    Description: The present invention relates to the field of measurement of electrical power characteristics in electrical systems, such as photovoltaic systems. In particular, the present invention relates to a corresponding communication unit and a system comprising such a communication unit and an electrical device having measurement electronics.
    Known systems in this field use an interface, in particular a software interface that allows users to transmit configuration data from a user terminal to dedicated measurement electronics of an electrical device. Such interfaces have several disadvantages, in particular uncomfortable procedures for establishing connections between the user terminal and the measuring electronics. Further, the user terminal may be at risk of being damaged when connected to the electrical device when the electrical device is in an inhospitable environment.
    It is therefore an object of the present invention to improve the transmission of configuration data from a user terminal to dedicated meter electronics.
    According to one aspect of the invention, the above object is achieved by a communication unit according to claim 1. Advantageous embodiments may be configured according to any of claims 1-26.
    The communication unit according to the present invention may be advantageous in many ways. In particular, the communication unit may be designed with a much more robust design than common user terminals such as tablet PCs or laptops. It is possible to conveniently carry out data transmission between the communication unit and the user terminal from the remote site so as to prevent the user terminals from being damaged while being connected to measuring means.
    In particular, since the communication unit of the present invention is detachable from the meter electronics, it may be coupled to the user terminal in an environment different from that where the metering takes place. Thus, the communication unit can be read out or the recorded measurement data can be downloaded to a user terminal while the communication unit is disconnected from the measurement electronics.
    A data logger for processing and / or logging the received measurement data for data logging purposes is provided in accordance with a preferred embodiment of the present invention. Measurement data can therefore be stored, in particular continuously, in a data memory of the communication device. Thus, the communication unit is able to collect data from the measurement electronics, and the acquisition of measurement data is independent of a connection to the user terminal.
    In addition, the configuration data may be uploaded to the communication unit when the communication unit is connected to the user terminal (and possibly disconnected from the measurement electronics). The uploaded configuration data may be further transmitted to the meter electronics when a connection is made between the communication unit and the meter electronics (while the user terminal may be disconnected from the communication unit in this case).
    Suitable coupling means may allow the communication unit to be physically attached to the electrical device and physically removed to couple it to the user terminal elsewhere. The coupling means are preferably lockable and unlockable, the communication unit being detachable from the electrical device in the unlocked state.
    A releasable locking mechanism may comprise any means known per se in the prior art for attaching or locking the communication unit to a dedicated counterpart on the electrical device. It is also possible to provide a lock with a key.
    The actuating means (such as keys) provided in accordance with another preferred embodiment of the present invention are advantageous in that the user does not have to interact with special software to initiate data transmission between the communication unit and the electrical device. For example, the user may preferably start transmitting configuration data from the communication unit to the electrical device or start logging the measurement data without a complicated operation indication. Thus, not even a display needs to be required. In a particularly preferred embodiment, an actuating means provided for this purpose (key) causes a microcontroller to send configuration data to the measuring electronics.
    According to a particularly preferred embodiment of the present invention, the transmitting and receiving unit is formed as an IR unit, wherein received or transmitted signals representing measurement data and / or configuration data are transmitted by infrared light. IR data transmission is particularly advantageous in difficult, for example, corrosion-causing, environments requiring sealed housings.
    The communication with the user terminal may preferably be based on Bluetooth, Wi-Fi, GSM and / or ZigBee standard or the like. This is advantageous because the signal transmission can be performed in the absence of cables. Wired communication connections are also possible according to a further preferred embodiment of the present invention and can at the same time serve as a power supply for charging a battery. Such a communication port is preferably a USB1.0, USB2.0, USB3.0, USB3.1, USB Type-C, or a Firewire communication port or the like.
    It is preferable to integrate both wireless and wired communication ports to increase flexibility.
    In general, each of the embodiments described herein or options mentioned herein may be particularly advantageous depending on the actual application conditions. Furthermore, features of one embodiment may be combined with features of another embodiment as well as functions known per se from the prior art, as far as technically possible and unless stated otherwise.
    The invention and preferred embodiments thereof will now be described in more detail. The accompanying drawings, which are schematic views, serve to better understand the features of the present invention.
    The drawings are schematic and not to scale. Corresponding features are identified by the same corresponding reference numerals in the various drawings.
