Beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model is scalable and can arbitrarily angled fixing camera by one, angular adjustment with camera puts in place in use, then read by video input circuit, and the corresponding Fumction display of combination is on telltale.The utility model has been finished the function of a plurality of cameras by a camera, is reduced so that be installed in the quantity of the camera on the automobile.
Description of drawings
Fig. 1 is block diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to a kind of vehicle-mounted information system device that possesses multifunctional pick-up head, scalable and can arbitrarily angled fixing camera by one, angular adjustment with camera puts in place in use, then read by the video input interface circuit, and the corresponding Fumction display of combination is on telltale.The utility model has been finished the function of a plurality of cameras by a camera, is reduced so that be installed in the quantity of the camera on the automobile.
As shown in Figure 1, a kind of vehicle-mounted information system device that possesses multifunctional pick-up head comprises the scalable and camera that can arbitrarily angledly be fixed, is used for the functional module that external video to input carries out video input interface circuit that impedance match and filtering processes, is used for carrying out analog switch and a plurality of inter-vehicle information systems of video switch; The mouth of described camera links to each other with described video input interface; The mouth of described video input interface links to each other with described analog switch; Each mouth of described analog switch links to each other with corresponding functional module respectively.In the present embodiment camera clap picture by the video input interface circuit it is carried out impedance match and filtering and processes, then carry out video switch by analog switch, realize corresponding function thereby it is communicated with corresponding functional module.
Wherein, camera can be fixed on the optional position on the interior operator platform of car.The cable of camera is connected on the video input interface of inter-vehicle information system.Described functional module can be real scene navigation instrument, drive recorder or the computing machine that Video chat software is housed.
The video input interface circuit comprises impedance matching circuit and the filter circuit of successively series connection.Wherein, impedance matching circuit can adopt L shaped matching circuit, and this circuit has simple in circuits and lower-cost advantage.Owing to will consider to mate the loss with power, use inductance and capacitive element as far as possible, want impedance matching circuit reasonable in design will select suitable capacity reactance component parameters, the computing element parameter has two class methods: directly calculate and pass through smith's chart by impedance.The former advantage is to calculate accurate and suitable computing machine to calculate, and the latter is a kind of actv. design directly perceived, can sufficiently and reasonably select optimal performance.Filter circuit can adopt active filter circuit, and the load of active filter circuit can not affect Filter characteristics, therefore is usually used in the high occasion of signal processing requirement.Active filter circuit in the present embodiment is comprised of RC network and integrated transporting discharging, thereby must could use in the situation of suitable DC power supply, can also amplify simultaneously.
Described analog switch is single eight path analoging switch CD4051, and this analog switch is equivalent to hilted broadsword eight throw switches, and which passage of switch connection is decided by the 3 bit address code ABC that input.Wherein, " INH " forbids end, and when " INH "=1, each passage is all disconnected.In addition, single eight path analoging switch CD4051 also are provided with another one power end VEE, use with as level shift the time, thereby so that the digital signal that the cmos circuit of usually working under single group Power supply condition provides can directly be controlled this multiple way switch, and make this multiple way switch can transmit the AC signal that peak-to-peak value reaches 15V.For example, if the power supply VDD=+5V of analog switch, VSS=0V, when VEE=-5V, as long as this analog switch is applied the digital controlled signal of 0～5V, just can control amplitude range and be-5V～+ analog signal of 5V.According to practical application, camera video is switched in real time.Want to use the application of real scene navigation such as present user, can video switch be arrived " real scene navigation " functional module by analog switch.
Below working process of the present utility model is described.The user is fixed on camera first the optional position on the operator platform in the car, and then the cable with camera is connected on the video input interface of inter-vehicle information system.If the user need to use real scene navigation to use, can select by inter-vehicle information system, after selection is finished, camera can arrive proper angle according to user's selection Self-adjustment, camera begins the graphicinformation in collection vehicle dead ahead, and with the image transmission that collects to the video input interface circuit, by the video input interface circuit graphicinformation of input is carried out impedance match and filtering processing, and then by analog switch selection real scene navigation instrument, video switch is arrived " real scene navigation " functional module, will show the real scene navigation map on the read-out of inter-vehicle information system at this moment, thereby realize the application of real scene navigation.If wanting to switch when using real scene navigation to use, the user use driving recording to use, then only need to switch to drive recorder by inter-vehicle information system, camera is adjusted to proper angle according to user's selection automatically, and gather corresponding graphicinformation, then with image transmission to the video input interface circuit, select drive recorder by analog switch, video switch is arrived " driving recording " functional module, will show the driving recorded information on the read-out of inter-vehicle information system, thereby realize the application of driving recording.
Be not difficult to find, the utility model is scalable and can arbitrarily angled fixing camera by one, and the angular adjustment with camera puts in place in use, then read by video input circuit, and in conjunction with corresponding Fumction display on telltale.The utility model has been finished the function of a plurality of cameras by a camera, is reduced so that be installed in the quantity of the camera on the automobile.
