When work again, if one of break down, master control borad, which can be made, alarms and points out which breaks down；
Three, to the redundancy determination of speed sensor signal, when there is signal input, master control borad can carry out redundancy to signal and sentence
It is disconnected, because being simple two-way signal, only when the just the same redundancy for just judging this signal of simple two-way signal is good, it otherwise will call the police and mention
Show replacement velocity sensor；
Four, the signal that the master control borad of anti-tug device inputs velocity sensor calculated, analyzed, fault diagnosis；
Five, when mainboard, which carries out fault diagnosis, does not find to occur tugboat phenomenon, anti-tug device enters standby mode；
Six, it when mainboard carries out fault diagnosis discovery, and tugboat phenomenon occurs, controls indoor combined aural and visual alarm and issues first
Buzzing alarm, is become flashing to status indicator lamp along with the wheel of not alleviated braking from normally closed；
Seven, after sound-light alarm 3 times, phonetic alarm directly broadcasts out the respective wheel voice not alleviated to parking brake；
Eight, after control in-house operation personnel listen or see warning message, alarm sound can be cancelled by pressing noise reduction key, at this time
Warning device is not issuing alarm sound, but the status indicator lamp of corresponding alarm wheel pair still flashes, until operator alleviates system
It is dynamic；
Nine, after detecting practical parking braking wheel to being alleviated, status indicator lamp extinguishes, and alarm condition is cancelled；
Ten, alert event can be automatically recorded in host in case checking.
The utility model has the advantages that apparatus of the present invention can sound an alarm in time when monitoring that tugboat phenomenon occurs for electric locomotive, notify
Operator is handled in time；It is not alleviated to solve electric locomotive braked wheel, and motor-car by force in the case where no warning, causes to make
The final damage of driving wheel long-time tugboat operation, influences the problem of locomotive operation safety.Apparatus of the present invention are compact to design, convenient for peace
Dress.
