Problems solved by technology

[0002] In the traditional signal system, the turnout switch machine is centrally controlled by the signal system. In the maintenance process of the turnout, it is necessary for the dispatcher to block the relevant turnout on the operation interface. After the dispatcher and the maintenance personnel complete the confirmation procedures, the maintenance Personnel carry out maintenance activities on the turnout on site. During the turnout maintenance operation, the operation of the turnout order requires the dispatcher to participate again, so that the maintenance operation process of the turnout is overly dependent on the normal work of the on-site maintenance personnel, the central dispatcher and the signal equipment. As a result, the efficiency of turnout maintenance operations is low; in addition, in the overhaul project of the signal system, it is necessary to complete the debugging task of the signal system and under the precondition of normal operation of the signal system, the consistency calibration of the switch machines in the entire station can be carried out. As the relationship between the two work tasks is tightly coupled, it is not conducive to the optimization of signal engineering project management

specific Embodiment

[0054] figure 1 with figure 2 These are examples of control panels. In order to ensure that the safety confirmation and turnout maintenance work is performed separately by personnel with different roles, it is necessary to determine that the control mode switching is completed under different interfaces, and the control panels can be set in different places according to the engineering design requirements to prevent a single person from misoperation. Impact on operational safety. figure 1 After obtaining the local operation authorization, confirming that the signaling system is not working properly, and confirming that no train is in the switch area or is about to enter the switch area, the confirmation personnel can press the request local control button on the switch confirmation control panel. Turnout maintenance personnel are available at figure 2 Operate the toggle switch in the shown “local switch control panel” to switch the entire switch control circuit to the loc...

[0056] Example: Reference image 3

[0057] The centralized control mode is isolated from the local control mode by switching the relay. The control state of the current turnout control is controlled by the signal system in the centralized control mode. If it is necessary to switch to the local control mode, after manually confirming the operation safety of the turnout, all outdoor signal equipment is reversed to the local control circuit, and the local Turnout control circuit to control outdoor equipment. Connect the outdoor turnout point machine to different control modes through different contacts of the switching relay (QJ). Since the centralized control mode and the local control mode belong to the same safety system, and the safety level on both sides is the same, according to this feature, a polarized relay (also known as a polarity maintaining relay) will be used in the circuit design. After the coil of the polarized relay is excited by the positive current, the arm...

Abstract

The invention relates to a turnout control method and device for a rail transit signal system, according to the method, the maintenance operation of a turnout is performed through a local turnout control device under the condition that the turnout control command of the signal system fails or the signal system confirms to agree with the local control of the turnout. Compared with the prior art, the method has the advantages that the requirement for locally controlling the turnout is met, and meanwhile, the safety of maintenance personnel and operation is ensured.
