Makeshift valve 2 is installed, the output end of makeshift valve 2 leads to total wind blocking pipe, the makeshift valve 2 of relay valve on total wind blocking pipe between valve
A control terminal by from the total wind in valve end blocking control system, another control terminal by normally closed solenoid valve B through main reservoir pipe wind pressure control
System；Normally open solenoid valve D is provided on pipe between valve and relay valve；In relay valve end pipe with train pipe it
Between be provided with normally closed solenoid valve E.When remote state emergency braking, normally open solenoid valve D is closed after being powered, and cutting is from valve to relaying
It is managed in valve, while connecting in relay valve end after normally closed solenoid valve E energization and managing and train pipe access；Normally closed solenoid valve B
Connect access of total wind to the total wind blocking pipe in relay valve end, total wind intercepter valve (IV) closing；Electronic vent valve C is opened, and train pipe is urgent
Air draft, locomotive emergency braking.
Pressure transmitter is installed on braking earthen pipe, is used for regenerative braking cylinder pressure, when single valve braking remote signal issues 3
Second or more after, (the control signal that should theoretically issue lower than driver, but be examined when if feedback signal is lower than department's machine control signal
Consider engineering component and inevitably detect and control error, and the stability to guarantee system, feedback signal is lower than control
Between signal 5-10%), signal receives microcomputer and issues instruction emergency braking automatically.
