Description
Technical Field
The invention belongs to the technical field of sensor layout for mines, and particularly relates to a sensor layout system for a mine and a control method thereof.
Background
Mineral resources in China are rich, and along with the development of science and technology, a large number of various sensors are installed in both strip mines and underground mines. Most mines in China have been exploited for a long time, and detection equipment such as sensors and the like are often added with new lines in the existing circuit transmission pipelines. And this faces new problems: firstly, the number of sensors required to be arranged in mine construction is large, and the existing parallel single-channel sensor distribution mode can seriously occupy the space of a circuit pipeline, so that the space of the circuit pipeline is insufficient, or the number of the sensors is required to be reduced; secondly, the number of signal transmission cables can be greatly increased by using a parallel single-channel distribution mode for a plurality of sensors, and the cost is huge; thirdly, the arrangement mode of the parallel single-channel sensors can only arrange a limited number of sensors during each construction, and a large number of sensors are arranged simultaneously, so that a large amount of manpower is needed, and the labor cost is increased. Therefore, it is desirable to consider using a tandem sensor arrangement that differs from the existing parallel single channel sensor arrangement.
The distribution mode of the series-connected electric appliances is mostly applied to the situations that the area of a space region is small, the series-connected electric appliances do not work simultaneously and the like, and the series-connected electric appliances are rarely used under the condition of a large-scale construction region. The main reasons for this are: firstly, after a certain position in the series circuit is disconnected due to faults, all the subsequent electrical appliances are disconnected; secondly, due to the voltage and signal transmission requirements, the series-connected electric appliances cannot work normally at the same time.
Therefore, a sensor layout system for mine and a control method thereof are needed to solve the above technical problems.
