One can select whether to collect sensing data from one or more than one particular transponder 11. When collecting detection data from a specific transponder 11, the identification information of the transponder 11 whose data is to be collected is specified.

When the above application starts, the PC
16 monitors whether a data collection instruction has been input (S
A1) When a data collection command is input, the measurement start time is recorded, and it is determined whether the transponder 11 to be collected is all transponders or a specific one (SA2). If the result of this determination is that the transponders 11 to be collected are all transponders, a data collection interval time and an instruction signal transmission command to all the transponders 11 are output to the scanner 14 (SA3). If the transponder 11 to be collected is a specific transponder, the scanner 14 outputs an interrogation signal transmission command to the transponder 11 having the data collection interval time and the specified identification information (SA4). .

The scanner 14 monitors whether or not a data collection command has been input from the PC 16 (SB1). When the data collection command has been input, the transponder 11 to be collected is all transponders. It is determined whether it is a specific one (SB2). As a result of this determination, when the transponders 11 whose data is to be collected are all transponders, all the transponders 1
1 is transmitted to SB1 (SB3).

When 14 prototypes are produced, it is easy to examine the heat dissipation, heat retention, sweat dissipation, and the like. Furthermore, since the detection data can be collected wirelessly, it is easy to collect the detection data even when the player exercises.

In addition, since it is possible to easily identify a detection location corresponding to each of a plurality of pieces of detection data by identification information unique to each transponder, it is possible to perform measurement at many locations even using only one communication channel.

Further, since the transponder 11 is not directly attached to the skin of the human body but attached to the wears 13a and 13b, the sensors 35 and 36 of the transponder 11 do not directly touch the human skin. Temperature and humidity in the surrounding atmosphere of the human body can be detected.

In the above embodiment, the measurement system suitable for the development of the wear is configured, but it goes without saying that the present measurement system is not intended only for the development of the wear. For example, in the present embodiment, the transponder 11 including the temperature sensor and the humidity sensor is configured, but it goes without saying that a transponder including other types of sensors such as a pressure sensor and an illuminance sensor may be configured.

In this embodiment, the transponder 11
Is operated by electromagnetic wave energy in order to reduce the weight of the scanner, but a transponder operated by a button-type battery may be configured to extend the communication distance with the scanner 14.

The transponder 11 and the scanner 14
A communication medium other than electromagnetic waves such as ultrasonic waves and light may be used as a communication medium between them.

In this embodiment, a system for measuring a physical quantity in the surrounding atmosphere of a human body is configured. However, a system for measuring a physical quantity in the surrounding atmosphere of a human body other than the human body may be configured. This object may be a non-human creature or a non-living creature.

Further, in this embodiment, the wears 13a and 13b are used as the separating means, but the present invention is not limited to this.

Further, the configurations of the measuring system and each device in the present embodiment are merely examples, and the present invention is not limited to the configuration of the above embodiment.

Physical quantities can be measured wirelessly. This eliminates the need to increase the number of interfaces corresponding to the number of sensors unlike the conventional example, so that the apparatus can be formed in a small size and the cost can be reduced. Therefore, the number of sensors can be easily increased as needed.

Further, even when a sensor is attached to a living thing such as a human to measure a physical quantity such as temperature and humidity, the conductive wire as in the conventional example does not interfere. Therefore, measurement of physical quantities such as temperature and humidity around the human body during exercise can be performed very easily.
