Detailed ways

In Fig. 1, a new type of LED intelligent control electrical socket includes a main control module 1, a wireless receiving module 2, a relay module 3, an LED display module 4, an A/D conversion module 5, and a voltage sensor 6, and is characterized in that: The main control module 1 is respectively connected with the wireless receiving module 2 , the relay module 3 , the LED display module 4 , and the A/D conversion module 5 , and the A/D conversion module 5 is also connected with the voltage sensor 6 . When the wireless receiving module 2 receives the command, it sends it to the main control module 2 for decoding, and the main control module 2 realizes remote operations such as timing switch or immediate switch on the single or multiple sockets through the relay module 3, and the voltage sensor 6 measures The analog signal obtained from the mains is converted into a digital quantity by the A/D conversion module 5, and sent to the main control module 1, and the LED display module 4 displays the current voltage value, time, switch status of each socket, and the countdown of each channel on or off Display of information such as time.

The main control module 1 uses AT89S52 single-chip microcomputer of Atmel Company as the control unit, and the wireless receiving module 2 uses PT2272 and PT2262 paired encoding and decoding chips. Since the main control module 1 interferes a lot with the wireless receiving module 2, PC817 is used here for optocoupler isolation. When PT2272 receives valid encoded data, the VT terminal will output a high level. Utilizing this feature, the external interrupt trigger mode of the main control module 1 can be set as a falling edge trigger, and the external interrupt of the main control module 1 can be driven by the output of the VT terminal when the wireless receiving module 2 receives valid data. In the external interrupt processing program, the 4-bit data sent over, continuous reception of four 4-bit data is a complete transmission process. The main control module 1 obtains the corresponding instruction and then performs timing through the clock chip, and performs corresponding power on and off for the relay module 3, and then controls the power on and off of the socket. The maximum current of the relay module 3 is 3A, and the maximum withstand voltage is 450V. What voltage sensor 6 adopts is resistance divider mode, measures mains electricity analog signal, is converted by A/D conversion module 5, and A/D conversion module 5 adopts 12 successive approximation A/D converters, and its conversion speed is fast , 12-bit precision, a conversion time of 25 s, conversion rate of 40MSPS, on-chip three-state output latch buffer, full 8-bit or 16-bit microprocessor interface, 250 s bus read time, and microprocessor interface Simple, the nonlinear error is less than ± 1/2LBS or ± 1LBS, after conversion, it is sent to the main control module and displayed through the LED display module 4.
