[0002] Laser ranging uses a laser as a light source for ranging. When a laser rangefinder works, it emits a very thin laser beam towards the target. The laser beam reflected by the target is received by a photoelectric element, and a timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target.

[0003] After retrieval, a Chinese utility model patent with the patent application number CN202120000675.1 discloses an intelligent laser line projection and ranging level, including: a long strip-shaped outer shell, a screen cover and a button cover attached to the side surface of the outer shell, a long strip-shaped inner shell sleeved inside the outer shell, and a cover covering one end of the outer shell and fixing the inner shell; a circuit board, a screen, buttons, a charging interface, a laser line projection module, a laser ranging module, and a battery installed inside the inner shell; the buttons and the charging interface are both installed on the circuit board, the laser line projection module is located at one end of the inner shell and the emission direction is outward from the end surface of the outer shell, the laser ranging module is located at the other end of the inner shell and the emission direction is outward from the end surface of the outer shell; an angle sensor, a main control chip and peripheral circuits are arranged on the circuit board. This intelligent laser line projection and ranging level can accurately project a reference line at the required angle, can also accurately measure the distance between the intelligent laser line projection and ranging level and the object to be measured, and can also accurately detect the levelness of the surface of the object to be measured.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0026] Such as Figures 1-5As shown, the spirit level with a built-in distance measurement and layout function includes a housing 1. Inside the housing 1, there is a spirit level pendulum body 2. On the housing 1, there are a movement module 3, control buttons 4, a display screen 5, and a circuit control board 6. The circuit control board 6 is electrically connected to the movement module 3, control buttons 4, and display screen 5 respectively. On the movement module 3, there are a main control circuit and a laser drive circuit. On the circuit control board 6, there are a button circuit, a display drive circuit, and a buzzer circuit. The laser drive circuit, button circuit, display drive circuit, and buzzer circuit are all electrically connected to the main control circuit. It can be understood that the movement module 3 converts the optical signal into an electrical signal and transmits it to the laser drive circuit. The laser drive circuit calculates the distance between the target and the observer based on the time difference between the emitted laser line and the received laser line. The main control circuit then sends this distance measurement information to the circuit control board 6. The circuit control board 6 transmits this distance measurement information to the display screen 5 through the display drive circuit. At the same time, the main control circuit compares this distance measurement information with the set distance input by the user through the control buttons 4. When the two distances are the same, it sends a control signal to control the buzzer circuit to emit a sound to prompt the user.

[0027] Specifically, several conical laser tube protection cases 7 are arranged on the outer side of the housing 1. A base 8 is arranged at the bottom of the housing 1.

Distance measurement positioning planes 18 are arranged on the outer surfaces of the first conical laser tube protection case 16 and the second conical laser tube protection case 17. It can be understood that by setting the rotating shaft 14 and the rotating shaft installation groove 15 to cooperate and rotate with each other, the movement housing 12 and the movement module 3 can rotate 90 degrees, so as to control the distance from the distance measurement positioning plane 18 on the conical laser tube protection case 7 to the wall. When measuring the distance, the spatial positioning method can be used to better position the placement position of the spirit level.

[0029] Specifically, an amplification circuit, a clock circuit, a bias boost circuit, an LDO power supply circuit, and an FPC interface J2 are further provided on the movement module 3. The amplification circuit, the clock circuit, the bias boost circuit, the LDO power supply circuit, and the FPC interface J2 are all electrically connected to the main control circuit. An FPC interface J3 and a power management circuit are further provided on the circuit control board.

The single-chip microcomputer chip U1 can be an STM32030C8 chip, etc., and the analog switch chip U3 can be an SGM3157 chip, etc.

[0030] It can be understood that the amplification circuit includes an inductor L4, a triode Q3, a capacitor C34, a diode D4, a resistor R25, a resistor R8, a resistor R32, and several operational amplifiers, etc. The clock circuit includes a clock chip U11, a crystal oscillator Y1, a capacitor C11, and a capacitor C37, etc. The clock chip U11 uses a Si5351 chip and is used to generate multiple high-precision clock signals through frequency division, frequency multiplication, or synthesis methods. The bias boost circuit includes a resistor R14, an inductor L1, a transistor Q10, a diode D1, and a resistor R18, etc., which are connected in sequence. The transistor Q10 is connected to the single-chip microcomputer chip U1. The LDO power supply circuit includes a voltage conversion chip U4, a capacitor C6, a capacitor C12, and a capacitor C20. The voltage conversion chip U4 uses an LM2985-3.3 chip and outputs a 3.3V power supply to supply power to the single-chip microcomputer chip U1. The buzzer circuit includes a resistor R33, a buzzer B1, a triode Q11, and a resistor R31, which are connected in sequence.

It can be understood that the movement module 3 functions as a distance measurement, used to detect the distance from the level to the wall. The control button 4 is used to provide the user input to set the measurement distance. The display screen 5 is used to provide a display interface and display corresponding measurement data, etc. The buzzer circuit is used to emit a prompt sound to prompt the user that the current distance is the set distance.

[0031] It can be understood that the design of the present invention is reasonable and the structure is unique. It solves the pain point that the traditional level is difficult to control the distance from the wall during use, can realize the continuous measurement function, display the distance to the wall, and can set the desired distance. By emitting a beeping sound and displaying a prompt on the screen to confirm whether the set distance is reached, the function of setting the distance is added. When the set distance is detected, a prompt is given, thus meeting the user's usage requirements.
