Abstract

The invention relates to the technical field of electronics, and particularly relates to a non-contact liquid level monitoring and alarming device based on laser ranging. The non-contact liquid level monitoring and alarming device comprises a laser range finder 1, a processing unit 2 and a processing unit 3, wherein the laser range finder 1 comprises a laser transmitting module 11 and a laser receiving module 12. The non-contact liquid level monitoring and alarming device based on laser ranging is characterized by comprising a support frame 4 used for arranging the laser range finder 1, wherein the support frame 4 comprises a base 41 used for fixing, a vertical rod 42 the lower end of which is connected with the base 41, and a cross rod 43, the upper end of the vertical rod 42 is fixed through screws, the cross rod 43 is provided with the downward laser range finder 1, and the vertical rod is sleeved with a buoy 44 capable of sliding freely up and down. The liquid level above a waterline is monitored and early warned, the non-contact liquid level monitoring and alarming device and a device for establishing an alarm system through a single chip microcomputer and an integrated circuit can be realized, and the real-time monitoring and alarming of mortar water level on a new building material production line and other operation field can be met.

Description

technical field [0001] The invention relates to a distance measuring device for obtaining a target distance by using a laser measuring module, in particular to a non-contact liquid level monitoring and alarming device based on laser distance measuring. Background technique [0002] Some traditional distance measurement methods have insurmountable defects in some special occasions. For example, liquid level measurement is a kind of distance measurement. The traditional electrode method uses a differential distribution electrode to detect the liquid level by feeding electricity or pulses. The electrode is soaked in water or other liquids for a long time, and it is easily corroded and electrolyzed. Loss of sensitivity. These problems can be solved by using ultrasonic distance measurement, so ultrasonic distance measurement technology has been widely used in the fields of industrial control, survey measurement, robot positioning and safety precautions. The so-called ultrasonic...
