[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0042] like Figure 1-4 As shown, the present invention provides a green building environmental monitoring system, which includes a mobile vehicle body 1, multiple lifting mechanisms 2, an environmental data acquisition module, and a central control module 6.

[0043] Multiple lifting mechanisms 2 are mounted on the mobile vehicle body 1, and each lifting mechanism 2 is equipped with a drive unit that can move linearly along the vertical direction of the mobile vehicle body 1; the environmental data acquisition module includes an air quality acquisition module 3, an acoustic and optical acquisition module 4, and a thermal environment acquisition module 5. The air quality acquisition module 3, the acoustic and optical acquisition module 4, and the thermal environment acquisition module 5 are respectively mounted on the drive unit of each lifting mechanism 2, and their detection height is adjusted by the linear movement of the drive unit; the central control module 6 is mounted on the mobile vehicle body 1 and is electrically connected to the multiple lifting mechanisms 2, the air quality acquisition module 3, the acoustic and optical acquisition module 4, and the thermal environment acquisition module 5, and is used to control the movement of the drive unit of the lifting mechanism 2 and to receive and process the collected environmental data.

[0044] Specifically, the mobile vehicle body 1 is a mobile robot that can walk autonomously. The surface of the vehicle body is treated with anti-rust treatment, such as spraying anti-corrosion paint or using galvanizing process, which effectively prevents rust and corrosion in the harsh environment of the construction site and extends its service life. Multiple lifting mechanisms 2 are evenly distributed on the mobile vehicle body. The specific number can be reasonably configured according to the actual detection needs and the size of the vehicle body, generally no less than 3, which can ensure that the environmental data acquisition module can perform comprehensive and uniform detection at different heights, thereby improving the accuracy of detection.

[0045] It should be noted that by moving the mobile vehicle 1 to different collection points in the construction area, and using the lifting mechanism 2 to adjust the detection height, the central control module 6 issues commands to control the drive unit of the lifting mechanism 2 to perform linear movement, thereby raising the collection modules of different functions to the preset optimal measurement height. After each collection module reaches the appropriate height, the air quality collection module 3 collects indicators such as pollutants in the air, the sound and light collection module 4 collects data such as noise and light intensity at the construction site, and the thermal environment collection module 5 measures thermal environment parameters such as temperature and humidity at the construction site. These collected environmental data are transmitted to the central control module 6 in real time. The central control module 6 centrally processes and analyzes the received data, thereby achieving comprehensive and effective monitoring of the construction environment.

[0046] like Figure 5 As shown, in a preferred embodiment, the lifting mechanism 2 in this embodiment includes an electric push rod 21 and a motor drive chip 22. The control input end of the electric push rod 21 is electrically connected to the output end of the motor drive chip 22, and the input end of the motor drive chip 22 is electrically connected to the input end of the central control module 6. The central control module 6 controls the linear movement of the drive part of the electric push rod 21.

[0047] It should be noted that, based on the coordinated operation of the electric actuator 21 and the motor drive chip 22, the central control module 6 sends control commands to the motor drive chip 22. After receiving the commands, the motor drive chip 22 converts them into signals suitable for the control of the electric actuator 21 and transmits them to the control input terminal of the electric actuator 21 through its output terminal. According to the received signals, the electric actuator 21 drives its internal drive unit to perform linear motion, thereby raising the air quality acquisition module 3, the sound and light acquisition module 4, and the thermal environment acquisition module 5 to the preset optimal measurement height to meet different detection requirements, ensure that the acquisition modules can accurately reach the specified height, and improve the accuracy and reliability of the detection data.

[0048] like Figure 6 As shown, the air quality acquisition module 3 in this embodiment includes a carbon dioxide sensor 31 and a particulate matter sensor 32. The output terminals of the carbon dioxide sensor 31 and the particulate matter sensor 32 are electrically connected to the input terminal of the central control module 6, respectively. The carbon dioxide sensor 31 is used to detect the concentration of carbon dioxide in the air, and the particulate matter sensor 32 is used to detect at least one of PM2.5 and PM10 in the air.

[0049] It should be noted that the carbon dioxide sensor 31 can detect in real time whether the carbon dioxide content in the air exceeds the standard, and the particulate matter sensor 32 can detect harmful particulate matter such as PM2.5 and PM10. The accurate detection of their concentration is conducive to assessing the degree of air pollution at the construction site, thus realizing comprehensive and real-time monitoring of air quality.

[0050] like Figure 7 and 8 As shown, the sound and light acquisition module 4 in this embodiment includes a noise sensor 41, an illuminance sensor 42, and an acquisition communication unit 43. The output terminals of the noise sensor 41 and the illuminance sensor 42 are electrically connected to the input terminal of the acquisition communication unit 43. The noise sensor 41 is used to acquire ambient noise, the illuminance sensor 42 is used to acquire ambient illuminance, and the output terminal of the acquisition communication unit 43 is communicatively connected to the input terminal of the central control module 6.

[0051] It should be noted that the noise sensor 41 can collect noise data at the construction site, avoiding adverse effects on surrounding residents and the environment. The illuminance sensor 42 collects air illuminance information, which can provide a basis for the rational arrangement of construction lighting, ensuring that the construction area has appropriate light intensity, improving construction efficiency and quality, and avoiding energy waste caused by excessive lighting. The acquisition and communication unit 43 realizes the communication between the noise sensor 41, the illuminance sensor 42 and the central control module 6. The acquisition and communication unit 43 is an R485 communication chip.

[0052] like Figure 9 As shown, the thermal environment acquisition module 5 in this embodiment includes a black sphere temperature sensor 51, a temperature and humidity sensor 52, a decoupling unit 53, an airflow sensor 54, and a first signal conditioning unit 55. The output of the black sphere temperature sensor 52 is electrically connected to the input of the central control module 6 and is used to acquire radiant temperature. The output of the temperature and humidity sensor 52 is also electrically connected to the input of the central control module 6 and is used to acquire ambient airflow values. The positive power supply terminal of the temperature and humidity sensor 52 is electrically connected to one end of the decoupling unit 53, and the negative power supply terminal of the temperature and humidity sensor 52 is grounded to the other end of the decoupling unit 53. The decoupling unit 53 is used for power decoupling. The output of the airflow sensor 54 is electrically connected to the input of the first signal conditioning unit 55, which is used to filter the temperature and humidity signals acquired by the temperature and humidity sensor 52. The output of the first signal conditioning unit 55 is also electrically connected to the input of the central control module 6.

[0053] The first signal conditioning unit 55 and the second signal conditioning unit 74 both include a capacitor C1 and a resistor R1. The output terminal of the temperature and humidity sensor 52 is electrically connected to the capacitor C1 and the resistor R1 respectively. The other end of the capacitor C1 is grounded to the common negative terminal of the power supply of the temperature and humidity sensor 52, and the other end of the resistor R1 is electrically connected to the input terminal of the central control module 6.

[0054] It should be noted that when the temperature and humidity sensor 52 outputs a signal, capacitor C1 filters the high-frequency noise in the signal and bypasses it to ground, while resistor R1 plays the role of current limiting and impedance matching, so that the signal can be transmitted to the central control module 6 stably and accurately.

[0055] The decoupling unit 53 includes capacitors C2 and C3. The positive terminal of the power supply of the temperature and humidity sensor 52 is electrically connected to capacitors C2 and C3 and the power supply terminal, respectively. The negative terminal of the power supply of the temperature and humidity sensor 52 is electrically connected to the other end of capacitors C2 and C3, respectively, and is grounded together.

[0056] It should be noted that during the power supply process, there will be high-frequency noise and transient interference in the power supply. Capacitors C2 and C3 can quickly absorb and release charges, bypassing the noise and interference to ground, providing a stable and clean power supply for the temperature and humidity sensor 52, and ensuring the accuracy of its data collection.

[0057] like Figure 10 As shown, this embodiment also includes an electromagnetic environment monitoring module 7, which includes a low-frequency electric field sensor 71, a high-frequency electric field sensor 72, a magnetic field sensor 73, and multiple second signal conditioning units 74. The low-frequency electric field sensor 71, the high-frequency electric field sensor 72, and the magnetic field sensor 73 are electrically connected to the input terminals of their respective second signal conditioning units 74 to detect the magnetic field radiation in the environment. The output terminals of each second signal conditioning unit 74 are electrically connected to the corresponding input terminals of the central control module 6.

[0058] It should be noted that the electromagnetic environment monitoring module 7, through the low-frequency electric field sensor 71, the high-frequency electric field sensor 72, and the magnetic field sensor 73, can simultaneously detect low-frequency electric field, high-frequency electric field, and magnetic field radiation, realizing comprehensive multi-frequency monitoring of the electromagnetic environment at the construction site; this facilitates the timely detection of various electromagnetic interference sources that may exist at the construction site, ensuring the health of construction personnel and the normal operation of construction equipment.

[0059] like Figure 11 As shown, this embodiment also includes a voltage detection module 8, which includes a voltage divider unit 81 and a filter unit 82. One end of the voltage divider unit 81 is electrically connected to the power supply terminal, and the other end is grounded with the filter unit 82. The input terminal of the central control module 6 is electrically connected to the common terminal of the voltage divider unit 81 and the filter unit 82, and is used to collect the voltage signal after voltage division and filtering.

[0060] Specifically, the voltage detection module 8 includes resistors R2 and R3 and capacitor C4. The input terminal of the central control module 6 is electrically connected to one end of resistors R2, R3 and C4 respectively. The other end of resistor R2 is electrically connected to the power supply terminal, and the other end of resistor R3 and the other end of capacitor C4 are grounded together.

[0061] It should be noted that the voltage divider circuit composed of resistors R2 and R3 reduces the high voltage of the power supply by a certain proportion, making the output voltage value compatible with the input voltage range of the central control module 6. This effectively avoids potential damage caused by directly connecting high voltage to the central control module 6, ensuring the safe operation of the central control module 6 and the stable operation of the entire green building environmental monitoring system. The filter unit composed of resistor R3 and capacitor C4 can efficiently filter out AC interference components in the power supply voltage, making the acquired voltage signal purer and more stable, greatly improving the accuracy and reliability of voltage detection.

[0062] like Figure 12 As shown, this embodiment also includes a power supply module 9. The power supply terminals of the air quality acquisition module 3, the sound and light acquisition module 4, the thermal environment acquisition module 5, and the electromagnetic environment monitoring module 7 are all electrically connected to the output terminal of the power supply module 9 for power supply.

[0063] In this embodiment, the power supply module 9 is a voltage regulator IC chip, and its chip model is AMS1117-3.3.

[0064] This embodiment also includes a host computer 10 and a wireless communication module 11. The host computer 10 is connected to the central control module 6 through the wireless communication module 11.

[0065] The wireless communication module 11 in this embodiment can be a type of 4G, 5G, or WIFI wireless communication.

[0066] Working principle:

[0067] The mobile vehicle 1 moves to different data collection points in the construction area. The central control module 6 issues commands, which are transmitted to the electric push rod 21 via the motor drive chip 22. This push rod 21 moves linearly, raising the carbon dioxide sensor 31, particulate matter sensor 32, noise sensor 41, illuminance sensor 42, black sphere temperature sensor 51, and electromagnetic environment monitoring module 7 to a preset height. Each data collection module collects air quality, sound and light, thermal environment, and electromagnetic environment data, which are then transmitted to the central control module 6. Simultaneously, the voltage detection module 8 provides a stable voltage signal to the central control module 6 through resistor voltage division and capacitor filtering. The power supply module 9 supplies power to each data collection module. After centrally processing and analyzing the data, the central control module 6 transmits the data to the host computer 10 via the wireless communication module 11, achieving comprehensive and effective monitoring of the construction environment.
