Description
Technical field
The present invention relates to a kind of urban tram operating side automatic switching methods, belong to Electrical key control battery and throw
The urban tram field for entering or cutting off.
Background technique
The reason of tramcar belongs to rail vehicle, is limited by track, tramcar cannot turn, and due to safety concerns
It is unable to backward running again.Therefore, tramcar is runed when running to terminal or midway changes traffic direction for some reason
Hold conversion operation.
Currently, domestic city tramcar does not have operating side auto-conversion function mostly, even if part tramcar has
There is the function, and realized by network, when tramcar network failure enters emergency running mode, which will be complete
Full failure.It will lead to the cumbersome of driver operation in this way, guest room illumination, the interruption of air-conditioning and vehicle entertainment system in the case of carrying,
The drawbacks such as the meaningless increase of electricity piece start-stop time and then influence device lifetime.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of urban tram operating side automatic switching method.In view of network
Influence of the failure to route, the design are realized the automatic conversion of operating side by hardware circuitry completely.
A kind of urban tram operating side automatic switching method, the specific steps are, step 101, when there is 1 operating side quilt
Activation and train remains static down, driver operation operating side switching button, changes end time-delay relay and is activated and starts 300s
Countdown, while operating side conversion indicator light is lit, and driver is prompted currently to carry out operating side conversion work；
Step 102, at this time driver disconnect operating side and activate key, and train all devices maintain the working condition before disconnected key
(if subsystem failure itself itself can be protected), battery contactor maintains work, department by changing end time-delay relay
Machine need to activate another operating side in 300s, and operating side conversion process terminates at this time, while operating side conversion indicator light extinguishes；
If step 103, driver does not activate another operating side in 300s, operating side conversion function will fail.For
The considerations of sub-system is protected, all subsystems with control function will stop working, and only lighting system be maintained to work normally, if
Still without activation operating side in 30s, full column will power-off.If battery voltage is lower than 77V in the conversion process of operating side, train will be straight
It taps into and powers off countdown into 30s；
A kind of urban tram operating side automatic switching method, this method by hardware circuitry realize operating side from turn
It changes, and all devices work normally (except equipment faults itself) in conversion process, the time for reaching setting remains unfulfilled operation
End conversion, all devices stop working, and circuit includes trigger circuit, holding circuit and end circuit composition；
Trigger circuit by the button of Self-resetting tape light, zero speed relay contact, change end time-delay relay form；
Holding circuit is by changing end time-delay relay contact, voltage relay, battery retention time relay and battery
Contactor composition；
Terminate circuit to be made of operating side activation key and its end activation relay.
The hardware circuitry from voltage relay, change end time-delay relay and battery retention time relay superposition with
It uses.
The indicator light (button is included) is lighted by the same contact for changing end time-delay relay.
The voltage relay judges that voltage value lower than setting value, will stop operating side conversion.
The conversion method need to be completed in operating side conversion in 300s, if the subsystem of associated band control function cannot be completed
It will stop working, and only retain lighting system and maintain work 30 again.
Detailed description of the invention
In order to illustrate the embodiments of the present invention more clearly, simple be situated between will be made to attached drawing used in embodiment below
It continues.
Fig. 1 is a kind of urban tram operating side automatic switching method flow chart of the present invention；
Fig. 2 is operating side and the battery control of a kind of urban tram operating side automatic switching method of the present invention
Schematic diagram processed；
Fig. 3 is that a kind of operating side activation control of urban tram operating side automatic switching method of the present invention is former
Reason figure.
Specific embodiment
Understand to make the objectives, technical solutions, and advantages of the present invention clearer, With reference to embodiment and
Attached drawing is described in further details the present invention.Here, exemplary embodiment and its explanation of the invention are for explaining this hair
It is bright.
As shown in Figure 1-3, a kind of urban tram operating side automatic switching method, step 101, when there is 1 operating side
It is activated and train remains static down, driver operation operating side switching button changes end time-delay relay and is activated beginning
300s countdown, while operating side conversion indicator light is lit, and driver is prompted currently to carry out operating side conversion work.
Step 102, at this time driver disconnect operating side and activate key, and train all devices maintain the working condition before disconnected key
(if subsystem failure itself itself can be protected), battery contactor maintains work by changing end time-delay relay.Department
Machine need to activate another operating side in 300s, and operating side conversion process terminates at this time, while operating side conversion indicator light extinguishes.
If step 103, driver does not activate another operating side in 300s, operating side conversion function will fail.For
The considerations of sub-system is protected, all subsystems with control function will stop working, and only lighting system be maintained to work normally, if
Still without activation operating side in 30s, full column will power-off.If battery voltage is lower than 77V in the conversion process of operating side, train will be straight
It taps into and powers off countdown into 30s.
This method is realized the automatic conversion of operating side by hardware circuitry, and all devices normal work (is set in conversion process
Except standby faults itself), the time for reaching setting remains unfulfilled operating side conversion, and all devices stop working, and circuit includes touching
Power Generation Road, holding circuit and end circuit composition；
Trigger circuit by the button of Self-resetting tape light, zero speed relay contact, change end time-delay relay form；
Holding circuit is by changing end time-delay relay contact, voltage relay, battery retention time relay and battery
Contactor composition；
Terminate circuit to be made of operating side activation key and its end activation relay.
The hardware circuitry from voltage relay, change end time-delay relay and battery retention time relay superposition with
It uses.
The indicator light (button is included) is lighted by the same contact for changing end time-delay relay.
The voltage relay judges that voltage value lower than setting value, will stop operating side conversion.
The conversion method need to be completed in operating side conversion in 300s, if the subsystem of associated band control function cannot be completed
It will stop working, and only retain lighting system and maintain work 30 again.
As shown in Fig. 2, the button of Self-resetting tape light is SB-ATCE, zero speed relay contact is KA-0SPEED, changes
End time-delay relay is KT-ATCE, voltage relay KA-BAL, battery retention time relay are KT-BA, battery connects
Tentaculum is KM-BA；
As shown in figure 3, operating side activation key is SA-PS, its end activation relay is KA-CABO, local terminal activates relay
Device is KA-CAB1.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
It should be regarded as protection scope of the present invention.
