Abstract
The invention discloses a reed power-on switchover time-delay shutdown circuit. The reed power-on switchover time-delay shutdown circuit comprises a two-way reed switch and a reed monitoring circuit, wherein two groups of parallel time-delay shutdown circuits are connected between the output end of the reed switch and the input end of the reed monitoring circuit, and the two groups of parallel time-delay shutdown circuits are mutually connected to form a discharging loop; the output end of the reed monitoring circuit is connected with a power supply, and the output end of the power supply is connected to the reed switch. When the reed switch is subjected to external magnetic switchover, the reed monitoring circuit is automatically power-on and delayed for a few of seconds, carries out corresponding actions on the switching changes of the reed switch in the few of seconds, and then automatically cuts off the power supply of the reed monitoring circuit, and the whole machine has no power consumption in a standby state, thus saving lots of electric energy and meeting the energy conservation and environmental protection policy.
Description
Technical field
The present invention relates to a kind of tongue tube and switch delayed breaking circuit, belong to energy-conserving and environment-protective circuit engineering field.
Background technology
Tongue tube element is widely used in state sensor as a kind of cheap magnetic trigger element.At present, dry-reed tube switch is not in the situation that outside magnetic environment changes, its state is always in folding or off state, if judge, whether dry-reed tube switch is because magnetic environment variation trigger switch is in folding or off state, must guarantee that circuit remains monitor state, therefore the power supply that circuit need to continue, and the kwh loss that continued power causes is appreciable, at some, power supply capacity is required to comparatively strict use occasion, cannot guarantee the work of its long-term stability.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of tongue tube and switch delayed breaking circuit, finish the power supply of rear timely cut-out tongue tube supervisory circuit to realize dry-reed tube switch condition monitoring, with saves energy.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of tongue tube switches delayed breaking circuit, comprise two dry-reed tube switch and tongue tube supervisory circuits of opening, between the input of the output of described dry-reed tube switch and tongue tube supervisory circuit, be connected with two groups of time delayed turn-off circuits in parallel, the described time delayed turn-off circuit of two groups of parallel connections is interconnected to form discharge loop; The output of described tongue tube supervisory circuit is connected with power supply, and the output of described power supply is connected to described dry-reed tube switch.
Wherein, in the time that described dry-reed tube switch senses external magnetic environmental change and wherein described in one group, time delayed turn-off circuit is communicated with, described dry-reed tube switch and time delayed turn-off circuit described in this, tongue tube supervisory circuit and power supply form closed-loop path, time delayed turn-off circuit charging described in this, described tongue tube supervisory circuit continued power, until charging capacitor of time delayed turn-off circuit is saturated described in this, cut off the power supply of described tongue tube supervisory circuit.
Wherein, another charging capacitor repid discharge simultaneously of organizing non-powered described time delayed turn-off circuit is to described tongue tube supervisory circuit.
Pass through technique scheme, tongue tube provided by the invention switches delayed breaking circuit, it can be in the time that dry-reed tube switch be switched by external magnetic, power on and the time delay several seconds automatically to tongue tube supervisory circuit, within this several seconds times, tongue tube supervisory circuit is made after corresponding action the switch change of dry-reed tube switch, this circuit can cut off the power supply of tongue tube supervisory circuit automatically, complete machine does not have power consumption under holding state, only have in the time that dry-reed tube switch is subject to outside magnetic force generation state variation diverter switch again, whole circuit powers on again, complete after corresponding action, again turn-off whole electric power, thereby a large amount of electric energy are saved, meet energy-conserving and environment-protective policy.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described.
Fig. 1 is the structured flowchart that the disclosed tongue tube of embodiment switches delayed breaking circuit;
Fig. 2 is the circuit diagram that the disclosed tongue tube of embodiment switches delayed breaking circuit.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
With reference to figure 1 and in conjunction with circuit diagram shown in Fig. 2, tongue tube provided by the invention switches delayed breaking circuit, comprise two dry-reed tube switch SW1 and tongue tube supervisory circuits of opening, between the input of the output of dry-reed tube switch SW1 and tongue tube supervisory circuit, be connected with two groups of time delayed turn-off circuits in parallel, the time delayed turn-off circuit of two groups of parallel connections is interconnected to form discharge loop; The output of tongue tube supervisory circuit is connected with power supply, and the output of power supply is connected to dry-reed tube switch SW1.
Wherein, in the time that dry-reed tube switch SW1 senses external magnetic environmental change and wherein one group of time delayed turn-off circuit is communicated with, dry-reed tube switch SW1 and this time delayed turn-off circuit, tongue tube supervisory circuit and power supply form closed-loop path, this time delayed turn-off circuit charging, tongue tube supervisory circuit continued power, until the charging capacitor C3 of this time delayed turn-off circuit is saturated, cut off the power supply of tongue tube supervisory circuit.
Wherein, another charging capacitor C7 repid discharge simultaneously of organizing non-powered time delayed turn-off circuit is to tongue tube supervisory circuit.
In conjunction with circuit diagram shown in Fig. 2, operation principle of the present invention is:
In the time that dry-reed tube switch SW1 senses external magnetic environmental change, the time delayed turn-off circuit charging on power supply one tunnel being communicated with it will be triggered;
In the time that the time delayed turn-off circuit on power supply one tunnel charges, tongue tube supervisory circuit continued power, tongue tube control circuit is carried out control action according to the state of dry-reed tube switch SW1, until the charging capacitor C3 of time delayed turn-off circuit on power supply one tunnel saturated after, the power supply of automatically closing tongue tube supervisory circuit, system no longer produces energy consumption;
Sense as dry-reed tube switch SW1 external magnetic environmental change time, will trigger the charging capacitor C7 repid discharge of time delayed turn-off circuit on a non-powered road, so as for state next time switch charge ready;
After the time delayed turn-off circuit on power supply one tunnel has charged, will cut off the power supply of tongue tube supervisory circuit with energy savings.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple modification of above-described embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
