Abstract
The invention discloses a wireless smoke alarming system which is characterized by comprising a smoke collecting circuit, a controller, an acousto-optical alarm and a power conversion circuit; the smoke collecting circuit is connected with the controller and provides fire signals for the controller; the controller is connected with the acousto-optical alarm and controls the acousto-optical alarm to emit alarming signals; the power conversion circuit is connected with the smoke collecting circuit, the controller and the acousto-optical alarm and provides a necessary power source for the smoke collecting circuit, the controller and the acousto-optical alarm. The controller is an AVR series single-chip microcomputer, and the controller is of an ATMEGASL type.
Description
Technical field
The present invention relates to field of intelligent control technology, particularly the wireless smog warning system of one.
Background technology
Fire alarm system is generally made up of smoke detector, warning device, control device and servicing unit etc., there is the physical change such as smog, heat of detection of fires burning initial stage generation, the signal detected is become electric signal by fire detector, be sent to warning device, send alerting signal.Fire alarm system is installed and can helps people's Timeliness coverage initial stage condition of a fire, for taking effective fire suppression measures, evacuation personnel, reducing the loss that fire brings, reducing casualties.
Summary of the invention
For the deficiencies in the prior art, inventing a kind of wireless smog warning system, take AVR single chip as control core, has good Steady speed and compared with high positioning precision (steady-state error is little), also has rapidity simultaneously.
The present invention adopts following technical scheme:
A kind of wireless smog warning system, it is characterized in that, it comprises: smoke collection circuit, controller, audible-visual annunciator, power-switching circuit; Described smoke collection circuit is connected with described controller, for controller provides fire signal; Described controller is connected with described audible-visual annunciator, controls audible-visual annunciator and sends alerting signal; Described power-switching circuit is connected with described smoke collection circuit, controller, audible-visual annunciator, for they provide necessary power supply.
Preferably, described controller is AVR series monolithic, and model selects ATMEGASL.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, a kind of wireless smog warning system, it is characterized in that, it comprises: 1, smoke collection circuit, 2, controller, 3, audible-visual annunciator, 4, power-switching circuit; Described smoke collection circuit is connected with described controller, for controller provides fire signal; Described controller is connected with described audible-visual annunciator, controls audible-visual annunciator and sends alerting signal; Described power-switching circuit is connected with described smoke collection circuit, controller, audible-visual annunciator, for they provide necessary power supply.Preferably, described controller is AVR series monolithic, and model selects ATMEGASL.
ATMEGASL single-chip microcomputer have low cost, low-power consumption, independence, 8, support the function such as serial communication, built-in 10 A/D converters and " house dog " timing, be widely used in industrial control field.For convenience of system upgrade, processor unit is designed with online programming interface circuit, when not taking off control chip, can upgrade fast Single Chip Microcomputer (SCM) program, when single-chip microcomputer RESET is low level, can be programmed to Flash and EEPROM by serial spi bus.Serial line interface comprises SCK, MOSI (input) and MISO (output).RESET be low after, should execution program/erase operations before perform programming allow instruction.
Smoke signal Acquisition Circuit is made up of infraluminescence driving circuit and photoelectric detective circuit.Infraluminescence driving circuit infraluminescence driving circuit is taked by the mode of Single-chip Controlling triode emitter-base bandgap grading level, reaches the object controlling infraluminescence pipe break-make.When needs testing environment cigarette value, open infrared transmitting circuit, exported " 1 " by the PAO of single-chip microcomputer, triode Q1 conducting, infrared tube has electric current to flow through " by the value of adjustment power transformation resistance, can improve the transmitter current of infrared transmitting tube.The cigarette value signal that infrared receiver and amplifying circuit infrared tube receive is very weak, has to pass through the thief hatch that operational amplifier makes just can be sent to after secondary amplifies single-chip microcomputer.
Smoke detector adopts 9V powered battery, but in order to reduce detector power consumption, single-chip microcomputer adopts 3V to power, therefore needs to carry out Power convert.
The present invention comprehensively have employed single-chip microcomputer control technology, sensor Detection Techniques.On hardware, the features such as when using according to system variable element is few, select AVR series monolithic as MCU, the micro-processing controls chip using ATMEGASL as smog alarm main frame, meet user's requirement, and structure is simple, energy consumption and cost are all lower.On software, adopt C language to carry out modular insert and be designed to main, make system software have good readability, and take into full account energy-conservation.System all uses and carries powered battery, improves independence and the reliability of system.
Above the wireless smog warning system of one that the embodiment of the present invention provides is described in detail; for one of ordinary skill in the art; according to the thought of the embodiment of the present invention; all will change in specific embodiments and applications; in sum; this description should not be construed as the restriction to invention, and all any changes made according to design philosophy of the present invention are all within protection scope of the present invention.
