DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0015] according to Figure 1 、 Figure 2 As shown, a passenger car alarm control device includes: a positive power supply electrode 11, a fuse 12, and a flash alarm controller, wherein the positive power supply electrode 11 is connected to the upper end of the fuse 12, the lower end of the fuse 12 is connected to pin 2 of the flash alarm controller, pin 3 of the flash alarm controller is connected to the 12V+ signal input of the door opening signal, pin 6 of the flash alarm controller is connected to the 12V+ signal input of the reverse signal, pin 5 of the flash alarm controller is connected to the negative power supply electrode 17, pin 1 of the flash alarm controller is connected to an alarm 18 without a flash function, and pin 4 of the flash alarm controller is connected to an alarm 21 with a built-in flash function;

[0016] When working, pin 4 of the flash alarm controller is connected to an alarm light with a built-in flash function, while pin 1 of the flash alarm controller is connected to an alarm light without a flash function. The two modes correspond to the needs of these two different alarm lights. Pin 1 of the flash alarm controller outputs a flash output, while pin 4 of the flash alarm controller outputs a constant light output. During use, this device can adapt to the needs of different alarm lights, thereby improving the scope of application of this device.

[0017] Specifically, the flash alarm controller includes: a diode A14, a diode B15, and a flash relay. The left side of the diode A14 is connected to pin 3 of the flash alarm controller, the diode B15 is connected to pin 6 of the flash alarm controller, and the right sides of the diode A14 and the diode B15 are connected to the flash relay.

[0018] Furthermore, the flash relay includes: a pulse controller 13, a double-contact linkage relay 16, a relay contact A20 and a relay contact B19. The upper end of the pulse controller 13 is connected to pin 2 of the flash alarm controller, the upper part of the pulse controller 13 is connected to the relay contact B19, and the other end of the relay contact B19 is connected to pin 4 of the flash alarm controller. The lower end of the pulse controller 13 is connected to the upper part of the double-contact linkage relay 16, the lower part of the pulse controller 13 is connected to the relay contact A20, and the other end of the relay contact A20 is connected to pin 1 of the flash alarm controller.

[0019] Furthermore, the left side of the double-contact linkage relay 16 is connected to the right ends of the diode A14 and the diode B15, and the lower end of the double-contact linkage relay 16 is connected to pin 5 of the flash alarm controller;

[0020] During operation, when the vehicle power switch is turned on, the positive power supply 11 and the negative power supply 17 are input from pins 2 and 5 of the flash alarm controller respectively. At this time, if the flash alarm controller receives a 12V+ signal input from pin 3 or pin 6, the flash relay is triggered to work, so that relay contact A20 and relay contact B19 are attracted, and the power is connected. At this time, pin 4 of the flash alarm controller outputs a continuous positive power supply, and pin 1 outputs a fixed number of intermittent power supplies per minute (such as 75±5 times per minute) according to the frequency set by the pulse controller 13; at this time, pin 4 can be connected to an alarm device with a built-in flash function, and the alarm device emits an audible and visual alarm according to its own set frequency;

[0021] Pin 1 can be connected to an ordinary alarm device. The alarm device pulse controller 11 outputs a frequency to emit an audible and visual alarm. The role of the diode A14 and diode B15 of pins 3 and 6 in the flash alarm controller is to prevent the signals of pins 3 and 6 from flowing back to each other, preventing the door opening and reversing signals from being connected in series incorrectly.

[0022] In order to ensure the stability of the device's working state, some simple voltage or current stabilization circuits can be appropriately added inside the device.
