Abstract
The utility model discloses a car-backing auxiliary device for transmitting data by using direct-current power line carrier waves, which comprises a display unit (1), a control unit (2) and a detecting unit (3), wherein the display unit and the control unit are respectively provided with a power line carrier wave transmission processor (4); the two power line carrier wave transmission processors are connected by an automotive direct-current power line (5); the detecting unit conveys the data information for detecting an obstacle to the control unit; the power line carrier wave transmission processor in the control unit encodes and modulates the data and then couples the data into the power line; and the power line carrier wave transmission processor in the display unit demodulates and decodes the data received from the power line and then outputs the data to the display unit for displaying. The communication between the control unit and the detecting unit adopts the automotive direct-current power line as a data transmission carrier, and the high-speed data transmission can be carried out in the environment full of stray noise. When the car-backing auxiliary device for transmitting the data by using the direct-current power line carrier waves is mounted, the rewiring is not needed, the mounting is quite convenient, and the signal transmission can not be interfered.
Description
Technical field
The utility model belongs to the technical field of reverse aid, specifically is meant a kind of ultrasonic reverse aid of utilizing direct current supply line carrier-wave transmission data.
Background technology
At present, the signal transmission between each parts of traditional ultrasonic reverse aid generally has following several mode,
1, transmits signal by wire harness.Its advantage is that technology is simple, is easy to realize, its shortcoming is longer in wiring, and wire harness is subjected to the risk of coupled interference bigger, in addition, might destroy the interior trim integrality during installation, and it is longer that spended time is installed.
2, adopt wireless mode.The advantage of wireless mode is to need not wiring, and is easy for installation.Wireless mode comprises two kinds of electromagnetic transmission and infrared transmission.The shortcoming of electromagnetic transmission is the disturbed and peripheral vehicle that similar products are housed of interference with the data transmission meeting of frequency range, the data transmission of frequency conversion is then because of being limited by each regional laws and regulations in addition, it is rather complicated that the realization of technology becomes, thereby promoted cost of products.The shortcoming of infrared transmission is propagation characteristic and the environment inside car that is subject to light, the risk that being absorbed is arranged and stop.
The utility model content
The purpose of this utility model is to provide a kind of rewiring that need not, and utilizes direct current supply line in the car to carry out the reverse aid of carrier-wave transmission data.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the reverse aid of utilizing direct current supply line carrier-wave transmission data, comprise display unit, control module and probe unit, be respectively equipped with the power line carrier transmission processor on described display unit and the control module, two power line carrier transmission processors connect by the car direct current power supply line, described probe unit sends the data message of detecting obstacles thing to control module, power line carrier transmission processor in the control module is coupled into power lead again with digital coding with after modulating, power line carrier transmission processor in the display unit will carry out the demodulation sign indicating number from the data that power lead receives, and export to display unit then and show.
The power line carrier transmission processor of the control information of described display unit in display unit carries out being coupled into power lead again after the signal modulation, power line carrier transmission processor in the control module will carry out the demodulation sign indicating number from the data that power lead receives, and export to control module then.
Described probe unit is a ultrasonic probe.
Owing to adopted above-mentioned structure, the communication between control module of the present utility model and the probe unit adopts the car direct current power supply line as the data transmission carrier, carries out high speed data transfers in the environment that is full of spuious noise.When the utility model is installed on the automobile, need not rewiring, save wire harness, very convenient saving time is installed, the signal transmission can not be interfered, and transmission range is long, is applicable to the vehicle of various magnitudes of voltage, has very strong practicality and promotional value.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structured flowchart that utilizes the reverse aid of direct current supply line carrier-wave transmission data.
Embodiment
As shown in Figure 1, the reverse aid of utilizing direct current supply line carrier-wave transmission data described in the utility model, comprise display unit 1, control module 2 and probe unit 3, described probe unit 3 can be a ultrasonic probe, the principle of work of ultrasonic probe and control module 2 thereof is a prior art, is not described in detail.Be respectively equipped with 4, two power line carrier transmission processors of power line carrier transmission processor 4 on described display unit 1 and the control module 2 and connect, possess bidirectional communication function by car direct current power supply line 5.The modulation-demo-demodulation method of power line carrier transmission processor 4 is a prior art, is not described in detail.Power line carrier transmission processor 4 adopts the code encoding/decoding mode of high serious forgiveness and high reliability, and spurious signals such as reply burst are disturbed, and improve the accuracy rate and the reliability of data transmission.
When the information of control module 2 will be transferred to display unit 1 demonstration, described probe unit 3 sends the data message of detecting obstacles thing to control module 2, power line carrier transmission processor 4 in the control module 2 is coupled into power lead 5 again with digital coding with after modulating, power line carrier transmission processor 4 in the display unit 1 will carry out the demodulation sign indicating number from the data that power lead 5 receives, and export to display unit 1 then and show.
When display unit 1 has control information to be transferred to control module 2, the power line carrier transmission processor 4 of control information in display unit 1 carries out being coupled into power lead 5 again after the signal modulation, power line carrier transmission processor 4 in the control module 2 will carry out the demodulation sign indicating number from the data that power lead 5 receives, and export to control module 2 then.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
