Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crime prevention device mounted on a moving body, particularly an automobile.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent No. 26 has been proposed as a crime prevention device for a moving body.
There is an example shown in No. 65478. This is GPS (Glob
al. Positioning System) etc. are used to specify the position of the moving body, and when an abnormality such as theft is detected while the moving body is stopped, the position specifying means is turned on to notify the abnormality. This is to notify the owner of information including the stop position, which is important in order to do so. Here, in the above-mentioned conventional example, the power of the position specifying means is not always turned on for crime prevention, but the position specifying means is turned on only when an abnormality is detected by the abnormality detecting means to suppress battery consumption. ing.

[0003]

As described above, the conventional security device of this kind is designed to measure the position by the position specifying means and report the position information only when the abnormality is detected. The position will be reported after detecting the abnormality, but during the report, the power of the position specifying device is turned on and power is consumed. If the vehicle is stolen, it may take days to be found, so keeping the power of the position specifying means together with the crime prevention device at all times causes a problem of battery drain. If the battery goes dead, the crime prevention device and the position measurement device will not function, and it will be impossible to search for a stolen car any more.

Even if it operates intermittently, the time required for one-time position specification is the same as GP
Since S is used, it takes several tens of seconds from power-on to startup and position identification. There is a problem that power consumption of several tens of seconds is required for each position identification. In addition, there is a problem in that prompt notification is lacking because a delay of several tens of seconds occurs when a report is made at the moment when an abnormality occurs.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a security device which can reduce the power consumption of the security device as compared with the conventional one and which is excellent in promptness.

[0006]

The invention according to claim 1 for solving the above-mentioned problems is a crime prevention device for a moving body, which is mounted on the moving body and which specifies a position of the moving body. Position information storage means for storing information on a stop position when the main power of the moving body is stopped, which is specified by the position specifying means; abnormality detecting means for detecting an abnormality while the moving body is stopped; When the means detects an abnormality, the output means outputs the information on the stop position stored in the position information storage means to the outside of the moving body as the position information when the abnormality occurs.

The invention described in claim 2 is the same as claim 1
The speed detecting means for detecting the speed of the moving body in the invention described in (1) is provided, and the stop position information is stored in the position information storing means in response to the output from the speed detecting means.

With this structure, the moving body stops,
The position specifying means stores the position information when the main power (specifically, the engine is generally stopped) in the position storing means as the finally stopped position. For example, the position information stored in the position storage means composed of a non-volatile memory does not need to be held by using a power source, and consumption of an auxiliary power source (battery) can be suppressed.

While the vehicle is stopped, the abnormality detecting means detects an abnormality such as mischief or theft that occurs in the moving body, and when the abnormality is detected, the position information stored in the position information storing means is output to the outside of the moving body using the output means. Output to.

Therefore, when an abnormality occurs, it is not necessary to energize the position specifying means each time the abnormality occurs in the conventional example, and the consumption of the auxiliary power supply can be suppressed lower than before.

Further, when the mobile body is stolen, the position where the mobile body is stopped, not the moving position, is important for finding the mobile body. In the present invention, since the position at the time of the stop is stored in the position information storage means, it is sufficient to notify the position information to the security company and the user, and the stop position can be surely found.

Further, in the conventional example, the position specifying means is operated to acquire the position information after an abnormality occurs, but since the normal position specifying means uses GPS, it is started up after the power is turned on. It takes several tens of seconds until the position is specified, and the abnormality notification information is transmitted after waiting for the acquisition of the position specification information, which delays the treatment.

During this time, there is a risk that the moving body may get out of the vehicle, and once the moving body is moved, appropriate measures to prevent the movement cannot be taken.

In the present invention, since the position is notified from the position information storage means, there is less delay than in the conventional example, and the notified security company or user uses the communication line to issue a command or the like that the moving body cannot be immediately moved. It can be given to the moving body, and the effect of preventing theft can be enhanced.

According to a third aspect of the present invention, there is provided a method of operating a security device for a mobile body, wherein when the main power of the mobile body is stopped, the stop position information specified by the position specifying means is used as the position information. Position information storage step of storing in the storage means, abnormality detection step of detecting an abnormality while the moving body is stopped, and information of the stop position stored in the position information storage step when the abnormality detection step detects an abnormality Is output as position information when an abnormality occurs to the outside of the moving body.

With this structure, the moving body stops,
The position specifying means stores the position information when the main power (specifically, the engine is generally stopped) in the position storing means as the finally stopped position. For example, the position information stored in the position storage means composed of a non-volatile memory does not need to be held by using a power source, and consumption of an auxiliary power source (battery) can be suppressed.

During the stop, the abnormality detecting means detects an abnormality such as mischief or theft that occurs in the moving body, and when the abnormality is detected, the position information stored in the position information storing means is output to the outside of the moving body using the output means. Output to.

Therefore, when an abnormality occurs, it is not necessary to energize the position specifying means every time the abnormality occurs in the conventional example, and the consumption of the auxiliary power supply can be suppressed lower than in the conventional case.
Further, when the mobile body is stolen, the position where the mobile body is stopped, not the moving position, is important for finding the mobile body.
In the present invention, since the position at the time of the stop is stored in the position information storage means, it is sufficient to notify the position information to the security company and the user, and the stop position can be surely found.

Further, in the conventional example, the position specifying means is operated to acquire the position information after an abnormality occurs, but since the normal position specifying means uses GPS, it is started up after the power is turned on. It takes several tens of seconds until the position is specified, and the abnormality notification information is transmitted after waiting for the acquisition of the position specification information, which delays the treatment.

During this time, there is a possibility that the moving body may get out of the vehicle, and once the moving body is moved, appropriate measures for preventing the movement cannot be taken. In the present invention, since the position is notified from the position information storage means, the delay is less than in the conventional example, and the security company or the user who has been notified uses the communication line to issue a command or the like that the mobile body cannot be immediately moved. Can be given to, and the anti-theft effect can be enhanced.

BEST MODE FOR CARRYING OUT THE INVENTION Specific embodiments of the security device according to the present invention will be described below in detail with reference to the drawings.

Although the moving body in the embodiments described below is specifically described as an automobile, any type of moving vehicle having a main power (engine) and an auxiliary power source (battery) can be used. . In addition to automobiles, heavy machinery for construction, motor boats, etc. are also included.

FIG. 1 is a general outline of a crime prevention system including a crime prevention device according to an embodiment of the present invention. A mobile unit 1 equipped with a crime prevention device including a position specifying unit, a position information storage unit (not shown), an abnormality detecting unit, and an output unit (included in the communication unit), and an information intermediary. A crime prevention system is composed of the device 2 and the user terminal 3.

In the security device according to the present embodiment, the abnormality detecting means detects the breakage of the window glass, the prying of the door, etc. that occur while the moving body is stopped. Output error notification information to the outside. The abnormality notification information includes the position information at the time of the stop, which is stored in advance in the position information storage means, the type of the abnormality, the occurrence time, and the like.

The abnormality notification information is sent to the information mediating device through the communication line, and the information mediating device judges whether the sent information is correct or important information to be notified to the user terminal. Information determined to be important is sent to the user terminal and notified to the user. Here, the user may be the owner of the moving body, the security company, or both.

Next, referring to FIG. 2, an embodiment of the present invention will be described in comparison with a conventional example. First, the conventional time-lapse diagram shown in the upper part of FIG. 2 will be described.

The conventional position specifying means always turns on the power when the main power of the moving body is moving, and specifies where the moving body is at a predetermined time interval.

Next, when the main power of the moving body is stopped and the vehicle enters a stopped state, the crime prevention device and other devices must be operated by the battery, and in order to prevent the battery from running down, The power is turned off, leaving the other devices.

Also in the conventional example, since the position specification by the position specification means is unnecessary, the power supply of the position specification means is turned off. In this stopped state, the abnormality detecting means is turned on (not shown) and detects that an abnormality has occurred.

Conventionally, once an abnormality is detected, the power of the position specifying means is turned on to determine what the state of the moving body is, and the position specifying information is acquired from the position information providing device (GPS satellite etc.) to specify the position. Then, the fact that there is an abnormality in the information mediating device is transmitted together with the position specifying information.

After that, since the conventional security device monitors the state of the moving body, the power supply of the position specifying means remains on. In such a state, if the main power is not operating and is in a stopped state, the battery will run down, which is a problem.

Further, since it takes time to acquire the position information after detecting the abnormality, there is a problem that a delay occurs from the detection of the abnormality to the output of the abnormality notification information to the outside of the moving body. To do.

Next, with reference to the lower part of FIG. 2, a time course in the embodiment of the present invention will be described. While the main power of the moving body is moving, the power of the position specifying means is turned on, and the position of the moving body is specified at a predetermined time interval.

The movement of the moving body is stopped immediately before the main power of the moving body is stopped. At this time, for example, the position information is acquired from the position information providing device separately from the timing of a predetermined time interval, and the position information is stored in the position information storage means. Memorized in.

After that, the main power of the moving body is stopped, the moving body enters the stopped state, and the power source of the position specifying means is turned off to prevent the battery from being consumed.

Even in this stopped state, the abnormality detecting means is on, and it is possible to detect that an abnormality has occurred. When an abnormality is detected, the security device in this embodiment immediately reads out the position information stored in the position information storage means and transmits it to the outside, for example, the information mediating device.

At this time, without waiting for the position information newly acquired by the position specifying means as in the conventional example, the previously acquired position information at the time of stopping is transmitted as the position information at the time of abnormality. That is the point. The effects described above are obtained by this series of operations.

In order to explain the present embodiment, the one-way information flow from the security device 4 to the user terminal 3 has been shown, but the security system is not limited to one direction, and the current from the user terminal 3 to the present one is not shown. It may be a two-way security system capable of requesting information on the state of the vehicle and controlling the security device.

Next, a flow chart of processing of the conventional example and this embodiment will be shown and will be described step by step.

FIG. 6 is a flow chart of processing of the conventional security device. First, when the main power of the moving body is stopped in ST11, other special processing is not performed, and in ST12, only the processing of turning off the power of the position specifying means is performed, and the processing ends.

When the position specifying information is transmitted, as shown in FIG.
As described in step ST21, after the abnormality detection means detects an abnormality in ST21, the position identification means is activated in ST22, and ST23
At, the position information is acquired from the position information providing means and the place is specified. Then, in ST24, the position specifying information obtained in ST23 is transmitted to the information mediating apparatus.

FIG. 7 is a flow chart of processing of the security device of the present invention. First, in ST31, it is detected that the velocity of the moving body becomes 0, and when the velocity becomes 0, in ST32, the position identifying means 9 already activated acquires the position identifying information.

Next, in ST33, the position specifying information obtained in ST32 is stored in the position information storage means (device) 8. ST34
Then, it is determined whether or not the main power of the moving body has stopped, and if it starts moving again, other processing is performed. When the main power is stopped on the spot, the power of the position specifying means is turned off and the operation is ended.

When transmitting the position specifying information, FIG.
As described in 1., when the abnormality detection means 10 detects an abnormality in ST41, the position identification information stored in ST33 is read from the position information storage device 8 in ST42, and the position identification information is transferred to the information mediation device using the communication means 12 in ST43. Send to 2.

In this embodiment, the position information of the place where the main power is stopped can be surely stored. Further, it is different from the above-mentioned conventional example in that the consumption of the auxiliary power source after the main power is turned off can be suppressed as much as possible.

FIG. 8 is a flow chart of processing of the information mediating apparatus 2. First, when abnormality notification information is sent from the mobile unit in ST51, the information is received in ST52, and the abnormality notification information is transmitted in ST53 to notify the user.

When it is confirmed in ST54 that the user has received the abnormality notification information, the process ends. If the error notification information has not arrived at the user, send it again and repeat until it is confirmed that it has arrived at the user.

FIG. 9 is a specific example of a series of flows in a security system including the security device of the present invention. Here, a series of flows in the case where the moving body whose position is to be specified is a car, and the car shifts to the alert mode (described in detail later) and an abnormality occurs during the alert mode will be described.

During the traveling indicated by, the position specifying means is GPS here, and the GP is used to specify the position.
A GPS satellite is a position information providing means having a function of providing information to S. Cars use GPS,
Get the current position of your vehicle. And position information is GPS
It is stored in a storage device inside or outside of. While the vehicle is self-propelled, the battery power can be used freely, so the GPS power is always on. GPS periodically acquires position information and provides the position information to the driver of the vehicle.

When the vehicle is stopped, turning off the engine of the automobile is equivalent to stopping the main power of the moving body in the present invention. In that case, the GPS acquires position information immediately before turning off the engine. Then, the position information is stored in the storage device.

Then, the vehicle is switched to the warning mode. The alert mode referred to here is a mode set for the vehicle by the user, for example, by operating the remote controller, and is a state in which when the vehicle has an abnormality, the information is delivered to the user.

In the case indicated by, when the glass window of the car is broken to steal something inside, or when the driver forcibly opens the door to drive and escape, the abnormality detecting means of the automobile is activated and the vehicle is connected to the network. The abnormality notification information is notified to the information intermediary device installed in the automobile monitoring center.

The abnormality notification information includes, in addition to the position specifying information, information regarding the time when the abnormality has occurred and the state of the abnormality. The information intermediary device notifies the owner of the vehicle that the vehicle has been stolen by means such as e-mail or telephone.

The owner of the automobile can know the condition of the automobile through the abnormality notification information sent from the information mediating device to his mobile phone or pager.

FIG. 10 is a diagram for explaining the warning mode.
An example of conditions under which the moving body (vehicle) enables the abnormality detecting means is shown below. The alert mode is enabled by one or a combination of a plurality of conditions including the following conditions and other conditions. The vehicle speed sensor determines that the vehicle has stopped. The engine sensor determines that the engine has stopped. It is judged from the lock sensor that it has been locked. The remote control key sensor determines that the user has left the vehicle with the remote control key. The remote control key sensor receives the fact that the user has operated the remote control key.

FIG. 11 shows a concrete example of the abnormality detecting means. An example of conditions under which an automobile detects an abnormality is shown below.

It is judged that the abnormality is detected by one or a plurality of combinations including the following conditions or other conditions. The trunk sensor determines that the trunk has opened. The sound pressure sensor determines that the glass has broken. The bonnet sensor determines that the bonnet has opened. The engine sensor determines that the engine has started. A collision sensor detects a vehicle collision, door prying, etc. The movement of the vehicle (wheels rotated) is determined by the vehicle speed sensor. The acceleration sensor determines the movement of the vehicle (such as when it is placed on a trailer or when it is lifted by a crane or the wheels do not rotate).

FIG. 12 is a diagram of a specific embodiment of the user terminal. If the information intermediary device installed in the automobile monitoring center receives the abnormality notification information and determines that there is abnormality, the automobile monitoring center notifies the user (here, the owner of the vehicle) of the mobile phone or pager. , It is possible to inform the user that the car is abnormal.

In the description of the above embodiment, the vehicle speed sensor or the like is used to detect the stop of the vehicle, and when the stop of the vehicle is detected, the position detecting means is activated to detect the position again. Therefore, even in a system in which the position measurement interval is relatively large, it is possible to secure data close to the abnormal position as the stop position information.

On the other hand, like a recent GPS system, when a device that measures the position at an interval of about 1 second after the stable operation after starting is used, an abnormal position is stored and a stop is stored. The deviation from the position information can be made extremely small.

In such a case, unless the operation of the electronic circuit becomes unstable and the accuracy of the data is impaired, the position specifying information is updated and stored sequentially in the memory having a holding function at intervals of 1 second. As a result, accurate stop position information can be obtained, so it is not necessary to detect the stop itself using the output of the special vehicle speed sensor or the like.

[0094]

As described above, according to the present invention, when the security device is operating on the battery, power is not consumed to acquire position information, so that power consumption can be suppressed. The battery can be prevented from running out.

Further, when the abnormality is detected, the position information already stored is read from the memory and output to the outside, so that there is no delay in the notification to the outside such as the user, and a corresponding correct response is provided. It is possible to secure various measures and to construct a highly safe crime prevention system.
