Description

Technical Field

[0001] The present invention relates to the field of railway signals, and in particular to a method, system, equipment and medium for verifying the security of interlocking dual-channel collected information. Background Art

[0002] When a new line is connected to an existing line, the computer interlocking equipment of the new station needs to collect the relay information of the station connected to the existing line, and at the same time output the information content driven by this station to the adjacent station. Most of the collected information exchanged between the two stations is key information related to driving safety, which is the object of the present invention.

[0003] At present, there are usually two ways for computer interlocking equipment to collect relay information:

[0004] First: For the key information used for interlocking logic, for example, the track relay GJ indicating the track circuit occupancy status needs to collect its front and rear contacts, such as Figure 1 , and perform XOR operation inside the interlocking system (NLCB in the figure is a control unit in the interlocking). XOR, its operation rule is equivalent to binary addition without carry: 1 represents true, 0 represents false, then the XOR operation rule is: 0⊕0=0, 1⊕0=1, 0⊕1=1, 1⊕1=0 (same is 0, different is 1). XOR operation is used to determine whether two variables are different. Figure 1 Middle: The interlocking system collects the front and rear contact information of the track relay GJ. The meanings of these two contact information are mutually exclusive. When 10 is collected, it is valid information, indicating that the front contact of the track relay GJ is collected and the rear contact of GJ is not collected, indicating that the track circuit is idle; when 01 is collected, it is valid information, indicating that the rear contact of the track relay GJ is collected but the front contact of GJ is not collected, indicating that the track circuit is occupied. When 00 or 11 is collected, it is fault information. According to the "fail-safe" principle of railway signals, the track circuit should be output externally to indicate occupation.

[0005] Second: key information for non-interlocking logic. Figure 2 The interlocking system collects the signal machine filament relay information DJ. It only needs to collect its front contact. If 1 is collected, it means that the signal machine filament is intact, and if 0 is collected, it means that the signal machine filament is broken.

[0006] At present, the interlocking device handles two mutually exclusive information (such as the front and rear contacts of GJ) in the following way: if 10 or 01 is collected, it is valid; if 00 or 11 is collected, a fault should be output; after 01 or 10 is collected again, it is directly considered valid and output. However, this method has certain safety risks.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The purpose of the present invention is to provide an interlocking dual-channel information collection security verification method, system, equipment and medium. After the fault is restored, it is necessary to undergo re-verification to determine whether the information is valid, thereby improving driving safety.

[0009] The objective of the present invention is achieved through the following technical solutions:

[0010] An interlocking dual-channel collection information security verification method, comprising:

[0011] Receive computer interlock dual-channel acquisition information and filter out the information that needs to be safety checked;

[0012] Determine whether the information that needs to be security-verified is valid information or fault information, and complete the information security verification based on the determination result;

[0013] If it is valid information, and it has been valid information for multiple consecutive cycles before, then the valid information will be directly output;

[0014] If it is fault information, then output the fault information;

[0015] If it is valid information and the previous cycle was fault information, then the fault information is output; if it is valid information and the previous cycle was valid information received after a fault and the content is different from the information being security-checked this time, then it is output as valid information.

[0016] An interlocking dual-channel information collection safety verification system, comprising:

[0017] Information receiving and screening unit, used to receive computer interlocking dual-channel acquisition information and screen out information that needs to be safety checked;

[0018] An information security verification unit is used to determine whether the information that needs to be security verified is valid information or fault information, and complete the information security verification based on the judgment result; if it is valid information, and it has been valid information for multiple consecutive cycles before, the valid information is directly output; if it is fault information, the fault information is output; if it is valid information, and it was fault information in the previous cycle, the fault information is output; if it is valid information, and the previous cycle was valid information received after the fault, and the content is different from the information that is being security verified this time, it is output as valid information.

[0019] A processing device, comprising: one or more processors; a memory for storing one or more programs;

[0020] When the one or more programs are executed by the one or more processors, the one or more processors implement the aforementioned method.

[0021] A readable storage medium stores a computer program, which implements the above method when the computer program is executed by a processor.

[0022] It can be seen from the technical solution provided by the present invention that when the interlocking output fails, the valid information received again cannot be fully trusted and used immediately, but needs to be verified again and can only be used after the verification is correct, so as to avoid the safety hazards existing in the existing solution.

For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0036] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them.

[0037] The following is a detailed description of an interlocked dual-channel information collection security verification method, system, device and medium provided by the present invention. The contents not described in detail in the embodiments of the present invention belong to the prior art known to professional and technical personnel in the field.

The instruments used in the embodiments of the present invention, if the manufacturer is not specified, are all conventional products that can be purchased commercially.

[0038] Embodiment 1

[0039] The embodiment of the present invention provides a method for verifying the security of information collected through an interlocking dual-channel. Figure 3 As shown, it mainly includes the following steps:

[0040] Step 1: Receive computer interlock dual-channel acquisition information and filter out the information that needs to be safety checked.

[0041] Step 2: Determine whether the information that needs to be security-checked is valid information or fault information, and complete the information security check based on the judgment result.

[0042] The main process is as follows:

[0043] If it is valid information, and it has been valid information for multiple consecutive cycles before, then the valid information will be directly output;

[0044] If it is fault information, then output the fault information;

[0045] If it is valid information and the previous cycle was fault information, the fault information in the fault buffer area will still be output; if it is valid information and the previous cycle was valid information received after the fault, and the content is different from the information being security checked this time, it will be output as valid information this time.

[0046] In the above-mentioned solution provided by the embodiment of the present invention, when the interlock output fails, the valid information received again cannot be fully trusted and used immediately, but needs to be verified again and can only be used after the verification is correct, so as to avoid the safety hazards existing in the existing solution.

[0047] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the method provided by the embodiment of the present invention is described in detail with reference to specific embodiments below.

[0048] 1. Introduction to the principles of the plan.

[0049] In the embodiment of the present invention, an XOR operation is performed on the dual-channel collected information to determine whether the two are different. If they are different, it is valid information; if they are the same, it is fault information. The principle flow of the relevant safety verification can be described as follows:

[0050] (1) If valid information is received all the time, it will be output directly.

[0051] (2) When fault information is received, the fault information is output.

[0052] (3) When valid information is received, if the last time was fault information, that is, the current valid information is the first normal reception after the fault information, the fault information in the fault buffer area is still output.

[0053] (4) The valid information received is the valid information received for the second time after the fault information is received, and the valid information is different from the first valid information. If both conditions are met, the valid information received this time can be output. That is, after the system receives the fault information, it receives two consecutive valid information with different values, and then it is considered that the second valid information can be output.

[0054] According to the above working principle, corresponding examples are provided for illustration.

[0055] like Figure 4The figure shows a schematic diagram of dual-channel acquisition of the ZCJ relay. The ZCJ relay is used to indicate the hostile relationship between the routes between two stations. It is a key relay involved in driving safety. The interlocking system will collect the status of its front and rear contacts (i.e., ZCJQ and ZCJH) through its NLCB board. There are two possibilities for each contact of ZCJQ and ZCJH: "Not collected" (status "0") or "Collected" (status "1"). When the status of the ZCJQ and ZCJH contacts collected is 01 or 10, it is valid information and is output normally. When the status of the ZCJQ and ZCJH contacts collected is 00 or 11, it is considered that the front and rear contacts are not collected at the same time or the front and rear contacts are collected at the same time, and both are considered as fault information. After the first fault, when the interlocking system receives valid information of 10 or 01 again, it does not consider that the valid information can be output and used immediately, and the fault information output will be maintained; only when the valid information of 01 or 10 is received for the second time and is different from the valid information for the first time, the 10 or 01 received for the second time will be considered as valid information that can be output again.

[0056] 2. Implementation details of the solution.

[0057] 1. Storage area.

[0058] In the embodiment of the present invention, three storage areas are set, such as Figure 5 As shown, it mainly includes:

[0059] (1) Fault buffer area, used to store fault information 11 or 00, including high and low digits, each digit corresponds to the collection information of a channel. For example, 11 means that the collection information of two channels is 1, and 00 means that the collection information of two channels is 0.

[0060] (2) Data buffer area, used to store valid information, including high and low digits. Each digit corresponds to the acquisition information of a channel. For example, 10 means that the acquisition information of the first channel is 1, and the acquisition information of the second channel is 0; 01 has a similar meaning.

[0061] (3) Status area, including three states, represented by values ​​0, 1, and 2. The first state is valid information (value is set to 0), the second state is the first time fault information is received (value is set to 1), and the third state is the first time valid information is received after fault information (value is set to 2).

[0062] Based on the aforementioned principle, the state changes of each storage area during the security verification process are as follows:

[0063] (1) If it is valid information, and the previous multiple consecutive cycles have been valid information, then the current valid information is directly output. During this process, the data buffer area stores the corresponding valid information, and the status area is set to 0, indicating the valid information state.

[0064] (2) If it is fault information, the fault information is output. During this process, the fault buffer area stores the fault information and the status area is set to 1.

[0065] (3) If it is valid information and the previous cycle was fault information, the fault information is still output. During this process, the data buffer area stores the corresponding valid information and the status area is set to 2, indicating that the valid information is received for the first time after the fault.

[0066] (4) If it is valid information, and the previous cycle is valid information received after the failure, and the content of the information being safety-checked this time is different from the information in the data storage area, then it is output as valid information this time.

[0067] like Figure 6 As shown, an example of the state change process of the storage area is shown. When 11 is received, it is determined to be fault information, the fault information is output, the state area is set to 1, and 11 is stored in the fault buffer area; after that, valid data (01) is received for the first time, fault information is also output, the state area is set to 2, and 01 is stored in the data buffer area; thereafter, valid data (10) is received for the second time, which is different from the valid data received for the first time, so the valid data is output and the data buffer area is cleared.

[0068] 2. Security data verification example.

[0069] Taking the aforementioned check relay (ZCJ) as an example to introduce the safety verification process, based on the above scheme, a corresponding safety verification program (sfmeschk.c program) can be compiled, and then combined with relevant configuration data, the sfmeschk.c program is called through interlocking each cycle operation to realize cyclic verification of safety information. Figure 7 As shown, the main process includes:

[0070] (1) Data acquisition, corresponding to step ①, the computer interlocking program receives all information data from the outside (i.e., obtains the sharet_g.input[] value).

[0071] (2) Filtering information, corresponding to step ②, select the pre-defined information in the external information data that needs to be security-checked, such as selecting the front and rear contacts of ZCJ.

[0072] (3) Whether the received information is 11, corresponding to step ③, determine whether the ZCJQ and ZCJH safety information is 11. If so, the received information is fault information, and step ⑩ is executed to store the high-order and low-order data in the fault buffer area for subsequent comparison with the received information. At the same time, the status area is set to 1, and the program directly outputs 11. If not, step ④ is executed.

[0073] (4) Whether the received information is 00, corresponding to step ④, execute the judgment whether the ZCJQ and ZCJH information are in the 00 state. If so, execute step Timing is performed. If it is within the time range allowed by the computer program running cycle, the result is directly output. If it exceeds the cycle range, it is regarded as a fault state and the data is placed in the fault buffer area for subsequent comparison with the received information. At the same time, the status area is set to 1, and the program directly outputs 00; if not, execute step ⑤.

[0074] (5) Whether the value in the status area is 0, corresponding to step ⑤. After the previous judgment, it can be determined that the information received this time is valid information (01 or 10). The program then checks whether the fault buffer area is empty and the status area is 0. If so, the valid information 10 or 01 received this time can be directly output; if not, the program checks whether the value in the status area is 1 to continue to determine whether it is the first time to receive valid information after the fault).

[0075] (6) Whether the value in the status area is 1, corresponding to step ⑥. After the program receives 10 or 01, it determines whether this is the first valid information received after the fault by judging whether the status area is 1. If so, this is the first valid information received after the fault, and the information is still unavailable. The valid information needs to be temporarily stored in the data buffer, and the value in the status area is set to 2. The program still outputs the fault information in the fault buffer area to the outside world; if not, continue to judge whether it is state 2 (the first time valid information is received after the fault).

[0076] (7) Determine whether the value in the status area is 2, corresponding to step ⑦. After receiving 10 or 01, the program determines whether the value in the status area is 2. If not, the information is fault information, and the fault information in the fault buffer area is output; if so, execute step ⑧.

[0077] (8) Compare the high and low bit data to see if they are different from those in the data cache, corresponding to step ⑧. Compare the current valid information with the data in the data cache. If they are consistent, they do not meet the requirements and are considered to be faulty. Output the fault information in the fault cache. If they are inconsistent, execute step ⑨.

[0078] (9) Clear: The program outputs the received valid information to the outside. At the same time, the data buffer and fault buffer are cleared, the status area is set to 0, and the counter cycle count is cleared.
