1、附 录 附录 A 外文翻译 Railroad station interconnection Using the machinery, the electrical automatic control and remote controls technology and the equipment, cause in the station scope on the semaphore, the admission passage and the admission passage rail switch have the restriction relations mutually, thi

2、s kind of relations are called the railroad station interconnection. The outline railroad station interconnection is the railway signal important component.in 1843 Britain first used the mechanical interlocking interconnection； in 1887 Japan developed successfully the interconnection box equipment；

3、in 1904 the US started to use all-electric interlocking interconnection； in 1929 the US started to use following the electricity centralized interconnection. Along with electronic accounting machines development and the popularization, some countries started to use the computer interconnection at pr

4、esent. The train enters the station the admission passage, or the outputting admission passage, is determined by rail switchs different clear position. Therefore, must have the semaphore in the admission passage entrance. Enters the station the admission passage scope which the semaphore protects is

5、 an entire station track, embarks the admission passage which the semaphore protects is should go to the sector, switches cars the semaphore is only the rail switch area. When on the admission passage rail switch clears the position to meet the admission passage requirement, the admission passage li

6、ne idle, has not arranged the identical stock roads opposite routes, the semaphore to be able to open, demonstrates the green light or the yellow light； Otherwise, the semaphore cannot open, namely demonstrates the red candle, forbids the train to enter. After the semaphore opens, on the admission p

7、assage rail switch is locked in the admission passage request position； But the opposite routes must lock up, simultaneously opposite routes semaphore is not open, demonstrates the red candle. After the train drives into the admission passage, protects this admission passage the semaphore to close i

8、mmediately, demonstrates the red candle, does not allow other trains to drive again. This kind of semaphore, the admission passage idle situation and the admission passage rail switchs interconnection relations, become guaranteed that the train and rolling stocks in station scope movement security,

9、as well as uses the station driving equipment effectively, enhances the station the traffic capacity important measure. The non-centralism interconnection rail switchs operation disperses nearby various rail switches carries on, but the semaphore may the centralized control interconnection. Divides

10、the interconnection box interconnection and the electricity locks the interconnection. Interconnection box interconnection this kind of interconnection is composed of one along with the point tongue movements switch lever and along with the semaphore wire movements signal rod. On the pole inscribes

11、the gap, through the switch lever and the signal rod mutual positions change, simulates the rail switch and semaphores different condition, realizes between the rail switch and semaphores interconnection. This kind of interconnection when the rail switch clears the position meets the admission passa

12、ge requirement, the switch lever gap position only then does not hinder the signal rod to move, the semaphore can receive the pulling force opening which the wire transmits, otherwise, the switch lever will prevent the signal rod to move, the semaphore also cannot open. Once after the semaphore open

13、s, the signal rod locates the position, In turn will prevent the switch lever to dislodge again, soon point locking in fixed position. This kind of interlocking plant is only suitable for a wire-control single track vane semaphore. Because the traverse control is away from short, is been big the tem

14、perature changes influence, needs to inspect and the adjustment artificially frequently, moreover the admission passage free time depends upon the railroad rules and regulations to come the artificial safeguard. Therefore, this kind of interconnection uses in the transportation amount being small ge

15、nerally, the stock road is short and rail switch number few non-power equipments station. The electricity locks the interconnection separately supposes the electricity on the rail switch and the signal handle to lock, the electricity locks on has the contact separately on behalf of the rail switch a

16、nd the signal position. Locks the contact through side rail switch electricity to control opposite party signal electromagnetism to lock the electric circuit which the electricity locks, realizes the semaphore interconnection between the semaphore and the rail switch as well as. The electricity lock

17、s has a magnet coil, the armature and locks up the piece to be able to upper shift along with the go-between revolves, otherwise locks up the piece impediment go-between to upper shift, namely forbids to move the handle, the rail switch or the semaphore is locked in the position. The electricity loc

18、ks other is loaded with along with locks up piece revolving, but the make and break electric contact group, closed either the separation reflects the rail switch or semaphores actual condition through this contact, namely simulation controlled plant condition. Thus, locks through the rail switch ele

19、ctricity the contact locks for the signal electricity the magnet coil delivers the electric current, only then the switch location correct only then causes the closed circuit, the signal electricity to lock has the enough electric current, after namely the approval moves the signal handle to cause t

20、he semaphore opens, by the signal electricity locks the contact for the rail switch electricity to lock the magnet coil power transmission electric circuit to separate, therefore cannot move the rail switch handle again ,soon the rail switch locks in the position. Obviously, uses electricity between

21、 the rail switch handle and the signal handle locks the relation to obtain the interconnection relations, also not both distance limit far and near, also not rail switch number how many influence. When use light signal, the control is away from is not limited. The electricity locks the interconnecti

22、on to obtain the promoted use in China non-power equipments station. The centralized interconnection rail switch concentrates in the station signal tower inside control, common has the mechanical interlocking interconnection, all-electric interlocking interconnection and so on. The mechanical interl

23、ocking interconnection rail switch and semaphores operation handle concentrates in the signal tower, these operation handle company has the mechanical member, between the member implements the interconnection with the lock. The mechanical interlocking interconnection does not need the railroad switc

24、h operator to switch in the scene, thus raises the work efficiency, and may prevent, because the station personnels wrong creates with railroad switch operator between relation auto accident. But, because wire and drive pipes transmission range of movement after the stress will haunch up or pulls stretches will cause the losses, thus the control distance will be restricted. In addition, the mechanical member and the lock wear, will reduce the interconnection the security, therefore mechanical interlocking interconnection in the 1950s later gradually by all-electric interlocking
