Description

  The present invention relates to a user position display system that displays the position of a user in a hospital or the like.

  Conventionally, patients and care recipients (hereinafter simply referred to as patients) have been in specific rooms in hospitals and care facilities, but rarely have been left behind in a sick room. On the other hand, nurses and caregivers (hereinafter simply referred to as health care workers) have to search for deaf persons so that they are not at risk.

By the way, RFID (Radio Frequency)
There is known a technique for notifying an alarm that a patient has approached a monitoring area when the tag ID transmitted by the RFID tag is received by a wireless receiver that receives the tag ID in a specific area (for example, an IDentification) tag (for example, Patent Document 1).
Japanese Patent Laid-Open No. 2005-215961

In addition, a technique is known in which a current position and a movement locus of a mobile terminal possessed by a user are combined on map data and displayed on a display (for example, Patent Document 2).
JP-A-8-248115

  However, in the technique described in Patent Document 2 described above, when a trajectory is displayed in a building such as a hospital, all the trajectories are displayed even when the user passes the same place many times. There is a problem that it is difficult for medical staff to see the display screen. In addition, since the trajectory is displayed even when the deaf person returns to his / her room, there is a problem that it is difficult for the medical staff to determine whether or not he / she should be searched.

  The present invention has been made to solve such problems, and it is an object of the present invention to make it easy to see the trajectory of the deaf person while clarifying the deaf person to be searched when displaying the trajectory of the deaf person. And

  In order to solve the above-described problem, in the present invention, a current position of an IC tag is received by a plurality of receivers arranged at a predetermined position, and a deaf person (IC tag) is obtained from position information of the receiver that has received the current position. Get the trajectory of movement. At this time, when the current position of the IC tag is received again by the same receiver, it is displayed excluding the locus up to where it was received again.

  According to another aspect of the present invention, the same receiver is installed in the vicinity of the user's room.

  According to another aspect of the present invention, the current position of the IC tag is received by a plurality of receivers arranged at a predetermined position, and the user (IC tag) is determined by the received time information and the position information of each receiver. ) Is acquired. At this time, only the trajectory of movement from a predetermined time before to the current time is displayed.

  According to the present invention configured as described above, when the user passes through the same place, the trajectory of the previous movement is not displayed, so that a simple display can be performed. Therefore, the medical staff can easily see the display screen. Further, according to another aspect of the present invention, when the deaf person returns to his / her room, since the trajectory up to that point is not displayed, a simple display can be performed and the deferred person who has returned to the sickroom can move. The trajectory disappears. Therefore, the medical staff can easily see the display screen and can easily determine whether or not he is a searcher. In addition, according to another aspect of the present invention, since only the trajectory of movement within a predetermined time is displayed, a simple display can be performed. Therefore, the medical staff can easily see the display screen.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a deaf position display system according to the present embodiment. As shown in FIG. 1, the user position display system according to the present embodiment includes a first receiver, a second receiver, a third receiver,..., An Nth receiver (N is a natural number of 1 or more). N receivers, an IC tag 10 and a management device 11. The management device 11 includes a control unit 12, an interface 13, a storage unit 14, and a display unit 15.

  In FIG. 1, N receivers 1 to N are installed at a predetermined position in the hospital (for example, near the entrance / exit of each hospital room) and are connected to the management apparatus 11 via a transmission line. In the present embodiment, as shown in FIG. 2, the first receiver 1 is installed near the entrance / exit of the first room. The second receiver 2 is installed near the entrance / exit of the second room. The third receiver 3 is installed near the entrance / exit of the third room. A fourth receiver 4 not shown in FIG. 1 is installed in the vicinity of the entrance / exit of the fourth room. A fifth receiver 5 not shown in FIG. 1 is installed in the vicinity of the entrance / exit of the fifth room.

  The N receivers 1 to N receive the identification information of the IC tag when the IC tag approaches, and transmit the identification information of the receiver to the management device 11 together with the identification information of the IC tag.

  The IC tag 10 is configured by a non-contact RFID tag or the like and is carried by a patient. The IC tag 10 stores individual identification information that is different for each patient, and is read by an approaching receiver.

  The management device 11 is a device for managing a deaf person and is installed in a nurse center or the like where a medical worker is resident. The control unit 12 controls each component of the management device 11. The interface 13 receives the identification information of the IC tag and the identification information of the receiver received by the N receivers 1 to N. The storage unit 14 stores the identification information of the IC tag and the identification information of the patient (for example, the name of the patient) in association with each other. The storage unit 14 stores the identification information of the receiver and the position information in association with each other. The storage unit 14 stores a layout in the hospital.

  The display unit 15 displays a screen in which the trajectory of the movement of the user is superimposed on the layout stored in the storage unit 14.

  Next, a specific display example of the trajectory of the deaf person's movement will be described. When the first receiver 1 to the fifth receiver 5 are arranged as shown in FIG. 2, after Mr. A goes out from the second room, which is his hospital room, toward the first room, the second room direction Suppose you are in the direction of Room 3. The identification information of the IC tag 10 possessed by Mr. A is read by the second receiver 2 and then read by the first receiver 1, the second receiver 2, and the third receiver 3. The control unit 12 reads the patient identification information associated with the identification information of the IC tag 10 from the storage unit 14 and specifies that the deaf person is Mr. A.

  In addition, since the movement path of Mr. A is from the second room → the first room → the second room → the third room, the control unit 12 causes the second receiver 2 disposed in the vicinity of the second room to be connected to the IC tag 10 for the second time. The display screen as shown in FIG. 3 is displayed on the display unit 15 by superimposing the trajectory from room 2 to room 3 on the hospital layout screen, except for the trajectory up to the reception of the identification information.

  In the present embodiment, when the same receiver receives the identification information of the IC tag 10 again, the information is displayed excluding the locus up to that point. However, the present invention is not limited to this. For example, when the receiver arranged in the vicinity of the patient's room receives the identification information of the IC tag 10 again, it may be displayed excluding the locus up to that point. At this time, when the deaf person returns to his / her room, the trajectory of movement is not displayed.

  As described above in detail, according to the present embodiment, the receivers 1 to 1 receive the current position of the IC tag 10 by the plurality of receivers 1 to N arranged at predetermined positions in the hospital, and receive the current position. The locus of movement of the IC tag 10 is acquired from the position information of N. At this time, when the current position of the IC tag 10 is received again by the same receiver, the control unit 12 displays the movement trajectory on the display unit 15 excluding the trajectory up to the point of reception again. . Thereby, when the deaf person passes through the same place, the trajectory of the movement so far is not displayed, so that a simple display can be performed. Therefore, the medical staff can easily see the display screen.

  In the above-described embodiment, when the current position of the IC tag 10 is received again by the same receiver, the display is performed excluding the trajectory up to the point where the IC tag 10 has been received again. However, the present invention is not limited to this. For example, only a trajectory from a predetermined time (for example, 10 minutes) before the current time may be displayed.

  Specifically, as shown in FIG. 4, the management device 11 is provided with a timer unit 16 that measures the current time. The control unit 12 selects only the current positions of the IC tags 10 received by the plurality of receivers 1 to N from the current time to a predetermined time before displaying them on the display unit 15. For example, when Mr. A moves from room 2 → room 1 → room 2 → room 3, and the trajectory of movement from the current time to 10 minutes before the predetermined time is room 2 → room 3. As shown in FIG. 5, the control unit 12 displays only the locus from the second room to the third room on the display unit 15.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
