Description

TECHNICAL FIELD

[0001] The present application relates to the turnout control technology in railway signal system, in particular to a switch machine positioning connection module for realizing the turnout fixed and reverse position indication signal, and is especially suitable for the integration of fixed and reverse position indication circuit and the error-proof connection device in DC control circuit. BACKGROUND

[0002] In the railway signal system, the switch machine is the core equipment for realizing the turnout conversion and position indication, and the accurate feedback of the turnout fixed and reverse position state is crucial for ensuring the judgment of the interlocking system and the safety of train operation. Generally, the (1, 3) row contact points in the automatic switch machine opener connect the turnout fixed position indication signal or the (2, 4) row contact points connect the turnout fixed position indication signal, which needs to be confirmed according to the actual situation on site. The wiring of the electric switch machine defaults to the automatic switch machine opener (1, 3) row contact points connecting the turnout fixed position indication signal. When the (2, 4) row contact points are needed to connect the turnout fixed position indication signal on site, two-step operations are required for switching. Specifically as shown in Figure 1 1. Cross adjustment is made to the power supply lines X1 and X2 of the switch machine in the control circuit.

[0003] 2. The connection direction of the diode in the indication circuit is changed.

[0004] Through the above two steps, the indoor turnout indication fixed and reverse position signal is ensured to be consistent with the mechanical position state of the turnout (i.e. the (1, 3) row contact points or the (2, 4) row contact points are connected).

[0005] At present, although some manufacturers have integrated the diode into a modular component, improving the wiring efficiency and maintenance convenience, these modules are mostly independent structures, only realizing the standardized installation of the diode body, without effectively associating them with the cross logic of the fixed and reverse indication circuit (i.e. step 1), lacking a unified linkage mechanism.

[0006] During the on-site construction process, when the indoor turnout fixed and reverse position signal is inconsistent with the mechanical opening fixed and reverse position of the turnout, the construction personnel need to adjust the direction of the diode in the circuit and cross operate the power supply line. Since there is no clear physical or electrical association mechanism to constrain them, it is easy to cause inconsistent configuration, leading to fixed and reverse position indication errors, and even safety hazards. In addition, due to the lack of standardized and modular overall solutions, the construction personnel need to check the drawings and test the circuit state, increasing the debugging workload, reducing the construction efficiency, and prolonging the engineering cycle.

[0007] ​Therefore, the prior art has obvious uncertainty, and it is difficult to meet the requirements of modern railway signal system on high safety, high reliability and high efficient construction. A modular structure capable of unified management and linkage configuration of the positive and negative indication line logic and the diode direction adjustment is urgently needed, so that steps 1 and 2 can be uniformly associated to improve the consistency of on-site construction, reduce human errors, and ensure the safety and stability of system operation.
