Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
The invention relates to a test system of a rail transit interconnection and intercommunication signal system, which is mainly divided into an off-line tool, a vehicle-mounted simulation part and a rail-side simulation part, and defines a communication interface between the vehicle-mounted simulation part and the rail-side simulation part, so that the vehicle-mounted simulation part and the rail-side simulation part can be respectively developed by different manufacturers and are integrated through a unified interface. Meanwhile, different lines are combined into the same line through an off-line tool, so that the same simulation trackside equipment software can be adopted for different lines, the problem of communication among different simulation trackside equipment in the line crossing process is not needed to be considered, and the method is simpler and stronger in comprehensiveness.
As shown in fig. 1, the test system of the rail transit interconnection and intercommunication signal system of the present invention specifically includes:
1) the test platform part of the test system is mainly divided into an off-line tool, a vehicle-mounted simulation part and a trackside simulation part. The off-line tools are divided into a simulation locomotive off-line tool, a beacon off-line tool and a simulation trackside off-line tool, and generated data is used by the simulation locomotive and simulation trackside equipment. The simulation locomotive sends the real-time position of the train to the simulation trackside equipment so as to facilitate the simulation trackside equipment to calculate the occupation and clearing states of the axle; the simulation trackside equipment sends the real-time states of trackside equipment such as turnouts, signal machines and the like to the simulation locomotive, and the simulation locomotive uses the states of the trackside equipment to run and screen beacons.
2) The main principle of the test system is that data (system data, vehicle-mounted data, LEU data, interlocking data and the like) of different interconnected lines are processed and combined into data of one line through an off-line tool, so that the data can be processed as one line. For example, the line a and the line B are interconnected, the line a (line ID is a) has m signals (number 1-m), the line B (line ID is B) has n signals (number 1-n), and if the data of the two lines are simply merged without processing, the IDs of the signals may be duplicated, so that the IDs of all line devices can be reprocessed as new IDs 10000 lineID + oldID. All IDs are thus not repeated, so that two lines can be combined into one line at the test platform end for processing. The ID discussed here is generally the ID used inside each manufacturer, actually the interconnection and intercommunication establishes an interconnection and intercommunication ID for all the devices, the interconnection and intercommunication ID is also unique for all the circuits, so the ID is not used, on one hand, the interconnection and intercommunication ID is more complicated and has weak readability because of rich information, and the test platform does not need to use so much information, and generally only care about the circuit ID and the internally used smaller ID; on the other hand, since the devices such as beacons do not have interworking IDs, they are handled uniformly in the above-described manner. The above-mentioned ID processing method is only an example, and other similar methods may be used.
3) The test system of the interconnection and intercommunication signal system is mainly divided into three parts, wherein the first part is line data of each line and mainly comprises system data, vehicle-mounted data, interlocking data, LEU data and the like; the second part is a test platform part and mainly comprises a simulation driving platform module, a simulation locomotive off-line tool module, a beacon off-line tool module, a simulation locomotive module, a simulation trackside off-line tool module and a simulation trackside equipment module; the third part is a tested signal system which mainly comprises an ATS, a ZC & DSU, a vehicle-mounted CC, an interlock and the like.

Wherein the tested object signal systems are communicated with each other by being connected to a safety net or a non-safety net. The test platforms mainly communicate with each other through a test network, and the simulation trackside equipment needs to communicate with the interlock through being connected to a signal network (a safety network and a non-safety network).
5) The simulation cab module in the test system of the interconnection and intercommunication signal system is mainly used for simulating a cab in an actual line, and mainly simulates a key KSON, a direction handle, a traction brake handle, a door opening and closing button, a button related to driving mode operation and the like. The simulation driving platform is simulation software running on a PC, is connected with the simulation locomotive through a test network, issues an operation command of a tester to the simulation locomotive, and is processed by the simulation locomotive; and meanwhile, receiving the button state information sent by the simulated locomotive.
6) The simulation locomotive off-line tool module in the test system of the interconnection communication Signal system is mainly used for combining vehicle-mounted data of a plurality of lines of interconnection and intercommunication according to the method, mainly comprises information such as turnout points, Signal signals, beacons Beacon and Block, and processes the Block link relation of critical positions of the two lines, so that a vehicle can cross to a line B from a line A. Finally, outputting the corresponding file for the simulation locomotive module to read.
7) The beacon offline tool in the test system of the interconnection communication signal system is mainly used for merging LEU data of a plurality of lines according to the method and generating a beacon screening file according to the LEU data. The LEU file defines the different beacon messages that each beacon outputs when different input conditions are met. And the beacon offline tool processes LEU data offline for the simulation locomotive to read, the simulation locomotive reads the state of the trackside equipment from the simulation trackside equipment in real time in the running process, and selects a correct beacon message in real time according to the state of the trackside equipment and outputs the beacon message to the vehicle-mounted CC.
8) The simulation locomotive module in the test system of the interconnection communication signal system mainly realizes the following functions: reading off-line files generated by the simulation locomotive off-line tool and the beacon off-line tool in an initialization stage; receiving various commands sent by the simulation driver's cab in real time; calculating the displacement of each period in real time according to an acceleration command sent by the simulation driver's cab or the vehicle-mounted CC, converting the displacement into a pulse signal and sending the pulse signal to the vehicle-mounted CC (the function of an analog coding odometer); calculating the passing position of the train according to the displacement of each period, inquiring whether the period passes through the beacon according to the line map, and generating a beacon waveform and sending the beacon waveform to the vehicle-mounted CC (function of simulating a beacon antenna) if the period passes through the beacon; simulating the input and output IO function of the vehicle; the train position is sent to the simulation trackside equipment in real time, and the trackside equipment calculates the occupation and clearing information of the axle in real time according to the train position; and receiving the state information of the trackside equipment such as turnouts, signal machines and the like from the simulated trackside equipment in real time for screening sports cars, beacons and the like.

11) The simulation trackside equipment in the test system of the interconnection communication signal system needs to receive interlocked output code bit information from the simulation interlock through the signal network and send the interlocked input code bit information to the simulation interlock through the signal network (the real interlock is directly connected to the PLC or other equipment through a hard wire, and the PLC is connected to the simulation trackside equipment through a network). The simulation locomotive and the vehicle-mounted CC are connected through a real hard wire. The rest parts of the test platform are connected through a test network and carry out mutual information interaction.
As shown in FIG. 2, the flow chart for use in the test system of the present invention comprises the following steps:
step S1: the system is used for data input of a test platform, a rail transit signal system generally comprises a plurality of subsystems, such as a vehicle-mounted CC, a trackside ZC/DSU, an interlocking CI, an ATS and the like, each subsystem has own data, and the test platform generally needs system data, vehicle-mounted data, interlocking data, LEU data and the like as input. The difference from the data input of a conventional non-interconnecting intercommunication signal system is that the data input here includes two or more line data, i.e., line 1 data, line 2 data … line n data. Each line contains a lot of real devices (such as turnout Point, Signal, shield door PSD, ESP, SPKS, etc.), each line numbers the devices, if the test platform simply merges the data without processing, the phenomenon of ID duplication occurs, so that an offline tool needs to be used to process and renumber the input data, and thus, a plurality of line data are merged into one line data.
Step S2: this is a simulated locomotive offline tool, which takes on-board data and system data as input, and renumbers all device IDs in such a way that newID is 10000 lineID + oldID, where lineID is a unique ID for each different line, oldID is a small ID used internally (generally within 10000), and newID is a regenerated ID. Thus, after merging into one for multiple lines, the ID of each device is not repeated. Note that the ID is not unique, and the main principle is that the new ID has the original ID and the line ID and is easy to identify. Meanwhile, the simulation locomotive offline tool needs to process the Block link relation at the critical position of different lines, so that a vehicle can cross the line from one line to another line. This step is an off-line tool, so it only needs to be run once, and finally generates the corresponding data for the simulation locomotive to read.
Step S3: this is a beacon offline tool, which takes LEU data of a plurality of lines as input, and merges all beacon data by the same ID processing method in S2. And simultaneously, calculating a corresponding beacon message for each beacon according to different LEU input combinations. As shown in table 1:
TABLE 1
The data generated by the table is read by the simulation locomotive, the simulation locomotive knows the real-time position of the simulation locomotive in each period, whether the period passes through the beacon can be inquired according to the line map, and if the period passes through the beacon, which message is sent to the vehicle-mounted CC is selected from the upper table according to the state of the trackside equipment sent by the simulation trackside equipment.
Step S4: this is a simulated driver's cab module, which is used primarily to simulate some of the operating buttons on a real driver's cab, which are connected to the simulated locomotive through a test net. The simulation driving platform sends an operation button command to the simulation locomotive (such as KSON, a direction handle, a traction brake handle and the like) in real time every period, and the simulation locomotive feeds back the state of the operation button to the simulation driving platform in real time every period (such as an ATO departure allowing indicator lamp, a door opening and closing allowing indicator lamp, an RM indicator lamp and the like). The simulation bridge is only communicated with the simulation locomotive, because the simulation locomotive generally runs in the real-time controller, the simulation bridge can be regarded as an upper computer of the simulation locomotive.
Step S5: in the initialization process, the simulation locomotive reads the line map data (including all lines) generated by the off-line tool in the steps S2 and S3, initializes some variables, and initializes some hardware boards transmitting the odometer waveform, the beacon waveform and the IO code bits.
Step S6: the displacement calculation process is that the simulated locomotive calculates the displacement of the period according to the acceleration command sent by the simulated driving platform or the vehicle-mounted CC, and the acceleration comes from the traction brake handle on the simulated driving platform in the non-ATO mode and the acceleration comes from the vehicle-mounted CC in the ATO mode.
Step S7: this is a train position updating process, and the simulation locomotive of each period calculates the position of the train after the period in real time according to the initial position of the train in the period and the displacement of the period calculated in the step S6. In the process of updating the position, if the switch is passed, the position of the train needs to be calculated through the switch state received from the simulated trackside equipment every period. Meanwhile, the simulation locomotive needs to send the position of the whole train to the simulation trackside equipment in real time in each period, and the simulation trackside equipment calculates the occupation and clearing states of the axle according to the position of the train.
Step S8: since the simulation locomotive is connected to the on-board CC through a hard-wire interface, the on-board CC needs to convert the displacement of the current period calculated in S6 into a pulse signal and output the pulse signal to the on-board CC, and the on-board CC can calculate the displacement and speed information of the train by processing the pulse signal.
Step S9: the IO code bit simulation module is an IO code bit simulation module of the vehicle-mounted CC, and some IO code bit interaction exists between the real vehicle-mounted CC and the train. For example, the key KSON of a certain end is activated by operating on the simulation driving platform, the simulation driving platform sends the information to the simulation locomotive, the simulation locomotive outputs the corresponding code position 1 to the vehicle-mounted CC according to the interface document of the vehicle and the signal, and after the vehicle-mounted CC acquires the code position, the key KSON of the certain end can be known to be activated. Similarly, when the vehicle-mounted CC obtains that the ATO is available through internal calculation, the corresponding departure button indicator light code position can be output, the simulation locomotive sends the code position information to the simulation driving platform, and then the corresponding ATO departure button on the simulation driving platform can be lightened or flickered.
Step S10: this is a beacon simulation module, which queries whether the beacon has passed through this period, based on the position information of the train passing through this period calculated in S7 and the route map read in the initialization process. If not, this step can be skipped directly. If the beacon passes through the period, judging whether the beacon is a passive beacon or an active beacon, and if the beacon is the passive beacon, directly generating a corresponding beacon message according to a rule and outputting the beacon message to the vehicle-mounted CC; and if the active beacon is the active beacon, screening out a corresponding beacon message according to the beacon screening table read in the initialization process and the state of the trackside equipment read from the simulation trackside equipment in each period, and outputting the beacon message to the vehicle-mounted CC. After the vehicle-mounted CC analyzes the information in the beacon, the current position of the train can be known according to the route map stored by the vehicle-mounted CC.
Step S11: the vehicle-mounted CC is a tested object and is only directly connected with the simulation locomotive through a hard wire interface, and the simulation locomotive transmits the speed sensor waveform simulated in S8 and the beacon waveform simulated in S10 to the vehicle-mounted CC through hardware; and meanwhile, acquiring output code bit information of the vehicle-mounted CC, obtaining input code bit information of the vehicle-mounted CC through logical operation, and transmitting the input code bit information to the vehicle-mounted CC. The simulation locomotive is tightly connected with the vehicle-mounted CC.
Step S12: this is a simulated trackside offline tool. The tool takes the system data and the interlocking data as input, and recalculates the IDs of the related trackside equipment in all the lines by using the same method in S2 and combines the IDs into the data of one line. And the trackside devices in the system data and the interlocking data are mapped. And the generated off-line data is read by the simulation trackside equipment.
Step S13: this is the initialization process of the simulated trackside equipment. During initialization, the simulation trackside device reads all data generated by the simulation trackside offline tool in S12 and initializes the relevant variables.
Step S14: this is the process of receiving interlocked output code bit information from the emulated trackside device. For the simulation interlocking, the simulation trackside equipment directly receives the interlocked output code bit information through a network protocol; for the real interlocking, the test system can acquire interlocked output code bit information through the PLC or other equipment, and the simulation trackside equipment acquires the interlocked output code bit information through network communication with the PLC.
Step S15: this is the logic processing module of the simulation trackside equipment. The simulation trackside equipment needs to be capable of simulating trackside equipment such as turnouts, signal machines and the like. The turnout is taken as an example for explanation, the operation of arranging the route is carried out on the ATS, the ATS issues the route information to the interlock, the interlock checks whether the route condition is met according to the rule of the interlock, if the route condition is met, the corresponding turnout arrangement route is operated, for example, a certain turnout is moved from a positioning position to a reverse position, the output code bit corresponding to the interlock drives the corresponding relay to drive the turnout machine to act, and meanwhile, the interlock can recover the state of the turnout machine in real time. In the test system, the interlocks can output all output code bits to the simulation trackside equipment in real time, and the simulation trackside equipment obtains the information of all input code bits of the interlocks through logic calculation and sends the information to the interlocks.
Step S16: this is the interaction process of the simulated trackside equipment and the simulated locomotive. And the simulation trackside equipment acquires the position information of the train from the simulation locomotive in real time in each period, calculates the occupation and clearance states of the axle according to the system data read in the initialization process, and updates the interlocked input code bit information. Meanwhile, the simulated trackside equipment sends the states of all trackside equipment such as the turnouts, the signal machines and the like calculated in the step S15 to the simulated locomotive, so that the simulated locomotive updates the position of the train and screens beacons.
Step S17: the method is a process that the simulation trackside equipment sends interlocking input code bit information to the interlocking. The emulated trackside device updates the interlock' S input code bit information in S15 and S16, which is sent to the interlock in real-time per cycle. For the simulation interlocking, the simulation trackside equipment directly sends all updated input code bit information to the interlocking through a network protocol; for real interlocking, the simulation trackside equipment sends corresponding input code bit information to acquisition equipment such as a PLC (programmable logic controller) through a network, and the PLC can drive corresponding output code bits to be acquired in an interlocking manner.
Step S18: this is the device under test interlock CI. The simulated trackside equipment is tightly connected with the interlock. The interlock sends all output code bit information of the interlock to the interlock in real time, and receives all input code bit information calculated by the simulation trackside equipment.
While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
