Lighthouses and large storage sites generally use lighthouse lighting. In the past, lighthouses were mostly powered by power distribution room power control or single lighthouse manual operation. The technical performance and economic indicators of this method are very low. The inconvenient lighting dispatch management and energy-saving controller are equipped with a photosensitive sensor interface, which can control the opening and closing of the illumination by the light intensity. In addition, the remote control has a timing menu, which can be turned on and off according to the set time.
The main core of the remote control adopts Motorola's 8-bit single-chip MCHC705B16, which has 352bRAM, 1skbOTP, 255bEZPROM, 32 bidirectional 1/0, multi-function 16-bit timer. The EZPROM of the MCU ensures that the remote controller does not lose the parameters when the battery is insufficient and the battery is replaced. Its multi-bit 1/0 port and powerful driving capability greatly simplify the design of the hardware circuit. The peripheral hardware circuit mainly includes: the system uses hardware coding, the encoder uses the special chip HT-12E, and the line is connected with the PA port of the single chip microcomputer. According to this connection method, the total number of codes can be 256, that is, the remote controller can control 256 terminals.
The working principle is as follows: when the MCU outputs a start signal (active low) via the PC, the transistor T1 is turned on, triggering the thyristor SCR, and the RF transmitter is powered, and the AO-A7 forms a specific code according to the received signal. The function of the pulse from the execution terminal circuit to execute the terminal is to receive the RF signal from the remote controller. After decoding, the RF receiver head is matched with the RF transmitter head. The decoder uses the HT-12F with the encoder, and its AO-A7 address. The line is connected to the 8-bit code switch to form different address codes. When the address code of the decoder is consistent with the code transmitted by the remote controller, the VT port of the decoder outputs a signal, and the signal controls the output of the trigger CD4013, so that the trigger each After receiving the signal, the level of the output port QZ is inverted once, and the opening and closing of the relay J is controlled by controlling the conduction and the off of the TZ.
Software design remote control software is mainly to achieve menu function operation and interrupt processing, remote control software main program flow chart program initialization includes 10 port address code storage unit, time display single interrupt setting unit and menu and PSPICE software It is proved that the power factor of B00ST active positive circuit is less than 1, and the ultimate power is saved by constructing the simulation circuit.
