Equipped with.

The display unit 16 is configured to display the transmission / reception data and, in addition, to briefly display the operating state of the device such as whether or not the power is turned on and whether it is operating in the wireless service area. The voice synthesizing unit 17 is also configured to output the output mode, various alarms, and the like by voice in addition to the received data.

The sun visor 12 is further provided with a power source / volume switch 20, an antenna 19 and a light emitting diode 21.

When the on-vehicle data communication device 11 is used in an area where the radio wave is weak, an antenna mounted outside the vehicle may be used instead of the antenna 19.

As shown in FIG. 2A, the operation keys 14,
The display 16 and the speaker 18 are the sun visor 12
(Hereinafter, the surface facing upward when the sun visor 12 is housed on the roof side is referred to as the back surface and the surface facing downward is referred to as the front surface).

The transmitting / receiving unit 13, the control unit 15 and the voice synthesizing unit 17 are also preferably attached to the sun visor 12 in the same manner. May be reduced.

The speaker 18 may be provided at any position where the driver can hear it, and may be attached to the driving seat, for example.

As described above, the operation key 14 can input transmission data, and can also select and set an output mode, that is, an output timing and an output type.

FIG. 3 shows the details of the control unit 15.

As can be seen from FIG. 3, the control unit 15 has a data storage unit 22 for storing the transmission / reception data.

Further, the control unit 15 loads the reception data accumulated in the data accumulating unit 22 according to the above-mentioned output mode at the time of reception, and determines whether the loaded reception data is voice data or not. Operation key 1 when sending
The data storage unit 22 that converts the input data input in 4
The data processing unit 23 for sending to

Further, the control section 15 is provided with a voice data creating section 24 which creates voice data from received data which is not voice data, and a database 25 which stores data for creating voice data.

Next, the procedure for receiving data using this embodiment will be described.

First, before starting data reception, the output mode is selected and the output timing and output type are set. At the time of setting, the operation key 14 is operated with the sun visor 12 in a downwardly expanded state.

This operation can be performed even while driving, with almost no deviation of the line of sight from the front.

If the output time is set to, for example, a mode in which the data is received and the received data is output at the same time,
The received data is stored in the data storage unit 22 and then immediately sent to the data processing unit 23.

If the temporarily stored reception data is set to a mode in which it is output every set time, when the set time is, for example, 10 minutes, the received data is sequentially stored in the data storage unit 22 for 10 minutes. The received data that has been stored after 10 minutes has passed is sent together to the data processing unit 23.

If a mode is set in which the received data stored when the output switch (not shown) is operated is set, the received data is sequentially stored in the data storage unit 22, and the output switch is turned on. When activated, the received data stored so far is sent to the data processing unit 23.

In this case, it is preferable that the light emitting diode 21 or a buzzer (not shown) be used to inform the driver that the data has been received.

Further, if the mode is set so that the received data is output only when the sender requests a response,
Received data is sequentially stored in the data storage unit 22,
The data processing unit 23 only when the response request data is received.
Sent to.

Regarding the output type, if this is set to a mode in which only the data from a specific business office is output, the received data will be sequentially stored in the data storage unit 22, and the above-mentioned specific data will be stored. Is sent to the data processing unit 23 only when is received.

After the output mode is set in this way, the sun visor 12 is set in an unused state, that is, in a state of being housed above, and waits for the reception of data.

Such an output mode can be set at any time by expanding the sun visor 12 while waiting for data reception.

Further, in the waiting state for reception, the transmission mode can be switched at any time.

The flow after receiving the data is shown in the flowchart of FIG.

Depending on the above-mentioned output timing and output type,
When the received data is sent from the transmission / reception unit 13 to the data processing unit 23 via the data storage unit 22, the data processing unit 23 determines whether the received data is numerical data consisting only of numerical values or kanji and kana mixed. Determine if it is voice data.

If the received data is voice data,
The received data is sent to the voice synthesizer 17.

If the received data is numerical data,
The received data is sent to the voice data creation unit 24.

The case where the numerical data is either inventory data or price data will be described below as an example.

The voice data creation unit 24 determines whether the received data sent is inventory data or price data.

If the received data is inventory data, the type and number of products are read from the received data.

Next, the kanji kana magic data is read from the database 25, and the kanji kana magic data is combined with the numerical data of the type and the number described above to create voice data.

If the received data is price data, the type of product, the size of the lot, and the price are read from the received data.

Then, voice data is created in the same manner as the case of inventory data.

The voice data thus created is sent to the voice synthesizing section 17, which synthesizes a voice signal from the voice data and sends it to the speaker 18.

The speaker 18 outputs the voice signal as voice.

As described above, since the received data is output as a voice, the driver can check the contents of the received data while keeping his or her line of sight forward.

It is also possible to send the received data from the data processing section 23 to the display unit 16 and display the received data on the display unit 16.

Even in this case, the driver can confirm the received data displayed on the display 16 without greatly removing the line of sight directed forward.

Next, the procedure for transmitting data will be described.

When transmitting data, the driver expands the sun visor 12 and inputs the data with the operation keys 14.

In this case, if the data does not have to be transmitted immediately, the data can be transmitted safely when the vehicle is stopped.

Further, even when data transmission is inevitable during driving, the input operation can be performed with the line of sight hardly deviated from the front.

The input data is sent to the data processing section 23.

The data processing unit 23 converts the input data into a transmittable format and sends the converted data to the data storage unit 22.

The data storage unit 22 sends the transmission data to the transmission / reception unit 13, and the transmission / reception unit 13 transmits the transmission data to the antenna 1
Send at 9.

The vehicle-mounted data communication device 1 according to the present embodiment.
Two may be used together, one dedicated to data communication and the other conventional MCA radio 1 dedicated to voice communication.

In this embodiment, the on-vehicle data communication device 11 is used.
Is mounted on the back surface of the sun visor 12 of the automobile, the on-vehicle data communication device of the present invention can confirm the received data by hearing. May mount a speaker, a light emitting diode, or the like on the surface of the sun visor, and the entire on-vehicle data communication device of the present invention may be a conventional MC.
