Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As can be seen in Figure 2 composite communication device according to an embodiment of the present invention, the power supply unit 10, the facsimile control unit 20, the facsimile transmission and reception drive unit 30, trunk line interface unit 40, ring detection unit 50 ), A call unit 60, a wired / wireless control unit 70, a wireless unit 80, and a Hart interface unit 90.

The power supply unit 10 supplies the operating power to the facsimile control unit 20 and the facsimile transmission / reception driver 30 in order to convert the commercial AC power on the SMPS into a predetermined state and execute only the facsimile function.

The facsimile control unit 20 is composed of a CPU, a memory, and a modem in the same configuration as the conventional system described above, and controls the overall operation of transmitting and receiving image information.

The fax transmission / reception driver 30 performs an operation for stable transmission and reception of image information according to the control signal of the fax control unit 20.

The trunk line interface unit 40 connects a communication path between the trunk line and the facsimile system to transmit and receive image information.

The ring detector 50 connects the tip of the trunk line through the resistor R and the condenser C. The ring terminal is coupled through the bidirectionally coupled diodes D1 and D2. It consists of a photodiode (PC3) is switched when the ring signal is applied through the detection of the ring signal applied through the trunk line and applies a signal for it to the wired / wireless controller 70 side.

In this case, a power of a separate molded power supply unit is connected to the photodiode PC1.

The communication unit 60 maintains stable voice communication through a wireless channel and a call through a wire when a call path is connected through a trunk line.

The wired / wireless control unit 70 controls the overall operation of the call over the wire or the call over the wireless channel according to the selected mode.

The wireless unit 80 receives power from a separate linear power supply unit and keeps the call stable through the wireless channel.

Halt interface unit 90 is composed of a plurality of photo coupler (PC2) (PC3), in accordance with the signal of the wired / wireless control unit 70 to Halt the fax system when executing a voice call over a wireless channel or wired A switching operation is executed, and the switch is switched according to the Halt request (H / Req) signal applied from the facsimile control unit 20 to output a signal for stably maintaining a voice call through the wireless channel.

As shown in FIG. 3, the linear power supply unit 100 includes a transformer Tr for stepping down the supplied commercial power to a predetermined voltage, a bridge diode BD101 for full-wave rectifying the stepped power, and rectification. The capacitor (CI) for removing the ripple of the old power, and the regulator 100 for maintaining a stable voltage of DC 5V required for the circuit to remove the ripple.

In the present invention having the function as described above, as shown in Figure 4 attached to the operation to secure the communication distance and the stable call to the system as follows.

First of all, operations for connection to a call and transmission and reception of voice and data through a connected call path are the same as operations in a general telephone, and thus will be omitted.

The controller 20 of the facsimile system periodically outputs the HART request signal (H / Req) in a low state while the wired / wireless communication path and the facsimile system are waiting to be transmitted. When applied to the side, the Halt interface unit 90 switches the first photo coupler PC1 according to the applied signal so as to recognize the signal H / Req for the Halt request to the wired / wireless controller 70.

At this time, the wire / wireless control unit 70 outputs a low state signal for switching the second photo coupler PC2 of the halt interface unit 90 to form the facsimile system control unit 20 in a halted state according to an applied signal. In order to enter the facsimile system control unit 20 into the halted state by switching the second photo coupler (PC2).

Therefore, since the operation of the facsimile system control unit 20 is stopped and the operations of the CPU, memory, and modem constituting the facsimile system control unit 20 are stopped, the generation of high frequency is interrupted and the emission of noise is blocked.

As such, when a predetermined time elapses while the operation of the system control unit 20 is stopped, the wire / wireless control unit 70 outputs a high state signal to the second photo coupler PC2 of the halt interface unit 90 to facsimile. The halted state of the system control unit 20 is released.

In this case, when data for a call request is received from the wireless handset, the wired / wireless controller 70 maintains a continuous halt state without releasing the halt state of the facsimile system controller 20 to remove noise emitted from the facsimile system controller 20. By shutting off, the wireless unit 80, which is supplied with a separate linear power source, maintains a stable call continuously without being affected by noise.

Subsequently, when the end of the call is detected, the wired / wireless controller 70 outputs a high signal to the second photo coupler PC2 of the halted interface unit 90 to release the halted state of the facsimile system controller 20, and the operation described above.

When the Halt request signal H / Req is detected, the facsimile system applies a Halt signal in a low state to the second photo coupler PC2 side of the Halt interface unit 90 in the same manner as described above. The control unit 20 maintains the Halt state, and then maintains the Halt state until the termination of the incoming ring applied from the CO line, thereby stably maintaining data communication with the wireless handset.

At this time, when the incoming ring from the trunk line is terminated, the wire / wireless control unit 70 outputs a high state signal to the second photo coupler PC2 of the halt interface unit 90 through the operation as described above, thereby facsimile system control unit 20. Had a state of).

In addition, when data on a call connection is detected in the wireless handset in the reception state of the trunk line ring in which the facsimile system control unit 20 maintains a halt state, the wired / wireless control unit 70 continuously maintains the halt state of the facsimile system control unit 20. And secures a stable call and a communication distance without noise. When the end of the call data is detected from the wireless handset, the wired / wireless control unit 70 moves to the second photo coupler PC2 of the halt interface unit 90 according to the above-described operation. The signal is output to release the halted state of the facsimile system control unit 20.

The operation as described above will be described in more detail with reference to FIG. 4.

In the standby state where power is supplied to each circuit unit, the wire / wireless control unit 70 detects a Halt request signal H / Req that is periodically applied from the facsimile system control unit 20 (S1).

When the Halt request signal H / Req is detected in step S1, a Halt signal in a low state is outputted to switch to a Halt state for stopping the operation of the facsimile system control unit 20 through the Halt interface unit 90. If the halt request signal H / Req is not detected (S7), it is determined whether the current facsimile system control unit 20 maintains a halt state (S2).

In step S2, if the facsimile system control unit 20 maintains the state of the halt, but is detected as data for terminating the halt state after a set period of time, the wired / wireless control unit 70 controls the facsimile through the halt interface unit 90. The halted state of the system control unit 20 is released (S8) (S9).

In addition, it is determined whether an incoming ring signal applied from the trunk line is detected (S3), and when the incoming ring is detected, the wired / wireless control unit 70 sets the facsimile system control unit 20 to the state of Halt through the hart interface unit 90. (S10), detecting whether the call is terminated (S4) (S9).

In step S4 or S9, if the end of the call is detected, the halt of the facsimile system control unit 20 is released, and if a continuous call is detected, the current halt is maintained to secure a stable call and provide a distance.

The operations of halting and releasing of the facsimile system control unit as described above are repeatedly executed at respective conditions and intervals of time set.
