Background technique

In recent years, the real estate industry has developed rapidly, and now countless high-rise buildings are completed almost every day. But when the main frame of the building is built, when the workers want to enter the main frame for the next step of improvement work, it is a troublesome problem to judge which floor the workers are on. In most cases, the workers can only silently remember which floor they are on when they go upstairs. However, due to the noisy environment of the construction site, workers often forget the number of floors, resulting in the problem of repairing the wrong floor. Therefore, it is urgent to design a simple and easy-to-use altimeter.

As a further improvement, a plurality of anti-slip grooves are provided on both sides of the housing, and the width of the anti-slip grooves is suitable for an adult's fingers.

As a further improvement, a solar cell panel for charging the battery is provided on the back of the casing, and the solar cell panel is electrically connected to the control circuit board.

The beneficial effects of the utility model are as follows: firstly press the two-way measurement button to switch to the two-way measurement mode, the user holds the housing with its upper and lower ends aligned with the top surface and the ground of the floor, and the laser emitters at the upper and lower ends of the housing emit light. The laser receives the reflected laser light through the laser receiver, and feeds back the signal to the control circuit board. The control circuit board calculates the floor height according to the time difference; then press the one-way measurement button to switch to the one-way measurement mode. Go out of the building and align the lower end with the ground, the laser emitter at the lower end of the housing emits laser light, receives the reflected laser light through the laser receiver, and feeds back the signal to the control circuit board, and the control circuit board calculates the floor space of the user based on the time difference. Height from the ground, the control circuit board is equipped with a calculation module to calculate the floor height and the height from the ground to calculate the number of floors and display it on the display screen, which is convenient for the user to directly observe and understand the floor. The utility model has the advantages of compact structure, easy portability, simple and fast operation, and the self-contained battery can stand by for a long time, and is suitable for construction sites.
