Description

A kind of low-power consumption photoelectric smoke detector

Technical field

The utility model relates to a kind of photoelectric smoke detector, belongs to the protection alarm device field.

Background technology

At present, photoelectric fire detecting device, photoelectric smoke detector are one of security protection equipment of widespread use, mainly are the abnormal informations such as smokescope, flame, electric light in the testing environment, and give the alarm, for evacuating personnel and the condition of a disaster rescue provide the information indication.Because the circuit that can influence usually in the room causes outage, therefore all can in detector or at its outside standby power supply (normally accumulator) that connects separately, in case of emergency be the detector power supply usually when fire occurring.But existing detector does not adopt the design of any reduction power consumption when design, or only is to reduce power consumption by the processor dormancy strategy merely, causes power consumption higher, has shortened the working time during reserve battery is powered.

Summary of the invention

Still this present situation of photoelectric smoke detector that lacks low-power consumption at present this area, the utility model discloses a kind of photoelectric smoke detector of low-power consumption, improve by the circuit design to integral body, power consumption when reducing product standby and warning, more energy-conserving and environment-protective, working time when prolonging the reserve battery power supply, during the civil power outage fire hazard monitoring time longer, reduced accident rate.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of low-power consumption photoelectric smoke detector, comprise photoelectric sensor, amplifier module, MSP430 single-chip microcomputer, LED indicating module, power module, wherein photoelectric sensor is connected with the amplifier module, the amplifier module is connected to the MSP430 single-chip microcomputer, the MSP430 single-chip microcomputer connects the LED indicating module, and power module connects photoelectric sensor, amplifier module, MSP430 single-chip microcomputer and LED indicating module.

The MSP430 single-chip microcomputer is 16 single-chip microcomputers of a kind of high-performance super low-power consumption, and can enter dormant state when standby, and this single-chip microcomputer has abundant processor control function, is conducive to realize controlling the power consumption of other parts.

In the utility model, the LED indicating module can be multiple different implementation, for example LED light emitting array, LED display etc., and preferably described LED indicating module is the LED lamp, cost is low, and is easy to control, can effectively reduce power consumption.

In the utility model, described amplifier module is DIO2052A, amplifier unit as a kind of super low-power consumption, DIO2052A is the binary channels operational amplifier, and low in energy consumption to 16uA, can make its only power supply when controller is patrolled and examined by MSP430 Single-chip Controlling amplifier DIO2052A power supply, cut off the electricity supply during standby, reduce power consumption to greatest extent.

In the utility model, described MSP430 single-chip microcomputer adopts the power supply of 32.768K external crystal-controlled oscillation, that is to say dormancy when the standby of MSP430 single-chip microcomputer, and power module adopts the 32.768K external crystal-controlled oscillation that the MSP430 single-chip microcomputer is powered, not only for system provides stable clock, reduce power consumption again to greatest extent.

In order further to reduce power consumption, the described LED lamp of described MSP430 Single-chip Controlling is lighted with pwm pulse, owing to adopt the power supply of pulse mode control LED lamp, can make the LED lamp seem not glimmer and can reduce LED power consumption over half again.

Detector of the present utility model, in order to improve its serviceable life, and assurance excellent flame-retardant performance, described photoelectric sensor, amplifier module, MSP430 single-chip microcomputer, LED indicating module, power module is positioned on the same electronic circuit board, electronic circuit board is installed in the ABS shell, is connected with outside by ABS wiring base.

By above-mentioned design, detector of the present utility model has reduced overall power to greatest extent, thereby has guaranteed the service time of product when using the reserve battery power supply, and the fire system monitoring period is longer during the civil power outage, has reduced the fire failure incidence.
