo coding, and / or Modulation, in particular FSK, 2-FSK, 4-FSK, ASK, BPSK, GFSK, PSK and / or QPSK modulation include, whereby a particularly secure and error-free data transmission can be achieved within this security-relevant application. However, linear block codes or other coding methods may also be provided. Further, multiplexing techniques such as TDMA may be provided to better utilize the existing frequency band. The display / control unit 1 has a second interface 7, designed as an active radio interface, for exchanging data with a user terminal 4. It is preferably provided that the second interface 7 is provided for transmitting and receiving data, which is in accordance with a substantially standardized data transmission protocol coded, in particular Bluetooth, GSM, UMTS, WLAN and / or ZIGBEE. Thereby, a particularly simple adaptation of the transmitted data to the user terminals 4 is possible by the data are already encoded in a protocol for which the user terminal 4 in question is designed anyway. The many possibilities that arise or offer the data transfer between the display / control unit 1 and the user terminal 4, in which also other components, such as routers, transmitters and receivers of telecom providers, and / or the like., Are used can be illustrated by the cloud 9 in Fig. 1, which is intended to illustrate the sum of various data transmission methods.

It is particularly preferably provided that the first and / or the second interface 6, 7 are designed as a full-duplex radio interface. As a result, a particularly secure data transmission and circuit arrangement can be achieved, since even while a component is transmitting data, it is also capable of receiving data such as a trigger signal 81.

Furthermore, a so-called handshake method can be provided in which a component sends data until it receives an acknowledgment of receipt of another component. This can ensure that the data sent also arrive. It can be provided, for example, that a switching device 3 in the event of non-arrival of such Acknowledgment of receipt after a certain number of attempts, as can be assumed that a fault in the installation arrangement.

In embodiments of a switching device 3 according to the invention, as described above, and in Fig. 4 shown particularly preferred, in which the switching device 3 comprises a measuring / evaluation units 2, which when a third limit of the physical quantity is exceeded, a trigger signal 81 to the trip unit 33rd transmitted, which triggers the switching mechanism 32), it can be provided that this third limit value, which may coincide with the second limit value, is changed by a first control signal 80 sent by the display / control unit 1. As a result, for example, the tripping limit value of the switching device 3 can be temporarily changed, in particular increased. For example, when the display / control unit 1 recognizes, by the incoming measurements and switch position signals, that a load is turned on which causes, for example, an overcurrent on the supply line, or a fault current, such as a large electric motor or a welder during start-up which loads the lines in the further operation, however, only in the range of permissible limits, the display / control unit 1, which can automatically detect the switching on of this consumer by a previous calibration or a learning phase, the trip limit, therefore the third limit adjust for just this period of startup of the consumer to the expected load, so that the consumer without causing a turn on the supply can start up. After a certain time, the third limit value can then be reduced back to the original value. If this is then still exceeded, it can be assumed that a fault in the system, and the switching device 3 is turned off by the display / control unit 1 and / or the measurement / evaluation unit 2. If the switching device 3 is operatively connected to a reclosing device 5, by the display / control unit 1, a reclosing signal 85 may be sent to the reclosing device 5, which may also include a first interface 6, and by the reclosing signal received 85, the recloser 5 may be caused to close the switch contacts 32 of the switching device 3. As a result, a disconnected switching device 3 can be switched on again from a central location. Furthermore, it can be provided that the instantaneous value of the physical variable, the first or second information signal, and / or the respective instantaneous position of the switching contacts 31 is displayed on a display means 12 of the display / control unit 1.

Further embodiments according to the invention have only a part of the features described, wherein each feature combination, in particular also of various described embodiments, can be provided.
