Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0038] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0040] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides an intelligent monitoring dust removal vehicle, including:

[0043] Trolley 1;

[0044] The dust intelligent monitoring box 2 is installed on the trolley 1 and has a dust detection circuit inside;

[0045] A dust box 3 is provided on the trolley 1 and has a dust storage box 31 therein;

[0046] The fan 4 is arranged in the dust box 3, and its air outlet is connected to the dust storage box 31;

[0047] A dust collection duct 41 has one end connected to the air inlet of the fan 4 and the other end passing through the dust box 3 and extending out of the dust box 3 with the opening facing downward;

[0048] The display screen 5 is connected to the dust detection circuit to display dust detection data of the dust detection circuit.

[0049] It should be understood that the fan 4 can be a dedicated fan 4 for a vacuum cleaner (dust collection device), and the corresponding model can be selected according to conventional solutions and actual needs; the dust detection circuit can also be a conventional solution, or the solution of the following embodiment can be adopted.

[0050] During operation, as a worker pushes cart 1 through the workshop, the dust detection circuit detects the dust content in the surrounding environment and transmits the dust detection data to display screen 5. The worker views the dust detection data on display screen 5 to determine whether the dust content exceeds the standard (whether the standard is exceeded is determined based on the actual dust content requirements of the workshop). If so, the worker activates fan 4. For ease of operation, a start button for fan 4 can be located next to display screen 5. Once activated, fan 4 draws dust-laden air from the surrounding environment (particularly the floor) into dust storage box 31 through dust collection duct 41 until the dust content is within the standard. This dust removal principle is consistent with that of existing vacuum cleaners and will not be further described here. After dust removal, fan 4 can be turned off, reducing its operating time and thus saving costs to a certain extent.

[0051] In practical applications, a processor and memory can be added. The processor is connected to the fan 4, display screen 5, memory, and dust detection circuit. The memory stores the workshop's dust content requirement, i.e., the dust content threshold. The dust detection circuit transmits dust detection data to the processor and displays it on display screen 5 (making it easy for staff to review the dust detection data and check for processor malfunctions). The processor retrieves the dust content threshold stored in the memory and compares it with the dust detection data. If the dust detection data exceeds the dust content threshold, the processor controls the fan 4 to start. If the dust detection data is less than or equal to the dust content threshold while the fan 4 is operating, the processor controls the fan 4 to stop. Thus, the processor and memory achieve automatic dust removal, eliminating the need for manual judgment. The processor can be a chip with a comparison function, and the memory can be a chip with a storage function. Of course, the processor and memory can also be chips with both comparison and storage functions.

[0052] In some embodiments, the dust collection duct 41 includes a left tube 411 and a right tube 412 , which extend from the left and right sides of the dust box 3 respectively. There are multiple left tubes 411 and multiple right tubes 412 .

[0053] In some embodiments, the plurality of left tubes 411 are arranged equidistantly.

[0055] In some embodiments, the dust suction duct 41 further includes a middle pipe 413 , which vertically penetrates the bottom of the dust box 3 and the bottom plate of the trolley 1 downward.

[0060] In some embodiments, the dust detection circuit also includes a GPS receiver U3, an indicator light L1 and a resistor R7, pin 2 of the GPS receiver U3 is connected to pin 8 of the CPU chip U1, pin 5 of the GPS receiver U3 is connected to the second fixed end of the display power switch SW, pin 4 of the GPS receiver U3 is connected to the negative pole of the indicator light L1 and then grounded, the positive pole of the indicator light L1 is connected to one end of the resistor R7, and the other end of the resistor R7 is connected to pin 10 of the CPU chip U1.

[0061] In some embodiments, the dust detection circuit further includes a temperature and humidity sensor U5 , and pins 2 and 1 of the temperature and humidity sensor U5 are connected to pins 12 and 17 of the CPU chip U1 in a one-to-one correspondence.

[0062] In some embodiments, the dust detection circuit also includes a gas sensor U6, a resistor R51 and a resistor R52, pin 4 of the gas sensor U6 is connected to the second fixed end of the display power switch SW, pin 2 of the gas sensor U6 is connected to one end of the resistor R51, and the other end of the resistor R51 is connected to pin 25 of the CPU chip U1 and the grounded resistor R52.

[0066] In practice, the CPU chip U1 can be used directly as the processor, and the SD card reader U2 and corresponding SD card can be used as the memory.

Adding a corresponding gas purification box (with built-in gas absorbents) to the cart 1 can simultaneously remove dust and purify these gases, optimizing the air quality in the workshop.

[0067] The dust sensor U4 transmits the dust detection data to the CPU chip U1. The CPU chip U1 reads the dust content threshold stored in the SD card in the SD card reader U2 and compares it with the dust detection data. If the dust detection data is greater than the dust content threshold, the CPU chip U1 controls the fan 4 to start, and controls the transistor Q3 to turn on, and the buzzer and / or display light work; when the fan 4 is working, the dust detection data is less than or equal to the dust content threshold, and the CPU chip U1 controls the fan 4 to stop.
