[0024] The embodiments of the present invention described below are generally only some embodiments and not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of patent protection.

[0025] The terms "comprising," "including," and any variations thereof in this specification, the corresponding claims, and related sections are intended to cover non-exclusive inclusion. Other related terms and units can be reasonably interpreted based on the relevant content provided in this specification.

[0026] Figure 1 This is a structural schematic diagram of the intelligent building engineering quality detection device of this utility model. Figure 1 As shown, the intelligent testing device for building engineering quality provided by this utility model includes a digital testing instrument kit 10 and a field data acquisition terminal 20.

[0027] The digital inspection instrument kit 10 includes various digital inspection instruments, such as a digital straightedge, digital rangefinder, digital tape measure, digital square, digital vibration meter, digital crack width gauge, digital thickness gauge, and digital rebound hammer. Each digital inspection instrument is used to inspect the quality of its corresponding type of building project and can digitize the inspection data and transmit it to the on-site data acquisition terminal 20 via Bluetooth. In this embodiment, the digital straightedge is used to measure the verticality and flatness of the building surface, the digital rangefinder is used to measure the length of the building space, and the digital rebound hammer is used to measure the concrete strength, etc. These digital inspection instruments are all equipped with built-in Bluetooth modules, enabling wireless data transmission.

[0028] The on-site data acquisition terminal 20 is a portable computer, mainly including a processor 21, a memory 22, an input device 23, an output device 24, a communication module 25, a power module 26, and an environmental sensor. These components are coupled together through a circuit board to form a complete functional system.

[0029] The processor 21 uses an ARM Cortex-M4 microcontroller, which features low power consumption and high performance, meeting the needs of data acquisition and processing. The memory 22 includes 512KB of static random access memory (SRAM) and 4MB of flash memory. The SRAM stores temporary data during program execution, while the flash memory stores program code and long-term stored data. The input device 23 uses control buttons, allowing users to perform operations such as power on / off and mode switching. The output device 24 uses LED status indicators to display the device's operating status, Bluetooth connection status, and other information. The power module 26 uses a rechargeable lithium battery or commercially available alkaline batteries to ensure the device can operate for extended periods in the field.

[0030] The communication module 25 employs a Bluetooth module, specifically a dual-mode Bluetooth module using the nRF52840 Bluetooth chip. This Bluetooth module supports dual-mode Bluetooth technology, enabling communication with both the various digital testing instruments in the digital testing instrument kit 10 and the mobile phone 30 of the on-site user. Specifically, the on-site data acquisition terminal 20 uses this Bluetooth module to connect to the various digital testing instruments in the digital testing instrument kit 10 as a central device using Bluetooth Low Energy transmission, and also as a peripheral device to connect to the mobile phone 30 using either classic Bluetooth transmission or Bluetooth Low Energy transmission. This dual-role design allows the on-site data acquisition terminal 20 to effectively act as a data relay station.

[0031] The environmental sensors include a pressure sensor 271 and a temperature sensor 272. The pressure sensor 271 has a detection resolution of ≤15 Pa, which is 12 Pa in this embodiment, enabling it to accurately measure pressure changes in the building environment. The temperature sensor 272 is used to measure the ambient temperature, providing a temperature reference for the detection data.

[0032] The mobile phone 30 is a smartphone with a dedicated application for building engineering quality inspection installed. It has a built-in GNSS module for positioning. The sensing elements (barometric pressure sensor 271 and temperature sensor 272) used in the on-site data acquisition terminal 20 are those not present in the mobile phone 30. This design avoids functional duplication and reduces costs.

[0033] In actual operation, the on-site data acquisition terminal 20 receives the detection data from the corresponding digital detection instruments in the digital detection instrument kit 10, and transmits these detection data and environmental data collected by environmental sensors to the mobile phone 30 via Bluetooth. Then, the data is processed, stored and analyzed by the special application for building engineering quality inspection.

[0034] like Figure 2 and Figure 3 As shown, the digital testing instrument kit 10 has an instrument integrated housing 11, and the on-site data acquisition terminal 20 is installed on the instrument integrated housing 11 (specifically, it is installed in the on-site data acquisition terminal housing on the back of the instrument integrated housing 11). The instrument integrated housing 11 has multiple instrument storage areas inside for storing different digital testing instruments, and the overall structure is compact and easy to carry.

[0035] The method of using the intelligent building construction quality inspection device is as follows: First, the user turns on the on-site data acquisition terminal 20 and ensures that it establishes a Bluetooth connection with the mobile phone 30; then, the user takes out the digital inspection instrument to be used, such as the digital ruler 11, from the instrument integration box 11 and turns it on; the digital ruler 11 will automatically establish a Bluetooth connection with the on-site data acquisition terminal 20; next, the user uses the digital ruler 11 to conduct building construction quality inspection, and the inspection data is automatically transmitted to the on-site data acquisition terminal 20; after receiving the data, the on-site data acquisition terminal 20 will simultaneously collect data from environmental sensors and transmit all data to the mobile phone 30 via Bluetooth; finally, the dedicated building construction quality inspection application on the mobile phone 30 processes, analyzes, and stores the received data to generate an inspection report.

[0036] The dedicated application for building construction quality inspection on the 30 mobile phone can record GNSS positioning data and environmental data, saving this positioning data along with the inspection data to form a complete inspection record. The GNSS positioning data can determine the planar coordinates at the time of inspection, and combined with the air pressure value, the floor height at the time of inspection can be accurately determined, thus comprehensively verifying the data collection location.

[0037] This utility model provides an intelligent inspection device for building engineering quality. By combining digital inspection instruments with a field data acquisition terminal, it achieves automatic data collection and transmission. By integrating the field data acquisition terminal with a mobile phone, it fully utilizes the computing power and widespread availability of mobile phones, reducing the configuration requirements and costs of the field data acquisition terminal. Simultaneously, by collecting environmental parameters through environmental sensors, it improves the accuracy and reliability of the inspection data. The overall solution has advantages such as low cost, good portability, and ease of commercialization.

[0038] The foregoing has described the relevant content of this utility model. Those skilled in the art will be able to implement this utility model based on these descriptions. All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of this utility model.
