Problems solved by technology
The hollowing of the ground causes the following problems: the place where the floor tiles are laid, because the ground is empty, the ground needs to be stepped on frequently, and the floor tiles will fall off after a long time
When decorating a house, it is necessary to lay floor tiles or floors. The decoration effect is not only determined by the quality of the floor tiles and the floor itself, but also affected by the quality of the floor tiles and the floor. big economic loss
[0003] At present, the traditional detection method for hollowing is almost entirely done manually, relying on the sound of a small hammer hitting the ground or floor tiles, or the floor to determine whether there is hollowing, and only professional construction personnel or house inspectors can make accurate measurements determination

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 and figure 2 As shown, the present invention provides a method for detecting ground hollows based on radar. First, the smart car is turned on, and the operator sends a driving signal to the smart car through the remote control. The smart car turns on the radar and sends electromagnetic waves to the ground and walks in the room; The radar waveform when there is no hollow drum is preset in the control center of the car, and compared with the returned waveform received by the radar electromagnetic wave receiver to judge the hollow drum area; the control marking unit in the smart car marks the hollow drum area; After the marking is completed, the smart car will sound an alarm.
[0024] When the smart car encounters an empty drum, it will mark the empty drum area and stop moving forward, and conduct a small-scale...

The invention provides a method for detecting ground hollows based on radar. The smart car is turned on, and the smart car turns on the radar to send electromagnetic waves to the ground and walks in the room; the waveform returned by the radar is compared with the standard waveform to judge the hollow area; the smart car controls The marking unit marks the hollow area; after the detection is completed and the marking is completed, the smart car will sound an alarm. The present invention also provides a device for detecting ground hollows based on radar, including a smart car, a radar detection module, and a marking unit. Drum area to be marked. The present invention can automatically detect the ground condition of the vacant room and the tile and floor paving effect by the trolley when the house is inspected after the project is completed, or after the floor tiles and the floor are laid. At the same time, one person can control multiple trolleys at the same time, which can save To save a lot of manpower and material resources, improve the detection speed and accuracy.
Description
technical field [0001] The invention relates to the automatic detection of floor tiles and floor hollows when a house inspector is inspecting a house or during a decoration process, in particular to a device and method for detecting ground hollows based on radar. Background technique [0002] The hollowing is caused by the air in the original masonry and the powder ash layer. The "hollowing" in the quality of the house generally refers to the floor, wall, ceiling decoration layer (plastering or pasting bricks) and structural layer (concrete) of the house. or brick wall) due to the sticking, the hollowing phenomenon that occurs due to the weak combination, commonly known as "two-layer skin". The hollowing of the ground causes the following problems: the place where the floor tiles are laid, because the ground is empty, the ground needs to be stepped on frequently, and the floor tiles will fall off after a long time. The floor should have wooden keels, and the hollow side is ...
