Carefully state the structure and the course of work of this embodiment of the utility model below in conjunction with Fig. 4,5,6.
Main controller is the core control section of native system, it is the part of sending of control signal, with reference to Fig. 4, main controller comprises AT89C51 microprocessor, DS12887 calendar and clock chip, MAX813L supervisory circuit, LED display circuit, several parts such as U, V, W three-phase carrier signal radiating circuit.The AT89C51 microprocessor is the core processor of main controller, its embedded program that weaves and follow procedure send respective logic and digital signal, pass through in advance to press the key assignments illumination period according to the daily schedule, the AT89C51 microprocessor will cut out at needs according to the illumination period that configures the moment of illumination, produce corresponding logical signal, control U, V, W three-phase carrier signal radiating circuit send the signal of closing illumination simultaneously.The signal of closing illumination that the carrier signal radiating circuit sends is sent to each iversion controller through power line.The transmitting range farthest of carrier signal radiating circuit can reach 500 meters, can reach one 10 each room in the floor room fully.
AT89C51 microprocessor in the main controller, what select for use is the enhancement mode 8-bit microprocessor that atmel corp produces, electricity can be wiped EEPROM and be used for depositing the user program that weaves in the built-in 4K sheet.The economize on electricity of present embodiment require be " at noon, afternoon, night after class and classes are over that the time sends closes illumination sign and turn-off power supply in each classroom.When if the indoor people of having still needs electricity consumption, can reclose power supply by the switch on the iversion controller of installing in the classroom.So just, can prevent indoor unmanned altar lamp phenomenon ".
Can require establishment corresponding clock program and logic determines program according to above-mentioned economize on electricity during use, and program is written to after the compiling debugging is good in the sheet of AT89C51 among the EEPROM.AT89C51 will be according to this program, by clock DS12887 chip preset time, query time, and follow procedure requires to close at needs the moment of mains lighting supply, produce corresponding logic level by P1.5, P1.4, P1.3 mouth, thereby control U, V, W three-phase carrier signal radiating circuit send the signal of closing illumination.
The DS12887 calendar clock chip is the calendar clock chip that the design of U.S. DALLS company is produced, and has advantages such as little power consumption, peripheral interface is simple, precision is high, working stability is reliable.The data address multiplex bus AD0～AD7 of DS12887 clock chip and the P0 of AT89C51 link to each other; Chip selection signal CS links to each other with the P2.7 of AT89C51; Interrupt request singal IRQ links to each other with the P3.3 of AT89C51, in order to interrupt signal to be provided; Write signal R/W links to each other with the WR of AT89C51; Read signal DS links to each other with the RD of AT89C51; Address latch signal ALE links to each other with the ALE of AT89C51, and the least-significant byte address latch signal is provided.
Time display circuit utilizes serial port RXT, the TXD of AT89C51 and 8 serial-in parallel-out register 74LS164 chips of P1.7 control, and drives 8 LED and realize, can show normally to move and time of setting usefulness " day, the moon, time, branch ".This circuit uses less led driver spare, thereby cost is very low.
The operation principle of MAX813L supervisory circuit is: when single chip computer AT 89C51 works, because there are various interference in circuit, may cause that the race of program flies, cause the abnormal running of deadlock or program, must in time recover, in order to avoid cause damage.When program is normally moved, regularly send a pulse and make the zero clearing of monitoring chip MAX813L inside counting device by the P1.6 mouth of AT89C51, if program fleet, then the P1.6 mouth of AT89C51 can not send pulse to MAX813L, MAX813L inside counting device can be counted full of overflowing always, its RESET mouth sends reset signal to AT89C51, AT89C51 is resetted, restart working procedure.
The circuit diagram of carrier signal radiating circuit is with reference to Fig. 5, the carrier signal radiating circuit is made up of electronic switch and the middle all transformer B1 that tone decoder NE56, photoelectrical coupler N35 and triode T2 form, and middle all transformers are connected with power line through inductor L1, L2, capacitor C1, C2.Control the connection of U, V, each phase carrier transmit circuit of W respectively by P1.5, P1.4, the P1.3 mouth of AT89C51, the structure of each phase carrier transmit circuit is identical, be that core is formed the carrier oscillation generator all, transfer resistance R W1 can change carrier frequency with tone decoder NE56 with " phase-locked loop " circuit.Its operation principle is as follows: when P1.5, P1.4, P1.3 become 0 by 1, photoelectrical coupler N35 conducting, triode T2 conducting, " 7 " pin of NE56 gets electric, and middle all transformer B1 get, the NE56 starting oscillation, its frequency of oscillation can be adjusted by RW1, and oscillator signal is through the output of NE56 " 5 " pin, again after the tuning amplification of T1, B1, be coupled on the 220V power line through L1 and C1, L2 and C2, this is the carrier signal of closing illumination that main controller sends.Two inductance of L1, L2 are in order to isolate the influence of power line to resonant tank.
When main controller needs to send " cutting out illumination " signal, AT89C51 sends " writing 1 " order to its port P1.5, P1.4, P1.3 mouth earlier, make these three port signals become 0 by 1, then photoelectrical coupler N35 conducting, the electronic switch conducting that N35 and triode T2 form, " 7 " pin of NE56 receives+12V on, so NE56 must establish beginning work by cable, by " 5 " pin outgoing carrier signal of NE56,, and be coupled on the 220V power line through L1, C1, L2, C2 through the tuning amplification of T1, B1.
Iversion controller is installed in each classroom, when iversion controller receives " closing illumination " signal that the carrier signal radiating circuit sends, turn-offs mains lighting supply by the secondary switching circuit in the iversion controller.
