Description

Technical Field

[0001] The utility model belongs to the field of track railway occupancy detection, and particularly relates to a rapid track line identification instrument. Background Art

[0002] When track railway construction workers carry out construction operations, they need to work on the blocked line. However, in actual construction, most of the work is carried out during the night skylight operation time. The lighting at the operation site is insufficient, and the operation personnel are not clear about the on-site blocking situation, resulting in the problem of misidentifying the operation position, which is very likely to lead to major safety accidents of casualties. Based on this, there is an urgent need to develop a device that can be used by operation personnel to detect the track line on site to avoid traffic accidents. Content of the Utility Model

[0003] Aiming at the deficiencies described in the above prior art, the utility model provides a rapid track line identification instrument. Based on the fact that all inter-station track circuits on the whole railway adopt the ZPW-2000 system, the two steel rails of the inter-station track circuit are detected. By detecting the carrier frequency signal, it is identified whether it is the up line or the down line, because the up line uses 2000 Hz and 2600 Hz; the down line uses 1700 Hz and 2300 Hz.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A rapid track line identification instrument includes a detection host and a protective copper wire. The detection host includes a control module, a reminder module, a detection power supply module and a detection power switch. The detection power supply module supplies power to the control module and the reminder module through the detection power switch. The control module is electrically connected to the reminder module; the protective copper wire includes a first protective copper wire and a second protective copper wire. The detection end of the first protective copper wire contacts one steel rail, and the detection end of the second protective copper wire contacts the other steel rail; the other ends of the first protective copper wire and the second protective copper wire are both connected to the control module. The two protective copper wires respectively contact the two steel rails of an interval section to form a loop, and transmit the detection signal to the control module. The control module makes the reminder module give a sound and display a reminder. It is convenient for the operation personnel to know whether the measured interval steel rail is the up line or the down line.

[0006] As a preferred solution of the utility model, an adsorption magnet is arranged at the detection end of the first protective copper wire; and / or an adsorption magnet is arranged at the detection end of the second protective copper wire. The adsorption magnet is used as the acquisition contact end of the protective copper wire and the steel rail to collect the carrier frequency signal of the contacted steel rail. The magnet is arranged to facilitate contact with the steel rail for signal acquisition. Of course, other contact methods can also be adopted as long as the signal can be collected.

[0007] As a preferred embodiment of the present utility model, the first protective copper wire and the second protective copper wire are connected to the control module in a pluggable manner.

The short-circuit switch is in an open state under normal conditions. When closed, a loop is formed between the two protective copper wires, causing a short circuit between the two rails. In this state, the first protective copper wire and the second protective copper wire will no longer transmit signals to the control module. After reconnecting and disconnecting, operating the detection power switch again can realize the detection of the line type. The setting of the short-circuit switch enables the present utility model to have the function of replacing the short-circuit copper wire.

[0015] And / or the detection host further includes an indicator light circuit and a power detection line. The controller is connected to the indicator light circuit and the power detection line, and the detection power supply circuit supplies power to the indicator light circuit and the power detection line. The power detection line detects the power of the lithium battery and gives a detection signal to the controller, which is displayed on the display screen by the controller.

And in order to prevent accidental touch and misoperation, it is preferred to cover the detection power switch 13 and the short - circuit switch 14 with button protective covers 4.

[0034] The control module includes a carrier - frequency signal processing circuit and a controller.

The short - circuit switch is in an open state under normal conditions. When closed, it forms a loop between the two protective copper wires, causing a short - circuit between the two rails. In this state, the first protective copper wire and the second protective copper wire will no longer transmit signals to the control module. After reopening, operating the detection power switch can realize the detection of line types. The setting of the short - circuit switch enables the present utility model to have the function of replacing the short - circuit copper wire.

[0035] The output end of the carrier - frequency signal processing circuit is connected to the input port of the controller. The circuit diagram of the carrier - frequency signal processing circuit is as shown in Figure 5 shown.
