Abstract
A simultaneous transmitting/receiving distance alarm consisted of one or more transmitter set and one receiver set, in which: a transmitter set comprises a pulse control circuit, a quartz crystal, a transmitting circuit and an antenna; a receiver set comprises an antenna, a receiving circuit, a control circuit, a quartz crystal, a receiving circuit switch control and a sounding body or a vibration body; which is characterized in using the transmitter set to send out a simple pulse signal at a fixed interval such that a receiver set capable of automatically aligning with the pulse sequence of the transmitter set can simultaneously cut off its receiving circuit when the transmitter stops transmitting within the time interval, and reopen its receiving circuit before the expected start of the generation of the next transmission pulse in order to receive the signal of the transmitter set; in which, when the transmitted pulse signals are not received for once or a continuous number of times, the wearer of the alarm will be notified by sound or vibration thereby achieving warning the operator.
