The utility model provides a technical scheme: a household fire alarm comprises an MQ-2 smoke sensor, an MQ-4 natural gas sensor, a flame sensor, an STC12C5A60S2 series single-chip microcomputer, an ESP8266 wireless transmission device, a router, a cloud server, a mobile communication device (mobile phone) and an alarm.

The connecting method of the flame sensor is that an AO port is connected with a P1.1 pin of a singlechip, more accurate numerical values are obtained through internal AD conversion, a DO port is suspended, a VCC port is connected with a 1.5V power supply, and GND is grounded. Then the flame is placed in a kitchen, and when the flame reaches a certain height, the data measured by the single chip microcomputer is fed back.

The MQ-2 smoke sensor adopts the mode that the analog voltage value of an AO port of the MQ-2 sensor is read to judge the indoor smoke concentration, the connection of the analog voltage value makes the AO port connected with a P1.0 port and a DO port of a singlechip suspended, a VCC port connected with a 5V power supply, and GND is grounded. Then the smoke sensor is placed in places such as a living room, a bedroom and the like to sense smoke. The fire information is monitored through the ratio of indoor smoke.

The detection principle of the MQ-4 natural gas sensor is the same as that of the MQ-2 smoke sensor in a wiring mode, and the only difference is that the AO port of the MQ-4 natural gas sensor is connected with the P1.1 pin of a single chip microcomputer. Then the device is placed in a bathroom and a place where a kitchen is easy to generate CO, and when the CO concentration reaches a certain value, monitoring data is obtained and fed back.

The single chip microcomputer is an STC12C5A60S2 series single chip microcomputer as shown in figure 5, one end of an interface on the single chip microcomputer is connected with the sensor in the mode, then a P1.7 pin of the single chip microcomputer is connected with an eighth L ED lamp of the light alarm, when the single chip microcomputer judges that an alarm condition occurs, the pin level is pulled down, the L ED lamp is lightened, and meanwhile, a J3 jumper cap on a development board needs to be connected.

The sound alarm is an external buzzer, the buzzer is connected to a collector of the triode, a base at the other end of the triode is connected with a resistor and then is connected with a pin of the single chip microcomputer, and the resistor is used for protecting a circuit and preventing overload damage. When the development board is used and the buzzer is arranged, the jumper wire cap J4 needs to be connected like an optical alarm, otherwise, the circuit cannot be conducted, and the alarm effect cannot be achieved.

The wireless transmission adopts an ESP8266 wireless transmission module which is connected with a single chip microcomputer and aims to transmit a fire signal to a mobile phone of a user through a cloud end, so that people who are not at home can receive information of firing at home at the first time. The specific connection mode of the device and the singlechip is as follows: an ESP8266 wireless transmission VCC pin is connected with a 3.3V power supply, a GND pin is grounded, a URXD interface is connected with a TXD pin on the singlechip, a UTXD interface is connected with a RXD pin on the singlechip, a RST interface is connected with an IO port/suspension of the singlechip, and a CH _ PD interface is connected with the IO port/VCC on the singlechip.

Then, correspondingly, through sending (AT + CWMODE ═ 2), the AP mode is started, and the lan communication test is used.

Correspondingly, the WIFI module is restarted through sending the (AT + RST), and the system is prevented from making mistakes.

Correspondingly, the hotspot name, the password and the encryption mode are set through sending (AT + CWSAP ═ ESP8266\ and \ "888888 \ and 11, 4).

Accordingly, by sending (AT + CIPMUX ═ 1), multiple devices are allowed to connect to the hotspot.

Correspondingly, through sending (AT + CIPSERVER ═ 1,8080), a port number is set, so that the connection can be conveniently identified by the mobile phone.

Accordingly, the connection never times out by sending (AT + CIPSTO ═ 0).

After each instruction is sent, an OK is returned and displayed by the serial port debugging assistant, and the setting is successful. The three instruction modules are still stored after being powered off, and the three instruction modules are set once after being restarted every time, otherwise, the mobile phone cannot be connected and controlled and can receive and send information, so that problems are prevented, and the single chip microcomputer is set to be capable of sequentially sending the six instructions to carry out initial setting on the wireless module when being powered on and started every time.

And then the wireless transmission module can accurately transmit the fire information to a mobile phone of a user through the router and the cloud server and generate vibration and alarm.

When the intelligent fire alarm is used, a flame sensor, a smoke sensor and a natural gas sensor are adopted for multiple induction, a single chip microcomputer is adopted as a controller, an alarm is generated indoors at the first time, and fire information is fed back to a mobile phone of a user through wireless transmission, so that the intelligent fire alarm adapts to the trend that the number of the old people living alone in the current society is increased, and the mobile phone user can be a child or a daughter who has to live with the parent or the daughter due to various reasons; with the accelerated pace of life, the mobile phone user can be a frequent office worker on business and can master the condition of the home; the indoor alarm can give out sound and light alarm to the solitary old people who are not sensitive to the surrounding things at the first time, so that the old people can escape at the first time, and casualties are reduced as much as possible; meanwhile, the fire place can be accurately positioned through the mobile phone information, precious time is won for fire suppression, and the alarm can be reset through the mobile phone when false alarm occurs.
