Abstract
The utility model discloses a kind of electric bell control device.Comprise: direct supply (1), single-chip microcomputer (2), triode (3), relay (4), electric bell (5), AC power (6), the first resistance (7), the second resistance (8).During use, single-chip microcomputer (2) is made to produce control signal by programming, this signal amplifies rear drive relay (4) and electric bell (5) work through triode (3), can control the electric bell number of times that at the appointed time snap is fixed.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of electric bell control device.
Background technology
Electric bell utilizes the characteristic of electromagnet, form main magnetic circuit by the closing device repeatedly of the power switch current switching controlling to be wrapped in main magnetic core coil alternately to change with being separated the magnetic circuit adhesive of elastic suspension magnetic core, the electric hammer be connected on elastic suspension magnetic core is produced in bell surface vibrate and send the tinkle of bells, go the length of informing people's work and study time to make a reservation for.Electric bell has AC and DC two kinds.
One chip microcomputer is called for short single-chip microcomputer, is typical embedded microcontroller (Microcontroller Unit), and the abbreviation MCU of conventional English alphabet represents single-chip microcomputer, and it is be used in industrial control field the earliest.Current single-chip microcomputer penetrates into the every field of our life, is almost difficult to find which field not have the trace of single-chip microcomputer.Single-chip microcomputer runs by program, and can revise.Realize different functions by different programs, by program, with single-chip microcomputer can control LED easily, charactron lights speed and the rotating speed of motor, various random digit can be produced easily and to go forward side by side row operation.The high intelligence of product can be realized, high-level efficiency, and high reliability by program.
Relay is a kind of electric control device, is when the change of input quantity (energizing quantity) reaches regulation requirement, makes controlled volume that a kind of electrical equipment of predetermined Spline smoothing occurs in electric output circuit.It has control system (also known as input circuit) and by the interactive relationship between control system (also known as output loop).Usually be applied in the control circuit of robotization, it is actually the one " automatic switch " going to control big current running with small area analysis.Therefore play the effects such as automatic adjustment, safeguard protection, change-over circuit in circuit.Electromagnetic type relay is generally made up of iron core, coil, armature, contact reed etc.As long as add certain voltage at coil two ends, certain electric current will be flow through in coil, thus generation galvanomagnetic effect, the pulling force that armature will overcome return spring under the effect of electromagnetic attracting force is inhaled to iron core, thus the moving contact of band moving armature and stationary contact (normally opened contact) adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return to original position at the reacting force of spring, makes moving contact and original stationary contact (normally closed contact) adhesive.Such adhesive, release, thus the object reaching conducting in circuit, cut-out.For " often open, normally closed " contact of relay, can distinguish like this: the stationary contact being in off-state when relay coil is not energized, be called " normally opened contact "; The stationary contact being in on-state is called " normally closed contact ".
Summary of the invention
In Industry Control, sometimes need to allow electric bell ring different number of times in the different time.The purpose of this utility model is to design that a kind of structure is simple, easy to use, dependable performance, cheap electric bell control device, can control the electric bell number of times that at the appointed time snap is fixed.
For achieving the above object, the utility model comprises: direct supply (1), single-chip microcomputer (2), triode (3), relay (4), electric bell (5), AC power (6), first resistance (7), second resistance (8), it is characterized in that: the positive pole of direct supply (1) connects the positive pin of power supply of single-chip microcomputer (2), the negative pole of direct supply (1) connects the power-pin of single-chip microcomputer (2), an input and output pin of single-chip microcomputer (2) is connected and is connect the base stage of triode (3) after the second resistance (8), one termination direct supply (1) positive pole of relay (4) input circuit, the collector of another termination triode (3) of relay (4) input circuit, the emitter of triode (3) is connected after the first resistance (7) and is connect direct supply (1) negative pole, total n (the 1 < n < 21) of electric bell (5), one end of a relay termination (4) output loop after n electric bell (5) is in parallel, the zero line of another termination AC power (6), the other end of live wire contact relay (4) output loop of AC power (6).
