The art

2、icle first gives an explanation of the basic theory of mine rail transportation and external devices, and then describes the process of historical development, composition and function of the monitoring system of mine rail transportation.The system is a network system made of PC,PLC ,Ethernet switch

3、es switch machines, signals and a variety of sensors via RS-232 / RS-485 .The article highlights the PLC hardware and software design and configuration design. This system both has the advantages of the PLC in the rail transportation system and outstanding features of Ethernet in long-distance trans

4、mission , it has stable features, reliable data transmission, low-cost equipment, flexible system expansion, and can be applied to a variety of large, medium and small coal mines rail transport monitoring.2 Basic knowledge of the rail transportVoyage, route, interval is a fundamental part of the mon

5、itoring system.this three elements form a monitoring system. Training to perform a transport task, traveling from the starting to the end of the journey is called a flight. Flight is determined by the transportation task. The number of the voyage is the same with the number of transportation tasks.

6、The voyage is the composition of the moni-toring system, its necessary to be sure to all the voyage in the design of monitoring system is included, not missing, otherwise the system is incomplete and unable to complete all the scheduled jobs. Reasonable dispatch for running on the motor vehicle can

7、improve the ability to run. A certain voyage is divided into a number of approach. A voyage is end to end, there is signal protection on each voyage approaching to the entrance. The approach is shown by the turnout position and signal state decision. We say that opening into the road then pull into

8、the turnout on the road approach the desired position, then opening up the signal of the protection in this approach. If the switch position is wrong, signals are not allowed to open; Once the signal is open, you are not allowed to switch to change position, until the signal is turned off, the train

9、 all through the turnout so far. The design of monitoring systems, range is determined by transport systems and trans-port tasks, while the approach should designers division, division rational approach, not only reasonable scheduling vehicles, and can increase the transport capacity. Divided into i

10、ntervals bring certain benefits to rail transport, but the interval increases, the control circuit is also a corresponding increase, therefore, whether the division of the interval and divided into several intervals, each approach should be divided to go through a detailed comparison can be determin

11、ed, not necessarily interval. The interval of each into the road is not more than three. Hostile voyage is most likely to occur two trains relative traveling on the same track two driving routes. The two trains traveling relatively close to each other atresia are not driving, is called deadlock. Bet

12、ween different voyage into the road, there is often a relationship of mutual restraint, known as the chain. The two approaches can not open or crash occurs, and this mutual res-traint approach is called a hostile approach. Detection of hostile approach is the basis of the motor vehicle semi-automate

13、d schedul-ing. Motor vehicle from a starting point to the end of the voyage, including a number of approach roads. Before the motor vehicle a route into another route, the computer will detect its hostile approach trains occupy, if the test results of open conditions, the green light motor vehicles

14、to enter the next approach. Train all through the route, lights automatically under computer control to change to red.目前,对于我国绝大多数矿井，轨道运输仍是井下大巷的主要运输手段，我国现有煤矿轨道近万千米，由于井下工作条件差、行车密度大、光线弱等原因，致使机车运输通过能力差且事For the vast majority of our mine, rail transport is still the main means of transport of the undergr

15、ound roadway, our existing coal mine track ten thousand kilometers underground working conditions, traffic density, weak light and other reasons, resulting in the motorcycle transport through capacity poor and frequent accidents. 矿井轨道运输的这种状况,将直接影响到煤炭的生产情况。 This situation of mine rail transport-tatio

16、n, will directly affect the production of coal. 提高轨道运输的能力,一是加强管理,其次就是采用现代化的技术和设备,其中采用矿井轨道运输监控系统是行之有效的举措。 Improve the ability of rail transport, the enhancement of management, followed by the use of modern technology and equipment, which mine rail transport monitoring system is effective initiatives. 煤矿采用轨道运输监控系统以后 , 可以显著提高矿井的生产效率 , 满足煤矿生产需求 , 并且可以更好地做到机车安全调度 , 减少运输事故的Coal using the rail transport monitoring system can significantly i
