  • Testing and adaptation to the operating conditions of a communication system to capture weather-technical readings and to switch off the electrical power supply


In the scientific plan, a readily available measuring and switching system in a fail-safe technique has been developed into an operational system and has been authorized for ignition protection type self-security and has been tested in underground use.

The report consists of two main parts. In the first part, the development of hardware and software for the existing prototype with regard to explosion protection and function security are described. Moreover, the connection of the steering unit with a data transfer system, and the development of a data terminal recording data of interest underground are discussed. In the second part, there is a report on the first underground test operation of the complete installation in the shaft plant Heinrich-Robert. .
