Description

A kind of non-door locking device of SCM Based short message alarm prevention

Technical field

The utility model relates to electricity field, in particular to a kind of SCM Based short message alarm prevents dress of not locking a door It sets.

Background technique

At the end of the 20th century to 21 century at the beginning of, the traditional single one physical prevention door lock requirement phase lance with people to life already Shield, many large size manufacturers gradually involve among the research and development of intelligent entrance guard alarm system, according to current development shape Condition, door access control alarm system is broadly divided into following 2 stages at this stage.

(1) product electronization: being connected using sensor with horns alarms such as buzzers, but alerting effects are bad, It is easily found instead by ruffian.

(2) product long-range: it is connected using sensor with wireless communication modules such as GSM, WIFI, improves and alarm successfully Rate, but be all trigger-type alarming, it is not suitable for the scene for forgetting to close the door.

From the point of view of the door control alarming device studied at present, most of gate inhibition's alarm is all trigger-type alarming, and more For short message, WIFI, bluetooth, buzzer warning smart home anti-theft monitoring system, have no for shutdown problem is forgotten, collection prevention is not The gate inhibition's alarm locked a door with anti-thefting monitoring.

Utility model content

The main purpose of the utility model is to provide a kind of SCM Based short message alarms to prevent non-door locking device, can Effectively to solve the problems in background technique.

To achieve the above object, the technical solution that the utility model is taken are as follows: a kind of SCM Based short message alarm is pre- Prevent non-door locking device, which is characterized in that turn TTL connector including USB, the USB turns TTL connector and is separately connected 5V by Du Pont's line Power supply and SIM800A development board, and SIM800A development board one end connection USB turns TTL connector, SIM800A development board is another 52 single-chip minimum system development boards of end connection, also connect a door sensor in the side of the 52 single-chip minimum system development board Sensor.

Preferably, the USB turns to open up respectively on TTL connector there are two interface, and one is GND interface, another is 5V Power interface.

Preferably, offered respectively on the 52 single-chip minimum system development board USB joint, P30 connector, P31 connector, P20 connector and GND connector.

Preferably, the door status sensor is electrical by P20 connector, GND connector and 52 single-chip minimum system development boards Connection.

Preferably, GND connector, VCC connector, RXD connector and TXD connector are offered on the SIM800A development board, and RXD connector and TXD connector respectively correspond P30 connector and P31 connector on the 52 single-chip minimum system development board.

Preferably, the 5V power supply is connected on 52 single-chip minimum system development boards by USB joint.

Compared with prior art, the utility model has the following beneficial effects:

1, in the utility model, when closing scene switching key by keyboard input module, device, which is in, forgets shutdown mode, Old solitary people can be prevented to be in go out and forget to cause trouble and property loss after closing the door, while being closed prevented also from slight obsessive-compulsive disorder Behind the door it is equal downstairs always suspect oneself whether to have shut door again and can run upstairs check, cause inconvenience to life.

It 2,, can at device and anti-theft modes when passing through keyboard input module Open Scene switch key in the utility model It prevents from stranger from swarming into have no to discover in family, while being opened prevented also from office's air-conditioning, disengaging personnel forget smoothly to close the door.

3. in the utility model, the device and prevention do not lock a door, anti-thefting monitoring；And all gate inhibition's reports on the market The function of alert device optimized at prevention aspect of not locking a door in one, is changed by adjusting the interval time of detection door closure Mode；Solve the problems, such as that old man often forgets to close the door this in family, SMS alarm is more efficient than buzzer warning, may be implemented Long-distance alarm.
