Background technology

The utility application " the household electrical appliance automation socket of powered battery, sensor management " of Patent Office of contemporaneity submission State Intellectual Property Office examination as working power, has proposed a kind of technical scheme of using transducer independently to control general household electrical appliance operation with battery pack.

Summary of the invention

The purpose of the utility model is to provide a kind of household electrical appliance automation socket of sensor management; It adopts D.C. regulated power supply to make the work power supply; With sensor management No. one household electrical appliance, said transducer comprises Switch-Output Type, level output type and pulse output type.

The utility model solves the technical scheme that its technical problem adopted: it is made up of sensor terminals S+, sensor terminals S-, the monostable circuit that can heavily trigger, ac solid relay and drive circuit thereof, ac solid relay output circuit, hand switch K and D.C. regulated power supply; Wherein, The monostable circuit that can heavily trigger combines timing resistor, timing capacitor to form by a monostable flipflop CD4098; Its rising edge trigger end is connected with a pull down resistor and sensor terminals S+; Its trailing edge trigger end is connected with a pull down resistor and sensor terminals S-; The output of the monostable circuit that triggers as this Lu Kechong after isolation resistance of its output Q series connection, the other end of said sensor terminals S+ and sensor terminals S-is all received the positive pole of working power; Ac solid relay and drive circuit thereof comprise an ac solid relay, a light-emitting diode, a triode, a pull down resistor and a base resistance; Wherein, One end of said two resistance all is connected to the base stage of triode; The other end of said base resistance is connected to the output of the monostable circuit that can heavily trigger, and the positive and negative input of light-emitting diode, ac solid relay, the collector electrode of triode and emitter thereof and working power are formed series loop; The ac solid relay output circuit comprises a piezo-resistance, a fuse and a socket; Wherein, Piezo-resistance is parallelly connected with two controlled outputs of ac solid relay; A controlled output of ac solid relay is received the L utmost point of socket; Its another controlled output is connected to the phase line (L line) of supply main through fuse, and the N utmost point of socket is connected to the working zero line (N line) of supply main, and its PE utmost point is connected to the protection connecting to neutral line (PE line) of supply main; The end of hand switch K is connected to the output of the monostable circuit that can heavily trigger, and its other end is connected to the positive pole of working power.The utility model is characterized in that: said D.C. regulated power supply is made up of power transformer, current rectifying and wave filtering circuit and voltage stabilizing circuit; Phase line (L line) that its two ac input ends are connected respectively to civil power and working zero line (N line), its two outputs are respectively as the positive pole and the negative pole of the working power of this device.

The incident that the utility model uses sensor monitors to be concerned about; This device of output signal triggering that the sensor sensing incident is produced moves; Cause its socket electrifying; Thereby make the electrical equipment and the civil power that are connected on the socket constitute the loop, and continuous firing a period of time predetermined, that can regulate.Incident of sensor sensing, household electrical appliance will get electric a period of time, for example tens seconds; If sensor sensing to event in rapid succession, can make household electrical appliance continuous that the electrician does.

Compare with " the household electrical appliance automation socket of powered battery, sensor management ", its favourable part of the utility model is: its working power is from civil power, saved the trouble that the user changes battery.

Description of drawings

Below in conjunction with accompanying drawing, further specify the utility model.

Fig. 1 is the circuit theory diagrams of the utility model, wherein, switch S+, S-represents the pair of sensors terminals respectively.

Among the figure, 1. monostable flipflop CD4098,2. ac solid relay SSR, 3. socket.

Embodiment

As shown in Figure 1, the utility model comprises: sensor terminals S+, sensor terminals S-, the monostable circuit that can heavily trigger, ac solid relay and drive circuit thereof, ac solid relay output circuit, hand switch K and D.C. regulated power supply.The monostable circuit that wherein, can heavily trigger is made up of a monostable flipflop CD4098 (1) and peripheral cell thereof.Sensor terminals S+ is suitable for connecting open type transducer or high level output type transducer, and S-is suitable for connecting closed type transducer or low level output type transducer.For the impulse type transducer, it still is S-and indifference that its output is parallel to S+, because each pulse itself not only has rising edge but also have trailing edge.Transducer so cooperates with trigger, makes triggering that the generation of incident both met monostable flipflop along character, again because of inserting current power dissipation that transducer brings also seldom.Except the working power difference, circuit shown in Figure 1 is identical with " the household electrical appliance automation socket of powered battery, sensor management ", and the latter adopts battery-powered.
