Description

A kind of domestic security alarm

Technical field

This utility model relates to a kind of alarm, specifically a kind of domestic security alarm.

Background technology

Alarm is a kind of by preventing or preventing certain event that the consequence caused occurs, and reminds or warn us should take certain electronic product taken action with forms such as sound, light, air pressure.

The network that alarm in the market uses is mostly based on PSTN, GSM or PSTN+GSM, the product having minority uses WIFI network, for PSTN or GSM, when reporting to the police, send warning message or call all can product network communication cost, and though single WIFI network sends warning message and does not produce expense or few expense, but facing power-off, disconnected WIFI with regard to out-of-work potential safety hazard, this utility model domestic security based on WIFI+GSM alarm is contemplated to solve what these problems were arisen at the historic moment.

Utility model content

The purpose of this utility model is to provide a kind of domestic security alarm, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, the following technical scheme of this utility model offer:

A kind of domestic security alarm, including single-chip microcomputer, WIFI module, gsm module, keypad, 433M receiver module, 433M transmitter module, display screen, external equipment output module and external equipment input module, described single-chip microcomputer connects WIFI module, gsm module, keypad, 433M receiver module, 433M transmitter module, display screen, external equipment output module and external equipment input module respectively.

As further program of the utility model: described single-chip microcomputer uses STM32F103.

As this utility model further scheme: use the mode of electric main and internal battery to carry out dual power supply.

Compared with prior art, the beneficial effects of the utility model are: this utility model can be networked by WIFI having electric main when, then are networked by GPRS mode after power-off, and reliability is high.

Accompanying drawing explanation

Fig. 1 is the schematic block circuit diagram of domestic security alarm.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.

Refer to Fig. 1, in this utility model embodiment, a kind of domestic security alarm, including single-chip microcomputer, WIFI module, gsm module, keypad, 433M receiver module, 433M transmitter module, display screen, external equipment output module and external equipment input module, described single-chip microcomputer connects WIFI module, gsm module, keypad, 433M receiver module, 433M transmitter module, display screen, external equipment output module and external equipment input module respectively；Described single-chip microcomputer uses STM32F103；The mode using electric main and internal battery carries out dual power supply.

Operation principle of the present utility model is: refer to Fig. 1, when when being powered by external power source of alarm, alarm networks automatically by domestic WIFI wireless network, constantly external equipment input module (detector such as door magnetic, infrared, cigarette sense, gas sense) duty is pushed to user mobile phone APP, user can control the mode of operation of alarm by APP simultaneously, and alarm and user can also carry out telephone relation；When having a power failure or other powering-off states, alarm is automatically switched to GPRS networking by internal battery powers, alarm by the wireless networking of WIFI, it is achieved normal monitoring and the protection to family.

The interaction of WIFI and GSM:

When plugging in, in the case of having electricity, this utility model connects WIFI, is now to use the work of WIFI wireless network.If the power supply failed for user's family, network breaks, and automatically switches to GPRS network, and the alarm moment this ensures that thering us is in running order.The most here, alarm in the market seldom can accomplish there is GPRS network, is all WIFI network for sharpest edges of the present utility model or technology point, if had a power failure, then uses and can be greatly affected.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.

In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.

Claims

1. a domestic security alarm, including single-chip microcomputer, WIFI module, gsm module, keypad, 433M receiver module, 433M transmitter module, display screen, external equipment output module and external equipment input module, it is characterized in that, described single-chip microcomputer connects WIFI module, gsm module, keypad, 433M receiver module, 433M transmitter module, display screen, external equipment output module and external equipment input module respectively.
