One moment train-line does not have latch voltage transmission direction, can then execute S102 at this time.
When direction signal locking direction, then it can determine that train line voltage passes according to the concrete form of direction signal
Defeated direction, so as to adjust the output end level of logic control element corresponding in train, i.e. execution S103.
S102: according to the level signal of the two of current logic control unit input terminals, the signal shape of adjustment direction signal
Formula.
For ease of description, in embodiments of the present invention, can define high level is useful signal, and low level is invalid letter
Number.The processing mode of each logic control element is similar, in the present invention is implemented, with all logic control lists of a train
Explanation is unfolded for any one logic control element, that is, current logic control unit in member.
When the direction signal of current logic control unit is invalid signals, then it can come according to the level signal of input terminal true
The direction of settled preceding logic control element train-line, so that it is determined that voltage direction of transfer in each logic control element out.
In order to realize the double-direction control to train, in logic control element all the way input/output signal with another way
Input/output signal is in parallel, in order to avoid this two-way input/output terminal constitutes closed loop, needs to be believed according to the level of input terminal
Number, the level of output end is adjusted in time.
The partial structure diagram of logic control element as shown in connection with fig. 3, including two input terminals, for the ease of area
Point, IN1 can be referred to as to first input end, IN2 is referred to as the second input terminal, correspondingly, OUT1 corresponding with IN1 is referred to as first
Output end, OUT2 corresponding with IN2 are referred to as second output terminal.
It, in embodiments of the present invention, can be by the electricity between logic control element each in train for the ease of subsequent introduction
The sequence of pressure direction of transfer from left to right is referred to as positive direction, correspondingly, the voltage between logic control element each in train is passed
It passs the sequence of direction from right to left and is referred to as opposite direction.
In the concrete realization, it can be determined that whether the level signal of first input end is high level and the second input terminal
Whether level signal is low level.
When the level signal that the level signal of first input end is high level and the second input terminal is low level, then say
Each logic control element is successively to transmit voltage signal according to sequence from left to right in bright train, at this time can be by direction signal
It is adjusted to positive useful signal.
When the level signal that the level signal of first input end is low level either the second input terminal is high level, then
Illustrate that the voltage signal of each logic control element in train is not transmitted according to forward direction, can further judge the first input at this time
Whether it is high level that whether the level signal at end is the level signal of low level and the second input terminal.
When the level signal that the level signal of first input end is low level and the second input terminal is high level, then illustrate
The voltage signal of each logic control element is transmitted according to opposite direction in train, and direction signal can be adjusted to reversed effective at this time
Signal.
When the level signal of first input end and the level signal of the second input terminal are low level or are high level
When, then low level is set by the level of the first output end corresponding with first input end in current logic control unit, incite somebody to action
The level of second output terminal corresponding with the second input terminal is set as low level.
S103: according to the control signal in direction type and current logic control unit belonging to direction signal, adjustment with
The level of the corresponding output end of input terminal.
It may be positive useful signal is also likely to be reversed useful signal when direction signal is useful signal.It is different
Direction type, the level set-up mode of output end is different in logic control element.
Specifically, when direction signal is positive useful signal, then according to the level signal of first input end and control
The level signal of the first output end is arranged in signal；And low level is set by second output terminal；When direction signal is reversed effective
When signal, then according to the level signal of the second input terminal and control signal, the level signal of second output terminal is set；And by
One output end is set as low level.
In conjunction with Fig. 3, when IN1 is high level, when current logic control unit can work normally, then controlling signal also is high electricity
Flat i.e. useful signal, first input end IN1 and the first output end OUT1 are in the conductive state at this time, in order to avoid IN1- > OUT1-
> IN2- > OUT2 forms closed circuit, leads to the non-normal working of logic control element, at this time can be by second output terminal OUT2
It is set as low level.Similarly, when IN2 is high level, when current logic control unit can work normally, then it is high for controlling signal also
Level, that is, useful signal, the second input terminal IN2 and second output terminal OUT2 are in the conductive state at this time, in order to avoid IN2- >
OUT2- > IN1- > OUT1 forms closed circuit, leads to the non-normal working of logic control element, at this time can be by the first output end
OUT1 is set as low level.
S104: the level signal of target output is transmitted to the input terminal of next logic control element.
It include multiple logic control elements in a train, logic control list corresponding to the compartment occupied except driver
Member is outside ultimate node, and other logic control elements are required to after determining output end voltage according to voltage transmission direction, to
Next logic control element transmits useful signal.
It include that there are two output end OUT1 and OUT2 such as in conjunction with Fig. 3, in logic control element.Assuming that INI is high level,
OUT1 is high level, and voltage direction of transfer is positive direction at this time, and OUT1 is target output.
It can be seen from above-mentioned technical proposal when the unlocked direction of the direction signal of current logic control unit, then illustrate
Current time prime train-line level is not set up, and current logic control unit is not to next compartment output level.It at this time can basis
The variation of the level signal of two input terminals of current logic control unit, the signal form of adjustment direction signal；Current logic
It, then can be according to the direction type and current logic control list belonging to direction signal when the direction signal locking direction of control unit
Control signal in member adjusts the level of output end corresponding with input terminal, to guarantee the output of current logic control unit
End level matches with direction signal；And the level signal of target output is transmitted to the input of next logic control element
End.Two-way train includes multiple compartments, and each compartment is provided with logic control element, referring to the work of current logic control unit
Make mode, the orderly control to entire two-way train may be implemented.
In view of that in practical applications, can there is the case where level shake, in order to reduce level shake to logic control list
The influence of member, can be set count value.
By taking train forward travel as an example, in the concrete realization, believe according to the level signal and control of first input end
Number, the level signal of the first output end is set；And set can also further judging after low level for second output terminal
Whether one input terminal is low level.
When first input end is high level, then count value is reset；When first input end is low level, then will count
Value plus one, and judge whether the second input terminal is whether low level or count value are greater than or equal to preset threshold.
Either work as first input end when first input end and the second input terminal are low level to be low level and count
Numerical value is greater than or equal to preset threshold, then direction signal is adjusted to invalid signals.
By taking train backward going as an example, in the concrete realization, believe according to the level signal and control of the second input terminal
Number, the level signal of second output terminal is set；And set can also further judging after low level for the first output end
Whether two input terminals are low level.
When the second input terminal is high level, then count value is reset；When the second input terminal is low level, then will count
Value plus one, and judge whether first input end is whether low level or count value are greater than or equal to preset threshold.
When first input end and the second input terminal are low level either when the second input terminal is low level and is counted
Numerical value is greater than or equal to preset threshold, then direction signal is adjusted to invalid signals.
Wherein, preset threshold can be set to 2.When first input end be low level, and count value be greater than or equal to 2
When, then explanation may cause logic control element to the driving mode error in judgement of train, then may be used at this time due to level shake
To set invalid signals for direction signal.
When being provided with count value, correspondingly, by current logic control unit corresponding with first input end
The level of one output end is set as low level, sets low level for the level of second output terminal corresponding with the second input terminal
It also needs to reset count value later, to realize the reset of logic control element.
The erroneous judgement that level shakes bring train driving mode can be effectively reduced by the way that count value is arranged, further
Improve the accuracy and safety of logic control element work.
In conjunction with Fig. 3, level either from IN1- > OUT1 or the direction IN2- > OUT2 is handled by logic control element
Can correctly judge afterwards energization direction and voltage is passed into next logic control element.In practical applications, by
Car room of powering provides electric energy, is successively transmitted downwards by the logic control element in each compartment, is finally transmitted to where driver
Car room.In embodiments of the present invention, each logic control element can be regarded to a node unit as, and can be by driver
The logic control element of place car room is set as ultimate node unit.
Specifically, before the level signal of target output is transmitted to the input terminal of next logic control element also
Can further judge whether current logic control unit is ultimate node unit.
If current logic control unit is not ultimate node unit, the level signal of target output is transmitted to by execution
The step of input terminal of next logic control element.
If current logic control unit is ultimate node unit, without a logic control element transmission level still further below
Signal.
If current logic control unit is ultimate node unit, illustrate that current logic control unit is set to where driver
Car room, understand the executive condition of each logic control element in time for the ease of driver, the level of target output can be believed
Comprehensive judgement result number as train-line level.
When the non-effective signal of the level signal of target output, then it is corresponding to its to illustrate that target output is not received
Input terminal transmission level signal.
Lead to the reason of not receiving level signal, it may be possible to which failure occurs in current logic control unit, it is also possible to
There is failure in the prime node unit of current logic control unit, and the failure for causing level signal to be transmitted can carry out at this time
Warning note.
Wherein, the mode of warning note can there are many, for example, play audio either by display screen show or
It is by indicator light flashing etc..
By using the level signal of target output as the comprehensive judgement of train-line level as a result, can be in order to driver more
Add and get information about whether each logic control element can work normally, and when logic control element goes wrong, can and
When remind driver find and solve the problems, such as, improve the integral working of logic control element.
