Problems solved by technology
[0007] The present invention aims to solve the problem that the devices selected in the existing circuit for controlling the switch machine are easily broken down. Since the power supply is uncontrollable, the device may cause fatal danger after the device breaks down, and the circuit safety is not guaranteed.
[0008] On the other hand, the present invention solves the problem that the existing devices need to be replaced once they break down, the maintenance cost is too high, the traffic operation of the track line is affected, and the interlocking system for controlling the switch machine needs to be connected to the track through a long cable. The control of the switch machine next to it is easy to affect the control of the switch machine due to the fault of the cable

The embodiment of the invention disclose a control system of a direct-current point machine and a control method thereof. In the control system, an interlocking execution layer comprises a rectifier for converting alternating current into direct current; the interlocking execution layer is connected to an alternating-current power source; and the alternating current is converted into the direct current through the rectifier and then input to the direct-current point machine. In the control system, the alternating-current power source can not drive the direct-current point machine; therefore, even if devices between the alternating-current power source and the direct-current point machine fail resulting in mis-connection between the alternating-current power source and the direct-current point machine, the danger caused by abnormal operation of the direct-current point machine due to the uncontrollable power source can be avoided so as to ensure the safety of a circuit.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of switch machine control, in particular to a DC switch machine control system and control method. Background technique [0002] The electric switch machine is an electrical device used to control the rotation of the switch and detect the position of the switch. According to the driving power supply, it is divided into two types: DC electric switch machine and AC electric switch machine. At present, the commonly used DC switch machines mainly include ZD-6 DC electric switch machines, which adopt a four-wire interface. The four wires include a special line for rotation, a special line for indication, and a line for positioning, rotation and positioning. , a reverse rotation and reverse representation line. Its rated driving voltage is 160V DC and its current is 2A. [0003] In the all-electronic computer interlocking, or the electronic execution layer design of computer electronics...
