Description
Technical Field
The invention belongs to the technical field of safety, particularly relates to train receiving and dispatching safety when railway interlocking fails, and particularly relates to a method for confirming a turnout opening position when the interlocking fails.
Background
In the railway train receiving and dispatching work, under normal conditions, an operator arranges the access through an interlocking console, remotely and electrically switches the turnouts, and confirms the opening positions of the turnouts on the railway site through the colors displayed by turnout indication lamps on the interlocking console and the light bands of the access. When the interlocking fails or the interlocking console fails due to the turnout fault, an operator cannot operate the turnout through the interlocking console and confirm the opening position of the turnout. According to the regulation requirements, when the interlocking fails or power is cut off, a train receiving and dispatching commander must send a person to serve as a switchman, and the switchman arrives at the railway site to confirm the turnout opening position on site and report the turnout opening position to the commander. If the switch opening position is incorrect, the switchman must hand the switch according to the specification and then report to the commander.
The correct switch-on position is the key to ensure the safety of train receiving and dispatching. In order to prevent accidents caused by human errors, strict 'reconfirmation' and 'double confirmations' systems are established for railway aiming at confirming switch opening positions when interlocking fails or an interlocking console is powered off. The reconfirmation means that the work flow of confirming that the switch opening position is correct and reporting to the commander by the switchman must be done twice. By double confirmation is meant that the conditional station double confirmation report cannot be the same person. The above confirmation system completely depends on people, so that not only is potential safety hazard existed, but also the working efficiency is influenced, and the management is difficult.
Disclosure of Invention
The invention provides a method for confirming and reporting the turnout opening position by scanning a turnout opening position bar code placed on a turnout in advance by utilizing a modern communication network technology, aiming at solving the problem of turnout opening position confirmation in the process of the existing train receiving and dispatching failure or power failure of an interlocking control console, so as to avoid human errors of a switchman, ensure the driving safety and improve the operation efficiency.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for confirming the switch-on position of a turnout when interlocking fails is characterized by comprising the following steps:
the first step is as follows: compiling and setting a bar code of a station turnout opening position, and specifically comprising the following steps:
step 1.1: establishing a bar code corresponding to the opening position of each turnout according to a station;
step 1.2: setting a turnout position bar code on each turnout of a station;
the second step is that: establishing a database of the relationship between the receiving and dispatching routes and the turnout opening positions, which specifically comprises the following steps:
step 2.1: characteristic information describing the route;
step 2.2: establishing the association between each train receiving and dispatching route and a turnout;
the third step: and determining whether the on-site turnout opening position is correct or not according to the station turnout opening position bar code and a train receiving and dispatching approach and turnout opening position relation database.
In order to optimize the technical scheme, the specific measures adopted further comprise:
further, in step 1.1, the bar code corresponding to the turnout opening position includes the following six-bit code: the first bit represents the yard number; the second, third and fourth digits represent turnout numbers; the fifth bit indicates the switch type, where 1 indicates a fixed frog switch and 2 indicates a movable point switch; the sixth bit indicates the on direction, where 1 indicates the switch rail on position, 2 indicates the switch rail on reset, 3 indicates the movable point rail on position, and 4 indicates the movable point rail on reset.
Further, in step 1.2, the barcode is disposed at a position where the fixed component of the switch and the movable component of the switch are overlapped in the vertical direction, so as to ensure that when the movable component of the switch opens a specific position, only the barcode at the position where the movable component opens the specific position can be scanned, and the barcodes at other positions cannot be scanned due to shielding.
Further, in step 2.1, the characteristic information of the route includes direction, up-down movement, and station tracks for train receiving and dispatching.
Further, in step 2.2, the association between each train receiving and dispatching route and each turnout is established through a turnout opening position bar code, and the association between the routes and the turnouts comprises which turnouts are associated, the types of the associated turnouts and the opening positions of the associated turnouts; and establishing correct switch opening position positioning and reverse color display in a database according to the switch opening position bar code, wherein the positioning display is green, and the reverse display is yellow.
Further, the third step specifically comprises:
step 3.1: confirming route characteristic information for train receiving and dispatching;
step 3.2: confirming the number of the fault turnout;
step 3.3: and calling database information of the relationship between the route and the opening position of the fault turnout, wherein the database information comprises a turnout opening position bar code corresponding to the number of the fault turnout in the database and a correct turnout opening position positioning and reversing color.
Step 3.4: inputting a bar code of an actual fault turnout opening position through field scanning;
step 3.5: comparing the actual fault turnout opening position bar code with the turnout opening position bar code called in the database, and correspondingly displaying the color of the positioning and reversing position of the actual fault turnout opening position;
step 3.6: and comparing the positioning and reversing color of the actual fault turnout opening position with the positioning and reversing color of the correct turnout opening position called in advance, wherein the same color indicates that the on-site turnout opening position is correct, and otherwise, the turnout opening is wrong.
Further, in step 3.4, a switchman prepares the turnout according to the specification on the railway site and confirms the turnout opening position, and the bar code of the actual fault turnout opening position which can be seen is scanned by using the bar code scanning input device.
Further, in step 3.5, if the same turnout corresponding to the number of the failed turnout called from the database only has one bar code and the comparison is correct, the color of the actual opening position of the failed turnout is changed from the red indicating the failure to the color of the opening position of the turnout, namely the last code of the bar code is 1 to display green and 2 to display yellow; if the same turnout is called from the database and has two bar codes and only one bar code is compared correctly, the display of the opening position of the actual fault turnout is changed from red to red flash; if the database calls that the same turnout has two bar codes and the comparison of the two bar codes is correct, the display of the actual fault turnout opening position is changed from red to the color of the turnout opening position, namely the last bit of the bar code is 1 or 3 to display green, and 2 or 4 to display yellow.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
The method for confirming the turnout opening position in the case of linkage failure provided by the invention comprises three steps, specifically as follows:
the first step is as follows: compiling and setting station turnout opening position bar code
1. Establishing bar code corresponding to each turnout opening position according to station
The railway station turnout serial numbers are sequentially numbered from the two ends of the station from outside to inside. The arrival ends of the ascending trains are coded into an even number, and the arrival ends of the descending trains are coded into an odd number. When a station has a plurality of stations, the switches of each station are numbered independently, and the first digit of the switch number is the station number.
The switches for receiving and dispatching trains are all common single-opening switches, have two different opening directions, and are called positioning and reverse positioning of the switches respectively.
In order to eliminate the harmful space of the switch, the switch has two types of fixed frog switch and movable point rail switch.
The coding method of the turnout opening position is shown in the table 1.
TABLE 1 coding method for turnout opening position
For example, the code "000312" indicates that the station is not separated, the 3 # turnout is a fixed frog, and the switch rail is turned on and off. The code "202423" indicates the switch point rail switch open position No. 24 of yard 2. The two-way bar code with the same dimension is shown in FIG. 1.
2. Setting a point position bar code on each point of a station
The switch tongue and the movable point rail have two positioning and reverse directions, namely 1 and 2, 3 and 4. In order to ensure that the opening position of the switch rail or the movable point rail represented by the bar code is completely consistent with the actual opening position when the bar code is scanned by a switchman to report the opening position of the switch, the bar code is arranged at the position where the fixed part (the stock rail, the switch tie and the switch machine fixing seat) of the switch and the movable part (the switch rail, the movable point rail and the switch machine connecting rod) of the switch are overlapped in the vertical direction, so that the bar code of the opening position can only be scanned by the switchman when the switch rail and the movable point rail are opened at the specific position, and the bar code of the other position cannot be scanned due to the shielding of the upper parts. As shown in fig. 2, two bar codes associated with the switch open position are placed on the tie between the point rail and the stock rail. No matter which position the switch is opened, the switchman can only see and scan the bar code corresponding to the switch opening direction due to the shielding of the switch rail. The reference numerals in the figures are as follows: 1. an action link; 2. an electric switch machine; 3. a bar code can be scanned; 4. a stock rail; 5. a switch tie; 6. a blocked bar code; 7. a point rail.
The second step is that: establishing a database of the relationship between the receiving and dispatching routes and the turnout opening positions
1. Characterizing information describing routes
The route characteristic information includes direction, up-down movement and station track for train receiving and dispatching.
2. Establishing the association between the route and the turnout of each train
The association of the approach and the turnouts comprises three levels, namely, which turnouts are associated, the types of the turnouts are associated, and the opening positions of the associated turnouts are associated. All three associations can be replaced by switch on position codes. In order to enable a train commander to visually determine the opening position of a turnout, the system establishes a correct turnout opening position positioning and inverting display database, the positioning display is green, and the inverting display is yellow so as to be compared with the actual operation condition.
The third step: software system for developing wireless input switch position manual confirmation report
1. Confirming route characteristic information for train departure and reception
The route characteristic information confirmation content comprises direction, up-down line and station track for train receiving and dispatching.
2. Confirming numbers of faulty switches
The interlocking failure caused by the turnout fault is usually the fault of a single turnout, so the number of the fault turnout needs to be confirmed. If the interlocking console is powered off, all turnout faults must be confirmed.
3. Calling the information of the database of the relationship between the route and the opening position of the fault turnout
After the access characteristic information and the number of the fault turnout are confirmed, the system can code the turnout opening position in the database corresponding to the number of the calling fault turnout. And simultaneously calling the color display of the correct turnout opening position of the fault turnout so as to compare the color display with the actual operation condition.
4. Scanning bar code input for fault turnout opening position
The switchman prepares the turnout and confirms the turnout opening position according to the regulations on the railway site, and after the visible turnout opening position bar code is scanned by using the bar code scanning input equipment, the system can directly send the scanned code to the signal building information receiving platform through the digital wireless network. To prevent errors caused by manual entry of codes, scanning devices do not support manual entry.
5. Switch opening position code comparison
And the signal building information receiving platform compares the received turnout opening position bar code codes with the turnout opening position codes called by the database one by one. If only one code (indicated as a fixed switch-off switch) of the same switch is called from the library and the comparison is correct, the display of the actual switch-on position is changed from red to the color of the switch-on position, namely the last code is 1 to green and 2 to yellow. If the same switch is called from the library with two codes (denoted as movable point switches) and only one alignment is correct, the actual switch on position display will change from red to red flashing. If the same turnout is called from the library and has two codes and the two codes are compared correctly, the display of the actual turnout opening position is changed from red to the color of the turnout opening position, namely the last bit of the input code is 1 or 3 to display green, and 2 or 4 to display yellow.
6. And comparing the positioning and reversing color of the actual turnout opening position with the positioning and reversing color of the correct turnout opening position called by the system in advance, wherein the same color indicates that the on-site turnout opening position is correct, and otherwise, the turnout opening is wrong.
The working flow of the fault switch scanning bar code confirmation reporting system is shown in figure 3.
Fig. 4 is a schematic view of a control station of a two-wire automatic block railway station. The station turnouts are all movable point rail turnouts and are positioned by opening a positive line. Now, the failure of interlocking caused by the fault of No. 9 turnout, and the implementation process of the invention is illustrated by that G705 times of trains coming in the Beijing direction enter 3 stops.
The first step is as follows: compiling and setting station turnout opening position bar code
1. And establishing a bar code corresponding to the opening position of each turnout according to the station.
For example, there may be four bar codes for switch 9, and the codes are: switch rail on position 000921, switch rail on inverted position 000922, point rail on position 000923 and point rail on inverted position 000924.
2. And setting corresponding bar codes on each turnout of the station according to the requirements.
The second step is that: establishing a database of the relationship between the receiving and dispatching routes and the turnout opening positions
Taking the example of the way of getting on the vehicle 1, 3 and 4 in the Beijing direction, the database is established.
TABLE 2 example of relationship database between route and turnout opening position
The third step: software system for manually confirming and reporting positions of running wireless input turnouts
1. And confirming that the access characteristic information for the train receiving and dispatching is that the downlink train which is opened in the Beijing direction enters 3 paths.
2. And confirming that the number of the fault turnout is 9 turnouts.
3. The system calls the information of the database of the relationship between the route and the opening position of the fault turnout in the table 3.
Table 3 calling database information of relations between routes and open positions of faulty switches
| Direction | Uplink and downlink | Track for stock | Turnout and correct positioning reverse color | Non-interlocking switch position coding | |
| | Downstream | 3 | 9 (yellow) | 000922、000924 |
The system platform display at this point is shown in figure 5. The lower yellow light indicates that the correct opening position of the 9 th turnout is in the reverse position. The upper red light indicates that the actual opening position of the No. 9 turnout on the railway field is not determined.
4. Scanning bar code input 9 turnout opening position
A switchman prepares a turnout of No. 9 according to the specification on a railway site and confirms the turnout opening position, and after a bar code at the first turnout opening position which can be seen is scanned by using a bar code scanning input device, the system directly sends the scanned code to a signal building information receiving platform through a digital wireless network. Since the No. 9 turnout is a movable point rail turnout, the red light on the system platform is changed into red flash at the moment. After scanning the bar code of the second switch on position which can be seen, the red flash on the system platform is changed into yellow light. At the moment, the train receiving and dispatching commander confirms that the display of the actual turnout position is consistent with the correct display given by the system through the platform, and the correct position of the No. 9 turnout on the railway site is indicated.
