It will be readily appreciated that the multi-function digital measuring tape also includes a power supply module to provide power for the operation of the laser ranging module 20, the inclination measuring module 30 and the main control module 40. The power supply module can select a solar power generation module, a storage battery and/or a dry battery.
Fig. 3 is a schematic structural view of the measuring tape body according to the present invention, and the number of the laser ranging modules 20 is plural to measure the flatness of the building. In fig. 3, the laser ranging modules 20 are disposed at the side of the measuring tape body 10, and the number thereof is 4. The laser ranging modules 20 are uniformly arranged on the side of the measuring tape body 10 at intervals.
In the embodiment shown in fig. 2, the tilt angle measuring module 30 is a two-axis tilt angle sensor, which is disposed on the measuring tape body 10 to measure the verticality of the building.
As an embodiment of the present invention, the measuring tape measures the flatness of the building, and when the distance between the measuring tape and the building is smaller than a preset value L, the main control module 40 sends a warning message and determines that the current measurement data is invalid. In the implementation shown in fig. 1, the preset value L is 300 mm. Specifically, the measuring scale has a distance reminding function of measuring the first scale, and when the flatness is detected, the first scale function is set, and when the distance between the measuring scale and the side surface or the ground is less than 300 millimeters, a warning prompt is sent out, so that the current test data is invalid and needs to be measured again.
As another embodiment of the present invention, the measuring tape measures the perpendicularity of the building, and when an included angle between the measuring tape and the plumb direction exceeds a preset value θ, the main control module 40 sends warning information and determines that the current measurement data is invalid. In the implementation shown in fig. 1, the preset value θ is 10 °. Specifically, the measuring tape has a handheld perpendicularity deflection angle reminding function. When measuring verticality, a two-axis tilt angle sensor is arranged at the middle position of the measuring scale and parallel to the vertical direction of the measuring scale, and the included angle between the sensitive axis of the two-axis tilt angle sensor and the gravitational acceleration in the vertical direction is measured. When the included angle is smaller than 10 degrees, the current perpendicularity is corrected by programming the main control module to subtract or add the included angle value; when the included angle is larger than 10 degrees, the main control board can not correct, but directly sends out warning prompt, so that the current test data is invalid and needs to be measured again.
In fig. 1, the display module 50 is disposed at a middle position of the top of the measuring tape body 10 to display the measurement data of the measuring tape in real time. The measurement data further comprises geographical location information, measurement time information and remark information.

In fig. 2, the measuring tape further includes an alarm module 80, which is connected to the main control module 40, and when the measuring tape has invalid measurement data, the alarm module 80 sends an alarm signal. The warning module 80 may be a sound and light alarm device that can generate a "measurement invalid" voice or emit a "drip" continuous sound to alert field measurement personnel. In some embodiments, the alert module 80 may also be a vibrating device. It directly sends out a vibration signal to warn the measuring staff. This is because the environment is noisy on the construction site, and ordinary voice cannot accurately warn the measuring staff.
As an embodiment of the present invention, the mobile terminal 70 includes a smart phone or a PC, which shares the measurement data to a cloud in real time, and the cloud shares the measurement data to other mobile terminals 70, as shown in fig. 5. In fig. 5, the cloud may share the measurement data of the measuring tape to other mobile terminals 70, which may be smart phones or PCs.
As another embodiment of the present invention, the measuring tape body 10 is more than one in number, and is hinged as a single body; the adjacent measuring tape bodies 10 are in the same plane when in the unfolded state. In fig. 6, the measuring tape bodies 10 are provided in a pair, and are hinged integrally. Adjacent tape bodies 10 lie in the same plane when in the extended condition, as shown in figure 7. In the present invention, the measuring tape body 10 is further provided with scale lines on the top surface or the side surface thereof to measure the length of a building. In the embodiment shown in fig. 7, a pair of measuring tape bodies 10 is used, which effectively increases the length of the measuring tape measurement.
