Accompanying drawing explanation

Fig. 1 is frame assumption diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

As shown in Figure 1, Moltimode switched control circuit of the present utility model, include many switching power circuits, timing trigger circuit, single chip machine controlling circuit, gsm module circuit and relay drive circuit, the output signal of described many switching power circuits is transferred to single chip machine controlling circuit through timing trigger circuit, and the output signal of described single chip machine controlling circuit is sent to respectively gsm module circuit and relay drive circuit.

As shown in Figure 2, described many switch power supplies route voltage output end is connected to five push-button switch S1-S5 in parallel, this push-button switch S1-S5 is parallel with normal open switch K, be in series with illuminating lamp EL, the output of described push-button switch S1-S5 is connected to power transformer T, rectifier bridge stack UR and filtering capacitor C1 successively, described timing trigger circuit by time the basis set resistor R1, resistance R 2 and the capacitor C2 that become module I C and output thereof to connect form.

Switch on power, press after any push-button switch S1-S5, alternating current 220V voltage adds switch at winding two ends of power transformer T through this button, also illuminating lamp EL is lighted simultaneously, the 8V induced voltage producing in the secondary winding of power transformer is after rectifier bridge stack UR rectification, filtering capacitor C1 filtering, for the machine provides working power.

Owing to switching on moment, time the basis set capacitor C2 both end voltage that becomes module I C the 2nd pin output to connect can not suddenly change, time basis set become the 2nd pin of module I C and the 6th pin voltage lower than Vcc/2, time basis set become the 3rd pin output high level of module I C, the 24th pin I/O end that this signal inputs to 8031 single-chip microcomputer IC1 is also high level, after 8031 single-chip microcomputer IC1 internal processes judgements, divide two-way to send driving signal, first via output, the 8th pin output high level by 8031 single-chip microcomputer IC1, make photoelectrical coupler IC3 conducting, promote relay K adhesive, its normally open contact transfers normally closed connection load power source to, this push-button switch S1-S5 enters regularly self-locking state (still can make illuminating lamp EL maintaining lights after release button), along with time basis set become the charging of the capacitor C2 that module I C the 2nd pin output connects, time basis set become the 2nd pin of module I C and the 6th pin voltage constantly to rise, when bipod voltage rises to 2Vcc/3, (approximately 5 minutes), time basis set become circuit upset in module I C, its the 3rd pin becomes low level from high level, the 24th pin I/O end that this signal inputs to 8031 single-chip microcomputer IC1 is also high level, after 8031 single-chip microcomputer IC1 internal processes judgements, the 8th pin output low level of 8031 single-chip microcomputer IC1, make photoelectrical coupler IC3 cut-off, relay K discharges, cut off load power source, another road output, by the output of 8031 single-chip microcomputer IC1 and the input of gsm module IC2, connect to form GSM data transfer control circuit, 8031 single-chip microcomputer IC1 send driving signal to gsm module IC2, after the decoding of gsm module IC2 internal circuit, by base station network, reach and specify night shift room personnel mobile phone, send current on off state information, there is the function of the control of switch multipoint mode and teletransmission data.

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