Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] refer to Figure 1-6 , a kind of inquiry method that mine belt protection system locks along the line described in the specific embodiment, comprises a query host, a plurality of locking modules along the line and a terminal module, and the steps of the inquiry method are as follows:

[0027] 1) The query host sends a voltage query signal with a certain pulse width through the query line;

[0028] 2) The blocking modules along the line receive and identify the voltage query signal in the above step 1);

[0029] 3) The blocking module along the line replies the voltage signal of a certain pulse width to the query host through the query line according to the state of the peripheral circuit. state and record, and then send the query signal to query the next blocking module again until the terminal module is queried;

[0030] 4) After receiving the...

Abstract

The invention relates to a mine belt protective system along-line shutting query method. The mine belt protective system along-line shutting query method comprises a query host, a plurality of along-line shutting modules and a terminal module. The query method includes the steps that the query host sends a query signal, the along-line shutting modules and the terminal module process the query signal and replies the query signal, and the query host then processes the replied signal to achieve remote fault location, remote input and remote control. The mine belt protective system along-line shutting query method has the beneficial effects that remote fault location and along-line shutting can be achieved without address coding for along-line shutting, and replacement without influencing positioning positions can be achieved; and the structure is simple, operation is convenient, normal communication can be carried out by sequentially connecting equipment with cables, debugging and allocation are not needed, installation debugging and allocation are greatly simplified, the fault rate is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mine collection systems, in particular to a query method for locking along a mine belt protection system. Background technique [0002] The operation in the mine is intricate, and the probability of safety accidents is also high, so mine safety is the top priority in the production process; the mining belt is an important transmission equipment for transporting mineral materials, so whether the working condition of the mining belt is in good condition has a great impact on safety. Production is very important. [0003] At present, most of the communication of a single master device controlling multiple heavy devices is based on the master device searching for heavy devices and then configuring settings. The on-site use and debugging are complex and cumbersome, not only the detection position accuracy is low, but also takes a long time, affecting work efficiency. Contents of the invention [0004] The ...
