[Problems to be solved by the invention]

 Since the conventional car burglar alarm system was configured as described above, the following problems existed. That is, in the case of the first and second conventional examples, there are times when the driver forgets to turn on the switch under various conditions of the driver, and if so, the alarm device is useless at all. Was. Further, in the case of the third conventional example, if the remote controller which is a dedicated key is forgotten in the vehicle, there is a possibility that the vehicle cannot be smoothly boarded. Also, in each of the above-mentioned conventional examples, a remote controller as a dedicated key must be provided, and it is necessary to always carry the remote controller, and the owner of the car always feels troublesome. In addition, since it is necessary to always have a remote controller that is a dedicated key, it is necessary to carry a start key, which may cause loss or damage. Further, as described above, in an extreme case, the burglar alarm device may be detached from the vehicle and may not be used due to the inconvenience of holding the dedicated key.

[0004] The present invention has been made to solve the above-described problems. In particular, by directly setting the ignition part, a start key is provided after a predetermined time has elapsed after the door is opened or closed or vibrated. An object of the present invention is to provide an automobile burglar alarm device that generates an alarm when a vehicle is not inserted, and that enters a standby state after a predetermined time has elapsed after a start key is removed.

[0005]

[Means for Solving the Problems]

 An automobile burglar alarm device according to the present invention includes an input discriminator to which a door open / close signal from a door open / close sensor and a vibration presence signal from a vibration sensor are inputted, and a first alarm signal from the input discriminator, which is set in advance by a second An alarm signal delay unit for inputting the alarm signal to the alarm signal standby / release unit with a delay of one delay time and a start key absence signal from a start key sensor for detecting the presence of the start key are preset. A signal delay unit without a start key for inputting to the alarm signal standby / release unit after being delayed by the second delay time, and an alarm unit connected to the alarm signal standby / release unit for generating a sound or emitting light is operated. The start key sensor does not detect the start key presence signal indicating the presence state of the start key within the first delay time T1 after the first alarm signal is generated. The alarm section is activated, and a start key absence signal, in which the start key sensor detects the absence of the start key, is input to a start key absence signal delay section, and after the lapse of the second delay time T2, the second alarm signal is output. The alarm section is activated when an alarm occurs, and the first and second delay times can be variably set.

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the vehicle burglar alarm system according to the present invention will be described with reference to the drawings. The same or equivalent parts as those in the conventional example will be described using the same reference numerals. In FIG. 1, reference numeral 1 denotes a well-known door opening / closing sensor provided on a door of a vehicle. A door opening / closing signal 1 a from the door opening / closing sensor 1 is input to an input determining section 3. A vibration sensor 2 for detecting an external shock or vibration applied to the door or body is attached to a required place of the car door or body, and a vibration signal 2a from the vibration sensor 2 is provided. Is input to the input determination unit 3.

When the above-mentioned door opening / closing signal 1 a or vibration presence signal 2 a is inputted from the input discriminating section 3, a first alarm signal 3 a is outputted and inputted to the alarm delay section 4. ing. The alarm signal delay unit 4 has a delay characteristic having a first delay time T1 of 15 seconds set in advance by the first setting unit 4A, and the first alarm signal 3a has only the first delay time T1. The signal is delayed and input to the alarm signal standby / release unit 7 as the second alarm signal 4a. The time width of the first delay time T1 is configured to be variably set by a switch of the first setting unit 4A or a touch sensor switch of the display unit.

In FIG. 1, reference numeral 5 denotes a start key sensor provided on an ignition switch (not shown) of the vehicle, and a start key (not shown) is inserted into the ignition switch. It is configured to be able to detect whether the vehicle has been pulled out or pulled out (in fact, a sensor is installed on a commercial vehicle as is well known, and a warning sound is generated if the driver forgets to remove the start key and opens the door). When the start key is removed, the start key absence signal 5a is output. When the start key is inserted, the start key presence signal 5b is output. There.

The start key absence signal 5a is input to a start key absence signal delay section 6 having a preset second delay time T2 of 30 seconds, and the second delay time T2 is set to a second setting section. 6A is configured so that the time width can be freely set. The start key presence signal 5b is configured to be directly input to the alarm signal standby / cancellation unit 7, and the start key absence signal 5a is delayed by the second delay time T2 of the start key absence signal delay unit 6. The signal 5aA without the delay start key is input to the alarm signal standby / release unit 7.

A third alarm signal 7 a output from the alarm signal standby / release unit 7 is input to an alarm drive unit 8 to drive a well-known alarm unit 9 capable of performing operations such as sound generation or light emission. If the horn provided in the vehicle is actually configured as the alarm unit 9, the alarm unit 9 can be easily configured and a large alarm effect can be obtained, but another sound or light emission can be used.

Next, the operation will be described. First, insert the start key into the ignition switch of the car, start the engine, run the car, remove the start key from the ignition switch, open the door, lock the door, the driver locks the door, When the driver leaves, the vehicle is parked. In the above-described state, if a suspicious person who does not have a start key forcibly opens the door of the car or applies vibration to the vehicle body, the door open / close signal 1a and / or the vibration presence signal 2a are input to the input determination unit 3, The first alarm signal 3a is input to the alarm signal delay unit 4 and is input to the alarm signal standby / release unit 7 as the second alarm signal 4a 15 seconds after the first delay time T1. In the alarm signal standby / release unit 7, if the start key sensor 5 does not input the start key presence signal 5b from the start key sensor 5 to the alarm signal standby / release unit 7 within the period of the first delay time T1, the third alarm signal 7a Is input to the alarm drive unit 8 to drive the alarm unit 9 to prevent theft.

In the above-described case, the first alarm signal 3a is similarly input to the alarm signal delay unit 4 when the owner of the vehicle opens the door and gets on the vehicle, but the first delay time T1 If the start key is inserted within 15 seconds to start the engine, the third alarm signal 7a is not generated and normal operation can be performed.

When a second delay time T2 of 30 seconds elapses after the driver removes the start key from the ignition switch, the alarm signal standby / cancellation unit 7 enters a standby state. When opening / closing or vibration occurs, the first alarm signal 3a is generated, and after the first delay time T1, the second alarm signal 4a is generated as described above, and the alarm unit 9 is driven. In the case described above, if the driver inserts the start key into the ignition switch within 30 seconds after locking the door, the operation of the alarm unit 9 is prevented, and normal operation can be performed.
