Detailed ways

As shown in FIG. 1 , the emergency alarm system for children in the vehicle in the locked state of the passenger vehicle includes a touch switch 1 arranged in the vehicle; the surface of the touch switch is provided with a touch induction mark for young children The touch switch is connected with the control unit 3; the control unit can control the car audio system, the high beam 4 of the car, the double flashing warning light 5 and the horn 6; When the switch is triggered, the control unit flashes the high beam and double flashing warning lights, and makes the horn sound.

If the original light, signal control unit and ECU unit of the car are still powered after the car is safely locked, the control unit will follow the ECU unit of the car, and the ECU unit of the car will become the control unit of the emergency alarm system; if the car is safe When the ECU unit of the car is powered off after locking, the control unit adopts the control unit of the distress alarm system to output the control signal, and uses the battery as the power source.

An alarm program is pre-written in the control unit of the distress call alarm system; the alarm program outputs a control signal according to the trigger of the touch switch and the state of the car to control the high beam and the double flashing alarm light of the car to flash continuously, and simultaneously control the rapidity of the car horn. tweet.

A reminder program is pre-written in the control unit of the emergency call alarm system; after the car is safely locked, the control unit flashes and lights up the guidance sign according to the settings of the reminder program; at the same time, it controls the in-car audio system to start, and the control unit presses the reminder program. set to output a voice signal prompting the child to touch and press the inductive sign to the sound system, and play it repeatedly at a preset frequency.

When the touch switch is triggered, the control unit drives the high beam, the double flashing warning light, and the horn to send out an alarm signal for more than 30 minutes, and after 30 minutes, it switches to an alarm every two minutes to save electricity .

After the touch switch is triggered, if the car restarts, the control unit stops the alarm and stops the voice reminder.

The touch-inducing sign is a picture decorated with a light-emitting sign 2; the diameter of the touch surface of the touch switch is greater than 10 cm.

The touch switch is connected to the ECU related to the light, signal and sound of the car through the dark wire in the compartment.

Example:

The alarm system control unit is in a standby state after power supply, and maintains communication with the car safety control unit or the car main microprocessor control unit to monitor the state of the car.

When the car is safely locked, the system enters the on-duty state and sends out a flashing signal of the light that induces the sign; it maintains communication with the in-car audio system and sends out a voice reminder signal.

When there are children or pets in the car, if the touch switch is pressed unintentionally, or is pressed consciously because the child is instructed, prompted or induced, the control unit detects multiple touches of the distress alarm system through real-time keyboard scanning. After any switch in the switch is in the low level state, it enters the alarm action program, outputs each alarm signal, or directly outputs the voltage or current that drives the action of the high beam, alarm light, and horn (in this embodiment, the direct drive method is used).

In order to attract the attention of nearby people and save the power consumption of the battery, the alarm action is carried out in the following way: the alarm signal lasts for at least 30 minutes at the beginning, then turns to the alarm for 2 minutes, stops for 2 minutes, and repeats the cycle.

After the control unit detects that the car is restarted, it stops the alarm and stops the voice reminder, and returns to the initial state.

In this example, the touch switch is highly sensitive and is hidden under the artwork.

The picture decoration in this example adopts children's color pictures that have the following characteristics as much as possible: children's favorite patterns or object images or cartoon characters; patterns containing water, fruits, drinks; patterns containing children's favorite snacks; Patterns of open windows; patterns containing dewy ice cubes, ice cream; patterns containing red sun, etc.

In this example, the figurine has hidden lights, and the figurine is illuminated by the shining lights.

Touch switches and graphic decoration kits are distributed in many places such as the backs of the front seats and the trunk. If necessary, the periphery of the passenger seat can also be considered. Place it in a place where children can easily reach it.

In this example, the control of decorative lights, high beams, warning lights, and horns can also be partially or completely controlled by the control unit outputting control signals. After passing through their respective control circuits, the power supply supplies power to each controlled object to operate. The horn acts, and the circuit unit that controls the horn can also provide a specific horn sound type to give an alarm.
