PROBLEM TO BE SOLVED: To enable a worker to recognize an object to electronically and automatically perform specification of constituting elements of the object and authentication of equipments. SOLUTION: A modulated infrared signal including visible light from a laser pointer is received by a light reception part 11, and a demodulation part 12 demodulates this signal and sends it to a control means 30. This means 30 analyzes the demodulated signal and sends information of the discrimination ID, position coordinates, the equipment attribute, etc., corresponding to this signal to a modulation part 22 of a return means 20. The modulation part 22 superposes sent information on the high frequency carrier of an oscillation part 21 to send it to a transmission antenna 23, and it is transmitted as a high frequency radio wave. A wireless base station receives this high frequency radio wave to automatically perform recognition of the object, data analysis, etc. |
