Description

A flue fire prevention and extinguishing device intelligently controlled by a mobile phone

technical field

The utility model relates to a flue fire prevention device, in particular to a flue fire prevention device intelligently controlled by a mobile phone.

Background technique

Most of the current kitchen fire detection systems use traditional fire detection devices, such as smoke, temperature, gas, photosensitive and composite detectors, which are mainly installed on the kitchen ceiling and walls. Due to the special properties of the flue grease, such as rapid temperature rise, high ignition temperature, and relatively closed flue, if the current fire detection device is directly installed on the flue, it will easily reduce the sensitivity and shorten the service life. As long as there is a fire in the flue, this fire detector can only detect the fire after the fire in the flue has spread to other spaces in the kitchen. This has delayed the best time to extinguish the fire, making it difficult to ensure fire safety in the kitchen. Usually, a water tank is used for pressure supply in the kitchen flue, so that a water network can be formed at the inlet of the flue, thereby reducing the temperature of the flue gas, extinguishing sparks, and eliminating fire hazards. However, it is worth noting that it may be difficult to control the temperature in the flue in the past with the flue fire prevention system. The return water contains oil and other debris, which can easily block the water outlet arranged in the flue, causing the system to be paralyzed and unable to work normally. And need to be in working condition all the time, this has just caused the waste of water resource. Many are now smart systems and remote control has become common.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, the utility model comprises micro-controller, and micro-controller is respectively connected with detection module, threshold adjustment module, fire extinguishing module, alarm module, power supply module, and is used for carrying out wireless communication with mobile phone, sends alarm information to mobile phone and receives mobile phone The communication module of the control command issued is connected; the fire extinguishing module includes a sewage system, a flue valve, a fan system and a sprinkler system all connected with a microcontroller. The microcontroller is also connected with an LCD display module for displaying temperature status. The power supply module includes a 5V regulated power supply connected to the microcontroller through a switch, and an indicator lamp connected to the microcontroller to indicate the working state. The working state of the device is controlled by a switch.

The alarm module adopts BRJ-103 sound and light alarm. The microcontroller adopts STC89C51 single-chip microcomputer. The detection module adopts E-type thermocouple temperature sensor. The LCD display module adopts LCD1602 liquid crystal display. The communication module adopts the GSM TC35I communication module produced by Siemens.

Referring to Fig. 2, the concrete use of the present utility model is as follows:

The device is used for fire prevention and extinguishing of the flue, and has the functions of flue cleaning and mobile phone control. The temperature sensor can be used to measure the actual temperature in the oil flue, and then the signal is amplified by the signal conditioning and sent to the threshold comparison module to compare it with the previously set threshold temperature, and the output result is 6 switch control signals. The first way is to control the sound and light alarm module to give real-time alarm, which can let the staff in the relevant operation room and operation desk know that there is a fire at the first time and take timely measures; the second way is to turn on the sprinkler system to extinguish the fire. The temperature in the flue is relatively high. At this time, spraying water will generate steam, which can quickly reduce the oxygen concentration at the ignition point. On the other hand, lowering the temperature can ensure the fire extinguishing effect; the third way is to turn off the switch of the fan system to stop the air convection, which is effective Prevent the flame from entering the fan, so as to avoid huge losses; the fourth switch is to close the flue valve at the same time as the other switches are turned on, using the suffocation principle to prevent the flame from escaping and enhance the fire extinguishing effect; the fifth is the sewage system, which will cycle It can be opened and closed automatically, and the oil and sewage produced by fire extinguishing can be discharged from the sewer; the sixth channel is the GSM/CDMA communication module, which will send the alarm signal to the mobile phone, and can also transmit the user's command to the single-chip microcomputer through the GSM/CDMA module. Then adjust the device accordingly to realize remote mobile phone control.

Referring to Figure 3, it is a flow chart of communication between the GSM module and the microcontroller through the AT command. The command symbols, constants, PDU data packets, etc. of all AT commands are transmitted in ASCII coded form. If it is determined to use the single-chip microcomputer to send a short message to the GSM module, first send AT to establish a connection between the single-chip microcomputer and the GSM module. If the connection is successful, it will return Acknowledge frame "OK". There are two ways to send and receive SMS information, text mode and PDU (protocol description unit) mode, generally PDU mode is common to any mobile phone. After the connection is successful, send AT+CMGF=0 to indicate the PDU mode is selected, and if ">" is received, it indicates that the module numbers of the calling parties have been obtained successfully and data can be transmitted. This makes it possible to send commands according to the user's own needs. When the mobile phone receives a complete AT command, the mobile phone does not execute this command immediately, but first sends all the ASCII code sequences of the AT command just received (including 0DH), and then sends a carriage return and the ASCII encoding of the line break, namely 0DH and 0AH, and finally execute this instruction.
