Mobile maintenance

from Wikipedia, the free encyclopedia

Under Mobile Maintenance (English Mobile Maintenance ) is in the industry a generally maintenance process understood by mobile IT tools ( PDA , Smartphone supported).

Demarcation

The term mobile maintenance does not aim to distinguish maintenance outside the workshop from stationary maintenance. Nor does it refer to the maintenance of mobile objects (e.g. buses, subways, trucks).

History and methods

The idea of ​​mobile maintenance developed with the availability of light, mobile end devices, e.g. B. PDA devices with Windows CE or Windows Mobile . Due to poor user friendliness and lack of robustness, the spread of such systems has only slowly gained acceptance in industry, although interest in the technology has existed for years. The main applications nowadays are to support the order feedback process (feedback in the ERP system when the machine is serviced and ready for use again) and to record counter readings (e.g. operating hours) and working times.

The complete replacement of the paper from the maintenance processes has not yet succeeded, as the PDA systems used primarily are too unergonomic to operate. The illustration of a complex maintenance protocol that consists of several A4 pages is only possible with great effort for the person filling out the form. Therefore the acceptance in the workshops is very low.

Today's mobile maintenance systems work with ERP-supported programs and allow remote maintenance protocols . Control and evaluation are carried out using standardized lists or specialized information modules that can be tailored to the respective purpose. The mobile maintenance systems provide the user with information about predefined parameters in almost real time and can react directly within certain limits.

Outside of the ERP world, modern, cloud-based browser solutions are increasingly coming onto the market. These complementary software solutions consist of an app and a web application. Orders are assigned to employees using conventional smartphones or tablet PCs. The more sophisticated the app, the more technical refinements it contains. Must-haves include features such as:

  • personalized user login
  • Real-time synchronization
  • simple menu structure
  • big icons
  • editable order of tasks
  • full offline operation
  • Functions: checklists and checklists, meter and measured value recording, signature and photo function

Further features of further developed systems are, for example:

  • free configuration of content through intuitive operation (without programming language knowledge)
  • Documentation retrieval
  • Barcode / RFID - identification of machines and buildings
  • continuous logging of all activities
  • Further functions: form-based fault reports, mobile recording of tasks and faults, triggering tasks or e-mail notifications in the event of errors and limit value violations (escalation levels), deactivation of the app if the mobile device is lost

The cloud-based browser solution is used to configure the app menus and usually includes user management, device management, calendar functions, an evaluation module with reporting and a central dashboard for triggering / forwarding tasks and error messages.

advantages

In contrast to the non-IT-supported classic maintenance, the following advantages should be realized:

  • Avoidance of media discontinuity when printing / scanning the maintenance documentation
  • Higher availability of the maintenance objects through faster feedback on the completion of maintenance work
  • More efficient use of employees by assigning work orders without having to return to the workshop
  • Simple billing of services and spare parts
