Abstract
The invention relates to a gas cooker monitoring and warning system and a realization method. The gas cooker monitoring and warning system comprises a micro computer control unit (MCU), a light emitting diode, a voice chip, a power amplification circuit, a loudspeaker, a gas cooker ignition switch, a liquefied gas coal gas sensor module and a power supply. The gas cooker monitoring and warning system and the realization method have the positive effects that the warning prompt can be realized in time under the condition that people close a gas cooker but not completely close the gas cooker, and the personnel injury and the energy source waste caused by fuel gas leakage are avoided.
Description
Technical field
The present invention relates to the monitoring alarm field, particularly a kind of method that the gas combustion range ignition knob situation of closing is monitored.
Background technology
At present; Gas-cooker has got into thousands upon thousands families, brings great convenience for people's life, but almost each family all has and forgotten experience that the gas combustion range ignition knob is closed; Especially old man; This situation maybe be more, in case this thing happens, bring great danger can for the life safety of family.If invent a kind of alarm, when closing gas-cooker but it is not closed and can in time report to the police in dead, close and do not expend power supply again dead the time, can fundamentally avoid above-mentioned danger.
Summary of the invention
The object of the present invention is to provide warning system and the alarm method that to realize above-mentioned purpose.
To achieve these goals, adopt following technical scheme:
The present invention includes microcomputer controller MCU, light emitting diode, speech chip, power amplifier, loudspeaker, gas combustion range ignition switch, liquefied gas and coal gas sensor assembly and power supply.The contact K that the Vcc of microcomputer controller, speech chip, power amplifier and loudspeaker and liquefied gas and coal gas sensor assembly all pass through the gas combustion range ignition switch is connected power supply; The a certain position of the IO mouth of MCU connects the light emitting diode of a band current-limiting resistance; The another one of this IO mouth connects a speech chip; Again with a TTL output that connects the liquefied gas and coal gas sensor assembly, speech chip is connected with power amplifier in this IO mouth, and the output of power amplifier links to each other with loudspeaker.
Gas combustion range ignition switch this supervisory system when closing is broken off with power supply.When the gas combustion range ignition switch opens, switch contact K is closed, so the supervisory system energized begins to keep watch on the state in kitchen, if gas sensor does not detect gas leakage, does not then report to the police; If detected leakage; In order to prevent false alarm; System carries out the delay procedure time-delay a little while, if still detected gas leakage after time-delay a period of time, then lets LED flash; And let speech chip play through the relief loudspeaker of power amplifier to write the voice messaging in the chip in advance, the gas-cooker that can in time point out the household not close like this closes; If do not detect gas leakage after time-delay a period of time, then do not report to the police, continue to keep watch on the state in kitchen; If the gas combustion range ignition switch thoroughly cuts out, supervisory system was disconnected with being connected of power supply, thereby can saves energy.
Description of drawings
Fig. 1 is the theory diagram of one embodiment of the invention.
Fig. 2 is the process flow diagram that the present invention representes how to realize monitoring in real time and economize on electricity.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof technology contents of the present invention is done further to specify.
As shown in Figure 1, a kind of gas-cooker monitoring and alarming system and implementation method comprise microcomputer controller MCU1, power supply 2, light emitting diode 3, loudspeaker 4, power amplifier 5, speech chip 6, liquefied gas and coal gas sensor assembly 7, gas combustion range ignition K switch.It is characterized in that: MCU1, light emitting diode 3, loudspeaker 4, power amplifier 5 and speech chip 6 all pass through ignition switch K and link to each other with power supply 2; The a certain position (such as P1.0) of the IO mouth of MCU connects the light emitting diode 6 of a band current-limiting resistance; The another one (such as P1.1) of the IO mouth of MCU connects speech chip 6; Speech chip 6 links to each other with power amplifier 5, and the output terminal of power amplifier links to each other with loudspeaker 4.The a certain position (such as P1.2) of the IO mouth of MCU connects the TTL output terminal of liquefied gas and coal gas sensor assembly 7.
The course of work of supervisory system of the present invention is:
As shown in Figure 2, if the ignition switch of gas-cooker is closed extremely, the electric switch of gas-cooker will break off, so the power supply of supervisory system and gas-cooker breaks off.If because the ignition switch of human negligence gas-cooker is not closed, the electric switch of gas-cooker is closed, so just make supervisory system connect power supply; But system can not report to the police immediately, but will let gas sensor detect whether gas leakage is arranged, if detected leakage; Also to delay time a period of time; Time-delay detects whether leakage is arranged later again, if do not detect leakage, explanation is a fire just commonly used; If detected leakage again after the time-delay, just start sound and light alarm immediately.
Good effect of the present invention is can be when people close gas-cooker but do not have to close under the good situation alarm in time, avoid owing to gas leakage causes personal injury and energy dissipation.
Must be pointed out that above-mentioned instance is just made an indefiniteness to the present invention and illustrated.But person of skill in the art will appreciate that, do not departing under aim of the present invention and the scope that can make various modifications, replacement and change to the present invention, these modifications, replacement and change still belong to protection scope of the present invention.
Claims (2)
