In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an electronic map data error detection method according to an embodiment of the present invention, and as shown in fig. 1, an embodiment of the present invention provides an electronic map data error detection method, including:
101. and after receiving the electronic map checking instruction, setting the starting time of the application period.
The electronic map checking instruction may be an instruction automatically loaded when the CBTC signal system is initialized (e.g., booting and restarting), or an instruction received during the operation of the system. In this embodiment, the time for performing the verification is divided into application cycle time slices. And when the instruction is received and the verification is started, starting a timer of an application period, wherein the starting time of the application period is the starting time of the first application period. In this embodiment, for each application cycle, a partial verification operation of the electronic map is performed separately.
102. And detecting whether the processor is idle, if so, executing electronic map verification, and interrupting the verification and acquiring interruption point information after a preset application period is reached.
At present, the storage format of the electronic map includes a header of the electronic map, where the header includes a header address of each sub-table and the number of entries of each sub-table. And configuring a two-stage relative address table aiming at the electronic map, wherein the first-stage relative address table of the electronic map mainly aims at a table head, and the second-stage relative address table of the electronic map mainly aims at entries in a sub-table.
Electronic map data can be classified into the following categories: line data, track section data, trackside equipment data, and secure communication protocol data. The verification of the line data with respect to the electronic map mainly includes saving an array start position, an array element number, and a CRC check code of each sub-table (e.g., a track segment list) in each sub-table, so as to obtain an absolute start address of each entry in the electronic map stored in the memory. The discontinuity information can be expressed by structural elements and can be divided into two categories:
absolute address: the index values are mainly recorded as subscripts in an array of a plurality of electronic maps (namely index numbers of the electronic maps), array subscripts of sub-tables in a table head relative address data table (namely sub-table indexes of items to be detected) and index values in the sub-tables.
Relative address: the subscript of the entry element of the sub-table in the entry-to-address data table, that is, the offset of the protocol data from the entry address, is mainly recorded.
At the starting time of the application period, namely the beginning of the first application period, whether the processor is in an idle state is judged, if so, the absolute address of the electronic map in the memory is acquired, and the electronic map is verified. After the time of the first application period is reached, part of sub-entries of the electronic map are verified at the moment, and the checking and recording of the interruption point information are interrupted.
103. For each subsequent application period: and detecting whether the processor is idle, if so, acquiring the current item address to be verified according to the interrupt point information of the previous application period, and continuously executing the electronic map verification according to the item address to be verified until the current application period is reached, and interrupting the verification and acquiring the interrupt point information.
In the time slice of each application period, when the period starts, whether the processor is in an idle state currently is detected, namely, resources are available for checking the electronic map. If so, acquiring the address of the sub-entry to be checked according to the related information recorded by the break point in the last period, and determining according to the sub-table index of the entry to be checked and the index value in the sub-table. And reading the data part of the entry from the memory according to the address of the entry to be verified, and checking according to protocol data and CRC in the data part. And when the current application cycle time slice is finished, interrupting the current verification operation, and recording interruption information at an interruption point, wherein the interruption information is used for acquiring address information of the sub-entry to be verified in the next application cycle.
According to the electronic map data error detection method provided by the embodiment of the invention, the electronic map verification is executed when the detection processor is in an idle state, so that the problem that the application cycle time is too long for verifying the validity of the electronic map data is avoided, and the system task scheduling is not influenced by the electronic map verification. And acquiring the current item address to be verified according to the interruption point information, and continuously executing the electronic map verification according to the item address to be verified, so that the continuity of verification in each application period can be effectively ensured.
Based on the content of the foregoing embodiment, as an optional embodiment, before detecting whether the processor is idle, the method further includes: creating a priority for each system task, and checking the task priority to be the lowest by the electronic map; correspondingly, whether the processor is idle is detected, specifically: and if only the electronic map checking task in the system is detected to be in a ready state, the processor is idle.
In order to perform reasonable detection of the idle state of the processor, a priority is created for each task in the embodiment, and the priority for detection of the electronic map is set to be the lowest. After each application period is started, if it is detected that only the electronic map checking task is in a ready state, which indicates that other tasks are in an execution state or a sleep state, and the processor has idle resources, the processor is judged to be idle. At the moment, the electronic map verification is executed, and processor resources are not occupied additionally.
Based on the content of the foregoing embodiment, as an optional embodiment, if it is detected that the high-priority task is scheduled, the interrupt checking is performed, and the interrupt point information is obtained.
Fig. 2 is a schematic diagram of priority scheduling according to an embodiment of the present invention, and as shown in fig. 2, the high-priority task is a task other than the electronic map checking task. In an application period, if the high-priority task is detected to be scheduled and executed, the electronic map checking task is blocked, so that the electronic map checking is interrupted, and processor resources are released. Through the process, the operation of the high-priority task is guaranteed, and the high-priority task is not influenced by the verification of the electronic map. And meanwhile, when the electronic map is interrupted for verification, the interruption point information needs to be acquired and used for the next application cycle time slice, and the electronic map is continuously verified according to the recorded interruption point information.
In the embodiment of the invention, the checking is interrupted and the interruption point information is obtained by detecting that the high-priority task is scheduled, so that the electronic map checking does not occupy the processor resources of other tasks, and the system task scheduling is further optimized.
Based on the content of the above embodiment, as an optional embodiment, the breakpoint information includes an electronic map index number and a relative address of an entry to be verified; correspondingly, the current entry address to be checked is obtained according to the interruption point information, which specifically comprises the following steps: acquiring an initial address of the electronic map according to the index number of the electronic map; and acquiring the address of the current item to be verified according to the first address of the electronic map and the relative address of the item to be verified.
An interruption point recording table can be set for storing the index number of the electronic map and the relative address of the entry to be verified. For example, the offset address of the structuring element from the first address of the structuring is obtained based on the C language structuring principle.
One specific example is shown in table 1, where table 1 is a break point record table.
TABLE 1
The INDEX1 is an electronic map INDEX number, and the INDEX2-INDEX4 is used for acquiring the relative address of the item to be verified. Fig. 3 is a flowchart of an interruption point recovery according to an embodiment of the present invention, as shown in fig. 3.
Considering a plurality of electronic maps, the determined INDEX number of the electronic map can be obtained according to INDEX1, so that the first address of the electronic map can be found in the memory. After the first address of the electronic map is determined, the absolute address of the item to be verified can be determined according to the relative address of the item to be verified. In the implementation of FIG. 3, the process of obtaining the relative address of the entry to be verified is based on INDEX2-INDEX 4.
The method of the embodiment can obtain the relative position of each element of the entry in the memory and can effectively reduce the complexity of the program.
Based on the content of the above embodiment, as an alternative embodiment, the breakpoint information further includes a relative address of the entry element; correspondingly, according to the address of the current item to be verified, the electronic map verification is continuously executed, and the method comprises the following steps: acquiring the absolute address of the entry element according to the relative address of the entry element; and converting the protocol data corresponding to the entry element into a byte stream, and checking the electronic map.
Referring to INDEX5 of fig. 3, the subscript INDEX5 of the entry elements in the relative address table indicates the offset of the data portion of the entry to be verified relative to the entry address. After the entry address is determined, an entry element part needs to be extracted, and the protocol data recorded in the element part is a part needing to be checked. And converting the protocol data into a byte stream, and checking whether the CRC check code of the byte stream is legal or not, thereby finishing the checking process of the item.
Based on the content of the foregoing embodiment, as an optional embodiment, if it is detected that the verification of the last entry of the last electronic map is completed, the verification of the electronic map is terminated.
And if the electronic map only needs to be checked once, stopping checking the electronic map when the last item of the last electronic map is checked.
Based on the content of the foregoing embodiment, as an optional embodiment, if it is detected that the verification of the last entry of the last electronic map is completed, the verification is restarted with the first entry of the first electronic map as a break point.
In the conventional method, after the validity of the electronic map data is checked in the first period of application, the validity of the electronic map data is not checked any more. The method can not timely know the validity of the electronic map when the validity of the electronic map is abnormal after the first period. In the embodiment, the method can be repeatedly executed in each application period, and the processor overhead of the system is not occupied, so that the reliability of the verification of the electronic map is further ensured, and the system safety can be effectively improved.
As an optional embodiment, on the premise that the train has positioning, when the train returns to the warehouse, the electronic map of the train returning to the warehouse can be recorded first, and when the train leaves the warehouse next time, the electronic map of the train returning to the warehouse can be verified first.
The following is illustrated by two examples:
example 1, electronic map verification based on application of periodic time slices.
The electronic map is stored in a data section of the executable program.
Configuring a plurality of electronic maps and configuring the time of a timer.
When the time of the periodic timer is up, the checked address of the current electronic map and the item to be verified in the interrupt point recording table are recorded.
And when the next cycle of application tasks is used for verifying the electronic map, continuously verifying the items to be verified at the break points of the above cycle verification.
The fault caused by the overtime check of the electronic map does not occur in the process.
Example 2, based on CPU idle check.
And configuring an error electronic map.
The electronic map checking task is used as the lowest priority task, and when other high priority tasks are changed from a blocking state or a dormant state to a ready state, the low priority tasks are interrupted to run, and the existing system scheduling mechanism is not influenced.
And (3) the application period is powered on to default to start the electronic map verification, and if the electronic map is detected to be wrong based on the task with the lowest priority in the running process of the train, the train is down.
