Give to 2. In the decoder 52, the individual number in the radio call data is compared with the unique number in the ROM 53, and when the two match, the acoustic driver 56 is driven and the MP
The alarm data is given to U54 and stored. The acoustic driver 56 drives the buzzer unit 57 and the light emitting diode 58 to cause the buzzer unit 57 to generate a ringing tone and emit ringing light. Further, the MPU 54 drives the display driver 59 to display a necessary alarm signal on the LCD display 60 as a picture, a character, a font, or the like. As a result, the administrator carrying the pager 5 is notified that the automobile 2 has an abnormality.

According to the present embodiment, the pager 5 is shared by the normal radio call and the terminal device of the crime prevention system. Therefore, it is not necessary to carry a receiver for the crime prevention system separately and the general purpose Pager 5 can be used.

Further, according to the present embodiment, the transmission device 4 can be used in any area where the pager 5 can be used and the transmission device main body 8 is connected to the radio base stations 21a, 21b, .... It is possible to know the abnormality that has occurred in the vehicle 2 in which the is installed, and it is possible to take predetermined measures.

Further, according to this embodiment, data input /
The security mode can be canceled by setting a personal identification number on the display panel 7 and entering the personal identification number or the like when using the automobile 2. Therefore, it is possible to prevent the detection of an undesired abnormal state.

In the present embodiment, the sensor 6 detects the engine start of the automobile 2 (a state in which electric power is supplied to the starter (ST) circuit), but the present invention is not limited to this. The opening may be detected, or a vibration sensor may be attached to the window glass as the sensor 6, and even if the window glass is broken, it may be detected that an abnormality has occurred in the automobile 2.

Further, in the present embodiment, the crime prevention target object has been described as the automobile 2, but the invention is not limited to this, and a warehouse, a store, a home or the like may be the crime prevention target object. In this case, a sensor for detecting the opening of the door or the window may be provided, a vibration sensor for detecting the destruction of the door or the door may be provided, or a disaster prevention sensor such as a smoke detector may be provided. Then, for example, when there is no warning release input, when an abnormal state detection signal is generated from each of the sensors, it may be determined that an abnormality has occurred in the crime prevention target object.

Further, in the present embodiment, the pager is used as the terminal device 5, but the present invention is not limited to this, and the mobile phone, the wired telephone of each home, the so-called cordless telephone, the facsimile device, and the like. It may be a terminal device. In this case, in the case of a mobile phone, a home-use wired phone, or a cordless phone, a voice message "car 2
An abnormality has occurred in "." Also, in the case of a facsimile machine,
It is sufficient to notify the abnormality by letters.

(Embodiment 2) Next, a crime prevention system according to a second embodiment will be described. The configuration of the crime prevention system according to the present embodiment is substantially the same as the configuration according to the first embodiment shown in FIGS. 1, 2, and 3, so the operation will be mainly described. 5 and 6 are flowcharts showing the operation of the crime prevention system according to this embodiment. First, the owner of the automobile 2 inserts the key into the ignition switch 32 and turns the ignition switch 32 to the accessory or engine on position.
0, power is supplied to the wireless unit 11 (S50
0). Further, when the ignition switch 32 is turned to the starter side, power is supplied to the starter 36 and the starter 36 operates. At the same time, the voltage of the output side 6a of the sensor 6 becomes high level, and this high level signal is sent to the CPU 16 via the input / output device 17.

Then, the CPU 16 determines whether or not the transmission flag is set (set). Here, the transmission flag is a flag indicating whether or not to send a warning to the communication network 3. The outgoing flag is not set (S501
If NO), the operation mode of the CPU 16 transits to the setting mode (S601). Even when the call origination flag is set (YES in S501), the operation mode of the CPU 16 shifts to the setting mode when the destination of the warning is not set (YES in S502).

After changing to the setting mode (S601), C
The PU 16 starts counting the timer (S60
2). Then, the CPU 16 determines whether or not the key operation is performed (S603), and when the key operation is performed (S603).
If YES in step 603, the CPU 16 executes the processing in step S605 and subsequent steps. On the other hand, when the key operation is not performed within the predetermined time (for example, 10 seconds) after the transition to the setting mode (S
If NO in 604), the CPU 16 shuts off the power source of the controller 9 and the like (S508).

After the CPU 16 detects that the key operation has been performed (YES in S603), the CPU 16 determines whether or not to set the transmission flag (S605). That is, when the user tries to set the transmission device in a state where a warning can be issued (YES in S605), the user operates the key to set (set) the transmission flag (S6).
07). On the other hand, when the user prohibits the generation of the warning (NO in S605), the user operates the key and resets (does not set) the transmission flag (S606). The content of the outgoing flag set in this way is written in the nonvolatile memory 18.

After that, the user determines whether or not to set or change the recipient (S608). Setting the recipient code (phone number of the pager who receives the alert),
When it is determined that the change is made (YES in S608),
The user operates the keys to input the recipient code. Then, the CPU 16 writes the input recipient code in the nonvolatile memory 18 (S609). On the other hand, when the user determines not to set or change the recipient (NO in S608), the CPU 16 does not rewrite the recipient code in the nonvolatile memory 18,
The processing from step S610 is executed. In S610, the user inputs setting items other than the reception flag and the receiver code (for example, whether or not to simultaneously issue a warning to a plurality of pagers).

Subsequently, the user determines whether or not all the setting work has been completed (S611), and when the user desires to continue the setting work (NO in S611), the user To the security device. Then, CPU
In step 16, the process after S605 is executed again. On the other hand, when the user determines that all the setting work is completed (S6
In the case of 11), the user inputs to the transmitting device 4 that the setting work has been completed. Then, the CPU 16 shuts off the power source of the controller 9 and the like (S508). However, at this time, the power is still supplied to the other electric circuit of the automobile 2. Further, since the transmission flag and the reception destination code are written in the non-volatile memory 18, the stored contents of the transmission flag and the reception destination code are retained even after the engine is stopped and the ignition key 32 is turned off.

After that, it is assumed that the user again rotates the ignition key 32 from the accessory side to the starter side, and the controller 9 or the like of the transmitter 4 is activated. At this time,
Since the outgoing flag and destination have already been set (S
YES in 501 and YES in S502), the transmitting device 4 transmits a radio wave of a warning signal from the antenna 12. The radio wave of the warning signal is transmitted to the pager owned by the user on the driver's seat through the communication network 3. As a result, a warning sound or the like is emitted from the pager. However, in this case, since it is clear that the user has started the vehicle, it is unlikely that the user will mistakenly recognize the warning. Next, CPU
16 starts counting the timer (S5
04), it is determined whether a key operation has been performed (S50).
5). When the key operation is performed within a predetermined time (several seconds) (YES in S505), the CPU 16 determines whether the content of the key operation is to turn on the setting mode (S506). When the content of the key operation is to turn on the setting mode (YES in S506), the CPU 1
The operation mode of 6 transits to the setting mode. This allows
It is possible to change the transmission flag and the transmission destination. On the other hand, if the content of the key operation is something other than that of turning on the setting mode (NO in S506), the CPU 6 shuts off the power (S508). In addition, when no key operation is performed within the predetermined time (YES in S507)
Also, the CPU 6 shuts off the power (S508).
As described above, when the user does not perform any key operation within the predetermined time, it is considered that the user has no intention of setting the transmission flag or the like. Therefore, in such a case, the power of the crime prevention device can be automatically cut off after a predetermined time has elapsed, thereby reducing the labor for powering off the crime prevention device.

After that, it is assumed that a fraudulent person attempts to steal a vehicle parked in a parking lot, for example. When a cheating person releases the door lock of the user's vehicle by some means and rotates the ignition switch 32 to the starter side, the output of the sensor 6 becomes high level. CPU16
Detects that the output of the sensor 6 has become high level, then determines whether or not the transmission flag is set (S5).
01). At this time, since the transmission flag has already been set (YES in S501), the CPU 16 further determines whether or not the transmission destination code is set (S502). At this time, the destination code is already set (S
Yes at 502). Therefore, the CPU 16 sends an alarm signal to the pager specified by the destination code. A user far away from the vehicle can detect that his vehicle is being stolen by the warning issued by the pager. After that, the user can prevent the theft of his / her vehicle by taking predetermined measures (for example, reporting to the police). After the CPU 16 sends a warning signal to the pager (S503), the security device can transit to the setting mode (S504 to S50).
It becomes 7). However, since the warning signal has already been transmitted to the pager, the user can detect that the abnormality has occurred in the vehicle 2 even if the setting contents are changed by a cheating person.

According to the security system of the present embodiment, the following effects can be obtained in addition to the effects of the first embodiment described above. That is, in this embodiment, since the outgoing call flag and the destination can be set without inputting the personal identification number or the like, the security of the crime prevention system is lowered even if the personal identification number is leaked. There is no such thing.

The key operation described above can be performed using the data input / display panel 7. The user
By operating the keys while looking at the display section of the data input / display panel 7, data can be input interactively. As a data input method, there are a method of moving a cursor on the display unit, a method of using a ten-key pad, and the like.
