For the sliding touch line power supply system, the main electric component is the carbon brush supported by the collector. In the actual use process, due to many reasons, such as the spark scarring of the contact surface of the carbon brush blade of the sliding contact line, the wear limit of the carbon brush blade is not found and replaced in time, the deformation of the sliding contact line itself and the steel structure support, the carbon brush blade of the collector will be removed from the guide of the sliding contact line. If this situation is not found in time, it will further cause damage to the collector and a large area of sliding contact line damage, making the power equipment can not continue to work, which has brought great economic losses to the port.

The intelligent collector testing system (IECMS) can always monitor the status of the carbon brush of the collector, reduce the labor cost of daily inspection of the sliding contact power supply system, greatly reduce the occurrence of the collector or sliding contact line damage caused by various reasons, and bring the most direct and indirect economic benefits to the user. The system hardware increase is less, the installation is convenient, and the maintenance cost is low.
