Abstract

An environmental monitoring radiotelemetry system has been developed which is capable of monitoring personnel exposed to severe heat stress conditions in occupational environments. This system enhances advanced multidisciplinary research in the fields of occupational health and industrial hygiene. The monitor detects and transmits information about air temperature, humidity, and heat radiation surrounding workers in industry. Also, physiological parameters such as pulse rate, deep body temperature, and skin temperature are transmitted. The system can easily be adapted to transmit other information such as bioelectric signals, galvanic skin response, blood pressure, etc. The radiotelemetry system utilizes bridge type transducer networks, pulse width modulations, and time division multiplexing. Seven data channels are transmitted on a common radiofrequency carrier selectable on request. Modular design is utilized throughout. The concept of a personal environmental monitoring system has been realized with this system. Applications to industrial hygiene research have successfully generated new information about environmental stress affecting the health of workers within a wide range of occupational environments.
