Background technology
Blind monitoring system is that auto vendor designs in high speed or crowded urban transportation driver to better meet.Concrete principle is through ultrasound wave, radar, the first-class device of shooting, when vehicle travels, the blind area of vehicle both sides is detected, if there being other vehicles to enter blind area, at rearview mirror or other appointment positions, driver can be pointed out, thus inform that when driver is the preferably opportunity of doubling, considerably reduce the accident occurred because of doubling
Blind monitoring system is a key function in drive assist system, covers 360 ° of road conditions around vehicle body when lower-speed state.Active safety cycle detection system also includes adaptive learning algorithms, lane departur warning, parking sonar etc..This system allows driver drive a vehicle to become safer, especially during driving for a long time.
Domestic producer mainly uses ultrasound wave to detect, and this technology has the obvious disadvantage that: one, detection range are short, the detection range less than 10 meters；Its two, be easily subject to environmental disturbances, such as wind speed can affect Effect on Detecting；It three can not penetrate plastics due to ultrasound wave, so must punch at vehicle body, adds installation cost.
Utility model content
The purpose of this utility model is to solve the problems referred to above and proposes a kind of automobile blind spot based on radar sensing technology monitoring system, owing to employing 24GHz radar sensor, this utility model is made on the one hand to improve detection range, on the other hand the anti-interference of environment can also be improved, ensure that product can normally work under circumstances, in addition, owing to 24GHz radar sensor can penetrate plastics, so without punching at vehicle body, maintain the integrity of vehicle body and attractive in appearance, and reduce installation cost.
To achieve these goals, the technical scheme that this utility model is taked is as follows:
The utility model proposes a kind of automobile blind spot based on radar sensing technology monitoring system, described monitoring system includes: 24GHz radar sensor, and described 24GHz radar sensor is two and is respectively arranged on the left and right sides of rear bumper arm on car；Radar sensor master switch, within automobile cabin is located at by described radar sensor master switch, described radar sensor master switch is connected to 24GHz radar sensor；Indicator, described indicator is two and is respectively arranged on left and right outside rear-view mirror, and described indicator is connected to be placed in the 24GHz radar sensor of the left and right sides of bumper bar；Signal Regulation bar, within described Signal Regulation bar is arranged at automobile cabin, described Signal Regulation bar is connected with indicator.
Further, described indicator is LED.
Further, filter amplification circuit, sample circuit, AC-DC change-over circuit, signal processor, signal output apparatus and signal delay circuit also it are sequentially provided with between described 24GHz radar sensor and indicator.
Further, described signal delay circuit is two and corresponds respectively to two indicators.
The beneficial effects of the utility model:
1. compared with the mode using ultrasound wave to carry out detecting, this utility model utilizes 24GHz radar sensor to make this utility model on the one hand improve detection range, the detection range of 50-100 rice can be reached, when running at high speed, advantage is clearly, on the other hand the anti-interference of environment can also be improved, ensure that product can normally work under circumstances, in addition, owing to 24GHz radar sensor can penetrate plastics, so without punching at vehicle body, maintain the integrity of vehicle body and attractive in appearance, and reduce installation cost；
2. this utility model uses advanced filter amplification circuit and Digital Signal Processing, and is optimized signal processing algorithm, thus effectively eliminates interference and the wrong report of complex road condition；
3.24GHz belongs to international ISM band, and product can be used in whole world most countries and area.
Accompanying drawing explanation
Fig. 1 is functional-block diagram of the present utility model；
Fig. 2 is the schematic diagram that this utility model is installed on automobile.
Wherein, 1-24GHz radar sensor, 2-radar sensor master switch, 3-indicator, 4-Signal Regulation bar, 5-filter amplification circuit, 6-sample circuit, 7-AC-DC change-over circuit, 8-signal processor, 9-signal output apparatus, 10-signal delay circuit.
Detailed description of the invention
Accompanying drawing below in conjunction with embodiment carries out clear, complete description to the technical scheme of this utility model embodiment; the most described embodiment is only a part of embodiment of the present utility model; based on embodiment of the present utility model; the other embodiments that those of ordinary skill in the art is obtained on the premise of not making any creative work, broadly falls into protection domain of the present utility model.
As shown in Figure 1-2, the utility model proposes a kind of automobile blind spot based on radar sensing technology monitoring system, including 24GHz radar sensor 1, described 24GHz radar sensor 1 is two and is respectively arranged on the left and right sides of rear bumper arm on car；Radar sensor master switch 2, within automobile cabin is located at by described radar sensor master switch 2, described radar sensor master switch 2 is connected to 24GHz radar sensor 1；Indicator 3, described indicator 3 is two and is respectively arranged on left and right outside rear-view mirror, and described indicator 3 is connected to be placed in the 24GHz radar sensor 1 of the left and right sides of bumper bar；Signal Regulation bar 4, within described Signal Regulation bar 4 is arranged at automobile cabin, described Signal Regulation bar 4 is connected with indicator 3.
This utility model uses 24GHz radar sensor (such as the K-LC2 of RFbeam company), this sensor charge of overseeing vehicle back and path space of side, and shows a visual signal in outside rear-view mirror, exists with the automobile storage pointing out blind spot region whether to have motion.Specifically, above-mentioned indicator 3 is lED lamp, when speed >=15km/h, this cover system can be by the 24GHz radar sensor being hidden in the rear bumper left and right sides, the distance at about 20 meters of vehicle body rear is monitored in real time, once side back car, car running computer can find side rear barrier vehicle in time, if steering indicating light to be beaten lane change in this time, the LED of native system will flash reminds driver rear flank side to have obstacle vehicle, if and do not prepare this time to spin to lamp lane change, then LED then can keep bright state, and does not flashes；Additionally, the type of alarm of this set blind monitoring system is also thought deeply through sufficient hommization, LED can directly be lighted on rearview mirror surface, this benefit done is under not disperseing driver attention's premise, driver is reminded to pay close attention to rear flank side's danger hidden danger, and react in time, thus avoid the vehicle collision even generation of traffic accident, apart from the above, have and a little highly one be mentioned that, blind monitoring system is in the case of the reversing of≤12km/h speed per hour, and system can automatically identify the close of rear mobile object, and gives a warning.
