Description

  The present invention replaces a transmitter (beacon) constituting a system for grasping the position of a walking body or a moving body using a communication function of a portable terminal in a restricted space such as the inside of a building. It is related to effective technology applied to support.

When a fire brigade enters a building due to a fire, etc., and fire extinguishing and rescue activities (hereinafter referred to as fire fighting), the command team located outside is in the building and the location information of the crew in the building. Need to be as accurate as possible.
Conventionally, various inventions related to a positioning system for detecting the position of a moving body such as a walking body or a vehicle such as an operator have been proposed, and one of them is a position using, for example, GPS (Global Positioning System). There is a way to get information.

  However, the position information acquisition method using GPS together cannot acquire the position of an operator who works indoors where GPS radio waves do not reach. In addition, only the positioning method using a gyro sensor, an acceleration sensor, or the like has a problem that an error increases as observation is continued. Therefore, the applicant can use a beacon to quickly and accurately grasp the position when an operator moves within a restricted space such as the inside of a building, thereby shortening the time. An invention relating to a position estimation method and system capable of completing work and mission has been filed (Patent Document 1).

JP 2006-206016 A JP 2007-124406 A JP 2016-38895 A

  When the position estimation method disclosed in Patent Literature 1 is applied, it is necessary to install a plurality of beacons in the building in advance. Furthermore, when there is a beacon that is out of order or has a battery exhausted, it is necessary to quickly replace it with a normal beacon. However, since the beacon has a relatively narrow range of radio waves, the number of beacons installed in one monitoring area increases, and there may be a situation in which multiple beacons in the same area are exchanged at the same time. In such a case, it has become clear that there is a problem that an operator may accidentally exchange a normal beacon.

Specifically, when exchanging a beacon with an abnormality, the worker confirms the position of the beacon where the abnormality is detected from the beacon installation map (map) of each facility managed by the server, and the normal beacon. Then, the ID (identification information) of the newly installed beacon is registered in the server in relation to the installation position information.
However, in a facility where a large number of beacons are installed, it is difficult to specify the position of the abnormal beacon from the installation map (map), and an operation error that erroneously replaces the beacon with no abnormality occurs. There is a fear. If a new beacon is registered without noticing the replacement error, the installation drawing and the actual layout cannot be matched, and the facility that operates the position estimation system cannot grasp the correct position. End up.

In addition, the invention regarding the position confirmation apparatus which monitors the position of the worker who moves the inside of a building, and the invention regarding the object person discovery support system which discovers an object person using a beacon are proposed (patent documents 2 and 3).
Among these, the invention described in Patent Document 2 installs a wireless LAN base station in a monitoring area, transmits the radio field strength information of each base station measured by the terminal to the server via the base station, and receives the server. The distance between each base station and the terminal is estimated from the received radio field strength information and the approximate curve indicating the radio characteristics of each base station, the terminal position is detected, and the detected terminal position is distributed and displayed. .

Here, since the radio base station generally operates with a power source supplied from the outside, the system of Patent Document 2 does not replace the battery due to battery exhaustion. In addition, since the intensity of radio waves transmitted from the wireless base station is higher than that of beacons, the number of base stations installed in one area is not as large as that of beacons, so that there is little risk of erroneous replacement when a failure occurs.
On the other hand, the invention described in Patent Document 3 is a system for discovering a target person using a beacon that operates on a battery, but the monitoring target area is outdoors and the beacon is installed outdoors. Since the locations are far from each other and the installation environment is greatly different, there is little risk of erroneous replacement in the event of a failure.

  The present invention has been made paying attention to the problems as described above, and the object of the present invention is that when a plurality of transmitters (beacons) are installed in a predetermined area such as the inside of a building, An object of the present invention is to provide a transmitter exchanging work support system capable of exchanging a transmitter with a battery exhausted with a new transmitter in a short time without error.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a transmitter replacement work support system according to the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 shows an outline of a first embodiment of a transmitter (beacon) replacement work support system (hereinafter simply referred to as a replacement work support system) according to the present invention. As shown in FIG. 1, in the replacement work support system of the present embodiment, signals (radio waves) can be received from beacon transmitters 10 arranged at a plurality of locations in a predetermined area inside the building. Management server (computer device) 40 as a data processing device that performs data communication between the mobile terminal 20 and the mobile terminal 20 via the communication network 30, and installation position information (installation) of the transmitter 10 in a facility that is a monitoring area The database 50 etc. in which the figure) etc. were stored are comprised.

  As a communication method of the transmitter 10 for transmitting a beacon wireless signal (device ID, facility information and other unique information) to the mobile terminal 20, for example, Bluetooth (registered trademark) communication, WiFi according to the IEEE 802.11 standard, or the like. A known communication method such as wireless LAN or infrared communication can be used. The interval at which the transmitters 10 are arranged is not particularly limited. In the following description, it is assumed that the transmitters 10 are arranged at a distance such that the communication ranges of adjacent transmitters overlap each other.

Specifically, since fire detectors and sprinkler heads are originally installed at predetermined intervals in the building, beacons attached in a form that is built in or added to those devices can be used.
The transmitter 10 includes a built-in battery as a power source and a transmitter that periodically transmits its identification information on a radio signal to the surroundings. The information transmitted by the transmitter 10 wirelessly only needs to include at least the identification code of the transmitter, and may further include information related to the installed area.

  On the other hand, the portable terminal 20 is a device such as a smartphone having a function of receiving a signal from the transmitter 10 and a wireless communication function, and an operator who performs inspection and replacement moves together. The mobile terminal 20 periodically receives a beacon signal transmitted wirelessly from the transmitter 10, extracts information contained in the beacon signal transmitted from the transmitter 10, detects the received radio wave intensity, It can be a condition that an application program for work support for executing processing for transmitting information and radio wave intensity to the management server 40 via the communication network 30 is stored.

  The management server 40 is newly installed in the beacon information processing unit 41 that processes information of the transmitter 10 (hereinafter referred to as a beacon) received from the mobile terminal 20 or the installed position information table of the database 50 from the replaced abnormal beacon. A beacon registration processing unit 42 that updates and registers an ID (identification code) in the beacon is provided. In addition, the management server 40 has a function of transmitting a warning to the portable terminal 20 when an operator mistakenly replaces a normal beacon or when it is mistakenly exchanged. The beacon registration processing unit 42 may leave or delete the ID (identification code) of the exchanged abnormal beacon as a history when performing beacon update registration in the installation position information table of the database 50. You may do it.

In the replacement work support system of the present embodiment, the management server 40 estimates the status of replacement work by the worker based on the ID of the beacon acquired from the mobile terminal 20 and the received radio wave intensity, and performs appropriate processing according to the situation. Is to execute.
First, the concept of the replacement work status estimation in this embodiment will be described with reference to FIGS. In addition, as an action when an operator performs beacon replacement work, there are a case where a worker works while carrying a plurality of beacons, and a case where a worker works by carrying beacons one by one. Hereinafter, the replacement work procedure will be described for each case.

For example, as shown in FIG. 2, in an area where nine beacons # 1 to # 9 are installed, two beacons # 2 and # 9 are out of order or the battery is exhausted, Carry beacons #A and #B, first move to the installation location of beacon # 2 as shown in FIG. 2 (A), exchange beacons # 2 and #A, and then as shown in FIG. 2 (C). A case will be described in which the beacon # 9 is moved to the installation location and the beacons # 9 and #B are exchanged.
In this system, the area map that reflects the installation location information of the registered transmitters 10 (# 1 to # 9) is operated as a normal operation mode, and # 2 and # 9 are detected as exchange target candidates during normal operation. When these replacement operations are performed, the normal operation mode is changed to the replacement operation mode manually or automatically, and other transmitters #A and #B that are not registered are also displayed on the area map in the replacement operation mode. It is assumed that it is displayed on. Regardless of the mode, the transmitter information received by the mobile terminal may always be displayed on the area map.

  In the above case, considering the case where the new beacon is correctly installed in the above procedure, the radio wave intensity of the signal received by the portable terminal 20 held by the worker from the new beacons #A and #B is shown in FIG. In (A), it should change as indicated by a solid line (a line connecting ▲ marks) and a broken line (a line connecting □ marks). In FIG. 3A, t1 is the timing at which the installation location of beacon # 2 is reached, and t2 is the timing at which the installation location of beacon # 9 is reached.

Therefore, if the received radio wave intensities of the new beacons #A and #B do not change as indicated by the solid line in FIG. 3A, it can be determined that there has been an incorrect installation. Moreover, even if the installation order of the new beacons #A and #B is correct, if the beacons other than the existing beacons # 2 and # 9 are accidentally removed, the received radio waves from the beacons that are accidentally removed are received. As indicated by a dotted line C in FIG. 3A, the strength increases immediately before the replacement timing, and the high state continues until after the work is completed, so that it can be determined that there has been an erroneous replacement.
In this description, the example in which the installation order of the new beacons #A and #B is determined and the replacement work is correctly determined is shown. However, #A is installed next to #B. Even in this case, in the case where the change in the radio field intensity is switched between #A and #B in FIG. 3 (FIG. 5), even if it is determined that the exchange is performed from # 2 to #B and from # 9 to #A. good.

  Next, in a situation similar to the above (when # 2 and # 9 are out of order), the worker first moves to the installation location of beacon # 2 as shown in FIG. After exchanging # 2 and #A, take beacon # 2 and return to the starting point as shown in FIG. 4 (B), and beacon #B as shown in FIG. 4 (C). A case will be described in which the beacon # 9 and #B are exchanged.

  In this case, considering the case where the new beacon is correctly installed in the above procedure, the mobile terminal 20 held by the worker is moved away from the beacon after the replacement work. The radio wave intensity of the signal received from B should change as shown by a solid line (a line connecting ▲ marks) and a broken line (a line connecting □ marks) in FIG. In FIG. 5A, t1 is the timing at which the installation location of beacon # 2 is reached, and t2 is the timing at which the installation location of beacon # 9 is reached.

Therefore, if the received radio wave intensities of the new beacons #A and #B do not change as indicated by the solid line and the broken line shown in FIG. 5A, it can be determined that there is an incorrect installation. Moreover, even if the installation order of the new beacons #A and #B is correct, if the beacons other than the existing beacons # 2 and # 9 are accidentally removed, the received radio waves from the beacons that are accidentally removed are received. Similar to the dotted line C in FIG. 3A, the strength increases immediately before the replacement timing, and the high state continues until after the work is completed, so that it can be determined that there has been an erroneous replacement.
In this description, the example in which the installation order of the new beacons #A and #B is determined and the replacement work is correctly determined is shown. However, #A is installed next to #B. Even in this case, in the case where the change in the radio field intensity is switched between #A and #B in FIG. 3 (FIG. 5), even if it is determined that the exchange is performed from # 2 to #B and from # 9 to #A. good.

  Next, a processing procedure by the management server 40 configuring the exchange work support system of the present embodiment will be described using the flowchart shown in FIG. Before the process according to the flowchart of FIG. 6 is started, the ID of the existing failure beacon where a failure or the like is detected and the ID of a new beacon exchanged with these beacons are registered in the management server 40. It shall be. Further, it is assumed that an application program for work support stored in the mobile terminal 20 is started before the work starts.

  When the replacement work support program is started, the management server 40 first reads a table describing the beacon installation position and the beacon ID in the work target facility from the database 50 as shown in FIG. 6 (step S1). . Next, beacon information from each portable terminal 20 is received (step S2), and a reception history information list in which the received beacon information is recorded together with the reception time is created and stored in the memory (step S3). Thereafter, the reception information for a predetermined time (for example, 15 minutes) is totaled for each beacon, and the work position is estimated at any time (step S4).

Specifically, paying attention to the new beacon #A, the timing t1 at which the received radio wave intensity from the beacon #A begins to decrease as shown by the solid line in FIG. Yes, the received radio wave intensity of the surrounding beacons (# 1, # 3, # 5 in FIG. 2) at that time should be almost the same level as shown in FIG. If it is a reception level like B), it can be estimated that it was working in the installation position of failure beacon # 2. When exchanging beacon # 9, the received radio wave intensity of neighboring beacons (# 5, # 6, # 8 in FIG. 2) at the end of the work is almost the same level as shown in FIG. Therefore, if the reception level is as shown in FIG. 3C, it can be estimated that the work was performed at the installation position of the failure beacon # 9.
The management server 40 determines whether or not the position of the beacon exchanged from the estimated position in step S4 is correct (step S5). If it is determined that the position of the exchanged beacon is correct (Yes), the process proceeds to step S6, and the ID (#A, #B) of the newly established beacon is updated and registered in the beacon installation position information table. Once update registration has been performed, the process advances to step S7 to determine whether or not the work has been completed.

  If it is determined in step S5 that the position of the exchanged beacon is not correct (No), the process proceeds to step S7, and it is determined whether the work is completed. The end of the work can be determined, for example, based on whether or not the received radio wave intensities of the new beacons #A and #B are below a predetermined level. Alternatively, the application program stored in the mobile terminal 20 may display the “work end” button, and may be determined as “work end” when the button is operated.

  If it is determined in step S7 that the work is not completed (No), the process returns to step S2 and the above process is repeated. If it is determined in step S7 that the work has been completed (Yes), the process proceeds to step S8 to determine whether or not an unreplaced fault beacon remains. If it is determined in step S8 that an unreplaced fault beacon remains (Yes), the process proceeds to step S9, for example, the map data of the facility is read from the database 50, and the position of the unreplaced fault beacon is described. A facility map (map) is created and transmitted to the mobile terminal 20, and the process returns to step S2.

On the other hand, if it is determined in step S8 that no unreplaced fault beacon remains (No), the process proceeds to step S10, the beacon installation position information table rewritten in step S6 is registered in the database 50, and the series of processing ends. .
In the exchange work support system in the present embodiment, the server 40 executes the above-described process to monitor whether or not the work for exchanging a failed beacon with a new beacon is correctly performed, and performs the correct exchange work. Can help.

(Second embodiment)
FIG. 7 shows a processing procedure of the server in the second embodiment of the beacon exchange work support system according to the present invention. The configuration of the replacement work support system in the present embodiment may be the same as that shown in FIG.
In the present embodiment, the server 40 warns when an operator mistakenly detects that a new beacon is being exchanged for a normal beacon rather than a malfunctioning beacon. By the way, when a worker exchanges a beacon, he climbs on a stepladder and works at a high place, so if the beacon to be exchanged is normal, the received radio wave intensity from that beacon is the radio wave during normal movement. Since it becomes higher than the strength, the mobile terminal 20 transmits the ID and the radio wave strength received from the beacon 10 to the server 40, and the server 40 determines whether or not the exchange is wrong by referring to the information (failure list) in the database. can do.

  The flowchart of FIG. 7 showing the procedure of this embodiment is almost the same as the flowchart of FIG. The difference is that between steps S4 and S5, step S11 for determining whether a beacon that has not failed by mistake has been approached, and if it has been determined that an erroneous beacon has been approached, Step S12 for transmitting a “warning” and step S13 for determining whether or not an exchange beacon is attached are provided. Further, in this embodiment, it is determined whether or not the replacement position is correct in step S5. If it is determined that the replacement position is not correct (No), a warning is transmitted to the mobile terminal in step S13, and then the area map in step S9. This is also different in that the process returns to step S2 after the creation and transmission. Further, in the present embodiment, it is determined whether or not all work has been completed in step S7, and when it is determined that all work has been completed (Yes) or when it is determined (No) in added step S13. After the area map is created and transmitted in step S9, the process returns to step S2.

When the mobile terminal 20 receives a “warning” from the server 40 by the process of step S13, the mobile terminal 20 can notify an operator of an erroneous operation by generating an alarm sound or the like. As a result, erroneous beacon exchange can be avoided.
In addition, when transmitting a “warning” to the mobile terminal 20, a facility map describing the location of the failure beacon may be transmitted. However, in this second embodiment, it is possible to know an erroneous operation in the middle of the operation. You may abbreviate | omit transmission of the facility map which described the position of the unreplaced failure beacon of step S9.

(Modification)
FIG. 8 shows a processing procedure of the server in the first modification of the beacon exchange work support system according to the present invention.
In this modified example, if you notice that you have replaced a normal beacon by mistake after the end of the work, you can skip the work of installing the replaced beacon in its original position again. The beacon can be exchanged for a normal beacon.

  The flowchart of FIG. 8 showing the procedure of this modification is almost the same as the flowchart of FIG. The difference is that instead of determining whether or not the position of the exchanged beacon is correct in step S5, it is determined whether or not the exchange of the beacon is simply performed, and in step S6, the beacon installation position information table is exchanged. The original beacon ID is deleted, and the newly established beacon ID is written. The exchange of the normal beacon can be determined from the fact that the radio wave intensity of the new beacon gradually decreases, while the radio wave intensity of the removed normal beacon maintains a high level.

According to this modification, even if a normal beacon is exchanged by mistake, if the work to replace the removed beacon with a failed beacon is performed, the beacon installation position information table is rewritten at that time. Therefore, there is no problem in the position estimation system.
In addition, when you notice that it has been accidentally replaced, you can attach the removed normal beacon to the location of the broken beacon, eliminating the need for redo work and improving the overall work efficiency There is.

Next, a second modification of the beacon exchange work support system according to the present invention will be described.
This modification assumes that the beacon that is carried to be exchanged has an initial failure. Here, as the “initial failure”, for example, (a) the beacon radio wave intensity is not normal but is emitted (low output), or (b) the power is not turned on (still in the OFF state). is there.

  For example, when the beacon #A has an initial failure, if it is “low output state” in (a), the beacon #A is displayed on the area map as in FIG. The radio wave intensity transitions at a low level as shown by a dotted line a in FIG. Therefore, the management server 40 receives the new beacon #A while calculating and displaying the movement trajectory of the worker (mobile terminal) from the radio field intensity of the beacons # 1, # 3 to # 6, and # 8 in the area. When the radio wave intensity does not exceed a predetermined level (when transitioning in a low state), it is determined as an initial failure and “error” is displayed on the monitor.

  On the other hand, if the beacon #A is “b) (the power is not turned on (still off)”, as shown in FIG. 9, the new beacon #A is not displayed on the area map, and only the portable terminal of the worker is displayed. And the received radio wave intensity from beacon #A remains “0”. Therefore, if the received radio wave intensity of the new beacon #A remains “0” even if the worker (mobile terminal) moves, the management server 40 determines that the initial failure is “error”. Display on the monitor.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, it can change suitably. For example, in the above-described embodiment, it has been described that the processing illustrated in FIG. 6, FIG. 7, or FIG. 8 is executed in the server 40, but the processing illustrated in FIG. 6, FIG. Before the start of work, the beacon installation position information of the facility to be worked is transmitted from the server 40 to the portable terminal 20, and the process shown in FIG. 6, FIG. 7, or FIG. 8 is performed on the portable terminal 20 side. You may make it perform.

In the above embodiment, the beacon has been described as having only a function of transmitting information. However, the beacon has a function of receiving a radio signal from a mobile terminal and a function of transmitting received information to a server. May be.
Furthermore, in the above embodiment, the case where the present invention is applied to a system that supports the work of exchanging a failed beacon with a new beacon has been described. However, the present invention involves the work of replacing the battery of a beacon that has run out of battery. It can also be used for supporting systems.
