Device is switched.
Embodiment
When single chip circuit power-off is stopped, long-press K1 (more than 3 seconds), the VCC of battery P1 and single chip circuit passes through
Key switch K1 is connected, single-chip microcomputer energization work, while single-chip microcomputer is judged whether by I/O mouthfuls of P2.5 states or on-off times
Meet compressor start up condition (more than 3 seconds K1 turn-on times of switch), I/O mouthfuls of P3.2 is set low level when eligible (electric on single-chip microcomputer
Original state：I/O mouthfuls of all pins are high level), make relay (the 3 of relay and 4 connect) in an ON state, release
Put K1 and still connect battery and power, single chip circuit start work；I/O mouthfuls of P3.2 are still high level, relay when ineligible
It is off (the 3 of relay and 4 disconnect), release K1 is to disconnect battery to power, single chip circuit shutdown.
After single chip circuit work, relay in an ON state when (the 3 of relay and 4 connection), then long-press K1 (3 seconds
More than), single-chip microcomputer judges whether to meet cut-off condition (more than 3 seconds K1 turn-on times of switch) simultaneously by I/O mouthfuls of P2.5 states,
I/O mouthfuls of P3.2 are made to put high level when eligible, relay is off after (the 3 of relay and 4 disconnect), release K1 i.e.
Disconnect battery to power, single chip circuit shutdown；I/O mouthfuls of P3.2 are still low level when ineligible, and relay remains up shape
Still battery is kept to power after state (the 3 of relay and 4 connect), release K1, single chip circuit continues powered operation.
After the completion of single chip circuit task, software control makes I/O mouthfuls of P3.2 put high level, and relay becomes to disconnect shape
State (the 3 of relay and 4 disconnect), that is, disconnect battery and power, single chip circuit shutdown.
The present invention is described in further details below.
A kind of power switch circuit of cyclelog, including battery, relay, key switch K1, and resistance R1, resistance
R2, resistance R3, and single-chip microcomputer, relay include relay coil A1 and relay switch K2.Characterized in that, battery is just
Pole connection resistance R1 one end, the resistance R1 other end connects one end of relay U1 coils, the relay coil A1 other end
Resistance R3 one end is connected, the resistance R3 other end connects the negative pole of battery, and the relay coil A1 other end connects list simultaneously
The port P3.2 of piece machine；
The positive pole of battery also connects relay switch K2 one end and key switch K1 No. 1 end, relay switch simultaneously
