Description

Technical Field

[0001] The present invention belongs to the technical field of turnout control, and in particular relates to a method, device, equipment and medium for realizing redundant control of a turnout machine. Background Art

[0002] In recent years, with the rapid development of subways, the requirements for passenger service quality have become higher and higher. Therefore, higher requirements are placed on the quality of subway signal equipment and the level of maintenance and management. At the same time, the development of subways towards high speed and intelligence will inevitably put forward more stringent requirements on the fault diagnosis technology of the switch control circuit of the trackside basic equipment.

[0003] In subway line operation, the first and last stations generally need to turn back through turnout switching. The switch machine in the switching area moves frequently, which is about dozens of times that of ordinary turnout switching. The heavy number of switching times places high demands on the switch machine hardware and control circuits. At present, all indoor circuits are single-set control circuits. If this part of the control circuit fails, the impact on operation will be greater. In recent years, urban rail construction has slowed down. Before the opening of new lines, the number of opened stations will be adjusted according to the actual passenger flow, or there will be delays in the construction of the second phase. This means that the crossover at the first / last station of the opened section has a single crossover and is a turnaround before the station. Due to the scale of civil engineering, it is actually impossible to modify the wiring to a crossover on site. When a single turnout fails here, multiple stations on this line will be affected, which has a greater impact on the operation organization and the assessment of operation and maintenance fault indicators.

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] It should be noted that the terms "first", "second" etc. in the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged in appropriate circumstances, so that the embodiments of the present application described here.

[0022] The present invention mainly performs redundant design on the control part of the traditional switch machine. The brief principle of the traditional switch machine control method is as follows: See also Figure 4 The traditional control system is a normal use system for switch machine control, which mainly controls the turnout by lifting and lowering the relay. The specific action flow (taking positioning operation as an example) is as follows: a) When the interlocking conditions for turnout operation are met, the interlocking sends a fixed operation command → DCJ↑ → 1DQJ↑ → 1DQJF↑ → 2DQJ polarity change (i.e. fixed and reverse positions change) → cut off 1DQJ (3-4 coils) to prepare for the next turnout operation.

[0023] b) The three-phase power supply is sent to the switch machine through DBQ → BHJ↑ → 1DQJ self-closing circuit is connected and keeps it sucked up.

[0024] c) During the period from when 2DQJ turns polarity and cuts off 1DQJ (3-4 coils) to when BHJ↑, 1DQJ relies on its own slow-release characteristics to keep sucking up.

[0025] d) 1DQJ↑→ three-phase AC power is sent to the motor; 2DQJ reverses polarity→ power supply phase sequence changes→ motor rotation direction changes.

[0026] e) The motor starts to rotate, the switch machine disconnects the second row of contacts, disconnects the reverse position indication circuit, and connects the first row of contacts.

[0027] f) When the turnout moves to the position, the fourth row of contacts is disconnected and the third row of contacts is connected.

[0028] g) After the fourth row of contacts is disconnected, the action circuit is cut off → BHJ↓ → 1DQJ↓ → 1DQJF↓ → connected to the positioning indication.

[0029] h) The positive half-wave of the sinusoidal AC power supply passes through the turnout representation circuit →DBJ↑.

[0030] The present disclosure provides a method for realizing redundant control of a turnout machine. Figure 1 ,include: S101: Acquire the working state of the redundant system, determine the working sequence of the redundant system as a first sequence according to the working state of the redundant system, and determine the first sequence as a switching sequence; S102: monitoring the working state of the conventional switch machine control system, and when the working state of the conventional switch machine control system is a fault state, determining the time from the occurrence of the fault state to the switching of the control system as a second time sequence; S103: Switching the conventional switch machine control system to the redundant system according to the switching sequence; the triggering start time of the first sequence is earlier than the triggering start time of the second sequence; S104: The redundant system drives the turnout according to the command logic, receives the turnout drive execution result, and uploads the status representation in the execution result to the reverse cutting system.

[0031] Specifically, in step S101, obtaining the redundant system working status includes: Executing a soft start initialization procedure on the redundant system; Reset the switch machine board contacts in the redundant system and detect the on-off information of the contacts in the switch machine board; When it is confirmed that the contacts are normally on and off, the redundant system working sequence is determined to be the first sequence.

[0032] It should be noted that the redundant control implementation method of the turnout machine adopted in the present application can be applied to industrial computers, desktop computers or similar mobile terminal devices such as mobile phones and tablets for controlling railway turnouts; the redundant system adopted in the present application can be a fully electronic system, and the specific embodiments of the present disclosure are mainly described based on the fully electronic system as the redundant system.

[0033] See also Figure 3 The redundant control implementation system of the turnout machine mainly includes: traditional control system, full electronic system, monitoring system and reverse cutting system.

[0034] The all-electronic system is a redundant system of the traditional control system. It uses the switch machine board to replace the relay to realize the functions of the start circuit, indication circuit and auxiliary circuit in the traditional control system. The switch machine action circuit is consistent with the principle of the traditional control system. The specific action process (taking positioning operation as an example) is as follows: 1) When the turnout interlocking conditions are met, the interlocking sends a fixed operation command → three-phase AC power is sent to the motor.

[0035] 2) The power supply phase sequence changes → the motor rotation direction changes.

[0036] 3) The motor starts to rotate, the switch machine disconnects the second row of contacts, disconnects the reverse position indication circuit, and connects the first row of contacts.

[0037] 4) When the turnout moves to the position, the fourth row of contacts is disconnected and the third row of contacts is connected.

[0038] 5) The interlocking system determines the turnout status based on the current and voltage conditions of X1~X5.

[0039] Specifically, in step S101, by resetting the switch machine board contacts in the redundant system, detecting the on-off information of the contacts in the switch machine board, confirming that the redundant system can normally control the switch machine turnout. When the on-off information of the contacts in the switch machine board is normal, the redundant system working sequence is determined as the first sequence. The first sequence involved in this application is a sequence that the redundant system can use to directly switch, and the first sequence is determined to be able to synchronously obtain the instructions of the interlocking device with the traditional switch machine control system; the first sequence is the preparation sequence for the redundant system to work.

[0040] When the working sequence of the redundant system is the first sequence, the redundant system and the traditional switch machine control system synchronously obtain the control instructions of the interlocking system, and the first sequence is dynamically determined; The following is an example to illustrate the timing of a redundant system.

[0041] For example, in the first time period, the second time period, the third time period and the fourth time period, wherein the first time period, the second time period, the third time period and the fourth time period are all continuous time periods, in the first time period, the redundant system determines the first timing after initialization and reset, and receives a switching instruction in the first timing of the redundant system, and the redundant system intervenes in the switch control; in the first timing of the redundant system, no switching instruction is received, that is, no switching instruction is received at the first moment of the first timing and the optimal moment, the first timing will be updated and re-determined, and when the time in the first time period is updated, the second time period is entered, and the first timing is updated in the same way, and the update process of the third time period and the fourth time period is similar, which will not be repeated here. In this way, it can be ensured that the redundant system works in the normal working range and is in the available preparation range at any time, thereby ensuring the reliability of the switching.

[0042] In some implementations, in step S102, monitoring the working state of the traditional switch machine control system includes: The indoor detection module conducts online monitoring of the turnout action voltage, indication voltage, current, power, turnout relay action sequence and turnout action curve; The outdoor detection module performs online monitoring of the indication gap, switching resistance and turnout working condition.

[0043] Furthermore, after monitoring the working status of the traditional switch machine control system, According to the monitoring results, it is determined whether the fault of the traditional switch machine control system is an indoor equipment fault or an outdoor equipment fault; Among them, a fault locating signal is transmitted to the traditional switch machine control system, the fault locating point is determined according to the feedback of the fault locating signal, and the indoor equipment fault or the outdoor equipment fault is determined according to the fault locating point.

[0044] Wherein, the method of determining an indoor device fault or an outdoor device fault according to a fault location point includes: Establishing a monitoring location map for a conventional switch machine control system, wherein the monitoring location map includes a device monitoring section of the conventional switch machine control system; The indoor equipment fault point or outdoor equipment fault point of the traditional switch machine control system is determined according to the fault location point and the monitoring section in the monitoring location map.

[0045] If the indoor equipment fails, the switching system switches to the redundant system according to the fault command and sends an alarm command to the interlocking equipment; If the indoor equipment fails, the switching system will switch to the redundant system according to the fault command and send an alarm command to the interlocking equipment.

[0046] Specifically, the monitoring system is divided into indoor monitoring module and outdoor monitoring module. The indoor monitoring module can conduct online real-time monitoring of the turnout action voltage, indication voltage, current, power turnout relay action sequence and turnout action curve. The outdoor monitoring module can conduct real-time online monitoring of indication gap, conversion resistance, turnout working condition, etc. The turnout switch control redundancy system mainly refers to the switching method when the indoor equipment fails. The monitoring system automatically locates the fault point by analyzing these main information. If it is an indoor equipment failure, it will automatically switch and alarm. At the same time, the monitoring system can also monitor the status of the entire electronic system, and alarm when a board or component fails.

[0047] See also Figure 3 and Figure 5 The reverse cutting system is installed between the traditional control system / all-electronic system and the lightning protection distribution cabinet. It is mainly used for reverse cutting between the traditional control system and the all-electronic system. The control between the two systems does not affect each other and is safe and controllable, and there is a status indicator light. The reverse cutting system is divided into two modes: automatic reverse cutting and manual reverse cutting. Automatic reverse cutting is usually used, and manual reverse cutting is used when special circumstances occur. Manual reverse cutting has a higher priority than automatic reverse cutting. The reverse cutting process is: a) DQJ stands for automatic reverse switching relay, which is a safety relay and is normally in the attracted state.

[0048] b) See Figure 6 , Automatic switching: The system is normally in traditional control mode, with a green light on; when the monitoring system determines that there is an indoor equipment failure, the system automatically drives the DQJ down, switches to the full electronic system mode, and lights up the yellow light. When the indoor equipment failure is repaired, the system automatically switches back to the traditional control mode (users can also configure it according to their own needs to automatically switch back or maintain the current state).

[0049] c) See Figure 7 , Manual switching: The reverse switch uses a keyed knob, which is set on the reverse switch system panel, and is mainly used for on-site maintenance or other special situations. When manual reverse switching is required, insert the key to activate the reverse switch button, rotate it to the required system state, and the corresponding indicator light will light up.

[0050] In step S104, the redundant system drives the turnout according to the command logic, receives the turnout drive execution result, and uploads the status representation in the execution result to the reverse cutting system. Confirm that the switch is successful, monitor the operation of the redundant system, and obtain the successful repair instruction of the traditional switch control system; When a repair success instruction sent by the traditional switch machine control system is obtained, the redundant system is switched to the traditional switch machine control system.

[0051] See also Figure 8, the switching process of the redundant control system of the turnout machine is described below with reference to the accompanying drawings.

[0052] The system is in the traditional mode. When the equipment alarm fails, the monitoring system determines that the indoor equipment is faulty and the reverse cutting system is normal, and it automatically switches to the full electronic system and issues an alarm. At this time, the control circuit of the turnout is completely controlled by the full electronic system, and the full electronic interlocking executes the command logic processing, drives the relevant turnouts, and executes them in place. After the turnout is switched in place, the relevant acquisition board collects the current status of the turnout and gives the corresponding turnout indication. At this time, the maintenance personnel can determine the temporary or skylight point to repair the relevant components of the traditional control system according to the alarm fault situation.

[0053] When the traditional control system fault is repaired, the system automatically switches back to the traditional control mode (the user can also configure it according to their own needs to automatically switch back or maintain the current state).

[0054] If the user chooses to keep the all-electronic system after the fault is repaired, the traditional control system will be the backup system. When the indoor board or other components of the all-electronic system fail, the principle of the reverse switching process is the same as a).

[0055] If the monitoring system determines that the outdoor cable, box or switch machine is faulty, the maintenance personnel will perform emergency repairs according to the fault handling process.

[0056] If the reverse switching system fails, you can switch to manual switching mode. For specific operations, see the reverse switching system principle description.

[0057] This application solves the problems of aging, high failure rate and low redundancy of existing switch control equipment, improves the increasing quality of passenger service, and provides an important guarantee for meeting the operation and maintenance assessment indicators.

[0058] The present application combines the traditional turnout control system, the fully electronic control system and the monitoring system through the reverse cutting system, thereby improving the redundancy, safety and maintainability of the turnout control, and realizing both automatic seamless switching and manual switching between the two systems.
