Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Aiming at the defects of two existing data storage methods in the prior art, the embodiment of the invention provides an interlocking data monitoring and storing method based on a data double-check and index registration mechanism, which is applied to an interlocking monitoring machine and ensures the accuracy and the time sequence of data in the real-time storage process of interlocking data so as to facilitate interlocking product maintenance personnel to analyze the playback of historical phenomena in the later stage of failure.
In the rail transit interlocking system, as the interlocking software runs in the lower computer security computer Dos system, the running memory is very small; the upper computer interlocking control and display machine needs to process a large amount of uplink and downlink data, so that an interlocking system is generally provided with a set of interlocking monitoring machines, operates on a single machine and is responsible for real-time recording, storage, display and real-time alarm processing of interlocking data. Therefore, when the interlocking system has a fault, the historical operating conditions can be played back through the interlocking monitoring machine, so that the interlocking product personnel can analyze the fault problem conveniently. Therefore, the storage and recording function for the interlocking data requires the accuracy and the time sequence of the storage and the preservation of the data.
The interlocking monitoring machine program provided by the embodiment of the invention comprises a data receiving and storing process and a real-time display process, wherein a data receiving part mainly receives original logic operation data of an interlocking system through an Arcnet communication card, and then the data receiving part is divided into two paths, one path of data is stored in a local hard disk in a binary format in real time, and the other path of data is transmitted to the real-time display process for display processing in a shared memory mode of inter-process communication, the whole architecture of the interlocking monitoring machine program is shown in figure 1, the problem of data storage error caused by various software abnormalities due to the fact that data is not checked in the process is mainly solved; and the data index has some dislocation because of timing, which brings obstacle to the analysis of fault problem.
Fig. 2 is a flowchart of a method for storing interlocking monitoring data according to an embodiment of the present invention, as shown in fig. 2, including:
s1, starting the program to be stored, and receiving a first data packet to be stored;
s2, recording the data length of the first data packet to be stored, and writing a first index number corresponding to the first data packet to be stored into a registry;
s3, calculating a cyclic redundancy check value corresponding to the first data packet to be stored, and recording the cyclic redundancy check value as a cyclic redundancy check variable;
s4, storing the first data packet to be stored and the associated data information of the first data packet to be stored as binary files;
s5, receiving a second data packet to be stored according to a preset period interval;
and S6, before the second data packet to be stored is stored, the length of the stored data and the cyclic redundancy check value are respectively checked, and the second data packet to be stored is stored if the length of the stored data and the cyclic redundancy check value pass the check.
Specifically, when the storage program is started for the first time, that is, the storage program starts to receive the interlock logic data periodically, when receiving a first packet of data, a Cyclic Redundancy Check (CRC) calculation is performed on the received data once, the data length of the data packet and a corresponding CRC Value variable Value are temporarily recorded, the first packet of data is stored in a local hard disk in a binary form in real time, and the Index number of the data is recorded as Index and written into a system registry.
Starting to receive second packet data, reading the total length of a data packet stored in a local hard disk before storing, performing CRC value check if the total length of the data packet is consistent with the total length of the data packet, otherwise, clearing the tail data of the stored data according to a certain length, writing the binary format of the second data packet, recording the Index number of a mark corresponding to the Index number as Index +1 and writing the Index number into a system registry; and if the CRC Value is inconsistent with the updated CRC Value variable Value in the CRC Value checking process, writing the second packet data into a local hard disk for storage, updating the binary file, and if the updated CRC Value variable Value is inconsistent with the updated CRC Value variable Value, deleting the data stored in the previous period according to the preset data length.
The embodiment of the invention adopts the interlocking monitoring data storage method based on the data double check and the index registration mechanism, so that the stored data are correct and effective data, the accidentally modified error data cannot be stored, the absolute time sequence is realized in the time sequence, and the stored data cannot be out of order or disordered due to the error of a clock or time correction.
Based on the above embodiment, the method further comprises:
and when the storage program is restarted, reading and referencing the index number in the registry.
Specifically, in the process of storing and verifying data, the index numbers corresponding to the data packets are written into the registry, and when the system is restarted each time, including manual restart or restart caused by program accidents, the index values in the registry are read before the stored program starts to run again, so that the data timing sequence is guaranteed not to be disordered even if the clock is disordered or corrected.
Based on any of the above embodiments, step S4 in the method specifically includes:
storing the first data packet to be stored, the first time information, the first index number and the first data frame tail information in a temporary array;
and storing the temporary array as the binary file.
Specifically, in order to conveniently record the relevant information of each data packet to be stored, temporary data is established to store the relevant information, the storage comprises the data packet to be stored, time information, index number and data frame tail information corresponding to the data packet, and the time information, index number and data frame tail information are written into a local hard disk space in a binary format to be stored, so that a binary file is formed.
Based on any of the above embodiments, step S6 in the method specifically includes:
setting the data length of the first data packet to be stored as a preset data length;
if the length of the stored data is judged to be integral multiple of the length of the preset data, checking the cyclic redundancy check value of the stored data;
and otherwise, deleting tail data of the stored data in the previous period, wherein the length of the tail data is a remainder value of the length of the stored data and the length of the preset data.
Wherein, step S6 in the method further includes:
calculating the cyclic redundancy check variable after the cyclic redundancy check value of the stored data is correspondingly updated;
if the updated cyclic redundancy check variable is judged to be consistent with the cyclic redundancy check variable, storing the second data packet to be stored, and updating the binary file;
otherwise, deleting tail data of the stored data in the previous period, wherein the length of the tail data is the preset data length.
Specifically, the data length of the received first packet to be stored is set as a preset data length based on the data length. Firstly, checking the length (offset) of stored data, if the length of the stored data is judged to be integral multiple of the length of the preset data, carrying out next CRC check, if the length of the stored data is judged not to be integral multiple, deleting redundant data, namely deleting tail data of the stored data in the previous period, wherein the length of the deleted tail data is obtained by carrying out remainder operation on the length of the stored data and the length of the preset data.
In the process of performing CRC, firstly, a cyclic redundancy check variable Value after the stored data is updated is obtained through calculation and is compared with a previous cyclic redundancy check variable Value, if the two variables are judged to be consistent, a newly received data packet, namely a second data packet to be stored is locally stored, a binary file is updated, if the two variables are judged to be inconsistent, tail data of the stored data in the previous period is deleted, the deleted tail data length is a preset data length, and the deletion is equivalent to the whole deletion of the previous data packet.
The embodiment of the invention performs double check on the data length and the CRC value based on the identification index number, ensures that the data length is checked before the data is stored, can prevent the data from being partially lost, and simultaneously performs CRC check on the stored data, and prevents the error data after the data is accidentally tampered from being stored.
Taking the urban rail transit signal system DS6-60 interlocking subsystem as an example, the interlocking logic sends 28000 bytes of data to the interlocking monitor in real time at a period of 250 ms. The monitoring machine stores the interlocking data in real time so as to analyze the problems in the playback of historical conditions at a later stage.

step 2: recording the Index number of the data at this time as 0, and writing the Index number into a registry;
step 3: storing the 28000 bytes of data, time information (24 bytes), data Index number Index (int type 4 bytes) and data frame end information (4 bytes) into a temporary array tmp _ data [28000+24+4+4] for storage, totaling 28032 bytes of data, and writing the 28000 bytes of data into a local hard disk space in a binary format for storage to form a binary dat file;
step 4: when 28000 bytes of interlocking data of the second period are received, recording the Index number of the data at this time as Index +1 and writing the Index number into a registry;
step 5: before storing data, judging whether the length of the stored data is an integral multiple of N, if so, executing Step 6; otherwise, executing Step 7;
step 6: calculating a CRC value NewCRCValue of the stored data, comparing the CRC value NewCRCValue with the CRCValue value, and if the CRC value NewCRCValue is consistent with the CRCValue value, executing Step 9; otherwise, executing Step 8;
step 7: deleting the data stored in the previous period, and deleting data at the tail part of the data, wherein the length is a remainder value of the total length N of the stored data and the length N of a single period;
step 8: deleting the data stored in the previous period, and deleting the data with the tail length of N bytes;
step 9: writing 28032 bytes of new periodic data into the local hard disk space for storage, and updating the binary dat file;
step 10: cycling from Step4 to Step 9;
step 11: and after the program is restarted accidentally or manually, reading the data Index number in the registry and assigning the data Index number to Index, and then executing Step 4-Step 9 in a circulating manner.
