Description

  The present invention relates to a low power consumption portable wireless communication terminal device that communicates with a remote monitoring device such as a terminal location search application using a public wireless line from a remote monitoring device.

  Conventionally, in order to use a portable wireless communication terminal device with low power consumption, it is necessary to suppress power consumption during standby, and many methods for this purpose have been devised. In the case of a PDC system mobile phone, there is a method of turning off the power of other circuit blocks while leaving the trigger signal detection unit in accordance with the intermittent reception timing defined in RCRSTD-27.

  Another portable wireless communication terminal device (mobile wireless device) is described in Japanese Patent Laid-Open No. 6-177811. This includes a receiving antenna 101, a receiving circuit 103, a demodulating circuit 104, an audio decoding circuit 105, and a transmitting unit for transmitting audio data, which are receiving units for receiving audio data. A transmission antenna 102, a speech encoding circuit 106, a modulation circuit 107, a transmission circuit 108, a timing control circuit 109 that controls timing for the entire mobile radio apparatus, a timer 111, and a connection reception start time and end time in advance. A memory 112 that stores data to be determined, and a power control unit 110 that includes a CPU 113 that controls the on / off of the power based on the timing operation of the timer 111 and the data read from the memory 112, and the connection reception start time Power on the transmitter and receiver of the mobile radio device and turn off at the end time. It is intended to only standby state in the time between the mobile radio device connection acceptance start time and end time.

  In other words, by limiting the allowable reception time for calling a mobile wireless device to each mobile wireless device, the power consumption during standby is reduced, and the power is turned on only between a predetermined standby start time and end time. Alternatively, the power is turned on only during the standby start time and end time designated by the radio communication base station to enable standby, thereby realizing low power consumption.

However, in the portable wireless communication terminal device exemplified by the above PDC system mobile phone and the portable wireless communication terminal device described in JP-A-6-177811, the standby time at the time of full charge is about several hundred hours. Since portable radio communication terminal devices used for telemetering applications and terminal location search applications have few opportunities to be charged, it is desired to extend standby time by further reducing power consumption.

  The present invention has been invented in view of the above-mentioned background art, and its problem is that the waiting time per charge can be lengthened, the call can be made only when the power is turned on, and the power is turned off. It is an object of the present invention to provide a portable wireless communication terminal device that can eliminate unnecessary calls.

  A rechargeable battery drive type equipped with a normal drive mode driven by a normal wireless communication means, a power saving drive mode in which a trigger signal detector for detecting a trigger signal for activation operates, and an ID number of the own device In the portable wireless communication terminal device, the trigger signal detection unit includes a timer unit and a power control unit, and the normal drive mode return time, which is a time to return from the power saving drive mode to the normal drive mode, is the ID number. When the time monitored by the timer reaches the normal drive mode return time, the power saving drive mode returns to the normal drive mode.

  According to the portable wireless communication terminal device of the present invention, by providing a time to turn on and off according to a unique identification number of the own terminal (for example, an ID number of the own device), charging is performed once. The waiting time per hit can be increased.

  Further, for example, when using a remote monitoring device, the remote monitoring device is powered on from the unique number (for example, the ID number of its own device) of the portable wireless communication terminal device registered in the monitoring device. If the ON time can be grasped, it is possible to make a call only when the power is turned on, and it is possible to eliminate an unnecessary call when the power is turned off.

  A portable wireless communication terminal device according to an embodiment of the present application will be described with reference to FIGS. FIG. 1 is a block diagram of a portable wireless communication terminal apparatus according to an embodiment of the present invention, FIG. 2 is a diagram showing a method for determining the power ON / OFF time of the above, and FIG. FIG. 4 is a schematic diagram for explaining a case where the above apparatus is applied to a remote monitoring system. This portable radio communication terminal device 1 includes a normal drive mode driven by normal radio communication means, and a power saving drive mode in which a trigger signal detection unit 7 for detecting a trigger signal for activation is operated. In the rechargeable battery-driven portable wireless communication terminal device 1 that can be used for a public line, the trigger signal detection unit 7 includes a time measuring unit 8 and a power supply control unit 9, and the power saving drive mode is When the normal drive mode return time, which is the time to return to the normal drive mode, is determined as a fixed value according to the ID number of the own device, and when the time monitored by the timer unit 8 reaches the normal drive mode return time, Returning from the power saving drive mode to the normal drive mode.

  The main circuit unit 2 is a circuit for realizing the main functions of the mobile radio communication terminal device 1. This circuit stores a wireless circuit unit 3 for performing wireless communication with a ground station, a peripheral circuit unit 4 such as an interface unit with a display unit or an external device, a unique number of each terminal, and an ID number of its own device. And a memory 6 for storing programs and a CPU 6 for controlling the wireless circuit unit 3, the peripheral circuit unit 4, and the memory 5.

This circuit includes a timer 8 that generates a start trigger signal at a time when the power is to be turned on or off, and a power controller that turns on or off the energization of the main circuit 2 when the trigger signal is detected. 9.

  That is, when the energization to the main circuit unit 2 of the portable radio communication terminal device 1 is ON, the normal drive mode is set, and when the energization to the main circuit unit 2 is OFF, the power saving drive mode is set.

  Next, the operation of the portable wireless communication terminal device 1 will be described.

  When the current time is the notified power-on time, the timer unit 8 generates a trigger signal for the trigger signal detector 7, and the trigger signal detector 7 energizes the main circuit unit 2. . Similarly, when it is time to turn off the power, the timer unit 8 generates a trigger signal to the trigger signal detector 7, and the trigger signal detector 7 cuts off the energization of the main circuit unit 2.

  In the mobile radio communication terminal device 1, the CPU 6 calculates the time at which the power is to be turned on and off from the ID number of the own device (mobile radio communication terminal device 1) stored in the memory 5 and notifies the time measuring unit 8. For example, as shown in FIG. 2, the time at which the power is to be turned on and off is determined from the last digit of the ID number.

  Thereby, in the time other than the specific time zone according to the ID number of the own device, the power supply to the main circuit unit is cut off.

  This operation will be described with reference to the time chart of FIG. This figure shows an example in which the power is turned on when the last digit is 0 minute to 1 minute.
