  Further, when the preventive content specifying unit 5 specifies the preventive content data “data protection and dangerous situation notification”, the instruction specifying unit 6 performs the preventive instruction of the storage unit 8 based on the preventive content data “data protection and dangerous situation notification”. With reference to the table, the corresponding instruction data “data saved or deleted and terminal status data transmitted to server” is specified.

  When the instruction specifying unit 6 specifies the instruction data, the control unit 1 transfers the instruction data to the operation control unit 7.

  The operation control unit 7 is a unit that instructs an accident prevention operation based on the instruction data. When the operation control unit 7 receives the instruction data, the operation control unit 7 instructs the operation unit to execute the prevention operation based on the instruction data. In this embodiment, the operation unit is any one of a sound output unit such as a speaker, a vibration unit, and a data protection unit.

  Here, in the present embodiment, a description will be given until the operation control unit 7 executes the preventive operation by an instruction based on the instruction data.

  Upon receiving the instruction data “vibration or voice (only once)”, the operation control unit 7 first activates a microphone (not shown) to indicate the volume level in order to pay attention to the surrounding noise situation. Volume data is acquired and compared with reference volume data held in a memory (not shown). When the volume data is large, in order to alert the user with vibration of the mobile terminal 100, the vibration unit (not shown) is instructed once, and the vibration unit that has received the vibration instruction Execute vibration once.

  On the other hand, when the volume data is small, the operation control unit 7 instructs the voice output unit such as a speaker (not shown) to output a single caution voice in order to alert the user with voice. Upon receiving the output instruction, the voice output unit outputs the caution voice once based on the caution voice data held in the memory (not shown).

  In addition, when receiving the instruction data “vibration or voice (every minute)”, the operation control unit 7 activates a microphone (not shown) to give a warning according to the surrounding noise situation, Volume data indicating the size is acquired and compared with reference volume data held in a memory (not shown). Then, when the volume data is large, in order to alert the user with the vibration of the mobile terminal 100, the vibration unit not shown is instructed to vibrate every minute, and the vibration unit that has received the vibration instruction Repeats vibration every minute until a warning cancellation instruction is received from the user.

  On the other hand, when the volume data is small, the operation control unit 7 instructs the sound output unit such as a speaker (not shown) to output a warning sound every minute in order to alert the user with a sound. The voice output unit that has received the output instruction repeatedly outputs a warning voice based on warning voice data held in a memory (not shown) every minute until a warning cancellation instruction is given by the user.

  In addition, when the operation control unit 7 receives the instruction data “vibration or voice (every minute) from another terminal”, the operation control unit 7 performs a warning according to the surrounding noise state to the other mobile terminal 300 in the same manner as described above. Then, a microphone (not shown) is activated, volume data indicating the volume level is acquired, and compared with reference volume data held in a memory (not shown). When the volume data is large, a vibration instruction signal is transmitted every minute to a vibration unit (not shown) of the other mobile terminal 300 in order to alert the user by the vibration of the other mobile terminal 300. Upon receiving the vibration instruction signal, the vibration unit of the other portable terminal 300 repeats vibration every minute until a warning is issued from the user.

  On the other hand, when the sound volume data is small, the operation control unit 7 sends a warning to the user by a sound from the other portable terminal 300 to a voice output unit such as a speaker (not shown) of the other portable terminal 300. An instruction to output warning sound every minute is issued, and the sound output unit that receives the output instruction outputs warning sound based on warning sound data held in a memory (not shown) every minute until a warning cancellation instruction is received from the user. Output repeatedly.

  When the operation control unit 7 receives the instruction data “vibration or voice (every minute) and terminal status data is transmitted to the server”, the operation control unit 7 first issues a warning to the mobile terminal 100 as described above, and then continues the operation control. The unit 7 instructs a notification unit (not shown) to transmit the terminal status data held in the memory as a dangerous status notification to the management server 200.

  Upon receiving the instruction, the notification unit transmits the latest terminal status data in a memory (not shown) and the terminal status data stored last time to the management server 200. Then, the management server 200 updates the accident history table in the storage unit 25 as will be described later.

  When the operation control unit 7 receives the instruction data “data evacuation or deletion and terminal status data is transmitted to the server”, the operation control unit 7 first performs a data protection unit to evacuate the data stored in the memory of the mobile terminal 100. 9 is instructed to save data.

  The data protection unit 9 is a unit that saves or erases data in response to an instruction. Upon receiving the save instruction, the data protection unit 9 transmits data stored in the memory to the management server 200 as saved data.

  The control unit 20 of the management server 200 is a unit that controls the management server 200 as a so-called CPU, and transfers the saved data to the data protection unit 26 when the saved data is received.

  The data protection unit 26 is a unit that protects the saved data received from the mobile terminal 100, and stores the saved data in the saved data storage unit 27 when the saved data is received.

  When the data protection unit 26 completes storing the save data, the control unit 20 transmits a save completion signal to the mobile terminal 100.

  When receiving the save completion signal, the control unit 1 of the portable terminal 100 transfers the save completion signal to the operation control unit 7.

  Upon receiving the save completion signal, the operation control unit 7 detects that the data save has been completed, and completes the data protection process.

  On the other hand, if the operation control unit 7 does not receive a save completion signal even after a predetermined time has elapsed, the operation control unit 7 determines that the data save has failed, issues a data deletion instruction to the data protection unit 9, and receives the deletion instruction. The data protection unit 9 erases the data stored in the memory and completes the data protection process.

  Subsequently, the operation control unit 7 instructs a notification unit (not shown) to transmit terminal status data held in the memory as a dangerous status notification to the management server 200.

  Upon receiving the instruction, the notification unit transmits the latest terminal status data in a memory (not shown) and the terminal status data stored last time to the management server 200. Then, the management server 200 updates the accident history table in the storage unit 25 as will be described later.

  Next, an explanation will be given until the management server 200 updates the accident history table and sets the risk code of the situation risk code related table by the updated accident history table.

  The control unit 20 of the management server 200 transfers both terminal status data to the table updating unit 21 every time the latest terminal status data and the previously stored terminal status data are transmitted as the danger status notification from the mobile terminal 100.

  The table updating unit 21 is a unit that updates the accident history table. Upon receiving both terminal status data, the table updating unit 21 refers to the situation risk code related table based on the latest terminal status data and matches the latest terminal status data. The accident content data corresponding to the terminal status data to be identified is specified, and the accident content data included in the accident history table is updated based on the specified accident content data and the previously stored terminal status data (see FIG. 7). .

  In addition, the table update unit 21 receives accident case information including terminal status data, accident content data, accident number data, damage amount data, and total sales data indicating the total number of mobile terminals sold from a mobile phone operator or the like (not shown). Each time the data included in the accident history table is updated based on the accident case information. At this time, the table updating unit 21 holds the total sales data in a memory (not shown).

  The danger code setting unit 22 is a part for setting a danger code in each terminal situation data of the situation danger code related table, and the following prevention value calculation formula for calculating a prevention value indicating a predicted damage amount that may be received in the future. Is held in a memory (not shown).

Prevention value calculation formula = A × (B / C) × D (1)

However, A: Average damage amount for each terminal status data B: Number of accidents for each terminal status data C: Total sales of mobile terminals D: Recognition accuracy for each terminal status data

  When the accident history table is updated, the danger code setting unit 22 determines the average damage amount data, the accident number data, and the terminal situation data included in the situation risk code related table included in the updated accident history table. Each recognition accuracy data and total sales data held in the memory are acquired, and each acquired data is applied to the above equation (1) to calculate a preventive value for each terminal status data. Danger codes “1” to “5” are set in order from the calculated terminal status data.

  As described above, since the danger code setting unit 22 periodically updates the situation danger code related table, an optimum danger code that always reflects the latest accident situation is set for each terminal situation data. .

  Next, a description will be given until the danger code table in the storage unit 8 is updated by an instruction from the mobile terminal 100.

  When the user gives an instruction to update the danger code table via an input unit (not shown) of the mobile terminal 100, the control unit 1 of the mobile terminal 100 transmits an update instruction signal to the management server 200.

  When receiving the update instruction signal, the control unit 20 of the management server 200 transfers the update instruction signal to the table creation unit 23.

  The table creation unit 23 is a unit that creates an updated danger code table reflecting the latest accident situation, and upon receiving an update instruction signal, the table creation unit 23 refers to the situation danger code related table in the storage unit 25 and stores the updated danger code table. An updated danger code table is created based on the danger code data.

  When the table creation unit 23 creates the update risk code table, the control unit 20 transfers the created update risk code table to the communication unit 24.

  The communication unit 24 is a unit that transmits an update risk code table. Upon receiving the update risk code table, the communication unit 24 transmits the update risk code table to the mobile terminal 100.

  When receiving the update risk code table, the control unit 1 of the portable terminal 100 transfers the update risk code table to the risk code update unit 10.

  The danger code update unit 10 is a part that updates the danger code table stored in the storage unit 8. Upon receiving the update danger code table, the danger code table stored in the storage unit 8 is updated with the updated danger code table. To do. Thereby, the portable terminal 100 can implement a highly reliable preventive operation based on the danger code table reflecting the latest accident situation.

  In the present embodiment, description has been made until the danger code table is updated by an instruction from the mobile terminal 100. However, even if there is no instruction from the mobile terminal 100, the danger code table is delivered directly from the management server 200 to the mobile terminal 100. A method is also conceivable.

<Operation of Example>
Hereinafter, the prevention operation of the accident prevention system in the present embodiment will be described.

  In this embodiment, as described above, the management server 200 updates the accident history table and the situation risk code related table in the storage unit 25 in a timely manner.

  FIG. 8 is a preventive operation flowchart of the accident prevention system of this embodiment. In this operation description, a description is given until the accident prevention operation “caution” is executed by the mobile terminal 100 by getting on a train that is a terminal situation related to an accident to be prevented by the user who brought the mobile terminal 100. .

  The control unit 1 of the portable terminal 100 periodically outputs a current state detection signal that instructs the current state detection unit 2 to detect the current state based on detection timing data held in a memory (not shown).

  Each time the current status detection unit 2 receives a current status detection signal, the current status detection unit 2 activates an acceleration sensor and a microphone (not shown), and acquires status feature data indicating acceleration “5” and volume “5” (S1).

  When the current state detection unit 2 acquires the situation feature data indicating the acceleration “5” and the volume “5”, the situation determination unit 3 searches a terminal situation determination table in a memory (not shown) based on the situation feature data (S2). Since there is terminal status data “Ride on the train” corresponding to the situation characteristic data, it is detected that the situation should be prevented (S3), and the searched terminal status data “Ride on the train” is dangerous. Transfer to the code identification unit 4.

  Upon receiving the terminal status data “Ride on the train”, the danger code identification unit 4 refers to the danger code table in the storage unit 8 based on the terminal status data “Ride on the train”, and the terminal status data “Train on the train”. The danger code “1” corresponding to “ridden” is specified (S4).

  When the danger code identification unit 4 identifies the danger code “1”, the prevention content identification unit 5 refers to the prevention content table in the storage unit 8 based on the danger code “1”, and the corresponding prevention content data “caution”. Is specified (S5).

  When the preventive content specifying unit 5 specifies the preventive content data “caution”, the instruction specifying unit 6 refers to the preventive instruction table in the storage unit 8 based on the preventive content data “caution”, and the corresponding instruction data “vibration or “Speech (only once)” is specified (S6).

  When the instruction specifying unit 6 specifies the instruction data “vibration or sound (only once)”, the control unit 1 transfers the instruction data “vibration or sound (only once)” to the operation control unit 7.

  Upon receiving the instruction data “vibration or voice (only once)”, the operation control unit 7 first activates a microphone (not shown) to indicate the volume level in order to pay attention to the surrounding noise situation. Volume data is acquired and compared with reference volume data held in a memory (not shown). If the volume data is large, an instruction to vibrate only once is given to a vibration unit (not shown) to alert the user with the vibration of the mobile terminal 100 (S7). The vibration unit performs vibration only once (S8).

  On the other hand, when the volume data is small, the operation control unit 7 outputs a warning voice only once to a voice output unit such as a speaker (not shown) so as to alert the user with voice. An instruction is given (S7), and the voice output unit receiving the output instruction outputs a caution voice once based on the caution voice data held in a memory (not shown) (S8).

  Thereby, a caution, a warning, etc. can be performed in advance as prevention for the user of the mobile terminal 100 in a situation related to an accident to be prevented.

<Effect of Example>
In the accident prevention system of the present embodiment, the danger code table corresponding to the danger code indicating the degree of danger for each terminal status data related to the accident to be prevented by the portable terminal 100, and the prevention contents indicating the accident prevention contents for each danger code The prevention content table corresponding to the data and the prevention instruction table corresponding to the instruction data for executing the prevention operation for each prevention content data are provided, the current state of the mobile terminal 100 is detected, and the detected current state is the terminal state data Determine any one, identify the risk code from the risk code table based on the determined terminal status data, identify the prevention content data from the prevention content table based on the risk code, and prevent based on the prevention content data Since the instruction data is specified from the instruction table and the preventive action based on the instruction data is performed, The user of the portable terminal 100 in a situation where, in advance attention as a prophylactic, or the like can be a warning. Accordingly, it is possible to prevent the user's portable terminal 100 from being damaged such as theft.
