Description

Technical Field

[0001] The present invention belongs to the technical field of train safety protection, and in particular relates to an axle counting equipment application expansion system and method. Background Art

[0002] In the steel wheel and steel rail standard rail transit system, the track circuit is used as the standard system for train idle / occupancy inspection. In some switch sections, trains mainly pass through the main line section, and there is basically no train passing through the siding for a long time, which will cause the siding rails to rust and cause poor track circuit branching. The current common solutions are rail surface spraying, cladding welding, high-voltage pulses, and increasing the working voltage to break through the rust layer. All of these have certain limitations and cannot be eradicated. The use of an axle counting system can fundamentally solve the problem of poor branching, but the initial investment cost is high. The main line passing car does not need an axle counting system, and the addition of an axle counting system increases the failure points. These two problems need to be well solved, and the large-scale application of axle counting equipment to solve the poor siding branching of the steel wheel and steel rail standard will become possible.

[0003] With the rapid development of non-steel wheel and steel rail transit such as maglev, rubber-wheeled trams (Cloud Rail, Cloud Bus, straddle-type monorail, etc.), and suspended skyrail in recent years, axle counting has been widely used as a standard backup mode for urban rail transit. In these applications, due to the overall swing of the beam in the turnout section, the flapping beam usually uses more metal components, and axle counting points cannot usually be installed, and the up and down trains cannot be physically divided. In order to ensure that the up and down trains do not affect each other and the normal occupancy / idleness of the crossing line trains, it is usually achieved by collecting the turnout status and adding logical processing.

[0004] In view of the above situation, at present, some scenarios are realized by collecting the switch status and performing conditional logic axle counting, but there is no overall systematic technical solution. Most of them are based on the current general axle counting system and customized for some scenarios. Due to the large number of various switch section types and switch indication relays, the axle counting processing unit must collect and process all these switch indication relay states. The hardware interface is insufficient, and the software design is complex and difficult. In engineering design, the switch status is usually collected and judged by the logical combination of multiple series and parallel connections of the switch positive / negative indication relay contacts. When the collected positive / negative tables are all in the falling state, it is difficult to judge whether the switch is Whether it is really in the four-open state or there is an error in the collection, it is mostly treated as the four-open state. Only when the car passes can it be identified that there is an error in the collection state, and the fault cannot be handled in advance. The processing of some special turnouts will make the hardware serial and parallel logic more complicated. Due to the complexity of the engineering design of multiple serial and parallel connections, some special turnout application scenarios and user needs may not be met due to hardware limitations, and adaptive development is required again, and it is usually no longer compatible with the original equipment. Otherwise, the user is required to change the requirements and make interlocking adaptive modifications at the same time. The engineering difficulty and complexity are high, and standardized and modular design have not been achieved, which seriously restricts the promotion and application of axle counting products in these special application scenarios. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides an axle counting equipment application expansion system and method, which adopts a systematic design thinking to solve the problem of poor branching of axle counting equipment in steel wheel and steel rail standard rail transit systems and the difficult problem of standardized and modular design in the application of non-steel wheel and steel rail rail transit turnout sections.

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is: an axle counting equipment application expansion system, comprising:

[0007] The interface logic processing unit motherboard is used to collect the upper and lower contact information of the turnout setting and reverse indication relay, and transmit it to the interface logic processing unit for turnout state judgment processing, and select multiple modes through the mode selection dial group, wherein the mode selection dial group is used to select the turnout application type;

[0008] The interface logic processing unit is used to perform logic processing on different turnout types and formulate different processing logics for different types of turnouts through the status identification of the upper and lower contacts of the turnout reverse indication relays collected by the motherboard of the interface logic processing unit, and formulate corresponding mode codes, wherein each type corresponds to a software modular design, and in each mode, according to the turnout state, the information of the axle counting points that need to be processed for axle counting in this state and the axle counting points that only need to be judged by the background are transmitted to the axle counting host unit for axle counting logic processing, and the turnout fault information is transmitted to the axle counting host unit, and the working status information, fault information and alarm information are transmitted to the centralized monitoring equipment;

[0009] The motherboard of the axle counting host processing unit is used to collect the information of the axle counting point sensors and transmit it to the axle counting host processing unit for section occupation / idle judgment. The motherboard of the axle counting host processing unit includes an input-end and output-end dialing group and an application selection dialing group. The input-end and output-end dialing group is used to set the input and output of multiple connected sensors; the application selection dialing group is used to select multiple turnout application types;

[0010] The axle counting host processing unit is used to set the mode corresponding to the interface logic processing unit by applying the selection dial group, and receive the axle counting points that need to be processed by the interface logic processing unit in real time under the current turnout type mode, the axle counting point information that only needs to be judged by the background, and the turnout fault information. According to the collected axle counting point sensor information, after the logical axle counting judgment, the track occupation / idle status is transmitted to the interlocking device, and the working status information, fault information and alarm information are transmitted to the centralized monitoring device;

[0011] Interlocking device, used to perform interlocking logic processing on track idle / occupied status, and provide reset information to the axle counter host processing unit when the axle counter host processing unit needs to be reset;

[0012] Centralized monitoring equipment, receiving interface logic processing unit, axle counting host processing unit working status information, fault information and alarm information for fault handling and maintenance.

[0013] The beneficial effects of the present invention are as follows: the interface logic processing unit in the present invention performs modular design on the processing logic under each turnout type mode, and encodes each mode, and selects up to 64 turnout types through the interface logic processing unit motherboard MB1 mode selection dial group (6 bits) and the axle counting host processing unit motherboard MB2 application selection dial group (6 bits), which is used for matching the interface logic processing unit mode with the axle counting processing unit mode. According to the turnout state, the axle counting points that need to be processed for axle counting in this state and the axle counting points that only need to be judged in the background are transmitted to the axle counting unit for axle counting logic processing. This design can classify known turnout types into modular designs and manage them through mode coding. When encountering a situation that the existing mode cannot meet the requirements, the corresponding processing logic can be added to the existing software, and the mode coding can be performed, so that the axle counting device can be continuously iterated and upgraded with full backward compatibility through modular design in the special turnout processing application field, which solves the current disadvantages of different software and different processing logic for different turnout types.

[0014] Furthermore, the interface logic processing unit motherboard includes:

[0015] The mode selection dial group subunit is used to select 64 modes through the mode selection dial group, and is used to match the interface logic processing unit mode with the axle counter processing unit mode by corresponding to the switch type of the application selection dial group;

[0016] The switch reverse indication relay contact collection subunit is used to collect information on the upper and lower contacts of multiple groups of switch reverse indication relays, and transmit the collected information to the interface logic processing unit for switch status judgment processing.

[0017] The beneficial effect of the above further scheme is: by matching the mode selection dial group of the interface logic processing unit motherboard MB1 with the application selection dial group switch type of the axle counting host processing unit motherboard MB2, a modular design matching of the interface logic processing and the axle counting host processing is achieved.

[0018] Furthermore, the interface logic processing unit includes:

[0019] The mode selection dial group acquisition subunit is used to read the mode configuration information of the mode selection dial group to provide support for logical judgment;

[0020] The turnout inversion table collection and route judgment logic processing sub-unit is used to collect the status identifications of the upper and lower contacts of each turnout inversion indication relay, and make judgments in combination to determine the current route status, and to sort the axle counting point codes at the input end and the output end on the preset route, and encode the axle counting points on the route that need to be counted and the axle counting points that only need to be processed in the background, and correspond them with the axle counting point codes of the axle counting host processing unit.

[0021] The beneficial effect of the above further scheme is: by judging the state of the turnout reverse indication relay and combining the turnout type coding and the sequential coding of the axle counting points on the approach, a modular design matching of the interface logic processing and the axle counting host processing is achieved.

[0022] Furthermore, the current route status is determined as follows:

[0023] Based on the collected information of the upper and lower contacts of the turnout reverse indication relay, when the upper and lower contacts of the turnout reverse indication relay are collected in the same way, the conditional collection is correct, which is used to correctly judge the state of the turnout reverse indication relay. Otherwise, the relay collection fails.

[0024] For the switch fixed and reverse relay states, when the fixed meter is sucked up and the reverse meter falls, the switch state is in the fixed state; when the fixed meter falls and the reverse meter is sucked up, the switch state is in the reverse state; when both the fixed meter and the reverse meter fall, the switch state is four-open, so as to obtain the switch state;

[0025] According to the turnout status, determine the current route direction, where the route direction includes:

[0026] The first state - the first route; the second state - the second route; the third state - the third route; the fourth state - no route to be processed; the fifth state - other 4 open states, where the others are states other than the first to fourth states.

[0027] The beneficial effect of the above further scheme is: by collecting and logically judging the upper and lower contacts of all turnout reverse indication relays, the status information of all turnouts can be judged more accurately, abnormal information can be collected, etc., thereby improving the collection reliability of the system and the safety of judgment.

[0028] Furthermore, the axle counting points on the preset route are sorted by the codes of the input axle counting points and the output axle counting points, which is specifically:

[0029] The first input axle counting point, the second input axle counting point, the first output axle counting point, the second output axle counting point and the third output axle counting point are respectively set, and the second input axle counting point and the first output axle counting point are located in the first state-first approach, the first input axle counting point and the second output axle counting point are located in the second state-second approach, the first input axle counting point and the third output axle counting point are located in the third state-third approach, and the second input axle counting point and the second output axle counting point are located in the fourth state-no processing approach;

[0030] Regarding the specified positions of the first input axle counting point, the second input axle counting point, the first output axle counting point, the second output axle counting point and the third output axle counting point, it is necessary to ensure that the positions of the axle counting host processing unit and the interface logic processing unit in the route configuration are consistent to complete the encoding.

[0031] The beneficial effect of the above further scheme is: through the sequential coding of the input axle counting point and the output axle counting point, and through the corresponding matching of the coding with each approach, the standardization and modular design of this type of turnout can be completed. In practical applications, in turnouts similar to this type, it is only necessary to perform sequential matching access of the input axle counting point and the output axle counting point on the motherboard of the axle counting host processing unit, and by selecting the mode dial code of this application, the engineering matching design can be completed.

[0032] Furthermore, the axle counting host processing unit motherboard includes:

[0033] The application selection dial group subunit is used to select 64 modes through the application selection dial group, and is used to match the interface logic processing unit mode with the axle counter processing unit mode by corresponding to the switch type of the mode selection dial group;

[0034] The sensor access terminal subunit is used to collect data from multiple axle counting points, transmit the collected information to the axle counting host processing unit for axle counting logic processing, and is used by the axle counting host processing unit to make section occupied / idle judgment;

[0035] The input and output dial group subunit is used to set the input and output of multiple axle counting points, and transmit the setting information to the axle counting host processing unit for axle counting logic processing. Among them, the sensor access point position and the input and output dial information must be completely corresponding to the input and output axle counting point settings in the interface logic processing unit.

[0036] The beneficial effect of the above further scheme is: through the interface logic processing unit motherboard MB1 mode selection dial group and the axle counting host processing unit motherboard MB2 application selection dial group switch type correspondence, and the input and output sensor coding sequence correspondence, the modular design matching of the interface logic processing and the axle counting host processing is realized.

[0037] Furthermore, the axle counting host processing unit includes:

[0038] The application selection dial code acquisition subunit is used to read the application selection dial code group mode configuration information to provide support for logical judgment;

[0039] The axle counting point information collection subunit is used to receive the axle counting point information and the axle counting point input and output dial setting information in real time under the turnout type mode by applying the selected dial group setting corresponding to the mode of the interface logic processing unit, and collect and process the axle counting point information that needs to be processed;

[0042] The alarm output unit is used to transmit working status information, fault information and alarm information to the centralized monitoring device to facilitate equipment maintenance.

[0043] The beneficial effect of the above further scheme is: the modular matching design of the interface logic processing and the axle counting host processing is realized by applying the selection dial code judgment, the axle counting input and output and the route.

[0044] The present invention also provides an axle counting device application expansion method, which is applied to an axle counting device application expansion system, and comprises the following steps:

[0045] S1, collecting the status identification of the upper and lower contacts of each turnout reverse indication relay through the interface logic processing unit motherboard, wherein the interface logic processing unit motherboard includes a mode selection dial group for selecting the turnout application type;

[0046] S2. The axle counting point sensor information for determining section occupancy / idleness is collected through the axle counting host processing unit motherboard, wherein the axle counting host processing unit motherboard comprises an input-end and output-end dialing group for setting the input-end and output-end of the connected multiple sensors; the axle counting host processing unit motherboard comprises an application selection dialing group for selecting multiple turnout application types;

[0047] S3, the interface logic processing unit, through the interface logic processing unit motherboard collected each turnout fixed reverse indicating relay upper and lower contact status identification, performs logic processing on different turnout types and formulates different processing logics for different types of turnouts, and formulates corresponding mode codes, wherein each type corresponds to a software modular design, and in each mode, according to the turnout state, the axle counting points that need to be processed in this state and the axle counting points that only need to be judged in the background are transmitted to the axle counting host unit for axle counting logic processing, and the turnout fault information is transmitted to the axle counting host unit, and the working status information, fault information and alarm information are transmitted to the centralized monitoring equipment;

[0048] S4. The axle counting host processing unit, by applying the selection dial group to set the mode corresponding to the interface logic processing unit, receives in real time the axle counting points that need to be processed and the axle counting point information and the turnout fault information that only need to be judged in the background under the current turnout type mode, and after logical judgment, transmits the track idle / occupied status to the interlocking device, and transmits the working status information, fault information and alarm information to the centralized monitoring device.

[0049] The beneficial effect of the above further scheme is: the interface logic processing unit in the present invention modularizes the processing logic under each turnout type mode and encodes each mode, and selects up to 64 turnout types through the interface logic processing unit motherboard MB1 mode selection dial group (6 bits) and the axle counting host processing unit motherboard MB2 application selection dial group (6 bits), which is used to match the interface logic processing unit mode with the axle counting processing unit mode. According to the turnout state, the axle counting points that need to be processed in this state and the axle counting points that only need to be judged in the background are transmitted to the axle counting unit for axle counting logic processing. This design can classify known turnout types into modular designs and manage them through mode coding. When encountering a situation that the existing mode cannot meet the requirements, the corresponding processing logic can be added to the existing software and the mode coding can be performed, so that the axle counting equipment can be continuously iterated and upgraded with complete backward compatibility through modular design in the special turnout processing application field, which solves the current disadvantages of different software and different processing logic for different turnout types.

[0050] The present invention can modularly design new turnout processing types according to the subsequent increasing special application types. It only needs to add corresponding software module designs in the interface logic processing unit and the axle counting host logic processing unit, and correspondingly perform new mode encoding. During use, it only needs to perform corresponding dial matching designs on the interface logic processing unit motherboard MB1 and the axle counting host processing unit motherboard MB2. The newly added module function does not affect the existing turnout type mode and is fully compatible with existing applications, thereby providing a good solution for axle counting in special application fields.

[0051] Furthermore, the processing logic flow of the interface logic processing unit is as follows:

[0052] A1. Initialization, collecting the mode selection dial group information of the interface logic processing unit motherboard;

[0053] A2. Compare the mode selection dial group information with the application selection dial group information to provide support for logical judgment;

[0054] A3. Collect the information of the turnout reverse indication relay, and make a state judgment based on the comparison result, and select the route according to the combination of the upper and lower contact status identification of each turnout reverse indication relay, and determine the axle counting points that need to be counted and the axle counting points processed in the background according to the route selection;

[0055] A4. The turnout fault status, the axle counting points that need to be counted, the axle counting points processed in the background, and the mode configuration information are transmitted to the axle counting logic processing and judgment subunit, and at the same time, the working status information, fault information and alarm information are transmitted to the centralized monitoring equipment for easy equipment maintenance.

[0056] The beneficial effect of the above further scheme is: through the judgment of the turnout status, the current route status of the turnout can be determined, and through the matching design of the advance mode selection dial group and the application selection dial group, the current turnout fault status, the axle counting points that need to be counted, the axle counting points processed in the background, and the mode configuration information can be accurately transmitted to the axle counting logic processing judgment subunit for axle counting logic operations.

[0057] Furthermore, the modular design process of the interface logic processing unit is as follows:

[0058] B1, collect the fixed table information and reverse table information of P01, P02, and P03 turnouts respectively, and judge whether the upper and lower contact states of the fixed table / reverse table are consistent. If they are inconsistent, it is judged that there is a fixed and reverse table collection failure, and enter step B3. If it is determined to be consistent, record one of the three states of state information positioning, reverse position and four-open, and enter B2;

[0059] B2. According to the recorded results, query the route data table:

[0060] First state - first approach: P01 positioning, P02 positioning, P03 reverse position, the second input axle counting point and the first output axle counting point start axle counting;

[0061] Second state - second approach: P01 reverse position, P02 positioning, P03 positioning, the first input end axle counting point and the second output end axle counting point start axle counting;

[0062] The third state - the third route: P01 reverse position, P02 reverse position, P03 any state, the first input end axle counting point and the third output end axle counting point start axle counting;

[0063] Fourth state - no need to process the route: P01 positioning, P02 positioning, P03 positioning, and no axle counting points are counted;

[0064] The fifth state - other report 4 open states, the other states are states other than the first state to the fourth state;

[0065] B3. The fault information of the first route, the second route, the third route, the route that does not need to be processed, the four-open fault and the fixed reverse table is transmitted to the axle counting host processing unit through the transmission processing unit.

[0066] The beneficial effect of the above further scheme is: through the preset of 5 kinds of status information, 4 possible route states and 1 non-route state are preset. This preset is modularly designed into the interface logic processing unit and is also synchronously designed into the axle counting host processing unit. It can smoothly complete the delivery of several simple states of the route, and can complete the originally complex information interaction and logical operations, thus realizing the modular design of the software.

[0067] Furthermore, the processing logic flow of the axle counting host processing unit is as follows:

[0068] C1, initialization, collecting the application selection dial group information and input and output dial group information of the axle counting host processing unit motherboard;

[0069] C2. Compare the mode selection dial group mode with the application selection dial group mode;

[0070] C3, collect the information of the axle counting point sensor, and make wheel information judgment based on the comparison result;

[0071] C4. Based on the wheel information judgment result, the receiving interface logic processing unit determines the axle counting point that needs to be counted, the axle counting point information processed in the background, and the turnout fault status information according to the route selection, and performs corresponding logic processing:

[0072] Logical axle counting and fault judgment processing are carried out through the axle counting points on the approach that need to be counted. When the number of counted axles is equal and there is no fault, the track idle state is transmitted to the interlocking device; when the number of counted axles is unequal, there is a fault at the axle counting point on the approach, there is a turnout fault or a system fault, the track occupancy state is transmitted to the interlocking device; when a sensor fault of the axle counting point is collected for background processing, an alarm message is output to the centralized monitoring without affecting the track occupancy / idle state on the approach; the reset information of the interlocking device is received and synchronously transmitted to the interface logic processing unit, the section occupancy / idle information is output to the interlocking device, and the working status information, fault information and alarm information are synchronously transmitted to the centralized monitoring device.

[0073] The beneficial effect of the above further scheme is: by comparing and matching the mode selection dial group mode with the application selection dial group mode, the interface logic processing unit determines the axle counting points that need to be counted according to the route selection, the axle counting point information processed in the background, and the reception of the switch fault status information, and by performing logical axle counting processing on the axle counting points that need to be counted on the route, the occupancy / idle information and fault information of the route are accurately given, and the status is output to the interlocking; the axle counting points that need to be processed in the background do not affect the occupancy / idleness of the route, but the fault status information can be output to the centralized monitoring to promptly notify the maintenance in advance, so as to avoid affecting the normal occupancy / idle function of the equipment.

[0074] Furthermore, the processing logic of the axle counting host processing unit is as follows:

[0075] D1, receiving the first route, the second route, the third route, the route that does not need to be processed, the four-open fault and the fixed reverse table to collect fault information;

[0076] D2. Based on the received results, query the route data table:

[0077] First state - first approach: P01 positioning, P02 positioning, P03 reverse position, the second input axle counting point and the first output axle counting point start axle counting;

[0078] Second state - second approach: P01 reverse position, P02 positioning, P03 positioning, the first input end axle counting point and the second output end axle counting point start axle counting;

[0079] The third state - the third route: P01 reverse position, P02 reverse position, P03 any state, the first input end axle counting point and the third output end axle counting point start axle counting;

[0080] Fourth state - no need to process the route: no axle counting points are counted;

[0081] The fifth state - 4 open state, not counting the axis;

[0082] When the reverse table collects fault information, the system fault is determined. Before checking the data table, the application selection dial group mode setting must be consistent with the mode selection dial setting of the interface logic processing unit, and the sensor access sequence and input and output setting information must be consistent with the preset sequence in the interface logic processing unit.

[0083] The beneficial effect of the above further scheme is: through the preset of 5 kinds of status information, 4 possible route states and 1 non-route state are preset. This preset is modularly designed into the axle counting host processing unit and is also synchronously designed into the interface logic processing unit. It can smoothly complete the delivery of several simple states of the route, and can complete the originally complex information interaction and logical operations, thus realizing the modular design of the software.
