Embodiment Construction

[0029] The specific embodiments of the present invention will be briefly described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those skilled in the art without creative work Examples, all belong to the protection scope of the present invention.

[0030] Figure 1-Figure 3 The preferred embodiment of the present invention is shown, and it is analyzed in detail from different angles.

[0031] Such as figure 1 , 2 A method for measuring the footage of a boring machine is shown, comprising the following steps:

[0032] Step 1, install the reflective target 1 and the distance measuring device 2. The reflective target 1 is installed above the track 3 of the second transport belt conveyor 4, relatively stationary with the track 3. The distance measuring device 2 is inst...

Abstract

The invention discloses a method for measuring the footage of a roadheader, which relates to the technical field of footage measurement. In this measurement method, by setting the distance measuring device and the reflective target, the laser sensor is used to emit a laser beam to the reflective target, and the laser beam reflected by the reflective target is received, and the time from the emission to the reception of the laser beam is measured according to the timer, so as to calculate from The distance L from the laser sensor to the reflective target automatically measures the advance of the roadheader; at the same time, it monitors the amount of returned light C, and determines whether the laser beam hits the target according to the amount of returned light, and starts the target-seeking process in due course. A method for measuring the length of a roadheader disclosed by the invention, by setting a distance measuring device and a reflective target, automatically measures the length of the roadheader, and replaces manual measurement with automatic measurement, which has high measurement accuracy and reduces labor intensity; at the same time, it can be measured by laser The amount of light returned by the sensor is used to determine whether the laser beam hits the target, so as to start the steering gear pan / tilt according to the requirements, and carry out the target-finding work, further improving the accuracy and integrity of the distance measurement.

Description

technical field [0001] The invention relates to the technical field of footage measurement, in particular to a method for measuring the footage of a roadheader based on fusion of a laser sensor and an attitude sensor. Background technique [0002] The excavation footage is the length of the tunnel that is excavated when various shaft chambers are excavated. It is an economic and technical indicator in production statistics. The ratio of production excavation footage to mine output reflects the degree of cooperation between production excavation footage and mining. [0003] The working conditions of the excavation face are complex and changeable. At present, manual measurement is mainly used to calculate the excavation footage. On the one hand, there are problems such as large measurement delay and mixed invalid footage; It is labor-intensive to record underground and measure the excavation footage. [0004] Therefore, in view of the above problems, it is necessary to propos...
