Description

Workshop collaborative early warning device based on pedestrian protection

technical field

The utility model relates to the fields of traffic safety and electronics, in particular to a workshop cooperative early warning device based on pedestrian protection.

Background technique

Due to the complex road traffic conditions in our country, the phenomenon of pedestrian casualties and traffic accidents is relatively serious. At present, in terms of active safety of automobiles, information is mainly provided to drivers through sensors and image acquisition, so that drivers can respond in time. In reality, if the driver does not find the pedestrians in front in time, it is likely to cause a collision between the vehicle and the pedestrians in front or to take emergency braking measures in order to avoid the pedestrians in front. The vehicle behind is likely to collide with the vehicle. In addition, in order to warn the pedestrians or vehicles in front of the driver, the rapid car whistle will also cause a certain amount of noise pollution to the environment.

Contents of the invention

The purpose of this utility model is: in order to solve the above-mentioned technical problems in the prior art, provide a kind of workshop cooperative early warning device based on pedestrian protection, through the transmission of the workshop alarm signal and the alarm signal to the driver to achieve the purpose of protecting pedestrians . It can not only solve the problem of traffic accidents to a certain extent, but also the ultrasonic signal device in the utility model can avoid the car whistle and solve the problem of car noise pollution.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is to provide a vehicle-to-vehicle cooperative early warning device based on pedestrian protection, including: a human body sensor 1 installed at the front of the car and an ultrasonic signal for receiving the warning signal of the car ahead Receiver 7, vehicle speed sensor 2 on the engine, central processing unit 3 for receiving and processing information, sound signal device installed inside the car, and ultrasonic signal transmitter 6 installed at the rear of the car for sending alarm signals; The sound signal device further comprises: a sound signal warning device 4 and a sound signal warning device 5; The central processing unit 6 is signal-connected; the ultrasonic signal transmitter 6 is connected with the sound signal alarm device 5. The ultrasonic signal transmitter 6 can only receive the signal sent by the alarm horn, but cannot receive the signal sent by the buzzer.

Wherein, the sound signal warning device 4 uses a buzzer to sound.

Wherein, the sound signal alarm device 5 uses an alarm horn to sound.

Wherein, the central processing unit 3 is composed of a single-chip computer.

Beneficial effects: the utility model studies pedestrians and vehicles as a system, detects the pedestrians in front through the human body sensor on the car, and then transmits this information to the driver and the rear vehicle in time, while protecting the safety of the pedestrians in front , which reduces the possibility of danger to the rear vehicles caused by the emergency response of the vehicles in front, and achieves the function of workshop cooperative early warning. The ultrasonic signal device it adopts also avoids the noise pollution caused by the driver's honking of the car.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing and embodiment.

Referring to Fig. 1, the vehicle-to-vehicle cooperative early warning device based on pedestrian protection of the utility model includes two transmission modes: the first transmission mode is the human body sensor 1 (human body sensor switch module) based on infrared technology located at the front of the car and the human body sensor 1 located on the engine. The vehicle speed sensor 2 first starts to work, and transmits the real-time information collected to the central processing unit 3, that is, a single-chip microcomputer. The central processing unit 3 performs data analysis according to the information transmitted by the vehicle speed sensor 2, and makes different treatments. Take the information transmission as shown in Figure 2 under the situation of taking, take the information transmission as shown in Figure 3 under the higher situation of vehicle speed; Namely send to sound signal warning device 4 or sound signal warning device 5, thereby reach driver can Respond in time for the purpose of protecting pedestrians.

The second way of transmission, the sound signal alarm device 5 uses the car horn to send an alarm signal, this alarm signal is not only obtained by the driver in the car, but also passed to the ultrasonic signal transmitter 6 installed at the rear of the car, the ultrasonic signal transmitter 6 This alarm signal is delivered to the ultrasonic signal receiver 7 at the front of the rear vehicle, and the ultrasonic signal receiver 7 delivers the alarm signal to the central processing unit 3, which is a single-chip microcomputer. An alarm signal is issued, which reminds the driver to take corresponding measures in time if the vehicle in front of him occurs.

With reference to Fig. 2, the human body sensor 1 can obtain the pedestrian information in front, the vehicle speed sensor 2 obtains the speed value of the current automobile, and sends the signals of the two to the central processing unit 3 in real time, and when the central processing unit 3 detects that the vehicle speed is low, it will Can send signal to sound signal warning device 4, send warning sound by buzzer, and this signal can not be received by the ultrasonic transmitter device of this car rear portion.

Referring to Fig. 3, the human body sensor 1 can obtain the pedestrian information in front, the vehicle speed sensor 2 obtains the speed value of the current car, and sends the signals of the two to the central processing unit 3 in real time, and the central processing unit 3 detects that the vehicle speed is high. The sound signal alarm device 5 sends a signal, and the alarm horn will send an alarm sound, and this alarm sound will be passed to the ultrasonic signal transmitter 6 installed at the rear of the car, and then the ultrasonic signal transmitter 6 sends a signal to the vehicle at the front of the rear. The ultrasonic signal receiver 7, the ultrasonic signal receiver 7 sends the signal to the rear vehicle central processing unit 3, and the rear vehicle central processing unit 3 sends a signal to the rear vehicle sound signal alarm device 5, and the alarm device will remind the driver to take corresponding measures in time. measure.

The two different transmission modes are mainly controlled by the central processing unit 3 and the ultrasonic signal transmitter 6 . Under the low situation of vehicle speed, central processing unit 3 can send signal to sound signal warning device 4, and ultrasonic signal transmitter 6 can not receive the smaller warning sound that sends by buzzer, under the comparatively simple situation of structure A better early warning effect has been achieved, and the dual functions of pedestrian safety and mutual early warning of the workshop have been realized.

The above content is a further detailed description of the present invention in combination with preferred technical solutions, and it cannot be assumed that the specific implementation of the invention is limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, simple deduction and substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention. the
