Problems solved by technology

Since the control is achieved through the on-off of the relay contacts, planned maintenance and daily maintenance are required to ensure reliable contact of the relay contacts, and the relay has shortcomings such as short life, large size, and slow conversion speed; in addition, the relay The combination control circuit has multiple relays, the wiring between the relays in the combination is complicated, the construction is inconvenient, and it is difficult to find faults.
With the development of technology, a control circuit that replaces the gravity relay with a small elastic relay has appeared, and modularization has been realized. This method solves the shortcomings of the traditional control circuit, such as large volume, complicated wiring, and inconvenient construction. However, due to the use of relays, the inherent defects of short life, slow conversion speed, and daily maintenance have not been resolved.
Obviously, these defects restrict the improvement of railway operation safety and transportation capacity and increase the workload of maintenance personnel
