Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone and a data transmission method using the same.

[0002]

2. Description of the Related Art Generally, in the case where there is a wired telephone facility, a MODEM can be connected to the telephone line to transmit the data of the field equipment collected by a personal computer or the like.
However, in the field such as outdoors where there is no wired telephone facility, the MODEM cannot be connected with the conventional mobile phone. Therefore, it is necessary to store the data in a floppy disk or the like, bring it back to the maintenance base where the wired telephone facility is located, and transmit the data using the telephone line of this maintenance base.

[0003]

The data of field equipment collected by a personal computer or the like often needs to be transmitted to the manufacturer's factory or the like as soon as possible. However, in the field where there is no wired telephone equipment, as described above, data cannot be directly transmitted, so it is necessary to return to a maintenance base where the wired telephone equipment can be used, and traffic time during that time is required.

Therefore, the present invention enables data to be directly transmitted from a site without wired telephone facilities.
The purpose is to omit the time required for other than the original data transmission.

[0005]

According to a first aspect of the present invention, there is provided a mobile phone having a modular terminal or a serial terminal for connecting to a data transmitting device for outputting a signal, and a receiver unit for inputting and outputting voice. A switching unit that selects either one of the signal from the modular terminal or the serial terminal and the signal from the handset unit, and a wireless telephone unit that converts the signal from the switching unit into a wireless signal and outputs it to the telephone network. Prepare In the data transmission method of the invention of claim 2, the modular terminal or serial terminal of the mobile phone according to claim 1 is connected to the data transmission device that outputs a signal, and the signal from the data transmission device is switched by the switching part of the mobile phone. Is selected, the signal is converted into a wireless signal by the wireless telephone unit of the mobile phone, output to the telephone network, and the signal is transmitted to the data receiving device connected to this telephone network.

[0006]

In the mobile phone according to the present invention, the signal output from the data transmitting device is received at the modular terminal or the serial terminal, the voice is input and output at the handset section, and the signal is output from the modular terminal or the serial terminal at the switching section. One of the signal and the signal from the handset unit is selected and output to the wireless telephone unit. The wireless telephone unit converts this signal into a wireless signal and outputs it to the telephone network.

In the data transmission method according to the second aspect of the present invention, the collected data is directly transmitted from the data transmission device to the data reception device via the telephone network from the data transmission device at the site where there is no wired telephone facility. Therefore, it is possible to omit a time such as traffic time which is not necessary for the original data transmission.

[0008]

FIG. 1 shows an embodiment of the present invention. The data transmitter 1 comprises a personal computer 2 and a MODEM 3,
The modular terminal 5 of the mobile phone 4 is connected to the EM 3. The modular terminal 5 receives an analog signal for a telephone line from the data transmission device 1. Voice is input to and output from the handset unit 6, and this voice is converted into an analog signal for a telephone line. The switching unit 7 selects one of the analog signals and outputs it to the wireless telephone unit 8 in order to prevent interference between the analog signal from the modular terminal 5 and the analog signal from the handset unit 6. As a selection method, for example, the presence or absence of an input from the modular terminal 5 is detected based on the voltage / current between the terminals of the modular terminal 5, and if there is an input, an analog signal from the modular terminal 5 is input. If there is not, the automatic switching for selecting the analog signal from the handset unit 6 or the manual switching for selecting by operating the switch is performed by the operator. The wireless telephone unit 8 converts the analog signal from the switching unit 7 into a wireless signal for a mobile phone and outputs it to the telephone network 9. The data receiving device 10 comprises a MODEM 11 and a personal computer 12, and a telephone network 9 is connected to the MODEM 11.

Next, the operation of the above embodiment will be described. When transmitting and receiving voice, the voice transmitted and received from the handset unit 6 is converted into an analog signal. This analog signal is selected by the switching unit 7 and output to the wireless telephone unit 8.
In the wireless telephone unit 8, the analog signal is converted into a wireless signal, output to the telephone network 9, and transmitted / received via the telephone network 9. On the other hand, when transmitting the data of the data transmitting device 1 to the data receiving device 10, the personal computer 2 of the data transmitting device 1 outputs the data to the MODEM 3, and the MODEM 3 converts the data into an analog signal for a telephone line, Output to the modular terminal 5 of the mobile phone 4. This analog signal is selected by the switching unit 7 and output to the wireless telephone unit 8. The wireless telephone unit 8 converts the analog signal into a wireless signal and outputs it to the telephone network 9. The telephone network 9 receives the wireless signal, converts the wireless signal into an analog signal on the way, and outputs the analog signal to the MODEM 11 of the data receiving apparatus 10.
The MODEM 11 converts the analog signal into data and outputs it to the personal computer 12.

Another embodiment of the present invention is shown in FIG. The data transmission device 21 is composed of the personal computer 2, the mobile phone 24 is provided with the serial terminal 13 and the MODEM 23, and the other parts are formed in exactly the same manner as the mobile phone 4 of the above-mentioned embodiment. In such an embodiment, the serial terminal 1 of the mobile phone 24
3 is from the personal computer 2 of the data transmission device 21 to RS-232
A signal such as C is received and converted by the MODEM 23 into an analog signal for a telephone line. Since the other points are the same as those of the above embodiment, the description thereof will be omitted.

[0011]

As described above, according to the present invention, it is possible to directly transmit the data collected at the site where there is no wired telephone facility, and the data can be transmitted more quickly.
