Description

1. Technical field

[0001] The invention relates to a mobile measuring station for acquiring, processing, storing, and transmitting environmental parameters in buildings, transport containers, and technical systems. The measuring station combines DECT-ULE sensors, multi-channel measurement, local evaluation, data logging, and WLAN and LTE connectivity for remote transmission of measured values ​​and diagnostic data. It is particularly suitable for building analysis, freight monitoring, transport logistics, mobile inspections, and temporary measurement setups. 2. State of the art

[0002] Mobile measurement systems exist in the form of data loggers, WLAN sensor boxes, or wired measuring cases. However, these systems have significant limitations: • lack of DECT-ULE integration, • no multi-channel sensor platform, • no self-contained threshold logic, • No LTE connection for mobile use, • no combination of local storage, web interface and remote transmission, • No way to detect multiple DECT-ULE sensors simultaneously.

[0003] A mobile DECT-ULE measuring station with LTE router that evaluates multiple sensors simultaneously, stores measured values ​​locally and is accessible via web interface and mobile network is not known in the state of the art. 3. Object of the invention

[0004] The object of the invention is to provide a self-sufficient, mobile multi-channel measuring station that: • can detect multiple DECT-ULE sensors simultaneously, • Stores measured values ​​locally in the data logger, • Thresholds are monitored autonomously, • can trigger events without central infrastructure, • communicates via LTE mobile network, • provides a web interface for configuration and download, • is particularly suitable for mobile, self-sufficient and stationary applications. 4. Solution to the task

[0005] The task is solved by a multifunctional, multi-channel smart home sensor platform that includes at least the following features: • an LTE router module for mobile data transmission, • a DECT-ULE radio module for wireless communication with a router, • a WLAN module for providing a local web interface and for data transmission within the local network, • at least one temperature, air quality and humidity sensor per data logger, • an internal calculation of dew point, absolute humidity and enthalpy, • a multi-channel measurement architecture, • an integrated data logger for storing time-based measurement series, • a local threshold logic that works without a router or cloud and triggers events via DECT-ULE, • a web interface for configuring and downloading the saved data, • An energy-efficient firmware for long-term measurement. 5. Implementation Examples 5.1 Hardware Setup

[0006] The measuring station platform includes: • Microcontroller or embedded system • DECT-ULE radio module • LTE router module • Flash memory for data loggers • Web server module • Battery or power adapter • Antennas for LTE and DECT-ULE • Status indicators (LEDs) 5.2 Measurement functions

[0007] The measuring station platform can simultaneously detect multiple DECT-ULE sensors, including: • Temperature • Relative humidity • Dew point (calculated) • Absolute humidity (calculated) • Enthalpy (calculated) • VOC / CO2 / Pressure (if sensor is present) 5.3 Data logger

[0008] The data logger stores measured values ​​with timestamps, even over extended periods. The data can be accessed via: • Web interface (local) • LTE connection (remote) can be accessed and saved as a download for further processing. 5.4 Local Threshold Logic

[0009] Threshold values ​​can be defined for each measurement channel. If these values ​​are exceeded or not reached, the platform can automatically: • send a DECT-ULE event, • trigger an internal action • change an internal status, • Control an LED, relay or other device (optional) • Send a message via email or SMS over LTE 5.5 Web interface

[0010] The web interface is provided via WLAN and enables: • Sensor configuration • Setting the threshold values • Download the measurement data • Firmware information • Diagnostic functions • Status indicator for LTE, WLAN and DECT-ULE connection • Device updates 5.6 Mobile Use

[0011] The measuring station is designed for mobile and self-sufficient use: • Transport case or robust housing • self-sufficient energy supply • Automatic network connection via LTE • Automatic sensor detection via DECT-ULE • Provision of a dedicated local Wi-Fi environment 6. Advantages of the invention

[0012] The invention offers the following advantages: • Cloud-independent: All functions run completely locally in the router / home network, without external servers or cloud services. • Local integration: The platform uses the existing router as a central instance for DECT-ULE and WLAN, without additional gateways or proprietary control centers. • Multi-channel capable: Multiple sensors can be read and processed simultaneously. • High building penetration: DECT-ULE radio technology enables reliable communication even over greater distances and through multiple walls. • Autonomous and self-sufficient threshold logic: Events are triggered locally in the device without the need for external services or cloud automation. • Integrated data logger: Long-term measurements can be performed, displayed, read out and stored locally without external infrastructure. • Web interface via WLAN: Configuration and data retrieval are done via the local network, without the need for an app or internet connection. • Energy efficient: The firmware is optimized for continuous operation and enables long runtimes. • Expandable: The platform can be extended with additional sensors or functions via firmware updates. 7.
