JP5425569B2 - Detection notification system for branch lines - Google Patents

Description

  The present invention relates to a branch line detection and notification system that is useful when it is detected and notified that a detected body such as a shift has reached a predetermined height on a branch line provided on a columnar standing body such as a utility pole.

  There is an inconvenience that a ground fault occurs when vines such as frogs roll around the branch line of the power pole and come into contact with the distribution line. For this reason, in the past, when a periodic inspection was performed to check whether or not a vine plant was rolled up on a power pole branch line during regular inspections, or to check for the presence or absence of a roll, I was trying to cut down.

  Further, in order to prevent the curling up, for example, a fixing part that is attached to a power pole branch line obliquely installed between the power pole and the ground, and is wound spirally around the lower part or the middle part of the power pole branch line; And a guide portion that is continuously changed by a linear body from the upper end of the fixed portion to a vertical posture or a substantially vertical posture, and is further guided to the linear body in a direction away from the utility pole branch line. A vine plant roll-up prevention tool in which a portion is continuously provided at the tip of the guiding portion (see Patent Document 1), a pair of plate-like blades, and an upper end portion of the pair of blades. The utility pole branch line anti-spinning device is formed by the branch line installation tube, and the branch line installation cylinder can be opened and closed when passing through the utility pole branch line at the connection with the blades. What was made possible (Patent Document 2) Irradiation), and the like are also known.

  However, when using any of the above-described anti-roll-up tools, it is still necessary to rely on periodic inspections and temporary inspections in order to determine whether or not vines such as frogs require cutting. If we miss the discovery of the roll-up, it is expected that it will wind up to the distribution line beyond the roll-up prevention device, and there is a disadvantage that it is impossible to reliably grasp the vine plants to be cut.

  In order to avoid such inconveniences, periodic inspections and temporary inspections may be performed frequently, but there are many places where crawls, etc. are rolled up, and the growth is remarkably fast. In many cases, the situation at the time of patrol is completely different, and it is almost impossible to deal with all the places.

  The present invention has been made in view of such circumstances, and eliminates the need for judgment of the degree of growth (rolling degree) by visual inspection through periodic inspections and temporary inspections, and reliably identifies branch lines where cutting is necessary. The main issue is to provide a branch line detection and notification system that can respond quickly.

  That is, the branch line detection notification system according to the present invention is a contact sensor that is attached to a branch line of a columnar standing body and outputs a detection signal when the detected body comes into contact with the detection signal from the contact sensor. An information transmission device that transmits information along with information on a columnar standing body having a branch line to which a sensor is attached, and an alarm device that receives information from the information transmission device. When it is determined that the detection signal from the sensor is continuously output for a predetermined time or more, detection notification means for reporting in a predetermined format in association with the information of the columnar standing body, and output of the detection signal It is characterized by comprising report canceling means for canceling the report when it is determined that it has disappeared.

Therefore, when the detected object comes into contact with the contact sensor attached to the branch line, a detection signal is output from the contact sensor, and the information transmission apparatus uses this detection signal as a columnar standing body having a branch line to which the contact sensor is attached. The information is sent to the alarm device. When the alarm device receives the information from the detection notification device, the alarm device determines that the received detection signal is continuously output for a predetermined time or more and associates it with the information of the columnar standing body in a predetermined format. Therefore, the worker can remotely recognize that the detected object has touched the contact sensor, and can grasp that the work for releasing the contact state is necessary. .
Further, since the notification is not canceled unless the contact state between the detected object and the contact sensor is canceled, the removal work of the detected object is not forgotten.

  Here, as a specific configuration of the detection notification device, the information is received from the information transmission device when it is determined that the detection notification device has a display unit and the detection signal is continuously output for a predetermined time or more. You may display on the said display part including the information of the said columnar standing body in order. In the case where a speaker is provided, an alarm sound may be output when it is determined that the detection signal is continuously output for a predetermined time or more.

  Further, the contact sensor may be a sheet having a bottom opened, even if it is in the form of a sheet wound around a predetermined height position of the branch line or a cylindrical shape that passes through the branch line at a predetermined height position. Further, the axial line may be substantially aligned with the extending direction of the branch line, and the open side may be attached downward, and the contact sensor element may be provided on the inner peripheral surface.

  According to the former configuration, it is effective to detect that a vine plant such as a prank rolled up on a branch line has reached a predetermined height, and in the latter case, the contact sensor element is located inside the cone. Since it is arranged, it is possible to avoid contact with the rain, and to catch the detected object (such as shifting up the branch line) that approaches from below, and to avoid a malfunction due to the rain or the like.

  As described above, according to the branch line detection reporting system according to the present invention, the contact sensor is attached to the branch line of the columnar standing body, and the detection information output when the detected body contacts the contact sensor is columnar. When it is determined that the detection information has been received continuously for a predetermined time or more based on the transmitted information, it is associated with the columnar standing body information in a predetermined format. Therefore, even when vines such as frogs grow upward along the branch line, it is possible to remotely detect whether or not there is a request for logging, and the growth of frogs by visual inspection through periodic inspections and temporary patrols It is not necessary to determine the degree (rolling degree), and it is possible to identify the branch line where logging is necessary, and to respond quickly.

For this reason, in the periodic inspection, it is possible to concentrate on the original inspection work, and it is not necessary to entrust temporary inspection, so it is possible to reduce the commission cost.
In addition, unless the object to be detected is removed and contact with the contact sensor is lost, the alarm device will continue to issue a report, so that the object to be detected will not be forgotten and the object to be detected will contact the distribution line. It becomes possible to prevent the ground fault accident due to.

  Embodiments of a branch line detection notification system according to the present invention will be described below with reference to the accompanying drawings.

  In FIG. 1, the schematic diagram which shows the structural example of the detection notification system for branch lines which concerns on this invention is shown. This branch line detection and notification system is provided for each branch line 2 of the utility pole 1 provided in the growing area of the kazura 20, and provided for each contact sensor 3. Etc., and an information transmission device 4 fixed to the network.

The contact sensor 3 is, for example, as shown in FIG. 2, for example, a sheet-like pressure sensor (shown by (a)) wound around the branch line 2, or a cylindrical feeling through which the branch line 2 is inserted. A pressure sensor (shown by (b)) is configured to output a detection signal when the outer surface is touched by a shift that is a detected object. The contact sensor 3 is provided at a position where the height from the ground is about 4 m, and is attached so as not to be displaced over a range of about 1 m in the axial direction of the branch line 2.
The method of attaching the contact sensor 3 to the branch line 2 is not particularly limited. For example, if the contact sensor is a sheet, a magic tape (registered trademark) is used so as not to interfere with the sensor element while being wound around the branch line 2. ) Or by providing a fastener for fixing to the branch line at the lower end of the contact sensor so that the contact sensor does not shift downward. If the contact sensor is cylindrical, a slit that can be opened and closed along the axial direction is formed, the inner diameter is smaller than the diameter of the branch line, the slit is opened, and the branch line is fitted inside. The inner peripheral surface may be pressed against the branch line, or may be fixed by screwing a tightening bolt in the radial direction from the outside with the branch line inserted inward.

  The information transmission device 4 is connected to an alarm device 9 provided in a monitoring station 8 such as a sales office via a remote transmission line network 10, and when a detection signal from the contact sensor 3 is input, the detection signal is generated. The information is transmitted to the alarm device 9 together with information (for example, a utility pole number) of the utility pole 1 having the branch line 2 to which the contact sensor 3 is attached.

  The alarm device 9 includes functions necessary as an information processing device (a communication processing unit, a storage unit, a display unit 9a such as a monitor, an input unit such as a keyboard), and a database 11 that stores various data necessary for each process. It has. The database 11 includes a history database 12 that stores history information of contact of the contact 20 with the touch sensor 3 and a map database 13 that stores map data including arrangement information of each power pole 1. As shown in FIG. 3, the data stored in the database 12 includes the time at which the contact 20 is brought into contact with the contact sensor 3 and the detection signal is generated (the signal generation time), and whether the contact sensor 3 is in contact. The time (signal release time) at which the generation of the detection signal from the contact sensor 3 is canceled after 20 is removed is stored in association with the telephone pole number.

  The alarm device 9 includes a detection notification means and a notification release means in addition to the functions necessary for the information processing apparatus. In the following, these means will be described, but in actuality, they are implemented by cooperation with hardware resources by a predetermined program that is resident.

  The detection notification means is a means for making a notification in a predetermined format in association with the power pole information (electric pole number) when it is determined that the detection signal from the contact sensor 3 is continuously output for a predetermined time or more. In this example, when it is determined that the detection signal is continuously output for a predetermined time or more, the telephone pole numbers (column-like standing bodies shown in FIG. Information), signal generation time, and the like are displayed in a list on the display unit 9a as shown in FIG. When the alarm device 9 includes a speaker, an alarm sound may be output when it is determined that the detection signal is continuously output for a predetermined time or more.

  The notification cancellation means is a means for canceling the notification when it is determined that the output of the detection signal from the contact sensor 3 has disappeared. In this example, when it is determined that the output of the detection signal has disappeared The signal release time is displayed at the location of the corresponding utility pole number.

In FIG. 4, an example of the operation process of the branch line detection notification system according to the present invention is shown as a flowchart, and an example of the operation process of the system will be described below based on this flowchart.
In addition, the processing example shown here supplies a control program that can be read by the alarm device 9 via a storage medium such as a ROM chip or a CD-ROM, or distributes it via a network, etc. Is installed in the alarm device 9 and this installed control program is executed.

  First, after operating this device, the alarm device 9 monitors the presence or absence of information transmission from the information transmission device 4 through an initial setting (not shown). That is, a detection signal is generated from the contact sensor 3, and information generation information of the detection signal and information (electric pole number) of the utility pole 1 including the branch line 2 to which the contact sensor 3 is attached are transmitted from the information transmission device 4. If yes, the information is allowed to be taken in (step S02), and it is determined whether or not the information is taken in (step S04).

  As a result, if it is determined that there is no captured information, it is determined whether or not there is a utility pole that has received the detection signal generation information until now, but the generation information of the detection signal has disappeared (step) S06). If it is determined that there is a utility pole whose detection signal generation information has disappeared, the signal release time is recorded in the history database 12 for the corresponding utility pole data (step S08), and the detection signal generation information is stored. If it is determined that there is no lost utility pole, the process of step S02 for capturing the information is repeated. At the initial stage when no detection signal is generated, there is no utility pole from which the generation information of the detection signal is lost (because there is no utility pole that has previously generated the detection signal), so the processes of steps S02 to S06 are repeated.

  In step S04, if it is determined that there is captured information, it is determined whether there is telephone pole information not recorded in the history database 12 (step S10). If not, step S06 is performed. If the subsequent processing is performed, the corresponding contact sensor 3 is identified from the utility pole information not recorded in the history database 12 (step S12).

  Then, it is determined whether or not the detection signal from the specified contact sensor 3 continues for a predetermined time or more (step S14). During this predetermined time, when the kazura is temporarily in contact, when a foreign object other than kazura is temporarily in contact, when the rain hits the contact sensor, etc., the kazura rolls up and continuously contacts the contact sensor 3. When the detection signal is less than the predetermined time, the process after step S02 is repeated, and it is determined that the contact state continues for a predetermined time or more. In the case where it is detected, the utility pole information and the signal generation time are recorded in the history database 12 to update the data (step S16).

  Thereafter, based on the data in the history database 12, the history information of the utility poles for which there is a request for felling felling (information on the presence or absence of continuous contact with the missing contact sensor 3), for example, in the order of detection as shown in FIG. This is displayed on the display unit 9a (step S18).

  This display is performed when there is a request to switch the display format to a format for displaying the distribution of miscellaneous requests for logging by pressing a switch button (not shown) (step S20) or until a predetermined time elapses. (Step S22) When the predetermined time has elapsed, the processing after Step S02 is performed again. When there is a request for switching the display format within the predetermined time, for example, as shown in FIG. , The distribution of miscellaneous requests for felling (distribution of utility poles with branch lines winding up the kazura) is superimposed on the map data in the map database 13 and the pole positions obtained based on the utility pole information (electric pole number) are displayed. It is displayed on the part 9a (step S24).

  This distribution is also displayed when there is a request to switch to a format in which history information of utility poles with a request for cutting felling is displayed in the order of detection by pressing a changeover switch (not shown) (step S26) or set in advance. The process is performed until a predetermined time elapses (step S28), and when there is a request for switching the display format within the predetermined time, the history information having the contents as shown in FIG. 3 is again displayed on the display unit 9a ( Step S16).

  In the above configuration, when the displacement 20 rolls up on the branch line 2 of a certain utility pole 1 and comes into contact with the contact sensor 3, a detection signal is output from the contact sensor 3, and the signal is attached to the utility pole. Is input. Then, when the information transmission device 4 transmits the detection signal generation information to the alarm device 9 of the monitoring station 8 together with the information (electric pole number) of the utility pole 1 provided with the branch line 2, and the contact state continues for a predetermined time or more. The contact information is displayed on the display unit 9a in association with the information on the utility pole in which the skirt 20 is in contact with the contact sensor 3.

  Therefore, as shown in FIG. 6, the pole 20 that is in contact with the contact sensor 3, that is, the position of the pole that needs to be cut down because it has been rolled up to a predetermined height of the branch line is remotely grasped. Therefore, it is not necessary to judge the degree of growth (rolling degree) by regular inspections and visual inspections of temporary inspections, and it is possible to identify and quickly respond to the branch line where logging is necessary without missing it. It becomes possible.

  For this reason, in the periodic inspection, it is possible to concentrate on the original inspection work, and it becomes unnecessary to entrust the temporary inspection, so it is possible to reduce the commission cost. In addition, the alarm device 9 will continue to generate an alarm unless the kazura is cut down and the contact with the contact sensor 3 is removed, so that it is possible to prevent the forgetting to remove the kazura and prevent a ground fault accident due to the kazura. It becomes.

  FIG. 7 shows another configuration example of the contact sensor 3. The contact sensor 3 includes an umbrella portion 3a formed in a conical shape with an open bottom, the axis of the umbrella portion 3a is substantially aligned with the extending direction of the branch line 2, and the opened side is directed downward. The shift 20 that is attached to the branch line 2 and is rolled up from below can be received inside the contact sensor 3. Further, a contact sensor element 3b composed of a pressure-sensitive element or the like is attached to the inner peripheral surface of the umbrella part 3a, and when the skirt 20 contacts the inner peripheral surface of the umbrella part 3a, the information transmitting device 4 is The detection signal is output. In addition, in this example, although the umbrella part 3a is formed in the cone, the cone of another shape may be sufficient. Other configurations are the same as those in the above configuration example.

  In such a configuration, the winding of the displacement 20 is temporarily received by the umbrella portion 3a of the contact sensor 3, and is prevented from being rolled up above the contact sensor 3, and the displacement is in contact with the inner peripheral surface. Since the detection signal is transmitted at that time, even if the removal of the shift 20 is delayed, further winding up to the branch line can be suppressed and the removal of the shift can be surely promoted. Further, according to the contact sensor 3 of this example, since the open part of the cone is directed downward, the rain does not directly hit the contact sensor element 3b, and there is a risk of erroneous detection due to rain or sensor deterioration due to rain. It becomes possible to prevent.

  In the above-described example, the configuration example in which the contact sensor 3 and the information transmission device 4 are separated is shown. However, the contact sensor 3 and the information transmission device 4 may be integrated. In the above example, various information is transmitted from the information transmission device 4 to the alarm device 9 via a dedicated line. However, as indicated by the broken line in FIG. 1, various information is transmitted wirelessly. Also good.
