Railway radio shunting equipment

3.1 repeater mode operation

an operating mode of which the railway radio shunting equipment

communicates with one or more other railway radio shunting equipment via

relay equipment transfer

3.2 direct mode operation

an operating mode of which the railway radio shunting equipment directly

communicates with one or more other railway radio shunting equipment without

the use of relay equipment

3.3 test signal

the communication contact signal transmitted periodically by the shunting hand

to the shunting locomotive controller in the advancing state

4.1 General requirements

4.1.1 The operating frequency range shall comply with the relevant provisions

of the radio management.

5.1.1 The shunting equipment shall use 4 level shift keying (4FSK) digital

modulation. When the channel spacing is 12.5 kHz, it may use the multiple

access mode of time division multiple access (TDMA) or frequency division

multiple access (FDMA).

5.1.2 The port impedance of equipment antenna shall be 50 ohm.

5.1.3 The equipment shall have solid structure, good heat dissipation, clear

panel logo, easy use and maintenance, external electrical performance

measurement interface.

5.2 Locomotive controller

5.2.1 Composition

The locomotive controller can be divided into the fixed one and the portable one.

The fixed locomotive controller consists of host, driver box, display lights,

speakers, antenna and feeder. The portable locomotive controller consists of

host (with battery), driver box, antenna and train operation monitoring device

(LKJ) connection cable.

5.2.2 Functions

The equipment shall have the following functions.

a) initiating and receiving shuffler member calls;

b) receiving the shunting signaling issued by shunting personnel, lighting

display, voice prompts and issuing a response under idle, call state;

c) recording information parameters such as shunting signaling, voice and

time;

d) sending shunting signaling to LKJ.

5.2.3 Power adaptability

The power adaptability shall meet the following requirements.

a) the fixed locomotive controller shall be powered by DC power supply; the

nominal voltage is 110 V DC; the minimum operating voltage is 77 V; the

maximum operating voltage is 138 V;

b) the portable locomotive controller shall be powered by battery of the

controller; the nominal voltage is 7.2 V DC; the minimum operating voltage

is 6.3 V; the maximum operating voltage is 8.5 V.

5.2.4 Enclosure rating

The equipment shall have the following functions.

a) initiating and receiving shuffler member calls;

b) initiating calling operator signaling;

c) issuing the shunting signaling to locative controller and receiving response

under idle, call state;

d) issuing the test signal to locative controller under idle, call state;

e) alarming at low voltage.

5.4.2.2 Link, brake hand-held station

The equipment shall have the following functions.

a) initiating and receiving shuffler member calls;

b) receiving the response of locative controller;

c) issuing test signal to locative controller when pushing trolley in the case of

sending test signal of shunting operator hand-held station;

d) issuing emergency stop shunting signaling under any working state;

e) unlocking the emergency stop signaling sent by itself;

f) alarming at low voltage.

5.4.3 Power requirements

It uses rechargeable lithium battery, NiMH battery under the low temperature

environment below 25°C.

5.4.4 Enclosure rating

It shall meet requirements of IP 57 in GB 4208-2008.

5.4.5 Structural requirements

The structure shall meet the following requirements.

a) it shall be easy to operate in hand-held or body hanging conditions;

b) the antenna shall be durable and not easy to break;

c) the panel sets three buttons, V-shaped symmetrically layout; the key

position and the color are shown in Figure 1. Keyhole is round. Keyhole

size is 8 mm <= D <= 10 mm (D refers to keyhole diameter). Key height is 1

provisions of equipment safety requirements in GB 15842-1995.
