Mt386-1995 test methods and determination rules for fire retardancy of fire retardant cables used in coal mines and Q/TX 001-2006 plastic insulation control cables used in coal mines.
Dense places; In places with high safety requirements for dense cables or closed channels, automatic fire detection and alarm devices suitable for reliable operation of the environment should be equipped. The oil supply system of open oil charging cable should be equipped with automatic fire alarm and lock device which can reflect the state of oil spraying. Places with high safety requirements, such as dense cable parts of underground public facilities, terminal setting of multi-return oil-filled cables and other places, can be equipped with special fire fighting facilities such as water spray extinguishing.

用于平巷、斜巷及机电硐室做通信线以及用于平巷，竖井或斜井作主信号传输。
Busy表示功能块执行情况的输出，如果为高电平，表示功能块正在执行。
我们读取它的下降沿，来触发下一次操作。
Error是功能块的错误，可能你会有疑问，为什么通信错误不用这个信号呢？其实这个错误表示的范围更广,它表示功能块检测到错误就报警，有时候，我们通信正常，当我们读取的数据有问题，或是参数设置不正确时，也会报错，而我在程序中的错误仅仅是通信不上的错误，也就是，这个Error表示的范围更广泛，它更适合我们调试的时候监控。

Non-combustible mineral insulated cables may be used in oil tank areas, public buildings with important wooden structures, high temperature places, and other situations where fire resistance requirements are high and installation is acceptable and economic performance is acceptable. When the self-capacity oil filled cable is applied to the public corridor, passenger tunnel, bridge and other situations requiring fire prevention treatment, it can be buried in sand. Close to the cable trench of high voltage current, voltage transformer and other oil-bearing equipment, it is advisable to seal the trench cover plate in this section.
