Mobile Data Acquistion

Using mobile data capture process-relevant data is localfreely recorded and made available. This data comes from a back-end system, z. B. an ERP or inventory management system, more rarely of a CRM system. The data is displayed by means of mobile devices and acquired. Depending on the purpose solutions can be equipped with different data acquisition devices, such as a bar code scanner or RFID technology. This business processes are optimized so that time for information gathering and recording can be saved.

…

So there are now for example, mobile solutions for care services and hospitals. The nurses access to the data from a hospital information system via a laptop or PDA.

Mobile solutions can be used for various processes:

  • In the industrial sector, this may be for example, processes in the warehouse and production, but also to application areas "away from home" such as sales or field service or in the area of ​​extradition.
  • Commercially barcode readers and PDAs supported in particular the areas of storage of goods, goods dispatch and inventory as well as the dynamic storage. MDE devices make it possible to create products without having to walk to any free storage spaces, of scanning items and storage location and save the assignment in the system. This allows the bearing to use more efficient because each storage space can be used for each item. In principle, for use of mobile data recording all processes theoretically conceivable in which there are strong advantages result from the fact that employees can localfreely access the data of a system.
  • With the help of mobile solutions for care services and hospitals the nurses access to the data from a hospital information system via MDE device.

In principle, for use of mobile data recording theoretically all processes, in which there are strong advantages that result as the employee can localfreely access the data of a system, are conceivable.

When choosing an MDE device several distinguishing characteristics play a significant role.

From the type of application, the different requirements towards the robustness of the MDE device, are:

  • Protection against dust and water: This is indicated by the IP protection. aitronic provides MDE devices up to IP65.
  • Fall Protection: Industrial standard instrument are i.d.R. protected against multiple fall on concrete from 1 m.
  • Temperature range: devices for extreme operating temperatures can be used from -20° C to + 50° C.

As is frequently performed with a mobile data acquisition device a whole working day, the ergonomics is an important property:

  • Pistol grip: A device with pistol grip is useful for applications where intensive barcodes are scanned (for example, inventory).
  • Weight: The lightest mobile data acquisition device (LogiScan-1100 without grip) weighs 200 g, an industry-compatible device (LogiScan-600) for example, 450 g.
  • Size: Small mobile data acquisition devices (e.g. LogiScan-1100) can be plugged into the lab coat pocket.
  • Keyboard: Depending on the version, the mobile data acquisition device feature touch keyboard (Android) or numeric or alphanumeric hardware keyboards. Even for Android-based obile data acquisition devices that are standard operated with touch keyboard, there are versions with numeric or alphanumeric hardware keypad.
  • Display size: The display of the devices of series LogiScan-600/800/1100 have screen-size of about 2 inches with a resolution of 128 x 64 pixels. Android-based units of series LogiScan-15xx have a screen diagonal of about 4 inches with a resolution of 800 x 600 pixels.

The operating system is the basis for developing own applications:

  • Proprietary operating system: Mobile data acquisition devices of series LogiScan-600/800/1100 are operated with the aitronic-own operating system DeOS. The design of the user interface is character-oriented for the most part.
  • Android: Mobile data acquisition devices of series LogiScan-15xx operate under Android. Android offers convenient programming with Android Studio in Java and provides access to many hardware elements that are supported by Android. A clear design of complex graphical user interfaces, as we know from modern operating systems, is a matter of course.

The data entry can be caused by various hardware components:

  • Barcode Reader: Are usually always integrated. There are models with laser (1D) or CCD scanner (2D). How do 1D and 2D barcode scanners differ?
  • RFID Reader: Different transponders with operating frequencies 125/134 kHz (LF) and 13.56 MHz (HF) can be read and written.
  • Keyboard: The Android-based mobile data acquisition devices of series LogiScan-15xx come standard with a touch keyboard, but are also available with numeric or alphanumeric hardware keypad. Devices of series LogiScan-600/800/1100 have numeric keypads. Numeric keypads are due to the larger keys better use and users familiar with its T9 input from mobile phones. However, where a lot of text to be entered, alphanumeric keyboards are preferable.
  • Touchscreen: The Android-based mobile data acquisition devices provide basically a color display with touch screen.
  • Camera: The Android-based mobile data acquisition devices can be optionally equipped with a CMOS camera. This can be used to read 1D / 2D bar codes and for capturing images (for example, signatures).

The type of data transfer depends on the application:

  • Offline: For non-time-critical applications, the collection/storage of data in the mobile data acquisition device is sufficient. At a later time then the data are transmitted to the host computer via a docking station/cradle (also called a batch method).
  • Online: If the recorded should be available for further processing as soon as possible or the mobile data acquisition device will receive a response from the host computer after sending the collected data, the data has to be send to the host immediately after the acquisition by radio data transmission (DECT, Bluetooth, WLAN, GSM / GPRS).
