Abstract

PROBLEM TO BE SOLVED: To improve operability and to maintain high burglarproof property by interlocking a locking device with an alarm device. SOLUTION: When a lock mechanism 2 is locked or unlocked, a locking device fitted to a wheel, etc., of a motorcycle informs an alarm device 11 of the lock/unlock state with a state information signal. After collating the identification code in the received signal the alarm device 11 inspects the lock/unlock state of the locking device 1. A mode setting part 15 places the device in an alarm mode when the mechanism is locked and resets the alarm mode when unlocked. An alarm control part 17 monitors abnormal vibrations applied to the motorcycle body and gives an alarm once the alarm mode is set. Consequently, the operation of the alarm device 11 can be controlled associatively with the locking or unlocking of the locking device 1. Thus, the operability is improved, what is called a partiality state is excluded to maintain high burglarproof property.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-theft system capable of preventing various objects to be locked, such as motorcycles and vehicles, from being stolen, and more particularly to a locking device which is detachably provided on the object to be locked. The present invention relates to an anti-theft system provided.

[0002]

2. Description of the Related Art A motorcycle as an example of an object to be locked is provided with a lock device such as a handle lock integrated with a main switch to prevent theft. However, the lock device fixed to the vehicle body may be mechanically broken by a driver or the like, and may be stolen. Therefore, in order to improve the anti-theft property, it has been proposed to further attach a separate lock device such as a chain lock, or to attach a warning device for monitoring an abnormality of a vehicle body.

The first prior art is disclosed in, for example,
JP-A-58249 discloses two types of lock devices, a mechanical lock device which is unlocked by an engine key and an electric lock device which is released by inputting a password. When the respective release signals are obtained, the operation of the ignition system is permitted.

As a second prior art, for example, Japanese Utility Model Laid-Open No.
For example, Japanese Patent Application Laid-Open No. 67224/1994 proposes a warning device that keeps a vehicle body in an immobilized state and monitors an abnormal situation. That is, this alerting device disables the operation of the ignition system when entering the alerting mode, detects abnormal vibration applied to the vehicle body by the vibration sensor, and sounds the alarm buzzer when the abnormal vibration is detected. It has become.

[0005]

In each of the prior arts described above, the anti-theft property is improved by providing a lock device or an alarm device. However, in order to further enhance security, the lock device and the alarm device are required. Preferably, both are provided. That is, it is preferable from the viewpoint of anti-theft property that the wheels and the like are locked by the lock device, and the vehicle body is monitored by operating the warning device.

However, when both the lock device and the security device are used, the operation of each device is complicated, and only one of them may be used regularly. For example,
Each time a motorcycle is parked or stopped or started, both the locking device and the warning device must be operated. Therefore, the operation is troublesome, and the risk of consciousness is likely to be lowered due to getting used to, so that only one of the devices is operated. As a result, a so-called one-handed drop is likely to occur, and a planned level of security cannot be secured.

Further, since the lock device and the security device are separate devices, and each device must be operated, it may be possible to operate only one device and forget to operate the other device. Therefore, for example, when the motorcycle is started without releasing the security device and without releasing the locking device that locks the wheels of the motorcycle, the wheels and the like may be damaged or the vehicle body may fall down. And so on.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described various problems, and an object of the present invention is to link a lock device and a security device so as to improve usability and maintain high antitheft property. Another object of the present invention is to provide an anti-theft system.

[0009]

In order to solve the above-mentioned problems, the anti-theft system according to the present invention notifies the security device of the locked state and the unlocked state of the locking device to the security device by radio signals, thereby enabling the two devices to be notified. Is linked.

That is, according to the first aspect of the present invention, there is provided an anti-theft system including a lock device detachably provided on an object to be locked and a security device for monitoring the object to be locked. The locking / unlocking state is notified to the security device by a radio signal, and the security device sets or cancels the security mode in conjunction with the locking / unlocking state.

Here, the "object to be locked" means an object to be locked by a lock device and to be protected from theft. Specifically, for example, a motorcycle, a car, a snowmobile, a motorboat, a warehouse , Garage, locker and the like. Locking objects are, for example, protection objects,
It can also be expressed as an anti-theft object. The “lock device detachably provided to the object to be locked” means a lock device that is attached to the object to be locked as a so-called retrofit. For example, a separate lock device such as a chain lock or a padlock that unlocks by matching four-digit numbers is removably attached to an object to be locked. “Locked / unlocked state” indicates a state of whether the lock device is locked or unlocked. "Wireless signal"
Means a signal transmitted without using a signal line, for example, an electromagnetic signal such as an RF signal, an optical signal such as an infrared signal,
An ultrasonic signal or the like can be used.

When the vehicle is parked and stopped, the user attaches the locking device to the locking object such as a motorcycle and locks the locking device, and the locking device is notified of the locking state to the security device by a radio signal. Thereby, the alerting device shifts to the alerting mode, and monitors whether or not the locking target has an abnormal state. on the other hand,
At the time of start, the user unlocks the lock device by performing a predetermined key operation. When the security device is notified of the unlocked state by a wireless signal, the security device cancels the security mode. Therefore, since the warning device operates in conjunction with the locking / unlocking state of the lock device, it is possible to prevent an incomplete state in which only the lock device is operated, and to prevent the lock device from being unlocked. It is possible to prevent a situation in which the locking target is operated from occurring.

According to a second aspect of the present invention, there is provided an anti-theft system comprising: a locking device detachably provided on the object to be locked; and a security device for monitoring the object to be locked.
The lock device generates a lock mechanism for locking the object to be locked, a locked / unlocked state detecting unit that detects a locked / unlocked state by the lock mechanism, and a state notification signal including the detected locked / unlocked state. Status notification signal generating means;
Transmitting means for transmitting the generated state notification signal by a wireless signal, comprising, the alert device,
Receiving means for receiving the state notification signal; monitoring means for monitoring the state of the object to be locked; and when notified by the state notification signal that the object is in the locked state, the mode shifts to the alert mode, and A mode setting means for canceling the alert mode when notified of the locked state, and whether an abnormal situation has occurred based on a signal from the monitoring means when the mode setting means has shifted to the alert mode. And a warning control means for monitoring whether or not there is an abnormal situation and outputting warning information when an abnormal situation occurs.

Here, the "status notification signal" is a signal for notifying the security device of the locking / unlocking status of the lock device. The “abnormal situation” means that the state of the lock target is not normal, specifically, a case where theft is likely to occur. “Warning information” means information for issuing a warning to a specific or unspecified person or a device, and specifically corresponds to a signal for sounding a warning buzzer, a warning lamp, or the like.

When the user attaches the locking device to the object to be locked and locks, the locked / unlocked state of the lock mechanism is detected by the locked / unlocked state detecting means. Then, the state notification signal generating means generates a state notification signal including the detected locked / unlocked state. This status notification signal is notified to the alerting device as a wireless signal by the transmission means. The status notification signal is
It is received by the receiving means of the alerting device. Then, when the locked state is notified, the mode setting means shifts to the alert mode. Accordingly, the alert control unit monitors whether or not an abnormal situation has occurred in the locking target based on the signal from the monitoring unit, and outputs the warning information when the abnormal situation is detected. On the other hand, when the user unlocks the lock device and the unlock status is notified to the alert device by the status notification signal,
The mode setting means cancels the alert mode. Therefore, since the mode of the security device can be switched in accordance with the operation of the lock device, it is possible to prevent the occurrence of an incomplete security state in which only the lock device is activated, and without unlocking the lock device. It is possible to prevent a situation in which the locking target is operated.

According to a third aspect of the present invention, the lock device further includes a storage unit for storing a preset transmission-side identification code, and the status notification signal generation unit stores the transmission-side identification code and The state notification signal is generated including the unlocked state, and the security device includes a storage unit that stores a preset reception side identification code, and a transmission side identification code included in the state notification signal. And an identification code determining means for determining whether or not the receiving side identification code is compatible with the receiving side identification code, and when it is determined that each of the identification codes is compatible, processing of the state notification signal is received. You can also.

Here, "compatible" means that the transmitting side identification code is recognized as a valid identification code. Typically, a case where the transmitting side identification code and the receiving side identification code match can be cited. However, the entirety of the identification code does not need to completely match, and a code that matches a preset encryption table can be determined to be a valid identification code. “Accepting the processing of the status notification signal” means setting and canceling the alert mode based on the locked / unlocked state included in the status notification signal.

An identification code is set in advance for both the lock device and the security device, and if both identification codes match,
The mode of the security device is set based on the locked / unlocked state of the lock device. This makes it possible to easily prevent the security device from interlocking with another lock device.

According to a fourth aspect of the present invention, the security device further includes an operating state detecting means for detecting an operating state of the object to be locked, and the security control means controls the security mode during the transition to the security mode. When the operation of the locking target is detected, an alarm may be issued.

For example, in the case of a motorcycle or an automobile as an object to be locked, the starting state of the engine or the preparation for starting can be detected by the operating state detecting means. In the present invention, since the security device operates in conjunction with the lock device, being in the security mode means that the lock target is locked by the lock device. Therefore, if the object to be locked is operated while being locked, damage to each part may be caused in some cases. Therefore, when the operation of the locking target is detected during the alert mode, an alarm is issued to draw the user's attention.

According to a fifth aspect of the present invention, in the lock mechanism, both ends of the wire member are fixed such that the wire member is detachably engaged with at least one end of the wire member. A body member, provided on the body member,
A cylinder lock for controlling the locking state of the wire member may be provided.

Here, the "wire member" means a member to be attached to an object to be locked, and specifically includes, for example, a wire, a chain, a rod, a bar, and the like.
The wire member can also be expressed as, for example, an engaging member for engaging with a locking target. `` A body member to which both ends of the wire member are fixed by detachably locking at least one end of the wire member ''
At least one of the two ends of the wire member fixed to the main body member is detachably locked. That is, when one end of the wire member is detachably fixed to the main body member, and the other end is fixed so as not to be detachable, both ends of the wire member are detachably attached to the main body member. And the case where it is fixed.

The user inserts the wire member between the spokes and the like, attaches both ends of the wire member to the main body member, and locks the cylinder lock. This allows
The wire member is engaged with the object to be locked, and locking is performed. When the cylinder lock is unlocked, the locking of at least one end of the wire member is released, so that the wire member can be pulled out from between the spokes and unlocked. Thereby, the lock device can be easily attached to the object to be locked.

According to a more specific aspect of the present invention, there is provided an anti-theft system comprising a locking device detachably provided on a vehicle, and a security device for monitoring the vehicle.
A locking mechanism for locking the vehicle; a locking / unlocking state detecting means for detecting a locking / unlocking state by the locking mechanism; a storage means for storing a preset transmission-side identification code; A status notification signal generating unit for generating a status notification signal including the locked / unlocked status and the transmission-side identification code, and a transmission unit for transmitting the generated status notification signal by a wireless signal. The warning device includes a receiving unit configured to receive the state notification signal, a vibration detecting unit configured to detect a vibration state of the vehicle, a storage unit configured to store a preset receiving-side identification code, The transmitting side identification code included in the notification signal is compared with the receiving side identification code, and if the respective identification codes match, the identification code determination for accepting the processing of the state notification signal is performed. Mode setting means for shifting to the alert mode when notified of the locked state by the state notification signal, and canceling the alert mode when notified of the unlocked state, When the mode is set to the alert mode by the mode setting means, the operation of the ignition system of the vehicle is prevented, and based on a signal from the vibration detecting means, it is monitored whether or not an abnormal situation has occurred in the vehicle. And a warning control means for activating an alarm when a situation occurs.

For example, when a lock device is attached to a vehicle as a wheel stopper or the like and locked, the locked state is notified to the security device as a radio signal together with the transmitting side identification code. The security device checks the transmission-side identification code against the reception-side identification code, and then shifts to the security mode. In the alert mode,
The operation of the ignition system is blocked, the immobilization process is performed, and the vibration detection means monitors an abnormal situation applied to the vehicle. When strong vibration is detected due to the movement of the vehicle or the destruction of the cylinder lock or the like, the alert control means activates the alarm. On the other hand, when the lock device is unlocked, the alert mode of the alert device is also released in conjunction with the unlocking. This allows
The locking device and the security device can be linked with each other, so that high usability can be maintained while improving usability.

Are provided. These cylinder switch 3, each bar switch 4, 5 correspond to "locking / unlocking state detecting means". The cylinder switch 3 outputs an off signal when the cylinder lock 32 is in the locked state, and outputs an on signal when the cylinder lock 32 is in the unlocked state. Each of the bar switches 4 and 5 is connected to a wire member 36.
Outputs an ON signal when the end of the wire member 3 is inserted, and the wire member 3
When the end of 6 is pulled out, an off signal is output.

The wire member 36 is composed of, for example, a chain or a rod, and has both ends provided with ends 36A and 36B inserted into the slots 33 and 34 and locked. The user inserts the wire member 36 into a gap (engagement point) 38 such as between spokes of the motorcycle, and inserts each end 36A, 36B into each slot 33, 34 of the main body member 31. Thereby, each end 36A, 3
6B is latched by a claw member or the like. Next, when the user inserts the engine key 37 into the cylinder lock 32 and performs a locking operation, each end 36A, 36B of the wire member 36 is operated.
Is fixed to the main body member 32.

Referring again to FIG. In the ID memory 6 as a “storage unit”, a transmission-side identification code is stored in advance. A state notification signal generation unit (hereinafter, abbreviated as “signal generation unit”) 7 as “state notification signal generation means” monitors a state of each of the switches 3, 4, and 5, and generates a predetermined state notification signal. It is. That is, when the lock state of the lock mechanism 2 is detected by the switches 3, 4, and 5, the signal generation unit 7 reads the transmission-side identification code from the ID memory 6, and transmits the transmission-side identification code and the lock code indicating the lock state. And generates a status notification signal. On the other hand, when the unlocked state is detected, a state notification signal is generated from the transmitting side identification code and the unlocked code indicating the unlocked state. The transmitting unit 8 as a “transmitting unit” transmits the state notification signal input from the signal generating unit 7 to the security device 11 as a wireless signal.

The warning device 11 is attached to a motorcycle, for example, as a so-called retrofit, and monitors the state of the vehicle body. The alerting device 11 includes a receiving unit 12, an ID memory 13, an ID
Determination unit 14, mode setting unit 15, vibration sensor 16
, An alert control unit 17 and a horn 18.

The receiving section 12 as “receiving means” is for receiving a radio signal transmitted from the lock device 1. In the ID memory 13 as “storage means”, a receiving-side identification code is stored in advance. The ID determination unit 14 as “identification code determination means” determines whether the transmission-side identification code included in the status notification signal from the lock device 1 matches the reception-side identification code stored in the ID memory 13. Then, the determination result is input to the mode setting unit 15.

The mode setting unit 15 as the "mode setting means" sets or releases the alert mode based on the locked / unlocked state of the lock device 1 when the determination result of the ID determination unit 14 is affirmative. It is. That is, the mode setting unit 15 sets the alert mode when the lock code is included in the state notification signal, and releases the alert mode when the unlock code is included in the state notification signal. .

The vibration sensor 16 as "monitoring means" or "vibration detecting means" detects and outputs vibration applied to the vehicle body. The alert control unit 17 as “alert control means” determines whether or not an abnormal situation has occurred in the vehicle body based on the detection signal of the vibration sensor 16, and when it is determined that the abnormal situation has occurred, the “alarm unit” The horn 18 is caused to sound by outputting an alarm signal to the horn 18 as "." Note that the horn 18 is not provided in the alerting device 11, and a horn mounted on the vehicle body can be used.

The alert control unit 17 controls the operation of a switch 19 provided between the ignition switch 20 and the ignition device 21. That is, while the warning mode is set, the contact of the switch 19 is opened and the power supply path to the ignition device 21 is cut off, so that even if the ignition switch 20 is broken or directly connected to the ignition device 21, The operation of the vehicle is stopped to immobilize the vehicle body. An alert mode cancel switch 22 for manually canceling the alert mode is provided in parallel with the switch 19.

Next, the operation of the present embodiment will be described with reference to FIGS. FIG. 3 is a flowchart showing the lock device side processing executed on the lock device 1 side.

First, in step (hereinafter abbreviated as “S”) 1, it is determined whether or not each of the bar switches 4 and 5 is on, that is, each end 36 A and 36 B of the wire member 36 is It is determined whether or not it has been inserted. If it is determined that the bar switches 4 and 5 are on,
It is determined whether or not the cylinder switch 3 is in an off state, that is, whether or not the cylinder switch 3 is in a locked state (S2).

If it is determined that the cylinder switch 3 is in the off state, it means that the wheels are locked by the lock mechanism 2, so the transmitting side identification code is read from the ID memory 6 (S3), and the transmitting side identification code is read. A state notification signal is generated by adding a lock code indicating the lock state to the code (S
4). This status notification signal is transmitted from the transmitting unit 8 to the alerting device 11.
(S5).

If "NO" is determined in S2,
In this case, the bar switches 4 and 5 are on, but the cylinder switch 3 is not off. In other words, "NO" is determined in S2 from the time when the ends 36A, 36B of the wire member 36 are inserted into the slots 33, 34 to the time when the cylinder lock 32 is rotated. Therefore, if “NO” is determined in S2, it is monitored whether or not the cylinder switch 3 has changed from the on state to the off state (S6). If the cylinder switch 3 has changed to the off state, It is confirmed whether or not the bar switches 4 and 5 are kept on (S7), and the process returns to S3.

On the other hand, when performing the unlocking operation, since the cylinder lock 32 is unlocked and the ends 36A, 36B of the wire member 36 are pulled out from the slots 33, 34, the bar switches 4, 5 are turned off. State. Therefore, the S1
Is determined to be "NO", and the routine goes to S8. In S8, it is monitored whether or not the cylinder switch 3 has changed from the off state to the on state, that is, whether or not the cylinder lock 32 has been unlocked. When the cylinder lock 32 is unlocked, the ID memory 6
(S9), and adds the unlock code to the identification code to generate a status notification signal (S1).
0). This state notification signal is transmitted to the security device 11 via the transmission unit 8 (S11).

As described above, when the lock mechanism 2 is locked or unlocked, the lock device 1 generates a state notification signal corresponding to the locked / unlocked state and transmits it to the security device 11.

Next, FIG. 4 is a flowchart showing the alerting device-side processing executed on the alerting device 11 side. First,
In S21, it is monitored whether a status notification signal from the lock device 1 has been received. If the receiving unit 12 has not received the signal, the process proceeds to a warning process described later with reference to FIG. 5 (S
22).

When the status notification signal is received, the transmitting side identification code and ID memory 1 included in the status notification signal are received.
Then, it is determined whether or not the receiving side identification code stored in No. 3 matches (S23). If it is determined that the two identification codes do not match, it means that a status notification signal has been received from another lock device or the like.
Return to 1. When it is determined that the two identification codes match each other, it means that the status notification signal from the lock device 1 corresponding to the security device 11 has been received. Is notified (S24).

If it is determined in S24 that the vehicle is in the locked state, the security controller 17 is set to the security mode (S24).
25) Then, power is supplied to the vibration sensor 16 to monitor vibration applied to the vehicle body (S26), and immobilization processing is performed by opening the contact of the switch 19 (S27). On the other hand, if it is determined in S24 that it is not in the locked state but in the unlocked state, the alert mode is released (S28), the contact of the switch 19 is closed to release the immobilization processing (S29), and the horn 18 is released. Turn off the alarm signal output to (S3
0) Stop the horn 18 from sounding.

As described above, the security device 11 sets and releases the security mode (armed) in conjunction with the locked / unlocked state of the lock device 1 indicated by the status notification signal.

Next, FIG. 5 is a flowchart showing the alert processing shown as S22 in FIG.

First, in S41, it is determined whether or not the alert mode has been set. If the alert mode has not been set, the process ends. If the alarm mode is set, it is determined whether or not the alarm signal is on (S42).

If no alarm signal is output,
It is determined whether or not abnormal vibration is detected (S43). For example, when a third party attempts to move the vehicle body or break the steering lock, the detection signal of the vibration sensor 16 exceeds a predetermined reference value, and thus it is known that abnormal vibration has occurred as an abnormal situation. be able to. It is preferable that the limit of whether or not the vibration is abnormal or the detection sensitivity of the vibration sensor 16 can be appropriately adjusted.

When abnormal vibration is detected, since an abnormal situation has occurred, an alarm signal is output to sound the horn 18 (S44), and a timer for defining the sounding period is started (S45). ).

Then, again through S21 in FIG. 4, FIG.
Returning to S41, it is determined in S42 whether an alarm signal has been output. If the alarm signal has been output, it is determined whether a predetermined time has elapsed since the timer was started in S45 (S4).
6). Until the predetermined time elapses and the time is up, S4
Steps S1, S42 and S46 are repeated. When the predetermined time has elapsed, the output of the alarm signal is stopped (S47).

As described above, in the alert processing, when the alert mode is set, the occurrence of abnormal vibration is monitored based on the detection signal from the vibration sensor 16, and when the abnormal vibration occurs, it is kept for a predetermined time. The horn 18 is sounded to call attention to the surroundings.

According to the present embodiment configured as described above, the following effects can be obtained.

First, by notifying the security device 11 of the locking / unlocking state of the locking device 1 as a radio signal, the setting and release of the security mode of the security device 11 are linked with the locking / unlocking state of the locking device 1. There is no need to separately operate the security device 11, and the lock device 1 and the security device 11 can maintain high antitheft properties. That is, the alerting device 11
Is linked to the lock device 1, so that the security device 11 is not forgotten to be set, and it is possible to secure high antitheft property and safety while improving usability.

Second, since the security device 11 is linked to the locking / unlocking state of the locking device 1, the user needs to lock and unlock the locking device 1 in order to release the security mode of the security device 11. . Therefore, the situation in which the motorcycle is started without forgetting to unlock the lock device 1 does not occur, and the safety is improved.

Third, since the locking / unlocking state of the lock device 1 is notified by a radio signal, there is no need to attach a signal line or the like, and the usability is improved.

Fourth, since the security device 11 sets and releases the security mode after collating the identification code from the lock device 1, the security device 11 does not operate due to a signal from another lock device, and has a high antitheft property. Reliability can be improved.

Fifth, the lock mechanism 1 includes the wire member 36
Of both ends 36A, 36B of the main body member 31
Since the locking state is controlled by the cylinder lock 32, it can be easily attached to the wheels of a motorcycle, and the usability is improved.

S52 has been added.

That is, if it is determined in S41 that the alert mode has been set, it is monitored whether or not the ignition switch 20 has been turned on (S51). If the ignition switch 20 has been turned on, ,
For example, the horn 18 is sounded by outputting an alarm signal for only 0.1 second (S52).

On the other hand, if it is determined in S51 that the ignition switch 20 is not in the ON state,
It skips S52 and moves to S42, and determines whether or not the alarm signal is output.

In the present embodiment configured as described above,
The same operation as in the first embodiment can be obtained. In addition to this, in the present embodiment, the state of the ignition switch 20 is monitored, and if the ignition switch 20 is operated during the alert mode, a short-time alarm is issued.
