Problems solved by technology
[0003] 1. There is basically no pedestrian locking function in the fully mechanized mining face. A small number of pedestrian locking devices with a high degree of automation use infrared pyroelectric sensors. The surface is easily affected by coal ash, the reliability is not high, and it is also vulnerable to temperature influence, cause malfunction
[0004] 2. There is basically no straightening function in the fully mechanized mining face. In most mines, the hydraulic support is manually controlled and straightened through the support controller. The length of a working face is about 200 meters, and the manual straightening efficiency is low. Straight effect is not good
[0005] 3. Some fully mechanized mining faces use inertial navigation for straightening, but the cost is too high. The installation and use cost of a working face is 30 million yuan
Its effect can not meet the straightening requirements in terms of actual working conditions

The invention relates to the technical field of electronics, communication and automation, in particular to a material level inclination angle sensor which comprises a shell, a quick plug-in connector, an ultrasonic module, an inclination angle module and a main control module. The quick plug-in connector is arranged on the shell; the main control board is provided with a power interface and a communication interface which are respectively connected with the connector on the shell; two groups of ultrasonic modules are mounted on the inner side of the shell cover plate and communicate with themain control module through serial ports; and a group of inclination angle modules are arranged in the shell and are communicated with the main control module through an RS485 bus. The material levelinclination angle sensor is provided with a support action personnel lock. Life safety of support workers and coal machine drivers can be improved, the sensors are installed on a top beam and a base of the hydraulic support, the angle state between the hydraulic support and the connected hydraulic support and distance information between the hydraulic support and the scraper machine can be detected at the same time, and the hydraulic support straightening device can be used for straightening the working face hydraulic support.
Description
technical field [0001] The invention relates to the technical fields of electronics, communication and automation, in particular to a material level inclination sensor. Background technique [0002] The material level inclination sensor is mainly used in the fully mechanized mining face of the coal mine. It is installed on the hydraulic support and needs to output corresponding data information with the movement of the equipment. Carry out locking protection. At present, the pedestrian locking and straightening of the fully mechanized mining face have the following deficiencies: [0003] 1. There is basically no pedestrian locking function in the fully mechanized mining face. A small number of pedestrian locking devices with a high degree of automation use infrared pyroelectric sensors. The surface is easily affected by coal ash, the reliability is not high, and it is also vulnerable to temperature influence and cause malfunction. [0004] 2. There is basically no straigh...
