[0004] However, existing measuring devices require manual measurement, and electrical design is not limited to one place within a building, often requiring multiple measurements, making manual measurement inefficient. Therefore, we provide a measuring device and its measurement method for building electrical design. Summary of the Invention

[0005] The purpose of this invention is to provide a measuring device and method for building electrical design, in order to solve the problems mentioned in the background art, that existing measuring devices require manual measurement, and that electrical design is not limited to one place in a building and often requires multiple points of measurement, making manual measurement inefficient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a measuring device for building electrical design, comprising a terminal housing, an upper cover mounted on the top of the terminal housing, and a terminal display screen installed inside the upper cover; a lower cover mounted on the bottom of the terminal housing; a buckle provided at the front of the upper end of the upper cover; a slot provided above the front end of the terminal housing; a handle rotatably connected to the front end of the terminal housing; an embedded keyboard provided inside the upper surface of the terminal housing; a terminal maintenance cover provided at the rear end of the embedded keyboard, and the four corners of the terminal maintenance cover connected to the terminal housing by screws; multiple placement slots provided inside the bottom surface of the terminal housing; and measuring mechanisms provided inside the placement slots.

During testing, multiple measuring mechanisms are distributed in the room to be tested, enabling synchronous measurement to improve measurement efficiency. Measurement results can be wirelessly transmitted to the terminal for convenient data management and subsequent electrical design.

[0007] Preferably, the measuring mechanism includes a base, a movable shaft collar is mounted on the upper end of the base, and the inner wall of the movable shaft collar is provided with several toothed grooves. A fixed shaft collar is rotatably connected to the lower part of the movable shaft collar, and the fixed shaft collar is fixedly connected to the base. A control module, a power module, and a transverse drive motor are installed inside the base. A gear is mounted on the output end of the transverse drive motor, and the transverse drive motor is connected to the movable shaft collar through gear meshing with the toothed grooves on the inner wall of the movable shaft collar. A top cover is mounted on the upper surface of the movable shaft collar, and a support is mounted on the upper end of the top cover. A measuring head is rotatably connected inside the support, and a laser rangefinder sensor is mounted on the end of the measuring head. The device has a belt drive cover installed on one side of the support, and a longitudinal drive motor is installed at one end of the belt drive cover. The output end of the longitudinal drive motor is connected to the measuring head through the belt drive mechanism inside the belt drive cover. Handles are installed on both sides of the support. An anti-winding reel is provided at the upper end of the power module. During measurement, because the measuring head is designed to rotate in both vertical and horizontal directions, the wire harness is connected to the power module through the anti-winding reel. The anti-winding reel is equipped with a spring clip, which can pull out the wire harness as the measuring head rotates. When the measuring head is reset, the spring clip can wind up the excess wire harness, thereby avoiding winding.

[0008] Preferably, the control module within the base includes a microcontroller chip, a motor control module, a wireless data transmission module, and a GPS positioning module. A gyroscope module is installed inside the measuring head. The output of the microcontroller chip is electrically connected to the inputs of the horizontal and vertical drive motors via the motor control module. The outputs of the GPS positioning module, laser rangefinder, and gyroscope module are all electrically connected to the input of the microcontroller chip. The output of the power supply module is electrically connected to the input of the microcontroller chip. The housing integrates a terminal and multiple measuring mechanisms. During testing, these mechanisms are distributed throughout the testing room, enabling synchronous measurement and improving efficiency. Measurement results can be wirelessly transmitted to the terminal for convenient data management and subsequent electrical design.

[0009] Preferably, a positioning block is provided at the middle position of the lower end of the base, a charging slot is provided inside the positioning block, feet are installed at the four corners of the lower end of the base, a positioning groove is provided on the bottom surface of the placement slot, a charging connector is provided inside the positioning groove, and foot grooves are provided around the positioning groove.

[0010] Preferably, the rear end of the upper cover and the front end of the lower cover are rotatably connected to the terminal housing via damping hinges. The front end of the upper cover and the rear end of the lower cover are each equipped with a locking block. The front end of the terminal housing is equipped with a buckle above it and the rear end is equipped with a buckle below it. The terminal housing is engaged with the locking blocks on the upper and lower covers via the buckles.

[0011] Preferably, multiple heat dissipation slots are provided on both sides of the terminal inspection cover, and a dustproof mesh is provided inside the heat dissipation slots.

[0012] Preferably, the inner wall of the lower end cover is provided with a mating groove, and the bottom surface of the terminal box is provided with a raised edge.

[0013] Preferably, a charging port is provided at the rear end of the terminal housing.

[0014] Preferably, pads are installed at the four corners of the outer walls of the upper and lower end covers, and rubber pads are provided at the ends of the pads.

[0015] Preferably, a measurement method for a measuring device used in building electrical design includes the following steps:

[0016] Step 1: First, open the lower cover of the terminal box and use the handle to take out the measuring mechanisms placed in the slots one by one. After taking them out, place the multiple measuring mechanisms in the room to be tested.

[0017] Step 2: After the measuring mechanism is set up, place the terminal box flat on the table with the lower end cover facing down, open the upper end cover, and start the terminal through the embedded keyboard. Use the terminal to remotely connect with the wireless data transmission module of each measuring mechanism, and send signals to the measuring mechanism to drive the operation of each measuring mechanism.

[0018] Step 3: When the measuring mechanism is running, its internal microcontroller chip drives the longitudinal and transverse drive motors through the motor control module. The transverse drive motor drives the gear at the output end to rotate, which meshes with the tooth groove on the inner wall of the moving shaft ring, driving the moving shaft ring and the measuring head on the top cover to rotate horizontally. Relying on the laser range sensor on the measuring head, the horizontal distance in space is scanned. The longitudinal drive motor drives the measuring head to rotate longitudinally through the belt drive mechanism in the belt drive cover. Relying on the laser range sensor, the distance is detected at different longitudinal tilt angles. During the detection process, the gyroscope module in the measuring mechanism can detect the tilt angle. Based on the known horizontal distance and tilt angle, the microcontroller chip can further calculate the vertical height in space using trigonometric function formulas, thereby realizing a comprehensive scanning measurement of space.

[0019] Step 4: The test data from each measuring agency is fed back to the terminal via a wireless data transmission module. The terminal display shows the data intuitively. The measuring agency has a built-in GPS positioning module, which makes it easy to confirm the distribution of each testing room, thereby completing the building testing work simultaneously.

[0020] Step 5: After the measurement is completed, collect the measuring devices from each room and put them back into the placement slot of the terminal box. When placing them, make sure that the charging slot at the bottom of the measuring device is connected to the charging connector in the placement slot. Utilize the charging port on the outer wall of the terminal box to connect to the power socket to achieve centralized charging of multiple measuring devices.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) The device of the present invention adopts a portable design with flip-top structure at both the top and bottom, which correspond to the detection mechanism placement compartment and the terminal respectively. The box integrates the terminal and multiple measuring mechanisms. During the detection, multiple measuring mechanisms are distributed in the room to be tested, which can realize synchronous measurement to improve measurement efficiency. The measurement results can be summarized to the terminal through wireless data transmission, which facilitates data management for subsequent electrical design. This solves the problem that existing measuring devices need to be manually measured, and electrical design is not limited to one place in the building, often requiring multiple points of measurement, which is inefficient when done manually.

[0023] (2) When the measuring mechanism is running, its internal microcontroller chip drives the longitudinal drive motor and the transverse drive motor through the motor control module. The transverse drive motor drives the gear at the output end to rotate, which meshes with the tooth groove on the inner wall of the moving shaft ring, driving the moving shaft ring and the measuring head on the top cover to rotate horizontally. Relying on the laser distance sensor on the measuring head, the horizontal distance in the space is scanned. The longitudinal drive motor can drive the measuring head to rotate longitudinally through the belt drive mechanism in the belt drive cover. Relying on the laser distance sensor, the distance is detected at different longitudinal tilt angles. During the detection process, the gyroscope module in the measuring mechanism can detect the tilt angle. Based on the known horizontal distance and tilt angle, the microcontroller chip can further calculate the vertical height in the space through trigonometric function formulas, thereby realizing the comprehensive scanning measurement of the space. The detection data of each measuring mechanism is fed back to the terminal through the wireless data transmission module, and the data is displayed intuitively on the terminal display screen. The measuring mechanism has a built-in GPS positioning module, which makes it easy to confirm the distribution location of each detection room, thereby completing the detection work in various parts of the building simultaneously.

[0024] (3) The terminal of the present invention has a built-in power supply, which not only ensures its own power supply, but also acts as a relay device to provide charging power to the measuring mechanism after the measuring mechanism is plugged in. When the measuring mechanism is stored in the placement slot, there is a charging slot on its bottom surface that can be plugged into the charging connector in the placement slot. At this time, by supplying power to the terminal, multiple measuring mechanisms can be charged synchronously in a centralized manner, which improves convenience.

[0025] (4) During measurement, the measuring head is designed to rotate in both vertical and horizontal directions. Therefore, the wire harness is connected to the power module through an anti-winding reel. The anti-winding reel is equipped with a spring clip, which can pull out the wire harness as the measuring head rotates. When the measuring head is reset, the spring clip can wind up the excess wire harness, thereby avoiding winding and ensuring the service life of the measuring mechanism. Attached Figure Description

Step 3: When the measuring mechanism (19) is running, its internal microcontroller chip (21) drives the longitudinal drive motor (1909) and the transverse drive motor (1913) through the motor control module (22). The transverse drive motor (1913) drives the gear (1914) at the output end to rotate, which meshes with the tooth groove on the inner wall of the moving shaft ring (1903) to drive the moving shaft ring (1903) and the measuring head (1906) on the upper cover (1904) to rotate horizontally. Relying on the laser range sensor (1907) on the measuring head (1906), the measurement is realized within the space. The horizontal distance is scanned, while the longitudinal drive motor (1909) can drive the measuring head (1906) to rotate longitudinally through the belt drive mechanism in the belt drive cover (1908). The distance detection under different longitudinal tilt angles is achieved by relying on the laser range sensor (1907). During the detection process, the gyroscope module (24) in the measuring mechanism (19) can detect the tilt angle. Based on the known horizontal distance and tilt angle, the single-chip microcomputer (21) can further calculate the vertical height in the space through trigonometric function formulas, thereby realizing the comprehensive scanning measurement of the space. Step 4: The detection data of each measuring unit (19) is fed back to the terminal through the wireless data transmission module (23), and the data is displayed intuitively on the terminal display screen (11). The measuring unit (19) has a built-in GPS positioning module (25) to facilitate the confirmation of the distribution location of each detection room, thereby completing the building detection work simultaneously. Step 5: After the measurement is completed, collect the measuring mechanisms (19) in each room and put them back into the placement slot (18) of the terminal box (1). When placing them, make the charging slot (1911) at the bottom of the measuring mechanism (19) connect with the charging connector (183) in the placement slot (18). Use the charging port (17) on the outer wall of the terminal box (1) to connect with the power socket to realize the centralized charging of multiple measuring mechanisms (19).
