Abstract
The invention provides an electric locomotive key interlocking alarm device. Each electrical switch is in mechanical linkage with a corresponding locomotive key. One end of each electrical switch is connected with the +5 V direct current power end of a microprocessor, and the other end of the electrical switch is connected with the signal input end of the microprocessor. The output end of the microprocessor is connected with an alarm unit and an execution mechanism. Fault combination states of various locomotive keys are written into the microprocessor. The microprocessor receives level signals of all the electrical switches. When the level signal combination of all the electrical switches accords with a certain locomotive key fault combination state, the alarm unit is driven to give an alarm, and the execution mechanism is driven to execute a protection action. Through logical judgment of the mechanical interlocking electrical switches, the locomotive key fault combination states can be found accurately in time, the alarm unit is driven to give the alarm, the protection action is executed, and equipment burning loss and personal injury and death accidents caused by human factors of operation staff are completely and reliably avoided.
Description
Technical field
The present invention relates to a kind of electric locomotive key linkage alarm device, belongs to locomotive manufacturing technical field.
Background technology
Carry out for ease of the safe and smooth of work such as electric locomotive rising bow, power supply, ground connection and maintenance, to machine in prior art
The relevant device of car is provided with key switch：Blue key, for brake cabinet rising bow position, the main ground connection position of high-voltage board；Yellow key, is used for
High-voltage board working position；Green key, for each cabinet door switch lock.The mechanical chain relation of these keys is as follows.
During blue key controller rising bow state：Yellow key is in working position, and key locker has been extracted now green key and cannot have been pulled out
Go out；Yellow key on key locker is extracted, the Huang key working position twisting of insertion high-voltage board is simultaneously made main earthed switch to isolated bit,
Blue key is extracted, and is inserted in twisting at brake cabinet rising bow valve lock, open rising bow pipe-line system.
During the main ground connection of blue key controller：Yellow key can be extracted, and be inserted on key locker, and green key can be opened after arbitrarily extracting
Close each regulator cubicle.
However, as blue key can be inserted simultaneously in brake cabinet rising bow and high-voltage board two kinds of working positions of main ground connection simultaneously
Work；Yellow key can control the main ground connection of high-voltage board and the green key of key locker respectively；Green key can random cabinet door, so as to can
Problems with can be caused：
1., in the case where having blue key in brake cabinet rising bow position and locomotive rising bow being touched net, operator hold other one blue
Key inserts the main ground connection position of high-voltage board and main ground connection is worked, and causes contact net short circuit even equipment scaling loss or casualties；
2., in locomotive rising bow and high-voltage board Huang key is in the case of the working position, operator hold the yellow key of a locomotive
Spoon, insertion key locker twist and extract green key, can arbitrarily open all kinds of high and low pressure cabinet doors, now easily cause casualties thing
Therefore generation；
3. when locomotive rising bow is used, the electric cabinet door of locomotive high and low pressure can be opened with green key, this situation easily occurs personnel
Casualty accident.
The content of the invention
The purpose of the present invention is exactly the deficiency for overcoming above-mentioned prior art, there is provided a kind of chain dress of reporting to the police of electric locomotive key
Put.
The object of the present invention is achieved like this：A kind of electric locomotive key linkage alarm device, by each electric switch, micro-
Processor, alarm and actuator composition, it is characterised in that each electric switch respectively with corresponding locomotive Key machine
Tool links ,+5V the DC power supply terminals of a termination microprocessor of each electric switch, the signal input of another termination microprocessor
The failure assembled state of various kinds of vehicles key is write micro- place by end, the outfan device taking alarm of microprocessor and actuator
Reason device, microprocessor receive the level signal of each electric switch, when level signal combination and a certain locomotive key of each electric switch
When failure assembled state is consistent, alarm equipment alarm, actuator is driven to perform protection act.
Technical scheme, by the logical judgment of electric interlock, can find locomotive key failure accurately and in time
Assembled state, and drive warning and perform protection act, reliably avoid that the anthropic factor of operator causes completely set
The generation of standby scaling loss and personnel casualty accidentses.
Description of the drawings
Electric locomotive key linkage alarm device schematic diagrams of the Fig. 1 for the embodiment of the present invention.
Fig. 2 represents intention for several locomotive failure assembled state logical judgment of the embodiment of the present invention.
Every locomotive of electric locomotive only have 1 blue key, 1 yellow key, 7 green key, when locomotive operation, green in overhauling
Key quantity is to send audio alert more than 7, and this process is overlapped judgement by software.
Specific embodiment
To make purpose, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention, rather than the embodiment of whole.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Referring to accompanying drawing 1, the electric locomotive key linkage alarm device of the present embodiment, by each electric switch, microprocessor, report
Alert device and actuator composition.Each electric switch is linked with corresponding locomotive key mechanical respectively, one end of each electric switch
Connect+5V the DC power supply terminals of microprocessor, another termination microprocessor signals input.The outfan of microprocessor is taking alarm
Device, and pass through locomotive microcomputer central processing unit controls main circuit breaker.
Accompanying drawing 2 gives locomotive failure assembled state logical judgment and represents example." 1 " in table represents "On" state, " 0 " table
Show "Off" state, " X " represents free position.By the failure assembled state write microprocessor of various kinds of vehicles key.Microprocessor connects
The level signal of each electric switch is received, when level signal combination and a certain locomotive key failure assembled state phase of each electric switch
Fu Shi, drives alarm equipment alarm, actuator to perform protection act.
Finally it should be noted that：Above example only to illustrate technical scheme, rather than a limitation；Although
With reference to the foregoing embodiments the present invention has been described in detail, it will be understood by those within the art that：Which still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
