Fig. 2 is the implementation flow chart of the vigilant brake control method for train of the embodiment of the present application.Specifically, below
It is further described in conjunction with Fig. 1 and Fig. 2 for above-mentioned implementation steps.Firstly, in step s 110, when CCU is received by believing
If number acquisition device conveying includes that the signal is carried out classification and Detection, is differentiated each after stem driver acts associated command signal
Driver acts the property of associated command signal, and for each signal determining, whether it is digital quantity signal, is screened out from it simulation
Measure signal and digital quantity signal.
Then, it enters in step S120, each analog signals of the current acquisition time section of acquisition is adopted with upper one
Collection the period same kind of analog signals be changed state detection (such as: detection current time collected department
Whether machine pedal position data and last moment collected driver's pedal position data change)；If it is determined that current time
Data changed compared to last moment collected data, then record the variable condition for the signal, thus
It determines the binary digit of the analog signals, further obtains the analog quantity of the analog signals variable condition for all kinds
The binary digit of signal, wherein analog signals variable condition is indicated with binary digit；It is then determined each digital quantity signal
Binary digit (the specific data of digital quantity signal), using the binary digit of the digital quantity signal of acquisition as constitute driver movement
The data basis of the generated data of associated command signal, finally by the binary digit of above-mentioned all analog signals and all
The binary digit of digital quantity signal is integrated, and is obtained the generated data that current driver acts associated command signal, is denoted as simulation
Measure A.
It should be noted that in actual application, if acting associated command signal by a large amount of number in stem driver
It measures signal and a small amount of analog signals is constituted, wherein the jump of all digital quantity signals belongs to driver's movement, and it has
Volume data is binary digit, for example signal be low level by high level variation or to be changed by low level be high level, if one by one
It is more that signal carries out the system resource that jump monitoring then expends, it is therefore not necessary to the transitional states of digital quantity signal are detected, it can be by number
Data basis of the specific data that word amount signal acquisition arrives as above-mentioned generated data.On the other hand, it is only necessary to by a small amount of mould
The binary digit of the state change of analog quantity signal digital quantity indicates, and is changed state-detection to analog signals, solves
All drivers of detection act the resource-consuming problem in associated command signals variation.Wherein, (example) is with above-mentioned simulation
For measuring driver's pedal position data in signal, if current time driver's pedal position data and last moment collected department
Machine pedal position data is compared, and amplitude of variation is greater than a certain range, then determines that driver's pedal position data changes, then will
The variable condition of the data indicates with binary digit, such as: it when variation, is denoted as " 1 ", when not changing, is denoted as " 0 ".In addition, driver
The generated data for acting associated command signal is preset analog data, and data format acts correlation according to all drivers and refers to
It enables the type sequence definition of signal form, there is the signal sequence for representing its type since each driver acts associated command signal
Then the binary digit of all digital quantity signals and all analog signals can be written most according to defined signal sequence for row number
In whole generated data.
(example) acquires if the system includes that four drivers act associated command signal in vigilant braking control system
To after corresponding signal, digital quantity signal (its content is " 1 "), the bagpipe button of traction handle K2 gear (Serial No. 0) are obtained
Digital quantity signal (its content of digital quantity signal (its content is " 0 ") and traction pedal (Serial No. 2) of (Serial No. 1)
For " 1 ") and including drawing pedal position (Serial No. 3) analog signals, and detect and draw pedal position data
Change and the variable condition of the data is denoted as " 1 " (i.e. the binary digit of analog signals is " 1 "), since driver acts correlation
The generated data of command signal defines in such a way that signal sequence is followed successively by 0~3, therefore driver is acted associated command signal
Generated data with binary number " 1011 " indicate, synthesized the binary digit of the signal of above-mentioned four seed type.Further say,
It is able to record the binary digit of 16 variety classes signals if above-mentioned generated data is a double byte data.
It should be noted that in the embodiment of the present application, above-mentioned department is defined by the way of writing signal kinds sequence number
The motor-driven generated data for making associated command signal, the byte digit and/or its definition mode that the application is directed to the generated data are not
Make specific restriction, the application, which implements personnel, to be adjusted according to practical situations.
Then, (step S130) after obtaining current driver and acting generated data, by the data and upper acquisition time section
Driver act generated data (analog quantity B) and be compared, and judge whether the data change, therefore, it is determined that driver whether
Change movement is executed, and then exports corresponding system response action, finally saves the conjunction that current driver acts associated command signal
At data, and as the generated data of the upper acquisition time section in the program subsequent cycle.Specifically, if current driver
The generated data for acting associated command signal is consistent with the generated data of upper acquisition time section, when starting to calculate Consistency maintenance
Between, execute the early warning movement of vigilant control for brake；If current driver acts the generated data of associated command signal and upper one and acquires
The generated data of period is inconsistent, then determines that driver performs operational motion, removes the calculated Consistency maintenance time, no
Execute vigilant control for brake early warning movement.
Early warning movement below for the vigilant control for brake that system executes is further described.When above-mentioned consistency is tieed up
When holding the time more than preset first time period threshold value, then it is vigilant braking control system and exports audible ringing signal, prompt driver
It is operated, if driver changes movement, removes the above-mentioned calculated Consistency maintenance time, cancel the sound report of output
Alert signal；If driver does not operate yet, further progress determines.It is more than preset second time period threshold when the Consistency maintenance time
When value, then it is vigilant braking control system and applies full service braking, export preset full service braking data, if driver carries out
Change movement, then remove the above-mentioned calculated Consistency maintenance time, and cancels output full service braking data；If driver is still
It does not operate, then continue timing and is determined as follows, wherein second time period threshold value is greater than first time period threshold value.When above-mentioned
When the Consistency maintenance time is more than preset third period threshold value, then it is vigilant braking control system and applies the emergency brake order,
Emergency brake command signal is exported, parking is forced, wherein third period threshold value is greater than second time period threshold value.
(example)
When driver's movement is not detected in 30s lasting in driving conditions, train will be considered to driver and desert one's post, sleep
Or it is absent minded, in view of the principle of fault-safety principle, train control system first passes through man-machine interaction display screen sending
Audible alarm prompts driver, and after driver's change movement, timing clearing restarts, and stops audible alarm；Work as system
After executing audible alarm 5s, when driver does not still carry out relevant action, train control system applies full service braking, if driver holds
Row change relevant action, timing clearing restart, and stop applying full service braking；When system executes service braking operation
Driver is also unchanged when more acting after 5s, and train control system will apply vigilant Brake stop, guarantee traffic safety.
It should be noted that the maximum feature of the application is that the signal that numerous kinds are different but property is the same is combined into one
A data carry out this processing, therefore the application can be under the principle that can satisfy present invention realization thought, during implementing to it
