Abstract
The invention discloses a circuit apparatus capable of controlling starting and stopping of a one-chip microcomputer by an inductive switch. The circuit apparatus at least includes one inductive switch and one one-chip microcomputer and is characterized in that the inductive switch is in series connection between the one one-chip microcomputer and a power source. One advantage of the apparatus is that an induction signal or a sensing signal is used as a starting and stopping switch of the one-chip microcomputer. According to the apparatus, the sensing signal is simultaneously used as a starting and stopping command of the one-chip microcomputer, so that a power-consuming standby working mode in which the one-chip microcomputer circuit is in a long-term power-on state to wait for arrival of a signal is changed into a working mode in which the one-chip microcomputer is not electrified until the sensing signal arrives and is disconnected immediately after the operation. Therefore, not only can power be substantially saved, but also the disconnection of the one-chip microcomputer enables interferences of magnetoelectricity, static electricity and a lightning stroke and the like to be avoided. The apparatus enables the circuit to be in a waiting state with zero power consumption on a controlling occasion on which anti-theft alarming, fire alarming, and standby detection and the like are in a waiting state most of the time; and a minicell can be used to supply power for replacing original commercial power supply. Moreover, energy and power are saved and cost is reduced; and product reliability and service life are substantially improved.
Description
Technical field
The invention belongs to circuit control device, definite saying is the intelligence controlling device of a kind of inductive switch control single chip computer start and stop.
Background technology
More the circuit that is used for intelligence controlling device at present adopts single-chip microcomputer to gather induced signal or accepts the mode of external order.These modes all are to let single-chip microcomputer be in the state that energising is waited for, gather pulse or the switching signal that comes from transducer or checkout gear then.No matter signal comes soon, slowly or do not come the start of all will switching on of signal, single-chip microcomputer to wait there.Like this, just a lot of problems have been brought.At first be exactly the problem of external disturbances, in the time of single-chip microcomputer booting wait, meet interference signals such as static, electromagnetism, thunderbolt, control will produce mistake, or directly causes single chip microcomputer halt; Next is the problem of power consumption, although the single-chip microcomputer power consumption is few, for powered battery, wireless transmission, the inconvenient occasion of civil power, also is very considerable; In addition, owing to the irregular variation and the single-chip microcomputer of extraneous signal is difficult to reasons such as identification, cause the situation of error of performance also to happen occasionally; Also have because the complete machine failure rate that long-term energising start brings and useful life problem etc.
In order to overcome the above problems, single-chip microcomputer has adopted the working method of standby dormancy under many situation, but this mode is "on" position after all, and need often wake work up, and single-chip microcomputer still is difficult to resist external various interference; The identification pulse signal still be interference signal be difficult problem always, in the practical application error of performance with cause the situation of fault to happen occasionally.Test and experience all prove, want to overcome the above problems at all, have with the starting switch of external order (switching signal) as single-chip microcomputer work moment start, the power cutoff that finishes of working only.
Summary of the invention
Energising power consumption that standby brought when not having task, be subject to disturb and problems such as operation troubles, the present invention proposes a kind of moment energising during single-chip microcomputer work that lets, after hours the outage working method and the device of shutting down in order to solve single-chip microcomputer.The circuit arrangement of a kind of inductive switch control single chip computer start and stop promptly is provided
Technical solution of the present invention is achieved in that the circuit arrangement of these inductive switch control single chip computer start and stop, has an inductive switch and a single-chip microcomputer at least, it is characterized in that inductive switch is connected between single-chip microcomputer and the power supply.
Beneficial technical effects of the present invention is: with the start stop switch of induction (or sensing) signal as single-chip microcomputer; With switch on the for a long time working method of the power consumption standby that waiting signal arrives of single chip circuit in the past; Become transducing signal and come just energising; The working method of just cutting off the power supply after the complete operation has not only been saved power supply greatly, and shuts down and avoided interference such as magnetoelectricity, static, thunderbolt.At burglar alarm, fire protection warning, treat that the mosts of the time such as machine testing all are in the control occasion of wait state, this device can make circuit be in the wait state of zero-power, is the original mains-supplied of instead with minicell.Energy-conservation economize on electricity, reduce cost, and improved greatly reliability of products and useful life.
Description of drawings
Embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present invention and use are elaborated.
Embodiment 1: with reference to accompanying drawing 1, the circuit arrangement of these inductive switch control single chip computer start and stop has an inductive switch (1) and a single-chip microcomputer (2), it is characterized in that inductive switch (1) is connected between single-chip microcomputer (2) and the power supply (V).
Embodiment 2: with reference to accompanying drawing 2, the circuit arrangement of these inductive switch control single chip computer start and stop is characterized in that between said inductive switch (1) and single-chip microcomputer (2), also having a relay as auxiliary switch (3).
Embodiment 3: with reference to accompanying drawing 3, the circuit arrangement of these inductive switch control single chip computer start and stop is characterized in that between power supply (V) and single-chip microcomputer (2), being connected with key switch (1), is in parallel with relay (3) as auxiliary switch.When needs work (for example gate inhibition's intercom system); Click switch (1); Connect single-chip microcomputer (2) work, after the work such as the contacting of the relay (2) that single-chip microcomputer (2) will break off originally (this moment maybe key switch (1) break off), single-chip microcomputer (2) handle for example intercommunication, unblank; Again relay (3) contact is broken off, recovered the state that outage is shut down.
Embodiment 4: with reference to accompanying drawing 4; The circuit arrangement of these inductive switch control single chip computer start and stop; It is characterized in that also having in the circuit of the relay as auxiliary switch (3) between inductive switch (1) and single-chip microcomputer (2) one and be communicated with and be connected in simultaneously the recovery switching circuit (4) on the relay (3) as auxiliary switch with power supply (V) and single-chip microcomputer (2); Inductive switch among the figure (1) is a normally closed switch, and the circuit (4) that recovers switch is the circuit that FET and resistance constitute.When magnet steel during near inductive switch (1); Inductive switch breaks off, and because of grid is the low level conducting, power supply is communicated with single-chip microcomputer (2) through the contact 1,3 of FET, relay (3) in the restore circuit; Single-chip microcomputer work; Through after the of short duration processing, forward the contact of relay (3) to 2, the single-chip microcomputer outage is shut down.After this, after magnet steel was removed, inductive switch was closed, and power supply takes back 1 with relay contact through contact 2,3 UNICOM's single-chip microcomputers of relay after the single-chip microcomputer work, restPoses.Go round and begin again with this.
