[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application, obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0031] The embodiments of the present application disclose an automatic fire extinguishing system of an electric bicycle parking shed, which comprises a smoke sensor, a flame sensor, a single-chip microcomputer, an automatic spraying module, a ventilation fan and an audible and visual alarm module. Figure 1
[0032] The smoke sensor, the flame sensor, the automatic spraying module, the ventilation fan and the audible and visual alarm module are all connected with the single-chip microcomputer.
[0033] The smoke sensor is used for detecting a smoke concentration signal.
[0034] The flame sensor is used for detecting a flame signal.
[0035] The single-chip microcomputer is used for comparing the smoke concentration signal and the flame signal with preset smoke alarm threshold and flame alarm threshold respectively, and controlling the automatic spraying module, the ventilation fan and the sound and light alarm module to act.
[0036] In the embodiment, the smoke sensor adopts an MQ-2 smoke sensor, which is based on the gas-sensitive characteristics of tin dioxide (SnO2) semiconductor. When the sensor is in an environment with combustible gas or smoke, the conductivity of the sensor will increase with the increase of the concentration of the combustible gas (including smoke, etc.), as shown in Figure 3 , the circuit diagram of the MQ2 smoke sensor. When in contact with smoke, if the potential barrier at the grain boundary changes due to smoke, it will cause a change in surface conductivity. The greater the smoke concentration, the greater the conductivity, the lower the output resistance, and the greater the output analog signal. The analog voltage can be converted into a digital signal for further processing and analysis.
[0037] In order to further implement the above technical scheme, the sound and light alarm module includes a buzzer and an alarm lamp.
[0038] In the embodiment, the buzzer is an active buzzer, which has an internal oscillating signal source. After the power is turned on, the internal oscillation system generates an audio signal current. Through the interaction of the electromagnetic coil and the magnet, the diaphragm vibrates periodically, thereby emitting sound. The active buzzer integrates an audio oscillation circuit inside. When connected to the appropriate voltage, it can continuously emit sound, as shown in Figure 4 .
[0039] In order to further implement the above technical scheme, the specific content of controlling the automatic spraying module, the ventilation fan and the sound and light alarm module to act is:
[0040] When the flame value exceeds the upper limit of the preset flame alarm threshold, the single-chip microcomputer controls the red light of the alarm lamp to be on and the buzzer to sound;
[0041] When the smoke value exceeds the upper limit of the preset smoke alarm threshold, the single-chip microcomputer controls the yellow light of the alarm lamp to be on and the buzzer to sound, and simultaneously controls the ventilation fan to rotate to exhaust smoke;
[0042] When the flame value and the smoke value both exceed the upper limit of the threshold value, the single-chip microcomputer controls the green light of the alarm lamp to be on, and simultaneously controls the automatic spraying module to spray water.
[0043] In order to further implement the above technical scheme, the electric bicycle parking shed automatic fire extinguishing system further includes a fan relay module, and the single-chip microcomputer drives the ventilation fan to rotate through the fan relay module.
[0044] In order to further implement the above technical scheme, the electric bicycle parking shed automatic fire extinguishing system further includes a water pump relay module, and the single-chip microcomputer controls the automatic spraying module to spray water by controlling the water pump relay module.
[0045] To further implement the above technical solution, an automatic fire extinguishing system for electric bicycle parking sheds also includes a button module connected to a microcontroller, through which smoke alarm thresholds and flame alarm thresholds are preset.
[0046] To further implement the above technical solution, an automatic fire extinguishing system for electric bicycle parking sheds also includes an LCD display module for real-time display of smoke levels, flame levels, and alarm thresholds.
[0047] In this embodiment, the liquid crystal display module is an LCD1602 liquid crystal display module, such as... Figure 5 The operation of the LCD1602 liquid crystal display module can be divided into two stages: write mode and display mode. In write mode, the microcontroller sends the ASCII codes of the letters, numbers or symbols to be displayed to the LCD1602 liquid crystal display module and transmits these data to the driver through pins. In display mode, by applying voltage to the liquid crystal screen, an electric field can be established on the liquid crystal screen, thereby changing the arrangement state of the liquid crystal molecules and thus realizing the display of pixels.
[0048] To further implement the above technical solution, an automatic fire extinguishing system for electric bicycle parking sheds also includes an analog-to-digital converter chip. The analog-to-digital converter chip is connected to a smoke sensor, a flame sensor, and a microcontroller, respectively, and is used to convert the analog signals of smoke concentration signal and flame signal into digital signals and transmit them to the microcontroller.
[0049] In this embodiment, the analog-to-digital converter chip used is the ADC0832 analog-to-digital converter chip.
[0050] In practical applications, fire-resistant partitions can be implemented in electric bicycle parking areas as needed to prevent fires from spreading and to maximize the protection of people's property and personal safety.
[0051] like Figure 6 The working principle of this utility model's automatic fire extinguishing system for electric bicycle parking sheds is as follows:
[0052] Smoke and flame sensors detect smoke concentration and flame signals in the electric vehicle parking area in real time.
[0053] The analog signals detected by each sensor are converted into digital signals by an analog-to-digital converter chip and sent to the microcontroller for processing;
[0054] The LCD screen displays smoke and flame values, as well as preset flame alarm thresholds and smoke alarm thresholds in real time.
[0055] When the flame value exceeds the preset flame alarm threshold, the microcontroller controls the red light of the alarm light to turn on and the buzzer to sound.
[0056] When the smoke value exceeds the preset upper limit of the smoke alarm threshold, the single-chip microcomputer controls the yellow light of the alarm lamp to be bright, the buzzer to sound, and simultaneously controls the ventilation fan to rotate to exhaust smoke.
[0057] When the flame value and the smoke value both exceed the upper limit of the threshold, the single-chip microcomputer controls the green light of the alarm lamp to be bright, and simultaneously controls the automatic sprinkler module to spray water.
[0058] In order to further implement the above technical solutions, when the smoke value exceeds the preset upper limit of the smoke alarm threshold, the single-chip microcomputer controls the fan relay to be attracted to drive the ventilation fan to rotate to exhaust smoke; when the flame value and the smoke value both exceed the upper limit of the threshold, the single-chip microcomputer controls the water pump relay to be attracted to control the automatic sprinkler module to spray water.
[0059] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts of each embodiment can be referred to each other.

Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
