Abstract

PURPOSE:To evade crosstalk due to intermission of transmission by providing a controller sending a remote control signal controlling changeover a transmission/reception changeover switch of other transmission/reception device to the sending side and switching the own transmission/reception changeover switch into the reception side when the state is transmitted from the transmis sion state to the reception state. CONSTITUTION:When the own transmission/reception device 1 is transited from the transmission state to the reception state by a controller CT, a remote control signal controlling switchingly the transmission/reception changeover switch SW of the other transmission/reception device 2 to the sending side is sent and then the own transmission/reception changeover switch SW is changed over to the reception side. Thus, even when the transition of the transmission exists between the transmission/reception devices 1 and 2 during correspondence, no transmission of a carrier is intermitted. Thus, crosstalk is prevented.

The present invention provides a simplex type transmitting/receiving device having an antenna, a transmitter, a receiver, and a transmitting/receiving switch that switches and connects the antenna to the transmitter and the receiver, when the transmitting state changes to the receiving state. By providing a controller that transmits a remote control signal that switches the transmission/reception switch of another transmitting/receiving device to the transmitting side, and then switches its own transmitting/receiving switch to the receiving side, the communication between the transmitting/receiving devices during communication can be controlled. Interference due to carrier wave transmission interruption during transmission transition can be avoided.

In a simplex type transmitting/receiving apparatus such as a personal radio type, communication is performed using carrier waves of the same frequency. Communication between such transmitting and receiving devices is performed as follows. It is assumed that the first transmitting/receiving device is in a transmitting state and the second transmitting/receiving device is in a receiving state. At this time, the breath talk switch is turned on in the first transmitting/receiving device, and the breath talk switch is turned off in the second transmitting/receiving device. When the first transmitting/receiving device finishes transmitting a speech, the breathtalk switch is turned off. In this way, the second transmitting/receiving device performs transmission with the Breast Inch turned on. Thereafter, this operation is repeated to perform communication between the first transmitting/receiving device and the second transmitting/receiving device.

Therefore, there is some time between when the breath talk switch of the first transmitter/receiver is turned off and when the breath talk switch of the second transmitter/receiver is turned on. This means that the carrier wave is not being transmitted. Therefore, the third transmitting/receiving device detects whether or not a carrier wave is being transmitted, and if the carrier wave is not being transmitted on that channel, it starts transmitting, causing interference.

Claim 1 of the above claims provides a simplex type transmitting/receiving device having an antenna, a transmitter, a receiver, and a transmitting/receiving changeover switch for selectively connecting the antenna to the transmitter and the receiver. When the transmitting/receiving switch of another transmitting/receiving device changes to the receiving state and a remote control signal is sent to control the transmitting/receiving switch, the controller switches the transmitting/receiving switch of the other transmitting/receiving device to the receiving side. A simplex type transmitting/receiving device characterized by: 2. When the L controller receives the remote control signal from another transmitting/receiving device, it shifts from the listening state to the transmitting state within a predetermined time L7, and if not, transmits the remote control signal. At the same time, the transmitting/receiving device of the simplex method described in Patent No. 1 is characterized in that the transmitting/receiving switch of the transmitting/receiving switch is then switched to the receiving side.

[Scope of Claims] 1. In a simplex type transmitting/receiving device having an antenna, a transmitter, a receiver, and a transmitting/receiving changeover switch for selectively connecting the antenna to the transmitter and the receiver, the transmission state is: A controller is provided that transmits a remote control signal to switch the transmitting/receiving switch of another transmitting/receiving device to the transmitting side when the transmitting/receiving device shifts to a receiving state, and then switches its own transmitting/receiving switch to the receiving side. A simplex type transmitting/receiving device characterized by: 2. When the controller receives the remote control signal from another transmitting/receiving device, if it does not shift from the receiving state to the transmitting state within a predetermined time, the controller transmits the remote control signal and then 2. The simplex type transmitting/receiving device according to claim 1, wherein the transmitting/receiving switch is switched to a receiving side.
