Embodiment

As shown in Figure 1 and Figure 2, a kind of generation comprehensive control system of the present utility model, comprise oil level detection circuit 1, line voltage testing circuit 2 and single chip machine controlling circuit 3, the output signal of described oil level detection circuit 1 sends to circuits for triggering 11, the output signal of circuits for triggering 11 and line voltage testing circuit 2 transfers to single chip machine controlling circuit 3, connects engine start circuit 31 and wireless transceiver circuit 32 by single chip machine controlling circuit 3 control outputs.

Described line voltage testing circuit 2 is made of the output connection transformer BL in AC220V loop, when thermoelectricity L1, zero line N constitute the AC220V loop, output 2.2V ac voltage signal, with output in 100: 1, this signal is through diode D1 rectification, electric capacity 1C1 filtering, resistance 1R1 current limliting, adjust adjustable resistance W2 and be used for check and correction and the linear output of input voltage, the 32nd pin I/O end that this voltage signal is input to single-chip microcomputer IC1 is high level state, after single-chip microcomputer IC1 internal processes is judged, do not send control signal.When mains failure, when transformer BT secondary output voltage is 0V, this signal is input to single-chip microcomputer IC1 the 32nd pin I/O end and is low level state, after single-chip microcomputer IC1 internal processes is judged, by the 21st pin output high level signal of single-chip microcomputer IC1, through resistance R 6 current limlitings, make triode Q2 conducting, relay contact J1-1 provides initiating signal by transferring normally closed point normal battle to generator, generator begins starting-generating, realizes that the automatic generator starting-generating powers to the load.When civil power restores electricity again, the 32nd pin I/O end of single-chip microcomputer IC1 is high level state, after single-chip microcomputer IC1 internal processes is judged, the 21st pin output high level signal by single-chip microcomputer IC1, make triode Q2 conducting once more, relay contact J1-1 provides stop signal by transferring normally closed point normal battle to generator.(generator starting signal or stopping signal only need provide normally closed some signal, connect the starting down of triggering state, connect and trigger flame-out the shutdown.)

Described oil level detection circuit 1 is made of lack of water point exploring electrode C, low water level point exploring electrode B, the water exploring electrode A that works to the last minute, when the oil drum oil level is lower than low water level point exploring electrode B point, the 2nd pin of NE555 time-base circuit U1 is a low level by resistance R 1 ground connection, NE555 time-base circuit U1 is high level output, this signal is input to the 34th pin I/O end of single-chip microcomputer IC1, after single-chip microcomputer IC1 internal processes is judged, do not send control signal.When the oil drum oil level is low to moderate lack of water point exploring electrode C point; the water about hundreds of ohm of the equivalent resistance resistance in the oil drum that exploring electrode A point and lack of water point exploring electrode C order of working to the last minute; the dividing potential drop effect of it and resistance R 2 makes the 6th pin level of NE555 time-base circuit U1 be higher than 2/3VDD; then NE555 time-base circuit U1 is in reset mode; the 3rd pin of NE555 time-base circuit U1 is low level state; after single-chip microcomputer IC1 internal processes is judged; after the judgement of single-chip microcomputer IC1 internal processes; send control signal; the high potential signal of being exported by the 26th pin I/O mouth of single-chip microcomputer IC1 makes triode Q1 conducting through resistance R 7; be input to the 2nd pin of FDD-5 transmitter module IC3; and deliver to its 3rd pin CP modulation signal input end; high-frequency signal to emission is modulated; the TX antenna is promptly launched modulated frequency electromagnetic waves to JDD-5 receiver module IC4; the 4th pin CPA audio signal output end of JDD-5 receiver module IC4 directly drives common electrical dynamic formula loud speaker Y sounding; its the 2nd pin data output end output high level makes LED 1 get electroluminescence simultaneously; expression receives the alarm signal of extension set; the oil drum oil level is on the low side please the operator on duty in time to refuel, and avoids the generator oil starvation and shuts down.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
