Accompanying drawing 1 is provided with the flow chart of frequency approach for broadcast receiver button according to the invention.
Embodiment
In order to let those skilled in the art understand technical scheme of the present invention better, the present invention is done further elaboration below in conjunction with accompanying drawing.
A kind of broadcast receiver button is provided with frequency approach, may further comprise the steps;
The wait button is pressed step, when button is not pressed, is in wait state always, and the record button that when button is pressed, rises below getting into is pressed the duration step;
The record button is pressed duration, presses from button and only plays button release constantly constantly, and the record button is pressed duration; As long as button does not discharge, clocking does not just stop, after button discharges; The zero clearing of clocking, time in next time, the record of button duration can be realized by timer.T1, T2 are that button is pressed duration and T1 < T2.
Button is pressed duration less than the T1 execution in step: if button is not released in the time at T1, then do not carry out any operation, if button is released in the time at T1; Carry out corresponding operating according to key-press status; Described key-press status comprises the general state that presses down the next radio station of automatic search, presses down frequency steps further often by state, and button is pressed the overlength in frequency step M step by state; Described M is the natural number of 5-15, and we preferred M is 10.
Button press duration more than or equal to T1 less than the T2 execution in step; Be set to often by state at T1 time point key-press status; Light every further from the T1 time, during this period of time press step if button release then jumps to described wait button at a distance from a time interval T3 frequency steps;
Button is pressed duration more than or equal to the T2 execution in step; Be set to extraordinary at T2 time point key-press status by state; Light whenever from the T2 time, during this period of time press step if button release then jumps to described wait button at a distance from a time interval T4 frequency step M step.
Button is pressed duration less than the T1 execution in step, button press duration more than or equal to T1 less than the T2 execution in step, button is pressed duration more than or equal to the T2 execution in step.The execution of these three steps is to be order with button according to the duration; The necessary condition of the execution of the step that is implemented as the back of the step of front; The step that is to say the back must have the step of front, yet the execution of preceding step must not cause the execution of later step.Button continue according to, then this several steps is carrying out always in chronological order, in case button discharges, no matter go to any one step in these three steps, this step stops.
The time span of T3 and T4 does not have necessary relation, yet for the simple of process and the requirement of reduction to software and hardware, so preferred time span T3 equals T4.
After discharging button, if do not push button in the time at T5, key-press status reverts to general state again; This technical characterictic makes this method can look like the spring uniform quality; No matter key-press status is set long by state, still overlength is by state, can get back to general state through the T5 time, because the general state the most frequently used a kind of state that is button; Can reduce the step that User Status is switched by this method, this method operation easily.Also make this method that better robustness is arranged through this technical characterictic, in the time of user's operating mistake, do not know that perhaps how to operate; As long as the process T5 time can be got back to general state; Can resume operations, and the operation of front, the operation of back can not influenced.As for the setting of T5 time length, not restriction in theory, but should not be too short on substantial manipulation, be preferably greater than 5 seconds.
Step direction can be low frequency to high-frequency, and the application's method is applicable to that the channel selection direction is from the low frequency to the high-frequency.From the low frequency to the high-frequency, when frequency was gone to highest frequency, its next point was turned back to low-limit frequency.
Step direction can be high-frequency to low frequency, and the application's method is applicable to that the channel selection direction is from the high-frequency to the low frequency.From the high-frequency to the low frequency, when frequency was gone to low-limit frequency, its next point was turned back to highest frequency.
The broadcast receiver of utilization this method preferably has two buttons; Upwards search plain button (step direction can be low frequency to high-frequency) and a button (step direction can be high-frequency to low frequency) of searching for downwards for one; Through utilizing this two buttons; Can realize that not only upwards (downwards) searches plain radio station automatically, (downwards) stepping that can also realize conveniently making progress is provided with frequency of radio station, and upwards (downwards) is provided with frequency of radio station fast.
Described step frequency is exactly minimum adjusting frequency.For example the selection frequency of modulating FM is 87.5MHz ~ 108MHz, and just can there be a radio station in every separated 0.1MHz, and the step frequency of modulating FM is 0.1MH.And the selection frequency of amplitude modulation AM whenever just can have a radio station at a distance from 9KHz at 531 ~ 1096 kHz, and the step frequency that is to say AM is 9KHz.The described step, further just on step direction, a step frequency advanced.
The button general state of the application definition is our a kind of function common in other products of the same type; Be to click, unclamp hand, equipment automatically from low frequency point to high-frequency point (or from high-frequency point to the low frequency point); (FM is 0.1MHz with step frequency; AM is 9KHz) searching broadcasting station, when satisfying search condition, just play this radio station.
In order to realize the multiple function of button, the state that the application presses button defines, and according to pressing duration, has defined three states, and promptly general state is grown and pressed state, and overlength is pressed state, and is as shown in the table:
| Key-press status | Condition | State characteristic |
| General state | Interior release of back T1 time pushes button | Whenever search for next radio station automatically by one-touch |
| The long state of pressing | The back T1 that pushes button did not discharge in the time, and pressed duration above T2 | Whenever by frequency of a stepping, every at a distance from T3 if under this state, continue to press, frequency of stepping |
| Overlength is pressed state | The duration that pushes button surpasses T2, and from being no more than T3 by doing button for the last time | Whenever by a stepping M frequency, every at a distance from T4 if under this state, continue to press, a stepping M frequency |
Button among the application have long by with overlength by state, solve the problem that broadcast receiver directly is provided with frequency and fine setting frequency down fast.
Can be understood as computer program to this method and realize through the control relevant hardware, be that we send out a flow chart of realizing below.
It is as shown in Figure 1,
A: program initialization;
B: whether button button, when button is not pressed, is in wait state always;
C: press duration, the record button is pressed duration, presses constantly from button, and button discharges constantly and ends; The record button is pressed duration, if pressing duration then gets into the D step less than T1, if press duration greater than T1 and less than T2; Then get into the E step,, then get into the F step if press duration greater than T2;
D: button is pressed duration less than the T1 execution in step, if button is not released in the time at T1, does not then carry out any operation; Return the C step; If button is released in the time at T1, carry out corresponding operating (concrete operations can be participated in top subordinate list) according to key-press status, described key-press status comprises general state; Length is pressed state, and overlength is pressed state;
E: button press duration more than or equal to T1 less than the T2 execution in step; If the time of pressing equals T1; Then key-press status is set to long by getting into the G step behind the state; If the time of pressing equals T1+NT3 (N is the self-heating number), then frequency steps further gets into the G step in the back, if the time of pressing belongs to other scopes and then directly gets into the G step;
F: button is pressed duration more than or equal to the T2 execution in step; If the time of pressing equals T2; Then key-press status is set to overlength and gets into the G step after by state; If the time of pressing equals T2+NT3 (N is the self-heating number), then frequency step M step back gets into the G step, if the time of pressing belongs to other scopes and then directly gets into the G step;
G: whether button discharges, if discharge into the B step, gets into the C step if not.
Need to prove; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these changes and distortion all should belong to the protection range of the appended claim of the present invention.
