Embodiment Construction

[0028] A method for statistics of shearer propulsion, comprising the steps of:

[0029] S1. Collect the infrared shearer trajectory signal data (time-frame) and the encoder shearer trajectory signal data (time-meter) of the electro-hydraulic control face, and calibrate the two data to repair the shearer trajectory;

[0030] from figure 1 It can be seen that due to the current infrared sensor and shaft encoder of the coal mining machine are affected by the harsh environment of the mine, abnormal problems are prone to occur, and the coal mining machine trajectory curve generated only by the "encoder" or "infrared signal positioning" is easy Missing, jumping and other phenomena occur. In order to display the shearer trajectory information more realistically and realize the integrity, continuity and reliability of the shearer trajectory, the infrared sensor on the bracket and the shearer shaft encoder are used to calibrate each other to obtain the correct Hydraulic support number...

Abstract

The present invention relates to a method for statistics of the advance degree of a shearer, which comprises the following steps: S1 confirms the track of the shearer within a monitoring period, confirms the cutting point of the cycle according to the track of the shearer, and obtains a cutting point by counting the number of cutting points of the cycle The shearer feed quantity in the monitoring period; the shearer trajectory is the time series trajectory of the shearer position information; S2 calculates the advance degree of the shearer according to the shearer feed quantity and the shearer knife footage , Propulsion = Shearer knife feed quantity * Shearer knife feed footage. Compared with the traditional scheme, this scheme has greatly improved the monitoring efficiency and accuracy of the shearer's propulsion degree.

Description

technical field [0001] The invention relates to a statistical method for the propulsion degree of a coal shearer, which belongs to the technical field of coal mining. Background technique [0002] Pushing degree refers to the advancing distance of the working face during the production process. The calculation of the advancing degree of the working face is an important part of the daily production activities of the coal mine. Through the calculation of the advancing degree of the working face, the coal production can be calculated, the production efficiency can be assessed, and the advancing speed can be evaluated. At the same time, it can be correlated with the law of mine pressure , to calculate the initial and periodic pressure steps of the top plate. However, the current calculation of propulsion is mainly done by manual on-site statistics, including nose propulsion and tail propulsion. Each piece of data is reported layer by layer, and manually copied and archived. The...
