板石矿业公司上青矿副井井筒共有s个提升中段,每个中段部没有2 m 提升机、3 m 提升机及2个信号室。每个信号室和2部提升机操作室均设有1部青岛四方机车有限公司生产的磁石电话机,用于井筒信号室和提升机操作室之间的通信,以确认和联系罐笼的运行。整个磁石电话机通信系统的电话机都并联在一个回路中,一方按下呼叫键,其他通讯线路连接方都可以接听,只有通过对话才可能与想找到的对象沟通,这种通讯方式既浪费非接活人员的工作时间.同时大家同时接听电话,杂音大.影响通话质量,易受干扰,严重的话还会造成事故。磁石电话机只有按出键和接受键,属于一对一型通信设备,不适合井下多个部门之间准确的联系和通讯。为此,针对磁石电话机通信系统的缺点,决定采用新型的通讯设备来取代它,以保证井筒通信的可靠性。
There are a total of s ascending sections in the shaft of the secondary shaft of the Shangqing Mine of the Slate Mining Company. There is no 2-m hoist, 3-m hoist and two signal rooms in each middle section. Each signal room and two hoist operating room are equipped with a magnet telephone set produced by Qingdao Sifang Locomotive Co., Ltd. for communication between the well bore signal room and the elevator operating room to confirm and contact the operation of the cage. The entire magnet telephone communication system telephone are connected in parallel in a loop, one press the call button, the other communication line connection party can answer, and only through the dialogue may want to find the object to communicate, this communication is a waste of non- Then live the working hours of the staff.At the same time we answer the phone at the same time, loud noise.Affect the call quality, susceptible to interference, serious cases can also cause accidents. Only by pressing the magnet key phone and accept the key, belonging to one-type communications equipment, not suitable for accurate contact and communication between multiple departments downhole. For this reason, in view of the shortcomings of the magnet telephone communication system, it is decided to replace it with a new type of communication equipment so as to ensure the reliability of wellbore communication.
