It is provided with a communication interface unit 5 for communicating. In FIG. 1, 11 is an antenna, 12 is a microphone, and 13 is a speaker, which operate in cooperation with the transceiver 1.

The operation unit 2 is an encoder for setting a transmission / reception frequency for the transmission / reception unit 1, a transmission / reception unit control key for instructing transmission / reception function control, and an instruction key for instructing a command for controlling the controlled wireless communication device 6. Is equipped with.

Further, the control unit 3 is provided with a central control unit (CPU), a ROM in which a program and command data for controlling the controlled wireless communication device 6 are stored, a RAM for storing data and an input / output port, and the control unit Functionally, 3 is a transmission / reception unit control means 31 for controlling the functions of the transmission / reception unit 1 based on an instruction from an encoder and a transmission / reception unit control key. A connection detection means 32 for detecting the occurrence of a failure, a mode switching means 33 for switching between a command data transmission mode and a transmission / reception mode based on the detection result by the connection detection means 32, and a display control means 34 for controlling the display of the display unit 4. A command data storage unit 35, and a command data search / transmission control unit 3 for controlling command data retrieval / transmission 6 and.

In the portable wireless communication device of this embodiment, when controlling the controlled wireless communication device 6, the communication interface unit 5 and the controlled wireless communication device 6 are electrically connected by the bus 61. A predetermined voltage generated from the power supply voltage of the controlled wireless communication device 6 is applied to a predetermined line in the bus 61 from the controlled wireless communication device 6 by connecting the bus 61. In the portable wireless communication device of this embodiment, when it is used as a wireless communication device, the connection by the bus 61 is removed.

The operation of the portable wireless communication device of the present embodiment configured as described above will be described according to the flowchart of FIG.

When the portable wireless communication device of this embodiment is powered on, it is checked whether or not the communication line, that is, the bus 61 is connected to the portable wireless communication device (step S1). This check is made depending on whether or not the above-mentioned voltage is detected by the connection detecting means 32 on a predetermined line in the bus 61. When it is determined that the bus 61 is not connected, the transmission / reception mode of operating as a portable wireless communication device is set, and the transmission / reception unit control key of the operation unit 2 is pressed or the encoder is operated. Wait (step S2). Switching to the transmission / reception mode is performed under the control of the mode switching control means 33.

When it is determined in step S2 that the transmission / reception unit control key has been pressed, or when the encoder has been operated, the transmission / reception unit 1 is controlled to the operating state and the transmission / reception unit control key or An operation process based on the encoder is performed (step S3), and then repeatedly executed from step S1. The operation processing of step S3 includes frequency division ratio control of the PLL circuit, transmission / reception switching control, and accompanying display control. Frequency division ratio control, transmission / reception switching control, etc. are performed under the control of the transmission / reception unit control means 31, and display is performed under the control of the display control means 34.

When it is detected in step S1 that the bus 61 is connected, the command data transmission mode for controlling the controlled wireless communication device 6 is switched under the control of the mode switching control means 33. When it is detected in step S1 that the bus 61 is connected, that is, when the command data transmission mode is set, the data transmitted from the bus 61 is received and received via the communication interface unit 5.

When it is determined that there is a communication request, the controlled wireless communication device 6 sends the data. Data is received by serial communication (step S5).

It is checked whether or not there is data that requires display processing among the data received in step S5 (step S6). If it is determined in step S4 that there is no communication request, step S5 is skipped, and step S6 is executed following step S4. If it is determined in step S6 that there is data that needs to be displayed, the display based on the data that needs to be displayed is displayed on the display unit 4 under the control of the display control means 34, and then repeatedly executed from step S1. (Step S7).

If it is determined in step S7 that there is no data that needs to be displayed, it is checked whether the instruction key has been pressed on the operation unit 2 (step S8), and the instruction key has not been pressed in step S8. If it is determined that the step S8 is performed, the process is repeated from step S1 subsequent to step S8. When it is determined in step S8 that the instruction key has been pressed, command data corresponding to the pressed operation key is transmitted through the communication interface 5 by serial communication following step S8, and the controlled wireless communication device 6 To the bus 61 via the bus 61, and then repeatedly executed from step S1 (step S9).

In the command data sent in step S 9, the command data assigned to the instruction key is retrieved from the command data recording means 35 by the command data retrieval and transmission means 36 based on the output from the pressed instruction key. The command data retrieved under control is sent out under the control of the command data retrieval / delivery means 34. Upon receiving the command data, the controlled wireless communication device 6 is controlled to a state based on the command data.

In the above-described embodiment, the case where command data is communicated via the bus 61 by serial communication is illustrated, but command data may be transmitted and received by optical means such as an optical fiber. Good. Further, the transmitting / receiving unit 1 may be of a single band or of a multi band.
