Therefore, in the system according to the present invention, not only voice communication through the microphone is possible, but also mass data communication through a data transmission device is possible.

5 is a flowchart schematically illustrating a process of transmitting and receiving large data in a large data wireless transmitting and receiving system according to an embodiment of the present invention.

As shown in FIG. 5, first, the controller of the wireless connection unit is initialized (S51).

For example, the RAM, the head and the address of the various components of the controller are initialized and the master Bluetooth of the wireless connection unit and the slave Bluetooth of the data transmission device are connected (ACL or SCO).

In addition, the transceiver performs initialization of the transceiver, which sets the data transfer rate in the range of data transfer rate, 75, 150, 300, 600, 1200, 2400, 4800, 16000bps (S52).

In this case, when the large-capacity data transmission between the transceiver and the wireless connection unit is a digital conversion of the analog data, the serial transmission (SERIAL TRANSMISSION) method, and follows the synchronous transmission (Synchronous communication) to be compatible with the existing radio.

Subsequently, a reception mode or a transmission mode switching process for transmitting and receiving data from the data transmission device is performed.

That is, if the control unit of the wireless connection unit determines whether the reception mode (S53), if the reception mode, the control unit converts the transceiver to the reception mode / data mode to allow the transceiver to receive data from the other transceiver and this BT reception data buffer Store in

Thereafter, the data stored in the BT reception data buffer is received by the data transmission device through the master Bluetooth (S54).

However, the control unit determines whether the transmission mode is not the reception mode (S55), and if the transmission mode, the control unit stores the data received from the data transmission device in the BT reception data buffer.

Thereafter, the control unit converts the transmission / reception unit into a transmission mode / data mode so that the transmission / reception unit transmits the stored data to the transmission / reception unit of the other system (S56).

In addition, the BT reception data buffer may play a role in the EEPROM of the wireless connection unit.

As shown in FIG. 6, all devices of the large-capacity data wireless transmission / reception system according to an embodiment of the present invention are powered on, and the controller of the wireless connection unit attempts to transmit slave Bluetooth around the master Bluetooth. Investigate the data transmission device to check the connection between the master Bluetooth of the wireless connection unit and the slave Bluetooth of the data transmission device and ACL or SCO (S61).

When connected to the slave Bluetooth, the controller of the wireless connection unit checks whether there is data received from the slave Bluetooth (S62), otherwise continues to try to connect to the slave Bluetooth.

In addition, if there is data received from the slave Bluetooth, the controller stores the received data in the BT data receiving buffer and prepares to transmit data to the transceiver (S63).

Subsequently, for communication between the control unit and the transceiver unit of the wireless connection unit, the controller converts the transceiver unit into a data transmission mode and initializes the transceiver unit, where the transmission unit determines the transmission speed and connects the E pin of the transceiver interface to GND. The transmitter / receiver performs digital data mode (data transmission mode) conversion (S64).

Thereafter, the controller connects the C pin of the transceiver interface to GND to check whether the PTT switch is on or off (S65), and when the PTT switch is on, a clock is generated from the transceiver to the D pin of the interface within 40 msec from PTT on (input) (S66). Otherwise it will continue to check whether the PTT switch is on.

Subsequently, when there is a clock input from the transceiver, the controller transmits the data stored in the BT data receiving buffer to the transceiver in accordance with the clock generation of the transceiver, and the transceiver outputs the stored data and transmits it to the transceiver of the other system ( S67).

At this time, the control unit does not immediately transmit data in accordance with the clock generation, as follows, because the time required for about 2 msec due to the internal hardware setup time of the transceiver.

Therefore, the controller waits for 2 msec from the clock generation and then sends data or sends dummy data (AA, etc.) to the F pin of the transceiver interface for 2 msec from the clock generation.

In addition, such data is transmitted until there is no data received from the slave Bluetooth. That is, the controller checks whether there is remaining data without transmitting to the BT data receiving buffer (S68), and if there is remaining data that has not been transmitted, repeats the steps S66 to S67 until the transmission of the remaining data is completed. do.

However, if all data transmission is completed, the controller checks whether the PTT switch of the transceiver unit is turned off (S69), and when the PTT switch is turned off, the process of transmitting a large amount of data is terminated. Otherwise, the PTT switch is continuously turned off. Repeat the process.

 Meanwhile, the reception process of the transmitted large data signal will be described with reference to FIG. 7.

The controller of the wireless connection unit examines the slave Bluetooth connected to the master Bluetooth, that is, the data transmission device to be received, and checks whether the master Bluetooth of the wireless connection unit and the slave Bluetooth of the receiving data transmission device are connected to the ACL or SCO (S71). .

When connected to the slave Bluetooth, the controller converts the transceiver into a data reception mode and initializes the transceiver, where the transceiver determines the data transmission rate and connects the E pin of the transceiver interface to GND to connect the transceiver to the digital data mode (data). Reception mode) conversion is performed (S72). Otherwise, it will continue to attempt to connect with the slave Bluetooth.

Thereafter, the controller connects the C pin of the transceiver interface to GND to check whether the PTT switch is turned off (S73). If the PTT is switched off, the transceiver receives data and generates a clock from the transceiver to the D pin of the interface. Input) is checked (S74). Otherwise, it will continue to check whether the PTT switch is on or clock input.

Thereafter, if there is a clock input from the transceiver, the controller stores the data received through the transceiver interface B pin in accordance with the generated clock in the BT data reception buffer of the radio connection unit (S75).

Thereafter, such a large data is received until the preamble signal, which is a data end signal, is received and stored in the BT data receiving buffer. That is, the controller checks whether the received data signal is a preamble signal (S68).

Here, if it is a preamble signal, the data stored in the BT data receiving buffer is transmitted to the slave Bluetooth of the data transmission device. Otherwise, the data receiving process from the transmitter to the wireless connection unit until the data reception end signal, that is, the preamble signal, is S74 to S75. By repeating the steps of the large data reception process is terminated.

Here, the BT received data buffer may play a role in the EEPROM of the wireless connection unit.
