Embodiments according to the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 shows an external view of a portable wireless terminal according to the first embodiment of the present invention, and FIG. 2 shows a functional block diagram. The portable wireless terminal 100 includes an antenna 101, a wireless unit 102, a microphone 103, a speaker 104, a sensor 105, a sensor On / Off switch 106, a control unit 107 such as a CPU, a power / volume switch 108, a channel switch 109, and a PTT button. 110, a monitor 111, and a keypad 112.

  The portable wireless terminal 100 is configured as a business wireless device used in field work, for example. As shown in FIG. 1, on the outer surface of the portable wireless terminal 100, in addition to the antenna 101, the microphone 103, the speaker 104, the monitor 111, and the keypad 112, switches (switches or buttons) for switching various functions may be used. ), A PTT button 110 for executing transmission, a channel changeover switch 109 for switching a call channel, and a power supply / volume changeover switch 108 for controlling the volume of the speaker 104 and On / Off of the power supply of the terminal.

  A portable commercial radio for public safety is characterized by a large radio, a heavy weight, and a large switch. However, for example, in the case of a fire fighting radio, a fire department staff may use it while wearing it on a waist belt or the like while wearing a thick glove for extinguishing fire when used by removing it from the waist belt. For this reason, it has been difficult to operate switches such as changing the call channel and reception volume on site.

  Therefore, the portable wireless terminal 100 according to the present invention incorporates a sensor 105 that detects a predetermined external stimulus in order to facilitate function switching with one hand, and pushes the sensor 105 for controlling On / Off. A button type sensor On / Off switch 106 is arranged on the outer surface of the terminal. The control unit 107 receives external stimulus detection information detected by the sensor 105 and state information of the sensor On / Off switch 106, and based on these information, various functions of the portable wireless terminal 100 are provided. Perform the switch. For example, when the user presses the sensor On / Off switch 106, the control unit 107 determines the output of the sensor 105 that changes due to external impact, external vibration, external action, etc. Switch etc.

As described above, according to the first embodiment, various functions of the commercial radio can be easily switched with one hand even in a site in a bad environment, and the convenience for the user is improved.
Hereinafter, specific examples of the configuration of the sensor 105 and the function switching method will be described according to each embodiment.

(Example 1: 3D acceleration sensor)
In the first embodiment, a case where a three-dimensional acceleration sensor is used as the sensor 105 will be described. FIG. 3 shows an external view of the portable wireless terminal according to the first embodiment and definitions of axes of the three-dimensional acceleration sensor, and FIG. 4 shows a functional block diagram. 3 and 4, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 3 and 4, the portable wireless terminal 100A includes a three-dimensional acceleration sensor 1051 and detects a change in the external three-dimensional acceleration of the portable wireless terminal 100A. The control unit 107 performs function switching of the portable wireless terminal 100A based on the information on the acceleration change output from the three-dimensional acceleration sensor 1051 and the state information of the sensor On / Off switch 106.

  Here, when the mobile radio terminal 100A is in a standby state, the user presses the sensor On / Off switch 106, and as shown in FIG. The case of shaking twice will be described. An output schematic diagram of the three-dimensional acceleration sensor 1051 in this case is shown in FIG.

  The control unit 107 recognizes that the waveform has been swung to the right twice based on the shape and size of the waveform, the number of times, and the time interval T, and switches the function of the terminal. By discriminating the shape of the waveform, it is possible to recognize even when it is swung to the left.

  As a function switching method, for example, when ch1, ch2, ch3, and ch4 are assigned to each switch state of the channel switch 109 in order and the channel switch 109 is currently set to ch1, the sensor On / Off If the switch 106 is pressed and swung to the right twice, the function is switched to ch2. This function switching state is maintained, and when the sensor On / Off switch 106 is pressed again and shaken twice to the right, the function is switched to ch3. That is, when the sensor On / Off switch 106 is pressed and swung to the right twice, the function is switched in order from ch1 to ch4, and when swung to the left twice, the function is switched in order from ch4 to ch1.

  These function changes are held until the channel changeover switch 109 is changed. When the channel changeover switch 109 is changed, the channel changeover switch 109 has priority and the channel set by the channel changeover switch 109 becomes effective.

  In the above, the example of shaking to the right twice has been described. However, when the number of shaking, the shaking interval, the shaking direction, and the shaking strength are combined, or when shaking left and right, the back of the terminal is not only shaken. Various function switchings can be assigned to various external stimuli, such as increasing the reception volume when tapping with a finger at regular intervals within a certain time. Of course, it is possible to extend to a combination of external stimulation in the y-axis direction, external stimulation in the z-axis direction, x-axis, y-axis, and z-axis.

(Example 2: optical sensor)
In the second embodiment, a case where an optical sensor is used as the sensor 105 will be described. FIG. 6 shows an external view of the portable wireless terminal according to the second embodiment, and FIG. 7 shows a functional block diagram. 6 and 7, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 6 and 7, the infrared light emitting unit 1052 and the infrared light receiving unit 1053 are installed on the outer surface of the portable wireless terminal 100 </ b> B so as to face each other. For example, the infrared light emitting unit 1052 is always in an issuance state, and when there is no shielding object between the two, the infrared light receiving unit 1053 always detects infrared rays, and when there is a shielding object, the received light power decreases. To do. The infrared light receiving unit 1053 outputs the detected received light power information to the control unit 107. The control unit 107 receives the received light power information detected by the infrared light receiving unit 1053 and the state information of the sensor On / Off switch 106. Based on these information, the decrease in the received light power matches a predetermined pattern. If it is determined, the switching of various functions of the portable wireless terminal 100 is executed.

  For example, with the user pressing the sensor On / Off switch 106, a finger or the like is passed between the infrared light emitting unit 1052 and the infrared light receiving unit 1053, and the light from the infrared light emitting unit 1052 is regularly spaced and the number of times. In the case of blocking, the control unit 107 determines based on the received light power information of the infrared light receiving unit 1053, and performs function switching of the portable wireless terminal 100B.

  As shown in FIG. 8, for example, when the portable wireless terminal 100 </ b> B is in a standby state, the distance between the infrared light emitting unit 1052 and the infrared light receiving unit 1053 is determined with the user pressing the sensor On / Off switch 106. In the case of blocking twice at the interval T, the control unit 107 determines that a predetermined operation has been performed based on the waveform shape of the received light power, the decrease, the number of times, and the time interval of the received light power, and switches the function of the portable wireless terminal 100B. As the predetermined pattern, a plurality of patterns can be prepared using a combination of the number of times and the time interval.

  In addition, the infrared light emitting unit 1052 can be issued not only constantly but also repeatedly turned on and off to reduce power consumption. In addition, the infrared light emitting unit 1052 and the sensor On / Off switch 106 can be linked to reduce power consumption.

  When the periphery of the portable wireless terminal 100B is sufficiently bright, it is possible to remove the infrared light emitting unit 1052 and use an optical sensor that reacts with visible light instead of infrared light instead of the infrared light receiving unit 1053.

  In the first and second embodiments, the function switching is assigned to the terminal by the channel switching function, the volume control function of the speaker 104, the brightness adjustment function of the monitor 111, the power On / Off function of the terminal, and the like. There are no restrictions on the functions.

  In addition, the sensor On / Off switch 106 of this terminal is mounted for the purpose of avoiding erroneous detection or the like. However, when erroneous detection is permitted, or error switching such as function switching due to a complicated external stimulus that is not erroneously detected. When a means that does not cause detection is used, it is possible to remove the sensor On / Off switch 106 and always permit function switching by an external stimulus.

  In the first and second embodiments, the function switching method in the standby state is described. However, regardless of the standby state, the function switching can be performed regardless of the state of the terminal, such as during transmission, reception, and when the power is off. It is also possible to implement.

In the station, the user performs communication by setting the channel changeover switch 109 to ch1 (step S1). When there is a dispatch command and the user switches the sensor On / Off switch 106 to On, the control unit 107 outputs voice guidance such as “sensor switching is now possible” from the speaker 104 (step S2). .

  When arriving at the site, the user applies an external stimulus to the portable wireless terminal 100 in order to switch to the channel (ch2) used at the site. When the control unit 107 detects a predetermined external stimulus based on the output of the sensor 105 (step S3), the control unit 107 switches the function to ch2 (step S4). A method using the three-dimensional acceleration sensor of the first embodiment or the optical sensor of the second embodiment can be applied to the function switching execution determination in step S3.

  When the user completes the field work and returns to the office, and the user switches the sensor On / Off switch 106 to Off, the control unit 107 outputs voice guidance such as “Sensor switching has been turned off” from the speaker 104. (Step S5). The control unit 107 automatically switches to ch1 physically set by the sensor On / Off switch 106 (step S6).

  According to the second embodiment, when the sensor On / Off switch 106 is turned off, the physical setting state of the channel selector switch 109 automatically matches the actual channel setting.
