Abstract

The invention provides an alternating current switch device and system and a control method thereof. The alternating current switch device comprises a switch machine control part and a logic part; theswitch machine control part comprises a driving part and a representation part which are independent of each other; the driving part and the representation part can both realize data connection withthe logic part; the driving part is used for controlling a switch machine to execute a constant rotating action or a reverse rotating action on the basis of a control instruction of the logic part; and the representation part is used for collecting representation information of the switch machine and transmitting the collected representation information of the switch machine to the logic part. According to the alternating current switch device and system and the control method thereof, the switch control reliability is effectively improved, and the running safety is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of rail transit, in particular to an AC switch device, a system and a control method thereof. Background technique [0002] The computer interlocking system currently in use is a system in which the computer completes the interlocking operation, and the gravity relay circuit completes the drive and display at the drive execution layer. A large number of gravity relays are used in the system, such as figure 1 The shown AC switch control system according to the prior art includes a large number of components such as a circuit breaker RD, a phase-failure protector DBQ, and a relay DQJ, and the structure is very complicated. During manufacturing, due to the many electronic devices, the wiring is very complicated and there are many solder joints; in the actual layout, due to the complex structure, the area is large; in use, the control process and current flow are complicated; when a fault occurs, find Locating fault...
