Maintenance system and method for maintaining a gate device

A maintenance system for a gate device, the maintenance system comprising:

• a controller which comprises,
• a motor control unit which is configured to actuate a drive apparatus for driving a gate member, and
• a non-volatile memory which is configured to store gate data, the gate data being retrievable from the non-volatile memory;
• an ambient temperature sensor which is arranged in a region of the drive apparatus, the ambient temperature sensor being configured to detect an ambient temperature and to continuously transmit the detected ambient temperature to the non-volatile memory of the controller;
• at least one temperature sensor which is arranged in a region of the drive apparatus, the at least one temperature sensor being configured to continuously transmit a detected temperature as further gate data to the non-volatile memory of the controller;
• and
• an evaluation unit which is configured to create a temperature curve for the ambient temperature sensor and for each of the at least one temperature sensor over a preset operating cycle,
• wherein,
• a comparison of the temperature curves allows a conclusion to be drawn of a need for maintenance of the gate device, and
• a steadily rising temperature curve of the at least one temperature sensor over several consecutive operating cycles of the gate device, which steadily rising temperature curve excludes a seasonal influence via the ambient temperature sensor, indicates a possible defect in the gate device which is proactively fixable prior to a spontaneous functional failure of the gate device.
