Next, the operation of the face-to-face active communication device of the present invention will be described.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the user can continuously press the reset switch for more than 3 seconds to enable the active communication device. After the active communication device is enabled, the task manager 1 will be according to FIG. 3 . Program running: In step 301, the task manager 1 reads the device setting information in the flash memory 7 via the memory-infrared processor 3, and in step 302, determines whether the device function is normal according to the device setting information. . If the function of the device is not normal, step 303 is executed, and the task manager 1 drives the red indicator light 142 to blink 3 times to remind the user, and then the task manager 1 ends the program.

If the function of the device is normal, step 304 is executed, and the task manager 1 drives the green indicator light 141 to blink three times to remind the user that the device functions normally. Then, step 305 is continued, and the task manager 1 enables the infrared-memory processor 2 to enter the file receiving mode. Then, in step 306, the task manager 1 determines whether the file receiving mode is interrupted, that is, whether to receive an external interrupt request from the computer to manage the content of the flash memory 7, or from the reset switch 13 once. Press the triggered interrupt request to force entry into the file transfer mode. If no interruption occurs, the task manager 1 continues to perform step 307 to determine whether it has entered the file receiving mode for more than 60 seconds, or has successfully received the file, if the file receiving mode has been exceeded for 60 seconds or the file has been successfully received. Then, in step 308, the task manager 1 enables the memory-infrared processor 3 to enter the file transfer mode. After completion, the task manager 1 switches again to perform step 305, that is, switches the file receiving mode again. formula. In other words, the task manager 1 will actively switch execution between the file receiving mode and the file transfer mode. The procedure of the file receiving mode of the above step 305 and the file transfer mode of step 308 will be described with reference to Figs. 5 and 4, respectively.

If the task manager 1 determines in step 306 that the file receiving mode is interrupted, step 309 is performed. In step 309, if the interrupt request is from a request to enforce the file transfer mode, step 308 is performed. If the interrupt request is generated from the computer, instead of requesting execution of the file transfer mode, step 310 is performed. After receiving the file in progress, the task manager 1 enables the computer-memory processor 8 and the memory-computer processor 9 to communicate with the universal serial bus/universal asynchronous transceiver interface IC 10 The computer performs communication and data transmission. Then, in step 311, the task manager 1 determines whether the communication with the computer has ended. If not, the process continues to step 310. If it is over, the process returns to step 301. Start the execution of the task manager 1.

5 shows a procedure in which the task manager 1 executes the file receiving mode: First, in step 501, the task manager 1 requests the infrared-memory processor 2 to listen to the "hello code frame" via the infrared receiver 4. Next, step 502 illustrates that if the infrared-memory processor 2 does not receive the "hello code frame" during 60 seconds, step 503 is executed, and the task manager 1 terminates the infrared-memory processor 2 Monitor and end the file receiving mode.

On the other hand, if the infrared-memory processor 2 receives the "hello code frame" during 60 seconds, the process proceeds to step 504, and the infrared-memory processor 2 will use the device according to the "hello code frame". The identification code is used to determine whether the same device identification code is received three times in succession. If yes, it means that the file of the same active communication device has been received multiple times, so in step 505, the infrared-memory processor 2 reports the task management. The person 1 repeats the reception and returns to step 501.

If the infrared-memory processor 2 determines in step 504 that the device identification code of the "hello code frame" received is not continuously repeated three times, step 506 is performed. In step 506, the infrared-memory processor 2 reports the task management The "Hello Code Frame" has been received, and then, in step 507, the task manager 1 requests the memory-infrared processor 3 to transmit the "weight box" via the infrared emitter 5. In step 508, the memory-infrared processor 3 reports that the task manager 1 has sent the "weight box". In step 509, the task manager 1 requests the infrared-memory processor 2 to prepare to receive the file transmitted from another active communication device via the infrared receiver 4.

In step 510, the infrared-memory processor 2 determines whether the file composed of the "data frame" is received during 2 seconds. If the file is not received within 2 seconds, step 511 is executed, the infrared- The memory handler 2 reports that the task manager 1 file reception failed, and then returns to step 501. If the infrared-memory processor 2 receives the file during 2 seconds, then following step 512, the infrared-memory processor 2 reports that the task manager 1 has received the file and passes the received file via the file. The memory manager 6 writes the flash memory 7, and then performs step 513, the task manager 1 lights the green indicator light 141 for 0.5 seconds to indicate that the file has been successfully received from another active communication device, and The task manager 1 ends the program of the file receiving mode.

When the task manager 1 switches to execute the file transfer mode, the program is as shown in FIG. 4. In step 401, the task manager 1 requests the infrared-memory processor 2 to monitor the channel signal via the infrared receiver 4. Next, in step 402, if the infrared-memory processor 2 receives the signal via the infrared receiver 4 during 50 microseconds, then step 403 is performed, wait 2 seconds, and then return to step 402 again until the transmission is determined. The channel is in a clear state, and then proceeds to step 404, that is, the infrared-memory processor 2 reports that the task manager 1 channel has cleared.

In step 405 and step 406, the task manager 1 first requests the memory-infrared processor 3 to send the "hello code frame" via the infrared emitter 5, and after completion, the memory-infrared processor 3 reports the Task Manager 1 "Hello Code Frame" has been sent. Next, in step 407, the task manager 1 requests the infrared-memory processor 2 to receive the "code frame" sent from another active communication device via the infrared receiver 4. In step 408, if If the infrared-memory processor 2 does not receive the "weight box" within 4 microseconds, step 409 is executed, and the infrared-memory processor 2 reports that the task manager 1 has not received the "weight box". At the same time, the task manager 1 ends the file transfer mode.

Conversely, in step 408, if the infrared-memory processor 2 receives the "weight box" within 4 microseconds, then proceeds to step 410. In step 410, the infrared-memory processor 2 reports that the task manager 1 has received the "weight box". In step 411, the task manager 1 requests the memory-infrared processor 3 to transmit my file, that is, the pre-recorded file. In step 412, the memory-infrared processor 3 informs the memory manager 6 to read the pre-recorded file of the flash memory 7. In step 413, the memory-infrared processor 3 transmits the file via the infrared emitter 5 in a "data frame". In step 414, the memory-infrared processor 3 reports that the task manager 1 has sent the file. In step 415, the task manager 1 drives the green indicator light 141 to emit light for 0.5 seconds to remind the user that the pre-recorded file has been transferred and ends the program of the file transfer mode.

In addition, in step 402 of FIG. 4, 50 microseconds is obtained by experiencing a "data frame" period of 100 bits by the 2 Mbps infrared transceiver 17; in addition, at step 408, 4 microseconds represents 1 Waiting time for each byte. Here is an example of why a 256KB file can be transferred in 1.5 seconds: first select 2Mbps infrared transceiver 17, and the data frame is separated by 4 bits, so the file transfer time is 500 (ns) /bit)×100(bit/cycle)×(2M/80)(cycle)=1.31072s, in other words, two-way file transfer can be completed within 3 seconds of two active communication devices face-to-face, thus achieving face-to-face initiative The unique function of the communication device: "Meet the instant and realize the exchange of ideas".

As shown in FIG. 6, the portable power supply 12 includes a rechargeable battery, a step-down IC, a general-purpose serial bus (USB) voltage to charge the battery, and a boost IC, as in the design of a general mobile communication. The voltage of the battery is raised to the voltage level required for powering the device, and the controller IC 16 low battery alarm can be provided in time to facilitate the controller IC 16 to flash the red indicator 142 and shut down.

The face-to-face active communication device of the present invention has a USB port connected to the computer; the user can manage the content of the flash memory 7 through the graphical user interface 11 of the computer platform, and the management manner thereof includes: “System Information” of FIG. 8 The query, the "import file" of Fig. 9, the "read file" of Fig. 10, the "export file" of Fig. 11, the "clear data" of Fig. 12, and the "close" interface function of Fig. 13.

In commercial situations, the broadcast function can bring multiple business opportunities. Since the status information of the "hello code frame" has a broadcast function that can be enabled, when the infrared-memory processor 2 receives the infrared receiver 4 When the "hello code frame" of the broadcast function is enabled, the task manager 1 in the file receiving mode requests the memory-infrared processor 3 not to transmit the "weight box", and the infrared light is required - The memory processor 2 receives the file composed of the "data frame" via the infrared receiver 4.

In summary, the face-to-face active communication device of the present invention provides a user to pre-store the file to be publicly shared in the flash memory 7 and wear the active communication device on the body, and walk in the crowd once When the active communication device is face-to-face with the active communication device worn by another person, the "hello code frame" and the "weight frame" can be automatically connected with the other active communication device to exchange and share. Each of the pre-recorded files, and the two active communication devices face-to-face to complete the file exchange sharing process in less than 3 seconds, so that the active communication devices can be quickly shared by the face-to-face, and These wearers do not need to conduct any conversations, and do not need additional operations to pair the active communication devices, so that they can actively realize "meeting moments, realize the exchange of ideas" in daily life, and create commercials through the broadcast function. Trading opportunities, so the potential for helping the community develop cannot be ignored. Therefore, the object of the present invention can be achieved.
