Description

System and Method for controlling cable installment between towers}

The present invention relates to a technology for controlling wire installation between pylons, and more particularly, by remotely measuring a tension value applied to a wire in real time to calculate a wire deflection value when installing an overhead transmission line wire, and based on this, the wire installation between the pylons is performed. It is about the system and method of controlling.

In general, when an overhead transmission line is installed, an electric wire is pulled using equipment to connect the electric wire between the pylon and the pylon. In this installation process, the operator measures the electric wire sag value with the naked eye using a measuring instrument, and when the electric wire sag value to be constructed is reached, the equipment is stopped to complete the work of pulling the electric wire. The electric wire deflection value generally refers to the maximum vertical distance between the straight line connecting the two support points and the curve made by the electric wire when the electric wire is supported between two support points.

However, in this method, because the operator measures the deflection value of the wire with the naked eye using a measuring instrument, there are restrictions on the field conditions due to weather conditions (fog, etc.), obstacles (trees, etc.), and long distance locations. There is a problem that an error may occur when measuring the deflection value.

In order to overcome the limitations of the field conditions that occur when measuring the wire deflection value as above, an automatic ear canal calculation device has been initiated. When measuring the wire deflection value, it is possible to automatically calculate the wire deflection value by inputting various conditions into the invention installed on the wire when installing the distribution line by utilizing the advantage of the tension meter method that can overcome the constraints of the field conditions. Compared with the applied tension value, an alarm can be given to the operator.

In this case, it is necessary to input various complex condition values in the field, and a complex mechanism that can be applied to the wire installation work by calculating the desired wire deflection value by comparing the calculated value with the applied tension value is required. There is this.

In addition, in order to check the value of the tension applied to the device installed on the track, there is a problem in that the worker is exposed to a dangerous work environment as the worker must directly climb the track to check.

Hereinafter, a system and method for controlling wire installation between pylons according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram of a wire installation control system 100 between pylons according to an embodiment of the present invention. Referring to FIG. 1, the wire installation control system 100 between towers may include a tensioner 110, a digital tension meter 130, a remote inspection device 123, and the like.

When installing the electric wire 10 of the overhead transmission line, the tensioner 110 and the work vehicle 120 are used to connect the electric wire 10 between the first pylon 101a and the second pylon 101b. ) Is pulled. Of course, at this time, the electric wire 11 hangs on the first support point 1a of the first pylon 101a, and the left end of the electric wire 11 is connected to the tensioner 110. The tensioner 110 may be temporarily fixed to the ground 20 by applying tension to the electric wire 11.

In addition, the electric wire 11 spans the second support point 1b of the second pylon 101b, and the right end of the electric wire 11 is connected to the digital tension meter 130. Accordingly, the digital tension meter 130 is disposed between the right end of the wire 10 and the left end of the wire 11 and is connected to each other.

The digital tension meter 130 has a ring structure (not shown) that can connect the ends of the wires 10 and 11 at both ends, and this ring structure is a tension value measured by tension at both ends to generate a real-time measurement tension value do.

Usually, sagging of the electric wire 10 occurs during this installation process. The electric wire deflection value (i.e., the second degree value) 102 has the greatest difference between the virtual straight line connecting the support points 1a and 1b between the first pylon 101a and the second pylon 101b and the sagging wire 10. A large place can be a criterion. In other words, the electric wire deflection value generally refers to the maximum vertical distance between the straight line connecting the two support points and the curve made by the electric wire when the electric wire is supported between the two support points.

The wire deflection value 102 represents a different value for each location due to differences in spans and elevation differences between the two towers, and the tension value applied to the wires between the towers may be calculated using an island calculation program. The ear canal calculation program calculates a user-set tension value corresponding to the condition data when condition data such as span and height difference are input using a previously collected database. Accordingly, a server (not shown) for separately operating the ear canal calculation program is configured. Since the ear canal calculation program technology is widely known, further description will be omitted.

Therefore, the user calculates the tension value set by the user in advance by the ear canal calculation program, and inputs it to the remote inspection device 123, so that the remote inspection device 123 can obtain the measured tension value transmitted from the digital tension meter 130 in real time. It is possible to compare user-set tension values and output alarm information according to the comparison result.

The digital tension meter 130 calculates a real-time measurement tension value of the electric wire 10 and transmits it to the remote inspection device 123. To this end, the remote inspection device 123 is configured with a communicator 122. In addition, when the wire 10 is pulled in the right direction through the work vehicle 120, a change occurs in the tension of the wire 10, and the digital tension meter 130 measures this to generate a real-time measured tension value. .

Of course, when the electric wire deflection value to be measured and constructed is reached, the user 121 stops the operation of the engine puller 124 configured in the working vehicle 120 to complete the wire pulling operation. The engine puller 124 is connected to the power of an engine (not shown) in the vehicle and functions to wind or unwind the electric wire 10 by using a rotational force.

Referring to FIG. 2, the digital tension meter 130 may include a first control unit 210, a measurement unit 220, and a communication unit 230. The first control unit 210 exchanges control signals and data with components, and performs control. In particular, when the tension value is measured, it is transmitted to the remote inspection device 123 through the communication unit 230 in real time. To this end, the first control unit 210 may include a processor, an electronic circuit, and a program.

The measurement unit 220 performs a function of generating a measured tension value in real time by measuring tension generated by the wires 11 and 10 connected to both ends pulling each other. To this end, the measurement unit 220 may include a load cell that measures tension, an A/D (Analog/Digital) converter that converts an analog measurement signal into a digital measurement signal, an amplification circuit that amplifies an analog signal, and the like.

Referring to FIG. 3, the remote inspection device 123 may include an exterior housing 310, a display unit 320, an input unit 330, an alarm unit 340, and the like.

Referring to FIG. 4, it may include a display unit 320, an input unit 330, an alarm unit 340, a second control unit 400, a comparison unit 410, a determination unit 420, and the like. The second control unit 400 exchanges control signals and data with components, and performs control. The input unit 330 receives a condition by a user's manipulation.

The comparison unit 410 compares the tension value calculated by the user input by the user and the tension value measured in real time transmitted from the digital tension meter 130. Since the wire deflection value according to the tension value is determined, each wire deflection value is calculated from the real-time measured tension value and the user calculated tension value. That is, the wire deflection value may be configured as a lookup table corresponding to the tension value.

The determination unit 420 compares the real-time measured tension value and the user-calculated tension value, generates alarm information for each stage according to the ratio of the real-time measured tension value to the user-calculated tension value, and displays the display unit 320 to the user. ) And/or the alarm unit 340 to provide alarm information.

5 is a flowchart illustrating a process of remotely measuring a tension value according to an embodiment of the present invention and controlling the installation of wires between pylons based on this. 5, a user calculated tension value is input to the input unit 330 (step S510). Of course, a real-time measured tension value may be transmitted from the digital tension meter 130 before or at the same time as the user-calculated tension value is input (S501).

Thereafter, the comparison unit 410 calculates the ratio of the tension value calculated by the user and the tension value measured in real time (step S520).

Thereafter, the comparison unit 410 compares the ratio of the tension value calculated by the user and the tension value measured in real time with a reference value (step S530). In other words, the real-time measured tension value is compared with the reference value as to what% of the real-time measured tension value. Of course, the reference value becomes 100%.

Accordingly, alarm information is generated and output for each stage. That is, it is composed of a notice alarm stage (S541, S542) for outputting notice alarm information, a match alarm stage (S550) for outputting match alarm information, and a warning alarm stage (S543) for outputting warning alarm information.

In the case of the notice alarm stage (S541, S542), if the real-time measured tension value is 80% of the user-calculated tension value, a first notice alarm occurs (S541), and if the real-time measured tension value is 90% of the user-calculated tension value, A second notice alarm occurs (S542). Of course, it is not strictly 80% or 90%, and in the case of 70% to 80%, it may be a first notice alarm, and if it is 81% to 97%, it may be a second notice alarm.

In the case of the coincidence alarm stage S550, when the real-time measured tension value is 100% of the user-calculated tension value, the coincidence alarm occurs because it coincides with the reference value (100%). Of course, it is possible to set the reference value to 98% to 102% in consideration of the error.

In addition, in the case of the warning alarm stage S543, when the real-time measured tension value is greater than 100% of the user calculated tension value, a warning alarm is generated so that the wire 10 is no longer pulled.
