Accompanying drawing 1 is the flow chart that radio buttons of the present invention arranges frequency approach.
Embodiment
In order to allow those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the present invention is further elaborated.
A kind of radio buttons arranges frequency approach, comprises the following steps;
Wait for that button presses step, when button is not pressed time, be in wait state, the record button risen when button is pressed time below entering presses duration step always;
Record button presses duration, and press the moment from button and only play the button release moment, record button presses duration, as long as button does not discharge, clock and just do not stop, after button release, clock clearing, next time time in, and the record of button duration can be realized by timer.T1, T2 are that button presses duration and T1<T2.
Button is pressed duration and is less than T1 execution step: if button is not released within the T1 time, then do not perform any operation, if button is released within the T1 time, corresponding operating is performed according to key-press status, described key-press status comprises the general state pressing down the next radio station of automatic search, presses down frequency steps further normal by state, and button presses the overlength of frequency step M step by state, described M is the natural number of 5-15, and we preferred M is 10.
Button press duration be more than or equal to T1 be less than T2 perform step, key-press status is set to normal by state at T1 time point, light every a time interval T3 frequency steps further from the T1 time, if during this period of time button release, jump to described wait button and press step;
Button is pressed duration and is more than or equal to T2 execution step, key-press status is set to extraordinary by state at T2 time point, light from the T2 time and walk every a time interval T4 frequency step M, if during this period of time button release, jump to described wait button and press step.
Button press duration be less than T1 perform step, button press duration be more than or equal to T1 be less than T2 perform step, button press duration be more than or equal to T2 perform step.The execution of these three steps be with button according to the duration for order, the execution of step is above the necessary condition of the execution of step below, that is have step below must have step above, but the execution of preceding step must not cause the execution of later step.Button continue according to, then these steps are carried out always in chronological order, once button release, no matter go to any one step in these three steps, this step stop.
The time span of both T3 and T4 does not have inevitable contacting, but the requirement to software and hardware in order to the simple of process and reduction, so preferably time span T3 equals T4.
After release button, if do not push button again within the T5 time, key-press status reverts to general state, this technical characteristic makes this method can as spring uniform quality, no matter key-press status arrange long by state or overlength by state, can general state be got back to through the T5 time, because general state a kind of state that to be button the most frequently used, can reduce the step that User Status switches by this method, this method operation easily.Also make this method have better robustness by this technical characteristic, when user operation mistake time, or do not know that how to operate, as long as can general state be got back to through the T5 time, can resume operations, and operation above, operation below can not be affected.As for the setting of T5 time length, do not limit in theory, but should not be too short in substantial manipulation, be preferably greater than 5 seconds.
Step direction can be low frequency to high-frequency, and the method for the application is applicable to channel selection direction from low frequency to high-frequency.From low frequency to high-frequency, when frequency goes to highest frequency, its next point is turned back to low-limit frequency.
Step direction can be high-frequency to low frequency, and the method for the application is applicable to channel selection direction from high-frequency to low frequency.From high-frequency to low frequency, when frequency goes to low-limit frequency, its next point is turned back to highest frequency.
The broadcast receiver of this method is used preferably to have two buttons, upwards search the button (step direction can be low frequency to high-frequency) of element and the button (step direction can be high-frequency to low frequency) of a search downwards for one, by utilizing this two buttons, not only can realize upwards (downwards) and automatically search plain radio station, conveniently upwards (downwards) stepping can also be realized frequency of radio station is set, and upwards (downwards) quick-setting frequency of radio station.
Described step frequency is exactly minimum adjusting frequency.The selection frequency of such as modulating FM is 87.5MHz ~ 108MHz, just can there is a radio station every 0.1MHz, and the step frequency of modulating FM is 0.1MH.And the selection frequency of amplitude modulation AM is at 531 ~ 1096 kHz, just can have a radio station every 9KHz, that is the step frequency of AM is 9KHz.Described step is further just on step direction, and advance a step frequency.
Application-defined button general state is our a kind of function common in other similar-type products, be click, unclamp hand, equipment is automatically from low frequency point to high-frequency point (or from high-frequency point to low frequency point), with step frequency, (FM is 0.1MHz, AM is 9KHz) search for radio station, when meeting search condition, just play this radio station.
In order to realize the several functions of button, the application is defined the state that button is pressed, and according to pressing duration, defines three states, i.e. general states, and long by state, overlength is by state, as shown in the table:
| Key-press status | Condition | State characteristic |
| General state | Release in the T1 time after pushing button | Often press the next radio station of one-touch automatic search |
| Long by state | Do not discharge in the T1 time after pushing button, and press duration not more than T2 | Often by stepping frequency, if continue in this condition to press, every T3, stepping frequency |
| Overlength is by state | Push button duration more than T2, and from being no more than T3 by doing button for the last time | Often by a stepping M frequency, if continue in this condition to press, every T4, a stepping M frequency |
Button in the application have long by with overlength by state, the problem of frequency and fine setting frequency is directly set under solving broadcast receiver fast.
This method can be understood as computer program by controlling corresponding hardware implementing, here is that we send out the flow chart realized.
As shown in Figure 1,
A: program initialization;
B: button whether button, is in wait state when button is not pressed time always;
C: press duration, record button presses duration, and from button presses the moment, the button release moment is only, record button presses duration, if press duration to be less than T1, enters D step, is greater than T1 if press duration and is less than T2, then enter E step, if press duration to be greater than T2, then enter F step;
D: button is pressed duration and is less than T1 execution step, if button is not released within the T1 time, then do not perform any operation, return step C, if button is released within the T1 time, perform corresponding operating (concrete operations can participate in subordinate list above) according to key-press status, described key-press status comprises general state, long by state, overlength is by state;
E: button press duration be more than or equal to T1 be less than T2 perform step, if the time of pressing equals T1, then key-press status is set to long by entering G step after state, if it is self-heating number that the time of pressing equals T1+NT3(N), then frequency steps further after enter G step, if the time of pressing belongs to other scopes, directly enter G step;
F: button is pressed duration and is more than or equal to T2 execution step, if the time of pressing equals T2, then key-press status is set to overlength by entering G step after state, if it is self-heating number that the time of pressing equals T2+NT3(N), then enter G step after frequency step M step, if the time of pressing belongs to other scopes, directly enter G step;
G: whether button discharges, if discharge into step B, enters step C if not.
It should be noted that; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change and are out of shape the protection range that all should belong to the claim appended by the present invention.
