Abstract
The invention relates to a method for quick frequency modulation and channel selection by using a knob. The method comprises the following steps of: setting a default step, wherein the frequency of a radio station correspondingly gets forwards or backwards by a default step every time when the knob is turned by a grid; subsequently adjusting the step corresponding to every turn of a grid of the knob according to the speed of adjusting the knob by a user and interruption frequency produced in adjustment of the knob; and circulating in turn until the frequency point radio station required by the user is found. By using the method, the frequency of adjusting the radio station by the user by using the knob can be effectively increased, the user experience is improved, and the market competition of a product can be improved for an in-vehicle infotainment system manufacturer.
Description
Technical field
The present invention relates to a kind of radio knob design, be specifically related to a kind of method that can utilize knob to reach fast frequency hopping channel selection.
Background technology
Most of in-vehicle multi-media systems have radio function, and are all also retaining the function that knob is manually adjusted platform in the multimedia system of a lot of high-end or low sides.For example user wants to listen to the radio station that is positioned at 100MHz channel, and the current 87.5MHz frequency range that is in, needs from 87.5MHz, to be transferred to 100MHz by manual knob, according to general design, needs turn at least 80 step-lengths to reach this frequency range, and the turn time is longer.And by step-length being strengthened while solving the problem of turn overlong time, must cause received radio station frequency range less.Even if be provided with automatic search function in some radio system, if but user is in a good location of signal, may be in 87.5MHz-100MHz(or 87.5MHz-108MHz-100MHz) radio station in wave band also has a lot, like this, user's rotation of still having to repeatedly just can complete the accurate location in radio station.Visible employing knob manually adjusts the design of platform perfect not enough at present, impersonalityization design.
Summary of the invention
For the problems referred to above, the invention provides a kind of method of utilizing the channel selection of knob fast frequency hopping.
the technical scheme that the present invention takes is: utilize the method for knob fast frequency hopping channel selection, the steps include:
(1) acquiescence step-length STEP is set, user starts to rotate knob, every rotation one lattice, and frequency of radio station stepping or step are moved back an acquiescence step-length STEP; Every rotation one lattice of knob just produce once and interrupt;
(2) monitoring, when time knob action, if user rotates the interruption times of knob generation more than set point number, is thought to enter next time and is adjusted; Otherwise execution step (6);
(3) enter after adjustment next time, judge that this adjusts the time interval of adjusting apart from last time is that this generation time of adjusting first interruption was adjusted the time interval that last interrupts generation apart from last time, if this time interval is in setting range, perform step (4), otherwise execution step (6);
(4) rotate lattice, frequency of radio station stepping or step are moved back the twice of current step-length, but are not more than the setting multiple of acquiescence step-length STEP;
(5) complete after this time rotation, return to execution step (2);
(6) user rotates knob, rotates lattice, if current step-length has been STEP, does not change; If current step-length >=2*STEP, frequency of radio station stepping or step are moved back half of current step-length, again enter step (2).
Preferably, the described setting range of step (3) is 500ms-1500ms.
Preferably, the described set point number of step (2) is 3-4 time.
Preferably, the described setting multiple of step (4) is 8 times.
compared with prior art, beneficial effect of the present invention is: can be good at solving the defect of the mode of frequency modulation channel selection in prior art, the frequency modulation method of channel selection of hommization is provided.
accompanying drawing explanation
fig. 1 is the method for the invention process flow diagram.
embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the present invention is explained in further detail.
The disclosed method of utilizing the channel selection of knob fast frequency hopping is based on adjust the operating speed of platform process to carry out real-time analysis to user, and makes a response fast, automatically adjusts knob and rotates corresponding frequency modulation step-length, realizes fast frequency hopping channel selection function.In described method, first arrange one and rotate the corresponding frequency adjustment of lattice step-length with radio knob, be called acquiescence step-length STEP, be every rotation one lattice of knob, corresponding frequency of radio station moves back an acquiescence step-length STEP with regard to stepping or step, follow-uply according to operator, adjusts the speed of knob and adjusts the interruption times that knob produces the corresponding step-length of every rotation one lattice of knob is adjusted.
Conventionally in design, every rotation one lattice of knob just produce once and interrupt.General user's a spinning movement may have four or five interruptions, and the number of times of rotation than comparatively dense time, it has been generally acknowledged that from target frequency distant, corresponding strengthened step-length, otherwise, the corresponding step-length that reduces; In addition, in time, if the time interval of twice adjustment in setting range, thinks distant from target frequency, can strengthen step-length, otherwise, the corresponding step-length that reduces, the method for the invention is also based on this design.
As Fig. 1, the idiographic flow of the method is:
(1), when user rotates knob for the first time, the rule that frequency of radio station moves back an acquiescence step-length STEP according to stepping or step changes; In frequency adjustment process, system detects knob-operated in real time, if total interruption several number that rotation produces is in 3 times, the rule that frequency of radio station moves back (current step-length/2) according to stepping or step changes, if but current step-length has been STEP, do not change;
(2), if total number of interruptions that rotation produces reaches more than 3 times or 3 times, think that working as time tune platform finishes, and adjusts platform operation and enter next time;
(3) upper, once adjust in platform operation, need the break period for the first time of this knob rotation generation of further judgement apart from adjusting last time platform to interrupt for the last time the time interval producing, if this time interval does not meet setting range, be not greater than 500ms and be less than 1500ms, the rule that frequency of radio station moves back (current step-length/2) according to stepping or step changes, if but current step-length has been STEP, does not change; Continue again to detect the time interval between twice interruption; Once as this time interval meets the setting range that is greater than 500ms and is less than 1500ms, the rule that frequency of radio station moves back (the current step-length of 2*) according to stepping or step changes, but current step-length must not be greater than the acquiescence step-length of 8 times;
(4) be back to the incipient stage, continue the interruption times that monitor user ' rotation knob produces, circulation successively, until find the required frequency-point broadcasting station of user.
In said process, judge that the interruption monitoring number of times of twice adjustment institute foundation can specifically be set according to actual conditions, be preferably 3 times; Step-length adjusts the setting-up time scope of institute's foundation and the maximum of step-length is adjusted multiple, can specifically set according to actual conditions too, and setting-up time scope is preferably 500ms-1500ms, sets multiple and is preferably 8 times.
The method of the invention is not limited to radio knob rotation frequency modulation, can be applied to any similar employing knob and adjust the situation that fixed point is found that realizes.
Above-described embodiment is the preferred version that the present invention realizes, and it should be noted that, conceives under prerequisite not departing from the present invention, and any apparent replacement and subtle change are all within protection scope of the present invention.
