The commission, configuration, and maintenance of water pumps for groundwater management in a strip mining area can only be done on-site. Thanks to an Industrial App on an Android tablet the service technicians are able to complete their tasks in a fraction of the previously needed time.
Hundreds of independently working water pumps are deployed in the strip mining area. The commission, configuration and maintenance are done on-site. Service workers travel to the individual water pumps by car and connect to the pump's PLC using a proprietary handheld device. The service tasks detailing the configuration parameters are supplied on paper. The typical amount of time for servicing one pump is 30 minutes. The service works are carried out regardless of the weather conditions.
The necessary service work is being hampered by media breaks leading to insufficient data quality and by the complicated user interface of the heandheld device. The device's display is hard to read in bad lighting conditions.
Each morning the service technician fetches his tablet from the charging station. His work assignments have already been transferred to the device and he is good to go.
The Industrial App always points the service technician towards the current water pump from his list of work assignments. However, the actual route planning in the difficult terrain of the strip mining area calls for the knowledge of an experienced worker. Man and machine form a powerful unit.
Thanks to the optimization of the Industrial App the work steps can be done with a few taps. All necessary data from the PLC and the details of the work assignment are available. After the work is done the work protocols are transfered to the adjacent systems and new work assignments are supplied.
The next day can come.
An Industrial App on an Android tablet is provided to facilitate the commission, configuration and maintenance of water pumps on-site. The user navigation and the design has been developed in close collaboration with the service technicians and is tailored to the necessary work steps.
The data is transmitted directly via Bluetooth, no additional infrastructure is required. Android saves the ID of the PLC automatically during the first connect to speed up subsequent connection attempts. There is enough storage capacity on modern devices to save the data of all water pumps in the strip mining area.
The exchange of work assignments is done automatically using Microsoft Excel™ files thus servicing the interfaces of all relevant adjacent systems.
The deployment of the Industrial Apps and their updates is done via a company-owned app store. Only authorized personnel is able to access the Industrial Apps for the deployment, configuration, and maintenance of the water pumps. Thanks to the flexible access rights management the company-owned app store supports the user life cycle optimally. Workers are granted access to the Industrial App only when the completion of the work assignment demands it.
