In slowdown monitoring circuit: electrical equipment is normal in manager, load is less also there is no when short circuit, and distribution box is registered one's residence firewire in family
Insulating layer temperature is lower than 50 DEG C, and the firewire of registering one's residence of distribution box is close together in the side thermistor RT and family, this moment, thermistor
The resistance value of RT is higher in 10K or so, and the 12V power supply of the first battery G1 anode output is dropped through adjustable resistance RP1, thermistor RT
Enter the 0.7V starting voltage that voltage at NPN triode Q1 base stage is lower than NPN triode Q1 after pressure, NPN triode Q1, which is in, cuts
To state；Electrical equipment is abnormal in manager, load is excessive or when short circuit occurs, and distribution box firewire of registering one's residence is exhausted in family
Edge layer temperature can be higher than 50 DEG C, since the firewire of registering one's residence of distribution box in the side thermistor RT and family is close together, so this moment,
The resistance value of thermistor RT can be rapidly decreased to 4K or so, and this moment, the 12V power supply of the first battery G1 anode output is through adjustable electric
Enter voltage at NPN triode Q1 base stage after hindering RP1, thermistor RT decompression, the 0.7V higher than NPN triode Q1 originates electricity
Pressure, NPN triode Q1 its collector output low level in the conductive state enter the base stage of PNP triode Q2, PNP triode Q2
Its collector output high level enters 1 foot of signal input part of single chip circuit U1 after conducting.Single chip circuit U1 and wireless hair
In transmit-receive radio road U2: the high electricity of 2 foot of gas leakage signal input part input occurring after single chip circuit U1 work once electrified, either in family
1 foot input high level signal of electrical equipment fault-signal input terminal, single chip circuit U1 two-way power supply are defeated in ordinary mail number or family
Outlet 3 and 4 feet can export high level simultaneously and respectively enter relay K1, K2 cathode power supply input terminal (cathode of relay K1, K2
Communicated this moment with the first battery G1 cathode), then, relay K1, K2 respectively electric be attracted its control input contact and normally opened
Tip side is respectively closed；Since the signal of relay K1 control input tip side, normally opened contact end and radio transmitter U2 is defeated
Enter to hold two power contacts under first transmitting key SK of wireless transmission component to connect respectively through conducting wire, so this moment, wirelessly
Emitting module U2 can launch the wireless closure signal of the first via；Due to, relay K2 control input tip side, normally opened contact end and
Two power contacts are connected through conducting wire under the experiment triggering key S of earth leakage protective device U3 in distribution box in family, so this moment, electric leakage
Two power contacts can be connected under the experiment triggering key S of protector U3, in turn, in itself function of earth leakage protective device U3
Under, earth leakage protective device U3 trips, and the whole power loss of electrical equipment meeting no longer work in subsequent family, in this way, it is therefore prevented that electricity consumption is set in family
Caused fire and electrical equipment work on and cause the extension of accident after standby load is excessive or short circuit.
Shown in Fig. 4, in wireless receiving circuit, short message alarm module U5, buzzer B and electromagnetic gas valve DC: being sent out in manager
The excessive short circuit of electrical equipment load occurs for raw gas leakage, and wireless transmission component U2 launches the wireless closure signal of the first via
Afterwards, this moment, wireless receiving component U4 can receive the wireless closure signal of the first via, and then, wireless receiving component U4 is inside it
Under circuit function, first 4 foot of output end can export high level and enter the one end resistance R4, the high electricity after resistance R4 is depressured current limliting
The flat base stage into NPN triode Q5, then, NPN triode Q5 conducting collector output low level enter relay K3 cathode
3 foot of power input and short message alarm module U5 signal input part, relay K3(relay K3 cathode power supply input terminal is this moment
Communicated with the second battery G2 anode) obtain its control input contact of electric actuation and normally opened contact closure；Due to short message alarm module
U5 positive and negative polarities are communicated with the second battery G2 positive and negative polarities respectively this moment, NPN triode Q5 collector and short message alarm module
3 foot of U5 signal input part is connected through conducting wire, so, NPN triode Q5 collector output low level enters short message alarm module U5
After 3 foot of signal input part, short message alarm module U5 under circuit function, can automatically send out a short message to user inside it
And the mobile phone of property management personnel at one's side, short message content is " having fire behavior ", after the user except being in is connected to short message, so that it may
It is disposed in going home in a hurry in time, property management personnel can be disposed to scene as early as possible after being connected to short message, prevent fault spread
Change；Due to, relay K3 normally opened contact end is connected with buzzer B and electromagnetic gas valve DC cathode power supply input terminal through conducting wire, the
Two battery G2 cathode are connected with electromagnetic gas valve DC, buzzer B negative power supply input terminal through conducting wire, so, relay K3(relay
Device K3 control input tip side is communicated with the second battery G2 anode this moment) obtain its control input contact of electric actuation and normally opened contact
After closure, buzzer B can be made a sound, and the user and neighbouring property management personnel aligned at home prompts, electricity
Magnetism valve DC meeting its inner spool of work once electrified is closed, and combustion gas no longer exports, and prevents the generation for leading to fire because of gas leakage
And accident is magnified after fire occurs.When gas leakage or excessive power supply line's load has just occurred in the utility model manager,
Under interlock circuit effect, buzzer B not only live can issue alarm sound and give user and neighbouring property at the scene
Administrative staff's prompt, moreover it is possible to notify user to be outside disposed in going home in a hurry in time by short message mode, and object can be given
Industry administrative staff send short message, and property management personnel can be disposed to scene as early as possible after being connected to short message, and can also be automatically closed
Main gas valve and total lock of powering in family, thus can effectively prevent the generation of fire, and can effectively disconnect fire when fire occurs
Source, as far as possible reduction fire are lost to user's bring.Based on above-mentioned, so the application prospect that the utility model has had.
