TECHNICAL FIELD OF THE INVENTION
The present invention relates to a theft monitoring system.
[0002]
[Prior art]
2. Description of the Related Art In recent years, many cases have occurred in which vehicle-mounted electronic devices such as navigation devices and audio devices are stolen while being parked. As such anti-theft measures for in-vehicle electronic devices, for example, a device in which an anti-theft function is added to a navigation device is known (for example, see Patent Document 1). In this navigation device, when it is detected that the navigation device is detached from the vehicle while in the security mode (alert mode), it is determined that the vehicle is stolen, and the navigation device after the theft cannot be operated normally. . The setting and release of the security mode can be performed by inputting an ID code that can be freely determined by the user (owner). In addition, the user can set a position such as a home in advance, and automatically set the security mode when the vehicle arrives at the set position.
[0003]
In recent years, not only the vehicle-mounted electronic devices but also the vehicle itself may be stolen. As a countermeasure against theft of a vehicle, for example, a mobile terminal device equipped with a position detection unit for detecting the current position of the vehicle based on a signal from a GPS satellite or the like or a wireless communication unit is installed in a place where the thief can not see. It is known that such information is stored (for example, see Patent Document 2). When the mobile terminal device is set in the security mode (monitoring set mode) and there is a position confirmation request from a user, a security company (emergency response center), or the like, the mobile terminal device detects its own vehicle position. , And notifies the user of the position information. As a result, the user can confirm the vehicle position and can monitor an abnormality such as theft of the vehicle. Further, when the security mode is released at a place other than the preset home position, the mobile terminal device determines that the security mode is abnormal, and notifies the user or the security company of the occurrence of the abnormality. I have. Further, to such a mobile terminal device, a movement detection device utilizing a vibration detection principle for detecting vibration generated due to movement of a vehicle or the like is connected, and an abnormality is detected based on the vibration detection signal. There is also known one that immediately informs a security company or the like (for example, see Patent Document 3).

[Problems to be solved by the invention]
However, in the conventional navigation device having the anti-theft function (Patent Document 1), the occurrence of theft itself can be suppressed unless the thief knows that the navigation device cannot operate normally after the theft. is not. The same applies to the theft of the vehicle itself. On the other hand, when the above-mentioned conventional mobile terminal devices (Patent Documents 2 and 3) detect any abnormality such as theft of an on-vehicle electronic device or the movement of a vehicle, the abnormality occurs together with the position information of the vehicle. Is reported to a security company or the like, and the security company or the like can quickly dispatch a response person to the position where the abnormality has occurred to take action, and the anti-theft effect is high. However, the mobile terminal must be installed and placed out of the sight of the thief, so when setting or canceling the security mode, the mobile terminal must be removed from the location where the mobile terminal was installed and operated. And it was inconvenient to use.
[0006]
Therefore, it is preferable that the in-vehicle electronic device having a display such as a navigation device can be used as a user interface, and the security mode of the theft monitoring device such as the mobile terminal device can be set from the in-vehicle electronic device. Alternatively, it is preferable that when the vehicle arrives at a preset position, the engine is shut off and the security mode is automatically set at the same time. However, in order to perform the setting operation from the vehicle-mounted electronic device side, it is a precondition that the vehicle-mounted electronic device is powered on. When the power is on, the engine is running, so even if the user has just set the security mode, the theft monitoring device may detect the vibration of the car etc. there were. On the other hand, the same applies to the case where the security mode is automatically set according to the arrival position of the car. When the engine is turned off, the power supply of the on-vehicle electronic device is shut off, so that a setting error or the like cannot be displayed to the user. There is. For this reason, even when the user intends to set the security mode, there is a possibility that the security mode is not actually set.

[0029]
The I / F unit 27 is an interface for inputting and outputting various signals between the navigation device 2 and the theft monitoring device 3.
[0030]
Next, the main configuration of the theft monitoring device 3 will be described. The operation mode of the theft monitoring device 3 has an operation mode in addition to the security mode described above. When the security mode is set, the theft monitoring device 3 performs a theft monitoring operation. Switching between the driving mode and the security mode is performed in accordance with the security mode setting process executed by the control unit 21 of the navigation device 2.
[0031]
As shown in FIG. 1, the theft monitoring device 3 exchanges various signals with the control unit 31, the storage unit 32, the vibration detection unit 33, the position detection unit 34, the communication control unit 35, and the navigation device 2.

Specifically, various control programs stored in the storage unit 32 are read out, and various processes such as a password verification process, a theft detection process, and a theft notification process are executed in cooperation with the control programs.
[0033]
More specifically, in the security code verification process, when the security code is input together with the security mode setting process start command signal from the navigation device 2, the control unit 31 stores the security code in the security code storage area 32 a of the storage unit 32. It functions as a verification unit that verifies the match between the two passwords by comparing the password with the stored password, and transmits the verification result to the navigation device 2.
[0034]
When both passwords match by the password verification process, the control unit 31 enters a standby state until a security mode start signal is supplied from the navigation device 2. Then, when the security mode start signal is supplied, the control unit 31 immediately shifts the movement monitoring device 3 to the security mode, and executes the theft monitoring operation (theft detection processing and theft notification processing).
[0035]
In addition, the control unit 31 includes a timer for counting a predetermined time (for example, several tens of seconds) set in advance and a counter for counting the frequency. In the security mode, the control unit 31 performs a theft occurrence detection process. In the theft occurrence detection processing, the control unit 31 activates the vibration detection unit 33, counts the number of vibrations when a detection signal indicating the presence of vibration is input from the vibration detection unit 33, and when the detection signal exceeds a predetermined frequency, Judge as abnormal. If there is no vibration for a predetermined time, the counter is cleared.
[0036]
Further, when the control unit 31 determines that there is an abnormality in the theft occurrence detection process, the control unit 31 performs a theft notification process. In the theft notification process, the control unit 31 detects the current position from the position detection unit 34 and controls the communication control unit 35 to notify the occurrence of theft to the outside via a wireless communication line together with the position information.
[0037]
The storage unit 32 is configured from a ROM or the like, and has a password storage area 32a in which a password is stored in advance. In addition, the storage unit 32 stores various programs and the like necessary for the control unit 31 to execute the above-described processes.
[0038]
The vibration detection unit 33 is activated when the theft monitoring device 3 is set to the security mode, and detects vibration in the vehicle. As such a vibration detection unit 33, for example, a vibration detection sensor that accommodates a conductive ball contact made of a metal ball between two plate-shaped terminals can be configured. In the vibration detection sensor configured as described above, the conductive ball contact comes into contact with both terminals when stationary, and the terminals are turned on. When the conductive ball contact rolls in the housing portion and momentarily separates from the terminals during vibration, the terminals are connected. Chattering occurs. Using this, vibration is detected, and a detection signal indicating no vibration is output to the control unit 31 when the terminals are ON, and a detection signal indicating vibration is detected when chattering occurs. .
[0039]
The position detection unit 34 detects the current position of the vehicle equipped with the theft monitoring device 3 and also functions as a position detection unit. The position detection unit 34 includes a GPS antenna 34a, and transmits from a GPS satellite via the GPS antenna 34a.

[0040]
The communication control unit 35 has an antenna 35a, establishes a wireless communication line with a wireless base station, and transmits and receives wireless signals. Thereby, based on the control signal input from the control unit 31, a theft occurrence signal and position information are notified to a predetermined contact address such as a user's home or a security company via the base station. In addition, when a request for transmission of the position information of the own vehicle position is requested from a user, a security company, or the like, the position information detected by the position detection unit 34 is reported to a predetermined contact address in response to the request.
[0041]
The I / F unit 36 is an interface for inputting and outputting various signals between the theft monitoring device 3 and the navigation device 2.
[0042]
The power supply unit 38 includes a chargeable / dischargeable secondary battery or the like, and supplies a predetermined drive power to each unit of the theft monitoring device 3. When the ignition switch of the car is ON, the power supply unit 38 is charged by receiving the supply of power from the battery of the car.
[0043]
Next, the operation of the theft monitoring system 1 will be described.
As an initial setting for operating the theft monitoring system 1, the user can register a personal identification number in the navigation device 2. When the password registration request is made by the user, the control unit 21 of the navigation device 2 displays a password input screen (FIG. 3) on the display unit 24a. When a password is input by the user via the touch panel 24b, the input password is stored in the password storage area 23a of the storage device 23. By registering the password in advance, it is possible to save the trouble of inputting the password every time the security mode is set.
[0044]
In addition, as an initial setting, the user can register a home or a frequently visited place as a security start point in the storage device 23. When the vehicle arrives at the security start point, the security mode setting process can be started by the control unit 21 without any special operation by the user.
[0045]
Next, a security mode setting process executed by the control unit 21 will be described with reference to FIG.
First, the control unit 21 issues a security mode setting process start command input when the security mode setting button 51 displayed on the input display unit 24 is touched or the vehicle arrives at the previously registered security start point. The presence or absence of a signal is monitored (step S1).
[0046]
When the security mode setting process start command signal is input (step S1: Y), the control unit 21 reads the user's password stored in the password storage area 23a of the storage device 23, and the I / F unit 27, The personal identification number is output to the theft monitoring device 3 via the I / F unit 36 (step S2). The control unit 31 of the theft monitoring device 3 collates the personal identification number input from the navigation device 2 with the personal identification number stored in the storage unit 32, and performs a personal identification number verification process for verifying that the two personal identification numbers match. The verification result is transmitted to the navigation device 2.
[0047]
Next, the control unit 21 determines, based on the verification result input from the theft monitoring device 3, that the two passwords match, that is, that the password registered in the navigation device 2 is correct (step S3: Y). Then, a security mode reservation message is displayed on the display unit 24a (step S4). At this time, the theft monitoring device 3 enters a standby state waiting for the supply of the security mode start signal from the control unit 21.
[0048]
If both passwords do not match by the password verification process, that is, if the password stored in the password storage area 23a is incorrect (step S3: N), the process proceeds to step S5. In step S5, the control unit 21 displays on the display unit 24a a message indicating that the transition to the security mode has failed, such as "Do not automatically enter the security mode.", "Reset the password". At the same time, a password input screen is displayed.
[0049]
In step S6, when the user inputs a new password, the control unit 21 rewrites the password stored in the password storage area with the new password. Then, the process returns to step S1, and the operations from step S1 to step S3 are repeatedly executed.
[0050]
Next, after displaying the security mode reservation message in step S4, when the control unit 21 determines that the engine has been turned off based on the detection signal input from the power supply detection unit 26 (step S7: Y), the theft monitoring device Then, a security mode transition operation is performed by supplying a security mode start signal to the terminal 3 (step S8), and the security mode setting process ends.
[0051]
At this time, the theft monitoring device 3 receives the supply of the security mode start signal from the control unit 21, and the control unit 31 activates the vibration detection unit 33 to start the security operation of the theft monitoring device 3.
[0052]
As described above, according to the present embodiment, when the security mode of the theft monitoring device 3 is set, the user only has to touch the security mode setting button 51, so that the user can easily set the security mode. Also, the security mode can be set when a vehicle arrives at a security start point such as a home position.
[0053]
Further, when the security mode setting button 51 is pressed or the vehicle arrives at the security start point, various signals are automatically transmitted and received between the navigation device 2 and the theft monitoring device 3, and the security mode setting process is performed. . At this time, if the password stored in the navigation device 2 matches the password stored in the theft monitoring device 3, that is, if the security mode can be entered, the display unit 24a displays the security mode reservation transition. Since the message is displayed, the user can know that the theft monitoring device 3 will surely shift to the security mode.
[0054]
Further, in the present embodiment, even when the personal identification number output from the navigation device 2 matches the personal identification number of the navigation device 2, the theft monitoring device 3 does not immediately start the theft monitoring operation and the car engine is turned off. In addition, since the theft monitoring operation is started at the same time, there is no possibility that an abnormality is detected due to vibration of the vehicle or the like until the engine is turned off.
[0055]
If the password registered in the navigation device 2 does not match the password stored in the theft monitoring device 3 for some reason, the display section 24a of the navigation device 2 displays "Automatically enter security mode." No "," Please reset your password "and so on. Therefore, it is possible to prevent the user from turning off the car engine without knowing that the password registered in the navigation device is incorrect. Therefore, according to the present embodiment, it is possible to cause the theft monitoring device 3 to reliably perform the theft monitoring operation.
[0056]
Further, according to the present embodiment, since the theft monitoring device 3 includes the position detection unit 34, when the theft occurs, it is possible to notify the user or the like of the theft together with the position information of the vehicle. Thereby, the anti-theft effect can be enhanced.
[0057]
It should be noted that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the gist of the present invention.
For example, in the above-described embodiment, the navigation device 2 has been described as an example of the in-vehicle electronic device. However, the in-vehicle electronic device of the present invention is not limited to this, and may be a car audio device or a television receiver. There may be. In short, when the user sets the security mode, a display means capable of displaying a setting procedure, a confirmation of the setting, and the like, a command signal for starting the security mode processing, and a user's password can be input. Any device may be used as long as it has input means.
[0058]
