Description of drawings

Accompanying drawing is the circuit theory diagrams of a kind of embodiment.L is a current transformer, is connected in the circuitry; J1-1 is connected on always stopping in the button circuit of original system.

Embodiment

Be further described with regard to its principle of work below in conjunction with accompanying drawing:

Transformer B connects the interchange end of rectifying block DZ, the dc output end that capacitor C 1 is connected in parallel on rectifying block DZ, and rechargeable battery DC connects diode D1 and resistance R 1 is formed power circuit; Capacitor C 2, C3 parallel voltage-stabilizing piece IC1 form mu balanced circuit; The data terminal of mobile module IC3 connects single-chip microcomputer IC2 as the signal transmitting and receiving circuit; The reset circuit of single-chip microcomputer IC2 is made up of capacitor C 4 resistance in series R, and crystal oscillator TT is the clock circuit of IC2; Single-chip microcomputer IC2 forms signal processing circuit; Sound circuit IC4 connects capacitor C 5 series connection loudspeaker LB and forms voice playing circuit; Optocoupler GB4 input end resistance in series R10, optocoupler GB4 output terminal resistance in series R9, the base stage of triode BG1, the collector connection relay J1 of triode BG1, diode D3 J1 in parallel forms the control executive circuit, and the normally closed contact of relay J 1 is connected on always stopping in the button circuit of original system; The signal end of infrared detection module M resistance in series R2, M connects triode BG2 base stage, BG2 collector and optocoupler GB1 and resistance R 3 member's detection circuits through capacitor C 6; Input end resistance in series R4, the R5 of optocoupler GB2, GB3 and original system air switch or A.C. contactor auxiliary contact J2, Jn are equipment work condition monitoring circuit, and this section circuit can increase a plurality of.Current transformer L series diode D2, capacitor C 7 adjustable resistance R6 in parallel, resistance R 7, R8 connect time base circuit IC5 (NE555) again and connect capacitor C 8 and optocoupler GB5 component devices overload detection circuit; It is the media wireless signal transmission that native system adopts GSM or CDMA.

Principle of work:

Transformer B is the power supply step-down, rectifying block DZ rectification, the direct current after the rectification, the one tunnel through resistance R 1 to rechargeable battery DC charging, another road via integrated regulator IC1 (7812) connect capacitor C 2, C3 forms the mu balanced circuit voltage stabilizing provides power supply to circuit.As the energy of rechargeable battery DC provides the energy through diode D1 to circuit when occurring having a power failure.

Power connection, the circuit operate as normal, original system air switch or A.C. contactor auxiliary contact J2, Jn are normally open, and equipment work condition monitoring circuit remains static, and optocoupler GB2, GB3 do not have electronegative potential output; Simultaneously, the output signal of current transformer L is less in the apparatus overload testing circuit, because time base circuit IC5 is operated in flip-flop states, so the IC5 output low level, the output terminal of optocoupler GB5 does not have electronegative potential output yet; At this moment the signal processing circuit of being made up of single-chip microcomputer IC2 etc. is not worked, voice playing circuit Triggerless and noiseless; As signal transmitting and receiving circuit mobile module IC3 do not have yet control and static.

During circuit working, no matter non-fault is arranged, as long as there is the people movable near switch board, then by the work of member's detection circuits such as infrared detection module M, triode BG2 conducting, optocoupler GB1 exports electronegative potential;

When circuit breaks down:

(1) lose as original system air switch tripping operation or A.C. contactor and make auxiliary contact J2, Jn closure, equipment work condition monitoring circuit start, optocoupler GB2, GB3 export electronegative potential;

(2) when current transformer L in the apparatus overload testing circuit detects electric current and is elevated to setting value, the duty of time base circuit IC5 changes the output high level, the output terminal output electronegative potential of optocoupler GB5;

At this moment the signal processing circuit of being made up of single-chip microcomputer IC2 etc. obtains alarm signal work, as people's activity is arranged near the device control equipment this moment, signal processing circuit switches to voice playing circuit with signal, triggers voice playing circuit and sends corresponding audio alert, reminds the staff in time to handle.As unmanned movable near this moment device control equipment, signal processing circuit switches to the signal transmitting and receiving circuit with signal, sends alerting signal by the signal transmitting and receiving circuit to staff's mobile phone, and shows phenomenon of the failure with short message mode.When if the staff finds that fault is serious and does not scurry the scene; at this moment the staff can utilize mobile phone to send control signal to native system; after system receives control signal; coupling GB4 input end obtains voltage and makes optocoupler GB4 conducting; triode BG1 conducting; relay J 1 adhesive is because the normally closed contact of relay J 1 is connected on always stopping in the button circuit of original system, so the control executive circuit can in time be shut down original system.
