Embodiment Construction

[0018] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0019] Fig. 1 shows the block diagram of the embodiment of this electronic level. The electronic level is composed of an acceleration sensor 1, a microprocessor 2, an LCD display driver 3, an LCD display 4, a voltage stabilizing circuit 5, and keys 6.

[0020] The acceleration sensor 1 is used to collect the acceleration signal and send it to the microprocessor 2 in the form of analog voltage signal for data decoding and processing. The acceleration sensor can be SCA60C or other.

[0021] The microprocessor 2 is used for performing AD conversion on the analog signal of the acceleration sensor 1, correcting and decoding the data, changing the signal into an angle value with the horizontal plane, sending it to the LCD display driver 3, and displaying the value. Choose HT46R52 or others.

[0022] The voltage stabilizing circuit 5 is used to provid...

Abstract

The invention provides an electronic level gauge and calibrating and using method thereof. The electronic level gauge comprises a cuboid casing, and an acceleration transducer, a main circuit board and a LED display driver are arranged in the cuboid, the circuit includes that a microprocessor and a voltage regulator circuit are arranged on the main circuit board, the acceleration transducer is connected with the microprocessor, the microprocessor is connected with the LED display driver and keys, the LED display driver is connected with a LED display, the voltage regulator circuit provides working power source for the acceleration transducer, the microprocessor and the LED display driver. The calibrating method employs twice horizontal calibrations and twice perpendicular calibrations. The using method is respectively positioning the high end and the low end of the level gauge in the high position and low position of measured surface. The electronic level gauge has the advantages of simple overall structure, low cost, easy manufacturing products and the like, which can meet various requirements of horizontal and angle of inclination measuring in large or precise projects, and has wide application prospect.

Description

technical field [0001] The invention belongs to the category of measurement, and in particular relates to a level, an inclinometer and calibration and use methods thereof. Background technique [0002] The spirit level is a measuring instrument for measuring the level, which is widely used in large-scale or precision engineering such as buildings and bridges. At present, water bubble sensors are commonly used in level instruments. The inclination is determined by measuring the position of water bubbles, and its accuracy is low; angle. [0003] In a word, in the above-mentioned existing electronic level, there are problems such as complex structure and low precision of the level, which cannot be used for precise measurement, let alone measure angles within -5 to 95 degrees. Contents of the invention [0004] The object of the present invention is to provide an electronic level and its calibration and use method, which can solve the above problems and meet the needs of sim...
