Description

The present invention relates to a temperature measurement system, an information processing device, and a program.

There is a known temperature measurement system that measures a user's body temperature using a measuring device that measures the surface temperature of an object without contact. Since the user does not come into contact with the measuring device, such a temperature measurement system prevents viruses, bacteria, etc. from attaching to the body, thereby protecting the user's health.

There are also known temperature management systems that measure the body temperature of users and manage the body temperature of each user. Such temperature management systems record the body temperature of each user by associating the measured body temperature with user information recorded, for example, on an IC card held by the user.

Patent document 1 discloses a body temperature analysis device that measures the body temperatures of multiple people at once without a thermometer, identifies each of the people using location information, and detects abnormalities in the body temperature of specific subjects. Patent document 1 also describes how body temperature can be associated with personal information.

Patent document 2 describes a system in which a wearable device measures body temperature data. In the system described in Patent document 2, a mobile communication terminal reads employee information from an IC card via short-range wireless communication, obtains body temperature data from the wearable device, and transmits a message including the employee information and body temperature data to a safety confirmation system.

However, in a temperature measurement management system using an IC card, the user must contact the IC card with a card reading device to read the information recorded on the IC card. For this reason, even if such a temperature measurement management system measures the user's body temperature using a non-contact measuring device, there is a possibility that the user may come into contact with the card reading device. Furthermore, such a temperature measurement management system may require the user to operate a touch panel or the like after the card reading device reads the information recorded on the IC card. In such cases, the user also comes into contact with the touch panel. Therefore, in such a temperature measurement system, there is a possibility that the user may come into contact with the card reading device or touch panel, etc., and viruses, bacteria, etc. may adhere to the body.

The present invention has been made in consideration of the above problems, and aims to provide a temperature measurement system, information processing device, and program that can acquire body temperature and identification information without contact, and can associate and manage body temperature and identification information without error.

In order to solve the above-mentioned problems and achieve the object, the temperature measuring system of the present invention comprises a mobile transmitting device that is held by a user and transmits uniquely assigned identification information via wireless communication; a temperature measuring device that measures the user's body temperature non-contact; a receiving device that receives the identification information from the mobile transmitting device via the wireless communication; an identification information acquisition unit that acquires the identification information from the receiving device; a body temperature acquisition unit that acquires the body temperature from the temperature measuring device; an association unit that associates the body temperature with specified identification information, which is the identification information received within a specified time range relative to the measurement time when the body temperature was measured; and a shielding device that blocks the receiving device from receiving wireless communication signals transmitted from a device located outside the measurement area in which the body temperature can be measured by the temperature measuring device .

According to the present invention, body temperature and identification information can be obtained without contact, and body temperature and identification information can be associated and managed without error.

FIG. 3 is a sequence diagram showing the flow of transfer of identification information. FIG. 4 is a flowchart showing the flow of processing by the information processing device. FIG. 5 is a diagram illustrating a hardware configuration of the information processing device.

Figure 1 is a diagram showing a temperature measurement system 10 according to an embodiment. The temperature measurement system 10 measures the body temperature of a user and manages the measured body temperature in association with the user. For example, the temperature measurement system 10 is installed in a company or the like, measures the body temperature of employees who are users, and manages the measured body temperature in association with identification information that identifies the employee.

The temperature measurement system 10 includes a mobile transmitting device 20, a temperature measuring device 22, a receiving device 24, a relay device 26, a shielding device 28, and an information processing device 30.

The mobile transmitting device 20 is held by a user. For example, the user holds the mobile transmitting device 20 that has been assigned to the user. The mobile transmitting device 20 is a small device that the user can hold in his/her hand. For example, the mobile transmitting device 20 is attached to a neck strap. For example, the user holds the mobile transmitting device 20 by putting the neck strap to which the mobile transmitting device 20 is attached around the user's neck.

The mobile transmitting device 20 is, for example, a beacon tag for BLE (Bluetooth (registered trademark) Low Energy) communication. Note that the mobile transmitting device 20 may be an RFID tag or a device that transmits information by other wireless methods.

The mobile transmitting device 20 stores uniquely assigned identification information and transmits the stored identification information via wireless communication. The unique identification information is managed, for example, by a user management device that manages user information, in association with user information that identifies the user who holds the mobile transmitting device 20.

The mobile transmitting device 20 periodically, for example at regular time intervals, broadcasts the identification information to the surrounding area via wireless communication. The mobile transmitting device 20 transmits the identification information with a radio wave strength sufficient to reach a predetermined distance range, for example a range of several meters. Therefore, the identification information transmitted from the mobile transmitting device 20 can be received by devices within the predetermined distance range, but cannot be received by devices outside the predetermined distance range.

The temperature measuring device 22 measures the user's body temperature in a non-contact manner. For example, the temperature measuring device 22 measures the surface temperature of the user's skin as the body temperature. For example, the temperature measuring device 22 is an infrared thermometer that uses a thermal pixel sensor.

The temperature measuring device 22 is fixedly installed at a predetermined position. For example, when measuring the body temperature of employees, the temperature measuring device 22 is installed at the entrance of the company, etc.

When the user approaches a measurement area where the body temperature can be measured, the temperature measuring device 22 measures the user's body temperature in a non-contact manner. When the temperature measuring device 22 measures the user's body temperature, it transmits the body temperature and the measurement time indicating the time when the body temperature was measured to the information processing device 30. Note that the temperature measuring device 22 does not have to transmit the measurement time.

The receiving device 24 receives the identification information transmitted by wireless communication from the mobile transmitting device 20. In this embodiment, the receiving device 24 is a gateway for BLE communication.

The receiving device 24 is fixedly installed at a predetermined position. The receiving device 24 can receive identification information from a mobile transmitting device 20 located within a predetermined distance from the position where the receiving device 24 is installed, but cannot receive identification information from a mobile transmitting device 20 outside the predetermined distance range. Therefore, when the receiving device 24 receives identification information, the user management device or the like can detect the user's moving position based on the position of the receiving device 24 that received the identification information and the user information associated with the identification information.

The receiving device 24 is connected to the information processing device 30 via a predetermined network. The receiving device 24 may be connected to the receiving device 24 via a relay device 26, or may be connected to the receiving device 24 without via the relay device 26. When the receiving device 24 receives identification information from the mobile transmitting device 20, it transmits to the information processing device 30 the received identification information, the radio wave intensity of the wireless communication signal including the identification information, the receiving device identification information uniquely assigned to the receiving device 24, and the reception time indicating the time when the identification information was received. Note that the receiving device 24 does not have to transmit the reception time.

Here, the receiving device 24 is fixedly installed near the temperature measuring device 22. For example, when the user is located within a measurement area where the body temperature can be measured by the temperature measuring device 22, the receiving device 24 is installed in a position where it can receive a wireless communication signal transmitted from the mobile transmitting device 20 held by the user with a radio wave intensity equal to or greater than a predetermined threshold.

The receiving device 24 may transmit, from among the received identification information, identification information whose radio wave strength is equal to or greater than a preset threshold to the information processing device 30. That is, the receiving device 24 may delete, from among the received identification information, identification information whose radio wave strength is less than the threshold. This allows the receiving device 24 to transmit, to the information processing device 30, identification information transmitted from a mobile transmitting device 20 held by a user located within a predetermined distance. That is, the receiving device 24 can prevent identification information transmitted from a mobile transmitting device 20 held by a user located farther than the predetermined distance from being transmitted to the information processing device 30.

The shielding device 28 is a plate that blocks wireless communication signals. For example, the shielding device 28 is a plate that blocks electromagnetic waves. The shielding device 28 blocks wireless communication signals transmitted from a mobile transmitting device 20 that is located outside the measurement area where the body temperature can be measured by the temperature measuring device 22, so that the receiving device 24 cannot receive the signals.

Note that the shielding device 28 does not have to be able to shield wireless communication signals from all mobile transmitting devices 20 located outside the measurement area, so long as the shielding device 28 is arranged so that wireless communication signals transmitted from mobile transmitting devices 20 held by users located within the measurement area can be received by the receiving device 24. For example, the shielding device 28 is arranged so as not to shield wireless communication signals transmitted from within a specified angle range centered on the detection direction of the temperature measuring device 22, but to shield wireless communication signals transmitted from outside the specified angle range.

The relay device 26 transfers the identification information received by the receiving device 24 to the information processing device 30. The relay device 26 may receive the identification information from the receiving device 24 via wireless communication, or may receive the identification information via wired communication. When the relay device 26 receives the identification information from the receiving device 24 via wireless communication, it may receive the identification information via a method different from the wireless communication method between the mobile transmitting device 20 and the receiving device 24.

The information processing device 30 is a computer or the like. The information processing device 30 may be a server on a network, or may be a cloud in which multiple servers on a network operate in cooperation with each other. When the temperature measuring device 22 measures the user's body temperature, the information processing device 30 acquires the body temperature and the measurement time from the temperature measuring device 22. Note that when the measurement time is not transmitted from the temperature measuring device 22, the information processing device 30 identifies the time when the body temperature was acquired as the measurement time.

In addition, when the receiving device 24 receives identification information from the mobile transmitting device 20, the information processing device 30 acquires from the receiving device 24 the received identification information, the radio wave intensity of the wireless communication signal including the identification information, the receiving device identification information, and the reception time. When the reception time is not transmitted from the receiving device 24, the information processing device 30 identifies the time at which the identification information was acquired as the reception time. Then, the information processing device 30 manages the measured body temperature in association with the identification information of the mobile transmitting device 20 held by the user.

Figure 2 is a diagram showing the functional configuration of the information processing device 30. The information processing device 30 has an identification information acquisition unit 42, an identification information storage unit 44, a body temperature acquisition unit 46, an association unit 48, and an output unit 50.

The identification information acquisition unit 42 acquires the identification information each time the identification information is transmitted from the receiving device 24. In this case, the identification information acquisition unit 42 acquires the radio wave strength, the receiving device identification information, and the reception time along with the identification information. Then, each time the identification information acquisition unit 42 acquires the identification information, the radio wave strength, the receiving device identification information, and the reception time are stored in the identification information storage unit 44. Note that the identification information acquisition unit 42 does not need to acquire the reception time. In this case, the identification information acquisition unit 42 stores the time when the identification information was acquired from the receiving device 24 as the reception time in the identification information storage unit 44.

The identification information storage unit 44 stores, for example, a list of combinations of identification information, radio wave intensity, receiving device identification information, and reception time.

The body temperature acquisition unit 46 acquires the body temperature and the measurement time from the temperature measuring device 22. The body temperature acquisition unit 46 outputs the acquired body temperature and the measurement time to the association unit 48. Note that the body temperature acquisition unit 46 does not need to acquire the measurement time from the temperature measuring device 22. In this case, the body temperature acquisition unit 46 outputs the time when the body temperature was acquired from the temperature measuring device 22 as the measurement time.

When the association unit 48 acquires the body temperature and the measurement time, it extracts, from the identification information stored in the identification information storage unit 44, the specified identification information, which is the identification information received within a specified time range relative to the measurement time when the body temperature was measured. Then, the association unit 48 associates the body temperature with the specified identification information, which is the identification information received within a specified time range relative to the measurement time when the body temperature was measured.

In addition, when there are two or more pieces of specified identification information and the two or more pieces of specified identification information include identification information with different information content, the association unit 48 may calculate an average radio wave intensity, which is the average of the radio wave intensity, for each of the specified identification information with the same information content. Then, the association unit 48 may associate the body temperature with the maximum strength identification information, which is the identification information with the maximum average radio wave intensity. Furthermore, when there are two or more pieces of maximum strength identification information, the association unit 48 may associate the body temperature with the maximum number identification information, which has the largest number of identification information received within a specified time range, among the two or more pieces of maximum strength identification information. In this case, when there are two or more pieces of maximum number identification information, the association unit 48 may further associate the body temperature with the most recent identification information, which is the identification information closest to the measurement time among the two or more pieces of maximum number identification information.

The output unit 50 outputs the body temperature and the identification information associated by the association unit 48 to user management information, etc. The user management device, for example, manages the identification information of the mobile transmitting device 20 in association with user information that identifies the user who holds the mobile transmitting device 20. Therefore, the user management device can identify the user's body temperature by acquiring the associated body temperature and identification information.

Figure 3 is a sequence diagram showing the flow of transfer of identification information in the temperature measurement system 10. The mobile transmitting device 20 periodically broadcasts the identification information by wireless communication. When the receiving device 24 receives the identification information, the temperature measurement system 10 executes processing according to the flow shown in Figure 3.

First, in S11, the mobile transmitting device 20 transmits identification information via wireless communication. Then, the receiving device 24 receives the identification information transmitted from the mobile transmitting device 20.

Next, in S12, the receiving device 24 detects the radio wave strength of the wireless communication signal including the identification information, for example, a received signal strength indicator (RSSI). The receiving device 24 may detect the radio wave strength expressed at a level separated by a predetermined number of steps, for example, at four levels.

Next, in S13, the receiving device 24 identifies the reception time, which is the time when the identification information was received. Note that, if the information processing device 30 identifies the reception time, the receiving device 24 does not need to identify the reception time.

Next, in S14, the receiving device 24 selects, from among the identification information, identification information whose radio wave strength is equal to or greater than the threshold as the identification information to be transmitted, and deletes identification information whose radio wave strength is less than the threshold. Next, in S15, the receiving device 24 transmits to the relay device 26 a set of the identification information, radio wave strength, receiving device identification information, and reception time for the identification information selected as the identification information to be transmitted. Next, in S16, the relay device 26 transfers the set of the identification information, radio wave strength, receiving device identification information, and reception time received from the receiving device 24 to the information processing device 30. Then, in S17, the information processing device 30 stores the set of the identification information, radio wave strength, receiving device identification information, and reception time received from the relay device 26. In this way, the temperature measurement system 10 executes the processes from S11 to S17 each time the receiving device 24 receives the identification information transmitted from the mobile transmitting device 20.

Figure 4 is a flowchart showing the processing flow of the information processing device 30. When the information processing device 30 acquires body temperature from the temperature measuring device 22, it executes the processing flow shown in Figure 4.

First, in S20, the information processing device 30 extracts, from the stored identification information, one or more pieces of specified identification information that are identification information received within a specified time range relative to the measurement time when the body temperature was measured. For example, the information processing device 30 extracts one or more pieces of specified identification information received within a specified time range by searching for the reception times stored in the identification information storage unit 44.

The specified time range is, for example, a predetermined time range before and after the measurement time. For example, the specified time range is a range from 5 seconds before the measurement time to 3 seconds after the measurement time. If the specified time range includes a time after the measurement time, the information processing device 30 executes the processing of this step after a certain time has elapsed from the measurement time.

Next, in S21, the information processing device 30 determines whether there are two or more pieces of specified identification information, which are identification information received within a specified time range, and whether the two or more pieces of specified identification information include identification information with different information content. If there is only one piece of specified identification information, or if the two or more pieces of specified identification information do not include identification information with different information content (No in S21), the information processing device 30 proceeds to S22. If there are two or more pieces of specified identification information, and the two or more pieces of specified identification information include identification information with different information content (Yes in S21), the information processing device 30 proceeds to S23.

In S22, the information processing device 30 associates the acquired body temperature with the specified identification information, which is the identification information received within a specified time range relative to the measurement time. After completing S22, the information processing device 30 advances the process to S32.

In S23, the information processing device 30 calculates the average radio wave strength for each of two or more pieces of predetermined identification information having the same information content. In other words, the information processing device 30 calculates the average radio wave strength of the identification information received within a predetermined time range for each mobile transmission device 20.

Next, in S24, the information processing device 30 identifies the maximum strength identification information, which is the identification information with the maximum average radio wave strength, from among the two or more predetermined identification information. The identification information with the maximum radio wave strength may be, for example, the identification information with the highest level among the levels in which the radio wave strength is divided into a predetermined number of stages. Note that when there are two or more types of maximum strength identification information due to the same average radio wave strength, the information processing device 30 identifies two or more maximum strength identification information.

Next, in S25, the information processing device 30 determines whether or not there are two or more pieces of maximum strength identification information.

If there are not two or more pieces of maximum strength identification information, i.e., there is only one piece of maximum strength identification information (No in S25), the information processing device 30 proceeds to S26. If there are two or more pieces of maximum strength identification information (Yes in S25), the information processing device 30 proceeds to S27.

In S26, the information processing device 30 associates the acquired body temperature with the maximum strength identification information. After completing S26, the information processing device 30 advances the process to S32.

In S27, the information processing device 30 identifies the maximum number identification information, among the two or more maximum strength identification information, that has the largest number of identification information received within a specified time range. Note that if there are two or more types of maximum number identification information because the numbers within the specified time range are the same, the information processing device 30 identifies two or more maximum number identification information.

Next, in S28, the information processing device 30 determines whether there are two or more pieces of maximum number identification information.

If there are two or more pieces of maximum number identification information, i.e., there is one piece of maximum number identification information (No in S28), the information processing device 30 proceeds to S29. If there are two or more pieces of maximum number identification information (Yes in S28), the information processing device 30 proceeds to S30.

In S29, the information processing device 30 associates the acquired body temperature with the maximum number identification information. After completing S29, the information processing device 30 advances the process to S32.

In S30, the information processing device 30 selects the most recent identification information, which is the identification information closest to the measurement time, from among the two or more maximum number identification information. Next, in S31, the information processing device 30 associates the acquired body temperature with the most recent identification information. After completing S31, the information processing device 30 advances the process to S32.

Then, in S32, the information processing device 30 outputs the associated body temperature and identification information to user management information, etc. When the processing of S32 is completed, the information processing device 30 ends this flow.

The temperature measurement system 10 according to the embodiment described above acquires the user's body temperature in a non-contact manner, and also acquires identification information in a non-contact manner from the mobile transmitting device 20 held by the user. The temperature measurement system 10 then associates the body temperature with the identification information based on the time the body temperature was measured in a non-contact manner and the time the identification information was received. As a result, the temperature measurement system 10 according to the embodiment can acquire the body temperature and identification information in a non-contact manner, and can associate and manage the body temperature and identification information without error.

The auxiliary storage device 306 is a rewritable storage device such as a semiconductor storage medium such as a flash memory, or a magnetically or optically recordable storage medium. The auxiliary storage device 306 stores programs used to control the information processing device 30.

The program executed by the information processing device 30 is provided by, for example, being stored on a computer connected to a network such as the Internet and being downloaded via the network. In addition, the program executed by the information processing device 30 may be provided by being pre-installed in a portable storage medium or the like.

The CPU 301 reads out such a program from a storage medium or the like, and loads each of the above modules into the main memory device 305. The CPU 301 then executes such a program to function as the identification information acquisition unit 42, the body temperature acquisition unit 46, the association unit 48, and the output unit 50.
