As a result, the siren operation time can be set to 3 to 60
Can be set to any time up to seconds.

Sleep Function Reduces current consumption when the system is used continuously for 24 hours or more. As shown in FIG.
Within 4 hours, alarm function, immobilizer function,
Remote control operation and indicator lamp display are possible, but after 24 hours, a sleep state is established and the alarm function and immobilizer function can be operated, but the remote control operation and indicator lamp display cannot be performed.

Thus, when the system is used for a long time, the load on the battery of the motorcycle is reduced.

Next, the configuration and the like of the antitheft device main body 1 will be described together with its operation.

(1) Set the system.

When the main switch 8 of the motorcycle is turned off, the system is automatically set. Manual setting by the remote controller 6 is also possible.

Automatic setting As shown in FIG. 8, the main switch 8 of the motorcycle is turned off.
If it is set to FF, the automatic setting means 1 of the antitheft device body 1
2, the indicator lamp 5 is turned on for 60 seconds. This is a preparation state, after which the indicator lamp 5 blinks about once every two seconds. The system is now in the set state.

As shown in FIG. 9, when the main switch 8 is turned off and the first push button 6b of the remote controller 6 is pressed, the indicator lamp 5 is turned on by the antitheft device main body 1 for four seconds. After blinking twice, it changes to blinking once every 2 seconds. The system is now in the set state. In this case, unlike the automatic setting, the setting can be performed without waiting for 60 seconds.

(2) Release the system.

When the main switch 8 of the motorcycle is turned off, the system is automatically set. Therefore, it is necessary to release the system before riding the motorcycle.

The system release is performed as follows (see FIG. 10).

When the first push button 6b of the remote controller 6 is pressed, the indicator lamp 5
Changes from flashing to lit. If there is a history of the siren 4 sounding while the system is operating, it blinks twice before changing from blinking to lighting.

When the main switch 8 of the motorcycle is turned on, the indicator lamp 5 turns off. In this state, you can start the engine.

(3) Disable automatic setting of the system.

In some cases, such as when refueling at a gas station or when servicing a motorcycle, there is a case where it is not desired to set the system automatically.

In such a case, it is possible to prevent the automatic setting by performing the following operation (see FIG. 11).

When the second push button 6 c of the remote controller 6 is pressed while the main switch 8 is ON, the automatic set inactivation command signal is transmitted from the remote controller 6 to the anti-theft device main body 1.
And the signal from the remote control receiving means 13 is input to the control means 11, and the automatic setting means 12 is disabled by the control means 11, and the indicator lamp 5 flashes twice. Turns off afterwards. In this state, even if the main switch 8 is turned off, the automatic setting of the alarm (system) cannot be performed.

Thus, when the gasoline is supplied, the siren 4 does not accidentally sound.

(4) Releasing the sleep function While the sleep function is operating, the system cannot be released by the remote controller 6 as described above. However, since the alarm function and the immobilizer function are in operation, before the passenger gets on the vehicle, Then, the system is released by the following operation (see FIG. 12).

A switch circuit 14 for turning on / off the power supply to the receiving circuit constituting the remote control receiving means 13 is provided. The switch circuit 14 is set to the OFF state, that is, the sleep function is activated. When the main switch 8 is turned on from this state, the power supply to the receiving circuit constituting the remote control receiving means 13 is switched from the OFF state to the ON state by the switch circuit 14, and the indicator lamp flashes once every two seconds. As a result, the sleep function is released, and the system is set. In this case, the operation of the main switch 8 without releasing the system is controlled by the control means 11 so that the siren 4 does not sound.

By doing so, the sleep function
Power consumption can be reduced and the main switch 8 is turned on.
By doing so, even if the sleep function is canceled, the siren 4 does not sound carelessly.

Thereafter, the first push button 6b of the remote controller 6
Alternatively, when the second push button 6c is pressed, the indicator lamp 5 turns off. Thus, the set state of the system is released, and the engine can be started in this state.

(5) The siren 4 is stopped.

The siren 4 can be stopped by pressing the first push button 6b or the second push button 6c of the remote controller 6. When the first push button 6b is pressed, the system is released after the siren 4 stops, and 1
Will be reset after a minute.

(6) The operating time of the siren 4 is changed.

The operating time of the siren 4, that is, the time during which an alarm is generated from the siren 4, is determined by the main body 1 of the anti-theft device.
Is set by the alarm generation time setting means 16, and here, for example, is set to 15 seconds in an initial state.
It can be changed by performing the following operations.
The operation time (alarm generation time) of the siren 4 is 3 to 6
Any time up to 0 seconds can be set.

As shown in FIG. 13, the main switch 8
To OFF.

The connector connected to the battery power supply is once disconnected and reconnected. Thereby, the fact that the battery power is turned on is detected by the power-on detecting means 15 of the anti-theft device main body 1, and the indicator lamp 5 is turned on.

When the main switch 8 is turned on, the siren 4 sounds, and the main switch 8 is turned off after a lapse of a desired time. Then, the siren 4 stops.

Thus, the time from when the main switch 8 is turned on to when the main switch 8 is turned off is detected by the time detecting means 17 after detecting that the battery power supply 7 is turned on based on the signal from the power-on detecting means 15. And the control unit 11 rewrites the set time of the alarm generation time setting means 16 to the detected time.

Accordingly, the period from when the main switch 8 is turned on to when it is turned off (time when the siren 4 is sounding) is the set time.

When the setting is to be reset, the setting can be made by performing the above operation again.

As described above, the set time can be changed by turning on / off the main switch 8 by disconnecting / connecting the connector, so that it is necessary to provide a knob or a power ON / OFF switch on the anti-theft device main body 1. There is no need to provide a waterproof structure.

On the other hand, each button 6 of the remote control main body 6a
Since the buttons b and 6c are arranged on the arrangement surface portions 6e having different heights due to the steps, it can be tactilely determined which of the buttons 6b and 6c, and the operability is good. The buttons 6b and 6c are relatively large and easy to push, and the corners of the remote control main body 6a are rounded, so that the buttons 6b and 6c are easy to fit in the hand.

Further, since the indicator lamp 5 is attached to the upper surface of the fuel tank 10 which is a substantially horizontal surface with the double-sided tape 5c, it is not necessary to arrange a stay or the like on the vehicle body side, and the number of parts can be reduced. In addition, the workability of arrangement can be improved. Further, the sticking position may be on the upper surface of the handle crown, around the meter, near other indicators, or the like.
