[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] The present application provides an electronic leveling instrument, such as Figure 1 and Figure 2As shown, an electronic leveling instrument includes: a laser receiving module, an operation button 4, a reference height locking module and a deviation determination module, the operation button 4 includes a locking button, the laser receiving module, the locking button and the deviation determination module are all connected to the reference height locking module; the laser receiving module is used to receive a laser line, and the laser line is used to indicate a reference height; the reference height locking module is used to save the height of the laser line received by the laser receiving module as a reference height when the locking button is pressed; the deviation determination module is used to output the difference between the height of the laser line received by the laser receiving module and the reference height when leveling the target surface.

[0019] The electronic leveling instrument further comprises: a laser line projector, which is used to emit the laser line. The laser line projector specifically adopts a laser horizontal line projector with a modulation function, and the frequency range of the emitted horizontal laser line is 1kHz-100kHz.

[0020] The operation buttons 4 also include an on / off button and a reset button. The reset button is used to clear the saved reference height.

[0021] The electronic leveler also includes a shell 6, the laser receiving module, the reference height locking module and the deviation determination module are located in the shell 6, a laser receiving window 5 is provided on one side of the shell 6, and the laser receiving module receives the laser line through the laser receiving window 5.

[0022] The ground of the housing 6 is the reference base.

[0023] The deviation determination module includes a display screen 3, which is used to display the difference between the height of the laser line received by the laser receiving module and the reference height in real time, and the display screen 3 is set on the surface of the housing 6. More specifically, the display screen 3 is set on the upper surface of the housing 6.

[0024] The electronic leveling instrument further comprises an X-axis leveling bubble 1 and a Y-axis leveling bubble 2, and the X-axis leveling bubble 1 and the Y-axis leveling bubble 2 are used to observe whether the electronic leveling instrument is placed horizontally.

[0025] The electronic leveler also includes a battery, which is used to supply power to the laser receiving module, the reference height locking module and the deviation determining module.

[0026] The electronic leveling instrument also includes a prompt module, which is used to issue a prompt sound when the absolute value of the difference between the height of the laser line received by the laser receiving module output by the deviation determination module and the reference height is greater than a set value.

[0027] In actual operation, the reference base is placed on a plane of reference height. When the locking button is pressed, the reference height locking module saves the laser line height received by the laser receiving module as the reference height, and the display screen 3 shows that it has been zeroed.

[0028] After the reference height locking module locks the reference height, when leveling the target surface, the electronic leveler is placed on the target surface to be leveled (the reference base is placed on the target surface to be leveled), and the deviation determination module outputs in real time the difference between the laser line height received by the laser receiving module and the reference height. At this time, the laser line height received by the laser receiving module represents the height of the target surface. If the difference between the laser line height received by the laser receiving module and the reference height is greater than 0, a positive number is displayed, and if it is less than 0, a negative number is displayed.

[0029] The present application utilizes a laser digital signal receiver to directly detect the height of the target surface, which is very intuitive during construction and can use sound and light to prompt construction workers to operate, thereby achieving high construction efficiency and saving a lot of manpower.

[0030] The electronic leveling instrument described in the present application can be applied not only to floor tile laying, but also to various other installation projects that require leveling, and can also be applied to quality inspections that require leveling.

[0031] The target surface includes the surface of floor tiles. During construction, a laser line projector with a modulation function is used to project a horizontal laser line. First, a floor tile of the reference height is determined, and then the electronic leveler is placed on the floor tile of the reference height (keeping the dual-axis level bubble level). The electronic leveler receives the modulated laser line height, and then operates the electronic leveler to memorize and lock the current height reference height. After the reference height is set, the electronic leveler can be placed on the floor tiles to be laid. The electronic leveler gives the deviation between the current construction floor tiles and the reference height based on the received laser line height, and then the electronic leveler gives a numerical prompt based on the deviation value. The construction worker adjusts the floor tile height and level according to the prompt until the current construction floor tiles reach the reference height.

[0032] Since the laser line projector can provide an overall horizontal reference surface for the entire construction site, after using the electronic leveling instrument, multiple people can work at the same site at the same time. The construction workers only need to operate according to the sound and light prompts of the electronic leveling instrument. The construction is simple, with little restriction on the technical level of the construction workers, and the construction efficiency and accuracy are high.

[0033] This application uses a modulated laser level projector in conjunction with a digital laser signal receiving sensor to read the height data of the horizontal laser line and transmit information to construction personnel in the form of a digital display screen. The electronic leveler can directly read and memorize the reference height value of the horizontal laser line under construction. Construction personnel adjust the floor tile height and levelness according to the numerical prompts displayed by the electronic leveler, so that the value displayed by the electronic leveler matches the memorized reference height value, and finally achieve the level of the overall construction surface.

[0034] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
