Изобретение относитс к устройствам охранной сигнализации и может примен тьс дл охраны автомобилей.The invention relates to security alarm devices and can be used for car security.

Известны устройства, которые используютс дл охраны автомобилей. Одно из них содержит конденсатор, к обкладкам которого подключены группы контактов на переключение , и сигнальную кнопку. Это известное устройство не обеспечивает удобства обслул ивани автомобил , так как при входе и выходе водител дает ложный сигнал, что неприемлемо на улицах и открытых сто нках. Наиболее близким техническим решением к изобретению вл етс устройство дл охраны автомобил , содержащее реле времени, соединенное с сигнализатором, выключатель, соединенный с источником питани , и контактный датчик, а также врем задающую цепь, обеспечивающую возможность выхода водител из автомобил в течение определенного времени без сигнала тревоги. Однако ограничение времени выхода водител из автомобил снижает надежность устройства.There are known devices that are used to protect cars. One of them contains a capacitor, to the plates of which groups of contacts are connected for switching, and a signal button. This well-known device does not provide convenience for servicing the car, as the driver gives a false signal at the entrance and exit, which is unacceptable on the streets and open parking lots. The closest technical solution to the invention is a car security device containing a time relay connected to an alarm device, a switch connected to a power source, and a contact sensor, as well as a driver circuit allowing the driver to exit the car for a certain time without a signal anxiety However, the time limit for the driver to exit the car reduces the reliability of the device.

Целью изобретени вл етс исключение ограничени времени выхода водител из автомобил и, следовательно, повышение надежности . В описываемом устройстве это достигаетс тем, что в него введен счетчик, щина The aim of the invention is to eliminate the limitation of the driver’s exit time from the car and, consequently, increase the reliability. In the described device, this is achieved by the fact that a counter is inserted into it,

питани которого соединена с выключателем непосредственно, счетный вход - через контактный датчик, а выход счетчика подключен ко входу реле времени.the power supply of which is connected to the switch directly, the counting input is through a contact sensor, and the counter output is connected to the time relay input.

На чертеже представлена блок-схема описываемого устройства.The drawing shows the block diagram of the described device.

Выключатель 1 подключен к источнику питани 2 и через контактный датчик 3, установленный , например, на двери, соединен с лампой 4 освещени салона и со счетным входом счетчика 5, выход которого подключен к реле времени 6, соединенному с сигнализатором 7. Выключатель 1 подключен также к шине питани счетчика 5 и к цепи зажигани .Switch 1 is connected to power supply 2 and through a contact sensor 3 mounted, for example, on a door, connected to interior lighting lamp 4 and to the counting input of counter 5, the output of which is connected to time relay 6 connected to alarm indicator 7. Switch 1 is also connected to the power bus of the counter 5 and to the ignition circuit.

Claims

The driver before exiting the car using switch 1 supplies power to the counter 5, at the same time the engine ignition circuit is interrupted and the counter 5 is automatically set to the position "O." After leaving the car, the driver opens and closes the door, which triggers the contact sensor 3, and the counter 5 is switched to the position "1, which is maintained for an arbitrarily long time. When the driver returns (or attempts to hurt), the second door opening and moves the counter to position 2, and this position is maintained, regardless of the further operation of the contact sensor 3, until the power supply is turned off

2. In this position, counting 5 activates the time relay 6. After several (8-10) seconds of the time relay 6, the analyzer 7, informing you of the irradiation of the vehicle to the outside, will come to the CIS. A shutter speed of a few seconds enables the driver, when entering the car, to turn off the alarm device 7 with the help of a notary switch 1, without causing false alarms. Claims An automobile alarm device comprising a time relay connected to an alarm device, a switch connected to a power source, and a contact sensor, characterized in that, in order to increase the reliability of the device, a counter is inserted in it, the power bus of which is connected to the switch , the counting input is via a contact sensor, and the output of the counter is connected to the input of the time relay.
