The terminal 20 also includes a first storage unit 120 that stores various programs, a second storage unit 150 that stores various types of information in advance, and a third storage unit 170 that stores various types of information acquired or generated by the terminal 20.

  As illustrated in FIG. 4, the terminal 20 stores a monitoring mode determination program 122 in the first storage unit 120. The monitoring mode determination program 122 is information for the terminal control unit 100 to determine whether or not the terminal 20 is operating in the monitoring mode. Here, the monitoring mode is a mode for performing an operation of determining whether or not the terminal 20 in FIG. 1 is located in the monitoring zone Z.

As illustrated in FIG. 4, the terminal 20 includes a positioning interval progress determination program 124. The positioning interval progress determination program 124 is information for determining whether or not the time interval for the terminal control unit 100 to perform positioning of the current position of the terminal 20 by the positioning unit 106 of FIG. 4 has elapsed. This time interval is indicated in the positioning interval information 154 stored in the second storage unit 150 of FIG. 4 and is, for example, 10 minutes.
The terminal control unit 100 stores current position information 172 indicating the current position acquired by the positioning unit 106 in the third storage unit 170.

As shown in FIG. A photovoltaic power generation amount measurement program 126 is included. The photovoltaic power generation amount measurement program 126 is information for the terminal control unit 100 to acquire the photovoltaic power generation amount information 174 indicating the photovoltaic power generation amount by the solar power generation unit 104 in FIG. That is, the photovoltaic power generation amount measurement program 126 and the terminal control unit 100 are an example of a power generation amount information acquisition unit.
Specifically, the terminal control unit 100 is based on the photovoltaic power generation amount measurement program 126 and based on the voltage (V) and current (I) generated by the solar power generation unit 104, the photovoltaic power generation amount (W). Is generated. Then, the terminal control unit 100 stores the generated photovoltaic power generation amount information 174 in the third storage unit 170.

  As illustrated in FIG. 4, the terminal 20 includes a photovoltaic power generation amount threshold determination program 128. In the photovoltaic power generation amount threshold determination program 128, the terminal control unit 100 determines whether or not the photovoltaic power generation amount indicated by the photovoltaic power generation amount information 174 is equal to or greater than the photovoltaic power generation amount threshold indicated by the photovoltaic power generation amount threshold information 156. It is information for judging. The photovoltaic power generation amount threshold is information indicating a range in which the terminal 20 is allowed to operate in a normal operation mode, which is a normal operation mode described later, and is an example of a normal operation allowable range. That is, the photovoltaic power generation amount threshold value judgment program 128 and the terminal control unit 100 are an example of a normal operation allowable range inside / outside judgment means.

FIG. 5 is a diagram illustrating an example of the photovoltaic power generation amount threshold information 156.
As illustrated in FIG. 5, the photovoltaic power generation amount threshold information 156 is information indicating each operation mode (described later) of the terminal 20 corresponding to the photovoltaic power generation amount PS (W). Specifically, if the photovoltaic power generation amount PS (W) is 0 watt (W) or more and 1 watt (W) or less, the terminal 20 is set in the power saving mode, and the photovoltaic power generation amount PS (W) is 1. If it is larger than watts (W), it indicates that the normal operation mode is set.
The contents of the normal operation mode and the like described above are shown in the operation mode information 158 stored in the second storage unit 150 in FIG.

FIG. 6 is a diagram illustrating an example of the operation mode information 158.
As shown in FIG. 6, the operation mode information 158 includes GPS corresponding to the battery remaining amount P (%) of the battery 30 in FIG. 2 for each operation mode of the normal operation mode 158a, the power saving mode 158b, and the emergency monitoring mode 158c. This is information indicating the presence or absence of a remaining amount warning notification corresponding to the positioning interval (minutes) by the device 34 and the remaining battery level P (%).

Hereinafter, differences between the respective operation modes will be described.
As shown in FIG. 6, when the remaining battery power P is, for example, greater than 30 percent (%) and less than 50 percent (%), the positioning interval in the normal operation mode 158a is 5 minutes, whereas power saving The positioning interval in mode 158b is 10 minutes. The longer the positioning interval, the shorter the operation time of the GPS device 34, so the power consumption of the terminal 20 is smaller. That is, the power consumption in the power saving mode 158b is smaller than the power consumption in the normal operation mode 158a.
The normal operation mode 158a is an example of the normal operation mode, and the power saving mode 158b is an example of the power saving mode.
Unlike the present embodiment, in the power saving mode 158b, the function of the terminal 20 may be stopped until a predetermined function stop time, for example, 10 minutes elapses. For example, power consumption can be minimized by stopping all functions of the terminal 20 other than the clock 40 (FIG. 2).

  The emergency monitoring mode 158c is an operation mode when the terminal 20 determines that the current position of the terminal 20 is outside the monitoring zone Z in FIG. As shown in FIG. 6, the positioning interval in the emergency monitoring mode 158c is 2 minutes when the battery remaining amount P is greater than 10 percent (%) and not more than 30 percent (%), and the normal operation mode 158a described above. And shorter than in the power saving mode 158b. This is because, when the terminal 20 goes out of the monitoring zone Z, the current position information indicating the current position to the monitoring server in FIG. 1 is obtained by frequently grasping the current position of the user (not shown) of the terminal 20. It is because it is necessary to transmit.

As shown in FIG. 6, in any of the normal operation modes 158a and the like, when the battery remaining amount P becomes 10 percent (%) or less, there is a remaining amount warning notification. For example, the remaining battery level warning notification is displayed on the display device 38 of FIG. 2 by displaying a character string “the battery level is low” to inform the user of the terminal 20 that the battery level is low. It is a notice to do. When the user (not shown) recognizes the notification that the remaining battery level is low, the user consumes all the power of the battery 30 in FIG. 2 by taking measures such as turning off the power of the terminal 20. You can avoid doing that.
The normal operation mode 158a and the like described above are all examples of the monitoring mode.

  As shown in FIG. 4, the terminal 20 has an operation mode setting program 130. In the operation mode setting program 130, the terminal control unit 100 determines whether or not the photovoltaic power generation amount indicated in the photovoltaic power generation amount information 174 is equal to or greater than the photovoltaic power generation amount threshold value indicated in the photovoltaic power generation amount threshold information 156. This is information for setting the terminal 20 to the normal operation mode 158a or the power saving mode 158b based on the determination result. That is, the operation mode setting program 130 and the terminal control unit 100 are an example of mode setting means.

FIG. 7 is a schematic diagram showing an operation mode setting method and the like.
In FIG. 7, a range in which the radius d around the center point 52 a of the building 52 is 1 kilometer (km) is defined as the monitoring zone Z.
If the photovoltaic power generation amount is larger than 1 watt (W) which is the photovoltaic power generation amount threshold value (see FIG. 5) based on the operation mode setting program 130, the terminal control unit 100 performs the normal operation mode 158a (see FIG. 6). ). For example, when the terminal 20 is located outdoors at point A in FIG. 7 and the amount of photovoltaic power generation is greater than 1 watt (W), the normal operation mode 158a is set.

On the other hand, when the terminal 20 is located at a point B indoors and the amount of solar power generation is 1 watt (W) or less, the terminal 20 is set to the power saving mode 158b.
Therefore, the terminal 20 can operate for a long time by setting the power saving mode 158b in a place where power supply cannot be received. This means that the position of the user (not shown) of the terminal 20 can be monitored for a long time.

As shown in FIG. 4, the terminal 20 has a monitoring zone inside / outside determination program 132. The monitoring zone inside / outside determination program 132 is acquired by the terminal control unit 100 using the positioning unit 106, and the current position of the terminal 20 indicated by the current position information 172 stored in the third storage unit 170 is the monitoring zone shown in FIG. This is information for determining whether or not it is within Z.
That is, the monitoring zone inside / outside determination program 132 and the terminal control unit 100 are an example of a movement allowable range inside / outside determination means.

As shown in FIG. 4, the terminal 20 has an emergency call information transmission program 134. When the terminal control unit 100 determines that the current position of the terminal 20 is outside the monitoring zone Z in FIG. 7 based on the monitoring zone inside / outside determination program 132 described above, the emergency call information transmission program 134 70 is information for transmitting emergency call information including terminal identification information 152 stored in the second storage unit 150 and current position information 172 stored in the third storage unit. That is, the emergency call information transmission program 134 and the terminal control unit 100 are an example of a terminal-side notification unit.
Here, the terminal identification information 152 is information for identifying the terminal 20 from other terminals and the like, for example, the telephone number of the communication device 36 (see FIG. 2) of the terminal 20.
The emergency call information described above may include a call type information (not shown) indicating the type of the emergency call information. The report type information indicates, for example, the type of urgency that increases the degree of urgency such as normal report, emergency call, and super-emergency call as the number of times that the terminal 20 determines that the current position is outside the monitoring zone Z increases. Information. By including the report type information in the above emergency call information, the degree of urgency can be notified to the monitoring server 70 in FIG. 1 and the transfer destination of the emergency call information.
Furthermore, the emergency call information described above may include the above-described photovoltaic power generation amount information 174.

As shown in FIG. 4, the terminal 20 has a monitoring mode setting program 136. The monitoring mode setting program 136 is used when the terminal control unit 100 determines that the current position of the terminal 20 is a point C outside the monitoring zone Z in FIG. This is information for setting the emergency monitoring mode 158c of FIG.
That is, the monitoring mode setting program 136 and the terminal control unit 100 are an example of emergency monitoring mode setting means.

As shown in FIG. 4, the terminal 20 has a battery remaining amount confirmation program 138. The battery remaining amount confirmation program 138 is information for the terminal control unit 100 to confirm the remaining amount of the battery 30 in FIG. That is, the battery remaining amount confirmation program 138 and the terminal control unit 100 are an example of a battery remaining amount confirmation unit. The terminal control unit 100 stores the remaining battery level information 176 indicating the confirmed remaining battery level in the third storage unit 170.
Details of the battery remaining amount confirmation method performed by the terminal control unit 100 based on the battery remaining amount confirmation program 138 will be described later.

As shown in FIG. 4, the terminal 20 has a positioning interval setting program 140. The positioning interval setting program 140 is information for the terminal control unit 100 to set the activation interval of the GPS device 34 in FIG. 2 based on the remaining battery level of the battery 30.
That is, the positioning interval setting program 140 and the terminal control unit 100 are an example of positioning interval setting means.
Specifically, based on the positioning interval setting program 140, the terminal control unit 100, for example, in the power saving mode 158b (see FIG. 6), the remaining battery level is greater than 50% (%) and less than 100% (%). If it is, the positioning interval is set to 5 minutes. On the other hand, in the power saving mode 158b, when the remaining battery level is more than 30% (%) and not more than 50% (%), the positioning interval is set to 10 minutes. That is, as the remaining battery power P decreases, the activation interval of the GPS device 34 in FIG. 2 is set longer. Thus, the power consumption of the terminal 20 can be reduced by setting the activation interval of the GPS device 34 to be long.
Thereby, the terminal 20 can operate for a longer time even in a place where power supply cannot be received.

Part 250.

As illustrated in FIG. 9, the monitoring server 70 stores a terminal identification program 208 in the server first storage unit 206. The terminal identification program 208 is information for the server control unit 200 to identify the terminal 20 from other terminals based on the terminal identification information 152 (see FIG. 4) included in the emergency call information acquired from the terminal 20. is there.
That is, the terminal identification program 208 and the server control unit 200 are examples of terminal identification means.
Specifically, the server control unit 200 makes an inquiry about the terminal identification information 222 stored in the server second storage unit 220 and the above-described terminal identification information 152 based on the terminal identification program 208, so that the terminal 20 Identify The terminal identification information 222 is identification information of a plurality of terminals 20, for example, information indicating telephone numbers.
When the server control unit 200 identifies the terminal 20 as another terminal, the server control unit 200 stores the terminal identification information 152 in the server third storage unit 250 as the identified terminal information 252.
Further, the server control unit 200 associates the identified terminal information 252 with the terminal position information 254 indicating the current position of the terminal 20 included in the emergency call information, and the reception indicating the time when the emergency call information is received from the terminal 20. The item information 256 is stored in the server third storage unit 250.

The above is the configuration of the moving object monitoring system 10 according to the present exemplary embodiment. Hereinafter, an example of the operation will be described mainly using FIGS. 10, 11, and 12.
10, FIG. 11 and FIG. 12 are schematic flowcharts showing an operation example of the moving object monitoring system 10 according to the present embodiment.

The following description will be made on the assumption that the current position of the terminal 20 is a point B in the building 52 of FIG. 7 and the amount of photovoltaic power generation of the solar cell panel 32 of FIG. 2 is less than 1 watt (W).
First, the terminal 20 determines whether or not the current operation mode is the monitoring mode (step ST1 in FIG. 10).
When determining that the current operation mode is the monitoring mode, the terminal 20 determines whether or not the activation interval of the GPS device 34 in FIG. 2 has elapsed (step ST2).
When the terminal 20 determines that the activation interval of the GPS device 34 has elapsed, the terminal 20 measures the amount of solar power generated by the solar battery panel 32 in FIG. 2 and indicates the amount of solar power generated 174 (see FIG. 4). Is acquired (step ST3). That is, step ST3 is an example of a power generation amount information acquisition step.

Subsequently, the terminal 20 determines whether or not the photovoltaic power generation amount exceeds the photovoltaic power generation amount threshold value (1 watt (W)) indicated in the photovoltaic power generation amount threshold information 156 (see FIG. 5) ( Step ST4). That is, step ST4 is an example of a normal operation permissible range determination step.
As described above, since the terminal 20 is located at the point B in FIG. 7 and the amount of photovoltaic power generation is less than 1 watt (W), the terminal 20 indicates that the amount of photovoltaic power generation is equal to the threshold value of photovoltaic power generation. Judge that it does not exceed.

Subsequently, the terminal 20 sets the power saving mode 158b (see FIG. 6) based on the determination result that the photovoltaic power generation amount in step ST4 does not exceed the photovoltaic power generation amount threshold (step ST5). As described above, the power saving mode 158b is an operation mode that consumes less power than the normal operation mode 158a. Therefore, the terminal 20 can operate for a long time by setting the power saving mode 158b in a place where power supply cannot be received.
When it is determined in step ST4 that the photovoltaic power generation amount exceeds the photovoltaic power generation amount threshold, the normal operation mode 158a is set (step ST41).
That is, step ST5 and step ST41 are an example of a mode setting step.

  Subsequently, the terminal 20 measures the current position by the positioning unit 106 (see FIG. 4), and generates current position information 172 indicating the current position (step ST6). That is, step ST6 is an example of a current position information generation step.

Subsequently, the terminal 20 determines whether or not the current position is within the monitoring zone Z (step ST7 in FIG. 11). That is, step ST7 is an example of a determination step for determining whether the movement is within the allowable range.
Since the current position of the terminal 20 is the point B in FIG. 7 and within the monitoring zone Z, the terminal 20 determines that the current position is within the monitoring zone Z.

Subsequently, the terminal 20 checks the remaining battery level of the battery 30 in FIG. 2 (step ST8). That is, step ST8 is an example of a battery remaining amount confirmation step. In step ST8, the terminal 20 checks the remaining battery level. A method for calculating the remaining battery level, which is a precondition for checking the remaining battery level, will be described with reference to FIG.
FIG. 12A is a diagram illustrating an operation example in which the battery capacity is corrected in a state where the battery 30 is charged to a possible limit (fully charged state). Since the battery capacity of the battery 30 itself may fluctuate due to deterioration of the battery 30 over time, the terminal 20 corrects the battery capacity from the voltage in the fully charged state (step ST100).
The terminal 20 stores information indicating the corrected battery capacity in the third storage unit 170 (see FIG. 4) as battery remaining amount information 176 (step ST101). That is, in step ST101, the battery remaining amount information 176 is updated.

FIG. 12B shows that the terminal 20 calculates the remaining battery level when the solar cell panel 32 of FIG. 2 does not generate solar power and the GPS device 34 and the communication device 36 of FIG. It is a figure which shows an operation example.
As shown in FIG. 12B, the terminal 20 calculates the remaining battery level from the voltage of the battery 30 (step ST200), and information indicating the calculated remaining battery level is set as the remaining battery level information 176 in the third storage unit 170. (See FIG. 4) (step ST201). That is, in step ST201, the battery remaining amount information 176 is updated.

FIG. 12C shows a case where the terminal 20 calculates the remaining battery power when all or part of the solar battery panel 32 of FIG. 2, the GPS device 34 and the communication device 36 of FIG. 2 are operating (operating state). It is a figure which shows the operation example to do. If the solar cell panel 32 performs solar power generation, the battery 30 is charged. On the other hand, when the GPS device 34 and / or the communication device 36 operate, the battery 30 is discharged.
As shown in FIG. 12 (c), the terminal 20 integrates the amount of electricity from the charge / discharge current (step ST300).
Then, the remaining battery level is calculated based on the remaining battery level indicated in the remaining battery level information 176 stored in the third storage unit 170 and the integrated amount of electricity obtained by integrating in step ST300 (step ST301).
Then, the calculated battery remaining amount is stored in the third storage unit 170 as new battery remaining amount information 176 (step ST302). That is, in step ST302, the battery remaining amount information 176 is updated.
As described above, the terminal 20 continuously calculates the remaining battery level and updates the remaining battery level information 176 in the fully charged state, the resting state, and the operating state.
Then, in the above-described step ST8, the terminal 20 checks the current battery remaining amount that is continuously calculated and indicated in the updated battery remaining amount information 176.

After confirming the remaining battery level, the terminal 20 checks the remaining battery level against the remaining battery level threshold (step ST9). Specifically, the terminal 20 includes 10% (%), 30% (%), 50% (%), and 100% (%), which are included in the operation mode information 158 (see FIG. 6). Queries each battery remaining threshold.
As described above, since the terminal 20 is set to the power saving mode 158b (see FIG. 6), if the remaining battery level is 15% (%), for example, 10% (%) and 30%. It is determined that the value falls within a range of 10 percent (%) to 30 percent (%) defined by each battery remaining amount threshold value (%).

Subsequently, the terminal 20 sets an execution interval of step ST3, which is an example of a positioning step, based on the remaining battery level (step ST10). That is, step ST10 is an example of a positioning interval setting step.
Specifically, the terminal 20 operating in the power saving mode 158b has a range of 10 percent (%) to 30 percent (%) if the remaining battery level is 15 percent (%) (see FIG. 6). The positioning interval is set to 30 minutes.
As shown in FIG. 6, the activation interval of the GPS device 34 in FIG. 2 is set longer as the remaining battery power P decreases. Thus, the power consumption of the terminal 20 can be reduced by setting the activation interval of the GPS device 34 to be long.
Thereby, the terminal 20 can operate for a longer time even in a place where power supply cannot be received.

In step ST7 in FIG. 11, when the terminal 20 determines that the current position is outside the monitoring zone Z in FIG. 7, the emergency notification information is transmitted to the monitoring server 70 in FIG. 1 (step ST71). Step ST71 is an example of an emergency call information transmission step.
In step ST7, when the terminal 20 determines that the current position is outside the monitoring zone Z in FIG. 7, the terminal 20 sets the emergency monitoring mode 158c (see FIG. 6) (step ST72). Step ST72 is an example of an emergency monitoring mode setting step.
