The accompanying drawing in example is applied, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described implementation
Example only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
The every other embodiment that technical staff is obtained under the premise of creative work is not made, should all belong to protection of the present invention
Scope.
Fig. 1 is refer to, a kind of supervising device of air supply system drier provided in an embodiment of the present invention includes：
Obtain and export the drier of the drier status signal, draining valve status signal and power state signal of drier
Monitoring module 1；
The main control module 2 being connected with the drier monitoring module 1, the main control module 2 receives the drier state
Signal, the draining valve status signal and the power state signal, and judging the drier status signal, the draining
In valve status signal and the power state signal at least one for it is abnormal when, send air compressor machine start and stop instruction；
It is being connected with the main control module 2, when receiving air compressor machine start and stop instruction, control air compressor machine is out of service
Air compressor machine control module 3.
The supervising device of air supply system drier provided by the present invention, including drier monitoring module 1, main control module 2
With air compressor machine control module 3.The drier monitoring module 1 in real time the monitoring drier state of drier, draining valve state and
Power supply status, obtains and exports the drier status signal, draining valve status signal and power state signal of drier；Master control mould
Block 2 is connected with drier monitoring module 1, receives the drier status signal, draining valve status signal and power state signal,
And judge whether the drier state, draining valve state and power supply status of drier are normal according to the status signal, judging
In drier status signal, draining valve status signal and power state signal at least one for it is abnormal when, show drier work
Make state and occur abnormal, then main control module 2 sends air compressor machine start and stop instruction, air compressor machine control module 3 is opened receiving air compressor machine
Control air compressor machine out of service during stop instruction, so as to control air supply system and its drier out of service.
Therefore, the supervising device of the air supply system drier described in the present embodiment is realized to drier work in air supply system
Make the real-time monitoring of state, in time air supply system can be controlled to stop when monitoring drier working condition exception or being stopped
Only run, to avoid because drier working condition exception or the compressed air for causing air supply system to provide that is stopped are unsatisfactory for wanting
Seek and have influence on the normal work of locomotive braking system.

Operation.
Therefore when drier state occurs abnormal, control air compressor machine out of service by air compressor machine control module 3, simultaneously
Air compressor machine control module 3 controls drier out of service by drier monitoring module 1, so to the start-up and shut-down control of drier
Reliability is higher.
In the present embodiment, the supervising device also includes attention device, is monitoring drier state, the draining valve of drier
When at least one appearance in state or power supply status is abnormal, the air compressor machine start and stop that attention device is sent according to main control module 2 are instructed
Alarm signal is sent, to point out crew member.
Supervising device described in the present embodiment also includes display module 4, and display module 4 is connected with the main control module 2, uses
Show in the drier status signal, the draining valve status signal, the power state signal for exporting drier monitoring module
Show.Further, the display module 4 may also display the instruction drier state, draining valve state or power supply status exception
Information warning, when drier state, draining valve state or power supply status occur abnormal, display module shows information warning,
So as to which crew member can learn that drier is abnormal by the prompting of display module, and know which is according to specific information warning
Part is broken down, to take maintenance measures in time.
The display module 4 includes display screen, and display screen described in the present embodiment is locomotive display screen, such crew member
Monitor the state of drier in drier, draining valve and power supply in real time by locomotive display screen, grasp in real time and monitoring drier
Middle drier state, draining valve state and power supply status.When crew member is had found according to alarm signal or by locomotive display screen
When drier exception occurs or is stopped, crew member can take maintenance in time according to the dependent failure information of drier
Measure.
Therefore, the supervising device of the air supply system drier described in the present embodiment obtains drying by drier monitoring module
The status signal of drier, draining valve and power supply in device, by main control module realize drier working condition occur it is abnormal or
Control air supply system and drier out of service when being stopped, crew member can grasp and monitor in real time dry by display module
The running status of dry device, enables crew member to be taken measures in time when drier occurs abnormal, so as to ensure air supply system
The compressed air dried, cleaned can be provided for brakes, the normal operation of locomotive braking system is ensured.
The supervising device of air supply system drier provided by the present invention is described in detail above.It is used herein
