  The embodiment will be described with reference to FIG. The mobile communication device 1 is a mobile terminal device such as a PHS (Personal Handy-phone System) or a mobile phone, and includes a portable container 2, a wireless transmission / reception unit 3, a positioning reception unit 4, a microphone 5, a speaker 6, and a keyboard 7. , Display 8, digital camera 9, nonvolatile memory 10, various sensors 11, main battery 12, sub-battery 13, charging circuit 14, switch circuit 15, power supply terminal 16, external terminal 17, and control unit 18. The wireless transmission / reception unit 3 has an antenna 19. The positioning receiver 4 has an antenna 20. The antennas 19 and 20 may be inside the portable container 2 or may be exposed to the outside. The positioning receiver 4, the microphone 5, the digital camera 9, and various sensors 11 constitute a sensor that collects situation information.

  The wireless transmission / reception unit 3 performs wireless communication with the wireless base station 34 using power from the main battery 12, and the following three configurations are conceivable. One is a configuration having only a call function, the other is a configuration having only a data communication function, and the other is a configuration having both a call function and a data communication function. The call function is a function for making a voice call. For example, one caller utters the word “Hello” while the other caller speaks with the word “Yes”. is there. The data communication function is a function for bidirectionally transmitting / receiving characters, symbols or images (still images, moving images, or both images).

  The positioning receiver 4 receives the satellite signal from the positioning satellite 33 and creates the position information of the mobile communication device 1 and detects “latitude” and “longitude” as the position information of the mobile communication device 1. A GPS sensor is configured. The microphone 5 is a device that collects voice and sound, converts them into electric signals, and outputs them. The speaker 6 is a device that converts an electrical signal into sound or sound and outputs the sound. The keyboard 7 includes a large number of keys constituting the input device of the control unit 18. Many keys include a numeric key, a power switch 21, a transmission switch, a function key, and the like. The display 8 constitutes an output device for visualizing the output information of the control unit 18.

  The digital camera 9 constitutes a device for inputting captured images (still images, moving images, or both images) to the control unit 18. The digital camera 9 may be a digital camera that takes only a still image, a digital camera that takes only a moving image, or a digital camera that takes a combined image of both a still image and a moving image. If the digital camera 9 is composed of a digital camera that takes only still images, it is possible to reduce power consumption and memory capacity usage compared to other digital cameras. The main battery 12 is a battery that supplies DC power to each electrical component of the mobile communication device 1. The sub-battery 13 is a battery that supplies direct-current power to each electrical component of the mobile communication device 1 in place of the main battery 12 over the period of battery removal or power-off.

  The charging circuit 14 is a circuit that charges the sub battery 13 when charging the main battery 12. For example, when a power supply line (not shown) is connected to the commercial power supply and the power supply terminal 16 of the mobile communication device 1, and AC power is supplied from the commercial power supply to the charging circuit 14 via the power supply line and the power supply terminal 16, The charging circuit 14 converts the AC power supplied to the DC power of the voltage used for the portable communication device 1, and the charging circuit 14 supplies the DC power to the main battery 12 and the sub battery 13 for charging.

  The switch circuit 15 is a circuit that switches the power supply source from the main battery 12 to the sub-battery 13 by a power supply switching signal from the switching means 27. By the switching operation of the switch circuit 15, DC power is supplied from the sub battery 13 to the control unit 18. In the switching operation of the switch circuit 15, if the supply of DC power to the control unit 18 is interrupted even for a moment, the process of the control unit 18 is interrupted at the time of the interruption, and thus such a phenomenon occurs. For example, during the switching period from the main battery 12 to the sub-battery 13, direct current power is supplied to the control unit 18 from a capacitor (not shown) provided in the mobile communication device 1 or controlled from the sub-battery 13. After supplying DC power to the unit 18, the switch circuit 15 operates so as to cut off the supply of DC power from the main battery 12 to the control unit 18.

  The nonvolatile memory 10 is a recording medium for recording status information. In this embodiment, the positional information collected by the positioning receiver 4, the voice information collected by the microphone 5, the image information collected by the digital camera 9, and the various information collected by the various sensors 11 are used as the status information in the nonvolatile memory 10. To be recorded. The various sensors 11 are composed of, for example, one or more of a temperature sensor, an altitude sensor, an atmospheric pressure sensor, and an acceleration sensor. Therefore, various information detected by the various sensors 11 includes information “temperature” detected by the temperature sensor, information “elevation” detected by the altitude sensor, information “pressure” detected by the pressure sensor, It consists of one or more information of “gravity”, “number of vibrations” and “tilt” detected by the acceleration sensor.

  The control unit 18 includes a CPU 23, ROM 24, RAM 25, detection means 26, switching means 27, measurement means 28, and collection means 29. Based on the control by the CPU 23, the control unit 18 performs modulation to put the voice input from the microphone 5 on the transmission wave and outputs it to the radio transmission / reception unit 3, while taking out the voice from the reception wave input from the radio transmission / reception unit 3. Demodulate and output to the speaker 6. The CPU 23 operates while using the RAM 25 in accordance with a program stored in the ROM 24 and controls the operation of each electrical component of the mobile communication device 1. The detection means 26, the switching means 27, the measurement means 28, and the collection means 29 are embodied by the operation of the CPU 23.

  The detecting means 26 detects whether the main battery 12 is removed, the power switch 21 is turned off or out of service area, and when the main battery 12 is removed, the main battery removal detection signal is switched to the switching means 27 or the measuring means. When the power switch 21 is detected to be off, a power switch off detection signal is output to the switching means 27 and the measuring means 28. When it is detected that the power switch 21 is located outside the service area, the out-of-service detection signal is output to the measurement means 28. Output. Note that the case where the mobile communication device 1 is located within the range may be described as being within the range or simply within the range, and the case where the mobile communication device 1 is located outside the range may be described as being outside or simply outside the range.

  The switching unit 27 outputs a power switch signal to the switch circuit 15 based on the input of the main battery removal detection signal or the power switch off detection signal from the detection unit 26. The measuring means 28 measures the period with the power from the main battery 12 or the sub battery 13 and includes a first counter 30, a second counter 31, and a third counter 32. The first to third counters 30 to 32 perform a counting operation in synchronization with a signal obtained by dividing the clock signal necessary for the operation of the CPU 23, and may be replaced with a timer (not shown) attached to the CPU 23. Good.

  The measuring means 28 controls the first counter 30 when the main battery removal detection signal, the power switch off detection signal or the out-of-service detection signal is input, and the first count value counted by the first counter 30 is the first set value. When the second counter 31 is reached, the second counter 31 is controlled, and when the second count value counted by the second counter 31 reaches the second set value, the third counter 32 is controlled. The first set value is a period for determining whether the main battery 21 is removed, the power switch 21 is turned off, or the out-of-service period is short-term or long-term, and the second set value is a period for collecting information. The set value is a period in which the collection of status information is periodically started, and these first to third set values are written in the ROM 24 in advance.

  The collection unit 29 removes the main battery 12 by the detection unit 26 or turns off the power switch 21 or the out-of-service detection period reaches a predetermined set value, and the positioning receiver 4, the microphone 5, the digital camera 9, and the various sensors 11. The status information detected by operating is stored in the nonvolatile memory 10. For example, the collecting means 29 stores the status information detected by operating the positioning receiver 4, the microphone 5, the digital camera 9, and the various sensors 11 based on the start of the counting operation of the second counter 31 in the RAM 25, and the second counter 31 The status information is written from the RAM 25 to the nonvolatile memory 10 based on the stop of the count operation of 31.

  Devices other than the mobile communication device 1 illustrated in FIG. 1 will be described. Reference numeral 33 denotes a positioning satellite which transmits satellite signals (satellite message (data layer) and code (code layer)) to the mobile communication device 1. A satellite signal from the positioning satellite 33 is transmitted to the positioning receiver 4 via the antenna 20. Reference numeral 34 denotes a radio base station, which transmits and receives audio signals and data signals to and from the radio transmission / reception unit 3 via the antenna 35 connected to the radio base station 34 and the antenna 19 connected to the radio transmission / reception unit 3. .

Reference numeral 37 denotes a monitoring terminal device which reads information in the mobile communication device 1 by telemetry.

  Processing when the main battery 12 is removed, the power switch 21 is turned off, or out-of-service occurs in the mobile communication device 1 will be described with reference to FIGS.

  In FIG. 2, step 101 is a standby state. In step 102, it is determined whether or not the main battery 12 has been removed. If the main battery 12 is loaded, NO is determined in step 102 and the process proceeds to step 103. In step 103, it is determined whether or not the power switch 21 is on. If the power switch 21 is on, NO is determined in step 103 and the process proceeds to step 104. In step 104, it is determined whether the user is out of range. If it is within the range, NO is determined in step 104 and the process returns to step 101. That is, when the three conditions that the main battery 12 is loaded, the power switch 21 is on, and the user is in the area are satisfied, the process returns to the standby state in step 101 of FIG.

  On the other hand, if the main battery 12 has been removed in step 102, YES in step 102 and the process proceeds to step 105. In step 105, the sub-battery 13 is activated and the routine proceeds to step 107. If the main battery 12 is loaded, the process proceeds to step 103. In step 103, if the power switch 21 is off, YES is determined in step 103, and the process proceeds to step 106. In step 106, the main battery 12 is not removed, but since the power switch 21 is off, the sub battery 13 is activated and the main battery 12 is stopped. Then, the process proceeds to Step 107. If it is determined in step 102 that the main battery 12 is loaded (that is, NO is determined) and the process proceeds to step 103 and it is determined that the power switch 21 is on (that is, NO is determined), the process proceeds to step 104. It is determined whether or not the mobile communication device 1 is out of service area. If it is determined in step 104 that the user is out of service area (that is, YES is determined), the process proceeds to step 107. That is, when the main battery 12 is removed, the sub battery 13 is activated. When the power switch 21 is off even if the main battery 12 is loaded, the sub battery 13 is activated, the main battery 12 is stopped, and the main battery 12 is deactivated. When the battery 12 is removed or the power switch 21 is turned off or out of service area occurs, the first counter 30 is activated in step 107. As a result, the first counter 30 performs a counting operation.

  The relationship between the processing in steps 102 to 107 in FIG. 2 and the components in FIG. 1 will be described. The processing in steps 102 to 104 in FIG. 2 is performed by the detection means 26 shown in FIG. The process 106 is performed by the switching unit 27 in FIG. 1, and the process in step 107 in FIG. 2 is performed by the measuring unit 28 in FIG. After step 107 in FIG. 2, the process proceeds to step 108 in FIG.

  FIG. 3 shows processing when the main battery 12 is removed from the standby state or when the power switch 21 is turned off or out of service is restored in a short time and when it continues for a long time. The recovery is a state in which the main battery 12 is returned from removal to loading, a state in which the power switch 21 is returned from off to on, and a state in which the mobile communication device 1 is returned from outside the service area to within the service area. In FIG. 3, in step 108, it is determined whether or not the first count value of the first counter 30 has reached a first set value, for example, 10 minutes. If the first count value has not reached the first set value, NO is determined in step 108, and the process proceeds to step 109. In step 109, it is determined whether or not the main battery 12 is loaded. If the main battery 12 has been removed, NO is determined in step 109 and the process returns to step 108. On the other hand, if it is determined in step 109 that the main battery 12 is loaded, YES is determined in step 109 and the process proceeds to step 110. In step 110, it is determined whether the power switch 21 is on. If the power switch 21 is off, the result of step 110 is NO and the process returns to step 108. On the other hand, if it is determined in step 110 that the power switch 21 is on, YES is determined in step 110 and the process proceeds to step 111.

  In step 111, the main battery 12 is started, the sub battery 13 is stopped, and the process proceeds to step 112. In step 112, it is determined whether or not the user is in the area. If it is out of the service area, NO is made at step 112 and the process returns to step 108. If it is determined in step 112 that the user is in the service area, step 112 is YES and the process proceeds to step 113. In step 113, the count operation of the first counter 30 is stopped, the count value of the first counter 30 is initialized and returned to “zero”, and the standby state of step 101 in FIG. 2 is restored. That is, when the main battery 12 generated from the standby state is removed or the power switch 21 is turned off or out of service is restored in a short period of time that does not reach the first set value (step 108 is NO, step 109 is YES, step 110 is YES, Step 112 is YES), the counting operation by the first counter 30 is stopped, the count value of the first counter 30 is initialized and returned to “zero”, and the standby state is restored.

  If it is determined in step 108 that the count value of the first counter 30 has reached the first set value, YES in step 108 and the process proceeds to step 114. That is, if the main battery 12 removed from the standby state or the power switch 21 is turned off or out of range continues for a long period of time when the first set value is reached (YES in step 108), the count by the first counter 30 is performed in step 114. The operation is stopped, the count value of the first counter 30 is initialized and returned to “zero”. Then, the counting operation of the second counter 31 is started, and the positioning receiver 4, the microphone 5, the digital camera 9 and various sensors 11 are operated.

  The relationship between the processing in steps 108 to 114 in FIG. 3 and the components in FIG. 1 will be described. The processing in steps 108 and 113 in FIG. 3 is performed by the measuring means 28 in FIG. 1 is performed by the detecting means 26 in FIG. 1, the processing in step 111 in FIG. 3 is performed by the switching means 27 in FIG. 1, and the processing in step 114 in FIG. 3 is performed with the measuring means 28 in FIG. This is performed by the collecting means 29. After step 114 in FIG. 3, the process proceeds to step 115 in FIG.

  FIG. 4 shows processing when the main battery 12 is removed from the standby state or when the power switch 21 is turned off or when it is recovered during a period in which the status information is collected continuously for a long time and when it is not recovered. In FIG. 4, in step 115, the collected status information is recorded in the RAM 25, and the process proceeds to step 116. The status information collected in step 115 is referred to as collected information. In step 116, it is determined whether or not the second count value of the second counter 31 has reached a second set value, for example, 5 minutes. If the count value of the second counter 31 has not reached the second set value, NO is determined in step 116 and the process proceeds to step 117. In step 117, it is determined whether or not the main battery 12 is loaded. If the main battery 12 has been removed, NO is determined in step 117, and the process returns to step 115. If it is determined in step 117 that the main battery 12 is loaded, YES is determined in step 117 and the process proceeds to step 118.

  In step 118, it is determined whether the power switch 21 is on. If the power switch 21 is off, NO is made at step 118 and the process returns to step 115. If it is determined in step 118 that the power switch 21 is on, YES is determined in step 118 and the process proceeds to step 119. In step 119, the main battery 12 is started, the sub battery 13 is stopped, and the process proceeds to step 120. In step 120, it is determined whether or not the user is in the area. If it is out of range, the answer is NO in step 120 and the process returns to step 115. If it is determined in step 120 that the user is in the service area, the result of step 120 is YES, and the process proceeds to step 121. In other words, when the main battery 12 generated from the standby state is removed or the power switch 21 is turned off or recovered in a period where the out-of-service area continues to collect status information for a long time (NO in step 116, YES in step 117, step 118 is YES, and Step 120 is YES), in Step 121, the count operation of the second counter 31 is stopped, the count value of the second counter 31 is initialized to "zero", and the positioning receiver 4, the microphone 5, and the digital The operations of the camera 9 and various sensors 11 are stopped, the RAM 25 is initialized, and the process returns to the standby state in step 101 of FIG.

  On the other hand, if the count value of the second counter 31 reaches the second set value, YES is determined in step 116 and the process proceeds to step 122. That is, removal of the main battery 12 generated from the standby state or the power switch 21 is off or the out of service area is continuously collected for a long period of time, and the main battery 12 is removed or the power switch 21 is off or out of service. If it continues without being restored (step 116 is YES), in step 122, the positioning receiver 4, the microphone 5, the digital camera 9, and the various sensors 11 are stopped, the counting operation of the second counter 31 is stopped, and the second counter 31 is stopped. The count value is initialized to “zero” and the process proceeds to step 123. In step 123, the collected information is stored from the RAM 25 into the nonvolatile memory 10, the RAM 25 is initialized, and the process proceeds to step 124. In step 124, the count operation of the third counter 32 is executed.

  4 will be described. The processing of steps 115 and 123 in FIG. 4 is performed by the collecting means 29 in FIG. 1, and the steps 116 and 116 in FIG. The processing in step 124 is performed by the measuring means 28 in FIG. 1, the processing in steps 117, 118, and 120 in FIG. 4 is performed by the detecting means 26 in FIG. 1, and the processing in step 119 in FIG. The switching means 27 performs the processing in steps 121 and 122 in FIG. 4 by the measuring means 28 and the collecting means 29 in FIG. After step 124 in FIG. 4, the process proceeds to step 125 in FIG.

  FIG. 5 shows the next status information continuously without being recovered during the period when the main battery 12 generated from the standby state is removed or the power switch 21 is turned off or out of service area is continuously collected for a long time. The process when recovering during the period until the start of collection and when not recovering is shown. In FIG. 5, in step 125, it is determined whether or not the count value of the third counter 32 has reached a third set value, for example, 20 minutes. If the count value of the third counter 32 has not reached the third set value, NO is determined in step 125, and the process proceeds to step 126. In step 126, it is determined whether the main battery 12 is loaded. If the main battery 12 has been removed, NO is determined in step 126 and the process returns to step 125. If it is determined in step 126 that the main battery 12 is loaded, YES is determined in step 126 and the process proceeds to step 127. In step 127, it is determined whether the power switch 21 is on. If the power switch 21 is off, the result of step 127 is NO and the process returns to step 125.

  If it is determined in step 127 that the power switch 21 is on, YES is determined in step 127 and the process proceeds to step 128. In step 128, the main battery 12 is started, the sub battery 13 is stopped, and the process proceeds to step 129. In step 129, it is determined whether or not the user is in the service area. If it is out of service area, NO is returned in step 129 and the process returns to step 125. If it is within the range, step 129 becomes YES and the routine proceeds to step 130. That is, removal of the main battery 12 generated from the standby state or the power switch 21 is turned off or the status information of the next status information is continuously recovered without recovering in a period where the status information is continuously collected for a long time. When the period is recovered until the collection is started (NO in step 125, YES in step 126, YES in step 127, YES in step 129), in step 130, the counting operation of the third counter 32 is stopped and the third counter 32 is stopped. Is reset to “zero” and the standby state of step 101 in FIG. 2 is restored.

  If it is determined in step 125 that the third count value of the third counter 32 reaches the third set value, YES is determined in step 125 and the process proceeds to step 131. In step 131, the count operation of the third counter 32 is stopped, the count value of the third counter 32 is initialized and returned to “zero”, the count operation of the second counter 31 is executed, and the positioning receiver 4 and the microphone 5 Then, the digital camera 9 and various sensors 11 are operated, and the process returns to the process of recording the collected information in step 115 of FIG.

  5 will be described. The processing of steps 125 and 130 in FIG. 5 is performed by the measuring means 28 in FIG. 1, and the steps 126 and 126 in FIG. 1 is performed by the detecting means 26 in FIG. 1, the processing in step 128 in FIG. 5 is performed by the switching means 27 in FIG. 1, and the processing in step 131 in FIG. 5 is performed by the measuring means 28 in FIG. This is performed by the collecting means 29.

  With reference to FIG. 1, the operation of the components in FIG. 1 based on the processing in FIGS. 2 to 5 will be described. When the power switch 21 of the mobile communication device 1 is turned on by a human operation, the control unit 18 operates with DC power supplied from the main battery 12, and the mobile communication device 1 is in a standby state, When the detection unit 26 detects that the battery 12 is removed or the power switch 21 is turned off, the detection unit 26 sends a battery removal detection signal or a power switch off detection signal to the switching unit 27 and the measurement unit 28. Output. Further, when the detection unit 26 detects a case of being out of service area, the detection unit 26 outputs an out-of-service detection signal to the measurement unit 28. That is, when the main battery 12 is removed or when the power switch 12 is turned off, the power supply source is switched from the main battery 12 to the sub-battery 13, and when the main battery 12 is out of service area, the power supply source is the main battery 12. Remains. Therefore, in the following description of the operation, when the main battery 12 is removed or when the power switch 21 is off, each component in FIG. 1 operates with DC power supplied from the sub-battery 13 and is out of service. In this case, each component shown in FIG. 1 is operated by DC power supplied from the main battery 12.

  Therefore, when the main battery 12 is removed or when the power switch 12 is turned off, the switching means 27 outputs a power switch signal to the switch circuit 15, and the switch circuit 15 is switched from the main battery 12 to the sub battery 13. The control unit 18 continues to operate with the DC power supplied from the sub-battery 13, but when it is out of range, the control unit 18 is supplied from the main battery 12 without switching the switch circuit 15 by the switching unit 27. Continues operation with DC power. Then, the measuring means 28 operates the first counter 30. As a result, the first counter 30 starts the counting operation (refer to the case where step 102 in FIG. 2 is YES, step 103 is YES, and step 104 is YES).

  The first count value of the first counter 30 does not reach the first set value, that is, even when the first counter 30 is counting, the detection means 26 is connected to the battery when the main battery 12 is loaded. When the output of the removal detection signal is canceled and the power switch 21 is returned from OFF to ON, the detection means 26 cancels the output of the power switch OFF detection signal, and when the mobile communication device 1 is located from outside the service area to within the service area The detection means 26 cancels the output of the out-of-service detection signal.

  That is, when the main battery 12 is loaded while the first counter 30 is counting or when the power switch 12 is turned on, the switching means 27 outputs a power switch signal to the switch circuit 15, and the switch circuit 15 The control unit 18 is switched from the battery 13 to the main battery 12 and continues to operate with the DC power supplied from the main battery 12. However, when returning to the service area, the switching means 27 switches the switch circuit 15. Instead, the control unit 18 continues to operate with DC power supplied from the main battery 12. Then, after the measuring means 28 stops the counting operation of the first counter 30, the first count value is initialized and returned to “zero”, and the portable communication device 1 returns to the standby state (step 108 in FIG. 3 is NO, (See the case where step 109 is YES, step 110 is YES, and step 112 is YES).

  In FIG. 1, when the measuring unit 28 determines that the first count value of the first counter 30 has reached the first set value, the first counter is stopped after the measuring unit 28 stops the counting operation of the first counter 30. The first count value of 30 is initialized and returned to “zero” to operate the count of the second counter 31. Further, the measuring means 28 outputs a first set value arrival signal to the collecting means 29, and the collecting means 29 A collection start signal is output to the positioning receiver 4, the microphone 5, the digital camera 9, and various sensors 11. As a result, the positioning receiver 4, the microphone 5, the digital camera 9, and the various sensors 11 collect the situation information and record it in the RAM 25 (see the case where step 108 in FIG. 3 is YES).

  In FIG. 1, for example, as collected information, “latitude” and “longitude” acquired by the positioning receiver 4, “temperature” acquired by a temperature sensor as various sensors 11, and an altitude sensor as various sensors 11 are acquired. “Altitude”, “Barometric pressure” acquired by the barometric sensor as various sensors 11, “Gravity”, “Number of vibrations” and “Tilt” acquired by the acceleration sensor as various sensors 11, Audio information acquired by the microphone 5, Digital This is image information taken by the camera 9.

  If the second count value of the second counter 31 does not reach the second set value, that is, even if the second counter 31 is counting, the detection means 26 is connected to the battery when the main battery 12 is loaded. When the output of the removal detection signal is canceled and the power switch 21 is returned from OFF to ON, the detection means 26 cancels the output of the power switch OFF detection signal, and when the mobile communication device 1 is located from outside the service area to within the service area The detection means 26 cancels the output of the out-of-service detection signal.

  That is, even when the second counter 31 is counting, the switching means 27 outputs a power switching signal to the switch circuit 15 when the main battery 12 is loaded or when the power switch 21 is turned back on. The switch circuit 15 is switched from the sub-battery 13 to the main battery 12 and the control unit 18 continues to operate with the DC power supplied from the main battery 12. The control unit 18 continues to operate with the DC power supplied from the main battery 12 without switching. Then, after the measuring unit 28 stops the counting operation of the second counter 31, the second count value is initialized and returned to “zero”, and the collecting unit 29 detects the positioning receiver 4, the microphone 5, the digital camera 9, and the various sensors 11. Is stopped and the RAM 25 is initialized, and the portable communication device 1 returns to the standby state (NO in step 116 in FIG. 4, YES in step 117, YES in step 118, and step 120). See YES case).

  In FIG. 1, when the measuring unit 28 determines that the second count value of the second counter 31 has reached the second set value, the measuring unit 28 outputs a second set value arrival signal to the collecting unit 29, The collection means 29 outputs a collection end signal to the positioning receiver 4, microphone 5, digital camera 9, and various sensors 11, and the positioning receiver 4, microphone 5, digital camera 9, and various sensors 11 provide status information to the RAM 25. The collection unit 29 initializes the RAM 25 after storing the collected information from the RAM 25 into the nonvolatile memory 10. Further, after the measuring means 28 that has determined that the second count value has reached the second set value has stopped the counting operation of the second counter 31, the second count value is initialized and returned to "zero" to return to the third counter 32. Move. As a result, the third counter 32 starts a counting operation (see the case where step 116 in FIG. 4 is YES).

  Further, in FIG. 1, if the third count value does not reach the third set value, that is, even if the third counter 32 is counting, the detection means 26 removes the battery when the main battery 12 is loaded. When the output of the detection signal is canceled and the power switch 21 is returned from off to on, the detection means 26 cancels the output of the power switch off detection signal, and the detection is performed when the portable communication device 1 is located from outside the service area. The means 26 cancels the output of the out-of-service detection signal. That is, even when the third counter 32 is counting, when the main battery 12 is loaded and the power switch 21 is turned back on from off, the switching means 27 outputs a power switch signal to the switch circuit 15, and the switch The circuit 15 is switched from the sub-battery 13 to the main battery 12 and the control unit 18 continues to operate with the DC power supplied from the main battery 12. Without being performed, the control unit 18 continues the operation with the DC power supplied from the main battery 12. Then, after the measuring means 28 stops the counting operation of the third counter 32, the third count value is initialized and returned to “zero”, and the mobile communication device 1 returns to the standby state (step 125 in FIG. 5 is NO, (See the case where step 126 is YES, step 127 is YES, and step 129 is YES).

  In FIG. 1, when the measuring means 28 determines that the third count value has reached the third set value, the measuring means 28 initializes the third count value after stopping the counting operation of the third counter 32. Return to “zero” and move the second counter 31. Thereby, the second counter 31 starts a counting operation. When it is determined that the third count value has reached the third set value, the measuring means 28 outputs a third set value arrival signal to the collecting means 29, and the collecting means 29 sends the collection start signal to the positioning receiver 4 and the microphone. 5, the digital camera 9, and various sensors 11, and the positioning receiver 4, the microphone 5, the digital camera 9, and the various sensors 11 start collecting status information in the next period according to the second set value and collect it The collected information is recorded in the RAM 25 (see the case where step 125 in FIG. 5 is YES).

  In FIG. 1, for example, when the first set value is set to 10 minutes, the second set value is set to 5 minutes, and the third set value is set to 20 minutes, and the mobile communication device 1 is in a standby state, When the main battery 12 is removed, or when the power switch 21 is turned off or out of service area does not continue for 10 minutes, which is the first set value, the positioning receiver 4, the microphone 5, and the digital camera 9 Various sensors 11 do not start collecting status information. When the main battery 12 is removed, the power switch 21 is turned off, or the vehicle is out of service for 10 minutes, which is the first set value, “latitude”, “longitude”, and “temperature” are used as status information. “Altitude”, “atmospheric pressure”, “gravity”, “number of vibrations”, “tilt”, “sound information”, and “image information” are collected for the second set value for 5 minutes and recorded in the RAM 25, and then the collected information is stored in the nonvolatile memory from the RAM 25. After being stored in the memory 10, the RAM 25 is further initialized. Further, after the collected information is collected for 5 minutes, the case where the main battery 12 is removed, the case where the power switch 21 is turned off, or the case where the power switch 21 is out of service continues for 20 minutes which is the third set value. In this case, the status information is collected for 5 minutes, which is the second set value, and recorded in the RAM 25. After the collected information is stored from the RAM 25 into the nonvolatile memory 10, the RAM 25 is further initialized.

  Next, an example of the form stored in the nonvolatile memory 10 will be described with reference to FIG. When the main battery 12 is removed or when the power switch 21 is turned off, the power supply from the sub-battery 13 of FIG. 1 continues or when the main battery 12 is out of service area, the main of FIG. While the power supply from the battery 12 continues, for example, the collected information collected during the period from 15:00 to 15:05 on January 7, 2010 is stored in the nonvolatile memory 10 as the primary, Collected information collected in the period from 15:25 to 15:30 on January 7, 2010, 20 minutes later, is stored in the nonvolatile memory 10 as the second order. Further, when the main battery 12 is removed or when the power switch 21 is turned off, the power supply from the sub-battery 13 in FIG. While the power supply from the main battery 12 continues, every 20 minutes, the third order and the fourth order are stored. In the state where the collected information is stored in the nonvolatile memory 10 as described above, by outputting the collected information from the portable memory device 1 from the nonvolatile memory 10, for example, in FIG. It is possible to grasp the status of the mobile communication device 1 from 15:30.
