In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by the following embodiments, which are taken in conjunction with the accompanying drawings.
The embodiment of the utility model provides a vehicle blind area monitoring and early warning system 100.
The vehicle blind spot monitoring and warning system 100 may be applied to a vehicle 1000, such as an automobile. The blind area is an area where the vehicle 1000 is not easily observed, and taking an automobile as an example, the blind area is an area where a driver is located at a normal driver seat and the sight line of the driver is shielded by a vehicle body and cannot be directly observed. The target is other obstacles such as cars, pedestrians, railings, trees, and the like. By detecting whether the target exists in the blind area and sending out an alarm signal when the target exists in the blind area, monitoring and early warning of the blind area can be achieved, and the vehicle 1000 is prevented from touching the target.
Of course, the vehicle blind area monitoring and early warning system 100 can also be applied to the security field of static monitoring, such as the anti-theft alarm field. The blind area is an area adjacent to a normal activity area of a legal user, and the target is an illegal user. By monitoring and early warning the blind area, the target is prevented from entering the blind area, so that the economic property safety of a normal activity area and the personal safety of a legal user are ensured.
Referring to fig. 1, a vehicle blind area monitoring and warning system 100 includes a distance detecting device 10 and a warning device 20. The utility model discloses a vehicle 1000 uses the car as an example, explains vehicle blind area monitoring and early warning system 100 in detail.
The distance detection device 10 is configured to detect a distance between an object and the vehicle 1000, and generate a trigger signal according to the distance.
The distance detection means 10 may detect the presence or absence of an object by means of ultrasonic waves, millimeter waves, laser light, a camera, or the like. Taking the ultrasonic wave as an example, the distance detecting device 10 transmits the ultrasonic wave to the outside, and if there is a target in the blind area, the distance detecting device 10 also receives the ultrasonic wave reflected by the target, and based on the time of transmitting the ultrasonic wave and the time of receiving the reflected ultrasonic wave, the distance between the target and the distance detecting device 10, that is, the distance between the target and the vehicle 1000 can be calculated.
The warning device 20 is configured to send a warning signal after receiving the triggering signal and the steering signal of the vehicle 1000.
The alarm device 20 is electrically connected to the distance detecting device 10 to receive a trigger signal of the distance detecting device 10. In one embodiment, the distance detecting device 10 and the warning device 20 can be connected by a wire harness and a connector, so that the distance detecting device 10 and the warning device 20 can be separately arranged at different positions of the vehicle 1000, and the installation is flexible. In addition, the wire harnesses of each part are integrated in the large wire harness, so that the installation of the vehicle blind area monitoring and early warning system 100 is more convenient. Wherein the warning device 20 may be powered by the vehicle 1000.
The warning device 20 is also used to electrically connect with the vehicle 1000 to receive a steering signal of the vehicle 1000. The steering signal of the vehicle 1000 includes a left steering signal and a right steering signal. Taking the vehicle 1000 as an example, if the driver wants to change lanes, a left steering control message or a right steering control message is input to the vehicle 1000, and the vehicle 1000 makes a left turn preparation, such as turning on the left turn light 200 (see fig. 2), according to the left steering control message. At this time, the warning device 20 may receive a left turn signal of the vehicle 1000. The vehicle 1000 makes a right turn preparation, such as turning on the right turn light 300 (fig. 2), according to the right turn control message, and the warning device 20 may receive the right turn signal of the vehicle 1000. When the alarm module 20 only receives the steering signal, the alarm module 20 does not send out the alarm signal; when the alarm module 20 receives only the trigger signal, the alarm module 20 does not issue an alarm signal either. The alarm signal is only issued when the alarm module 20 receives both the turn signal and the trigger signal.
The utility model discloses vehicle blind area monitoring and early warning system 100's theory of operation continues to use vehicle 1000 as the car for the example, explains. After the vehicle 1000 is started, the vehicle blind area monitoring and early warning system 100 is also started, and the distance detection device 10 starts to detect whether a target exists in the blind area. If the driver wants to change lanes, the warning device 20 only receives one kind of steering signal, i.e. the left steering signal or the right steering signal, and therefore, when the trigger signal of the distance detecting device 10 is received again, the warning device 20 only sends out one kind of warning signal.
To sum up, the utility model discloses in vehicle blind area monitoring and early warning system 100, distance detection device 10 surveys the distance between target and the vehicle 1000 to according to the distance generation trigger signal. The warning device 20 sends a warning signal according to the trigger signal and the steering signal of the vehicle 1000 to remind a user to avoid a target, so that the function of monitoring and warning a blind area of the vehicle 1000 is realized, and the moving safety factor of the vehicle 1000 is improved. In addition, since the vehicle 1000 has different turn signals, such as left turn signal and right turn signal, the warning device 20 only sends out a warning signal when receiving a turn signal, so as to effectively avoid warning conflict and unnecessary warning, facilitate the user to make a decision quickly, and reduce energy consumption.

The ultrasonic detection device 11 is capable of emitting ultrasonic waves, for example, converting electric energy into acoustic energy under the action of high frequency and high voltage to emit the ultrasonic waves. The ultrasonic detection device 11 can also receive ultrasonic waves. If the target exists in the blind area, the transmitted ultrasonic wave is reflected by the target, and the ultrasonic detection device 11 receives the reflected ultrasonic wave, so that the target exists in the blind area and a trigger signal is generated.
Compared with a millimeter wave detection device, the millimeter wave detection device has the advantages that technical difficulty is high, for example, simulation development of an antenna, building of an internal hardware circuit, and difficulty in related algorithms are high, so that the mass production difficulty is high, the production cost is high, the ultrasonic detection device 11 is mature in technology and low in production cost, and therefore the ultrasonic detection device 11 is adopted by the distance detection device 10, and the production cost can be effectively reduced. In addition, current side position blind area early warning device requires highly to the installation, and the installation is not convenient, is not suitable for after-market, and the utility model discloses 11 sizes of ultrasonic detection device are less, and vehicle blind area monitoring early warning system 1000's whole size is also less, and the installation is convenient, is applicable to after-market.

In this way, the vehicle blind area monitoring and early warning system 100 can obtain a more accurate trigger signal.
In one embodiment, the ultrasonic detection device 11 includes a piezoelectric element and a processing chip.
The piezoelectric element is used for transmitting ultrasonic waves and generating echo signals after receiving the ultrasonic waves reflected by the target. Based on the piezoelectric effect, the piezoelectric element can convert electric energy into sound energy to emit ultrasonic waves; and the ultrasonic wave reflected by the target can be received, so that the sound energy is converted into electric energy to generate an echo signal.
The processing chip is electrically connected with the piezoelectric element and used for processing the echo signal to calculate the distance between the target and the vehicle 1000 and generating a trigger signal according to the distance. Wherein the echo signal contains time information of the piezoelectric element receiving the ultrasonic wave reflected by the target. The processing chip 12 can calculate the distance between the target and the vehicle 1000 from the echo signal and the time information of the ultrasonic wave emitted by the piezoelectric element, and generate a trigger signal according to the distance.
Because ultrasonic detection device 11 can survey and calculate the distance between target and the ultrasonic detection device 11, consequently, vehicle blind area monitoring and early warning system 100 need not to set up extra treater and calculates the distance between target and the ultrasonic detection device 11, is favorable to integrating of vehicle blind area monitoring and early warning system 100 for vehicle blind area monitoring and early warning system 100 is convenient for install to vehicle 1000 on, can also avoid with the interior mutual interference of communication of car.
