    The invention relates to a method for wireless reading and writing of parameters of electrical voltage-supplied devices, in particular welders or inverters, wherein stored in a device memory of the electrical device device parameters sent via a transceiver and device parameters are received via the transceiver and written to the device memory.
    Furthermore, the invention relates to a device for wireless reading and writing of parameters of electrical voltage-supplied devices, in particular welding devices or inverters, with a transceiver for transmitting and receiving the stored in a device memory of the electrical device device parameters.
    The invention relates in principle to a variety of electrical voltage-supplied or network-connected devices, but in particular to welding equipment or inverters, as they are used in particular in photovoltaic systems. Conventional such electrical devices can not be operated in a de-energized state, so if there is no connection to the power supply, but also not changed or influenced in their configuration.
    For example, it has become known from WO 2013/114188 A1 to supply a welding device with a mobile terminal, for example a mobile phone, tablet or the like, via Bluetooth or Firewire with specific data or to query device parameters in this way. However, it is imperative that both the welding device and the mobile terminal have an appropriate power supply. In the unavailable state of the welder communication is not possible and thus a reading or writing the device parameters of the welder is not possible. Before a query of the data or a change in the configuration, it is therefore necessary to connect the welding machine to the power supply.
    The object of the present invention is therefore to provide an above-mentioned method and apparatus for wireless reading and writing of parameters of electrical voltage-powered devices, by which even in the dead
    State of the electrical device, a query of the device parameters or changing the device parameters is enabled. Disadvantages of known methods and devices should be avoided or at least reduced.
    The object of the invention is achieved in terms of the method in that an energy storage is charged via the power supply of the electrical device, and the power supply of the electrical device is monitored by a controller, and depending on the power supply of the electrical device, a transfer of the device parameters is performed. Depending on the voltage supply, the present method makes it possible to communicate with the electrical device in order to read out device parameters or to load device parameters into the device. This allows a number of configuration options for electrical devices even in the off state or without mains supply by means of corresponding mobile terminals, such. Smartphones, tablets, PCs or the like. According to the invention, therefore, the power supply of the electrical device is monitored and depending on the power supply or the status of the power supply relevant device parameters are transferred.
    Preferably, in the case of interruption of the power supply, the device parameters are written from the device memory into a nonvolatile memory connected to the transceiver, and written in the case of connection of the power supply stored in the nonvolatile memory device parameters in the device memory of the electrical device. Thus, the present method also enables communication with the electrical device in the de-energized state in order to read device parameters or to load device parameters into the device. Preferably, in the case of interruption of the power supply of the electrical device, the relevant device parameters are written from the device memory in a non-volatile memory, from which they can be transmitted wirelessly via a transceiver to a mobile terminal or via which specific device parameters can be received and written to the non-volatile memory , The method according to the invention makes it possible to read out the device parameters even in the state without mains supply or to write changed device parameters into the electrical device, without this necessarily having to be arranged on the mains supply.
    Advantageously, the device parameters are received or transmitted via short-range radio. In this case, a wireless connection in the 2.4 GHz frequency band, as used in the Bluetooth standard, is particularly suitable. In particular, the wireless technology Bluetooth Low Energy or Bluetooth LE, with the devices can be networked in an environment of about ten meters, is due to the very low power consumption particularly for the implementation of the subject method. In addition, many mobile terminals, such as e.g. Smartphones or tablets equipped with communication via Bluetooth.
    If, during connected power supply of the electrical device, the device parameters are written automatically from the device memory to volatile memory at predetermined intervals and the device parameters are automatically written from volatile memory to non-volatile memory when the power supply is interrupted, it can be ensured that at the time of interruption of the power supply of the electrical device or disconnection of the power cord always the current device parameters are stored in non-volatile memory. The interval or the time intervals can be adapted to the respective electrical device and the usual frequency of the change of the device parameters accordingly and in principle be arbitrary from microseconds range to minutes or longer intervals.
    According to a further feature of the invention, operating data of the electrical device is transmitted to the non-volatile memory. Depending on the electrical powered device, various important operating data, such as e.g. Operating time, operating temperature, operating voltage and much more, are sent to the non-volatile memory and read out there via the transceiver to document the operation of the electrical device can. Such a measure can also be of great relevance for warranty claims.
    Furthermore, data from internal sensors or external sensors can be forwarded to the controller. By means of such sensors, data which may be of relevance for the operation of the electrical device can be detected and read out via the transceiver if necessary, and from this important insights for the operation of the electrical device can be obtained.
    For example, temperature values from temperature sensors can be forwarded to the controller. In this way, the operating temperature of the corresponding electrical device or the temperature of the process carried out with the electrical device, such as welding process, can be documented and if certain limits are exceeded, for example, a forced shutdown or a warning to the mobile terminal of the user.
    When acceleration values from acceleration sensors are forwarded to the controller, detection of movements of the electrical device, for example for the purpose of anti-theft protection, or an impermissible manipulation of the electrical device can take place via such acceleration sensors which are arranged at suitable locations of the electrical device or associated components Device are documented. The data of the acceleration sensors are transmitted via the transceiver to a suitable mobile terminal, where they can be forwarded to appropriate locations and there, for example, lead to the triggering of an alarm.
    It is also important if position and / or position data of position and / or position sensors are forwarded to the controller. The position and / or position data of the electrical device may be useful on the one hand to prevent theft, but also help in larger production halls or the like. Find the device easier. For example, a user with his mobile terminal, such as his smartphone, send out a corresponding position and / or location request and receive the appropriate data, which he needs to locate the electrical device.
    Finally, wind data from wind sensors can be forwarded to the controller. Such usually external wind sensors may be of relevance for welding in the open air in order to prevent a welding process when exceeding certain upper limits of the wind, where a safe environment of the weld with inert gas could no longer be guaranteed and thus the quality of welding would suffer. Apart from the above-mentioned sensors, many other applications are also conceivable.
    We solve the object of the invention also by an above-mentioned device for wireless reading and writing parameters of electrical voltage-powered devices in which a rechargeable via the power supply of the electrical device energy storage is provided, further a controller for monitoring the power supply of the electrical device is provided which Controller is designed to transfer depending on the monitored power supply of the electrical device or the status of the power supply device parameters accordingly. The device is relatively small and inexpensive to produce and can either be installed directly in the relevant electrical device or subsequently connected to this. For the achievable advantages, reference is made to the above description of the method for wireless reading and writing of device parameters.
    Advantageously, the controller is designed to write the device parameters in a non-volatile memory in case of interruption of the power supply, and in the case of the connection of the power supply automatically store the device parameters stored in the non-volatile memory to the device memory.
    The transceiver is preferably formed by a short-range radio transceiver. As already mentioned above, the radio technology Bluetooth, in particular Bluetooth LE, is particularly suitable for this purpose.
    According to a further feature of the invention, a volatile buffer is provided, which is connectable to the device memory and the non-volatile memory, so that during connected power supply of the electrical device, the device parameters at predetermined intervals automatically writable from the device memory in the volatile buffer and the power supply parameters when the device is interrupted automatically writable from volatile memory to non-volatile memory. In this way, it is always ensured that the corresponding device parameters are available after disconnecting the electrical device from the power supply in the non-volatile memory by continuously the device parameters are buffered from the device memory in a volatile buffer and detected upon detection of disconnection of the power supply this in the volatile buffer Data still be transferred to the non-volatile memory.
    Advantageously, an interface for the transmission of operating data of the electrical device to the non-volatile memory is provided. As already mentioned above, operating data of the electrical device can be read out for documentation purposes.
    As already mentioned above, internal sensors or external sensors can be connected to the controller, which results in further interesting possibilities when operating the electrical device.
    As such internal or external sensors, for example, temperature sensors, acceleration sensors, position and / or position sensors, wind sensors, etc. into consideration.
    The energy store is preferably formed by an accumulator, in particular a lithium ion accumulator. Depending on the embodiment of the transceiver and controller of the device, usually very small accumulators suffice for temporarily storing the electrical energy, which ensures operation of the device even when the power cord of the electrical device is disconnected. During the power supply of the electrical device, the accumulator is usually charged via the power supply of the electrical device.
    In addition, capacitors, in particular supercapacitors or super-caps are used as energy storage. Such capacitors may be sufficient in transceivers operating according to the Bluetooth LE standard, for example, to ensure operation of the controller and transceiver of the device.
    The invention will be explained in more detail with reference to the accompanying figures, which show exemplary embodiments. Show in it
    1 shows a block diagram of an electrical device with a device according to the invention for the wireless reading and writing of device parameters Pi,
    FIG. 2 is a flowchart of a method for wirelessly reading and writing device parameters of the subject type; FIG. and
    3 is a block diagram of a welder having an apparatus for wirelessly reading and writing device parameters according to the invention and having various sensors connected to the controller of the device.
    FIG. 1 shows a schematic block diagram of an electrical device 1 with a device 2 according to the invention for wireless reading and writing of device parameters P ±. The device parameters Pi and possibly operating data Bi of the electrical device 1 are usually stored in a corresponding device memory 8. According to the invention, a device 2 for wireless reading and writing of the device parameters Pi of the electrical device 1 is provided and, for example, integrated in the electrical device 1 or connected thereto via corresponding interfaces. The device 2 contains a transceiver 5 for transmitting and receiving the device parameters Pi and an energy store 6 and a controller 4 for monitoring the power supply 9 of the electrical device 1 and for managing the data transfers from the device memory 8 to the device 2 or the nonvolatile memory 3 contained therein The energy store 6 can be formed by an accumulator 17, in particular a lithium ion accumulator, or a capacitor 18, in particular a supercapacitor or super cap. The controller 4 of the device 2 monitors the
    Power supply 9 of the electrical device 1. If an interruption of the power supply 9 is detected, the controller 4 causes the device 2 that the device parameters Pi are written from the device memory 8 in the nonvolatile memory 3. Likewise, operating data B ± of the electrical device 1 can be transmitted via an interface 7 to the non-volatile memory 3. Now it is possible, even when switched off and disconnected from the network state of the electrical device 1 stored in the nonvolatile memory 3 of the device 2 device parameters Pi and also operating data Bi via the transceiver 5 to a mobile terminal, such as a smartphone or a tablet to transmit whereby the user of the electrical appliance 1 can obtain important information without activation thereof. Conversely, even when switched off and disconnected from the network state of the electrical device 1 data from the mobile device 19, for example via Bluetooth LE, to the transceiver 5 and subsequently to the non-volatile memory 3 are transmitted, from where they at startup of the electrical device 1 or connection of the power plug with the power supply via the controller 4 to the device memory 8 are transmitted. In this way, an update of the device parameters Pi of the electrical device 1 can also be made in the disconnected and disconnected from the mains state. As already mentioned, the transceiver 5 is preferably formed by a near-range radio transceiver, in particular a Bluetooth LE transceiver. Short-range radio is understood here to mean that data can be transmitted essentially within sight of the electrical device 1. The visibility is for example in the range of lm up to several hundred meters. In the case of the short-range radio transceivers 5 used, it is important that the data transmission takes place with low power in order to protect the energy store 6.
    In order to be able to write all device parameters Pi and operating data B into the nonvolatile memory 3 with as little energy as possible, a volatile buffer memory 10 may be provided (this may be contained in the electrical device 1 or in the device 2) in which At the relevant device parameters Pi and operating data B ± be written and transferred in the event of interruption of the power supply 9 in the non-volatile memory 3.
    By additional internal sensors 11, which may be located both in the device 2 itself or in the electrical device 1, as well as external sensors 12, which are connected to the controller 4 of the device 2, important additional information can be obtained, which also in the off and disconnected from the mains state of the electrical device 1 can be read by a mobile terminal 19. The sensors 11, 12 are supplied by the power supply 6 of the device 2.
    2 shows a flow diagram of a method for wireless reading and writing of device parameters Ρ ± of an electrical, voltage-supplied device 1. After the start of the method according to the invention (block 100), the power supply 9 of the electrical device 1 is monitored according to query 101 Interruption of the power supply detected, is jumped back in the process flow back and checked again if an interruption has occurred. If an interruption of the power supply is detected in accordance with query 101, the device parameter Pi, possibly operating data Bi, of the electrical device 1 from the device memory 8 into the nonvolatile memory 3 is written according to process block 102. This device parameter Pi stored in the nonvolatile memory 3 and possibly operating data Bi can be read out via the transceiver 5 or new device parameters Pi can be written to the nonvolatile memory 3 via the transceiver 5. Next, in the process sequence according to FIG. 2, the power supply 9 is again monitored (block 103) and, if the power supply 9 is still interrupted, jumped back again in the course of the process. If the power supply 9 is again ensured, the data of the nonvolatile memory 3 is written to the device memory 8 of the electrical device 1 according to block 104. If new data is now stored in the nonvolatile memory 3 of the electrical device 1 when the electrical device 1 is switched off or disconnected from the mains Written device 2, the renewed plugging the electrical device 1 to the supply in the device memory 8 are taken, where they are available immediately.
    In the course of the process, for example, another query 105 is made as to whether to continue with the method or to terminate the method. If necessary, jumping back to the start or, according to block 106, terminating the method. Optionally, according to block 107, a write of the data of the device memory 8 to a volatile memory 10 may be made and this repeated in the loop of the interrogation 101 and the block 107 until an interruption of the power supply is detected and further jumped to block 102.
    Finally, FIG. 3 shows a schematic block diagram of a welding device as an electrical, voltage-supplied device 1 with a device 2 according to the invention for wireless reading and writing of device parameters Pi and various internal and external sensors 11, 12, which are connected to the controller 4 of the device 2.
    As internal sensors 11, for example position and / or position sensors 15 come into question, as external sensors 12, for example, temperature sensors 13, acceleration sensors 14 or wind sensors 16, which are all wired or wirelessly connected to the controller 4 of the device 2. Operating parameters Bi can also be read out in the switched-off or disconnected state of the welding device via a mobile terminal 19, or new device parameters Pi can be recorded in the device 1. For example, the mobile terminal can contact a corresponding server 20 on the Internet 21 and from there download certain welding parameters for a specific welding task at most at a cost and then load them into the welding machine without the welding device having to be connected to the network for this purpose.
    In addition to such query and configuration tasks, the device 2 may also serve to protect against theft, to determine the status of the device, to externally visualize welding parameters, to connect to a smart welding helmet, or to communicate with other external devices. In addition to a configuration of the electrical device 1 at delivery, without a plugging and unpacking of the electrical device 1 is required, this also facilitates the storage management, allows registration between welder and welder or facilitates reading the device parameters Pi. Furthermore, certain services can be offered on the Internet and the acquired parameters or data can be imported into the electrical device 1 via the mobile terminal 19.
