Description

A vehicle speed alarm device

technical field

The utility model relates to the related technical field of automobile parts, in particular to a vehicle speed alarm device.

Background technique

At present, many traffic accidents on high-speed roads are caused by vehicles speeding. Due to the high-speed road conditions and long-term driving, it is difficult for many drivers to notice it after speeding, which is likely to cause traffic accidents. At the same time, it is not caused by human consciousness. Speeding fines, etc., cause unnecessary economic losses to yourself. Current vehicles are not equipped with mechanisms and devices related to speed alarms, so it is impossible to remind drivers not to speed on high-speed roads, because the high-speed road conditions are good, and they do not know that they are speeding when driving, resulting in safety accidents. Increased own fines for speeding.

Chinese patent authorization announcement number: CN202649227U, authorized announcement date January 2, 2013, discloses a vehicle speed measurement and speed limit alarm device, the device is composed of a magnetoelectric sensor for measuring vehicle speed, a single-chip microcomputer, a vehicle speed setting module, an alarm The magnetic sensor and the vehicle speed setting module are respectively connected to the signal input end of the single-chip microcomputer, and the signal output end of the single-chip microcomputer is connected to the alarm unit. The disadvantage of this utility model is that only the speed of driving is detected by the magnetoelectric sensor, the speed setting module is used to set the required speed, and the comparison between the two is carried out to realize the function of speed limit alarm. This device has a single function, The impact of other external factors on the vehicle speed cannot be considered, resulting in certain errors in the detected vehicle speed, and at the same time, it cannot effectively eliminate the problems existing in the vehicle and some unforeseen safety factors.

Utility model content

The utility model aims at overcoming the above-mentioned deficiencies in the prior art, and provides a simple, practical, safe and reliable vehicle speed alarm device.

In order to achieve the above object, the utility model adopts the following technical solutions:

A vehicle speed alarm device includes a vehicle speed sensor, a pressure sensor, a distance sensor, a controller, a touch screen and an alarm device, and the vehicle speed sensor, pressure sensor, distance sensor, touch screen and alarm device are all connected to the controller.

The speed of the vehicle is detected by the speed sensor, the tire pressure of the car tire is detected by the pressure sensor, and the rolling radius of the wheel is detected by the distance sensor. The combination of the three can eliminate the speed problem caused by the wheel problem to ensure the speed of the vehicle. The reliability of the vehicle speed detected by the sensor, and at the same time set the required vehicle speed through the touch screen, so that the two can be compared to realize the alarm function. This design achieves the purpose of simplicity, practicality, safety and reliability.

Preferably, a humidity sensor is also included, and the humidity sensor is connected with the controller. The humidity sensor is used to detect the external environment, such as the impact of rainy weather conditions on driving and wheels, which further improves the safety and reliability of the device.

Preferably, a temperature sensor is also included, and the temperature sensor is connected with the controller. The temperature sensor is used to detect the external environment, such as the influence of the hot weather on the driving and the wheels, so as to further improve the safety and reliability of the device.

Preferably, the pressure sensor is installed on the tire of the automobile, and the distance sensor is installed at the center of the hub of the automobile.

Preferably, the controller is a single-chip microcomputer or a driving computer. The device can be installed and disassembled separately, and can also be directly integrated on the trip computer, thereby reducing production costs.

Preferably, the alarm device includes a voice alarm and a buzzer alarm. The voice alarm can directly remind the driver to take timely measures to prevent it, and the buzzer alarm can continuously remind the driver to remove the existing faults.

The beneficial effects of the utility model are: simple and practical, low cost, safe and reliable, can be completely set by the driver according to the road conditions, and easy to operate.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

In the embodiment described in Fig. 1, a kind of vehicle speed warning device comprises vehicle speed sensor 1, pressure sensor 2, distance sensor 3, humidity sensor 5, temperature sensor 4, controller 9, touch screen 6 and warning device 10, vehicle speed sensor 1, pressure sensor 2, distance sensor 3, humidity sensor 5, temperature sensor 4, touch screen 6 and alarm device 10 are all connected with controller 9, and controller 9 is single-chip microcomputer or driving computer, and alarm device 10 comprises voice alarm 7 and beeper Sound the alarm 8. The pressure sensor 2 is installed on the tire of the car, and the distance sensor 3 is installed at the center of the hub of the car.

The alarm device allows the driver to set the safe driving speed of the vehicle through the touch screen 6 according to different road conditions. When the vehicle is in the driving state, the system monitors the vehicle at all times through the speed sensor 1 and detects it through the pressure sensor 2 and the distance sensor 3 at the same time. Whether the state of the car tires is in a normal state, the impact of the external weather environment on the vehicle and the car tires is detected through the humidity sensor 5 and the temperature sensor 4, and the existing problems are eliminated through the combination of the three, and it can also be determined through the touch screen 6. Afterwards, when it is found that the vehicle speed exceeds the maximum speed set by the driver, the controller 9 starts to alarm through the alarm device 10. On the one hand, the voice alarm 7 is used to alarm to remind the driver to slow down; Sound alarm 8 to report to the police, so that the driver can know in time whether the vehicle is in the scope of the safe value.
