The Q walk-by system

There. And gone
Simple, fast and reliable. These three attributes are the most apt description of the
Q walk-by system. Q walk-by makes meter reading as inexpensive as it is easy by using a mobile readout system – just walking by. The meter-reader no longer has to enter the tenant’s flat or office. He can carry out his job on the readout date in the publicly accessible areas of the building – in the case of smaller systems he can even usually receive the data from outside the building. That not only benefits the meter-reader (who no longer has to plan and mount data collectors), but also tenants. The tiresome arrangement of appointments and the tenant’s obligation to be present on readout day are no longer necessary.

How Q walk-by works
The meters transmit consumption data – at short intervals – at the set reading time. The meter-reader only needs his mobile readout system. This consists of a mobile data collector and a Personal Digital Assistant (PDA) or laptop with the corresponding software. The data collector collects the radio telegrams and, after a plausibility check, sends them wirelessly to the PDA/laptop via a Bluetooth interface. The software on the PDA/laptop not only manages the data, it also shows the meter-reader the current progress of the procedure. After having received all data, the meter-reader can then leave the property. Back at his workplace, the meter-reader only has to export the data saved and read them into a billing program, for example.

Mobile data collector
This forms the basis for the mobile remote readout system, receives all consumption values from the meters and transfers them to the PDA/laptop. It is battery operated and, delivered in a transport bag, is protected from adverse weather. The bag enables the meter-reader to operate the PDA or laptop with both hands. The radio protocols of the meters are received fast, reliably and at a high range. The mobile data collector then communicates with the PDA/laptop responsible for data storage via an integrated Bluetooth interface.

PDA/laptop and readout software
The PDA/laptop is at the core of mobile data readout: Its integrated Bluetooth interface forms the bridge to the mobile data collector, and its installed readout software controls and monitors data and interfaces. The extensive import and export functions of the QUNDIS software guarantee optimal adaptation of the system to the existing data processing structure.
