1, remote controller is emitted as the infrared signal of shutdown command, is transferred to single-chip microcomputer Ua and identifies the control command into shutdown after infrared receiving tube IR1 receiving demodulation.The RA1 pin of single-chip microcomputer Ua is waited for the detection signal PD that current detection module 102 is exported.Meanwhile, single-chip microcomputer Ua output control command is transmitted to electrical equipment by infrared transmitting tube Db, makes electrical equipment in holding state.
2, under holding state, the upper no current of the first current detecting end L1 and the second current detecting end L2 flows through, when current sensor chip U3 detects its IP+ end, IP-end for low level, the voltage signal of output low level, amplify successively, after comparison, rectification, detection the detection signal PD of output low level to the single-chip microcomputer Ua of infrared control device 20.
3, single-chip microcomputer Ua judges that electrical equipment is in holding state, starts its internal timer start timing, and after timing time reaches, postpone after Preset Time (as 15 minutes), the switching signal SW of output low level is to switch control module 101.
4, low level switching signal SW controls the first triode Q1 cut-off, does not have electric current to flow through its first terminal 3 and the second terminal 4 are disconnected between the anode 1 of optocoupler controllable silicon U1 and negative electrode 2.In the 4th resistance R 4 and the 5th resistance R 5, no current flows through, the first anode A1 of bidirectional triode thyristor U2 and second plate A2 blocking-up, and alternating current 220VAC_in cannot, from power output interface J2 output, be equivalent to cut off the power supply of electrical equipment, thereby reduce stand-by power consumption.When powered-down, LED light Da is in normal bright state.
Should be understood that, in single-chip microcomputer Ua timing course, if detection signal PD becomes high level, judge not only in running order (this for user's shutdown after but also the situation of start) of electrical equipment, now timer quits work and by timing zero clearing.Owing to also not cutting off the electricity supply, the electrical equipment state of can resuming work.The present embodiment is the switching signal SW powered-down of ability output low level after detection signal PD keeps low level to exceed timing time only, produces unnecessary power consumption to avoid electrical equipment energising, power-off frequently to switch, and extends the useful life of switch control module 101.
Two, when electrical equipment is in off-mode, need to start shooting time.
1, the infrared signal of remote controller transmitting start-up command, is transferred to single-chip microcomputer Ua and is identified the control command into start after infrared receiving tube IR1 receiving demodulation.The RA5 of single-chip microcomputer Ua exports the switching signal SW of high level immediately to switch control module 101.
2, the switching signal SW of high level controls the first triode Q1 conducting, produces constant electric current its first terminal 3 is connected with the second terminal 4 between the anode 1 of optocoupler controllable silicon U1 and negative electrode 2.Voltage increases in the 4th resistance R 4 and the 5th resistance R 5 makes first anode A1 and the second plate A2 conducting of bidirectional triode thyristor U2, and alternating current 220VAC_in, from power output interface J2 output, gives electric power supply.
3, on the first current detecting end L1 and the second current detecting end L2, have electric current to flow through, when current sensor chip U3 detects its IP+ end, IP-end for high level, the detection signal PD of output high level is to single-chip microcomputer Ua.
4, single-chip microcomputer Ua judges that according to the detection signal PD of high level the supply access between electrical equipment and power interface is connected.Single-chip microcomputer Ua output control command is transmitted to electrical equipment by infrared transmitting tube Db, makes electrical equipment start, enters operating state.When turn-on power, LED light Da is in extinguishing state.
One of improvement of the economizing switch controlling device that the present embodiment provides is also, has greatly reduced power consumption.According to side circuit, test show that the maximum stand-by power consumption of each module comprises: supply module is 30mW, and infrared control device is 2.8mW(single-chip microcomputer)+6mW(infrared receiving/transmission), current detection module is 52mW, switch control module is 2mW.Total consumed power under holding state is less than 0.1W.If economizing switch controlling device is worked always, the electric weight that one year consumes is: 0.1W*24h*365=876Wh=0.876 degree; That is to say, the electric weight that economizing switch controlling device consumes for a year is less than 1 degree, is almost " 0 " power consumption.
In sum, the economizing switch controlling device that the utility model provides, in the time that needs are started shooting, according to the supply access between the switching signal conducting electrical equipment of the first level and power interface, gives electric power supply by switch control module.In the time that current detection module detects electrical equipment in holding state, output detection signal is to infrared control device, the switching signal control lag that infrared control device postpones to export after Preset Time second electrical level closes the supply access between circuit breaker and power interface, stops power supply, to reduce stand-by power consumption.Because described switch control module adopts solid state control circuit structure, there is the advantages such as safer, life-span length, noise-less pollution, electromagnetic radiation are little than common on the market electromagnetic relay control mode.Meanwhile, the circuit design of economizing switch controlling device and the model of electronic device select to make the electric weight that one year consumes to be less than 1 degree, not only self energy consumption low, also greatly reduce standby energy consumption by powered-down after standby.
Be understandable that; for those of ordinary skills; can be equal to and replace or change according to the design of the technical solution of the utility model and utility model thereof, and all these changes or for the protection range that all should belong to the appended claim of the utility model.
