Description

TECHNICAL FIELD [0001] The present invention relates to a monitoring system and method,

The present invention relates to a tension monitoring system and method for remotely monitoring an amount of tension change of an electric railway tension line, and more particularly, And more particularly, to a tension control device monitoring system and method for providing advance monitoring and alarm recognition through automatic remote monitoring.

In electric railways such as trains, high-speed railways, and subways, electric railways need to be installed to supply electric power to electric railway vehicles. In such an electric cable, there is a electric cable which directly contacts with the electric power collecting device of the electric railway vehicle to supply electric power, and there is a jig that is jammed to keep the electric cable at the same height horizontally. An automatic tension adjuster is used to pull the wire and the wire with constant tension.

The automatic tension adjusting device includes a pulley type pulley, a pulley type pulley, a spring type pulley, and the like. The automatic pulley type pulley type automatic tensioner is, for example, as shown in FIG.

1 is a view for explaining an example of a generally used pulley type automatic tension adjusting device.

A power collecting device 10 composed of a current collecting plate 12 and a supporting portion 14 is installed on an electric railway vehicle 1 in order to supply electric power to the electric railway car 1. [ The electric line 30 for transferring the electric power is constituted by the electric wire 32 and the wire 34. The electric wire 32 is in direct contact with the current collecting device 10 to supply electric power, (34) performs a function of tightening the catenary line (32) to keep the catenary line (32) at the same height horizontally.

The automatic tension adjusting device 40 includes a tension weight 42, a weight guide rod 44, an upper ground portion 48, a lower portion ground 47, a large pulley 46, a small- (49), a wire b (43), and the like.

At this time, the pulley is composed of a large pulley 46 and a small pulley 45, both of which are integral. The small-sized car 45 winds the wire a 49 and the large-diameter pulley 46 winds the wire b 43. The circumferential length of the portion where the wire a 49 is wound in the small automobile 45 and the circumferential length of the portion where the wire b 43 is wound in the large swing gap 46 are different from each other, The moving distance of the wire a 49 and the wire b 43 is changed by the amount of movement of the wire a 49 and the wire b 43.

For example, if the pull ratio of the small vehicle 45 and the large pulley 46 is 1: 4, if the wire a 49 is wound 10 cm to the small vehicle 45, the wire b 43 is pulled by the large pulley 46, Resulting in a 40 cm loosening. The tension weight 42 functions to add a constant tension to the wire b 43. The tension applied to the wire b 43 is amplified by the amount corresponding to the above-mentioned pull ratio to be caught by the wire a 49, The wire 32 and the wire 34 to pull the electric wire 30 with a predetermined tension. The lower guide member 47 and the upper guide member 48 are installed on the support 22 to support the guide rods 44. The guide rods 44,

In the meantime, in order to alert the occurrence of such an emergency situation on the electric line 30 because the electric line 30 may be disconnected, conventionally, the position sensor 51 and the electric line management panel device 50 are used There was technology. As shown in Fig. 1, the position sensor 51 is attached to the strut 22 and is disposed toward a path through which the tension weights 42 can flow.

The position sensor 51 in the prior art seems to sense the presence of the tension weights 42 at certain points. When the emergency situation such as disconnection of the electric wire 30 occurs, the tension weight 42 will move in the direction close to the lower land 47. The position of the position sensor 51 is set at a specific distance from the lower support 47. When the weight 42 descends and falls below the measurement position, the position sensor 51 detects the position. Accordingly, the sensed signal is transmitted to the catenary management panel device 50, and the catenary management panel device 50 reports the status of the electric line 30 to a central management server (not shown).

As described above, according to the above-described conventional technique, it is possible to sense and alarm that the tension weight 42 is lowered below the preset threshold line in an emergency situation such as disconnection of the electric wire line 30. [ The above-described conventional technique can only detect an emergency situation such as disconnection of the electric cable 30 and alarm.

However, when the temperature of the electric wire 30 is increased and the temperature of the electric wire 30 is increased, if the automatic tension adjuster 40 is normal, the tension weight 42 is lowered to prevent the electric wire 30 from sagging. If the automatic tension adjuster 40 is normal, the constant tension is always supplied to the electric line 30 to prevent the electric line 30 from sagging. However, a situation may arise in which the pulley may not flow due to an abnormality in the pulley, for example. The tension weight 42 should be able to flow while being guided by the weight guide rod 44. However, there may be a situation where the tension weight 42 can not be pushed into the weight flow rod 44 due to some reason.

When the temperature rises in this state, the tension weight 42 of the automatic tension adjuster 40 can not descend even if the electric line 30 extends, so that the electric line 30 loses its tension, I will sag.

However, in the related art, it is possible to sense that the tension weight 42 is lowered below the limit line, but it can not be detected when there is no flow of the tension weight 42. If an abnormality occurs in the automatic tension adjuster 40, even if an emergency occurs in which the electric wire 30 sags, the prior art can not detect and report it. Further, when the temperature is lowered in a state in which the automatic tension adjuster 40 is abnormal and the pulley can not flow, the length of the electric wire 30 is shortened, so that a tension greater than the tension specified in the electric wire 30 is applied However, the conventional technology can not detect and report such a situation.

On the other hand, the length of the catenary line 32 can be reduced due to the abrasion and aging of the catenary line 32 as well as expansion and contraction of the catenary line 32 in accordance with the temperature. In addition, when the catenary line 32 is first installed, the pre-stretch is not performed or the catenary line 32 is damaged due to the material of the catenary line 32, so that the catenary line 32 may be rapidly extended after the construction. Preferably, the length of the catenary line 32 should always be the same at the same temperature, but even if the temperature of the catenary line 32 is the same at the same temperature due to lack of pre-stretch, abrasion of the catenary line 32, material failure, 32 may be reduced in length.

According to the related art, it is possible to sense that the tension weight 42 is lowered below the set threshold line, so that it is possible to detect the elongation of the limit line length by setting the limit of the extension of the electric wire 32. However, since the catenary line 32 expands and contracts in accordance with the change in temperature, the lowering of the tension weights 42 below the limit line is caused by the change in the temperature (i.e., the high temperature) It is impossible to distinguish the amount due to material failure or aging. Therefore, according to the related art, it is difficult to detect whether there is an abnormality caused by abrasion of the catenary line 32, material failure or aging.
