Downhole equipment detection rule set reduction method based on discrete Calman filter

Abstract

The invention discloses a downhole equipment detection rule set reduction method based on discrete Calman filter and belongs to coal mine equipment detection methods. The reduction method of safety rule sets includes establishing geographical position coordinates for an entire coal mine; configuring safety GPS locating equipment to a detecting staff, and determining the current state, including the position and speed, of the detecting staff; then on the basis of the current state, predicting the state in the next moment by the discrete Calman filtering algorithm, and selecting a roadway to be selected. A handheld terminal is free of downloading all safety rule sets of all downhole equipment, only the current rule sets are downloaded; reduction can be performed by the discrete Calman filtering theory, the detecting staff arrives at a roadway 1, the handheld terminal downloads a safety rule set 1, next equipment to be detected is predicted according to the discrete Calman filtering theory, the safety rule sets relative to the equipment is pre-downloaded to the handheld terminal, and the detecting efficiency is improved greatly.

Description

technical field [0001] The invention relates to a coal mine underground equipment detection method, in particular to a method for reducing the underground equipment detection rule set based on discrete Kalman filtering. Background technique [0002] Nowadays, when technicians hold handheld devices in the mine to detect the equipment installed in the mine, they need to download all the rule sets in advance. When the device is detected, the running status of the device is detected by comparing the data in the rule set. But now the rule set is stored in the form of a database, and it is not reduced on the handheld terminal, and all the downloaded ones are stored in the device. This will put a lot of pressure on the search data set of the handheld terminal, and the search rule set of the handheld terminal will be very slow, slowing down the efficiency of security detection.
