(5) Inspection with monitoring devices

051-1.gif

With regard to East Japan Railway Company's inspection with monitoring devices, a cab monitoring system was installed in System 209.

The cab seen in the photograph is where the monitoring system is installed. Also shown are the monitored cylinder conditions of each rail car. The cab monitoring system can monitor operation route display, accident data, the VVVF control system, partial onboard inspection for the ATS system, announcing device, air conditioning device control, power and braking command, and reset and release of devices.

3 Future Issues

Lastly, I would like to introduce issues to be solved in the future.

Concerning the rail car, mass production of System 209 has only just started, and many issues remain to be solved. First is the need to produce more completely maintenance- free cars. We anticipate being able to achieve most of our goals for electric parts, but the mechanical parts pose future problems relating to deterioration and durability of the air brake, bogie, pantograph parts, etc. We will do more research on new materials and shapes based on the theory of car and ground facility boundary, and on the new function and structure of the hydraulic brake, etc.

Another issue is the rail car installation of a self-inspection system. I have said that East Japan Railway Company has, for the first time with commuter trains, inspected car functions with a monitoring system. By further improving this onboard functional inspection, we will conserve labor for car functional inspections conducted by railway divisions.
