Description
Technical field
The utility model relates to the automobile equipment technical field, more particularly relates to the reversing automobile supervising device of radar type.
Background technology
Along with development of electronic technology, modern automobile is developed to comprehensive Electronic Control direction by original mechanical manual control.As traditional reversing radar of vehicle, generally be installed in the boot of automobile, and by circuit connection warning horn, by sound wave emissions sensor emission ultrasonic signal, after running into the barrier reflection aloft, receive by the ultrasound wave receiving sensor again and convert electric signal to, give microprocessor through ultrasound wave receiving circuit processing and amplifying back reflection signal, and drive the warning horn jingle bell.But, because the microprocessor operated by rotary motion is on automobile control panel, radar for backing car is connected by data line with microprocessor, the safety of whether need considering during installation to connect up, factor such as firm, influence production efficiency, for this reason, people add the wireless data transmission circuit on traditional reversing radar of vehicle, as Chinese patent application number is 97237819, the applying date is on October 10th, 1997, denomination of invention is many probe wireless automobile vehicle backing backsight collision avoidance radars, it is characterized in that having a plurality of ultrasonic sensor probes to place automobile rear, ultrasonic transmit circuit is by ultrasonic emitting sensor emission ultrasonic signal, run into the barrier reflection aloft after, receive by the ultrasound wave receiving sensor again and convert electric signal to, after ultrasound wave receiving circuit processing and amplifying, give microprocessor by measuring the ultrasonic signal emission, the receive delay time calculates the distance of car and obstruction, and encoded back is sent out by the emission of wireless data transmission circuit.After the wireless data receiving circuit of the display of this patent by placing the car front portion amplified shaping with the signal that receives, the input data decoder decodes is presented at distance signal on the screen by display driver circuit, and was easy to install and use.The shortcoming of this patent is that display and collision avoidance radar are the auxiliary products of independent design, and function singleness takies the too much space of automobile control panel.Vertical institute is known, and data can only reflect distance, and the external environment of reflection automobile rear that can not be concrete, observation is inconvenient.
Summary of the invention
That the purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of not only installs and removes, observes is convenient, production efficiency is high, and the radar type reversing automobile supervising device that combines together with automobile.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of radar type reversing automobile supervising device, comprise video camera, radar for backing car inductor and vehicle carried video equipment, video camera, radar for backing car inductor connect the wireless data transmission module respectively, it is characterized in that: the main frame of described vehicle carried video equipment is provided with the wireless data receiver module that is connected with the wireless data transmission module communication.
As further specifying of such scheme, wireless data transmission module and wireless data receiver module comprise oscillatory circuit, control circuit and microprocessing unit, wireless data transmission module and wireless data receiver module are equipped with transmission end and receiving end, this receiving end comprises demodulator circuit, communication interface and CPU (central processing unit), demodulator circuit connects the microprocessor of single-chip microcomputer, microprocessor connects communication interface, and communication interface is connected with CPU (central processing unit).
Described radar for backing car inductor comprises ultrasonic emitting and the receiving circuit by two or more sets ultrasonic emitting sensors and receiving sensor, and it is the above ultrasonic emitting sensor of 10m that ultrasonic transmit circuit adopts transmitting range.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model adopts the connected mode of radio communication that radar for backing car inductor and video camera are sent the main frame of data message to vehicle carried video equipment after signal processing circuit, realize that audio-visual broadcast combines with the reversing monitoring, not only easy to install, good looking appearance, can also realize the moveing backward purpose of omnidistance video monitoring improves the security performance of automobile itself.
