[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-177342 Summary of the Invention [Problem to be solved by the invention]

[0004] When a portable medical device, such as a wireless telemeter, transmits vital signs to a central monitor, the vital signs are transmitted to the central monitor via a communication network installed within the medical facility, such as an antenna network or an intra-hospital network within the hospital. Therefore, to properly transmit vital signs to the central monitor, it is necessary to regularly monitor the signal strength of the communication network within the medical facility (e.g., the signal strength of antennas and access points installed within the hospital) and maintain a good radio wave environment for the communication network. However, checking the signal strength of the communication network within the medical facility requires at least one person who patrols the hospital carrying the portable medical device and a transmitter, and another person who checks the signal strength from the portable medical device using, for example, a spectrum analyzer connected to the central monitor. In other words, checking the signal strength of the communication network within the medical facility cannot be performed by one person alone, and there is room for improvement in this regard.

[0005] The present disclosure aims to provide a signal strength monitoring system, a signal strength monitoring method, a computer program, and a storage medium that can efficiently monitor the signal strength of a communication network within a medical facility with a small number of personnel. [Means for solving the problem]

[0006] In order to achieve the above object, a signal strength monitoring system according to one aspect includes: a portable medical device that can be carried by a user; a transmitting device portable by the user, capable of transmitting measurement location information for identifying a plurality of areas covered by a plurality of radio wave transmitters installed in a medical facility and communicating with the portable medical device, and time axis information relating to the time when the user was present at a measurement location corresponding to the measurement location information or the measurement order of the measurement locations; an acquisition device that acquires signal strength information regarding the signal strength of the radio wave transmitter that communicates with the portable medical device, the signal strength information corresponding to the time axis information; and an integration device that acquires the measurement position information and the time axis information from the transmitting device, acquires the signal strength information corresponding to the time axis information from the acquiring device, and generates integrated information that associates the measurement position information and the signal strength information based on the time axis information.

[0007] Further, a signal strength monitoring method according to one aspect for achieving the above object includes: a step of acquiring, from a transmitting device portable by a user, measurement location information for identifying a plurality of areas covered by a plurality of radio wave transmitters installed in a medical facility and communicating with a portable medical device, and time axis information relating to the time when the user was present at a measurement location corresponding to the measurement location information or the measurement order of the measurement locations; acquiring signal strength information relating to the signal strength of the radio wave transmitter communicating with the portable medical device, the signal strength corresponding to the time axis information; and generating integrated information that associates the measurement position information with the signal strength information based on the time axis information.

[0008] Furthermore, a computer program according to one aspect for achieving the above object comprises: a function of acquiring, from a transmitting device portable by a user, measurement location information for identifying a plurality of areas covered by a plurality of radio wave transmitters installed in a medical facility and communicating with a portable medical device, and time axis information relating to the time when the user was present at a measurement location corresponding to the measurement location information or the measurement order of the measurement locations; a function of acquiring signal strength information relating to the signal strength of the radio wave transmitter communicating with the portable medical device, the signal strength corresponding to the time axis information; The computer is caused to realize a function of generating integrated information that associates the measurement position information with the signal strength information based on the time axis information.

[0009] In addition, a non-transitory computer-readable medium according to one aspect for achieving the above object includes: The computer program is stored.

[0010] According to the signal strength monitoring system having the above configuration, the integrating device acquires measurement location information and time axis information from the transmitting device and acquires signal strength information corresponding to the time axis information acquired from the transmitting device from the acquiring device. The integrating device then generates integrated information associating the measurement location information with the signal strength information based on the time axis information. In other words, a user carrying a portable medical device and a transmitting device simply measures the signal strength of radio waves transmitted from multiple radio wave transmitters installed within a medical facility, and the integrating device generates integrated information associating the measurement location information with the signal strength information. Therefore, a single user can obtain the information necessary to monitor the signal strength of a communication network within a medical facility. Therefore, the signal strength monitoring system having such a configuration can efficiently monitor the signal strength of a communication network within a medical facility with a small number of personnel. The signal strength monitoring method, computer program, and storage medium having the above configuration can also achieve similar effects. [Effects of the Invention]

[0013] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the drawings.

[0014] (First embodiment) A signal strength monitoring system 1 according to a first embodiment will be described with reference to Figures 1 and 2. Figure 1 is a schematic diagram illustrating the signal strength monitoring system 1 according to an embodiment of the present invention. The signal strength monitoring system 1 is used, for example, in a medical facility 100 such as a hospital (see Figure 4). A plurality of antennas 10 (an example of a radio wave transmitter) are installed in the medical facility 100. For convenience of explanation, only one antenna 10 is illustrated in Figure 1. As illustrated in Figure 1, the signal strength monitoring system 1 includes a portable medical device 2, a first communication device (an example of a transmitting device) 3, a spectrum analyzer (an example of an acquiring device) 4, a second communication device (an example of an integrating device) 5, and a receiving device 6.

[0015] The portable medical device 2 can be carried by a user U who travels around the medical facility 100. The portable medical device 2 can communicate with an antenna 10. The portable medical device 2 is communicatively connected to a receiving device 6 via an antenna network 7 (an example of a communication network within the medical facility) and a communication cable 8. The portable medical device 2 is also communicatively connected to a spectrum analyzer 4 via the antenna network 7 and the communication cable 8. The portable medical device 2 is, for example, a portable medical telemeter for measuring and displaying biological information of a patient. The portable medical device 2 is configured to measure biological information of a patient, etc. Examples of the biological information include blood pressure information and electrocardiogram information. The portable medical device 2 transmits the biological information to the receiving device 6 via, for example, the antenna network 7 and the communication cable 8.

[0016] A user U is a person who monitors the signal strength of the antenna network 7. For example, the user U simulates a patient and uses a portable medical device 2 to transmit biological information acquired from the patient in the medical facility 100 to the receiving device 6 via the antenna 10 and the antenna network 7, thereby monitoring the signal strength of the antenna network 7 (the signal strength of the radio waves transmitted from the antenna 10). Note that, for convenience of explanation, only one portable medical device 2 is illustrated in the example shown in FIG. 1 , but the signal strength monitoring system 1 may include multiple portable medical devices 2. In this case, for example, each of the multiple users U carries a portable medical device 2 and moves around the medical facility 100.

[0017] When transmitting acquired biological information, the portable medical device 2 transmits radio waves according to a predetermined channel toward the antenna 10. The transmitted radio waves are sent continuously in time to the spectrum analyzer 4 via the antenna 10 and the antenna network 7. The portable medical device 2 also transmits channel information (see FIG. 2) to the spectrum analyzer 4 as identification information for distinguishing the portable medical device 2 from other portable medical devices. The channel information is information related to a frequency band and corresponds to the frequency to be used. In the example shown in FIG. 2, the frequency to be used is 425.1 MHz, and the channel is 2050.

[0018] Returning to FIG. 1 , the first communication device 3 will be described. The first communication device 3 is, for example, a terminal device portable by the user U, such as a tablet terminal, a smartphone, or a laptop computer. The first communication device 3 includes a memory and a processor. The memory is configured to store computer-readable instructions (computer programs). For example, the memory may include a read-only memory (ROM) storing various computer programs and a random access memory (RAM) having multiple work areas storing various computer programs executed by the processor. The memory of the first communication device 3 may also store map information related to a map of the medical facility 100 and grid-like map information (described later). The processor may include, for example, at least one of a central processing unit (CPU), a microprocessing unit (MPU), and a graphics processing unit (GPU). The CPU may include multiple CPU cores. The GPU may include multiple GPU cores. The processor is configured, for example, to load a computer program specified by various computer programs stored in the ROM onto the RAM and execute various processes in cooperation with the RAM.

[0019] The first communication device 3 can transmit measurement position information and time information (an example of time axis information) to the second communication device 5, for example, by wireless communication. The measurement position information is information related to the position where the user U measured the signal strength (hereinafter also referred to as the measurement position). The measurement position corresponds, for example, to the position where the user U measured the patient's biological information using the portable medical device 2. The measurement position information includes position identification information associated with a position in the medical facility 100. The position identification information is, for example, room number information related to the room numbers assigned to each room in the medical facility 100, coordinate information for identifying the positions of rooms in the medical facility 100 and each point in the medical facility 100 on a grid map (described later), and area information such as area numbers assigned to each area in the medical facility 100. The user U can identify the measurement position on a map related to the medical facility 100 using the position identification information. In addition, the measurement position information can be used to identify multiple areas covered by multiple antennas 10 installed in the medical facility 100. The time information is information relating to the time when the user U was present at a position where the user U measured the signal strength (measurement position). The time when the user U was present at the measurement position corresponds, for example, to the time when the user U measured the patient's biological information using the portable medical device 2 or the time when the user U transmitted a pseudo signal, which is a signal for test transmission. The first communication device 3 acquires the measurement position information and the time information, for example, by the user U touching a specific position on a map displayed on a display unit (not shown) of the first communication device 3 or on a grid map (described later). However, the first communication device 3 may also acquire the measurement position information and the time information by the user U inputting the measurement position and the measurement time into an input unit (not shown) of the first communication device 3.

[0020] The spectrum analyzer 4 is communicatively connected to the portable medical device 2 via the antenna network 7 and a communication cable 8. The spectrum analyzer 4 is communicatively connected to the second communication device 5 via a communication cable 11. The spectrum analyzer 4 acquires signal strength information for each frequency by analyzing the distribution of frequency components contained in the radio wave signal related to the radio waves received by the antenna 10 per unit time. The spectrum analyzer 4 transmits the signal strength information to the second communication device 5 via the communication cable 11 in response to an input operation to an input unit (not shown) provided in the spectrum analyzer 4.

[0021] The second communication device 5 is, for example, a terminal device such as a tablet terminal, a smartphone, or a laptop computer. The second communication device 5 includes a memory, a processor, a wireless communication unit, and a wired communication unit. The memory of the second communication device 5 may have the same configuration as the memory of the first communication device 3. The memory of the second communication device 5 stores coverage area information regarding each area covered by each of the multiple antennas 10. The coverage area information is, for example, table information for associating each antenna 10 with the area covered by each antenna 10. The processor of the second communication device 5 may have the same configuration as the processor of the first communication device 3. The wireless communication unit of the second communication device 5 is configured to be able to communicate with the first communication device 3 via a wireless communication means such as Bluetooth (registered trademark) that allows mutual authentication. The wired communication unit of the second communication device 5 is configured to be able to communicate with the spectrum analyzer 4 via a communication cable 11, for example, via a serial connection.

[0022] The second communication device 5 receives the biological information from the receiving device 6, for example, via a communication network installed in the medical facility 100. The second communication device 5 receives signal strength information from the spectrum analyzer 4 via a communication cable 11. The processor of the second communication device 5, for example, loads a computer program specified from various computer programs stored in the ROM onto the RAM, and executes various processes in cooperation with the RAM, thereby executing the processes described in detail below.

[0023] In this embodiment, a computer-readable medium may be used. A computer-readable medium refers to any type of physical memory (RAM, ROM, etc.) that can store information or data that can be read by a processor. A computer-readable medium may store instructions for execution by one or more processors. Note that the term "computer-readable medium" encompasses tangible items and excludes carrier waves and transitory signals (i.e., non-transitory). Non-transitory computer-readable media include, for example, magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs)), and the like. ROM), EPROM (Erasable PROM), and Flash ROM).

[0024] The receiving device 6 is, for example, a central monitor. The receiving device 6 is installed, for example, in a nurse's station 107 (see FIG. 4 ). The receiving device 6 receives the biological information from the portable medical device 2 via an antenna network 7 and a communication cable 8. The receiving device 6 is configured to display the patient's biological information received from the portable medical device 2. The receiving device 6 can transmit the biological information to the second communication device 5 via a communication network installed in the medical facility 100.

[0025] The antenna network 7 is configured to transmit various types of information to the spectrum analyzer 4 and the receiving device 6 using a plurality of antennas 10, for example.

[0026] Next, a signal strength monitoring method executed by the signal strength monitoring system 1 will be described with reference to FIGS. 3 to 7. In this embodiment, a user U, carrying a portable medical device 2 and a first communication device 3, travels around hospital rooms 101 to 105, a staff station 106, and a nurse station 107 in a medical facility 100 illustrated in FIGS. 4 and 5, and monitors the signal strength of multiple antennas 10 installed in the medical facility 100. Numbers assigned to each room indicate the room numbers of the rooms. In this embodiment, the user U measures signal strength at measurement positions P1 to P7 in each room. In this embodiment, antennas 10A to 10G are installed in the medical facility 100. Antenna 10A covers measurement position P1 in hospital room 101 (i.e., antenna 10A can communicate at measurement position P1). Antenna 10B covers measurement position P2 in hospital room 102. Antenna 10C covers measurement position P3 in hospital room 103. Antenna 10D covers measurement position P4 in hospital room 104. Antenna 10E covers measurement position P5 in hospital room 105. Antenna 10F covers measurement position P6 in staff station 106. Antenna 10G covers measurement position P7 in nurse station 107. Note that in medical facility 100, antennas other than antennas 10A to 10G may be installed in rooms other than hospital rooms 101 to 105, staff station 106, and nurse station 107. In this case, user U patrols rooms other than hospital rooms 101 to 105, staff station 106, and nurse station 107 and monitors the signal strength of other antennas covering measurement positions in those rooms.

[0027] As illustrated in FIG. 3, the user U stores map information of the medical facility 100 in the first communication device 3 (STEP 01). For example, the user U stores the map information of the medical facility 100 in the first communication device 3 by downloading the map information of the medical facility 100 stored in a server in the medical facility 100 to the first communication device 3. However, the user U may also store the map information of the medical facility 100 in the first communication device 3 by, for example, capturing an image of the map of the medical facility 100 with a camera (not shown) provided in the first communication device 3. In this embodiment, the map based on the map information of the medical facility 100 stored in the first communication device 3 is the map illustrated in FIG. 4. The map information is electronic information that can be stored in the memory of the first communication device 3 in a format such as PDF or JPEG. In this embodiment, the medical facility 100 is divided into four areas. Each of the four areas is assigned an area number, Area A1 to Area A4. Area A1 includes patient rooms 101 to 103 and a staff station 106. Area A2 includes a first day room 108 and a machine room 109. Area A3 includes patient rooms 104 to 105, a nurse station 107, a lounge 110, an equipment room 111, a shower room 113 and a men's changing room 114. Area A4 includes a work corner 112, a rest room 115, a women's changing room 116 and a second day room 117.

[0028] As illustrated in Fig. 3, the user U performs an input operation on the input unit of the first communication device 3 to perform a process of overlaying map information of the medical facility 100 stored in the first communication device 3 with grid information such as coordinate information relating to coordinates having an arbitrary number of rows and columns. Based on the input operation, the first communication device 3 generates grid map information (STEP 02). In this embodiment, the grid map based on the grid map information is the map illustrated in Fig. 5.

[0029] As shown in FIG. 5, the grid map includes coordinates consisting of seven rows (rows 1 to 7) and eleven columns (columns A to K). While the coordinates shown in FIG. 5 are grid-like coordinates, they may be point-like coordinates, for example. Furthermore, the shape of the grid is not limited to a square, and may be other shapes such as a rectangle or a circle. In this embodiment, each room is considered to be located at the coordinates where the majority or a major part of the room is located. For example, the majority of the hospital room 101 is located in grid C1, and therefore the hospital room 101 is considered to be located in grid C1. The staff station 106 is considered to be located in grid A2, which includes the installation position of the antenna 10F and the measurement position P6.

[0030] 3, the user U synchronizes the time between the first communication device 3 and the spectrum analyzer 4 (STEP 03). Specifically, the user U accesses, for example, an NTP (Network Time Protocol) server to synchronize the time between the first communication device 3 and the spectrum analyzer 4, and then confirms that the time between the first communication device 3 and the spectrum analyzer 4 matches. If the time between the first communication device 3 and the spectrum analyzer 4 does not match, the user U synchronizes the time between the spectrum analyzer 4 and the time between the first communication device 3 and the spectrum analyzer 4.

[0031] A user U moves sequentially through hospital rooms 101 to 105, staff station 106, and nurse station 107, which are included in the area covered by antennas 10A to 10F installed in medical facility 100. First, user U moves to hospital room 101 (see FIG. 4), for example. As illustrated in FIG. 3, after moving to hospital room 101, user U measures the patient's biological information using portable medical device 2 (STEP 04). Note that the measurement of the patient's biological information is preferably performed for a predetermined period of time or more in order to properly measure signal strength. Furthermore, the measurement of the biological information may be performed using waveform generation in a demonstration mode instead of actual measurement.

[0032] The portable medical device 2 transmits the biological information to the receiving device 6 via the antenna 10A, the antenna network 7, and the communication cable 8. The receiving device 6 also transmits the received biological information to the second communication device 5, for example, via a communication network installed in the medical facility 100. However, the timing at which the receiving device 6 transmits the biological information to the second communication device 5 is arbitrary. That is, the receiving device 6 may, for example, transmit the received biological information to the second communication device 5 sequentially, or may transmit the received biological information to the second communication device 5 all at once after measuring the signal strength. Note that in STEP 04, instead of transmitting the patient's biological information to the receiving device 6, a pseudo signal may be transmitted to the receiving device 6 via the antenna 10A, the antenna network 7, and the communication cable 8. When transmitting the biological information or the pseudo signal to the receiving device 6, the portable medical device 2 transmits a radio wave signal related to the radio waves emitted from the portable medical device 2 to the spectrum analyzer 4 via the antenna 10A, the antenna network 7, and the communication cable 8.

[0033] The spectrum analyzer 4 analyzes the radio signal received by the antenna 10A to obtain signal strength information of the antenna 10A corresponding to the time when the user U was present at the measurement position P1 (STEP 05). Specifically, the spectrum analyzer 4 analyzes the distribution of frequency components contained in the radio signal received by the antenna 10A, and obtains signal strength information on the signal strength of the antenna 10A corresponding to the measurement time at the measurement position P1 based on the analysis results.

[0034] When the user U finishes measuring the signal strength of the antenna 10A in the hospital room 101, the user U displays a grid map on the display unit of the first communication device 3 and touches a position on the grid map corresponding to the measurement position to input the measurement position and the measurement time (STEP 06). However, the user U may also display a map such as the example shown in FIG. 4 on the display unit of the first communication device 3 and touch a position on the map corresponding to the measurement position to input the measurement position and the measurement time. Alternatively, the user U may input the measurement position and the measurement time into an input unit provided in the first communication device 3.

[0035] Next, the first communication device 3 determines whether to end the signal strength measurement based on an input operation by the user U (STEP 07). To end the signal strength measurement, for example, the user U performs an input operation to end the signal strength measurement on an input unit provided in the first communication device 3, and the first communication device 3 determines to end the signal strength measurement based on the input operation. However, the first communication device 3 may automatically determine to end the signal strength measurement, for example, when there is no input operation by the user U for a predetermined time or more. If the signal strength measurement is to be ended (YES in STEP 07), the process proceeds to STEP 08. If the signal strength measurement is not to be ended (NO in STEP 07), the process returns to STEP 04. In this embodiment, the signal strength is also measured in the hospital rooms 102 to 105, the staff station 106, and the nurse station 107 (NO in STEP 07), so the process returns to STEP 04. Therefore, the user U moves to the hospital rooms 102 to 105, the staff station 106, and the nurse station 107, and repeats STEPs 04 to 06.

[0036] Here, measurement of signal strength in hospital room 102 will be described. Hospital room 102 is covered by antennas 10A and 10B. As illustrated in FIG. 4, antenna 10B is closer to measurement position P2 in hospital room 102 than antenna 10A, and therefore the radio wave strength of antenna 10B at measurement position P2 is stronger than the radio wave strength of antenna 10A at measurement position P2. For this reason, it is preferable that the biological information acquired by portable medical device 2 is transmitted from portable medical device 2 to receiving device 6 via antenna 10B. Accordingly, in this embodiment, the biological information acquired by portable medical device 2 at measurement position P2 in hospital room 102 is transmitted from portable medical device 2 to receiving device 6 via antenna 10B. Note that measurement of signal strength in hospital rooms 103 to 105, staff station 106, and nurse station 107 is similar to measurement of signal strength in hospital room 101, and therefore description thereof will be omitted. However, when measuring the signal strength at the staff station 106 and the nurse station 107, a pseudo signal may be transmitted from the portable medical device 2 to the receiving device 6 via the antennas 10F and 10G.

[0037] When user U finishes measuring the signal strength in hospital rooms 101 to 105, staff station 106, and nurse station 107, user U performs an input operation to end the signal strength measurement on the input unit of first communication device 3. When user U performs an input operation to end the signal strength measurement on the input unit of first communication device 3 (YES in STEP 07 of FIG. 3), first communication device 3 generates measurement position information and time information based on each measurement position and each measurement time input in STEP 06. First communication device 3 transmits the measurement position information and time information to second communication device 5 (STEP 08).

[0038] Next, the user U performs an input operation on an input unit of the spectrum analyzer 4 to transmit the acquired signal strength information from the spectrum analyzer 4 to the second communication device 5. As illustrated in FIG. 3 , the spectrum analyzer 4 transmits the acquired signal strength information to the second communication device 5 via the communication cable 11 in response to the input operation by the user U (STEP 09). Note that the spectrum analyzer 4 may transmit the acquired signal strength information to the second communication device 5 via the communication cable 11 each time it acquires the signal strength information. In this way, the second communication device 5 acquires the signal strength information.

[0039] The second communication device 5 identifies antennas 10A to 10G that cover measurement positions P1 to P7 based on the measurement position information and the coverage area information (STEP 10). The second communication device 5 identifies the antenna that covers measurement position P1 as antenna 10A. The second communication device 5 identifies the antennas that cover measurement position P2 as antennas 10A and 10B. The second communication device 5 identifies the antenna that covers measurement position P3 as antenna 10C. The second communication device 5 identifies the antenna that covers measurement position P4 as antenna 10D. The second communication device 5 identifies the antenna that covers measurement position P5 as antenna 10E. The second communication device 5 identifies the antenna that covers measurement position P6 as antenna 10F. The second communication device 5 identifies the antenna that covers measurement position P7 as antenna 10G.

[0040] The second communication device 5 generates integrated information that associates the measurement position information with the signal strength information based on the time information (STEP 11). The integrated information includes, for example, time information, measurement position information, and signal strength information, and is information for displaying in a list the time, position, and signal strength at which the signal strength of each of the antennas 10A to 10G was measured. The measurement position information and signal strength information included in the integrated information are linked based on the time information.

[0041] The second communication device 5 associates the signal strength information with the biological information based on the time information (STEP 12).

[0042] The second communication device 5 generates display data D1 (see FIG. 6) that displays signal strength information for each point in the medical facility 100 based on the measurement position information, time information, and signal strength information (STEP 13). A display image based on the display data D1 is, for example, the display image illustrated in FIG. 6. The display data D1 includes information about the rooms in which the signal strength measurements were performed, information about the area to which each room belongs, information about the square on the map to which each room belongs, measurement position information, measurement time information, and information about the measurement results. For example, signal strength measurement in a hospital room 101 belonging to area A1 was performed at measurement position P1 at 15:30, and the signal strength was 48 dB.

[0043] In STEP 13, the second communication device 5 determines whether the signal strength is equal to or less than a predetermined value for each of measurement positions P1 to P7 in the medical facility 100 based on the measurement position information and the signal strength information. In this embodiment, two predetermined values ​​(a first predetermined value indicating a warning and a second predetermined value indicating a caution) are set. The first predetermined value is 30 dB, and the second predetermined value is 40 dB. In other words, the seriousness of a caution is less serious than the seriousness of a warning.

[0044] The measurement results in this embodiment are as shown in FIG. 6. Therefore, the second communication device 5 determines that the signal strengths at measurement positions P1 to P2 and measurement positions P6 to P7 are greater than the second predetermined value. The second communication device 5 determines that the signal strength at measurement position P4 is greater than the first predetermined value but is equal to or less than the second predetermined value. The second communication device 5 determines that the signal strengths at measurement positions P3 and P5 are equal to or less than the first predetermined value. The display data D1 includes distinction information for distinguishing, among the multiple pieces of signal strength information displayed, signal strength information whose signal strength exceeds the first predetermined value but is equal to or less than the second predetermined value, signal strength information whose signal strength is equal to or less than the first predetermined value, and signal strength information whose signal strength exceeds the second predetermined value. In this embodiment, each piece of signal strength information is distinguished using hatching. As shown in FIG. 6, signal strengths whose signal strength is equal to or less than the first predetermined value are hatched with vertical lines. Signal strengths whose signal strength is equal to or greater than the first predetermined value but is equal to or less than the second predetermined value are hatched with horizontal lines. The method for distinguishing between the signal strength information is not limited to hatching. For example, different colors may be used for signal strength portions that are equal to or less than a first predetermined value and signal strength portions that are greater than the first predetermined value but are equal to or less than a second predetermined value.

[0045] The second communication device 5 can also generate display data D2 (see FIG. 7) that displays signal strength information for each measurement position P1 to P7 in the medical facility 100 based on measurement position information, time information, and signal strength information generated multiple times on different dates. A display image based on the display data D2 is the display image illustrated in FIG. 7. The display image illustrated in FIG. 7 displays measurement results on January 12, 2021, February 21, 2021, and March 22, 2021 in chronological order. In other words, the display image illustrated in FIG. 7 displays measurement results on three different dates in chronological order. Note that the display "N / A" in the display image illustrated in FIG. 7 indicates that signal strength measurement was not performed. Furthermore, the display data D2 includes distinction information for distinguishing, among the multiple pieces of signal strength information displayed, signal strength information whose signal strength exceeds a first predetermined value but is equal to or less than a second predetermined value, signal strength information whose signal strength is equal to or less than the first predetermined value, and signal strength information whose signal strength exceeds the second predetermined value. Therefore, as illustrated in Fig. 7, signal strengths whose signal strength is equal to or less than the first predetermined value are hatched with vertical lines. Signal strengths whose signal strength is equal to or less than the first predetermined value are hatched with horizontal lines.

[0046] For example, at measurement position P1 in hospital room 101, signal strength measurements were taken on January 12, 2021, and March 22, 2021, with the measurement results being 10 dB and 48 dB, respectively. Therefore, the signal strength of antenna 10A at measurement position P1 on January 12, 2021, was 10 dB, which is below the first predetermined value, but the signal strength of antenna 10A at measurement position P1 on March 22, 2021, was 48 dB, which is above the second predetermined value, indicating that the signal strength has improved. At measurement position P2 in hospital room 102, signal strength measurements were taken on January 12, 2021, February 21, 2021, and March 22, 2021, with the measurement results being 53 dB, 48 dB, and 44 dB, respectively. Therefore, since the signal strength of antenna 10B at measurement position P2 exceeds the second predetermined value on all measurement days, there is no need for immediate maintenance of antenna 10B, but it is clear that the signal strength is gradually weakening. Maintenance of antennas 10A to 10G includes, for example, repairing faulty parts of antennas 10A to 10G, adjusting the positions of antennas 10A to 10G, or replacing them with other antennas. At measurement position P5 in hospital room 105, signal strength measurements were performed on January 12, 2021, February 21, 2021, and March 22, 2021, with the measurement results being 20 dB, 15 dB, and 10 dB, respectively. Therefore, since the signal strength of antenna 10E at measurement position P5 was below the first predetermined value on all measurement days and the signal strength is gradually weakening, it is clear that immediate maintenance of antenna 10E is required.

[0047] The second communication device 5 can further generate display data for displaying the signal strength information and the biological information associated based on the time information, for example, on a display unit (not shown) included in the first communication device 3 or the second communication device 5. A display screen based on the display data is, for example, a display screen shown in FIG. 6 or 7, on which the biological information associated based on the time information is additionally displayed. The added biological information can be appropriately selected by the user U. By visually checking a display image based on the display data displayed on a display unit included in the first communication device 3 or the second communication device 5, the user U can determine the biological information and the signal strength at the time the biological information was measured. The display screen may display a link for displaying biological information (e.g., an electrocardiogram waveform), or may display a noise level calculated from the biological information.

[0048] According to the signal strength monitoring system 1, signal strength monitoring method, computer program, and non-transitory computer-readable medium having the computer program stored thereon, the second communication device 5 acquires measurement location information and time information from the first communication device 3 and acquires signal strength information corresponding to the time information acquired from the first communication device 3 from the spectrum analyzer 4. The second communication device 5 also generates integrated information associating the measurement location information and the signal strength information based on the time information. In other words, simply by having a user U carrying a portable medical device 2 and the first communication device 3 measure the signal strength of radio waves transmitted from multiple antennas 10 installed within the medical facility 100, the second communication device 5 generates integrated information associating the measurement location information and the signal strength information. Therefore, a single user U can obtain the information necessary to monitor the signal strength of the antenna network 7 within the medical facility 100. Therefore, the signal strength monitoring system 1 allows efficient monitoring of the signal strength of the antenna network 7 within the medical facility 100 with a small number of personnel.

[0049] Furthermore, in the signal strength monitoring system 1 having the above configuration, the portable medical device 2 and the spectrum analyzer 4 are separate devices. Therefore, the user U can monitor the signal strength of the antenna network 7 within the medical facility 100 using the portable medical device 2 with a simple configuration.

[0050] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the second communication device 5 is a device different from the portable medical device 2, the first communication device 3, and the spectrum analyzer 4, so the configuration of the second communication device 5 can be simplified.

[0051] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the user U can use the channel information as identification information for distinguishing between the portable medical device 2 and other portable medical devices to identify which portable medical device 2 transmitted the biological information. Therefore, even when multiple people measure signal strength using multiple portable medical devices 2, the user U can easily recognize which portable medical device 2 was used to measure the signal strength based on the channel information.

[0052] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the second communication device 5 can identify the antennas 10A to 10G that cover measurement positions P1 to P7 based on the measurement position information and the coverage area information. Therefore, the user U can identify the antennas 10A to 10G that should be measured at a certain measurement position. Furthermore, for example, if the signal strength of the antenna 10E that should be measured is below a first predetermined value and the signal strength is weak, the user U can determine that the antenna 10E should be maintained.

[0053] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the measurement location information includes location identification information (room number information, coordinate information, and area information), so that the user U can easily understand at which location in the medical facility 100 the signal strength information is.

[0054] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the user U can accurately grasp the measurement positions P1 to P7 on a map. In particular, in this embodiment, the position identification information includes coordinate information, so that the measurement positions P1 to P7 can be uniquely identified. As a result, the user U can monitor the signal strength of the antenna network 7 more accurately and easily.

[0055] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the second communication device 5 determines whether the signal strength is equal to or less than a predetermined value (in this embodiment, a first predetermined value and a second predetermined value) for each of measurement positions P1 to P7. Therefore, by using the determination result by the second communication device 5, the user U can easily recognize the location where the signal strength is equal to or less than the predetermined value.

[0056] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the second communication device 5 generates display data D2. The display image based on the display data D2 displays measurement results on three different dates in chronological order. Therefore, by using the display data D2, the user U can easily grasp the transition of signal strength at each point (measurement position P1 to measurement position P7).

[0057] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the display data D1 and the display data D2 include distinguishing information. Therefore, by using the distinguishing information, the user U can easily distinguish, among the multiple pieces of signal strength information displayed, between signal strength information whose signal strength is equal to or less than a predetermined value and signal strength information whose signal strength is greater than the predetermined value.

[0058] Furthermore, according to the signal strength monitoring system 1 having the above configuration, the second communication device 5 associates the signal strength information with the biometric information based on time information. The second communication device 5 generates display data for displaying the associated signal strength information and biometric information based on the time information, for example, on a display unit provided in the first communication device 3 or the second communication device 5. A display image based on the display data is displayed on the display unit provided in the first communication device 3 or the second communication device 5, allowing the user U to check the associated signal strength information and biometric information based on the time information as a set. As a result, if the biometric information cannot be received normally, the user U can infer whether the radio wave environment is the cause of the inability to receive the biometric information normally.

[0059] Second Embodiment Next, a signal strength monitoring system 1A according to a second embodiment will be described with reference to FIGS. 3 and 8. In this embodiment, components similar to those in the first embodiment are denoted by the same reference numerals, and overlapping descriptions will be omitted where appropriate. The signal strength monitoring system 1A differs from the signal strength monitoring system 1 according to the first embodiment in that it includes a portable medical device 2A instead of the portable medical device 2 and does not include a spectrum analyzer 4. This embodiment also differs from the first embodiment in that the biometric information acquired by the portable medical device 2A is transmitted to the receiving device 6 via an access point AP (an example of a radio wave transmitter) and an in-hospital network 70 (an example of a communication network within a medical facility). In this embodiment, the signal strength monitoring system 1A executes the signal strength monitoring method illustrated in FIG. 3.

[0060] As illustrated in FIG. 8, the signal strength monitoring system 1A includes a portable medical device 2A, a first communication device (an example of a transmitting device) 3, a second communication device (an example of an integrating device) 5, and a receiving device 6.

[0061] The portable medical device 2A includes a memory, a processor, and a wireless communication unit. The portable medical device 2A transmits acquired biometric information to the receiving device 6 via an access point AP and an in-hospital network 70. While only one access point AP is illustrated in the example shown in FIG. 8 for ease of explanation, in this embodiment, multiple access points AP are installed instead of antennas at the positions of antennas 10A to 10F in the first embodiment. Furthermore, the biometric information acquired by the portable medical device 2A is transmitted to the receiving device 6 via the access point AP determined to have the strongest signal strength through roaming. This is because the stronger the signal strength, the more stable the communication. Roaming refers to maintaining a network connection state by starting a communication connection with an access point other than the currently connected access point when a communication terminal communicating with the access point moves out of the communication connection range of the currently connected access point. However, the portable medical device 2A may also start roaming when the signal strength of the currently connected access point falls below a predetermined value. In this case, the portable medical device 2A is connected to the access point AP with the strongest signal strength at the start of roaming.

[0062] The portable medical device 2A communicates with the access point AP to acquire RSSI (Received Signal Strength Indicator) information (an example of signal strength information) indicating the signal strength of the access point AP with which the portable medical device 2A is communicating. Therefore, in this embodiment, the portable medical device 2A is an example of an acquisition device. For this reason, the signal strength monitoring system 1A does not include a spectrum analyzer 4. The portable medical device 2A can log time information, channel information, and RSSI information. Logging is a process of writing various types of information to a memory. In other words, the portable medical device 2A stores various types of information, such as the RSSI information, in a memory provided in the portable medical device 2A. The user U can transmit the various types of information stored in the memory from the portable medical device 2A to the second communication device 5 by performing an input operation on an input unit (not shown) provided in the portable medical device 2A to transmit the various types of information stored in the memory of the portable medical device 2A to the second communication device 5.

[0063] The hospital network 70 is, for example, an IP network installed in a medical facility. The hospital network 70 is configured to transmit, for example, biological information and the like to the receiving device 6. Although not shown in FIG. 8, the hospital network 70 may also include a switching hub. A switching hub is a device that operates at the data link layer of the OSI reference model and has the function of relaying communications between multiple hosts of a repeater hub and the function of decoding the headers of Ethernet (registered trademark) frames at the data link layer.

[0064] Next, a signal strength monitoring method executed by the signal strength monitoring system 1A will be described. The signal strength monitoring system 1A executes the signal strength monitoring method exemplified in Fig. 3. STEP 01 to STEP 02 are the same as those in the first embodiment.

[0065] In STEP 03, the user U synchronizes the time on the portable medical device 2A with the time on the first communication device 3. Specifically, the user U accesses an NTP server to synchronize the time on the first communication device 3, and then confirms that the time on the portable medical device 2A matches the time on the first communication device 3. If the time on the portable medical device 2A does not match the time on the first communication device 3, the user U synchronizes the time on the portable medical device 2A with the time on the first communication device 3.

[0066] A user U moves sequentially through hospital rooms 101 to 105, a staff station 106, and a nurse station 107, which are included in an area covered by a plurality of access points AP installed in a medical facility 100. First, the user U moves to, for example, hospital room 101 and measures signal strength at measurement position P1. At measurement position P1, the user U measures the patient's biological information using a portable medical device 2A (STEP 04). The portable medical device 2A transmits the biological information to a receiving device 6 via the access point AP, the hospital network 70, and the communication cable 8. The receiving device 6 also transmits the received biological information to a second communication device 5 via, for example, a communication network installed in the medical facility 100. However, the timing at which the receiving device 6 transmits the biological information to the second communication device 5 is arbitrary. In STEP 04, the portable medical device 2A may transmit a pseudo signal, instead of the patient's biological information, to the receiving device 6 via the access point AP, the hospital network 70, and the communication cable 8.

[0067] When transmitting biological information to the receiving device 6, the portable medical device 2A communicates with the access point AP to acquire RSSI information indicating the signal strength of the access point AP with which it is communicating. That is, the portable medical device 2A acquires the signal strength information of the access point AP with which it is communicating (STEP 05). Note that the RSSI information is signal strength information corresponding to each time when the user U was present at measurement positions P1 to P7. The portable medical device 2A logs the time information, channel information, and RSSI information.

[0068] STEP 06 to STEP 08 are the same as in the first embodiment. However, in this embodiment, roaming is performed, so if the user U does not end the signal strength measurement (NO in STEP 07), the portable medical device 2A will be connected to the most appropriate access point AP for transmitting biological information simply by moving to another room. Therefore, the user U can measure the signal strength of all the access points AP that are the measurement targets by simply moving around the predetermined measurement positions (measurement positions P1 to P7) within the medical facility 100.

[0069] The user U performs an operation on an input unit of the portable medical device 2A to transmit the acquired RSSI information to the second communication device 5. In response to the input operation by the user U, the portable medical device 2A transmits the acquired RSSI information to the second communication device 5, for example, by wireless communication (STEP 09). In this way, the second communication device 5 acquires the RSSI information.

[0070] STEP 10 to STEP 13 are the same as in the first embodiment.

[0071] The signal strength monitoring system 1A, the signal strength monitoring method, the computer program, and the non-transitory computer-readable medium storing the computer program according to the above configuration can also achieve the same effects as those of the first embodiment.

[0072] Furthermore, according to the signal strength monitoring system 1A having the above configuration, the portable medical device 2A can acquire RSSI information, and therefore the user U can monitor the signal strength of the in-hospital network 70 within the medical facility 100 without using a spectrum analyzer.

[0073] The above-described embodiments are provided to facilitate understanding of the present disclosure, and are not intended to limit the present disclosure, which may be modified or improved without departing from the spirit and scope of the present disclosure.

[0074] In the above embodiment, the first communication device 3 transmits measurement location information and time information to the second communication device 5, but the present disclosure is not limited to this. The first communication device 3 may transmit, for example, measurement location information and order information (an example of time axis information) relating to the order in which the measurement locations are measured to the second communication device 5. The order information is information for identifying the temporal order of measurements of signal strength at each measurement location. The order information is, for example, number information relating to numbers assigned in the order in which the signal strength is measured, character information relating to characters indicating the order of measurement, symbol information relating to symbols indicating the order of measurement, etc.

[0075] In the above embodiments, the second communication device 5 is a terminal device such as a tablet terminal, smartphone, or laptop computer, but may also be a portable medical device or spectrum analyzer capable of executing the processing performed by the second communication device 5 in the above embodiments. Furthermore, in the above embodiments, the signal strength monitoring system 1, 1A includes the first communication device 3 and the second communication device 5, but does not necessarily include the second communication device 5. That is, the first communication device 3 and the second communication device 5 may be the same device. If the first communication device 3 and the second communication device 5 are the same device, the first communication device 3 executes the processing performed by the second communication device 5 in the above embodiments. In these cases, the user U can monitor the signal strength of the antenna network 7 or the in-hospital network 70 within the medical facility 100 without preparing the second communication device 5.

[0076] In the above embodiment, the biological information acquired by the portable medical device 2, 2A is transmitted from the receiving device 6 to the second communication device 5 via a communication network installed in the medical facility 100. However, the path by which the biological information is transmitted from the portable medical device 2, 2A to the second communication device 5 is not limited to this. For example, the biological information acquired by the portable medical device 2, 2A may be transmitted from the receiving device 6 to the second communication device 5 via wireless communication. Furthermore, the biological information acquired by the portable medical device 2 may be transmitted to the second communication device 5 via the antenna 10, the antenna network 7, and the communication cable 9 shown by the dashed line in FIG. 1. Furthermore, for example, the biological information acquired by the portable medical device 2A may be transmitted to the second communication device 5 via the access point AP, the in-hospital network 70, and the communication cable 9 shown by the dashed line in FIG. 8.

[0077] In the above embodiment, the display image based on the display data D2 displays the measurement results on three different dates in chronological order, but the arrangement of the measurement results on three different dates is not limited to this.

[0078] In the above embodiment, the display image based on the display data D2 displays measurement results on three different dates, but measurement results on two or four or more different dates may also be displayed.

[0079] In the above embodiment, STEP03 is executed after STEP01 and STEP02 are executed, but it may be executed before STEP01 and STEP02 are executed.

[0080] In the above embodiment, user U inputs the measurement location and measurement time after finishing measuring the signal strength in each room, but the measurement location and measurement time may also be input when starting to measure the signal strength in each room.

[0081] In the above embodiment, STEP 02 does not have to be executed. In this case, for example, in STEP 06, the user U causes the display unit of the first communication device 3 to display the map illustrated in Fig. 4 and touches a position on the map corresponding to the measurement position, thereby inputting the measurement position and measurement time when starting to measure the signal strength in each room.

[0082] In the above embodiment, STEP 12 may not be executed.

[0083] In the above embodiment, each room is assigned a room number, but the user U may assign each room a serial number different from the room number. In this case, the user U inputs the serial number into the input unit of the first communication device 3, for example, before STEP 04 is executed. The first communication device 3 stores serial number information related to the serial number in the memory of the first communication device 3 based on the input operation by the user U. As a result, in STEP 08, measurement position information including the serial number information is transmitted to the second communication device 5. In this case, the serial number information can function as position identification information.

[0084] In the above embodiment, two predetermined values ​​(a first predetermined value indicating a warning and a second predetermined value indicating a caution) are set, but only one of the predetermined values ​​may be set, or three or more predetermined values ​​may be set.
