- the infrared phototransistor of the infrared transmitter / receiver TRIR1 of the name tag type sensor terminal TR2 is configured such that the infrared transmitter / receiver TRIR1 to TRIR6 of the name tag type sensor terminal TR1 transmits infrared data at least once. During transmission, it is ready to receive.
- the infrared phototransistors of the infrared transceivers TRIR2 to TRIR6 of the name tag type sensor terminal TR2 are controlled so that they can be received in a time division manner.
- the power consumption of the infrared phototransistors of the infrared transceivers TRIR1 to TRIR6 is normally reduced by setting the infrared phototransistors of the infrared transceivers TRIR1 to TRIR6 of the name tag type sensor terminal TR to be in a time-receivable state. Can be reduced to 1/6 or less.
- the name tag type sensor terminal TR In order for the name tag type sensor terminal TR to be able to receive the infrared phototransistors of the infrared transmission / reception units TRIR1 to TRIR6 in a time-sharing manner, the name tag type sensor terminal TR transmits and receives all infrared signals of the other name tag type sensor terminals TR. Although it is necessary to grasp the time for which the infrared light emitting diodes of the units TRIR1 to TRIR6 transmit infrared data once, as described above, since each name tag type sensor terminal TR synchronizes its operation, other name tag type sensor terminals TR Can grasp the transmission time of infrared data.
- the infrared phototransistors of the infrared transceivers TRIR5 and TRIR6 arranged on the left side and the right side of the name tag type sensor terminal TR are connected to the infrared transceivers TRIR1 to TRIR4 arranged in front of the other name tag type sensor terminal TR.
- Infrared data can be prevented from being received by the infrared light emitting diode. That is, the name tag type sensor terminal TR can prevent erroneous detection of the face-to-face contact between the wearer and the wearer positioned in the lateral direction of the wearer and simply facing the wearer.
- the name tag type sensor terminal TR is a microcomputer MCU of the name tag type sensor terminal while not sending and receiving infrared data. May be switched to a low power consumption state in which the power consumption is lower than in the normal state. Thereby, the power consumption of the name tag type sensor terminal TR can be reduced.
- the plurality of optical transmission / reception units are arranged so that the optical axes of the plurality of optical transmission / reception units approach toward the outer side of the casing.
- the wiring can be made shorter than when the main board and the optical transmission / reception unit are connected by wire. It is possible to reduce noise to various sensors when light is emitted.
- the present invention can be applied to a sensor terminal that uses optical communication to detect a wearer's face-to-face.
