| Abstract: | The no-contact modification program for the electric control system of SS4 modified electric locomotive is put forward. The technical principle of distributed control by use of logic control unit (LCU) is expounded. Also discussed is the communication between the two LCUs. The operations in last six months show that the modification program is practical, rational and efficient. |
