Japanese Patent Application Laid-Open No. 2005-177342

When biometric information is transmitted from a portable medical device such as a wireless telemeter to a central monitor, it is transmitted to the central monitor via a communication network installed within the medical facility, such as an antenna network or an in-hospital network within the hospital. Therefore, to properly transmit biometric information to the central monitor, it is necessary to regularly manage 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 someone who patrols the hospital carrying the portable medical device and a transmitter, and someone 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 done by one person, and there is room for improvement in this regard.

The present disclosure aims to provide a signal strength monitoring system, signal strength monitoring method, computer program, and storage medium that can efficiently monitor the signal strength of communication networks within medical facilities with a small number of personnel.

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.

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.

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.

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

In the signal strength monitoring system configured as described above, 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 that associates 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 emitted from multiple radio wave transmitters installed within the medical facility, and the integrating device generates integrated information that associates the measurement location information with the signal strength information. Therefore, a single user can obtain the information necessary to monitor the signal strength of the communication network within the medical facility. Therefore, the signal strength monitoring system configured as described above allows for efficient monitoring of the signal strength of the communication network within the medical facility with a small number of personnel. Furthermore, the signal strength monitoring method, computer program, and storage medium configured as described above can also achieve similar effects.

This disclosure provides a signal strength monitoring system, signal strength monitoring method, computer program, and storage medium that can efficiently monitor the signal strength of communication networks within medical facilities with a small number of personnel.

An example of an embodiment of the present disclosure will be described below with reference to the drawings.

(First embodiment)
A signal strength monitoring system 1 according to a first embodiment will be described with reference to FIGS. 1 and 2 . FIG. 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 FIG. 4 ). A plurality of antennas 10 (examples of radio wave transmitters) are installed in the medical facility 100. Note that, for convenience of explanation, only one antenna 10 is illustrated in FIG. 1 . As illustrated in FIG. 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.

The portable medical device 2 can be carried by a user U traveling 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 a patient's biological information. The portable medical device 2 is configured to measure biological information of a patient, etc. Examples of biological information include blood pressure information and electrocardiogram information. The portable medical device 2 transmits the biological information to the receiving device 6 via the antenna network 7 and the communication cable 8, for example.

User U is a person who monitors the signal strength of the antenna network 7. For example, user U simulates a patient and uses a portable medical device 2 to transmit biometric information acquired from a patient within 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 shown in the example shown in Figure 1, but the signal strength monitoring system 1 may be equipped with multiple portable medical devices 2. In this case, for example, each of the multiple users U carries a portable medical device 2 and patrols the medical facility 100.

When transmitting acquired biometric information, the portable medical device 2 emits radio waves according to a specified channel toward the antenna 10. The emitted 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 Figure 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 the frequency band and corresponds to the frequency used. In the example shown in Figure 2, the frequency used is 425.1 MHz, and the channel is 2050.

Returning to Figure 1, the first communication device 3 will now be described. The first communication device 3 is, for example, a terminal device portable by the user U, such as a tablet terminal, smartphone, or 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 ROM (Read Only Memory) in which various computer programs are stored, and a RAM (Random Access Memory) having multiple work areas in which various computer programs executed by the processor are stored. The memory of the first communication device 3 may also store map information related to a map of the medical facility 100 and grid map information, which will be described later. The processor may include, for example, at least one of a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and a GPU (Graphics Processing Unit). The CPU may be composed of multiple CPU cores. The GPU may be composed of multiple GPU cores. The processor is configured, for example, to load a specified computer program from various computer programs stored in ROM onto RAM and execute various processes in cooperation with the RAM.

The first communication device 3 can transmit measurement location information and time information (an example of time axis information) to the second communication device 5, for example, via wireless communication. The measurement location information is information regarding the location where the user U measured the signal strength (hereinafter also referred to as the measurement location). The measurement location corresponds, for example, to the location where the user U measured the patient's biometric information using the portable medical device 2. The measurement location information includes location identification information associated with the location within the medical facility 100. The location identification information includes, for example, room number information regarding the room numbers assigned to each room within the medical facility 100, coordinate information for identifying the locations of rooms within the medical facility 100 and each point within the medical facility 100 on a grid map (described below), and area information such as area numbers assigned to each area within the medical facility 100. The user U can use the location identification information to identify the measurement location on a map of the medical facility 100. The measurement location information can also be used to identify multiple areas covered by multiple antennas 10 installed in the medical facility 100. The time information is information about the time when the user U was present at the location where the signal strength was measured (measurement location). The time when the user U was present at the measurement location 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 location information and 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 below). However, the first communication device 3 may also acquire the measurement location information and time information by, for example, the user U inputting the measurement location and measurement time into an input unit (not shown) of the first communication device 3.

The spectrum analyzer 4 is communicatively connected to the portable medical device 2 via the antenna network 7 and the communication cable 8. The spectrum analyzer 4 is communicatively connected to the second communication device 5 via the communication cable 11. The spectrum analyzer 4 obtains 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 on the spectrum analyzer 4.

The second communication device 5 is a terminal device such as a tablet terminal, smartphone, or 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 the areas covered by each of the multiple antennas 10. The coverage area information is, for example, table information that associates 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), which 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.

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

In this embodiment, a computer-readable medium may be used. A computer-readable medium refers to any type of physical memory (RAM, ROM, etc.) capable of storing 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). Examples of non-transitory computer-readable media include magnetic recording media (e.g., floppy disks, magnetic tape, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R/Ws, and semiconductor memories (e.g., mask ROMs, programmable ROMs (PROMs), erasable PROMs (EPROMs), and flash ROMs).

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 Figure 4). The receiving device 6 receives biological information from the portable medical device 2 via the antenna network 7 and the 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.

The antenna network 7 is configured to use multiple antennas 10 to transmit, for example, various types of information to the spectrum analyzer 4 and the receiving device 6.

Next, with reference to Figures 3 to 7, a signal strength monitoring method executed by the signal strength monitoring system 1 will be described. 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 within a medical facility 100, as illustrated in Figures 4 and 5, and monitors the signal strength of multiple antennas 10 installed in the medical facility 100. The numbers assigned to each room indicate the room number of each room. 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 the 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.

As illustrated in FIG. 3, user U saves map information of the medical facility 100 in the first communication device 3 (STEP 01). For example, user U saves 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 on a server within the medical facility 100 to the first communication device 3. However, user U may also save 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 on 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 staff station 106. Area A2 includes first day room 108 and machine room 109. Area A3 includes patient rooms 104 to 105, nurse station 107, lounge 110, equipment room 111, shower room 113, and men's changing room 114. Area A4 includes work corner 112, rest room 115, women's changing room 116, and second day room 117.

As illustrated in FIG. 3, the user U performs an input operation on the input unit of the first communication device 3 to overlay 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). Note that in this embodiment, the grid map based on the grid map information is the map illustrated in FIG. 5.

As shown in FIG. 5, the grid map includes coordinates consisting of seven rows (rows 1 to 7) and 11 columns (columns A to K). Note that while the coordinates shown in FIG. 5 are grid-like coordinates, they may also be point-like coordinates, for example. Furthermore, the shape of the grid is not limited to squares and may be other shapes such as rectangles or circles. In this embodiment, each room is treated as being located at the coordinates where the majority or main part of it is located. For example, since the majority of hospital room 101 is located in grid C1, it is considered to be located in grid C1. Staff station 106 is considered to be located in grid A2, which includes the installation position of antenna 10F and measurement position P6.

As illustrated in FIG. 3, user U synchronizes the time on the first communication device 3 with the time on the spectrum analyzer 4 (STEP 03). Specifically, user U, for example, accesses an NTP (Network Time Protocol) server to synchronize the time on the first communication device 3, and then verifies that the time on the first communication device 3 and the time on the spectrum analyzer 4 match. If the time on the first communication device 3 and the time on the spectrum analyzer 4 do not match, user U synchronizes the time on the spectrum analyzer 4 to the time on the first communication device 3.

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

The portable medical device 2 transmits the biometric information to the receiving device 6 via the antenna 10A, the antenna network 7, and the communication cable 8. The receiving device 6 then transmits the received biometric information to the second communication device 5, for example, via a communication network installed within the medical facility 100. However, the timing at which the receiving device 6 transmits the biometric information to the second communication device 5 is arbitrary. That is, the receiving device 6 may transmit the received biometric information to the second communication device 5 sequentially, or may transmit the received biometric 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 biometric 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 biometric 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.

The spectrum analyzer 4 analyzes the radio signal received by the antenna 10A to obtain signal strength information from 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, based on the analysis results, obtains signal strength information regarding the signal strength from the antenna 10A corresponding to the measurement time at the measurement position P1.

When user U has finished measuring the signal strength of antenna 10A in hospital room 101, he or she displays a grid map on the display unit of first communication device 3 and touches a position on the grid map that corresponds to the measurement position, thereby inputting the measurement position and measurement time (STEP 06). However, user U may also display a map such as the example shown in FIG. 4 on the display unit of first communication device 3 and input the measurement position and measurement time by touching a position on the map that corresponds to the measurement position. User U may also input the measurement position and measurement time into an input unit provided on first communication device 3.

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 on 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, if there is no input operation by the user U for a predetermined period of time or more. If the signal strength measurement is to be ended (YES in STEP 07), proceed to STEP 08. If the signal strength measurement is not to be ended (NO in STEP 07), return to STEP 04. In this embodiment, signal strength is also measured in hospital rooms 102 to 105, staff station 106, and nurse station 107 (NO in STEP 07), so return to STEP 04. Therefore, user U moves to hospital room 102 to hospital room 105, staff station 106, and nurse station 107, and repeats steps 04 to 06.

Here, we will explain the measurement of signal strength in hospital room 102. Hospital room 102 is covered by antennas 10A and 10B. As illustrated in Figure 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 biometric information acquired by portable medical device 2 be transmitted from portable medical device 2 to receiving device 6 via antenna 10B. Therefore, in this embodiment, the biometric 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 the measurement of signal strength in hospital rooms 103 to 105, staff station 106, and nurse station 107 is similar to the measurement of signal strength in hospital room 101, and therefore will not be described here. However, when measuring signal strength at the staff station 106 and nurse station 107, a pseudo signal may be transmitted from the portable medical device 2 to the receiving device 6 via antennas 10F and 10G.

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

Next, the user U performs an input operation on the 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 also 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.

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

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

The second communication device 5 associates the signal strength information and the biometric information based on the time information (STEP 12).

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 location information, time information, and signal strength information (STEP 13). A display image based on display data D1 is, for example, the display image illustrated in FIG. 6. Display data D1 includes information about the room in which the signal strength measurement was performed, information about the area to which each room belongs, information about the square on the map to which each room belongs, measurement location 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 location P1 at 15:30, and the signal strength was 48 dB.

In STEP 13, the second communication device 5 determines whether the signal strength is below a predetermined value for each of measurement positions P1 to P7 in the medical facility 100 based on the measurement position information and 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 severity of a caution is less severe than the severity of a warning.

The measurement results in this embodiment are as shown in Figure 6. Therefore, the second communication device 5 determines that the signal strength at measurement positions P1 to P2 and measurement positions P6 to P7 is 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 less than the second predetermined value. The second communication device 5 determines that the signal strength at measurement positions P3 and P5 is 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 less than the second predetermined value, signal strength information whose signal strength is 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 Figure 6, signal strengths whose signal strength is less than the first predetermined value are hatched vertically. Signal strengths whose signal strength is greater than the first predetermined value but is less than the second predetermined value are hatched horizontally. Note that the method of distinguishing between the signal strength information is not limited to hatching. For example, different colors may be used for signal strength portions where the signal strength is equal to or less than a first predetermined value and signal strength portions where the signal strength exceeds the first predetermined value but is equal to or less than a second predetermined value.

The second communication device 5 can also generate display data D2 (see Figure 7) that displays signal strength information for each measurement position P1 to P7 in the medical facility 100 based on measurement location information, time information, and signal strength information generated multiple times on different dates. A display image based on display data D2 is the display image shown in Figure 7. The display image shown in Figure 7 chronologically displays measurement results for January 12, 2021, February 21, 2021, and March 22, 2021. In other words, the display image shown in Figure 7 chronologically displays measurement results for three different dates. Note that the display "N/A" in the display image shown in Figure 7 indicates that no signal strength measurement was performed. Furthermore, the display data D2 includes distinction information for distinguishing between, 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 shown in the example in Figure 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 exceeds the first predetermined value but is equal to or less than the second predetermined value are hatched with horizontal lines.

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 exceeds 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 exceeded 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 taken 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.

The second communication device 5 can also generate display data for displaying the signal strength information and biometric information associated based on the time information, for example, on a display unit (not shown) provided on 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, with the biometric information associated based on the time information additionally displayed. The added biometric information can be selected as appropriate by the user U. By visually checking the display image based on the display data displayed on the display unit provided on the first communication device 3 or the second communication device 5, the user U can see the biometric information and the signal strength at the time the biometric information was measured. The display screen may also display a link for displaying biometric information (e.g., an electrocardiogram waveform), or may display a noise level calculated from the biometric information, etc.

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 with 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 emitted from multiple antennas 10 installed within the medical facility 100, the second communication device 5 generates integrated information associating the measurement location information with 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.

Furthermore, with the signal strength monitoring system 1 configured as described above, the portable medical device 2 and the spectrum analyzer 4 are separate devices. Therefore, the user U can use the portable medical device 2 with a simple configuration to monitor the signal strength of the antenna network 7 within the medical facility 100.

Furthermore, according to the signal strength monitoring system 1 configured as described above, the second communication device 5 is a device separate from the portable medical device 2, the first communication device 3, and the spectrum analyzer 4, and therefore the configuration of the second communication device 5 can be simplified.

Furthermore, with the signal strength monitoring system 1 configured as described above, the user U can identify which portable medical device 2 transmitted the biometric information by using the channel information as identification information for distinguishing between the portable medical device 2 and other portable medical devices. Therefore, even if, for example, 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.

Furthermore, with the signal strength monitoring system 1 configured as described above, 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 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.

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

Furthermore, with the signal strength monitoring system 1 configured as described above, the user U can accurately identify measurement positions P1 to P7 on a map. In particular, in this embodiment, the location identification information includes coordinate information, so 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.

Furthermore, with the signal strength monitoring system 1 configured as described above, the second communication device 5 determines whether the signal strength is below 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 results from the second communication device 5, the user U can easily identify locations where the signal strength is below a predetermined value.

Furthermore, according to the signal strength monitoring system 1 configured as described above, the second communication device 5 generates display data D2. The display image based on the display data D2 displays measurement results for three different dates in chronological order. Therefore, by using the display data D2, the user U can easily understand the changes in signal strength at each point (measurement positions P1 to P7).

Furthermore, according to the signal strength monitoring system 1 configured as described above, the display data D1 and the display data D2 include distinction information. Therefore, by using the distinction information, the user U can easily distinguish, among the multiple pieces of signal strength information displayed, between signal strength information whose signal strength is below a predetermined value and signal strength information whose signal strength is above the predetermined value.

Furthermore, according to the signal strength monitoring system 1 configured as described above, the second communication device 5 associates the signal strength information and the biometric information based on time information. The second communication device 5 generates display data for displaying the associated signal strength information and the 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 signal strength information and the biometric information, which are associated 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.

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 biometric information acquired by the portable medical device 2A is transmitted to a receiving device 6 via an access point AP (an example of a radio wave transmitter) and an in-hospital network (an example of a communication network within a medical facility) 70. In this embodiment, the signal strength monitoring system 1A executes the signal strength monitoring method illustrated in FIG. 3 .

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.

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 the hospital network 70. While only one access point AP is shown in the example shown in FIG. 8 for convenience of explanation, in this embodiment, multiple access points AP are installed instead of antennas at the locations of antennas 10A-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 the process in which a communication terminal connected to an access point maintains a network connection by initiating a communication connection with another access point when the communication terminal moves out of the communication connection range of the currently connected access point. However, the portable medical device 2A may also initiate roaming, for example, when the signal strength of the currently connected access point falls below a predetermined value. In this case, the portable medical device 2A will connect to the access point AP with the strongest signal strength when roaming begins.

By communicating with the access point AP, the portable medical device 2A acquires RSSI (Received Signal Strength Indicator) information (an example of signal strength information) indicating the signal strength of the access point AP with which it 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 the process of writing various information to memory. In other words, the portable medical device 2A stores various information, such as RSSI information, in its own memory. The user U can transmit the various 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) included in the portable medical device 2A to transmit the various information stored in the memory of the portable medical device 2A to the second communication device 5.

The hospital network 70 is, for example, an IP network installed within a medical facility. The hospital network 70 is configured to transmit, for example, biological information, etc. 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 in a repeater hub and decoding the headers of Ethernet® frames at the data link layer.

Next, we will explain the signal strength monitoring method executed by the signal strength monitoring system 1A. The signal strength monitoring system 1A executes the signal strength monitoring method illustrated in Figure 3. Steps 01 and 02 are the same as in the first embodiment.

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 the NTP server to synchronize the time on the first communication device 3, and then confirms that the time on the portable medical device 2A and the time on the first communication device 3 match. If the time on the portable medical device 2A and the time on the first communication device 3 do not match, the user U synchronizes the time on the portable medical device 2A with the time on the first communication device 3.

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

When transmitting biometric 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. In other words, the portable medical device 2A acquires signal strength information of the access point AP with which it is communicating (STEP 05). Note that this 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 time information, channel information, and RSSI information.

STEP 06 to STEP 08 are the same as in the first embodiment. However, in this embodiment, roaming is performed, so if the signal strength measurement is not terminated (NO in STEP 07), the portable medical device 2A will connect to the most appropriate access point AP for transmitting biological information simply by the user U 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 traveling around the predetermined measurement positions (measurement positions P1 to P7) within the medical facility 100.

The user U operates the 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, via wireless communication (STEP 09). In this way, the second communication device 5 acquires the RSSI information.

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

The signal strength monitoring system 1A, signal strength monitoring method, computer program, and non-transitory computer-readable medium on which the computer program is stored, configured as described above, can also achieve the same effects as the first embodiment.

Furthermore, with the signal strength monitoring system 1A configured as described above, the portable medical device 2A can acquire RSSI information. Therefore, the user U can monitor the signal strength of the in-hospital network 70 within the medical facility 100 without having to prepare a spectrum analyzer.

The above embodiments are intended to facilitate understanding of the present disclosure and are not intended to limit the present disclosure. This disclosure may be modified or improved without departing from its spirit.

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, for example, transmit measurement location information and sequence information (an example of time axis information) relating to the measurement order of the measurement locations to the second communication device 5. The sequence information is information for identifying the temporal relationship between the measurements of signal strength at each measurement location. The sequence 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 measurement order, symbol information relating to symbols indicating the measurement order, etc.

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. In other words, 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 having to prepare a second communication device 5.

In the above embodiment, the biometric 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 within the medical facility 100. However, the path by which the biometric information is transmitted from the portable medical device 2, 2A to the second communication device 5 is not limited to this. For example, the biometric 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 biometric 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 biometric 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.

In the above embodiment, the display image based on display data D2 displays 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.

In the above embodiment, the display image based on 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.

In the above embodiment, STEP 03 is executed after STEP 01 and STEP 02 are executed, but it may also be executed before STEP 01 and STEP 02 are executed.

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

In the above embodiment, STEP 02 does not have to be executed. In this case, for example, in STEP 06, the user U displays the map shown in FIG. 4 on the display unit of the first communication device 3, and touches a position on the map that corresponds to the measurement position, thereby inputting the measurement position and measurement time when starting to measure the signal strength in each room.

In the above embodiment, STEP 12 does not need to be performed.

In the above embodiment, each room is assigned a room number, but the user U may assign each room a serial number that is different from the room number. In this case, the user U inputs the serial number into the input section 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 its memory based on the input operation by the user U. As a result, in STEP 08, measurement location information including the serial number information is transmitted to the second communication device 5. In this case, the serial number information can function as location identification information.

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.
