[0003] Mobile measuring system

[0004] Technical field

[0005] The present invention relates to a mobile measuring system, a higher-level system comprising the mobile measuring system, a method for operating the mobile measuring system, a computer program, and a computer-readable medium. The present invention relates in particular to a mobile measuring system (with associated higher-level system, method, computer program, and computer-readable medium) in which electricity measurement data (in particular concerning electricity consumption at a location of the mobile measuring system) are supplemented with a timestamp and a georeference of the location of the mobile measuring system, wherein the timestamp represents the time of receipt of the electricity measurement data at the mobile measuring system.

[0006] Related state of the art

[0007] The processing of temporary construction power meters involves a significant amount of manual data entry, as the systems and processes of the metering point operator are not designed for metering devices without a fixed installation location. Currently, considerable time elapses before temporary construction power meters are registered in energy management systems, and manual entries are a frequent source of errors (e.g., incorrect installation location or time). Due to the delay in recording the installation data, the energy generated or the electricity consumed is not yet accounted for by the supplier and must first be considered in the loss balancing group of the distribution network operator (DNO).

[0008] Another challenge is inaccurate annual consumption forecasts due to highly variable consumption patterns, which, in total, lead to problems for the distribution network operator (DNO) across multiple metering devices. Actual consumption from mobile meters is usually impossible to predict due to the short installation periods, as the necessary measurements are only available after the meter has been removed.

[0009] DE 10 2013 109 258 A1 discloses a mobile measuring system for temporary installation in a spatially limited application area, wherein a communication module is arranged on or in a housing, which includes a mobile communication transmit / receive unit, a control unit and at least one LEW Verteilnetz GmbH 30A-169 202

[0010] - 2 -

[0011] The system includes a data transmission interface for establishing a data communication connection. The field devices to be monitored consist of sensors for acquiring measurement data in the application area. The communication module is configured to transmit the sensor data to a sensor data recording database on the application's central processing unit and to store it there. However, the sensor data is not supplemented with georeferencing or timestamps.

[0012] German patent DE 10 2017 109 035 A1 discloses a construction site box for recording the amount of electricity or water consumed. The construction site box comprises a meter that records the amount of electricity and water consumed and transmits this data to a communication module, and a communication module that transmits the amount consumed, the meter's location, and the date and time to a connected computer. However, the correlation between the amount consumed, the meter's location, and the date / time is too vague – the electricity measurement data (particularly concerning electricity consumption at a location of the mobile measuring system) is not supplemented with a timestamp and a georeference of the mobile measuring system's location, where the timestamp represents the time the electricity measurement data was received by the mobile measuring system.

[0013] DE 10 2021 103 128 Al, DE 10 2012 102 742 Al, DE 10 2008 058 264 Al and DE 10 2016 110 175 Al disclose mobile construction site boxes with associated measurement and distribution methods. However, the recorded consumption data is not supplemented by georeferencing or timestamps.

[0014] Summary of the invention

[0015] The invention is therefore based on the objective of providing an improved mobile measuring system that solves at least some of the problems described above.

[0016] This problem is solved by the present invention as described in the independent claims. Preferred embodiments are described in the dependent claims. LEW Verteilnetz GmbH 30A-169 202

[0018] Without limiting the generality of the invention, it can be summarized as follows. The mobile, georeferenced measuring device consists of a measuring device (e.g., mME = modern measuring device). The measurement data is transmitted via an interface of the measuring device (e.g., via probe according to IEC 62056-21 or rear interface according to DIN VDE 0603-5). A cellular modem (SARA-R410M-02B) and a GPS module (SAM-M8Q) are used to determine the position. A cellular modem with multi-SIM capability is used for data transmission. Additionally, a battery (e.g., lithium polymer) is used to bridge short-term interruptions. The components are installed as an external device in a DIN rail enclosure on a circuit board with terminal blocks. The software runs on a microcontroller (Arm® Cortex®-M0 32-bit processor SAMD21) with a crypto chip (Microchip® ECC508). The mobile, georeferenced measuring device consists of a measuring device (e.g.,mME (modern metering device) provides calibrated measurement data for energy management purposes (billing and balancing). Via an interface of the metering device (e.g., via probe according to IEC 62056-21 or rear interface according to DIN VDE 0603-5), the measurement data is georeferenced at regular intervals (depending on the metering technology) in a technical module (external as a separate device or integrated into a meter) and temporarily stored with the time of receipt (time at which the measured value reaches the module). At a configurable interval (e.g., daily, weekly, monthly, or every 15 minutes if required), the temporarily stored measured value is transmitted to the operator of the metering point. A mobile modem is used for data transmission. The technical module is also equipped with a battery (e.g.,The device is equipped with a lithium polymer battery, allowing the last stored meter reading to be transmitted to the metering point operator after the device has been removed. To prevent brief power outages from causing the metering device to be removed or deactivated at the metering point operator's location, a timeout for power restoration can be configured. The necessary technical components are installed externally in a DIN rail enclosure, enabling efficient installation and removal. These components can also be integrated into the metering direction. The transmitted data is collected and processed before being used in the energy management systems. This processing involves assigning the measured values ​​to the metering points within the systems based on their spatial proximity.

[0051] Execute services, functions, and steps. This applies in particular to the design of an automated procedure for operating the mobile measurement system.

[0052] Fig. 1 shows a higher-level system 1 comprising a mobile measuring system 10 according to the invention, a measurement data source 20, and a processing device 40. The mobile measuring system is connected to the internet 30 via a wired interface 105, 105b or a wireless interface 104, 104a, 105, 105a. The wireless interface 104, 104a can be implemented via a cellular interface (e.g., a cellular modem such as the SARA-R410M-02B) with multi-SIM (e.g., via 2G / GSM, 3G / UMTS, 4G / LTE, 5G / NR, 6G, or via related or successor radio access technologies) or, for example, via WLAN / WiFi 105, 105a. The wired interface 105, 105b can be implemented as a LAN / Ethernet connection.

[0053] The mobile measuring system 10 comprises a measuring device 101, which is configured to receive electricity measurement data MD, indicating electricity consumption at a location of the mobile measuring system 10, from the measurement data source 20. The measuring device 101 is preferably a probe (e.g., according to IEC 62056-21) or a rear interface (e.g., according to DIN VDE 0603-5). The measurement data source 20 is preferably a modern measuring device (mmE) or an intelligent metering system (iMSys), also known as a smart meter, and is preferably configured to determine the electricity consumption at the location. The mmE / iMSys preferably provides calibrated measurement data for energy management purposes (e.g., billing and balancing).

[0054] The mobile measuring system 10 further comprises a supplementary device 102, 103, which is set up to supplement the electricity measurement data MD with a timestamp ZS and a georeference GR of the location, wherein the timestamp ZS represents the time of receipt of the electricity measurement data MD (e.g. time at which a measurement reaches the receiving device 101) at the mobile measuring system 10.

[0055] The georeference GR is not limited in its format. Cartesian plane or two-dimensional coordinates (e.g., with x and y axes) are possible, as is a specification in latitude and longitude, such as GPS coordinates. These plane or two-dimensional coordinates can be supplemented with an elevation, e.g., above sea level or in relation to the so-called "street level" (e.g., a z-axis). LEW Verteilnetz GmbH 30A-169 202

[0056] - 9 - will be - this is advantageous, for example, for large construction sites in high-rise buildings with multiple acceptance points or building owners (if, for example, several mobile measuring systems 10 are used at one location).

[0057] The timestamp ZS is also not limited in its format. A complete time, e.g., with (or without) date in plain text, is just as possible as an (internal) system time, which is defined, for example, only in relation to a (higher-level) system. Such a time or system time can be specified by the mobile measuring system 10 using an internal timer or can be adopted from an external source. An incremental value, which is incremented (or possibly decremented) in program cycles, is also possible.

[0058] The supplementary device 102, 103 preferably comprises a central processing unit 102 configured to supplement the measurement data MD with the timestamp ZS (represented in the drawings by "+[ZS]"). The central processing unit 102 can be a CPU (e.g., a microcontroller such as an Arm® Cortex®-M0 32-bit SAMD21 processor or an Arduino) and can also include a crypto chip 1022 (e.g., a Microchip® ECC508) for cryptographic purposes. The crypto chip 1022 can, for example, encrypt the supplemented measurement data MD to ensure its confidentiality and / or digitally sign the supplemented measurement data MD (e.g., using a hash value) to ensure its integrity.

[0059] The supplementary equipment 102, 103 preferably further comprises a georeferencing device 103, which is configured to supplement the measurement data MD with the georeference GR (represented in the drawings by "+[GR]"). The georeferencing device 103 can be a GPS module (e.g., SAM-M8Q).

[0060] The mobile measuring system 10 further comprises a storage device 1021, which is configured to temporarily store the supplementary electricity measurement data MD. The storage device can be part of the central processing unit 102 and is preferably a non-volatile storage device that retains data (in particular the supplementary measurement data MD) even when the mobile measuring system is de-energized. LEW Verteilnetz GmbH 30A-169 202

[0061] - 10 -

[0062] The mobile measuring system 10 further comprises a transmitting device 104, 105, which is configured to send the supplemented current measurement data to the external processing device 40 (e.g., via the wired interface 105b or wireless interface 104a, 105a described above). In other words, the transmitted data are preferably collected and prepared for further processing in the energy management systems before being processed. This preparation preferably involves assigning the measured values ​​to the measuring points in the systems based on their spatial proximity.

[0063] As can be seen particularly in Fig. 2A, the measuring device 101 is preferably further configured to receive the supplementary current measurement data MD once per first time interval IV1 from the measurement data source 20, the storage device 1021 is preferably further configured to form and temporarily store a set SA of supplementary current measurement data from the supplementary current measurement data MD, and the transmitting device 104, 105 is further configured to send the set SA of supplementary current measurement data once per second time interval IV2 to the external processing device 40, wherein the second time interval IV2 is longer than the first time interval IV1. The first time interval IV1 is preferably a few seconds and depends, for example, on the measurement technology used. The second time interval IV2 is preferably configurable and is, for example, 15 minutes, one day, one week, or one month.

[0064] As can be seen particularly in Fig. 2B, as soon as the mobile measuring system is de-energized (see the crossed-out lightning symbol in Fig. 2B), the transmitting device 104, 105 is preferably further configured to send the set of SA supplemented current measurement data to the external processing device 40 only after the mobile measuring system 10 has been de-energized for a predetermined time T. The predetermined time T is preferably 12 hours. In other words, to prevent short-term power interruptions from leading to the removal / deactivation of the measuring device at the operator's site, a timeout T for re-energizing the system can be configured. This eliminates the need for a fault check by a human operator.

[0065] The mobile measuring system 10 preferably comprises a power storage device 106, which is configured to supply the mobile measuring system 10 with power after the mobile measuring system has been de-energized. The power storage device 106 is preferably a battery, in particular preferably a lithium-polymer battery. LEW Verteilnetz GmbH 30A-169 202

[0066] - 11 -

[0067] A battery that bridges short-term interruptions. In this way, after the mobile measuring system 10 is removed, the last temporarily stored meter reading can be transmitted to the operator of the metering point. In this case, the storage device 1021 can also be designed as a volatile storage device, which is buffered by the power storage device 106 and thus retains the supplementary power measurement data MD when the mobile measuring system 10 cannot rely on an external power supply (not shown).

[0068] In one embodiment, the processing unit 40 is preferably a backend, and the transmitting unit 104, 105 is preferably configured to send the supplementary measurement data MD together with a system identifier to the backend in order to automatically register the mobile measuring system 10 with the backend. This results in an automatic assignment of the installation location / site (e.g., construction site or fairground, such as a Ferris wheel or bumper cars) of the mobile measuring system 10, so that no human operator needs to check where the mobile measuring system 10 has been connected.

[0069] The mobile measuring system can also include a housing 100. Housing 100 is, for example, a DIN rail housing in which components 101, 102, 103, 104, and 106 are installed individually or as a single integrated circuit / measuring device on a circuit board, e.g., with PCB terminals. This allows for efficient installation and removal.

[0070] Fig. 2A shows a method for operating the mobile measuring system according to one embodiment, and Fig. 2B shows the method for operating the mobile measuring system according to a variant of the embodiment.

[0071] Figures 2A and 2B show a method for operating a mobile measuring system 10. The method comprises the steps: Receiving S1, by the measuring device 101 (described above), from the data source 20 (described above), electricity measurement data MD, indicating electricity consumption at a location of the mobile measuring system 10; Supplementing S2, S2a, S2b, by the supplementing device 102, 103 (described above), the electricity measurement data MD with a timestamp ZS and a georeference GR of the location, where the timestamp ZS represents the time of receipt of the electricity measurement data at the mobile measuring system 10; Temporarily storing S3, by the storage device 1021 (described above), the supplemented electricity measurement data MD; and transmitting S4, LEW Verteilnetz GmbH 30A-169 202

[0072] - 12 - by the (above-described) transmitting device 104, 105, the supplementary current measurement data MD to the (above-described) external processing device 40.

[0073] In particular, Fig. 2A shows how the receive step S1 preferably receives the augmented current measurement data MD once per first time interval IV1 from the measurement data source 20, the intermediate storage step S3 preferably forms and temporarily stores a set SA of augmented current measurement data from the augmented current measurement data MD, and the transmit step S4 preferably sends the set SA of augmented current measurement data once per second time interval IV2 to the external processing device 40, wherein the second time interval IV2 is longer than the first time interval IV1. As an example, Fig. 2A shows twice how three data packets MD (during three intervals IV1) are augmented in step S1 with the timestamp ZS in step S2a and with the georeference GR in step S2b, and are summarized / accumulated in step S4 into the set SA (once in interval IV2).The number of three data packets MD per set is purely exemplary - given that the first time interval IV1 can be a few seconds (e.g. 10 seconds), but the second time interval IV2 can be from 15 minutes to a month long, a large number of packets (from about one hundred packets to several thousand packets) can be combined / accumulated into a set SA of packets.

[0074] In particular Fig. 2B shows how - as soon as the mobile measuring system is switched off (see crossed-out lightning symbol in Fig. 2B) - the transmission step S4 preferably sends the set SA supplemented current measurement data to the external processing device 40 only when the mobile measuring system 10 has been switched off for longer than a predetermined time T.

[0075] All the designs, aspects, advantages and implementations described under the device aspect in Fig. 1 also apply to the process aspect in Figures 2A and 2B.

[0076] Referring back to Fig. 1, the central processing unit 102 functions as a processor, and the storage device 1021 functions as a computer-readable medium that stores a computer program CP. The computer program CP, in turn, stores code segments which, when executed on the processor 102 of the mobile measuring system 10, cause the mobile measuring system 10 to perform all steps of the procedure described above.
