Example Embodiment

[0043] specific embodiment

[0044] figure 1 The circuit control flow chart is shown for the interlocking system and switch control, figure 2 It is the flow chart for judging the missing table and the squeezed switch for the interlocking system.

[0045] Step 1. The interlocking system issues an operation switch command;

[0046] Step 2. The relevant relays DCJ and YCJ, or FCJ and YCJ are sucked up;

[0047] Step 3. The switch control circuit is connected, the 1DQJ is electrified to pick up, and the switch machine motor is electrified to start;

[0048] Step 4. The 2DQJ is charged up, and the action lever of the switch machine moves;

[0049] Step 5. The switch machine indicates that the rod moves with the tip rail;

[0050] Step 6. The switch machine controller judges whether the tip rail is closely attached and locked, if yes, go to Step 7, if not, go to Step 9;

[0051] Step 7. The inspection column of the automatic switch machine of the switch machine falls into the c...

Abstract

The invention relates to an alarm distinguishing method for turnout split and loss representation of urban rail transit, which comprises the following steps that: step 1) during access handling or turnout operation, an interlocking system sends out a turnout action instruction, and a turnout and related equipment perform corresponding actions; (2) the interlocking system judges the positioning andreversing states of the turnout by collecting nodes of a DBJ representation relay or an FBJ representation relay; (3) the interlocking system judges whether the turnout loss state exceeds a set valueor not, and if yes, it is determined that the turnout is in a turnout split state; and (4) the interlocking system collects a turnout area occupation clearing indication relay, further determines whether it is occupation split or loss representation split, and transmits information to an ATS, and the ATS performs related split alarm or loss representation alarm. Compared with the prior art, the method has the advantages that the fault influence operation time can be reduced as much as possible, and the fault first-aid repair time can be shortened.

Description

technical field [0001] The invention relates to an urban rail transit signal system, in particular to an alarm distinction method for urban rail transit turnout squeeze and failure indication. Background technique [0002] A turnout is a line connection device that allows locomotives to transfer from one track to another, and it is also one of the weak links of the track; a turnout refers to that when a train passes through a turnout in a straight line, the point rail fails to connect with the turnout due to the incorrect position of the turnout. The basic rails are closely attached. When the wheels are rolled, the point rails and the basic rails are squeezed apart. At this time, the turnout is neither in position nor reversed, and is in a four-way state, which can easily lead to derailment and overturning of the train. [0003] In the event of a traffic jam, the signaling system will shut down the signal machine and not allow the train to enter the traffic jam area. At the...
