Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is made detailed description further.

Referring to Fig. 1; The utility model comprises microcontroller, and said microcontroller connects water pumper module, sensitization detecting module, roller shutter module, Keysheet module, supplementary lighting module, humiture detection module, gsm module, voice module, remote controller module, flame detection circuit and display module.

Referring to Fig. 2, said microcontroller is Chip Microcomputer A t89s52, can realize controlling water pumper, the roller shutter motor, and 12864 liquid crystal displays, humiture is monitored in real time, functions such as antitheft, fire prevention.Resource is very abundant on the sheet of single-chip microcomputer, and 32 I/O mouths are arranged, and on port assignment, the utility model uses P0, P1, P2, P3.The P1 port is a keyboard detection, and the P2 port is used for the detection of sensor and the demonstration of liquid crystal, and the P0 port is used to control peripheral circuit, and the P3 port is used for communicating with gsm module.

Referring to Fig. 3, pumping motor and roller shutter motor are all driven by motor-driven L298N module, are linked to each other with L298N by four IO mouths, export four road signals and control two motors.

Referring to Fig. 4, said humiture detection module adopts Temperature Humidity Sensor DHT21.Temperature Humidity Sensor is installed in the inboard left position of booth, detects the humiture in the booth through the humiture module, can pass to single-chip microcomputer to real-time humiture; Work as temperature, or humidity is when surpassing limit value, single-chip microcomputer can be controlled gsm module and play alarm call to householder's mobile phone; Also can send short breath (user can set up on their own), notify current information, wherein temperature limit definite value and humidity limit value in user's booth; With householder's phone number, can set up on their own.Content that alarm call is reported is controlled by voice module, and system can carry out air draft operation voluntarily, to reduce temperature or humidity.

Referring to Fig. 5, be installed in the inboard left position of booth, when indoor certain some detected parameters surpassed setting value, single-chip microcomputer can be controlled gsm module, to householder's mobile phone dialing phone or transmission note (user can set up on their own).

Referring to Fig. 6, as display module, be installed in the inboard anterior position of booth with 12864 liquid crystal, display module can show real time temperature and the humidity situation in current service time and the current booth, and is furnished with multilevel menu, explicit user the information that will know.
