In subway, train generally provides the mode for configuring end to end, and the two ends of each fixed car group all respectively equip a set of vehicle-mounted
Equipment, as shown in Figure 1.In general, the mode of present Vehicle Controller (VOBC) and Train Control takes circuit side connector
Formula, according to certain mark and requirement arrangement circuit between Vehicle Controller and train signal point.According to the safety of signal
Source can be divided into safe input, Safety output, non-security input, non-security output, their connection principle such as Fig. 2-5 institutes
Show.
Controls of the existing VOBC to train can the explanation by taking controls of the VOBC to train traction and braking as an example.ATO is carried
Traction is represented respectively with braking for switching value all the way, 0/1.ATO provides pwm signal output all the way, and the output area of the interface is
0 100% dutycycle, 10%-90% dutycycles are range of linearity setting value, and which is equivalent to pull strength/brake force 0 to 100%
Setting value.When dutycycle is less than 5% or is more than 95%, it is believed that pwm signal failure, trailer system is without traction and electric braking, system
Dynamic system does not apply braking under non-brake operating mode, under damped condition applies full service braking；When pulsewidth is more than 5%, and
During less than 10%, it is believed that PWM outputs 10%；When pulsewidth is more than 90% and is less than 95%, it is believed that pwm signal output 90% (5%

Size export different dutycycles.
Control car is carried out by the way of existing VOBC and train information point are directly connected to, between VOBC and train information point
Wiring is complicated, high cost.Once circuit is out of joint, difficult, replacing inconvenience is searched, is unfavorable for the maintenance of later stage train, it is practical
Property is poor.
In addition, by electromagnetic interference and the precision of acquisition chip, the PWM waveform of the ATO outputs that train is collected has ripple thorn,
The unstable of speed is caused, the comfortableness of train is reduced, the fluctuation of speed in addition can also cause unnecessary traction and braking, make
Into the waste of the energy.When fluctuating larger, even can cause brake hard sometimes, potential safety hazard be brought to train passenger.
