摘要： A swimming pool drowning prevention safety system. The swimming pool drowning prevention safety system comprises: an article wearable by a person, a radio frequency transmitting device coupled to the article for transmitting a radio frequency signal, a microprocessor controlled radio frequency receiving station for receiving the radio frequency signal from the radio frequency transmitting device when the radio frequency transmitting device is within a user adjustable radio reception range of the radio frequency receiving station, and an alert signaling device coupled to the radio frequency receiving station for signaling when the person wearing the article has come within the user adjustable radio reception range of the radio frequency receiving station. The swimming pool drowning prevention safety system is further comprised of an adjustable gain control for varying the RF sensitivity of the radio frequency receiving station, and an RF sensitivity trigger circuit coupled to an audio messaging system for broadcasting at least one selected alert message. The swimming pool drowning prevention safety system further comprises telephone circuitry connection equipment for automatically connecting to a telephone system and transmitting the selected alert message. The swimming pool drowning prevention safety system further comprises a microprocessor that controls and integrates operation of the radio frequency receiving station.
