Description

  The present invention relates to an output confirmation method and an output confirmation apparatus for confirming whether or not a signal is output only from a specific output terminal among a plurality of output terminals.

  Many output terminals are provided in monitoring devices and control devices installed in a power plant, an electric plant, etc., and an input signal is transmitted to an output terminal corresponding to a predetermined condition. For this reason, when installing a controller or changing settings, check whether the correct output signal is being output to the correct output terminal with respect to the input, and whether there is no output other than the correct output terminal. An output verification test is being conducted. In the input / output confirmation test, it was necessary to confirm the output signals of all output terminals using a tester or the like, and the input / output confirmation test required time and effort. For example, when 1000 output terminals are provided in the control device, if there is only one correct output terminal, not only that the output terminal has a correct output but also the remaining 999 outputs. It is necessary to confirm that there is no output for each terminal.

  As a conventional technology related to the input / output confirmation test, when the RFID tag and the RFID of the terminal block cover are read by the RFID reader, the cable construction support determines whether the core wire is connected to the correct terminal based on the associated information. A technique related to a system, a terminal block plate, and a cable construction support method is known (for example, see Patent Document 1). In addition, a plurality of parallel arrangements of detectors composed of conductive contacts that contact the output terminals or input terminals of the terminal block, energization indicator lamps, and resistance elements, conductors connected to the resistance elements, and the conductors There is known a technique related to a current-carrying confirmation tool for a terminal block, in which a cover body including a ground metal contact that is connected and contacts an earth connection metal fitting is formed of an insulator (see, for example, Patent Document 2).

  By the way, in input / output tests for monitoring devices and control devices, it is necessary to check whether the correct output signal is being output to the correct output terminal with respect to the input, and whether there is no output to other than the correct output terminal. There is a problem that it takes a lot of time. In other words, in order to confirm the presence or absence of output in a control device or the like, it is necessary to individually check each output terminal with a measuring instrument such as a tester, which entails a huge amount of work and a very long time. .

  Accordingly, an object of the present invention is to provide an output confirmation method and an output confirmation apparatus that can solve the above-described problems and can efficiently confirm an output in a short time.

  In order to solve the above problem, the invention according to claim 1 is an output confirmation method for confirming whether or not a signal is output from only a specific output terminal among a plurality of output terminals, An integral signal conductor for passing a signal is connected to all the output terminals except the specific output terminal, and it is confirmed that an output signal corresponding to the input signal is output from the specific output terminal, and It is characterized by confirming that it is not output from a signal conductor.

  According to the present invention, when a signal output is confirmed at a specific output terminal and no signal output is confirmed at the signal conductor, it is determined to be normal. In other cases, it is determined that the output is not correct or there are multiple outputs.

  The invention according to claim 2 is an output confirmation device for confirming whether or not a signal is output from only a specific output terminal among a plurality of output terminals, and is connected to and disconnected from the output terminal. A plurality of flexible connecting / disconnecting portions are provided corresponding to the positions of the output terminals, and the specific signal conductor through which the signal is passed and the connecting / disconnecting portion of the signal conductor are connected / disconnected. And a measuring device for confirming the presence / absence of a signal from the terminal and the presence / absence of a signal from the signal conductor.

  According to this invention, the signal from the specific output terminal is connected with the connection / disconnection portion of the signal conductor connected to the specific output terminal and the connection / disconnection portion connected to all the other output terminals. Check the presence or absence of signals and the presence or absence of signals from the signal conductor with a measuring instrument. When the signal output is confirmed from the specific output terminal and the signal output is not confirmed from the signal conductor, it is determined to be normal. Further, the signal conductor can be easily separated from the terminal block in a short time.

  According to the first aspect of the present invention, it is only necessary to confirm that the output signal corresponding to the input output signal is output from the specific output terminal and not to output from the signal conductor. For this reason, even when checking for a large number of output terminals, it is possible to efficiently check the output in a short time, and the labor for checking the output can be greatly reduced.

  According to the second aspect of the present invention, only a signal conductor provided with a plurality of connection / disconnection portions and a measuring device for checking the presence / absence of a signal are provided, and confirmation is made for a large number of output terminals. However, it is possible to efficiently confirm the output in a short time, and the labor for confirming the output can be greatly reduced. Further, since only the signal conductor and the measuring instrument are provided, the configuration is simple, and the apparatus can be manufactured easily and inexpensively. In view of the fact that the signal conductor can be easily detached from the terminal block in a short time, when checking the output of a plurality of terminals continuously, the working time can be greatly reduced and the work safety can be reduced. It is possible to improve the performance.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 4 show an embodiment of the present invention. FIG. 2 shows a control device 50 of, for example, related facilities for power transmission and distribution to which the output confirmation method of the present invention is applied. The control device 50 has a plurality of terminal boards 100. Each terminal board 100 has a plurality of output terminals 101. The control device 50 outputs an output signal from a specific output terminal 101T. Here, in this embodiment, a one-second pulse signal (DC voltage 110 V) is output. As shown in FIG. 1, the output terminals 101 are arranged on the terminal board 100 side by side with a predetermined interval d1. The output terminal 101 has a connection screw 102, and an electric wire (not shown) is connected to the output terminal 101 by tightening the connection screw 102. As shown in FIG. 2, the control device 50 is provided with an earth bar 51 to which a ground line A is connected.

  The output confirmation device 1 is composed of a wire 10 as an integral signal conductor for passing signals and testers (circuit meters) T1 and T2 as measuring instruments. Here, the tester T1 confirms whether or not a signal is output from a specific output terminal 101T, and the tester T2 confirms whether or not a signal is output from the wire 10.

  The wire 10 is formed with a plurality of connecting / disconnecting portions 12 that can be connected to and disconnected from the output terminal 101 corresponding to the positions where the output terminals 101 are arranged. The wire 10 can be bent in any direction and can be deformed into an arbitrary shape. In the output check device 1 in this embodiment, as shown in FIG. 3, one wire 10 is formed in a continuous wave shape, and straight portions 13 are formed at both ends of the wire 10. The interval between adjacent connecting / disconnecting portions 12 is d2, which is set substantially equal to the interval d1 between adjacent output terminals 101. As shown in FIG. 1, the wire 10 is tightened with the connecting screw 102 in a state where the connecting / disconnecting portion 12 protruding toward the output terminal 101 is in contact with the outer periphery of the conductor portion 102 a of the connecting screw 102, whereby the output terminal 101. To be connected to.

  Here, the wire 10 of the output confirmation apparatus 1 is manufactured by the jig 200 shown in FIG. In the jig 200, two long plate members 201 and 202 are rotatably connected via hinges 203 and 204. On the plate 201, a plurality of pins 205 are arranged in a line at equal intervals with a distance d3 inside a predetermined distance from the end in the longitudinal direction. Here, the distance d3 is set substantially equal to the distance d1 between the output terminals 101 of the terminal board 100. On the plate 202, a plurality of pins 206 are arranged in a line at equal intervals at a distance d3 at a position facing an intermediate portion between the pins 205 arranged on the plate 201. That is, the pins 205 of the plate material 201 and the pins 206 of the plate material 202 are arranged so as to alternate. Further, the hinges 203 and 204 allow the plate members 201 and 202 to be rotated (foldable) in a direction in which the sides on which the pins 205 and 206 are disposed approach each other (arrow direction in the figure). .

  Next, the manufacturing procedure of the wire 10 will be described. As shown in FIG. 4, the jig 200 is held in a state where the hinges 203 and 204 are opened (the plate members 201 and 202 are substantially horizontal). First, in a state where tension is applied to one wire 10, they are alternately brought into contact with each other so as to be wound substantially half a circumference from the end of the jig 200 along the outer periphery of the pins 205 and 206. That is, the wire 10 is bent in contact with the pins 205 and 206 to form a corrugated shape, and a plurality of connecting / disconnecting portions 12 corresponding to the arrangement positions of the output terminals 101 are formed. Then, after the wire 10 is brought into contact with all the pins 205 and 206 on the jig 200, the hinges 203 and 204 are rotated so that the plate members 201 and 202 are folded in a direction approaching each other. At this time, the wire 10 is in a relaxed state because the tension is not applied.

  Next, the wire 10 is removed from the jig 200, and the production of the corrugated wire 10 used in the output check device 1 is completed. Even if the number of output terminals 101 of the terminal board 100 using the output check device 1 is larger than the connection / disconnection portion 12 of one wire 10, a plurality of wires 10 are prepared and desired. A wire 10 having a number of connection / disconnection portions 12 (depending on the number of output terminals 101 of the terminal board 100) can be manufactured. That is, after forming the plurality of wires 10 into a corrugated shape, the wire 10 having the desired number of connecting / disconnecting portions 12 is obtained by repeatedly twisting and connecting the straight portions 13 of the two wires 10 together. Can do. More specifically, for example, if the number of output terminals 101 arranged on the terminal board 100 is 1000 and the number of connecting / disconnecting portions 12 molded into one wire 10 by the jig 200 is 100, 10 wires 10 are formed into a corrugated shape, and 10 wires 10 are connected by twisting the straight portions 13 together to produce one wire 10 having 1000 connecting / disconnecting portions 12. can do.

  Next, an output confirmation method using the output confirmation apparatus 1 will be described.

  First, as shown in FIG. 2, the wire 10 is moved to the vicinity of the terminal board 100 of the control device 50 in which the wiring work is completed. Then, the connection screws 102S are tightened in a state where the connection / disconnection portions 12 of the wire 10 are sequentially in contact with the connection screws 102S of all the output terminals (output terminals) 101S except the specific output terminal 101T. The unit 12 and the output terminal 101S are connected. At this time, the outer periphery of the connecting / disconnecting portion 12 is in contact with the conductor portion 102Sa of the connecting screw 102S, and the connecting / disconnecting portion 12 is pressed against the output terminal 101S by the connecting screw 102S. In this way, all the output terminals 101S are connected in series by the wire 10. A tester T1 is connected to a specific output terminal 101T that is not connected to the output confirmation device 1.

  Next, the power supply is energized to input and transmit a pulse signal, and the output values of the testers T1 and T2 are confirmed. The voltage of the specific output terminal 101T is confirmed by the tester T1, and for example, it is confirmed that the voltage is 110V, that is, the output signal is detected. Further, the voltage of the output terminal 101S is confirmed by the tester T2, and it is confirmed that the voltage is 0V, that is, the output signal is not detected. As described above, when the voltage is measured only at the specific output terminal 101T and the voltage at the output terminal 101S is 0V, it is confirmed that the specific output terminal 101T has an output and the output terminal 101S has no output. The That is, it is confirmed that the input signal is output only from the specific output terminal 101T and there is no multiple output.

  When the voltage of the output terminal 101S is not 0V, it can be seen that the output is output to any one of the output terminals 101S in addition to the specific output terminal 101T (there are multiple outputs). Therefore, the output terminal is specified from the output terminal 101S as follows.

  First, the output terminal 101S is divided into a plurality of blocks, and the presence / absence of output is determined for each block using the output check device 1 as described above. Then, by further dividing a block whose voltage is not 0 V (determined as having an output) and repeating the determination of the presence / absence of an output, the terminals where the output signal is detected are narrowed down. In this way, when the terminals are squeezed, the voltage at each terminal is measured by the tester to identify the terminal. For the identified terminal, the cause of the multiplex output is identified and dealt with by confirming the wiring.

  Furthermore, when confirming the output for the other specific output terminal 101T, the specific output terminal 101T that has been confirmed to be separated from the wire 10 is connected to the wire 10 and another specific terminal to be confirmed next is confirmed. The output terminal 101T is moved away from the wire 10 and the output is confirmed as described above.

  As described above, according to the output confirmation method and the output confirmation device 1, it is only necessary to confirm the presence / absence of signal output at the specific output terminal 101 </ b> T and the presence / absence of signal output at the wire 10. The output can be checked efficiently, and the labor for checking the output can be greatly reduced. That is, since it is not necessary to connect a tester or the like to each output terminal 101 of the terminal board 100 for confirmation, labor and time required for confirmation of output can be reduced. For example, even if the terminal board 100 has 1000 output terminals 101, the presence / absence of output can be determined by one measurement if the output confirmation device 1 is applied. More specifically, as in this embodiment, when measuring a pulse signal as in this embodiment, the measurement of 1000 output terminals 101 conventionally requires 1000 seconds (1 second × 1000) even for the measurement time alone. Was. However, if the output check device 1 is applied, it is possible to determine whether or not there is an output for 1000 output terminals 101 in one measurement without changing the tester.

  In addition, the output confirmation apparatus 1 includes a plurality of connection / disconnection portions 12 that can be connected to and disconnected from the output terminal 101S corresponding to the arrangement positions of the output terminals 101, and an integrated wire 10 through which signals pass, and a wire It is possible to manufacture with only the testers T1 and T2 that confirm the presence / absence of a signal from the specific output terminal 101T to which the 10 connecting / disconnecting portions 12 are connected / disconnected, and the presence / absence of the signal from the wire 10. Since the wire 10 can be formed by simply bending it with the jig 200 as shown in FIG. 4, the processing is easy and the manufacturing cost can be reduced. Therefore, significant labor can be reduced without using an expensive device.

  In addition, the connection between the connection screw 102 of the terminal board 100 and the output confirmation device 1 only has to be brought into contact with the conductor portion 102a of the connection screw 102 as shown in FIG. It can be easily installed without the need for tools. For this reason, since the output can be confirmed using the output confirmation apparatus 1 without changing the existing terminal board 100 or the tester, the output confirmation apparatus 1 can be easily attached to all the existing terminal boards 100. Apply to check the output.

  Furthermore, even when the output is confirmed for a plurality of input signals, the output can be easily confirmed by simply changing the specific output terminal 101T to be separated from the wire 10 and measuring it.

  Although the embodiments of the present invention have been described above, the specific configuration is not limited to these embodiments, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, the output confirmation apparatus 1 may connect all the output terminals 101S in series, but the output terminal 101S may be divided into a plurality of blocks and output determination may be performed for each block. Further, as shown in FIG. 5, the connection between the output confirmation device 1 and the connection screw 102S is substantially along the outer periphery so that the inner side of the connection / disconnection portion 12 is in contact with the outer periphery of the conductor portion 102Sa of the connection screw 102S. You may make it make a half circle.

  Further, the signal conductor is not a single wire 10, but a thin plate-like signal conductor is cut into a comb shape having a base portion 21 and a tooth portion (connection / disconnection portion) 22 as shown in FIG. You may use the output confirmation apparatus 2 formed so that it might correspond to the arrangement | sequence space | interval of the terminal 101. FIG. The base portion 21 and the tooth portion 22 can be bent in any direction and can be deformed into an arbitrary shape. Here, the interval between the adjacent tooth portions 22 is formed at d2, which is substantially equal to the mounting interval d1 of the connection screw 102 of the adjacent output terminal 101. On the tip side of the tooth portion 22, a fitting portion 22 a that is recessed on an arc that fits and closely contacts the conductor portion 102 a of the connection screw 102 is formed. The signal conductor having such a shape is connected to the output terminal 101 by tightening the connection screw 102 in a state where the fitting portion 22a is in contact with the outer periphery of the conductor portion 102a. When the specific output terminal 101T is separated from the signal conductor, the tooth portion 22 corresponding to the specific output terminal 101T may be bent at a substantially right angle so as not to contact the conductor portion 102a.

  Furthermore, although the testers T1 and T2 have been described as the measuring devices in the confirmation of the output, any measurement other than the tester can be used as long as the presence or absence of a signal from the specific output terminal 101T and the presence or absence of the signal from the wire 10 can be confirmed. It may be a vessel. For example, a buzzer or a lamp may be used to emit sound or light when the voltage is not 0 V (when there is an output signal).

  Furthermore, the output confirmation device 1 can be used not only for confirming the output of a signal but also for a withstand voltage test of the terminal board 100. For example, as shown in FIG. 2, a withstand voltage test is performed by applying AC 2000 V for 1 minute between the output confirmation device 1 applied to the connection terminal 100 by applying the output confirmation device 1 and the ground bar 51 (between the charged portion and the ground). Can be implemented.
