[0040] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0042] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] The embodiment of the present application provides a wireless transmission wind flow gas monitoring system, such as Figure 1 As shown, the system includes:

[0044] Power supply module, light control wake-up module, single chip microcomputer, gas detection module, pulse power-on control module, wireless transmission module, display module;

[0045] The power supply module is electrically connected to the pulse power-on control module, the light-controlled wake-up module, the wireless transmission module and the display module to provide power.

[0046] The pulse power-on control module is electrically connected to the gas detection module and is used to transmit the power provided by the power supply module to the gas detection module in the form of pulses to control the power supply to the gas detection module;

[0047] The light-controlled wake-up module is electrically connected to the single-chip microcomputer and is used to transmit the power provided by the power supply module to the single-chip microcomputer based on the comparison result between the current light intensity and the preset light intensity threshold to control the state of the single-chip microcomputer;

[0048] The single chip microcomputer is connected to the gas detection module, the wireless transmission module and the display module respectively, and is used to receive the gas concentration in the air flow monitored by the gas detection module, transmit it to the display module for display, and transmit it to the wireless transmission module for transmission to the monitoring center;

[0049] The wireless transmission module is also used to receive control instructions sent by the monitoring center, so that the wireless transmission wind flow and gas monitoring system performs tasks according to the control instructions.

[0050] Specifically, in terms of power transmission, the power supply module, acting as a power supply module, is electrically connected to the pulse power-on control module, the light-controlled wake-up module, the wireless transmission module, and the display module to provide electrical energy. Furthermore, since the pulse power-on control module is also electrically connected to the gas detection module and transmits the power provided by the power supply module to the gas detection module in the form of pulses, the power used by the gas detection module is also provided by the power supply module. Similarly, since the light-controlled wake-up module is electrically connected to the microcontroller and transmits the power provided by the power supply module to the microcontroller based on the comparison between the current light intensity and the preset light intensity threshold, the power used by the microcontroller is also provided by the power supply module. In terms of data transmission, the microcontroller is separately connected to the gas detection module, the wireless transmission module, and the display module. The gas detection module monitors the gas concentration in the airflow and transmits it to the microcontroller. The microcontroller transmits the received gas concentration in the airflow to the display module for display and to the wireless transmission module. The wireless transmission module transmits the received gas concentration in the airflow to the monitoring center. In terms of its operating mechanism, the light-sensing element (photodiode or photoresistor, etc.) in the light-controlled wake-up module monitors the current light intensity in real time and compares it with a preset light intensity threshold. If the current light intensity is higher than the preset light intensity threshold, the microcontroller is controlled to enter the working state; if the current light intensity is lower than the preset light intensity threshold, the microcontroller is controlled to enter the sleep state. Furthermore, the pulse power-on control module pre-acquires the preset component power-on duty cycle corresponding to the gas detection module. Based on this preset component power-on duty cycle, the power provided by the power supply module is transmitted to the gas detection module in pulse form (i.e., power is transmitted to the gas detection module only for a portion of the time within a working cycle) to control the power supply to the gas detection module. Since the microcontroller and gas detection module do not need to operate continuously, system power consumption is reduced, thereby improving battery life. Furthermore, the wireless transmission module can also receive control commands from the monitoring center, enabling the wireless transmission windflow gas monitoring system to execute tasks according to the control commands.

[0051] It should be noted that the display module can use a 4-digit digital tube display element with low leakage current to reduce system power consumption. At the same time, other modules also need to use low-power devices with low leakage current.

[0052] Compared with the existing technology, the embodiment of the present application utilizes a pulse power-on control module to control the power supply of the gas detection module in the form of pulses, and at the same time utilizes a light-controlled wake-up module to control the working state of the microcontroller based on the comparison result between the current light intensity and the preset light intensity threshold, so that the system does not need to work in real time, reduces system power consumption, and thus improves battery life.

[0053] In one embodiment of the present application, preferably, the system also includes: a voltage conversion module; the voltage conversion module is electrically connected to the power supply module, and the power supply module is electrically connected to the pulse power-on control module, the light-controlled wake-up module, the wireless transmission module and the display module through the voltage conversion module, for converting the voltage provided by the power supply module into the operating voltage required by the pulse power-on control module, the light-controlled wake-up module, the wireless transmission module and the display module.

[0054] It should be noted that the voltage conversion module uses a high-efficiency chip to reduce system power consumption. Furthermore, the voltage conversion module converts the voltage provided by the power supply module into the stable operating voltage required by the pulse power-on control module, light-controlled wake-up module, wireless transmission module, and display module (which may also include the sound and light alarm module and remote control processing module). This ensures that each module can operate stably under different power supply module voltages, eliminating the need to limit the power supply module voltage and extending the power supply module's service life.

[0055] In one embodiment of the present application, preferably, the system also includes: a power supply control module, which is used to adjust the power parameters according to the working status of the pulse power-on control module or the light-controlled wake-up module or the wireless transmission module or the display module (which may also include an audio-visual alarm module or a remote control processing module).

[0056] Specifically, there are two situations in terms of power transmission. First, when there is no voltage conversion module, such as Figure 2 As shown, each power supply control module is electrically connected to the power supply module, and is communicated with the single-chip microcomputer, and the power supply module is electrically connected to the pulse power-on control module, the light control wake-up module, the wireless transmission module and the display module through each power supply control module (it may also include an audio and light alarm module and a remote control processing module); secondly, when a voltage conversion module is provided, such as Figure 3 As shown, each power supply control module is electrically connected to the voltage conversion module and communicatively connected to the single-chip microcomputer, and the voltage conversion module is electrically connected to the pulse power-on control module, the light control wake-up module, the wireless transmission module and the display module through each power supply control module (it can also include an audio and light alarm module and a remote control processing module).

[0057] In one embodiment of the present application, the system optionally further includes: an audible and visual alarm module; configured to receive an alarm instruction sent by the single chip computer and issue an alarm when the single chip computer determines that the current gas concentration exceeds a preset gas concentration threshold.

[0058] Specifically, there are three situations in terms of power transmission. First, when there is no voltage conversion module and no power supply control module, such as Figure 4As shown, the sound and light alarm module is electrically connected to the power supply module and is connected to the single chip microcomputer for communication. Figure 2 As shown, the sound and light alarm module is electrically connected to the power supply module through the power supply control module, and is connected to the single chip computer for communication. Figure 3 As shown, the power supply module, voltage conversion module, power supply control module, and sound and light alarm module are electrically connected in sequence, and the sound and light alarm module is connected to the microcontroller. When the microcontroller determines that the current gas concentration exceeds the preset gas concentration threshold, it sends an alarm command to the microcontroller. Upon receiving the alarm command, the microcontroller triggers an alarm to remind on-site personnel to take appropriate measures to ensure safe production.

[0059] In one embodiment of the present application, optionally, the system further includes: a remote control processing module; configured to receive remote control instructions sent by a user, so that the wireless transmission wind flow and gas monitoring system performs tasks according to the remote control instructions.

[0060] Specifically, there are three situations in terms of power transmission. First, when there is no voltage conversion module and no power supply control module, such as Figure 4 As shown, the remote control processing module is electrically connected to the power supply module and is connected to the single chip microcomputer for communication. Figure 2 As shown, the remote control processing module is electrically connected to the power supply module through the power supply control module, and is connected to the single chip microcomputer for communication. Figure 3 As shown, the power supply module, voltage conversion module, power supply control module, and remote control processing module are electrically connected in sequence, and the remote control processing module is connected to the microcontroller for communication. Users can remotely operate and control the wireless transmission airflow and gas monitoring system through the remote control processing module, thereby improving the system's convenience and practicality.

[0061] In one embodiment of the present application, preferably, the gas detection module can use a laser methane element to improve detection accuracy.

[0062] In one embodiment of the present application, preferably, the single chip microcomputer can adopt a low-power single chip microcomputer to reduce system power consumption.

[0063] In one embodiment of the present application, the preset component power-on duty cycle can preferably be set to a duty cycle T of 1s and a power-on operating time of 0.4s. It should be noted that the smaller the component power-on duty cycle, the less power it consumes, but the worse the operating stability. Therefore, the preferred value should be selected based on actual conditions.
