Specification of railway signal axle counter
application system
1 Scope
This standard specifies the terms and definitions AND technical requirements
for the axle counter application system.
This standard is applicable to the automatic block, automatic inter-station block,
and inter-station interlock system which are composed of the axle counter track
inspection device. It is the technical criterion for researching, designing,
manufacturing and using.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
Axle counter train detection device
It refers to the safety device which realizes the cleared and occupied
inspection of the track section through the arithmetic calculation of the
counting in and counting out axle number AND output of control conditions.
2.2
Axle application system
It refers to the application system which is composed of the axle counter train
detection device and the signal circuit.
2.3
Axle track section
It refers to the cleared track section as checked by the axle counter train
detection device.
2.4
Cleared
c) When the axle counter train detection device and the available inner-
station track circuit are combined to settle the issue that the low resistance
track bed circuit cannot be adjusted for once, the axle track relay and this
section track circuit relay can be connected in parallel;
d) When the axis track section is reset, it shall, after manually confirming that
this section has no train, adopt instant reset mode.
3.7 Automatic inter-station block of axle counting shall meet the following
requirements.
a) The axle counter train detection device completes the inter-section cleared
and occupied state inspection;
b) When the departure station handles the departure route, the inter-station
will automatically switch to the block state;
c) When the train arrives at the reception station or returns back to the
departure station, after confirming that the inter-section is cleared, it shall
automatically terminate the block state;
d) After the inter-section block and before the departure route is unlocked, it
shall not terminate block; after cancelling the departure route and the
departure route is unlocked, the block is automatically terminated
accordingly;
e) When the inter-section axle counter train detection device is reset, after
manually confirming that the inter-section is cleared by both stations,
BREAK the lead seal, AND both stations shall simultaneously operate the
instant reset button within 13 s;
f) The system shall make use of relevant inner-station interlocking conditions
and take other measures to realize the logic judgment function of
distinguishing normal traffic and external interference;
g) The system shall be powered by an uninterruptible power supply, which
shall, after an interruption of the AC power supply, guarantee the time
required by the normal operating train from departure to completely reach
to the reception station.
3.8 The automatic block axis application system shall meet the following
requirements.
a) The system shall have a large section axle counting detection function.
When the block section is in occupied state AND required for reset, it shall
5) The loop current is not less than 600 mA, to ensure reliable reception
of locomotive signals;
6) The loop shall be fixed reliably every 2 m;
7) The loop shall have locomotive signal code sending, code cutting,
disconnection, and short-circuit detection alarming and indication.
3.9 The communication transmission channel shall meet the following
requirements.
a) The inter-station and indoor-outdoor equipment communication
transmission channel of the axle counting system shall adopt the special
transmission line pair (optical cable or symmetrical cable).
b) The axle counting system shall continuously monitor its communication
transmission channel; when this channel has fault, the corresponding axle
track section shall be at occupied state, AND meanwhile indication is
provided.
3.10 It shall equip reliable power supply to ensure the uninterrupted normal
operation of the system.
3.11 The axle counting system shall have a fault alarm function; once fault
occurs, the corresponding axle track section shall be at occupied state, AND
meanwhile indication is provided.
3.12 The axle counting system shall have a standard interface, AND the
information can be included in micro-computer monitoring, computer
interlocking, TDCS (train dispatching command system), and CTC (centralized
traffic control).
3.13 The channels, equipment, power supply, etc., of the axle counting system
shall be confi......
