Description
Technical field
This utility model is related to technical field of fire control, and in particular to be a kind of double bus fire acousto-optic alarm.
Background technology
Existing acoustooptic alarm, all employs four-wire system (including the double bus, 24V power supplys) mode of connection, normally substantially
During work, need to be powered (comprising circuit for alarming, optocoupler, timer circuit and sound chip for circuit for alarming using 24V circuits
Deng), then recycle bus to be combined with each other communication.Shown in Fig. 1, the as structural representation of one of which acoustooptic alarm,
This acoustooptic alarm is mainly by double bus, LDO stabilivolts, single-chip microcomputer, control circuit, light drive circuit, 555 intervalometers, LED
The compositions such as warning light, alarm song drive circuit, sound chip, resonator, 24V power circuits, detection circuit.
Although above-mentioned acoustooptic alarm can meet the normal work of acoustooptic alarm, following deficiency is there is also：
(1) whole circuit components are more, integrated level is low, thus circuit design difficulty is larger, and printed board is relatively costly, and
Whole circuit power consumption is very big (having reached 20~30mA).
(2) during in-site installation, cabling requirement is higher, and wiring difficulty and workload is larger, waste time and energy, and because 24V
The presence of circuit, so when applying at the scene, in addition it is also necessary to dispose the cable of 24V.Due to being typically not less than using diameter at present
1.5mm2Copper core connected up, therefore, another direct result that existing acoustooptic alarm is brought is to be added significantly to
Overall wiring cost.
To sum up, how to simplify the structure design of acoustooptic alarm, reduces cost improves wiring and installation effectiveness, become for
One of technical problem underlying of those skilled in the art's urgent need to resolve.
Utility model content
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of double bus fire acousto-optic alarm, can be big
Width simplifies the structure design of acoustooptic alarm, reduces cost, and improves installation effectiveness.
For achieving the above object, the technical solution adopted in the utility model is as follows：
A kind of double bus fire acousto-optic alarm, including double bus, LDO stabilivolts, single-chip microcomputer, light drive circuit, alarm
Sound-driving circuit, LED warning lights and resonator；Access double bus, other end connection single-chip microcomputer input in described LDO stabilivolts one end
End, the voltage voltage stabilizing for double bus to be exported is converted to single-chip microcomputer running voltage；The light drive circuit and alarm are sound-driving
Circuit accesses double bus, by double bus powered operation；The light drive circuit input is connected with single-chip microcomputer output, output
End is connected with LED warning lights, for controlling LED warning light break-makes；The alarm song drive circuit input is exported with single-chip microcomputer
End connection, outfan is connected with resonator, sounds the alarm for controlling resonator.
Compared with prior art, this utility model has the advantages that：
(1) this utility model is sound-driving by light drive circuit and alarm by the rational modification to existing acoustooptic alarm
Circuit is directly connected on double bus, and using Single-chip Controlling light drive circuit and alarm song drive circuit works.Due to two total
Line has nonpolarity, can be powered for circuit thereafter, thus on the premise of acoustooptic alarm normal work is ensured, this reality
With the new design for having dispensed the part such as 24V power circuits and control circuit, detection circuit, sound chip, so as to simplify
The structure of whole acoustooptic alarm, reduces circuit design difficulty, power consumption and components and parts cost.
(2) this utility model is when in-site installation is carried out, due to without the concern for the wiring of 24V circuits, so on the whole
The species of wiring is decreased, the difficulty of wiring is reduced, and because nonpolarity, the butted line no requirement (NR) of double bus, so
Operational complexity is decreased, the efficiency of installation is effectively increased, cable cost is reduced.Therefore, this utility model institute
The technique effect of acquirement is clearly.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with embodiment for explanation, and mode of the present utility model includes
But it is not limited only to following examples.
As shown in Fig. 2 this utility model provides a kind of double bus fire acousto-optic alarm, it includes that double bus, LDO are steady
Pressure pipe, single-chip microcomputer, light drive circuit, alarm song drive circuit, LED warning lights and resonator.
Access double bus, other end connection single-chip microcomputer input in described LDO stabilivolts one end.The single-chip microcomputer output is same
When be connected with light drive circuit and the respective input of alarm song drive circuit, and light drive circuit and alarm song drive circuit are equal
Access double bus, powered by double bus, Single-chip Controlling work；The LED warning lights are connected with light drive circuit outfan, by
Light drive circuit controls break-make；The resonator is connected with alarm song drive circuit outfan, is controlled by alarm song drive circuit
Sound the alarm.Shown in Fig. 3, partial circuit diagram as of the present utility model.
Single-chip microcomputer, light drive circuit and the alarm song drive circuit that this utility model is adopted is existing mature technology,
Therefore here no longer individually introduces one by one concrete composition.Main innovation point of the present utility model be using double bus be single-chip microcomputer,
Light drive circuit and alarm song drive circuitry, Single-chip Controlling light drive circuit and alarm song drive circuit works, so as to
Cancel the design of the part such as 24V power circuits and control circuit, detection circuit, sound chip, simplify circuit design structure, and then
Design cost and wiring cost are saved, and effectively reduces power consumption, improve wiring and the efficiency installed.This utility model is excellent well
The application performance of acoustooptic alarm is changed, compared with prior art, it has substantial feature and progress.
