Multi-function vehicle fault sign

This creation is a multi-function vehicle fault sign using electronic devices. Its application technology includes single-chip control technology, wireless transmission technology, dump detection technology, light sensing technology and ultrasonic ranging technology, mainly for faulty vehicle drivers. And other vehicles get double warnings to achieve all-round security.

We often see in the TV news that the driver is often knocked down by the vehicle fault sign, causing the driver to be seriously injured or even killed by the rear car. Therefore, the previous vehicle fault sign is to use the reflector to remind the same lane. When the car is diverted, it can only be a one-way reminder. When the vehicle fault sign is knocked down by a car or blown down by a strong wind, the driver is difficult to know. At this time, the driver's life safety will be greatly threatened. If it is not discovered immediately, it will cause an accident. In addition, when the traditional fault sign encounters rain, fog or poor visibility, the warning effect will be greatly reduced.

It is also possible for the driver to leave the vehicle fault sign on the scene. If the driver forgets to buy it, the life safety will be red.

Since the vehicle fault sign must be placed on the road surface 30 to 100 meters behind the vehicle when the vehicle is faulty on the general road, it is assumed that the rear vehicle speed is 50 kilometers per hour. When the vehicle fault sign is knocked down, the driver can escape from the scene. The time is about 6~8 seconds.

Therefore, the multi-function vehicle fault sign is mainly to make the faulty vehicle driver and others The vehicle is given a double warning. In order to distinguish it from the vehicle fault sign currently used by the general public, the multi-function vehicle fault flag is divided into two parts, as shown in Figure 1, including the vehicle fault flag (10) and the wireless alarm. (20). The vehicle fault flag (10) includes: the vehicle fault flag includes: a single chip controller (11), a light sensor (12), an LED flasher (13), a wireless transmitter (14), and an ultrasonic range finder ( 15), a dump detector (16), wherein the single chip controller (10) controls the function of the photo sensor (12) and the ultrasonic range finder (15) and the signal transmission of the wireless transmitter (14) . The dump detector (16) detects whether the vehicle fault sign has been knocked down by the same lane or is blown down by strong wind. If the vehicle comes to the car and knocks the vehicle fault sign (10), the vehicle fault flag (10) will The control wireless transmitter (14) immediately stops transmitting the signal, and the wireless alarm (20) on the driver immediately sounds an alarm due to the failure to receive the signal of the vehicle failure flag (10), prompting the driver to quickly leave the scene. The light sensor (12) senses whether the sky light is insufficient. If the sky is dim and the weather is not good, the light sensor (12) senses and transmits the information to the LED flasher (13) via the single chip controller (11). The high brightness LED starts to flash. The ultrasonic range finder (15) measures whether the distance between the vehicle and the vehicle fault flag (10) is too close. If the vehicle is approaching, the vehicle fault flag (10) controls the wireless transmitter (14) to immediately stop transmitting the signal. The wireless alarm on the driver will immediately sound an alarm when the vehicle fails to receive the signal, alerting the driver to be alert.

The wireless alarm (20) comprises: a wireless receiver (21) and a sound output device (22), wherein the wireless receiver (21) is responsible for receiving the signal of the wireless transmitter (14), and when the middle of the signal, the sound is immediately activated. Output (22). When the wireless receiver (21) receives no signal, the sound outputter (22) will immediately generate an alarm sound.

In order to let your review committee know more about the multi-function vehicle fault sign, we will use Figure 1 to provide a detailed explanation. For example, first turn on the power of the vehicle fault sign (10) and move it to the rear of the vehicle, then wireless alarm. The device (20) is opened and worn to fasten on the wrist.

1. After the power is turned on, the wireless transmitter (14) starts transmitting a signal to the wireless receiver (21), and connects the vehicle fault flag (10) and the wireless alarm (20).

2. After the connection, the ultrasonic range finder (15) starts to detect. If the range of the ultrasonic wave senses the approach of the vehicle, the ultrasonic range finder (15) will quickly transmit the information to the single-chip controller ( 11), the single-chip controller (11) controls the wireless transmitter (14) to immediately stop transmitting the signal to the wireless receiver (21) of the wireless alarm (20), and the wireless receiver (21) will not receive the signal. The sound outputter (22) sounds an alarm.

3. If the vehicle fault flag (10) is knocked down by the vehicle and the detector of the dump detector (16) acts, the information is transmitted to the wireless transmitter (14) via the single-chip controller (11), and immediately The transmission of the signal to the wireless receiver (21) of the wireless alarm (20) is stopped, and the wireless receiver (21) causes the sound outputter (22) to sound an alarm due to the failure to receive the signal.

4. The wireless transmitter (14) and the wireless receiver (21) of the vehicle fault flag (10) can also measure the distance between the vehicle fault flag (10) and the driver. If the fault is eliminated, the driver will fail the vehicle. The sign (10) remains on site and leaves, the wireless receiver (21) of the wireless alarm (20) will be The sound outputter (22) sounds an alarm in order to receive no signal from the wireless transmitter (14).

5. If the sky is dim and the weather is not good, the light sensor (12) senses and transmits the information to the LED scintillator (13) via the single chip controller (11) to make the high brightness LED start to flash.
