A specific embodiment of the invention is further described below in conjunction with attached drawing.
Track train traction braking level is mostly derived from signal system output (VOBC) and the people of automatic driving mode (ATO)
The controller (MC) of work driving mode exports.VOBC output and the train network control system interface mode of ATO mode are rigid line
Signal, usually 4-20mA current signal or 0-10V voltage signal, in recent years leading of exporting of signal system in subway train project
It is in the majority with 4-20mA current signal to draw braking level signal.The MC output of pilot steering mode and the interface mode of TCMS are rigid line
Signal, usually 0-10V voltage signal or pwm signal, the traction braking level that MC is exported in subway train project in recent years are believed
It is number in the majority with 0-10V voltage signal.The present embodiment devises traction braking by taking the control of the traction braking level of subway train as an example

Specifically, the present embodiment is set based on the VOBC 0-20mA current signal exported and MC the 0-10V voltage signal exported
Meter.I.e. under ATO mode, with the current signal I of signal system outputoRepresent traction braking level information；Under pilot steering mode,
With the output voltage U of controlleroWith output reference voltage UrefRatio Rate=Uo/UrefRepresent traction braking level information.Ginseng
It examines shown in Fig. 1, TCMS system acquires automatic Pilot mould by two independent remote input output unit RIOM1, RIOM2 redundancies
The two-way of the controller output of the independent traction braking level information of two-way or pilot steering mode of the signal system output of formula
Independent traction braking level information.
(2) real time communication diagnosis is carried out to remote input output unit RIOM；It is adopted according to remote input output unit RIOM
The traction braking level information of collection, respectively to the track train traction braking level of automatic driving mode or pilot steering mode into
Row control.
It is specific:
Under train automatic Pilot (ATO) mode:
It is examined 1. remote input output unit RIOM1, RIOM2 carry out real time communication to the IO analog input card of its own respectively
It is disconnected, if the IO analog input card of RIOM1, RIOM2 communication abnormality occur simultaneously, switches driving mode and carry out fault cues；If
There is communication abnormality in the IO analog input card of RIOM1 or RIOM2, then carries out fault cues.
That is: RIOM1 and RIOM2 carries out real time communication diagnosis to its own IO analog input card first, and I O board card passes through RIOM
Diagnostic result is uploaded to TCMS by MVB bus by core bus and RIOM CPU board card real time communication, CPU board card, and TCMS is adopted
The premise of letter RIOM acquisition data is that I O board cartoon letters are normal, if some I O board cartoon letters is abnormal, TCMS will not acquire the I O board
Block the signal of acquisition, and export diagnostic message, provides fault cues.If only the I O board cartoon letters of 1 RIOM are abnormal, carry out
Following fault cues: I O board card failure or communication abnormality, it is proposed that overhaul plan is carried out after train Hui Ku；If RIOM1 and RIOM2
I O board card simultaneously there is communication abnormality, then carry out following fault cues: RIOM1 and RIOM2IO board simultaneous faults or communication
It is abnormal, it is proposed that exit ATO mode and stood to terminal using the operation of pilot steering mode, demobilization goes back to library and carries out overhaul plan.
Specifically, in the present embodiment, the current signal that VOBC is exported under ATO mode is corresponding with level to be closed shown in reference table 1
System is as shown in the table:
| ATO exports analog signals 0-20mA (Io) | Traction braking level |
| Io< 2mA | In vain |
| 2mA≤Io< 4mA | 0% |
| 4mA≤Io≤18mA | 0-100% |
| 18mA < Io≤19mA | 100% |
| Io> 19mA | In vain |

The signal is accepted and believed, and exports diagnostic message, provides fault cues.If only the current signal of the I O board card acquisition of 1 RIOM is not
In effective range, then carry out following fault cues: RIOM1 or RIOM2 acquisition current signal transfinites, and it is laggard to establish train go back to library
Row overhaul plan；If the current signal of RIOM1 and RIOM2 acquisition not in effective range, carries out following fault cues:
RIOM1 and RIOM2 acquisition current signal is abnormal, it is proposed that and it exits ATO mode and is stood to terminal using the operation of pilot steering mode, demobilization

3. trusting the traction level smaller value of RIOM1, RIOM2 acquisition if train is in traction state；If train is in
On-position then trusts braking level the larger value of RIOM1, RIOM2 acquisition；If the deviation of signal of RIOM1, RIOM2 acquisition is super
Preset threshold value is crossed, then carries out fault cues.
Specifically, if TCMS judges the equal normal communication of I O board card of RIOM1 and RIOM2, and the 0-20mA of RIOM1 acquisition
Current signal Io_RIOM1With the 0-20mA current signal I of RIOM2 acquisitiono_RIOM2The 2-19mA in effective range, then by following rule
Then carry out logical process:
When train is in traction state, then the traction level smaller value of RIOM1 and RIOM2 acquisition is trusted；If train is in
On-position then trusts braking level the larger value of RIOM1, RIOM2 acquisition.If the current signal of RIOM1 and RIOM2 acquisition
Deviation | Io_RIOM1-Io_RIOM2When | > 1mA, then logical process still is carried out by above-mentioned rule, while exporting diagnostic message, to being out of order
Prompt: RIOM1 and RIOM2 acquisition current signal deviation is more than 1mA, it is proposed that overhaul plan is carried out after train Hui Ku.
4. if the traction braking level information of RIOM1 or RIOM2 redundancy acquisition signal system output is not preset effective
In range, then the RIOM1 in effective range or the traction braking level information of RIOM2 acquisition are accepted and believed, and carry out fault cues.
If RIOM1 or RIOM2 redundancy acquires the traction braking level information of signal system output not in preset effective range,
Execute step 5..
Specifically, when TCMS judges to have in RIOM1 and RIOM2 a RIOM acquisition current signal invalid, that is, Io< 2mA
Or IoWhen > 19mA, then the traction braking level signal of another RIOM acquisition is accepted and believed, and export diagnostic message, mentioned to being out of order
Show: RIOM1 or RIOM2 acquisition current signal is invalid, it is proposed that overhaul plan is carried out after train Hui Ku.
5. if traction level is forced to 0% by TCMS, and control train is in inert condition when train is in traction state；
If train is in on-position, traction level is forced to 100% by TCMS, and control train applies full service braking, and locks
Level signal is braked, until suspension of service；If driver artificially applies the emergency brake, control train enters emergency braking mould
Formula；Fault cues and control be switched to pilot steering mode.
Specifically, if TCMS judges that the signal of RIOM1 and RIOM2 acquisition is invalid, i.e.,AndThen: if train is in traction state, traction level is forced to 0% by TCMS, and control train is in
Coasting state；If train is in on-position, TCMS will brake level position and be forced to 100%, and control train applies maximum normal
With braking, and braking level signal is locked, until train speed is reduced to 0, guarantees the orderly shutdown of vehicle energy, guiding safety.At this time
If driver artificially applies the emergency brake, train will enter emergency brake modes, i.e. emergency braking highest priority.Meanwhile it is defeated
Diagnosis is as a result, provide fault cues out: RIOM1 and RIOM2 acquisition current signal is invalid, it is proposed that exits ATO mode using people
Work driving mode continues operation and stands to terminal, and demobilization goes back to library and carries out overhaul plan.
