Embodiment
Below in conjunction with an accompanying drawing and a preferred embodiment the technical solution of the utility model is further described.
As Fig. 1; this infrared remote coding smart decoder comprises MCU, is arranged at some registers, infrared remote receiver, display, pilot lamp and hummer among the MCU; the some known code types of described register-stored; described MCU will be compared with setting sign indicating number type by the test patterns type that infrared remote receiver receives; determine whether the test patterns type belongs to the sign indicating number type of setting; if; then the information with the test patterns type shows on display; the different sound of buzzing is to show the comparative result correctness, and the functional indicator light indication is normal or unusual.
Because a frame sign indicating number code structure of infrared coding comprises preamble code, user code, numeric data code, fixed code, space code, parity code, end code etc. partly constitute, and for example, typical case 6122 sign indicating number type is as shown in Figure 4.Because the sign indicating number type is of different types, the sign indicating number type that has is to be made of preamble code, user code and numeric data code, and the sign indicating number type that has only is made of user code and numeric data code etc.
Difference according to code structure, the utility model is set some special-purpose registers in single-chip microcomputer, the preamble code of different sign indicating number types, user code, numeric data codes etc. store respectively according to a definite sequence, and set corresponding bit width and tolerance widths etc. and corresponding addressing mode;
The waveform that infrared remote receiver receives mainly is made up of a series of high-low level.In order to reach high precision, used two timers 0 and 1 during the test level width, and be aided with interruption.As shown in Figure 2, when first rising edge arrives, start timer 0 when first negative edge arrives, enter external interrupt program 0, timer 0 cuts out, and deposit timing value in corresponding registers.Start timer 1 record low level width simultaneously.Come then at second rising edge, enter external interrupt program 1, timer 1 cuts out, and deposit timing value in corresponding registers.Start timer 0 simultaneously, so go round and begin again, know all high-low levels of a frame sign indicating number are all noted.When receiving a frame sign indicating number type, can preserve it by program setting, then and the sign indicating number type of having stored before according to correlation method, screen comparison one by one.Further say, at first primary height (low) level of a frame sign indicating number that receives is carried out bit width relatively, according to program setting, it is similar to filter out its first with those yards type first, then to the 3rd of its second .. .... last position compares one by one, and then by comparing the figure place of one frame sign indicating number, code structure etc. are final confirms whether it is present in the row of having deposited yard type and specifically belongs to which kind of yard type.If through corresponding comparison, find that it is to have deposited a kind of in yard type, then by program setting the sign indicating number type classification of a frame sign indicating number of this reception, user code, numeric data code etc. (sexadecimal or scale-of-two) as requested show at display module respectively.If through comparison, find that it is not to have deposited a kind of in yard type, does not do any operation.
