Description

  The present invention relates to an environment measurement system, and more particularly to an environment measurement system that measures indoor environment information.

  In general, a measurement system using an environmental sensor that monitors environmental information is used to collect weather information and environmental information such as ultraviolet rays, pollen, asbestos, and radioactive substances. In these measurement systems, environmental sensors are arranged at various locations for fixed point observation, environmental information measured by the environmental sensors is periodically collected, and environmental information is stored and analyzed. Conventionally, the collection of environmental information measured by an environmental sensor of such a measurement system has been carried out by collecting personnel. However, in recent years, with the development of the Internet network and mobile phone network, a system that can automatically collect and grasp environmental information has been developed. In addition, environmental sensors have been developed that are easy to carry with the miniaturization of the sensors. Since it became possible to carry environmental sensors, it was possible to measure at any point. As a result, the number of measurement points increased and more detailed environmental information could be collected. However, when environmental information is measured by moving an environmental sensor, it is often meaningless for analysis of environmental information or the like unless the location of the measurement is known. Therefore, a measurement system has been developed in which an environmental sensor has a GPS function and stores and analyzes the environment information and the position information in association with each other.

  For example, in Patent Document 1, a vehicle is provided with an environment sensor, a GPS receiver, and a transmitter in order to create an environment distribution map of a road environment, and a receiver that receives information transmitted from a vehicle transmitter on the headquarters side. And a road environment observation system including display means for displaying an environment distribution map based on the information.

  For example, in Patent Document 2, a sensor that can measure environmental data is built in to collect environmental information, a portable terminal that can transmit the measured data, a transmission data is received, and the position of the portable terminal A sensor information network system comprising means for storing and mapping information is disclosed. In this example, there are disclosed an example in which position information of a mobile terminal is determined from a base station of a mobile phone communication network, and an example in which GPS is built in a mobile terminal and position information is acquired by GPS.

  Here, there is also a demand for accurately grasping indoor environment information. For example, when it is desired to measure the concentration and radiation dose of asbestos in each room indoors.

  However, for example, the position information in the environmental measurement system as described in Patent Document 1 and Patent Document 2 uses GPS to receive position information. Therefore, the position information is used indoors where GPS signals cannot be received. Can not. Further, the position information calculated from the base station of the mobile phone communication network can be used to some extent even indoors, but there is a problem that it is difficult to specify an accurate measurement position because the position accuracy is not high.

  For example, asbestos air concentration and radiation dose may vary greatly from room to room, so specifying the location is important. Furthermore, it is necessary to periodically measure the concentration of asbestos in buildings that have been treated to prevent asbestos from being scattered, but in conventional systems, it is necessary to accurately grasp the measurement position along with environmental information. It was difficult. In addition, it is necessary to accurately grasp the measurement position from the viewpoint of preventing impersonation such as changing the measurement position and intentionally making the measurement value appear low.

  In view of such circumstances, the present invention is intended to provide an environment measurement system capable of measuring environmental data including highly accurate position information even indoors.

  In order to achieve the above-described object of the present invention, an environment measurement system for measuring indoor environment information according to the present invention includes position information from an indoor position information transmission unit that transmits position information for detecting an indoor position. A position information receiving unit for receiving, an environment sensor for measuring environmental information of an area around the position based on the position information received by the position information receiving unit, position information received by the position information receiving unit, and an environment sensor An environment data generation unit that generates environment data associated with the environment information to be measured.

  Furthermore, the environmental measurement system of the present invention is arranged in the vicinity of the indoor position information transmitting unit, and transmits a wireless signal having a shorter transfer distance than the position information transmitted from the indoor position information transmitting unit, A short-range wireless signal receiving unit that is disposed in the vicinity of the environmental sensor and receives a wireless signal transmitted from the short-range wireless signal transmitting unit, and the short-range wireless signal transmitting unit and the short-range wireless signal receiving unit are The area around the position based on the position information received by the information receiving unit may be used to limit the area within the transfer distance of the short-range wireless signal.

  Here, the environment sensor may measure the environment information in response to the short-range wireless signal receiving unit receiving the wireless signal transmitted from the short-range wireless signal transmitting unit.

  The environmental measurement system of the present invention further includes an environmental data transmission unit that transmits environmental data generated by the environmental data generation unit to the network, and receives and stores the environmental data transmitted by the environmental data transmission unit via the network. And a data storage unit to be provided.

  The environmental sensor may measure at least one of asbestos concentration, radiation dose, temperature, humidity, atmospheric pressure, luminance, wind speed, and sound pressure.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described together with illustrated examples. FIG. 1 is a schematic configuration diagram for explaining an environment measurement system of the present invention. As shown in the figure, the environment measurement system of the present invention is mainly composed of a position information receiving unit 10, an environment sensor 20, and an environment data generating unit 30. The environment measurement system is mainly used for measuring indoor environment information, but may be used outdoors.

  The position information receiving unit 10 receives position information from the indoor position information transmitting unit 40. The indoor position information transmitter 40 transmits position information for detecting the indoor position. As position information, for example, height information may be included in addition to latitude and longitude. Further, instead of information such as latitude / longitude, it may be specific information such as which room of which room, for example, if it is an apartment. That is, the position information may be information that can grasp the position where the environmental information is measured. For example, IMES (Indoor Messaging System) can be used as the position position information receiving system. Here, IMES is a system that transmits a GPS compatible signal from a transmitter installed indoors, and is capable of accurately grasping position information even indoors where GPS signals from satellites cannot be received. is there. By using IMES, not only can location information be acquired even indoors, but since GPS-compatible signals are used, versatility is high, so the location information receiving unit 10 does not require proprietary equipment or software, and is low It can be realized at a cost. Further, since IMES can be used with basically the same specifications as GPS, position measurement can be performed seamlessly outdoors and indoors. The system that transmits and receives position information is not limited to IMES, and may be, for example, an electronic tag or an infrared beacon as long as it can grasp indoor position information. Further, the indoor position information transmitting unit 40 is not provided indoors for the environmental measurement system of the present invention, but a general one provided for transmitting indoor position information for general purposes. May be used. In the illustrated example, the indoor position information transmitting unit 40 is provided on the indoor ceiling. However, the present invention is not limited to this, and may be a position where the transmitted position information is easily received. For example, it may be arranged in another place. In the environment measurement system of the present invention, the position information from the indoor position information transmitter 40 is received by the position information receiver 10 so that the position at the time of measuring the environment information can be grasped.

  The environmental sensor 20 measures environmental information. The environment information is information for measuring the environment related to the area around the position based on the position information received by the position information receiving unit 10. Specifically, the environmental information may be information on the environment in a predetermined area around the user, such as asbestos concentration, radiation dose, temperature, humidity, atmospheric pressure, brightness, wind speed, sound pressure, etc. It ’s fine. Further, additional information other than information about the environment such as measurement time may be obtained. The environmental sensor 20 is a sensor configured to obtain such information, and a plurality of sensor units may be provided for each measurement target. The sensor may be selectable so that only the necessary sensor can be mounted by the user.

  The environmental data generation unit 30 generates environmental data. In the environmental data, the positional information received by the positional information receiving unit 10 and the environmental information measured by the environmental sensor 20 are associated with each other. The environment data generation unit 30 receives the position information of the position information receiving unit 10 and the environment information of the environment sensor 20 in order to grasp where the data is measured, and obtains the measurement position and the measurement data at that time. It is only necessary to generate linked environment data. Further, if necessary, additional information other than environmental information such as measurement time may be linked to form environmental data. Furthermore, the environment data generation unit 30 may include a storage device that stores the generated environment data. According to the environmental measurement system of the present invention, the environmental data generated in this way can be used for grasping, analyzing, managing, etc. the indoor environment.

  The operation of the environmental measurement system of the present invention configured as described above will be described with reference to, for example, a case where the asbestos concentration in a room of a building is used as an example. First, enter a room in the building and start measuring asbestos concentration. The position information receiving unit 10 receives position information by IMES and detects an indoor position. This makes it possible to grasp which room on which floor of the building is located. Then, the environmental sensor 20 measures the asbestos concentration in the area around the location of the spot. Then, the environment data generation unit 30 is used to associate the position information with the environment information. As a result, environmental data in which the measurement position is associated with the environmental information of the surrounding area is obtained.

  Here, the environmental data may be stored in a storage device, but as described below, the environmental data may be transmitted via a network. FIG. 2 is a schematic configuration diagram for explaining an example in which environment data of the environment measurement system of the present invention is transmitted via a network. In the figure, the parts denoted by the same reference numerals as those in FIG. As shown in the figure, in this example, an environmental data transmission unit 50 and a data storage unit 60 are added from the example shown in FIG.

  The environment data transmission unit 50 transmits the environment data generated by the environment data generation unit 30 to the network. Here, the network may be a wired network or a wireless network. For example, Ethernet (registered trademark) communication may be used as the wired network. As the wireless network, WiFi or a mobile phone network can be used. In the environment measurement system of the present invention, the environment sensor is used in a room, for example, and may move between rooms, so it is preferable to use a wireless network. In addition, when there are a plurality of devices having environmental sensors, it is possible to organize and grasp the environmental data for each device.

  The data storage unit 60 receives and stores the environmental data transmitted from the environmental data transmission unit 50 via the network. The data storage unit 60 is, for example, a server connected to a network, and environmental data for each device may be accumulated in the storage area of the server. In addition, the present invention can be applied to environmental sensors placed as so-called monitoring posts in a plurality of locations, and environmental data in a plurality of locations can be centrally managed in real time.

  Next, in the environment measurement system of the present invention, a configuration that enables position assurance more accurately will be described. FIG. 3 is a schematic configuration diagram for explaining an example in which the environment measurement system of the present invention has a position assurance function. In the figure, the same reference numerals as those in FIG. 1 and FIG. In the example shown in FIG. 3, as in the example described in FIG. 2, the configuration in which environmental data can be transmitted / received via the network is shown, but the present invention is not limited to this, and is shown in FIG. 1. Of course, it is also possible to use a device that does not transmit environmental data, as in the example. As shown in the figure, in this example, an RFID transmitter 41 and an RFID receiver 21 are added from the example shown in FIG. That is, this example is configured to use RFID (Radio Frequency IDentification), which has a shorter transfer distance than the indoor position information transmission / reception unit, to perform measurement using this signal as a trigger. As a result, the measurement area for environmental information is intended to be limited to the area near the RFID transmitter 41. In the following description, the short-range wireless signal transmission / reception system will be described with a focus on RFID. However, as long as the transfer distance is shorter than the position information transmitted from the indoor position information transmitter 40, the RFID is limited to the RFID. It is possible to use various methods such as Bluetooth (registered trademark) and ZigBee (registered trademark).

  The RFID transmitter 41 transmits a radio signal having a transfer distance shorter than the position information transmitted from the indoor position information transmitter 40. That is, the RFID transmitter 41 transmits a radio signal that cannot be received unless it is located in the vicinity of the RFID transmitter 41. Therefore, the RFID transmitter 41 only needs to be arranged in the vicinity of the position to be measured. In the illustrated example, the RFID transmission unit 41 is disposed in the vicinity of the indoor position information transmission unit 40 on the ceiling. However, if the position to be measured is, for example, a corner of a room, the RFID transmission unit 41 may be disposed in the vicinity thereof.

  The RFID receiving unit 21 is disposed in the vicinity of the environmental sensor 20 and receives a radio signal transmitted from the RFID transmitting unit 41. That is, the RFID receiver 21 and the RFID transmitter 41 are for transmitting and receiving a predetermined RFID signal. In order to limit the measurement area, the RFID receiver 21 is arranged in the vicinity of the environmental sensor 20.

  The RFID transmitter 41 and the RFID receiver 21 are used so as to limit the area around the position based on the position information received by the position information receiver 10 within the RFID transfer distance. That is, the environment sensor 20 is configured to measure the environment information in response to the radio signal transmitted from the RFID transmitter 41 being received by the RFID receiver 21. As a result, environmental information can be measured only in the area near the RFID transmitter 41. In other words, it is possible to make it impossible to measure environmental information in an area outside the transfer distance away from the RFID transmitter 41. Further, an RFID radio signal may be used as a trigger for an environmental data generation unit or an environmental data transmission unit, instead of being used as a trigger for starting measurement. Thus, since the measurement position is limited within the RFID transfer distance, the position can be more accurately guaranteed. In addition, since the measurement area can be narrowed, it is possible to prevent impersonation such as changing the measurement position and intentionally making the measurement value appear low.

  Since the environmental measurement system of the present invention can measure environmental data including highly accurate location information even indoors as described above, for example, when evaluating the value of real estate such as an apartment, each room is made of asbestos or radioactive material. It is also possible to measure the environmental information such as whether or not it is contaminated and to confirm safety.

  It should be noted that the environment measurement system of the present invention is not limited to the illustrated examples described above, and it is needless to say that various changes can be made without departing from the scope of the present invention.

Moreover, since environmental information can be obtained via a network as described above, environmental data at a plurality of locations can be grasped in real time.
