Abstract
The invention discloses a kind of rail vehicle emergency ventilation control method and system, control air-conditioner controller in emergency inverter failure will not repeat to inverter send allows start order, when inverter work will not repeat to inverter transmission enabling signal, the fault-signal of emergency inverter or working state signal are fed back into air-conditioner controller, effectively extend the service life of auxiliary reclay.
Description
Technical field
The present invention relates to rail vehicle emergency ventilation control field, particularly a kind of rail vehicle emergency ventilation control method
And system.
Background technology
Emergency ventilation instruction on city rail vehicle is to urgent inversion when air-conditioner controller can't detect AC380V power supplys
Device sends enabling signal, whether does not detect the malfunction of emergency inverter in itself, does not also consider whether inverter has connect
Worked by the permission enabling signal sent by air-conditioner controller.Being sent in air-conditioner controller allows emergency inverter to start
Instruction after, whether emergency inverter does not feed back receives startup order, cause that air-conditioner controller repeats always to urgent
Inverter send allow enabling signal, also without emergency inverter whether the feedback of failure, cause in emergency inverter failure
When air-conditioner controller be not aware that emergency inverter failure, also repeating to send enabling signal to emergency inverter,
Enabling signal is sent by the contact closure of auxiliary reclay, and the life-span of auxiliary reclay is calculated by the closure number of contact, is repeated
Send the service life that signal directly affects auxiliary reclay.
The content of the invention
The present invention is intended to provide a kind of rail vehicle emergency ventilation control method and system, in emergency inverter failure not
Can repeat to inverter send allow start order, when inverter work will not repeat to inverter send start believe
Number, extend the service life of auxiliary reclay.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of rail vehicle emergency ventilation control
Method, including implemented below process：When air-conditioner controller can't detect AC380V power supplys, air-conditioner set shuts down, delay
T1S air-conditioner controllers drive adhesive emergency ventilation contactor, then postpone T2S is sent to inverter allows enabling signal, afterwards inversion
Device, which starts, starts working；After inverter startup, the working condition of inverter or malfunction are fed back into air-conditioner controller；It is empty
Controller is adjusted by controlling internal passive normally opened contact transmission enabling signal to inverter, when passive normally opened contact closes,
Inverter receives enabling signal, starts to start, and inverter stops output when passive normally opened contact disconnects；When inverter has DC110V
Power input and when receiving the enabling signal that air-conditioner controller is sent, controls a pair of passive normally-closed contacts of inverter internal to break
Open, feedback operation signal to air-conditioner controller, this is remained closed to passive normally-closed contact during other situations；When inverter has
DC110V power inputs and when receiving the enabling signal that air-conditioner controller is sent, inverter starts self-test, and self-test is by rear, inversion
A pair inside device passive normally opened contacts closures, feedback normal signal to air-conditioner controller, when self-test not by or inverter send out
During raw failure, the passive normally opened contact of the inverter internal disconnects, feedback inverter failure.
In the present invention, T1=10s；T2=2s.Vehicle main power source power-off time is short to be possible to lead for maloperation, overlong time
Cause not blow inside guest room, the comfortableness inside guest room declines, T1And T2Setting, can prevent inside guest room under comfortableness
Drop.
Correspondingly, present invention also offers a kind of rail vehicle emergency ventilation control system, it includes：
Air-conditioner controller, for when can't detect AC380V power supplys, controlling air-conditioner set to shut down, and in delay T1After s
Adhesive emergency ventilation contactor is driven, then postpones T2S is sent to inverter allows enabling signal, after inverter startup, receives
The working condition or malfunction of inverter, by controlling internal passive normally opened contact transmission enabling signal to inverter,
And when inverter there are DC110V power inputs and receives enabling signal, control a pair of passive normally-closed contacts of inverter internal
Disconnect, receive feedback operation signal；When inverter there are DC110V power inputs and receives enabling signal, inverter internal is controlled
A pair of passive normally opened contacts closures, receive the normal signal of inverter fed, inverter self-test not by or inverter send out
During raw failure, the passive normally opened contact of inverter internal is controlled to disconnect, feedback inverter failure；
Inverter, for after enabling signal is received, feedback operation state or malfunction to be to air-conditioner controller, in air-conditioning
Passive normally opened contact inside controller starts to start when closing, and is having DC110V power inputs and is receiving air-conditioner controller hair
During the enabling signal gone out, feedback operation signal to air-conditioner controller keeps during other situations passive normally-closed touching for its internal a pair
Point remains closed；When there are DC110V power inputs and receiving the enabling signal that air-conditioner controller is sent, start self-test, self-test is led to
Later, feed back normal signal to air-conditioner controller, when self-test not by or when breaking down, to air-conditioner controller feedback failure letter
Breath.
Compared with prior art, the advantageous effect of present invention is that：The controllable air-conditioner controller of the present invention is urgent
Being sent to inverter of will not being repeated during fault of converter allow to start order, will not be repeatedly when inverter work to inversion
Device sends enabling signal, and the fault-signal of emergency inverter or working state signal are fed back into air-conditioner controller, avoids weight
Enabling signal is sent to emergency inverter again, can effectively extend the service life of auxiliary reclay.
Embodiment
When air-conditioner controller can't detect AC380V power supplys, air-conditioner set will shut down（Disconnect all attracting states
Contactor）, delay 10s air-conditioner controller driving adhesive emergency ventilation contactors, then postpone on 2s driving air-conditioner controllers
Auxiliary reclay, being sent by the normally opened contact of auxiliary reclay to inverter allows enabling signal, and inverter startup is opened afterwards
Beginning work., will be anti-by the working condition of inverter or malfunction by status signal and fault-signal after inverter startup
Feed air-conditioner controller.Air-conditioner controller sends enabling signal to inverter by the passive normally opened contact inside control, when tactile
During point closure, inverter receives enabling signal, starts to start, and inverter stops output when contact disconnects.Working state signal by
A pair of passive normally-closed contacts of inverter internal provide, when inverter has DC110V power inputs and receives air-conditioner controller hair
During the enabling signal gone out, the contact is controlled to disconnect, feedback " work " signal is to air-conditioner controller, contact holding during other situations
Closure.Fault-signal is provided by a pair of passive normally opened contacts of inverter internal, when inverter has DC110V power inputs and receipts
During the enabling signal sent to air-conditioner controller, inverter starts self-test, and self-test is by rear, the contact closure, feeds back " normal "
Signal to air-conditioner controller, when self-test not by or inverter break down when, the contact disconnects, feedback inverter failure.
Implement such scheme in the Line 1 increasing purchase project of Shanghai, found in running in emergency inverter failure not
Can repeat to inverter send allow start order, when inverter work will not repeat to inverter send start believe
Number, avoid and repeatedly send enabling signal to emergency inverter, it was demonstrated that the validity of the inventive method.
