First find the discontinuous time interval between the signal strings: The positive edge of the infrared signal will trigger the interruption of 8051. The interruption processing subroutine records the interval between each interruption. After dozens of interruptions, whichever is the largest, It is the discontinuous time interval between signal strings. In order to avoid misjudgment caused by noise interference, the maximum time interval between repeated occurrences is the discontinuous time interval. 2. Find the characteristic time interval of the infrared signal: Record the height of the second interruption interval Level time interval (or low level time interval), after dozens of interruptions, take repeaters to get a number of time intervals 取, take the shorter two, as and " The time interval of Γ is long; 3. The key code for memorizing the infrared signal: After obtaining the discontinuous time interval and characteristic time interval of the infrared signal, use the discontinuous time interval to detect the beginning of the signal string, and the time of "〇 " and " Γ The bit data of the signal is judged by the distance. After reading a series of signals, the bit digits are collected to form a key code. The same key is read for several times. The same key code is regarded as the correct code. 4. For signal learning, first use Micro Motion The time interval is used to judge, if it is unsuccessful, then the low-level time interval is used to interpret. The software design of this creation is composed of 5 parts: the main program (see Figure 7), two timing interruption subroutines (see Figure 3 and Figure I) , And two external interrupt subroutines (see Figures 5 and 6); the T0 timer is programmed to generate an interrupt every 0.05 seconds, and its interrupt subroutine performs the update of the electronic clock time. The time record is divided into seconds, minutes, Hours and days, with a week (7 days) as the cycle. In addition, the T0 interruption subroutine also checks whether the automatic opening time and automatic closing time of each channel have arrived.

Description of the invention (6) shown in the figure; T1 timer is programmed to generate an interrupt every 0.2 ms' The interrupt subroutine is used to calculate the trigger angle and The calculation of infrared time interval and trigger angle is used for power control and output power of four channels of AC power. It is eight segments, which is converted into 触发 with eight trigger angles, and the trigger angle count is increased by one each time when the next power segment is reached. When the next power segment is reached, those who set the power segment in each channel are turned on. The timing is interrupted and used to measure infrared The intermittent time interval and characteristic time interval are used to judge the end of the signal string and the end of the infrared signal. The flowchart is shown in Figure 4; INTO. The external interrupt is the infrared signal interrupt, and its interrupt subroutine is shown in the flowchart in Figure 5. It shows 'After entering the learning mode', this interruption subroutine 'determines the discontinuous time interval of infrared rays' at the 90th interruption. With the discontinuous time interval, the start of the signal string can be determined, and the number of signal strings can be calculated. Time, determine the characteristic time interval of the infrared signal. If the time interval of the birth time fails, change the learning method. The characteristic time interval is changed from a high level time interval to a low level time interval. After the characteristic time interval is obtained, that is, The data in the signal string can be determined and memorized. After the key code is collected completely or the 40-bit key code register is full, it is left to the main program to perform key processing. In addition, the sub program also checks whether the key has been pressed for too long. In order to re-enter the learning mode; the INT1 external interrupt is a zero-crossing signal interrupt. Its interrupt subroutine resets the timing of the trigger angle and opens the channel of full power, as shown in the threshold six. The main program first sets the interrupt mode. The interrupt right bits are INTO, T1, INTI, TO from high to low, then the main program sets the timer mode and starts the timer. TO adopts mode 1, which is a 16-bit timer, and T1 adopts mode 2 ', which is 8-bit timing. Device's, automatic loading function, the 8051 single chip only has I28 bytes of data memory, used in this program to store the on-off time and power of four channels: five key codes, electronic clock time, interrupt Time interval, characteristic time interval, signal string count, bit count, and other working variables, etc. After the main program starts the timer, reset these variables, then start the LCD display and set to the electronic clock display mode.
