As shown in the figure, in this example, the antenna group 242 has an interval of one wavelength or less of the positioning signal 700 (for example, one wavelength (12.5 cm when the positioning signal 700 is a radio wave in the 2.4 GHz band). ) And four circularly polarized directional antennas 2421 arranged adjacently at equal intervals in a substantially square shape in the following interval).

In the figure, if the angle formed by the horizontal direction at the height position of the antenna group 242 and the direction of the searchee terminal 40 with respect to the antenna group 242 is α,
α = arcTan (D (m) / L (m)) = arcSin (ΔL (cm) / 6 (cm))
It becomes the relationship. ΔL (cm) is a propagation path length difference between two specific antennas 2421 and the searchee terminal 40 among the antennas 2421 constituting the antenna group 242.

Here, when the phase difference between the positioning signals 700 received by two specific antennas 2421 constituting the antenna group 242 is Δθ,
ΔL (cm) = Δθ / (2π / λ (cm))
There is a relationship. Further, for example, when a 2.4 GHz band radio wave is used as the position location signal 700, λ≈12 (cm).
α = arcSin (Δθ / π)
There is a relationship. In addition, within the measurable range (−π / 2 <Δθ <π / 2), α can be calculated from Δθ (radian), so the direction in which the searchee terminal 40 exists can be specified from the above equation.

As shown in FIG. 15, the ground height of the antenna group 242 of the base station 20 is H, the ground height of the searchee terminal 40 is h, and the ground surface directly below the base station 20 is the origin and the orthogonal coordinates (X , Y), and the angle formed by the direction of the search target terminal 40 viewed from the base station 20 and the X axis, which is obtained from the direction α, is ΔΦ (x), which is obtained from the direction α, as viewed from the base station If the angle formed between the direction of the searchee terminal 40 and the Y axis is ΔΦ (y), the positions Δd (x) and Δd (y) of the searchee terminal 40 with respect to the origin can be obtained from the following equations. .
Δd (x) = (H−h) × Tan (ΔΦ (x))
Δd (y) = (H−h) × Tan (ΔΦ (y))
If the position of the origin is (X1, Y1), the current position (Xx, Yy) of the searchee terminal 40 can be obtained from the following equation.
Xx = X1 + Δd (x)
Yy = Y1 + Δd (y)

FIG. 21 shows a schematic configuration of the information processing system 1 described as the second embodiment. As shown in the figure, in the second embodiment, in the configuration of the information processing system 1 of the first embodiment, the server device 10 is connected to an electronic medical record system 80 operated in a hospital.

  The server apparatus 10 can communicate with the electronic medical record system 80 by a wired or wireless communication method (for example, LAN, wireless LAN, Internet, dedicated line, power line communication (PLC (Power Line Communication), etc.)). Connected.

  The electronic medical record system 80 is an information processing system configured using an information processing device and managing information related to a patient's medical record. The name of the medical staff of the hospital 2, the medical history of the patient, and the treatment contents (for example, medication) , Infusion, etc.) are managed in a database.

  FIG. 22 shows a flowchart for explaining the guidance process (hereinafter referred to as guidance process S2200) in the second embodiment.

  As shown in the figure, first, the server device 10 accepts the input of the name of the medical staff, the name of the patient, and the details of the treatment performed on the patient (S2201).

  Subsequently, the server device 10 communicates with the electronic medical record system 80 to display the name of the medical staff, the name of the patient, the treatment content for the patient, and the content input in S2201 managed in the database of the electronic medical record system 80. Collation is performed (S2202).

  As a result of the collation, when the content input in S2201 matches the information managed in the database (S2203: YES), the server device 10 sets the identifier of the patient terminal 40 of the patient input in S2201 in S2201. It transmits to the searcher terminal 50 of the input medical staff (S2204).

  The searcher terminal 50 receives the identifier of the searchee terminal 40 transmitted from the server device 10 (S2205). Thereafter, the process proceeds to S1821. The processing after S1821 is the same as the guidance processing S1800 (S1821 to S1828, S1811 to S1812).

  On the other hand, when the content input in S2201 does not match the information recorded in the electronic medical record system 80 (S2203: NO), the process returns to S2201.

  In this way, prior to starting the guidance, the electronic medical record system 80 collates the input contents, so that the medical staff can be reliably guided to the corresponding patient without mistaken the target patient. be able to.

  The embodiments described above (first example, second example) are for facilitating the understanding of the present invention, and do not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof.
