Abstract

The invention discloses a power-saving family entrance door monitoring alarm system and an implement method. The power-saving family entrance door monitoring alarm system comprises a micro-computerized controller (MCU), a voice chip, a power amplifier circuit, a horn, a light-emitting diode (LED), a limiting switch with a normally-opened contact and a normally-closed contact, and a power source. The power-saving family entrance door monitoring alarm system has the advantages of achieving timely alarming prompting under the condition that when people close an entrance door but do not close well, avoiding the phenomenon that a thief enters into a house, personal injuries and property loss are caused due to the fact that the entrance door is not well closed, and disconnecting from the power source and therefore saving energy under the condition that the entrance door is closed.

Description

A kind of family's entry door monitoring and alarming system and implementation method of economize on electricity
Technical field
The present invention relates to the monitoring alarm field, particularly a kind of method that family's entry door situation of closing the door is monitored.
Background technology
At present, antitheft door has all been installed with entry door by most families, antitheft door is as the term suggests usurp for anti-, but almost there is the experience that it is not shut in each family when closing entry door, especially old man, this situation may be more, bring great danger for like this life property safety of family.If invent a kind of alarm, close entry door but when it not being shut can and alarm, do not expend again power supply when shutting, can fundamentally avoid above-mentioned danger.And then the work that allows people feel at ease.
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, by the following technical solutions:
The present invention includes microcomputer controller MCU, speech chip, power amplifier, loudspeaker, light emitting diode, band is often opened limit switch and the power supply with normally closed contact.The Vcc of microcomputer controller, speech chip, power amplifier and loudspeaker are connected the normally closed contact that passes through limit switch and are connected power supply, the P1.0 of MCU connects the light emitting diode with current-limiting resistance, P1.1 connects a speech chip, and the external interrupt input end INT0 of MCU is connected to ground by the normally open contact of limit switch.Speech chip is connected with power amplifier, and the output of power amplifier links to each other with loudspeaker.
Entry door normally closed contact of limit switch when closing disconnects.When entry door was opened, the normally closed contact of limit switch was closed, so the supervisory system plugged begins to monitor the state of entry door.When entry door is pent, no matter can be shut, all can be with the normally opened contact closure of limit switch once, so send an external interrupt signal to MCU.If entry door is closed in the dust, then the normally closed contact of limit switch disconnects, and supervisory system and power supply disconnect, and system can not report to the police; If entry door is not shut, because supervisory system is connected with power supply by the normally closed interlock of limit switch, by program design, allow LED flash, and allow speech chip play the voice messaging of writing in advance in the chip by the relief loudspeaker of power amplifier.So in time the entry door that will not shut of indicating closing door people shuts.
Description of drawings
Fig. 1 is the theory diagram of one embodiment of the invention.
Fig. 2 is that the present invention represents how to realize Real Time Monitoring and energy-conservation process flow diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof technology contents of the present invention is described in further detail.
As shown in Figure 1, a kind of family's entry door monitoring and alarming system and implementation method of economize on electricity comprise microcomputer controller MCU1, power supply 2, speech chip 3, power amplifier 4, loudspeaker 5, light emitting diode 6, limit switch normally closed interlock SQ_1, normally open contact SQ_2.It is characterized in that: the normally closed contact that MCU1, speech chip 3, power amplifier 4, loudspeaker 5 all pass through limit switch links to each other with power supply 2, the P1.0 of MCU connects the light emitting diode 6 with current-limiting resistance, the P1.1 of MCU connects a speech chip 3, speech chip 3 links to each other with power amplifier 4, and the output terminal of power amplifier links to each other with loudspeaker 5.The external interrupt input end INT0 of MCU is connected to ground by the normally open contact of limit switch.
The course of work of supervisory system of the present invention is:
As shown in Figure 2, whether the normally closed contact that whether the opening of entry door determined limit switch is closed, closed under the spring action of section within it of the normally closed contact of limit switch if entry door is opened, so just make supervisory system connect power supply.Can entry door in the process of closing (no matter shut) can bump a lower position switch, so can make the normally opened contact closure of limit switch once, can send an external interrupt signal this moment to MCU, if entry door is not shut, this moment since supervisory system also by Power supply, by program design, send sound and light alarm; If entry door has been shut, the normally closed contact of limit switch will be disconnected, so cut off the power supply of supervisory system.
Good effect of the present invention is: 1, can be when people close entry door but in the situation about not shutting timely alarm, thereby avoid not drawn the thief and registering one's residence and cause personal injury and property loss owing to entry door shuts; 2, energy savings, this has benefited from normally closed contact that the present invention adopted limit switch is connected supervisory system with power supply ingehious design.
Must be pointed out that above-mentioned example 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)

1. family's entry door monitoring and alarming system and the implementation method of an economize on electricity is characterized in that this system comprises microcomputer controller MCU, speech chip, and power amplifier, loudspeaker, light emitting diode, band is often opened limit switch and the power supply with normally closed contact; The Vcc of microcomputer controller connects power supply by the normally closed contact of limit switch, the P1.0 of MCU connects the light emitting diode with current-limiting resistance, P1.1 connects a speech chip, and the external interrupt input end INT0 of MCU is connected to ground by the normally open contact of limit switch.Speech chip is connected with power amplifier, and the output of power amplifier links to each other with loudspeaker.
2. family's entry door monitoring and alarming system and the implementation method of a kind of economize on electricity as claimed in claim 1, it is characterized in that the method is, whether the normally closed contact that whether the opening of entry door determined limit switch is closed, if entry door is opened, closed under the spring action of section within it of the normally closed contact of limit switch, so just make supervisory system connect power supply.Entry door can bump a lower position switch in the process of closing, so can make the normally opened contact closure of limit switch once, can send an external interrupt signal this moment to MCU, if entry door is not shut, this moment since supervisory system also by Power supply, so can send sound and light alarm; If entry door has been shut, the normally closed contact of limit switch will be disconnected, so cut off the power supply of supervisory system.
